[0023] The floating component 4 includes a sliding sleeve 41, the outer side of the sliding sleeve 41 is slidably connected to the inner side of the chuck body 1, the bottom of the sliding sleeve 41 is fixedly connected to the top of the pull rod 3, the outer side of the sliding sleeve 41 is slidably connected to the adjusting component 42, and both sides of the adjusting component 42 are fixedly connected to the arc plate 43. When in use, the pull rod 3 tightens the floating component 4, and the sliding sleeve 41 in the floating component 4 moves downward along the chuck body 1, the sliding sleeve 41 drives the adjusting component 42 and the arc plate 43 to move downward, the arc plate 43 drives the first clamping component 5 to move, and the sliding sleeve 41 drives the second clamping component 6 to move. The first clamping component 5 and the second clamping component 6 clamp the material. By setting the floating component 4, the first clamping component 5 and the second clamping component 6 are driven to clamp the material. The floating component 4 enhances the clamping accuracy of the material and reduces the scrap rate of the product.

[0024] The adjusting component 42 includes a sliding column 421, the inner side of the sliding column 421 is slidably connected to the outer side of the sliding sleeve 41, the two sides of the sliding column 421 are fixedly connected to the top of the arc plate 43, the top of the inner cavity of the sliding column 421 is fixedly connected with a sliding rod 422, a sliding groove 411 is opened in the wall of the sliding sleeve 41, the inner side of the sliding groove 411 is slidably connected to the outer side of the sliding rod 422, and the outer side of the sliding rod 422 is sleeved with a rebound spring 423. When in use, the arc plate 43 drives the first clamping component 5 to move, and the sliding sleeve 41 drives the second clamping component 6 to move. If there is a positioning error in the material, the first clamping component 5 clamps the material first, and the second clamping component 6 is still a certain distance away from the material.

At this time, the sliding sleeve 41 moves downward relative to the sliding column 421 under the drive of the pull rod 3, and the sliding rod 422 moves relative to the slide groove 411. The sliding rod 422 drives the rebound spring 423 to stretch, and the sliding sleeve 41 continues to drive the second clamping assembly 6 to approach the material until the second clamping assembly 6 fixes the material and the pull rod 3 stops moving. By setting the adjustment assembly 42, the second clamping assembly 6 can continue to move toward the material after the first clamping assembly 5 clamps the material, thereby further enhancing the clamping accuracy of the material and avoiding the dimensional error of the material itself, which affects the clamping of the material by the chuck.

The inner side of the circular groove 412 is threadedly connected with the outer side of the threaded rod 425. When in use, if the first clamping assembly 5 clamps the material and the second clamping assembly 6 is too far away from the material, the clamping force of the first clamping assembly 5 on the material will continue to increase during the process of the second clamping assembly 6 approaching the material. At this time, the adjusting rod 424 can be adjusted, and the adjusting rod 424 drives the threaded rod 425 to move upward along the circular groove 412, and the sliding column 421 drives the arc plate 43 to slide downward, and the arc plate 43 drives the first clamping assembly 5 away from the material, so that the clamping assembly clamps more accurately. By setting the adjusting assembly 42, the positions of the first clamping assembly 5 and the second clamping assembly 6 can be adjusted to facilitate the clamping of the material by the clamping assembly.

[0026] The first clamping assembly 5 includes a first lever 51, the outer side of the first lever 51 is rotatably connected to the outer side of the arc plate 43, and a first claw 52 is provided at one end of the first lever 51 away from the arc plate 43.

When in use, the first lever 51 is rotatably connected to the inner side of the chuck body 1 through a rotating rod, and the arc plate 43 drives the first lever 51 to rotate, and the first lever 51 drives the first claw 52 to approach the material. By setting the first clamping assembly 5, the material is clamped to prevent the material from moving, thereby accelerating the production efficiency of the product.

[0027] The second clamping assembly 6 includes a second lever 61, the outer side of the second lever 61 is rotatably connected to both sides of the sliding sleeve 41, and a second claw 62 is provided at one end of the second lever 61 away from the arc plate 43.

By setting the second clamping assembly 6, the first clamping assembly 5 is assisted to fix the material, avoid material deviation, and quickly fix the material.

[0028] Working principle:

[0029] When in use, the chuck body 1 is located at the center of the front end of the spindle 2, the material is placed on the top 7, the pull rod 3 drives the floating assembly 4 to move downward, the sliding sleeve 41 in the floating assembly 4 moves downward along the chuck body 1, the sliding sleeve 41 drives the adjustment assembly 42 and the arc plate 43 to move downward, the arc plate 43 drives the first lever 51 to rotate, the first lever 51 drives the first claw 52 to approach the material, the sliding sleeve 41 drives the second lever 61 to rotate, and the second lever 61 drives the second claw 62 to approach the material;

[0030] If there is a positioning error in the material, the first clamping assembly 5 clamps the material first, and the second clamping assembly 6 is still a certain distance away from the material. Since the first clamping assembly 5 is restricted by the material and cannot continue to move, at this time, the sliding sleeve 41 moves downward relative to the sliding column 421 under the drive of the pull rod 3, and the sliding rod 422 moves relative to the slide groove 411. The sliding rod 422 drives the rebound spring 423 to stretch, and the sliding sleeve 41 continues to drive the second clamping assembly 6 to approach the material until the second clamping assembly 6 fixes the material and the pull rod 3 stops moving;

[0031] If the second clamping assembly 6 is too far away from the material when the first clamping assembly 5 clamps the material, the adjusting rod 424 can be adjusted. The adjusting rod 424 drives the threaded rod 425 to move upward along the circular groove 412, and the sliding column 421 drives the arc plate 43 to slide downward. The arc plate 43 drives the first clamping assembly 5 away from the material, so that the clamping assembly can clamp more accurately.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
