Abstract

The invention relates to a radial measuring instrument of hydraulic drive rotator, and the radial measuring instrument comprises a base, a hydraulic cylinder body arranged at the upper part of the base, and a piston rod which is arranged on a piston matching with the hydraulic cylinder body, wherein, the piston rod has a rack. The hydraulic cylinder body is respectively provided with an A oil opening and a B oil opening which are mutually communicated with an inner cavity and the electromagnetic valve; the rack arranged on the piston rod is meshed with the gear on a gear rod; the two ends of the gear rod are rotatablely arranged in a shell through bearings respectively; the shell is fixed with the base; one end of the gear rod extends outwards and is fixed and connected with a connecting block through a pin shaft; the connecting block is fixed and connected with the radial measuring instrument body through a rotating arm. The hydraulic drive part of the invention converts the straight line movement of the piston rod into the rotation of the gear so as to drive the radial measuring instrument rigidly connected with the rotating arm to enter or exit the measuring area on the workpiece, thereby finishing the checking of the diameter of the multi-station workpiece and the alternation of the workpiece. The device has simple structure and the production cost is just one tenth of the cost of the hydraulic motor; the device has big drive force and big torque, thereby overcoming the defect that the similar measuring instruments in Japan can not be driven caused by the weight of the measuring instruments.

Description

technical field [0001] The invention relates to a radial measuring instrument, which is specifically installed on a cylindrical grinding production line, and a hydraulic linear oil cylinder with a rack is used to drive the rotary arm to rotate, so that the radial measuring instrument with claw telescopic function can complete multi-station grinding The detection of the diameter of the workpiece or the work of moving the gauge away from the work area to replace the workpiece. Background technique [0002] When measuring the diameter of the outer circle of the workpiece online on the cylindrical grinding production line, an automatic radial gauge placed on the workbench is generally used. During grinding, it enters the grinding area for measurement, and exits the grinding area after measurement. Obviously, it can only be located directly in front of the grinding wheel, which often causes inconvenience to the workpiece installation. Especially when multiple shaft diameters are...
