Description

Technical Field

[0001] The present invention relates to the technical field of gear hobbing equipment, and particularly relates to a PCD tool for gear hobbing. Background Art

[0002] PCD tools refer to polycrystalline diamond tools, which are mainly used for machining materials with higher hardness, such as aluminum alloys, copper alloys, plastics, and composite materials. Due to the excellent wear resistance and thermal conductivity of PCD tools, they can provide longer service life and higher machining accuracy, and are widely used in fields such as machining and die manufacturing. They are usually used in processes such as cutting, milling, and drilling, and are suitable for high-efficiency and high-precision machining requirements.

[0003] For example, a Chinese invention patent (CN108907367B) discloses a gear machining tool, which records: "When it is necessary to disassemble the machining tool, move the two push rods towards the side close to each other, so that the bottoms of the two U-shaped rods are respectively disengaged from the two second positioning grooves, which can facilitate the disassembly and replacement of the machining tool", and also records: "After the device is adjusted, it needs to be fastened by bolts, which makes the adjustment work complicated, reduces the work efficiency, and at the same time, this device cannot conveniently adjust the position of the machining tool according to gears of different sizes, and the machining tool is not easy to disassemble and maintain, making it inconvenient to use and there is room for improvement" technical problems.

[0004] In summary, it can be seen that in the prior art, the two push rods are moved towards the side close to each other, so that the bottoms of the two U-shaped rods are respectively disengaged from the two second positioning grooves. However, this method has the following technical problems: but by inserting the bottoms of the two U-shaped rods into the corresponding two second positioning grooves, during the cutting process, the contact area, angle, and pressure between the tool and the gear teeth change, resulting in a change in the cutting force generated by the interaction between the tool and the workpiece, and further causing the tool to vibrate to a certain extent. Just using a spring to push the U-shaped rod against the second positioning groove cannot achieve stable fixation of the tool, thereby affecting the machining quality of the gear teeth. Therefore, this application proposes a PCD tool for gear hobbing, and provides a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Invention

[0005] Based on this, it is necessary to provide a PCD tool for gear hobbing to address the above technical problems. After inserting the mounting shell into the support shell, the limiting tooth plate is pushed to drive the frustum to move towards the side close to the rotating rod, and then the four limiting rods on the up, down, left, and right sides are driven to pass through the mounting shell and be stuck in the support shell. During this process, the limiting claws always tend to closely adhere to the top of the limiting tooth plate under the elastic force of the torsion spring. And after pushing the limiting tooth plate to the appropriate position, the limiting claws limit the sliding of the limiting tooth plate inside the support shell by pressing against the corresponding teeth on the limiting tooth plate at this time, so that the limiting tooth plate cannot slide in the direction away from the rotating rod, ensuring that the four limiting rods on the up, down, left, and right sides are stably stuck in the support shell.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The PCD tool for gear cutting provided by the present invention inserts the mounting shell into the supporting shell, pushes the limiting tooth plate to drive the four-sided pyramid to move to the side close to the rotating rod, and then drives the four limiting rods of the upper, lower, left and right to pass through the mounting shell and be stuck in the supporting shell. During this process, the limiting claw always keeps a tendency to be tightly attached to the top of the limiting tooth plate under the elastic force of the torsion spring, and after the limiting tooth plate is pushed to a suitable position, the limiting claw presses against the corresponding teeth on the limiting tooth plate at this time to limit the sliding of the limiting tooth plate inside the supporting shell, so that the limiting tooth plate cannot slide in the direction away from the rotating rod, so as to ensure that the four limiting rods of the upper, lower, left and right are stably stuck in the supporting shell, and the mounting shell is fixed in multiple directions to ensure the firmness of the mounting shell.

[0020] The PCD tool for gear cutting provided by the present invention limits the sliding of the limiting tooth plate inside the supporting shell by the hard abutment between the limiting claws and the teeth on the limiting tooth plate, and the hard abutment between the non-rotating roller and the quadrangular platform enables the limiting rod to be stably inserted into the fixed plate, and the hard abutment between the limiting rod and the limiting shell, the mounting shell and the supporting shell respectively makes the movable distance of the mounting shell relative to the supporting shell or the limiting shell after installation extremely small, and the convenient hard abutment enables the tool body to better transmit the cutting force during gear cutting, reduces the displacement and vibration of the tool body, avoids the situation where the spring will produce elastic deformation when under pressure, resulting in increased vibration risk, improves the stability of the tool body installation, and the limiting claw can be separated from the limiting tooth plate by rotating the adjusting rod, and the limiting tooth plate can be pulled out to a suitable position to separate the limiting rod from the mounting shell, and the mounting shell, the rotating rod and the tool body can be disassembled immediately, and the process is relatively simple and convenient, which improves the practicality of the device.

