Description

Grinding wheel rod structure

Technical Field

The utility model relates to the technical field of grinding wheel rods, in particular to a grinding wheel rod structure.

Background

When the cover plate is processed, a cutter called a grinding wheel rod is used. And (4) fixing the grinding wheel rod through a cutter groove of the CNC equipment so as to process. The depth of a cutter groove of CNC equipment is 30-35mm, the length of a grinding wheel rod cutter handle is generally 30mm, when the grinding wheel rod is installed, the inaccurate size is often held, the installation position is too deep, the coolant cannot be sprayed to a cutter head, the edge breaking and edge burning are caused, and the service life of the grinding wheel rod is greatly influenced. If the installation position is too shallow, the grinding wheel rod cannot be firmly fixed, and the grinding wheel rod can shake in the machining process, so that the product is deformed or has poor size.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, provides a grinding wheel rod structure and solves the problem that the conventional grinding wheel rod is inconvenient to mount.

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

the utility model provides a emery wheel stick structure, includes emery wheel stick handle of a knife, its characterized in that, the fixed snap ring that is equipped with on the emery wheel stick handle of a knife, be equipped with the direction edge on the snap ring, the up end of this snap ring is H to the bottom distance of emery wheel stick handle of a knife, wherein 9mm < H < 10mm, the lower extreme fixedly connected with cutter body of emery wheel stick handle of a knife, be equipped with the tool bit on the cutter body, the cutter body includes that first interval and second are interval, be equipped with the third interval on the tool bit and the fourth interval, the surface of this cutter body and tool bit does not cover has electroplating emery layer, the width of snap ring is W, wherein 1mm < W < 1.5 mm.

Preferably, the upper end of the grinding wheel bar cutter handle is provided with a chamfer.

Preferably, the upper end face of the clamping ring and the grinding wheel rod knife handle are perpendicular to each other.

Preferably, the electroplated emery coated on the outer surfaces of the first interval and the third interval is 1000#, and the electroplated emery coated on the outer surfaces of the second interval and the fourth interval is 400 #.

The utility model has the following beneficial effects: according to the utility model, the clamping ring is designed to be attached to the bottom wall of the cutter groove of the CNC equipment, the length of the grinding wheel bar cutter handle can be just about 10mm, and the design can accurately clamp the position so as to be accurately installed in place at one time.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1. the grinding wheel rod knife handle comprises a grinding wheel rod knife handle body 2, a chamfer angle 3, a clamping ring 4, a guide edge 5, a knife body 6, a knife head 7, a first interval 8, a second interval 9, a third interval 10 and a fourth interval.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, emery wheel stick structure, including emery wheel stick handle of a knife 1, its characterized in that, the fixed snap ring 3 that is equipped with on the emery wheel stick handle of a knife 1, be equipped with direction edge 4 on the snap ring 3, the bottom distance of the up end of this snap ring 3 to emery wheel stick handle of a knife 1 is H, and wherein 9mm < H < 10mm, the lower extreme fixedly connected with cutter body 5 of emery wheel stick handle of a knife 1, be equipped with tool bit 6 on the cutter body 5, cutter body 5 includes first interval 7 and second interval 8, be equipped with third interval 9 and fourth interval 10 on the tool bit 6, the surface of this cutter body 5 and tool bit 6 do not covers has electroplating emery layer, the width of snap ring 3 is W, and wherein 1mm < W < 1.5 mm.

And a chamfer 2 is arranged at the upper end of the grinding wheel rod cutter handle 1. The upper end face of the clamping ring 3 is perpendicular to the grinding wheel rod knife handle 1. The electroplating emery covered on the outer surfaces of the first interval 7 and the third interval 9 is 1000#, and the electroplating emery covered on the outer surfaces of the second interval 8 and the fourth interval 10 is 400 #. During installation, the installation depth of the grinding wheel rod knife handle 1 is 20mm, the length of the grinding wheel rod knife handle is about 10mm, the grinding wheel rod cannot shake, and the knife head can also spray cooling liquid. Through design snap ring 3, make this snap ring 3 laminating in the sword groove diapire of CNC equipment, the length about just can be left about 10mm to emery wheel stick handle of a knife 1 this moment, this design can accurate card accurate position to once accurate installation targets in place.

The above-described embodiments are illustrative of the present invention and not restrictive, it being understood that various changes, modifications, substitutions and alterations can be made herein without departing from the principles and spirit of the utility model, the scope of which is defined by the appended claims and their equivalents.
