Description

Technical Field

[0001] This invention belongs to the field of mechanical parts processing technology, and relates to a chamfering device for the opening of mechanical parts. Background Technology

[0002] Mechanical parts are the basic components that make up machinery; they are inseparable individual parts that make up machinery and machines. Mechanical parts often require holes. After drilling, in order to reduce stress concentration and prevent cracks or breakage during use, the hole openings need to be chamfered, hence the use of chamfering devices.

[0003] A fully automatic gear inner hole chamfering system and chamfering method disclosed in Chinese patent CN117139741B includes a conveyor for transporting gears. After processing, the gears move on the conveyor and are transported to the next processing step such as quality inspection. This application chamfers the gears on the conveyor and puts them back on the conveyor. It also includes a chamfering mechanism and a clamping and lifting mechanism that clamps the gears from both sides of the conveyor and drives the gears to rise and fall.

[0004] This internal chamfering system chamfers parts on a conveyor, after which the parts are placed back on the conveyor for the next process. However, when parts undergo multi-processing, space constraints often require moving them to different conveyor belts. This necessitates workers moving the chamfered workpieces to the next conveyor belt, increasing workload and reducing chamfering efficiency. Furthermore, when chamfering is done using a rotating scraper, the scraper wears down over time, requiring regular inspection. Failure to inspect it promptly can result in burrs or unevenness at the chamfered area.

[0005] To address the aforementioned problems, this invention proposes a chamfering device for the openings of machined mechanical parts. Summary of the Invention

[0006] To address the problems existing in the background art, the present invention proposes a chamfering device for machining the openings of mechanical parts.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes a first conveyor belt and a second conveyor belt, a second motor is arranged above the first conveyor belt and the second conveyor belt, and a cutter is fixedly connected to the output shaft of the second motor; A rotating shaft is rotatably arranged between the first conveyor belt and the second conveyor belt. A rotating plate is rotatably sleeved on the rotating shaft. A stop block is fixedly connected to the outer surface of the rotating shaft. A fixing block is fixedly connected to the inner wall of the connection between the rotating plate and the rotating shaft. The stop block and the fixing block abut against each other. The rotating plate has clamping holes, and four clamping members are evenly slidably arranged on the first plane of the rotating plate. The four clamping members are arranged in a circumferential array about the clamping holes. A rotating ring is rotatably connected to the second plane of the rotating plate by a first spring. The rotating ring is connected to the rotating shaft by a pull rope. Four driving members are evenly arranged on the rotating ring. The driving members correspond one-to-one with the clamping members. When the rotating shaft drives the rotating ring to rotate by the pull rope, the four driving members drive the four clamping members to slide towards each other or away from each other on the rotating plate.

[0008] Furthermore, a mounting frame is fixedly connected to the side of the first conveyor belt near the second conveyor belt. Two side plates are symmetrically fixedly arranged on the top of the mounting frame. A rotating shaft is rotatably connected between the two side plates. A first motor is fixedly connected to one side of one of the side plates, and the first motor drives the rotating shaft to rotate.

[0009] Furthermore, the diameters at both ends of the rotating shaft are larger than the diameter in the middle of the rotating shaft. The rotating plate is slidably engaged with the two ends of the rotating shaft with larger diameters. The stop block is fixedly connected to the outer surface of the section of the rotating shaft with smaller diameter in the middle. One end of the stop block is fixedly connected to the end of the rotating shaft with larger diameter. There is a gap between the other end of the stop block and the other end of the rotating shaft with larger diameter. One end of the fixing block is flush with one end of the stop block, and the other end of the fixing block is flush with the other end of the stop block.

[0010] Furthermore, the end of the pull rope fixed to the rotating shaft is located within the gap between the end of the stop block and the end of the rotating shaft with a larger diameter, and the pull rope can be wound around the gap between the end of the rotating shaft and the end of the stop block; a pull rod is fixedly connected to the outer surface of the rotating ring; The rotating plate has a channel that connects to the outer surface of the rotating shaft with a smaller diameter. The pull rope is movably disposed in the channel, and the other end of the pull rope is fixedly connected to one side of the pull rod.

[0011] Furthermore, four arc-shaped limiting grooves are evenly provided on the rotating plate, and a limiting block is slidably connected inside each limiting groove. A first spring is fixedly connected between the limiting block and the end face of the limiting groove. The four first springs and the four limiting grooves are all distributed in a circumferential array about the clamping hole. The rotating ring is fixedly connected to the bottom of the four limiting blocks.

