Description

Technical Field

[0001] This invention relates to the field of gear shaft processing equipment technology, and specifically to a pretreatment process for high-speed motor gear shaft materials. Background Technology

[0002] The machining process of gear shafts typically includes key steps such as preliminary forming, rough machining, heat treatment, finish machining, surface treatment, and inspection and testing. Among these, finish machining includes gear grinding, which plays a crucial role in gear machining. Gear grinding can significantly improve the gear's tooth profile accuracy, pitch accuracy, and direction accuracy. Furthermore, gear grinding can effectively improve the gear's surface quality by removing defects such as oxide scale and cracks generated after heat treatment, making the gear surface smoother and more uniform. This improvement in surface quality helps to enhance the gear's wear resistance and fatigue resistance, thereby extending the gear's service life.

[0003] In existing gear grinding processes, the high-speed friction between the cutting tool and the gear workpiece surface during grinding generates a large amount of cutting heat, most of which is transferred to the workpiece. Therefore, continuous flushing with cooling oil during grinding plays a crucial role in reducing temperature and removing impurities. However, the gear grinding process usually involves grinding each gear tooth individually. After the first tooth is ground, the gear needs to be rotated to move the second tooth to the grinding assembly for further processing. During this process, the freshly ground tooth moves away from the cooling oil flushing area, and the heat can only be dissipated naturally, which is relatively slow. This can easily lead to heat remaining on the tooth surface. Moreover, when adjacent tooth blocks are being ground, the resulting grinding debris will fly everywhere and easily fall onto surrounding tooth blocks. If it falls on the freshly ground tooth surface, it will not only affect the heat dissipation of that tooth but also affect the precision and quality of the tooth surface due to the adhesion of grinding debris, thereby affecting the overall performance and service life of the gear. Based on this, the present invention aims to provide a high-speed motor gear shaft material pretreatment process that can continuously and specifically cool the freshly ground teeth. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a pretreatment process for high-speed motor gear shaft materials, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A pretreatment process for high-speed motor gear shaft materials includes:

[0007] A base is provided, on which a bracket is fixedly installed, and a clamping assembly is provided on the base. The clamping assembly is connected to the bracket and is used to clamp and fix the gear shaft body. The clamping assembly drives the gear shaft body to rotate. The axis of the gear shaft body is arranged longitudinally. A grinding assembly is provided on the bracket and is used to grind the tooth surface of the gear shaft body. An oil spray nozzle is fixedly installed on the bracket and is connected to an external oil supply assembly. The oil spray nozzle sprays cooling oil onto the tooth surface of the gear shaft body that is being ground by the grinding assembly.

[0008] A circulating purification component is mounted on a base and located below the clamping component and the gear shaft body. The circulating purification component is used to process the cooling oil sprayed from the oil injection nozzle into circulating oil. A liquid storage tank is fixedly installed on the base and is connected to the circulating purification component. The liquid storage tank is used to store the circulating oil. A first V-shaped tube and a second V-shaped tube are fixedly installed on the bracket. The first V-shaped tube and the second V-shaped tube are symmetrically arranged and are both connected to the liquid storage tank. The first V-shaped tube and the second V-shaped tube respectively spray the circulating oil onto the left and right adjacent tooth surfaces of the gear shaft body that are being ground.

[0009] As a further embodiment of the present invention: the circulating purification component includes a funnel, a filter screen, a collection tank, a filter component, and a return pipe. The collection tank is located below the base, the funnel is disposed on the base and is located below the clamping component and the gear shaft body, the filter screen is disposed at the outlet of the funnel and the outlet of the funnel faces the collection tank, the input end of the filter component is connected to the collection tank, and the output end of the filter component is connected to the storage cylinder through the return pipe.

[0010] As a further aspect of the present invention, the filter screen and the funnel are detachably connected.

[0011] As a further embodiment of the present invention: the circulating purification component further includes a circular ring, a conical guide platform, and an annular baffle. The circular ring is disposed on the base and located above the funnel. The inner ring of the circular ring is fixedly connected to the conical guide platform by three circumferentially arranged connecting rods. The conical guide platform is located below the gear shaft body, and the axis of the conical guide platform coincides with that of the gear shaft body. The radius of the conical guide platform decreases upward along the axial direction. There is a channel between the edge of the conical guide platform and the inner ring of the circular ring. The annular baffle is sleeved on the edge of the conical guide platform, and the annular baffle and the bottom of the conical guide platform form a sedimentation tank.

