Abstract

The utility model relates to an elastic gear shaving clamp. The elastic gear shaving clamp comprises a mandrel with one end fixedly connected with a workpiece and a sliding cover for fixing the workpeice by being matched with the mandrel, wherein elastic sleeves enabling the mandrel and the workpiece to be in matched connection are arranged on the matched contact faces of the mandrel and the workpiece and between the mandrel and the sliding cover. When the type of existing workpieces, especially large-diameter workpeices are subjected to gear shaving machining, due to large size change of inner holes in the previous process, gaps existing in the mandrel positioning influence the gear shaving precision, hole grouping increases the cost, a too small matching gap between the workpiece and the clamp enables clamping to be difficult, and the like. The elastic gear shaving clamp adopts the elastic sleeves to perform centering and clamping and is reliable in positioning, convenient to clamp and low in cost. In addition, the centering and the clamping of the elastic sleeves and pushing of the workpiece end face are achieved by adopting the sliding cover in a double-end-face mode, and the elastic gear shaving clamp has the advantages of being high in positioning accuracy, compact in structure and high in efficiency.

The utility model content
The purpose of this utility model is to overcome the deficiency existed in background technology, proposes a kind of accurate positioning, convenient mounting and clamping, efficiency is high and cost is low elasticity Fixture for Gear-shaving.
For achieving the above object, the utility model adopts following scheme:
A kind of elasticity Fixture for Gear-shaving, comprise the axle that an end is fixedly connected with workpiece and coordinate axle to fix the slip lid of workpiece, on the contact-making surface of described axle and workpiece cooperation, between axle and slip lid, be provided with the resilient sleeve that axle and workpiece are closely connected.
In above-mentioned a kind of elasticity Fixture for Gear-shaving, the end that described axle coordinates with workpiece is provided with frustum, one end face of described resilient sleeve is provided with the cone groove be connected with frustum, and axle is socketed in the cone groove of resilient sleeve by frustum, described slip lid is placed in the other end of resilient sleeve, and holds down mandrel by resilient sleeve.
In above-mentioned a kind of elasticity Fixture for Gear-shaving, be provided with the packing ring of regulating the workpiece useable width between described slip lid and resilient sleeve.
In above-mentioned a kind of elasticity Fixture for Gear-shaving, described axle is provided with the stop screw that runs through resilient sleeve, and the adjustment screw is housed on stop screw.
In above-mentioned a kind of elasticity Fixture for Gear-shaving, described axle is provided with resetting means.Resetting means comprises spring base and spring, and spring base is fixed on the contact-making surface of axle and resilient sleeve.
In above-mentioned a kind of elasticity Fixture for Gear-shaving, described slip lid is provided with large small end face, and small end face compresses resilient sleeve, large end face and workpiece to be machined locking.
In above-mentioned a kind of elasticity Fixture for Gear-shaving, the large end face of described slip lid is elastic thin-wall dish or disc spring film.
The present invention's beneficial effect compared to existing technology is:
1. during for existing this type of workpiece Shaving Process because front in-process hole dimension change is large, large-diameter workpiece especially.In axle location, exist gap affects shaving precision, hole grouping increase cost, with the too small phenomenon that causes the clamping difficulty of fixture fit clearance, the present invention adopts resilient sleeve centering to clamp, and makes that it has advantages of that location is reliable, convenient mounting and clamping, cost be low.
2. adopt the nut check mode for existing ordinary elasticity shell type fixture, clamping is time-consuming and end face run-out is large, the present invention adopts the slip lid Double End to realize that resilient sleeve centering clamps and the push-tight workpiece end face, has that positioning precision is high, compact conformation and a high beneficial effect of efficiency.
The accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model;
Fig. 2 is the lateral view of elastic thin-wall dish slip lid of the present utility model;
Fig. 3 is the local lateral view of butterfly spring slip lid of the present utility model.
Fig. 4 is the cutaway view of slip lid in the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
A kind of elasticity Fixture for Gear-shaving as shown in Figure 1, comprise the axle 1 that an end is fixedly connected with workpiece and coordinates axle 1 to fix the slip lid 4 of workpiece, on the contact-making surface that described axle 1 and workpiece coordinate, between axle 1 and slip lid 4, be provided with the resilient sleeve 2 that axle 1 and workpiece are closely connected.In use, by extruding resilient sleeve 2, it is fully contacted with workpiece, and then guarantee that the precision of workpiece coordinates and location.
In above-mentioned, in order fully to realize above-mentioned technical scheme, center roller 1 and resilient sleeve 2 are done following design: the end that described axle 1 coordinates with workpiece is provided with frustum, one end face of described resilient sleeve 2 is provided with the cone groove be connected with frustum, and axle 1 is socketed in the cone groove of resilient sleeve 2 by frustum, described slip lid 4 is placed in the other end of resilient sleeve 2, and holds down mandrel 1 by resilient sleeve 2.
In above-mentioned, in order to enlarge the scope of application of this device, be provided with the packing ring 3 of regulating the workpiece useable width between described slip lid 4 and resilient sleeve 2, in use the thickness by repair packing ring 3 guarantees that slip lid 4 can fully contact and then guarantee its quality of fit with resilient sleeve 2, so just can make this device adapt to the workpiece processing of different in width and then enlarge its scope of application.
In above-mentioned, described axle 1 is provided with the stop screw 8 that runs through resilient sleeve 2, and adjustment screw 7 is housed on stop screw 8; Described axle 1 is provided with resetting means, and resetting means comprises spring base 6 and spring 5, and spring base 6 is fixed on the contact-making surface of axle 1 and resilient sleeve 2.At work, spring base 6 is used for Flexible Reset cover 2 and is convenient to workpiece loading and unloading, and stop screw 8 is used for preventing that resilient sleeve 2 from coming off.
