Description

Technical Field

[0001] This utility model relates to the field of experimental platform technology, and in particular to an experimental platform for testing mechanical transmission performance. Background Technology

[0002] Mechanical transmission performance testing benches are core equipment in the field of mechanical engineering used to test the efficiency, load-bearing capacity, stability and other key performance characteristics of various transmission systems such as gear transmission and belt transmission. They are widely used in mechanical product research and development, production quality inspection and teaching experiments.

[0003] Existing mechanical transmission performance testing benches have at least the following drawbacks:

[0004] 1. The protective structure design is rigid, and most experimental benches do not have dedicated protective devices. During the test, the flying of parts can easily cause safety hazards. Some experimental benches with protective structures have fixed and non-removable protective structures, which block the test area and affect the observation and operation of the mechanical transmission process.

[0005] 2. Insufficient shock absorption performance and inconvenient maintenance. The existing shock absorption components of the experimental platform are mostly fixedly connected to the main structure, resulting in limited shock absorption effect. The vibration generated during testing can easily affect the test accuracy. Furthermore, the disassembly and replacement of the shock absorption pads after aging is cumbersome and the maintenance cost is high.

[0006] 3. The existing experimental platform's protective components require separate external space for storage after disassembly, which can easily lead to clutter in the testing area.

[0007] Therefore, this utility model proposes a mechanical transmission performance testing platform to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mechanical transmission performance testing platform.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A mechanical transmission performance testing platform includes a support base, a worktable on the top surface of the support base, side baffles on both sides and the rear side of the support base, and several rectangular slots on both sides and the rear side of the support base. Several support plates are fixedly installed on one side of the side baffles at positions corresponding to the rectangular slots. The support plates and the inner wall dimensions of the rectangular slots are matched and movably connected. Several threaded slots are respectively opened on both sides and the rear side of the worktable. Several threaded holes are opened on one side of the side baffles. Locking bolts are threadedly connected to the inner circular wall of the threaded holes. The locking bolts are threadedly connected to the threaded slots. Several shock-absorbing pads are provided between the support base and the worktable.

[0011] As a further embodiment of this utility model, a threaded pipe seat is fixedly installed on the top surface of the shock-absorbing pad, and a plurality of circular grooves are opened on the top surface of the workbench. A connecting hole is opened at the bottom of the circular groove, and a second bolt is inserted into the connecting hole. The second bolt is threadedly connected to the threaded pipe seat.

[0012] As a further embodiment of this utility model, the top surface of the support base is provided with several circular through holes, and a threaded column seat is fixedly installed at the bottom of the shock-absorbing pad. The threaded column seat is movably sleeved with the circular through holes, and a nut is threadedly connected to the outer circular wall surface of the threaded column seat.

[0013] As a further embodiment of this utility model, flat washers are movably fitted onto the outer circular wall surfaces of the threaded column base and the second bolt, respectively.

[0014] As a further embodiment of this utility model, the inner circular wall of the circular groove is provided with threads, and the inner circular wall of the circular groove is threadedly connected with a threaded cap, the top surface of which is provided with a rectangular or cross groove.

[0015] As a further embodiment of this utility model, an elastic rubber ring is fixedly installed on the bottom surface of the threaded cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model, through its detachable side panel design, solves the defects of insufficient protection or fixed protective shielding in existing technologies. When protection is needed, it can be quickly installed to provide three-sided (or four-sided) shielding, preventing parts from flying off; when protection is not needed, it can be disassembled and stored inside the support base, clearing the space around the work surface and facilitating observation and operation, thus balancing protection and operational flexibility.

[0018] 2. This utility model effectively reduces vibration transmission during testing by using a shock-absorbing pad design between the support base and the worktable, ensuring testing accuracy and solving the problem of poor shock absorption in existing technologies. At the same time, the shock-absorbing pad is detachably connected by a threaded column base, a second bolt, and other structures. Combined with the protective design of the threaded cover, the replacement steps are simple, reducing maintenance difficulty and cost.

[0019] 3. The side panels of this experimental platform are stored inside the support base, avoiding external space occupation. The modular and detachable connection between the shock-absorbing pads, the workbench, and the support base further expands the adaptability of the experimental platform and improves the practicality and scenario compatibility of the equipment.

