Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to multi-channel bearing needle installation equipment. Background Art

[0002] Plane bearings (thrust bearings) are components composed of a plane cage assembly with needle rollers or cylindrical rollers or steel balls and a plane washer. Plane bearings are divided into plane bearings with needle rollers and plane bearings with balls.

[0003] The plane needle roller and the bearing housing (cage assembly) are the main components of the plane needle roller bearing. During the processing of the plane needle roller bearing, installing the needle into the bearing housing is a crucial process. Although there is an automatic needle loading machine to realize the one-time rapid and automatic installation of multiple needle rollers, during the processing and forming of the needle roller groove, the inner and outer rings of the bearing housing may be deformed due to clamping pressure, cutting force, processing heat deformation, tool wear, etc., resulting in the failure of the needle loading work.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present application can control the baffle to flip open during the process of pushing the bearing shell into the second bearing channel when the inner and outer rings of the bearing shell are unqualified, the needle roller groove on the bearing shell is unqualified, foreign matter exists inside the needle roller groove, etc., resulting in a failure in needle installation. The bearing shell falls into a pre-placed box by only setting a first bearing channel for transporting the bearing shell, a second bearing channel for quality inspection and needle installation of the bearing shell, and a third bearing channel for transporting the bearing shell after needle installation. This can meet the diversion of bearing shells with unqualified processing quality and bearing shells after needle installation, and automatically adjust the processing steps according to the quality of the bearing shell, reduce the occurrence of invalid processing, and reduce waste of resources.

[0017] 2. In the present application, after the hollow frame rotates under the action of the needle roller and contacts the sensor fixedly installed on the second curved block, the human-computer interaction device that receives the sensor feedback counts once, and then after the hollow frame leaves the needle roller movement path, the needle roller moves away from the hollow frame. Because a torsion spring is installed between the side of the hollow frame away from the sensor and the second curved block, the torsion spring contracts and the hollow frame moves back to the next needle roller movement path. When the needle roller groove fails to be installed due to unqualified needle roller groove forming, foreign matter inside the needle roller groove, etc., the sensor is not hit enough times by the hollow frame during one rotation of the bearing housing, and the human-computer interaction device controls the second bearing material channel and the third bearing material channel to cooperate to complete the bearing housing diversion work.

[0018] 3. In the present application, the curved surface block 1 can play the role of blocking and limiting the bearing shell, so as to prevent the bearing shell from continuing to move due to inertia after entering the processing position even if the multi-stage telescopic pneumatic cylinder 1 stops working, causing the needle loading machine and the bearing shell to be misaligned, thereby ensuring the accurate position control of the bearing shell.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example: Figure 1-Figure 14As shown, the present invention provides a technical solution for a multi-channel bearing needle loading device, including a first bearing channel 1, a bearing housing 2, a needle loading machine 3 and a box 6. A second bearing channel 4 is arranged on one side of the first bearing channel 1, and a third bearing channel 5 is arranged on one side of the second bearing channel 4. The second bearing channel 4 includes a supporting base plate 41 and a multi-stage telescopic pneumatic cylinder 413 fixedly installed at the bottom of the supporting base plate 41. A circular cavity 435 and a reserved cavity 436 are opened at the top of the supporting base plate 41. A circular bracket 421 is arranged inside the circular cavity 435, and a friction clamping component is installed on the circular bracket 421. A gear 420 is installed at the bottom of the friction clamping assembly, and a gear 2 427 is meshed with one side of the gear 420. A damper 419 is rotatably connected to the bottom of the gear 420. A hydraulic control assembly is installed on the outside of the gear 420. A curved block 416 is arranged at the bottom of the reserved cavity 436, and a transmission cross plate 417 is fixedly connected to one side of the curved block 416. The transmission cross plate 417 cooperates with the hydraulic control assembly to control the working state of the friction clamping assembly. An installation box 437 is fixedly installed on one side of the curved block 416, and a displacement sensor 7 and a needle detection assembly are arranged inside the installation box 437.

