Description

Technical Field

[0001] The invention relates to the technical field of parts processing, and in particular to a reversing grinding device and a grinding method for special-shaped parts. Background Art

[0002] Special-shaped parts refer to parts with irregular shapes. They are widely used. The operation of many machines is inseparable from special-shaped parts. Compared with traditional standard parts, special-shaped parts can better achieve the purpose of using different machines in different environments and enable the machines to operate better. Therefore, special-shaped parts are also invested in production in large quantities.

[0003] Grinding is an important procedure in the processing of special-shaped parts, which is mainly for polishing the surface of the parts. However, many special-shaped parts grinding equipment now have many limitations when used. For example, when grinding parts, the parts cannot be reversed, and manual adjustment is required to achieve the purpose of grinding different parts of the parts. For this reason, we propose a reversing grinding device and grinding method for special-shaped parts. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that many special-shaped parts grinding devices in the prior art have many limitations when in use, such as the inability to reverse the parts when grinding, and manual adjustment is required to achieve the problem of grinding different parts of the parts, and a reversing grinding device and grinding method for special-shaped parts are proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Preferably, a feeding mechanism is provided on the surface of the base, and a first inclined plate is provided on the side of the feeding mechanism, a mounting plate is fixedly connected to the side of the first inclined plate located on the surface of the base, and a fixing mechanism is provided on the surface of the mounting plate.

[0008] Preferably, two groups of the limiting plates are symmetrically arranged about the center of the moving disk, the limiting plates are of "U"-shaped design, and the thickness of the moving disk is smaller than the inner hollow portion of the limiting plates.

[0009] Preferably, the driven rod is arranged at the center point of the connecting shaft, and the driven rod is fixedly connected to the rotating shaft. The driven rod drives the rotating shaft through the connecting shaft to form a rotating structure.

[0010] Preferably, the blanking mechanism includes a handle, a transmission block, a movable rod, a force-bearing rod, a rotating plate, a rotating rod, a driven plate, a rotating wheel, a moving block, a force-bearing block, and a connecting plate. The handle is arranged on the top of the base, and a transmission block is fixedly connected to the side of the handle. The movable rod penetrates through the inside of the transmission block, and the force-bearing rod penetrates through the side of the movable rod. Rotating plates are arranged on both sides of the force-bearing rod, and the rotating rod penetrates through the inside of the two rotating plates. A driven plate is fixedly connected to the side of the rotating rod, and a rotating wheel is rotatably connected to the inner wall of the driven plate. A force-bearing block is movably connected to the tail of the rotating wheel, and a connecting plate is rotatably connected to the inside of the force-bearing block. A moving block is rotatably connected to the surface of the connecting plate.

[0011] Preferably, the connection point between the movable rod and the transmission block is located at the center point of the transmission block, and the included angle between the movable rod and the transmission block is 90°. The movable rod drives the rotating rod through the transmission block to form a rotating structure.

[0012] Preferably, the connection point between the rotating wheel and the driven plate deviates from the center point of the driven plate, and the connection mode between the rotating wheel and the force-bearing block is a ball rotation connection. The force-bearing block drives the moving block to form a sliding structure at the bottom of the first inclined plate through the connecting plate.

[0013] Preferably, the fixing mechanism includes a rotating disk, a convex rod, a push rod, a second inclined plate, a push block, a transmission rod, an elastic clamp, a connecting rod, and an elastic block. The rotating disk is arranged on the top of the base, and a convex rod is fixedly connected to the top of the rotating disk. The push rod is slidably connected to the surface of the convex rod, and the second inclined plate is slidably connected to the side of the push rod. The push block is rotatably connected to the bottom of the second inclined plate, and the transmission rod is rotatably connected to the left side of the push block. The elastic clamp is rotatably connected to the side of the transmission rod. The connecting rod is rotatably connected to the inner wall of the push block, and the elastic block is rotatably connected to the surface of the connecting rod.

[0014] Preferably, the push rod is of a "T" - shaped structure. The connection points between the second inclined plate and the connecting rod and the push block are at the same point, and the push block drives the elastic clamp to form a sliding structure through the second inclined plate.

