Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a gear processing machine tool cutting tool. Background Technology

[0002] Gear processing machine tools are mechanical equipment specifically designed for processing gears. They occupy an important position in the machinery manufacturing industry. As key components for transmitting motion and power, gears are widely used in many fields such as automobiles, aerospace, and engineering machinery. Gear processing machine tools can process metal blanks into gears that meet design requirements through specific processing techniques.

[0003] In gear machining, cutting tools are an indispensable and important component. They directly participate in the cutting process, removing excess material through relative movement with the gear blank, thereby forming the tooth profile, tooth grooves, and other structures of the gear. The performance and quality of the cutting tools directly affect the machining accuracy, surface quality, and machining efficiency of the gear.

[0004] A certain gear machining tool has the following shortcomings:

[0005] The existing cutting tools have fixed cutter head lengths, requiring the replacement of different specifications of cutting tools when machining gears of different sizes. This operation is cumbersome and costly, and the lack of an effective synchronization adjustment mechanism makes it difficult to ensure that multiple cutting heads work together, resulting in a decrease in machining accuracy. In addition, the heat dissipation of existing cutting tools relies on natural air cooling. During high-speed cutting, heat cannot be dissipated in time, and the cutting tools wear rapidly due to high temperatures. This not only shortens the tool life but also increases the dimensional deviation of the machined gears, seriously affecting product quality. Utility Model Content

[0006] This utility model proposes a gear processing machine tool with adjustable tool head length, multi-tool head synchronous adjustment and efficient heat dissipation function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a gear processing machine tool cutting tool, including a rotating disk, wherein a plurality of telescopic cutting heads are fixedly connected in a ring array on the outer surface of the rotating disk, and a telescopic linkage frame is provided on the opposite face of two adjacent telescopic cutting heads, and a positioning component is fixedly connected to the upper and lower sides of two telescopic linkage frames arranged symmetrically in front and behind.

[0008] The telescopic cutter head includes a connecting plate, which is fixedly connected to the outer surface of the rotating disk. A sliding cutter head is slidably sleeved on the outer surface of the connecting plate away from the rotating disk. Connecting grooves are provided on both the front and rear sides of the upper and lower surfaces of the rotating disk. A positioning through hole is provided on the opposite side of the two connecting grooves. The telescopic linkage frame includes a square sleeve. Telescopic sliding plates are slidably inserted into the left and right sides of the inner surface of the square sleeve. The end of the telescopic sliding plate away from the square sleeve is fixedly connected to the outer surface of the sliding cutter head.

[0009] Preferably, the positioning component includes two connecting slide plates, which are respectively fixedly connected to the upper and lower sides of the square sleeve, and the outer surface of the connecting slide plate away from the square sleeve is slidably connected to the inner surface of the connecting groove.

[0010] Preferably, the inside of the connecting slide plate has several vertically penetrating positioning holes on the side near the connecting groove, and a vertically penetrating double-headed bolt is slidably inserted into the inner surface of two of the positioning holes.

[0011] Preferably, the outer surface of the double-ended bolt is slidably inserted into the inner surface of the positioning through hole, and nuts are threaded on both the upper and lower sides of the outer surface of the double-ended bolt.

[0012] Preferably, the rotating disk has a plurality of vertically extending oblique air guide slots arranged in an internal annular array. A cylindrical slot is formed in the middle of the oblique air guide slots, and a connecting slot is formed on the inner wall of the cylindrical slot near the connecting plate. The connecting slot extends into the interior of the connecting plate.

[0013] Preferably, a plurality of heat dissipation fins are fixedly connected to the inner surface of the sliding cutter head away from the connecting plate, and dustproof mesh is provided on both the front and rear sides of the outer surface of the sliding cutter head, the dustproof mesh extending through the inner surface of the sliding cutter head.

[0014] Preferably, the connecting plate has a T-shaped flow groove inside, and the front and rear ends of the T-shaped flow groove extend to the front and rear sides of the outer surface of the connecting plate, respectively.

[0015] Preferably, dustproof netting is fixedly connected to the inner surfaces of both ends of the T-shaped flow channel.

[0016] Preferably, one end of the T-shaped flow groove extends through to the side of the connecting plate away from the rotating disk, and a guide fan is rotatably connected to its inner surface. A connecting shaft is fixedly connected to the side of the guide fan near the rotating disk.

