Description
Technical Field
[0001] This utility model relates to the field of engine flywheel testing technology, and in particular to an engine flywheel surface performance testing device. Background Technology
[0002] The engine flywheel is a disc-shaped component mounted at the rear end of the engine crankshaft, typically made of cast iron or steel, and has a relatively large moment of inertia. It stores and releases energy, ensuring smooth engine operation, assisting in starting, overcoming short-term overload, and serving as the mounting base for the clutch. Using surface performance testing equipment, defects such as cracks and sand holes on the flywheel surface can be detected, along with indicators such as hardness and roughness, ensuring engine performance and safety, stable power transmission, and extending the service life of the flywheel and related components.
[0003] Currently, engine flywheel inspection mainly relies on manual operation. Before inspection, workers use a single clamp to fix the engine flywheel in place, and then carry out the inspection work. Since the flywheel needs to be frequently rotated to change the angle during inspection, the existing clamps have a fixed installation angle. Each time the angle is changed, the flywheel must be disassembled and readjusted. The whole process is not only labor-intensive and time-consuming, but also greatly reduces the efficiency of the inspection work. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an engine flywheel surface performance testing device, which aims to improve the current method of using a fixed-angle clamp to fix the flywheel during engine flywheel testing. This method results in the need to disassemble and reassemble the flywheel when changing the testing angle, which is both labor-intensive and time-consuming.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an engine flywheel surface performance testing device, comprising a fixed plate, wherein a left-right symmetrical arc-shaped sliding groove plate is fixedly connected to the upper surface of the fixed plate, a fixed rod is fixedly connected to one side of the outer wall of the fixed plate, a limit wheel is slidably connected inside the arc-shaped sliding groove plate, an installation plate is fixedly connected to one side of the outer wall of the limit wheel, and a clamping assembly is installed on the upper surface of the installation plate;
[0006] The clamping assembly includes a first rotating rod, the lower surface of which is fixedly connected to the upper surface of the mounting plate. A rotating plate is rotatably connected inside the first rotating rod, and a second rotating rod is fixedly connected inside the rotating plate. An arc-shaped plate is rotatably connected to the outer wall of the second rotating rod, and multiple second fixed rods are fixedly connected inside the arc-shaped plate. An elastic band is provided on the outer wall of the second fixed rod. A third rotating rod is rotatably connected inside the rotating plate, and a threaded sleeve is fixedly connected inside the third rotating rod. A bidirectional lead screw is threaded inside the threaded sleeve. An adjustment assembly is installed on one side of the outer wall of the first fixed rod.
[0007] Furthermore, the adjustment assembly includes a hydraulic cylinder, one end of which is rotatably connected to one side of the outer wall of a fixed rod, and a hinge block is fixedly connected to the output end of the hydraulic cylinder, one side of which is rotatably connected to one side of the outer wall of a fixed plate.
[0008] Furthermore, a base plate is provided directly below the fixing plate, and a support leg is fixedly connected to the lower surface of the base plate.
[0009] Furthermore, a rotating shaft is rotatably connected inside the base plate, and a gear is fixedly connected to the outer wall of the rotating shaft.
[0010] Furthermore, a limit rod is fixedly connected to the inner wall of the base plate, and a rack plate is slidably connected to the outer wall of the limit rod.
[0011] Furthermore, a transmission screw is rotatably connected inside the base plate, and the outer wall of the transmission screw is threadedly connected to the inside of the rack plate.
[0012] Furthermore, the gear teeth are meshed with the rack teeth, and the upper end of the rotating shaft is fixedly connected to the lower surface of the fixed plate.
[0013] Furthermore, a limiting block is fixedly connected to the outer wall of the second fixing rod, and the outer wall of the limiting block is disposed through the inside of the elastic band.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by placing the flywheel between two elastic bands, and then rotating the bidirectional lead screw, the threaded sleeve is moved, thereby driving the rotating rod to rotate. Then, by rotating the rotating plate, the arc plate is clamped and fixed. Then, by the deformation force of the elastic band, the clamping pressure is reduced, thus reducing damage to the flywheel surface. Then, by using a hydraulic cylinder, the limiting wheel on one side of the mounting plate slides inside the arc-shaped slide groove, thereby facilitating the change of angle for detection and improving the practicality of the device.
[0016] 2. In this utility model, the rack plate is driven to slide on the outer wall of the limiting rod by rotating the transmission screw. At this time, the rack plate is connected to the gear through meshing, thereby achieving the effect of driving the fixed plate above the rotating shaft to rotate. Then, through the rotation of the fixed plate, the flywheel can be detected from multiple angles, thereby improving the practicality of the device. Attached Figure Description

[0027] Specifically, a base plate 18 is located directly below the fixed plate 1. A support leg 19 is fixedly connected to the lower surface of the base plate 18. The support leg 19 supports the entire device, ensuring its stability and reliability during use. A rotating shaft 20 is rotatably connected inside the base plate 18.

The meshing of the gear 21 with the rack plate 23 allows the rotation of the rotating shaft 20 to be effectively converted into the rotation of the rack plate 23. The linear motion of the rack plate 23 is achieved by a limiting rod 22 fixedly connected to the inner wall of the base plate 18.

The fixed shaft provides stable support, ensuring the reliability and accuracy of the rotating system. The outer wall of the fixed rod 10 is fixedly connected to the limit block 11. The outer wall of the limit block 11 is inserted through the elastic band 12. The limit block 11, through its cooperation with the elastic band 12, provides a certain elastic adjustment function, effectively preventing the device from deviating from the predetermined position due to system vibration or misoperation. The elasticity of the elastic band 12 provides adjustment space for the limit block 11, helping to reduce instability caused by mechanical impact.
[0028] Working principle: When using this testing device to test the engine flywheel, the engine flywheel is first placed between two elastic bands 12. By rotating the double-acting screw 15, the threaded sleeve 14 drives the rotating plate 6 to rotate on the inner wall of the rotating rod 7. At this time, the rotation of the rotating plate 6 drives the arc plate 9 to move closer to the engine flywheel. Then, the movement of the arc plate 9 drives the elastic band 12 on the outer wall of the fixed rod 10 to clamp the engine flywheel. At the same time, the elastic band 12 reduces the clamping pressure, and the limiting block 1... 1. To prevent the elastic band 12 from slipping, the hydraulic cylinder 16 drives the limiting wheel 4 on one side of the mounting plate 5 to slide within the arc-shaped slide plate 2, thereby achieving the effect of easy angle adjustment for detection. At the same time, by rotating the transmission screw 24, the rack plate 23 is driven to slide on the outer wall of the limiting rod 22, thereby driving the rack plate 23 to mesh and rotate with the gear 21. Then, through the movement of the gear 21, the fixed plate 1 above the rotating shaft 20 is driven to adjust and rotate for multi-angle detection of the engine flywheel.
