Abstract

The invention discloses a clamp for short-axis parts of numerically-controlled machine tools. The clamp comprises a fixing clamp, clamping jaws, a top ring and an air channel; a cylindrical fixing cavity is formed in the fixing clamp, one end of the fixing cavity is provided with an opening, and the other end is provided with a clamping end in a protruding mode along the axis; the multiple clamping jaws are arranged in the fixing cavity and are arranged in the circumferential direction of the fixing cavity at equal-angle intervals, and the clamping jaws can do translational motion in the radial direction of the fixing cavity; the top ring is coaxially arranged in the fixing cavity and located on the sides, away from the opening, of the clamping jaws, the outer ring wall of the top ring is fixedly connected with the inner wall of the fixing cavity, and the ends of the short-axis parts can abut against and be tightly attached to one side of the top ring; the air channel is formed in the side, away from the opening, of the fixing clamp and enables the fixing cavity to communicate with the outside. According to the clamp for the short-axis parts of the numerically-controlled machine tools, the ends of the short-axis parts can be positioned and clamped, the short-axis parts are pressed on the top ring through external air pressure, the clamping firmness of the short-axis parts is improved, the machining safety is guaranteed, and the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to a fixture for a short axis part of a numerical control machine tool. Background technique [0002] In the prior art, the commonly used fixture for clamping workpieces is the three-jaw self-centering chuck, which is mainly used for clamping shaft workpieces, but if it is a short-axis workpiece, it is placed in the chuck, and the contact between the jaws and the workpiece There should not be too many surfaces, otherwise the length of the workpiece will be too short to meet the turning requirements, and the workpiece will protrude too much, which will lead to unstable clamping. [0003] It should be noted that the above content belongs to the scope of the inventor's technical cognition and does not necessarily constitute the prior art. Contents of the invention [0004] In order to solve the above problems, the object of the present invention i...
