Abstract

The invention discloses a double-end-face grinding machine for automobile oil pump valve spools. The double-end-face grinding machine comprises a machine body, a clamp, a first grinding device and a second grinding device. The clamp can rotate around the self axis and comprises a body extending radially, the body is in the shape of an equilateral polygon in the radial cross section thereof and capable of rotating around a central axis of the equilateral polygon, a plurality of grooves are formed in the outer wall surface of the body, a pressing plate corresponding to each groove is arranged on the same, the first side of each pressing plate is hinged to the body, the second side of each pressing plate is connected with the first end of an elastic element, a plurality of sliding grooves corresponding to the pressing plates are formed in the body, and the second end of each elastic element is slidably arranged in the corresponding sliding groove. The first grinding device comprises a first motor and a first grinding wheel driven by the first motor, the second grinding device comprises a second motor and a second grinding wheel driven by the second motor, and the first grinding wheel and the second grinding wheel are bilaterally symmetrical along a center line of the clamp.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a double-end surface grinding machine for an automobile oil pump spool. Background technique [0002] The car oil pump supplies the oil in the fuel tank to the engine. The automotive oil pump spool is a valve part of the automotive oil pump that uses its movement to achieve the basic function of flow control. [0003] Such as figure 1 As shown, the automobile oil pump valve core 1 has a central core shaft 11 and a protrusion 12 arranged on the central core shaft. In order to ensure the normal operation of the automobile oil pump, the two sides of the projection 12 must be symmetrical with respect to the axis of the central mandrel. [0004] In the traditional process, one side of the bump 12 is usually processed first, and after the side is processed, it is turned over once, and then the other side is processed. However, with this processing method, the processing accuracy and quality ca...
