Description
Technical field
The present invention relates to belong to the turning manufacture field of bent axle for compressor of air conditioner, specifically, the present invention relates to a kind of lathe dog, this chuck is used for clamping bent axle and carries out turning.
Background technology
In axle process, require to have higher concentricity, the axle particularly using in present precision instrument is higher to the concentricity requirement of axle, existing process technology is that the axle for the treatment of turning is directly clamped on the claw of lathe chuck, if need to regulate a claw in process, other several jaws also move thereupon, cause center line and the difficult adjustment of lathe spindle axiality of chuck, during lathe High Rotation Speed, as long as the axis of chuck and the axis of axle just do not cause the unstable precision of product concentricity not high on a line, the outer surface of axle has cut.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of convenient lathe dog that regulates chuck concentricity.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of lathe dog, comprise set screw, connecting screw, set screw and alignment pin, also comprise end cap, base, front conical ring, rear conical ring, regulating tank, chute and chuck body, described rear conical ring is enclosed within on the inclined-plane of chuck body one end, alignment pin runs through rear conical ring and is inserted in the regulating tank on chuck body, on the other end neck inclined-plane of chuck body, cover has front conical ring, described chuck body is placed in base, the center line of chuck body overlaps with the center line of base, end cap is joined merga pass connecting screw with base and is connected, end cap bottom is provided with set screw, one end of set screw withstands on front conical ring, the bottom of base is provided with set screw, set screw runs through base and is inserted in the chute on rear conical ring.
Described set screw has four, is inserted in uniformly the four direction of inner cone ring outer surface.
The uniform groove of described this external surface of chuck, groove is parallel with chuck body center line.
The two ends of described chuck body are equipped with groove.
Described groove extends on the conical surface of chuck body.
Adopt technical scheme of the present invention, can obtain following beneficial effect:
Lathe dog of the present invention carries out turning for clamp axis, forward and backward conical ring and the combination of chuck body are arranged, and axle is placed in chuck body, in turning process, as bad in the concentricity of axle and lathe spindle need are by adjusting set screw, and do not need whole axle and chuck to pull down and readjust, chuck and lathe spindle concentricity are easy to adjust, and product concentricity is stable.The combination setting of groove and forward and backward conical ring on chuck body, while making to clamp crankshaft workpiece easy to operate installation simple, bent axle is clamped in and on this chuck, is difficult for deflecting and the problem of sideslip, has guaranteed the precision of product and has improved working (machining) efficiency.

The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
As shown in Fig. 1 ~ 6, the present invention is mainly comprised of end cap 1, set screw 2, base 3, set screw 4, front conical ring 8, rear conical ring 5, alignment pin 6, chuck body 7, connecting screw 9 and alignment pin 6.As shown in Figure 7, fixing upper axle 14 when this lathe dog is mainly used in the lower shaft 13 of turning bent axle 12, due to body bent axle 12 to comprise the special constructions such as eccentric wheel high to the concentricity requirement of axle, general lathe dog is difficult to guarantee concentricity, and this lathe dog has solved existing lathe dog and regulated difficulty and concentricity to hold inaccurate problem.The main body of this chuck is by chuck body 7, front conical ring 8 and rear conical ring 5 form, front conical ring 8 and rear conical ring 5 are arranged on the two ends of chuck body 7, rear conical ring 5 and chuck body 7 are arranged in base 3, the dead in line of the axis of chuck body 7 and base 3, front conical ring 8 is placed in end cap 1, front conical ring 8 and end cap 1 matched in clearance, chuck body 7 outer surfaces are evenly equipped with 6 grooves 71, groove 71 is parallel with the axis of chuck body 7, the setting of groove 71 is convenient at the interior fixed axis of chuck body 7, because groove 71 is to arrange, make whole chuck body 7 there is elasticity, the diameter that prevents axle differs and causes not installing, also play the effect of heat radiation simultaneously, the top of chuck body 7 is also provided with a regulating tank 72, regulating tank 72 is rectangular, regulating tank 72 coordinates with alignment pin 6, alignment pin 6 inserts in regulating tank 72, alignment pin 6 can be in the interior slip of rectangle regulating tank 72, thereby chuck body 7 can only can not be rotated in side-to-side movement, play spacing and effect sliding tray.
Set screw 4 runs through base 3 and is screwed in rear conical ring 5, rear conical ring 5 bottoms are provided with chute 41, set screw 4 can horizontally slip in chute 41, the cooperation of chute 41 and set screw 4 with jointly play the rotation of restriction chuck body 7 in base 3 coordinating of regulating tank 72 and alignment pin 6, and chuck body can be horizontally slipped base 3 is interior, play the effect of holding workpiece.Set screw 2 runs through end cap 1 and is screwed in front conical ring 8, and connecting screw 9 links together end cap 1 and base 3, and the position by set screw 2 is the position of microcartridge body 7 up and down.The tapering of chuck body 7 coordinates with front conical ring 8 and rear conical ring 5, the elasticity of the groove 71 adjustable holding workpieces on chuck body 7 surfaces, during use, with pull bar jointing installation portion 11, upper axle 14 is fixed in axle installation portion 10, and the pull bar that rear conical ring 5 drives by oil cylinder seesaws to clamp and loosen the upper axle 14 in axle installation portion 10, and pull bar compresses forward, unclamp backward, front conical ring 8 can regulate workpiece to beat.During machining lower shaft 13, when the concentricity of axle is different with the concentricity of lathe spindle, the position that only needs adjustment set screw 2 to stretch in front conical ring 8 is position and the concentricity of adjustable clamps body 7, above-mentioned set screw 2 has four, be evenly distributed in the four direction of front conical ring 8, can better regulate like this position of chuck body 7.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
