Description
Technical field
The invention belongs to equipment Technology fields, are related to a kind of template drill bushing punching pin.
Background technique
Template drill bushing plays a part of to position and be oriented in drilling part to drill bit, since drill bit can generate friction to drill bushing
And impact, it is desirable to which drill bushing and template cooperation are close, cover to prevent rotation stop and loosen and fall off.Template is when diamond setting covers, with core
The punching pin of axis gets recess on the template of drill bushing surrounding, and certain clamping action is played to drill bushing, and traditional punching pin is integrated
Structure, with punching pin when dent sunken on template, the punch branch of punching pin generates abrasion, or even can produce fracture, when formed punch goes out
When existing problem, it can not be repaired and be replaced, entire punching pin is resulted in scrap, and need to remake entire punching pin, it is not only unrestrained
Take material, and affect the manufacturing cycle of template, and since punch shape is unreasonable, the recess got on template is smaller,
Drill bushing cannot be entirely prevented to loosen and fall off, when drill bushing, which falls off, to be lost, it is necessary to reprocess template diamond setting set again, and then influence
The production efficiency of part.
Summary of the invention
The object of the present invention is to provide a kind of template drill bushing punching pin, manufacture material is saved in easy to repair and replacement, effectively anti-
Only drill bushing loosens and falls off.
The technical scheme is that
A kind of template drill bushing punching pin is mainly made of handle 3, formed punch 5 and positioning core axle 6；
The handle 3 is made of cylindrical shaft a and cylindrical shaft b, is structure as a whole, and axis b is located at the bottom of axis a, and two
Person is coaxial, and the diameter of axis a is greater than the diameter of axis b；The top of axis a, which is equipped with, prevents pounding lid 1, and outer surface is equipped with Anti-slip cover 2；Axis b's is outer
Surface is equipped with external screw thread；
The formed punch 5 is sleeved on the outside of axis b positioned at the bottom end of axis a for tubular structure, and the top of 5 inner wall of formed punch is set
There is internal screw thread, matched with the external screw thread of axis b, open washer 4 is equipped between formed punch 5 and axis a；The formed punch 5, one end with
Handle 3 is to be threadedly engaged connection, and the inside of other end end is equipped with conical surface 5-1, conical surface 5-1 and the angle a of the outer wall of formed punch 5 and is
30 °~60 °；
The positioning core axle 6, one end are inserted into the inside of axis b, and the other end extends to the outside of formed punch 5, positioning core axle 6 with
Axis b is coaxial, and positioning core axle 6 plays the role of positioning.
The anti-lid 1 of pounding is hat-shaped structure, and anti-lid 1 and the handle 3 pounded is interference fit connection.
The material of the Anti-slip cover 2 is rubber, and Anti-slip cover 2 and handle 3 are interference fit connection.
The positioning core axle 6 is cylindrical structure, and positioning core axle 6 and handle 3 are interference fit connection.
The beneficial effects of the present invention are: structure of the invention is simple, and it is low in cost, it is easy to disassemble, solve drill bushing loosening
The problem of with falling off, and can sharpen and replace after formed punch abrasion, save manufacture material.
Detailed description of the invention
Fig. 1 is the main view of template drill bushing punching pin.
In figure: 1 prevents pounding lid；2 Anti-slip covers；3 handles；4 open washers；5 formed punches；The 5-1 conical surface；
6 positioning core axles；A angle.
