Description

Technical Field

[0001] The invention belongs to the technical field of disc hub detection, in particular to a clutch disc hub detection device. Background Art

[0002] The clutch is located in the flywheel housing between the car engine and the gearbox. It is an assembly directly connected to the engine in the car transmission system. Usually, the clutch is installed together with the flywheel assembly of the engine crankshaft. It is a component that cuts off and transmits power between the engine and the car. The clutch hub is an important component in the clutch. It mainly bears the clutch load and transmits the torque of the driven plate assembly. In order to ensure the service life and safety of the clutch, it is necessary to ensure the rationality of the design of the clutch hub and the safe working state, which will directly affect the service life and safety of the clutch. Make its working state stable and reliable after installation, without the hidden dangers of falling off and breaking.

[0003] In the current existing technology, the existing clutch hub needs to be manually sampled and tested after it is manufactured, and when the clutch hub is manually carried to the testing platform, the heavier clutch hub cannot be put together at once when it is placed, and collision friction will occur in this process. In addition, the upper and lower sides of the clutch hub need to be tested, and scratches are easily caused during the flipping process, resulting in the clutch hub passing the test but affecting the overall appearance due to scratches on the surface, which not only requires rework at a later stage, but also increases the workload.

[0004] To this end, the present invention provides a clutch hub detection device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The outer surface of the slider is provided with a positioning and rotating unit, and the positioning and rotating unit includes a limiting rotating rod fixedly connected to the outer surface of the slider, and the other end of the limiting rotating rod is movably sleeved with a overlapping platform. When the processing detector has completed the all-round detection of the top surface of the clutch hub, the overlapping platform is pulled back and the limiting rotating rod is used to flip the overlapping platform, and the other side surface of the clutch hub is moved to the bottom surface of the processing detector for detection, so that the clutch hub is in a suspended state during the process of moving back and forth and flipping, and the external supporting and limiting devices only contact with the surface of the overlapping platform, reducing the contact between the clutch hub and external equipment and avoiding the effect of excessive scratches on the surface of the clutch hub. A wear-resistant and scratch-proof cloth is provided on the outer surface of the overlapping platform, and a closing cover is swingably connected to the edge position of one side of the top of the overlapping platform. The swinging closing cover overlaps one side surface on the top surface of the clutch hub, and the upper and lower surfaces of the clutch hub are swung by the closing cover and the overlapping platform. The bottom surface and the surrounding edge positions are wrapped and limited, and the bottom of the slider is supported by a hydraulic oil rod, so as to support the bottom surface of the lap platform, so as to avoid that the heavier clutch hub is overlapped on the surface of the lap platform and cannot maintain internal balance in the first time, thereby causing the lap platform to tilt. The lap platform and the inner wall surface of the closing cover are provided with overlapping grooves, and the outer surface of the clutch hub is effectively sleeved together with the overlapping grooves, and the width of the overlapping grooves can effectively overlap some clutch hubs of different sizes, so as to achieve the effect of effectively placing and overlapping clutch hubs of different sizes. The bottom surface of the lap platform is fixedly connected with a sleeve shell at the edge position of one side, and the lap platform is pushed to the inner side of the detection platform, and the sleeve shell on the bottom surface of the lap platform is docked with the docking limit column to limit the position of the lap platform. At the same time, the hydraulic oil rod is cooperated to rise and squeeze on the bottom surface of the lap platform to support and limit the four corners of the bottom of the lap platform.

[0008] The inner wall surface of the bottom of the detection table is symmetrically fixed with hydraulic oil rods arranged on the bottom edge position of the overlapping table at both side edge positions; the inner wall surface of one side of the detection table is fixedly connected with a docking limit column movably sleeved on the inner wall surface of the sleeve shell at the middle position; the top outer surface of the detection table is provided with a processing detector at one side edge position of the docking limit column.

[0012] Preferably, a pushing plate movably sleeved on the inner wall of the limiting groove is fixedly connected to the top of the elastic wire, which cooperates with the elastic wire to push the fitting panel in the opposite vertical direction and push some thinner clutch hubs so that the clutch hub is in a central suspended state between the overlapping platform and the closing cover, and the elastic gap of the elastic wire can effectively compress and control the clutch hubs of different thicknesses. A fitting panel movably overlapped on the top surface of the sleeve is fixedly connected to the top surface of the pushing plate. When the overlapping platform and the closing cover are closed, the clutch hub will squeeze the fitting panel, so that the pushing plate on the bottom surface of the fitting panel slides vertically down on the inner wall of the limiting groove and thus compresses the elastic wire. A non-slip soft strip movably sleeved on the outer surface of the clutch hub is fixedly connected on the top surface of the fitting panel.