[0012] Furthermore, a sliding groove is provided on the first plane of the rotating plate at each clamping member. The clamping member includes an arc-shaped clamping plate, which is movably disposed in the clamping hole. A vertical plate is fixedly connected to the top of the clamping plate, and a clamping rod is fixedly connected to the top of the vertical plate. The clamping rod is horizontally arranged, and a push plate is fixedly connected to the end of the clamping rod away from the vertical plate. A slider is fixedly connected to the bottom of the push plate, and the slider is slidably connected in the corresponding sliding groove. On the first plane of the rotating plate, a support plate is fixedly connected to the end of each slide groove, and the clamping rod slides through the corresponding support plate.

[0013] Furthermore, each of the clamping rods is fitted with a pressure sensor, which is fixedly connected to one side of the corresponding support plate. A second spring is fixedly connected between each pressure sensor and the corresponding push plate, and the second spring is fitted on the corresponding clamping rod.

[0014] Furthermore, the driving component includes four push grooves, each push groove being a rounded rectangular groove. The four push grooves are evenly distributed in a circle on the rotating ring, and each push groove corresponds to a sliding groove. The symmetry line of the push groove does not pass through the center of the clamping hole. Each slider has a sliding rod fixedly connected to its bottom end, and the sliding rod is slidably connected to the corresponding push groove.

[0015] Furthermore, the top of the first conveyor belt is provided with several annular workpieces at intervals, the diameter of the clamping holes is larger than the outer surface diameter of the workpieces, and the four clamping plates are all in contact with the outer surface of the workpieces.

[0016] Furthermore, an electric slide rail is fixedly installed above the first conveyor belt, a portion of which is located directly above the first and second conveyor belts. An electric telescopic rod is slidably installed at the bottom of the electric slide rail, and an installation plate is fixedly connected to the output end of the electric telescopic rod. A second motor is fixedly connected to one side of the installation plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The chamfering device for the hole of the machining machine parts is equipped with a rotating plate. One end of the rotating plate is rotatably positioned between the first conveyor belt and the second conveyor belt. When the rotating shaft is driven to rotate by the first motor, the rotating shaft drives the fixed block to rotate through the stop block, causing the rotating plate to rotate. This directly moves the workpiece on the first conveyor belt to the second conveyor belt. After the workpiece is moved, it can be chamfered directly on the second conveyor belt without having to move the workpiece separately, thus reducing workload and improving work efficiency.

[0018] 2. The chamfering device for the hole of the machining part is equipped with four clamping plates. When the rotating shaft drives the stop to rotate, it pulls one end of the pull rope, which is wound around the rotating shaft. The pull rope pulls the pull rod, causing the rotating ring to rotate. When the rotating ring rotates, it drives the sliding rod to move, which in turn drives the clamping plates to move. The four clamping plates cooperate to clamp and fix the workpiece. After clamping, the rotating shaft continues to rotate, which drives the fixed block to rotate through the stop, which in turn drives the rotating plate to rotate the workpiece. The clamping and movement of the workpiece is achieved through the first motor. The operation is simple.

[0019] 3. The chamfering device for the hole of the machining machine parts is equipped with four clamping plates. When the rotating ring rotates, it will drive the push groove to rotate. The push groove pushes the corresponding slide rod, which drives the four clamping plates to move. Since the four clamping plates move the same distance, when one of the clamping plates contacts the workpiece, it will push the workpiece to move until all four clamping plates contact the workpiece and work together to fix the workpiece, so that the workpiece is subjected to uniform clamping force from the four clamping plates.

[0020] 4. The chamfering device for the orifice of the machining machine parts is equipped with pressure sensors. When the sliding rod is moved, the push plate drives the clamping rod to move. The clamping rod slides on the support plate, which compresses the second spring. The second spring transmits the force to the pressure sensors, and the pressure values ​​of the four pressure sensors are equal. Therefore, when the cutter is chamfering, it will squeeze the workpiece. The pressure sensor values ​​can detect the stress on different parts of the workpiece based on the changes in the pressure sensor values. Then, by comparing the values, the wear condition of the cutter can be judged, so as to replace the cutter in time and reduce the occurrence of burrs or unevenness at the chamfer.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-15 As shown, the technical solution adopted by the present invention is as follows: a chamfering device for processing machine parts, comprising a first conveyor belt 1 and a second conveyor belt 24, with a rotating shaft 5 rotatably arranged between the first conveyor belt 1 and the second conveyor belt 24. The conveyor belt mainly consists of a conveyor belt, a drive device, a tensioning device, idlers, a support frame, etc., and the drive device causes the conveyor belt to move continuously to transport materials. The conveyor belt is an existing product.

