Detailed Description
The utility model is described in further detail below with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 4, a tooling fixture for turning and grinding an outer circle of a valve disc comprises an upper tooling 1, a lower tooling 2 and two bar stringing rods 3 for connecting the upper tooling and the lower tooling.
The upper tool 1 comprises a disc seat 10 and a protruding column 11 protruding from the disc seat 10, one end of the protruding column 11 is a first inclined surface 101, two first through holes 201 are arranged on the upper tool 1 at intervals, and the first through holes 201 penetrate through the disc seat 10 to the first inclined surface 101 at one end of the protruding column 11.
The position of the lower tool 2 is opposite to that of the upper tool 1, the end face of one end, opposite to the upper tool 1, of the lower tool 2 is provided with a second inclined face 102 with the same angle as that of the first inclined face 101 on the protruding column 11, and two second through holes 202 aligned with the first through holes 201 penetrate through the lower tool 2.
The two strings of rods 3 pass through the aligned first through hole 201 and second through hole 202, so as to connect the upper tool 1 and the lower tool 2, and the two strings of rods 3 are used for connecting the stacked valve discs 100 in series.
In the structure, when the valve disc assembling tool is used, the two inclined holes of the valve disc 100 are connected to the string rod 3 in series, the bottom plane of the valve disc 3 is attached to the inclined plane of the lower tool 2, the two first through holes 201 of the upper tool are connected to the string rod in series, and the string rod is placed on a machine tool to be tightly pushed for machining.
