Description

Technical Field

[0001] This invention relates to the field of grinding and polishing equipment, and in particular to a cutting and grinding device suitable for a variety of castings with large errors. Background Technology

[0002] In high-end manufacturing and specialty casting fields such as heavy equipment, rail transportation, shipbuilding, and large-scale art casting, large castings (such as engine cylinder blocks for heavy equipment, bogie frame castings for rail transportation, engine bases and cabin valve bodies for ships, and core components of large-scale art sculptures) are core structural components that determine the performance, safety, and service life of the entire equipment. Their processing quality directly affects the reliability and stability of the end product. These castings generally have the following characteristics: many varieties and small batches; production mode tends to be customized and flexible; large blank allowance and large error: due to casting process limitations, the blank size and shape differ significantly from the theoretical model, and defects such as flash, riser residue, and misalignment are randomly located; the process relies on highly skilled workers, and the subsequent cutting (removing risers and flash) and grinding (smoothing welds and grinding surfaces) processes highly depend on the workers' experience and feel, involving repeated "measurement-cutting / grinding" operations.

[0003] Currently, the cutting and grinding equipment for this type of large casting has a fixed clamping and support structure on the worktable, which cannot flexibly adjust the distance between the two sets of clamping and support components. Moreover, the width of the clamping and support components themselves is not adjustable, which can only adapt to the clamping and placement of a single or a few types of castings. It has poor versatility and flexibility, and it is difficult to meet the diverse clamping and processing needs of multiple types of castings. The scope of application of the equipment is limited. At the same time, during the casting cutting and grinding process, the angle of the casting is fixed and cannot be flexibly adjusted, making it difficult to achieve all-round processing of all parts of the casting. It is easy to generate processing dead corners, and it is necessary to repeatedly disassemble and adjust the clamping position. This not only increases the process time and reduces the processing efficiency, but also easily causes positioning deviation due to multiple clamping, affecting the processing quality of the casting. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing casting clamping structure being fixed and having a limited scope of application, and to provide a cutting and grinding device suitable for a variety of castings with large errors.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: This invention provides a cutting and grinding device suitable for various types of castings with large errors, including a conveying unit, a cutting and grinding unit, a worktable, a scanning and guiding unit, and an auxiliary control unit. The workbench includes two processing stations, which are arranged adjacent to each other. Each processing station includes a support base, and two left and right distributed support side plates are detachably connected to the top of the support base. A mounting frame is provided between the two support side plates. The two support side plates and the mounting frame are connected by an AC rotating component, which causes the mounting frame to rotate around the X-axis and Z-axis respectively. The mounting frame is provided with two symmetrical clamping support components on the left and right. The width of the clamping support components is adaptively adjusted according to the size of the casting. The two clamping support components are respectively connected to a synchronous adjustment component, which is used to synchronously adjust the position of the two clamping support components.

[0006] In this technical solution, the positions of the two clamping support components are adjusted synchronously by a synchronous adjustment component, so that the distance between the two clamping support components can be adjusted and controlled. This allows the clamping support components on both sides to clamp and place castings of different sizes, increasing the flexibility of the worktable and making it suitable for various types of castings. Furthermore, the width of the clamping support components can be adaptively adjusted according to the size of the casting, further expanding the applicability of the worktable.

[0007] Preferably, the AC rotating component includes an A-axis rotating assembly and a C-axis rotating assembly. The two ends of the A-axis rotating assembly are rotatably connected to the supporting side plates on both sides, respectively. The output end of the A-axis rotating assembly is connected to the C-axis rotating assembly, and the output end of the C-axis rotating assembly is connected to the mounting frame.

[0014] In this technical solution, the casting can be supported from the bottom by the central support component, which increases the stability of the casting during processing.

[0015] Preferably, the clamping support component includes a central frame and side clamping plates, with side clamping plates provided on both sides of the central frame, and the side clamping plates on both sides moving synchronously through an extension and retraction assembly; The bottom of the central frame is connected to the output actuator of the synchronous adjustment component.

[0016] In this technical solution, the positions of the two side clamp support plates are adjusted synchronously by the extension and retraction components.

