[0030] 1. An adjustment mechanism is provided. First, the calibration block is placed on the outside of the mandrel. Since the diameter of the positioning pin is larger than that of the mandrel, the calibration block is fixed on the mandrel.

The position of the upper positioning sleeve is adjusted so that the bottom surface of the upper measuring plate fits with the top surface of the auxiliary plate. At this time, the upper measuring plate is in the initial position. After grinding the lower electrode, the calibration block is placed on the outside of the mandrel. The operation is repeated so that the calibration block fits with the lower electrode and the top surface of the lower measuring plate fits with the bottom surface of the auxiliary plate. At this time, the positions of the upper and lower measuring plates are obtained. Then, the positioning rod is pulled out and the top seat is fixed to the mounting plate.

The calibration block compresses the positioning pin, and the positioning pin is pressed down to drive the sliding rod to move. The sliding rod drives the bottom block at the bottom to squeeze the reset spring. The reset spring is forced to shrink until the workpiece fits the lower electrode. When the upper electrode moves up and resets, the elastic force of the reset spring drives the bottom block and the sliding rod to move, and the sliding rod drives the positioning pin to rise and reset. The positioning pin drives the limit ring to move until the limit ring is stuck in the top surface of the limit groove to complete the reset, which is convenient for subsequent welding processing of the workpiece.

[0053] Embodiment 1: Figure 1-3 and Figure 6 As shown, an adjustment mechanism is provided. First, the calibration block 16 is placed on the outside of the push rod 21, and then the upper locking bolt 31 is loosened, and the upper electrode 6 is pressed down so that the bottom surface of the calibration block 16 fits with the top surface of the lower electrode 10, and the position of the upper positioning sleeve 28 is adjusted so that the bottom surface of the upper measuring plate 29 fits with the top surface of the auxiliary plate 17, and the upper locking bolt 31 is screwed in to complete the positioning of the upper measuring plate 29.

The position of the upper electrode 6 is lowered, and the upper electrode 6 drives the reference plate 40 to move until the bottom surface of the reference plate 40 fits with the top surface of the lower measuring plate 29, completing the lowering of the upper electrode 6.

[0059] Embodiment 2: Figure 4-5 and Figure 7-10 As shown, when placing the workpiece, the calibration block 16 is placed on the outside of the push rod 21, and the upper electrode 6 is pressed down to the top surface of the calibration block 16, and will continue to press down the calibration block 16, and the calibration block 16 compresses the positioning pin 18, and the positioning pin 18 is pressed down to drive the slide bar 12 to move, and the slide bar 12 drives the bottom block 13 at the bottom to squeeze the reset spring 15, and the reset spring 15 is forced to shrink until the workpiece fits with the lower electrode 10. When the upper electrode 6 moves up and resets, the elastic force of the reset spring 15 drives the bottom block 13 and the slide bar 12 to move, and the slide bar 12 drives the positioning pin 18 to rise and reset, and the positioning pin 18 drives the limit ring 20 to move until the limit ring 20 is stuck on the top surface of the limit groove 19 to complete the reset, which is convenient for subsequent workpiece welding processing.

[0060] Working principle: When using the device, first, Figure 1-10As shown, first, the calibration block 16 is placed on the outside of the top rod 21. Since the diameter of the positioning pin 18 is larger than the top rod 21, the calibration block 16 is fixed on the top rod 21. Then the upper locking bolt 31 is loosened. When placing the workpiece, the calibration block 16 is placed on the outside of the top rod 21, and the upper electrode 6 is pressed down to the top surface of the calibration block 16, and will continue to press down the calibration block 16. The calibration block 16 compresses the positioning pin 18, and the positioning pin 18 is pressed down to drive the slide bar 12 to move, and the slide bar 12 drives the bottom block 13 at the bottom to squeeze the reset spring 15. The reset spring 15 is forced to shrink until the workpiece fits with the lower electrode 10. When the upper electrode 6 moves up and resets, the elastic force of the reset spring 15 drives the bottom block 13 and the slide bar 12 to move, and the slide bar 12 drives the positioning pin 18 to rise and reset, and the positioning pin 18 drives the limit ring 20 to move until the limit ring 20 is stuck on the top surface of the limit groove 19 to complete the reset, which is convenient for subsequent workpiece welding processing.

[0061] Press down the upper electrode 6 so that the bottom surface of the calibration block 16 fits with the top surface of the lower electrode 10, adjust the position of the upper positioning sleeve 28 so that the bottom surface of the upper measuring plate 29 fits with the top surface of the auxiliary plate 17, screw in the upper locking bolt 31, complete the positioning of the upper measuring plate 29, and the upper measuring plate 29 is in the initial position.

[0062] After welding a certain number of workpieces and grinding the lower electrode 10, the distance between the top surface of the lower electrode 10 and the workpiece increases, and then the calibration block 16 is placed on the outside of the top rod 21. The operation is repeated to make the calibration block 16 fit with the lower electrode 10, and the position of the lower measuring plate 29 is adjusted so that the top surface of the lower measuring plate 29 fits with the bottom surface of the auxiliary plate 17 to obtain the positions of the upper and lower measuring plates 29. Then the positioning rod 24 is pulled out, and the top seat 26 is fit with the mounting plate 5, so that the mounting pin 32 is inserted into the mounting hole 27 to complete the fixation of the positioning rod 24. At this time, the top surface of the reference plate 40 fits with the bottom surface of the upper measuring plate 29.

[0063] Since the auxiliary plate 17 and the reference plate 40 have the same thickness, the upper electrode 6 can be adjusted inside the mounting tube 34 by loosening the fixing bolts 38. The position of the upper electrode 6 is lowered, and the upper electrode 6 drives the reference plate 40 to move until the bottom surface of the reference plate 40 fits with the top surface of the lower measuring plate 29, completing the lowering of the upper electrode 6. The adjustment distance of the upper electrode 6 is the same as the distance the lower electrode 10 descends after grinding. There is no need to adjust the placement position of the calibration block 16, and the workpiece and the lower electrode 10 can be completely in contact, so that no gap will appear between the workpiece and the lower electrode 10, thereby improving the subsequent welding quality.