[0036] Specifically, when the multi-channel needle loading equipment consisting of the first bearing channel 1, the needle loading machine 3, the second bearing channel 4 and the third bearing channel 5 is used, a human-machine interaction device control device is set on the multi-channel needle loading equipment to perform automated work. This is an existing public technology and will not be described in detail here.

[0037] Specifically, the equipment mounting frame 11 in the first bearing material channel 1 is used to install the conveying device 12, and the conveying device 12 is used to convey the bearing housing 2. Two guide bent plates 13 are fixedly installed on the top of the equipment mounting frame 11. The two guide bent plates 13 symmetrically arranged on both sides of the top of the equipment mounting frame 11 constitute a limiting channel for the movement of the bearing housing 2, and the bearing housing 2 is limited to prevent it from deviating from the preset movement trajectory; a receiving groove 16 is opened on one side of the guide bent plate 13 away from the second bearing material channel 4, and the receiving groove The side of the pusher rack 15 inserted on the one-16 facing the bearing housing 2 is a concave curved surface, and a multi-stage telescopic pneumatic cylinder 14 is fixedly installed on the side of the pusher rack 15 away from the second bearing material channel 4. The fixed frame 3 18 fixedly installed outside the multi-stage telescopic pneumatic cylinder 14 is fixedly installed together with the guide curved plate 13, and a material conveying channel 17 is opened on the guide curved plate 13 close to the second bearing material channel 4. The bearing housing 2 transported by the conveying device 12 can move between the pusher rack 15 and the material conveying channel 17. Figure 2 shown.

[0038] When a bearing housing 2 is transported by the conveying device 12 to between the push rack 15 and the material passage 17, the multi-stage telescopic pneumatic cylinder 14 is controlled to work, and the multi-stage telescopic pneumatic cylinder 14 pushes the fixed push rack 15 to move, and the push rack 15 pushes the bearing housing 2 to move to the supporting bottom plate 41 set at the bottom of one side of the material passage 17, so that the bearing housing 2 moves from the first bearing material passage 1 to the second bearing material passage 4. While controlling the multi-stage telescopic pneumatic cylinder 14 to work, the control The multi-stage telescopic pneumatic cylinder 3 413 fixedly installed at the bottom of the support base plate 41 works for the first time. The multi-stage telescopic pneumatic cylinder 3 413 works and contracts to drive the curved surface block 1 416 to move upward. The upward curved surface block 1 416 partially penetrates the reserved cavity 436 opened at the top of the support base plate 41 and moves to the top of the support base plate 41. Part of the curved surface block 1 416 moves to the path where the bearing housing 2 is pushed and displaced by the multi-stage telescopic pneumatic cylinder 14. The multi-stage telescopic pneumatic cylinder 3 413 finishes working for the first time and stops working.

[0039] Since the multi-stage telescopic pneumatic cylinder 14 pushes the bearing housing 2 to move toward the curved surface block 416 through the pushing frame 15 along a long movement path, the bearing housing 2 will move into the concave surface of the curved surface block 416 and be blocked and limited by the curved surface block 416 only after the multi-stage telescopic pneumatic cylinder 413 has finished working for the first time. At this time, the bearing housing 2 enters the bottom of the needle loading machine 3 and enters the processing position. The curved surface block 416 blocks and limits the bearing housing 2 at this time, avoiding the bearing housing 2 from continuing to move due to inertia after entering the processing position even if the multi-stage telescopic pneumatic cylinder 14 stops working, resulting in the misalignment of the needle loading machine 3 and the bearing housing 2, thereby ensuring the accurate position control of the bearing housing 2.

[0040] After the movement, the transmission cross plate 417 fixedly installed on one side of the curved block 416 moves to the bottom of the rotating ring 3 425 in the hydraulic control assembly, and at this time, the bearing housing 2 is arranged between the concave surface of the pusher rack 15 and the concave surface of the curved block 416. Under the support and limit of the pusher rack 15 and the curved block 416, the bearing housing 2 can only move horizontally up and down.

