Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to a quick clamp for processing automobile parts. Background Art

[0002] Auto parts are the various units that make up the whole car and are a kind of product that serves the car. The car contains a large number of different types of parts. During the assembly process, the parts need to be connected to form the product together. A large number of annular parts are used in automobile assembly, such as piston rings, brake drums, wheel hubs, spokes, flanges, etc. Due to the round outer surface of the annular parts, the stability of the clamping has an important influence on the processing quality of the annular parts.

[0003] The existing clamps for annular accessories are generally a combination of a robotic arm and a multi-point pneumatic gripper. However, when in use, the annular accessories on a conveying device such as a conveyor belt need to be grasped by a self-propelled robotic arm, or the annular accessories need to be manually delivered to the clamp. The former is prone to problems with clamping accuracy and a long clamp positioning time, while the latter has certain operational risks. Therefore, a quick clamp for processing automotive accessories is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing annular accessory clamp needs to be used, either by a self-propelled robotic arm to grab the annular accessory on a conveying device such as a conveyor belt, or by manually delivering the annular accessory to the clamp.

[0006] Furthermore, a linear guide is fixedly installed on the top of the lifting rod, an electric slider is drive-installed on the top of the linear guide, a push frame is fixedly installed on the top of the electric slider, and push rings are fixedly installed on the ends of the two push frames away from each other, and the two push rings are movably connected to the two suspension rods respectively.

[0007] Furthermore, the suspension rods are sleeved with rubber sleeves, and the two rubber sleeves are respectively located inside the two push rings.

[0008] Furthermore, a suspension frame is fixedly installed on the top of the lifting bracket, and a vertically arranged clamping electric push rod is fixedly installed inside the suspension frame. The telescopic end of the clamping electric push rod faces downward and is fixedly installed with a horizontally arranged pressure plate, and two arc-shaped pressure rods are fixedly installed at both ends of the pressure plate, and the four arc-shaped pressure rods are symmetrically distributed on the tops of the two suspension rods.

[0009] Furthermore, balance bars parallel to the pressure plate are provided on both sides of the pressure plate, and two ends of the balance bar are respectively fixedly mounted on the two arc-shaped pressure bars.

[0010] Furthermore, a discharge rack is arranged on the side of the placement and fixing frame facing away from the transfer robot arm, a discharge pipe is fixedly installed on the top of the discharge rack, the discharge pipe is arranged at an angle, one end of the discharge pipe is arranged obliquely upward and a flaring pipe is fixedly installed, the other end of the discharge pipe faces the placement and fixing frame and is provided with a plurality of make way grooves, and the make way grooves are adapted to the lifting hydraulic rod and the arc pressure rod.

[0011] Furthermore, an assembly frame is fixedly installed on the top of the three-finger pneumatic mechanism, and a photoelectric sensor is fixedly installed on the bottom of the assembly frame, and the position of the photoelectric sensor corresponds to the position of the suspension rod.

