Abstract

The invention discloses a clamping device for three-coordinate measurement of a workpiece, and belongs to the technical field of measurement. The clamping device comprises a body, a clamping component and an adjusting component, wherein the body is provided with a plurality of positioning pins; the clamping component comprises a plurality of clamping pieces, each clamping piece comprises an air cylinder, a lever and a pressing head, a piston rod of each air cylinder is hinged to one end of the corresponding lever, each air cylinder is provided with a first air port and a second air port which are communicated with two cavities of the air cylinder respectively, and the middle of each lever is rotationally installed on the corresponding air cylinder, and each pressing head is located at the other end of the corresponding lever; and the adjusting component comprises an air source, a pressure regulating valve and a three-position four-way directional control valve, and an air outlet of the air source is communicated with an air inlet of the pressure regulating valve. According to the clamping device for three-coordinate measurement of the workpiece, before three-coordinate measurement is conducted on the workpiece, different clamping forces generated when the workpiece is assembled can be simulated through the air cylinders, and therefore the assembly dimension of the workpiece can be accurately obtained.

Description

technical field [0001] The invention belongs to the technical field of measurement, and more specifically relates to a clamping device for three-coordinate measurement of a workpiece. Background technique [0002] In the field of die-casting, three-coordinate measurement is required before the workpiece leaves the factory, that is, the length, width, height, and hole distance of the workpiece are determined, and these are used as subsequent assembly dimensions to guide assembly. [0003] Usually, the three-coordinate measurement of the workpiece is: firstly, the positioning device is used to position the workpiece, and then the three-coordinate measurement is performed to determine the assembly size of the workpiece. [0004] However, some workpieces have large deformations before and after being clamped by bolts, and the deformations are also different under different clamping forces, which makes the three-coordinate measurement in the free state and the three-coordinate me...
