Embodiment Construction

[0014] Below the utility model will be further described in conjunction with the embodiment in the accompanying drawing:

[0015] Such as 1~ image 3 Shown: Including the inner ring of the position marker 1, the limit mandrel 2, the clamp seat 3, the first integral nut 4, the fixing plate 5, the adjusting plate 6, the first hexagon socket screw 7, the counterweight 8, and the second integral Nut 9, second hexagon socket head cap screw 10, cylindrical pin 11.

[0016] The outer circle of the limiting mandrel 2 is installed in the positioning hole of the vehicle fixture seat 3 . The fixed plate 5 and the vehicle fixture seat 3 are fixedly connected together by two pins 11 and two hexagon socket head cap screws 10. The hypotenuse of the fixed plate 5 is in contact with the inclined surface of the adjustment plate 6. The adjustment plate 6 can be moved forward and backward to adjust the limit mandrel. angular position. Counterweight 8 is installed on the vehicle fixture seat 3 ...

Abstract

The invention relates to a processing technology of inner threaded holes of a position marker. The processing technology adopts the following processing steps: mounting a jig through a numerical control lathe flange plate, adjusting a central position and fastening through a screw; arranging the inner ring of the position marker onto the positioning outer circle of a limiting mandrel, and fixing through a second integral nut; pushing into a regulating plate and fixing the angle phase position of the limiting mandrel; programming a numerical control machine tool program and arranging according to the program: turning a small plane, drilling a bottom hole, drilling and boring a threaded bottom hole and turning a thread through a screwer; loosening a first inner hexagon screw and loosening a first integral nut after completing the processing of the first threaded hole; and performing operation on the premise of not allowing to loosen the second integral nut, withdrawing the regulating plate, rotating the limiting mandrel for 90 degrees, further pushing into the regulating plate, completing the 90-degree equal division and processing the other three threaded holes according to the steps. The processing technology disclosed by the invention can be used for applying the functions of a precision numerical control lathe, realizing hole drilling, hole boring and thread turning and forming, ensuring the requirements of form and position tolerance and ensuring the requirements of various technical indexes, is simple and convenient in operation and stable in quality and can be used for greatly improving the product qualification rate.

Description

technical field [0001] The invention relates to a processing technology for threaded holes of the inner ring of a position marker, in particular to a precision internal thread turning processing method with extremely high requirements on shape and position tolerance, and belongs to the technical field of mechanical processing technology. Background technique [0002] In the machinery manufacturing industry, the assembly of parts in the mechanical structure requires threads to fix, and the machining accuracy of the threaded holes has a direct impact on the assembly accuracy of the parts. In the prior art, the machining of threaded holes is usually done by machine tool firstly, and then the threads are machined by manual operation with a tap. This machining method has low precision and cannot meet the shape and position tolerance requirements of the design documents. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantage...
