Abstract

The invention relates to the field of machining machinery, in particular to a chuck device capable of adjusting the clamping strength and controlling the clamping jaw range. The chuck device comprisesa power source, a power transmission structure for power transmission, a clamping jaw structure and a frame, which are connected in sequence; and the clamping jaw structure is rotationally connectedto the frame. The chuck device further comprises an adjusting structure for adjusting the grabbing strength of the clamping jaw structure and finely adjusting the moving range of the clamping jaw structure; the adjusting structure is connected with the clamping jaw structure; and the power transmission structure comprises a connecting rod mechanism for realizing opening and closing motion trajectories of the clamping jaw structure. The chuck device is provided with the adjusting structure; the clamping jaw structure can adjust the clamping strength and finely adjust the moving range of the clamping jaw structure; meanwhile, the connecting rod mechanism is provided for controlling the opening and closing motion trajectories of the clamping jaw structure to realize adjustment of the moving range of the clamping jaw structure and adjustment of the clamping strength; and meanwhile, the clamping is convenient, the moving speed is adjustable, and the clamping effect is excellent.

Description

technical field [0001] In the field of processing machinery, the present invention relates more specifically to a collet device that can adjust the clamping force and control the range of the clamping jaws. Background technique [0002] In the manufacturing industry, many workpieces need to be clamped to meet a certain mechanical movement. In the prior art, the chuck device used for mechanical grasping has problems such as difficult adjustment of clamping force, fixed range of motion of the chuck, and composition Disadvantages such as complex structure of parts. For example, a chuck device is disclosed in the Chinese invention patent application No. CN201520817179.X, in which the structure of parts such as the first chuck and the second chuck is very complicated, and the process requirements are high, which brings great pressure to the processing and assembly of parts. There is a certain degree of difficulty, and the operation and adjustment are also complicated or difficul...