[0017] Preferably, the end of the connecting shaft near the rotating disk passes through the communicating groove, and the end of the connecting shaft near the rotating disk extends into the interior of the cylindrical groove and is fixedly connected to a transmission fan.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. In this utility model, the length of the sliding cutter head can be adjusted by sliding the sliding cutter head on the outer surface of the connecting plate. The telescopic sliding plate of the telescopic linkage frame is connected to the sliding cutter head. When one of the sliding cutter heads is adjusted, the telescopic linkage frame can drive all the telescopic cutter heads to extend and retract synchronously, ensuring that multiple cutter heads work together. At the same time, the connecting sliding plate slides in the connecting groove. The double-ended bolt passes through the positioning hole and the positioning through hole, and is then fixed with a nut. This can accurately fix the position of the connecting sliding plate, thereby locking the length of the cutter head after adjustment. This structural design greatly improves the adaptability of the tool to gears of different specifications, reduces the frequency of tool changes, reduces processing costs, and improves processing efficiency and accuracy.

[0020] 2. In this utility model, when the tool rotates, air passes through the inclined guide groove, blowing the drive fan to rotate. The drive fan drives the guide fan to rotate in the T-shaped flow groove through the connecting shaft, causing air to enter the inner side of the sliding cutter head from the T-shaped flow groove and be discharged through the dustproof net. During this process, the heat dissipation fins in the sliding cutter head increase the heat exchange area, and the air flow carries away a large amount of heat generated by cutting, forming an efficient self-driven heat dissipation cycle. This heat dissipation structure effectively avoids tool wear and deformation due to high temperature, ensures gear machining accuracy, and significantly extends the tool's service life.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: As Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, this utility model provides a technical solution: it includes a rotating disk 1, with a plurality of telescopic cutter heads 2 fixedly connected in a ring array on the outer surface of the rotating disk 1. A telescopic linkage frame 3 is provided on the opposite face of two adjacent telescopic cutter heads 2. A positioning component 4 is fixedly connected to the upper and lower sides of two symmetrically arranged telescopic linkage frames 3. The telescopic cutter head 2 includes a connecting plate 21, which is fixedly connected to the outer surface of the rotating disk 1. A sliding cutter head 22 is slidably sleeved on the side of the outer surface of the connecting plate 21 away from the rotating disk 1. Connecting grooves 11 are provided on the front and rear sides of the upper and lower surfaces of the rotating disk 1. A positioning through hole 12 is provided on the opposite face of the two upper and lower connecting grooves 11. The telescopic linkage frame 3 includes a square sleeve 31, with the inner surface of the square sleeve 31 having left and right sides... Telescopic slide plates 32 are slidably inserted on both sides. The end of the telescopic slide plate 32 away from the square sleeve 31 is fixedly connected to the outer surface of the sliding cutter head 22. The positioning component 4 includes two connecting slide plates 41. The two connecting slide plates 41 are fixedly connected to the upper and lower sides of the square sleeve 31 respectively. The outer surface of the connecting slide plate 41 away from the square sleeve 31 is slidably connected to the inner surface of the connecting groove 11. Several vertically penetrating positioning holes 42 are opened on the side of the connecting slide plate 41 near the connecting groove 11. A vertically penetrating double-headed bolt 43 is slidably inserted into the inner surface of the two positioning holes 42. The middle part of the outer surface of the double-headed bolt 43 is slidably inserted into the inner surface of the positioning through hole 12. Nuts 44 are threadedly connected to both the upper and lower sides of the outer surface of the double-headed bolt 43.

[0030] The effect achieved by the entire embodiment 1 is as follows: When it is necessary to process gears of different specifications, any sliding cutter head 22 can be manually pushed to slide on the outer surface of the connecting plate 21. Since the telescopic slide plate 32 is connected to the sliding cutter head 22, the telescopic slide plate 32 in the square sleeve 31 will drive the adjacent sliding cutter head 22 to move synchronously, realizing the synchronous telescopic adjustment of all telescopic cutter heads 2. After adjusting to the appropriate length, the double-ended bolt 43 is passed through the positioning hole 42 on the connecting slide plate 41 and the positioning through hole 12 on the rotating disk 1, and then the nut 44 is tightened to fix the connecting slide plate 41 in the connecting slide groove 11, thereby accurately locking the length of the cutter head after adjustment, so that the cutter can adapt to the processing requirements of different gears, without the need to frequently change the cutter, effectively reducing processing costs and improving processing efficiency and accuracy.

