Description

Technical Field

[0001] This invention belongs to the field of transmission shaft turning technology, specifically a new energy vehicle transmission shaft turning equipment. Background Technology

[0002] New energy vehicle drive shafts are key shaft components used in the power systems of new energy vehicles (pure electric, hybrid, etc.) to connect the motor output end with the drive actuator (drive axle, wheels). Their essence is mainly to withstand and transmit torque and speed, while adapting to the chassis space layout. They need to meet characteristics such as lightweight, high-precision dynamic balance, and high torque load capacity, which are different from the heavy-duty and low-speed adaptation design of traditional fuel vehicle drive shafts.

[0003] A patent application with publication number CN114769628A discloses a drive shaft turning device. Through the cooperation of sliding components and fixed components, it is possible to continue machining the other side of the rotating shaft without disassembly. This reduces the time spent changing the fixed rotating shaft and improves work efficiency.

[0004] In current technologies, turning a drive shaft generates cutting threads. As the drive shaft continues to rotate during turning, these threads, due to their excessive length, may break due to uneven stress during rotation. The resulting short chips are then flung outwards by the impact of the cutting force. During this splashing process, these cutting threads may scratch the machined drive shaft surface due to their trajectory, affecting the surface finish and precision of the workpiece. This not only hinders workpiece machining but also negatively impacts the turning environment.

[0005] Therefore, the present invention provides a turning equipment for machining drive shafts of new energy vehicles. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a new energy vehicle drive shaft machining turning equipment, including a cylindrical box, feeding devices symmetrically arranged on both sides of the cylindrical box, turning cutter heads arranged on the top of both feeding devices, a positioning and material replacement device arranged on the top of the cylindrical box, cover plates symmetrically fixedly installed at both ends of the cylindrical box, and a ring plate arranged between the two cover plates and the cylindrical box, a rotating assembly arranged inside the cylindrical box, the rotating assembly being used to drive the drive shaft to rotate, a slag-collecting assembly arranged inside the two cover plates, the slag-collecting assembly including a slag-collecting ring, the slag-collecting assembly being used to drive the slag-collecting ring to collect the turning filaments, and a ring-stop assembly arranged inside the two cover plates, the two ring-stop assemblies being respectively placed on one side of the two slag-collecting assemblies, the ring-stop assemblies being used to block the turning filaments when the drive shaft is being turned; When the drive shaft needs to be turned, the positioning and material replacement device moves the drive shaft, aligning it centrally within the cylinder. The rotating assembly then drives the drive shaft to rotate. As the drive shaft rotates, the feed device moves the turning cutter heads, which select appropriate cutting tools to turn both ends of the drive shaft, thus completing the turning operation. While the tools are cutting the drive shaft, the ring retainer assembly blocks the cutting threads generated during turning, preventing them from splashing into the cylinder and damaging internal components. Simultaneously, the slag-collecting assembly, driven by a slag-collecting ring, collects the cutting threads from the drive shaft inside the cover plate. The slag collection system allows for the collection of flying slag when the cutting tool is turning the drive shaft. When the turning operation is finished, the feed device drives the cutting head to return to its original position, and the positioning and replacement device removes the turned drive shaft from the cylinder and simultaneously inserts a new drive shaft. This enables continuous turning operations on the drive shaft of new energy vehicles. Through the cooperation of the slag collection component and the ring retainer component, secondary flying slag can be prevented from scratching the machined surface of the drive shaft, ensuring the surface finish of the shaft. At the same time, it can prevent chips from remaining inside the machine tool and affecting the motion accuracy of the equipment. It can also prevent the flying slag from splashing outside the turning equipment and affecting the turning environment, keeping the turning environment clean and reducing the cleaning burden.

[0008] Preferably, the rotating assembly includes two guide rails, each with three electric sliders slidably mounted inside. Three retaining boxes are rotatably mounted inside the cylinder, each located within one of the two guide rails. Each retaining box contains a fixing block, and all three retaining boxes have identical internal structures. A connecting block is mounted on the top of each retaining box. The outer walls of the electric sliders are fixedly connected in pairs to the outer walls of the three connecting blocks. When the positioning and material-replacing device aligns the drive shaft inside the cylinder, it pushes the fixing blocks out of the retaining boxes and onto the surface of the drive shaft. When the fixing blocks are against the drive shaft surface, the electric sliders rotate within the guide rails, causing the connecting blocks to rotate. The connecting blocks, in turn, drive the drive shaft to rotate via the fixing blocks, thus achieving the rotation of the drive shaft and enabling its rotation.

