Description

Nest cutting positioning tool for lateral through hole of cylinder

Technical Field

The utility model relates to a technical field of mould specifically is a nest location frock of drawing of cylinder side direction through-hole.

Background

In order to prevent connection loosening caused by repeated vibration during use of mechanical joints such as bolt connection and the like, and finally to prevent connection elements from falling off and losing efficacy, safety needs to be driven into a plurality of joints after fastening connection is completed. The fuse is generally formed by matching a bendable fuse and a chuck with one end of the fuse playing a role of clamping stagnation and preventing falling through a round hole on the side of the chuck, and the bendable fuse and the chuck are connected through welding to form a permanent connection, so that in order to realize the welded connection of the fuse and the chuck, a surface boundary of the round hole of the chuck needs to be subjected to dimpling and chamfering. However, since the safety chuck is cylindrical, the chuck rolls when the circular hole is hollowed, which affects the precision of making chamfers of the hollowed hole, and therefore, how to conveniently and quickly position the cylindrical chuck is the key to improve the manufacturing precision and efficiency of the chuck.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, namely the problems in the prior art, the utility model provides a pit-cutting positioning tool for a cylindrical lateral through hole, which comprises a positioning tool U-shaped base, wherein a U-shaped groove for placing a chuck is arranged above the positioning tool U-shaped base, the U-shaped groove is a through groove, and the depth of the U-shaped groove is half to one time of the diameter of the chuck;

the internally mounted in U type groove has the locating pin, the locating pin sets up the inside central point in U type groove and puts, and the diameter ratio dop diameter of locating pin is less than 0.1mm, the top processing of locating pin has 0.5mm chamfer.

The utility model discloses a further set up to: the U-shaped base of the positioning tool is of a cuboid structure.

The utility model discloses a further set up to: the width of the U-shaped groove is 0.1mm larger than the diameter of the clamping head.

The utility model has the advantages that: according to the cavity scribing positioning tool for the lateral through hole of the cylinder, the U-shaped groove is combined with the positioning pin inside to position the cylinder with the lateral through hole, five degrees of freedom of the cylinder chuck are limited, the last degree of freedom is limited by downward force of a cavity scribing drill during chamfer manufacturing, and therefore six degrees of freedom are limited during cavity scribing and chamfer manufacturing, and positioning is accurate; in addition, clearance fit is formed among the U-shaped groove, the positioning pin and the cylindrical chuck, so that the chuck can be conveniently detached.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The utility model provides a nest scribing location frock of cylinder side direction through-hole, the dop diameter that the U type groove 2 degree of depth of location frock U type base 1 is 1/2 ~ 1 times, avoid probably taking place to rotate when digging the nest to and produce interference with the nest scribing drill, if the dop diameter that U type groove 2 degree of depth is less than 1/2, the dop probably takes place to rotate when digging the nest, if be greater than the dop diameter, because U type groove 2 is too deep, produce interference with the nest scribing drill;

the width of a U-shaped groove 2 of the U-shaped base 1 of the positioning tool is 0.1mm larger than the diameter of a clamping head, and when the clamping head is arranged in the U-shaped groove 2, the clamping head is in clearance fit with the U-shaped groove 2, so that the clamping head can be conveniently detached and placed;

the U-shaped groove 2 is a through groove, so that the clamping head can be conveniently detached and placed;

the positioning pin 3 in the U-shaped groove 2 is arranged at the central position of the bottom of the U-shaped groove 2, the hole scratching positioning tool for the lateral through hole of the cylinder mainly comprises a U-shaped base 1 and the positioning pin 3 additionally arranged in the U-shaped groove 2, one side of a circular through hole of a cylindrical chuck is matched and positioned with the positioning pin 3 and then arranged below a hole scratching drill during hole scratching positioning, the manufacturing of a chamfer is completed on the other side of the circular through hole, the diameter of the positioning pin 3 is 0.1mm smaller than that of the chuck through hole, the chuck is in clearance fit with the positioning pin 3 during matching, the chuck is convenient to detach and place, and finally a chamfer with the radius of 0.5mm is manufactured at the top of the positioning pin 3;

the U-shaped base 1 of the positioning tool is rectangular, and is convenient to fix and operate on a drilling machine manually.

While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention, and particularly, all technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict.
