Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] like Figure 1-5 As shown, the present invention proposes a tractor chassis dual-machine loading break-in test bench, including a workbench 1, a collection trough 2 on the top of the workbench 1, a support mechanism 3 on the top of the workbench 1, and a filter mechanism 4 inside the collection trough 2.
[0027] In this utility model, the tractor chassis can be supported by the workbench 1 and the support mechanism 3. At the same time, the support can be adjusted according to the different tractor ground surfaces, which improves the applicability of the break-in test bench. The break-in oil can be collected and filtered by the collection tank 2 and the filter mechanism 4, which facilitates the removal of impurities brought out by the break-in oil during the break-in process, thereby facilitating the recycling of the break-in oil and saving a lot of resources.
[0028] like Figure 1-4As shown, in an optional embodiment, the support mechanism 3 includes a fixed box 31, two threaded sleeves 32, two threaded rods 33, a drive assembly 34, a displacement plate 35, a support plate 36, and a limiting assembly 37. The fixed box 31 is located on the top of the workbench 1. The two threaded sleeves 32 are rotatably connected to the left side wall of the inner cavity of the fixed box 31, and the other ends of the two threaded sleeves 32 extend to the right side of the fixed box 31. The two threaded rods 33 are threadedly connected to the inside of the two threaded sleeves 32. The drive assembly 34 is located inside the fixed box 31 and is connected to the threaded sleeves 32 to drive the threaded sleeves 32 to rotate. The displacement plate 35 is located at the right end of the two threaded rods 33. The support plate 36 is located at the bottom right side of the displacement plate 35. The limiting assembly 37 is located at the bottom of the support plate 36 to support and limit the support plate 36.
[0029] When a break-in test is required on the tractor chassis, the support plate 36 can support the tractor chassis. When supporting tractor chassis of different sizes, the drive assembly 34 can drive the two threaded sleeves 32 to rotate. Under the action of the displacement plate 35, the two threaded rods 33 will not rotate. Therefore, when the two threaded sleeves 32 rotate, under the action of thread thrust, the two threaded sleeves 32 will drive the two threaded rods 33 to move to the left or right respectively. The two threaded rods 33 will drive the displacement plate 35 to move to the left or right. The displacement plate 35 will drive the support plate 36 to move to the left or right, thereby adjusting the position of the support plate 36. When adjusting the position of the support plate 36, the limiting assembly 37 can guide and support the support plate 36 to ensure the stability of the support plate 36 when moving or supporting.
[0030] In this embodiment, there are two sets of support mechanisms 3. Both sets of support mechanisms 3 are located on the top of the workbench 1 and are symmetrically distributed. When the positions of the two support plates 36 are adjusted, the distance between the two support plates 36 can be adjusted. The two support plates 36 can support the tractor chassis of different sizes. After supporting the tractor chassis, the tractor chassis can be run-in. The running-in oil during the running-in process will fall directly into the collection tank 2 for collection.
[0031] like Figure 3As shown, in an optional embodiment, the drive assembly 34 includes a dual-head servo motor 341, two rotating rods 342, two worm gears 343, and two worm wheels 344. The dual-head servo motor 341 is located on the inner bottom wall of the fixed box 31. The two rotating rods 342 are respectively located on the two output shafts of the dual-head servo motor 341. The opposite ends of the two rotating rods 342 are rotatably connected to the front and rear side walls of the inner cavity of the fixed box 31, respectively. The two worm gears 343 are respectively located on the outer side of the two rotating rods 342, and the two worm wheels 344 are respectively located on the outer side of the two threaded sleeves 32. The two worm gears 343 mesh with the two worm wheels 344.
[0032] When the dual-head servo motor 341 is started, the two output shafts of the dual-head servo motor 341 will drive the two rotating rods 342 to rotate, the two rotating rods 342 will drive the two worm gears 343 to rotate, the two worm gears 343 will drive the two meshing worm wheels 344 to rotate, and the two worm wheels 344 will drive the two threaded sleeves 32 to rotate.
[0033] The two worms 343 and the two worm wheels 344 are symmetrically distributed, so the two threaded sleeves 32 rotate in opposite directions. The inner threads of the two threaded sleeves 32 and the outer threads of the two threaded rods 33 are also opposite, so that when the two threaded sleeves 32 rotate, they will drive the two threaded rods 33 to move horizontally in the same direction.
