The invention discloses a workpiece concentric clamping device with a centering calibration function and a centering calibrating method. The workpiece concentric clamping device comprises a lead screwfixed with a lead screw seat, wherein the lead screw is a forward and reverse lead screw, the left part of the lead screw is connected with the right part of the lead screw through a coupler, the coupler comprises two flange plates which are connected, and the two flange plates are connected by bolts; a first clamping part is connected with one side of the lead screw through a first nut; a firstmoving groove extends towards a clamping center point, and the first clamping part moves along the first moving groove; a guide rod is connected with the other side of the lead screw through a secondnut, and the guide rod is provided with two shifting rods with a center line included angle of 120 degrees; two second clamping parts are correspondingly connected with the end portions of the two shifting rods, and the two second clamping parts move along two second moving grooves correspondingly; and an included angle between the two second moving grooves and an included angle between each second moving groove and the first moving groove each are 120 degrees; and the distance between the first clamping part and the clamping center point is the same with the distance between the two second clamping parts and the clamping center point. The workpiece concentric clamping device has the effect of centering calibration.
Description
technical field [0001] This application is a divisional application of Chinese patent 2019109709942 (application date: 20191014, name: workpiece concentric clamping device and clamping method). [0002] The invention relates to the technical field of working and processing, in particular to a centering-calibrating workpiece concentric clamping device and a centering-calibration method. Background technique [0003] For the cleaning and processing of round castings (such as new energy motor housings), the workpiece needs to be clamped. The traditional method is to fix the three-jaw chuck, and the three jaws are manually tightened one by one. The centering is not high, and the clamping time Long, low production efficiency. Contents of the invention [0004] In order to overcome the above technical problems, the present invention provides a concentric clamping device for workpieces that can be centered and calibrated, driven by forward and reverse screw and guide rods, so th...
