Description

Technical Field

[0001] This invention belongs to the field of machine tool technology, and specifically relates to a grinding machine tool for processing saddle castings. Background Technology

[0002] In the field of machinery, a saddle typically refers to a fixed base casting in large equipment used to support and guide moving parts in long-stroke linear motion. It is usually a core component of machine tool beds and large equipment bases, requiring extremely high flatness, straightness, parallelism, and surface finish. The saddle bears the weight of the equipment itself, the weight of the workpiece, and all the cutting forces during the machining process, and is the fundamental guarantee of the equipment's rigidity. The guide rails on it provide high-precision linear motion trajectories for the moving parts. The geometric accuracy of the machine tool depends primarily on the accuracy of the saddle guide rails.

[0003] Saddles are commonly manufactured using casting processes. One of the most crucial steps in machining saddle castings is grinding, as the grinding effect directly impacts the final quality of the saddle casting. Traditional grinding machines can meet the basic requirements for machining saddle castings. However, saddle castings require very high grinding precision, necessitating high-quality grinding on all surfaces. Traditional grinding machines typically require flipping the saddle casting after machining one surface before further processing. However, due to the generally heavy weight of saddle castings, this flipping process often necessitates methods such as hoisting. After flipping, calibration is required before proceeding to the next grinding step, significantly reducing processing efficiency and increasing the difficulty of the grinding process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a grinding machine tool for processing saddle castings. In the present invention, the clamping mechanism can clamp both ends of the workpiece to be processed, and then the bearing component descends. During the descent of the bearing component, the clamping mechanism drives the workpiece to be processed to flip, thereby realizing the automatic flipping of the workpiece. There is no need for hoisting and recalibration, which greatly improves the processing efficiency and accuracy stability, while reducing the difficulty of operation and safety risks.

[0005] The technical solution adopted to solve the above technical problems is: a grinding machine tool for processing saddle castings, including a grinding mechanism, a bearing assembly and a workpiece to be processed. The bearing assembly can support the workpiece to be processed. The grinding mechanism is located on the rear side of the bearing assembly and can grind the workpiece to be processed. Clamping mechanisms are provided on both sides of the bearing assembly. The clamping mechanisms can clamp the workpiece to be processed from both ends of the workpiece to be processed and can flip the workpiece to be processed. The supporting component can be raised and lowered, and the raising and lowering of the supporting component can drive the clamping mechanism to flip the workpiece to be processed.

[0006] With the above technical solution, the top of the bearing component supports the workpiece to be processed, and the grinding mechanism can then perform grinding on the workpiece. After one side is processed, the clamping mechanism can clamp both ends of the workpiece, and then the bearing component descends. During the descent, the bearing component drives the clamping mechanism to flip the workpiece. After the flip is completed, the bearing component rises again to support the middle of the workpiece, ensuring the support force of the workpiece and preventing deformation of the workpiece during grinding. At this time, the grinding mechanism can process the other side without the need for hoisting and recalibration, which greatly improves processing efficiency and accuracy stability, while reducing operation difficulty and safety risks.

[0007] Furthermore, the grinding mechanism includes a main unit, a base, a support frame, and a first hydraulic push rod. The main unit is horizontally slidably connected to the base from left to right, and the base is horizontally slidably connected to the support frame from front to back. A second hydraulic push rod is fixedly installed on the rear side of the support frame, with one end of the second hydraulic push rod fixedly connected to the rear side of the base. The first hydraulic push rod is fixedly installed on one side of the main unit, with one end of the first hydraulic push rod fixedly connected to the main unit. A grinding head is vertically slidably connected to the main unit.

[0008] With the above technical solution, the main unit is horizontally slidably connected to the base, and the base is horizontally slidably connected to the support frame. A second hydraulic push rod is fixedly installed on the rear side of the support frame, with one end of the second hydraulic push rod fixedly connected to the rear side of the base. A first hydraulic push rod is fixedly installed on one side of the main unit, with one end of the first hydraulic push rod fixedly connected to the main unit. A grinding head is vertically slidably connected to the main unit. This allows the first hydraulic push rod to push the main unit to slide horizontally left and right on the base, the second hydraulic push rod to push the base to slide horizontally back and forth, and the grinding head to slide vertically on the main unit. This enables the grinding head to move precisely in three-dimensional space, adapting to grinding requirements at different positions and angles, thereby ensuring the machining accuracy and surface quality of each surface of the saddle casting.