[0034] like Figure 1 , Figure 2 and Figure 4 As shown, in an optional embodiment, the limiting component 37 includes two supporting rollers 371 and two limiting grooves 372. The two supporting rollers 371 are both located at the bottom of the supporting plate 36, and the two limiting grooves 372 are both located at the top of the worktable 1. The outer sides of the two supporting rollers 371 are respectively rolledly connected to the inner bottom wall of the two limiting grooves 372.
[0035] During the movement of the support plate 36, the support plate 36 will drive the two support rollers 371 to roll inside the two limiting grooves 372 respectively. While ensuring that the support plate 36 can move stably, it can also provide stable support for the support plate 36, thereby ensuring that the support plate 36 can provide stable support for the tractor chassis.
[0036] like Figure 1 and Figure 4As shown, in an optional embodiment, the filtering mechanism 4 includes a support frame 41, a filter plate 42, two handles 43, and a guide assembly 44. The support frame 41 is located inside the collection tank 2, the filter plate 42 is placed on top of the support frame 41, and the filter plate 42 is adapted to the collection tank 2. Both handles 43 are located on top of the filter plate 42, and the guide assembly 44 is located on the outside of the filter plate 42 for guiding the filter plate 42.
[0037] During the break-in test of the tractor, some of the break-in oil will fall directly into the collection tank 2. During the break-in process, the break-in oil will contain some metallic impurities. When the break-in oil enters the collection tank 2, it will be filtered by the filter plate 42 to remove the impurities. The filtered break-in oil can be recycled. After the break-in test is completed, the two support plates 36 are moved to a position where they do not obstruct the top of the collection tank 2. Then, the filter plate 42 can be pulled upward by the two handles 43 to remove it from the collection tank 2. This makes it easy to clean, repair, or replace the filter plate 42, ensuring its filtering effect.
[0038] like Figure 1 and Figure 4 As shown, in an optional embodiment, the guide assembly 44 includes two guide grooves 441 and two guide blocks 442. The two guide grooves 441 are respectively opened on the left and right side walls of the inner cavity of the collection tank 2. The tops of the two guide grooves 441 are connected to the outside. The two guide blocks 442 are respectively disposed on the left and right sides of the filter plate 42. The two guide blocks 442 are slidably connected to the inside of the two guide grooves 441.
[0039] When installing the filter plate 42, the filter plate 42 can be guided by two guide grooves 441 and two guide blocks 442 to ensure the stability of the filter plate 42 during installation and prevent the filter plate 42 from shifting after installation.
[0040] like Figure 1 As shown, in an optional embodiment, a controller 5 is provided on the front of the workbench 1, and a discharge pipe 6 extending into the collection tank 2 is provided on the front of the workbench 1, with a valve provided inside the discharge pipe 6.
[0041] The dual-head servo motor 341 is electrically connected to the controller 5. The controller 5 can control the dual-head servo motor 341. The discharge pipe 6 is located below the filter plate 42. The filter oil in the collection tank 2 can be discharged through the discharge pipe 6 and the valve, which facilitates its recycling.
[0042] Working principle:
[0043] This tractor chassis dual-load break-in test bench, when in use, activates the dual-head servo motor 341. Under the transmission action of the rotating rod 342 and worm gear 343, the two support plates 36 can move to opposite sides or back sides, thereby adjusting the distance between the two support plates 36. When the distance between the two support plates 36 is adapted to the length of the tractor chassis, the tractor chassis can be placed on top of the two support plates 36, and then the break-in test of the tractor chassis can be carried out. During the break-in process, some break-in oil will fall into the collection tank 2 and be filtered by the filter plate 42. After the break-in test is completed, the two support plates 36 are moved to a position where they do not obstruct the top of the collection tank 2. Then, the filter plate 42 can be pulled upward by the two handles 43 to remove the filter plate 42 from the collection tank 2, making it convenient for cleaning, maintenance or replacement of the filter plate 42, ensuring the filtration effect of the filter plate 42. The filtered break-in oil in the collection tank 2 can be discharged through the discharge pipe 6 and valves, making it convenient for recycling.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
