Description

Hobbing cutter blank processing device

Technical Field

The utility model belongs to the field of hard alloy processing, and particularly relates to a hobbing cutter blank processing device.

Background

The hard alloy is a superhard material, and when the hard alloy hobbing cutter is prepared, a mold for preparing the hobbing cutter is usually prepared, and then pressing sintering or grinding is carried out, but in the pressing sintering process, the required time is long, so that the processing cost is also increased, and the prepared hobbing cutter is also large in deformation.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model discloses a hobbing cutter blank processing device which does not need to manufacture a die and directly cuts, so that the die manufacturing time and cost are saved, the alloy deformation of the manufactured hobbing cutter is smaller, and the precision is improved.

A hobbing cutter blank processing device comprises a bottom plate, wherein sliding blocks are symmetrically arranged on two sides of the lower portion of the bottom plate, and guide rails are arranged at the bottoms of the sliding blocks; one side of the upper part of the bottom plate is provided with a supporting plate, the supporting plate is provided with a through hole, the mandrel is rotatably arranged on the supporting plate, and the hobbing cutter blank is arranged on the mandrel main shaft through a fastening screw.

Further, the mandrel is in a step shape.

Furthermore, a bearing matched with the mandrel is arranged on the supporting plate.

Furthermore, the support plate is correspondingly provided with a small hole at the position connected with the mandrel.

The utility model has the beneficial effects that:

the utility model discloses a hobbing cutter blank processing device, which can save the manufacturing time and cost of a die without manufacturing the die; the processed alloy has small deformation; the processing does not need calcination, thus saving time and calcination cost.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. 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.

Example 1

A hobbing cutter blank processing device comprises a bottom plate 3, wherein sliding blocks 2 are symmetrically arranged on two sides of the lower portion of the bottom plate 3, and guide rails 1 are arranged at the bottoms of the sliding blocks 2; one side of the upper part of the bottom plate 3 is provided with a supporting plate 4, a mandrel 8 is installed on the supporting plate 4 in an optional mode, and a hobbing cutter blank 7 is installed on a main shaft of the mandrel 8 through a fastening screw 6.

The mandrel 8 is in a step shape, the bearing 9 matched with the mandrel 8 is arranged on the supporting plate 4, the hobbing cutter blank can be processed by a milling cutter in a matching mode through the bearing, and the supporting plate 4 is correspondingly provided with a small hole at the position connected with the mandrel 8 and used for being fixedly installed when the aligning mandrel rotates.

The working principle of the device is as follows: and (3) placing the hobbing cutter blank 7 on a mandrel 8, fastening by using a fastening nut 6, and corresponding and fixing the hole on the mandrel 8 and the hole on the support plate 4. Starting the machine to rotate the milling cutter 5, pushing the bottom plate 3 to make the slide block 2 move relatively along the guide rail 1 to complete the processing of one groove and retreat back to the original position. The mandrel 8 is rotated clockwise so that the small hole is aligned with the next hole on the support plate 4 and is aligned and fixed. Repeating the above operations to obtain the final product.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
