Description

Technical Field

[0001] This invention relates to the field of milling equipment technology, specifically to a multi-angle machining device for PCD turning tools and its usage method. Background Technology

[0002] PCD turning tools are turning tools made of polycrystalline diamond. Polycrystalline diamond is an ultra-hard material formed by sintering many tiny diamond crystals under high temperature and pressure. It has extremely high hardness and wear resistance, second only to single-crystal diamond, but with better toughness and relatively lower cost. PCD turning tools are mainly used to process materials with high hardness and high wear resistance, such as aluminum alloys, carbon fiber composites, and glass fiber reinforced plastics. They are widely used, especially in aerospace, automotive manufacturing, and electronics. They can achieve high-precision and high-efficiency cutting, reduce tool wear and replacement frequency, and improve production efficiency and machining quality. A multi-angle machining device for PCD turning tools is a device used to improve the machining flexibility and accuracy of PCD turning tools. It typically includes multiple adjustable tool holders or tool posts, which can adjust the angle and position of the tool according to different machining requirements. This device can achieve multi-angle cutting of complex-shaped workpieces, improve machining efficiency and quality, and is especially suitable for high-precision machining fields such as aerospace and automotive manufacturing. When machining multiple PCD turning tools, it is usually necessary to fix these tools first. The traditional method is to fix the PCD turning tools one by one. After fixing, the angle of each turning tool is adjusted and ground. This method of fixing and adjusting the angle of each turning tool one by one is cumbersome and prone to operational errors, thus increasing the complexity of operation and the probability of errors. Therefore, in order to address the above problems, a multi-angle machining device for PCD turning tools and its usage method are proposed. Summary of the Invention

The clamping block, insert block, and stop block are an integral fixed structure. A second ball groove is formed between the clamping block and the stop block. A guide rod and a spring are fixedly connected to the upper end of the clamping block. The rotating assembly includes a second ball block. A second tool-fixing groove is formed at the upper end of the second ball block. A transmission column is fixedly connected to the inner side of the second ball block. A second bevel gear is fixedly connected to the end of the transmission column away from the second ball block.

[0005] As a further optimization of the present invention, the machine tool assembly includes a base platform, and a milling device and a ramp are fixedly connected to the top of the base platform, wherein the upper end of the ramp platform is an inclined structure.

[0006] As a further optimization of the present invention, the bottom end of the clamping block is an inclined structure, and the upper end of the clamping block is attached to the lower end of the slope platform.

[0008] As a further optimization of the present invention, wherein: the insert block and the shaft hole are provided with a shaft hole inside, and the shaft hole is connected to the second ball groove.

[0009] As a further optimization of the present invention, wherein: a ball bearing is fixedly connected to the outer side of the second bevel gear, the transmission column is rotatably connected to the inside of the shaft hole through the ball bearing, the transmission column extends out of the inside of the shaft hole, the second ball block rotates inside the second ball groove, and a blade body is embedded and installed inside the second fixed blade groove.

[0010] As a further optimization of the present invention, a second servo motor is fixedly connected to the inner side of the turntable, and a first bevel gear is fixedly connected to the end of the main shaft of the second servo motor. The axis of the second servo motor, the axis of the first bevel gear, and the axis of the turntable are vertically coincident.

[0011] As a further optimization of the present invention, the first ball block has a first fixed groove at its lower end, a rotating ring is fixedly connected to the outside of the first ball block, and the first ball block is magnetically attracted to the turntable.

[0012] As a further optimization of the present invention, the guide rod is slidably connected inside the guide hole, the upper end of the spring is fixedly connected to the bottom end of the turntable, the size of the insert block matches the size of the storage slot, and the insert block and the storage slot are vertically aligned.

[0013] A method for using a multi-angle machining device for PCD turning tools; Step 1: When fixing the blade body, multiple blade bodies are placed inside the second blade fixing groove. The first servo motor drives the drive column to rotate, the drive column drives the turntable to rotate, and the turntable drives the fixing component and the rotating component to rotate as a whole. The spring force causes the clamping block to move away from the turntable. The clamping block and the ramp are both inclined structures. When the clamping block rotates, it gradually moves upward. The clamping block drives the guide rod to move upward. The guide rod slides inside the guide hole. The cooperation between the clamping block and the turntable compresses the spring. The movement of the clamping block drives the insert block and the stop block to move upward. The insert block is inserted into the inside of the storage groove. The top of the stop block is in close contact with the bottom of the turntable. The first blade fixing groove opened by the first ball block and the second blade fixing groove opened by the second ball block have the function of clamping the blade body. Step 2: When the angle is adjusted during the machining of the tool body, the clamping block drives the rotating component to move upward, the second bevel gear meshes with the first bevel gear, the second servo motor drives the first bevel gear to rotate, the first bevel gear drives multiple second bevel gears to rotate simultaneously, the second bevel gears then drive the transmission column to rotate, the transmission column rotates inside the shaft hole through ball bearings, the transmission column drives the second ball block and the tool body to rotate, the second ball block squeezes the first ball block, the first ball block rotates inside the first ball groove through the rotating ring; Step 3: When the tool body is removed, the second servo motor controls the rotation angle of the second bevel gear. The upper end of the second ball block is flush with the upper end of the stop block, and the bottom end of the first tool fixing groove is flush with the bottom end of the turntable. The first servo motor is started in reverse, and the fixing component and the rotating component rotate as a whole. When the clamping block moves, the spring force causes the clamping block to move downward, and the second ball block moves away from the first tool fixing groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting up a ramp, a support assembly, a turntable, and a fixing assembly, the device can simultaneously fix multiple PCD turning tools, which significantly improves operating efficiency, reduces operating difficulty and error rate.

