Abstract
The utility model relates to a double-ear-hole special cutter which is characterized in that two screw holes at the front end of a lengthened cutter body are respectively provided with a first transition sleeve and a second transition sleeve; a thin boring hole alloy block is welded into the first transition sleeve and is fixed by a first fastening screw; and a thick boring hole alloy block is connected in the second transition sleeve and is fixed by a second fastening screw. The double-ear-hole special cutter has the beneficial effects that: the processing is convenient, the efficiency is high, and the technical requirement of high accuracy of a constant-speed central fork of a four-wheel driving automobile can be met.
Description
Technical field
The utility model relates to fork machine components Vehicle Processing cutter field, 4 wheel driven electrical automobile constant speed center, specifically is meant ears hole dedicated tool.
Background technology
4 wheel driven electrical automobile constant speed center fork is a kind of auto parts and components new product at present, the manufacturing process of this new product does not have well-known processes, need inquire into the new processing technology of utility model according to the structure of automobile constant velocity center fork, to guarantee the accuracy and the reliability of 4 wheel driven electrical automobile constant speed center fork part processing, but be subjected to the influence of its existing manufacturing process, that the earhole of fork both sides, 4 wheel driven electrical automobile constant speed center can't be processed is very accurate.
Summary of the invention
In view of the defective that prior art exists, the purpose of this utility model provide a kind of easy to process, efficient is high, satisfy the ears hole dedicated tool that 4 wheel driven electrical automobile constant speed center fork high precision technology requires.
For achieving the above object, the technical solution that the utility model adopted mainly comprises: lengthening cutter hub, first spacer shell, second spacer shell, thin bore hole alloy block, rough bore alloy block, first holding screw, second holding screw; It is characterized in that: on two silk holes of lengthening cutter hub front end, first spacer shell and second spacer shell are housed respectively, thin bore hole alloy block is welded in first spacer shell, and fix by first holding screw, the rough bore alloy block is connected in second spacer shell, and is fixed by second holding screw.
The beneficial effect of described ears hole dedicated tool is: easy to process, efficient is high, satisfy the requirement of 4 wheel driven electrical automobile constant speed center fork high precision technology.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a side view of the present utility model.
The specific embodiment
Fig. 1, Fig. 2 Reference numeral are as follows: lengthening cutter hub 1, first spacer shell 2, second spacer shell 3, thin bore hole alloy block 4, rough bore alloy block 5, first holding screw 6, second holding screw 7.
In the structure chart of Fig. 1, ears hole dedicated tool shown in Figure 2, its primary structure comprises: on two silk holes of lengthening cutter hub 1 front end first spacer shell 2 and second spacer shell 3 are housed respectively, thin bore hole alloy block 4 is welded in first spacer shell 2, and it is fixing by first holding screw 6, rough bore alloy block 5 is connected in second spacer shell 3, and fixing by second holding screw 7.
Operation principle of the present utility model: rough bore alloy block 5 is responsible for the heavy boring earhole, and thin bore hole alloy block 4 is responsible for thin boring earhole, and on a cutter hub, two bore hole alloy blocks are worked simultaneously, becomes main sword and pays sword; With cutter body lengthening, can the preceding hole of boring, boring metapore continuously again.Thereby guarantee the axiality in ears hole; Described holding screw one is to play the role of fastening, the 2nd, play adjustment cutter tile height.Through fork ears hole, the 4 wheel driven electrical automobile 4 wheel driven electrical automobile constant speed center of this special tool processing, surface roughness can reach the Ra1.6mu of grinding.