[0030] Reference Figures 1-6 A mechanical transmission performance testing platform includes a support base 1, a workbench 2 on the top surface of the support base 1, side baffles 3 on both sides and the rear side of the support base 1, and several rectangular grooves 4 on both sides and the rear side of the support base 1. Several support plates 5 are fixedly installed on one side of the side baffles 3 corresponding to the rectangular grooves 4. The inner wall dimensions of the support plates 5 and the rectangular grooves 4 are matched and they are movably connected. Several threaded grooves 6 are opened on both sides and the rear side of the workbench 2. Several threaded holes 8 are opened on one side of the side baffles 3. Locking bolts 7 are threadedly connected to the inner circular wall of the threaded holes 8. The locking bolts 7 are threadedly connected to the threaded grooves 6. Several shock-absorbing pads 17 are provided between the support base 1 and the workbench 2.

[0031] In this embodiment, a threaded tube seat 9 is fixedly installed on the top surface of the shock-absorbing pad 17. Several circular grooves 13 are opened on the top surface of the workbench 2. A connecting hole 14 is opened at the bottom of the circular groove 13. A second bolt 15 is inserted into the connecting hole 14 and is threadedly connected to the threaded tube seat 9. Several circular through holes 10 are opened on the top surface of the support base 1. A threaded column seat 11 is fixedly installed at the bottom of the shock-absorbing pad 17. The threaded column seat 11 is movably sleeved with the circular through hole 10. A nut 12 is threadedly connected to the outer circular wall of the threaded column seat 11. Flat washers are movably sleeved on the outer circular walls of the threaded column seat 11 and the second bolt 15, respectively. A thread is opened on the inner circular wall of the circular groove 13, and a threaded cover 16 is threadedly connected to the inner circular wall of the circular groove 13. A rectangular or cross groove is opened on the top surface of the threaded cover 16, and an elastic rubber ring is fixedly installed on the bottom surface of the threaded cover 16.

[0032] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: When the user uses the support base 1 and tests the transmission performance of the machine, the machine is installed through the mounting track groove on the top surface of the workbench 2. The installation method and the machine are existing mature technologies, and will not be described in detail here.

[0033] During testing, the side baffles 3 on both sides and the rear of the support base 1 provide three-sided protection, which can effectively prevent parts from splashing during the test. If a higher level of protection is required, a side baffle 3 can be added to the front of the support base 1 based on the same structural principle to form four-sided protection, which can adapt to different test scenario requirements.

[0034] Meanwhile, the shock-absorbing pads 17 are installed between the support base 1 and the workbench 2 to reduce vibration, effectively weakening the vibration transmitted to the support base 1 and the ground.

[0035] When it is necessary to replace the shock absorber 17, use a flathead or Phillips screwdriver to insert into the rectangular or Phillips groove on the top surface of the threaded cover 16 and unscrew it to remove it from the circular groove 13. Then, unscrew the second bolt 15 from the threaded tube seat 9. After disassembling the other parts, remove the worktable 2. At this time, the worktable 2 can be replaced so that it can be flexibly adjusted according to the test scenarios of different types of transmission systems such as gear transmission and belt transmission. Then, unscrew the nut 12 at the bottom of the support base 1 to release the bottom fixation of the shock absorber 17. Move the shock absorber 17 upward to drive the threaded column seat 11 out from the circular through hole 10 to complete the disassembly of the shock absorber 17. After replacing the shock absorber 17, reinstall and fix the worktable 2 in the above manner.

[0036] When the side baffle 3 needs to be removed without protection, first unscrew the locking bolt 7 from the threaded hole 8 and the threaded groove 6 to release the fixation between the side baffle 3 and the worktable 2; then move the side baffle 3 horizontally in the horizontal direction so that the support plate 5 can be pulled out from the rectangular groove 4, and the side baffle 3 can be removed; the removed side baffle 3 can be stored in the preset storage cavity inside the support base 1 to avoid occupying external space.

[0037] By disassembling and assembling the side baffle 3 and storing it inside the support base 1, it is convenient to clean up the space around the tabletop and to conduct mechanical observation, operation and testing.

[0038] The flat washer fitted on the outer circular wall of the threaded column seat 11 and the second bolt 15 can enhance the sealing and anti-slip properties of the connection and prevent the bolt from loosening due to long-term vibration; the elastic rubber ring on the bottom surface of the threaded cover 16 can fill the gap between the threaded cover 16 and the circular groove 13, which can play a role in dust prevention and waterproofing, and protect the internal structure of the connection hole 14.

[0039] It should be noted that the specific machinery used for the mechanical rotation performance test is existing technology and will not be described in detail here.
