Abstract

The invention belongs to the technical field of clamps. A CNC (computer numerical control) machine tool clamp comprises a bottom plate, a first sliding groove is formed in the top of the bottom plate, two symmetrically distributed first sliding blocks are connected to the interior of the first sliding groove in a sliding mode, a screw is rotationally connected between the inner walls of the two sides of the first sliding groove through a bearing, the screw is in threaded connection with the first sliding groove, a mounting plate is fixed to the tops of the first sliding blocks through bolts, a positioning groove is formed in the inner side of the mounting plate, the section of the positioning groove is arranged to be a right trapezoid, a second sliding groove is formed in the inner wall of the bottom of the positioning groove, a second sliding block is connected to the interior of the second sliding groove in a sliding mode, a fixing block is fixed to the top of the second sliding block through a bolt, a clamping plate is hinged to the inner side of the fixing block, a transmission mechanism and a return mechanism are arranged on the mounting plate, and a front pressing mechanism and a rear pressing mechanism are arranged on the bottom plate. According to the CNC machine tool clamp, the screw is rotated to drive the mounting plate and the clamping plate to synchronously move; and when the clamping plate gradually makes contact with a plate, the clamping plate can rotate to gradually form an angle parallel to the bevel edge of the plate till the plate is attached and clamped.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a CNC numerical control machine tool fixture. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or inspection. It is also called fixture. In a broad sense, any process in the process is used to quickly and The device that installs the workpiece conveniently and safely can be called a fixture. CNC machine tool (numerical control machine tool) is an automatic machine tool equipped with a program control system, which can make the machine tool move and process parts according to the programmed program. CNC machine tools integrate machinery, automation, computer, microelectronics and other technologies to solve the processing problems of complex, precise and small batch parts. It is a flexible and high-efficiency automatic machine to...