[0009] Preferably, multiple electric telescopic rods are fixedly installed on the inner wall of the positioning box. The output ends of the multiple electric telescopic rods are all fixedly connected to the outer wall of the fixing block. When the positioning and material replacement device aligns and places the drive shaft in the cylinder, the electric telescopic rods are driven to work. The electric telescopic rods will drive the fixing block to extend out of the positioning box, so that the fixing block moves slowly and fits against the outer wall of the drive shaft. When the bottom of the three fixing blocks all contacts the outer wall of the drive shaft, the three fixing blocks will fix the drive shaft in a central fixing manner, thus playing the role of fixing and connecting the drive shaft.

[0010] Preferably, each of the three fixing blocks has a foot pad fixedly installed on its bottom. The outer wall of each of the three foot pads can fit against the outer wall of the drive shaft. When the fixing block moves towards the drive shaft to fit against it, the fixing block will drive the foot pad to move towards the drive shaft to fit against it. When all three foot pads are in contact with the outer wall of the drive shaft, the three fixing blocks will fix the drive shaft through the foot pads. The foot pads are designed to avoid surface indentations and damage, and to provide cushioning and shock absorption, thereby improving the stability during clamping and enabling the fixing blocks to better clamp and fix the drive shaft, thus playing a role in relieving pressure on the drive shaft.

[0011] Preferably, the slag-collecting assembly further includes multiple oblique flow blocks, each fixedly installed on the inner wall of the slag-collecting ring. An arc-shaped oblique guide groove is formed between the multiple oblique flow blocks. A limit ring is fixedly installed inside the cover plate, with one end of the limit ring fixedly connected to one side of the cover plate. The outer wall of the slag-collecting ring is rotatably connected to the inner wall of the limit ring. The drive shaft is placed inside the slag-collecting ring. When the drive shaft rotates, it drives the slag-collecting ring to rotate in the opposite direction to the rotation of the drive shaft outside the drive shaft. The slag-collecting ring will then drive the oblique flow blocks to rotate in the opposite direction to the drive shaft on the limit ring. By rotating in opposite directions, the centrifugal force of the reverse rotation is opposed to the direction of the debris splashing, which can throw the turning wire and other debris into the arc-shaped inclined guide groove formed between multiple inclined blocks. Finally, as the slag-collecting ring continues to rotate, the turning wire and other debris will gather and collect along the guiding direction of the arc-shaped inclined guide groove, which plays the role of slag collection. This can reduce the probability of debris rebounding back to the cutting zone, reduce the risk of scratches and burrs on the surface during the turning of the drive shaft, and at the same time generate shearing force to quickly peel off the debris in the cutting zone.

[0012] Preferably, the outer walls of multiple electric sliders are fixedly mounted with shafts, and the outer walls of the multiple shafts are rotatably connected to the inner walls of the ring plate and the guide rail. An internal gear ring is rotatably connected to the inner wall of the cover plate, and an external gear ring is fixedly mounted to the outer wall of the slag-collecting ring. One end of each of the multiple shafts is fixedly connected to the outer wall of the internal gear ring. Multiple gears are rotatably connected to one side of the ring plate. The multiple gears are positioned between the external gear ring and the internal gear ring, and the teeth on the multiple gears can respectively mesh with the teeth on the external gear ring and the internal gear ring. When the electric slider drives the transmission shaft to rotate through the fixed block, the electric slider will drive the internal gear ring to rotate together through the shafts. When the internal gear ring rotates, the internal gear ring will drive the gear to rotate. Through the meshing of the gear teeth, when the gear rotates, the gear will drive the external gear ring to rotate in the opposite direction, thereby causing the external gear ring to rotate in the opposite direction to the transmission shaft, thus achieving the effect of driving the slag-collecting ring to rotate in the opposite direction while the transmission shaft rotates.

[0013] Preferably, the ring retaining assembly includes a grooved ring, which is fixedly installed between the ring plate and the limiting ring. Two slag-blocking rings are symmetrically slidably arranged inside the grooved ring. Multiple pressure springs are provided between the outer wall of the two slag-blocking rings and the inner wall of the grooved ring. When the drive shaft is placed, by pushing the two slag-blocking rings to move relative to each other, the two slag-blocking rings will squeeze the pressure springs in the grooved rings and move, thereby opening the gap between the two slag-blocking rings. When the drive shaft is placed in the cylinder, by stopping the pushing of the two slag-blocking rings, the two slag-blocking rings will return to their original position under the elastic push of the pressure springs. The inner wall of the two slag-blocking rings will then fit against the outer wall of the drive shaft, thereby achieving a barrier between the machined part of the drive shaft and the inside of the cylinder, preventing the cutting chips generated during machining from splashing into the cylinder, and playing a role in blocking the cutting chips.

