Technical Field

[0001] This utility model relates to the field of milling cutters, specifically a chip removal structure and a single-edged spiral milling cutter. Background Technology

[0002] In the field of machining, single-flute helical end mills are commonly used cutting tools, especially suitable for milling metal materials. However, after prolonged use, a large amount of metal chips often accumulate on the end mill shank. If these chips are not cleaned in time, they will not only affect the cutting efficiency of the end mill but may also adversely affect the quality of the machined parts, and even pose a threat to the safety of the machine tool and the operator.

[0003] Traditional cleaning methods often require stopping the machine and using specialized cleaning tools or manual wiping to remove debris. This approach is not only inefficient but also adds extra steps and costs. Therefore, designing a structure that allows for convenient and quick cleaning of debris from the milling cutter shank is particularly important. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chip removal structure, including a plastic collar, which is fitted into a pre-reserved groove. The pre-reserved groove is formed on the shaft of a single-edged spiral milling cutter. The inner ring of the plastic collar has an installation groove, and bristles are fixed to the surface of the installation groove. The inner ring of the plastic collar has a retaining groove, and a rubber ring is inserted into the retaining groove and fitted and fixed to the surface of the pre-reserved groove.

[0006] Preferably, the plastic collar has a circular ring plate structure, the reserved groove is an annular groove, and the height of the plastic collar is equal to the height of the reserved groove.

[0007] Preferably, the outer ring surface of the plastic collar is provided with a side groove, which penetrates the top surface of the plastic collar. There are two side grooves, which are symmetrically distributed about the inner ring opening of the plastic collar. The height of the side groove is less than the height of the plastic collar. After the plastic collar is fitted into the reserved groove, a stop bar is inserted into the inside of the side groove. The top end of the stop bar is fixed to the top surface of the reserved groove, and the height of the stop bar is less than the height of the side groove.

[0008] Preferably, the stop bar is U-shaped, and a rubber clamp is fixed in the groove of the stop bar. The thickness of the rubber clamp is greater than the depth of the stop bar, and the rubber clamp is held between the side groove and the stop bar to produce elastic deformation.

[0009] Preferably, the mounting groove is an annular groove, and the surface of the mounting groove is covered with bristles. When the plastic collar is fitted into the reserved groove, the bristles are deformed under pressure, and the length of the bristles is greater than the distance from the side wall of the mounting groove to the single-edged spiral milling cutter body rod.

[0010] Preferably, the slot is an annular groove, located above the mounting groove, and the outer diameter of the rubber ring is larger than the inner diameter of the plastic collar.

[0011] A single-flute helical end mill, including a chip removal structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The chip removal structure and single-flute spiral end mill proposed in this utility model utilize a plastic collar and a matching brush structure on the single-flute spiral end mill body. When the plastic collar is pulled out of the pre-drilled groove and slides down the shaft, the brush automatically unfolds and effectively removes chips from the shaft, achieving rapid chip removal without stopping the machine or requiring additional tools, greatly improving work efficiency. The ingenious combination of the plastic collar and the pre-drilled groove makes the entire chip removal structure compact and stable, without occupying extra space. Furthermore, chip removal can be achieved with a simple push-pull action, making operation convenient and quick. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1, please refer to Figures 1-7 This utility model provides a technical solution: a chip removal structure, including a plastic collar 1, which is fitted into a pre-reserved groove 3. The plastic collar 1 has a circular ring plate structure, and the pre-reserved groove 3 has an annular groove. The height of the plastic collar 1 is equal to the height of the pre-reserved groove 3. The pre-reserved groove 3 is opened on the rod of the single-edged spiral end mill body 2. A retaining groove 6 is opened at the inner ring opening of the plastic collar 1. A rubber ring 7 is inserted into the inside of the retaining groove 6. The rubber ring 7 is fitted and fixed on the surface of the pre-reserved groove 3. The retaining groove 6 has an annular groove and is located above the mounting groove 4. The outer diameter of the rubber ring 7 is larger than the inner ring opening diameter of the plastic collar 1. The reason for opening the pre-reserved groove 3 on the rod of the single-edged spiral end mill body 2 is to store the plastic collar 1 in the pre-reserved groove 3. That is, the plastic collar 1 is pushed into the pre-reserved groove 3. When the rubber ring 7 is inserted into the retaining groove 6, the plastic collar 1 is prevented from falling off and is limited. At this time, the plastic collar 1 is in a stored state.

[0024] The outer ring surface of the plastic collar 1 is provided with a side groove 8, which penetrates the top surface of the plastic collar 1. There are two side grooves 8, which are symmetrically distributed about the inner ring opening of the plastic collar 1. The height of the side groove 8 is less than the height of the plastic collar 1. After the plastic collar 1 is fitted into the reserved groove 3, a stop bar 9 is inserted into the inside of the side groove 8. The top of the stop bar 9 is fixed to the top surface of the reserved groove 3, and the height of the stop bar 9 is less than the height of the side groove 8. The stop bar 9 is in the shape of a "U". A rubber clamping strip 10 is fixed in the groove of the stop bar 9. The thickness of the rubber clamping strip 10 is greater than the depth of the stop bar 9. The rubber clamping strip 10 is clamped between the side groove 8 and the stop bar 9 and undergoes elastic deformation.

[0025] The reason for opening the side groove 8 on the outer ring surface of the plastic collar 1 is that after the plastic collar 1 is fitted into the reserved groove 3, the stop strip 9 is inserted into the side groove 8 to limit the plastic collar 1 and prevent the plastic collar 1 from rotating in the reserved groove 3. The reason for setting the height of the stop strip 9 to be less than the height of the side groove 8 is that after the plastic collar 1 is fitted into the reserved groove 3, a picking groove is reserved between the bottom end of the side groove 8 and the stop strip 9. After inserting a finger into the picking groove, the plastic collar 1 can be pulled down to remove the plastic collar 1 from the reserved groove 3.

[0026] The inner ring of the plastic collar 1 is provided with an installation groove 4. The surface of the installation groove 4 is fixed with bristles 5. The installation groove 4 is an annular groove and the surface of the installation groove 4 is covered with bristles 5. When the plastic collar 1 is fitted into the reserved groove 3, the bristles 5 are deformed by pressure. The length of the bristles 5 is greater than the distance from the side wall of the installation groove 4 to the rod of the single-edged spiral milling cutter body 2.

[0027] After the plastic collar 1 is pulled out of the reserved groove 3, the reserved groove 3 is squeezed by hand and descends along the rod of the plastic collar 1. During this process, the bristles 5 unfold and sweep the debris in the groove on the rod of the plastic collar 1, thus achieving the removal of debris after the plastic collar 1 has been used.

[0028] Example 2, based on Example 1, proposes a single-edged helical end mill, including a chip removal structure.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
