[0019] The threaded locking piece includes a first fixed handle 3 mounted on one side of the back of the locking seat no. 2, a second fixed handle 5 on one side of the top end of the locking seat no. 2, a fourth fixed handle 7 mounted on one end of the surface of the X axle horizontal column 4, and a third fixed handle 6 mounted on one side of the outer wall of the locking seat no. 2 12.

[0020] The first fixed handle 3 is used to tighten the locking seat no. 2 and make the locking seat no. 2 tightly hold the Z axle stand 1. The second fixed handle 5 is used to tighten the locking seat no. 2 and make the locking seat no. 2 tightly hold the X axle horizontal column 4. The fourth fixed handle 7 is used to tighten the locking seat no. 2 12 and make the locking seat no. 2 12 tightly hold the Y axle vertical column 8. The third fixed handle 6 is used to tighten the locking seat no. 2 12 and make the locking seat no. 2 12 tightly hold the X axle horizontal column 4. The locking seat no. 2 and the first fixed handle 3 are the threaded locking pieces for controlling the height of the X axle horizontal column 4, the Y axle vertical column 8, the U-shaped frame 9, the screw rod force assembly 10, and the elastic abutment 11. The second fixed handle 5 and the locking seat no. 2 are the threaded locking pieces for controlling the X axle position of the X axle horizontal column 4, the U-shaped frame 9, the screw rod force assembly 10, and the elastic abutment 11. The fourth fixed handle 7 and the locking seat no. 2 12 are the threaded locking pieces for controlling the Y axle position of the Y axle vertical column 8, the U-shaped frame 9, the screw rod force assembly 10, and the elastic abutment 11.

[0021] The position of the elastic abutment 11 is adjusted according to the shape characteristics of the headlamp bottom shell in the three-axis direction.

[0022] The Y-axis vertical column 8 is provided with an internally threaded hole on the side outer wall close to the U-shaped frame 9, and the U-shaped frame 9 and the Y-axis vertical column 8 are bolted through the internally threaded hole. The screw force assembly 10 includes a nut pair 1001 fixed on one side of the top end of the U-shaped frame 9 and a threaded shaft 1002 threadedly matched with one end inside the nut pair 1001.

[0023] When the position of the elastic abutting piece 11 is adjusted, the nut pair 1001 is manually rotated by the staff, and the elastic abutting piece 11 is driven to slide in the axial direction of the threaded shaft 1002 by the nut pair 1001, so that the elastic abutting piece 11 approaches or gradually moves away from the fixed position of the headlamp bottom shell. Through the traction of the screw force assembly 10, the force exerted by the elastic abutting piece 11 on the workpiece can be accurately controlled.

[0024] The elastic abutting piece 11 includes a right-angle frame 1101 slidingly installed on the top end of the U-shaped frame 9, a T-axis column 1104 slidingly installed at the corner position of the bottom end of the right-angle frame 1101, and a rubber pressing plate 1102 fixed at the bottom end of the T-axis column 1104.

One end of the threaded shaft 1002 is rotationally connected with the outer wall of one side of the lug. When the elastic abutting piece 11 is pushed by the screw force assembly 10 and abuts against the outer wall, the deformation amount of the spiral spring 1103 is proportional to the pushing amount of the screw force assembly 10, so that the rubber pressing plate 1102 is pressed against the outer wall of the workpiece. When the rubber pressing plate 1102 contacts the outer wall of the workpiece, the rubber pressing plate 1102 drives the T-axis column 1104 to slide inside the right-angle frame 1101, so that the spiral spring 1103 is squeezed by the right-angle frame 1101 and the rubber pressing plate 1102. Through the deformation of the spiral spring 1103, the stress can be dispersed, and the damage of the workpiece during the fixing process can be reduced.

[0025] The embodiment of the application is used, first, the staff takes out a plurality of the device, and one by one Z-axis column 1 is fixed on the workbench, and ensure that all components are intact, especially the threaded locking piece, the screw force assembly 10 and the elastic abutting piece 11, and clean the workpiece table of sundries and dust, ensure that the headlamp bottom shell can be placed stably, then according to the size and shape of the headlamp bottom shell, the position of the X-axis horizontal column 4 and the Y-axis vertical column 8 is adjusted in advance, in order to better adapt to the fixing requirements of the headlamp bottom shell, the threaded locking piece is used to finely adjust the X-axis horizontal column 4 and the Y-axis vertical column 8 in the process, so that the U-shaped frame 9, the screw force assembly 10 and the elastic abutting piece 11 accurately align the position to be fixed of the headlamp bottom shell, after the elastic abutting piece 11 aligns the position to be fixed of the headlamp bottom shell, the screw force assembly 10 is used to apply appropriate pressure to the elastic abutting piece 11, so that the elastic abutting piece 11 closely fits the headlamp bottom shell, this step needs the staff to adjust the output force of the screw force assembly 10 according to the actual needs, to ensure the stability and reliability of the fixation, after confirming that the U-shaped frame 9, the elastic abutting piece 11 and the screw force assembly 10 are in the correct position, the threaded locking piece is used to firmly fix the X-axis horizontal column 4 and the Y-axis vertical column 8, after the fixation is completed, the staff should check the fixing effect of the headlamp bottom shell, if the fixing effect is not ideal, the staff should adjust and optimize according to the actual situation, including re-adjusting the position of the Y-axis vertical column 8 and the X-axis horizontal column 4, replacing the A-axis position of the elastic abutting piece 11, adjusting the output force of the U-shaped frame 9, etc.
