Description

Technical Field

[0001] The invention relates to the technical field of flywheel housing processing and detection, in particular to a detection device for flywheel housing processing and production. Background Art

[0002] The flywheel housing is an important part of the engine. It mainly supports and protects the flywheel. The flywheel is a disk with a large moment of inertia. During the operation of the engine, the flywheel stores energy and makes the engine run more smoothly. The flywheel housing surrounds the flywheel to prevent damage to the flywheel by external objects, and also avoids safety hazards caused by the flywheel rotating at high speed.

[0003] The existing flywheel housing needs to be tested for hardness during the production process. The appropriate hardness can ensure the wear resistance and deformation resistance of the flywheel housing. If the flywheel housing is made of cast iron material and its hardness does not meet the standard, it may suffer excessive wear during contact with other parts.

[0004] When performing hardness testing on an existing flywheel housing, the flywheel housing needs to be fixed first. In order to ensure that the flywheel housing is fixed more firmly, multiple cylinders are often used to fix it at multiple angles to avoid displacement of the flywheel housing during the testing process, which affects the accuracy of the hardness tester test data. However, the use of multiple cylinders for fixing not only takes up a lot of space, but also increases the cost of the device and electricity. In order to save costs, some factories use manual manual driving of multiple clamping components to fix the flywheel housing, but this method has a low efficiency in positioning and fixing the flywheel housing.

[0005] Based on this, a detection device for flywheel housing processing and production is now provided, which can eliminate the disadvantages of the existing devices. Summary of the invention

The output end of the motor 8 is fixedly connected to the first rotating shaft 25, and the top end of the first rotating shaft 25 is fixedly connected to the rotating disk 17.

[0038] The motor 8 is started, and the motor 8 drives the rotating disk 17 to rotate through the first rotating shaft 25.

[0044] When the flywheel housing has a tendency to move, the flywheel housing drives the friction plate 31 to slide, and the sliding of the friction plate 31 drives the inclined plate 33 to squeeze the first spring 34, so that the extrusion plate 32 is squeezed into the extrusion plate groove and contacts with the bottom of the flywheel housing, thereby increasing the pressure and friction with the bottom of the flywheel housing.

[0045] In one embodiment, the second clamping assembly 7 includes an L-shaped rack 12 and a gear ring 16, the gear ring 16 is fixedly connected to the peripheral side of the rotating disk 17, two L-shaped racks 12 are slidably connected to the upper surface of the support plate 10, two guide rails 11 are fixedly connected to the upper surface of the support plate 10, and a slider is provided on the side wall of the L-shaped rack 12. The slider on the side wall of the L-shaped rack 12 is slidably connected to the inner wall of the guide rail 11, and the two L-shaped racks 12 are meshed with the gear ring 16 together.

[0046] The rotating disk 17 rotates the gear ring 16, and the rotation of the gear ring 16 drives the L-shaped rack 12 to move.

[0050] S3: Start the motor 8, the motor 8 drives the rotating disk 17 to rotate through the first rotating shaft 25, and the rotation of the rotating disk 17 drives the four moving columns 18 to move away from each other. At this time, the four moving columns 18 contact the inner ring of the flywheel housing to be positioned and fixed;

[0052] S5: At the same time, the rotating disk 17 rotates the gear ring 16, and the rotation of the gear ring 16 drives the L-shaped rack 12 to move. The movement of the L-shaped rack 12 drives the two first contact plates 15 to move toward each other, fixing the two side walls outside the flywheel housing, further improving the fixing and clamping effect.

[0053] S5: When the flywheel housing has a tendency to move, the flywheel housing drives the friction plate 31 to slide, and the sliding of the friction plate 31 drives the inclined plate 33 to squeeze the first spring 34, squeezing the extrusion plate 32 into the extrusion plate groove to contact the bottom of the flywheel housing, thereby increasing the pressure and friction with the bottom of the flywheel housing, further preventing the flywheel housing from moving during the test and affecting the hardness tester detection data.
