Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, specifically a precision milling cutter with an anti-slip texture on the shank. Background Technology

[0002] Precision milling cutters are cutting tools specifically designed for high-precision, high-surface-quality machining requirements. Their core features are the ability to precisely cut minute features, complex surfaces, and difficult-to-machine materials through material innovation, geometric optimization, and process innovation. Polycrystalline diamond has a hardness of HV10000 or higher and is suitable for high-speed milling of non-ferrous metals such as aluminum alloys and carbon fiber composites. Polycrystalline cubic boron nitride has a hardness second only to diamond and can machine hardened steel.

[0003] In the prior art, such as the semi-finishing milling cutter disclosed in CN206326170U, the milling cutter reduces the feed per cutting edge, reduces the load on the tool, and reduces the cutting heat generated, thereby improving the tool life. However, when performing precision milling, a large torque needs to be transmitted, and friction is generated by relying on the radial clamping force of the chuck. The cutting resistance is prone to exceed the maximum static friction force, causing the tool holder to spin freely. This may result in the tool not cutting and the tool holder spinning freely in the chuck, directly leading to overcutting of the workpiece surface or chipping of the tool cutting edge. Utility Model Content

[0004] Given that the existing technology has the problem that when performing precision milling, a large torque needs to be transmitted, and friction is generated by the radial clamping force of the chuck, the cutting resistance is easily exceeded by the maximum static friction force, which can cause the tool holder to spin freely. This may result in the tool not cutting and the tool holder spinning freely in the chuck, which directly leads to overcutting of the workpiece surface or chipping of the tool edge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A precision milling cutter for machining parts with anti-slip texture on the shank includes a fixed shank, a fixed cutter head connected to the front end of the fixed shank, an anti-slip component for anti-slip on the outer surface of the fixed shank, a milling component for milling the workpiece on one side of the fixed cutter head, and a heat dissipation component for heat dissipation of the milling component at the rear end of the fixed shank. The anti-slip component includes a fixing sleeve, anti-slip texture, locking strips, and locking grooves. The fixing sleeve is fitted onto the outer surface of the fixed knife handle. The outer wall of the fixing sleeve is integrally fixed with anti-slip texture. Two locking strips are fixed on the inner side of the fixing sleeve, and one side of each locking strip is inserted into a locking groove.

[0006] As a further embodiment of this utility model: the milling assembly includes a chip removal groove, a fixing seat, a cutting tool, a fixing screw, a threaded groove, and a positioning hole. There are two chip removal grooves, both of which are opened on one side of the fixing head, and a fixing seat is fixed to the inner side of both chip removal grooves.

[0007] As a further improvement of this utility model: a blade is installed on the side wall of the fixing seat, and a fixing screw is installed inside the blade.

[0008] As a further embodiment of this utility model: the end of the fixing screw is threadedly connected to a threaded groove opened on the fixing seat, and the fixing seat is provided with a positioning hole that matches the blade.

[0009] As a further embodiment of this utility model: the heat dissipation assembly includes an inlet pipe, a fixed bearing, a sealing ring, a flow cavity, a connecting pipe, a water spray hole, a fixing strip, a limiting hole, and a limiting bolt. The inlet pipe is connected to the rear end of the fixed tool handle, and the outer surface of the inlet pipe is fitted with a fixed bearing fixed inside the fixed tool handle.

[0010] As a further improvement of this utility model: a sealing ring is fixed at the end of the liquid inlet pipe, and a flow cavity communicating with the liquid inlet pipe is opened inside the fixed knife handle.

[0011] As a further improvement of this utility model: a connecting pipe communicating with the flow cavity is provided on one side of the fixed blade handle, and a water spray hole communicating with the connecting pipe is opened on the outer surface of the fixed blade head.

[0012] As a further embodiment of this utility model: two fixing strips are fixed to the outer wall of the connecting tube and are inserted into the fixed knife handle; a limit hole is opened on the outer surface of the connecting tube; and a limit bolt installed on the fixed knife handle is inserted into the upper end of the limit hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model fixes the milling cutter by placing a fixing sleeve on the outer surface of the fixing tool holder and clamping the machine tool output shaft with the outer surface of the fixing sleeve. The anti-slip texture on the outer surface of the fixing sleeve can effectively prevent slippage. When the anti-slip texture fails, only the fixing sleeve needs to be disassembled and replaced, without replacing the entire milling cutter, thus improving practicality.