[0041] After the multi-stage telescopic pneumatic cylinder 14 stops working, the multi-stage telescopic pneumatic cylinder 3 413 is controlled to work for the second time. The multi-stage telescopic pneumatic cylinder 3 413 continues to work to retract the curved surface block 1 416 to move upward, and the installation box 437 fixedly installed with the curved surface block 1 416 moves upward, so that the curved surface block 2 442 installed inside the installation box 437 moves to the top of the supporting bottom plate 41, and the curved surface block 2 442 enters the detection station. In this process, the curved surface block 1 416 drives the fixedly connected transmission cross plate 417 to move upward. Since the rotating ring 1 422 in the hydraulic control component is rotatably installed at the bottom of the circular bracket 421, a plurality of damper 2 423 are fixedly installed between the rotating ring 1 422 and the rotating ring 2 424, and the damper 2 423 can move forward only after being subjected to a certain force. The circular bracket 421 is forced to move upward, and the circular bracket 421 with a constant outer diameter is inserted into the bearing housing 2. As the curved block 416 moves upward, the circular bracket 421 moves to the top of the supporting bottom plate 41. The bottom of the liquid storage tank 428 fixedly installed inside the circular bracket 421 is fixedly connected to the gear 1 420. The damper 1 419 fixedly connected to the bottom of the gear 1 420 is extended to the limit. Therefore, at this time The support base plate 41 limits the gear 1 420 by means of the damper 1 419 fixedly installed by the fixing frame 1 418, the gear 1 420 is restricted from moving upward, the liquid storage tank 428 fixed to the gear 1 420 and the circular bracket 421 fixed outside the liquid storage tank 428 are limited from moving upward, and the damper 2 423 is limited from moving upward as a whole. Therefore, at this time, the force applied by the transmission cross plate 417 which continues to move upward to the rotating ring 3 425 acts on the damper 2 423 through the rotating ring 2 424, the damper 2 423 contracts, and the rotating ring 3 425 moves toward the elastic liquid storage part 430 in the hydraulic control assembly. After the rotating ring 3 425 applies a certain extrusion force to the elastic liquid storage part 430, the hollow guide frame 429 fixedly connected to the elastic liquid storage part 430 and the friction clamp The liquid storage tank 428 in the component is fixedly connected, so the liquid medium inside the elastic liquid storage member 430 enters the liquid storage tank 428 through the hollow guide frame 429, the internal hydraulic pressure of the liquid storage tank 428 rises, and the internal hydraulic pressure of multiple hydraulic telescopic rods 431 fixedly connected to the liquid storage tank 428 rises, and the friction block 432 fixedly connected to the piston end of the hydraulic telescopic rod 431 extends and moves, and the curved surface on one side of the friction block 432 is tightly attached to the inner wall of the bearing shell 2, and finally the multiple friction blocks 432 support and fix the bearing shell 2. At this time, the bearing shell 2 moves synchronously with the liquid storage tank 428 and the circular bracket 421. At this time, the second work of the multi-stage telescopic pneumatic cylinder three 413 is completed, the curved surface block one 416 stops moving up, the transmission cross plate 417 stops moving up, and the rotating ring three 425 stops moving up.The curved surface block 2 442 enters the inspection station to complete the clamping work of the bearing housing 2.

[0042] After the second operation of the multi-stage telescopic pneumatic cylinder 3 413 is completed, the electric push rod 1 441 in the second bearing material channel 4 is controlled to work. When the electric push rod 1 441 fixedly installed on the partition plate 439 fixedly installed inside the installation box 437 is retracted, the guide frame 2 438 inserted on the partition plate 439 will lose its support limit. Since the piston end of the electric push rod 1 441 is only in contact with the guide frame 2 438, and the guide frame 2 438 is fixedly installed with a curved surface block 2 442, there are two supporting springs 440 fixedly connected between the partition plate 439 that cannot move and the curved surface block 2 442. At this time, the guide frame 2 438 and the curved surface block 2 442 are pushed to move by the rebounding supporting spring 440, and the storage groove 3 446 opened on the curved surface block 1 416 provides a channel for the curved surface block 2 442 to move toward the outside of the bearing housing 2. The displacement sensor 7 fixedly installed on the partition plate 439 works to detect the movement distance of the rotating ring 1 422, and the preparation work for the needle installation detection of the bearing housing 2 is completed;

