Description

Technical Field

[0001] This invention relates to the field of high-end equipment manufacturing, and more specifically, to a grinding device for the production and processing of machine tool parts. Background Technology

[0002] In the production and processing of machine tool parts, grinding is a crucial process to ensure surface finish, dimensional accuracy, and deburring. Traditional grinding methods often rely on manual operation or semi-automatic equipment, which suffers from low efficiency, high labor intensity, and inconsistent grinding quality. In recent years, automated grinding equipment has become increasingly popular. It uses robotic arms or specialized fixtures to position and transport workpieces, working in conjunction with grinding wheels to improve production efficiency.

[0003] However, in existing technologies, workpieces after grinding typically need to be transferred to a separate inspection station for quality checks, such as visual inspection. This not only increases the floor space required for the production line but also results in long inspection cycles and large positioning errors due to the multiple handling and reclamping of the workpieces, affecting inspection accuracy and overall production efficiency.

[0004] Furthermore, for cylindrical or ring-shaped workpieces, comprehensive surface defect inspection is required for their inner walls, outer walls, and end faces. Traditional clamping methods may obscure some areas during inspection, making it difficult to achieve all-round, blind-angle inspection. To inspect the obscured areas, secondary clamping is often required, which not only prolongs the inspection time but also increases the risk of workpiece collision damage. Summary of the Invention

[0005] This invention provides a grinding device for the production and processing of machine tool parts, which solves the technical problems in related technologies such as long inspection cycle time and large positioning error of the ground products, which affect the inspection accuracy and overall production efficiency.

[0006] This invention provides a grinding device for the production and processing of machine tool parts, including a worktable;

[0007] The workbench is equipped with a grinding mechanism and a product inspection mechanism. The grinding mechanism includes an active grinding wheel and a driven grinding wheel that are rotatably mounted on the workbench. A grinding gap is left between the active grinding wheel and the driven grinding wheel to store the workpiece. The active grinding wheel and the driven grinding wheel rotate in opposite directions.

[0008] The product inspection mechanism includes a vision inspection component and a robotic arm mounted on a workbench. A mounting frame is fixedly mounted at the front end of the robotic arm. A main pulley and a rotary drive component one for driving the main pulley to rotate are mounted on the mounting frame. Auxiliary pulleys are rotatably connected to both sides of the bottom of the main pulley. The main pulley and the two auxiliary pulleys are connected by a transmission belt. A rotating frame is rotatably connected to the bottom of the mounting frame. A rotary drive component two is mounted on the mounting frame and is used to drive the rotating frame to rotate.

[0009] The rotating frame is equipped with a clamping assembly, which includes two half pulleys and a power component for driving the two half pulleys to move closer or further apart. When the two half pulleys move closer together, they form a complete pulley. One side of the complete pulley is in contact with the transmission belt. The two half pulleys are used to clamp the workpiece.

[0010] In a preferred embodiment, the grinding mechanism further includes a gantry frame mounted on the worktable and positioned directly above the grinding gap. A dual-axis moving mechanism is installed inside the gantry frame, and the output end of the dual-axis moving mechanism is connected to a U-shaped gripper. A loading rack and a unloading rack are respectively provided on both sides of the axial direction of the active grinding wheel. The loading rack is located on the side of the active grinding wheel away from the product inspection mechanism, and the unloading rack is located on the side of the active grinding wheel closer to the product inspection mechanism.

[0011] In a preferred embodiment, the power component includes a cylinder, which is fixedly mounted on a rotating frame. A connecting rod is fixedly mounted on the output end of the cylinder, and rollers are rotatably connected to both ends of the connecting rod. An annular groove is formed on the upper surface of the half-pulley, and two rollers are rolled inside the annular groove. The cross-section of the annular groove is convex.

[0012] In a preferred embodiment, a slider is fixedly connected to the bottom of the half pulley, and a slide rail is fixedly connected to the mounting bracket. When the two half pulleys move away from each other, the slider slides inside the slide rail. A positioning hole is opened at one end of the half pulley, and a positioning pin is fixedly connected to the other end of the half pulley. When the two half pulleys approach each other and merge together, the positioning pin is inserted into the positioning hole.

[0013] In a preferred embodiment, the inner sides of both half pulleys are detachably connected to half rings, and a number of balls are rolled on the inner wall of the half rings for clamping the outer wall of the workpiece.