[0009] Furthermore, the clamping mechanism comprises two sets, symmetrically arranged on both sides of the bearing assembly. Each clamping mechanism includes a clamping ring, a main frame, a transmission ring, transmission teeth, a transmission rod, and a third hydraulic push rod. Tracks are symmetrically fixedly connected to both sides of the bearing assembly. The main frame is horizontally slidably connected to the tracks. The clamping ring is rotatably connected to the main frame. The transmission ring is rotatably connected to the clamping ring. The transmission teeth are rotatably connected to the clamping ring. The transmission rod is vertically slidably connected to the front side of the main frame. The third hydraulic push rod is fixedly arranged at one end of the track, and one end of the third hydraulic push rod is fixedly connected to the main frame.

[0010] With the above technical solution, since the bearing components are symmetrically fixedly connected to the rails on both sides, the main frame is horizontally slidably connected to the rails, the clamping ring is rotatably connected to the main frame, the transmission ring is rotatably connected to the clamping ring, the transmission gear is rotatably connected to the clamping ring, the transmission rod is vertically slidably connected to the front side of the main frame, and the third hydraulic push rod is fixedly set at one end of the rail. One end of the third hydraulic push rod is fixedly connected to the main frame, so that the third hydraulic push rod can drive the main frame to slide horizontally left and right on the rail, that is, drive the clamping mechanism to slide horizontally left and right, thereby adapting to workpieces of different lengths to be processed. At the same time, the two clamping mechanisms can also move closer to each other, exposing both ends of the workpiece to be processed, so that the grinding head can perform grinding processing on both ends of the workpiece to be processed.

[0011] Furthermore, a crossbeam is fixedly installed inside the clamping ring, vertical rails are symmetrically fixedly installed on both sides of the crossbeam, clamping plates are vertically slidably connected to the vertical rails, longitudinal adjusting rods are symmetrically rotatably connected to the crossbeam, and transverse adjusting rods are symmetrically threaded to both sides of the clamping ring.

[0012] With the above technical solution, since a crossbeam is fixedly installed inside the clamping ring, vertical rails are symmetrically fixedly installed on both sides of the crossbeam, clamping plates are vertically slidably connected to the vertical rails, longitudinal adjusting rods are symmetrically rotatably connected to the crossbeam, and transverse adjusting rods are symmetrically threaded on both sides of the clamping ring, the clamping plates and the crossbeam can clamp both ends of the workpiece to be processed, making it convenient for the clamping ring to rotate and flip the workpiece to be processed.

[0013] Furthermore, the clamping plate is vertically slidably connected between the two vertical rails, the longitudinal adjusting rod passes through the clamping plate, the longitudinal adjusting rod is threadedly connected to the clamping plate, and one end of the transverse adjusting rod is rotatably connected to a ball bearing.

[0014] With the above technical solution, the clamping plate is vertically slidably connected between two vertical rails. The longitudinal adjusting rod passes through the clamping plate and is threadedly connected to it. One end of the transverse adjusting rod is rotatably connected to a ball bearing. This allows the longitudinal adjusting rod to rotate, causing the clamping plate to move up and down along the vertical rails, thereby adjusting the clamping height of the workpiece to be processed to accommodate workpieces of different heights. The rotation of the transverse adjusting rod can adjust the length of the transverse adjusting rod extending into the clamping ring. The end of the transverse adjusting rod with the ball bearing can contact the side of the workpiece to be processed, allowing the two transverse adjusting rods to clamp the workpiece from the longitudinal direction. The length of the transverse adjusting rod extending into the clamping ring is adjustable to accommodate workpieces of different widths. The ball bearing facilitates adjustment by rotating the transverse adjusting rod and prevents slippage when the workpiece is flipped, effectively improving the grinding accuracy.

