Description

Technical Field

[0001] The present invention relates to the technical field of clamps, in particular to a welding clamp for automobile seats. Background Art

[0002] A fixture is a device used to fix the object to be processed during the mechanical manufacturing process so that it occupies the correct position for construction or testing.

[0003] During the production of automotive seats, which are often complex components, welding of the seat frames is necessary. However, seat frames are often complex, requiring custom welding fixtures. Common seat frame welding fixtures typically install corresponding fixtures on a baseplate to secure the various components of the seat frame. Therefore, the holes in the baseplate for securing the fixtures are located in specific locations and are not universally applicable to other seat frame types. Furthermore, after welding, the fixtures must be opened one by one, making removal of the seat frame a tedious process. Summary of the Invention

[0004] To address the above issues, the present invention discloses a car seat welding fixture comprising a clamping platform with a plurality of support members and clamping units disposed on the upper end of the clamping platform. An appropriate number of support members and clamping units are selected based on actual welding requirements and arranged on the clamping platform.

[0005] The clamping platform includes a base, and a sliding plate and a fixed plate are arranged side by side at the upper end of the base, and the sliding plate and the base are slidably matched. The fixed plate is fixedly connected to one side of the base, and an opening is provided in the middle of the base, and an electric cylinder is fixedly connected in the opening. The output end of the electric cylinder is fixedly connected to the lower end of the sliding plate. By starting the electric cylinder, the sliding plate can be moved away from or closer to the fixed plate. The clamping units used here appear in pairs, and a clamping unit is provided on the fixed plate, and a corresponding clamping unit is also provided on the sliding plate. When the fixed plate and the sliding plate are close to each other, the clamping effect is achieved. When the baffle plate and the sliding plate are moved away from each other, the clamping is loosened, and the workpiece can be removed. This method has the advantage of convenient removal of the workpiece. It should be noted that the same support member and clamping unit cannot be installed on the fixed plate and the sliding plate at the same time, otherwise the relative positions of the fixed plate and the sliding plate will be fixed.

[0006] The clamping unit includes a connecting arm, one end of which is fixedly connected to a column. A telescopic rod extends from the upper end of the column, and the telescopic rod and the column are rotatably coupled. The upper end of the telescopic rod is fixedly connected to a U-shaped member, a rotating block is rotatably connected to the U-shaped member, and a supporting member is fixedly connected to the rotating block. The clamping unit can be adjusted in terms of degrees of freedom such as lifting and rotation, which has the advantage of versatility and expands the scope of application of the clamping unit. The supporting member is also customized, and its end is provided with holes and grooves that match the surface of the workpiece to be contacted, so as to ensure close contact with the workpiece and achieve stable clamping.

[0007] Preferably, the upper ends of the sliding plate and the fixed plate are provided with T-shaped slots in both the vertical and horizontal directions. In the traditional form, basically only holes for installing the fixture are provided, and the positions thereof are relatively fixed.

[0008] Preferably, the support member includes a support column, with first bolts inserted downwardly on both sides of the lower end of the support column. The lower ends of the first bolts are threadedly connected to first retaining rings, which fit within the T-shaped slots. The upper end of the support column is also provided with a hole slot that matches the surface of the workpiece. The provision of the first retaining ring and the first bolt, coupled with the T-shaped slots, allows the position of the support member to be more adjustable, thereby increasing the versatility of the device.

[0009] Preferably, a second bolt is inserted into the other end of the connecting arm, and a second retaining ring is threadedly connected to the end of the second bolt, and the second retaining ring fits into the T-slot. This is consistent with the fixing method of the support member. In addition, after the position of one end of the connecting arm is determined by the second bolt and the second retaining ring, the connecting arm rotates around the determined position as the center of a circle, that is, the trajectory of the other end of the connecting arm is circular, and the position of the column is not limited to directly above the T-slot. This method greatly increases the installation posture of the clamping unit and improves the versatility of the device.

[0010] Preferably, the base is provided with a slide rail, which slides in a preset slide groove at the lower end of the sliding plate to ensure stable sliding between the base and the sliding plate.

[0011] Preferably, a chip groove is provided on the base, and the chip groove is located below the joint edge of the sliding plate and the fixed plate to prevent waste chips from appearing between the sliding plate and the fixed plate, resulting in the inability to completely close the two.

[0012] Preferably, a third bolt is threadedly connected to the upper side wall of the column, the third bolt abutting against the side wall of the telescopic rod. A fourth bolt is provided on the U-shaped member, the fourth bolt intersecting the U-shaped member and the rotating block. The third bolt is used to secure the telescopic member after adjustment, and the third bolt is used to secure the rotating block after adjustment.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The T-slots arranged vertically and horizontally, combined with fasteners and bolts, achieve diversified connection positions. The clamping unit is also practical. The clamping unit itself has multiple degrees of freedom of adjustment, which makes the device universal.

