Description

Gear shaving tool

Technical Field

The utility model belongs to the field of machining, and particularly relates to a gear shaving tool.

Background

Shaving is a common method for processing gears, and the shaving processing is based on the principle that a pair of helical gears with different helix angles are meshed, a shaving cutter and the axis of a gear to be cut are crossed at an angle in space, and the meshing is free generating movement of backlash-free double-face meshing, namely the process of cutting and processing the gear through the rotation of the shaving cutter.

The gear shaving processing needs to fix a gear to be processed on a gear shaving tool, the gear shaving tool in the prior art is composed of a mandrel, an expansion sleeve, a pressing pad and a nut, the nut is tightly screwed by a wrench by hand to tightly press the expansion sleeve during processing so as to ensure that a workpiece is subjected to enough tension force, then the nut is installed on equipment for processing, large physical force is needed to ensure that the torque of the nut is enough, one person can only operate one equipment, the efficiency is low, and the labor intensity is high.

SUMMERY OF THE UTILITY MODEL

The utility model provides a gear shaving tool, which can be used for overcoming the defects in the prior art, can clamp the tool by using a tip, replaces the operation of manually screwing a nut, and achieves the effects of convenient processing and disassembly and labor reduction.

In order to achieve the purpose, the utility model provides the following technical scheme: a gear shaving tool comprises a gear shaving mandrel, wherein a first stop block is fixedly mounted at one end of the gear shaving mandrel; a second stop block is movably arranged at the other end of the gear shaving mandrel; and the other end of the gear shaving mandrel is positioned outside the second stop block and is movably provided with an upper gland of the gear shaving mandrel.

Preferably, an elastic sleeve is movably arranged on the shaving mandrel and positioned between the first stop block and the second stop block; the elastic sleeve is provided with an elastic sleeve upper cover at one side of the second stop block.

Preferably, an elastic sleeve locking spring is further mounted on the elastic sleeve.

Preferably, the number of the elastic sleeve locking springs is more than or equal to two.

Preferably, the first stopper and the second stopper are arranged to be flat relative to the inner side, and are arranged to be conical relative to the outer side.

Compared with the prior art, the utility model has the beneficial effects that:

1. the workpiece is clamped without consuming strong torsion, the workpiece clamping time is saved, and the original single-machine production can realize one-man and three-machine operation; two labors are saved in a single process;

2. the phenomenon that the workpiece is inclined due to the fact that the end face of the nut is not flat in the prior art is avoided;

3. the shaving tooth profile, the tooth direction, the jumping and the accumulated tolerance are reduced, and the shaving precision is improved.

Other features of the present disclosure and advantages thereof will become apparent from the following detailed description of exemplary embodiments thereof, which proceeds with reference to the accompanying drawings.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

Spatially relative terms, such as "above … …," "above … …," "above … … surface," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