[0014] Preferably, both slag-blocking rings have a slanted arc-shaped sliding opening at their tops. When the cutting chips are splashing, they are blocked by the two slag-blocking rings and placed outside the rings. Combined with the shearing force generated by the rotation of the drive shaft and the counter-rotation between the slag-collecting rings, the cutting chips flow along the direction of the slanted arc-shaped sliding opening. The slanted arc-shaped sliding opening replaces the hard obstruction of the traditional flat slag-blocking ring. The arc-shaped inclined structure guides the directional flow of the chips, preventing them from bouncing back after hitting the slag-blocking rings and causing secondary splashing that scratches the machined surface of the drive shaft. At the same time, the static obstruction of the slag-blocking rings and the dynamic rotation and collection of the slag-collecting rings are seamlessly connected by the slanted arc-shaped sliding opening. The chips do not need to fall randomly and can enter the guide channel, improving collection efficiency and preventing chips from remaining in the gap between the two.

[0015] Preferably, each of the two slag-blocking rings has a sliding groove at one end and a sliding shaft fixedly installed at the other end. The two slag-blocking rings are slidably connected to each other, and the outer walls of the two sliding shafts are slidably connected to the inner walls of the two sliding grooves. When the two slag-blocking rings move relative to each other, the sliding shaft between the two slag-blocking rings will slide in the sliding groove. The two slag-blocking rings will then slide together through the sliding shaft and the sliding groove to form a retractable annular structure. With the elastic push of the pressure spring, the two slag-blocking rings will always form a complete slag-blocking ring, providing a sliding basis for the relative sliding between the two slag-blocking rings.

[0016] Preferably, a slag flow chamber pipe is fixedly installed on the inner wall of the limiting ring, and a slag storage box is fixedly installed at the bottom end of the slag flow chamber pipe. The slag flow chamber pipe is connected to the limiting ring, and the top of the slag storage box is placed between the slag gathering ring and the groove ring. When the slag gathering ring drives the turning chips to gather through the inclined flow blocks, the gathered turning chips will move along the direction of the arc-shaped inclined guide grooves opened between the multiple inclined flow blocks. The turning chips will flow and gather between the slag gathering ring and the groove ring. With the help of the inclined arc sliding mouth on the slag blocking ring to block and guide the turning chips, the turning chips will finally be placed between the groove ring and the slag gathering ring, and finally fall into the slag storage box along the slag flow chamber pipe for collection and storage, thus playing the role of storing turning chips.

[0017] The beneficial effects of this invention are as follows: 1. The new energy vehicle drive shaft machining turning equipment of the present invention, through the cooperation of the slag collection component and the ring retainer component, can avoid secondary splashing of turning wires and scratching the machined surface of the drive shaft, ensuring the surface finish of the shaft body. At the same time, it can prevent the chips from remaining inside the machine tool and affecting the motion accuracy of the equipment. It can also prevent the turning wires from splashing outside the turning equipment and affecting the turning environment, keeping the turning environment clean and reducing the cleaning burden.

[0018] 2. The new energy vehicle drive shaft machining turning equipment of the present invention drives a slag-collecting ring to rotate in the opposite direction to the rotation of the drive shaft outside the shaft. The direction of the centrifugal force of the reverse rotation is opposed to the direction of chip splashing, which can throw the turning wire and other chips into the arc-shaped inclined guide groove formed between multiple inclined blocks. Finally, with the continuous rotation of the slag-collecting ring, the turning wire and other chips will be gathered and collected along the guiding direction of the arc-shaped inclined guide groove, which can reduce the probability of chips rebounding back to the cutting zone, reduce the risk of scratches and burrs on the surface during the turning of the drive shaft, and at the same time generate shearing force to quickly peel off the chips in the cutting zone.

[0019] 3. The new energy vehicle drive shaft machining turning equipment of the present invention, when the drive shaft is placed, pushes two slag-blocking rings to move relative to each other. The two slag-blocking rings will move by squeezing the bearing spring in the groove ring, thereby opening the two slag-blocking rings. When the drive shaft is placed in the cylinder, by stopping the push of the two slag-blocking rings to move, the two slag-blocking rings will return to their original position under the elastic push of the bearing spring. The inner wall of the two slag-blocking rings will then fit against the outer wall of the drive shaft, preventing the cutting chips generated during turning from splashing into the cylinder.