In this invention, through the arrangement of the first ball groove, the first ball block, and the rotating assembly, the device can achieve convenient and stable tool angle adjustment during processing. It can simultaneously adjust the angles of multiple PCD turning tools, ensuring the consistency of the angle of each tool, thereby improving processing accuracy and quality. This angle adjustment method is particularly suitable for large-scale processing operations, significantly improving processing efficiency, reducing operational difficulty, and enhancing ease of use and reliability. 3. In this invention, the device can quickly release and remove multiple PCD turning tools simultaneously through the spring, the second ball block, and the second tool fixing groove, avoiding the tedious process of disassembling them one by one in the traditional way, greatly shortening the tool replacement time and improving work efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] Please see Figures 1-8 The present invention provides a technical solution: A multi-angle machining device for PCD turning tools and its usage method include a machine base assembly 1, a support assembly 2 fixedly connected to the upper end of the machine base assembly 1, an angle control assembly 3 fixedly connected to one end of the support assembly 2, a fixing assembly 4 installed inside the angle control assembly 3, and a rotating assembly 5 rotatably connected inside the fixing assembly 4. The angle control assembly 3 includes a turntable 31, with a receiving groove 32 and a first ball groove 33 opened inside the turntable 31, and a first ball block 34 attached to the inside of the first ball groove 33. The fixing assembly 4 includes a clamping block 41, and the clamping block 41, the insert block 43, and the stop block 46 are an integral fixed structure. The clamping block 41 and the stop block 46 are connected to a second ball groove 42. A guide rod 44 and a spring 45 are fixedly connected to the upper end of the clamping block 41. The rotating assembly 5 includes a second ball block 51, with a second tool fixing groove 52 opened at the upper end of the second ball block 51. A transmission column 53 is fixedly connected to the inside of the second ball block 51, and a second bevel gear 54 is fixedly connected to the end of the transmission column 53 away from the second ball block 51.

[0020] As a further implementation of this solution, the machine tool assembly 1 includes a base platform 11. A milling device 12 and a ramp 13 are fixedly connected to the top of the base platform 11. The upper end of the ramp 13 is an inclined structure, and the bottom end of the clamping block 41 is an inclined structure. The upper end of the clamping block 41 is in contact with the lower end of the ramp 13. Through the above arrangement, it can be closely in contact with the inclined structure at the bottom of the clamping block 41, providing reliable support for the stable movement of the clamping block 41. When the clamping block 41 moves upward, it can be guided by the inclined surface to gradually move the clamping block 41 upward, thereby compressing the spring 45 and providing stable power for subsequent tool fixing and angle adjustment, thus enhancing the reliability and consistency of the device. As a further implementation of this solution, the support assembly 2 includes a frame plate 21. The upper end of the frame plate 21 is fixedly connected to the housing of the first servo motor 22. A through hole is opened on the inner side of the frame plate 21. A drive column 23 is fixedly connected to the end of the main shaft of the first servo motor 22. The drive column 23 is rotatably connected inside the frame plate 21. The bottom end of the frame plate 21 is fixedly connected to the top end of the base platform 11. The bottom end of the drive column 23 is fixedly connected to the top end of the turntable 31. Through the above arrangement, the power of the first servo motor 22 can be smoothly transmitted to the turntable 31, thereby driving the movement of the entire device. As a further implementation of this solution, the insert block 43 and the shaft hole 47 are connected to each other, and the shaft hole 47 is connected to the second ball groove 42. The outer side of the second bevel gear 54 is fixedly connected to the ball bearing 55. The transmission column 53 is rotatably connected to the inside of the shaft hole 47 through the ball bearing 55. The transmission column 53 extends out of the inside of the shaft hole 47. The second ball block 51 rotates inside the second ball groove 42. The tool body 56 is embedded in the inner side of the second tool fixing groove 52. Through the above settings, this design ensures the stability of the transmission column 53 during rotation and realizes the simultaneous angle adjustment of multiple PCD turning tools. This structural design significantly improves the efficiency and consistency of angle adjustment, and is particularly suitable for mass production operations, enhancing the practicality and convenience of the device. As a further implementation of this solution, a second servo motor 38 is fixedly connected to the inner side of the turntable 31, and a first bevel gear 39 is fixedly connected to the end of the spindle of the second servo motor 38. The shaft of the second servo motor 38, the shaft of the first bevel gear 39 and the shaft of the turntable 31 are vertically aligned. A first tool-fixing groove 35 is opened at the lower end of the first ball block 34, and a rotating ring 36 is fixedly connected to the outer side of the first ball block 34. The first ball block 34 and the turntable 31 are magnetically attracted. Through the above settings, the transmission error is reduced, the accuracy of angle adjustment is improved, and the magnetic adsorption effect prevents the first ball block 34 from loosening or falling off during the processing, thus providing convenience for the next processing step. As a further implementation of this solution, the guide rod 44 is slidably connected inside the guide hole 37, the upper end of the spring 45 is fixedly connected to the bottom end of the turntable 31, the size of the insert block 43 matches that of the receiving groove 32, and the insert block 43 is vertically aligned with the receiving groove 32. Through the above settings, it is ensured that the clamping block 41 can be guided smoothly and accurately during movement, while ensuring that the insert block 43 can be accurately inserted into the receiving groove 32, thereby achieving stable clamping of the PCD cutting tool and improving the stability and machining accuracy of the device.

