Abstract
The invention discloses a drill jig convenient for breaking drilling cuttings, which comprises a jig body, a guide body and a bushing, wherein the jig body is provided with a mounting hole; the guide body is arranged inside the mounting hole; the bushing is arranged between the jig body and the guide body; a drilling cutting baffle cover is arranged at the lower end of the guide body; the drilling cutting baffle cover is trumpet-shaped; spines are arranged inside the drilling cutting baffle cover, and the tip parts of the spines are level with an inner hole of the guide body. According to the drill jig convenient for breaking drilling cutting disclosed by the invention, when the drill generates drilling cuttings in a drilling process, the spines can cut off the drilling cuttings and the drilling cuttings automatically drop off after colliding with the drilling cutting baffle cover, so that a drill is not blocked inside a guide element due to failure to timely break drilling cuttings when the drilling cuttings enter the guide body along with the drill so as to drive the guide body together with the bushing to rotate and abrade the jig body. The service life and the exchange cycle of the drill jig are increased, the production cost is reduced and replacement and maintenance are convenient according to the invention.
Description
Technical field
The present invention relates to a kind of boring grab, in particular a kind of drill bit of can avoiding is stuck in the boring grab of being convenient to chip breaking in the guide because of chip breaking is untimely.
Background technology
Anchor clamps are the important tool of carrying out machine components processing, and are particularly important to the crudy that guarantees part.When machine components need be holed,, just must use boring grab in order to guarantee the perpendicularity in hole.Boring grab in the past shown in accompanying drawing 1, comprises chuck body 1, guide way 2 and lining 3, has installing hole 4 on the chuck body 1, and guide way 2 is arranged in the installing hole 4, and 2 of chuck body 1 and guide waies are provided with lining 3.Though above-mentioned boring grab is simple in structure, processing and manufacturing is easy,, when drill bit produces drilling cuttings if chip breaking is untimely in drilling; Drilling cuttings can get in the guide along with drill bit, and drill bit just is stuck in guide easily, and drill bit drives guide way 2 and rotates together with lining 3; Friction clamp body 1 makes installing hole 4 become big, has influenced the service precision of boring grab; Shorten the replacement cycle of boring grab, increased production cost.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of drill bit of can avoiding and be stuck in the boring grab of being convenient to chip breaking in the guide because of chip breaking is untimely.
Technical solution of the present invention is achieved in that a kind of boring grab of being convenient to chip breaking; Comprise chuck body, guide way and lining; Have installing hole on the said chuck body; Said guide way is arranged in the installing hole, is provided with lining between said chuck body and guide way, and said guide way lower end is provided with retaining bits cover; Said retaining bits cover is horn-like; Be provided with spine in the said retaining bits cover; The endoporus flush of the tip of said spine and guide way.
Preferably, said spine is arranged with two.
Preferably, the upper end of said guide way is arranged with two turnover locating pieces; Said locating piece fixes through pull-out piece spring screw and chuck body.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The boring grab of being convenient to chip breaking of the present invention, because the guide way lower end is provided with retaining bits cover, retaining bits cover is horn-like; Being provided with spine in the retaining bits cover, the endoporus flush of the tip of spine and guide way is when drill bit during at drilling generation drilling cuttings; Spine can cut off drilling cuttings, and drilling cuttings is run into retaining bits cover and will be fallen automatically, makes when drilling cuttings can not get in the guide way along with drill bit; Avoided drill bit to be stuck in the guide because of chip breaking is untimely; Thereby drive guide way and lining and rotate the abrasion chuck body together, increased the service life and the replacement cycle of boring grab, reduced production cost; Simultaneously, because the upper end of guide way is arranged with two turnover locating pieces, locating piece fixes through pull-out piece spring screw and chuck body; During dismounting, the pull-out piece spring screw of at first outwarding winding is dug locating piece then; Get from chuck body from the below of installing hole and to get final product, easy to replace and maintain.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of the boring grab of being convenient to chip breaking of prior art;
Accompanying drawing 2 is the structural representation of being convenient to the boring grab of chip breaking of the present invention;

Accompanying drawing 4 is the exploded view of being convenient to the boring grab of chip breaking of the present invention;
Wherein: 1, chuck body; 2, guide way; 3, lining; 4, installing hole; 5, locating piece; 6, pull-out piece spring screw; 7, retaining bits cover; 8, spine; 9, drill bit.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of boring grab of being convenient to chip breaking shown in accompanying drawing 2; Comprise chuck body 1, guide way 2 and lining 3; Have installing hole 4 on the said chuck body 1, said guide way 2 is arranged in the installing hole 4, and the upper end of said guide way 2 is arranged with two turnover locating pieces 5; Said locating piece 5 fixes through pull-out piece spring screw 6 and chuck body 1; 2 of said chuck body 1 and guide waies are provided with lining 3, and said guide way 2 lower ends are provided with retaining bits cover 7; Said retaining bits cover 7 is horn-like; Be arranged with two in the said retaining bits cover 7 and be provided with spine 8; The endoporus flush of the tip of said spine 8 and guide way.
Of the present invention a kind of boring grab of being convenient to chip breaking shown in accompanying drawing 3, when drill bit 9 when drilling produces drilling cuttings, spine 8 can cut off drilling cuttings; Drilling cuttings is run into retaining bits cover 7 and will be fallen automatically; Make when drilling cuttings can not get in the guide way 2 along with drill bit, avoided drill bit to be stuck in 2 li of guides because of chip breaking is untimely, rotate abrasion chuck body 1 together with lining 3 thereby drive guide way 2; Increase the service life and the replacement cycle of boring grab, reduced production cost.
Of the present invention a kind of boring grab of being convenient to chip breaking shown in accompanying drawing 4 during installation, is at first dug locating piece 5, is inserted in the chuck body 1 from the below of installing hole 4, turns down locating piece 5 then, the pull-out piece spring screw 6 of screwing at last; During dismounting, the pull-out piece spring screw 6 of at first outwarding winding is dug locating piece 5 then, gets from chuck body 1 from the below of installing hole 4 to get final product, and is easy to replace and maintain.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
