An adjustable workpiece clamping device

Abstract

The invention relates to an adjustable workpiece clamping device. Due to the adjustable workpiece clamping device, fast clamping of a workpiece can be facilitated, and by adjusting the caliber of hooks, workpieces in different calibers can be clamped easily and conveniently. According to the technical scheme, a guide rail fixing plate and a cam rotating disk are included; and the cam rotating diskis arranged on the guide rail fixing plate and rotates through a center shaft. The adjustable workpiece clamping device is characterized in that three T-shaped groove guide rails are arranged betweenthe guide rail fixing plate and the cam rotating disk, and are uniformly distributed at the center of the guide rail fixing plate in the circumferential direction; the included angle is 120 degrees,and three semicircular slide grooves are uniformly formed in the cam rotating disk; one end of each slide groove is arranged at the position close to the center of the cam rotating disk; the other endof each slide groove is arranged at the edge position of the cam rotating disk, and a hot wheel shape is formed; hook assemblies capable of sliding are connected to the T-shaped groove guide rails and the slide grooves; the cam rotating disk is locked through a locking assembly; and the locking assembly is arranged at the round edge position of the cam rotating disk.

Description

technical field [0001] The invention relates to an adjustable workpiece clamping device. Background technique [0002] With the rapid development of automation technology, the application of automatic clamping fixtures is becoming more and more common, but the known clamping fixtures have defects such as slow clamping speed and complex structure. [0003] When the existing clamps clamp the workpiece, it is often necessary to change the caliber of the clamper according to the size of the caliber of the workpiece, which requires a clamper capable of adjusting the clamping caliber to realize its function. At present, among the known fixtures, there is a lathe chuck three-jaw system that adjusts the clamping caliber through gears. The lathe chuck three-jaw system uses three screws to fasten the chuck to the machine tool through the screw holes on the end surface of the disc body. on the flange. Insert the wrench into the square hole of any gear, when the wrench is turned, the ...