[0014] 2. This utility model connects to an external water source through an inlet pipe, allowing coolant to enter the flow chamber through the inlet pipe. The fixed bearing ensures that the inlet pipe will not rotate when the fixed tool holder rotates, and the sealing ring reduces leakage. The coolant entering the flow chamber enters the fixed tool head through the connecting pipe and is sprayed out through the water spray hole on the fixed tool head, thereby cooling the cutting area between the blade and the workpiece.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example 1: Please refer to Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a precision milling cutter for machining parts with anti-slip texture on the tool holder, including a fixed tool holder 1, a fixed cutter head 2 connected to the front end of the fixed tool holder 1, an anti-slip component for anti-slip on the outer surface of the fixed tool holder 1, a milling component for milling the workpiece on one side of the fixed cutter head 2, and a heat dissipation component for heat dissipation of the milling component at the rear end of the fixed tool holder 1. The anti-slip assembly includes a fixing sleeve 3, anti-slip texture 31, retaining strips 32, and retaining grooves 33. The fixing sleeve 3 is fitted onto the outer surface of the fixed tool holder 1. The anti-slip texture 31 is integrally fixed to the outer wall of the fixing sleeve 3. Two retaining strips 32 are fixed to the inner side of the fixing sleeve 3, and each retaining strip 32 has a retaining groove 33 inserted into one side. When the fixing sleeve 3 is fitted onto the outer surface of the fixed tool holder 1, the clamp of the machine tool output shaft clamps and fixes the outer surface of the fixing sleeve 3, thereby fixing the milling cutter. The anti-slip texture 31 on the outer surface of the fixing sleeve 3 effectively provides an anti-slip function.

[0019] Specifically, the milling assembly includes a chip removal groove 4, a fixing seat 41, a cutting tool 42, a fixing screw 43, a threaded groove 44, and a positioning hole 45. There are two chip removal grooves 4, both of which are opened on one side of the fixed cutting head 2, and the fixing seat 41 is fixed on the inner side of both chip removal grooves 4.

[0020] Furthermore, the machine bed drives the fixed tool holder 1 to rotate, which in turn drives the fixed tool head 2 to rotate, so that the cutting tool 42 can perform milling on the workpiece. The chip removal groove 4 is provided to facilitate the removal of waste chips.

[0021] Specifically, a blade 42 is installed on the side wall of the fixing seat 41, a fixing screw 43 is installed inside the blade 42, the end of the fixing screw 43 is threaded to a threaded groove 44 opened on the fixing seat 41, and a positioning hole 45 matching the blade 42 is opened inside the fixing seat 41.

[0022] Furthermore, unscrew the fixing screw 43 to separate the fixing screw 43 from the threaded groove 44 on the fixing seat 41, thereby releasing the fixing of the blade 42. At this time, the blade 42 can be pulled horizontally, and with the cooperation of the positioning hole 45, the blade 42 can be disassembled and replaced.

[0023] In use, connect the fixed tool holder 1 to the output end of the machine tool. First, align the retaining strip 32 on the fixed sleeve 3 with the retaining groove 33, and then push the fixed sleeve 3 horizontally so that the fixed sleeve 3 is fitted onto the outer surface of the fixed tool holder 1. At this time, the clamp of the machine tool output shaft is clamped and fixed to the three surfaces of the fixed sleeve 3, thereby fixing the milling cutter. The anti-slip texture 31 on the outer surface of the fixed sleeve 3 can effectively prevent slippage. When the anti-slip texture 31 fails, only the fixed sleeve 3 needs to be disassembled and replaced separately, without replacing the entire milling cutter, thus improving practicality. The machine tool drives the fixed tool holder 1 to rotate, which in turn drives the fixed cutter head 2 to rotate, so that the insert 42 can perform milling on the workpiece. The chip removal groove 4 facilitates the removal of waste chips. When the insert 42 needs to be replaced, the fixing screw 43 can be unscrewed to separate the fixing screw 43 from the threaded groove 44 on the fixed seat 41, releasing the fixation of the insert 42. At this time, the insert 42 can be pulled horizontally, and with the cooperation of the positioning hole 45, the insert 42 can be disassembled and replaced.

