The flat end face is provided with a plurality of first tool blocks 200 and second tool blocks 300 distributed at intervals, the first tool blocks 200 are fixedly connected with the base 100, specifically, the outer side of the bottom of the first tool block 200 is provided with a mounting plate 201, which is detachably connected with the base 100 through bolts. The second tool block 300 can reciprocate transversely on the base 100 to achieve clamping and positioning of the cylindrical battery.

[0033] Further, the adjacent sides of the first tool block 200 and the second tool block 300 are respectively provided with five first positioning grooves 210 and second positioning grooves 310 arranged linearly in the transverse (front-rear) direction, the cross-sectional profile of each first positioning groove 210 and second positioning groove 310 is a semicircular groove hole structure, and the first positioning groove 210 and the second positioning groove 310 can be combined to form a clamping cavity structure of the cylindrical battery, thereby achieving accurate positioning and clamping of the battery cell.

[0034] In order to realize the reciprocating transverse movement of the second tool block 300, the utility model adopts a clamping driving part 600 as a power source. The clamping driving part 600 is connected with the second tool block 300 through a transmission mechanism and can drive the second tool block 300 to move towards or away from the first tool block 200. At the same time, in order to ensure the stability and accuracy of the second tool block 300 during movement, the utility model also sets a limiting guide structure between the second tool block 300 and the base 100.

[0035] Specifically, the second tool block 300 is connected with a transmission block 400, the transmission block 400 is in an L-shaped structure, the vertical segments at the top of the two transmission blocks 400 are connected to the front and rear side walls of the second tool block 300, and the horizontal segments at the bottom of the transmission blocks 400 are attached to the bottom end face of the base 100, which makes the connection between the second tool block 300 and the base 100 stable and reliable.

In combination with the simple attachment between the horizontal end face at the top of the base 100 and the bottom of the second tool block 300, a simple and reliable clamping movement mechanism is formed. In this embodiment, the clamping driving part is a pneumatic cylinder, the main body of the pneumatic cylinder is fixedly arranged on the bottom end face of the base 100, and the telescopic rod of the pneumatic cylinder is connected with the linkage plate 500.

[0036] Meanwhile, in order to ensure the stability and accuracy of the second tool block 300 during movement, the utility model also sets up the limit guide structure between the second tool block 300 and the base 100.