[0014] In a preferred embodiment, the lower part of the main pulley is a straight belt section, the axis of which is perpendicular to the axis of the half pulley, and one side of the complete pulley is pressed against the straight belt section. The rotation drive component 2 drives the rotating frame to rotate around the axis of the straight belt section.

[0015] In a preferred embodiment, the grinding device further includes a pressing assembly, which includes an eccentric wheel mounted on the front surface of the main pulley, a rod disposed below the eccentric wheel, the rod being vertically inserted into the mounting bracket, a pressure plate being fixedly mounted on the upper end of the rod, and the outer surface of the eccentric wheel pressing against the upper side of the pressure plate.

[0016] In a preferred embodiment, a spring is sleeved on the outer side of the insertion rod, and the two ends of the spring are pressed against the mounting bracket and the pressure plate respectively. The pressure plate is an arc shape with both ends facing upwards. The outer surface of the main pulley is pressed against the inner wall of the pressure plate. A pressure rod is fixedly installed on one side of the pressure plate and is used to press down on the workpiece.

[0017] In a preferred embodiment, the robotic arm includes a base, a rotating seat rotatably connected to the base, a large arm rotatably connected to the rotating seat, a small arm rotatably connected to the upper end of the large arm, a rotating arm rotatably connected to the front end of the small arm, an end arm rotatably connected to the front end of the rotating arm, and a mounting bracket fixedly mounted on the end arm.

[0018] In a preferred embodiment, the visual inspection component includes a bracket fixedly mounted on a workbench, with a ring light source mounted on the upper end of the bracket and a visual camera positioned directly below the ring light source.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention integrates the grinding mechanism and the product inspection mechanism on the same workbench. While the robotic arm completes the grinding loading / unloading, it can directly transfer the workpiece to the vision inspection component for inspection, realizing the integration of grinding and inspection. This eliminates the need for workpiece transfer and secondary clamping between different workstations, significantly shortens the production cycle, and improves the overall production efficiency.

[0021] This invention, by setting up a rotating frame driven by a rotary drive component, and a transmission system consisting of a main pulley, a secondary pulley, and a transmission belt, can drive the clamped workpiece to achieve axial rotation and spatial posture changes (such as switching between vertical and horizontal states). Combined with the pressing component, the position of the workpiece in the clamping assembly can be dynamically adjusted during the inspection process, exposing the areas that were originally clamped and obscured. This enables 360° all-round, blind-spot-free visual inspection of the inner wall, outer wall, and end face of the workpiece, ensuring the comprehensiveness and accuracy of the inspection.

[0035] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0036] like Figures 1-12 As shown, a grinding device for manufacturing and processing machine tool parts includes a worktable 1;

[0037] A grinding mechanism 7 and a product inspection mechanism are installed on the workbench 1. The grinding mechanism 7 includes an active grinding wheel 72 and a driven grinding wheel 73 rotatably mounted on the workbench 1. A grinding gap is left between the active grinding wheel 72 and the driven grinding wheel 73. The grinding gap is used to store the workpiece 100. The active grinding wheel 72 and the driven grinding wheel 73 rotate in opposite directions.

[0038] The grinding mechanism 7 also includes a gantry frame 71, which is mounted on the worktable 1 and is located directly above the grinding gap. A dual-axis moving mechanism 711 is installed inside the gantry frame 71. The output end of the dual-axis moving mechanism 711 is connected to a U-shaped gripper 76. The active grinding wheel 72 has an loading rack 74 and a unloading rack 75 on its axial sides respectively. The loading rack 74 is located on the side of the active grinding wheel 72 away from the product inspection mechanism, and the unloading rack 75 is located on the side of the active grinding wheel 72 closer to the product inspection mechanism.

[0039] The product inspection mechanism includes a vision inspection component 2 and a robotic arm 3 installed on a workbench 1. A mounting frame 4 is fixedly installed at the front end of the robotic arm 3. A main pulley 41 and a rotary drive component 40 for driving the main pulley 41 to rotate are installed on the mounting frame 4. Auxiliary pulleys 42 are rotatably connected to both sides of the bottom of the main pulley 41. The main pulley 41 and the two auxiliary pulleys 42 are connected by a transmission belt 43. A rotating frame 44 is rotatably connected to the bottom of the mounting frame 4. A rotary drive component 45 is installed on the mounting frame 4. The rotary drive component 45 is used to drive the rotating frame 44 to rotate.