[0017] Furthermore, the unfolding and retracting assembly includes a central moving rack, on both the upper and lower sides of the central moving rack are meshed with rotating gears, and on the opposite sides of the two rotating gears are meshed with side moving racks. The opposite ends of the rotating gear and the side moving rack are slidably connected to the side of the central frame shell. The ends of the rotating gear away from the rotating gear and the side moving rack away from the central frame shell are respectively connected to the side of the two side clamping plates near the central frame shell.

[0018] In this technical solution, the central moving rack and the side moving rack move synchronously towards or away from each other, adjusting the positions of the two side clamping plates respectively, so that the side clamping plates on both sides can move synchronously towards or away from each other.

[0019] Furthermore, a connecting post is connected to one side of the central moving rack, and the surface of the connecting post is slidably connected to one side of the central frame shell. A push-pull plate is connected to the end of the connecting post away from the central moving rack. One side of the push-pull plate is connected to the output end of the linear telescopic device, which is installed on the outside of the middle frame.

At the same time, the handling unit and the cutting and grinding unit work together in two-stage continuous processing to achieve seamless connection between casting handling, flipping, clamping, and grinding operations. Furthermore, the scanning of new workpieces is completed simultaneously during the second processing stage, improving work efficiency. Moreover, the linkage and automated closed-loop control of each process integrates manual loading triggering, automatic door linkage, casting clamping, processing inspection, and unloading and conveying, constructing a continuous processing closed loop without human intervention, ensuring the stability and continuity of the processing flow. Furthermore, the positions of the two clamping support components are adjusted synchronously by the synchronous adjustment component, so that the distance between the two clamping support components can be adjusted and controlled.

[0044] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0045] Figures 1 to 17 The diagram shown is a structural schematic of an embodiment of the cutting and grinding device of the present invention applicable to castings with large errors of various types.

[0046] A cutting and grinding device suitable for various types of castings with large errors includes a conveying unit, a cutting and grinding unit, a worktable, a scanning and guiding unit, and an auxiliary control unit. The conveying unit is used to transport the castings, realize the transfer, flipping, and loading and unloading of the castings. The cutting and grinding unit cuts and grinds the castings. The worktable is used to fix and adjust the position of the castings. The auxiliary control unit controls the operation of the entire device. The scanning and guiding unit is used to perform full-process scanning and inspection of the casting processing. The conveying unit, the cutting and grinding unit, the worktable, and the scanning and guiding unit are electrically connected to the auxiliary control unit. The cutting and grinding unit includes a cutting and grinding robot 12 and a linear motion mechanism 13. The cutting and grinding robot 12 is connected to the output execution end group of the linear motion mechanism 13. The linear motion mechanism 13 drives the cutting and grinding robot 12 to move in a straight line. The linear motion mechanism 13 realizes the linear movement of the cutting and grinding robot 12 through linear mobile devices such as threaded screws and hydraulic push rods. The cutting and grinding robot 12 moves between two processing stations through linear movement.

[0047] The cutting and grinding robot 12 is a dedicated robot for integrated cutting and grinding. Its core component is a multi-axis high-precision joint robotic arm, including a base, waist rotary joint, upper arm, lower arm, wrist joint, etc., and is equipped with a quick-change interface at its end. It can adapt to the multi-angle operation requirements of the second-order processing after the workpiece is flipped, meet the multi-directional processing of different positions of the workpiece riser, burrs, and parting lines, flexibly adjust the working angle, and eliminate processing blind spots. The end effector of the cutting and grinding robot 12 includes a cutting tool, and the cutting tool is linked with the tool magazine. The cutting tool can be automatically switched without manual intervention to achieve cutting, grinding and other operations. The power drive module of the cutting and grinding robot 12 includes a servo drive system, a spindle drive unit, a pneumatic control system, etc., to realize high and low speed switching, such as height adjustment during cutting and graded speed adjustment during grinding, to meet the power requirements of different processes. The cutting and grinding robot 12 also includes other sensor modules, communication modules and other auxiliary modules to ensure the normal operation of the linear walking mechanism 13.