[0012] As a further aspect of the present invention: the annular baffle and the conical guide platform are detachably connected. The bottom of the annular baffle has three circumferentially arranged grooves, which are slidably engaged with the connecting rod. A recycling box is slidably installed on the base. The recycling box is located between the annular ring and the funnel. When the annular baffle is installed on the conical guide platform, the recycling box is away from the space between the annular ring and the funnel. When the annular baffle is detached from the conical guide platform, the recycling box is located directly below the annular ring.

[0013] As a further aspect of the present invention: a water pipe is fixedly installed on the bracket, the outlet of the water pipe faces the conical guide platform, and the water pipe is connected to an external water supply component.

[0014] As a further aspect of the present invention: both the funnel and the ring are rotatably mounted on the base, the funnel is driven to rotate by a first drive source built into the base, and the ring is driven to rotate by a second drive source built into the base.

[0015] As a further embodiment of the present invention: the clamping assembly includes an upper circular block, a lower circular block, a support plate, and a telescopic component. The upper circular block is rotatably mounted on the bracket and is driven to rotate by a third drive source built into the bracket. The support plate is fixedly mounted on the base. The telescopic component is fixedly mounted on the support plate, and its movable end is rotatably mounted with the support plate. The telescopic component is arranged through the conical guide platform and is rotatably connected to the conical guide platform. The support plate is coaxially arranged with the upper circular block. The two ends of the gear shaft body abut against the upper circular block and the lower circular block, respectively, and the axes of the gear shaft body, the upper circular block, and the lower circular block coincide.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, each tooth surface is pre-cleaned by circulating oil sprayed from the first V-tube during the grinding operation. Then, when the grinding assembly grinds the tooth surface, the cooling oil sprayed from the oil nozzle cools and cleans the tooth surface during grinding. After grinding, the circulating oil sprayed from the second V-tube continuously cools the tooth surface of the gear shaft body. This ensures that each tooth surface of the gear shaft body is closely linked from the pre-cleaning before grinding, to the cooling and cleaning during grinding, and then to the continuous cooling after grinding. This comprehensively guarantees the grinding quality of the tooth surface. Moreover, the first and second V-tubes use circulating oil that has been purified by the cooling oil sprayed from the oil nozzle. The rational use of the circulating oil not only meets the process requirements but also achieves efficient resource utilization and effective cost control.

[0018] 2. In this invention, cooling oil sprayed from the nozzle is collected by a funnel. Since the cooling oil sprayed from the nozzle will be mixed with grinding debris after passing through the grinding area, a filter screen is set at the outlet of the funnel. The filter screen intercepts the grinding debris in the cooling oil, allowing clean cooling oil to pass through the filter screen and enter the collection tank. Subsequently, the filtration assembly performs secondary purification on the cooling oil to further remove impurities and form circulating oil. Then, the circulating oil is injected into the storage tank through the return pipe for subsequent recycling in the first V-tube and the second V-tube. The circulating oil sprayed from the first V-tube and the second V-tube will be remixed into the cooling oil and recycled and purified again. This makes reasonable use of cooling oil resources and avoids waste.

[0019] 3. In this invention, after the cooling oil washes the grinding component on the grinding area of ​​the gear shaft body, it carries the grinding debris down onto the conical guide platform and slides down the inclined surface of the conical guide platform into the sedimentation tank, gradually filling the sedimentation tank and causing the liquid level to rise. During this process, the grinding debris will settle to the bottom in the cooling oil. When the liquid level exceeds the height of the annular baffle, the cooling oil will pass over the annular baffle and fall through the channel, then fall into the funnel for circulation and purification. Over a long period of use, larger grinding debris will gradually settle and fill the sedimentation tank. This allows for the direct interception of larger grinding debris in the sedimentation tank, achieving a separation effect and preventing these larger grinding debris from falling directly into the funnel, which could easily clog the filter screen. This achieves the effect of step-by-step filtration and purification. Attached Figure Description

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Please see Figures 1-6 As shown, this invention is a pretreatment process for high-speed motor gear shaft materials, comprising:

[0030] A base 1 is provided, on which a bracket 8 is fixedly installed, and a clamping component 2 is provided on the base 1. The clamping component 2 is connected to the bracket 8 and is used to clamp and fix the gear shaft body 3. The clamping component 2 drives the gear shaft body 3 to rotate. The axis of the gear shaft body 3 is arranged longitudinally. A grinding component 4 is provided on the bracket 8. The grinding component 4 is used to grind the tooth surface of the gear shaft body 3. An oil spray nozzle 5 is fixedly installed on the bracket 8. The oil spray nozzle 5 is connected to an external oil supply component and sprays cooling oil onto the tooth surface of the gear shaft body 3 that is being ground by the grinding component 4.

