Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, and particularly relates to a light sidecar welding tooling. Background Art

[0002] The frame structure of a sidecar mainly includes a two-wheel frame and a sidecar frame which are connected to each other. For the assembly and manufacturing of a sidecar, it is first necessary to ensure the stability of frame production. Currently, the production of the two-wheel frame and the sidecar frame is usually carried out independently, and then transported together for overall welding and processing. Since the frames are mostly pipe fittings, the thermal expansion and contraction effects after welding and the bumps during the transportation process will affect the shape errors of the two-wheel frame and the sidecar frame, which is likely to cause subsequent assembly errors. For example, the assembly error between the two-wheel frame and the sidecar frame increases, and large welding gaps are prone to false welding, directly affecting the product quality. Summary of the Invention

At one side of the upper end surface edge of each second support block 13, a baffle 131 is provided. A through groove 220 is formed by enclosing between the convex platform 22 at the corresponding position and the baffle 131.

[0031] Among them, a guide groove 132 is vertically provided on the inner side wall of each second support block 13. At the position of the guide groove 132 corresponding to the convex platform 22 at the corresponding position, a guide block 221 is provided.

[0033] Similarly, at the position of the second frame platform 12 corresponding to the second support block 13, a plurality of positioning brackets 4 are symmetrically arranged on the left and right along the length direction of the support plate 2, and a positioning block 40 extending upward is provided on each of the positioning brackets 4, and a second pressing block 41 is hingedly provided on the positioning block 40, and a bending section 42 extending perpendicularly to the second pressing block 41 is provided at the non-hinged end of the second pressing block 41, and the end face of the extending end of the bending section 42 is in contact with the upper end face of the positioning bracket 4, and the inner side wall of the bending section 42 and the inner side wall of the positioning block 40 are surrounded to form a positioning hole 43 connected to the through groove 220; a second limiting hole 411 for a clamping bolt 44 to pass through is provided on the second pressing block 41, and a threaded hole is provided at the position of the positioning block 40 corresponding to the second limiting hole 411, and the protruding end of the clamping bolt 44 is screwed to the threaded hole, and the lower end face of the nut of the clamping bolt 44 abuts against the upper end face of the second pressing block 41.

[0034] The connecting pipe bracket 10 is fixed on the first frame platform 11 , and a horizontally extending fixing block 101 is provided on the connecting pipe bracket 10 at a position corresponding to a gap formed between two adjacent second supporting blocks 13 , and a limiting groove 102 is provided on the fixing block 101 .

[0035] A connecting bracket 3 is provided on the second frame platform 12 near the connection position between the second frame platform 12 and the support plate 2. The upper end surface of the connecting bracket 3 is flush with the upper end surface of the positioning bracket 4 to prevent the side bucket frame from falling during movement.

[0036] The use principle of the present invention is as follows:

[0037] like Figures 1 to 3 As shown, the two-wheeled frame includes a left pipe and a right pipe. Before use, five first support blocks 110 are placed on the left and right sides of the first frame platform 11, and the positioning grooves 14 on the five first support blocks 110 are connected to the pipes on the corresponding sides; when in use, the stand pipe on the two-wheeled frame is sleeved on the outer side of the limiting support rod 112, and then the left pipe and the right pipe are placed in the positioning grooves 14 on the first support blocks 110 on the corresponding sides, and the hinged first pressing block 15 is turned over, so that the positioning groove 152 and the positioning groove 14 are surrounded to form a through hole 150 for placing the pipe of the two-wheeled frame; the locking bolt 16 passes through the first limiting hole 151 and is screwed to the threaded hole on the first support block 110, and the lower end surface of the nut of the locking bolt 16 abuts against the upper end surface of the first pressing block 15, fixing the left and right pipes of the two-wheeled frame, so that the stand pipe and the pipe of the two-wheeled frame are positioned and welded.