[0031] Example 2: As Figure 2 and Figure 5As shown, this utility model provides a technical solution: The rotating disk 1 has a plurality of vertically penetrating oblique air guide grooves 13 arranged in a circular array inside. A cylindrical groove 14 is formed in the middle of each oblique air guide groove 13. A connecting groove 15 is formed on the inner wall of the cylindrical groove 14 near the connecting plate 21, extending into the interior of the connecting plate 21. A plurality of heat dissipation fins 24 are fixedly connected to the inner surface of the sliding cutter head 22 away from the connecting plate 21. Dustproof nets 23 are formed on both the front and rear sides of the outer surface of the sliding cutter head 22, extending into the inner surface of the sliding cutter head 22. The connecting plate 21... The part is provided with a T-shaped flow groove 25. The front and rear ends of the T-shaped flow groove 25 extend to the front and rear sides of the outer surface of the connecting plate 21, respectively. Dustproof nets 26 are fixedly connected to the inner surfaces of the front and rear ends of the T-shaped flow groove 25. One end of the T-shaped flow groove 25 extends to the side of the connecting plate 21 away from the rotating disk 1 and is rotatably connected to the inner surface of the connecting plate 21. A connecting shaft 28 is fixedly connected to the side of the connecting shaft 27 near the rotating disk 1. The end of the connecting shaft 28 near the rotating disk 1 extends through the connecting groove 15. The end of the connecting shaft 28 near the rotating disk 1 extends into the interior of the cylindrical groove 14 and is fixedly connected to the drive fan 29.

[0032] The effect achieved by the entire embodiment 2 is as follows: During the operation of the tool rotation, outside air passes through the inclined air guide groove 13 on the rotating disk 1. The flowing air drives the transmission fan 29 in the cylindrical groove 14 to rotate. The transmission fan 29 drives the guide fan 27 in the T-shaped flow groove 25 to rotate synchronously through the connecting shaft 28. The rotation of the guide fan 27 causes air to enter from one end of the T-shaped flow groove 25, pass through the connecting plate 21 and enter the inner side of the sliding head 22. During the flow, the air fully contacts the heat dissipation fins 24, carrying away a large amount of heat generated by the cutting of the sliding head 22. Finally, it is discharged through the dustproof net 23 on the sliding head 22. The dustproof net 23 and the dustproof net 26 can effectively prevent iron filings, dust and other debris from entering the flow channel during the cutting process, ensuring the normal operation of the heat dissipation system, forming an efficient self-driven heat dissipation cycle, effectively avoiding tool wear and deformation due to high temperature, ensuring gear machining accuracy, and extending tool service life.

[0033] The working principle of the entire equipment is as follows: When using the gear processing machine tool, firstly, according to the specifications of the gear to be processed, the sliding cutter head 22 is manually pushed, and the telescopic linkage frame 3 is used to realize the synchronous telescopic adjustment of all telescopic cutter heads 2. After the cutter head is adjusted to a suitable length, the connecting slide plate 41 is fixed in the connecting slide groove 11 by the double-headed bolt 43 and nut 44 of the positioning component 4, thus completing the preparation of the tool.

[0034] Subsequently, the cutting tool is installed on the gear processing machine tool, and the machine tool is started to make the rotating disk 1 rotate at high speed. During the rotation of the rotating disk 1, the inclined air guide groove 13 guides the flow of outside air, and the air drives the transmission fan 29 to rotate, which in turn drives the guide fan 27 to rotate, so that the air forms a heat dissipation airflow channel inside the T-shaped flow groove 25, the connecting plate 21 and the sliding cutter head 22.

[0035] When the cutting tool cuts the gear blank, the telescopic cutting head 2 contacts the gear blank and removes excess material to form the tooth shape and tooth groove of the gear. During this process, the heat generated by the sliding cutting head 22 is absorbed by the heat dissipation fins 24, and the rotating guide fan 27 accelerates the air flow, carries away the heat and exhausts it to the outside of the cutting tool, ensuring that the cutting tool works at a suitable temperature.

[0036] When machining a gear of one specification is completed and other specifications need to be machined, simply loosen the nut 44, pull out the double-ended bolt 43, readjust the position of the sliding cutter head 22, and repeat the above fixing steps to quickly adapt to the new machining requirements and achieve efficient and precise gear machining.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
