Description

Multi-section peripheral groove milling cutter

Technical Field

The utility model relates to the technical field of cutter manufacturing, in particular to a multi-section peripheral groove milling cutter.

Background

With the rapid development of electronic circuit technology, high power and high frequency put forward higher requirements on the characteristics and integration level of a circuit board, the printed circuit board needs to be provided with one or more through grooves or interrupted grooves on the side elevation of the circuit board so as to cut off electronic signals of copper foils on the side elevation or be used for embedding and assembling of the side elevation of a precise component, a certain assembling space of electronic components is provided, the thickness of the whole printed circuit board is not influenced, and the integration level of the circuit board is improved. In addition, in some special occasions, the design effect can be achieved by copper plating or other surface treatment of the side grooves so as to control the emission and conduction of electric waves.

The traditional processing method uses a T-shaped cutter, but the T-shaped milling cutter can only process a single groove, and when a plurality of sections of grooves need to be formed, the processing needs to be repeated for a plurality of times, so that the processing time is long, the cost is high, the size positioning precision is poor during repeated processing, and the size stability is poor.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model provides a multi-section peripheral groove milling cutter for solving the problems, which can simultaneously process a plurality of grooves, can accurately position and process each groove, has high positioning precision and improves the processing efficiency.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a multistage formula week groove milling cutter, includes handle of a knife and cutter body, the cutter body links to each other with the handle of a knife, be equipped with at least one spiral helicine cutting edge on the cutter body, it is adjacent be equipped with the chip groove between the cutting edge, be equipped with at least one annular groove on the cutter body, separate into at least two sections with the cutter body.

In a further improvement, the cutting edges on the cutter body in each section have the same helix angle.

In a further improvement, the cutter body and the cutting edge are integrally formed.

Still further, be equipped with the annular groove formation first cutter body, second cutter body and third cutter body on the cutter body, first cutter body, second cutter body and third cutter body radial length equal.

And furthermore, three annular grooves are formed in the cutter body to form a first cutter body, a second cutter body, a third cutter body and a fourth cutter body, the first cutter body, the second cutter body and the third cutter body are used for processing three through grooves in the side face of the workpiece, and the distance between every two adjacent through grooves is equal to the axial width of the corresponding annular groove.

Through the technical scheme provided by the utility model, the method has the following beneficial effects:

the milling cutter body is divided into multiple sections, multiple grooves can be machined simultaneously and respectively, the grooves can be accurately positioned and machined by adjusting the distance between the annular grooves in the milling cutter body, the positioning precision is high, and the machining efficiency is improved.

Drawings

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

fig. 2 is a schematic view of a second embodiment of the present invention.

Detailed Description

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

Example 1

Fig. 1 shows, a milling cutter of all grooves of multistage formula, including handle of a knife 1 and cutter body, the cutter body links to each other with handle of a knife 1, be equipped with at least one spiral helicine cutting edge 21 on the cutter body, it is adjacent be equipped with chip groove 22 between the cutting edge 21, be equipped with three annular groove 23 on the cutter body, separate into four sections with the cutter body, be first cutter body 24, second cutter body 25, third cutter body 26 and fourth cutter body 27 respectively, first cutter body 24, second cutter body 25 and third cutter body 26 equal along axial length. Of course, in other embodiments, the lengths of the first, second and

third tool bodies

24, 25, 26 may be unequal to meet the actual machining requirements.

Specifically, the cutting edges 21 on the first, second, third and

fourth cutter bodies

24, 25, 26 and 27 have the same helix angle.

Preferably, the cutter body and the cutting edge are integrally formed.

When the milling cutter is used for machining, the first cutter body 24, the second cutter body 25 and the third cutter body 26 simultaneously machine three through grooves on the side face of a workpiece, the width of each through groove is equal to the axial length of the corresponding cutter body, the distance between every two adjacent through grooves is equal to the axial width of the corresponding annular groove 23, and the fourth cutter body 27 mills a stepped hole in the workpiece.

Compared with the traditional T-shaped milling cutter, the milling cutter can accurately position and process each groove, has higher positioning precision and improves the processing efficiency. The distance between adjacent through grooves on the cut workpiece is equal to the axial width of the corresponding annular groove, so that the number and the spacing of the annular grooves 23, the helix angle of the cutting edge 21 and the like can be adjusted according to the requirements of the workpiece and the cutting strength in production so as to obtain better processing effect.

Example 2

Different from the embodiment 1, the cutter body is provided with two annular grooves 23, the cutter body is divided into three sections, namely a first cutter body 24, a second cutter body 25 and a third cutter body 26, and the axial lengths of the first cutter body 24 and the second cutter body 25 are equal. Of course, in other embodiments, this may not be equal. The first, second and

third cutter bodies

24, 25, 26 are of equal radial length.

When the milling cutter is used for machining, the first cutter body 24 and the second cutter body 25 simultaneously machine two through grooves on the side face of a workpiece, the width of each through groove is equal to the axial length of the cutter body corresponding to the through groove, the distance between every two adjacent through grooves is equal to the axial width of the corresponding annular groove 23, and the third cutter body 26 mills a stepped hole on the workpiece.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
