Description

Technical Field

[0001] This utility model relates to the field of testing platform technology, and in particular to an instrument and meter repair and testing platform. Background Technology

[0002] Instrumentation maintenance and testing platforms are specialized support devices used in electronics, power, scientific research, and other fields to provide maintenance, calibration, and functional testing for various instruments and meters. Their core function is to provide a stable operating plane and diverse testing environments for the instruments under maintenance through adjustable mechanical structures and integrated electrical testing modules.

[0003] Current instrument and meter maintenance and testing platforms with tilt angle adjustment functions have significant shortcomings in multi-directional adjustment capabilities. Traditional platforms typically use a single tilt angle adjustment mechanism. This single adjustment mode leads to the following problems: when maintenance requires viewing the instrument display interface from different angles (such as curved screen instruments or multi-directional interface instruments), maintenance personnel need to frequently disassemble and reinstall the instruments, which not only interrupts the maintenance process but may also cause the instrument interfaces to loosen or the fixing structure to wear due to repeated disassembly and reassembly, affecting the accuracy of maintenance. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an instrument and meter maintenance and testing platform to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an instrument maintenance and testing platform, including a base frame. Two symmetrically arranged first cylinders are fixedly connected to the inner wall of the base frame. A lifting plate is fixedly connected to the output ends of the two first cylinders. A connecting rod is fixedly connected to the top surface of the lifting plate. A rotating plate is rotatably connected to the outer surface of the connecting rod. A support plate is fixedly connected to the bottom surface of the lifting plate. Two symmetrically arranged second cylinders are fixedly connected to one side of the support plate. A drive plate is fixedly connected to the output ends of the two second cylinders. Two symmetrically arranged transmission rods are rotatably connected between the drive plate and the rotating plate. Both transmission rods are slidably connected to the lifting plate. A gear disk is rotatably connected to one side of the rotating plate via a bearing. Two symmetrically arranged third cylinders are embedded in the top surface of the gear disk. A clamping plate is fixedly connected to the output end of each third cylinder. Both clamping plates are slidably connected to the gear disk. An L-shaped bracket is fixedly connected to the top surface of the rotating plate. A threaded post is threadedly connected to one side of the L-shaped bracket. A toothed plate is rotatably connected to one end of the threaded post via a bearing. The toothed plate meshes with the gear disk.

[0007] Preferably, in any of the above solutions, the top surface of the lifting plate has two symmetrically arranged connecting slots, and both transmission rods are slidably connected to the lifting plate through the connecting slots.

[0008] Preferably, in any of the above solutions, the bottom surface of the lifting plate is fixedly connected with a plurality of symmetrically arranged guide rods, and the plurality of guide rods are slidably connected to the bottom frame.

[0009] Preferably, in any of the above solutions, the drive plate is slidably connected to the lifting plate, and the lifting plate is parallel to the bottom frame.

[0010] Preferably, in any of the above solutions, two symmetrically arranged limiting posts are fixedly connected to the side of the toothed plate near the threaded post, and both limiting posts are slidably connected to the L-shaped bracket.

[0011] Preferably, one side of the rotating plate has a through-hole, and the rotating plate is rotatably connected to the connecting rod through the through-hole.

[0012] Preferably, in any of the above embodiments, the bottom surface of the toothed plate is in contact with the top surface of the rotating plate, and the toothed plate is adapted to the gear tooth pitch of the gear disk.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Addressing the shortcomings of traditional single-adjustment platforms, this device constructs a multi-dimensional adjustment system through a combination of multiple cylinders and gear transmission. The first cylinder drives the lifting plate to move up and down, achieving platform height adjustment; the second cylinder pushes the drive plate, which in turn drives the rotating plate to swing around the connecting rod via a transmission rod, completing the pitch angle adjustment; the threaded column on the rotating plate meshes with the gear plate and gear disk, and rotating the threaded column causes the gear disk to drive the clamped instrument to rotate horizontally. Combined with the clamping plate driven by the third cylinder, the pitch, roll, and yaw angles of the instrument can be precisely adjusted. For example, when repairing curved screen instruments, there is no need to disassemble the instrument. By adjusting the pitch angle of the rotating plate and the rotation angle of the gear disk, the display interface can be observed from different angles, avoiding loosening of the interface due to frequent disassembly and assembly, and ensuring repair accuracy and process continuity.

