Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the mechanism includes a horizontal mounting plate 1, the mounting plate 1 is mounted on a center of revolution 2 (only a part of the structure of which is shown in the drawings), and the mounting plate 1 can horizontally rotate with the operation of the center of revolution 2. Wherein, a stepping motor 3, a belt wheel 4, a photoelectric switch 5 and other structures are arranged above the mounting base plate 1, and two chuck handles 7, two external thread bearings 8 and a limiting block 9 are arranged below the mounting base plate 1.

The stepper motor 3 is arranged on the mounting base plate 1 through a hollow mounting frame 13, and the bottom end of the rotor of the stepper motor extends downwards and is positioned in the hollow part of the mounting frame 13; and the belt wheel 4 is horizontally arranged and is in transmission connection with the bottom end of the rotor of the stepping motor 3 through a belt 12. Thus, when the stepping motor 3 is operated, the belt 12 can drive the belt pulley 4 to rotate around the center axis of the stepping motor.

A vertical switch board 14 is mounted on the side of the mounting frame 13, and the photoelectric switch 5 is mounted on top of the switch board 14. The top end of the rotor of the stepper motor 3 is connected with a horizontal photoelectric baffle 6, and when the photoelectric switch 5 is approximately frame-shaped and the opening faces the photoelectric baffle 6, the photoelectric baffle 6 can rotate into an inner frame at the position of the photoelectric switch 5 to form shielding for the photoelectric switch 5 when the stepper motor 3 operates, so that the opening and closing of a circuit are controlled.

Below the mounting base plate 1, two collet handles 7 are arranged in a cross-scissor arrangement. The external thread bearing 8 and the limiting block 9 are arranged between one ends of the two chuck handles 7 in parallel. The two external thread bearings 8 are connected with the belt pulley 4 through the same rotating shaft 10, and when the belt pulley 4 rotates, the two external thread bearings 8 can be driven to rotate and prop against the two chuck handles 7 to enable the two chuck handles to relatively move outwards; and when the two clamp handles 7 move inwards relatively, the two clamp handles are limited by the limiting block 9.

And a clamping jaw 11 is arranged at the other end of the two clamping head handles 7 far away from the external thread bearing 8 and the limiting block 9. Wherein, the tops of the two clamping jaws 11 are both connected on the mounting base plate 1 in a sliding manner, and the bottoms are connected through a spring 17.

Preferably, a slider 15 is provided at the bottom of the end of the mounting base plate 1, and the tops of both jaws 11 are formed with horizontally extending guide rails 16, and the slider 15 is mounted on each guide rail 16 and is slidable.

When the cup clamping mechanism is used for clamping a reaction cup, the stepping motor 3 operates to drive the belt pulley 4 and the two externally threaded bearings 8 to rotate, so that the two chuck handles 7 are propped against to move outwards relatively, the two clamping jaws 11 can be slid and folded to clamp the reaction cup, and meanwhile, the springs 17 are compressed.

When the reaction cup is required to be loosened, the stepping motor 3 continues to operate, and through the continuous rotation of the external thread bearing 8 and the action of the spring 17, when the two chuck handles 7 move relatively inwards, the two chuck handles are limited and stop moving until the chuck handles touch the limiting block 9, the two clamping jaws 11 can slide and move relatively far away, and the reaction cup can be loosened.

Wherein, in the process of clamping and loosening the reaction cup, the switch plate 14 is used for shielding the photoelectric switch 5 as the original point position of the clamping jaw 11, and the opening and clamping of the clamping jaw 11 are controlled by the step number of the stepping motor 3.

What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
