Description

Technical Field

[0001] The present invention relates to the technical field of gear shaft processing equipment, and particularly relates to a processing equipment and processing technology for a new energy direct drive motor gear shaft. Background Art

[0002] With the increasing global emphasis on environmental protection and energy conservation, the new energy vehicle market has developed rapidly. New energy vehicles require efficient and reliable drive systems to support their operation. The direct drive technology is a technology that directly converts electrical energy into mechanical energy, which omits the intermediate drive system, thereby improving the drive efficiency and reliability. With the continuous maturity and wide application of the direct drive technology, the new energy direct drive motor gear shaft has emerged as the times require.

[0003] The processing process of the gear shaft usually includes key steps such as preliminary forming, rough machining, heat treatment, finish machining, surface treatment, and inspection and testing. Among them, heat treatment is an important link to improve the mechanical properties and wear resistance of the gear shaft. Common heat treatment steps include quenching and tempering, carburizing and quenching, and tempering, etc. During the quenching and tempering process, the gear shaft is first heated to a certain high temperature state. Subsequently, quenching is carried out in oil or water to rapidly reduce the temperature and fix its organizational structure, thereby significantly improving the mechanical properties and wear resistance of the gear shaft. However, when the high-temperature gear shaft is put into the quenching oil, a film composed of steam and impurities will rapidly form on its surface. This layer of impurity covering will hinder the effective contact between the quenching oil and the surface of the gear shaft, resulting in uneven cooling during the cooling process, thereby affecting the quenching quality and performance of the gear shaft. In addition, in order to improve the processing efficiency, the quenching of gear shafts is usually carried out in batches and continuously, which leads to a large amount of impurities mixed in the quenching oil, further deteriorating the quenching effect. Over time, these impurities will accumulate and cause more serious adverse effects on the subsequent quenched gear shafts. Based on this, the present invention purposefully provides a processing equipment and processing technology for a new energy direct drive motor gear shaft that can ensure uniform cooling effect during the quenching process of the gear shaft. Summary of the Invention

[0004] The purpose of the present invention is to provide a processing equipment and processing technology for a new energy direct drive motor gear shaft in view of the deficiencies of the prior art, so as to solve the technical problems in the prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions: A processing device for a gear shaft of a new energy direct drive motor, which includes a quenching pool and a lifting frame. The lifting frame is located above the quenching pool. The quenching pool is filled with quenching oil. The top of the lifting frame is connected to an external lifting component. A plurality of U-shaped fixing frames arranged at equal intervals are fixedly installed at the bottom of the lifting frame. A driving component is arranged on the lifting frame. A bearing frame is rotatably installed in the U-shaped fixing frame, and the bearing frame is driven by the driving component to rotate; A locking component is arranged in each bearing frame, and a jack is opened on the bearing frame. A gear shaft body is inserted into the jack. Each gear shaft body is at the same horizontal height. When the gear shaft body is inserted into the jack, the locking component locks the gear shaft body; The external lifting component drives the lifting frame to descend, so that the gear shaft body is immersed in the quenching oil, and then the driving component drives the bearing frame to rotate reciprocally.

[0006] As a further solution of the present invention: The driving component includes a transmission gear, a rack plate and a lifting plate. The transmission gear is rotatably installed on the U-shaped fixing frame, and the transmission gear is coaxially fixedly connected to the rotating shaft of the bearing frame. The rack plate is slidably installed on the U-shaped fixing frame. The rack plate meshes with the transmission gear. The lifting plate is slidably installed in the lifting frame. The bottom of the lifting plate is fixedly connected to the top of the rack plate. The lifting plate is driven by a driving source built in the lifting frame to lift.

[0007] As a further solution of the present invention: The locking component includes a chute, an abutting block and a spring. The chute is opened on the bearing frame and is communicated with the jack. The abutting block is slidably installed in the chute, and the abutting block is connected to the chute through a spring. The pre-tightening force of the spring makes the abutting block move towards the jack. When the gear shaft body is inserted into the jack, the abutting block abuts against the outer cylindrical surface of the gear shaft body, and at this time the spring contracts.