[0012] Furthermore, blocking plates are fixedly installed on both sides of both ends of the arc-shaped clamping jaw.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention sets a sorting component so that the annular accessories are hung on the sorting component in batches, the three-finger pneumatic mechanism clamps the annular accessories, and the transport robot carries the accessories for transport. By hanging the annular accessories on the upper hanging rod, the annular accessories are kept in a hanging and drooping state and are quickly clamped by the three-finger pneumatic mechanism and the arc-shaped clamping claws. The annular accessories with eccentric weights will automatically rotate downward under the action of their own gravity, so that the annular accessories with irregular structures will also maintain the same posture and orientation, which is convenient for the three-finger pneumatic mechanism to quickly clamp; 2. The present invention provides a push ring so that when the transfer robot arm and the three-finger pneumatic mechanism are clamping and transferring the annular accessories on the hanging rod, if the farthest accessory is clamped, the electric slider on the same side will drive the push ring to push the accessory queue to slide on the hanging rod, so that the empty position of the accessory is replenished, so that the three-finger pneumatic mechanism can clamp the accessory again at the same position when it is reset, thereby greatly shortening the time for positioning the fixture, so that the transfer robot arm and the three-finger pneumatic mechanism can quickly transfer the accessories; 3. The present invention sets a rubber sleeve so that the rubber sleeve is sleeved on the suspension rod. The rubber sleeve can prevent the annular accessory from directly contacting the suspension rod, and prevent the inner ring of the accessory and the suspension rod from sliding relative to each other when the push ring pushes the accessory, causing wear of the two. At the same time, the rubber sleeve can increase the friction resistance of the accessory when it moves on the suspension rod, and effectively prevent the accessory from falling directly from one end of the suspension rod due to excessive inertia when it is pushed by the push ring. 4. The present invention provides an arc-shaped pressure rod, so that after all the annular accessories are hung, the clamping electric push rod drives the pressure plate to press on the top two sides of the annular accessories, forming a three-point clamping of the accessories, so that the accessories are stably clamped on the hanging rod and will not be thrown off from one end of the hanging rod due to the centrifugal force generated by the rotation of the rotating joint. When the three-finger pneumatic mechanism clamps the accessories, the clamping electric push rod drives the arc-shaped pressure rod to reset, thereby releasing the restriction on the accessories; 5. The present invention provides a balance bar so that the balance bars on both sides of the pressure plate can be fixed to one end of a total of four arc-shaped pressure bars on both sides, thereby applying a certain pulling force to the arc-shaped pressure bars, dispersing the loads at both ends of the pressure plate, thereby reducing the bending moment at the connection between the arc-shaped pressure bars and the pressure plate, and preventing the arc-shaped pressure bars from sinking at one end after long-term use, thereby affecting the clamping and limiting effect of the arc-shaped pressure bars on the accessories; 6. The present invention provides a discharge pipe, so that the staff can directly put the annular accessories into the discharge pipe through the flaring pipe. The annular accessories will automatically fall to the bottom of the discharge pipe and hang on the hanging rod, and slide down along the inclined hanging rod, which greatly facilitates the loading operation of the accessories and greatly simplifies the loading operation of the staff. At the same time, the discharge pipe and the flaring pipe enable the staff to maintain a sufficient safety distance from the sorting components, the transfer robot arm, and the processing station, thereby reducing the operation risk; 7. The present invention sets a photoelectric sensor so that when the transfer robot arm drives the three-finger pneumatic mechanism to approach the annular accessory on one end of the suspension rod, the photoelectric sensor moving with the three-finger pneumatic mechanism will sense the position of the accessory in advance, and then monitor and correct the moving trajectory and moving stroke of the three-finger pneumatic mechanism in real time, ensuring that the three arc-shaped clamps can accurately stay on the peripheral side of the annular accessory, ensuring that the three-finger pneumatic mechanism moves into place and does not move excessively, further reducing the positioning time and improving the positioning accuracy; 8. The present invention provides blocking plates so that when the three-finger pneumatic mechanism drives the three arc-shaped claws to clamp the outer ring of the annular accessory, the blocking plates on the front and rear sides of the two ends of the arc-shaped claws will be respectively stuck on the front end surface and the rear end surface of the annular accessory, so that the annular accessory is clamped by the arc-shaped claws while being surrounded by the blocking plate array, effectively preventing the annular accessory and the arc-shaped claws from relative slipping during the process of transporting the accessory by the transport robot arm, which may lead to positioning or clamping failure.