[0021] The PCD tool for gear cutting provided by the present invention can guide and diffuse the heat generated by the processing of the tool body through the contact between the heat sink and the mounting shell, thereby reducing the heat accumulation in the tool body. In the process of controlling the driving motor to drive the tool body to rotate, the driving motor can drive the rotating shaft to rotate the active gear, thereby causing the multiple fan blades to rotate, thereby driving the air flow, so that the air enters the device housing through the protective net, and then takes away the heat generated by the processing of the tool body through the heat sink and the mounting shell and the rotating rod, and then blows to the outside through the first blocking mesh plate and the second blocking mesh plate. This part of the air can further take away the gas around the tool body that has exchanged heat with the tool body, thereby improving the heat dissipation effect of the tool body, and the wind can also take away the debris generated by the processing to reduce the wear of the tool body caused by the debris, thereby improving the service life of the tool body, and the heat dissipation of the tool body can reduce the risk of deformation and damage of the tool body due to overheating caused by friction between the tool body and the workpiece during operation, thereby improving the service life of the tool body.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As described in the background art, however, by inserting the bottom ends of the two U-shaped rods into the corresponding two second positioning grooves, during the cutting process, the contact area, angle, and pressure between the tool and the gear hobbing change, causing the cutting force generated by the interaction between the tool and the workpiece to change accordingly, and further causing the tool to vibrate to a certain extent. Just using the spring to push the U-shaped rod against the second positioning groove cannot achieve stable fixation of the tool, thus affecting the machining quality of the gear hobbing.

[0036] To solve this technical problem, the present invention provides a PCD tool for gear hobbing, which is applied to gear hobbing machining.

[0037] Specifically, please refer to Figures 1 - 2 , the PCD tool for gear hobbing specifically includes:

[0038] The device housing 1 is provided with a mounting mechanism 2 and an auxiliary mechanism 3. A driving motor 4 is fixedly installed on the outer wall of the device housing 1, and a rotating shaft 5 is rotatably connected to the inner wall of the device housing 1. One end of the rotating shaft 5 is fixedly connected to the output end of the driving motor 4;

[0039] The mounting mechanism 2 includes a connecting frame 6, a support shell 7, a pulling component, a mounting component, a first limiting component, a second limiting component, and a protection component. One end of the rotating shaft 5 away from the driving motor 4 is fixedly connected to the connecting frame 6, and a support shell 7 is fixedly connected to one side of the connecting frame 6 away from the rotating shaft 5.

[0040] In the PCD tool for gear hobbing provided by the present invention, after inserting the mounting shell 8 into the support shell 7, the limiting tooth plate 12 is pushed to drive the frustum 13 to move towards the side close to the rotating rod 9, and then the four limiting rods 15 in the up, down, left, and right directions are driven to pass through the mounting shell 8 and be stuck in the support shell 7. During this process, the limiting claw 20 always tends to keep close to the top of the limiting tooth plate 12 under the elastic force of the torsion spring 21, and after pushing the limiting tooth plate 12 to a proper position, the limiting claw 20 restricts the sliding of the limiting tooth plate 12 inside the support shell 7 by abutting against the corresponding teeth on the limiting tooth plate 12 at this time, so that the limiting tooth plate 12 cannot slide away from the rotating rod 9, ensuring that the four limiting rods 15 in the up, down, left, and right directions are stably stuck in the support shell 7. By fixing the mounting shell 8 in multiple directions, the firmness of the installation of the mounting shell 8 is ensured.

[0041] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0042] Embodiment 1:

[0043] Please refer to Figures 2 - 9 , a PCD tool for gear hobbing, which includes:

[0044] The pulling component includes a limiting shell 11. The limiting shell 11 is fixedly connected to the inner wall of the support shell 7. A limiting tooth plate 12 is slidably connected to the inner wall of the support shell 7. One end of the limiting tooth plate 12 located inside the support shell 7 is fixedly connected to a frustum 13. Baffles 14 are respectively fixedly connected to the front and rear sides of the frustum 13. The baffles 14 can prevent the rollers 16 from leaving the frustum 13 when sliding on the frustum 13.