[0048] The loading and handling unit includes a loading and unloading robot 14, which is a dedicated loading and unloading robot integrating handling, inspection, and linkage, and includes the following structure: The multi-axis heavy-duty robotic arm includes a fixed base, a waist rotary joint, an upper arm telescopic joint, a lower arm swing joint, and a wrist composite joint for pitch, rotation, and yaw. The end effector integrates a dual-interface quick-change tray to meet the cross-station transfer needs of manual loading stations, grinding stations, and unloading conveyor lines. It is also compatible with workpiece flipping and clamping alignment to ensure clamping and inspection accuracy. The end effector module integrates workpiece gripping and clamping as well as inspection equipment, which can simultaneously complete the transfer and inspection without the need for additional switching. The power drive control module, which includes a servo drive system, a control system, and a power supply voltage regulator unit, ensures the robotic arm's operations such as transfer, flipping, and alignment. In addition, auxiliary modules such as sensor modules and communication modules are provided to ensure the normal operation of the loading and unloading robot 14.

[0049] The scanning guidance unit is integrated and installed in 14 locations on the loading and unloading robot, and includes a 3D laser scanning module and a vision camera detection module; The 3D laser scanning module is used for coarse positioning and contour recognition, realizing overall workpiece positioning, overall shape scanning, and riser position recognition. It provides basic contour data for the system to call the corresponding cutting program, adapts to the large size error of the blank workpiece, and ensures the accuracy of trajectory planning. The vision camera inspection module is used for precise detection and residue verification. It accurately identifies the location and height of residual risers after cutting, providing accurate compensation data for subsequent grinding processes. At the same time, it works with the quality verification after grinding to ensure processing consistency and support closed-loop control. The laser rough scan of the 3D laser scanning module is used as a pre-guide to define the large outline and the processing benchmark, while the visual inspection module of the vision camera is used as a post-correction to define residual deviations and grinding compensation parameters. The combination of the two achieves the dual requirements of "large error tolerance and high-precision processing". Both modules are integrated into the loading and unloading robot 14, eliminating the need for additional testing equipment or workstations, reducing equipment footprint and overall cost. Furthermore, following the robot's movement enables multi-angle, blind-spot-free testing.

[0050] The auxiliary control unit includes a central control module, a water-cooling module, a hydraulic module, a robot control cabinet, an electrical cabinet, and other supporting facilities to enable the cutting and grinding of various types of castings with large errors.

[0051] This application enables on-demand processing of incoming parts. The control system of this application does not require manual teaching or offline programming for each new workpiece or each individual of the same workpiece. The worker only needs to clamp the workpiece and specify the processing task, such as "remove all flash" or "grind this weld", and the system can automatically identify, plan and execute the operation. Tolerance to large size errors: The system is equipped with a perception and decision-making module that can acquire the actual three-dimensional shape of the workpiece in real time and intelligently match and compare it with the theoretical model to automatically generate processing trajectories and process parameters that adapt to actual individual deviations. Ensuring processing quality and consistency: By integrating closed-loop control technologies such as vision and servo, the cutting or grinding tools can adaptively follow the true contour of the workpiece, overcome fluctuations caused by blank errors, and obtain stable processing quality that is superior to manual processing. Lowering technical barriers and overall costs: Transforming complex "programming" work into simple "task assignment" reduces the requirements for operators' robot programming skills, while reducing downtime programming time and scrap rate by improving equipment utilization, thereby reducing overall production costs.

