Abstract
The utility model discloses a taper mandrel comprising a mandrel body, wherein the mandrel body is a tapered rod of which the diameter is gradually decreased/increased along an axial direction. By arranging the mandrel into the tapered rod of which the diameter is gradually decreased/increased along the axial extending direction according to the taper mandrel, the operation of automatic centering can be carried out when the taper mandrel is matched with a positioning hole, so that no clearance fit exists between the taper mandrel and the positioning hole, and the occurrence of radial displacement of the mandrel and the positioning hole is prevented so as to improve the processing accuracy; and the taper of the taper mandrel is set as 1:3000 to 1:5000, so that the operation of positioning between the taper mandrel and the positioning hole is more stable, and the phenomenon of swinging between one end of the taper mandrel, which has small diameter, and the positioning hole is prevented.
Description
Technical field
The utility model relates to a kind of axle, and concrete is a kind of tapering axle with tapering.
Background technology
The existing axle employing straight-bar type axle that is used to process the hobboing cutter lip surface because the hobboing cutter centre bore has the different grades of tolerance, adopts the straight-bar type axle when locating hobboing cutter, often has the gap between axle and the hobboing cutter centre bore.When hobboing cutter adds man-hour at horizontal plane, because the gravity effect, making between hobboing cutter and the axle has radial displacement, makes the product that processes be easy to exceed standard because of error accumulation.In addition, also cause road, back roll flute operation to be not easy to reach design standard easily.
Given this, the utility model is intended to existing axle is improved, and through improving mandrel structure, when making axle location hobboing cutter, can not have the gap between axle and the hobboing cutter centre bore, and then improve machining accuracy.
Summary of the invention
The technical problem that the utility model will solve is to propose a kind of tapering axle, through the automatic centering of tapering axle, this tapering axle can realize with locating hole between no gap cooperates, prevent axle and locating hole generation radial displacement, and then the raising machining accuracy.
Realize above-mentioned technical purpose, the tapering axle of the utility model comprises the axle body, and said axle body is the awl bar that diameter in axial direction successively decreases or increases progressively.
Further, the tapering of said axle body is 1:3000 ~ 1:5000.
The beneficial effect of the utility model is: the utility model is set to the diameter bearing of trend awl bar that successively decreases/increase progressively vertically through axle; When the tapering axle is that locating hole cooperates; Can automatic centering; Make that no gap cooperates between tapering axle and the locating hole, prevent axle and locating hole generation radial displacement, and then improve machining accuracy; The tapering of tapering axle is set to 1:3000 ~ 1:5000, makes that the location between tapering axle and the locating hole is more stable, prevents to swing between end that tapering axle diameter is little and the locating hole.
Description of drawings
Fig. 1 is the utility model tapering axle example structure sketch map.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
As shown in Figure 1, be the utility model tapering axle example structure sketch map.The tapering axle of present embodiment comprises axle body 1, the awl bar that said axle body 1 in axial direction successively decreases or increases progressively for diameter.
Present embodiment is set to the diameter bearing of trend awl bar that successively decreases/increase progressively vertically through the tapering axle; When the tapering axle is that locating hole cooperates; Can automatic centering; Make that no gap cooperates between tapering axle and the locating hole, prevent axle and locating hole generation radial displacement, and then improve machining accuracy.
Further improvement as technique scheme; The tapering of said axle body 1 is 1:3000 ~ 1:5000; The tapering of tapering axle is set to 1:3000 ~ 1:5000; Make that the location between tapering axle and the locating hole is more stable, prevent to swing between end that tapering axle diameter is little and the locating hole.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
Claims (2)
1. a tapering axle is characterized in that, comprises the axle body, and said axle body is the awl bar that diameter in axial direction successively decreases or increases progressively.
2. tapering axle according to claim 1 is characterized in that: the tapering of said axle body is 1:3000 ~ 1:5000.