[0019] like Figures 1 to 9 As shown, a quick clamp for processing automobile parts includes a transfer robot arm 1, such as Figure 2 As shown, the driving end of the transfer robot arm 1 is driven by a three-finger pneumatic mechanism 2. Figure 3As shown, the driving end of the three-finger pneumatic mechanism 2 is driven and installed with three evenly distributed arc-shaped clamping claws 3, and a sorting component is provided on one side of the transfer robot arm 1; The sorting component is used to hang the annular accessories in batches on one side of the three-finger pneumatic mechanism 2 so that the three-finger pneumatic mechanism 2 can grab the annular accessories. Figure 1 As shown, the sorting assembly includes a placement fixing frame 4 arranged on one side of the transfer robot arm 1, as shown in FIG. Figure 5 As shown, a rotating joint 5 is rotatably installed on the top of the placement fixing frame 4, a steering gear ring 6 is fixedly sleeved on the top of the rotating joint 5, and a driving motor 7 is fixedly installed on one side of the top of the placement fixing frame 4. In this embodiment, in order to improve the accuracy of the rotating action of the rotating joint 5, the driving motor 7 can adopt a servo motor, and the output shaft of the driving motor 7 is fixedly sleeved with a driving gear 8, and the driving gear 8 is meshed with the steering gear ring 6. A positioning bracket 9 is fixedly installed on the top of the rotating joint 5, and a lifting bracket 10 is rotatably installed on the positioning bracket 9. Lifting rods 11 are fixedly installed on both sides of the lifting bracket 10. A lifting fixing knot 12 is fixedly sleeved on the placement fixing frame 4, and a lifting hydraulic rod 13 is rotatably installed on one side of the lifting fixing knot 12. The telescopic end of the lifting hydraulic rod 13 is obliquely upward and rotatably installed at the bottom of one of the lifting rods 11, as shown in FIG. Figure 4As shown, the ends of the two lifting rods 11 that are away from each other are fixedly installed with a hanging rod 14, and the axis position of the hanging rod 14 is on the same vertical plane as the position of the three-finger pneumatic mechanism 2; specifically, when the quick clamp for processing automobile parts is in use, a sorting component is set, so that when the annular parts are clamped and transported, the lifting hydraulic rod 13 is first controlled to extend, driving one of the lifting rods 11 to lift upward, so that the hanging rod 14, the lifting rod 11 and the lifting bracket 10 are rotated along the positioning bracket 9 for a certain angle as a whole, so that one of the hanging rods 14 is lifted upward, and then a plurality of annular parts to be processed are hung on the hanging rod 14 in batches, the lifting hydraulic rod 13 is reset, and the two lifting hydraulic rods 13 are restored to a horizontal state, and then the driving motor 7 drives the steering gear ring 6 to rotate through the driving gear 8, thereby driving the lifting rod 11 and the hanging rod 14 along the positioning bracket 9. The fixed frame 4 is rotated to make the hanging rod 14 on which the annular accessory is hung rotate to one side of the transfer robot arm 1, and the transfer robot arm 1 drives the three-finger pneumatic mechanism 2 to approach the hanging rod 14, and controls the three arc-shaped clamping claws 3 to approach and clamp the annular accessory at the farthest end, and the transfer robot arm 1 carries the annular accessory to the subsequent processing station. When the annular accessory on the hanging rod 14 is transported, the lifting hydraulic rod 13 begins to contract, driving the hanging rod 14 on the other side to lift up, and then repeat the above operation, by hanging the annular accessory on the upper hanging rod 14, the annular accessory is kept in a suspended and drooping state and is quickly clamped by the three-finger pneumatic mechanism 2 and the arc-shaped clamping claw 3, and the annular accessory with an eccentric point will automatically rotate downward due to its own gravity, so that the annular accessory with an irregular structure will also maintain the same posture and orientation, which is convenient for the three-finger pneumatic mechanism 2 to quickly clamp.

[0020] like Figure 5 , Figure 7 As shown, a linear guide 15 is fixedly installed on the top of the lifting rod 11, and an electric slider 16 is driven to be installed on the top of the linear guide 15. A push frame 17 is fixedly installed on the top of the electric slider 16, and a push ring 18 is fixedly installed on the ends of the two push frames 17 that are away from each other, and the two push rings 18 are respectively movably sleeved on the two hanging rods 14; specifically, by setting the push ring 18, during the process of the transfer robot arm 1 and the three-finger pneumatic mechanism 2 clamping and transferring the annular accessories on the hanging rod 14, if the accessory at the farthest end is clamped, the electric slider 16 on the lifting rod 11 on the same side will drive the push frame 17 to move along the linear guide 15 toward one end of the hanging rod 14, so that the push ring 18 approaches the accessory queue along the hanging rod 14, and pushes the accessory queue to slide on the hanging rod 14, so that the empty space of the accessory is filled, so that the three-finger pneumatic mechanism 2 can clamp the accessory again at the same position when it is reset, thereby greatly shortening the time for positioning the fixture, so that the transfer robot arm 1 and the three-finger pneumatic mechanism 2 can quickly transfer the accessory.

[0021] like Figure 6As shown, rubber sleeves 19 are sleeved on the suspension rods 14, and the two rubber sleeves 19 are respectively located inside the two push rings 18; specifically, by setting the rubber sleeves 19, the rubber sleeves 19 are sleeved on the suspension rods 14. The rubber sleeves 19 can prevent the annular fittings from directly contacting the suspension rods 14, and prevent relative sliding between the inner ring of the fitting and the suspension rod 14 when the push ring 18 pushes the fitting, resulting in wear of both. At the same time, the rubber sleeves 19 can increase the frictional resistance when the fitting moves on the suspension rod 14, effectively preventing the fitting from falling directly from one end of the suspension rod 14 due to excessive sliding caused by inertia when being pushed by the push ring 18.

