Description

Technical Field

[0001] This utility model belongs to the technical field of wheel rim testing equipment, specifically relating to a high-precision wheel rim rolling testing device. Background Technology

[0002] As a core load-bearing component of the driving system of automobiles and light commercial vehicles, wheel rims directly bear the weight of the vehicle body, transmit driving and braking forces, and withstand complex dynamic loads such as road bumps and steering impacts. Their performance parameters, such as dimensional accuracy, structural strength, and fatigue life, not only determine the stability and handling of the vehicle, but also directly relate to the life safety of the driver and passengers. Therefore, in the production quality inspection, research and development improvement, and failure analysis of wheel rims, it is necessary to comprehensively verify their key performance through high-precision testing equipment. The universal testing machine is the core equipment to achieve this requirement.

[0003] In practical applications, existing rim rolling test equipment generally suffers from poor adaptability of fixture components, making it incompatible with rims of different specifications. On the other hand, the coordination between the upper and lower fixtures is poor, resulting in insufficient rim fixing accuracy and stability. At the same time, test safety is difficult to guarantee, as there is a lack of effective protective measures. During the test, there is a high risk of rims or related components splashing, posing a threat to the personal safety of operators.

[0004] Therefore, this application proposes a high-precision wheel rim rolling test device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision wheel rim rolling test device, comprising a base, a control console and symmetrically distributed frames fixedly connected to the top of the base, a mounting base plate fixedly connected between the two frames, and a hydraulic cylinder fixedly connected to the top of the frame, and an upper clamping assembly provided, wherein the telescopic end of the hydraulic cylinder is fixedly connected to the upper clamping assembly for fixing the wheel rim, and a lower clamping assembly that cooperates with and is fixedly fixed to the top of the mounting base plate, and a protective assembly for enhancing test safety fixedly connected to the front of the two frames; The upper clamping assembly includes a connecting column fixedly connected to the telescopic end of the hydraulic cylinder. A grooved base is fixedly connected to the bottom of the connecting column. An arc-shaped support block is placed inside the grooved base. A limiting hole is opened at the front of the arc-shaped support block. Through holes are opened at the front and rear of the grooved base. An insertion and fixing component is inserted into the through holes. The end of the insertion and fixing component passes through the limiting hole of the arc-shaped support block and extends to the rear of the grooved base. A winding rod is fixedly connected to each of the four outer corners of the grooved base. A tightening strap for assisting in fixing the rim is wound on the winding rod.

[0007] Using the above scheme, the upper clamping assembly is used to fix the upper part of the wheel rim, and the lower clamping assembly is used to fix the lower part of the wheel rim. The two work together to achieve a better fixing effect. The protective assembly protects the operator's safety during the test and prevents injury caused by the rim or components flying off during the test.

The insertion rod is inserted into the slotted base and the hole of the arc-shaped support block. The insertion rod is fastened by the cooperation of the connecting screw and the connecting nut. A protrusion is provided on the outer surface of the insertion rod. This protrusion can facilitate positioning and enhance friction. The shape of the protrusion is adapted to the limiting hole of the arc-shaped support block to prevent it from loosening during the test and ensure the stability of the position of the arc-shaped support block.

[0013] Using the above scheme, the protective components are used to form a protective barrier during the test. The sliding cylinder and sliding rod are slidably connected, which allows the operator to adjust the position of the fixed frame as needed. The tempered glass ensures protection without affecting the observation of the test process. The connection between the fixing bolts and the internal thread groove of the sliding rod realizes the fastening of the fixed frame, ensuring the stability of the protective components during the test, while also facilitating disassembly.

[0014] In a preferred embodiment, vertical plates are fixedly connected between the slide cylinders on the same side.

[0015] Using the above scheme, the upright plate enhances the stability of the slide structure and provides lateral protection. The upright plate works in conjunction with the front protection to reduce blind spots.

[0016] In a preferred embodiment, the lower clamp assembly includes a grooved base two fixedly connected to the top of the mounting base plate.

[0017] Using the above scheme, the lower clamp assembly is used to fix the lower part of the wheel rim, and the grooved base provides an installation base for the push rod, clamp plate, etc. The push rod can drive the clamp plate to move back and forth to adjust the fit between the clamp plate and the wheel rim. The cooperation of the limit screw and the limit nut is used to fix the position of the clamp plate and prevent it from moving during the test, so as to ensure the fixing effect of the lower part of the wheel rim.

[0018] In a preferred embodiment, the grooved base two has a limiting hole at its rear for use with a limiting screw, and the end of the limiting screw passes through the limiting hole through the grooved base two and extends to the rear of the grooved base two.

By tightening the limiting nut, the clamping plate can be stably fixed on the grooved base two, ensuring the reliability of the lower clamping assembly's fixation to the wheel rim. The clamping plate and the limiting screw block the upper part, achieving a double fixing effect.

[0020] Compared with the prior art, the beneficial effects of this utility model are: The upper and lower clamping assemblies work together to achieve high-precision and high-stability fixation of the rim. The upper clamping assembly fits against the upper part of the inner ring of the rim with an arc-shaped support block, and the insertion component and the tightening strap ensure its stable position. The lower clamping assembly firmly fixes the lower part of the rim with the double structure of clamping plate and limit screw support. The two are in the same vertical plane, so that the rim is subjected to uniform force. It can adapt to rims with different inner ring arcs by changing the arc-shaped support blocks with different arcs, and can also achieve multi-dimensional force support by using the preset hole positions of the rim, which greatly improves the fixation accuracy and deformation resistance of the rim during the test.

[0021] The protective components can significantly improve test safety. The sliding cooperation between the slide cylinder and the slide rod enables convenient installation and disassembly of the fixed frame. The tempered glass ensures safety without obstructing test observation. The vertical plate between the slide cylinders on the same side and the front fixed frame form a three-dimensional protection, reducing blind spots. This structure not only allows operators to quickly adjust the protection range according to test needs, but also effectively blocks the splashing of rims or parts during the test, while facilitating daily maintenance and repair of the equipment.

The cooperation of the limiting screw 73 and the limiting nut 72 is used to fix the position of the clamping plate 74, preventing it from moving during the test and ensuring the fixing effect of the lower part of the wheel rim.

[0030] The grooved base 71 has a limiting hole at the rear for use with the limiting screw 73.

Therefore, some of the technology is existing in this device, and the working principle is well known, so it will not be described in detail here. During the test, the test situation can be observed through the tempered glass 65. The arc-shaped support block 54 contacts the structure above the inner ring of the wheel rim and plays a supporting role. The arc-shaped support block 54 with different curvature can be replaced according to the curvature of the inner ring of the wheel rim. If the inner ring of the wheel rim to be tested cannot be placed in the arc-shaped support block 54, the insertion component 53 can be directly inserted through the preset hole of the inner ring of the wheel rim to the back of the grooved base 52. Then the connecting screw 533 is threaded to the nut 534 for fixation. Thus, the horizontal insertion rod 532 directly receives force support, driving the wheel rim to move upward.