[0040] A clamping assembly 5 is installed on the rotating frame 44. The clamping assembly 5 includes two half pulleys 51 and a power component 52 for driving the two half pulleys 51 to move closer or further apart. When the two half pulleys 51 move closer and merge together, they form a complete pulley. One side of the complete pulley is in contact with the transmission belt 43. The two half pulleys 51 are used to clamp the workpiece 100.

[0041] It should be noted that a grinding head motor is installed at one axial end of the active grinding wheel 72, driving the active grinding wheel 72 to rotate. A gear is installed at one axial end of the driven grinding wheel 73, which meshes with a gear mounted on the rotating shaft of the active grinding wheel 72, thereby causing the driven grinding wheel 73 to rotate as well. The grinding gap is less than the diameter of the workpiece 100. The dual-axis moving mechanism 711 consists of a linear motor and a lifting cylinder. The output end of the linear motor is equipped with a lifting cylinder, and the output end of the lifting cylinder is connected to the U-shaped gripper 76. The U-shaped gripper 76 has a cylinder drive that can move and clamp. The linear motor controls the movement of the U-shaped gripper 76 in the X-axis direction, and the lifting cylinder controls the movement of the U-shaped gripper 76 in the Y-axis direction.

[0042] The grinding process of workpiece 100 is as follows: workpiece 100 is placed on the loading rack 74 manually or by a robot. Then, the U-shaped gripper 76 clamps the workpiece 100 on the loading rack 74 into the grinding gap. The head frame drives the workpiece 100 to start rotating, the grinding head motor starts, and the grinding wheel rotates at high speed. The grinding wheel wraps around the workpiece 100 in the grinding gap and grinds it from all directions to achieve the required surface finish. After grinding, the workpiece 100 located in the grinding gap is taken out by the U-shaped gripper 76 and placed on the unloading rack 75 for storage. The robot arm 3 then transfers the ground workpiece 100 to the product inspection mechanism for visual inspection.

[0043] It should be further explained that both the first rotary drive component 40 and the second rotary drive component 45 are servo motors. The first rotary drive component 40 drives the main pulley 41 to rotate, which in turn drives the two auxiliary pulleys 42 to rotate via the transmission belt 43. Since the complete pulley is in contact with the transmission belt 43, the complete pulley can also be driven to rotate when the transmission belt 43 is in motion.

[0044] In the above technical solutions, such as Figure 7 and Figure 10 As shown, the power component 52 includes a cylinder 521, which is fixedly mounted on the rotating frame 44. A connecting rod 522 is fixedly mounted on the output end of the cylinder 521. Rollers 523 are rotatably connected to both ends of the connecting rod 522. An annular groove 511 is formed on the upper surface of the half pulley 51. The two rollers 523 are rolled inside the annular groove 511. The cross-section of the annular groove 511 is convex.

[0045] It should be noted that when the full pulley rotates, the roller 523 rolls within a complete annular groove 511 formed by the two annular grooves 511. Since the cross-section of the annular groove 511 is convex, the roller 523 will not move out of the annular groove 511 during rolling, thus the roller 523 can support the half pulley 51. When it is necessary to move the two half pulleys 51 closer or further apart, the cylinder 521 drives the connecting rod 522 and the two rollers 523 mounted on the connecting rod 522 to move.

[0046] In the above technical solutions, such as Figure 4 and Figure 11 As shown, the visual inspection component 2 includes a bracket 21, which is fixedly installed on the worktable 1. A ring light source 22 is installed on the upper end of the bracket 21, and a visual camera 23 is arranged directly below the ring light source 22.

[0047] It should be noted that the visual camera 23 is used for image recognition, and the ring light source 22 is used for supplementary lighting.

