Abstract
The utility model relates to a clamping fixture for shaving gears by elastically pressing and centring, comprising a cylinder core shaft, the middle of which is provided with an elastic sleeve which is fixed with the cylinder core shaft through anti-loosing screws, the right side of the cylinder core shaft is covered with a finial pressing cap, and the left side external wall of the finial pressing cap is provided with an elastic pressing sleeve. The beneficial effect of the utility model is that high precision centring eliminates clearance between the core shaft and the inner holes of teeth blank completely, such that the workpieces resetting precision of shaving process is ensured, the difference of a radial round for mounting the workpieces on a machine tool is controlled to be less than 0.008mm, the shaving precision of the workpieces is higher than that of the clamping fixture obviously, working efficiency is improved, and labor strength of operators is reduced.
Description
Technical field
The utility model relates to a kind of Fixture for Gear-shaving that is used for the elastic compression centering of Gear Processing.
Background technology
Development along with technology, the processing of gear is also more and more advanced, precision is also more and more higher, add man-hour at shaving at present,, and adopt the locate mode of elastic expansion-sleeve or static pressure fluidity expansion type mandrel if only lay particular emphasis on the centering error that the geometric eccentricity amount of elimination workpiece location is brought, though problem is solved, but additional hold down gag requires extra clamping, tears open the pine time, and the productive temp with respect to every 2～5min of shaving will make the shaving work efficiency reduce widely.Lose more than gain for improving the locate mode that machining accuracy brings the cost of processing work efficiency loss for this, problem at present existence, a kind of employing high-strength rubber elastic properties of materials compaction techniques is proposed, brand-new elastic compression, elastic centering, the precision height can improve the Fixture for Gear-shaving of the elastic compression centering that is used for Gear Processing of work efficiency.
The utility model content
The purpose of this utility model provides a kind of Fixture for Gear-shaving of the elastic compression centering that is used for Gear Processing, and to add the man-hour work efficiency at shaving low to overcome at present, the deficiency that precision is low.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of Fixture for Gear-shaving that is used for the elastic compression centering of Gear Processing, comprise cylindrical mandrel, the middle part of described cylindrical mandrel is provided with elastic expansion-sleeve, elastic expansion-sleeve is connected and fixed by anti-avulsion screw and cylindrical mandrel, the right side of cylindrical mandrel is with top gland, and the left side outer wall of top gland is provided with the elasticity gland.
The beneficial effects of the utility model are: high-precision centering clamps, eliminated the gap between matched in clearance mandrel and the tooth base endoporus fully, thereby guaranteed the workpiece repetitive positioning accuracy of shaving processing, the radial run-out that workpiece is installed on the lathe can be controlled in the 0.008mm, make the shaving precision of workpiece to be machined apparently higher than cylindrical mandrel's Fixture for Gear-shaving, particularly gear ring circular runout and total cumulative pitch error item, operating efficiency is improved, and can reduce operator's labour intensity.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the Fixture for Gear-shaving of the described a kind of elastic compression centering that is used for Gear Processing of the utility model embodiment.
Among the figure:
1, cylindrical mandrel; 2, elastic expansion-sleeve; 3, anti-avulsion screw; 4, top gland; 5, elasticity gland.
The specific embodiment
As shown in Figure 1, the described a kind of Fixture for Gear-shaving that is used for the elastic compression centering of Gear Processing of the utility model embodiment, comprise cylindrical mandrel 1, the middle part of described cylindrical mandrel 1 is provided with elastic expansion-sleeve 2, elastic expansion-sleeve 2 is connected and fixed with cylindrical mandrel 1 by anti-avulsion screw 3, the right side of cylindrical mandrel 1 is with top gland 4, and the left side outer wall of top gland 4 is provided with elasticity gland 5.
The elastic expansion-sleeve and the elasticity gland of the Fixture for Gear-shaving that the described a kind of elastic compression that is used for Gear Processing of the utility model embodiment is felt relieved adopt the new material polyurethane rubber to make, polyurethane rubber elasticity height, deformational stress is stable, certain flexibility and intensity are arranged, satisfy the circumferentially self centering even distribution that guarantees axial pressing force simultaneously, wearability and good corrosion resistance, stronger oil resistivity (always working in because of Fixture for Gear-shaving in the environment of cutting oil) is particularly arranged, the elastic expansion-sleeve 2 of when concrete the use, workpiece being packed into, put top gland 4, be positioned on the gear shaving machine workbench carriage, it is top to start right side hydraulic pressure, elasticity gland 5 is prior to elastic expansion-sleeve 2 axial compression workpiece (making tooth base end face by calming down the position), and the top deformation resistance that overcomes elasticity gland 5 of hydraulic pressure continues right lateral, finishes centering to elastic expansion-sleeve 2 and clamps, the feed shaving, finish that hydraulic pressure is top behind the shaving returns, take off workpiece, a working cycles finishes.