[0015] Furthermore, a fixing plate is fixedly provided on the clamping ring, and a limiting groove is provided on the fixing plate. The transmission teeth are rotatably connected in the limiting groove. A helical gear ring is provided on the inner side of the transmission ring, and an outer gear ring is provided on the outer side of the transmission ring. The transmission teeth and the helical gear ring mesh in one direction.

[0016] With the above technical solution, a fixed plate is fixedly installed on the clamping ring, and a limiting groove is provided on the fixed plate. The transmission teeth are rotatably connected in the limiting groove. A helical tooth ring is provided on the inner side of the transmission ring, and an outer tooth ring is provided on the outer side of the transmission ring. The transmission teeth and the helical tooth ring mesh in one direction, so that the transmission teeth can only rotate a limited angle in the limiting groove. A torsion spring is provided at the rotatable connection between the transmission teeth and the limiting groove to achieve one-way meshing between the transmission teeth and the helical tooth ring. When the transmission ring rotates forward, the transmission teeth mesh with the helical tooth ring, so that the forward rotation of the transmission ring drives the clamping ring to rotate forward. When the transmission ring rotates in reverse, the transmission teeth do not mesh with the helical tooth ring, so that the reverse rotation of the transmission ring does not drive the clamping ring to rotate.

[0017] Furthermore, the load-bearing assembly includes a load-bearing plate, a hydraulic lifting rod, and a transmission rod. The hydraulic lifting rod is fixedly installed on the ground, the load-bearing plate is fixedly installed at the top of the hydraulic lifting rod, and the transmission rod is fixedly connected to the front side of the load-bearing plate.

[0018] With the above technical solution, since the hydraulic lifting rod is fixedly installed on the ground, the bearing plate is fixedly installed at the top of the hydraulic lifting rod, and the transmission rod is fixedly connected to the front side of the bearing plate, the lifting of the hydraulic lifting rod can drive the bearing plate to lift, and the lifting of the bearing plate can drive the transmission rod to lift.

[0019] Furthermore, the transmission rod extends through both ends of the transmission rod, and the transmission rod is horizontally slidably connected to the transmission rod. A drive rack is provided at the top of the transmission rod, and the drive rack meshes with the external gear ring.

[0020] Through the above technical solution, since the transmission rod passes through both ends of the transmission rod and the transmission rod slides horizontally with the transmission rod, and the top of the transmission rod is provided with a drive rack, which meshes with the outer gear ring, the horizontal sliding of the main frame on the track can drive the transmission rod to slide horizontally left and right. The setting of the transmission rod does not hinder the horizontal sliding of the transmission rod. The vertical lifting of the bearing plate can drive the vertical lifting of the transmission rod, which in turn can drive the transmission rod to lift vertically. The vertical lifting of the transmission rod can drive the drive rack to lift vertically, which in turn can drive the outer gear ring to rotate, that is, drive the transmission ring to rotate. The vertical descent of the bearing plate causes the transmission rod to descend vertically, which in turn causes the transmission rod to descend vertically. The vertical descent of the transmission rod causes the drive rack to descend vertically, which in turn causes the outer gear ring to rotate forward, i.e., causes the transmission ring to rotate forward. The vertical descent of the bearing plate causes the transmission rod to rise vertically, which in turn causes the transmission rod to rise vertically. The vertical descent of the transmission rod causes the drive rack to rise vertically, which in turn causes the outer gear ring to rotate in reverse, i.e., causes the transmission ring to rotate in reverse.

[0021] Furthermore, the top of the support plate is provided with an clearance groove, and a support rod is fixedly connected to the front side of the base, the support rod being able to pass through the clearance groove.

[0022] With the above technical solution, since the top of the support plate is provided with an clearance groove and the front of the base is fixedly connected with a support rod, the support rod can pass through the clearance groove, allowing it to support the workpiece to be processed. The horizontal sliding of the base drives the support rod to slide horizontally back and forth, and the support rod can transport the workpiece to be processed to the top of the support plate through the clearance groove. The hydraulic lifting rod drives the support plate to rise, and the support plate supports the workpiece to be processed, thus realizing the loading of the workpiece to be processed. The workpiece to be processed can be placed on the support plate without hoisting, which not only facilitates subsequent processing operations, but also provides a stable and impact-free loading method, reducing safety risks during the loading process.

