[0025] Reference Figures 1 to 6 In some embodiments, the utility model discloses a handle right-angle welding fixture, which includes:

[0026] Reference Figures 1 to 3 The first column 10 shown is used to raise the height of the clamp so that the clamping mechanisms on both sides of the handle can rotate in a three-dimensional space.

[0027] Reference Figures 2 to 3 As shown, the hollow rotating platform assembly 200 mounted on the first column 10 has a compact structure. Figures 2 to 3 The hollow rotating platform assembly 200 is small in size and in sheet form. Compared with the rotating assembly in the current market, which requires a large number of components to form a variable speed transmission structure, the hollow rotating platform assembly 200 of the handle right angle welding fixture can save more space. The power input end of the hollow rotating platform assembly 200 is connected to a driving motor 300.

[0028] Specifically, combined Figure 6 One embodiment of the hollow rotating platform assembly 200 is shown. Of course, the hollow rotating platform assembly 200 can also be an assembly of other structures, which is used to input motor power and change speed. Its rotating power output end drives the heavier clamping platform 500 to rotate to complete the welding operation of the right-angle handle. The clamping platform 500 connected to the rotating power output end of the hollow rotating platform assembly 200 allows the power output end of the hollow rotating platform assembly 200 to drive the clamping platform 500 to rotate. Figure 6In the embodiment: The hollow rotary platform assembly 200 includes a base plate 210 vertically arranged on the first column 10, rollers 220, a gear ring 230 and a power output flange 240. The rollers 220 and the gear ring 230 are installed on the base plate 210 and are meshed and connected with each other. The motor shaft of the drive motor 300 is sleeved with the gear ring 230, and the power output flange 240 is in transmission connection with the clamping platform 500. Preferably, the drive motor 300 is a servo motor. The servo motor drives the rollers 220 to rotate, which is meshed and connected with the rollers 220 and the gear ring 230. The rollers 220 with a small radius drive the gear ring 230 to output a large torque to drive the clamping platform 500 and the clamping mechanism 600 to rotate, accurately driving the adjacent parts of the two right-angle sides to be welded and fixed in sequence, forming a right-angle handle in a right-angle shape.

[0029] Referring to Figure 3 As shown, the clamping mechanism 600 arranged on the clamping platform 500 includes a first clamping component 610 for vertically moving up and down to press one side of the right-angle handle workpiece and a second clamping component 620 for vertically moving up and down to press the other side of the right-angle handle workpiece. The two sides of the right-angle handle are accurately positioned and clamped by the first clamping component 610 and the second clamping component 620 respectively. The welding torch orifice is arranged adjacent to the right-angle welding fixture of the handle. The two sides of the right-angle handle workpiece clamped by the two clamping components are in contact with each other, and the periphery is welded by welding at the contact part of the two sides of the handle. This welding fixture uses manual feeding of materials to the first clamping component and the second clamping component semi-automatically. The fixture clamps and positions the handle workpiece, and the drive motor 300 drives the clamping platform 500 and the clamping mechanism 600 to rotate through the hollow rotary platform assembly 200, accurately driving the adjacent parts of the two right-angle sides to be automatically welded and fixed in sequence, forming a right-angle handle in a right-angle shape.

[0030] Referring to Figures 2 to 4 As shown, in order to enable this right-angle welding fixture of the handle to adapt to the clamping and welding operations of right-angle handle workpieces with various outer diameter sizes, the first clamping component 610 includes a first base 611 for placing one side of the right-angle handle workpiece, a first pressing part 612 corresponding to the upper part of the first base 611, and a first cylinder 613 in transmission connection with the first pressing part 612 to drive it to move up and down. The second clamping component 620 includes a second base 621 for placing one side of the right-angle handle workpiece, a second pressing part 622 corresponding to the upper part of the second base 621, and a second cylinder 623 in transmission connection with the second pressing part 622 to drive it to move up and down. The second cylinder 623 is installed on the clamping platform 500. The first pressing part 612 and the second pressing part 622 control the height of moving up and down through the cylinders respectively, so that handles with various outer diameter sizes can be commonly pressed and welded in this fixture.

[0031] Continue to refer to Figure 3 and Figure 4 As shown, the clamping platform 500 includes a first sub-clamping platform part 510 and a second sub-clamping platform part 520 on the same plane as the first sub-clamping platform part 510. The first cylinder 613 is installed on the first sub-clamping platform part 510, and the second cylinder 623 is installed on the second sub-clamping platform part 520. In order to enable the operator to load the two sides of the handle with different lengths, refer to Figures 3 to 4 As shown, the first sub-clamping platform part 510 is connected to the rotational power output end of the hollow rotary platform assembly 200. The rotational power output end of the hollow rotary platform assembly 200 is also connected to a third cylinder 530. The power end of the third cylinder 530 is connected to the second sub-clamping platform part 520. There is a moving gap between the first sub-clamping platform part 510 and the second sub-clamping platform part 520 to allow the third cylinder 530 to drive the second sub-clamping platform part 520 to move within the moving gap. Clamp the two sides of the right-angle handle respectively. There is a gap between the second sub-clamping platform part and the first sub-clamping platform part that can be adjusted, so that the fixture can also adapt to various lengths of handle workpieces for clamping. Then, the third cylinder 530 drives the second sub-clamping platform part 520 to move within the moving gap, so that the two sides of the handle are in contact for welding operations.

[0032] In order to make the movement of the second sub-clamping platform 500 more precise, refer to Figure 4 As shown, the second sub-clamping platform 500 is slidably connected to a first slide rail member 540. The direction of the first slide rail member 540 is the same as the direction of the third cylinder 530. The end of the first slide rail member 540 is fixedly connected to the rotational power output end through a connecting plate. Adding the first slide rail member 540 to the second sub-clamping platform 500 greatly improves the accuracy of the sliding movement.

[0033] Refer to Figure 3 As shown, it further includes a positioning component 700. The positioning component 700 includes a second column 710, a positioning rod 720 with a horizontal direction arranged on the second column 710, and one end of the positioning rod 720 is connected to a fourth cylinder 730 for driving horizontal movement. The other end of the positioning rod 720 is oriented to cooperate with the right-angle position of the right-angle handle workpiece for positioning. When the operator is loading the material, the other end of the positioning rod 720 is oriented to cooperate with the right-angle position of the right-angle handle workpiece for positioning. After loading the right-angle handle, the fourth cylinder drives the positioning rod 720 to retract, and the two side handle workpieces rotate for welding.

[0034] In order to increase the accuracy of the movement of the positioning rod 720, the positioning rod 720 cooperates with a second slide rail member 740 for sliding operation. Refer to Figure 3As shown, the positioning component 700 includes a second slide rail member 740. One side of the positioning rod 720 is slidably connected to the second slide rail member 740. The direction of the second slide rail member 740 is the same as that of the fourth cylinder 730. The other side of the second slide rail member 740 is fixedly connected to the second column 710.
