Agricultural Machinery Steering Axle Reinforcing Beam Welding Fixture

Technical Field

The utility model belongs to the technical field of agricultural machinery equipment, and more particularly relates to an agricultural machinery steering axle reinforcing beam welding fixture.

Background Technology

The agricultural machinery steering axle reinforcing beam is an important component of the agricultural machinery steering axle. It is formed by enclosing the vertical beams and the top plate of the reinforcing beam. Since the top plate of the reinforcing beam has an arc shape, technical difficulties exist during positioning and welding.

If the arched surface of the top plate is not accurately positioned, positional errors will occur between the top plate and the vertical beams. As a result, welding errors may occur after welding, causing the reinforcing beam to fail to match the agricultural machinery steering axle.

Utility Model Content

To solve the above problems and overcome the deficiencies of the prior art, the utility model provides an agricultural machinery steering axle reinforcing beam welding fixture.

The technical problem solved is that inaccurate positioning of the arched surface of the top plate may cause positional errors relative to the vertical beams, resulting in welding errors and failure to match the agricultural machinery steering axle.

The agricultural machinery steering axle reinforcing beam welding fixture includes an operating platform. Along the depth direction of the operating platform, a preset number of positioning plates are arranged at equal intervals on the upper end surface of the operating platform. A supporting vertical plate assembly is inserted into the positioning plates.

The supporting vertical plate assembly includes two side vertical plates and a lifting vertical plate arranged between the two side vertical plates. The upper end surface of the supporting vertical plate assembly is provided with an arched surface matched with the lower end surface of the top plate of the agricultural machinery steering axle reinforcing beam. Limiting sections matched with the top plate are arranged on both sides of the arched surface.

On the upper end surface of the operating platform, on both sides of the two side vertical plates, jackscrew plates are arranged at equal intervals. Jackscrew bolts are threaded through the jackscrew plates in the horizontal direction and cooperate with the outer end surfaces of the vertical beams.

Limiting blocks are arranged at both ends of the side vertical plates, and the limiting blocks cooperate with the front and rear end surfaces of the vertical beams.

Further, the lifting vertical plate and the side vertical plates are connected through isolation connecting blocks.

Further, the lifting vertical plate and the side vertical plates are connected with the isolation connecting blocks by welding.

Further, the upper end surfaces of the positioning plates support the vertical beams.

Further, the outer end surfaces of the side vertical plates cooperate with the inner end surfaces of the vertical beams.

Further, the upper end surface of each limiting block is provided with a flared inclined surface.

Further, a pry bar insertion hole is formed in the lower end surface of the supporting vertical plate assembly for separating the supporting vertical plate assembly from the positioning plates.

Beneficial Effects

One advantage of the utility model is that a lifting vertical plate is arranged between the two side vertical plates, and the lifting vertical plate is connected with the side vertical plates through isolation connecting blocks. By using isolation connecting blocks with different lengths, the fixture can adapt to different width dimensions. During positioning and welding, hammering may be required, and the arched surface and limiting sections of the lifting vertical plate can effectively lift and support the top plate of the reinforcing beam, thereby avoiding welding deformation.

Another advantage is that the utility model provides jackscrew plate assemblies and positioning plates for clamping the vertical beams. Meanwhile, limiting blocks are arranged at both ends of the side vertical plates, and the flared inclined surfaces on the upper ends of the limiting blocks facilitate insertion and positioning of the vertical beams.

Another advantage is that pry bar insertion holes are formed in the lower end surface of the supporting vertical plate assembly, which facilitates disassembly of the supporting vertical plate assembly from the positioning plates.

Specific Embodiment

The agricultural machinery steering axle reinforcing beam welding fixture includes an operating platform 1. Along the depth direction of the operating platform 1, a preset number of positioning plates 9 are arranged at equal intervals on the upper end surface of the operating platform 1. A supporting vertical plate assembly is inserted into the positioning plates 9.

The supporting vertical plate assembly includes two side vertical plates 6 and a lifting vertical plate 8 arranged between the two side vertical plates 6. The upper end surface of the supporting vertical plate assembly is provided with an arched surface 10 matched with the lower end surface of the top plate of the reinforcing beam. Limiting sections 12 matched with the top plate are arranged on both sides of the arched surface 10.

On the upper end surface of the operating platform 1, on both sides of the two side vertical plates 6, jackscrew plates 4 are arranged at equal intervals. Jackscrew bolts 5 are threaded through the jackscrew plates 4 in the horizontal direction, and the jackscrew bolts 5 cooperate with the outer end surfaces of the vertical beams.

Limiting blocks 2 are arranged at both ends of the side vertical plates 6, and the limiting blocks 2 cooperate with the front and rear end surfaces of the vertical beams.

Further, the lifting vertical plate 8 and the side vertical plates 6 are connected through isolation connecting blocks 7.

Further, the lifting vertical plate 8 and the side vertical plates 6 are connected with the isolation connecting blocks 7 by welding.

Further, the upper end surfaces of the positioning plates 9 support the vertical beams.

Further, the outer end surfaces of the side vertical plates 6 cooperate with the inner end surfaces of the vertical beams.

Further, the upper end surface of each limiting block 2 is provided with a flared inclined surface 3.

Further, a pry bar insertion hole 11 is formed in the lower end surface of the supporting vertical plate assembly for separating the supporting vertical plate assembly from the positioning plates 9.

During operation:

According to the actual condition of the workpiece, a suitable supporting vertical plate assembly is selected. The difference lies in the width and length of the isolation connecting blocks 7.

The selected supporting vertical plate assembly is inserted onto the positioning plates 9. Then, the pre-welded top plate of the reinforcing beam is placed on the upper end surface of the supporting vertical plate assembly. According to the actual condition of the workpiece, hammering may be performed so that the limiting sections 12 and the arched surface 10 correct the shape and structure of the top plate. The lower end surface of the top plate is matched with the arched surface 10, and both sides of the top plate are clamped by the limiting sections 12. In this way, both correction and positioning are achieved, solving the problem of poor welding caused by errors in the arched top plate.

The two vertical beams are inserted vertically into the flared inclined surfaces 3 on the upper ends of the limiting blocks 2, which facilitates insertion and positioning of the vertical beams.

Finally, the jackscrew bolts 5 are used to clamp the outer end surfaces of the vertical beams against the side vertical plates 6, thereby achieving clamping and correction of the top plate.

After welding, the jackscrew bolts 5 are loosened and the welded workpiece is removed. When the supporting vertical plate assembly needs to be replaced, a pry bar is inserted into the pry bar insertion hole 11 to separate the supporting vertical plate assembly from the positioning plates 9.
