Abstract
The utility model relates to a novel tapping chuck which comprises a chuck body and a connecting shaft. The chuck body is connected with the connecting shaft through a groove pin, one end of the chuck body is of a spherical structure, two symmetrical and through taper holes are formed in the spherical structure, and the groove pin is inserted into the two taper holes in a penetrated mode; a tightening pin, clamps, an adjusting bolt and an elastic pin are sequentially arranged inside the chuck body, the tightening pin comprises the right clamp and the left clamp; a groove pin, a spring and a spring base are sequentially arranged inside the connecting shaft. By means of the technology, a screw tap is clamped by the special square clamps, the tapping chuck is elastically connected with the screw tap, and the novel tapping chuck has a certain swing angle, so that on the premise that the actual requirement of the tapping process is met, the aims that the breakage possibility of the screw tap is substantially reduced, stable clamping is finally achieved, the angle of the screw tap can be adjusted in the tapping process, and breakage of the screw tap is avoided are accordingly achieved.
Description
Technical field
The utility model relates to mechanical manufacturing field, relates in particular to a kind of novel tap holder.
Background technology
Tapping is a kind of common technique,, in the manufacturing process of various product, generally adopts screw tap as the instrument of tapping technique, and often need to adopt hand-hold power tool to carry out tapping operation.Considering the factors such as hand-held tool Power Limitation and operation, is all generally to attack 12 millimeters of following screw threads.
At present, comparatively popular practical operation is to adopt common drill chuck to clamp screw tap to carry out operation, and the moment of torsion needing due to bore operation is relatively little, and general fluted drill caudal peduncle is circular, drill chuck clamping circle handle; And the moment of torsion that tapping operation needs is relatively large, and general screw tap caudal peduncle is square, if still adopt drill chuck clamping, can cause insufficient clamping force, or the generation of the situation such as easily skid.
In addition, what between drill chuck of the prior art and screw tap, adopt is to be rigidly connected, and cannot adjust the angle of screw tap in tapping operation process, often causes screw tap fracture, thereby affects product quality and operating efficiency.
Summary of the invention
In order to address the above problem, the utility model provides a kind of novel tap holder, possesses clamping firm, can in tapping process, adjust screw tap angle, avoids the advantages such as screw tap fracture.
Above-mentioned a kind of novel tap holder, comprise chuck body and connecting axle, wherein, described chuck body is connected with connecting axle by groove pin, one end near connecting axle on described chuck body is spherical structure, in described spherical structure, be provided with two symmetrical and communicate bellmouths, described groove pin is interspersed in two bellmouths; The inside of described chuck body is disposed with tightening pin, clamp, adjustment bolt and resilient key from the one end away from connecting axle to the one end near connecting axle, and described tightening pin comprises right clamp and left clamp; The inside of described connecting axle is disposed with groove pin, spring and spring base from the one end near chuck body to the one end away from chuck body.
In the said equipment, the quantity of described tightening pin is 2.
In the said equipment, the inclined-plane of described two bellmouths and the angle between vertical line are 30 °.
In the said equipment, the length of described novel tap holder is 78.5mm.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of novel tap holder, adopt Special square clamp to clamp screw tap, and by being connected changing elasticity between tap holder and screw tap, make it have certain pendulum angle, thereby meeting under the prerequisite of tapping technique actual needs, significantly reduced the possibility of screw tap fracture, and it is being firm finally to have reached clamping, can in tapping process, adjust screw tap angle, avoid the objects such as screw tap fracture.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of novel tap holder in the utility model;
Fig. 2 is the front view of novel tap holder in the utility model;
Fig. 3 is the A-A profile of novel tap holder in Fig. 2;
Fig. 4 is the B-B profile of novel tap holder in Fig. 2.
the specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2, the utility model has been recorded a kind of novel tap holder, comprise chuck body 1 and connecting axle 8, and chuck body 1 is connected with connecting axle 8 by groove pin 7, by one end near connecting axle 8 on chuck body 1, be spherical structure simultaneously, and in spherical structure, be provided with 2 symmetrical and communicate bellmouths (not marking in the drawings), then groove pin 7 is interspersed in two bellmouths.
Preferably, the inclined-plane of two bellmouths and the angle between vertical line are 30 °, by these 2 bellmouths, groove pin 7 can be realized 15 ° with interior spinning movement compared to vertical line, with this, having realized screw tap is connected with the elasticity between chuck, thereby meeting under the prerequisite of tapping technique actual needs, significantly reducing the possibility of screw tap fracture.
Further, the internal structure of above-mentioned chuck body 1 as shown in Figure 3 and Figure 4, be specially from the one end away from connecting axle 8 and be disposed with two tightening pins 2, clamp, adjustment bolt 4 and resilient key 6 to the one end near connecting axle 8, and clamp comprises right clamp 3 and left clamp 5; As seen from Figure 3, the jaw of right clamp 3 and left clamp 5 is all designed to rectangular configuration, then by adjusting bolt 4, realizes screw tap the locking of clamping different size, with this, solves the problem that screw tap side's spindle clamp is held; And left clamp 5 and right clamp 3 are designed to respectively left-handed and fine thread dextrorotation, adjusting equally bolt 4 is also left-handed, a dextrorotation cooperation, to facilitate adjustment.
Preferably, the length of the novel tap holder in the utility model is 78.5mm.
Meanwhile, in the inside of connecting axle 8, from the one end near chuck body 1, to the one end away from chuck body 1, be disposed with groove pin 7, spring 9 and spring base 10.
Preferably, consider the wear problem of left clamp 5 and right clamp 3, in the present embodiment, selected to make via the high standard material of Technology for Heating Processing, to improve wearability.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