[0015] This solution also provides a grinding method for a special-shaped part commutation grinding device, including the following steps:

[0016] S1. First, perform the workpiece fixing operation. Place the part to be processed between two sets of elastic clamps. Then, control the rotating disk to rotate. Since the convex rod deviates from the center of the rotating disk and the convex rod is embedded inside the push rod, the push rod will apply a thrust to the second inclined plate as the convex rod rotates. Because the push rod is slidably connected to the second inclined plate, when the second inclined plate receives the thrust from the push rod, it will start to tilt and apply a thrust to the push block, causing the push block to push the elastic clamp to slide through the transmission rod. Since the clamping point of the elastic clamp is designed to be retractable, it can fit well with various parts of the special-shaped part and clamp it better.

[0017] S2. Next, control the part to turn. After the part is fixed by the elastic clamp, then use the grinding device to grind it. In order to enable all parts of the part to be ground, at this time, the part needs to be reversed. First, adjust the moving disk to an inclined state. Then, drive the moving rod to rotate through the motor. The moving rod will drive the moving disk to rotate through the connecting block. Since the moving disk is inclined with respect to the limiting plate, when the moving disk rotates, it will drive the driven rod to rotate through the connecting shaft. Subsequently, the rotating shaft fixed to the driven rod will rotate accordingly, and the purpose of reversing the workpiece for processing is achieved by driving the mounting plate to rotate slightly. When it is necessary to adjust the inclination amplitude of the mounting plate, rotate the screw rod so that it drives the moving rod to move downward through the embedded disk. Then, the moving rod will drive the moving disk to move downward. The moving disk will make the inclination angle smaller under the action of the limiting plate. Subsequently, the rotation angle of the driven rod driven by the limiting plate will also become smaller.

[0018] S3. Finally, realize the unloading operation. When the part is polished, loosen the part through the elastic clamp. The part will fall on the first inclined plate. Then, manually drive the handle to rotate. Since the movable rod deviates from the midpoint of the transmission block, the movable rod will start to slide on the surface of the stress rod as the transmission block rotates and reciprocally expand and contract inside the transmission block. The stress rod will drive the rotating plate and the rotating rod to rotate around the connection point with the base as the movable rod slides. Subsequently, the rotating rod will drive the driven plate to rotate. Since the rotating wheel deviates from the center point of the driven plate, when the driven plate rotates, it will apply a pushing and pulling force to the stress block through the rotating wheel, causing the stress block to drive the moving block to slide at the bottom of the first inclined plate through the connecting plate. When the moving block moves to the right, the first inclined plate will tilt around the connection point with the base, and the part on its surface will slide down accordingly, realizing the unloading.

[0019] Compared with the prior art, the present invention provides a reversing and grinding device for special-shaped parts, having the following beneficial effects:

[0020] 1. The special-shaped part commutation grinding device, by setting a push rod, since the push rod is slidably connected to the second inclined plate, when the second inclined plate receives the thrust from the push rod, it will start to tilt and apply a thrust to the push block, so that the push block drives the elastic clamp to slide through the transmission rod. Since the clamping point of the elastic clamp is designed to be retractable, it can fit well with various parts of the special-shaped part and clamp it better.

[0021] 2. The special-shaped part commutation grinding device, by setting a moving disk, since the moving disk is inclined with respect to the limiting plate, when the moving disk rotates, it will drive the driven rod to rotate through the connecting shaft. Subsequently, the rotating shaft fixed to the driven rod will rotate accordingly, and the purpose of workpiece commutation processing is achieved by driving the mounting plate to rotate slightly. When it is necessary to adjust the inclination amplitude of the mounting plate, rotate the screw rod so that it drives the moving rod to move downward through the embedded disk.

[0022] 3. By setting an active rod, since the active rod deviates from the midpoint of the transmission block, the active rod will start to slide on the surface of the stress rod as the transmission block rotates and reciprocally expand and contract inside the transmission block. The stress rod will drive the rotating plate and the rotating rod to rotate around the connection point with the base as the active rod slides. Subsequently, the rotating rod will drive the driven plate to rotate, applying power to the movement of the stress block.

[0023] 4. Through the rotating wheel, since the rotating wheel is set deviating from the center point of the driven plate, when the driven plate rotates, it will apply a pushing and pulling force to the stress block through the rotating wheel, so that the stress block drives the moving block to slide at the bottom of the first inclined plate through the connecting plate. When the moving block moves to the right, the first inclined plate will tilt around the connection point with the base, and the parts on its surface will slide down accordingly, realizing blanking.

