During the rotation of the driving shaft 211, the second cam follower 520 is lifted or moved down by the second cam guide rail, so that the distance between the jacking component 500 and the turntable 220 is changed, and the jacking component 510 of the jacking component 500 is driven to move along the second cam guide rail to approach or move away from the battery welding position 221.

As a specific example, the jacking assembly 500 includes a first connection member 531, a second connection member 532, a jacking member 510 and a second cam follower 520, where the second cam follower 520 is disposed at the bottom of the second connection member 532 and slidably fitted with a second cam rail, one end of the second connection member 532 is connected to the jacking assembly 500, and the other end of the second connection member 532 is connected to the base plate 110, the working table 222 or other supporting structure via the first connection member 531, and the turret assembly 200 drives the turntable 220 and the connection disc 230 to rotate relative to the jacking assembly 500 by driving the rotation mechanism 210 thereof.

In one embodiment, the bottom of the turret assembly 200 is provided with a bottom plate 110, and the turret assembly 200 further includes a torsion limiter mounted at the bottom of the bottom plate 110 and connected to the second end of the drive shaft 211.

The torque limiter plays an overload protection role, and when the required torque exceeds a set value due to overload or mechanical failure, the turret assembly 200 may be jammed, and the torque limiter limits the torque transmitted by the driving shaft 211 in a slip manner until the driving of the driving shaft 211 is automatically restored after the overload condition disappears, so that the turret assembly 200 can be protected and stable operation of the apparatus is ensured.

The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
