Description

Technical Field

[0001] The utility model relates to a welding fixture, in particular to a battery tray welding fixture, belonging to the technical field of welding fixtures. Background Art

[0002] The welding process of the battery tray includes clamping, tip alignment, preheating, determining the welding sequence, unloading, interval protection welding, cooling, cleaning and other steps. Although the battery tray has basically achieved semi-automatic or automatic welding in the production process, in the automatic or semi-automatic welding process, due to differences in equipment accuracy and operator skill level, uneven welding or defects may occur. Manual repair welding can ensure the welding quality and avoid potential safety hazards. The design of the battery tray may include complex structures and special requirements. Automatic welding equipment may find it difficult to fully adapt to these requirements. Manual repair welding can better meet the design requirements. In the welding process, some defects that are difficult to detect by equipment may occur. Manual repair welding can detect and repair these defects in time to ensure the overall quality of the product. In summary, although automated welding equipment can improve production efficiency and welding quality, manual repair welding is still an indispensable link in the production process of the battery tray to ensure the quality and safety of the final product. In the process of manual repair welding, in order to prevent the battery tray from moving, the tray is generally clamped and fixed by a fixture.

[0003] However, due to the large size of the battery tray, the traditional clamp requires the worker to hold the welding tool and constantly change the position to weld different positions of the battery tray after clamping the battery tray. This process requires the worker to move over a large range, which wastes time and physical strength, thereby reducing the efficiency of welding. Utility Model Content

[0004] The purpose of the present utility model is to provide a battery tray welding fixture in order to solve the above problems. After the battery tray is clamped and fixed, the orientation of the battery tray can be flexibly adjusted, thereby avoiding the need for workers to move over a larger range to weld different parts of the battery tray, thereby effectively improving the welding efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] As a technical optimization solution of the utility model, Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the fixed structure 7 includes an electric push rod 701 and a sliding rod 702, the connecting rod 6 is slidably connected to the sliding rod 702, the sliding rod 702 is fixedly connected to the push sleeve 703, the turntable 8 is slidably connected to a push piece 704, one end of the push piece 704 is in contact with the push sleeve 703, and the other end of the push piece 704 is in contact with the support seat 1, two guide columns 707 are fixedly connected to the connecting seat 2, and the two guide columns 707 are slidably connected to the same push plate 708, the sliding rod 702 is slidably connected to a push block 705, and the push block 705 A spring 706 is provided on the outer sleeve, one end of the spring 706 abuts against the slide bar 702, and the other end of the spring 706 abuts against the block 705. One side of the abutment plate 708 abuts against the connecting plate 9, and the other side of the abutment plate 708 abuts against the block 705. An electric push rod 701 is installed on the connecting rod 6, and the extended end of the electric push rod 701 is fixedly connected to the slide bar 702. The cross-section of the bottom end of the slide bar 702 is L-shaped, and the cross-section of the end of the block 705 is T-shaped, so it can be fixed after the battery tray orientation adjustment is completed.

[0025] As a technical optimization solution of the utility model, Figure 1 and Figure 3As shown, the clamping structure 5 includes a rotating rod 501 and a screw rod 502. The placement plate 4 is rotatably connected to the screw rod 502. Two sliders 503 are threadedly connected to the screw rod 502. The sliders 503 are slidably connected to the placement plate 4. A clamping block 504 is fixedly connected to the slider 503. The thread directions at both ends of the screw rod 502 are opposite. The two sliders 503 are symmetrically distributed about the middle part of the screw rod 502. Therefore, when the battery tray is placed on the placement plate 4, it can be fixed.

[0026] As a technical optimization solution of the utility model, Figure 3 As shown, two rotating rods 501 are fixedly connected to both ends of the screw rod 502 . The rotating rods 501 pass through the screw rod 502 and are perpendicular to the screw rod 502 , so that the screw rod 502 can be easily rotated.

[0027] When the battery tray is in use, the battery tray can be placed on the placement plate 4 when it is needed to weld the battery tray. When the battery tray is placed, the screw rod 502 can be rotated by the rotating rod 501, and the rotation of the screw rod 502 will threadably drive the two sliders 503 to move, and the slider 503 will drive the clamping block 504 to move, so that the two clamping blocks 504 move toward the battery tray at the same time. When the two clamping blocks 504 are tightly abutted against the battery tray, the rotation of the screw rod 502 can be stopped. At this time, the battery tray is fixed, thereby preventing the battery tray from moving during the welding process, effectively improving the stability of welding. When different parts of the battery tray need to be welded, the connecting seat 2 can be rotated, and the connecting seat 2 will drive the turntable 8 to slide on the support seat 1, and the battery tray will rotate with the connecting seat 2. When the battery tray rotates to a specified angle, the placement plate 4 can be pushed to make the two connecting shafts 3 slide on the connecting seat 2, and the battery tray will move with the placement plate 4. When the orientation adjustment of the battery tray is completed, the electric push rod 701 can be started, and the electric push rod 701 will retract. Drive the slide bar 702 to slide on the connecting rod 6, and the movement of the slide bar 702 will drive the block 705 to move. During the movement, the block 705 will contact the plate 708 and move toward the connecting plate 9 on the two guide pillars 707. After the plate 708 contacts the connecting plate 9, the block 705 will slide between the slide bar 702 as the slide bar 702 continues to move, and the spring 706 will shrink. Next, the movement of the slide bar 702 will drive the sleeve 703 to move, and the sleeve 703 will drive the piece 704 to slide on the turntable 8. When one side of the piece 704 After being pressed against the support seat 1, the electric push rod 701 stops contracting. Since the support piece 704 is pressed against the support seat 1 at this time, the turntable 8 cannot rotate on the support seat 1. At the same time, under the action of the spring 706, the support plate 708 is pressed against the connecting plate 9, so the placement plate 4 cannot move. At this time, the battery tray cannot move, thereby completing the adjustment of the battery tray's orientation. By flexibly adjusting the orientation of the battery tray, the need for staff to hold welding tools in a large range of activities can be avoided, thereby saving time and physical strength and improving welding efficiency.