[0048] In this embodiment, the specific implementation method is as follows: Figure 8 The cylindrical workpiece 100 shown has a perforated upper end and a completely open lower end. For visual inspection of defects on its inner and outer surfaces, the workpiece 100 is first transported by a conveying device. Then, a robotic arm 3 moves the clamping assembly 5 to the position of the workpiece 100 to clamp it. Specifically, during clamping, the corresponding power components 52 of the two half-pulleys 51 are activated; that is, the cylinder 521 pulls the connecting rod 522 and the roller 523 to move, causing the two half-pulleys 51 to move away from each other. Then, the robotic arm 3 moves, positioning the workpiece 100 between the two half-pulleys 51. Next, the cylinder 521 pushes the connecting rod 522 and the roller 523 to move, causing the two half-pulleys 51 to move closer together, thus clamping the workpiece 100. The robotic arm 3 then moves the workpiece 100 directly above the visual inspection assembly 2, where it is photographed and identified by the visual camera 23. The processing system then identifies the surface defects.

[0049] like Figure 12As shown, with the fully open end of workpiece 100 facing upwards and the perforated structure facing downwards, after the clamping assembly 5 clamps workpiece 100, it is in the state shown in ①. At this time, the ring light source 22 can take pictures and identify the inner surface of workpiece 100 from the upwards. Then, the rotation drive component 2 45 drives the rotating frame 44 to rotate 90 degrees clockwise, which is the state shown in ②. In this state, the rotation drive component 1 40 drives the main pulley 41 to rotate. The main pulley 41 drives the two auxiliary pulleys 42 to rotate through the transmission belt 43. After the transmission belt 43 is driven, it can drive the complete pulley to rotate. In this way, the workpiece 100 clamped by the complete pulley can rotate. While the workpiece 100 is rotating, the ring light source 22 takes pictures and identifies the defects on the outer wall of the workpiece 100. Then, the rotation drive component 45 drives the rotating frame 44 to rotate 90 degrees clockwise, which is the state shown in ③. In this state, the workpiece 100 with the hole structure faces downward. At this time, the ring light source 22 can take pictures and identify the outer end face of the workpiece 100 with the hole structure from the top.

[0050] The above technical solution, through the arrangement of mounting frame 4, main pulley 41, auxiliary pulley 42, transmission belt 43 and clamping assembly 5, can clamp workpiece 100 on the one hand, and interchange the upper and lower ends of workpiece 100 to achieve the purpose of identifying the inner wall and outer end of workpiece 100 on the other hand. Furthermore, workpiece 100 can be rotated to a horizontal axis, which can also drive workpiece 100 to rotate on its own to take pictures and identify the outer wall of workpiece 100.

[0051] In this embodiment, the above technical solution can be used to photograph and identify the inner surface, outer wall and outer end face of the workpiece 100 with holes. However, the part clamped by the half pulley 51 cannot be photographed and identified. Therefore, the following technical solution is proposed.

[0052] Specifically, such as Figure 6 and Figure 8 As shown, the industrial robot also includes a pressing component 6. The pressing component 6 includes an eccentric wheel 61 mounted on the front surface of the main pulley 41. A rod 62 is provided below the eccentric wheel 61. The rod 62 is vertically inserted into the mounting frame 4. A pressure plate 63 is fixedly mounted on the upper end of the rod 62. The outer surface of the eccentric wheel 61 presses against the upper side of the pressure plate 63.

[0053] Furthermore, a spring 64 is sleeved on the outer side of the insertion rod 62. The two ends of the spring 64 are pressed against the mounting bracket 4 and the pressure plate 63 respectively. The pressure plate 63 is an arc shape with both ends facing upward. The outer surface of the main pulley 41 is pressed against the inner wall of the pressure plate 63. A pressure rod 65 is fixedly installed on one side of the pressure plate 63. The pressure rod 65 is used to press down the workpiece 100.

[0054] It should be noted that during the transition from state ② to state ③, the second rotary drive component 45 drives the rotating frame 44 to rotate towards the side of the downward pressing assembly 6. During this process, the first rotary drive component 40 drives the main pulley 41, the auxiliary pulley 42, and the complete pulley to rotate, causing the workpiece 100 to rotate. Simultaneously, the main pulley 41 drives the eccentric wheel 61 to rotate, pressing the pressure plate 63 downwards. This causes the pressure plate 63 to move the insertion rod 62 up and down reciprocally. The spring 64 is used to reset the insertion rod 62 and the pressure plate 63 upwards. Furthermore, the pressure plate 63 can drive the pressure rod 65 to move up and down reciprocally, and the pressure rod 65 contacts the end of the workpiece 100, pressing it downwards. This causes the workpiece 100 to move downwards relative to the complete pulley. The state after the movement is completed is as follows: Figure 12 The state shown is ③, that is Figure 8 The state shown is as follows. In state ③, after photographing and recognizing the outer end face of the perforated structure of workpiece 100, the rotation drive component 2 45 drives the rotating frame 44 to rotate 90 degrees counterclockwise, which is the state shown in state ④. In this state, the rotation drive component 1 40 drives the main pulley 41 to rotate. The main pulley 41 drives the two auxiliary pulleys 42 to rotate through the transmission belt 43. After the transmission belt 43 is driven, it can drive the complete pulley to rotate. In this way, the workpiece 100 held by the complete pulley can rotate. While the workpiece 100 is rotating, the ring light source 22 takes pictures and recognizes it. In this way, the defects on the outer wall of the workpiece 100 can be identified, that is, the parts that were not photographed and recognized before due to being blocked by the half pulley 51 can be identified.