[0038] At the same time, if Figure 1 and Figure 5As shown, turn on the linear motor 20 to drive the boss 22 to move upward. The guide block 221 slides synchronously in the guide groove 132. The upward-moving boss 22 and the baffle 131 enclose a through groove 220. Place the two frame pipe fittings on the left and right sides of the side bucket at the positions of the through groove 220 on the corresponding sides. Then place the two ends of the connecting pipe fitting between the frame pipe fittings ( Figure 5 in the state shown by the upper dotted line in the middle) in the two placement grooves 222 symmetrically arranged on the left and right along the length direction of the support plate 2. At this time, only need to perform pre-welding connection at the upper end position of the connection between the connecting pipe fitting and the frame pipe fitting, and make the connecting pipe fitting and the frame pipe fitting jointly form a side bucket frame. It should be noted that since the range of pre-welding is not large, the heat accumulated on the pipe fittings is not much, and it is multi-point pre-welding. The axial thermal deformation interferes with each other, and the deformation rate is not large, and it is not easy to cause the situation of thermal arching. Just ensure that the pipe fittings do not expand and deform horizontally outward.

[0039] Subsequently, as Figure 1 , Figure 4 and Figure 5 shown, turn on the linear motor 20 again to drive the boss 22 to move downward, expose the lower end position of the connecting pipe fitting, then loosen the compression bolt 44, flip the second pressing block 41, and synchronously drive the bent section 42 to move to the outer position of the positioning bracket 4. Immediately, horizontally push the pre-welded side bucket frame. During this process, it is assisted by the connecting support frame 3. After the side bucket frame completely moves to the positioning bracket 4, flip the second pressing block 41. The end face of the protruding end of the bent section 42 fits against the upper end face of the positioning bracket 4, and the inner side wall of the bent section 42 and the inner side wall of the positioning block 40 enclose a positioning groove 43 communicated with the through groove 220. The compression bolt 44 passes through the second limiting hole 411 and is screwed into the threaded hole on the positioning block 40, and the lower end face of the nut of the compression bolt 44 abuts against the upper end face of the second pressing block 41 to fix the frame pipe fittings of the side bucket.

[0040] At this time, place a connecting pipe (not marked) at the position of the limiting groove 102, and spot-weld the two ends of the connecting pipe to the frame pipe fittings of the two-wheel vehicle frame and the side bucket frame respectively. Finally, complete the welding of the lower end of the pre-welded position of the side bucket frame, and then complete the welding of the spot-welded position of the connecting pipe. After welding, first loosen the locking bolt 16, flip the first pressing block 15 to expose the upper space of the two-wheel vehicle frame, then loosen the compression bolt 44, flip the second pressing block 41, and synchronously drive the bent section 42 to move to the outer position of the positioning bracket 4 to expose the upper space of the side bucket frame. Pull out the inserted limiting support rod 112, and then lift the welded vehicle frame as a whole.

[0041] It should be noted that while the two-wheel frame and the side car frame are integrally welded, according to the aforementioned related operation content, the pre-welding operation of the next side car frame can be carried out on the support plate 2 at the same time. In this way, after the integral frame is taken out after welding, the next pre-welded side car frame is directly moved to the second frame table 12. After the two-wheel frame is welded, the connecting pipe is put in for integral welding. At the same time, the side car frame is pre-welded on the support plate 2 again. By repeating such operations, the transfer cycle of parts is reduced and the production efficiency is improved.

[0042] It should be noted that the position where the positioning bracket 4 supports the side car frame is staggered from the pre-welding position, so that the lower part of the pre-welding position can be exposed, which is convenient for completing all welding operations at this position.

[0043] In addition, on the first frame table 11, in addition to the left and right pipe fittings of the two-wheel frame, there are other pipe fittings welded. This embodiment mainly protects the operation settings at the welded connection position between the two-wheel frame and the side car frame. On the premise of not affecting the removal of the two-wheel frame, the welding settings of other pipe fittings are the same as those in the prior art and will not be elaborated here.