[0023] Furthermore, the front end of the bearing rod is provided with a receiving groove, and a limiting plate is rotatably connected inside the receiving groove.

[0024] With the above technical solution, since the front end of the bearing rod is provided with a receiving groove, and a limiting plate is rotatably connected in the receiving groove, the limiting plate can be erected to prevent the workpiece to be processed from accidentally slipping when the bearing rod is feeding it. At the same time, when the limiting plate is erected, the base can slide forward after processing, which will drive the erected limiting plate to slide forward and push the processed workpiece off the bearing plate, thus realizing the unloading of the workpiece.

[0025] The beneficial effects of this invention are as follows: (1) In this invention, the clamping mechanism can clamp both ends of the workpiece to be processed, and then the bearing component descends. During the descent of the bearing component, the clamping mechanism flips the workpiece to be processed. After the flip is completed, the bearing component rises again to support the middle of the workpiece to be processed, ensuring the support force of the workpiece to be processed and preventing deformation of the workpiece to be processed during grinding. At this time, the grinding mechanism can process the other side without hoisting and recalibration, which greatly improves the processing efficiency and accuracy stability, while reducing the difficulty of operation and safety risks. (2) In this invention, the limiting plate can be erected to prevent the workpiece from accidentally slipping when the bearing rod is feeding the workpiece. At the same time, the limiting plate can also be erected so that after the processing is completed, the base slides forward, which drives the erected limiting plate to slide forward, pushing the processed workpiece off the bearing plate and realizing the unloading of the workpiece. The entire loading and unloading process is stable and impact-free, effectively avoiding damage to the workpiece and effectively improving the automation level of the production line.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] like Figure 1 As shown, a grinding machine tool for processing saddle castings includes a grinding mechanism 1, a support component 3, and a workpiece 4 to be processed. The support component 3 can support the workpiece 4 to be processed. The grinding mechanism 1 is located on the rear side of the support component 3 and can grind the workpiece 4 to be processed. Clamping mechanisms 2 are provided on both sides of the support component 3. The clamping mechanisms 2 can clamp the workpiece 4 to be processed from both ends and can flip the workpiece 4 to be processed. The support component 3 can be raised and lowered, and the raising and lowering of the support component 3 can drive the clamping mechanism 2 to flip the workpiece 4 to be processed.

[0030] In this embodiment, the top of the bearing component 3 supports the workpiece 4 to be processed, and the grinding mechanism 1 can then perform grinding on the workpiece 4. After one side is processed, the clamping mechanism 2 can clamp both ends of the workpiece 4. Then the bearing component 3 descends, and during the descent, the bearing component 3 drives the clamping mechanism 2 to flip the workpiece 4. After the flip is completed, the bearing component 3 rises again to support the middle of the workpiece 4, ensuring the support force of the workpiece 4 and preventing deformation of the workpiece 4 during grinding. At this time, the grinding mechanism 1 can process the other side without hoisting and recalibration, which greatly improves processing efficiency and accuracy stability, while reducing operation difficulty and safety risks.

[0031] like Figure 2As shown, the grinding mechanism 1 includes a main unit 11, a base 12, a support frame 13, and a first hydraulic push rod 14. The main unit 11 is horizontally slidably connected to the base 12, and the base 12 is horizontally slidably connected to the support frame 13. A second hydraulic push rod 131 is fixedly installed on the rear side of the support frame 13. One end of the second hydraulic push rod 131 is fixedly connected to the rear side of the base 12. The first hydraulic push rod 14 is fixedly installed on one side of the main unit 11. One end of the first hydraulic push rod 14 is fixedly connected to the main unit 11. A grinding head 111 is vertically slidably connected to the main unit 11.

