Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, and in particular to a milling cutter for machining the outer diameter of an electric motor housing. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. When machining a motor housing, the housing is machined. This milling cutter is used to machine the outer wall of the motor housing, milling and changing the outer diameter of the motor housing.

[0003] Milling cutters have a simple structure with a fixed shank. When maintaining milling cutters, lubricant needs to be applied to the cutter head and shank, which is not a convenient process. In addition, when milling cutters are not in use, they are usually simply placed flat and cannot be mounted, which makes it easy for the cutter head to come into contact with or bump against the end face on which the cutter is supported. Utility Model Content

[0004] The purpose of this invention is to provide a milling cutter for machining the outer diameter of an electric motor housing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A milling cutter for machining the outer diameter of an electric motor housing includes a cylindrical shank and a cutting head fixed to the right end wall of the shank for milling the end wall of the electric motor housing. The shank has a horizontally opened circular cavity for filling with liquid. A circular hole is provided through the vertical cavity at the end wall of the shank. A through hole is provided through the vertical cavity at the end wall of the shank away from the circular hole.

[0007] Preferably, the outer wall of the tool holder is provided with a side groove at the end wall near the through hole and between the two ends of the round hole, and there are two side grooves.

[0008] Preferably, one through hole and one round hole are provided, with the diameter of the through hole being larger than the width of the side groove and the round hole being smaller than the width of the side groove.

[0009] Preferably, the tool holder has two notches on its central sidewall.

[0010] Preferably, the knife handle has two insertion ports on the left end wall near the notch, one of which is rectangular and the other is circular.

[0011] Preferably, the knife handle has a pair of connecting ports that are connected to the vertical insertion port on the left end wall near the notch, one of the insertion ports being rectangular and the other being circular.

[0012] This utility model has at least the following beneficial effects:

[0013] During maintenance, lubricating oil is poured into the inner cavity of the tool holder. The oil seeps out along the perforation, dripping and sprinkling onto the end wall of the tool tip, lubricating and maintaining the tool tip. This prevents the end of the tool holder away from the tool tip from getting contaminated with lubricating oil. Compared to directly applying lubricating oil to the tool, the lubricating oil distribution area is relatively fixed, keeping the end of the tool holder connected to the machine tool relatively dry and clean for subsequent use. Alternatively, lubricating oil can be poured into the inner cavity before use, allowing it to seep down the side wall of the tool holder to the tool tip, reducing wear on the tool tip and protecting it.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for milling cutters used for machining the outer diameter of motor housings:

[0022] like Figure 1-4As shown, a milling cutter for machining the outer diameter of a motor housing includes a cylindrical shank 1 and a cutter head 2 for milling the end wall of the motor housing fixed to the right end wall of the shank 1. A circular inner cavity 3 for filling liquid is horizontally opened inside the shank 1. A circular hole 6 is provided through the vertical inner cavity 3 at the end wall of the shank 1. A through hole 5 is provided through the vertical inner cavity 3 at the end wall of the shank 1 away from the circular hole 6.

[0023] The outer wall of the handle 1 has two side grooves 4 near the two ends of the through hole 5 and the round hole 6. The diameter of the through hole 5 is larger than the width of the side groove 4, and the diameter of the round hole 6 is smaller than the width of the side groove 4. The central side wall of the handle 1 has two notches 7. The left end wall of the handle 1 near the notch 7 has two insertion ports 8. One of the insertion ports 8 is rectangular and the other is round. The left end wall of the handle 1 near the notch 7 has a pair of connecting ports 9 that are perpendicular to the insertion ports 8. One of the insertion ports 8 is rectangular and the other is round.

[0024] Working principle:

[0025] The end of the tool holder 1 away from the tool head 2 is used to connect to the milling machine. During operation, it performs milling on the outer wall of the motor housing, processes the motor housing, and changes the outer diameter of the motor housing.

[0026] During maintenance, lubricating oil is poured into the inner cavity 3 of the tool holder 1. The oil seeps out along the perforation 5 and drips onto the end wall of the tool head 2, lubricating and maintaining the tool head 2. The end of the tool holder 1 away from the tool head 2 will not be contaminated with lubricating oil. Compared with directly applying lubricating oil to the tool, the lubricating oil delivery and distribution range is relatively fixed, keeping the end of the tool holder 1 connected to the machine tool relatively dry and clean for subsequent use. At the same time, before use, lubricating oil can also be poured into the inner cavity 3. The lubricating oil seeps down along the side wall of the tool holder 1 to the tool head 2, reducing wear on the tool head 2 during processing and protecting the tool head 2.

[0027] The side groove 4, the through hole 5, and the round hole 6 are used to allow lubricant to seep in and guide the lubricant to the outer wall of the handle 1.

[0028] The round hole 6 can also be used for horizontal insertion of cylindrical parts, allowing for simple and quick mounting of the tool holder 1;

[0029] Alternatively, wire, such as iron wire or copper wire, can be threaded through the notch 7, inserted into the slot 8 and the connecting slot 9, and tied to hang the knife handle 1. The slot 8 can be used to insert an L-shaped hook. The slots 8 and 9 are respectively provided with rectangular and round shapes to accommodate different shaped hanging parts, improving the adaptability of the knife handle 1 when it is placed and hung. The knife handle 1 is easy to place and has more ways to place it, preventing the knife handle 1 from being flatly supported on the support surface and causing bumps and damage.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
