[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Embodiment one

[0025] Reference Figs. 1-3 A clamping type clamp of a tapping machine, comprising:

[0026] The bottom plate 1;

[0027] The mounting plate 2 is fixedly installed on one side of the bottom plate 1;

[0028] The mounting seat 3 is fixedly installed on the top of the bottom plate 1.

[0029] The clamping mechanism is arranged on the top of the bottom plate 1 and is used for clamping the nut. One side of the mounting seat 3 is fixedly installed with the air cylinder 4. The output shaft of the air cylinder 4 is fixedly connected with the top block 5. The bottom plate 1 is rotatably installed with the two symmetrical clamping arms 6. The two clamping arms 6 are both fixedly installed with the chuck 10. The two clamping arms 6 are both fixedly connected with the protruding block 7. The two protruding blocks 7 are matched with the top block 5. The clamping mechanism comprises the top column 11 which is slidably installed on the bottom plate 1 and is matched with the top block 5. The two clamping arms 6 are both fixedly installed with the fixed rod 8. The two fixed rods 8 are connected with the same tension spring 9. The two extrusion blocks 13 are both fixedly connected with the compression spring 12. One end of the two compression springs 12 is respectively fixedly connected with the inner wall of one side of the sliding slot. One side of the top column 11 is provided with the two symmetrical sliding slots. The two sliding slots are both slidably installed with the extrusion block 13. One side of the two extrusion blocks 13 is fixedly connected with the rubber pad 14.

[0030] The implementation principle of the clamping type clamp of the tapping machine in the embodiment of the application is as follows: in use, the nut falls between the top column 11 and the two chucks 10 through the blanking machine. Then the air cylinder 4 is started. The air cylinder 4 drives the top block 5 to move horizontally. The top block 5 drives the top column 11 to move horizontally. The top column 11 drives the two extrusion blocks 13 to move horizontally. The two extrusion blocks 13 are matched with the two chucks 10 and can clamp the front and back surfaces of the nut. Through the arrangement of the two compression springs 12 and the two rubber pads 14, the damage of the nut caused by impact hard contact can be effectively avoided. At the same time, the top block 5 is matched with the two protruding blocks 7 and can drive the two clamping arms 6 to rotate. The two clamping arms 6 respectively drive the two chucks 10 to move close to each other. Then the two chucks 10 can clamp the side surface of the nut. Thus the stability of clamping can be effectively improved. When the air cylinder 4 is started again, the air cylinder 4 drives the top block 5 to move horizontally. Then the top column 11 can release the nut. At the same time, the tension spring 9 drives the two clamping arms 6 to reset through the deformation force. Then the two chucks 10 can release the clamping of the nut.

[0031] Embodiment two

[0032] The difference between the embodiment and the embodiment one is that the mounting plate 2 is fixedly installed with the rotary motor. The output shaft of the rotary motor is fixedly connected with the bottom plate 1. When the rotary motor is started, the rotary motor drives the bottom plate 1 to overturn. Thus the automatic unloading can be realized.

[0033] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
