Problems solved by technology

[0004] During the workpiece clamping process, the traditional three-jaw and four-jaw chucks can only clamp the outer diameter of the workpiece or the mouth of the projectile body, but cannot clamp the inner bore of the projectile workpiece
Due to the large deviation of the rough workpiece mouth and the outer diameter of the workpiece, the length is inconsistent, which has a great impact on the clamping accuracy of the workpiece after clamping

Embodiment Construction

[0017] The working principle and content of the invention will be further described below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, a clamp for clamping the inner chamber of the projectile according to the present invention mainly includes three major components, a supporting part, a clamping part and a transmission part.

[0019] Support part: mainly includes 1, positioning body 2, body 11, standard parts screws

[0020] 14. Standard screw, one end of the supporting part is connected to the flange of the machine tool, and the other end supports the projectile, which is used to connect the projectile and the machine tool.

[0021] (1) The positioning body 1 is installed on the front end of the main body 2 through screwing threads, and is in contact with the bottom shape of the inner chamber of the projectile, and is connected with the fixture body through the standard fastening screw to play the role of supporting the projectile body and ...

Abstract

The invention provides a clamp for clamping an inner chamber of a projectile body, which belongs to the technical field of special clamping for projectile bodies and mainly comprises a supporting part, a clamping part and a supporting transmission part. The supporting part is installed on machine tool equipment through screws, the clamping part and the supporting transmission part are installed on the supporting part and inside the supporting part, the transmission part is connected with a machine tool oil cylinder to achieve front-back pulling actions to complete loosening and clamping of the clamping part, and clamping of the tool is achieved. And the structure is simple, the universality is good, the precision is high, and the consistency of product quality machining is improved. And finally, the function of machining and clamping the workpiece is achieved.

Description

technical field [0001] The invention belongs to the technical field of special clamping for projectiles, and relates to a special clamp for projectiles. Background technique [0002] When the projectile blank is being machined, the traditional three-jaw and four-claw chucks can only clamp and position the outer diameter of the projectile or the mouth of the projectile. Affected by the structure of the projectile, its clamping positioning accuracy and clamping flexibility There are large errors, which have a great impact on the production and processing of products and product quality. [0003] Disadvantages of traditional technology: [0004] During the workpiece clamping process, the traditional three-jaw and four-jaw chucks can only clamp the outer diameter of the workpiece or the mouth of the projectile body, but cannot clamp the inner bore of the projectile workpiece. Due to the large deviation of the rough workpiece mouth and the outer diameter of the workpiece, the l...