[0052] The process flow of this application is as follows: The worker uses the lifting mechanism to move the casting to the positioning fixture at the manual loading station. After it is placed securely, the worker exits and presses the start button. 2. The automatic door closes, the loading and unloading robot 14 grabs the casting and moves it to the worktable of the robot's automatic grinding station. The automatic clamping device clamps the casting to complete the loading. 3. The loading and unloading robot 14 uses its 3D laser scanning module to position the casting and perform a rough scan of the overall shape of the casting and the position of the riser; the auxiliary control unit calls the corresponding casting cutting program according to the scanning results. IV. The cutting and grinding robot 12 starts to cut the riser of the casting; 5. After the riser cutting is completed, the loading and unloading robot 14, equipped with a vision camera detection module, scans the position and height of the remaining riser after cutting; the cutting and grinding robot 12 is started to grind the cutting residue; VI. After the first stage of machining of the casting is completed, the loading and unloading robot 14 unloads the casting, flips it over, and clamps it onto the worktable for the second stage of machining. 7. The loading and unloading robot 14 uses its 3D laser scanning module to position the casting and perform a rough scan of the overall shape of the casting; it then calls the corresponding casting cutting program based on the scan results. 8. The cutting and grinding robot 12 starts to cut the riser of the casting; 9. After the riser cutting is completed, the loading and unloading robot 14, equipped with a vision camera detection module, scans the position and height of the remaining riser after cutting; 10. The cutting and grinding robot 12 starts to grind the cutting residue, burrs and parting lines; 11. The loading and unloading robot 14 clamps the new casting onto the worktable for the first stage of processing and scans it. 12. After the second stage of processing of the casting is completed, the loading and unloading robot 14 unloads the casting to the unloading conveyor line.

[0053] This application integrates 3D laser coarse scanning positioning and visual precision detection functions to achieve full-process detection of workpiece shape, riser position and residual riser height, providing accurate data support for cutting and grinding; The cutting and grinding robot 12 and the loading and unloading robot 14 work together to achieve seamless connection of workpiece handling, flipping, clamping and grinding operations, and simultaneously complete the loading and scanning of new workpieces during the second processing, improving work efficiency. By integrating manual feeding triggering, automatic door linkage, positioner clamping, processing inspection, and unloading conveying, a continuous processing closed loop without human intervention is constructed to ensure the stability and continuity of the processing flow.

[0054] The workbench includes two processing stations, which are arranged adjacent to each other. Each processing station includes a support base 1. Two left and right distributed support side plates 2 are detachably connected above the support base 1. The detachable connection can be achieved by bolts. A mounting frame 3 is provided between the two support side plates 2. The two support side plates 2 and the mounting frame 3 are connected by AC rotating component. The AC rotating component causes the mounting frame 3 to rotate around the X-axis and Z-axis respectively. Two symmetrical clamping support components are provided on the upper part of the mounting frame 3. The width of the clamping support components is adaptively adjusted according to the size of the casting. The two clamping support components are respectively connected to the synchronous adjustment component. The synchronous adjustment component is installed inside the mounting frame 3 and is used to synchronously adjust the position of the two clamping support components.

[0055] In this technical solution, the scanning guidance unit enables full-process detection of the casting's shape, riser position, and residual riser height, providing accurate data support for cutting and grinding. It is suitable for cutting and grinding various types of castings with large errors. At the same time, the handling unit and the cutting and grinding unit work together in two-stage continuous processing to achieve seamless connection between casting handling, flipping, clamping, and grinding operations. Furthermore, the scanning of new workpieces is completed simultaneously during the second processing stage, improving work efficiency. Moreover, the linkage and automated closed-loop control of each process integrates manual loading triggering, automatic door linkage, casting clamping, processing inspection, and unloading and conveying, constructing a continuous processing closed loop without human intervention, ensuring the stability and continuity of the processing flow. The positions of the two clamping support components are adjusted synchronously by the synchronous adjustment component, so that the distance between the two clamping support components can be adjusted and controlled. This allows the clamping support components on both sides to clamp and place castings of different sizes, increasing the flexibility of the worktable and making it suitable for various types of castings. Furthermore, the width of the clamping support components can be adaptively adjusted according to the size of the casting, further expanding the applicability of the worktable.

[0056] The AC rotating component includes an A-axis rotating assembly 4 and a C-axis rotating assembly 5. Both ends of the A-axis rotating assembly 4 are rotatably connected to the supporting side plates 2 on both sides. The output end of the A-axis rotating assembly 4 is connected to the C-axis rotating assembly 5, and the output end of the C-axis rotating assembly 5 is connected to the mounting frame 3. The A-axis rotating assembly 4 drives the C-axis rotating assembly 5 and the mounting frame 3 to rotate around the X-axis, and the C-axis rotating assembly 5 drives the mounting frame 3 to rotate around the Z-axis.

