Description

Technical Field

[0001] This utility model relates to the field of welding positioning, specifically to a positioning fixture for capacitor welding. Background Technology

[0002] After the capacitor is filled with electrolyte through the eccentric injection hole, the injection hole needs to be sealed using welding equipment. Currently, the position of the injection hole is uncertain after each capacitor placement, requiring welding equipment to identify and locate the hole before welding. This identification and positioning system is relatively expensive. Therefore, this patent attempts to find an alternative solution. Utility Model Content

[0003] The present invention aims to provide a positioning fixture for capacitor welding, so as to position the eccentric injection hole of the capacitor to the same position before welding, so that the welding equipment can weld at the same position each time.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a positioning fixture for capacitor welding, comprising a support member, a lifting mechanism, a positioning mechanism, and a clamping mechanism. The clamping mechanism includes a first clamp and a second clamp capable of clamping the capacitor. The lifting mechanism includes a gear and a toothed column. The toothed column is slidably connected to the support member, the gear is rotatably connected to the support member, and the gear meshes with the toothed column. The positioning mechanism is connected to the toothed column and includes a positioning element. The positioning element is located above the capacitor and is used to position the eccentric injection hole.

[0005] The technical effect of this solution is as follows: After the capacitor is placed in the clamping mechanism, the rotating gear drives the toothed column to move downward, thereby causing the positioning component of the positioning mechanism to contact the capacitor. Then, the position of the capacitor is adjusted so that the positioning component is aligned with the liquid injection eccentric hole of the capacitor. After the capacitor is clamped by the first and second clamps, the liquid injection eccentric hole can be welded and sealed. Since the liquid injection eccentric hole is positioned before welding, the welding equipment can weld at the same position each time.

[0006] Preferably, as an improvement, it also includes a base, and the support includes a support column and a support frame. The support column is fixedly connected to the base and the support frame, the gear column is slidably connected to the support frame, and a fixed column is rotatably provided on the support frame. The gear is located inside the support frame and is keyed to the fixed column.

[0007] Preferably, as an improvement, the lifting mechanism further includes a pressure rod, which is located outside the support frame and fixedly connected to the fixed column.

[0008] Preferably, as an improvement, the positioning element includes a positioning block, a positioning tube, a positioning post, and a spring. The positioning block is connected to the toothed post, the positioning tube is fixedly connected to the positioning block, and the positioning post is slidably connected to the positioning tube via the spring.

[0009] The technical effect of this solution is that after the positioning post contacts the capacitor, the position is adjusted by rotating the capacitor. When the positioning post is aligned with the injection eccentric hole, the positioning post springs into the injection eccentric hole under the action of the spring, which helps to improve the positioning accuracy of the injection eccentric hole.

[0010] Preferably, as an improvement, the positioning mechanism also includes a dial, which is connected to the toothed column, and the positioning block is slidably connected to the dial.

[0011] Preferably, as an improvement, the clamping mechanism further includes a screw and a nut, the first clamp is provided with a through hole, the screw is fixedly connected to the second clamp, and the screw can pass through the through hole to connect with the nut.

[0012] Preferably, as an improvement, both the first and second clamps are provided with two clamping positions, and the number of positioning elements is also two, with each positioning element located on a dial on one side of the toothed column. Attached Figure Description

[0017] The following detailed description illustrates the specific implementation method:

[0018] The reference numerals in the accompanying drawings include: base 1, first clamp 2, second clamp 3, support column 4, support frame 5, gear 6, tooth column 7, pressure rod 8, dial 9, positioning block 10, positioning tube 11, and positioning column 12.

[0019] The basic implementation examples are as follows: Figure 1-4 As shown: Figure 1The illustrated positioning fixture for capacitor welding includes a base 1, a support, a lifting mechanism, a positioning mechanism, and a clamping mechanism. The clamping mechanism includes a first clamp 2 and a second clamp 3, each with two arc-shaped clamping positions. When the first clamp 2 and the second clamp 3 are closed, they clamp the capacitor. Specifically, the first clamp 2 is bolted to the base 1 and has a through hole. A screw is welded to the second clamp 3, passing through the through hole and connecting to a nut, thereby locking the first clamp 2 and the second clamp 3.

[0020] The support includes a support column 4 and a support frame 5. A support seat is bolted to the base 1. The support column 4 is inserted into the support seat and fixed thereto. One end of the support frame 5 has a sliding hole, and the other end of the support frame 5 is open and has a connecting hole. A threaded hole is opened at the open position of the support frame 5. The support column 4 passes through the connecting hole. After the bolt is screwed into the threaded hole, the support frame 5 and the support column 4 are fixed.

[0021] like Figure 2 As shown, the lifting mechanism includes a gear 6, a toothed column 7, and a lowering rod 8. The toothed column 7 is slidably connected to the sliding hole of the support frame 5. The front side of the support frame 5 is provided with a stepped hole, and a ring is bolted to the stepped hole. A fixed column is rotatably installed on the rear side of the support frame 5 and on the ring. The gear 6 is located inside the support frame 5 and is keyed to the fixed column. The gear 6 meshes with the toothed column 7. The lowering rod 8 is located outside the support frame 5. The lowering rod 8 is welded to the fixed rod or passes through the fixed column and is interference-fitted. Of course, the part of the fixed column outside the support frame 5 can also be set as a flat opening, with a sleeve on the flat opening. The lowering rod 8 passes through the sleeve and the fixed column and is interference-fitted, which facilitates the rotation of the gear 6.

[0022] like Figure 3 As shown, the positioning mechanism includes a dial 9 and two positioning components. The lower end of the gear post 7 is inserted into the middle of the dial 9 and fixedly connected. The dial 9 has graduations. The two positioning components are each located on one side of the dial 9 of the gear post 7, specifically as follows... Figure 3 , 4 As shown, the positioning component includes a positioning block 10, a positioning tube 11, a positioning post 12, and a spring. The positioning block 10 is slidably connected to the dial 9, and the positioning block 10 can be locked to the dial 9 by bolts, which can adjust the position of the positioning component. The positioning tube 11 passes through the positioning block 10 and is interference-fitted with the positioning block 10. The positioning post 12 is slidably connected to the positioning tube 11 by the spring. Specifically, the lower end of the spring is welded to the positioning post 12. The upper end of the positioning tube 11 is provided with a spiral groove. The upper end of the spring is fixed by being inserted into the spiral groove or by welding. The positioning post 12 is located above the capacitor and can extend into the liquid injection eccentric hole for positioning.