[0032] In this embodiment, the first hydraulic push rod 14 can push the main unit 11 to slide horizontally left and right on the base 12, the second hydraulic push rod 131 can push the base 12 to slide horizontally back and forth, and the grinding head 111 can slide vertically on the main unit 11, so that the grinding head 111 can move precisely in three-dimensional space to adapt to the grinding requirements of different positions and angles, thereby ensuring the processing accuracy and surface quality of each surface of the saddle casting.

[0033] like Figure 3 - Figure 6 As shown, there are two sets of clamping mechanisms 2, which are symmetrically arranged on both sides of the bearing assembly 3. The clamping mechanism 2 includes a clamping ring 21, a main frame 22, a transmission ring 23, a transmission tooth 24, a transmission rod 25, and a third hydraulic push rod 26. Tracks 261 are symmetrically fixedly connected to both sides of the bearing assembly 3. The main frame 22 is horizontally slidably connected to the track 261. The clamping ring 21 is rotatably connected to the main frame 22. The transmission ring 23 is rotatably connected to the clamping ring 21. The transmission tooth 24 is rotatably connected to the clamping ring 21. The transmission rod 25 is vertically slidably connected to the front side of the main frame 22. The third hydraulic push rod 26 is fixedly arranged at one end of the track 261, and one end of the third hydraulic push rod 26 is fixedly connected to the main frame 22. A crossbeam 215 is fixedly installed inside the clamping ring 21. Vertical rails 214 are symmetrically fixedly installed on both sides of the crossbeam 215. A clamping plate 211 is vertically slidably connected to the vertical rails 214. A longitudinal adjusting rod 212 is symmetrically rotatably connected to the crossbeam 215. A transverse adjusting rod 213 is symmetrically threaded on both sides of the clamping ring 21. The clamping plate 211 is vertically slidably connected between two vertical rails 214. The longitudinal adjusting rod 212 passes through the clamping plate 211 and is threadedly connected to the clamping plate 211. One end of the transverse adjusting rod 213 is rotatably connected to a ball bearing 2131.

[0034] In this embodiment, when the longitudinal adjusting rod 212 rotates, it can drive the clamping plate 211 to move up and down along the vertical rail 214, thereby adjusting the clamping height of the clamping plate 211 on the workpiece 4 to be processed, so as to adapt to workpieces 4 of different heights. The rotation of the transverse adjusting rod 213 can adjust the length of the transverse adjusting rod 213 extending into the clamping ring 21. One end of the transverse adjusting rod 213 with the ball 2131 can contact the side of the workpiece 4 to be processed, so that the two transverse adjusting rods 213 can clamp the workpiece 4 to be processed from the longitudinal direction. The length of the transverse adjusting rod 213 extending into the clamping ring 21 is adjustable to adapt to workpieces 4 of different widths. The ball 2131 is set to facilitate the adjustment by rotating the transverse adjusting rod 213. The transverse adjusting rod 213 is set to prevent the workpiece 4 to be processed from sliding when it is flipped, effectively improving the grinding accuracy. The third hydraulic push rod 26 can drive the main frame 22 to slide horizontally left and right on the track 261, that is, drive the clamping mechanism 2 to slide horizontally left and right, so as to adapt to workpieces 4 of different lengths. At the same time, the two clamping mechanisms 2 can also move closer to each other, exposing the two ends of the workpiece 4 to be processed, so that the grinding head 111 can perform grinding processing on the two ends of the workpiece 4.

[0035] like Figure 7 - Figure 11 As shown, a fixing plate 216 is fixedly provided on the clamping ring 21, and a limiting groove 217 is provided on the fixing plate 216. The transmission gear 24 is rotatably connected in the limiting groove 217. A helical gear ring 231 is provided on the inner side of the transmission ring 23, and an outer gear ring 232 is provided on the outer side of the transmission ring 23. The transmission gear 24 and the helical gear ring 231 mesh in one direction. The load-bearing component 3 includes a load-bearing plate 31, a hydraulic lifting rod 32, and a transmission rod 33. The hydraulic lifting rod 32 is fixedly installed on the ground, the load-bearing plate 31 is fixedly installed at the top of the hydraulic lifting rod 32, and the transmission rod 33 is fixedly connected to the front side of the load-bearing plate 31. The transmission rod 33 has two ends that pass through the transmission rod 25. The transmission rod 25 and the transmission rod 33 are horizontally slidably connected. The top of the transmission rod 25 is provided with a drive rack 251, which meshes with the outer gear ring 232.

