Description

Technical Field

[0001] This utility model relates to the field of welding technology, and more specifically, to a welding fixture that can be quickly replaced. Background Technology

[0002] Reference Figure 9 Some welding workpieces require two contact blades 31 to be welded to the bottom of the cap body. The fixture used for welding these workpieces typically needs a side positioning mechanism, which is usually fixed to the welding machine along with the fixture body. Since welding requires placing the two contact blades and the cap body into the positioning slots of the fixture, the time required to place the cap body and contact blades increases with the number of positioning slots. This results in the time required to assemble the cap body and contact blades onto the welding fixture being much longer than the welding time of the welding machine, leading to low welding efficiency. Adding multiple welding machines not only occupies a large space but also increases the cost of the welding machines, which is detrimental to production. Utility Model Content

[0003] This utility model discloses a welding fixture that can be quickly replaced, aiming to improve the problem of low welding efficiency and production disadvantage of existing welding fixtures.

[0004] The present invention adopts the following solution:

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model.

[0032] Example

[0033] Combination Figures 1 to 10 This embodiment provides a quick-change welding fixture, including a fixture body 1 and a lateral positioning mechanism 2 adapted and connected to the fixture body 1. The fixture body 1 is provided with a positioning groove 11 for assembling a workpiece 3 to be welded, and a moving channel 12 communicating with the positioning groove 11. The lateral positioning mechanism 2 is arranged opposite to the moving channel 12 and includes a positioning block 21 and an elastic member 22 abutting between the positioning block 21 and the fixture body 1. The welding fixture is configured to engage with a second guide portion on the welding machine table via a first guide portion 13 on both sides of the fixture body 1, so as to move along the second guide portion to the welding position. Under the action of the driving member of the welding machine table, the limiting portion 211 on the positioning block 21 extends along the moving channel 12 and abuts against the workpiece 3 to be welded.

[0034] For example, a second guide portion is provided on both sides of the fixture body 1 on the welding machine platform. The second guide portion is configured as a guide groove, and the first guide portion 13 on the fixture body 1 is configured as a guide rail. A stop post is provided on the welding machine platform. During assembly, the guide rail on the fixture body 1 is slid into the guide groove and then moved to abut against the stop post, so that the welding fixture is positioned for welding. Then, the driving component is driven to abut against the positioning block 21, which in turn causes the positioning block 21 to abut against the elastic component 22 and compress. The limiting portion 211 extends along the moving channel 12 and abuts against the workpiece 3 to be welded, thereby achieving lateral positioning of the workpiece 3 to be welded. Finally, the welding operation can be performed. After welding is completed, the guide rail is slid out along the guide groove, and the next welding fixture can be slid into the guide groove for welding. This process is repeated, allowing the welding machine platform to perform welding operations continuously.

[0035] It should be noted that in this embodiment, by providing a first guide portion 13 adapted to the welding machine on the fixture body 1, the fixture body 1 can move along the second guide portion to the welding position, thereby achieving rapid replacement of the welding fixture. It is easy to understand that multiple welding fixtures can be set up. After the workpiece 3 to be welded is assembled on the welding fixture at other workstations, it is then transferred to the welding workstation. The operator at the welding workstation moves the fixture body 1 to the welding position to perform the welding operation. This shortens the waiting time of the welding machine, ensures continuous operation of the welding machine, and thus improves welding efficiency. Compared with adding a welding machine, adding replaceable welding fixtures is much cheaper and occupies less space, which is more conducive to production. In addition, the drive component only needs to abut against the positioning block 21 and does not need to cooperate with the welding fixture, which can reduce the fitting accuracy and ensure stable welding quality.

[0036] In a preferred embodiment, the lateral positioning mechanism 2 further includes a stop block 23 and a guide rod 24 fixedly connected to the fixture body 1. The stop block 23 is provided with a limiting hole 231 connected to the moving channel 12. The positioning block 21 is sleeved on the guide rod 24, with one end located outside the stop block 23 and the limiting part 211 of the other end passing through the limiting hole 231. An elastic element 22 is sleeved on the guide rod 24 and abuts against the positioning block 21. The elastic element 22 is preferably a spring, and the driving component on the welding machine is a cylinder. The cylinder abuts against the positioning block 21 to move the positioning block 21 along the guide rod 24 and compress the spring, thereby pressing against the workpiece 3 to be welded. After welding is completed, the cylinder retracts, and the positioning block 21 resets under the elastic action of the spring, facilitating the removal of the welded workpiece 3. Further, the positioning block 21 is T-shaped, with its horizontal section 212 sleeved on the guide rod 24 and its vertical section forming the limiting part 211. There are two guide rods 24, and the horizontal section 212 is symmetrically equipped with mounting holes for fitting the guide rods 24 so that the force on the positioning block 21 is balanced.

[0037] Based on the above embodiments, in an optional embodiment of this utility model, the fixture body 1 includes an upper seat 14 and a lower seat 15. A positioning groove 11 is formed in the upper seat 14, and the lower seat 15 is detachably connected to the upper seat 14. The lower seat 15 protrudes from the upper seat 14 on both sides to form a first guide portion 13. When welding different products, only the upper seat 14 needs to be replaced, further reducing the cost of the welding fixture. The upper seat 14 and the lower seat 15 can be fixed together with screws. For example, a relief groove 151 is recessed along the middle of the first guide portion 13 to reduce the contact area when the first guide portion 13 engages with the second guide portion, thereby reducing the resistance of the fixture body 1 when moving along the second guide portion. Furthermore, the bottom surface of the lower seat 15 is provided with crisscrossing grooves 152 to prevent the lower seat 15 from adhering to the workbench surface during circulation, reducing the moving resistance of the lower seat 15.

[0038] In other embodiments, two positioning grooves 11 are symmetrically arranged on the upper seat 14, and a cavity 141 is recessed between the two positioning grooves 11. The opening of the cavity 141 faces the lower seat 15 to reduce the overall weight of the welding fixture and facilitate its movement on the worktable. The fact that the opening of the cavity 141 faces the lower seat 15 helps prevent dirt and grime from accumulating. Preferably, the inlet of the positioning groove 11 is chamfered 111 to facilitate the discharge of welding dust and ensure welding quality.

[0039] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
