Description

Technical Field

[0001] This invention relates to the field of transmission shaft processing technology, specifically to a processing device for transmission shaft components of railway locomotives. Background Technology

[0002] In the machining of transmission shaft components for railway locomotives, since the transmission shaft is partially exposed and partially concealed, in order to reduce costs, a first shaft (such as stainless steel, used for the exposed part) and a second shaft (such as carbon steel, used for the concealed part) made of different materials are usually combined together. However, when these two shaft parts are connected and cooled, the hardness of the cooled area increases, which will cause serious wear to the cutting tools during subsequent turning processes, affecting machining efficiency and machining quality.

[0003] A machining device for a transmission shaft is disclosed in publication number CN110202387B. The device includes a machining platform, a machining spindle, a mounting base, a motor, a positioning structure, a feeding structure, an ejection mechanism, a turning tool, and a discharge mechanism. The positioning structure is located on the machining platform and spaced apart in front of the machining spindle. It positions a second shaft to be machined so that the second shaft is coaxial with the first shaft to be machined. The ejection mechanism is located in front of the positioning structure and can move back and forth along the axial directions of the first and second shafts to be machined. It ejects the second shaft to be machined backward to make contact with the first shaft. The turning tool is located on the machining platform between the machining spindle and the positioning structure. After friction welding, the joint temperature of the shaft is high. The welding residue is directly removed by turning with the turning tool, avoiding the impact of heat changes on the accuracy of the shaft during cooling, thus improving the machining accuracy of the shaft. Furthermore, turning at a high temperature reduces the wear of the turning tool.

[0004] In the aforementioned application, the drive shaft is first welded and then turned. The two processing methods involve a certain waiting time, which results in low processing efficiency and an extended overall processing cycle, requiring improvement. Summary of the Invention

[0016] Working principle: The transmission shaft is first conveyed to the welding chuck and chuck 2 by the conveying device. The extension of cylinder 2 drives chuck 2 to move, causing chuck 2 and the welding chuck to respectively abut the two ends of the two transmission shafts. At this time, chuck 2 and the welding chuck clamp and fix the two transmission shafts. The motor drives the welding chuck to rotate through the gear mechanism, causing the opposite ends of the two transmission shafts to come into contact and rub against each other, thus fusing them together. During this process, cylinder 2 gradually extends, pushing the opposite ends of the two transmission shafts to fit tightly together. After welding is completed, the motor stops running and the welding... After the chuck opens, cylinder two retracts, causing the drive shaft to exit the welding chuck. Then, chuck two opens and the welded drive shaft is transported to the turning chuck via a conveying device. When cylinder three extends, it moves the turning chuck, allowing it to clamp one end of the welded drive shaft. During turning, the turning chuck moves the drive shaft laterally, allowing the turning tool to perform comprehensive turning operations on the welded part of the drive shaft, improving the turning range and effect. After turning is completed, cylinder three retracts and simultaneously opens the turning chuck, allowing the drive shaft to exit the turning chuck and be transported away.

[0017] This invention provides a processing device for railway locomotive driveshaft components. It has the following advantages:

[0018] 1. This invention involves sequentially conveying the drive shaft to be processed through a welding chuck and a turning chuck. While welding the drive shaft, the welded drive shaft can be turned simultaneously. Turning is performed at a relatively high friction welding temperature. Since the hardness of the shaft at the machining point is low, the wear of the turning tool is reduced. By performing welding and turning processes simultaneously, the processing waiting time can be reduced and the processing efficiency of the drive shaft can be improved.

[0019] 2. This invention uses a motor and gear mechanism to operate in coordination, so that the motor can synchronously drive two sets of transmission shafts to perform friction welding and rotary turning. The cylinder 2 drives the transmission shaft to be turned to move laterally, so that the turning tool can perform comprehensive turning operations on the welded part of the transmission shaft, thereby improving the turning range and effect.

[0020] 3. When the cylinder of the present invention extends, the bottom end of the upper housing abuts against the top end of the lower housing to form a closure, thereby intercepting the debris generated during welding and turning, and achieving the effect of collecting debris.