[0020] 4. The new energy vehicle drive shaft machining turning equipment of the present invention uses two slag-blocking rings to block the splashing turning chips, and the turning chips will flow along the opening direction of the inclined arc slide. The inclined arc slide replaces the hard blocking of the traditional flat slag-blocking ring. The arc-shaped inclined structure guides the chips to flow in a direction, avoiding the chips from rebounding after hitting the slag-blocking ring and forming secondary splashing that scratches the machined surface of the drive shaft. At the same time, the static blocking of the slag-blocking ring and the dynamic rotational collection of the slag-collecting ring are seamlessly connected through the inclined arc slide. The chips do not need to fall in a disorderly manner to enter the guide channel, improving the collection efficiency and avoiding the chips remaining in the gap between the two.

[0021] 5. In the new energy vehicle drive shaft machining turning equipment described in this invention, when the fixing block moves and fits against the drive shaft, the fixing block will drive the foot pads to move and fit against the drive shaft. When all three foot pads contact the outer wall of the drive shaft, the three fixing blocks will fix the drive shaft through the foot pads. The foot pads are designed to avoid surface indentations and damage, and to provide cushioning and shock absorption, thereby improving the stability during clamping and allowing the fixing blocks to better clamp and fix the drive shaft, thus playing a role in relieving pressure on the drive shaft.

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 9 As shown in the embodiment of the present invention, a new energy vehicle drive shaft machining turning equipment includes a cylindrical box 1. Feeding devices 301 are symmetrically arranged on both sides of the cylindrical box 1. A turning cutter disc 3 is arranged on the top of each of the two feeding devices 301. A positioning and material replacement device 2 is arranged on the top of the cylindrical box 1. Cover plates 11 are symmetrically fixedly installed at both ends of the cylindrical box 1. A ring plate 101 is arranged between the two cover plates 11 and the cylindrical box 1. A rotating assembly is arranged inside the cylindrical box 1. The rotating assembly is used to drive the drive shaft to rotate in a fixed manner. A slag-collecting assembly is arranged inside each of the two cover plates 11. The slag-collecting assembly includes a slag-collecting ring 9. The slag-collecting assembly is used to drive the slag-collecting ring 9 to collect the turning filaments. A ring-blocking assembly is arranged inside each of the two cover plates 11. The two ring-blocking assemblies are respectively placed on one side of the two slag-collecting assemblies. The ring-blocking assemblies are used to block the turning filaments when the drive shaft is being turned. During the turning process, the cutting wire may break due to uneven force during rotation due to its excessive length. This causes the short chips to fly in all directions under the impact of the cutting force. These cutting wires may scratch the surface of the machined drive shaft due to the trajectory of the flying wires, thus affecting the surface finish and accuracy of the workpiece. This is not only detrimental to the machining of the workpiece, but also has a certain impact on the turning environment. When the drive shaft needs to be turned, the positioning and material replacement device 2 moves the drive shaft, aligning it centrally within the cylindrical housing 1. The rotating assembly then drives the drive shaft to rotate. As the drive shaft rotates, the feed device 301 moves the turning tool discs 3, which select appropriate cutting tools to turn both ends of the drive shaft, thus completing the turning operation. When the cutting tool cuts the drive shaft, the ring retainer assembly blocks the cutting wires generated during turning, preventing them from splashing into the cylindrical housing 1. Damage to the components is caused, and at the same time, the slag-collecting component drives the slag-collecting ring 9 to collect the cutting shavings cut from the drive shaft inside the cover plate 11. This allows for the collection of flying cutting shavings when the tool is turning the drive shaft. When the turning operation is finished, the feed device 301 drives the turning tool disc 3 to return to its original position, and the positioning and replacement device 2 will remove the turned drive shaft from the cylinder 1 and insert a new drive shaft, thus enabling continuous turning operations on the drive shaft of new energy vehicles. Through the cooperation of the slag-collecting component and the ring retainer component, secondary flying cutting shavings can be prevented from scratching the machined surface of the drive shaft, ensuring... The smooth surface of the shaft body prevents chips from remaining inside the machine tool, affecting the accuracy of the equipment's movement, and also prevents cutting threads from splashing onto the outside of the turning equipment, thus maintaining a clean turning environment and reducing cleaning burden. It should be noted that the positioning and material replacement device 2 consists of a loading / unloading mechanism and a positioning mechanism. The loading / unloading mechanism is used to place the drive shaft into and remove it from the cylinder 1. The positioning mechanism is used to center-align the drive shaft with the cylinder 1. The loading mechanism can consist of a robotic arm and a vision sensor, while the positioning mechanism can be driven by a synchronous motor to operate two alignment push plates. The turning tool disc 3 is equipped with... The rotary tool assembly, used to rotate and select a suitable tool for turning the drive shaft, can be composed of a motor, a connecting rod, and a tool holder. The feed device 301 is equipped with a feed component, which is used to drive the tool on the turning tool disc 3 to move and feed the drive shaft in the cylinder 1 for turning. It is composed of a sliding block and a positioning sensor. All three are existing technologies, so they are only described in this solution and their specific structures are not shown. The guide form of the feed device 301 is set to an L-shaped movement form, mainly to avoid motion interference between the turning tool disc 3 and the positioning replacement device 2 when the turning of the drive shaft is finished and the loading and unloading mechanism in the positioning replacement device 2 replaces the drive shaft.