[0008] As a further solution of the present invention: The locking component further includes an inclined edge. The inclined edge is opened at the bottom end of the abutting block. When the gear shaft body is inserted into the jack, the inserted end of the gear shaft body abuts against the inclined edge. As the gear shaft body is inserted, the inserted end of the gear shaft body slides with the inclined edge, so that the abutting block slides upward and compresses the spring.

[0009] As a further solution of the present invention: A discharge pipe is communicated with the quenching pool, and a filter screen is arranged at the connection between the quenching pool and the discharge pipe. The input end of the discharge pipe is communicated with a circulating cooling component. The output end of the circulating cooling component is communicated with a return pipe. A plurality of nozzles are communicated with the return pipe. The nozzles penetrate through the bottom of the quenching pool and are arranged.

[0010] As a further solution of the present invention: When the gear shaft body is above the quenching oil, the horizontal height of the connection between the quenching pool and the discharge pipe is flush with the liquid level of the quenching oil.

[0011] As a further solution of the present invention: the number of the return pipes is multiple, the multiple return pipes are arranged at equal intervals at the bottom of the quenching pool, and there is a gear shaft body between two adjacent nozzles.

[0012] A processing technology for a gear shaft of a new energy direct drive motor, which is applied to a processing device for a gear shaft of a new energy direct drive motor as described above. The technology includes the following steps: Step S1: First, lift the lifting frame by an external lifting component, then insert a heated gear shaft body into the insertion hole of each bearing frame, and fix the gear shaft body through a locking component; Step S2: Subsequently, lift the lifting frame above the quenching oil by an external lifting component, and then control the lifting frame to quickly descend; Step S3: Immerse the gear shaft body quickly into the quenching oil. During this period, small-amplitude lifting can be performed through the external lifting component to drive the gear shaft body to lift and descend in the quenching oil; Step S4: Drive the bearing frame to rotate reciprocally through a driving component, so that the gear shaft body swings reciprocally in the quenching oil; Step S5: Wait for a period of time until the quenching of the gear shaft body is completed, and the external lifting component drives the lifting frame to rise, so as to take out the gear shaft body in the quenching oil. At this time, the gear shaft body can be replaced to perform the next quenching process.

[0013] Advantages of the present invention: 1. In the present invention, the gear shaft body is fixed on a rotatable bearing frame and then quenched in quenching oil. During this period, the driving component drives the bearing frame and the gear shaft body to rotate reciprocally in the quenching oil. This rotation not only further enhances the tearing effect of the inertial force on the surface covering film of the gear shaft body, but more importantly, during the rotation process, the gear shaft body will continuously change its contact state with the quenching oil, making the gear shaft body alternately exposed to the high-temperature oil area and the low-temperature oil area. This alternating exposure method can always ensure that the workpiece gear shaft body can be in contact with the low-temperature quenching oil, thus effectively avoiding the problem that the quenching oil temperature rises due to long-term contact with high-temperature workpieces and ensuring a good quenching effect; 2. In the present invention, all gear shaft bodies adopt an equal-spacing distribution strategy in design and ensure their heights are the same during the quenching process. Such a layout not only reduces the influence of the temperature rise of a single gear shaft body on the adjacent gear shaft bodies around it, but also avoids the problem of uneven cooling caused by the natural convection of the lower-layer oil after heating affecting the upper layer during the traditional multi-layer gear shaft body stacking quenching, resulting in uneven cooling due to the oil temperature gradient change. More importantly, this method of quenching multiple workpieces simultaneously improves production efficiency while ensuring that each workpiece can obtain a uniform and sufficient quenching effect; 3. In the present invention, through the provision of the inclined side, when the gear shaft body is inserted into the jack hole, the insertion end of the gear shaft body abuts against the inclined side, and as the gear shaft body is inserted, the insertion end of the gear shaft body slides along the inclined side, causing the abutting block to slide upward and compress the spring. This eliminates the step of first moving the abutting block into the chute, thus achieving the effect of self-locking. Inserting multiple gear shaft bodies into the jack holes can effectively improve the loading efficiency, thereby shortening the time required for the entire quenching process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 making creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figures 1-8As shown in the figure, the present invention is a processing device for a gear shaft of a new energy direct drive motor, which includes a quenching pool 1 and a lifting frame 2. The lifting frame 2 is located above the quenching pool 1. The quenching pool 1 is filled with quenching oil. The top of the lifting frame 2 is connected to an external lifting component. A plurality of U-shaped fixing frames 3 arranged at equal intervals are fixedly installed at the bottom of the lifting frame 2. A driving component is arranged on the lifting frame 2. A bearing frame 4 is rotatably installed in the U-shaped fixing frame 3, and the bearing frame 4 is driven by the driving component to rotate. A locking component is arranged in each bearing frame 4, and a jack 401 is formed on the bearing frame 4. A gear shaft body 5 is inserted into the jack 401. Each gear shaft body 5 is at the same horizontal height. When the gear shaft body 5 is inserted into the jack 401, the locking component locks the gear shaft body 5. The external lifting component drives the lifting frame 2 to descend, so that the gear shaft body 5 is immersed in the quenching oil, and then the driving component drives the bearing frame 4 to rotate reciprocally.

