Abstract
The utility model provides an abutment sleeve, includes the two steel ball positioning system of sleeve and automatically regulated, the two steel ball positioning system of automatically regulated arrange in the sleeve is inboard, the two steel ball positioning system of automatically regulated include two ball plung and spring, its reasonable in design, and simple structure, convenient operation, the low cost fix a position more accurately, and to a great extent has reduced the drill bit and has ground the probability of failure, has obviously promoted the grinding qualification rate, easily popularization and application.
Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of abutment sleeve positioned for processing drill.
Background technology
Grinding is applied comparatively extensive in grinding machine grinding is produced, and be one of master operation of drilling bit grinding processing, traditional abutment sleeve steadiness still has deficiency, occur relaxed state, precision also has much room for improvement, and bit damage is frequent, cost of idleness, therefore has the necessity improved again.
Therefore, the problems referred to above should be paid attention to and the problem solved in the design and use process of abutment sleeve.
Utility model content
For above-mentioned Problems existing, the utility model provides a kind of structure simple, easy to operate abutment sleeve.
Technical solution of the present utility model is: a kind of abutment sleeve, described abutment sleeve comprises sleeve and automatically regulates two steel ball navigation system, the two steel ball navigation system of described automatic adjustment is placed in inside described sleeve, and the two steel ball navigation system of described automatic adjustment comprises two positioning balls and spring.
Further improvement of the utility model is: the both sides of described sleeve are provided with cross-drilled hole, and two described positioning balls and spring embed in the cross-drilled hole of described sleeve both sides respectively, and described spring one end connects the inwall of described sleeve, and the other end connects described positioning ball.
Further improvement of the utility model is: the volume that described positioning ball is placed in described cross-drilled hole is the 1/3-1/2 of described positioning ball.
A kind of abutment sleeve of the utility model, when drill bit enters sleeve, the positioning ball of both sides is clamp-oned in cross-drilled hole by drill handle part, when the blade of drill bit enters sleeve, the positioning ball of both sides embeds among the groove of drill bit under the elastic force of spring, clamp described drill bit with this, drill bit is located more accurate.
The beneficial effects of the utility model are: a kind of abutment sleeve that the utility model provides, and it is reasonable in design, and structure is simple, easy to operate, low cost, locates more accurate, decrease the probability of drilling bit grinding failure to a great extent, obviously improve grinding qualification rate, be easy to apply.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model;
Wherein: 1-sleeve, 2-positioning ball, 3-spring, 4-cross-drilled hole.
Detailed description of the invention
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, this embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
As shown in the figure, the present embodiment provides a kind of abutment sleeve, technical solution of the present utility model is: a kind of abutment sleeve, described abutment sleeve comprises sleeve 1 and automatically regulates two steel ball navigation system, the two steel ball navigation system of described automatic adjustment is placed in inside described sleeve 1, the two steel ball navigation system of described automatic adjustment comprises two positioning balls 2 and spring 3, the both sides of described sleeve 1 are provided with cross-drilled hole 4, two described positioning balls 2 and spring 3 embed in the cross-drilled hole 4 of described sleeve both sides respectively, described spring 3 one end connects the inwall of described sleeve 1, the other end connects described positioning ball 2, the volume that described positioning ball 2 is placed in described cross-drilled hole 4 is 1/2 of described positioning ball.
A kind of abutment sleeve of the present embodiment, when drill bit enters sleeve 1, the positioning ball 2 of both sides is clamp-oned in cross-drilled hole 4 by drill handle part, when the blade of drill bit enters sleeve 1, the positioning ball of both sides embeds among the groove of drill bit under the elastic force of spring 3, clamp described drill bit with this, drill bit is located more accurate.
The beneficial effect of the present embodiment is: a kind of abutment sleeve that the utility model provides, and it is reasonable in design, and structure is simple, easy to operate, low cost, locates more accurate, decrease the probability of drilling bit grinding failure to a great extent, obviously improve grinding qualification rate, be easy to apply.