[0027] like Figures 1 to 9 As shown, the rotating assembly includes two guide rails 4. Three electric sliders 401 are slidably arranged inside each of the two guide rails 4. Three retaining boxes 6 are rotatably arranged inside the cylinder 1. The three retaining boxes 6 are all arranged inside the two guide rails 4. The three retaining boxes 6 are all provided with fixing blocks 603 inside the three retaining boxes 6. The internal structure of the three retaining boxes 6 is the same. The top of the three retaining boxes 6 is provided with connecting blocks 601. The outer walls of the multiple electric sliders 401 are fixedly connected to the outer walls of the three connecting blocks 601 in pairs. When the positioning and replacement device 2 aligns and places the drive shaft inside the cylinder 1, it pushes the fixing block 603 out of the fixing box 6 and attaches it to the surface of the drive shaft. When the fixing block 603 is attached to the surface of the drive shaft, it drives the electric slider 401 to rotate in the guide rail 4. The electric slider 401 will drive the connecting block 601 to rotate, and the connecting block 601 will drive the drive shaft to rotate through the fixing block 603, thereby realizing the rotation operation of the drive shaft and playing the role of driving the drive shaft to rotate. It should be noted that when the electric slider 401 just moves, the positioning mechanism in the positioning and replacement device 2 will continue to drive the drive shaft to center alignment in the cylinder 1. When the fixing block 603 is attached to the drive shaft, the positioning mechanism will separate from the drive shaft to ensure that the two ends of the drive shaft are placed symmetrically in the cylinder 1, ensuring the stability and accuracy of the placement, and also facilitating the turning operation of the drive shaft by the cutting tool.

[0028] like Figures 8 to 9 As shown, multiple electric telescopic rods 602 are fixedly installed on the inner wall of the fixed box 6, and the output ends of the multiple electric telescopic rods 602 are all fixedly connected to the outer wall of the fixed block 603. When the positioning and material replacement device 2 aligns and places the drive shaft inside the cylinder 1, it operates by driving the electric telescopic rod 602. The electric telescopic rod 602 will then drive the fixing block 603 to extend out from the fixing box 6, so that the fixing block 603 slowly moves and fits against the outer wall of the drive shaft. When the bottom of the three fixing blocks 603 all contact the outer wall of the drive shaft, the three fixing blocks 603 will fix the drive shaft in a central fixing manner, thus playing the role of fixing and connecting the drive shaft.

[0029] like Figures 8 to 9 As shown, foot pads 604 are fixedly installed on the bottom of the three fixing blocks 603, and the outer walls of the three foot pads 604 can fit and contact the outer wall of the drive shaft. When the fixing block 603 moves and fits against the drive shaft, the fixing block 603 will drive the foot pads 604 to move and fit against the drive shaft. When all three foot pads 604 are in contact with the outer wall of the drive shaft, the three fixing blocks 603 will fix the drive shaft through the foot pads 604. The foot pads 604 are designed to avoid surface indentations and damage, and to provide cushioning and shock absorption, thereby improving the stability during clamping. This allows the fixing blocks 603 to better clamp and fix the drive shaft, thus playing a role in relieving pressure on the drive shaft. It should be noted that the foot pads 604 are made of rubber material.

[0030] like Figures 4 to 6 As shown, the slag-collecting assembly also includes a plurality of inclined flow blocks 901. The plurality of inclined flow blocks 901 are fixedly installed on the inner wall of the slag-collecting ring 9. An arc-shaped inclined guide groove is formed between the plurality of inclined flow blocks 901. A limit ring 5 is fixedly installed inside the cover plate 11. One end of the limit ring 5 is fixedly connected to one side of the cover plate 11. The outer wall of the slag-collecting ring 9 is rotatably connected to the inner wall of the limit ring 5. The drive shaft is placed inside the slag-collecting ring 9. When the drive shaft rotates, the slag-collecting ring 9 rotates in the opposite direction to the drive shaft outside the drive shaft. The slag-collecting ring 9 then drives the inclined flow block 901 to rotate in the opposite direction to the drive shaft on the limiting ring 5. Through the reverse rotation between the two, the direction of the centrifugal force of the reverse rotation is opposed to the direction of the chip splash, which can throw the turning wire and other chips into the arc-shaped inclined guide groove formed between multiple inclined flow blocks 901. Finally, with the continuous rotation of the slag-collecting ring 9, the turning wire and other chips will gather and collect along the guiding direction of the arc-shaped inclined guide groove, which can play the role of slag collection. This can reduce the probability of chips rebounding back to the cutting zone, reduce the risk of scratches and burrs on the surface during the turning of the drive shaft, and at the same time, it can also generate shearing force to quickly peel off the chips in the cutting zone.

