Problems solved by technology

However, the deburring of the small holes intersecting the inner wall of the deep hole has not been well solved. Because the deep hole is too deep, the special push-and-turn tool cannot be inserted, and the pneumatic rotary tool cannot be controlled when it is extended into such a deep hole. And it is easy to scratch the inner wall of the workpiece and cause scrapping. The anti-scraper deburring can not control the strength, the deburring is very uneven, the effect is very poor, and it is easy to scratch the hole wall, and the file is even more difficult to use.

Embodiment Construction

[0013] Describe the present invention in detail below in conjunction with accompanying drawing:

[0014] like figure 1 and figure 2 As shown, a tool for deburring the inner wall of a deep hole intersecting small holes, including a deburring knife 1 and a handle 6 . like figure 2 As shown, the deburring knife 1 includes a knife shaft and a blade portion, the blade portion is in the shape of a fork, and the fork portion has two fork branches 9 and 10 . The forks 9 and 10 are elastic forks, that is, the distance between the two forks can be slightly changed with the action of external force. And the outer side of the fork branch 9 is provided with a cutting edge 8 . like figure 1 As shown, handle 6 can directly adopt screwdriver handle. But described screwdriver shank needs the screwdriver head to be cut off. One end of the burr knife bar is connected with the end of the handle through the connecting sleeve 5, and is fixed with a stop screw 7. like figure 1 As shown, a...

Abstract

The invention discloses a tool for deburring an orifice of a small hole communicated with an inner wall of a deep hole. The tool comprises a burred knife and a handle, the edge part of the burred knife is shaped like an elastic fork with two fork branches, and the outer side of one fork branch is provided with an edge; a rod of the burred knife is provided with a guide sleeve, a compression spring and a stopping block, wherein the guide sleeve is arranged near the edge part, the inner hole of the guide sleeve is matched with the periphery of the rod of the burred rod, and the compression spring is arranged between the guide sleeve and the stopping block; and the stopping block can move along the axial direction of the rod of the knife and is provided with a stopping screw. The tool has the advantages of low cost and simple structure.

Description

technical field [0001] The invention relates to a cutter device, and relates to an improved cutter device for deburring the inner wall of a deep hole intersecting with the opening of a small hole. Background technique [0002] There are many ways to deburr the inner hole, including file deburring, reverse scraper deburring, special push-and-turn tool deburring, special pneumatic rotary tool deburring, and special equipment deburring. However, the deburring of the small holes intersecting the inner wall of the deep hole has not been well solved. Because the deep hole is too deep, the special push-and-turn tool cannot be inserted, and the pneumatic rotary tool cannot be controlled when it is extended into such a deep hole. And it is easy to bruise the inner wall of the workpiece and produce scrap, and the anti-scraper deburring can not control the strength, the deburring is very uneven, the effect is very poor, and it is easy to bruise the hole wall, and the file cannot be use...
