Description

Technical Field

[0001] This utility model mainly relates to the field of torque-limiting vibration damper technology, specifically to a torque-limiting vibration damper automatic torque detection and zero-return device. Background Technology

[0002] Torsion dampers are important mechanical components. When vehicles or machinery are in operation, wheels and related parts are subjected to various external forces, resulting in vibration and noise. Torsion dampers reduce these vibrations and noises through their unique structure; they reduce the vibration and noise generated by vehicles or machinery during operation by limiting the torsional angle and frictionally transmitting torque. Their wide range of applications and excellent performance characteristics make them an indispensable part of modern industry and transportation.

[0003] After the torsion damper is manufactured, it needs to undergo damping testing and zeroing adjustment. This is mainly achieved through a zeroing mechanism, which can perform forward and reverse rotation and torque testing on the torsion damper. Forward and reverse rotation can break in the rough parts between the friction plate and the torsion damper, thereby improving the damping effect of the torsion damper after it leaves the factory. Finally, a zeroing reset operation is performed to facilitate the later installation of the torsion damper. Then, a torque test is performed. After the torque test, the flywheel mounting hole and the clearance hole need to be aligned and zeroed to facilitate subsequent installation.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] Currently, when the zeroing mechanism is working on the torsion damper, it usually involves manually loading the torsion damper from the conveyor belt. After the zeroing test is completed, the qualified torsion damper is placed on the conveyor belt at the discharge point. This process is quite cumbersome, and the overall weight of the torsion damper is also quite heavy, making manual loading and unloading difficult. There is also a safety risk if there is a collision.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] 1. The technical problem to be solved by the utility model:

[0008] This utility model provides an automatic torque detection and zero-return device for a torque-limiting vibration damper, which solves the technical problems existing in the background art.

[0009] 2. Technical Solution:

[0010] To achieve the above objectives, the technical solution provided by this utility model is as follows: an automatic torque detection and zero-return device for a torsion damper, comprising a working box, a rotating mechanism connected to the top of the working box, a rotating platform detachably connected to the top of the rotating mechanism, lifting platforms detachably connected to the four sides of the rotating platform, lifting grooves on the sides of the lifting platforms, clamping and transferring mechanisms matched to the lifting grooves, a detection and zero-return mechanism provided on the side of the working box, a support tray provided on the detection and zero-return mechanism, a torsion damper placed on the top of the support tray, a first conveyor platform provided on the opposite side of the detection and zero-return mechanism, and a second conveyor platform provided on the side of the first conveyor platform. When the device is in operation, the torsion damper to be detected can be placed on the first conveyor platform, and the first conveyor platform and the rotating mechanism on the side cooperate intermittently. The system performs conveying and transfer operations on the torsion damper. When the torsion damper on the first conveyor platform is conveyed to the preset position, the corresponding clamping and transfer mechanism at the top moves to the preset position under the action of the lifting platform to clamp the torsion damper. After clamping, the lifting platform moves the torsion damper up to the preset position. Then, the rotating mechanism rotates a predetermined angle so that the torsion damper is located on the top of the support tray of the detection and zeroing mechanism. The lifting platform moves the torsion damper down to place it on the support tray. Then, the detection and zeroing mechanism can perform detection and zeroing operations on it. After completion, the clamping and transfer mechanism descends again to remove the torsion damper. The torsion damper is rotated by a preset angle and sent to the second conveyor platform for discharge. The whole process is highly automated and efficient, reducing labor costs.

[0011] The rotating mechanism can be a combination of a rotary motor and a rotary table, which is existing technology and will not be elaborated here. The first and second conveyor tables can also use similar conveyor belts for conveying operations. It should be noted that in order to ensure the smooth clamping of the torsion damper, the angle of the torsion damper placed on the first conveyor table needs to be coordinated with the clamping and transfer mechanism. The detection and zeroing mechanism is the current existing technology, which is used to perform torque detection, break-in and zeroing operations on the torsion damper.

[0012] Furthermore, the lifting platform includes an L-shaped support platform, with two sets of concave grooves symmetrically arranged on the side of the L-shaped support platform. The concave grooves are provided with connecting holes. The lifting groove is opened on the side of the L-shaped support platform. Lifting cylinders are symmetrically arranged on the top of the lifting groove. The bottom of the lifting cylinder is connected to the clamping and transfer mechanism.

[0013] Furthermore, the clamping and transfer mechanism includes an irregularly shaped lifting plate, which is slidably connected to the lifting groove and its top is connected to the lifting cylinder. The irregularly shaped lifting plate has a clamping groove on its side, and clamping plates are symmetrically arranged in the clamping groove. A drive motor is provided on the side of the clamping groove, and the drive motor is connected to a rotating lead screw. The rotating lead screw is matched and connected to the clamping plate.

[0014] Furthermore, the outer side of the clamping plate has a folded structure, and the inner side of the folded structure is symmetrically provided with trapezoidal support plates, the ends of which are connected to L-shaped clamping plates.

[0015] Furthermore, the support tray has two sets of concave slots symmetrically opened on both sides, the concave slots corresponding to the L-shaped card plate, the support tray has a through hole in the middle, and the outside of the through hole is provided with a limiting protrusion in an annular pattern, the limiting protrusion corresponding to the flywheel mounting hole of the torsion damper.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This utility model is reasonably designed. When detecting and returning the torque of the torsion damper to zero, the rotating table, in conjunction with the lifting clamping and transfer mechanism, automatically loads and unloads the torsion damper, reducing labor costs, simplifying the detection and zeroing process, and also reducing the probability of accidents when operators move the torsion damper.

