[0007] More preferably, a guide shaft is sleeved on the rotating seat, a third transmission gear is nested and fixed at one end of the guide shaft, a sliding shaft is sleeved on the guide seat, the sliding shaft slides along the axial direction of the guide shaft, a first bevel gear is nested and fixed at one end of the sliding shaft, and a rotatable guide screw is provided on the guide seat, a second bevel gear is nested and fixed at one end of the guide screw.
[0008] More preferably, an air storage cylinder is fixed to one side of the rotating seat, and a one-way air inlet is provided at the lower part of the air storage cylinder. A sliding column is movably passed through one end of the air storage cylinder, and a fourth return spring is connected between one end of the sliding column and one end of the air storage cylinder. A connecting pipe is fixed to one end of the air storage cylinder, and the other end of the connecting pipe is fixedly connected to the guide cylinder. A pressure relief valve is fixed to one side of the guide cylinder.
[0009] More preferably, a first fixing block is fixed to one side of the rotating seat, a second fixing block is fixed to the bottom of the guide seat, and the connecting pipe is snapped into the opening between the first fixing block and the second fixing block.
[0010] More preferably, the bottom of the rotating plate is provided with two sets of clamping assemblies. The clamping assemblies include a third servo motor, a second mounting bracket, a bidirectional lead screw, and a limiting member. The third servo motor is fixed on one side of the bottom of the rotating plate, and the second mounting bracket is fixed on the other side of the bottom of the rotating plate. A rotatable bidirectional lead screw is provided between the power output end of the third servo motor and the second mounting bracket. A slidable limiting member is provided on the bidirectional lead screw, and the limiting member slides along the guide groove opened on the rotating plate.
[0011] More preferably, the connecting block is L-shaped, one end of the second reset spring abuts against the guide block and the other end abuts against the sliding member, one end of the third reset spring abuts against the first transmission gear and the other end abuts against the connecting block, and the first transmission gear is located between the connecting blocks.

One set limits the material to the left and right, and the other set limits the material to the front and back. The side of the limiting component that contacts the material is made of rubber.
[0014] The beneficial effects of this invention are as follows: When the guide seat and the arc-shaped block fixed on one side move downward, the arc-shaped block abuts against the sliding member and slides downward along the guide block, compressing the second return spring. The connecting block slides downward along the mounting frame together, compressing the third return spring, causing the first transmission gear to move downward. After the push cylinder is reset, the second servo motor is started. Under the action of the third return spring, the first transmission gear meshes with the third transmission gear, driving the guide shaft, sliding shaft, and bevel gear to rotate together. The second bevel gear and the guide screw rotate together, causing the sliding frame to slide along the guide groove on the guide seat, moving materials such as table legs to the welding position. The lifting and lowering of the first transmission gear, and the intermittent engagement with the second and third transmission gears, increase the adjustment range, reduce the inconvenience of adjustment in traditional fixtures when changing material types, and improve production efficiency.
[0015] When the arc-shaped block abuts against the sliding component, it also abuts against the sliding column, compressing the third return spring. This causes the air in the air storage cylinder to flow into the guide cylinder along the connecting pipe, strengthening the fixing effect of the limiting column on the material. This prevents the material from sliding during movement and welding, which could lead to inaccurate welding positions and increase the welding yield. Attached Figure Description

A third return spring 22 is sleeved on the first mounting frame 8.
[0030] In practice, the arc-shaped block 14 abuts against the sliding member 20 and slides downward along the guide block 19, compressing the second reset spring 21. The connecting block 2001 slides downward along the first mounting bracket 8 together, compressing the third reset spring 22, causing the first transmission gear 9 to move downward.
[0031] Preferably, a guide shaft 24 is sleeved on the rotating seat 11, and a third transmission gear 23 is nested and fixed at one end of the guide shaft 24.

The arc-shaped block 14 will abut against the sliding column 29 and compress the fourth reset spring 30 at the same time, so that the air in the air storage cylinder 28 flows into the guide cylinder 16 along the connecting pipe 31, which strengthens the fixing effect of the limit column 17 on the material. After the welding is completed, the pressure relief valve 34 is activated, and the sliding column 29 is reset under the action of the fourth reset spring 30.

[0043] When using this device, first place the desktop frame on the rotating plate 5, start the third servo motor 35 to drive the bidirectional lead screw 37 to rotate, so that the limiting member 38 slides along the guide groove on the rotating plate 5. The bottom of the rotating plate 5 is equipped with two sets of clamping components that are staggered. One set limits the material to the left and right, and the other set limits the material to the front and back. Fix the desktop frame in the center position of the rotating plate 5. After fixing, start the second servo motor 6 to drive the pulley in the transmission component 7, so that the first transmission gear 9 rotates and the second transmission gear 10 rotates together, so that the rotating seat 11 rotates. When it rotates to the angle required for welding, the second servo motor 6 stops rotating.
[0044] Materials such as table legs are placed into the guide cylinder 16 manually or by a feeding robot. The limiting post 17 clamps the materials under the compression of the first return spring 18.

Simultaneously, the arc-shaped block 14 abuts against the sliding post 29, pressing... The fourth return spring 30 is compressed, allowing air in the air storage cylinder 28 to flow into the guide cylinder 16 along the connecting pipe 31, strengthening the fixing effect of the limit post 17 on the material. After the cylinder 12 is reset, the second servo motor 6 is started again. Under the action of the third return spring 22, the first transmission gear 9 and the third transmission gear 23 mesh, driving the guide shaft 24, the sliding shaft 25 and the first bevel gear 26 to rotate together. The second bevel gear 2601 and the guide screw 27 rotate together, causing the sliding frame 15 to slide along the guide groove on the guide seat 13, moving the table legs and other materials to the welding position.
[0045] During the welding process, the movement of the welding robot 2 and the rotation of the first servo motor 4 are controlled by an automated program. After welding is completed, the pressure relief valve 34 is activated, pushing the telescopic rod of the cylinder 12 to move upward. The limit post 17 no longer contacts the table legs and other materials. The sliding part 20 and the connecting block 2001 are reset along the guide block 19 under the action of the second reset spring 21. The sliding post 29 is reset under the action of the fourth reset spring 30. The gas re-enters the gas storage cylinder 28 from the one-way air inlet 2801. The third servo motor 35 is activated, driving the bidirectional lead screw 37 to reset the limit part 38. Then the material on the rotating plate 5 is removed.
