Embodiment Construction

[0014] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0015] The invention discloses a fixture 2 for processing a valve core of an automobile oil pump, which comprises a body 21 , a pressing plate 22 and an elastic element 23 .

[0016] figure 2 is the side view of fixture 2. The main body 21 is a regular polygon in a transverse section. exist figure 2 In , the horizontal direction refers to the direction parallel to the paper surface. The body 21 can rotate around its own axis. The own axis of the body 21 is also the central line of the regular polygon, which is parallel to the horizontal axis. The outer wall surface of the body 21 is the surface formed by extending the sides of the regular ...

Abstract

The invention discloses a clamp for machining an automobile oil pump valve element. The clamp comprises a body, the body is in a regular polygon shape in the radial section, and the body can rotate around the central axis of the polygon shape. A plurality of grooves are formed in the outer wall face of the body, each groove is provided with a pressing plate corresponding to the groove, 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, and a plurality of sliding grooves corresponding to the pressing plates are formed in the body. The second end of each elastic element is arranged in the corresponding sliding groove in a sliding mode. Each sliding groove is provided with a first end and a second end, each pressing plate has two working positions, the second end of each elastic element is located at the first end of the corresponding sliding groove, and a closed space is formed by each pressing plate relative to the corresponding groove, wherein an automobile oil pump valve element is located in the closed space. When the body rotates, the second end of each elastic element slides to the second end of the corresponding sliding groove from the first end of the corresponding sliding groove, and the pressing plates are opened relative to the grooves.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for processing the spool of an automobile oil pump. Background technique [0002] The car oil pump supplies the oil in the fuel tank to the engine. Automobile oil pump spool 1 is a valve part of the automobile oil pump to realize the basic function of flow control by means of its movement. [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 cannot be guaranteed...