[0021] 4. When placing the drive shaft, the present invention places the drive shaft in the placement groove and passes it through the limiting member. The limiting member can limit the drive shaft, prevent the drive shaft from shaking during processing, and improve the stability of the drive shaft during processing. Attached Figure Description

[0033] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a processing device for a railway locomotive drive shaft component, comprising two parallel conveying devices 1. One conveying device 1 has a mounting base 2 fixedly connected to its outer frame. A motor 3 is fixedly mounted on the upper surface of the mounting base 2. Two sets of chucks 4 are provided on the side wall of the mounting base 2, each set consisting of a welding chuck 41 and a turning chuck 42. The motor 3 is connected to the two chucks 4 via a gear mechanism 5. The other conveying device 1 has a mounting base 6 fixedly connected to its outer frame. A cylinder 7 is fixedly connected to the surface of the mounting base 6. A chuck 8 is fixedly connected to the drive end of the cylinder 7. A top plate 9 is fixedly connected above the frames of both conveying devices 1. A cylinder 10 is fixedly connected to the upper surface of the top plate 9. A tool holder is fixedly connected to the drive end of the cylinder 10. A turning tool 11 is fixedly mounted inside the tool holder. Several clamps 12 for conveying the drive shaft are equidistantly fixed above the conveyor belt of the conveying device 1.

[0035] Specifically, two drive shafts made of different materials are placed on the clamps 12 of two conveying devices 1. The conveying devices 1 first convey the drive shafts to the welding chuck 41 and the second chuck 8. The second cylinder 10 extends and drives the second chuck 8 to move, so that the second chuck 8 and the welding chuck 41 respectively abut against the two ends of the two drive shafts. At this time, the two drive shafts are clamped and fixed by the second chuck 8 and the welding chuck 41. The motor 3 runs and drives the welding chuck 41 to rotate through the gear mechanism 5, so that the opposite ends of the two drive shafts come into contact and rub against each other, thus welding them together. During this process, the second cylinder 10 gradually extends and pushes the opposite ends of the two drive shafts to fit tightly together. After welding is completed, the motor 3 stops running and the welding chuck 41 opens. The second cylinder 10 retracts and drives the drive shafts out of the welding chuck 41, and then the second chuck 8 opens. The welded drive shafts are then transported by the conveying devices 1. After reaching the turning chuck 42, the new drive shaft to be processed is simultaneously transported to the welding chuck 41 and chuck 8. The welding drive shaft is clamped by the turning chuck 42, and then the motor 3 drives the drive shaft to rotate through the turning chuck 42. The cylinder 10 extends and brings out the turning tool 11 to descend and remove the weld at the welded joint of the drive shaft. After the removal is completed, the conveyor 1 transports the processed drive shaft away from the turning chuck 42. This application, by sequentially transporting the drive shaft to be processed through the welding chuck 41 and the turning chuck 42, allows for turning of the welded drive shaft while welding it. Turning is performed at a relatively high friction welding temperature. Since the hardness of the shaft processing area is low, the wear of the turning tool 11 is reduced. Compared with the prior art of welding first and then turning, the processing waiting time can be reduced and the processing efficiency of the drive shaft can be improved.

[0036] Please see the appendix Figure 4 The gear mechanism 5 includes a gear 51. A coupling is fixedly connected to the drive end of the motor 3. The other end of the coupling is rotatably connected to the mounting base 2. The gear 51 is fixedly mounted on the coupling. Gears 52 and 53 are meshed on both sides of the gear 51. Gear 52 is fixedly mounted on the outer wall of the shaft of the welding chuck 41. The shaft of the welding chuck 41 is rotatably connected to the mounting base 2. Gear 53 is slidably connected to the shaft of the turning chuck 42. An opening is provided on the surface of the mounting base 2 corresponding to the shaft of the turning chuck 42 for the shaft of the turning chuck 42 to pass through. A cylinder 13 is fixedly connected to the upper side wall of the mounting base 2. The cylinder 13 is rotatably connected to the shaft end of the turning chuck 42. A groove is provided on the surface of the shaft of the turning chuck 42. A protrusion is provided on the inner side wall of the gear 53 corresponding to the groove. Through the cooperation of the protrusion and the groove, the gear 53 drives the turning chuck 42 to rotate when it rotates.

[0037] Specifically, motor 3 drives gear 1 51 to rotate via coupling. Gear 1 51 drives gear 2 52 and gear 3 53 to rotate. Gear 2 52 drives welding chuck 41 to rotate. Welding chuck 41 drives the clamped drive shaft to rotate, and it cooperates with the drive shaft clamped by chuck 2 8 to perform friction welding. When gear 3 53 rotates, it drives turning chuck 42 to rotate. When cylinder 3 13 extends, it drives turning chuck 42 to move, so that turning chuck 42 can abut against one end of the welded drive shaft for clamping. During turning, it drives the drive shaft to move laterally, so that turning tool 11 can perform comprehensive turning operations on the welded part of the drive shaft, improving the turning range and effect. After turning is completed, cylinder 3 13 retracts and opens turning chuck 42, so that the drive shaft can be removed from turning chuck 42 and transported away.

