Abstract

The utility model discloses an expansion sleeve for positioning gear grinding. The expansion sleeve has an annular expansion sleeve structure; the inner wall of the expansion sleeve is a conical surface; the diameter of the conical surface gradually increased from top to bottom; and the outer side wall of the expansion sleeve is provided with a plurality of strip-shaped expansion grooves. The expansion sleeve has a simple structure, is low in manufacturing cost, and is arranged between a positioning mandrel and a gear shaft hole to guarantee that a gap between the positioning mandrel and the gear shaft hole is greatly reduced, the positioning is stable, and the accuracy for the gear machining is guaranteed; and the expansion sleeve is convenient to assemble and disassemble, is difficult to wear during use and has long life.

Description

Expansion set is used in a kind of gear grinding location that is used for
Technical field
The utility model relates to gear grinding positioning tool field, specifically is that expansion set is used in a kind of gear grinding location that is used for.
Background technology
The gear grinding operation is a positioning reference with reference edge and endoporus, and processing method has multiple; The most common employing is axle location roll flute, the axle tolerance generally is controlled at 0~+ 0.01mm between, wherein; The pinion gear aperture tolerance 0~+ 0.025mm between, greatly some gear hole tolerances 0~+ 0.046mm between, that is to say that the hole in the above-mentioned margin of tolerance all is qualified; So just a problem having appearred: if the size in hole is littler than axle, because the cooperation tension can be relatively more difficult when the installation and removal frock, very easily causes the locating surface wearing and tearing; Even the damage locating surface, influence positioning accuracy then; If the size in hole ratio axle is big and near the tolerance upper limit, owing to cooperated pine, influence positioning accuracy equally.The unique way that addresses the above problem is carried out segmentation according to the hole tolerance exactly, and an axle is joined in each segmentation, but can increase the quantity of frock greatly like this, and not only cost is high, and the daily management of frock and maintenance workload are also bigger.
The utility model content
The technical problem that the utility model will solve provides a kind of gear grinding location that is used for and uses expansion set, and it is poor to solve existing axle location roll flute locating effect, and the problem of dismounting difficulty.
The technical scheme of the utility model is:
Expansion set use in a kind of gear grinding location of being used for, and it is to be annular expansion set structure, and the inwall of expansion set is the conical surface, and the diameter of the conical surface is increase gradually from top to bottom, and the lateral wall of expansion set is provided with a plurality of bar shaped breathing grooves.
The sidewall of described annular expansion set is provided with bar shaped breathing hole, and described breathing groove and breathing hole evenly distribute along the expansion set outer ring.
The inwall of described expansion set is the 1:10 conical surface.
The utility model is arranged between apotting spindle and the gear axis hole, has guaranteed that the space reduces positioning stablity greatly between apotting spindle and the gear axis hole; Guaranteed the precision of Gear Processing; And the utility model easy installation and removal, use are not easy to wear, and the life-span is long; And reduced the axle quantity in stock, reduced cost.

Fig. 2 is the vertical view of the utility model.
Fig. 3 is the structural representation that the utility model uses.
The specific embodiment
See Fig. 1, Fig. 2; Expansion set is used in a kind of gear grinding location that is used for; It is annular expansion set structure, and the inwall of expansion set 1 is the 1:10 conical surface, and the diameter of the conical surface is for increase from top to bottom gradually; The lateral wall of expansion set is provided with seven bar shaped breathing grooves 2 and 3, seven the breathing grooves 2 in a bar shaped breathing hole and a breathing hole 3 and evenly distributes along the expansion set outer ring.
See Fig. 3, during the roll flute of axle location, earlier apotting spindle 4 is fixed on the base 5; The T-slot that then base 5 usefulness gear grinding machines is carried is installed on the workbench with bolt; On workbench, utilize the circumference of dial gauge measurement and positioning axle 4 conical surfaces to beat, guarantee to beat fastening good apotting spindle 4 in 0.01mm, gear 6, expansion set 1, pressing plate 7 are installed then successively; And reinforce with locking nut 8, can begin the roll flute operation.During dismounting, remove locking nut 8 and pressing plate 7 successively, the lifting screw through hanging bolt and expansion set takes out expansion set 1 between the axis hole of apotting spindle 4 and gear 6 then.The utility model clamping process is simple, weak point consuming time, and dismounting is simple, and apotting spindle can not wear and tear.For the batch Gear Processing, efficient is high, and in the certain size scope, the bore specification not simultaneously, the corresponding expansion set of processing (the expansion set diameter of bore is constant, and race diameter changes) gets final product under the constant situation of apotting spindle 4.