[0043] Subsequently, the motor 426 fixedly connected to the top of the transmission horizontal plate 417 is controlled to work for the first time, and the working motor 426 drives the second gear 427 fixedly installed on the outer side of the output end to rotate, and the rotating second gear 427 drives the meshing gear 1 420 to rotate, and the gear 1 420 drives the fixed liquid storage tank 428 and the circular bracket 421 fixed on the outer side of the liquid storage tank 428 to rotate, and after the circular bracket 421 drives the bearing housing 2 to rotate for one circle, the motor 426 stops working, and the preparation work for the needle installation of the bearing housing 2 is completed;

[0044] Subsequently, the multi-stage telescopic pneumatic cylinder 14 is controlled to work and reset, and the pusher rack 15 is reset;

[0045] Subsequently, the motor 426 is controlled to work for the second time, and the motor 426 drives the bearing housing 2 to rotate through the gear 2 427, the gear 1 420, the circular bracket 421 and other structures. Under the cooperation of the sensor structure of the needle loading machine 3, when a certain needle roller groove on the bearing housing 2 moves and aligns with the needle output structure of the needle loading machine 3, the motor 426 stops working, and the preparation work of the needle loading of the bearing housing 2 is completed;

[0046] Subsequently, the motor 426 is controlled to work for the third time. During this working process, the motor 426 briefly pauses for several times according to the number of needle roller grooves on the bearing housing 2. The bearing housing 2 rotates and pauses for several times. The needle loading machine 3 loads needles into the needle roller grooves on the bearing housing 2 during the pause time of the bearing housing 2. After the needle loading is completed, the bearing housing 2 stops working, and the needle loading work of the bearing housing 2 is completed.

[0047] Then, the motor 426 is controlled to work for the fourth time, and the motor 426 drives the bearing housing 2 to rotate one circle through the gear 2 427, the gear 1 420, the circular bracket 421 and other structures, thereby completing the needle installation detection work of the bearing housing 2;

[0048] Subsequently, the electric push rod 441 in the second bearing material channel 4 is controlled to work and extend, and the electric push rod 441 pushes the guide frame 438, so that the guide frame 438 drives the curved block 442 to enter the storage groove 3 446 opened on the curved block 416, and then the multi-stage telescopic pneumatic cylinder 3 413 is controlled to work and extend to push the curved block 416 to reset, and the transmission cross plate 417 moves down and resets, the damper 2 423 loses the pressure and rebounds to extend, the elastic liquid storage part 430 loses the pressure and expands to absorb liquid from the liquid storage tank 428, the internal hydraulic pressure of the liquid storage tank 428 and the hydraulic telescopic rod 431 is restored, the friction block 432 is reset and no longer contacts the inner wall of the bearing housing 2, and under the action of the contracted damper 419, the circular bracket 421 moves down and resets, the bearing housing 2 loses its fixation, and the release of the bearing housing 2 is completed.

[0049] Subsequently, a multi-stage telescopic pneumatic cylinder 49 fixedly supported by a U-shaped frame 48 fixedly installed on a U-shaped frame 42 is controlled to work, and the multi-stage telescopic pneumatic cylinder 49 pushes a pusher rack 410 fixedly installed on the piston end to move toward a feeding channel 412 opened on another U-shaped frame 42, and the moving pusher rack 410 pushes the needle-installed bearing housing 2 to move through the feeding channel 412 to the inside of the feeding pipe 54 in the third bearing material channel 5, and finally the needle-installed bearing housing 2 moves to the conveying device 52 installed inside the equipment mounting frame 51, and is transported by the conveying device 52 to the next processing station, completing the transportation of the bearing housing 2.

