[0019] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0020] Please refer to Figures 1 to 4 The utility model discloses a machine tool screw quick clamping platform 100, which includes an assembly platform 1, a top block 2, a clamping block 3 and a driving handle assembly 4. The assembly platform 1 is a horizontal platform structure, the top block 2 is installed on one side of the assembly platform 1, and the clamping block 3 is slidably arranged on the assembly platform 1. A clamping area 5 is formed between the clamping block 3 and the top block 2. The clamping inner wall 31 of the clamping block 3 matches the nut 20 of the screw 10. The driving handle assembly 4 is installed on the side of the clamping block 3 away from the top block 2. The clamping block 3 moves under the drive of the driving handle assembly 4 to increase or decrease the clamping area 5. When the clamping area 5 is reduced, the screw 10 can be quickly positioned. The clamping inner wall 31 of the clamping block 3 matches the nut 20 of the screw 10. With the movement of the clamping block 3, it is only necessary to place the nut 20 of the screw 10 into the clamping area 5. The screw 10 can be quickly positioned by shrinking the clamping area 5. At the same time, the way the driving handle assembly 4 is pulled makes the positioning operation very simple and convenient. More specifically, as follows:

[0021] Please refer to Figures 1 to 4 The clamping block 3 includes a transverse connecting block 33, a left limiting block 34, and a right limiting block 35. The transverse connecting block 33, the left limiting block 34, and the right limiting block 35 are elongated rod-shaped structures. The left limiting block 34 is connected to one end of the transverse connecting block 33 and is perpendicular to the transverse connecting block 33. The right limiting block 35 is connected to the other end of the transverse connecting block 33 and is perpendicular to the transverse connecting block 33. Specifically, the clamping inner wall 31 formed by the transverse connecting block 33, the left limiting block 34, and the right limiting block 35 matches the nut 20 of the screw 10.

[0022] Please refer to Figures 1 to 4, the driving handle assembly 4 includes a connecting member 41, an intermediate connecting rod 42, and a pulling handle 43. The pulling handle 43 is rotatably mounted on the assembly platform 1. One end of the intermediate connecting rod 42 is pivotally connected to the pulling handle 43, and the other end of the intermediate connecting rod 42 is connected to the connecting member 41. The connecting member 41 is connected to the clamping block 3. When the pulling handle 43 rotates relative to the assembly platform 1, the intermediate connecting rod 42 has an extended position and a retracted position. By moving the intermediate connecting rod 42 between the extended position and the retracted position, the connecting member 41 and the clamping block 3 are moved in conjunction. When the intermediate connecting rod 42 is in the extended position, the clamping block 3 clamps the screw 10. When the intermediate connecting rod 42 is in the retracted position, the clamping block 3 loosens the screw 10. Specifically, the pulling handle 43 includes a rotating handle 431 and a connecting rod 432. One end of the rotating handle 431 is pivotally connected to the assembly platform 1, the other end of the rotating handle 431 is pivotally connected to one end of the connecting rod 432, and the other end of the connecting rod 432 is pivotally connected to the intermediate connecting rod 42. The rotating handle 431, the intermediate connecting rod 42, and the connecting rod 432 together form a linkage mechanism.

[0023] Please refer to Figures 3 to 4 , the clamping block 3 is provided with a engaging portion 32 corresponding to the connecting member 41, and the connecting member 41 is engaged with the engaging portion 32, so that the assembly between the components is more compact.

[0024] Please refer to Figure 1 , the screw quick clamping platform 100 for machine tools further includes a guiding component 6. The guiding component 6 includes a slider 61 and a slide rail 62. The slide rail 62 is mounted on the assembly platform 1, and the slider 61 is connected to the clamping block 3. The slider 61 is slidably disposed on the slide rail 62, so that the slider 61 moves more smoothly relative to the slide rail 62.

[0025] Please refer to Figures 1 to 4 , a connecting platform 433 is provided at the bottom of the rotating handle 431, and the rotating handle 431 is detachably connected to the assembly platform 1 through the connecting platform 433.

[0026] Please refer to Please refer to Figures 1 to 4 , the working process of the screw quick clamping platform 100 for machine tools of the present utility model:

[0027] Put the nut 20 of the screw 10 into the clamping area 5, pull the rotating handle 431 and swing the connecting rod 432 in conjunction, so as to drive the intermediate connecting rod 42 to move from the retracted position to the extended position. The clamping block 3 approaches the nut 20 of the screw 10. As it continuously approaches, the left limiting block 34 and the right limiting block 35 clamp both sides of the screw 10 and push. The transverse connecting block 33 pushes the bottom end surface of the nut 20 of the screw 10 and finally abuts against the abutting block 2, and the screw 10 is finally positioned. When it needs to be loosened, pull the rotating handle 431 again and swing the connecting rod 432 in conjunction, so as to drive the intermediate connecting rod 42 to move from the extended position to the retracted position.

[0028] By combining the assembly platform 1, the abutting block 2, the clamping block 3, the driving handle assembly 4, etc., the abutting block 2 is installed on one side of the assembly platform 1, the clamping block 3 is slidably arranged on the assembly platform 1, a clamping area 5 is formed between the clamping block 3 and the abutting block 2, the clamping inner wall 31 of the clamping block 3 matches the nut 20 of the screw 10, and the driving handle assembly 4 is installed on the side of the clamping block 3 away from the abutting block 2. The clamping block 3 moves under the drive of the driving handle assembly 4 to increase or decrease the clamping area 5. A major feature of the present utility model is that the clamping inner wall 31 of the clamping block 3 matches the nut 20 of the screw 10. Coupled with the movement of the clamping block 3, only by placing the nut 20 of the screw 10 into the clamping area 5, the screw 10 can be quickly positioned by reducing the clamping area 5. At the same time, the way of pulling the driving handle assembly 4 makes the positioning operation very simple and convenient. In addition, the screw quick clamping platform 100 for machine tools of the present utility model has the advantage of simple structure.