[0022] As Figure 4 shown, a suspension frame 20 is fixedly installed at the top of the lifting bracket 10. As Figure 7 shown, a vertically arranged clamping electric push rod 21 is fixedly installed inside the suspension frame 20. The telescopic end of the clamping electric push rod 21 faces downward and is fixedly installed with a horizontally arranged pressing plate 22. Two arc-shaped pressing rods 23 are fixedly installed at both ends of the pressing plate 22. The four arc-shaped pressing rods 23 are symmetrically distributed at the tops of the two suspension rods 14 respectively. In this embodiment, the three arc-shaped clamping jaws 3 are in a "pin" - shaped distribution formation and are staggered with the two arc-shaped pressing rods 23; specifically, by setting the arc-shaped pressing rods 23, after the annular fitting is completely suspended on one of the suspension rods 14, the clamping electric push rod 21 at the top of the lifting bracket 10 will drive the pressing plate 22 to descend, and then drive the arc-shaped pressing rods 23 on both sides to move downward and press on both sides of the top of the annular fitting, so that the two arc-shaped pressing rods 23 cooperate with the middle suspension rod 14 to form a three-point clamping of the fitting, so that the fitting is stably clamped on the suspension rod 14 and will not be thrown off from one end of the suspension rod 14 due to the centrifugal force generated by the rotation of the rotating joint 5. When the three-finger pneumatic mechanism 2 clamps the fitting, the clamping electric push rod 21 drives the arc-shaped pressing rods 23 to reset and releases the restriction on the fitting.

[0023] As Figure 7 shown, balance rods 24 parallel to the pressing plate 22 are arranged on both sides of the pressing plate 22. The two ends of the balance rods 24 are respectively fixedly installed on the two arc-shaped pressing rods 23; specifically, by setting the balance rods 24, the balance rods 24 on both sides of the pressing plate 22 can be respectively fixed to one end of a total of four arc-shaped pressing rods 23 on both sides, thereby applying a certain pulling force to the arc-shaped pressing rods 23, dispersing the loads at both ends of the pressing plate 22, thereby reducing the bending moment at the connection between the arc-shaped pressing rods 23 and the pressing plate 22, and preventing one end of the arc-shaped pressing rods 23 from sinking after long-term use, affecting the clamping and restricting effect of the arc-shaped pressing rods 23 on the fitting.

[0024] As Figure 1 shown, a feeding rack 25 is arranged on the side of the placing and fixing rack 4背离转运机械臂1的一侧设置有放料架25,如 Figure 8 It should be noted that there is an unclear part in the original text where "背离转运机械臂1的一侧" is not accurately translated as there is an unknown Chinese character "背离". It is translated as "the side away from the transfer robotic arm 1" for now, assuming this is the correct meaning. You may need to check and correct it according to the actual situation.As shown, a discharge pipe 26 is fixedly installed at the top of the discharge rack 25. In this embodiment, the inner diameter of the discharge pipe 26 is close to the outer diameter of the annular accessory to be transported. The discharge pipe 26 and the discharge rack 25 are detachably connected by screw connection or the like, so that the discharge pipe 26 can be replaced. The discharge pipe 26 is tilted, and one end of the discharge pipe 26 is obliquely arranged and fixedly installed with a flared pipe 27, and the other end of the discharge pipe 26 faces the placement fixing frame 4 and is provided with a plurality of make way grooves 2601, which are adapted to the lifting hydraulic rod 13 and the arc pressure rod 23. Specifically, by setting the discharge pipe 26, when one of the hanging rods 14 is lifted upward, the hanging rod 14 and its top The arc-shaped pressure rods 23 on both sides of the part will pass through the give way groove 2601 and move to the inside of the discharge pipe 26, so that the discharge pipe 26 is consistent with the axis of the hanging rod 14. At this time, the staff can directly put the annular accessories into the discharge pipe 26 through the flared tube 27. Since the hanging rod 14 is at the center of the axis of the discharge pipe 26, the annular accessories will automatically fall directly to the bottom of the discharge pipe 26 and hang on the hanging rod 14, and slide down along the inclined hanging rod 14, which greatly facilitates the loading operation of the accessories and greatly simplifies the loading operation of the staff. At the same time, the discharge pipe 26 and the flared tube 27 enable the staff to maintain a sufficient safety distance from the sorting components, the transfer robot arm 1, and the processing station to reduce the operation risk.