[0050] During the needle installation process of the above-mentioned bearing shell 2, if the inner ring of the bearing shell 2 is deformed due to the forming of the needle roller groove on the bearing shell 2, clamping pressure, cutting force, processing thermal deformation, tool wear and other reasons, when the bearing shell 2 is clamped, since the pusher frame 15 and the curved block 1 416 support the lower bearing shell 2 to only be able to move horizontally up and down, the upward circular bracket 421 cannot enter the interior of the bearing shell 2 but instead lifts up the bearing shell 2. Therefore, when the subsequent preparation work for the needle installation detection of the bearing shell 2 is carried out, the upwardly moved bearing shell 2 is not on the movement path of the curved block 2 442, and the movement of the curved block 2 442 will not be blocked by the bearing shell 2. The distance data detected by the displacement sensor 7 for detecting the movement distance of the curved block 2 442 is fed back to the human-machine interaction device in real time. At this time, the human-machine interaction device directly controls the second bearing material channel 4 to release the bearing shell 2.

[0051] Then, the multi-stage telescopic pneumatic cylinder 14 is controlled to work and drive the push rack 15 to reset, and then the electric push rod 2 57 in the third bearing material channel 5 works to retract, and the electric push rod 2 57 drives the top plate 58 fixed at the piston end to move away from the bottom of the baffle plate 55, and the baffle plate 55 is rotatably installed on the fixed rack 2 56 fixedly installed at the bottom of the feeding pipe 54. Under the action of gravity, the baffle plate 55 rotates and falls, so that the bottom channel of the feeding pipe 54 is released, and then the second bearing material channel 4 is controlled to transport the bearing shell 2. When the bearing shell 2 moves into the feeding pipe 54, the bearing shell 2 will fall into the box 6 set at the bottom of the feeding pipe 54, completing the diversion of the bearing shell 2. In the process of installing the needle on the bearing shell 2, whether the inner ring of the bearing shell 2 is deformed is detected and the working steps of the multi-channel needle installation equipment are controlled according to the detection results, thereby reducing invalid processing and reducing invalid costs;

[0052] If the inner ring of the bearing shell 2 is normal, the circular bracket 421 enters the interior of the bearing shell 2 normally during the clamping work of the bearing shell 2. However, the outer ring of the bearing shell 2 is deformed due to processing. During the preparation work for the needle installation of the bearing shell 2, the curved block 442 supported by the support spring 440 is attached to the outer side of the bearing shell 2. During the rotation of the bearing shell 2, the support spring 440 applies a thrust to the curved block 442 in real time. Therefore, the curved block 442 will move with the change of the outer ring of the bearing shell 2. The distance data detected by the displacement sensor 7 for detecting the movement distance of the curved block 442 is fed back to the human-machine interaction device in real time. After the preparation work for the needle installation of the bearing shell 2 is completed, the human-machine interaction device determines that the deformation of the outer ring of the bearing shell 2 exceeds the preset degree according to the detection result of the displacement sensor 7. The human-machine interaction device directly controls the second bearing channel 4 to release the bearing shell 2, and controls the second bearing channel 4 and the third bearing channel 5 to cooperate to complete the diversion work of the bearing shell 2.

[0053] Through the cooperation of the second bearing material channel 4 and the third bearing material channel 5, the inner and outer rings of the bearing shell 2 are inspected during the clamping and positioning process before the needle is installed in the bearing shell 2, so as to avoid the situation that the bearing shell 2 is still scrapped due to quality problems after the needle is installed, reduce the waste of roller needles, reduce the waste of resources caused by ineffective processing, reduce the failure of the needle installation machine 3, and reduce the damage to the needle installation machine 3.

