Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings.

[0010] like figure 1 As shown, the present invention includes a three-jaw chuck and claws, the claws are provided with a dovetail groove, and a dovetail fixture is fitted in the dovetail groove, and the dovetail inclination angle of the dovetail fixture is 20o-30o.

[0011] The claws are preferably made of flexible materials, which can shake with the workpiece so as to reduce the impact force on the workpiece.

[0012] The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods, as long as various insubstantial improvements are adopted in the method concept and technical solutions of the present invention, or there is no improvement Directly applying the concept and technical solutions of the present invention to other occas...

Abstract

The invention discloses a dovetail groove type clamping jaw. The dovetail groove type clamping jaw comprises a three-jaw chuck and a clamping jaw body and is characterized in that a dovetail groove is formed in the clamping jaw body, and a dovetail clamp is arranged in the dovetail groove in a matched manner; and the dovetail inclination angle of the dovetail clamp ranges from 20 degrees to 30 degrees. The dovetail groove type clamping jaw has the beneficial effects that the dovetail clamp is arranged on the clamping jaw body, and the dovetail clamp is connected with the clamping jaw through the dovetail groove, so that reliable clamping force is provided; the clamping jaw body is made of flexible materials, and is not prone to being damaged; and shaking in the process of machining a workpiece is relieved.

Description

technical field [0001] The present invention relates to engaging components, and more particularly to dovetail type claws. Background technique [0002] A chuck is a mechanical device used to clamp a workpiece on a machine tool. A machine tool accessory that clamps and positions workpieces by using the radial movement of movable jaws evenly distributed on the chuck body. The chuck is generally composed of three parts: the chuck body, the movable jaw and the jaw driving mechanism. The minimum diameter of the chuck body is 65mm, and the maximum can reach 1500mm. There is a through hole in the center to pass the workpiece or bar; the back has a cylindrical or short tapered structure, which is connected directly or through the flange to the end of the machine tool spindle. . Chucks are usually installed on lathes, cylindrical grinders and internal grinders, and can also be used with various indexing devices for milling machines and drilling machines. From the number of chuck...
