Problems solved by technology
[0002] In mechanical manufacturing, in order to achieve a certain accuracy and installation requirements, two holes on different parts need to have the same axis accuracy, that is, the requirements of coaxiality. The common process methods to achieve the above requirements are: one is matching The method is to superimpose two parts together and then drill or ream at the same time. However, some parts cannot achieve superimposed drilling or reaming due to structural or other reasons. Therefore, the process method for such cases Generally, the method of scribing is used, or the method of coordinate machine tools is used to realize drilling.
There are certain defects in these methods; first of all, for some special parts, it cannot be realized for the method of superimposing parts as holes, and the use conditions are limited; although the method of scribing is simple and easy, but, It has the defects of poor quality accuracy, high labor intensity, and low labor efficiency; and the method of using coordinate machine tools to achieve drilling coaxiality requires high efficiency and high precision, but because coordinate machine tools are generally It has a high price, so there is a high investment in equipment, which is not suitable for small and medium-sized enterprises and the needs of the maintenance industry

The invention discloses a hole position alignment device. In the device, a short spring is arranged on the upper part of a positioning cone; the positioning cone is arranged in the middle of a small hole in the middle of a body through an outer circle at the upper end of the positioning cone; a long spring is arranged in a middle blind hole of the positioning cone; a gland is arranged on the upper opening part of the blind hole of the positioning cone in a threaded fit mode; a small hole is formed in the middle of the gland; and a central punch passes through the small hole in the middle of the gland and the small hole on the bottom surface of the cone. The device has the characteristics of simple structure, convenience of use and high precision, can effectively improve labor productivity, and particularly meets the requirements of small and medium enterprises and maintenance industries at the same time.
Description
technical field [0001] The invention relates to a hole alignment device, in particular to a hole alignment device, which belongs to the technical field of fitter tools. Background technique [0002] In mechanical manufacturing, in order to achieve a certain accuracy and installation requirements, two holes on different parts need to have the same axis accuracy, that is, the requirements of coaxiality. The common process methods to achieve the above requirements are: one is matching The method is to superimpose two parts together and then drill or ream at the same time. However, some parts cannot achieve superimposed drilling or reaming due to structural or other reasons. Therefore, the process method for such cases Generally, the method of scribing is used, or the method of coordinate machine tools is used to realize drilling.
