Description

A CVD coating device for milling cutters Technical Field

[0001] This utility model relates to the field of CVD coating technology for milling tools, specifically a CVD coating device for milling tools. Background Technology

[0002] CVD coating for milling tools is short for chemical vapor deposition coating. It refers to the deposition of a high-hardness, high-wear-resistant compound coating (such as titanium carbide, titanium nitride, aluminum oxide, etc.) on the tool surface through a chemical reaction of gaseous substances in a high-temperature environment (usually 800-1200℃). This coating is firmly bonded to the tool substrate and can effectively improve the tool's hardness, wear resistance, oxidation resistance and service life. It is suitable for high-speed, high-load milling machining scenarios, and has significant advantages, especially when machining high-hardness materials or workpieces requiring high precision.

[0003] Currently, when applying CVD coatings to milling cutters, the milling cutters need to be continuously heated. This requires placing the milling cutters on a heating structure. However, this makes it difficult to achieve a good coating effect at the contact surface between the milling cutter and the heating structure, thus affecting the quality. Summary of the Invention

[0004] The purpose of this invention is to provide a CVD coating device for milling cutters, so as to solve the problem mentioned in the background art that it is difficult to achieve a good coating effect on the contact surface between the milling cutter and the heating structure.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] Beneficial effects: After the coating on the surface of the milling cutter is completed, the top groove is lowered by the electric lifting rod, and the inserts on both sides are pushed by the electric telescopic rods on both sides, so that the inserts are inserted into two pairs of sockets.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please refer to Figures 1-4. This utility model discloses a CVD coating device for milling cutters, including a coating box 1. The coating box 1 is the main structure of the device and is used to install other structures. The milling cutter is CVD coated in the coating box 1. An air inlet 11 is provided on the top of the coating box 1, and an air outlet 12 is provided at the rear of the coating box 1. Both the air inlet 11 and the air outlet 12 are opened and closed by solenoid valves, that is, the air inlet and outlet pipes are connected through the air inlet 11 and the air outlet 12 to allow air to enter and exit. All electrical equipment in the device is controlled by the same external intelligent controller, which is a conventional technical means for those skilled in the art.

[0024] The coating box 1 is equipped with an installation assembly, which includes a heat-conducting seat 13, a placement groove 23, and a top groove 24. The heat-conducting seat 13, the placement groove 23, and the top groove 24 are all made of heat-conducting materials and are made of the same material. The remaining structures are made of non-heat-conducting materials. The heat-conducting seat 13 is equipped with a heating tube 2. The placement groove 23 is placed on the heat-conducting seat 13. That is, the heating tube 2 includes a temperature detection structure, which is existing technology and can detect the temperature of the heat-conducting seat 13. The milling cutter is placed flat in the placement groove 23. The heat-conducting seat 13 is heated by the heating tube 2, and the heat is transferred to the milling cutter through the placement groove 23, thereby heating the milling cutter.

[0025] An electric lifting rod 32 is installed on the top inner side of the coating box 1. A second motor 33 is installed on the telescopic end of the electric lifting rod 32. The second motor 33 has a built-in protection mechanism that automatically stops rotating when it gets stuck. This is existing technology. A sliding sleeve 34 is installed on the drive shaft of the second motor 33. A sliding post 4 is slidably installed inside the sliding sleeve 34. A stud 41 is installed at the bottom of the sliding post 4. The structure above the stud 41 is collectively referred to as the upper structure. A threaded opening 3 is provided on the inner bottom of the placement slot 23 and the inner top of the top slot 24. The stud 41 is threadedly connected to the threaded opening 3. By connecting the stud 41 to the threaded opening 3, the upper structure can be connected to the placement slot 23 or the top slot 24. 4. Under normal circumstances, the upper structure is connected to the top groove 24, and the electric lifting rod 32 drives the top groove 24 to rise, so that the placement groove 23 is in the open state. When the milling tool is flipped, the electric lifting rod 32 drives the top groove 24 to fall, so that the top groove 24 aligns with the placement groove 23. At this time, the two side pins 5 are inserted into two pairs of sockets 31. The second motor 33 drives the sliding sleeve 34 and the sliding pin 4 to rotate, so that the top groove 24 is disassembled. After the top groove 24 and the placement groove 23 have rotated, the upper structure is connected to the placement groove 23 again, and the placement groove 23 is driven to rise, so that the bottom surface of the milling tool can be coated.

[0026] The coating box 1 has electric telescopic rods 42 on both sides inside. A first motor 43 (a stepper motor) is mounted on the telescopic end of one electric telescopic rod 42. A pin 5 is mounted on the drive shaft of the first motor 43. A mounting post 44 is mounted on the telescopic end of the other electric telescopic rod 42. A rotating sleeve 45 is rotatably mounted on the mounting post 44, and a pin 5 is also mounted on the rotating sleeve 45. Insertion slots 31 are provided on both sides of the placement slot 23 and the top slot 24. The pins 5 are attached and detached from the insertion slots 31, and are pushed by the electric telescopic rods 42 on both sides. Insert the pins 5 into the two pairs of sockets 31. The first motor 43 drives the placement slot 23 and the top slot 24 to rotate 180°, thereby turning the internal milling cutter over and supporting it through the top slot 24. After the upper structure is connected to the placement slot 23, the two side pins 5 are removed. An electric push rod 22 is provided at the bottom of the coating box 1. A heat insulation plate 21 is provided on the telescopic end of the electric push rod 22. The heat conduction seat 13 is installed on the heat insulation plate 21. When the top slot 24 and the placement slot 23 rotate, the electric push rod 22 drives the heat conduction seat 13 to descend. After the rotation is completed, it rises again.

[0027] The working principle of this utility model is as follows: Air inlet and outlet pipes are connected through air inlet 11 and air outlet 12 to allow air to enter and exit. A placement groove 23 is placed on a heat-conducting base 13, and a milling cutter is placed flat in the placement groove 23. The heat-conducting base 13 is heated by a heating pipe 2, and the heat is transferred to the milling cutter through the placement groove 23, thus heating the milling cutter and applying a coating. After the coating is completed, the top groove 24 is lowered by an electric lifting rod 32, and the insertion posts 5 on both sides are pushed by electric telescopic rods 42 on both sides, causing the insertion posts to... The column 5 is inserted into the two pairs of sockets 31. The second motor 33 drives the sliding sleeve 34 and the sliding column 4 to rotate, thereby disassembling the top groove 24 and retracting the electric lifting rod 32. The first motor 43 drives the placement groove 23 and the top groove 24 to rotate 180°, thereby turning the milling cutter inside over. Then the upper structure is connected to the placement groove 23. After the upper structure is connected to the placement groove 23, the two side columns 5 are removed. The upper structure drives the placement groove 23 to rise, thereby coating the bottom surface of the milling cutter and ensuring the coating effect and quality.