[0025] like Figure 3 As shown, an assembly frame 28 is fixedly installed on the top of the three-finger pneumatic mechanism 2, and a photoelectric sensor 29 is fixedly installed on the bottom of the assembly frame 28, and the position of the photoelectric sensor 29 corresponds to the position of the suspension rod 14; specifically, by setting the photoelectric sensor 29, when the transfer robot arm 1 drives the three-finger pneumatic mechanism 2 to approach the annular accessory on one end of the suspension rod 14, the photoelectric sensor 29 that moves with the three-finger pneumatic mechanism 2 will sense the position of the accessory in advance, and then monitor and correct the moving trajectory and moving stroke of the three-finger pneumatic mechanism 2 in real time, to ensure that the three arc-shaped jaws 3 can accurately stay on the surrounding side of the annular accessory, to ensure that the three-finger pneumatic mechanism 2 moves into place and does not move excessively, to further reduce the positioning time and improve the positioning accuracy.

[0026] like Figure 3 As shown, blocking plates 30 are fixedly installed on both sides of both ends of the arc-shaped clamping jaws 3; specifically, by setting the blocking plates 30, when the three-finger pneumatic mechanism 2 drives the three arc-shaped clamping jaws 3 to clamp on the outer ring of the annular accessory, the blocking plates 30 on the front and rear sides of both ends of the arc-shaped clamping jaws 3 will be respectively stuck on the front end surface and the rear end surface of the annular accessory, so that the annular accessory is clamped by the arc-shaped clamping jaws 3 while being surrounded by the array of blocking plates 30, effectively preventing the annular accessory and the arc-shaped clamping jaws 3 from relative slipping during the process of transporting the accessory by the transfer robot arm 1, thereby preventing the positioning or clamping failure.

