Embodiment Construction

[0011] In this technical solution, during the debugging process of the machine tool, the adjustment of the left and right angles does not need to dismantle the grinding wheel, the dressing arm, etc., and does not need to install special tooling. It only needs to be read by the dial indicator when moving the grinding head base. The specific value can realize accurate measurement, and when the accuracy of the left and right spindle ends of the machine tool is parallel or perpendicular to the dresser, the accuracy can be quickly restored by using this device, see figure 1 As shown, the left and right grinding heads are respectively fixed on the grinding head base, and the base is assembled with the bed 5. The left and right grinding heads are respectively equipped with the grinding wheel main shaft 2, and the main shaft 2 is equipped with the grinding wheel 1. The left and right grinding Both sides of the head are respectively equipped with zero device 4, see figure 2 As shown, ...

Abstract

The invention discloses a null-setting device of a double-ended grinding machine. The double-ended grinding machine comprises left and right grinding heads and a machine body; the null-setting devices are mounted at the two sides of the left and right grinding heads, respectively; each null-setting device is assembled on a grinding head base by use of a measuring rod; measuring blocks are assembled and fixed with the machine body; adjusting nuts are screwed down on the measuring blocks, respectively; locking blocks are inserted in the inner holes of the adjusting nuts and fastened by using locking screws; a dial indicator inserted in the locking block by an insertion depth so that a contact on the dial indicator is capable of touching the surface of the measuring rod. At least two adjusting nuts are provided, and the locking blocks as many as the adjusting nuts and correspondingly inserted and mounted. The null-setting devices are utilized upon loss of parallel precision of the end faces of left and right main shafts of the machine, vertical precision to a dresser, and the like, so that the precision can be recovered quickly; the null-setting device is convenient, fast, accurate, and the like.

Description

technical field [0001] The invention relates to a zero position device, which is especially suitable for use on double-end grinding machines. Background technique [0002] The double-end grinding machine is suitable for high-precision and large-scale processing of rollers, ferrules, auto parts, hydraulic valves, etc. In order to obtain high grinding accuracy during the processing of the double-end grinding machine, the workpiece must be ground The area can rotate on its own. [0003] To achieve the above requirements, the solution must be to adjust a small angle of the left and right grinding heads in the horizontal plane and the vertical plane. The existing method for adjusting the angle of the grinding head (horizontal angle, vertical angle): remove the grinding wheel together with the grinding wheel flange, install a dial indicator on the right grinding wheel spindle, make the contact touch the end surface of the left spindle, and turn the spindle. The difference betwee...
