Description

Technical Field

[0001] The present application relates to the technical field of chucks, and in particular to an openable and closable chuck. Background Art

[0002] A chuck is a device used to fix the workpiece during the mechanical manufacturing process so that it occupies the correct position for construction or inspection. When machining a workpiece on a machine tool, in order to ensure that the surface of the workpiece meets the technical requirements of size, geometry, and relative position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before machining.

[0003] Most existing chucks use relatively complex mechanical mechanisms to drive when clamping. After a period of use, they are more likely to be damaged. Moreover, excessive use of mechanical mechanisms makes installation and disassembly more troublesome. Therefore, a chuck that can be opened and closed is needed. Summary of the Invention

[0004] The purpose of this application is to provide an openable and closable chuck to solve the problems raised in the background technology.

[0005] An embodiment of the present application provides an openable and closable chuck, comprising an elliptical tube, a rotating shaft head being provided on the elliptical tube, a washer being provided on the rotating shaft head, a restraining ring being fixedly mounted on the washer, and a chuck being slidably mounted on the restraining ring.

[0006] By adopting the above technical solution, an elliptical tube, a rotating shaft head, a washer, a restraining ring and a chuck are arranged and installed together. The chuck can be opened and closed by rotating the elliptical tube, which is very convenient to install and use.

[0007] Optionally, a mounting block is fixedly mounted on the rotating shaft head, an inner liner is provided in the mounting block, and the inner liner can be fixedly mounted on the elliptical tube.

[0008] By adopting the above technical solution, the rotating shaft head can be fixed on the elliptical tube through the mounting block, so that the rotating shaft head can be driven to rotate when the elliptical tube is rotated.

[0009] Optionally, the restraining ring is elliptical in shape, an elliptical through groove is provided on the restraining ring, and a limiting groove is provided on the restraining ring next to the through groove.

[0010] By adopting the above technical solution, the reinforcement ribs on the outside of the chuck cooperate with the limiting groove in the constraint ring so that the chuck can only move along the direction of the limiting groove.

[0011] Optionally, the chuck includes a splint, a round pile is fixedly mounted on the splint, an elliptical groove is provided on the round pile, and reinforcing ribs are provided on the splint, and the reinforcing ribs are slidably mounted in the limiting grooves on the constraint ring.

[0012] By adopting the above technical solution, when the elliptical shaft head rotates, it will squeeze the elliptical groove on the round pile on the chuck, thereby pushing the upper and lower chucks apart.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The technical solution of the present application is to set up an elliptical rotating shaft head, which will squeeze the elliptical groove on the round pile on the chuck after rotation, thereby pushing the upper and lower chucks apart, making it easier to open the chuck. By setting up an elliptical tube with the same short axis length of the inner wall as the diameter of the round pile at the tail of the chuck, when the elliptical tube is rotated to a vertical position, the two chucks can be opened. When the elliptical tube is rotated to a horizontal position, the inner wall of the elliptical tube will squeeze the round pile on the chuck, pushing the two chucks inward to close them, making it more convenient to use. The various structures cooperate with each other, saving time and being more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 1-7 The present application provides a technical solution: an openable and closable chuck, comprising an elliptical tube 1, a rotating shaft head 2 being provided on the elliptical tube 1, a washer 3 being provided on the rotating shaft head 2, a constraint ring 4 being fixedly mounted on the washer 3, and a chuck 5 being slidably mounted on the constraint ring 4. By setting the elliptical tube 1, the rotating shaft head 2, the washer 3, the constraint ring 4 and the chuck 5, several components are installed together, and the chuck 5 can be opened and closed by rotating the elliptical tube 1, which is very convenient to install and use.

[0025] In the technical solution of this application, if Figure 2 As shown, a mounting block 6 is fixedly mounted on the rotating shaft head 2, and an inner liner is opened in the mounting block 6. The inner liner can be fixedly mounted on the elliptical tube 1. The rotating shaft head 2 can be fixed on the elliptical tube 1 by the mounting block 6, so that the rotating shaft head 2 can be driven to rotate when the elliptical tube 1 is rotated.

[0026] In the technical solution of this application, if Figure 2 As shown, the shape of the constraint ring 4 is elliptical, and an elliptical through groove is provided on the constraint ring 4. A limiting groove 7 is provided on the constraint ring 4 next to the through groove. The reinforcing rib 9 on the outside of the chuck 5 cooperates with the limiting groove 7 in the constraint ring 4 so that the chuck 5 can only move along the direction of the limiting groove 7.

[0027] In the technical solution of this application, if Figure 2 As shown, the chuck 5 includes a splint 8, on which a round pile 10 is fixedly mounted, and an elliptical groove is provided on the round pile 10. The splint 8 is provided with a reinforcing rib 9, and the reinforcing rib 9 is slidably mounted in the limiting groove 7 on the constraint ring 4. When the elliptical shaft head rotates, the elliptical groove on the round pile 10 on the chuck 5 will be squeezed, thereby pushing the upper and lower chucks 5 apart.

[0028] When the chuck 5 needs to be closed, the chuck 5 is rotated in the opposite direction so that its long axis rotates to the horizontal position. The inner wall of the chuck 1 will squeeze the round pile 10 on the chuck 5, pushing the two chucks 5 inward to close it.