[0057] In this technical solution, the A-axis rotating assembly 4 drives the C-axis rotating assembly 5 and the mounting frame 3 to rotate around the X-axis, and the C-axis rotating assembly 5 drives the mounting frame 3 and other structures to rotate around the Z-axis.

[0058] The A-axis rotation assembly 4 includes a rotating frame 41, and a C-axis rotation assembly 5 is installed in the inner cavity of the rotating frame 41. A-axis rotating plates 42 are connected to both sides of the rotating frame 41. The two A-axis rotating plates 42 are rotatably connected to the two support side plates 2 respectively, and one of the A-axis rotating plates 42 is connected to the output end of the A-axis power source 43, which is installed at the support side plate 2.

[0059] Specifically, the inner wall of the rotating frame shell 41 is connected with multiple reinforcing vertical plates to increase the structural strength of the rotating frame shell 41; The rotating frame 41 has multiple heat dissipation holes on its side to dissipate heat from the C-axis rotating assembly 5.

[0060] In this technical solution, the angles of the C-axis rotating assembly 5, the mounting frame 3, and the castings in the X-axis direction are adjusted and controlled by the A-axis rotating assembly 4.

[0061] In use, the A-axis power source 43 drives the corresponding A-axis rotating plate 42 to rotate around the X-axis, thereby driving the rotating frame 41 and another A-axis rotating plate 42 to rotate, which in turn drives the C-axis rotating assembly 5 and castings and other structures to rotate.

[0062] The C-axis rotation assembly 5 includes a lower rotation shaft 51. The two ends of the lower rotation shaft 51 are rotatably connected to the upper and lower sides of the rotating frame 41, respectively. The surface of the lower rotation shaft 51 is connected to the rotation output part of the drive component. The drive component is installed in the inner cavity of the rotating frame 41. The upper end of the lower rotating shaft 51 is connected to the C-axis rotating plate 52, and the top of the C-axis rotating plate 52 is connected to the upper rotating cylinder 53. The surface of the upper rotating cylinder 53 is fixedly connected to the upper and lower surfaces of the mounting frame 3.

[0063] Specifically, the drive component includes a C-axis power source 54, which is installed in the inner cavity of the rotating frame 41. The output end of the C-axis power source 54 is connected to a main gear 55, and the side of the main gear 55 meshes with a secondary gear 56. The secondary gear 56 is connected to the surface of the lower rotating shaft 51.

[0064] To ensure the stability of the rotating frame 3, an annular track 57 is connected to the top of the rotating frame 41. A track groove is opened on the bottom surface of the C-axis rotating plate 52, and the annular track 57 is set in the track groove. The annular track 57 is slidably connected to the C-axis rotating plate 52 through the track groove. Furthermore, multiple reinforcing brackets 58 are connected between the C-axis rotating plate 52 and the mounting frame 3. The reinforcing brackets 58 are used to provide support for the mounting frame 3, increase the strength of the mounting frame 3, and make the mounting frame 3 more stable when rotating.

[0065] Furthermore, the top of the rotating frame 41 is connected to two symmetrically distributed placement platforms. The top of these placement platforms contacts the bottom of the mounting frame 3, providing auxiliary support for the mounting frame 3.

[0066] In this technical solution, the angles of the mounting frame 3 and castings in the Z-axis direction are adjusted and controlled by the C-axis rotation component 5.

[0067] In use, the C-axis power source 54 drives the main gear 55 to rotate, which in turn drives the secondary gear 56 to rotate, thereby driving the lower rotating shaft 51, the C-axis rotating plate 52 and the upper rotating cylinder 53 to rotate. When the C-axis rotating plate 52 rotates, it rotates around the annular track 57. At the same time, the C-axis rotating plate 52 drives multiple reinforcing brackets 58 to rotate. When the upper rotating cylinder 53 and the reinforcing brackets 58 rotate, they drive the mounting frame 3 to rotate, which in turn drives the castings and other structures to rotate around the Z-axis.

