Abstract

The invention discloses workpiece locating and clamping equipment. The workpiece locating and clamping equipment comprises a shell, wherein an active drying mechanism is arranged in the shell, the workpiece locating and clamping equipment also comprises a slave driving mechanism driven by virtue of the active drying mechanism, and the slave driving mechanism drives a clamping mechanism to act; theactive drying mechanism comprises a cylinder, a driving rack driven by the cylinder and a driving gear meshed with the driving rack; the slave driving mechanism comprises a screw connected with the driving gear, and two sides of the screw are respectively meshed with a first driven gear and a second driven gear; the slave driving mechanism is arranged in a fixation frame, the screw runs through the fixation frame to be connected with the driving gear, and a left driving arm and a right driving arm which are respectively driven by the first driven gear and the second driven gear by virtue of the screw; and the cylinder drives the driving rack to drive the driving gear to move and drive the screw to rotate, so as to drive the left driving arm and the right driving arm to drive a left grabbing arm and a right grabbing arm, and the left grabbing arm and the right grabbing arm drive a left gripper and a right gripper to clamp or loosen.

Description

technical field [0001] The invention relates to a clamping device, in particular to a workpiece positioning and clamping device. Background technique [0002] In the process of workpiece processing, the workpiece needs to be clamped and fixed to ensure the stability of the workpiece during processing and improve the processing accuracy of the workpiece. Generally, a variety of fixed chucks and fixed fixtures are provided in the workpiece processing. [0003] However, during the processing of shaft workpieces, due to the arc-shaped forming surface, traditional fixed chucks or fixtures cannot achieve stable clamping of shaft workpieces, resulting in the workpiece being damaged due to loose clamping during processing. Problems such as rotation occur, which seriously affect the machining accuracy of the workpiece. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a workpiece positioning and clam...
