Abstract

The utility model discloses a gear grinding tooling which is composed of a locating shaft and a workpiece clamp, a tubular workpiece clamp is arranged at the upper end part of the locating shaft, the lower part of a gear workpiece is locked in the workpiece clamp, the shaft lower end of the gear workpiece is provided with a locating groove at the center of the top end of the locating shaft, in the way, after the gear workpiece is held, the gear grinding processing can be carried out; the gear grinding tooling is designed , so as to lead the gear grinding period to be short and save material.

Description

A kind of roll flute frock

Technical field

The utility model relates to a kind of roll flute frock, especially employed clamping tooling in the gear grinding process.

Background technology

When present tooth to gear carried out grinding, the normal method that adopts was (as shown in Figure 2): earlier with axially directly being extended for locating shaft on the gear, this locating shaft lower end is fixed on the workbench of grinding, and then gear is carried out grinding; After processing, gear is taken off, block by the locating shaft of other operations again the gear one.

Mainly there is following defective in present gear teeth grinding: 1, because the process principle restriction must be made the technology lengthening, waste of material is big; 2, the technology elongated portion is the roll flute localization part, needs peripheral milling correct grinding sphere, causes the process-cycle long; 3. because the technology lengthening causes the heat treatment batch few.

The utility model content

Technical problem to be solved in the utility model is to provide the roll flute frock of a kind of roll flute processing duration weak point, economical with materials.

The technical solution of the utility model is as follows: design a kind of roll flute frock, it comprises locating shaft, its main points are: described locating shaft is an individual member, be set with the tubular workpiece folder in the upper end of this locating shaft, the utility model can directly carry out needs the gear clamping of roll flute, and carries out roll flute processing, when needing more gear changing, directly the gear that processes is taken off and change gear to be processed then, owing to workpiece clamp can design according to the diameter of axle size of gear shaft, so adaptability is strong.

A kind of optimal way of the present utility model is: described workpiece clamp is taper, and the larger diameter end of this taper work folder is enclosed within on the described locating shaft, so can well gear shaft be clamped good stability.

Another kind of optimal way of the present utility model is: be provided with locating slot in described locating shaft end face central authorities, so the lower end of the gear shaft groove that directly is positioned is spacing, and locating effect is better.

Another optimal way of the present utility model is: described workpiece clamp is a lock nut, and this workpiece clamp is threaded in described locating shaft upper end, and so the replacing of workpiece clamp is convenient.

Beneficial effect: 1. do not need the technology lengthening, reduce material usage; 2. do not need the technology lengthening, improved processing technology, shorten the process-cycle; 3. do not need the technology lengthening, the whole part volume reduces, and has improved the heat treatment batch, reduces cost.
