Description

Technical Field

[0001] The present invention relates to the technical field of turbochargers, and more particularly to a processing device for a turbine shaft of a turbocharger. Background Art

[0002] The turbine shaft is a key component in a turbocharger, connecting the turbine and compressor to transmit power. During turbocharger operation, the turbine shaft is subjected to the harsh operating environment of high temperature, high pressure, and high-speed rotation. Therefore, it requires high strength and wear resistance. Turbine shafts are typically made of high-quality alloy steel or stainless steel and undergo precision machining and heat treatment to ensure they meet the requirements of turbocharger operation. The design and structure of the turbine shaft are also optimized to increase its rigidity and stability, reduce vibration and noise, and thus enhance the performance and reliability of the turbocharger.

[0003] Patent document CN115625529A discloses a turbocharger turbine shaft machining device, which relates to the technical field of milling and grinding of shaft parts. The device comprises a horizontal base plate, on which are respectively provided a clamping and positioning assembly, a slot milling assembly, and a circular grinding assembly. The circular grinding assembly comprises a vertical support plate fixed to one side of the upper surface of the horizontal base plate, and two symmetrical adjustable telescopic cylinders fixed to the inner side wall near the upper end of the vertical support plate. The telescopic ends of the two adjustable telescopic cylinders are fixed to U-shaped mounting plates, and a circular grinding roller is rotatably mounted between the U-shaped mounting plates. A grinding drive motor is fixed to the side wall of each U-shaped mounting plate, and the output shaft end of the grinding drive motor passes horizontally through the U-shaped mounting plate and is coaxially fixed to the side end face of the circular grinding roller. The present invention solves the problems of conventional devices used for turbine shaft slot milling and grinding, such as insufficient clamping leading to large machining errors, low machining efficiency due to frequent disassembly and assembly, and inconvenient turbine shaft installation and adjustment.

[0004] During the machining process of a turbine shaft, it is usually necessary to install it inside a machining device and clamp it with a triangular clamp. However, existing turbine shaft machining devices mainly adopt a single-side one-end clamping method when milling and grinding it. For long shaft parts such as turbine shafts, single-side clamping can easily lead to insufficient clamping force. In particular, during the machining process of the turbine shaft, it is necessary to drive it to rotate around the axis. Insufficient clamping force not only easily causes the high-speed rotating turbine shaft to fall, posing a safety hazard, but also causes the turbine shaft to vibrate and deflect during machining, resulting in machining errors, thereby affecting the machining quality. Although the technical solution in publication number CN115625529A can effectively solve the problems of insufficient clamping, large processing errors, low efficiency due to frequent disassembly and assembly, inconvenient adjustment during processing, and inconvenient installation in traditional devices during turbine shaft milling and grinding, when disassembling the turbine shaft, its installation area and the processing area are in the same position, which means that the operator needs to reach into the processing area to operate during the disassembly process, which not only increases the safety risk, but may also cause the turbine shaft and the processing tool to be scratched due to improper operation during the disassembly and assembly process, causing damage to the outer wall of the turbine shaft, thereby affecting the processing accuracy and efficiency.

The outer walls of the four columnar cross-bars 237 are slidably connected to the inner walls of the elliptical grooves 239 provided in the four clamping block connecting blocks 238. The tops of the four elliptical grooves 239 are fixedly connected to the clamping blocks 2310. The bottoms of the left and right groups of clamping blocks 2310 are fixedly connected to the sides away from the clamping block connecting blocks 238. The outer walls of the left and right groups of clamping block rotating blocks 2312 are rotatably connected to the inner sides of the four groups of clamping block hinge blocks 2311. The bottom front side of the movable plate 21 is fixedly connected to the top of the T-shaped push plate 114. When the turbine shaft needs to be removed from the processing area for processing the outer wall, the hydraulic push rod 113 on the top of the T-shaped bottom plate 112 is started. The top end of the hydraulic push rod 113 pushes the T-shaped push plate 114 to move upward along the bottom of the inner side of the two L-shaped side plates 111. When the T-shaped push plate 114 moves upward, it drives the movable plate 21 to move upward synchronously. The movable plate 21 moves upward on the outer wall of the lifting rod 1237 through the two movable plate slides 22 provided. When the movable plate 21 moves downward, it pulls the lifting rod 1237 through the two lifting rod blocks 1238. When the movable plate 21 moves downward, the two lifting rods 1237 move upward, and the two lifting rods 1237 move upward and push the rotating plate 1231 to rotate ninety degrees on the inner side of the two hinged top blocks 12124 through the two bidirectional hinge blocks 1236. When the movable plate 21 moves toward the top, the top of the movable plate 21 pushes the four columnar push rods 233 to move toward the top. The four columnar push rods 233 move toward the top and push the two rectangular push blocks 235 to move upward on the inner side of the two sets of inverted T-shaped side plates 232. The upward movement of the two rectangular push blocks 235 brings The two sets of hinged vertical rods 236 are moved to the top, and then the columnar cross rods 237 on the inner sides of the two sets of hinged vertical rods 236 slide on the inner wall of the elliptical groove 239 opened in the clamping block connecting block 238, thereby pushing the two elliptical grooves 239 to rotate to clamp the turbine shaft fixed on the inner sides of the triangular clamping claws 12117 and the chuck 12111. At this time, the motor 1215 is reversely started to move the chuck 12111 and the triangular clamping claws 12117 outward and release the turbine shaft limit through the triangular clamping claws 12117. At this time, after the T-shaped push-pull rod 1233 is rotated, The included angle between the support plate 1234 and the T-type push-pull rod 1233 is just against the rear side of the movable plate 21, ensuring that the movable plate 21 is no longer affected by the two lifting vertical rod support blocks 1238 after movement, and falls due to gravity. At this time, the second hydraulic push rod 1239 can be started, and the second hydraulic push rod 1239 starts to pull the T-type push-pull rod 1233 to move forward. The T-type push-pull rod 1233 drives the turbine shaft to the rear side of the processing robot arm connecting frame 122. At this time, the turbine shaft clamped by the two sets of clamps 2310 can be taken out.