[0025] A mounting frame 3 is fixedly connected to the side of the first conveyor belt 1 near the second conveyor belt 24. Two side plates are symmetrically fixed to the top of the mounting frame 3. A rotating shaft 5 is rotatably connected between the two side plates. A first motor 4 is fixedly connected to one side of one of the side plates, and the first motor 4 drives the rotating shaft 5 to rotate. The output shaft of the first motor 4 rotates through the side plate and is fixedly connected to the end of the rotating shaft 5. The first motor 4 drives the rotating shaft 5 to rotate through the output shaft.

[0026] A rotating plate 7 is rotatably mounted on the rotating shaft 5, with its two ends slidingly engaged with corresponding side plates. A stop block 6 is fixedly connected to the outer surface of the rotating shaft 5, and a fixing block 8 is fixedly connected to the inner wall of the connection between the rotating plate 7 and the rotating shaft 5, with the stop block 6 and the fixing block 8 abutting against each other. When the rotating shaft 5 drives the stop block 6 to rotate, it pushes the fixing block 8, thereby driving the rotating plate 7 to rotate.

[0027] The two side plates that are close to each other are provided with an anti-slip coating, and the rotating plate 7 is also provided with an anti-slip coating on the side that slides with the two side plates. The anti-slip coating positions the rotating plate 7 between the two side plates, and the rotating plate 7 can only move when the stop block 6 pushes the fixing block 8.

[0028] The diameters at both ends of the rotating shaft 5 are larger than the diameter at the middle of the rotating shaft 5, and the rotating plate 7 slides with the two ends of the rotating shaft 5 with larger diameters. This creates a gap between the smaller diameter portion of the middle of the rotating shaft 5 and the rotating plate 7.

[0029] A stop block 6 is fixedly connected to the outer surface of the smaller diameter section of the rotating shaft 5, and the stop block 6 is arranged along the axial direction of the rotating shaft 5. One end of the stop block 6 is fixedly connected to the larger diameter end of the rotating shaft 5, and there is a gap between the other end of the stop block 6 and the other larger diameter end of the rotating shaft 5. One end of the fixing block 8 is flush with one end of the stop block 6, and the other end of the fixing block 8 is also flush with the other end of the stop block 6. This ensures that there is also a gap between one end of the fixing block 8 and the other larger diameter end of the rotating shaft 5.

[0030] The rotating plate 7 has clamping holes 21. When the rotating plate 7 rotates to the top of the first conveyor belt 1, the clamping holes 21 are located directly above the first conveyor belt 1. When the rotating plate 7 rotates to the top of the second conveyor belt 24, the clamping holes 21 are located directly above the second conveyor belt 24.

[0031] Four clamping members are evenly slidably arranged on the first plane of the rotating plate 7, and the four clamping members are arranged in a circumferential array about the clamping hole 21.

[0032] The top of the first conveyor belt 1 is provided with several annular workpieces 2 at intervals. The diameter of the clamping hole 21 is larger than the outer surface diameter of the workpiece 2. After the rotating plate 7 rotates so that the clamping hole 21 is outside the workpiece 2, the workpiece 2 is fixed by the cooperation of four clamping members.

[0033] A rotating ring 11 is rotatably connected to the second plane of the rotating plate 7 via a first spring 14.

[0034] Four arc-shaped limiting grooves 13 are evenly distributed on the rotating plate 7. Each limiting groove 13 has a limiting block 12 slidably connected inside. A first spring 14 is fixedly connected between the limiting block 12 and the end face of the limiting groove 13. In the initial state, the first spring 14 pushes the limiting block 12, causing the limiting block 12 to abut against the end of the limiting groove 13. The four first springs 14 and the four limiting grooves 13 are arranged in a circumferential array about the clamping hole 21, facilitating the movement of the four limiting blocks 12 in the same direction.

[0035] The rotating ring 11 is fixedly connected to the bottom of the four limiting blocks 12. The limiting blocks 12 position the rotating ring 11 within the second plane of the rotating plate 7. When the rotating ring 11 rotates, it causes the four limiting blocks 12 to slide within their corresponding limiting grooves 13, compressing the first spring 14. Conversely, the spring force of the first spring 14 can push the rotating ring 11 back to its original position.

