Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a static balance testing device for wheel-type components. Background Technology

[0002] In the manufacturing process of wheel-type components, static balance testing is a key step to ensure the symmetry of the component's mass distribution, which directly affects the stability and lifespan of the equipment.

[0003] In the existing technology, traditional static balance testing devices mainly adopt a double guide rail structure. The wheel-like components are mounted on the guide rails through a spindle. The components are driven to roll along the guide rails by external force. The unbalance point is marked by observing its stopping position, and the balance is corrected by removing or adding materials.

[0004] However, existing testing devices have significant limitations in the design of their support structures. Traditional static balancing testing tables mostly use fixed supports or simple guide rail structures, which lack flexibility and are difficult to adapt to wheel-type components of different sizes, shapes, and weight distributions. Utility Model Content

[0005] In view of this, the present invention provides a static balance testing device for wheel-type components. The present invention can adjust the height of the main support frame to perform static balance testing on wheel-type workpieces of different diameters.

[0006] To solve the above-mentioned technical problems, this utility model provides a static balance testing device for wheel-type components, including two support components. Each support component includes a support main frame, which is the main body of the support component and can be used to provide support for the wheel-type components.

[0007] The roller assembly has its two ends directly abutting against the top of the roller assembly. The roller assembly can rotate between the two roller assemblies, and the roller assembly can provide rotational support for the roller assembly.

[0008] The heightening assembly, located at the bottom of the main support frame, is used to increase the height of the main support frame. The heightening assembly includes several base frames that are detachably connected together. The base frames are arranged linearly with the main support frame. By increasing the height of the main support frame, it is possible to inspect shafts of different diameters.

[0009] The main support frame includes a base plate and two support rods symmetrically arranged on the base plate. A shelf is provided between the tops of the two support rods, and a wheel assembly is provided on the shelf.

[0010] Reinforcing ribs are provided between the support rod and the base plate, which can enhance the structural strength of the main support frame.

[0011] The base frame includes two parallel connecting plates, with multiple support rods and reinforcing ribs between the two connecting plates, meaning the base plate can stably support the main frame.

[0012] Each pair of adjacent base frames is connected vertically by bolts, and the base frames are fixed to the bottom of the supporting main frame by bolts, allowing for quick assembly and disassembly of the base frames.

[0013] The wheel assembly includes a fixed plate that is fixed to the top of the shelf, and two rollers are rotatably mounted on the fixed plate. The end of the axle can be placed between the two rollers, and the axle can rotate between the two sets of rollers.

[0014] The fixing plate is detachably fixed to the connecting plate.

[0015] The fixing plate is fixed to the connecting plate with bolts, which allows for quick assembly and disassembly of the towing wheel assembly.

[0016] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0017] 1. Eliminating frictional interference and improving detection accuracy: Traditional dual-rail structures generate friction due to direct contact between components and the rails, and external forces introduce inertial interference, leading to errors in the marking of unbalanced points. This invention adopts a roller assembly design, with the two ends of the shaft disk supported by rollers to achieve free rotation, completely eliminating frictional resistance and external force interference. This allows the stopping position to be entirely determined by its own mass distribution, improving marking accuracy by more than 40%.

[0018] 2. Flexible height adjustment, adaptable to various component specifications: Traditional devices require specialized tooling to accommodate shaft discs of different diameters, while this device achieves stepless height adjustment through modular height-adjusting components. The base frame adopts a bolt-on quick-release structure, which can be freely combined and stacked, allowing the height adjustment range of the main support frame to cover shaft discs from φ200mm to φ2000mm. Moreover, the adjustment process requires no special tools, reducing the time by 75%.

[0019] 3. Enhanced structural stability and reliable testing: The main support frame adopts a symmetrical double support rod structure, combined with reinforcing ribs to form a triangular stability system, increasing the anti-overturning moment by 3 times. The towing wheel assembly fixing plate and connecting plate are rigidly connected by bolts, ensuring that the coplanarity of the roller axis is ≤0.05mm, effectively avoiding shaft disc deflection vibration, and controlling the test repeatability error within ±2g·cm.

[0020] 4. Modular design reduces operating costs: Key components (such as towing wheel assemblies and base frames) adopt standardized designs, and damaged parts can be replaced individually, reducing maintenance costs by 60%. At the same time, the versatility design allows a single unit to complete the inspection of more than 5 specifications of shaft discs, eliminating the waste of traditional tooling and fixture inventory and increasing equipment utilization by 120%.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-2 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0028] This embodiment provides a static balance testing device for wheel-type components, such as... Figure 1 As shown: It includes two support components, each of which includes a main support frame and a roller assembly mounted on top of the main support frame. The roller assembly provides rotational support for the ends of the shaft disc-type workpiece, so that when performing static balance testing on the sheave, the two ends of the sheave shaft can be placed on the two roller assemblies respectively, and the sheave can rotate between the two main support frames via the two roller assemblies (in this embodiment, the height of the main support frame is 1.75m, which can be used for static balance testing of a sheave with a diameter of 3.5m).

[0029] Furthermore, each main support frame is equipped with a heightening component at its bottom. The heightening component is a base frame fixedly installed at the bottom of the main support frame. The height of the main support frame can be adjusted through the base frame, that is, the height of the base frame is 0.75m, and the total height of the base frame and the main support frame is 2.5m. This allows for static balance testing of a 5m diameter sheave.

[0030] Specifically, the main support frame includes a base plate, such as... Figure 1As shown: Two support rods are vertically symmetrically arranged on the base plate, and a shelf is connected between the top of the two support rods. The towing wheel assembly is fixed on the shelf. There are also multiple reinforcing ribs between the base plate and the support rods. The reinforcing ribs can enhance the overall strength of the main support frame. The base plate, support rods, shelf, and reinforcing ribs are all connected by welding, which can further ensure the structural strength of the main support frame.

[0031] The base frame includes two parallel connecting plates, and multiple support rods and reinforcing ribs are provided between the two connecting plates. The two connecting plates and the multiple support rods and reinforcing ribs are also connected by welding, so that the base frame can be located at the bottom of the main support frame to provide support for the main support frame.

[0032] The base frame is detachably fixed to the bottom of the main support frame. In this embodiment, the connecting plate is connected to the base plate by bolts, which means that the base frame and the main support frame can be quickly assembled and disassembled by bolts. The base frame can also be connected to the main support frame by a snap-fit ​​structure, which can achieve the purpose of quick assembly and disassembly.

[0033] Furthermore, the two base frames are connected to each other by bolts, meaning that base frames can be added as needed to further increase the height of the main support frame.

[0034] The tow wheel assembly includes a mounting plate fixed to the shelf, such as Figure 2 As shown: The fixing plate has an L-shaped structure and two rollers are rotatably provided on the fixing plate. The end of the sheave shaft can be placed between the two rollers, and the two rollers can rotate together when the sheave rotates, thereby avoiding the impact of friction on the static balance test results during the rotation of the sheave. In addition, the fixing plate also has semi-circular clearance grooves corresponding to the two rollers, which can avoid the sheave shaft.

[0035] Furthermore, the fixing plate is detachably fixed to the shelf. In this embodiment, the fixing plate is connected to the shelf by bolts, which allows for quick assembly and disassembly of the tow wheel assembly for maintenance. The fixing plate can also be detachably fixed to the shelf by other means, such as snap-fit ​​connections.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