[0015] 2. A sliding plate and a fixed plate are provided, which move relative to each other, making it easy to remove the workpiece after welding. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figures 1 to 4 As shown, a car seat welding fixture includes a clamping platform 1, and a plurality of support members 2 and clamping units 3 are provided on the upper end of the clamping platform 1. The appropriate number of support members 2 and clamping units 3 is selected according to the workpiece to be clamped.

[0025] The clamping platform 1 includes a base 12, which is a plate. A sliding plate 15 and a fixed plate 17 are arranged side by side at the upper end of the base 12. The sliding plate 15 and the base 12 slide together. The fixed plate 17 is fixedly connected to one side of the base 12, so that the sliding plate 15 can be moved as needed. An opening is provided in the middle of the base 12, and an electric cylinder 13 is fixedly connected to the opening. The output end of the electric cylinder 13 is fixedly connected to the lower end of the sliding plate 15. Activating the electric cylinder 13 controls the position of the sliding plate 15. Before the device is used, the support member 2 and the clamping unit 3 must be assembled on the sliding plate 15 and the fixed plate 17. Note that a single support member 2 and clamping unit 3 can only be mounted on the sliding plate 15 or the fixed plate 17. Once assembled, the various parts of the seat are placed on the support member 2, and then the sliding plate 15 is moved close to the fixed plate 17 to achieve the clamping operation. After welding is completed, the sliding plate 15 is moved away from the fixed plate 17 to loosen the workpiece.

[0026] The clamping unit 3 includes a connecting arm 32, one end of which is fixedly connected to the column 33, and a telescopic rod 36 is extended from the upper end of the column 33, that is, by adjusting the length of the telescopic rod 36, the clamping height can be adjusted, and the telescopic rod 36 and the column 33 are rotatably coordinated, that is, the telescopic rod 36 can be horizontally rotated relative to the column 33 to achieve rotation adjustment, and the upper end of the telescopic rod 36 is fixedly connected to a U-shaped part 37, and a rotating block 39 is rotatably connected to the U-shaped part 37. The rotating block 29 can be rotated and adjusted for the pitch angle. A supporting member 310 is fixedly connected to the rotating block 39. The supporting member 310 is a customized structure and can be detached from the rotating block 29, and the upper end of the supporting member 310 fits the contour of the surface of the workpiece, thereby clamping the workpiece more tightly.

[0027] T-slots 16 are provided at the upper ends of both the sliding plate 15 and the fixed plate 17, both vertically and horizontally. These slots secure the support member 2 and the clamping unit 3. Unlike conventional methods of bolting through pre-set holes, this solution employs T-slots 16 arranged vertically and horizontally, allowing for a wider variety of connection locations.

[0028] Support member 2 includes a support column 23. First bolts 22 are inserted downwardly on both sides of the lower end of support column 23. The lower end of first bolt 22 is threadedly connected to a first retaining ring 21. First retaining ring 21 fits within T-slot 16. When first bolt 22 is tightened, first retaining ring 21 and first bolt 22 are tightened, thereby securing support member 2. Furthermore, a hole groove is provided at the upper end of support column 23 that matches the surface of the workpiece, achieving close contact with the workpiece and providing more stable support for the workpiece.

[0029] A second bolt 34 is inserted through the other end of the connecting arm 32. The end of the second bolt 34 is threadedly connected to a second retaining ring 31, which fits into the T-slot 16. This means that the clamping unit 3 is secured to the clamping platform 1 in the same manner as the support member 2. The connecting arm 32 is provided here. Once one end of the connecting arm 32 is positioned, the other end can rotate around that position, thereby increasing the diversity of connections and enhancing the versatility of the dedicated device.

[0030] The base 12 is provided with a slide rail 11, which is slidably fitted in a preset slide groove at the lower end of the slide plate 15, thereby ensuring stable sliding of the slide plate 15.

[0031] A chip groove 14 is provided on the base 12, and the chip groove 14 is located below the joint edge of the sliding plate 15 and the fixed plate 17. During use, debris such as welding slag will fall on the base 12, causing the sliding plate 15 and the fixed plate 17 to not close properly. After the chip groove 14 is provided, the debris will be pushed into the chip groove 14 by the sliding plate 15 to operate, ensuring that the sliding plate 15 is stable in place. It should be noted that the debris in the chip groove 14 needs to be cleaned regularly.

[0032] The upper side wall of the column 33 is threadedly connected with a third bolt 35, which abuts the side wall of the telescopic rod 36. After the height adjustment of the telescopic rod 36 is completed, the third bolt 35 is tightened to fix it. A fourth bolt 38 is provided on the U-shaped part 37, and the fourth bolt 38 is inserted into the U-shaped part 37 and the rotating block 39. After the inclination angle adjustment of the U-shaped part 37 is completed, the third bolt 35 is tightened.

[0033] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above-mentioned embodiment, but also include technical solutions composed of any combination of the above technical features.
