Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of high accuracy auxiliary mould as shown in Figure 1, comprise axle 1, described axle 1 comprises the axle body 1b arranged from left to right, the axle collar 1c that gear 3 to be processed is moved to the left can be limited, for placing the axle journal 1d of gear 3 to be processed, spindle nose 1e, the periphery of described spindle nose 1e has external spiral groove 1f, described spindle nose 1e is socketed with the gland 2 that can slide along it, described gland 2 is the cylinder that left end opening right-hand member is closed, the inwall of described gland 2 has inner spiral groove 2a, the sidewall of described gland 2 right-hand member is provided with through hole 2b, in order to more effective collection and by waste oil and impurity discharge gland 2, as shown in Figure 3, described gland 2 has the cannelure 2d be communicated with described inner spiral groove 2a on the inwall of right-hand member, described cannelure 2d inwall has the through hole 2b running through described gland 2 sidewall, waste oil and impurity are flowed into cannelure 2d and are discharged by through hole 2b, cannelure 2d plays and collects waste oil and impurity and the effect preventing waste oil and impurity backflow.
As shown in Figure 3 and Figure 4, the edge of the left side of gland 2 is inlaid with the permanent magnet 7 of a ring-type, the external diameter of permanent magnet 7 is identical with the external diameter of gland 2, the left side of permanent magnet 7 and the left side of gland 2 coplanar, after machining, permanent magnet 7 can hold the gear machined, and the gear that machines is moved right together along with gland 2, reach the object of quickly discharging material, improve working (machining) efficiency.
As shown in Figure 2, axle 1 is provided with the counterbore being extended to axle body 1b inside by the right side of axle 1, a mandrel 4 is equipped with by the mode of interference fit in counterbore, the left side of mandrel 4 contacts with the bottom surface of counterbore, the right-hand member of mandrel 4 is concordant with the right-hand member of axle 1, mandrel 4 and axle 1 are made from a variety of materials, because mandrel 4 and axle 1 are made from a variety of materials, so after a longer time of use, the deformation extent of mandrel 4 and axle 1 and deformation direction are different, utilize this difference, mandrel 4 is played a supporting role in the inside of axle 1, effectively can slow down the distortion of axle 1, extend service life of the present invention.
During use, gear 3 to be processed is enclosed within axle journal 1d, then axle 1 is fixed on gear shaving machine, advance gland 2 until gear to be processed 3 clamps left, just can treat machining gears 3 and carry out shaving, the taking-up that after shaving completes, taking-up gland 2 just can will machine.Wherein external spiral groove 1f and inner spiral groove 2a coordinate the effect playing the impurity such as oil extraction, exhaust, the tiny iron filings of row, make gland 2 when can easy slide when fit clearance is minimum with spindle nose 1e.
Further, in order to make gland 2 obtain best sliding effect with spindle nose 1e when fit clearance is minimum, as shown in Figures 2 and 3, the rotation direction of described external spiral groove 1f and described inner spiral groove 2a is consistent and pitch is identical.
Further, as shown in Figure 2, described spindle nose 1 right-hand member is provided with bulge loop 1g, and the cross section of the periphery of described bulge loop 1g is semicircle, described bulge loop 1g maximum outside diameter is identical with the size of described gland 2 internal diameter, and waste oil and larger impurity can effectively be shifted onto in cannelure 2d by arranging of bulge loop 1g.
Gear 3 to be processed is compressed in order to make gland 2, as shown in Figure 1, described axle body 1b left side have be positioned at described axle 1 center line on left fixing hole 1a, the right side of described gland 2 have be positioned at described axle 1 center line extended line on right fixing hole 2c, the left thimble of gear shaving machine withstands left fixing hole 1a, utilize gear shaving machine tailstock hydraulic pressure thimble top right fixing hole 2c gland 2 is moved to the left thus compresses gear 3 to be processed, gland 2 can be taken out when obvious gear shaving machine tailstock hydraulic pressure thimble shrinks.Coordinate left fixing hole 1a to measure the distance of steel ball to axle collar 1c by a steel ball when axle is installed in practice, can position according to this distance center roller 1 and adjust stroke and the position of gear shaving machine razor.
Especially, in order to ensure shaving precision, the fit clearance of described gland 2 and described spindle nose 1e is between 0.005 ~ 0.008cm.
Conveniently gear 3 to be processed is loaded axle journal 1d, described axle 1d right-hand member is processed with the chamfering of 5 × 15o, obviously conveniently assembles, and other connecting portion of the present invention is also provided with chamfering, such as the left end place of gland 2 inwall.
The present invention is specially adapted to process central gear.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