[0019] In one case of this embodiment, it should be noted that the external lifting component described in the present invention may be a chain drive component including a motor-driven chain, sprocket, guiding device and tensioning device, or a hydraulic drive component including a hydraulic cylinder, hydraulic pump, fuel tank and control valve. The above are all prior arts, and the present invention has not improved them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present invention.

[0020] Working principle of the present invention: First, the lifting frame 2 is lifted by an external lifting component. Then, after the gear shaft body 5 is heated, it is inserted into the jack hole 401, and the gear shaft body 5 is fixed by a locking component until the gear shaft body 5 is inserted into each jack hole 401. Subsequently, the lifting frame 2 is lifted above the quenching oil by the external lifting component, and then the lifting frame 2 is controlled to quickly descend, so that the gear shaft body 5 is quickly immersed in the quenching oil. When the high-temperature gear shaft body 5 contacts the low-temperature quenching oil, a film composed of steam and impurities will quickly form on its surface. At this time, the micro-motion mode of the external lifting device is started to drive the lifting frame 2 and the gear shaft body 5 to perform small-amplitude reciprocating lifting movements. This reciprocating shaking can use the inertial force to tear the covering film on the surface of the gear shaft body 5, so that the quenching oil can directly and fully contact the surface of the gear shaft body 5. At the same time, the driving component drives the carrier 4 and the gear shaft body 5 to rotate reciprocally in the quenching oil. This rotation not only further enhances the tearing effect of the inertial force on the covering film on the surface of the gear shaft body 5, but more importantly, during the rotation process, the gear shaft body 5 will continuously change the contact state between its surface and the quenching oil, so that the gear shaft body 5 is alternately exposed to the high-temperature oil area and the low-temperature oil area (because heat exchange occurs between the gear shaft body 5 and the quenching oil, the surrounding quenching oil will be quickly heated, while the quenching oil far from the gear shaft body 5 has a lower temperature. By rotating the gear shaft body 5, it can move to the low-temperature oil area). This alternating exposure method can always ensure that the workpiece gear shaft body 5 can be in contact with the low-temperature quenching oil, thus effectively avoiding the problem that the quenching oil temperature rises due to long-term contact with high-temperature workpieces and ensuring a good quenching effect; In addition, all the gear shaft bodies 5 adopt an equidistant distribution strategy in design and ensure that their heights are the same during the quenching process. Such a layout not only reduces the influence of the temperature rise of a single gear shaft body 5 on the adjacent gear shaft bodies 5 around it, but also avoids the problem of uneven cooling caused by the natural convection of the upper-layer oil after the lower-layer oil is heated during the traditional multi-layer gear shaft body 5 stacking quenching, which affects the upper layer due to the change of the oil temperature gradient. More importantly, this multi-workpiece simultaneous quenching method improves the production efficiency while ensuring that each workpiece can obtain a uniform and sufficient quenching effect.

[0021] As Figures 1-3 shown, as a preferred embodiment of the present invention, the driving component includes a transmission gear 8, a rack plate 9, and a lifting plate 10. The transmission gear 8 is rotatably installed on the U-shaped fixing frame 3, and the transmission gear 8 is coaxially and fixedly connected to the rotating shaft of the carrier 4. The rack plate 9 is slidably installed on the U-shaped fixing frame 3. The rack plate 9 meshes with the transmission gear 8. The lifting plate 10 is slidably installed in the lifting frame 2. The bottom of the lifting plate 10 is fixedly connected to the top of the rack plate 9. The lifting plate 10 is driven to lift by a driving source built in the lifting frame 2.

