Abstract
The utility model discloses a pivot grinding frock of slender axles. The machining device comprises a mandrel (1), wherein a center hole (2) is formed in the end face of the mandrel (1), and a machining notch (3) is formed in the center hole (2) of the mandrel (1). Because the utility model discloses be equipped with the centre bore corresponding with the tapering of the processing axle point on the axle point grinding frock of slender axles, the axle point of slender axles rotates at the centre bore of frock, is fixed a position by the centre bore of frock, and the emery wheel can not cause slender axles bending deformation when exerting pressure on the axle point of slender axles and grinding to the axle point of slender axles, and the axle point of slender axles can not take place the displacement, so the axle point size, cylindricity, the runout and the tapering precision that use the utility model discloses a machining of axle point are high, and the runout of its axle point is in 0.001 ~ 0.002mm within range, and each excircle is ground again in the top; the step shaft with the length of 400mm can control the jumping amount within 0.005mm, and can meet the design and use requirements.
Description
Technical field
The utility model relates to the pivot grinding fixture of a kind of grinding fixture, particularly a kind of slender axles.
Background technology
In machining, need sometimes the cylindrical and the pivot of slender axles are carried out grinding, be that a end with axle is clamped on the grinding machine usually to the grinding of axial workpiece, with emery wheel axle is carried out grinding.If processed axle is slender axles, when emery wheel was exerted pressure to slender axles, slender axles can occur bending and deformation.So the beam warp regular meeting that grinding goes out occurs that ovality does not reach requirement, the pivot jerk value is big, causes size, cylindricity, jerk value, the tapering of pivot overproof, can't satisfy design and operational requirement.In order to address this problem, usually when the cylindrical of processing slim axle and pivot, head on the other end of slender axles with frock, prevent to cause mismachining tolerance because of the bending of slender axles.But since the pivot of processed axle some be to be inserted in the centre bore of frock, so can't carry out grinding to the pivot of processed axle.
The utility model content
The purpose of this utility model is, a kind of pivot grinding fixture of slender axles is provided.It is the normal cylindrical of grinding axle not only, also can the grinding pivot, and can guarantee size, cylindricity, jerk value and the tapering precision of pivot, to satisfy design and operational requirement.
The technical solution of the utility model: a kind of pivot grinding fixture of slender axles, comprise axle, the end face of axle is provided with centre bore, and the central hole of axle is provided with machining gap.
In the pivot grinding fixture of above-mentioned slender axles, the oral area of described centre bore is a conical bore, and the bottom is a cylindrical hole.
In the pivot grinding fixture of aforesaid slender axles, the tapering of described conical bore is corresponding with the tapering of processed pivot.
In the pivot grinding fixture of aforesaid slender axles, the angle α of described breach is 90 ° of angles.
In the pivot grinding fixture of aforesaid slender axles, a face of described breach is parallel with the cone side of conical bore.
In the pivot grinding fixture of aforesaid slender axles, the described breach face parallel with the cone side of conical bore is lower than cone side 0.5～0.8mm.
In the pivot grinding fixture of aforesaid slender axles, described axle tail end is provided with footstalk.
In the pivot grinding fixture of aforesaid slender axles, described centre bore is coaxial with footstalk.
In the pivot grinding fixture of aforesaid slender axles, described footstalk is a conical grip, and conical grip is No. 3 cones of Mohs.
In the pivot grinding fixture of aforesaid slender axles, the outside wedge angle rounding of described axle.
Compared with prior art, because the pivot grinding fixture of the utility model slender axles is provided with and the corresponding centre bore of the tapering of processed pivot, central hole in frock, the work breach of emery wheel when being provided with the pivot that is used for slender axles and carrying out grinding, like this when the pivot to slender axles carries out grinding, the pivot of slender axles rotates at the centre bore of frock, located by the centre bore of frock, emery wheel is exerted pressure on the pivot of slender axles and can not be caused slender axles flexural deformation when pivot to slender axles carries out grinding, the pivot of slender axles can not be subjected to displacement, so pivot size that processes with frock of the present utility model, cylindricity, jerk value and tapering precision height, the jerk value of its pivot is in 0.001～0.002mm scope, and each cylindrical is ground on the top again; The step axle of long 400mm, its jerk value can be controlled within the 0.005mm, can satisfy design and operational requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the work schematic diagram during with the pivot of the utility model grinding slender axles.
Being labeled as in the accompanying drawing: 1-axle, 2-centre bore, 3-breach, 4-footstalk, the processed axle of 5-, 6-emery wheel.
The specific embodiment
Be described in further detail below in conjunction with the pivot grinding fixture of drawings and Examples a kind of slender axles of the present utility model, but not as the foundation of the utility model being done any restriction.
Embodiment.A kind of pivot grinding fixture of slender axles, as shown in Figure 1.Comprise axle 1, axle 1 tail end is provided with footstalk 4.Footstalk 4 is a conical grip.Conical grip is No. 3 cones of Mohs.The end face of axle 1 is provided with the centre bore 2 coaxial with footstalk 4, and the oral area of centre bore 2 is a conical bore, and the bottom is a cylindrical hole.The tapering of conical bore is corresponding with the tapering of processed pivot.Axle 1 is provided with machining gap 3.The angle α of breach 3 is 90 ° of angles.A face of breach 3 is parallel with the cone side of conical bore.Breach 3 face parallel with the cone side of conical bore is lower than cone side 0.5～0.8mm.Described axle 1 outside wedge angle rounding.
Process of the present utility model and principle
As shown in Figure 2, add man-hour, head on pivot on the processed axle 5 with the centre bore 1 on the pivot grinding fixture of slender axles of the present utility model, pivot on the processed axle 5 can rotate in the centre bore 1 on frock, pivot on the processed axle 5 exposes from breach 3, and its height that exposes is 0.5～0.8mm.Emery wheel 6 carries out grinding from breach 3 to the pivot on the processed axle 5, when emery wheel 6 contacts with pivot on the processed axle 5 and exerts pressure, because the pivot on the processed axle 5 is by the 1 fixing and location of the centre bore on the frock, pivot on the processed axle 5 can not be subjected to displacement, processing axle 5 can not occur bending and deformation because of pressurized yet, so the pivot size, cylindricity, jerk value and the tapering precision height that process with frock of the present utility model, the jerk value of its pivot is in 0.001～0.002mm scope, and each cylindrical is ground on the top again; The step axle of long 400mm, its jerk value can be controlled within the 0.005mm, can satisfy design and operational requirement.
