Technical Field

[0001] This utility model relates to the field of side plate welding technology, specifically to a tooling for welding connector side plates. Background Technology

[0002] The connector side plate is the core structural component of the connector. It is mainly used to protect internal components, strengthen overall rigidity and ensure assembly accuracy. The connector side plate module is usually composed of three thick plates (δ≥30mm) forming an arc weld bead. It requires senior welders to perform multi-layer and multi-pass welding. Appropriate welding tooling is required during the welding process. In the existing technology, the existing side plate welding fixture uses a clamping structure and positioning groove to clamp and fix the side plate. Although it can keep the side plate stable, the existing welding fixture is difficult to fix side plates of different sizes due to the difference in side plate size. The adaptability is too low. When the side plate is changed, the fixture needs to be replaced, which increases production costs and downtime. Utility Model Content

[0022] like Figures 1-4 As shown, it illustrates a connector side plate welding fixture in one embodiment of the present invention, applied to side plate 1. Side plate 1 is welded from three thick plates. Two positioning holes 2 are provided on side plate 1. The two positioning holes 2 are on the same vertical line and are respectively located on the upper and lower sides of one end of side plate 1. It should be noted that the distance between the two positioning holes 2 on side plates 1 of different sizes is different. It includes a base plate 3, a central positioning tube 4, a rotating mechanism, a support 5, and a fixing component. like Figure 1 and Figure 2As shown, the central positioning tube 4 is rotatably set at the center of the base plate 3. The rotating mechanism is set on the base plate 3 to drive the central positioning tube 4 to rotate. The base plate 3 can be fixed in the use position by fixing screws for easy disassembly. The rotating mechanism includes a gear 7, a rack 8 and a drive assembly. The gear 7 is rotatably set in the base plate 3. A rotating groove is opened on the base plate 3. The gear 7 is fitted on the central positioning tube 4 and is coaxially fixedly connected to the central positioning tube 4. A sliding groove 9 is opened in the base plate 3. The rotating groove and the sliding groove 9 are connected. The rack 8 is slidably set in the sliding groove 9 and meshes with the gear 7. In order to provide sufficient movement space for the rack 8, the sum of the length of the groove 11 and the length of the rack 8 is the length of the sliding groove 9. The drive assembly is mounted on the base plate 3 and is used to drive the rack 8 to move along the inner wall of the slide groove 9. The drive assembly includes a drive plate 10 and an electric cylinder 12. A slot 11 is provided on the base plate 3 and the slot 11 communicates with the slide groove 9. The drive plate 10 is fixedly connected to one end of the rack 8 and slides in cooperation with the inner wall of the slot 11. The electric cylinder 12 is mounted on the base plate 3 and the output end of the electric cylinder 12 is fixedly connected to one end of the drive plate 10. By starting the electric cylinder 12, the output end of the electric cylinder 12 pushes the drive plate 10 to move along the inner wall of the slot 11. The drive plate 10 drives the rack 8 to move along the inner wall of the slide groove 9. The rack 8 drives the gear 7 to rotate. The rotation of the gear 7 drives the central positioning tube 4 to rotate. like Figure 3 and Figure 4 As shown, two supports 5 are symmetrically fixed on the central positioning tube 4. In order to keep the supports 5 stable on the central positioning tube 4, the central positioning tube 4 is driven to rotate by the electric cylinder 12. The central positioning tube 4 drives the two supports 5 to rotate. It should be added that the base plate 3 is fixed in the working position. A welding device (welding robot) is set on one side of the base plate 3. The welding robot welds multiple thick plates into side plates 1. The welding robot is usually fixed on one side of the central positioning tube 4. The two supports 5 are rotated 180 degrees by the central positioning tube 4. After one side plate 1 is welded, the other side plate 1 to be welded can be rotated to the welding station of the welding robot. Both supports 5 are fixedly connected to the central positioning tube 4 by multiple reinforcing plates 19. The supports 5 are provided with fixing holes 6 that cooperate with the side plates 1. The fixing holes 6 are used to cooperate with the positioning holes 2 at the bottom of the side plates 1. A fixing assembly is installed on the support 5 to detachably fix the side plate 1 and for subsequent welding. The fixing assembly includes a distance adjustment groove 13, a fixing plate 14, and fastening bolts 16. The support 5 has a distance adjustment groove 13, and the fixing plate 14 is fixedly connected to the support 5. The fixing plate 14 has multiple through holes 15, all of which communicate with the distance adjustment groove 13. The side plate 1, the fixing plate 14, and the support 5 are all detachably connected by two fastening bolts 16. First, a fastening bolt 16 is used to fix the bottom end of the side plate 1 to the support 5 through the positioning hole 2 and the fixing hole 6 at the bottom end of the side plate 1. It should be noted that before fixing, the axis of the positioning hole 2 at the other end of the side plate 1 and the axis of the through hole 15 must be kept on the same vertical plane so that the support 5 can be fixed by the fastening bolts 16. The fixed plate 14 and the side plate 1 are firmly fixed and mechanically locked. The fastening bolt 16 includes a nut 17 and a screw 18. The screw 18 can pass through the distance adjustment groove 13. The diameter of the nut 17 is larger than the width of the distance adjustment groove 13. In order to allow the screw 18 to pass through the positioning hole 2, the through hole 15 and the fixing hole 6, the diameters of the through hole 15, the fixing hole 6 and the positioning hole 2 are the same and all larger than the diameter of the screw 18. According to the different sizes of the side plate 1, after the bottom end of the side plate 1 is fixed to the support 5 by the fastening bolt 16, the positioning hole 2 at the other end of the side plate 1 is connected to one of the through holes 15. Then, another fastening bolt 16 is used to fix the other end (top) of the side plate 1 to the support 5. In this way, the side plate 1 is kept stable. And by providing multiple through holes 15 in the longitudinal direction, side plates 1 of different sizes can be fixed. Working principle: During the process of fixing the side plate 1, the tooling for welding the connector side plate uses screws to fix the base plate 3 to the welding station. The positioning hole 2 at the bottom of the side plate 1 is connected to the fixing hole 6, and the axis of the positioning hole 2 at the other end of the side plate 1 is kept on the same vertical plane as the axis of the through hole 15. At this time, the two positioning holes 2 on the side plate 1 are connected to the fixing hole 6 and the through hole 15 respectively. Two fastening bolts 16 are used to lock and fix the side plate 1 to the support 5 and the fixing plate 14. With multiple through holes 15 arranged longitudinally, side plates 1 of different sizes can be fixed, providing good adaptability. The electric cylinder 12 is activated to push the drive plate 10 to remain stable. The side plates 1 (three thick plates) on one side of the central positioning tube 4 are welded using welding equipment. Then, the electric cylinder 12 is activated, and the output end of the electric cylinder 12 pushes the drive plate 10 to move along the inner wall of the slot 11. The drive plate 10 drives the rack 8 to move along the inner wall of the slide 9. The rack 8 drives the gear 7 to rotate. The rotation of the gear 7 drives the central positioning tube 4 to rotate 180 degrees. After one side plate 1 is welded, the other side plate 1 to be welded can be rotated to the welding position of the welding equipment, which is convenient to operate and can improve welding efficiency.