[0038] Please see the appendix Figure 5 -Appendix Figure 6 A collecting assembly 14 is installed below the top plate 9. The collecting assembly 14 includes an upper housing 141 and a lower housing 142. The turning tool 11 passes through the upper housing 141. Semi-circular placement openings are respectively opened at opposite ends of the upper housing 141 and the lower housing 142. The diameter of the placement openings is the same as the diameter of the drive shaft. The bottom end of the lower housing 142 is fixedly connected to the inner frame of the two conveying devices 1. The top end of the upper housing 141 is rotatably connected to two sets of rotating brackets 143 via shafts. The two rotating brackets 143 are located at the cylinder two The top of the rotating bracket 143 is rotatably connected to the inner top wall of the top plate 9 via a shaft on both sides of the 10. The rotating bracket 143 consists of two plates that are rotatably connected vertically via a shaft. An elastic element 144 is fixedly connected to the outer wall of the lower plate. The elastic element in this application can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc. The top of the elastic element 144 is fixedly connected to the inner top wall of the top plate 9. The bottom of the lower housing 142 is provided with a discharge port for discharging debris. A collection box can be provided below the discharge port.

[0039] Specifically, an upward pulling force is applied to the rotating bracket 143 by the elastic element 144, causing the rotating bracket 143 to rotate and move closer together, thereby increasing the height of the upper housing 141 so that the bottom of the upper housing 141 is higher than the drive shaft.

[0040] Please see the appendix Figure 6 The collecting component 14 also includes a mounting ring 145, which is fixedly installed at the drive end of the cylinder 10. Vertical plates 146 are fixedly connected to both sides of the mounting ring 145, and the vertical plates 146 penetrate the top plate 9. Inclined blocks 147 are fixedly connected to the lower surface of the mounting ring 145 at the two vertical plates 146 respectively.

[0041] Specifically, when cylinder 2 10 extends, it causes the mounting ring 145 to descend, which in turn causes the vertical plates 146 on both sides of the mounting ring 145 to move downward. The inclined blocks 147 press against the rotating bracket 143, causing the rotating bracket 143 to rotate and extend, reducing the height of the upper housing 141. This allows the bottom of the upper housing 141 to abut against the top of the lower housing 142, forming a closure. This can intercept the debris generated during welding and machining, achieving the effect of collecting debris. After the vertical plates 146 descend and pass the pivot connection of the rotating bracket 143, the vertical plates 146 limit the rotating bracket 143, ensuring that the upper housing 141 is tightly pressed against the lower housing 142, preventing the upper housing 141 from accidentally opening and affecting its interception effect.

[0042] Please see the appendix Figure 7 The fixture 12 includes a base 121 and a placement platform 122. The upper surface of the placement platform 122 is provided with a U-shaped placement groove 123. A telescopic connecting rod 124 is fixedly connected to the upper surface of the base 121. The top end of the telescopic connecting rod 124 is fixedly connected to the lower surface of the placement platform 122. Limiting members 125 are provided on both sides of the placement groove 123 to limit the transmission rod inside the placement groove 123.

[0043] Specifically, the base 121 is used to connect the conveying device 1, the telescopic link 124 is used to connect the placement platform 122 and the base 121, so that the placement platform 122 can move up and down, the placement groove 123 is used to place the drive shaft, and the limiting member 125 is used to prevent the drive shaft in the placement groove 123 from shaking.

[0044] Example 2: Please refer to the appendix. Figure 7 Since the top of the lower housing 142 is higher than the drive shaft, it will cause motion interference. Therefore, this example provides the following structure: the surface of the telescopic link 124 is fitted with an elastic element 126.

[0045] Specifically, the elastic element 126 provides an upward elastic force to the placement platform 122, thereby increasing the distance between the base 121 and the placement platform 122. This makes the height of the drive shaft in the placement slot 123 higher than that of the lower housing 142, preventing the lower housing 142 from blocking the transmission of the drive shaft. When the transmission device 1 is processing the drive shaft, the drive shaft is sequentially transported to the two placement ports. When the cylinder 10 drives the upper housing 141 to descend, the drive shaft moves into the placement port of the upper housing 141. During subsequent descent, the drive shaft descends into the placement port of the lower housing 142, thus keeping the area to be processed of the drive shaft inside the upper housing 141 and the lower housing 142.

