A CNC machine tool machining center fixture

Abstract

The invention discloses a clamp of a numerical control machine tool machining center. The clamp of the numerical control machine tool machining center comprises a clamp rack, wherein a front-and-backthrough-arranged machining area is arranged in a top end surface of the clamp rack, a first clamping disc is rotationally matched with a right side wall of the machining area in a rotating mode, a first sliding cavity which extends leftwards and rightwards is arranged in a left side wall of the machining area, the tail end of the right side of the first sliding cavity communicates with the machining area, the first sliding cavity is in sliding fit connection with a first sliding block, a first inner cavity communicates with the tail end of the left side of the first sliding cavity, a second inner cavity communicates with the bottom of the first inner cavity, a second sliding cavity which extends towards the left side is formed in the upper side of the first sliding cavity, and a through sliding groove is formed between the second sliding cavity and the first sliding cavity in a penetrating mode. The clamp is simple in structure and simple in clamping step, the rapid dismounting and mounting of a workpiece is facilitated, the machining efficiency is greatly improved, the clamping stability is high, the machining precision is improved, and the production and development of enterprises are facilitated.

Description

technical field

[0001] The invention relates to the technical field of fixtures, in particular to a fixture of a CNC machine tool machining center. Background technique

[0002] CNC machine tool is a high-precision and high-efficiency automatic machine tool, equipped with multi-station turret or power turret, has a wide range of processing performance, and can process linear cylinders, oblique cylinders, arcs and various threads, grooves, Complex workpieces such as worms have various compensation functions such as linear interpolation and circular interpolation, and have played a good economic effect in the mass production of complex parts. For processing, the existing fixtures used for CNC machine tools have complicated clamping steps, are not easy to quickly disassemble and assemble, greatly affect the processing efficiency, and the clamping effect is poor, affecting the machining accuracy, which can easily lead to the scrapping of the workpiece, which is not conducive to ...