[0024] 5. The special-shaped part commutation grinding device has high practicability. When in use, it can clamp special-shaped parts with different shapes through the control of the elastic clamp to assist in grinding. When grinding, the parts can be commuted by controlling the left and right rotation of the mounting plate, which is convenient for processing the parts from different orientations.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0035] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0036] Refer to Figure 1-8, A commutation grinding device for special-shaped parts, including a base 1. A support column 2 is fixedly connected to the top of the base 1, and a moving rod 3 passes through the top of the support column 2. An adapter block 4 is rotatably connected to the inner wall of the moving rod 3, and a moving disk 5 is fixedly connected to the bottom of the adapter block 4. A limiting plate 6 is attached to the surface of the moving disk 5, and an adapter shaft 7 is rotatably connected to the side of the limiting plate 6. A driven rod 8 is rotatably connected to the surface of the adapter shaft 7. An embedding disk 9 is embedded in the surface of the moving rod 3, and a lead screw 10 passing through the support column 2 is fixedly connected to the bottom of the embedding disk 9.

[0037] Further, a blanking mechanism 11 is arranged on the surface of the base 1, and a first inclined plate 12 is arranged on the side of the blanking mechanism 11. An installation plate 13 is fixedly connected to the surface of the base 1 on the side of the first inclined plate 12, and a fixing mechanism 14 is arranged on the surface of the installation plate 13;

[0038] Further, two groups of limiting plates 6 are symmetrically arranged about the center of the moving disk 5. The limiting plate 6 is designed in a "U" shape, and the thickness of the moving disk 5 is smaller than the inner hollow part of the limiting plate 6. Since the moving disk 5 is inclined with respect to the limiting plate 6, when the moving disk 5 rotates, it will drive the driven rod 8 to rotate through the adapter shaft 7. Subsequently, the rotating shaft 15 fixed to the driven rod 8 will rotate accordingly, and the purpose of workpiece commutation processing is achieved by driving the installation plate 13 to rotate slightly;

[0039] Further, the driven rod 8 is arranged at the center point of the adapter shaft 7, and the driven rod 8 is fixedly connected to the rotating shaft 15. The driven rod 8 drives the rotating shaft 15 to form a rotating structure through the adapter shaft 7. When it is necessary to adjust the inclination amplitude of the installation plate 13, rotate the lead screw 10 to drive the moving rod 3 to move downward through the embedding disk 9. Subsequently, the moving rod 3 will drive the moving disk 5 to move downward, and the moving disk 5 will make the inclination angle smaller under the action of the limiting plate 6. Subsequently, the rotation angle of the limiting plate 6 driving the driven rod 8 will also become smaller;

[0040] Furthermore, the blanking mechanism 11 includes a handle 1101, a transmission block 1102, a movable rod 1103, a force-receiving rod 1104, a rotating plate 1105, a rotating rod 1106, a driven plate 1107, a rotating wheel 1108, a moving block 1109, a force-receiving block 1110, and a connecting plate 1111. The handle 1101 is arranged on the top of the base 1, and a transmission block 1102 is fixedly connected to the side surface of the handle 1101. A movable rod 1103 penetrates through the inside of the transmission block 1102, and a force-receiving rod 1104 penetrates through the side surface of the movable rod 1103. Rotating plates 1105 are arranged on both sides of the force-receiving rod 1104, and a rotating rod 1106 penetrates through the inside of the two rotating plates 1105. A driven plate 1107 is fixedly connected to the side surface of the rotating rod 1106, and a rotating wheel 1108 is rotatably connected to the inner wall of the driven plate 1107. The tail of the rotating wheel 1108 is movably connected to a force-receiving block 1110, and a connecting plate 1111 is rotatably connected to the inside of the force-receiving block 1110. A moving block 1109 is rotatably connected to the surface of the connecting plate 1111. By providing the blanking mechanism 11, the shaped parts after grinding can slide down from the surface of the first inclined plate 12, realizing automatic material discharging. There is no need for manual removal of the ground parts from the equipment, further improving the automation performance of the equipment;