[0046] Example 3: Please refer to the appendix. Figure 8Since each fixture 12 requires an elastic element 126, the number of elastic elements 126 is increased, raising production and subsequent maintenance and replacement costs. Therefore, this example provides the following structure: A lifting assembly 15 is installed below the top plate 9. The lifting assembly 15 includes two fixed frames 151, which are respectively fixedly installed on the inner sidewalls of the two conveying devices 1. A lifting frame 152 is provided above the fixed frame 151. U-shaped connecting frames 153 are respectively fixedly connected to the lower surfaces of the two lifting frames 152. An elastic element 154 is sleeved on the surface of the connecting frame 153. The connecting frame 153 passes through the fixed frame 151. The two ends of the lifting frame 152 are bent downward to form a bending layer.

[0047] Specifically, an upward force is applied to the lifting frame 152 by the elastic element 154, thereby adjusting the height of the lifting frame 152 so that the height of the top surface of the lifting frame 152 is higher than the top of the lower housing 142. When the conveying device 1 conveys the drive shaft, the drive shaft will gradually increase in height as it passes through the bending layer, and drive the telescopic connecting rod 124 to extend, so that the drive shaft inside the fixture 12 is higher than the lower housing 142, avoiding the lower housing 142 from blocking the conveying of the drive shaft. When the cylinder 10 descends, a downward pressure is applied to the lifting frame 152, causing the lifting frame 152 and the drive shaft to descend, so that the upper housing 141 and the lower housing 142 cover the outside of the area to be processed by the drive shaft. With the above solution, it is not necessary to set an elastic element at each fixture 12 to increase the height of the drive shaft. The drive shaft can be lifted by the lifting assembly 15, thereby reducing the number of elastic elements required.

[0048] Example 4: Please refer to the appendix. Figure 7 The limiting component 125 adopts a bearing 1251, which is fixedly installed on the side wall of the placement groove 123. The inner diameter of the inner ring of the bearing 1251 is the same as the diameter of the drive shaft.

[0049] Specifically, when placing the drive shaft, the drive shaft is placed horizontally through the bearing 1251 into the placement groove 123. The bearing 1251 can limit the drive shaft and prevent it from shaking during processing.

[0050] Example 5: Please refer to the appendix. Figure 8 -Appendix Figure 10When the limiting member 125 uses a bearing 1251, it is necessary to move the transmission shaft laterally to place or remove the transmission shaft. The transmission shaft needs to be aligned and passed through the bearing 1251, which makes placement inconvenient and may burn workers when it is pulled out. Therefore, this embodiment provides the following structure: The limiting member 125 includes several sliding grooves 1252. The sliding grooves 1252 are opened on the inner side wall of the placement groove 123. The sliding grooves 1252 are slidably connected to the inside of the limiting block 1253. The inner side wall of the limiting block 1253 is fixedly connected to a pressing rod 1254. One end of the pressing rod 1254 away from the limiting block 1253 passes through the placement platform 122. The inner side wall of the limiting block 1253 is fixedly connected to an elastic member 1255. One end of the elastic member 1255 away from the limiting block 1253 is fixedly connected to the inner side wall of the sliding groove 1252.

[0051] Specifically, the elastic force of the elastic element 1255 applies a pulling force to the limiting block 1253, causing the limiting block 1253 to slide into the interior of the slide groove 1252, thereby opening the placement groove 123 to facilitate the vertical and rapid placement or removal of the drive shaft.

[0052] Please see the appendix Figure 8 -Appendix Figure 10 The placement platform 122 includes a connecting layer 1221. Two support layers 1222 are provided above the connecting layer 1221. A second sliding groove 1223 is provided on the upper surface of the connecting layer 1221. The bottom end of the support layer 1222 is slidably connected to the second sliding groove 1223. An elastic element 1225 is fixedly connected to the lower side wall of the support layer 1222. The end of the elastic element 1225 away from the support layer 1222 is fixedly installed on the inner side wall of the second sliding groove 1223. An inclined plate 1256 is provided at the end of the extrusion rod 1254 located outside the first sliding groove 1252. The bottom end of the inclined plate 1256 is fixedly installed on the upper surface of the connecting layer 1221. A push plate 16 is provided on the opposite side of the two support layers 1222. The top end of the push plate 16 is fixedly connected to the top plate 9 through a connecting column. The end of the push plate 16 facing the conveying direction of the clamp 12 is set as a triangle.