[0036] The rotating ring 11 is connected to the rotating shaft 5 via a pull rope 10. When the rotating shaft 5 rotates, it pulls the rotating ring 11 to rotate via the pull rope 10.

[0037] One end of the pull rope 10, which is fixed to the rotating shaft 5, is located within the gap between the end of the stop block 6 and the end of the rotating shaft 5 with the larger diameter. The pull rope 10 can be wound around the gap between the end of the rotating shaft 5 and the end of the stop block 6. When the rotating shaft 5 rotates, the pull rope 10 is wound around the rotating shaft 5, thereby causing the other end of the pull rope 10 to pull the rotating ring 11 to rotate.

[0038] A pull rod 15 is fixedly connected to the outer surface of the rotating ring 11. A clearance groove is provided on the second plane of the rotating plate 7 to allow the pull rod 15 to move.

[0039] A channel 9 is provided on the rotating plate 7. One end of the channel 9 is connected to the outer surface of the rotating shaft 5 with a smaller diameter, and the other end of the channel 9 is connected to the clearance groove. The pull rope 10 is movably disposed in the channel 9, and the other end of the pull rope 10 is fixedly connected to one side of the pull rod 15. Under the action of the first spring 14, the rotating ring 11 is pushed, causing the pull rod 15 to pull one end of the pull rope 10, keeping the pull rope 10 in a taut state.

[0040] A groove 17 is provided on the first plane of the rotating plate 7 at each clamping member. Each clamping member includes an arc-shaped clamping plate 28, which is movably disposed within the clamping hole 21. A vertical plate 25 is fixedly connected to the top of the clamping plate 28, and a clamping rod 23 is fixedly connected to the top of the vertical plate 25. The clamping rod 23 is horizontally arranged and located outside the rotating plate 7. The end face of the clamping rod 23 is flush with the side of the vertical plate 25, and all four clamping plates 28 abut against the outer surface of the workpiece 2. This ensures that when the clamping plates 28 clamp the workpiece 2, the clamping rod 23 and the vertical plate 25 do not contact the workpiece 2. A rubber layer is provided on the side of each of the four clamping plates 28 away from the inner wall of the clamping hole 21. This rubber layer provides cushioning and protection for the workpiece 2, preventing excessive clamping force from damaging its surface.

[0041] A push plate 20 is fixedly connected to the end of the clamping rod 23 away from the upright plate 25. A slider 18 is fixedly connected to the bottom of the push plate 20, and the slider 18 is slidably connected in the corresponding groove 17. The horizontal movement of the clamping plate 28 is positioned by the slider 18 sliding inside the groove 17.

[0042] On the first plane of the rotating plate 7, a support plate 22 is fixedly connected to the end of each slide groove 17, and a clamping rod 23 slides through the corresponding support plate 22. The clamping rod 23 limits the clamping plate 28 in the vertical direction.

[0043] Each clamping rod 23 is fitted with a pressure sensor 27, which is fixedly connected to one side of the corresponding support plate 22. A second spring 26 is fixedly connected between each pressure sensor 27 and the corresponding push plate 20. The second spring 26 is fitted onto the corresponding clamping rod 23. When the clamping rod 23 slides on the support plate 22, the push plate 20 compresses the second spring 26. The end of the second spring 26 pushes the pressure sensor 27, enabling the pressure sensor 27 to sense the pressure signal and convert it into a usable output electrical signal according to a certain rule, thereby displaying the clamping force of the clamping plate 28 on the workpiece 2.

[0044] Four driving components are evenly arranged on the rotating ring 11, and each driving component corresponds to a clamping component. When the rotating shaft 5 drives the rotating ring 11 to rotate via the pull rope 10, the driving components drive the corresponding clamping components to slide. The four driving components drive the four clamping components to slide towards each other or away from each other on the rotating plate 7.

[0045] The driving component includes four push grooves 16, each push groove 16 being a rounded rectangular groove. Specifically, the center of each push groove 16 is rectangular, and both ends are arc-shaped. The four push grooves 16 are evenly distributed circumferentially on the rotating ring 11, with each push groove 16 corresponding to a sliding groove 17. The line of symmetry of each push groove 16 does not pass through the center of the clamping hole 21. That is, there is an included angle between each push groove 16 and its corresponding sliding groove 17.