[0041] Furthermore, the connection point between the movable rod 1103 and the transmission block 1102 is located at the center point of the transmission block 1102, and the included angle between the movable rod 1103 and the transmission block 1102 is 90°. The movable rod 1103 drives the rotating rod 1106 through the transmission block 1102 to form a rotating structure. Since the movable rod 1103 deviates from the midpoint of the transmission block 1102, the movable rod 1103 will start to slide on the surface of the force-receiving rod 1104 as the transmission block 1102 rotates and reciprocally expand and contract inside the transmission block 1102;

[0042] Furthermore, the connection point between the rotating wheel 1108 and the driven plate 1107 deviates from the center point of the driven plate 1107, and the connection mode between the rotating wheel 1108 and the force-receiving block 1110 is a ball rotation connection. The force-receiving block 1110 drives the moving block 1109 through the connecting plate 1111 to form a sliding structure at the bottom of the first inclined plate 12. Since the rotating wheel 1108 is arranged deviating from the center point of the driven plate 1107, when the driven plate 1107 rotates, a pushing and pulling force will be applied to the force-receiving block 1110 through the rotating wheel 1108, causing the force-receiving block 1110 to drive the moving block 1109 to slide at the bottom of the first inclined plate 12 through the connecting plate 1111;

[0043] Furthermore, the fixing mechanism 14 includes a rotating disk 1401, a convex rod 1402, a push rod 1403, a second inclined plate 1404, a push block 1405, a transmission rod 1406, an elastic clamp 1407, a connecting rod 1408 and an elastic block 1409. The rotating disk 1401 is arranged on the top of the base 1, and a convex rod 1402 is fixedly connected to the top of the rotating disk 1401. The surface of the convex rod 1402 is slidably connected with the push rod 1403, and the side surface of the push rod 1403 is slidably connected with the second inclined plate 1404. The bottom of the second inclined plate 1404 is rotatably connected with the push block 1405, and the left side of the push block 1405 is rotatably connected with the transmission rod 1406. The side surface of the transmission rod 1406 is rotatably connected with the elastic clamp 1407. The inner wall of the push block 1405 is rotatably connected with the connecting rod 1408, and the surface of the connecting rod 1408 is rotatably connected with the elastic block 1409. By arranging the fixing mechanism 14, the special-shaped part can be fixed during processing, and the clamping points of the elastic clamp 1407 are designed to be telescopic, so that it can better fit with various parts of the special-shaped part;

[0044] Furthermore, the push rod 1403 is of a "T" - shaped structure. The connection points of the second inclined plate 1404 and the connecting rod 1408 with the push block 1405 are at the same point, and the push block 1405 drives the elastic clamp 1407 to form a sliding structure through the second inclined plate 1404. Because the push rod 1403 and the second inclined plate 1404 are slidably connected, when the second inclined plate 1404 receives the thrust from the push rod 1403, it will start to tilt and exert a thrust on the push block 1405, so that the push block 1405 pushes the elastic clamp 1407 to slide through the transmission rod 1406.

[0045] This embodiment also provides a usage plan for the special-shaped part commutation grinding device. Using the above device, it includes the following steps:

[0046] S1. First, perform the workpiece fixing operation. Place the part to be processed between the two elastic clamps 1407, and then control the rotation of the rotating disk 1401. Since the convex rod 1402 is designed to deviate from the center of the rotating disk 1401 and the convex rod 1402 is embedded in the push rod 1403, the push rod 1403 will exert a thrust on the second inclined plate 1404 as the convex rod 1402 rotates. Because the push rod 1403 and the second inclined plate 1404 are slidably connected, when the second inclined plate 1404 receives the thrust from the push rod 1403, it will start to tilt and exert a thrust on the push block 1405, so that the push block 1405 pushes the elastic clamp 1407 to slide through the transmission rod 1406. Since the clamping points of the elastic clamp 1407 are designed to be retractable, it can fit well with various parts of the special-shaped part and clamp it better.

[0047] S2. Next, control the part to turn. After the part is fixed by the elastic fixture 1407, it is then polished by a polishing device. In order to ensure that all parts of the part can be polished, the part needs to be reversed at this time. First, adjust the moving disk 5 to an inclined state, and then drive the moving rod 3 to rotate through the motor. The moving rod 3 will drive the moving disk 5 to rotate through the connecting block 4. Since the moving disk 5 is inclined with respect to the limiting plate 6, when the moving disk 5 rotates, it will drive the driven rod 8 to rotate through the connecting shaft 7. Subsequently, the rotating shaft 15 fixed to the driven rod 8 will rotate accordingly, and the purpose of workpiece reverse machining is achieved by driving the mounting plate 13 to rotate slightly. When it is necessary to adjust the inclination amplitude of the mounting plate 13, rotate the screw rod 10 so that it drives the moving rod 3 to move downward through the embedding disk 9. Subsequently, the moving rod 3 will drive the moving disk 5 to move downward. The moving disk 5 will make the inclination angle smaller under the action of the limiting plate 6. Subsequently, the rotation angle of the driven rod 8 driven by the limiting plate 6 will also become smaller.