[0053] Specifically, elastic force is applied to the support layer 1222 by the elastic element 1225, causing the two support layers 1222 to slide closer together and the extrusion rod 1254 to be misaligned with the inclined plate 1256. At this time, the limiting block 1253 is housed inside the placement groove 123. When the clamp 12 passes through the top plate 9, the triangular end of the push plate 16 inserts into the two support layers 1222 and pushes the support layers 1222 to slide away from the push plate 16. When the support layers 1222 slide, they drive the extrusion rod 1254 to move, thus extruding... The rod 1254 moves along the inclined surface of the inclined plate 1256, causing the pressing rod 1254 to move into the interior of the slide groove 1252, thereby pushing the limiting block 1253 to slide outward to the upper surface of the drive shaft in the placement groove 123. This allows the limiting block 1253 to automatically limit the drive shaft during processing. When the push plate 16 and the support layer 1222 are misaligned, the limiting block 1253 automatically slides and is stored in the placement groove 123, achieving the effect of automatically sliding the limiting block 1253 to facilitate the removal of the drive shaft after placement.

[0054] Workflow: The transmission shaft is first conveyed to welding chuck 41 and chuck 8 by the conveying device 1. The extension of cylinder 210 drives chuck 28 to move, so that chuck 28 and welding chuck 41 respectively abut against the two ends of the two transmission shafts. At this time, chuck 28 and welding chuck 41 clamp and fix the two transmission shafts. The motor 3 runs and drives welding chuck 41 to rotate through gear mechanism 5, so that the opposite ends of the two transmission shafts come into contact and rub against each other, thus fusing them together. During this process, cylinder 210 gradually extends and pushes the opposite ends of the two transmission shafts to fit tightly together. After welding is completed, the motor 3 stops running and the welding chuck 41 stops moving. When chuck 41 opens, cylinder 2 10 retracts, causing the drive shaft to exit the welding chuck 41, and then chuck 2 8 opens. The welded drive shaft is then transported to the turning chuck 42 via the conveying device 1. When cylinder 3 13 extends, it drives the turning chuck 42 to move, so that the turning chuck 42 can clamp one end of the welded drive shaft. During turning, it drives the drive shaft to move laterally, allowing the turning tool 11 to perform comprehensive turning operations on the welded part of the drive shaft, improving the turning range and effect. After turning is completed, cylinder 3 13 retracts and simultaneously opens the turning chuck 42, allowing the drive shaft to exit the turning chuck 42 and be transported away.

[0055] When cylinder 2 10 extends, it causes the mounting ring 145 to descend, which in turn causes the vertical plates 146 on both sides of the mounting ring 145 to move downward. The inclined blocks 147 press against the rotating bracket 143, causing the rotating bracket 143 to rotate and extend, reducing the height of the upper housing 141. This allows the bottom of the upper housing 141 to abut against the top of the lower housing 142, forming a closed loop. This effectively intercepts debris generated during welding and machining, achieving the effect of collecting debris. After the vertical plates 146 descend and pass the pivot connection of the rotating bracket 143, the vertical plates 146 limit the rotation of the rotating bracket 143, ensuring that the upper housing 141 is tightly pressed against the lower housing 142, preventing the upper housing 141 from accidentally opening and affecting its interception effect.

[0056] Elastic force is applied to the support layer 1222 by the elastic element 1225, causing the two support layers 1222 to slide closer together and the extrusion rod 1254 to be misaligned with the inclined plate 1256. At this time, the limiting block 1253 is housed inside the placement groove 123. When the clamp 12 passes through the top plate 9, the triangular end of the push plate 16 inserts into the two support layers 1222 and pushes the support layers 1222 to slide away from the push plate 16. When the support layers 1222 slide, they drive the extrusion rod 1254 to move, causing the extrusion rod to move away from the push plate 16. 1254 moves along the inclined surface of the inclined plate 1256, causing the extrusion rod 1254 to move into the interior of the slide groove 1252, thereby pushing the limiting block 1253 to slide outward to the top of the drive shaft in the placement groove 123. This allows the limiting block 1253 to automatically limit the drive shaft during processing. When the push plate 16 and the support layer 1222 are misaligned, the limiting block 1253 automatically slides and is stored in the placement groove 123, achieving the effect of automatically sliding the limiting block 1253 to facilitate the placement and removal of the drive shaft.