[0031] like Figures 4 to 6 As shown, a shaft 402 is fixedly installed on the outer wall of a plurality of electric sliders 401. The outer wall of the plurality of shafts 402 can be rotatably connected to the inner wall of the ring plate 101 and the guide rail 4. An internal toothed ring 8 is rotatably connected to the inner wall of the cover plate 11. An external toothed ring 801 is fixedly installed on the outer wall of the slag-collecting ring 9. One end of the plurality of shafts 402 is fixedly connected to the outer wall of the internal toothed ring 8. A plurality of gears 802 are rotatably connected to one side of the ring plate 101. The plurality of gears 802 are all placed between the external toothed ring 801 and the internal toothed ring 8, and the teeth on the plurality of gears 802 can respectively mesh with the teeth on the external toothed ring 801 and the internal toothed ring 8. When the electric slider 401 drives the transmission shaft to rotate via the fixed block 603, the electric slider 401 will drive the internal gear ring 8 to rotate together via the shaft 402. When the internal gear ring 8 rotates, it will drive the gear 802 to rotate. Through the meshing of the teeth of the gear 802, when the gear 802 rotates, it will drive the external gear ring 801 to rotate in the opposite direction, thereby causing the external gear ring 801 to drive the slag-collecting ring 9 to rotate in the opposite direction to the transmission shaft, thus achieving the effect of driving the slag-collecting ring 9 to rotate in the opposite direction while the shaft rotates.

[0032] like Figures 6 to 8 As shown, the ring baffle assembly includes a grooved ring 10, which is fixedly installed between the ring plate 101 and the limiting ring 5. Two slag-blocking rings 1001 are symmetrically slidably arranged inside the grooved ring 10. Multiple pressure-bearing springs 1002 are provided between the outer wall of the two slag-blocking rings 1001 and the inner wall of the grooved ring 10. When the drive shaft is placed, by pushing the two slag-blocking rings 1001 to move relative to each other, the two slag-blocking rings 1001 will squeeze the pressure spring 1002 within the grooved ring 10 and move, thereby opening the gap between the two slag-blocking rings 1001. When the drive shaft is placed inside the cylinder 1, by stopping the movement of the two slag-blocking rings 1001, the two slag-blocking rings 1001 will return to their original position under the elastic push of the pressure spring 1002. The inner walls of the two slag-blocking rings 1001 will then fit against the outer wall of the drive shaft, thereby achieving a barrier between the machined part of the drive shaft and the inside of the cylinder 1, preventing the cutting chips generated during machining from splashing into the cylinder 1, and playing a role in blocking the cutting chips. The elastic push of the pressure spring 1002 pushes the slag-blocking rings 1001 to fit against the outer wall of the drive shaft for blocking. With the help of the electric telescopic rod 602, the fixing block 603 is fixed to the drive shaft, so that this device can perform machining operations on drive shafts of various diameters during operation, improving the adaptability of the device.

[0033] like Figures 7 to 8 As shown, the top of both slag-blocking rings 1001 is provided with a slanted arc sliding opening 1003; When the turning chips are splashing, they are blocked by two chip-blocking rings 1001 and placed outside the two chip-blocking rings 1001. Combined with the shearing force generated by the rotation of the drive shaft and the counter-rotation between the chip-collecting ring 9, the turning chips will flow along the opening direction of the inclined arc slide 1003. The inclined arc slide 1003 replaces the hard obstruction of the traditional flat retaining ring. The arc-shaped inclined structure guides the directional flow of chips, avoiding the chips from rebounding after hitting the retaining ring and forming secondary splashes that scratch the machined surface of the drive shaft. At the same time, the static obstruction of the chip-blocking ring 1001 and the dynamic rotation collection of the chip-collecting ring 9 are seamlessly connected by the inclined arc slide 1003. The chips do not need to be scattered in a disorderly manner to enter the guide channel, improving the collection efficiency and avoiding the chips remaining in the gap between the two.

