[0029] The above embodiment of the invention provides a hardware welding fixture, the working principle of which is as follows: 1. Initial preparation stage Clamp Position Adjustment: Initially, the two clamping bodies 320 face the front of the device body 100. Depending on the length of the hardware to be welded, the positioning assembly 330 drives the two movable support components 340 to slide synchronously in opposite directions along the steering spindle 310, driving the clamping bodies 320 to move, quickly adjusting the distance between them to match the hardware length.

[0030] The working process of the positioning component: the adjusting cylinder 332 pushes / pull the push-pull seat 331, and the hinged adjusting arm 333 pulls or pushes the guide seat 342, so that the support sleeve 341 moves along the steering spindle 310, realizing the synchronous opening and closing of the clamping body 320.

[0031] Angle Pre-Adjustment (Optional): If the hardware requires tilting, operate the locking unit 350 (pull the release lever 354 to disengage the locking sleeve 352 from the sleeve 370) to release the rotation restriction of the clamping body 320. After manually rotating the clamping body 320 to the desired angle, release the locking unit 350 (the torsional damping bearing returns to its original position, causing the locking sleeve 352 to engage the ridge of the sleeve 370), fixing the angle.

[0032] 2. Hardware clamping stage Place the hardware: Place the hardware to be welded into the C-shaped grooves of the two supporting clamps 321 respectively, ensuring that the welding end is located between the two clamping bodies 320.

[0033] Clamping operation: Internal clamping: Twist the clamping screw 323 to push the clamping plate 322 toward the hardware, and cooperate with the inner wall of the supporting clamp seat 321 to clamp the hardware.

[0034] External clamping (automatic linkage): When the clamping plate portion 322 moves, the linkage rack 328 drives the clamping gear 327 to rotate, causing the clamping shaft 324 to rotate.

[0035] The pressing support arm 325 swings accordingly, driving the pressing block 326 to press the hardware from the outside, forming a double clamping inside and outside to prevent it from falling off.

[0036] 3. Welding and position adjustment stage Suspended welding: The clamped hardware is suspended on the welding table 200, making it easier for the welding gun component 400 to approach the welding point from multiple angles.

[0037] Rotary welding (multi-sided welding): Activating the steering motor 311 rotates the steering spindle 310. This, in turn, moves the support assembly 340 (support sleeve 341, support rod shaft 360, and sleeve portion 370), driving the clamping body 320 and the hardware components as a whole. The hardware rotates around the axis of the steering spindle 310, exposing unwelded areas and achieving continuous, multi-sided welding, eliminating blind spots.

[0038] 4. Collaboration among key institutions The support member 340 includes a support sleeve 341 that slides along the steering spindle 310 to adjust the spacing and transmit rotational power. The guide seat 342 slides with the built-in side plate 210 to ensure movement stability.

[0039] The locking unit 350 controls the rotational freedom of the clamping body 320 by engaging / disengaging the locking sleeve 352 with the ridges of the sleeve portion 370, thereby ensuring rigid fixation after angle adjustment.

[0040] External pressure unit: Automatically triggers the external pressure of the clamping block 326 when clamping to enhance the clamping force, especially suitable for special-shaped or slippery hardware.

[0041] The present invention also provides a hardware welding device, which includes an equipment body 100 and the hardware welding fixture described in the above embodiment. The hardware welding fixture is arranged at the front end of the equipment body 100 and a welding gun component 400 for performing welding actions on hardware is installed on the side of the equipment body 100.
