Description
Technical Field
The utility model relates to a honing tool. In particular to a tool for honing a shaft hole on an intermediate body of an automobile supercharger.
Background
It is known in the supercharger industry that automatic honing machines are currently used for honing shaft holes in the supercharger intermediate. The automatic honing machine is mainly composed of a motor, a chuck and a honing rod. The automatic honing machine can be used for honing and processing the shaft hole on the intermediate of the supercharger, but the equipment investment is more and the production cost is higher because clamps such as chucks are required to be equipped. And because the automatic honing machine is only composed of a motor, a chuck and a honing rod, no depth fixing measure is adopted, the machining depth precision is completely determined by manual measurement, and the quality is difficult to ensure.
Disclosure of utility model
The utility model aims to solve the problems and provide the depth-fixing honing device for machining the shaft hole of the intermediate body of the supercharger. By adopting the depth-setting honing device, not only the investment and the production cost can be reduced, but also the processing quality can be ensured.
The above problems to be solved by the present utility model are achieved by the following technical solutions:
The utility model relates to a depth-setting honing device for machining a supercharger intermediate shaft hole, which comprises an intermediate. The axial center and the side wall of the intermediate body are respectively provided with a shaft hole and an oil return hole. The honing rod is arranged in the shaft hole and is in rotatable fit with the shaft hole, and the inner end of the oil return hole extends downwards and inwards to the periphery of the shaft hole. The method is characterized in that: the upper end of the intermediate body is provided with a distance sleeve, and the distance sleeve and the intermediate body are rotatably matched together. The inner diameter of the distance sleeve is matched with the shaft hole. The lower end of the honing rod penetrates through the distance sleeve and then stretches into the shaft hole in the intermediate body. Screw holes are formed in the side walls of the distance sleeves, and fastening screws are arranged in the screw holes. The inner side wall of the lower end of the shaft hole is provided with a radial bulge, and a gap is reserved between the radial bulge and the lower end of the honing rod.
According to a further improvement scheme of the utility model, the radial protrusions are located between the upper side and the lower side of the inner end of the oil return hole.
In a further development of the utility model, a planar bearing is arranged between the distance sleeve and the intermediate body, by means of which the distance sleeve and the intermediate body are rotatably coupled together.
According to the scheme, the upper end of the intermediate body is provided with the distance sleeve, and the distance sleeve and the intermediate body are rotatably matched. And a radial bulge is processed on the inner side wall of the lower end of the shaft hole, and a gap is reserved between the radial bulge and the lower end of the honing rod. The honing depth of the intermediate shaft hole can be determined by the distance sleeve and the radial protrusions. When the honing tool works, the intermediate shaft hole can be subjected to depth-fixing honing by manually holding the intermediate body only by connecting the honing rod with the output shaft of the motor. Compared with the prior art, the device does not need a special chuck, can reduce equipment investment and production cost. And because the upper end of the intermediate body is provided with the distance sleeve, the inner side wall of the lower end of the shaft hole is provided with the radial bulge, and the honing depth of the shaft hole of the intermediate body can be determined through the distance sleeve and the radial bulge. Compared with the background technology, the honing depth can be automatically determined by depth setting measures, and the processing quality is ensured.

Detailed Description
As shown in fig. 1, the depth-determining honing device for machining a supercharger intermediate shaft hole according to the present utility model includes an intermediate 7. The axial center and the side wall of the intermediate body 7 are respectively provided with a shaft hole and an oil return hole 1. The honing rod 2 is arranged in the shaft hole and is matched with the shaft hole in a rotatable mode. The inner end of the oil return hole 1 extends downwards and then inwards to the periphery of the shaft hole. The upper end of the intermediate body 7 is provided with a distance sleeve 4 which is rotatably matched with the intermediate body. The inner diameter of the distance sleeve 4 is matched with the shaft hole. The lower end of the honing rod 2 passes through the distance sleeve 4 and then extends into the shaft hole on the intermediate body 7. Screw holes are formed in the side walls of the distance sleeves 4, fastening screws 5 are arranged in the screw holes, and locking and fixing between the distance sleeves 4 and the honing rod 2 can be achieved by screwing the fastening screws 5. The inner side wall of the lower end of the shaft hole is provided with a radial bulge 8, and the radial bulge 8 is positioned between the upper part and the lower part of the inner end of the oil return hole 1 and is provided with a gap 9 with the lower end of the honing rod 2.
In order to realize rotatable matching between the lower end of the distance sleeve 4 and the upper end of the intermediate body 7, a plane bearing 6 is arranged between the distance sleeve 4 and the intermediate body 7, and the distance sleeve 4 and the intermediate body 7 are rotatably matched together by the plane bearing 6.
When the honing tool works, the outer end of the honing rod 2 is connected with an output shaft of a motor, and the intermediate body 7 is held manually. The motor is started, and the motor drives the honing rod 2 to rotate, so that the depth-fixing honing of the shaft hole on the intermediate body 7 is realized.