[0034] like Figures 7 to 8 As shown, each of the two slag-blocking rings 1001 has a sliding groove 1005 at one end, and a sliding shaft 1004 is fixedly installed at the other end of each of the two slag-blocking rings 1001. The two slag-blocking rings 1001 are slidably connected to each other at their ends, and the outer walls of the two sliding shafts 1004 are slidably connected to the inner walls of the two sliding grooves 1005 respectively. When the two slag-blocking rings 1001 move relative to each other, the sliding shaft 1004 between the ends of the two slag-blocking rings 1001 will slide in the sliding groove 1005. The two slag-blocking rings 1001 will slide and fit together with the sliding shaft 1004 and the sliding groove 1005 to form a retractable ring structure. With the elastic push of the pressure spring 1002, the two slag-blocking rings 1001 will always form a complete slag-blocking ring, which will provide a sliding basis for the relative sliding between the two slag-blocking rings 1001.

[0035] like Figures 1 to 6 As shown, a slag flow chamber pipe 701 is fixedly installed on the inner wall of the limiting ring 5, and a slag storage box 7 is fixedly installed at the bottom end of the slag flow chamber pipe 701. The slag flow chamber pipe 701 is connected to the limiting ring 5, and the top of the slag storage box 7 is placed between the slag accumulation ring 9 and the groove ring 10. When the slag-gathering ring 9 gathers the turning chips through the inclined flow block 901, the gathered turning chips will move along the direction of the arc-shaped inclined guide groove opened between the multiple inclined flow blocks 901. The turning chips will flow and gather between the slag-gathering ring 9 and the groove ring 10. With the help of the inclined arc sliding mouth 1003 on the slag-blocking ring 1001 to block and guide the turning chips, the turning chips will finally be placed between the groove ring 10 and the slag-gathering ring 9, and finally fall into the slag storage box 7 along the slag flow chamber pipe 701 for collection and storage, thus playing the role of storing turning chips.