[0068] A central support assembly 6 is provided in the inner cavity and above the upper rotating cylinder 53; The middle support assembly 6 includes a linear lifting device 61, which is installed in the inner cavity of the upper rotating cylinder 53. The output end of the linear lifting device 61 is slidably connected to the top surface of the upper rotating cylinder 53, and the output end of the linear lifting device 61 is connected to a bottom support plate 62.

[0069] Specifically, the bottom support plate 62 is composed of a rigid plate and an anti-slip pad connected above it. The bottom of the rigid plate is connected to the upper end of the linear lifting device 61, and the anti-slip pad contacts the bottom of the casting to form a flexible contact. This not only adapts to the bottom of castings of different shapes, but also avoids damage to the bottom of the casting.

[0070] In this technical solution, the casting can be lifted from the bottom by the central support component 6, which increases the stability of the casting during processing.

[0071] In use, the linear lifting device 61 drives the bottom support plate 62 to move, so that the bottom support plate 62 is in close contact with the bottom of the casting, thereby lifting the casting, increasing the stability of the casting during cutting, grinding and other processing, while reducing the force of the casting on the clamping support component and extending the service life of the clamping support component.

[0072] The clamping support component includes a central frame shell 7 and side clamping support plates 8. Side clamping support plates 8 are provided on both sides of the central frame shell 7, and the side clamping support plates 8 on both sides can move synchronously through the extension and retraction assembly 9. The bottom of the middle frame 7 is connected to the output actuator of the synchronous adjustment component.

[0073] In this technical solution, the positions of the two side clamping plates 8 are adjusted synchronously by the unfolding and retracting assembly 9.

[0074] The unfolding and retracting assembly 9 includes a central moving rack 91, with rotating gears 92 meshing on both the upper and lower sides of the central moving rack 91, and side moving racks 93 meshing on the opposite sides of the two rotating gears 92. The opposite ends of the rotating gear 92 and the side moving rack 93 are slidably connected to the side of the central frame 7. The ends of the rotating gear 92 away from the rotating gear 92 and the side moving rack 93 away from the central frame 7 are respectively connected to the side of the two side clamping plates 8 near the central frame 7.

[0075] In this technical solution, the central moving rack 91 and the side moving rack 93 move synchronously towards or away from each other, adjusting the positions of the two side clamping plates 8 respectively, so that the side clamping plates 8 on both sides can move synchronously towards or away from each other.

[0076] A connecting post 94 is connected to one side of the central moving rack 91. The surface of the connecting post 94 is slidably connected to one side of the central frame 7. A push-pull plate 95 is connected to the end of the connecting post 94 away from the central moving rack 91. One side of the push-pull plate 95 is connected to the output end of the linear telescopic device 96, which is installed on the outside of the middle frame 7.

[0077] Specifically, a pre-set opening is provided on one side of the middle frame shell 7, and the connecting strip 94 extends to the outside of the middle frame shell 7 through the sliding opening.

[0078] Furthermore, in order to ensure the stability of the movement of the push-pull plate 95, multiple positioning rails 97 are connected to the outside of the middle frame shell 7. A sliding opening is provided on the side of the push-pull plate 95 near the middle frame shell 7, and the positioning rails 97 are slidably connected to the push-pull plate 95 through the sliding opening. Both the central moving rack 91 and the side moving rack 93 have sliding openings. Multiple anti-deviation strips 98 are connected to the inner wall of the central frame 7. The multiple anti-deviation strips 98 are slidably connected to the corresponding central moving rack 91 or side moving rack 93 through the sliding openings to increase the stability of the central moving rack 91 and side moving rack 93 when they move.

[0079] In this technical solution, the linear telescopic device 96 provides driving force for the movement of the side clamp support plate 8.

[0080] In use, depending on the size of the casting, the connecting bar column 94 drives the push-pull plate 95 to move along the positioning track 97, thereby driving the connecting bar column 94 to move in the same direction, and then driving the central moving rack 91 to move in the same direction. When the central moving rack 91 moves, it drives the two rotating gears 92 to rotate, which in turn drives the side moving racks 93 on both sides to rotate. When the central moving rack 91 and the side moving rack 93 move, they respectively drive the corresponding side clamping support plates 8 to move in the same direction. Under the action of the rotating gears 92, the central moving rack 91 and the side moving rack 93 move in opposite directions. Therefore, the two side clamping support plates 8 can move synchronously towards or away from each other to adapt to castings of different sizes.