[0036] In this embodiment, the lifting of the hydraulic lifting rod 32 can drive the lifting of the bearing plate 31, the lifting of the bearing plate 31 can drive the lifting of the transmission rod 33, the vertical lifting of the transmission rod 33 can drive the vertical lifting of the transmission rod 25, the vertical lifting of the transmission rod 25 can drive the vertical lifting of the drive rack 251, and the vertical lifting of the drive rack 251 can drive the rotation of the outer gear ring 232, that is, drive the rotation of the transmission ring 23. The vertical descent of the bearing plate 31 can drive the transmission rod 33 to descend vertically, which in turn drives the transmission rod 25 to descend vertically. The vertical descent of the transmission rod 33 can drive the drive rack 251 to descend vertically, which in turn drives the outer gear ring 232 to rotate forward, i.e., drives the transmission ring 23 to rotate forward. The vertical descent of the bearing plate 31 can drive the transmission rod 33 to rise vertically, which in turn drives the transmission rod 25 to rise vertically. The vertical descent of the transmission rod 25 can drive the drive rack 251 to rise vertically, which in turn drives the outer gear ring 232 to rotate in reverse, i.e., drives the transmission ring 23 to rotate in reverse. When the transmission ring 23 rotates forward, the transmission teeth 24 mesh with the helical gear ring 231, so that the transmission ring 23 rotates forward and drives the clamping ring 21 to rotate forward. When the transmission ring 23 rotates in reverse, the transmission teeth 24 do not mesh with the helical gear ring 231, so that the transmission ring 23 does not drive the clamping ring 21 to rotate in reverse. Ultimately, when the support plate 31 descends vertically, it can drive the clamping ring 21 to rotate, thereby flipping the workpiece 4 to be processed. When the support plate 31 rises vertically, it does not drive the clamping ring 21 to rotate, thus maintaining the angle of the workpiece 4 to be processed.

[0037] like Figure 1 - Figure 2 as well as Figure 12 As shown, the top of the bearing plate 31 is provided with a relief groove 311, and the front side of the base 12 is fixedly connected with a bearing rod 121, which can pass through the relief groove 311. The front end of the support rod 121 is provided with a receiving groove 1211, and a limit plate 122 is rotatably connected inside the receiving groove 1211.

[0038] In this embodiment, the support rod 121 can support the workpiece 4 to be processed. The support rod 121 can slide horizontally back and forth through the base 12. The support rod 121 can transport the workpiece 4 to be processed to the top of the support plate 31 through the clearance groove 311. The hydraulic lifting rod 32 drives the support plate 31 to rise. The support plate 31 supports the workpiece 4 to be processed, thus realizing the loading of the workpiece 4. The workpiece 4 to be processed can be placed on the support plate 31 without hoisting. This not only facilitates subsequent processing operations, but also makes the loading method stable and impact-free, reducing the safety risks in the loading process. The limiting plate 122 can be erected to prevent the workpiece 4 from accidentally slipping when the bearing rod 121 is feeding it. At the same time, the limiting plate 122 can also be erected so that after processing is completed, the base 12 slides forward, which drives the erected limiting plate 122 to slide forward, pushing the processed workpiece 4 off the bearing plate 31, thus realizing the unloading of the workpiece 4.