[0055] The above technical solution presses the workpiece 100 downward when it is turned around, thereby changing the position of the half pulley 51 clamping the workpiece 100. This allows the identification of the part that was not previously photographed and identified because it was blocked by the half pulley 51. The entire identification process of the workpiece 100 does not require secondary clamping, saving detection time.

[0056] Refer to the instruction manual appendix Figures 7-10 A slider 512 is fixedly connected to the bottom of the half pulley 51, and a slide rail 53 is fixedly connected to the mounting bracket 4. When the two half pulleys 51 move away from each other, the slider 512 slides inside the slide rail 53.

[0057] It should be noted that when the two half pulleys 51 merge to form a complete pulley, the slider 512 disengages from the positioning hole 513, thus not affecting the rotation of the half pulley 51. When the two half pulleys 51 separate, the slider 512 slides into the interior of the slide rail 53, thereby improving the stability of the half pulley 51.

[0058] Refer to the instruction manual appendix Figure 10One end of the half pulley 51 is provided with a positioning hole 513, and the other end of the half pulley 51 is fixedly connected with a positioning pin 514. When the two half pulleys 51 approach each other and merge together, the positioning pin 514 is inserted into the interior of the positioning hole 513.

[0059] It should be noted that when the two half pulleys 51 are combined to form a complete pulley, the locating pin 514 on one half pulley 51 is inserted into the locating hole 513 on the other half pulley 51. This improves the integrity of the complete pulley and enhances its stability during rotation.

[0060] Refer to the instruction manual appendix Figures 9-10 Both half pulleys 51 are detachably connected to a half ring 54 on their inner sides. Several balls 55 are rolled on the inner wall of the half ring 54. The balls 55 are used to clamp the outer wall of the workpiece 100.

[0061] It should be noted that the semi-ring 54 is installed inside the semi-pulley 51 by screws. Semi-rings 54 with different inner diameters can be installed inside the semi-pulley 51, so as to accommodate workpieces 100 with different diameters. The ball bearings 55 are used to clamp the workpiece 100 on the one hand, and to reduce friction when the pressing assembly 6 presses down on the workpiece 100, so as to prevent scratches on the outer wall of the workpiece 100.

[0062] Refer to the instruction manual appendix Figure 6 The lower part of the main pulley 41 is a straight belt section 430. The axis of the straight belt section 430 is perpendicular to the axis of the half pulley 51. One side of the complete pulley is pressed and contacted with the straight belt section 430. The rotation drive component 2 45 drives the rotating frame 44 to rotate around the axis of the straight belt section 430.

[0063] It should be noted that the purpose of rotating the rotating frame 44 around the axis of the straight belt section 430 is to ensure that the straight belt section 430 is always in contact with and pressed against the complete pulley when the complete pulley rotates together with the rotating frame 44.

[0064] Refer to the instruction manual appendix Figure 4 and Figure 5 The robotic arm 3 includes a base 31, a rotating seat 32 rotatably connected to the base 31, a large arm 33 rotatably connected to the rotating seat 32, a small arm 34 rotatably connected to the upper end of the large arm 33, a rotating arm 35 rotatably connected to the front end of the small arm 34, an end arm 36 rotatably connected to the front end of the rotating arm 35, and a mounting bracket 4 fixedly mounted on the end arm 36.

[0065] It should be noted that the rotating base 32, the upper arm 33, the lower arm 34, the rotating arm 35, and the end arm 36 are all driven by motors.

[0066] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
