Description

Technical Field

[0001] The utility model belongs to the technical field of wheel rim processing auxiliary equipment and relates to a clamping tool for a connecting buckle. Background Art

[0002] In large-sized rims, due to usage requirements, it is necessary to add a connecting buckle on the inner ring surface of the rim to connect it with the bolts of the spoke plate. The connecting buckle needs to be welded inside the rim, and the welding position and positioning method of the connecting buckle are directly related to the quality of the product, so a clamping tool needs to be designed. For the structure and working principle of the clamping tool, please refer to a rim connecting buckle welding device provided by application number 202223315900.4.

[0003] Generally, the fixture used is a backing type, with the connector directly placed on the backing surface, pressed by one hand and spot welded with the other hand. After all the connectors are spot welded in sequence, they are taken out and welded again. The disadvantage of this method is that during the welding process of the connector, the manual pressing and positioning is inaccurate, the operation is inconvenient, and the efficiency is low, resulting in unstable product quality. Summary of the invention

[0004] The utility model aims at the above problems existing in the prior art and provides a clamping tool for a connecting buckle. The technical problem to be solved by the utility model is: how to improve the convenience of operation.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0007] Its working principle is: when in use, first place the rim on the mounting seat, and after fixing the rim, place the connecting buckle on the positioning block. The driving part drives the guide rod to move toward the positioning block, so that the clamping part on the guide rod presses the connecting buckle, and then welds the corresponding positions between the connecting buckle and the rim. After welding is completed, take out the product and this process is completed.

[0008] The clamping tool can greatly improve the convenience of operation. The guide block plays a good guiding role on the guide rod, improves the stability during movement, and enables the clamping piece to clamp the connecting buckle more accurately.

[0009] In the above-mentioned clamping tool of the connecting buckle, the clamping member includes a fixed block and a pressing block 1, the fixed block is installed on the outer end of the guide rod, and a spring 1 is connected between the pressing block 1 and the fixed block.

[0010] The pressure block 1 is connected to the fixed block through a spring 1. The spring 1 can enable the pressure block 1 to elastically clamp the connecting buckle to prevent some connecting buckles from being unclamped due to errors of the connecting buckle, thereby ensuring the welding quality.

[0011] In the above-mentioned clamping fixture of the connecting buckle, a second pressing block is arranged on the top of the first pressing block, the outer end of the first pressing block has a groove, and the second pressing block extends from above the groove.

[0012] After the first pressure block presses the connecting buckle, part of the connecting buckle is located in the groove, which effectively prevents the connecting buckle from falling off. After the first pressure block presses the connecting buckle in the horizontal direction, the second pressure block presses the connecting buckle in the vertical direction. This structure can prevent the connecting buckle from warping and improve the welding quality.

[0013] In the above-mentioned clamping tool of a connecting buckle, a pressure rod is also provided on the top of the pressure block 1, and the upper part of the pressure rod has a convex edge.

The spring 2 is located between the convex edge and the pressure block 2 and is in a compressed state.

[0014] The second pressure block can move up and down along the pressure rod. The second spring on the pressure rod has a downward elastic force on the second pressure block, so that after the second pressure block abuts against the connecting buckle, the second pressure block elastically presses the connecting buckle. This structure can press the connecting buckles at different heights and has good adaptability.

[0015] In the above-mentioned clamping tool of a connecting buckle, the driving part includes a cylinder one, and a pressure block three is installed on the piston rod of the cylinder one, and the width of the pressure block three gradually decreases from top to bottom. A tensioning block is provided at the inner end of the guide rod, and the tensioning block has an inclined surface, and the inclined surface gradually inclines from top to bottom toward the direction approaching the pressure block three, and the pressure block three can be abutted against the inclined surface of the tensioning block.

[0016] When the cylinder drives the pressing block three to move downward, the pressing block three abuts against the inclined surface of the tensioning block to push the tensioning block to move outward, so that the guide rod moves toward the positioning block, and the pressing piece on the guide rod presses the connecting buckle.

[0017] In the above-mentioned clamping tool of a connecting buckle, the cylinder one is installed in the middle of the mounting seat, the positioning blocks are more than two and are distributed along the circumference of the mounting seat, the guide rods are also more than two and are distributed along the circumference of the mounting seat, each guide rod corresponds to a positioning block respectively, and a tensioning block is provided at the inner end of each guide rod, the tensioning block has an inclined surface, and the inclined surface gradually inclines from top to bottom toward the direction approaching the pressure block three, the tensioning blocks are distributed along the circumference of the pressure block three, and the pressure block three can be abutted against the inclined surfaces of each tensioning block.

[0018] There are more than two positioning blocks, a connecting buckle is placed on each positioning block, and there are more than two guide rods. When cylinder one drives pressure block three to move downward, pressure block three abuts against the inclined surfaces of each tensioning block, and then pressure block three simultaneously pushes each tensioning block to move outward, so that each guide rod simultaneously moves toward the corresponding positioning block, so that the clamping parts on each guide rod respectively clamp the corresponding connecting buckles. This structure can clamp multiple connecting buckles synchronously, greatly improving the convenience of operation and work efficiency.

[0019] In the above-mentioned clamping tool for a connecting buckle, the bottom of the mounting seat has a receiving groove, and the cylinder 1 is arranged in the receiving groove.

[0020] The structure hides the cylinder 1 in the wheel rim positioning plate, so that the cylinder 1 does not occupy extra space, and the entire tooling structure is compact and more beautiful.

[0021] In the above-mentioned clamping tool for the connecting buckle, the mounting seat includes a rim positioning plate and a connecting buckle positioning plate, and a gasket is arranged between the rim positioning plate and the connecting buckle positioning plate.

[0033] like Figure 4 As shown, when in use, first place the rim 22 on the mounting seat 1, and after fixing the rim 22, place the connecting buckle 23 on the positioning block 2, and the driving member 5 drives the guide rod 3 to move toward the positioning block 2, so that the clamping member 4 on the guide rod 3 clamps the connecting buckle 23, and then welds the corresponding positions between the connecting buckle 23 and the rim 22. After welding is completed, take out the product and this process is completed.

[0034] The clamping tool can improve the convenience of operation. The guide block 6 plays a good guiding role on the guide rod 3, improves the stability during movement, and enables the clamping member 4 to clamp the connecting buckle 23 more accurately.