[0036] Working principle: When the drive shaft needs to be turned, the positioning and material replacement device 2 drives the drive shaft to move, and the positioning and material replacement device 2 will assemble the drive shaft into the cylinder 1 in a center-aligned manner. Then, the rotating component can drive the drive shaft to rotate. When the drive shaft rotates, the driving feed device 301 drives the turning cutter head 3 to move for feed. The two turning cutter heads 3 will select appropriate turning tools to turn both ends of the drive shaft, thereby realizing the turning operation of the drive shaft. When the tool cuts the drive shaft, the ring retaining component blocks the turning wire generated by turning, preventing the turning wire from splashing into the cylinder 1 and damaging the components inside the cylinder 1. At the same time, the slag collection component drives the slag collection ring 9 inside the cover plate 11 to cut the slag off the drive shaft. By collecting and gathering the cutting shavings, the cutting shavings that splash out when the tool is turning the drive shaft can be collected and gathered. When the turning operation is finished, the feed device 301 drives the turning tool head 3 to return to its original position, and the positioning and material replacement device 2 will take out the turned drive shaft from the cylinder 1 and put in a new drive shaft. This enables continuous turning operation of the drive shaft of new energy vehicles. Through the cooperation of the shavings collection component and the ring retainer component, the secondary splashing of cutting shavings can be avoided to scratch the machined surface of the drive shaft, ensuring the surface finish of the shaft. At the same time, it can prevent the chips from remaining inside the machine tool and affecting the motion accuracy of the equipment. It can also prevent the cutting shavings from splashing outside the turning equipment and affecting the turning environment, keeping the turning environment clean and reducing the cleaning burden. When the positioning and replacement device 2 aligns and places the drive shaft in the cylinder 1, it pushes the fixing block 603 out of the fixing box 6 and attaches it to the surface of the drive shaft. When the fixing block 603 is attached to the surface of the drive shaft, it drives the electric slider 401 to rotate in the guide rail 4. The electric slider 401 will drive the connecting block 601 to rotate, and the connecting block 601 will drive the drive shaft to rotate through the fixing block 603, thereby realizing the rotation operation of the drive shaft and playing the role of driving the drive shaft to rotate. When the positioning and material replacement device 2 aligns and places the drive shaft in the cylinder 1, it operates by driving the electric telescopic rod 602. The electric telescopic rod 602 will drive the fixing block 603 to extend out of the fixing box 6, so that the fixing block 603 slowly moves and fits against the outer wall of the drive shaft. When the bottom of the three fixing blocks 603 all contact the outer wall of the drive shaft, the three fixing blocks 603 will fix the drive shaft in the form of central fixation, thus playing the role of fixing and connecting the drive shaft. When the fixing block 603 moves and fits against the drive shaft, the fixing block 603 will drive the foot pad 604 to move and fit against the drive shaft. When all three foot pads 604 are in contact with the outer wall of the drive shaft, the three fixing blocks 603 will fix the drive shaft through the foot pads 604. The foot pads 604 are designed to avoid surface indentations and damage and to provide cushioning and shock absorption, improve the stability during clamping, and enable the fixing blocks 603 to better clamp and fix the drive shaft, thus playing the role of relieving pressure on the drive shaft. When the drive shaft rotates, the slag-collecting ring 9 rotates in the opposite direction to the drive shaft outside the drive shaft. The slag-collecting ring 9 will drive the inclined flow block 901 to rotate in the opposite direction to the drive shaft on the limiting ring 5. Through the reverse rotation between the two, the direction of the centrifugal force of the reverse rotation forms an opposition with the direction of the chip splash, which can throw the turning wire and other chips into the arc-shaped inclined guide groove formed between multiple inclined flow blocks 901. Finally, with the continuous rotation of the slag-collecting ring 9, the turning wire and other chips will gather and collect along the guiding direction of the arc-shaped inclined guide groove, which plays the role of slag collection. This can reduce the probability of chips rebounding back to the cutting zone, reduce the risk of scratches and burrs on the surface during the turning of the drive shaft, and at the same time generate shearing force to quickly peel off the chips in the cutting zone. When the electric slider 401 drives the transmission shaft to rotate via the fixed block 603, the electric slider 401 will drive the internal gear ring 8 to rotate together via the shaft 402. When the internal gear ring 8 rotates, it will drive the gear 802 to rotate. Through the meshing of the teeth of the gear 802, when the gear 802 rotates, it will drive the external gear ring 801 to rotate in the opposite direction, thereby causing the external gear ring 801 to drive the slag-collecting ring 9 to rotate in the opposite direction to the transmission shaft, thus achieving the effect of driving the slag-collecting ring 9 to rotate in the opposite direction while the shaft rotates. When the drive shaft is placed, by pushing the two slag-blocking rings 1001 to move relative to each other, the two slag-blocking rings 1001 will squeeze the pressure spring 1002 within the grooved ring 10 and move, thereby opening the gap between the two slag-blocking rings 1001. When the drive shaft is placed inside the cylinder 1, by stopping the pushing of the two slag-blocking rings 1001, the two slag-blocking rings 1001 will return to their original position under the elastic push of the pressure spring 1002. The inner wall of the two slag-blocking rings 1001 will then fit against the outer wall of the drive shaft, thereby achieving a barrier between the machined part of the drive shaft and the inside of the cylinder 1, preventing the cutting chips generated during machining from splashing into the cylinder 1, and playing the role of blocking the cutting chips. When the turning chips are splashing, they are blocked by two slag-blocking rings 1001 and placed outside the two slag-blocking rings 1001. Combined with the shearing force generated by the rotation of the drive shaft and the counter-rotation between the slag-collecting ring 9, the turning chips will flow along the opening direction of the inclined arc slide 1003. The inclined arc slide 1003 replaces the hard obstruction of the traditional flat slag-blocking ring. The arc-shaped inclined structure guides the directional flow of chips, avoiding the chips from rebounding after hitting the slag-blocking ring and forming secondary splashing that scratches the machined surface of the drive shaft. At the same time, the static obstruction of the slag-blocking ring 1001 and the dynamic rotation collection of the slag-collecting ring 9 are seamlessly connected by the inclined arc slide 1003. The chips do not need to be scattered in a disorderly manner to enter the guide channel, improving the collection efficiency and avoiding the chips remaining in the gap between the two. When the two slag-blocking rings 1001 move relative to each other, the sliding shaft 1004 between the ends of the two slag-blocking rings 1001 will slide in the sliding groove 1005. The two slag-blocking rings 1001 will slide and fit together with the sliding shaft 1004 and the sliding groove 1005 to form a retractable ring structure. With the elastic push of the pressure spring 1002, the two slag-blocking rings 1001 will always form a complete slag-blocking ring, which will provide a sliding basis for the relative sliding between the two slag-blocking rings 1001. When the slag-gathering ring 9 gathers the turning chips through the inclined flow block 901, the gathered turning chips will move along the direction of the arc-shaped inclined guide groove opened between the multiple inclined flow blocks 901. The turning chips will flow and gather between the slag-gathering ring 9 and the groove ring 10. With the help of the inclined arc sliding mouth 1003 on the slag-blocking ring 1001 to block and guide the turning chips, the turning chips will finally be placed between the groove ring 10 and the slag-gathering ring 9, and finally fall into the slag storage box 7 along the slag flow chamber pipe 701 for collection and storage, thus playing the role of storing turning chips.