[0015] 2. The guide rod and connecting groove design of the device ensures structural stability during multi-dimensional adjustments. The guide rod is slidably connected to the base frame, providing stable guidance for the up-and-down movement of the lifting plate and preventing swaying. The connecting groove constrains the sliding trajectory of the transmission rod, making the pitch angle adjustment of the rotating plate smoother when the second cylinder pushes the drive plate. At the same time, the sliding cooperation between the limit post and the L-shaped bracket prevents the gear plate from shifting when the adjustment gear disk rotates, ensuring the accuracy of instrument posture adjustment. This linkage design allows maintenance personnel to quickly adjust the instrument to the optimal maintenance position. For example, when testing multi-interface instruments, by simultaneously adjusting the height, angle, and rotation direction, the functional tests of each interface can be completed at once, reducing adjustment time, improving maintenance efficiency, and the stable structure can avoid test data deviations caused by the shaking of the adjustment mechanism.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 5As shown, an instrument maintenance and testing platform includes a base frame 1. Two symmetrically arranged first cylinders 2 are fixedly connected to the inner wall of the base frame 1. A lifting plate 3 is fixedly connected to the output ends of the two first cylinders 2. A connecting rod 4 is fixedly connected to the top surface of the lifting plate 3. A rotating plate 5 is rotatably connected to the outer surface of the connecting rod 4. A support plate 6 is fixedly connected to the bottom surface of the lifting plate 3. Two symmetrically arranged second cylinders 7 are fixedly connected to one side of the support plate 6. A drive plate 8 is fixedly connected to the output ends of the two second cylinders 7. Two symmetrically arranged transmission plates rotatably connect the drive plate 8 and the rotating plate 5. Rod 9, both transmission rods 9 are slidably connected to lifting plate 3. A gear disk 10 is rotatably connected to one side of rotating plate 5 via bearing. Two symmetrically arranged third cylinders 11 are embedded in the top surface of gear disk 10. A clamping plate 12 is fixedly connected to the output end of each third cylinder 11. Both clamping plates 12 are slidably connected to gear disk 10. An L-shaped bracket 13 is fixedly connected to the top surface of rotating plate 5. A threaded post 14 is threadedly connected to one side of L-shaped bracket 13. A toothed plate 15 is rotatably connected to one end of threaded post 14 via bearing. The toothed plate 15 meshes with gear disk 10.

[0024] As an optional technical solution of this utility model, two symmetrically arranged connecting grooves 16 are opened through the top surface of the lifting plate 3. Both transmission rods 9 are slidably connected to the lifting plate 3 through the connecting grooves 16. When the second cylinder 7 drives the drive plate 8 to move, the transmission rod 9 slides in the connecting groove 16, constraining its movement trajectory and preventing the offset when the rotating plate 5 swings. This makes the adjustment process of the instrument pitch angle smoother, ensures the structural stability during multi-dimensional adjustment, and prevents the instrument attitude adjustment error caused by the shaking of the transmission rod 9.

[0025] As an optional technical solution of this utility model, the bottom surface of the lifting plate 3 is fixedly connected with several symmetrically arranged guide rods 17. The guide rods 17 are all slidably connected to the bottom frame 1. When the first cylinder 2 pushes the lifting plate 3 to move up and down, the guide rods 17 slide along the bottom frame 1 to prevent the lifting plate 3 from tilting or shifting, and to ensure that the instrument installed on the rotating plate 5 remains horizontal during the height adjustment process, thereby improving the operational reliability of the maintenance platform and reducing the impact of the shaking of the lifting mechanism on the instrument testing accuracy.

[0026] As an optional technical solution of this utility model, the drive plate 8 is slidably connected to the lifting plate 3, and the lifting plate 3 is parallel to the bottom frame 1. When the second cylinder 7 pushes the drive plate 8, the drive plate 8 slides along the lifting plate 3. With the constraint of the transmission rod 9 and the connecting groove 16, the pitch swing of the rotating plate 5 is always carried out in a plane parallel to the bottom frame 1, avoiding lateral displacement during pitch adjustment, ensuring the accuracy of the instrument pitch angle adjustment, and laying a stable foundation for multi-dimensional attitude adjustment.

[0027] As an optional technical solution of this utility model, two symmetrically arranged limiting posts 18 are fixedly connected to the side of the toothed plate 15 near the threaded post 14. Both limiting posts 18 are slidably connected to the L-shaped bracket 13. When the threaded post 14 is rotated to drive the toothed plate 15 to move, the limiting posts 18 slide along the L-shaped bracket 13 to prevent the toothed plate 15 from shifting or tilting, so that the toothed plate 15 and the gear disk 10 maintain stable meshing, avoid the gear disk 10 from being stuck due to the shaking of the toothed plate 15, and ensure the smoothness and accuracy of the horizontal rotation angle adjustment of the instrument.