[0022] In one case of this embodiment, components such as an electric cylinder or an electric hydraulic rod can be selected as the driving source, and other mechanisms capable of realizing lifting motion can also be selected. This embodiment does not specifically limit this here.

[0023] In the actual application of this embodiment, since the rack plate 9 meshes with the transmission gear 8, when the driving source drives the lifting plate 10 to lift or lower, the lifting plate 10 will drive the rack plate 9 to lift or lower synchronously. Specifically, as Figure 3 shown as an example, when the rack plate 9 rises, it will drive the transmission gear 8 to rotate counterclockwise, thereby driving the carrier 4 to rotate counterclockwise synchronously. At this time, the gear shaft body 5 rotates counterclockwise around the axis of the transmission gear 8. On the contrary, when the rack plate 9 descends, the gear shaft body 5 rotates clockwise around the axis of the transmission gear 8. In fact, the running track of the gear shaft body 5 is a sector. This running mode emphasizes more the tearing effect of the gear shaft body 5 on the covering film thereon, because when the gear shaft body 5 swings rapidly, the quenching oil will be stirred back and forth, and the covering film on the gear shaft body 5 will be washed by the quenching oil.

[0024] As Figures 1-6 shown, as a preferred embodiment of the present invention, the locking assembly includes a chute 402, an abutting block 6 and a spring 7. The chute 402 is opened on the carrier 4 and is communicated with the jack 401. The abutting block 6 is slidably installed in the chute 402, and the abutting block 6 is connected to the chute 402 through the spring 7. The pre-tightening force of the spring 7 causes the abutting block 6 to move towards the jack 401. When the gear shaft body 5 is inserted into the jack 401, the abutting block 6 abuts against the outer cylindrical surface of the gear shaft body 5, and at this time the spring 7 contracts.

[0025] In the actual application of this embodiment, first move the abutting block 6 towards the chute 402 to compress the spring 7 by the abutting block 6, then insert the gear shaft body 5 into the jack 401, and then withdraw the restriction on the abutting block 6. The pre-tightening force of the spring 7 will cause the abutting block 6 to abut against the gear shaft body 5 and apply a force to the gear shaft body 5, and the direction of this force is perpendicular to the axis direction of the gear shaft body 5. As Figure 5 shown, at this time the abutting block 6 abuts against the gear shaft body 5, so that the gear shaft body 5 also tightly abuts against the jack 401, so as to achieve the effect of locking the gear shaft body 5.

[0026] As Figures 1-6 shown, as a preferred embodiment of the present invention, the locking assembly further includes a bevel edge 601 opened at the bottom end of the abutting block 6. When the gear shaft body 5 is inserted into the jack 401, the inserted end of the gear shaft body 5 abuts against the bevel edge 601, and as the gear shaft body 5 is inserted, the inserted end of the gear shaft body 5 slides with the bevel edge 601, so that the abutting block 6 slides upward and compresses the spring 7.

[0027] In actual application of this embodiment, through the setting of the bevel edge 601, when the gear shaft body 5 is inserted into the jack 401, the insertion end of the gear shaft body 5 abuts against the bevel edge 601, and as the gear shaft body 5 is inserted, the insertion end of the gear shaft body 5 slides on the bevel edge 601, so that the abutting block 6 slides upward and compresses the spring 7, eliminating the step of first moving the abutting block 6 into the chute 402. In this way, the effect of self-locking can be achieved, and when multiple gear shaft bodies 5 are inserted into the jacks 401, the loading efficiency can be effectively improved, thereby shortening the time required for the entire quenching process.

[0028] As Figures 1-8 As shown, as a preferred embodiment of the present invention, a discharge pipe 11 is communicated with the quenching pool 1, and a filter screen 15 is arranged at the connection between the quenching pool 1 and the discharge pipe 11. The input end of the discharge pipe 11 is communicated with the circulating cooling assembly 12, the output end of the circulating cooling assembly 12 is communicated with a return pipe 13, and a plurality of nozzles 14 are communicated with the return pipe 13. The nozzles 14 are arranged through the bottom of the quenching pool 1.