[0039] Working principle: During operation, the second hydraulic push rod 131 can push the base 12 to slide horizontally forward, allowing the bearing rod 121 at the front end of the base 12 to pass through the clearance groove 311 on the bearing plate 31, placing the workpiece 4 to be processed on the bearing rod 121. Then, the second hydraulic push rod 131 drives the base 12 to slide horizontally backward, so that the bearing rod 121 sends the workpiece 4 to be processed directly above the bearing plate 31. The hydraulic lifting rod 32 starts to drive the bearing plate 31 to rise vertically. The upper surface of the bearing plate 31 contacts and supports the workpiece 4 to be processed, completing the loading. During this process, the limiting plate 122 can be erected to prevent the workpiece 4 to be processed from accidentally slipping when the bearing rod 121 carries the workpiece 4 to be processed. After the loading is completed, the limiting plate 122 is reset. Then, the first hydraulic push rod 14 pushes the main unit 11 to slide horizontally left and right on the base 12, the second hydraulic push rod 131 pushes the base 12 to slide horizontally back and forth, and the grinding head 111 slides vertically on the main unit 11, so that the grinding head 111 can move precisely in three-dimensional space, thereby realizing the full grinding process of the workpiece 4 to be processed by the grinding head 111. The third hydraulic push rod 26 can drive the main frame 22 to slide horizontally left and right on the track 261, that is, drive the clamping mechanism 2 to slide horizontally left and right, so that both ends of the workpiece 4 to be processed enter the clamping ring 21. Then, rotate the longitudinal adjusting rod 212. When the longitudinal adjusting rod 212 rotates, it can drive the clamping plate 211 to move up and down along the vertical rail 214, thereby driving the clamping plate 211 to cooperate with the crossbeam 215 to clamp the workpiece 4 to be processed. Rotate the transverse adjusting rod 213 so that the end of the transverse adjusting rod 213 equipped with the ball 2131 can contact the side of the workpiece 4 to be processed, so that the two transverse adjusting rods 213 can clamp the workpiece 4 to be processed from the longitudinal direction. The clamping mechanism 2 completes the clamping of the workpiece 4 to be processed. Cooperating with the bearing plate 31, it ensures that the workpiece 4 to be processed maintains a stable posture during the grinding process and effectively prevents the position displacement caused by processing vibration. The two clamping mechanisms 2 can be brought closer to each other and moved towards the center, exposing both ends of the workpiece 4 to be processed. The grinding head 111 can then grind both ends of the workpiece 4. After the workpiece 4 is processed, the two clamping mechanisms 2 can slide back to their original positions on both sides. When the workpiece 4 needs to be flipped, the hydraulic lifting rod 32 drives the bearing plate 31 to descend vertically. The vertical descent of the bearing plate 31 drives the transmission rod 33 to descend vertically. The vertical descent of the transmission rod 33 drives the transmission rod 25 to descend vertically. The vertical descent of the transmission rod 25 drives the drive rack 251 to descend vertically. The vertical descent of the drive rack 251 drives the outer gear ring 232 to rotate clockwise, that is, drives the transmission ring 23 to rotate clockwise. When the transmission ring 23 rotates clockwise, the transmission teeth 24 mesh with the helical gear ring 231, realizing that the clockwise rotation of the transmission ring 23 drives the clamping ring 21 to rotate clockwise, that is, the workpiece 4 is flipped. After the workpiece 4 is flipped, the hydraulic lifting rod 32 is restarted, driving the bearing plate 31 to rise vertically. The vertical rise of the bearing plate 31 can drive the transmission rod 33 to rise vertically, which in turn can drive the transmission rod 25 to rise vertically. The vertical rise of the transmission rod 25 can drive the drive rack 251 to rise vertically, which in turn can drive the outer gear ring 232 to reverse, i.e., drive the transmission ring 23 to reverse. When the transmission ring 23 reverses, the transmission teeth 24 do not mesh with the helical gear ring 231, so that the transmission ring 23 does not drive the clamping ring 21 to rotate when it reverses. At this time, the workpiece 4 is stably maintained in the flipped position, so that the bearing plate 31 can rise and reset to continue supporting the workpiece 4, creating favorable conditions for subsequent processing steps. After the workpiece 4 is ground, the second hydraulic push rod 131 pushes the base 12 to slide forward, which in turn drives the vertical limit plate 122 to slide forward, pushing the finished workpiece 4 off the bearing plate 31, thus unloading the workpiece 4. The entire loading and unloading process is stable, effectively avoiding damage to the workpiece 4 and improving the automation level of the production line.
