Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0019] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a pressing mechanism for copper sheet spot welding, which includes a mounting base plate 1. On the top of the mounting base plate 1, there is a mounting vertical plate 2. On one side of the mounting vertical plate 2, there is a reinforcing plate strip 15 for ensuring stability.

On the surface of the cylinder mounting plate 3, there is an arc-shaped mounting hole 13. Through the setting of the arc-shaped mounting hole 13, the operator can adjust the elongation angle of the copper sheet pressing head 11 in the vertical direction, improving the flexibility of the mechanism. On the surface of the cylinder mounting plate 3, there is a telescopic cylinder 4. At the driving end of the telescopic cylinder 4, there is a lifting cylinder mounting plate 5. A lifting cylinder 6 is arranged on the lifting cylinder mounting plate 5. At the driving end of the lifting cylinder 6, there is a lifting plate 7. On one side of both the telescopic cylinder 4 and the lifting cylinder 6, there is a limiter 14. The telescopic cylinder 4 is driven to make the copper sheet pressing head 11 approach the copper sheet. The lifting cylinder 6 is started to drive the lifting plate 7 to drive the copper sheet pressing head 11 to press down the copper sheet, realizing the automatic pressing of the copper sheet;
[0020] On the surface of the lifting plate 7, there are two fine-tuning sliding tables 8. The fine-tuning sliding table 8 includes a sliding table main body 801, an X-direction adjusting bolt 802, a Y-direction adjusting bolt 803, a Z-direction adjusting bolt 804, and a fine-tuning block 805.

On the top of the sliding table main body 801, there is a Z-direction adjusting bolt 804. On the bottom of the sliding table main body 801, there is a fine-tuning block 805. The top end of the fine-tuning block 805 is inserted into the inside of the sliding table main body 801. A pressing head fixing seat 9 is arranged on the fine-tuning sliding table 8. The pressing head fixing seat 9 is installed on the fine-tuning block 805 through bolts. By rotating the X-direction adjusting bolt 802, the Y-direction adjusting bolt 803, and the Z-direction adjusting bolt 804, the fine-tuning block 805 is controlled to drive the copper sheet pressing head 11 on the pressing head fixing seat 9 to perform high-precision adjustment in the XYZ directions, greatly facilitating the operator to perform micro-distance adjustment and effectively saving the debugging time.
