The segmenter 2 and the clamping assemblies 4 as tooling are jointly driven to open and close by one driving motor, so that the action is more flexible and the efficiency is higher, and through timing setting, the two can be more adaptively matched.

[0028] Preferably, as Figure 5 And 6The clamping assembly 4 comprises a base plate 8, a centering opening and closing block 9, two centering connecting rods 10, a first clamping block 11 and a second clamping block 12. The base plate 8 is mounted on the rotary disc 3. The centering opening and closing block 9 is slidably connected to the base plate 8 by a slide rail. The centering opening and closing block 9 can move in the radial direction of the rotary disc 3. The first clamping block 11 and the second clamping block 12 are slidably connected to the base plate 8 by slide rails. In this embodiment, the moving directions of the first clamping block 11 and the second clamping block 12 are perpendicular to the moving direction of the centering opening and closing block 9.

One end of the two connecting ends is connected to the centering opening and closing block 9 by a first follower bearing 14. The other end is used to drive the first clamping block 11 and the second clamping block 12. The centering connecting rod 10 is used as a transmission to drive the two clamping blocks when the centering opening and closing block 9 moves.

Wherein, one end of the transmission shaft 20 penetrates the output shaft of the divider 2 and is connected with the opening and closing cam 21, and the other end is drivingly connected with the second transmission part 7. Preferably, the swing cam disc 23 is configured as a disc structure provided with a cam track groove, and the end of the swing lever 22 is adapted with the track groove through a bearing, when the driving shaft of the driving motor drives the swing cam disc 23 to rotate, it can drive the swing lever 22 to swing back and forth, and in turn the other end of the swing lever 22 can also drive the swing disc 24 to swing back and forth, the swing disc 24 drives the transmission shaft 20 to rotate, and in turn drives the opening and closing cam 21 to swing, and finally the opening and closing cam 21 is driven to move up and down by the third follow-up bearing 16, so that the clamping end is opened and closed. In the embodiment, the clamping assembly 4 is provided with four groups, and adjacent clamping assemblies 4 are spaced apart by 90°, and the opening and closing cam 21 is located between the feeding position a and the discharging position b, when the clamping assembly is located at the feeding position a, the driving part drives the clamping end to open and feed, and then the driving part returns, the clamping end of the feeding position a clamps the material and rotates with the turntable 3 to the next working position, at the same time, before the turntable 3 rotates, the returned driving part rotates and drives the clamping end of the clamping assembly 4 at the discharging position b to open and discharge, and then the turntable 3 rotates to move to the feeding position a. In this way, the feeding and discharging positions b are opened and closed, and the working position is clamped, and the tool opening and closing is perfectly switched during the rotary division. In this way, by driving the clamping assembly and the divider by the same driving source, the clamping assembly and the divider are cooperatively linked, and different numbers of clamping assemblies are cooperatively linked by different division ratios of the dividers on the market, so that the tool opening and closing is perfectly switched during the rotary division of the divider, and the automation is more accurate.
