Description

PCBN tool bit grinds positioner in batches

Technical Field

The utility model relates to the technical field of PCBN tool grinding, in particular to a batch grinding positioning device for PCBN tool bits.

Background

Polycrystalline Cubic Boron Nitride (PCBN) cutters have high hardness, wear resistance and chemical stability, and are suitable for the requirements of green manufacturing such as high-speed cutting, dry cutting, hard cutting and the like. Because of the reasons of high synthesis cost, high synthesis cavity limitation and the like, PCBN blanks are usually cut into small-size tool bits and welded on a hard alloy matrix, so that the purposes of expanding the application range and reducing the material cost are achieved. PCBN cutting tools use smaller PCBN tips that are typically machined by contact-less laser cutting, and then vacuum brazed to the alloy substrate.

Due to the characteristics of laser processing, the surface of the cut tool bit is provided with an uneven ablation layer, surface grinding is needed to obtain better surface finish, a traditional grinding mode adopts a manual hand-held grinding mode or a single tool bit grinding mode, the grinding efficiency is low, the grinding quality is difficult to ensure, the problems of size consistency and the like are solved, and the quality of subsequent brazing is influenced.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a PCBN tool bit grinds positioner in batches, includes base, left baffle, right baffle and adjusting screw, has seted up the recess that extends to the right-hand member from the left end on the base, and left baffle setting is in the base left side and support to recess left side tip, and right baffle setting is on the base right side to the L-shaped groove has been seted up with the relative position of recess right side tip on the right baffle, adjusting screw passes L-shaped groove from right baffle side and is connected to the base.

Further, a vertical corner is arranged on the base, the groove is of a V-shaped structure, the groove is formed in the corner, and two inner walls of the groove are respectively parallel to two side faces of the corner.

Further, a reserved groove is formed in the bottom of the groove.

Further, the left baffle and the right baffle are fixedly connected with the base through fixing screws.

Further, a C-shaped groove is formed in the bottom of the L-shaped groove.

The beneficial effects of the utility model are as follows:

the tool bit is replaced by adjusting the tightness degree of the pressing plate by using the adjusting screw, so that the tool bit is simple and convenient to replace, and the grinding efficiency is high. The cutter head grinding device has the advantages that the structure is simple, batch grinding of small-size PCBN cutter heads can be realized, the problem of cutter head size consistency caused by manual grinding is avoided, and the cutter head grinding quality is improved.

In the figure: 1-base, 101-recess, 1011-preformed groove, 2-left baffle, 3-right baffle, 301-L shape groove, 3011-C shape groove, 4-adjusting screw, 5-set screw, 6-PCBN tool bit.

Description of the embodiments

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 3, the batch grinding positioning device for PCBN cutter heads provided by the utility model comprises a base 1, a left baffle 2, a right baffle 3 and an adjusting screw 4, wherein a groove 101 extending from the left end to the right end is formed in the base 1, the left baffle 2 is arranged on the left side of the base 1 and abuts against the left end part of the groove 101, the right baffle 3 is arranged on the right side of the base 1, an L-shaped groove 301 is formed in the position, opposite to the right end part of the groove 101, of the right baffle 3, and the adjusting screw 4 penetrates through the L-shaped groove 301 from the side surface of the right baffle 3 and is connected to the base 1.

Be provided with a vertically angular feature 102 on the base 1, recess 101 is V-arrangement structure, and recess 101 is seted up on angular feature 102 to two inner walls of recess 101 are parallel with the both sides face of angular feature 102 respectively, utilize the recess 101 cooperation of vertically angular feature 102 and V-arrangement structure to support tool bit two terminal surfaces, and the grinding of two terminal surfaces of tool bit can be realized to once clamping.