[0046] Each slider 18 has a fixed sliding rod 19 at its bottom end, and the sliding rod 19 is slidably connected to the corresponding push groove 16. When the rotating ring 11 drives the push groove 16 to rotate, the push groove 16 pushes the corresponding sliding rod 19, causing the slider 18 to slide within the slide groove 17, and the four sliders 18 slide equidistantly. Furthermore, the rotation of the rotating ring 11 drives the four sliders 18 to slide towards or away from each other.

[0047] The top surface of the second conveyor belt 24 is located below the top surface of the first conveyor belt 1. When the rotating plate 7 rotates to the top of the first conveyor belt 1, the rotating plate 7 is in a horizontal state, so that the second plane of the rotating plate 7 contacts the top of the first conveyor belt 1. When the rotating plate 7 rotates to the top of the second conveyor belt 24, the rotating plate 7 is in a horizontal state, so that the first plane of the rotating plate 7 is closer to the top surface of the second conveyor belt 24, at which time the support plate 22 contacts the top of the second conveyor belt 24.

[0048] A second motor 31 is installed above the first conveyor belt 1 and the second conveyor belt 24, and a cutter 32 is fixedly connected to the output shaft of the second motor 31.

[0049] An electric slide rail 29 is fixedly installed above the first conveyor belt 1, with a portion of the electric slide rail 29 located directly above the first conveyor belt 1 and the second conveyor belt 24. The electric slide rail 29 is a mechanical structure driven by an electric motor, and its movement is caused by power supply and control signals. The electric slide rail 29 is an existing product.

[0050] An electric telescopic rod 30 is slidably mounted on the bottom of the electric slide rail 29. When the electric slide rail 29 is running, it drives the electric telescopic rod 30 to move horizontally along the layout direction of the electric slide rail 29. A mounting plate is fixedly connected to the output end of the electric telescopic rod 30. The electric telescopic rod 30 is vertically positioned, and it pushes the mounting plate to move vertically up and down. A second motor 31 is fixedly connected to one side of the mounting plate. The second motor 31 drives the cutter 32 to rotate, causing the cutter 32 to chamfer the opening.

[0051] The cutter 32 consists of several blades. When the cutter 32 rotates to perform chamfering, if one of the blades is worn, it will accelerate the wear of other blades, thereby increasing the consumption of blades.

[0052] Working principle: In the initial state, the second plane of the rotating plate 7 is in contact with the top of the first conveyor belt 1. The clamping hole 21 is located directly above the first conveyor belt 1, and one of the workpieces 2 is located in the clamping hole 21, between the four clamping plates 28. The stop block 6 is in contact with the fixing block 8.

[0053] Start the first motor 4, and the output end of the first motor 4 rotates clockwise. This drives the rotating shaft 5 to rotate, causing the stop block 6 to rotate. The stop block 6 gradually rotates away from the fixed block 8.

[0054] The rotating shaft 5 pulls one end of the pull rope 10, winding the pull rope 10 around the rotating shaft 5. The pull rope 10 moves within the channel 9, while the other end of the pull rope 10 pulls the pull rod 15, causing the pull rod 15 to slide within the relief groove.

[0055] The pull rod 15 will drive the rotating ring 11 to move. Due to the limiting block 12, the rotating ring 11 will rotate in the second plane of the rotating plate 7. The rotating ring 11 will drive the limiting block 12 to slide inside the limiting groove 13, and the limiting block 12 will compress the first spring 14.

[0056] The rotating ring 11 drives the push groove 16 to rotate, and the push groove 16 pushes the slide rod 19 to move when it rotates. The slide rod 19 drives the slider 18 to slide inside the slide groove 17, and the slider 18 drives the push plate 20 to slide on the first plane of the rotating plate 7. This drives the clamping rod 23, the upright plate 25, and the clamping plate 28 to move. The clamping plate 28 moves closer to the outer surface of the workpiece 2, and the clamping rod 23 slides on the support plate 22.

[0057] The push plate 20 compresses the second spring 26, and the other end of the second spring 26 pushes the pressure sensor 27. Until the clamping plate 28 abuts against the outer surface of the workpiece 2, the pressure sensor 27 can detect the clamping force of the clamping plate 28 on the workpiece 2.