[0029] In one case of this embodiment, it should be noted that the circulating cooling assembly 12 described in the present invention includes an oil pump, an air-cooled cooler, a valve, a temperature sensor, etc. The above components are all prior arts, and the present invention has not improved them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present invention.

[0030] In actual application of this embodiment, during continuous quenching operation, the temperature of the quenching oil will gradually increase. At this time, the circulating cooling assembly 12 is started, and the high-temperature quenching oil in the quenching pool 1 is sucked through the discharge pipe 11, and then cooled by the circulating cooling assembly 12. The low-temperature quenching oil is injected from the bottom of the quenching pool 1 through the return pipe 13 and the nozzles 14. In this way, it is ensured that the quenching oil in the quenching pool 1 is always maintained at a low temperature to ensure the quenching effect. And continuous quenching operation will cause a lot of impurities to be mixed into the quenching oil. When the discharge pipe 11 sucks the quenching oil, the impurities will also move towards the discharge pipe 11, and the filter screen 15 will intercept the impurities to prevent the impurities from entering the circulating cooling assembly 12. At the same time, the impurities are gathered at the filter screen 15, which is convenient for workers to fish out the impurities, thereby purifying the quenching oil. Moreover, the flowing quenching oil can also wash the covering film on the surface of the gear shaft body 5 to improve the quenching effect.

[0031] As Figures 1-8 As shown, as a preferred embodiment of the present invention, when the gear shaft body 5 is above the quenching oil, the horizontal height at the connection between the quenching pool 1 and the discharge pipe 11 is flush with the liquid level of the quenching oil.

[0032] In practical application of this embodiment, during the quenching operation, the oil temperature of the quenching oil gradually rises. The natural convection generated by the rising oil temperature causes the high-temperature quenching oil to be located at the top layer. When the gear shaft body 5 is located above the quenching oil, the horizontal height of the connection between the quenching pool 1 and the discharge pipe 11 is flush with the liquid level of the quenching oil. When the gear shaft body 5 enters the quenching oil, the liquid level of the quenching oil will rise. At this time, the discharge pipe 11 sucks the quenching oil at the top layer. In continuous quenching operations, the high-temperature quenching oil is sucked away first, and then low-temperature quenching oil is injected into the quenching pool 1 through the nozzle 14, thereby quickly reducing the temperature of the quenching oil in the quenching pool 1.

[0033] As Figures 1-8 shown, as a preferred embodiment of the present invention, the number of the return pipes 13 is multiple. The multiple return pipes 13 are arranged at equal intervals at the bottom of the quenching pool 1, and there is a gear shaft body 5 between two adjacent nozzles 14.

[0034] In practical application of this embodiment, as Figure 8 shown for example, there is a gear shaft body 5 between every two nozzles 14. When the nozzle 14 injects low-temperature quenching oil, the low-temperature quenching oil will wrap the middle gear shaft body 5 from both sides to ensure that the gear shaft body 5 comes into contact with the low-temperature quenching oil.

[0035] Please refer to Figures 1-8 shown. The present invention is a processing technology for a gear shaft of a new energy direct drive motor. The technology is applied to a processing device for a gear shaft of a new energy direct drive motor as described in the above embodiment. The technology includes the following steps: Step S1: First, lift the lifting frame 2 through an external lifting component, then insert a heated gear shaft body 5 into the insertion hole 401 of each carrier frame 4, and fix the gear shaft body 5 through a locking component. Step S2: Subsequently, lift the lifting frame 2 above the quenching oil through an external lifting component, and then control the lifting frame 2 to quickly descend. Step S3: Immerse the gear shaft body 5 quickly into the quenching oil. During this period, small-amplitude lifting can be performed through the external lifting component to drive the gear shaft body 5 to lift and lower in the quenching oil. Step S4: Drive the carrier frame 4 to rotate reciprocally through the driving component, so that the gear shaft body 5 swings reciprocally in the quenching oil. Step S5: Wait for a period of time until the quenching of the gear shaft body 5 is completed. The external lifting component drives the lifting frame 2 to rise, thereby taking out the gear shaft body 5 in the quenching oil. At this time, the gear shaft body 5 can be replaced to perform the next quenching process.

[0036] The above has described in detail an embodiment of the present invention, but the above content is only a preferred embodiment of the present invention and cannot be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
