Problems solved by technology
[0004] After the research and development is completed, it is put into the market. When it is used, it is reported that the weight is heavy, which increases the burden on the machine tool spindle and bearings, affects the stability of the machine tool and thus affects the processing accuracy of the product, and there are also shortcomings such as high precision and difficult processing of the main internal parts. It has made further optimization improvements

The present invention proposes a new type of chuck, which includes a housing and jaw assemblies uniformly distributed along the circumferential direction of the housing. Slide relative to the radial direction of the housing to adjust to the required clamping size and fix it through the jaw locking cover; the housing is provided with a control panel connected to the clamping drive device, and the jaw assembly is passed through the control panel Control it to achieve clamping or loosening on the above clamping dimensions. The overall weight of the present invention is greatly reduced, and the structure is simpler at the same time, which is convenient for assembly and processing, and greatly reduces the production cost. Compared with the existing hydraulic chuck, it has higher strength and clamping force, and can realize self-centering clamping and Eccentric clamping has a wide range of applications. Compared with the existing instrument lathe clamps, it has the advantages of a large range of clamping dimensions and no need to replace the clamps.
Description
technical field [0001] The invention relates to the field of clamping of machines such as numerical control machine tools, bench drills, vertical drills, milling machines, numerical control engraving and milling, and in particular to a novel chuck. Background technique [0002] Fixtures are used in mechanical lathes to clamp workpieces and then process them. The structure of the existing lathe clamps generally includes a jaw movable cover and a spiral disk. A through hole is arranged in the center of the jaw movable cover, and a walking rail connected with the through hole is arranged on the cover surface of the jaw movable cover. Claws are provided for sliding on the walking rail, and the back of the claws is provided with a helical tooth groove that cooperates with the helical disc. Through the rotation of the helical disc, the claws slide toward each other or relative to each other in the traveling rail to realize the clamping and uninstall. [0003] The applicant appli...