[0027] In summary, when the quick clamp for processing automobile parts is used, a sorting component is set so that when the annular parts are clamped and transported, the lifting hydraulic rod 13 is first controlled to extend, driving one of the lifting rods 11 to lift upward, so that the hanging rod 14, the lifting rod 11 and the lifting bracket 10 are rotated along the positioning bracket 9 by a certain angle as a whole, so that one of the hanging rods 14 is lifted upward, and then a plurality of annular parts to be processed are hung on the hanging rod 14 in batches, the lifting hydraulic rod 13 is reset, and the two lifting hydraulic rods 13 are restored to a horizontal state, and then the driving motor 7 drives the steering gear ring 6 to rotate through the driving gear 8, and then drives the lifting rod 11 and the hanging rod 14 to rotate along the placement fixing frame 4, so that the hanging rod 14 with the annular parts hung thereon is transferred to the transporting machine. On one side of the arm 1, the transfer robot arm 1 drives the three-finger pneumatic mechanism 2 to approach the hanging rod 14, and controls the three arc-shaped clamping claws 3 to approach and clamp the farthest annular accessory. The transfer robot arm 1 carries the annular accessory to the subsequent processing station. When the annular accessory on the hanging rod 14 is transported, the lifting hydraulic rod 13 begins to contract, driving the hanging rod 14 on the other side to lift up, and then repeats the above operation. By hanging the annular accessory on the upper hanging rod 14, the annular accessory is kept in a suspended and drooping state and is quickly clamped by the three-finger pneumatic mechanism 2 and the arc-shaped clamping claw 3. The annular accessory with an eccentric weight will automatically rotate downward under the action of its own gravity, so that the annular accessory with an irregular structure will also maintain the same posture and orientation, which is convenient for the three-finger pneumatic mechanism 2 Quick clamping, by setting the push ring 18, during the process of the transfer robot arm 1 and the three-finger pneumatic mechanism 2 clamping and transferring the annular accessories on the hanging rod 14, if the accessories at the farthest end are clamped, the electric slider 16 on the lifting rod 11 on the same side will drive the push frame 17 to move along the linear guide rail 15 toward one end of the hanging rod 14, so that the push ring 18 approaches the accessories queue along the hanging rod 14 and pushes the accessories queue to slide on the hanging rod 14, so that the empty space of the accessories is replenished, so that the three-finger pneumatic mechanism 2 can clamp the accessories again at the same position when it is reset, thereby greatly shortening the positioning time of the clamp, so that the transfer robot arm 1 and the three-finger pneumatic mechanism 2 can quickly transfer the accessories, and by setting the rubber sleeve 19, the rubber sleeve 19 is sleeved on the hanging rod 14, and the rubber The sleeve 19 can avoid direct contact between the annular accessory and the suspension rod 14, and prevent relative sliding between the inner ring of the accessory and the suspension rod 14 when the push ring 18 pushes the accessory, resulting in wear between the two. At the same time, the rubber sleeve 19 can increase the friction resistance of the accessory when it moves on the suspension rod 14, and effectively prevent the accessory from falling directly from one end of the suspension rod 14 due to excessive slipping due to inertia when the push ring 18 pushes. By setting the arc pressure rod 23, after all the annular accessories are hung on one of the suspension rods 14, the clamping electric push rod 21 on the top of the lifting bracket 10 will drive the pressure plate 22 to descend, thereby driving the arc pressure rods 23 on both sides to move down and press on the top two sides of the annular accessory, so that the two arc pressure rods 23 cooperate with the middle suspension rod 14 to form a three-point clamp for the accessory.The accessory is stably clamped on the suspension rod 14 and will not be thrown off from one end of the suspension rod 14 due to the centrifugal force generated by the rotation of the rotating joint 5. When the three-finger pneumatic mechanism 2 clamps the accessory, the clamping electric push rod 21 drives the arc pressure rod 23 to reset, releasing the restriction on the accessory. By setting the balance rod 24, the balance rods 24 on both sides of the pressure plate 22 can be respectively fixed to one end of a total of four arc pressure rods 23 on both sides, thereby applying a certain pulling force to the arc pressure rod 23, dispersing the loads at both ends of the pressure plate 22, thereby reducing the bending moment at the connection between the arc pressure rod 23 and the pressure plate 22, and preventing the arc pressure rod 23 from being bent after long-term use. The tendency of one end to sink affects the clamping and limiting effect of the arc pressure rod 23 on the accessories. By setting the discharge pipe 26, when one of the hanging rods 14 is lifted upward, the hanging rod 14 and the arc pressure rods 23 on both sides of its top will pass through the give way groove 2601 and move to the inside of the discharge pipe 26, so that the discharge pipe 26 is consistent with the axis of the hanging rod 14. At this time, the staff can directly put the annular accessory into the discharge pipe 26 through the flared pipe 27. Since the hanging rod 14 is at the center of the axis of the discharge pipe 26, the annular accessory will automatically fall directly to the bottom of the discharge pipe 26 and hang on the hanging rod 14, and move along the inclined hanging rod 1 4 slides down, which greatly facilitates the loading operation of the accessories and greatly simplifies the loading operation of the staff. At the same time, the discharge pipe 26 and the expansion pipe 27 allow the staff to maintain a sufficient safe distance from the sorting components, the transfer robot arm 1, and the processing station to reduce the operation risk. By setting the photoelectric sensor 29, when the transfer robot arm 1 drives the three-finger pneumatic mechanism 2 to approach the annular accessory on one end of the suspension rod 14, the photoelectric sensor 29 moving with the three-finger pneumatic mechanism 2 will sense the position of the accessory in advance, and then monitor and correct the moving trajectory and moving stroke of the three-finger pneumatic mechanism 2 in real time to ensure that the three arc-shaped clamps 3 can In order to accurately stay on the circumference of the annular accessory, ensure that the three-finger pneumatic mechanism 2 moves into place and does not move excessively, further reduce positioning time, and improve positioning accuracy. By setting the blocking plate 30, when the three-finger pneumatic mechanism 2 drives the three arc-shaped clamps 3 to clamp on the outer ring of the annular accessory, the blocking plates 30 on both sides of the arc-shaped clamps 3 will be respectively stuck on the front and rear surfaces of the annular accessory, so that the annular accessory is clamped by the arc-shaped clamps 3 while being surrounded by the blocking plate 30 array, effectively preventing the annular accessory and the arc-shaped clamps 3 from relative slipping during the process of the transfer robot arm 1 transferring the accessory, resulting in positioning or clamping failure.
