Embodiment Construction

[0014] refer to Figure 1~2 , the present invention is composed of electromechanical two parts, the mechanical part includes a bracket 4, a rotating arm 5 and an adjustable ejector rod 6; the control device includes a DC power supply ①, a multivibrator ②, a sensor ③, a differential rectifier circuit ④, a digital panel meter ⑤ and power interface ⑥. The bracket 4 is fixed on the grinding wheel frame 3, the rotating arm 5 is connected with the bracket 4 through a hinge, and the adjustable ejector rod 6 is a micrometer with a scale value of 0.01mm, which is fixed on the rotating arm 5 and is used to change the machining diameter. Adjustment, the bracket 4, the rotating arm 5, the adjustable ejector rod 6 and the probe of the sensor ③ are centered, and after adjustment, they are fixed and moved together with the grinding wheel frame 3 being fed. The sensor ③ is fixed on the bed, constant, its primary coil is electrically connected to the multivibrator ②, and the secondary coil is...

Abstract

The automatic locating and grinding method in general cylindrical grinding machine includes the following steps: fixing the mandrel through rotating arm and rack onto the wheel slide for shifting, fixing the sensor to machine bed and connecting electrically to the differential rectifier circuit, connecting the power interface electrically to the electric executor of the grinding machine and the digital panel meter through a switch; cutting off the switch via setting the potentiometer to 0 position, trial grinding one axial diameter to determine the basic paired grinding radius and the escape point; and regulating the potentiometer to increase or decrease the machined radius. The said method can grind ideal paired ground parts.

Description

technical field [0001] The invention relates to a grinding matching method, in particular to an automatic positioning grinding matching method for a universal cylindrical grinder. Background technique [0002] Rotating shafts and bearings, valves and valve bodies, rolling guide columns of molds, etc. are all mating parts, and their clearance or interference is obtained by matching grinding of the base hole matching shaft. [0003] In the known trial cutting and grinding method, the actual size of each aperture is measured before the grinding, and the same size is grouped, numbered, tabulated, and the mating shaft diameter is ground to the ideal size by repeated trial cutting according to the requirements of the matching properties. , The disadvantage of this method is that the processing and measurement are extremely cumbersome, the positioning is not accurate, and waste products are easy to produce. [0004] The document "Instructions for "PMKZ-2 Active Measurement and Con...
