Specific implementation manners

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 , Figure 4 and Figure 5, an embodiment provided by the present utility model: a high-power and high-speed electric drive test bench, including a working frame 1. The working frame 1 is the structure with the strongest bearing capacity in the overall device, which can enable subsequent workpieces to be installed and fixed on its top. Support legs are fixedly connected to the four peripheries of the bottom of the working frame 1, and through the support legs, the working frame 1 can be made more stable. A hydraulic cylinder 2 is fixedly connected to the rear end of the top of the working frame 1, and the hydraulic cylinder 2 can drive subsequent workpieces to lift. A plurality of telescopic rods 3 are fixedly connected to the top of the working frame 1. The telescopic rods 3 are designed to provide support force for subsequent workpieces and can achieve the effect of telescoping at the same time. The driving end of the hydraulic cylinder 2 is fixedly connected to an adjusting frame 4. Through the hydraulic cylinder 2, the adjusting frame 4 can be driven to lift. The tops of the plurality of telescopic rods 3 are respectively fixedly connected to the bottom of the adjusting frame 4, and the telescopic rods 3 can provide support force for the adjusting frame 4, making it more stable during lifting;

[0033] Chutes 5 are respectively opened in the left and right sides of the adjusting frame 4. The chutes 5 can drive subsequent workpieces to move. A support rod 6 is fixedly connected to the top of the working frame 1. The top of the support rod 6 is rotatably connected to a workbench 7. Through the support rod 6, the workbench 7 can be rotated. Adjusting components for measuring the angles of processed objects are fixedly connected to the left and right sides of the top of the workbench 7. The adjusting components include two driving blocks 9. The tops of the two driving blocks 9 are fixedly connected to the left and right ends of the bottom of the workbench 7. Through the driving blocks 9, the workbench 7 can be driven. An adjusting rod 10 is rotatably connected to the inside of the driving block 9. The adjusting rod 10 can rotate inside the driving block 9. The far ends of the two adjusting rods 10 are respectively fixedly connected to a slider 11. The far ends of the sliders 11 are slidably connected to the inside of the chutes 5. By pulling the adjusting frame 4 to move through the hydraulic cylinder 2, the sliders 11 can move inside the chutes 5, enabling the workbench 7 to achieve the effect of angle adjustment. Linking blocks 8 are fixedly connected to both sides of the bottom of the workbench 7. The near ends of the two adjusting rods 10 are respectively fixedly connected to the far ends of the two linking blocks 8. The linking blocks 8 can make the angle adjustment more convenient;

[0034] Refer to Figures 1 to 3, a cylinder 12 is fixedly connected to the front end of the top of the workbench 7. The driving end of the cylinder 12 is fixedly connected to a push plate 13. The push plate 13 can be pushed to move by the cylinder 12. The bottom of the push plate 13 is slidably connected to the top of the workbench 7, and the push plate 13 can move on the top of the workbench 7, enabling the push plate 13 to move stably. On the left and right sides of the inner part of the rear end of the workbench 7, bolts 14 are fixedly connected. A collar 15 is fixedly connected to the outside of the bolt 14. The bolt 14 can fix the collar 15. The bottoms of the two collars 15 are fixedly connected to the rear end of the top of the workbench 7, and the workbench 7 can provide an additional fixing point for the collar 15. A clamping block 16 is rotatably connected to the outside of the bolt 14, and the clamping block 16 can rotate on the outside of the bolt 14. A nut 17 is threadedly connected to the top end of the outside of the bolt 14. By adjusting the nut 17 on the outside of the bolt 14, the clamping block 16 can be replaced. The top of the collar 15 is in contact with the bottom of the clamping block 16, and the bottom of the nut 17 is in contact with the top of the clamping block 16;

[0035] The collar 15 and the nut 17 limit the clamping block 16, so that the clamping block 16 will not shake during clamping. A connecting rod 18 is fixedly connected to the inner rear end of the nut 17. The adjacent ends of the two connecting rods 18 are fixedly connected to a spring 19. The connecting rod 18 can fix the spring 19. A connecting frame 20 is fixedly connected to the rear end of the workbench 7. A detector 21 is fixedly connected to the top of the connecting frame 20. The connecting frame 20 can fix the detector 21, and can drive the detector 21 instrument to adjust during angle adjustment. The cylinder 12 is started to push the push plate 13 to move. During the movement of the push plate 13, the object can be moved. When one end of the object contacts the two clamping blocks 16, it is fixed. At this time, the driving end of the object is placed into the detector 21 to achieve the detection effect.

[0036] Working principle: When it is necessary to clamp and fix the workpiece to be tested, first place the object on the top of the workbench 7. Then, start the cylinder 12 to push the push plate 13 to move. During the movement of the push plate 13, the object can be moved. When one end of the object contacts the two clamping blocks 16, the adjacent ends of the two clamping blocks 16 can be moved to achieve the effect of clamping and fixing. At the same time, the bolt 14 fixed inside the workbench 7 enables the clamping block 16 to rotate, and the collar 15 and the nut 17 limit the clamping block 16 to prevent the position deviation of up and down movement during clamping of the object, resulting in an unsatisfactory clamping effect. The connecting rod 18 fixed to the rear end of the clamping block 16 can fix the spring 19. When the cylinder 12 retracts the push plate 13, the two clamping blocks 16 will be pulled back by the spring 19 and reset.

[0037] When the angle of the clamped object needs to be adjusted, first start the hydraulic cylinder 2 to pull the adjusting frame 4 to descend. When the adjusting frame 4 descends, it can drive the slider 11 to slide inside the chute 5. While the slider 11 is moving, it can drive the adjusting rod 10 to rotate. An actuating block 9 is sleeved outside the adjusting rod 10, causing the two actuating blocks 9 to deviate in angle, and then the workbench 7 can be driven to adjust the angle. When the angle of the workbench 7 changes, the angle of the object on the top can be adjusted simultaneously. At this time, insert the driving end of the object into the detector 21 for detection.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