[0081] The synchronous adjustment component includes an adjustment assembly 10, which includes two fixed side plates 101. Threaded shafts 102 are rotatably connected to opposite sides of the two fixed side plates 101. Both threaded shafts 102 are connected to the output end of the power assembly 11. The end of the threaded shaft 102 away from the fixed side plate 101 is rotatably connected to the inner wall of the mounting frame 3. The thread directions of the two threaded shafts 102 are opposite. A movable plate 103 is threadedly connected to the surface of the threaded shaft 102. Multiple follower bars 104 are connected to the top of the movable plate 103. The top of the follower bars 104 is connected to the bottom of the middle frame 7.

[0082] Specifically, the top surface of the mounting frame 3 has multiple movable openings, and the surface of the follower column 104 is slidably connected to the top surface of the mounting frame 3 through the movable openings.

[0083] Furthermore, the inner wall of the mounting frame 3 is connected to multiple limiting shafts 105. The end of the limiting shaft 105 away from the mounting frame 3 is connected to one side of the fixed side plate 101, and the surface of the limiting shaft 105 is slidably connected to the movable plate 103.

[0084] Multiple rolling wheels 106 are rotatably connected to the bottom of the middle frame shell 7. The rolling wheels 106 contact the top surface of the mounting frame shell 3. When the middle frame shell 7 moves, it drives the rolling wheels 106 to roll, thereby providing auxiliary support for the middle frame shell 7. This makes the movement of the middle frame shell 7 smoother and reduces the force borne by the follower bar 104, extending the service life of the follower bar 104 and other structures.

[0085] In this technical solution, the distance between the two central frame shells 7 is adjusted by the adjustment component 10 to accommodate castings of different sizes.

[0086] The power assembly 11 includes a drive shaft 111, with both ends of the drive shaft 111 rotatably connected to two fixed side plates 101, and both ends of the drive shaft 111 rotatably connected to the inner sides of two auxiliary brackets 115, with the two auxiliary brackets 115 respectively connected to one side of the two fixed side plates 101. The two ends of the drive shaft 111 are respectively connected to the two threaded shafts 102 through two first drive parts 112. The first drive parts 112 are located inside the auxiliary bracket 115. The surface of the drive shaft 111 is connected to the output end of the adjustment power source 113 through the second drive part 114. The second drive part 114 is installed in the inner cavity of the mounting frame 3.

[0087] Specifically, both the first transmission part 112 and the second transmission part 114 are composed of two meshing gears. The two gears at the first transmission part 112 are connected to the transmission shaft 111 and the threaded shaft 102, respectively, and the two gears at the second transmission part 114 are connected to the transmission shaft 111 and the output end of the adjustment power source 113, respectively.

[0088] In this technical solution, the power component 11 provides driving force for the operation of the adjustment component 10.

[0089] In use, the power source 113 is adjusted to rotate according to the size of the casting. The power is transmitted to the transmission shaft 111 through the second transmission part 114, which drives the transmission shaft 111 to rotate. The transmission shaft 111 transmits the power to the two threaded shafts 102 through the two first transmission parts 112, which drives the two threaded shafts 102 to rotate. When the threaded shaft 102 rotates, it drives the moving plate 103 to move along the limiting shaft 105. At this time, the two moving plates 103 move towards each other or away from each other. When the movable plate 103 moves, it drives the follower column 104 to move in the same direction, thereby driving the middle frame shell 7 to move in the same direction, and then driving the side clamp support plate 8 and other structures to move in the same direction, adjusting the distance between the two middle frame shells 7, so as to accommodate more castings of various sizes.

[0090] Linear lifting device 61 and linear telescopic device 96 are electric push rod assemblies, hydraulic lifting cylinder assemblies, lifting cylinder assemblies or other linear devices with autonomous telescopic function.

[0091] The A-axis power source 43, C-axis power source 54, and positioning power source 113 are motor sets or other devices that can output rotational kinetic energy.