[0031] A circulating purification component is disposed on the base 1 and located below the clamping component 2 and the gear shaft body 3. The circulating purification component is used to process the cooling oil sprayed from the oil injection port 5 into circulating oil. A liquid storage tank 14 is fixedly installed on the base 1 and is connected to the circulating purification component. The liquid storage tank 14 is used to store the circulating oil. A first V-shaped tube 6 and a second V-shaped tube 7 are fixedly installed on the bracket 8. The first V-shaped tube 6 and the second V-shaped tube 7 are symmetrically arranged and are both connected to the liquid storage tank 14. The first V-shaped tube 6 and the second V-shaped tube 7 respectively spray the circulating oil to the left and right adjacent tooth surfaces of the gear shaft body 3 that are being ground.

[0032] In one embodiment, it should be noted that the external oil supply component and the grinding component 4 described in this invention are both prior art. The grinding component 4 can be a worm gear grinding wheel. This invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of this invention.

[0033] The working principle of this invention is as follows: First, the gear shaft body 3 is clamped and fixed by the clamping assembly 2. Then, the grinding assembly 4 grinds the tooth surface of the gear shaft body 3. During the grinding process, the external oil supply assembly continuously sprays cooling oil through the oil spray nozzle 5 onto the ground tooth surface of the gear shaft body 3 to cool the ground area and wash away the grinding debris. Subsequently, the cooling oil mixed with the grinding debris falls into the circulation and purification assembly. The circulation and purification assembly then processes the cooling oil mixed with the grinding debris to form circulating oil. The circulating oil enters the storage tank 14 for storage. Then, the storage tank 14 pumps the circulating oil to the first V-tube 6 and the second V-tube 7. The first V-tube 6 and the second V-tube 7 respectively spray the circulating oil onto the ground tooth surface of the gear shaft body 3. At the two adjacent tooth surfaces on the left and right sides of the gear shaft body 3 being ground, one of these two adjacent tooth surfaces will definitely be the next tooth surface to be ground after the gear shaft body 3 rotates. Allowing the circulating oil to flush this tooth surface beforehand prevents grinding debris from adhering to it, ensuring its cleanliness. After the grinding assembly 4 finishes grinding one tooth surface on the gear shaft body 3, the clamping assembly 2 drives the gear shaft body 3 to rotate, allowing the next tooth surface to be ground. At this time, the newly ground tooth surface will rotate to another circulating oil outlet, where the circulating oil will continuously flush the newly ground tooth surface, continuously carrying away the heat generated during grinding and ensuring that no grinding debris adheres to the tooth surface, hindering heat release. Figure 2 As shown in the figure, the grinding component 4 is grinding the tooth surface of the gear shaft body 3, while the circulating oil sprayed from the first V-tube 6 ensures that the tooth surface to be ground is clean, and the circulating oil sprayed from the second V-tube 7 cools and cleans the tooth surface that has been ground. This ensures that each tooth surface undergoes a complete process chain of pre-cleaning, cooling during processing, and post-processing.

[0034] like Figures 1-6 As shown, in a preferred embodiment of the present invention, the circulating purification component includes a funnel 9, a filter screen 10, a collection tank 11, a filter assembly 12, and a return pipe 13. The collection tank 11 is located below the base 1. The funnel 9 is disposed on the base 1 and is located below the clamping assembly 2 and the gear shaft body 3. The filter screen 10 is disposed at the outlet of the funnel 9, and the outlet of the funnel 9 faces the collection tank 11. The input end of the filter assembly 12 is connected to the collection tank 11, and the output end of the filter assembly 12 is connected to the storage cylinder 14 through the return pipe 13.

