Embodiment Construction

[0009] Now further describe the technical solution of the present invention in conjunction with the accompanying drawings and embodiments.

[0010] Such as figure 1 The structure of the automatic detection CNC spherical grinding machine shown includes a base 1, a bed body 2, a feeding mechanism, a workpiece clamping mechanism, a grinding head mechanism 3, a hydraulic system, and a numerical control system. The feeding mechanism adopts a cross-sliding saddle structure. The upper sliding plate 4 carries the workpiece clamping mechanism for X-direction movement to complete the alignment between the center of the ball and the center of the grinding head spindle. The sliding saddle 5 carries the upper sliding plate 4 for Z-direction movement to complete the feed movement of the workpiece. . The movement of the X and Z axes of the machine tool is realized by AC servo motors driving precision ball screw pairs. The workpiece clamping mechanism includes a headstock mechanism 6 and a ...

Abstract

A numerally controlled spherical grinding machine with automatic measuring function is composed of base, main body, feeding unit, workpiece holding unit, grinding head unit, hydraulic system, and numeral control system. It features that its automatic measuring unit consisting of detecting element, detecting arm, drive cylinder and signal transmission unit is used for measuring the sizes of workpiece and controlling the feeding unit.

Description

technical field [0001] The invention relates to a grinding device for a sphere, in particular to a numerically controlled spherical surface grinder. Background technique [0002] In the valve industry, the roundness and precision of the ball valve ball are the key to the product. At present, most ball valve manufacturers use the grinding method for the processing of the ball, that is, the surface of the ball is floated and ground with oilstone after finishing the car. The main problems of this process method are that the grinding allowance is small, the requirements for the previous process are high, the precision is poor, and the efficiency is low. Therefore, CNC spherical grinding machine has become the inevitable development of sphere processing equipment. The processing principles of CNC spherical grinding machine for spheres mainly include forming grinding wheel grinding method and non-forming grinding wheel grinding method. The structure mainly includes base, slide p...
