Machine tool clamp

Abstract

The utility model relates to machine tool accessories, in particular to a machine tool clamp which is mainly suitable for a transparent machine tool chuck of a double-station machine tool, is cylindrical and is formed by connecting two sections in a threaded connection or clamping connection mode, the outer edges of the two end portions are in a horn mouth shape, and the outer edges of the two end portions are in a horn mouth shape. The horn-mouth-shaped part is divided into a plurality of surrounding type clamping jaws by a plurality of axial gaps which are equally divided in the circumferential direction. Due to the fact that the two ends of the cylindrical clamp are each provided with one set of clamping jaw, the clamping area of a double-station workpiece can be increased, clamping is firmer, and the cylindrical clamp can be well matched with a double-station machining lathe.

Description

TECHNICAL FIELD

[0001] The utility model claims the priority of our company's patent application 2022105223918 "double-station lathe use permeability rotating chuck". It relates to machine tool accessories, in particular to a machine tool clamp, mainly suitable for the permeability machine tool chuck of double-station machine tool. BACKGROUND

[0002] The ordinary machine tool clamp is basically cylindrical or flared, and its root is fixed in the inner cavity of the annular chuck, and a plurality of annular clamping jaws are extended from the root to the front end, and the clamping jaws are clamped to the workpiece by the pneumatic components in the chuck. Our company has developed a double-station machining machine tool, and the chuck is a permeable annular chuck, and the left and right sides of the chuck are provided with machining positions. Only the ordinary clamping jaw clamp is difficult to clamp the workpiece firmly due to the small contact surface. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at overcoming the defects of the prior art, and provides a machine tool clamp which can be quickly assembled and matched with the double-station lathe use permeability rotating chuck, so that the double-station workpiece clamping is more reliable.

[0004] The technical scheme of the utility model is as follows: a machine tool clamp is cylindrical, and the inner cavity is a clamping working surface. The clamp is connected by two sections, and the connection mode is one of screw connection or clamping connection. The outer edges of the two end portions are flared, and the flared portions are divided into a plurality of clamping jaws by a plurality of circumferentially divided axial slits.

[0005] Specifically, the connection mode is screw connection, one section of the connection end portion is provided with an external thread, and the other section of the connection end portion is provided with a corresponding internal thread; during assembly, the two sections are screwed together and embedded in the cavity of the permeable machine tool chuck.

[0006] In order to make the assembly faster and simpler, the roots of the two sections of the clamp can be designed as clamping jaw type connection mode, and connected together by clamping connection.

[0007] Because the cylindrical clamp of the design has a set of clamping jaws at each end, the clamping area of the double-station workpiece can be increased, and the clamping is more reliable, which can be well matched with our double-station machining lathe. BRIEF DESCRIPTION OF DRAWINGS

[0013] Further illustrated below in combination with the drawings.

[0014] Example one: a machine tool clamp, in the form of a cylinder, with embracing clamping jaws 4, the clamp is composed of two sections, one end of each section is a root, from the root to the other end extends a plurality of embracing clamping jaws 4, a gap 2 is provided between adjacent clamping jaws 4 for the clamping jaws to deformably extend and retract, the root of one section is provided with an external thread 1, and the root of the other section is provided with a corresponding internal thread; when assembled, the roots of the two sections are screwed together and embedded in a through machine tool chuck cavity.

[0015] Example two: different from example one, the connection mode of the roots of the two sections is changed to a snap fastening mode.