[0054] When the needle installation work of the bearing shell 2 is completed, since the hollow frame 443 in the needle installation detection assembly is symmetrically arranged with the needle outlet structure of the needle installation machine 3, the curved surface block 442 is not affected by the needle roller. At this time, the hollow frame 443 is located at the top of the bearing shell 2 and is in a state of perpendicular intersection with the curved surface block 442; therefore, during the needle installation detection work of the bearing shell 2, the bearing shell 2 that rotates one circle will drive the needle rollers in multiple needle roller grooves to contact the hollow frame 443 one by one. Because the hollow frame 443 is partially arranged inside the groove formed on the curved surface block 442 and is rotatably connected to the curved surface block 442, the hollow frame 443 rotates under the action of the needle roller and contacts the sensor 445 fixedly installed on the curved surface block 442. After the touch, the human-machine interaction device receiving the feedback from the sensor 445 counts once, and then after the hollow frame 443 leaves the needle roller movement path, the needle roller moves away from the hollow frame 443, because a torsion spring 444 is installed between the side of the hollow frame 443 away from the sensor 445 and the curved surface block 2 442, at this time, the torsion spring 444 contracts and causes the hollow frame 443 to move and reset to stay on the next needle roller movement path. When the needle roller groove fails to be installed due to unqualified needle roller groove molding, foreign matter in the needle roller groove, etc., the sensor 445 is not hit enough times by the hollow frame 443 during the rotation of the bearing housing 2, and the human-machine interaction device controls the second bearing material channel 4 and the third bearing material channel 5 to cooperate to complete the diversion work of the bearing housing 2;

[0055] During use, the multi-channel needle loading equipment composed of the second bearing channel 4 and the third bearing channel 5 provided in the present application can control the baffle plate 55 to flip open during the process of pushing the bearing shell 2 out of the second bearing channel 4 when the inner and outer rings of the bearing shell 2 are unqualified, the needle roller groove on the bearing shell 2 is unqualified, there are foreign objects inside the needle roller groove, etc., so that the bearing shell 2 falls into the pre-placed box 6. It is only necessary to set the first bearing channel 1 for transporting the bearing shell 2, the second bearing channel 4 for quality inspection and needle loading of the bearing shell 2, and the third bearing channel 5 for transporting the bearing shell 2 after needle loading, so as to meet the diversion of the bearing shell 2 with unqualified processing quality and the bearing shell 2 after needle loading, and automatically adjust the processing steps according to the quality of the bearing shell 2, reduce the occurrence of invalid processing, and reduce waste of resources.

[0056] In addition, such as Figure 6 As shown, the rotating ring three 425 is sleeved on the outside of the gear one 420, and the up and down movement of the rotating ring three 425 will not affect the rotation of the gear one 420. The motor 426 penetrates the rotating ring three 425 and contacts the rotating ring three 425, and the motor 426 and the rotating ring three 425 can move relative to each other.

[0057] In addition, such as Figure 1 , Figure 4 and Fig.12As shown, the needle loading machine 3 is installed on the top of the second bearing material channel 4, and a long groove 43 is provided on the U-shaped frame 42 fixedly installed on the top of the support base plate 41. The long groove 43 provides a channel for the needle loading machine 3 to perform needle loading work, and a waste discharge groove 44 is provided on the side of the support base plate 41 away from the first bearing material channel 1. A collecting hopper 45 is arranged at the bottom of the waste discharge groove 44 and is fixedly installed together with the support base plate 41. When it is found that the needle roller at the top of the bearing housing 2 is missing during the detection of the needle loading detection component, since the number of needle rollers output by the needle loading machine 3 each time is set according to the setting of the needle roller groove on the bearing housing 2, the multi-stage telescopic pneumatic cylinder 14 can be controlled to push the pushing frame 15 to reciprocate on the top of the support base plate 41, and the needle roller at the top of the support base plate 41 is pushed, so that the needle roller falls into the collecting hopper 45 through the waste discharge groove 44, and the guide tube 46 fixedly connected to the bottom of the collecting hopper 45 is partially arranged inside the box 6, so the needle roller is guided by the collecting hopper 45 and the guide tube 46 into the box 6 for storage;

[0058] Furthermore, the guide tube 46 is made of rubber material and can be deformed to a certain extent, so the movement of the box 6 will not be affected by the guide tube 46 .

