Abstract
The utility model discloses a tapping chuck which comprises a shaft sleeve (1) and a mandrel (2), wherein an installation handle (3) is arranged at one end of the shaft sleeve (1); one end of the mandrel (2) penetrates into the shaft sleeve (1); a screw tap installation hole (4) is formed at the other end of the mandrel (2); the mandrel (2) is connected with the shaft sleeve (1) through a horizontal rotating shaft (5); and an elastic device is arranged between the inner wall of the shaft sleeve (1) and the outer wall of the mandrel (2). The tapping chuck has the advantages of simple structure and is convenient to use. A threaded bottom hole is guaranteed to be concentric with the screw tap during tapping, and the fracture of the screw tap is prevented due to the adoption of the tapping chuck.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of tap holder that is used for part is carried out hole processing.
Background technology
Tap holder is mainly used in the clamping screw tap carries out screwed hole to part processing.Existing tap holder mainly comprises taper shank, sleeve and tapered sleeve etc., between them for being rigidly connected, when carrying out the tapping operation, if the situation of decentraction between thread Pilot hole and the screw tap will cause the screw tap fracture.
The utility model content
The purpose of the utility model just provides a kind of tap holder that prevents the screw tap fracture.
The purpose of the utility model is to realize through such technical scheme; A kind of tap holder, it comprises axle sleeve and axle, is provided with installing handle at an end of axle sleeve; One end of said axle penetrates in the axle sleeve; The other end in axle is provided with the screw tap installing hole, is connected through horizontally disposed rotating shaft between said axle and the axle sleeve, between the outer wall of the inwall of axle sleeve and axle, is provided with elastic device.
In order to eliminate the non-concentric error of bringing between thread Pilot hole and the screw tap, said elastic device is an O type circle, and said O type circle is provided with in the groove of axle outer wall.
In order to keep balance, said O type circle is two, is respectively arranged with the top and the middle part of axle outer wall.
Rotating shaft comes off in order to prevent to rotate, and said two ends in rotating shaft are respectively arranged with spring collar.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to use, adopt it can guarantee that when tapping, thread Pilot hole is concentric with screw tap, has prevented the fracture of screw tap.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model user mode reference diagram.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: like Fig. 1, shown in 2; A kind of tap holder, it comprises axle sleeve 1 and axle 2, is provided with installing handle 3 at an end of axle sleeve 1; One end of said axle 2 penetrates in the axle sleeve 1; The other end in axle 2 is provided with screw tap installing hole 4, is connected through horizontally disposed rotating shaft 5 between said axle 2 and the axle sleeve 1, between the outer wall of the inwall of axle sleeve 1 and axle 2, is provided with elastic device.
Wherein, said elastic device is an O type circle 6, and said O type circle 6 is provided with in the groove 7 of axle 2 outer walls.
Further, said O type circle 6 is two, is respectively arranged with the top and the middle part of axle 2 outer walls.
The utility model is to use like this: earlier screw tap 10 is penetrated screw tap installing hole 4, through being arranged on fixing with screw tap installing hole 4 corresponding bolts 9 on the axle.The utility model is in tapping process, and when between thread Pilot hole and the screw tap 10 during decentraction, axle 2 will be compressed O type circle 6; O type circle 6 the flexibilities that are compressed through self; Normal tapping is realized in the position of adjustment screw tap and thread Pilot hole, has so also prevented the fracture of screw tap 10.
Said two ends in rotating shaft 5 are respectively arranged with spring collar 8.The purpose of doing like this is in order to prevent axle sleeve 1 and axle 2 when the high speed rotating, and rotating shaft 5 receives action of centrifugal force and comes off.
Claims (4)
1. tap holder; It is characterized in that: it comprises axle sleeve (1) and axle (2); End at axle sleeve (1) is provided with installing handle (3), and an end of said axle (2) penetrates in the axle sleeve (1), is provided with screw tap installing hole (4) at the other end of axle (2); Be connected through horizontally disposed rotating shaft (5) between said axle (2) and the axle sleeve (1), between the outer wall of the inwall of axle sleeve (1) and axle (2), be provided with elastic device.