[0023] The working principle of the present invention is as follows: when the turbine shaft needs to be processed, first the gear 1216 clamps one end of the turbine shaft, and then the motor 1215 is started. The output end of the motor 1215 drives the gear 1216 to rotate. When the gear 1216 rotates, it engages with the inner sides of the two rack rods 1217, thereby driving the two rack rods 1217 to slide along the inner wall of the guide groove rod 1213. When the two rack rods 1217 slide, they drive the two expansion rods 1218 to expand and contract. At the same time, the H-shaped connecting plate 12113 rotating on the inner wall of the left collar 1219 and the second H-shaped connecting plate 12115 rotating on the inner wall of the right collar 1219 can respectively make the outer expansion column 12112 and the second outer expansion column 12113 expand and contract. 2114 rotates, and the outer expansion column 12112 and the second outer expansion column 12114 move inward, respectively driving the expansion column 12110 and the second expansion column 12116 to move inward, and then the two ends of the turbine shaft are clamped and fixed by the chuck 12111 and the triangular clamp 12117 to ensure the stability of the turbine shaft during the processing. Then, when the turbine shaft needs to be processed in a certain way, the workpiece is replaced by replacing one end of the robot arm body 1223, and then the second motor 12121 is started. The output end of the second motor 12121 drives the second transmission disc 12122 to rotate, and when the second transmission disc 12122 rotates, it drives the transmission disc 12119 through the crawler 12120. When the transmission disc 12119 rotates, it drives the transmission columnar rotating rod 12118 to rotate. When the transmission columnar rotating rod 12118 rotates, it drives the second outer expansion column 12114 to rotate. When the second outer expansion column 12114 rotates, it drives the second expansion column 12116 to rotate, and then drives the turbine shaft to rotate through the triangular clamp 12117. When the turbine shaft needs to be taken out of the processing area for processing the outer wall, the hydraulic push rod 113 on the top of the T-shaped bottom plate 112 is started. The top end of the hydraulic push rod 113 pushes the T-shaped push plate 114 to move upward along the bottom of the inner side of the two L-shaped side vertical plates 111. When the T-shaped push plate 114 moves upward, it drives the movable plate 21 to move upward synchronously. 21 moves upward on the outer wall of the lifting rod 1237 through the two movable plate slide grooves 22 provided. When the movable plate 21 moves downward, the two lifting rod blocks 1238 pull the lifting rod 1237 downward, and the two lifting rods 1237 move upward. The two lifting rods 1237 move upward and then push the rotating plate 1231 to rotate ninety degrees on the inner side of the two hinged top blocks 12124 through the two two-way hinge blocks 1236. When the movable plate 21 moves toward the top, the top of the movable plate 21 pushes the four columnar push rods 233 to move toward the top. The four columnar push rods 233 move toward the top and then push the two rectangular push blocks 235 to move upward on the inner side of the two sets of inverted T-shaped side plates 232.The upward movement of the two rectangular push blocks 235 drives the two sets of hinged vertical rods 236 to move toward the top, and then the columnar cross rods 237 on the inner sides of the two sets of hinged vertical rods 236 slide on the inner wall of the elliptical slide groove 239 opened in the clamping block connecting block 238, thereby pushing the two elliptical slide grooves 239 to rotate to clamp the turbine shaft fixed on the inner sides of the triangular clamping claws 12117 and the chuck 12111. At this time, the motor 1215 is reversed to start the chuck 12111 and the triangular clamping claws 12117 to move outward and release the turbine shaft limit through the triangular clamping claws 12117. At this time, the T-type push After the pull rod 1233 rotates, the included angle between the abutment plate 1234 and the T-shaped push-pull rod 1233 just touches the rear side of the movable plate 21, ensuring that the movable plate 21 is no longer affected by the two lifting rod abutment blocks 1238 after movement and falls due to gravity. At this time, the second hydraulic push rod 1239 can be activated, and the second hydraulic push rod 1239 starts to pull the T-shaped push-pull rod 1233 forward. The T-shaped push-pull rod 1233 drives the turbine shaft forward to the rear side of the processing robot arm connecting frame 122. At this time, the turbine shaft clamped by the two sets of clamping blocks 2310 can be removed.