[0059] In addition, such as Figure 1 , Fig.12 and Fig.13 As shown, the conveying device 2 52 installed inside the equipment mounting frame 2 51 is used to convey the bearing shell 2 after the needle assembly process is completed. The two guide bent plates 2 53 fixedly installed on the top of the equipment mounting frame 2 51 limit the bearing shell 2. The material conveying pipeline 54 fixedly installed between the equipment mounting frame 2 51 and the supporting bottom plate 41 is used for the transfer of the bearing shell 2. A top plate 58 is provided on one side of the bottom of the shielding plate 55 close to the fixed frame 2 56. One end of the top plate 58 is fixedly connected to the piston end of the electric push rod 2 57. The electric push rod 57 fixedly installed on the feeding pipe 54 drives the ejecting plate 58 to move. When the ejecting plate 58 leaves the bottom of the baffle plate 55, the bottom of the baffle plate 55 installed on the fixed frame 56 loses support and flips over; when the ejecting plate 58 moves toward the baffle plate 55, the contact end of the ejecting plate 58 and the baffle plate 55 is set to a curved surface to reduce the friction force generated when the ejecting plate 58 lifts the baffle plate 55. Finally, the ejecting plate 58 lifts the baffle plate 55 to reset it and seal the bottom of the feeding pipe 54.

[0060] In addition, such as Figure 6 and Figure 7 As shown, a transmission cross plate 417 with holes is sleeved on the outside of a damper 419. The up and down movement of the transmission cross plate 417 will not affect the rotation of a gear 420. A fixing frame 418 is fixedly installed between the damper 419 and the supporting base plate 41. The fixing frame 418, which is L-shaped as a whole, fixes the damper 419 so that the piston end of the damper 419 can be extended under force.

[0061] In addition, such as Figure 1 , Figure 4 and Fig.12 As shown, two telescopic rods 414 are fixedly installed at the bottom end of the supporting base plate 41, and the bottom ends of the telescopic rods 414 and the multi-stage telescopic pneumatic cylinder three 413 are fixedly connected with a fixed plate 415, and the fixed plate 415 is fixedly connected with the curved surface block one 416. When the multi-stage telescopic pneumatic cylinder three 413 works to control the up and down position of the curved surface block one 416, the telescopic rods 414 can support and guide the curved surface block one 416 to ensure that the curved surface block one 416 can only move up and down.

[0062] In addition, such as Figure 8 , Fig. 9 and Fig.14 As shown, two mounting rings are fixedly installed between the outer side of the hydraulic telescopic rod 431 and the circular bracket 421, a friction block 432 is fixedly installed on the piston end of the hydraulic telescopic rod 431, a guide frame 434 and a plurality of return springs 433 are fixedly installed on one side of the friction block 432, the plurality of return springs 433 are fixedly connected to adjacent mounting rings, the guide frame 434 penetrates the adjacent mounting rings and can move, and the guide frame 434 cooperates with the mounting ring to limit the movement direction of the friction block 432 to prevent the friction block 432 from rotating, and when the hydraulic pressure inside the liquid storage tank 428 and the hydraulic telescopic rod 431 is restored, the plurality of return springs 433 rebound to apply a return force to the friction block 432 to return the friction block 432.

[0063] In addition, such as Figure 6 , Figure 7 and Figure 8 As shown, since the rotating ring 1 422 is rotatably connected to the circular bracket 421, the rotating ring 2 424 is rotatably installed together with the rotating ring 3 425 that presses the elastic liquid storage member 430, during the rotation of the circular bracket 421, the multiple dampers 2 423 installed between the rotating ring 1 422 and the rotating ring 2 424 and the elastic liquid storage member 430 pressed by the rotating ring 3 425 are subjected to relatively small rotational forces, which do not reach a state of damaging the rotating ring 2 424 and the elastic liquid storage member 430.

[0064] In addition, such as Figure 3 As shown, a receiving groove 47 is provided on one side of the U-shaped frame 42, and the pushing rack 410 can be received inside the receiving groove 47 to prevent the pushing rack 410 from affecting the movement of the pushing rack 15.

[0065] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