[0045] The mounting component includes a mounting shell 8. The mounting shell 8 is inserted between the support shell 7 and the limiting shell 11. A rotating rod 9 is fixedly connected to one side of the mounting shell 8 away from the connecting frame 6. A tool body 10 is fixedly connected to one end of the rotating rod 9 away from the mounting shell 8.

[0046] The first limiting component includes a limiting rod 15. The upper, lower, left, and right inner walls of the limiting shell 11 are respectively slidably connected to the limiting rod 15. The four limiting rods 15 all pass through the mounting shell 8 and are inserted into the support shell 7. The inner walls of the four limiting rods 15 are all rotatably connected with rollers 16. The four rollers 16 are respectively in rolling connection with the upper, lower, left, and right sides of the frustum 13. The outer wall of the limiting rod 15 is fixedly connected with a fixing plate 17. A first spring 18 is sleeved on the outside of the limiting rod 15. The two ends of the first spring 18 are respectively fixedly connected to the inner wall of the limiting shell 11 and the outer wall of the fixing plate 17. The first spring 18 can enable the limiting tooth plate 12 to be pulled away from the rotating rod 9 when the mounting shell 8 is disassembled, so that the roller 16 can be kept tightly attached to the outer wall of the frustum 13 under the action of the elastic force of the first spring 18.

[0047] The second limiting component includes an adjusting rod 19. The outer wall of the support shell 7 is rotatably connected to the adjusting rod 19. A limiting claw 20 is fixedly connected to the outer wall of the adjusting rod 19 near the middle position. Torsion springs 21 are respectively sleeved on the outer wall of the adjusting rod 19 on both sides of the limiting claw 20. The two ends of the two torsion springs 21 are respectively fixedly connected to the outer walls of the support shell 7 and the limiting claw 20. The limiting claw 20 can limit the position of the limiting tooth plate 12. When the limiting claw 20 is attached to the teeth of the limiting tooth plate 12, the limiting tooth plate 12 cannot be pulled outwards. The teeth on the limiting tooth plate 12 are similar to triangular prisms.

[0048] The protection component includes a first blocking net plate 22. The first blocking net plate 22 is fixedly connected to the inner wall of the device housing 1. A rotating door 23 is rotatably connected to the outer wall of the device housing 1. A second blocking net plate 24 is fixedly connected to the outer wall of the rotating door 23. A plurality of balls 25 are in rolling connection with the inner walls of the first blocking net plate 22 and the second blocking net plate 24. The balls 25 are in contact with the outer wall of the rotating rod 9, making the rotation of the rotating rod 9 relative to the first blocking net plate 22 and the second blocking net plate 24 smoother. Columns 27 are respectively slidably connected to the upper and lower sides of the middle part of the inner wall of the rotating door 23. Sliding plates 26 are respectively fixedly connected to the outer walls of the two columns 27. The sliding plates 26 are slidably connected to the inner wall of the rotating door 23. Second springs 28 are respectively fixedly connected to the ends of the two columns 27 close to each other. The ends of the two second springs 28 close to each other are both fixedly connected to the inner wall of the rotating door 23. Two card holes 29 are opened in the inner wall of the device housing 1. The columns 27 are inserted into the card holes 29.

