Description

Technical Field

[0001] This utility model belongs to the field of vehicle frame manufacturing technology, and in particular relates to a bracket welding mold. Background Technology

[0002] The left bracket, right bracket, and wire channel are components of a bicycle or electric vehicle frame. When assembling them by spot welding, they need to be clamped and fixed separately. During clamping and fixing, it is necessary to ensure the position accuracy and firmness of the left bracket, right bracket, and wire channel to improve the quality of the product after spot welding. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a welding mold for left bracket, right bracket and wire groove with high positioning accuracy and fast clamping speed.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a bracket welding mold, including a base, an inner width and pin fixing seat, a contour fixing seat, a wire groove fixing block, fixing screws and positioning pins; the inner width and pin fixing seat and the contour fixing seat are all fixedly installed on the base, the wire groove fixing block is fixedly installed on the contour fixing seat, and a locking screw is screwed onto the wire groove fixing block. A quick clamp is fixedly installed on the top of the inner width and the pin fixing seat. A pressure plate is fixedly installed on the actuating end of the quick clamp. Two fixing screws are screwed on the left and right sides of the inner width and the pin fixing seat. The positioning pin is slidably installed inside the inner width and the pin fixing seat. An outer support contouring limit block is fixedly installed on the contouring fixing base.

[0005] Preferably, the bottom surface of the pressure plate is provided with a contoured groove.

[0006] As a preferred option, an inner support contouring limit block is also fixedly installed on the contouring fixing seat.

[0007] Preferably, the quick clamp has an elongated hole on its actuating end, and a screw is fixedly installed on the top of the pressure plate. The screw is locked in place in the elongated hole of the quick clamp by a lock nut.

[0008] Preferably, washers are fitted onto the fixing screws.

[0009] Compared with existing technologies, the advantages of this utility model are as follows: This welding mold positions and clamps the left support, right support, and wire channel before welding. The left and right supports are pressed and positioned on the inner width and pin fixing seat by fixing screws and positioning pins, ensuring that the corresponding first and second through holes on the left and right supports are coaxial. The inner and outer support contouring limit blocks work together to improve the positioning accuracy of the left and right supports on the contouring fixing seat. This improves the quality of the welded workpiece formed by the left support, right support, and wire channel. Attached Figure Description

[0018] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 7 The bracket welding mold shown includes a base 1, an inner width and pin fixing seat 2, a contour fixing seat 3, a wire groove fixing block 4, a fixing screw 6, and a positioning pin 7; the inner width and pin fixing seat 2 and the contour fixing seat 3 are both fixedly installed on the base 1, the wire groove fixing block 4 is fixedly installed on the contour fixing seat 3, and a locking screw is screwed onto the wire groove fixing block 4. A quick clamp 21 is fixedly installed on the top of the inner width and pin fixing seat 2. A pressure plate 22 is fixedly installed on the execution end of the quick clamp 21. Two fixing screws 6 are screwed on the left and right sides of the inner width and pin fixing seat 2. The positioning pin 7 is slidably installed inside the inner width and pin fixing seat 2. An outer support contouring limit block 5 is fixedly installed on the contouring fixing base 3.

[0019] The bottom surface of the pressure plate 22 is provided with a contoured slot 23, which increases the fit with the left bracket 8 and the right bracket 9, and makes the left bracket 8 and the right bracket 9 more firmly pressed and positioned.

[0020] The contouring fixing base 3 is also fixedly provided with an inner support contouring limiting block 51. The inner support contouring limiting block 51 and the outer support contouring limiting block 5 work together to limit and position the inner and outer surfaces of the left support 8 and the right support 9, thereby improving the positioning accuracy of the left support 8 and the right support 9 on the contouring fixing base 3.

[0021] The quick clamp 21 has an elongated hole 210 on its actuating end. A screw 221 is fixedly installed on the top of the pressure plate 22. The screw 221 is locked in the elongated hole 210 of the quick clamp 21 by a lock nut. After loosening the lock nut, the position of the screw 221 and the pressure plate 22 assembly can be adjusted.

[0022] A washer 61 is fitted onto the fixing screw 6, and the washer 61 can fix the screw 6 and prevent it from loosening.

[0023] Lift the quick clamp 21 upwards, first clamping the left bracket 8 and right bracket 9. Place the left bracket 8 and right bracket 9 on the contour fixing seat 3. The inner and outer bracket contour limiting blocks 51 and 51 work together to restrict and position the inner and outer surfaces of the left bracket 8 and right bracket 9. Positioning pins 7 pass through the second through holes 82 and 92 and are installed within the inner width and pin fixing seat 2 to axially position the two. Then, two fixing screws 6 pass through the first through holes 81 and 91 and are screwed onto the inner width and pin fixing seat 2 to press and position the two. Secure the wire groove 10 to the wire groove fixing block 4 using the locking screws. The operator then performs spot welding on the joint area of ​​the left bracket 8, right bracket 9, and wire groove 10.