[0028] As an optional technical solution of this utility model, a rotating hole 19 is provided through one side of the rotating plate 5. The rotating plate 5 is rotatably connected to the connecting rod 4 through the rotating hole 19. The rotating hole 19 provides the rotating axis of the rotating plate 5. When the transmission rod 9 is pushed by the drive plate 8, the rotating plate 5 can swing freely around the connecting rod 4 to meet the adjustment requirements of the instrument pitch angle. Moreover, the bearing design of the rotating hole 19 reduces rotational friction, making the pitch angle adjustment easier and improving the operation convenience of the maintenance platform.

[0029] As an optional technical solution of this utility model, the bottom surface of the toothed plate 15 is in contact with the top surface of the rotating plate 5, and the tooth pitch of the toothed plate 15 is adapted to the gear tooth pitch of the gear disk 10. When the toothed plate 15 moves close to the top surface of the rotating plate 5, its tooth pitch is precisely matched with the gear disk 10, ensuring that when the threaded column 14 is rotated, the toothed plate 15 can smoothly drive the gear disk 10 to rotate, avoiding meshing slippage or jamming caused by tooth pitch deviation, making the horizontal rotation angle adjustment of the instrument more accurate, meeting the needs of instrument orientation fine adjustment during maintenance, and improving the coordination of multi-dimensional adjustment.

[0030] An instrument and meter maintenance and testing platform, the working principle of which is as follows:

[0031] 1): The first cylinder 2 drives the lifting plate 3 to move up and down, thereby adjusting the platform height; the second cylinder 7 pushes the drive plate 8, which in turn drives the rotating plate 5 to swing around the connecting rod 4 via the transmission rod 9, thereby adjusting the pitch angle.

[0032] 2): The threaded post 14 on the rotating plate 5 meshes with the toothed plate 15 and the gear disk 10. Rotating the threaded post 14 can cause the gear disk 10 to drive the clamped instrument to rotate horizontally.

[0033] 3) It can precisely adjust the pitch, roll, and yaw angles of the instrument. For example, when repairing a curved screen instrument, there is no need to disassemble the instrument. By adjusting the pitch angle of the rotating plate 5 and the rotation angle of the gear disk 10, the display interface can be observed from different positions.

[0034] In summary, this instrument maintenance and testing platform constructs a multi-dimensional adjustment system through a combination of multiple cylinders and gear transmission. The first cylinder 2 drives the lifting plate 3 to move up and down, realizing the adjustment of the platform height; the second cylinder 7 pushes the drive plate 8, which drives the rotating plate 5 to swing around the connecting rod 4 through the transmission rod 9, completing the pitch angle adjustment; the threaded column 14 on the rotating plate 5 meshes with the gear plate 15 and the gear disk 10. Rotating the threaded column 14 can make the gear disk 10 drive the clamped instrument to rotate horizontally. In conjunction with the clamping plate 12 driven by the third cylinder 11, the pitch, roll and yaw angles of the instrument can be precisely adjusted. For example, when inspecting curved screen instruments, there is no need to disassemble the instrument. By adjusting the pitch angle of the rotating plate 5 and the rotation angle of the gear disk 10, the display interface can be observed from different angles, avoiding loosening of the interface due to frequent disassembly and assembly, ensuring the accuracy and continuity of the inspection process. The guide rod 17 is slidably connected to the bottom frame 1, providing stable guidance for the up and down movement of the lifting plate 3 and preventing shaking. The connecting groove 16 constrains the sliding trajectory of the transmission rod 9, making the pitch angle adjustment of the rotating plate 5 more stable when the second cylinder 7 pushes the drive plate 8. At the same time, the sliding cooperation between the limit post 18 and the L-shaped bracket 13 prevents the gear plate 15 from shifting when adjusting the rotation of the gear disk 10, ensuring the accuracy of the instrument posture adjustment. This linkage design allows maintenance personnel to quickly adjust the instrument to the optimal maintenance position. For example, when testing multi-interface instruments, by simultaneously adjusting the height, angle, and rotation direction, the functional tests of each interface can be completed at one time, reducing adjustment time, improving maintenance efficiency, and the stable structure can avoid test data deviation caused by shaking of the adjustment mechanism.
