Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a milling cutter with a chip removal function. Background Art

[0002] A milling cutter is a cutting tool used for metal processing and is widely used in milling. A disc milling cutter is a specially shaped milling cutter, usually in the shape of a disc with the blade located on the outer edge. It is often used for processes such as face milling and slot milling. The design of the disc milling cutter enables it to cover a larger working area during processing, making it suitable for processing flatter surfaces or rough processing. In the process of using a milling cutter for processing, a large amount of debris is often generated and sticks to the milling cutter and the workpiece surface, which can easily reduce the accuracy of the milling machine and thus reduce the quality of the product. Therefore, we need a milling cutter that is easy to remove chips to improve product quality.

[0003] A wear-resistant milling cutter in the prior art (Announcement No.: CN220612426U) can absorb and clean waste chips discharged from the surface of the workpiece and the cutter head through a magnet block, and can use a cleaning brush to clean the surface of the workpiece, making the workpiece surface cleaner and tidier, thereby reducing the impact of waste chips on the milling process of the workpiece. However, the surface of the milling cutter itself will still adhere to and accumulate material debris due to the influence of the magnet, which can easily damage the surface of the workpiece being processed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a milling cutter with a chip removal function.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A milling cutter with a chip removal function comprises a milling cutter body, a plurality of chip removal grooves are circumferentially provided on the surface of the milling cutter body, a chip breaking mechanism is provided on the top of each chip removal groove, a turntable for connecting the chip breaking mechanism is rotatably mounted on the top of the milling cutter body, an adapter plate is fixedly mounted in the middle of the top of the milling cutter body, an annular groove is provided on the circular arc surface of the adapter plate, a plurality of avoidance holes penetrating the outer surface of the adapter plate are evenly provided on the bottom of the annular groove, an adjusting ring is rotatably mounted in the annular groove, a plurality of second connecting rods are evenly fixedly mounted on the bottom of the adjusting ring, and the bottom ends of the plurality of second connecting rods respectively pass through the plurality of avoidance holes and are fixedly mounted to the top of the turntable.

[0007] As a further solution of the present invention, the chip breaking mechanism includes a chip breaker, a slider and a first connecting rod. One end of the first connecting rod is rotatably mounted on the top of the turntable, and the other end of the first connecting rod is rotatably mounted on one side of the slider. A chip breaker is fixedly mounted on the top of the slider, and one side of the chip breaker is provided with multiple cutting edges inclined downward.

[0008] As a further solution of the present invention, a plurality of sliding grooves adapted to the slider are evenly opened on the top of the milling cutter body in a circular shape, and the plurality of sliders are slidably installed in the plurality of sliding grooves respectively, and avoidance grooves for avoiding the chip breaking mechanism are opened around the bottom of the adapter plate.

[0009] As a further solution of the present invention, a transfer shaft is provided in the middle of the top of the transfer plate, the transfer shaft and the transfer plate are an integrated structure, and each of the avoidance holes is an arc-shaped waist groove structure.

[0010] As a further solution of the present invention, the outer arc surface of the adjustment ring is provided with an anti-slip pattern, the top of the adjustment ring is provided with a plurality of threaded blind holes evenly distributed around the circumference, the top of the adapter plate is provided with four through holes evenly distributed around the circumference, a fastening bolt is slidably inserted into each of the through holes, and the plurality of fastening bolts are inserted into the corresponding threaded blind holes and threadedly connected thereto.

[0011] As a further solution of the present invention, a plurality of first heat dissipation holes are evenly arranged in a circle on the top of the adapter plate and pass through its outer surface. Second heat dissipation holes connected to the first heat dissipation holes are arranged in each chip groove on the surface of the milling cutter body. The second heat dissipation holes are T-shaped. An anti-suction groove is provided at the bottom of the milling cutter body to prevent the generation of air pressure suction, and the anti-suction groove is connected to the second heat dissipation holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up a chip breaking mechanism, when the milling cutter body is undergoing machining, the generated chips go upward through the chip discharge groove, are cut by the chip breaker in the chip breaking mechanism, and then thrown out to the surroundings of the equipment. The cut chips are better discharged from the milling cutter body, avoiding the accumulation of chips on the surface of the milling cutter body, thereby affecting the accuracy of the milling cutter body in machining the workpiece, and improving the quality of the processed product;

[0014] 2. By setting an adjusting ring, loosen all the fastening bolts and then rotate the adjusting ring. The adjusting ring drives the turntable to rotate through multiple second connecting rods, and the turntable drives the corresponding sliders to slide on the surface of the milling cutter body through multiple first connecting rods, thereby adjusting the extension distance of the chip breaker. This allows it to adapt to the different depths of the cutting chips entering the chip groove when the milling cutter body is processed with different cutting amounts, and it can still effectively cut off the chips, thereby improving the practicality of the equipment.

The bottom ends of the plurality of second connecting rods 11 respectively pass through Multiple avoidance holes 302 are fixedly installed on the top of the turntable 10, and the chip breaking mechanism 2 includes a chip breaker 201, a slider 202 and a first connecting rod 203. One end of the first connecting rod 203 is rotatably installed on the top of the turntable 10, and the other end of the first connecting rod 203 is rotatably installed on one side of the slider 202. A chip breaker 201 is fixedly installed on the top of the slider 202, and one side of the chip breaker 201 is provided with multiple cutting edges inclined downward. A plurality of slide grooves 12 that are compatible with the slider 202 are evenly opened on the top of the milling cutter body 1. Multiple sliders 202 are respectively slidably installed in the multiple slide grooves 12, and avoidance grooves for avoiding the chip breaking mechanism 2 are opened around the bottom of the adapter plate 3.

[0026] During use, by setting up a chip breaking mechanism 2, when the milling cutter body 1 is undergoing machining, the generated chips go upward through the chip discharge groove, are cut by the chip breaker 201 in the chip breaking mechanism 2, and are thrown out to the surroundings of the equipment.

[0027] In this embodiment, an adapter shaft 4 is provided in the middle of the top of the adapter plate 3. The adapter shaft 4 and the adapter plate 3 are an integrated structure.
