Abstract
A tap slip-resistant sheath, comprising: the screw tap antiskid cover main part, screw tap antiskid cover main part inboard are seted up and are used for the terminal hole of clamp screw tap, and the screw tap antiskid cover main part outside is the profile of buckle pistol drill chuck, and is equipped with the opening that is used for tightening up the hole on the inner hole wall one, and the hole shape cooperates with the terminal outer wall profile of screw tap. Has the advantages that: when avoiding the tapping of pistol drill, arouse the screw tap to skid inadequately because of the drill chuck clamp force, can improve the clamp force through reducing the opening, reach the effect that the screw tap is difficult for skidding.
Description
Technical Field
The invention relates to a screw tap antiskid sleeve for preventing a screw tap from slipping caused by insufficient clamping force of a drill chuck during tapping of a gun drill.
Background
The existing screw tap clamp comprises a T-shaped connecting piece, an adjusting nut, an adjusting handle and a clamping jaw, wherein the vertical end of the T-shaped connecting piece is connected with the upper end of the adjusting nut through threads, the lower end of the adjusting nut is connected with the upper end of the adjusting handle through threads, two horizontal ends of the T-shaped connecting piece are respectively rotatably connected with the middle of the clamping jaw, the inner side of the lower end of the clamping jaw is abutted to the outer surface of the adjusting nut, and the upper end of the clamping jaw is used for clamping a screw. The disadvantages are that: the structure is complicated, the cost is high, and the clamping effect is general.
When using the pistol to bore the tapping now, use the drill chuck to press from both sides tight screw tap rear end middle part round handle department and carry out the tapping usually, cause the screw tap to skid because the frictional force between drill chuck and the screw tap is not enough easily to damage drill chuck and screw tap, reduce work efficiency, improve manufacturing cost.
Disclosure of Invention
The invention aims to solve the defects in the prior art, and provides a screw tap antiskid sleeve for preventing a screw tap from slipping caused by insufficient clamping force of a drill chuck when a pistol drill performs tapping.
In order to achieve the purpose, the invention adopts the following technical scheme: a tap slip-resistant sheath, comprising: the screw tap antiskid cover comprises a screw tap antiskid cover main body, wherein an inner hole used for clamping the tail end of a screw tap is formed in the inner side of the screw tap antiskid cover main body, the outer side of the screw tap antiskid cover main body is the outline of a clamping pistol drill chuck, and an opening used for tightening the inner hole is formed in the wall of the inner hole.
Furthermore, inner holes penetrating through the front end and the rear end of the screw tap antiskid sleeve main body are formed in the inner side of the screw tap antiskid sleeve main body, and openings penetrating through the inner hole walls from front to back are formed in the inner hole walls.
Furthermore, the inner hole is a square inner hole.
Furthermore, the profile of the screw tap antiskid sleeve main body outside buckle pistol drill chuck is circular.
Furthermore, the outline of the screw tap antiskid sleeve main body outside buckle pistol drill chuck is polygonal.
Furthermore, the contour of the screw tap antiskid sleeve main body outside buckle pistol drill chuck is triangle.
Furthermore, the outline of the screw tap antiskid sleeve main body outside buckle pistol drill chuck is heart-shaped.
Furthermore, the inner hole walls of the symmetrical openings are provided with grooves from front to back.
Furthermore, the included angle of the square inner hole is a fillet.
Furthermore, the included angle of the profile of the triangular screw tap antiskid sleeve main body is a round angle.
The invention has the beneficial effects that: when avoiding the tapping of pistol drill, arouse the screw tap to skid inadequately because of the drill chuck clamp force, can improve the clamp force through reducing the opening, reach the effect that the screw tap is difficult for skidding.