[0058] Since the four clamping plates 28 cooperate to fix the workpiece 2, when the four clamping plates 28 move, if one of the clamping plates 28 first contacts the workpiece 2, that clamping plate 28 will push the workpiece 2 to move until all four clamping plates 28 together abut and fix the workpiece 2. This makes the workpiece 2 concentric with the clamping hole 21, so that the workpiece 2 is subjected to uniform force, and at the same time facilitates the subsequent chamfering of the workpiece 2.

[0059] After the four clamping plates 28 clamp the workpiece 2, the stop block 6 will rotate to one side of the fixed block 8.

[0060] The electric telescopic rod 30 is moved by the electric slide rail 29, which drives the second motor 31 and the cutter 32 to move until the cutter 32 is moved directly above the hole on the workpiece 2.

[0061] Start the second motor 31 to rotate the cutter 32, and start the electric telescopic rod 30 to move the second motor 31 and the cutter 32 downward. Move the cutter 32 into the orifice so that the cutter 32 chamfers the orifice.

[0062] During the chamfering process, the pressure sensor 27 can detect the force applied to the workpiece 2. The readings of the four pressure sensors 27 will change during chamfering. If the readings of the four pressure sensors 27 are different, it indicates that the cutter 32 is worn. This allows the operator to replace the cutter 32 in a timely manner, thereby reducing the occurrence of burrs or unevenness at the chamfered area.

[0063] After one side of workpiece 2 is chamfered, the first motor 4 causes the rotating shaft 5 to drive the stop block 6 to continue rotating. The stop block 6 will push the fixed block 8 to rotate together, causing the rotating plate 7 to rotate. At this time, the rotating shaft 5 will no longer be wrapped with the pull rope 10, and will drive the rotating plate 7 to rotate together.

[0064] After the rotating plate 7 reaches a vertical position, it continues to rotate, and the fixed block 8 will be located at the bottom of the stop block 6. Since the pull rope 10 is taut, the rotating shaft 5 will tighten the pull rod 15, preventing the rotating ring 11 from rotating. For the rotating plate 7 to continue rotating downwards independently, the pull rope 10 needs to be wound around the rotating shaft 5; therefore, the rotating plate 7 cannot rotate downwards independently under gravity. Simultaneously, due to the anti-slip coating, the rotating plate 7 also cannot rotate independently.

[0065] The rotating plate 7 rotates until the rotating shaft 5 drives it to the top of the second conveyor belt 24, so that the first plane of the rotating plate 7 is close to the second conveyor belt 24. The support plate 22 contacts the top surface of the second conveyor belt 24, and the rotating plate 7 is in a horizontal state.

[0066] The cutter 32 is moved by the electric slide rail 29, causing it to chamfer the opening on the other side of the workpiece 2. Simultaneously, the force applied to the workpiece 2 can be detected by four pressure sensors 27.

[0067] After the chamfering is completed, the output of the first motor 4 reverses direction, driving the rotating shaft 5 to rotate, causing the stop block 6 to rotate. The stop block 6 gradually rotates away from the fixed block 8.

[0068] When the rotating shaft 5 rotates, it no longer tightens the pull rope 10, causing the wound pull rope 10 to unwind. At this time, the first spring 14 pushes the limiting block 12, which in turn drives the rotating ring 11 to rotate. This causes the pull rod 15 to slide within the relief groove, and the pull rod 15 continues to tighten the pull rope 10. Therefore, under the action of the first spring 14, the pull rope 10 remains in a taut state.

[0069] The rotating ring 11 drives the push groove 16 to rotate, causing the push groove 16 to push the slide rod 19 to move. This causes the slider 18 to slide inside the slide groove 17. The slider 18 drives the clamping rod 23, push plate 20, and clamping plate 28 to move. The push plate 20 slides on the first plane of the rotating plate 7, causing the second spring 26 to extend and the force on the pressure sensor 27 to decrease. This, in turn, causes the clamping plate 28 to move within the clamping hole 21, causing the clamping plate 28 to move away from the workpiece 2.

[0070] After the four clamping plates 28 leave the workpiece 2, the stop block 6 will rotate to one side of the fixed block 8. The first motor 4 drives the rotating shaft 5 to continue rotating the stop block 6, which in turn pushes the fixed block 8, causing the rotating plate 7 to rotate. Due to the anti-slip coating, the stop block 6 will push the fixed block 8 to rotate the clamping hole 21 to the top of the first conveyor belt 1, so as to continue clamping the next workpiece 2.

[0071] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
