Description

Technical Field

[0001] The utility model belongs to the technical field of seat processing equipment, in particular to a seat back welding tool. Background Art

[0002] The seat back welding jig is a device or apparatus specially designed to assist in the welding of seat back structures. By fixing and positioning the various components of the seat back, this jig ensures the accuracy, consistency and efficiency of the welding process.

[0003] For example, a Chinese utility model patent with announcement number CN219521029U discloses a seat back welding tool. The device enables the seat back frame to be attached to the front of the mounting plate through the mutual cooperation between the mounting plate, the clamping plate and the movable fixing component. The back frame can be clamped and fixed by the clamping plate, and the pipe can be clamped and fixed by the movable fixing component. The pipe can be welded to the back frame. The horizontal sliding movable fixing component can adjust the position of the pipe, and the pipe can be vertically welded to the required position of the back frame, which effectively solves the problem of difficult welding operation when welding vertical pipes on the frame.

[0004] This device can only clamp a single pipe in actual use. Since multiple pipes are usually welded on the seat back, it is difficult to ensure the consistency of the distance between adjacent pipes when welding the pipes, which easily leads to differences in the distance between adjacent pipes, thereby affecting the aesthetics of the seat back welding.

[0005] In summary, there is a need for a seat back welding tool that is convenient for welding multiple pipes at the same time. Utility Model Content

[0006] The utility model aims to provide a seat back welding tool. By arranging movable clamps and fixed clamps for clamping pipes on the fixed block and two sets of sliding brackets, multiple sets of pipes can be clamped at the same time to ensure the consistency of the spacing between two adjacent sets of pipes.

[0007] The utility model solves the above problems by adopting a technical solution: a seat back welding tool, comprising:

[0008] A bottom plate, a fixed plate is fixedly connected to the upper side of one side of the bottom plate through a support rod, a moving groove is provided on the fixed plate, a bidirectional screw rod is rotatably connected inside the moving groove, a moving block is screwed to the positive and negative threads on the bidirectional screw rod, and a clamping frame is fixedly connected to the moving block;

[0009] The movable clamping plate and the fixed clamping plate are arranged between the clamping frames and are used to clamp the pipes welded on the seat back. A plurality of movable clamping plates and fixed clamping plates are arranged, and the number of movable clamping plates and fixed clamping plates is equal.

[0010] A further preferred technical solution is that it also includes a spacing adjustment component, which includes a fixed block fixedly connected to the movable groove, a sliding bracket is provided on the fixed block and the sliding bracket is slidably connected to the fixed plate, a connecting frame is fixedly connected to the fixed plate, the fixed block is also provided with a bar frame and the bar frame and the connecting frame are fixedly connected, a slider is slidably connected to the inner side surface of the bar frame, and a connecting rod is hinged between the slider and the sliding bracket through a hinge.

[0011] A further preferred technical solution is that: a strip groove is provided on the strip frame, a screw is fixedly connected to the slider and the screw passes through the strip groove, and a clamping nut is threadedly connected to the screw.

[0012] A further preferred technical solution is that: a connecting plate is fixedly connected to the fixed block and the sliding bracket, a movable splint is provided on one side of the connecting plate, a lead screw is rotatably connected to one side of the movable splint and the lead screw and the connecting plate are threadedly connected, and a fixed splint is also fixedly connected to the fixed block and the sliding bracket.

[0013] A further preferred technical solution is that the moving block is slidably connected to the moving groove.

[0014] A further preferred technical solution is that a limiting ring is provided on the fixing sleeve of the sliding block.

[0015] A further preferred technical solution is that: a first anti-slip pad is provided on the clamping frame.

[0016] A further preferred technical solution is that a guide rod is fixedly connected to the movable clamping plate and the guide rod is slidably connected to the connecting plate.

[0032] A bottom plate 1, a fixed plate 2 is fixedly connected to one side of the bottom plate 1 through a support rod, a moving groove is provided at the front end of the fixed plate 2, a bidirectional screw rod 3 is rotatably connected to the inside of the moving groove, one end of the bidirectional screw rod 3 is coaxially fixedly connected to a hand wheel, both sides of the bidirectional screw rod 3 are threadedly connected to the outside of the moving block 4, a clamping frame 5 is fixedly connected to the outside of the moving block 4, the moving block 4 is slidably connected to the moving groove, and can play a certain guiding role in the horizontal movement of the clamping frame 5, and the opposite surfaces of the two groups of clamping frames 5 are provided with first anti-slip pads, which can improve the stability of clamping the seat back frame;

[0033] The spacing adjustment component includes a fixed block 101 fixedly connected to the middle of the movable groove, sliding brackets 102 are symmetrically arranged on both sides of the fixed block 101, and the sliding brackets 102 are slidably connected to the fixed plate 2, and the top and bottom centers of the fixed plate 2 are fixedly connected to connecting frames 103, and bar frames 104 are arranged above and below the fixed block 101, and the bar frames 104 are fixedly connected to the connecting frames 103 on the same side, and a slider 105 is slidably connected to the inner side surface of the bar frame 104, and a connecting rod 106 is hinged between the slider 105 and the sliding bracket 102 through a hinge, and limit rings 107 are fixedly sleeved on the outside of both sides of the slider 105 to prevent the slider 105 from detaching from the bar frame 104.

[0034] A strip groove 201 is formed on the outside of the strip frame 104 , a screw rod 202 is fixedly connected to the outside of the slider 105 and the screw rod 202 passes through the strip groove 201 , and a compression nut 203 is threadedly connected to the outside of the screw rod 202 .

[0035] The outside of the fixed block 101 and the sliding bracket 102 are both fixedly connected with a connecting plate 6, and a movable splint 7 is arranged on one side of the connecting plate 6. A lead screw 8 is rotatably connected to one side of the movable splint 7, and the lead screw 8 and the connecting plate 6 are threadedly connected. The end of the lead screw 8 is coaxially fixedly connected with a knob.

[0036] The implementation principle of a seat back welding tool in the embodiment of the present application is as follows: first, the seat back frame is placed vertically on the base plate 1, and then the hand wheel is turned to drive the bidirectional screw rod 3 to rotate. The rotation of the bidirectional screw rod 3 will drive the two sets of movable blocks 4 to move toward each other, thereby driving the two sets of clamping frames 5 to move toward each other to clamp the seat back frame, and then a plurality of pipes are placed in sequence between the three sets of fixed splints 9 and the movable splint 7, and by rotating the screw 8 and slidingly cooperating between the guide rod 10 and the connecting plate 6, the movable splint 7 can be driven to move closer to the fixed splint 9 to clamp the pipe. After the clamping operation is completed, the pipe is just on the inner side of the seat back frame, and then the pipe and the seat frame can be welded, and by providing a structure for clamping the pipe on the fixed block 101 and the two sets of sliding brackets 102, It is capable of clamping multiple groups of pipes at the same time, thereby improving the welding efficiency of the seat back.

When the adjustment is completed, by tightening the clamping nut 203, the position of the slider 105 can be fixed and limited, so that the position of the pipe can be fixed, thereby ensuring the stability of the pipe when the seat back is welded, and finally the welded seat back can be removed.