[0019] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

[0029] See attached document Figure 1-3An automatic torque detection and zero-return device for a torsion damper includes a work box 1. A rotating mechanism is connected to the top of the work box 1. A rotating platform 2 is detachably connected to the top of the rotating mechanism. Lifting platforms 3 are detachably connected to the four sides of the rotating platform 2. Lifting platforms 3 have lifting grooves 4 on their sides, which are matched with clamping and transferring mechanisms 5. A detection and zero-return mechanism 6 is provided on the side of the work box 1. A support tray 7 is provided on the detection and zero-return mechanism 6, and a torsion damper is placed on the top of the support tray 7. A first conveyor platform 8 is provided on the opposite side of the detection and zero-return mechanism 6, and a second conveyor platform 9 is provided on the side of the first conveyor platform 8. When the device is working, the torsion damper to be detected can be placed on the first conveyor platform 8. The first conveyor platform 8 and the rotating mechanism on the side cooperate to intermittently reduce the torsion. The device performs conveying and transfer operations. When the torsion damper on the first conveyor table 8 is conveyed to the preset position, the corresponding clamping and transfer mechanism 5 at the top moves to the preset position under the action of the lifting table 3 to clamp the torsion damper. After clamping, the torsion damper is moved up to the preset position under the action of the lifting table 3. Then, the rotating mechanism rotates at a predetermined angle so that the torsion damper is located on the top of the support tray 7 of the detection and zeroing mechanism 6. The lifting table 3 drives the torsion damper to descend and place it on the support tray 7. Then, the detection and zeroing mechanism 6 can perform detection and zeroing operations on it. After completion, the clamping and transfer mechanism 5 descends again to take out the torsion damper. The torsion damper is rotated at a preset angle and sent to the second conveyor table 9 for discharge. The whole process is highly automated and efficient, reducing labor costs.

[0030] The rotating mechanism can be a combination of a rotary motor and a rotary table, which is existing technology and will not be described in detail. The first conveyor table 8 and the second conveyor table 9 can also use similar conveyor belts for conveying operations. It should be noted that in order to ensure the smooth clamping of the torsion damper, the angle of the torsion damper placed on the first conveyor table 8 needs to be coordinated with the clamping and transfer mechanism 5. The detection and zeroing mechanism 6 is the current existing technology, which is used to perform torque detection, break-in and zeroing operations on the torsion damper.

[0031] The lifting platform 3 includes an L-shaped support platform 31. The L-shaped support platform 31 has two sets of concave grooves 32 symmetrically arranged on its side. The concave grooves 32 are provided with connecting holes. The L-shaped support platform 31 has a lifting groove 4 on its side. The top of the lifting groove 4 is symmetrically provided with lifting cylinders 33. The bottom of the lifting cylinders 33 is connected to the clamping and transferring mechanism 5. The lifting platform 3 can perform lifting and lowering operations on the clamping and transferring mechanism 5. When it is necessary to lower the platform to pick up or drop materials, the lifting cylinders 33 extend and retract, thereby driving the clamping and transferring mechanism 5 at the bottom to perform lifting and lowering operations. The connecting hole can be detachably connected to the rotating platform 2 by screws, thereby installing the L-shaped support platform 31 on the rotating platform 2.

[0032] The clamping and transfer mechanism 5 includes a shaped lifting plate 51, which is slidably connected to the lifting groove 4 and its top is connected to the lifting cylinder 33. The side of the shaped lifting plate 51 has a clamping groove 52, and clamping plates 53 are symmetrically arranged in the clamping groove 52. A drive motor 54 is provided on the side of the clamping groove 52, and the drive motor 54 is connected to a rotating lead screw 55. The rotating lead screw 55 is matched and connected to the clamping plates 53. When clamping and picking up materials is required, the drive motor 54 will drive the rotating lead screw 55 to rotate. When the rotating lead screw 55 rotates, it will drive the two clamping plates 53 to move closer to each other or separate from each other, thereby achieving a clamping effect. The shaped lifting plate 51 can perform lifting and lowering operations in the lifting groove 4 under the action of the lifting cylinder 33.

[0033] The outer side of the clamping plate 53 has a folded structure, and the inner side of the folded structure is symmetrically provided with trapezoidal support plates 56. The ends of the trapezoidal support plates 56 are connected to L-shaped clamping plates 57. There are a total of four L-shaped clamping plates 57 on the two clamping plates 53. When the clamping plates 53 are close to each other, they can clamp and lift the torsion damper.

[0034] The support tray 7 has two sets of concave slots 71 symmetrically opened on both sides, and the concave slots 71 correspond to the L-shaped clamping plate 57. A through hole 72 is opened in the middle of the support tray 7, and a limiting protrusion 73 is arranged in a ring around the outside of the through hole 72. The limiting protrusion 73 corresponds to the flywheel mounting hole of the torsion damper. Since the L-shaped clamping plate 57 is designed at an angle, the concave slots 71 are smaller than the size of the L-shaped clamping plate 57. When the torsion damper is placed, the clamping plate 53 descends from the top, and the L-shaped clamp... The slot is located in the concave slot 71. The clearance hole of the torsion damper matches and connects with the bottom limiting protrusion 73. Then the L-shaped clamping plate 57 opens outward so that the torsion damper can be placed on the support tray 7. When the torsion damper needs to be removed, the L-shaped clamping plate 57 descends and clamps inward to enter the L-shaped slot to achieve the effect of clamping and lifting. The through hole 72 is equipped with the connecting spline of the detection and zeroing mechanism 6. After the torsion damper is placed on the support tray 7, the subsequent detection and zeroing operation can be carried out.

[0035] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
