DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a fixing seat 2 is provided above the bottom plate 1, and a lower electrode 3 is provided above the fixing seat 2. Fixing seats 2 4 are provided on both sides of the fixing seat 2 above the bottom plate 1, and a floating V-shaped positioning block 5 is installed above the fixing seat 2 4. An axial positioning block 6 is provided at one end above the bottom plate 1. The axial positioning block 6 plays a positioning function on one side of the workpiece to be processed. An axial tightening cylinder 7 is provided at the other end above the bottom plate 1. The axial tightening cylinder 7 plays a role in further fixing the workpiece to be processed. A positioning pin 8 is embedded in the floating V-shaped positioning block 5 on one side. The positioning pin 8 is used to fix the rotation direction of the workpiece around the axis. A guide column and guide sleeve 9 is provided on the side above the bottom plate 1. The guide column and guide sleeve 9 plays a role in supporting the electrode fixing plate 10 and provides a guiding effect under the electrode fixing plate 10. The top of the guide column and guide sleeve 9 is connected to the electrode fixing plate 10, as shown Figure 2As shown, an upper electrode 11 and a backing block 12 are provided below the electrode fixing plate 10. One side of the upper electrode 11 rests against the backing block 12. The backing block 12 provides a limiting function for the upper electrode 11. The electrode locking block 13 presses the upper electrode 11 below the electrode fixing plate 10. The electrode locking block 13 serves to fix the upper electrode 11.

[0018] The fixing seat 2 is U-shaped, and the two lower electrodes 3 are fixed on both sides of the top of the fixing seat 2. The top of the lower electrode 3 is a concave arc. The lower electrode 3 and the upper electrode 11 are energized together. At the same time, the concave arc setting enables the lower electrode 3 to support the workpiece.

[0019] A guide column 14 is provided below the floating V-shaped positioning block 5, and the guide column 14 is inserted into the fixed seat 2 4. A spring 15 is provided outside the guide column 14, and the bottom of the spring 15 is supported on the fixed seat 2 4. The top of the spring 15 supports the bottom of the floating V-shaped positioning block 5. The floating V-shaped positioning block 5 supports the workpiece, and the spring 15 plays a downward pressure buffering role. At the same time, the floating V-shaped positioning block 5 is removable and replaceable, and the two floating V-shaped positioning blocks 5 can exchange positions with each other.

[0020] A groove 19 is provided under the electrode fixing plate 10, and two electrode locking blocks 13 are against the sides of the groove 19. The electrode locking blocks 13 press the upper electrode 11, and the electrode locking blocks 13 are locked to the electrode fixing plate 10 with screws. Loosen the screws and remove the electrode locking blocks 13, then the upper electrode 11 can be removed and replaced.

[0021] The axial tightening cylinder 7 is installed on the support seat 18, and two adjusting locking blocks 17 are provided above the bottom plate. The adjusting locking blocks 17 press the two sides of the bottom of the support seat 18. The support seat 18 is slidably connected to the adjusting locking blocks 17. The adjusting locking blocks 17 provide a guide for the axial tightening cylinder 7.

[0022] Two sensors 16 are installed on one side of the fixing base 2. The sensors 16 distinguish the left and right parts by identifying the different features of the left and right part bracket positions.

[0023] There are two lower electrodes 3, which can be disassembled for easy replacement.

[0024] The upper electrode 11 is a contoured magnet.

[0025] When the present invention is used, technicians lift the left and right workpieces respectively through two floating V-shaped positioning blocks 5, and the two ends of the left and right workpieces overlap at the lower electrode 3 above the fixed seat 2. After placement, the workpiece is pushed to the axial positioning block 6 by the axial tightening cylinder 7 and fixed. The guide column and guide sleeve 9 shrink, and the electrode fixing plate 10 is pressed down. The upper electrode 9 is pressed toward the workpiece under the drive of the equipment, and the bottom of the workpiece contacts the lower electrode 3, and the top of the workpiece contacts the upper electrode 9. The tooling is energized to achieve projection welding. Among them, the floating V-shaped positioning block 5 can be quickly pulled out and replaced. The screws are loosened to remove the electrode locking block 13, and the upper electrode 11 can be removed to achieve rapid tooling change or rapid replacement of damaged parts. The two sensors recognize the different characteristics of the left and right parts bracket positions to identify the left and right parts positions, which can save the tedious steps of identifying the left and right parts during loading, save time, and prevent production errors in subsequent processes.