[0024] In summary, when using this precision milling cutter with anti-slip texture, the fixing sleeve 3 is placed on the outer surface of the fixing tool holder 1, and the clamp of the machine tool output shaft is clamped and fixed to the outer surface of the fixing sleeve 3, thereby fixing the milling cutter. The anti-slip texture 31 set on the outer surface of the fixing sleeve 3 can effectively play an anti-slip role. When the anti-slip texture 31 fails, only the fixing sleeve 3 needs to be disassembled and replaced separately, without replacing the entire milling cutter, thus improving practicality.

[0025] Example 2: Please refer to Figures 1-5 This is the second embodiment of the present utility model.

[0026] Specifically, the heat dissipation assembly includes an inlet pipe 5, a fixed bearing 51, a sealing ring 52, a flow chamber 53, a connecting pipe 54, a water spray hole 55, a fixing strip 56, a limiting hole 57, and a limiting bolt 58. The inlet pipe 5 is connected to the rear end of the fixed handle 1. The outer surface of the inlet pipe 5 is fitted with a fixed bearing 51 fixed inside the fixed handle 1. The end of the inlet pipe 5 is fixed with a sealing ring 52. The inside of the fixed handle 1 is provided with a flow chamber 53 that communicates with the inlet pipe 5.

[0027] Furthermore, the inlet pipe 5 is connected to an external water source, allowing coolant to enter the flow chamber 53 through the inlet pipe 5. The fixed bearing 51 ensures that the inlet pipe 5 will not rotate when the fixed tool holder 1 rotates, and the sealing ring 52 can reduce leakage.

[0028] Specifically, a connecting pipe 54 communicating with the flow chamber 53 is provided on one side of the fixed tool holder 1. A water spray hole 55 communicating with the connecting pipe 54 is opened on the outer surface of the fixed tool head 2. Two fixing strips 56 that are inserted and connected to the fixed tool holder 1 are fixed on the outer wall of the connecting pipe 54. A limit hole 57 is opened on the outer surface of the connecting pipe 54. A limit bolt 58 installed on the fixed tool holder 1 is inserted and connected to the upper end of the limit hole 57.

[0029] Furthermore, the coolant entering the flow chamber 53 will enter the fixed cutter head 2 through the connecting pipe 54 and be sprayed out through the water spray hole 55 on the fixed cutter head 2, thereby cooling the cutting area between the blade 42 and the workpiece.

[0030] In use, the inlet pipe 5 is connected to an external water source, allowing coolant to enter the flow chamber 53 through the inlet pipe 5. The fixed bearing 51 prevents the inlet pipe 5 from rotating when the fixed tool holder 1 rotates. The sealing ring 52 reduces leakage. The coolant entering the flow chamber 53 enters the fixed tool head 2 through the connecting pipe 54 and is sprayed out through the water spray hole 55 on the fixed tool head 2, thereby cooling the cutting area between the blade 42 and the workpiece. By unscrewing the limiting bolt 58 on the fixed tool holder 1, the limiting bolt 58 is separated from the limiting hole 57. With the cooperation of the fixing strip 56, the fixed tool head 2 and the fixed tool holder 1 can be disassembled for easy maintenance.

[0031] In summary, when using this precision milling cutter with anti-slip texture, the fixing sleeve 3 is placed on the outer surface of the fixing tool holder 1, and the clamp of the machine tool output shaft is clamped and fixed to the outer surface of the fixing sleeve 3, thereby fixing the milling cutter. The anti-slip texture 31 set on the outer surface of the fixing sleeve 3 can effectively play an anti-slip role. When the anti-slip texture 31 fails, only the fixing sleeve 3 needs to be disassembled and replaced separately, without replacing the entire milling cutter, which improves practicality. In addition, the liquid inlet pipe 5 is connected to an external water source, so that the coolant can enter the flow chamber 53 through the liquid inlet pipe 5. The fixed bearing 51 set in the device prevents the liquid inlet pipe 5 from rotating when the fixing tool holder 1 rotates. The sealing ring 52 can reduce the leakage of liquid. The coolant entering the flow chamber 53 will enter the fixed cutter head 2 through the connecting pipe 54 and be sprayed out through the water spray hole 55 on the fixed cutter head 2, thereby cooling the cutting area between the cutting tool 42 and the workpiece.

[0032] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