[0049] Through the above structural design, when the installation shell 8, the rotating rod 9 and the tool body 10 are installed, the two sliding plates 26 are squeezed toward the middle, driving the clamping column 27 to leave the corresponding clamping hole 29. In this process, the second spring 28 is deformed, and then the rotating door 23 can be pulled, so that the rotating door 23 carries the second blocking mesh plate 24 and the corresponding ball 25 to rotate relative to the device housing 1. Then, the two sliding plates 26 are loosened, and the clamping column 27 can slide a certain distance inside the rotating door 23 under the action of the elastic force of the second spring 28, and then the outer wall of the rotating rod 9 is in contact with the ball 25 on the first blocking mesh plate 22, and the installation shell 8 is located in the device housing 1, and then the mounting shell 8 is inserted into the supporting shell 7, pushing the limiting tooth plate 12 to drive the four-sided platform 13 to move to the side close to the rotating rod 9, thereby causing the four rollers 16 to roll on the upper, lower, left and right surfaces of the four-sided platform 13, and thereby causing the first spring 18 to deform, so that the four upper, lower, left and right limiting rods 15 pass through the mounting shell 8 and are finally stably stuck in the supporting shell 7. During this process, the limiting claw 20 always maintains a tendency to be closely attached to the top of the limiting tooth plate 12 under the elastic force of the torsion spring 21, and after the limiting tooth plate 12 is pushed to a suitable position, the limiting claw 20 presses against the corresponding teeth on the limiting tooth plate 12 at this time, thereby 12 is limited in sliding inside the support shell 7, so that the limiting tooth plate 12 cannot slide in the direction away from the rotating rod 9, and then the two sliding plates 26 can be squeezed toward the middle, driving the clamping column 27 to be retracted into the rotating door 23, and the second spring 28 is deformed accordingly, and then the rotating door 23 is rotated, so that the ball 25 in the second blocking mesh plate 24 contacts the rotating rod 9, and then the two sliding plates 26 are released, so that the two clamping columns 27 can be inserted into the corresponding clamping holes 29 under the action of the corresponding second spring 28 elastic force, and the rotating door 23 is closed, and then the installation shell 8, the rotating rod 9 and the tool body 10 are installed. When disassembling the tool body 10, the rotating door 23 is opened, and then the adjusting rod 19 is rotated to make the limiting claw 20 leave the limiting tooth plate 12. In this process, the torsion spring 21 is deformed, and then the limiting tooth plate 12 is pulled out, so that the limiting rod 15 makes the roller 16 close to the quadrangular platform 13 under the action of the elastic force of the corresponding first spring 18. As the limiting tooth plate 12 is pulled out, the limiting rod 15 can gradually leave the supporting shell 7 and then leave the mounting shell 8. Then the mounting shell 8 can be pulled out, and then the adjusting rod 19 is released, so that the limiting claw 20 can be attached to the limiting tooth plate 12 again under the action of the elastic force of the torsion spring 21, and then the rotating door 23 is closed to complete the disassembly of the tool body 10.

[0050] Embodiment 2:

[0051] The PCD tool for gear cutting provided in Example 1 is further optimized. Specifically, Figures 2 - 4As shown in the figure, the auxiliary mechanism 3 includes a heat sink 30. A plurality of heat sinks 30 are fixedly connected to the inner wall of the support shell 7. The heat sinks 30 are closely attached to the outer wall of the mounting shell 8. The heat generated by the operation of the tool body 10 can be transmitted to the inside of the mounting shell 8 through the rotating rod 9, and then the heat inside the mounting shell 8 is guided and transmitted to the air through the heat sinks 30.

[0052] The auxiliary mechanism 3 further includes a driving gear 31. The driving gear 31 is fixedly connected to the outer wall of the rotating shaft 5. A plurality of rotating columns 32 are rotatably connected to the inner wall of the device housing 1. Driven gears 33 are respectively fixedly connected to the outer walls of the plurality of rotating columns 32. The plurality of driven gears 33 are all engaged with the outer wall of the driving gear 31. Fan blades 34 are respectively fixedly connected to one ends of the plurality of rotating columns 32 close to the heat sink 30. A plurality of protective nets 35 are fixedly installed on the inner wall of the device housing 1. The protective nets 35 can reduce the entry of external dust into the device housing 1 and protect the internal structure of the device housing 1.

[0053] Through the above structural design, when the driving motor 4 is started to drive the rotating shaft 5 to rotate, and then the rotating shaft 5 drives the mounting shell 8, the rotating rod 9 and the tool body 10 to rotate through the connecting frame 6 and the support shell 7, and then the car teeth are processed. During this process, the rotation of the rotating shaft 5 can drive the driving gear 31 to rotate accordingly, and then drive the plurality of driven gears 33 to rotate through the rotation of the driving gear 31. Then, the fan blades 34 are driven to rotate through the corresponding rotating columns 32, thereby driving the air to flow, so that the external air enters the device housing 1 through the protective net 35. Then, the heat diffused from the heat sink 30 to the surrounding air is taken away, and then blown to the outside through the first baffle plate 22 and the second baffle plate 24. This part of the air can further take away the gas that has exchanged heat with the tool body 10 around the tool body 10, and the wind force can also take away the chips generated during processing.