[0021] Workflow: When fixing the tool body 56, multiple tool bodies 56 are placed inside the second tool fixing slot 52. After placement, the first servo motor 22 is started to drive the drive column 23 to rotate. The drive column 23 drives the turntable 31 to rotate. The turntable 31 drives the fixing component 4 and the rotating component 5 to rotate as a whole. Through the elastic force of the spring 45, the clamping block 41 is moved away from the turntable 31. This not only provides operating space for placing the tool body 56, but also ensures that the bottom end of the clamping block 41 is in close contact with the top end of the ramp 13. Since both the clamping block 41 and the ramp 13 are inclined structures, the clamping block 41 will gradually move upward when it rotates. The clamping block 41 drives the guide rod 44 to move upward. Sliding inside the guide hole 37, it guides the movement of the clamping block 41. At the same time, the clamping block 41 cooperates with the turntable 31 to compress the spring 45. The movement of the clamping block 41 drives the insert block 43 and the stop block 46 to move upward. At this time, the insert block 43 is inserted into the storage groove 32, and the top of the stop block 46 is in close contact with the bottom of the turntable 31. The first knife-fixing groove 35 opened by the first ball block 34 and the second knife-fixing groove 52 opened by the second ball block 51 are used to clamp the knife body 56, thereby achieving the function of fixing multiple knife bodies 56 at the same time. This fixing method eliminates the traditional method of fixing one by one with bolts, significantly reducing the difficulty of operation and the error rate, and reducing the probability of errors. When adjusting the angle of the tool body 56 during machining, the same principle applies as described above. When the clamping block 41 drives the rotating component 5 to move upward, the second bevel gear 54 meshes with the first bevel gear 39, activating the second servo motor 38 to drive the first bevel gear 39 to rotate. The first bevel gear 39 then drives multiple second bevel gears 54 to rotate simultaneously. The second bevel gears 54 in turn drive the transmission column 53 to rotate. Since the transmission column 53 is embedded inside the shaft hole 47, it rotates inside the shaft hole 47 via ball bearings 55. At the same time, the transmission column 53 drives the second ball block 51 and the tool body 56 to rotate. Through the compression of the first ball block 34 by the second ball block 51, the first ball block 34 rotates inside the first ball groove 33 via the rotating ring 36. This allows for stable control of the tool body 56 to adjust its angle. Simultaneously, the milling device 12 processes the tool body 56. This angle adjustment method is convenient and stable, and it is suitable for large-scale tool body 56 machining operations, improving ease of use. When the tool body 56 is removed, after processing, the rotation angle of the second bevel gear 54 is controlled by the second servo motor 38 so that the upper end of the second ball block 51 is flush with the upper end of the stop block 46, and the bottom end of the first tool fixing groove 35 is flush with the bottom end of the turntable 31. The first servo motor 22 is started in the opposite direction. Based on the same principle, the fixing component 4 and the rotating component 5 rotate as a whole. When the clamping block 41 moves, the clamping block 41 will move downward by the elastic force of the spring 45. This will make the second ball block 51 move away from the first tool fixing groove 35. Since the first tool fixing groove 35 is magnetically attracted to the turntable 31, this will prevent the first tool fixing groove 35 from detaching from the first ball groove 33. At this time, the tool body 56 can be removed directly, eliminating the need for the traditional method of disassembling one by one.

[0022] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
