Problems solved by technology

This kind of fixed mandrel is very inconvenient when loading and unloading workpieces. It is inefficient to loosen the bolts with a wrench and then replace the workpieces.
The eyepiece seat is a part with a very long taper. If the mandrel-type fixture is used, the rigidity of the processing is not good and the length of the positioning step is not enough, which will cause vibration during processing, so that the surface finish and processing accuracy cannot be achieved. drawing requirements, thus greatly reducing the processing quality, reducing the qualified rate and increasing the cost

Embodiment Construction

[0013] like image 3 As shown, this is a self-locking cone, (from left to right) the external thread 1 at the front end is on the protruding cylinder, followed by the internal cone 2, then the external thread 3, and finally the flattened part 4.

[0014] like Figure 4 As shown, this is a cone seat structure, (from left to right) the front end is a cylinder 5, followed by an outer cone 6, which has a sunken circular hole, and the internal thread 7 is arranged on the circular hole, and the external A cylindrical step 8 is set at the left end of the cone 6 .

[0015] like figure 2 As shown, this is the structure of the workpiece to be processed, (from left to right) an inner step 11 is set at the wide part of the cone part 9, and the rear part is a cylindrical internal thread 10.

[0016] like figure 1 As shown, the fixture is composed of a cone seat and a self-locking cone. The external thread 1 protruding from the front end of the cylinder on the self-locking cone is inse...

Abstract

The invention relates to a jig for finishing machining of eyepiece seat parts in a laser range finder for tanks. The structure of the present invention is composed of a self-locking cone and a cone seat, the external thread of the front end of the self-locking cone matches the internal thread of the cone seat, the inner cone of the self-locking cone matches the outer cone of the cone seat, and the self-locking There is an external thread behind the inner cone of the cone, and the rear end of the self-locking cone is a flattened place. The invention solves the problems of vibration during processing in the past, and the surface smoothness and processing precision cannot meet the requirements of the drawings, so that the processing quality is greatly reduced, the qualified rate is reduced, and the cost is increased. The invention can be self-locking, that is, when the workpiece is screwed to the fixture in one step, it will play an axial fixing role without further tightening. The processed eyepiece seat has precise positioning, high behavioral precision, and high processing precision, and can realize concentricity. The degree and perpendicularity are 0.01mm, and it can be installed on the CNC car or ordinary car, which not only ensures the accuracy but also improves the efficiency and simplifies the structure.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a finishing machining fixture for an eyepiece seat part in a laser range finder for a tank, which is a tooling fixture used on a numerically controlled lathe. Background technique [0002] Before the present invention, when processing the eyepiece seat in the laser rangefinder, the mandrel type fixture used was an integral cylindrical band with an external thread to axially fix the mandrel. It is extremely inconvenient to load and unload workpieces when using this fixed mandrel. It is necessary to loosen the bolts with a wrench and then change the workpieces, which is inefficient. The eyepiece seat is a part with a very long taper. If the mandrel-type fixture is used, the rigidity of the processing is not good and the length of the positioning step is not enough, which will cause vibration during processing, so that the surface finish and processing accuracy cannot be achieved. Drawing requi...
