Description

Technical Field

[0001] This utility model belongs to the field of cutting tool manufacturing technology, specifically relating to a multifunctional drilling double-layer milling cutter. Background Technology

[0002] Milling cutters are a common tool for machining workpieces on machine tools. Currently, when machining products with hole structures and upper and lower planes, most manufacturers use the method of drilling holes first and then milling the upper and lower planes separately. This method is inefficient, requires a large number of tools, and the machining accuracy will decrease due to multiple tool changes. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a multifunctional drilling double-layer milling cutter to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A multifunctional drilling double-layer grooving cutter is provided, comprising a grooving cutter body, the tail end of which is connected to a machine tool spindle, and the head end of which is sequentially connected to a first cutter head, a thickness control shim, a second cutter head, and a drill bit along the axial extension direction of the machine tool spindle. The second cutter head, the thickness control shim, and the first cutter head are locked together by a cutter head locking nut, and the drill bit is locked together by a drill bit locking nut.

[0006] As described in the multi-functional drilling double-layer milling cutter, the outer diameter of the first cutter head is larger than the outer diameter of the second cutter head.

[0007] As described in the multi-functional drilling double-layer milling cutter, the first cutter head is a multi-tooth cutter head.

[0008] As described in the multi-functional drilling double-layer milling cutter, the second cutter head is a grooving cutter head.

[0009] The beneficial effects of this utility model's technical solution are:

[0010] It integrates the dimensional requirements of the processed product and combines three different shapes of cutting tools, enabling the combination of three different types of cutting tools with different machining directions, thereby improving machining efficiency and machining accuracy.

[0014] The terms “utility model” and “this utility model” used in this specification are intended to broadly refer to all subject matter of this specification and any of the following patent claims. Statements containing these terms should not be construed as limiting the subject matter described herein or limiting the meaning or scope of any of the following patent claims. Furthermore, this specification does not attempt to describe or limit the subject matter covered by any claim of any particular component, paragraph, statement, or drawing of this application. The subject matter should be understood with reference to the entire specification, all drawings, and any of the following claims. This utility model may have other embodiments and be practiced or implemented in other ways. Moreover, it should be understood that the wording and terminology used herein are for illustrative purposes and should not be considered limiting.

[0015] The details of the present invention will now be discussed with reference to the accompanying drawings, which are illustrated by way of example only. In the drawings, similar features or components may be labeled with the same reference numerals.

[0016] The use of the terms "comprising," "having," and "including," and variations thereof, herein means to include the items listed herein, their equivalents, and additional items. While reference may be made in the description of the drawings to directions such as above, below, upward, downward, backward, bottom, top, front, rear, etc., for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the invention in any form. Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0017] See Figure 1 As shown, the multifunctional drilling double-layer milling cutter of this utility model includes a milling cutter body 1. The tail end of the milling cutter body 1 is connected to the machine tool spindle 2. The head end of the milling cutter body 1 is connected in sequence with a first cutter head 3, a thickness control shim 4, a second cutter head 5 and a drill bit 6 along the axial extension direction of the machine tool spindle 2. The second cutter head 5, the thickness control shim 4 and the first cutter head 3 are locked by a cutter head locking nut 7, and the drill bit 6 is locked by a drill bit locking nut 8.

[0018] In a preferred embodiment, the outer diameter of the first cutter head 3 is larger than the outer diameter of the second cutter head 5.

[0019] Furthermore, the first cutter head 3 is a multi-tooth cutter head, and the second cutter head 5 is a grooving cutter head. The multi-tooth cutter head and the grooving cutter head are the main cutting parts on the cutter body. The drill bit 6 is a carbide drill bit, which is the main cutting tool used for drilling. The milling cutter body 1 is the main component that connects the machine tool spindle 2 and the cutting edge and bears the cutting force during cutting.

[0020] The thickness control shim 4 is mainly used to control the distance between the multi-tooth cutter head and the grooving cutter head 5. The outer diameter of the multi-tooth cutter head, the outer diameter of the grooving cutter head, and the distance between the two cutter heads are set according to the parameter requirements of the actual processed product.

[0021] When using this tool, you can first mill the upper and lower machined surfaces of the product, lift it up, and then perform drilling on the product, which improves processing efficiency and accuracy.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
