Problems solved by technology
[0004] One, since the clamping force of each jaw 14 is transmitted by the propulsion assembly 13, radial friction will be generated during the clamping process, and this radial friction will reduce the thrust of the propulsion assembly 13, resulting in clamping. The force of the clamping tools is lost in the radial friction force of each other, which reduces the maximum clamping force of the product;
[0005] Second, when each jaw 14 is fed, it will be restricted by the guide groove of the main body 10 at the same time, causing the guide seat 103 and the front sleeve 101 to generate inclined plane friction with each jaw 14, and this inclined plane friction will also reduce the propulsion assembly 13 The force of the clamping tool is lost on the friction of each other's inclined planes, which reduces the maximum clamping force of the product
[0006] The maximum clamping force of the above-mentioned products is the most critical effect of the chuck. If the clamping force is not enough to support the processing load of the tool, there will be problems of slipping and idling or the tool is stuck in the workpiece

Embodiment Construction
[0038] see figure 2 , 3 And 4, is to propose the preferred embodiment of chuck clamping force lifting structure of the present invention; It comprises a body 20, a feed shaft tube 30, a fixed ring 40, a propulsion assembly 50 and some jaws 60, wherein:
[0039] The body 20 is formed by combining and positioning the front cover 21, the rear cover 22 and the guide seat 23. The front cover 21 and the rear cover 22 are hollow components connected and fixed to each other, and the guide seat 23 is fixed in the front cover 21 The front cover 21 and the rear cover 22 are combined to form an axial space in the body 20, the end of the front cover 21 has an opening 211, and the guide seat 23 is matched with the front cover 21 to form a guide corresponding to the opening 211. A guide groove 24, the guide groove 24 has several inclined surfaces 241;
[0040] The feed shaft tube 30, corresponding to the guide seat 23 of the body 20, is rotatably pivoted at the rear end of the space in th...

The present invention relates to a structure for enhancing the clamping force of a collet. The structure comprises a body, a push component and holding jaws; the push component is mounted in the body and drives the holding jaws to open and close; a sliding layer is arranged on the corresponding contact surfaces among the holding jaws, the push component and the body; the sliding layer is made of a material of low friction coefficient; therefore, when the push component of the collect drive the plurality of holding jaws, the friction loss is reduced, and synchronously the interference friction drag between the plurality of holding jaws are reduced, so as to enable the clamping force of the collect to be applied completely on a clamped tool, and the holding jaws are not easy to be affected by the surface friction between the components, thereby enhancing the clamping force of the collect and preventing the tool from slipping.
Description
technical field [0001] The invention relates to a chuck clamping force lifting structure. Background technique [0002] Today's collet structure is mostly used in the positioning of rotary tools such as drills and milling cutters. Generally, the common collet structure uses screw feed components to push the jaws to connect and separate, and achieve the effect of clamping the rotary tool. Because The advantages and disadvantages of the aforementioned collet structure have a great influence on the tool processing effect, so many precision collets with different advantages have been developed on the market. Through the design of precision collets, the design of precision collets can assist users to stabilize the clamping tool and increase the accuracy of positioning. Therefore, The importance of various improved designs of related precision chucks for today's rotary processing machine tool market cannot be overstated. [0003] Currently common general existing technologies suc...
