Abstract
The utility model relates to the flexible overload protective device of a kind of drilling.Main body comprises inner sleeve, overcoat, locking steel ball and steady pin, and inner sleeve coordinates with machine tool chief axis hole, transmits lathe main-shaft torque; Overcoat coordinates with cutter and chuck, and output torque is to cutter and chuck; Locking steel ball is be connected inner sleeve and overcoat with steady pin, and two parts not only can be moved axially but also not separated.During use; the cooperation conical surface by axial force inner sleeve and overcoat is adjacent to, and transmits a fixed value moment of torsion to cutter, when the stressed sudden change of cutter; cooperation conical surface friction due to inner sleeve and overcoat is large not and produce relative idle running, now cutter stall and the flexibility that realizes cutter crosses cultivation protective effect.
Description
Technical field
The utility model relates to the flexible overload protective device of a kind of drilling.
Background technology
We are (particularly hole, large aperture and Small and Deep Hole Machining) in boring, tapping, fraising and reaming machining, and because the factors such as chip removal is difficult, moment is larger are easily formed, cutter hub bearing load is excessive causes cracking of cutter.This phenomenon not only affects the processing of product, destroys the dimensional accuracy of product.The tool bodies of fracture remains in holes of products, and pole is not easily taken out, and causes product and cutter to scrap.To this problem, entirely with individual feel and the experience of machining hole operator, experienced operator is regular generation breaking phenomenon also.The loss of the cutter that annual problem for this reason causes and product is very large, adopts technological means head it off to become inevitable.
Summary of the invention
For solving the problem, the utility model spy provides a kind of drilling flexible overload protective device.
The flexible overload protective device of a kind of drilling, comprise inner sleeve, overcoat, locking steel ball 1 and steady pin 2, wherein, described inner sleeve is enclosed within overcoat taper hole; In the both sides that described locking steel ball 1 and steady pin 2 are separately positioned on overcoat lower end in aperture, locking steel ball 1 is connected inner sleeve and overcoat with steady pin 2, and inner sleeve and overcoat not only can be moved axially but also not separated.
Described inner sleeve coordinates with machine tool chief axis hole, transmits lathe main-shaft torque.
Described overcoat coordinates with cutter and chuck, and output torque is to cutter and chuck.
During use; the cooperation conical surface by axial force inner sleeve and overcoat is adjacent to, and transmits a fixed value moment of torsion to cutter, when the stressed sudden change of cutter; cooperation conical surface friction due to inner sleeve and overcoat is large not and produce relative idle running, now cutter stall and the flexibility that realizes cutter crosses cultivation protective effect.
The flexible overload protective device of drilling of the present utility model, easy for installation, use simple, flexible overload protection is realized to cutter.

Detailed description of the invention
The flexible overload protective device of a kind of drilling, comprise inner sleeve, overcoat, locking steel ball 1 and steady pin 2, wherein, described inner sleeve is enclosed within overcoat taper hole; In the both sides that described locking steel ball 1 and steady pin 2 are separately positioned on overcoat lower end in aperture, locking steel ball 1 is connected inner sleeve and overcoat with steady pin 2, and inner sleeve and overcoat not only can be moved axially but also not separated.
Described inner sleeve coordinates with machine tool chief axis hole, transmits lathe main-shaft torque.
Described overcoat coordinates with cutter and chuck, and output torque is to cutter and chuck.
Overcoat is loaded in the taper hole of inner sleeve during assembling, and guarantee to rotate freely without stuck phenomenon; Rear loading locking steel ball enters in aperture, and locking steel ball moves axially freely in aperture, is not more than 0.2mm with hole fit clearance; Finally load steady pin, rivet (end rushes 3 points), when the conical surface of overcoat and inner sleeve is not adjacent to, maximal clearance should at gap 0.3 ~ 0.5mm.
Claims (3)
1. the flexible overload protective device of drilling, comprise inner sleeve, overcoat, locking steel ball (1) and steady pin (2), it is characterized in that, described inner sleeve is enclosed within overcoat taper hole; In the both sides that described locking steel ball (1) and steady pin (2) are separately positioned on overcoat lower end in aperture, locking steel ball is connected inner sleeve and overcoat with steady pin, and inner sleeve and overcoat not only can be moved axially but also not separated.
2. the flexible overload protective device of a kind of drilling according to claim 1, it is characterized in that, described inner sleeve coordinates with machine tool chief axis hole, transmits lathe main-shaft torque.