[0035] In practical application, the cooling oil sprayed from the nozzle 5 is collected by the funnel 9. Since the cooling oil sprayed from the nozzle 5 will be mixed with grinding debris after passing through the grinding area, a filter screen 10 is set at the outlet of the funnel 9. The filter screen 10 intercepts the grinding debris in the cooling oil, so that the clean cooling oil passes through the filter screen 10 and enters the collection tank 11. The filter assembly 12 draws the cooling oil in the collection tank 11 and performs secondary purification on the cooling oil to further remove impurities, forming circulating oil. Then, the circulating oil is injected into the storage tank 14 through the return pipe 13 for subsequent recycling by the first V-tube 6 and the second V-tube 7. The circulating oil sprayed from the first V-tube 6 and the second V-tube 7 will be remixed into the cooling oil and recycled and purified again. This makes reasonable use of cooling oil resources and avoids waste.

[0036] like Figures 1-6 As shown, in a preferred embodiment of the present invention, the filter screen 10 and the funnel 9 are detachably connected.

[0037] In practical applications, this embodiment takes into account that the abrasive particles will accumulate on the filter screen 10, thus affecting the filtration effect and the oil discharge efficiency of the funnel 9. Therefore, the filter screen 10 and the funnel 9 are designed to be detachably connected, which facilitates the cleaning and replacement of the filter screen 10 after long-term use.

[0038] like Figure 1-Figure 5 As shown, in a preferred embodiment of the present invention, the circulating purification component further includes a circular ring 15, a conical guide platform 16, and an annular baffle 17. The circular ring 15 is disposed on the base 1 and is located above the funnel 9. The inner ring of the circular ring 15 is fixedly connected to the conical guide platform 16 by three circumferentially arranged connecting rods 22. The conical guide platform 16 is located below the gear shaft body 3, and the axis of the conical guide platform 16 coincides with that of the gear shaft body 3. The radius of the conical guide platform 16 decreases upward along the axial direction. There is a channel 19 between the edge of the conical guide platform 16 and the inner ring of the circular ring 15. The annular baffle 17 is sleeved on the edge of the conical guide platform 16, and the annular baffle 17 and the bottom of the conical guide platform 16 form a sedimentation tank 18.

[0039] In practical application, when the cooling oil washes the grinding component 4 at the grinding area of ​​the gear shaft body 3, it carries the grinding debris down onto the conical guide platform 16 and slides down the inclined surface of the conical guide platform 16 into the sedimentation tank 18, gradually filling the sedimentation tank 18 and causing the liquid level to rise. During this process, the grinding debris will settle to the bottom in the cooling oil. When the liquid level exceeds the height of the annular baffle 17, the cooling oil will pass over the annular baffle 17 and fall through the channel 19, then fall into the funnel 9 for circulation and purification. Over long-term use, larger grinding debris will gradually settle and fill the sedimentation tank 18. This allows for the direct interception of larger grinding debris in the sedimentation tank 18, achieving a separation effect and preventing the larger grinding debris from falling directly into the funnel 9, which could easily clog the filter screen 10. This achieves the effect of step-by-step filtration and purification.

[0040] like Figure 1-Figure 5 As shown, in a preferred embodiment of the present invention, the annular baffle 17 and the conical guide platform 16 are detachably connected. The bottom of the annular baffle 17 is provided with three circumferentially arranged grooves 23, which are slidably engaged with the connecting rod 22. A recycling box 20 is slidably installed on the base 1. The recycling box 20 is located between the ring 15 and the funnel 9. When the annular baffle 17 is installed on the conical guide platform 16, the recycling box 20 is away from the space between the ring 15 and the funnel 9. When the annular baffle 17 is removed from the conical guide platform 16, the recycling box 20 is located directly below the ring 15.

[0041] In practical applications, this embodiment takes into account that after long-term use, the sedimentation tank 18 will be filled with grinding debris, thus affecting the separation effect of grinding debris. Therefore, the annular baffle 17 and the conical guide platform 16 are designed to be detachable. Figure 5 Taking the example shown, the annular baffle 17 and the conical guide platform 16 are separated. At this time, the sedimentation tank 18 is connected to the channel 19, and the recovery box 20 is moved between the ring 15 and the funnel 9. At this time, the grinding debris accumulated in the sedimentation tank 18 can be manually pushed into the recovery box 20 to achieve the purpose of cleaning. Then, the groove 23 on the annular baffle 17 is inserted along the connecting rod 22 to complete the installation of the annular baffle 17. This ensures that larger grinding debris can be continuously separated from the cooling oil, relieving the pressure on the subsequent filter screen 10 and filter assembly 12 for cooling oil filtration and purification.

