Problems solved by technology

The disadvantage of this method is that it is impossible to determine the pressing angle of the positioning pin, and it is easy to skew the pin during the pressing process, and even the components are scrapped.
Since the inclined hole of the bushing of the shell assembly is shallow, if the pin is not positioned accurately, it is easy to tilt the pin or the positioning pin is not pressed deep enough, which may lead to the scrapping of components when reworked

Embodiment Construction

[0028] see Figure 4 as well as Figure 5 , the present invention provides a kind of oblique hole depressing tool, which includes a positioning block 1 and a movable depressing mandrel 4; the movable depressing mandrel 4 is inserted on the positioning block 1 and can be opposite to the positioning block Movement; the end of the movable press pin mandrel 4 is provided with a pin hole 5 along the axial direction of the movable press pin mandrel 4 . The present invention is improved on the basis of the existing mandrel, and a positioning block 1 is added. When in use, the positioning block 1 is fixed on the end face of the bushing hole of the shell assembly, and the angle relationship is set by an angle ruler according to the requirements of the drawings. At the same time, use the adjusted angle ruler to adjust the angular relationship between the movable depressing mandrel 4 and the positioning block 1. After determining the angular relationship, you can directly knock the mova...

Abstract

The invention belongs to the field of machining or mechanical maintenance, and relates to an oblique hole pin pressing tool and method. The oblique hole pin pressing tool comprises a positioning blockand a movable pin pressing core rod. The movable pin pressing core rod is inserted on the positioning block and can move relative to the positioning block; a pin hole is formed in the end of the movable pin pressing core rod in the axial direction of the movable pin pressing core rod. According to the oblique hole pin pressing tool and method, the structure is simple, pressing can be performed accurately, and working efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing or mechanical maintenance, and relates to an oblique hole pin pressing tool and a pin pressing method, in particular to a housing assembly bushing oblique hole pin pressing tool and a pin pressing method. Background technique [0002] An aero-engine casing assembly (see figure 1 ) with inclined holes in the bushing (see figure 2 ), the positioning pin needs to be pressed into the inclined hole. At present, when the positioning pin is pressed in, the mandrel is mainly used (see image 3 ) After fixing the pin, press it directly into the inclined hole of the shell bushing. The specific process is: adopt general depressing tooling ( image 3 shown) yes figure 1 Press-fit the positioning pin in the bushing hole of the housing assembly in image 3 On the tooling shown in the figure, after confirming the pressing position with the naked eye, tap it with a hammer along the direction of the inc...
