[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0025] See Figures 1 to 3 The quick-change device for an automotive seat welding fixture shown includes a quick-change base 10, a sliding assembly 20, a sensor 30, a positioning assembly 40, a clamping assembly 50, and a control valve 100 disposed on the quick-change base 10 for controlling the operation of the sliding assembly 20, the positioning assembly 40, and the clamping assembly 50.

[0026] This embodiment also includes two buffers 60 disposed on the quick-change base 10 and cooperating with the welding fixture 1. The two buffers 60 are respectively disposed at a distance on the quick-change base 10 and located on one side of the sliding assembly 20. The control switches of the two buffers 60 are also controlled by the control valve 100.

[0027] The quick base 10 is a square workbench. The bottom of the quick base 10 is provided with lifting cylinders for raising the sliding component 20, the positioning component 40, and the pressing component 50. The lifting cylinders are connected to the control valve 100.

[0028] The sliding component 20 is disposed on the quick-change base 10 and cooperates with the welding fixture 1. In this embodiment, the sliding component 20 includes two pulley balls 21 disposed on the quick-change base 10 and connected to the control valve 50. The two pulley balls 21 are respectively disposed at intervals on the quick-change base 10 and correspond to the positions of the two buffers 60.

[0029] Sensor 30 is installed on quick-change base 10 and is used to monitor the arrival of welding fixture 1 in the work area. When in use, the worker pushes welding fixture 1 to the side of quick-change base 10 using logistics cart 2, the foot brake keeps logistics cart 2 stationary, the manual valve 100 is activated to raise pulley ball 21, the worker pushes welding fixture 1 onto pulley ball 21, welding fixture 1 slides to contact buffer 60 by inertia and slowly enters the position, and after sensor 30 detects that welding fixture 1 has entered the position, the next step is performed.

[0030] The positioning component 40 is mounted on the quick-change base 10 and is used to position the welding fixture 1. In this embodiment, the positioning component 40 includes two positioning pins 41 mounted on the quick-change base 10 and connected to the control valve 100. Each positioning pin 41 is located on one side of each pulley ball 21 and cooperates with the welding fixture 1. In use, when the welding fixture 1 reaches the position, the manual valve 100 is activated to lower the pulley ball 21, and the positioning pin 41 extends and enters the positioning hole 1a of the welding fixture 1, thereby achieving fixation.

[0031] The clamping assembly 50 is mounted on the quick-change base 10 and is used to clamp the welding fixture 1. In this embodiment, the clamping assembly 50 includes four clamping arms 51 mounted on the quick-change base 10 and connected to the control valve 100. Each pair of clamping arms 51 is located on one side of each pulley ball 21 and cooperates with the welding fixture 1. When the welding fixture 1 is fixed, the manual valve 100 actuates to clamp the four clamping arms 51 to fix the welding fixture 1, and welding can then be produced.

[0032] The welding fixture 1 is provided with two positioning holes 1a for two positioning pins 41 to pass through.

[0033] In use, the worker pushes the welding fixture 1 to the side of the quick-change base 10 using the logistics cart 2, fixes the logistics cart 2 with the foot brake, and raises the pulley ball 21 by operating the manual valve 100. The worker then pushes the welding fixture 1 onto the pulley ball 21. The welding fixture 1 slides onto the contact buffer 60 by inertia and slowly comes into position. After the sensor 30 detects that the welding fixture 1 has come into position, the manual valve 100 lowers the pulley ball 21, and the positioning pin 41 extends and enters the positioning hole 1a of the welding fixture 1. Inside, the manual valve 100 activates to press the clamping arm 51 to secure the welding fixture 1, allowing welding to proceed. When changing the fixture again, the logistics trolley 2 is pushed to the quick-change base 10, the foot brake is used to keep the logistics trolley 2 stationary, the manual valve 100 is activated, the clamping arm 51 opens, the positioning pin 41 retracts, the pulley ball 21 lifts the welding fixture 1, slides the welding fixture 10 onto the logistics trolley 2, and then pushes the welding fixture 1 away to replace it with the next welding fixture 1, repeating the cycle.
