Abstract
The utility model discloses a gear tooth grinding positioning tool which comprises a base, a positioning mandrel and a pressure plate, wherein the positioning mandrel is arranged on the base; the pressure plate is arranged on the upper end surface of the positioning mandrel and used for fixing the gear; a reverse annular expansion sleeve is clamped at the outer part of the positioning mandrel; and multiple expansion/contraction slots are arranged on the outer side wall of the expansion sleeve. In the utility model, as an expansion sleeve is arranged between the mandrel and a gear shaft hole, the gap between the mandrel and the gear shaft hole is greatly reduced, the positioning is stable, and the gear processing accuracy is ensured; the expansion sleeve is convenient to assemble and disassemble and difficult to wear in the using process, and has long service life; and moreover, the inventory of the mandrel is reduced, and the cost is lowered.
Description
Technical field
The utility model relates to the gear grinding manufacture field, specifically is a kind of gear grinding positioning tool.
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 positioning tool, and it is poor to solve existing gear grinding jig for positioning locating effect, the problem of troublesome poeration.
The technical scheme of the utility model is:
The gear grinding positioning tool comprises base, is arranged at apotting spindle on the base, is arranged at the pressing plate that is used for fixing gear on the apotting spindle upper surface, and the outside engaging of described apotting spindle has annular expansion set, the lateral wall of expansion set to be provided with a plurality of breathing grooves.
The inwall of described expansion set is the conical surface, and the diameter of the conical surface is for increase from top to bottom gradually.
The sidewall of described expansion set is provided with the breathing hole, and described breathing groove and breathing hole evenly distribute along the expansion set outer ring.
Described pressing plate is provided with locking nut.
The top of described expansion set is provided with the lifting screw.
The inwall of described expansion set is the 1:10 conical surface.
The utility model has guaranteed that through between apotting spindle and gear axis hole, expansion set being set the space reduces positioning stablity greatly between apotting spindle and the gear axis hole; Guaranteed the precision of Gear Processing; And this expansion set easy installation and removal, use is not easy to wear, and the life-span is long; And reduced the axle quantity in stock, reduced cost.
Description of drawings
Fig. 1 is the utilization structure sketch map of the utility model.
Fig. 2 is the longitudinal sectional view of the utility model expansion set.
Fig. 3 is the vertical view of the utility model expansion set.
The specific embodiment
See Fig. 1, the gear grinding positioning tool, comprise base 1, be arranged at apotting spindle 2 on the base 1, be sticked in apotting spindle 2 annular expansion set 3, be arranged at and be used for fixing the pressing plate 4 of gear on apotting spindle 2 upper surfaces and be arranged at the locking nut 5 on the pressing plate;
See Fig. 2, Fig. 3; The inwall of expansion set 3 is the 1:10 conical surface; And the diameter of the conical surface is for increase from top to bottom gradually; Expansion set 3 lateral walls are provided with seven breathing grooves 6 and a breathing hole 7, and seven breathing grooves 6 and a breathing hole 7 evenly distribute along the expansion set outer ring, and the top of expansion set 3 is provided with lifting screw 8.
See Fig. 1, before the clamping, apotting spindle 2 is fixed on the base 1; The T-slot that then base 1 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 2 conical surfaces to beat, guarantee to beat fastening good apotting spindle 2 in 0.01mm, gear 9, expansion set 3, pressing plate 4 are installed then successively; And reinforce with locking nut 5, can begin the roll flute operation.During dismounting, remove locking nut 5 and pressing plate 4 successively, the lifting screw through bolt and expansion set takes out expansion set 3 between the axis hole of apotting spindle 2 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 (endoporus is constant, and cylindrical changes) gets final product under the constant situation of apotting spindle 2.