[0048] S3. Finally, realize the unloading operation. When the part is polished, loosen the part through the elastic fixture 1407. The part will fall on the first inclined plate 12. Subsequently, manually drive the handle 1101 to rotate. Since the movable rod 1103 deviates from the midpoint of the transmission block 1102, the movable rod 1103 will start to slide on the surface of the force-bearing rod 1104 as the transmission block 1102 rotates and reciprocally expand and contract inside the transmission block 1102. The force-bearing rod 1104 will drive the rotating plate 1105 and the rotating rod 1106 to rotate around the connection point with the base 1 as the movable rod 1103 slides. Subsequently, the rotating rod 1106 will drive the driven plate 1107 to rotate. Since the rotating wheel 1108 deviates from the center point of the driven plate 1107, when the driven plate 1107 rotates, it will apply a pushing and pulling force to the force-bearing block 1110 through the rotating wheel 1108, so that the force-bearing block 1110 drives the moving block 1109 to slide at the bottom of the first inclined plate 12 through the connecting plate 1111. When the moving block 1109 moves to the right, the first inclined plate 12 will tilt around the connection point with the base 1, and the parts on its surface will slide down accordingly, realizing the unloading.

[0049] The working principle of the present invention is as follows: When using this device, first, perform the workpiece fixing operation. Place the part to be processed between two sets of elastic clamps 1407. Subsequently, control the rotation of the rotating disk 1401. Since the convex rod 1402 is designed to deviate from the center of the rotating disk 1401 and the convex rod 1402 is embedded inside the push rod 1403, the push rod 1403 will exert a thrust on the second inclined plate 1404 as the convex rod 1402 rotates. Because the push rod 1403 is in a sliding connection with the second inclined plate 1404, when the second inclined plate 1404 receives the thrust from the push rod 1403, it will start to tilt and exert a thrust on the push block 1405, causing the push block 1405 to push the elastic clamp 1407 to slide through the transmission rod 1406. Since the clamping points of the elastic clamp 1407 are designed to be retractable, it can fit well with various parts of the special-shaped part and better clamp it.

[0050] Next, control the rotation of the part. After the part is fixed by the elastic clamp 1407, then use the grinding equipment to grind it. In order to enable all parts of the part to be ground, at this time, it is necessary to reverse the part. First, adjust the moving disk 5 to an inclined state, and then drive the moving rod 3 to rotate through the motor. The moving rod 3 will drive the moving disk 5 to rotate through the connecting block 4. Since the moving disk 5 is inclined with respect to the limiting plate 6, when the moving disk 5 rotates, it will drive the driven rod 8 to rotate through the connecting shaft 7. Subsequently, the rotating shaft 15 fixed to the driven rod 8 will rotate accordingly, and the purpose of reversing the workpiece for processing is achieved by driving the mounting plate 13 to rotate slightly. When it is necessary to adjust the inclination amplitude of the mounting plate 13, rotate the screw rod 10 so that it drives the moving rod 3 to move downward through the embedding disk 9. Subsequently, the moving rod 3 will drive the moving disk 5 to move downward, and the moving disk 5 will make the inclination angle smaller under the action of the limiting plate 6. Subsequently, the rotation angle of the driven rod 8 driven by the limiting plate 6 will also become smaller.