[0042] like Figures 1-6 As shown, in a preferred embodiment of the present invention, a water pipe 21 is fixedly installed on the bracket 8, the outlet of the water pipe 21 faces the conical guide platform 16, and the water pipe 21 is connected to the external water supply component.

[0043] In one embodiment of this invention, it should be noted that the external water supply components described in this invention are prior art, and this invention does not improve upon them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of this invention.

[0044] In practical application, when cleaning the grinding debris accumulated in the sedimentation tank 18, water can be sprayed onto the conical guide platform 16 through the water pipe 21, so that the water flow can directly flush the grinding debris into the recycling box 20 without manual operation, and the cleaning effect can be improved by flushing through the water channel.

[0045] like Figures 1-6 As shown, in a preferred embodiment of the present invention, both the funnel 9 and the ring 15 are rotatably mounted on the base 1. The funnel 9 is driven to rotate by a first drive source built into the base 1, and the ring 15 is driven to rotate by a second drive source built into the base 1.

[0046] In one embodiment, both the first driving source and the second driving source can be selected from components such as a motor-driven pulley assembly or a motor-driven gear transmission assembly, or other mechanisms capable of achieving rotational motion. This embodiment does not impose specific limitations on these components.

[0047] In practical application, the spray points of the cooling oil and circulating oil are fixed, resulting in a fixed landing point on the conical guide platform 16. This causes a certain area in the sedimentation tank 18 to preferentially accumulate wear debris, making it easier for cooling oil carrying a large amount of wear debris to overflow from that area. This cooling oil then falls into the funnel 9 and down into the filter screen 10, inevitably causing a certain area in the filter screen 10 to accumulate wear debris first, leading to low utilization of the entire filter screen 10. Therefore, the first and second drive sources drive the funnel 9 and the ring 15 to rotate, thereby changing the landing points of the circulating oil and cooling oil on the conical guide platform 16. This allows the sedimentation tank 18 to uniformly intercept wear debris and allows the entire filter screen 10 to preferentially accumulate wear debris for a period of time, thereby improving the utilization of the entire filter screen 10.

[0048] like Figures 1-6As shown, in a preferred embodiment of the present invention, the clamping assembly 2 includes an upper circular block 201, a lower circular block 202, a support plate 203, and a telescopic member 204. The upper circular block 201 is rotatably mounted on the bracket 8 and is driven to rotate by a third drive source built into the bracket 8. The support plate 203 is fixedly mounted on the base 1. The telescopic member 204 is fixedly mounted on the support plate 203, and its movable end is rotatably mounted with the support plate 203. The telescopic member 204 is arranged through the conical guide platform 16 and is rotatably connected to the conical guide platform 16. The support plate 203 is coaxially arranged with the upper circular block 201. The two ends of the gear shaft body 3 abut against the upper circular block 201 and the lower circular block 202 respectively, and the axes of the gear shaft body 3, the upper circular block 201, and the lower circular block 202 coincide.

[0049] In one embodiment, the telescopic member 204 can be an electric cylinder, an electric telescopic rod, or other mechanisms that can realize the lifting and lowering movement of the lower circular block 202. The third drive source can be a servo motor, a servo motor, or other mechanisms that can realize rotational movement. This embodiment does not impose specific limitations on these components.

[0050] In practical application, the telescopic component 204 first lowers the lower circular block 202 to its lowest point. Then, the gear shaft body 3 is placed on the lower circular block 202, ensuring that the gear shaft body 3 is coaxial with the lower circular block 202. At this time, the gear shaft body 3 is also coaxial with the upper circular block 201. Subsequently, the telescopic component 204 drives the lower circular block 202 to rise, thereby moving the gear shaft body 3 upward to abut against the upper circular block 201. As the gear shaft body 3 gradually rises, the tooth surface of the gear shaft body 3 gradually moves upward closer to the first V-shaped tube 6 and the second V-shaped tube 7. At this time, the tooth surface of the gear shaft body 3 can be polished by the polishing component 4. After polishing is completed, the upper circular block 201 can be rotated by the third drive source to polish the next tooth surface. The telescopic component 204 is fixedly installed by the bearing plate 203 and is rotatably connected to the conical guide platform 16, so it does not hinder the rotation of the conical guide platform 16.

[0051] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