[0051] Finally, the material discharging operation is realized. After the part is polished, the elastic clamp 1407 releases the part, and the part will fall on the first inclined plate 12. Then, manually drive the handle 1101 to rotate. Since the movable rod 1103 deviates from the midpoint of the transmission block 1102, the movable rod 1103 will start to slide on the surface of the stress rod 1104 as the transmission block 1102 rotates, and reciprocally extend and retract inside the transmission block 1102. The stress rod 1104 will drive the rotating plate 1105 and the rotating rod 1106 to rotate around the connection point with the base 1 as the movable rod 1103 slides. Then, the rotating rod 1106 will drive the driven plate 1107 to rotate. Since the rotating wheel 1108 is arranged deviating from the center point of the driven plate 1107, when the driven plate 1107 rotates, it will apply a pushing and pulling force to the stress block 1110 through the rotating wheel 1108, so that the stress block 1110 drives the moving block 1109 to slide at the bottom of the first inclined plate 12 through the connecting plate 1111. When the moving block 1109 moves to the right, the first inclined plate 12 will tilt around the connection point with the base 1, and the parts on its surface will slide down accordingly, realizing the material discharging.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.

5. A commutation grinding device according to claim 4, characterized in that: The push rod (1403) is of a "T" - shaped structure. The connection points of the second inclined plate (1404) and the connecting rod (1408) with the push block (1405) are at the same point, and the push block (1405) drives the elastic clamp (1407) through the second inclined plate (1404) to form a sliding structure.

6. A grinding method of a commutation grinding device according to claim 5, characterized in that, including the following steps: S1. First, perform the operation of fixing the special-shaped part. Place the special-shaped part to be processed between two groups of elastic clamps (1407). Then, control the rotation of the rotating disk (1401). Since the convex rod (1402) is designed to deviate from the center of the rotating disk (1401) and the convex rod (1402) is embedded inside the push rod (1403), the push rod (1403) will exert a thrust on the second inclined plate (1404) as the convex rod (1402) rotates. Because the push rod (1403) is slidably connected to the second inclined plate (1404), when the second inclined plate (1404) receives the thrust from the push rod (1403), it will start to tilt and exert a thrust on the push block (1405), causing the push block (1405) to push the elastic clamp (1407) to slide through the transmission rod (1406). Since the clamping points of the elastic clamp (1407) are designed to be retractable, it can fit well with all parts of the special-shaped part and better clamp it. S2. Next, control the rotation of the special-shaped part. After the special-shaped part is fixed by the elastic clamp (1407), it is then polished by a polishing device. In order to polish all parts of the special-shaped part, the special-shaped part needs to be reversed at this time. First, adjust the moving disk (5) to an inclined state. Then, drive the moving rod (3) to rotate through the motor. The moving rod (3) will drive the moving disk (5) to rotate through the connecting block (4). Since the moving disk (5) is inclined with respect to the limiting plate (6), when the moving disk (5) rotates, it will drive the driven rod (8) to rotate through the connecting shaft (7). Subsequently, the rotating shaft (15) fixed to the driven rod (8) will rotate accordingly, and the purpose of reversing the processing of the special-shaped part is achieved by driving the mounting plate (13) to rotate slightly. When it is necessary to adjust the inclination amplitude of the mounting plate (13), rotate the screw rod (10) so that it drives the moving rod (3) to move downward through the embedded disk (9). Then, the moving rod (3) will drive the moving disk (5) to move downward. The moving disk (5) will make the inclination angle smaller under the action of the limiting plate (6). Subsequently, the rotation angle of the driven rod (8) driven by the limiting plate (6) will also become smaller. S3. Finally, the unloading operation is realized. When the special-shaped part is polished, the elastic fixture (1407) releases the special-shaped part, and the special-shaped part will fall on the first inclined plate (12). Then, manually rotate the handle (1101). Since the movable rod (1103) deviates from the midpoint of the transmission block (1102), the movable rod (1103) will start to slide on the surface of the stress rod (1104) and reciprocally expand and contract inside the transmission block (1102) as the transmission block (1102) rotates. The stress rod (1104) will drive the rotating plate (1105) and the rotating rod (1106) to rotate around the connection point with the base (1) as the movable rod (1103) slides. Then, the rotating rod (1106) will drive the driven plate (1107) to rotate. Since the rotating wheel (1108) is arranged deviating from the center point of the driven plate (1107), when the driven plate (1107) rotates, it will apply a pushing and pulling force to the stress block (1110) through the rotating wheel (1108), so that the stress block (1110) drives the moving block (1109) to slide at the bottom of the first inclined plate (12) through the connecting plate (1111). When the moving block (1109) moves to the right, the first inclined plate (12) will tilt around the connection point with the base (1), and the special-shaped part on its surface will slide down accordingly, realizing the material unloading.
