Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel hub manufacturing technology, and in particular to a wheel spoke deformation detection device. Background Technology

[0002] Aluminum alloy wheels are a core component for safe driving. Their dimensional accuracy and degree of deformation directly affect driving safety. Therefore, the industry has extremely strict requirements for the frequency and items of wheel inspection. During the casting, forging, and heat treatment processes of wheel hubs, the blanks are prone to irregular deformation due to factors such as thermal expansion and contraction of materials, internal stress release, and fluctuations in forming processes. If this deformation is not identified in time before machining, and the product is scrapped due to deformation after machining, it will not only waste raw materials but also cause a series of ineffective expenditures such as equipment wear and tear, labor costs, and auxiliary material consumption in the machining process, significantly increasing production costs.

[0003] In existing technologies, two main methods are used to detect wheel hub spoke deformation: one is blank sawing inspection, which judges the deformation by comparing the profile after sawing the blank, but this method is destructive and will directly lead to the scrapping of the blank, and the profile comparison accuracy is low; the other is three-coordinate scanning inspection, which obtains the blank spoke profile by scanning and compares it with the theoretical model. Although the accuracy is high, the inspection is time-consuming and cannot meet the needs of multiple and rapid inspections of the same batch of products, making it difficult to grasp the deformation pattern of the same batch of products.

[0004] Based on the aforementioned shortcomings of existing technologies, there is an urgent need to design a convenient, efficient, and non-destructive wheel spoke deformation detection device to improve the frequency and timeliness of product testing and reduce production costs. Utility Model Content

[0005] This utility model aims to solve the technical problems in the existing wheel hub spoke deformation detection, such as sawing detection which wastes blanks and has low accuracy, and three-coordinate scanning detection which is time-consuming and cannot be adapted to multiple inspections. At the same time, it aims to improve inspection efficiency, reduce the labor intensity of operators, and adapt to the inspection of multiple types of products.

[0006] The technical solution adopted in this utility model is as follows: A spoke deformation detection device includes a base, on which a support structure for stably supporting and positioning a wheel hub to be tested is provided, and a detection component for detecting spoke deformation of the wheel hub to be tested. The detection component includes a column vertically connected to the base, a horizontal slide rod connected to the upper end of the column along the diameter direction of the wheel hub to be tested, a horizontal sliding sleeve sleeved on the horizontal slide rod, a vertical guide sleeve fixedly connected to the horizontal sliding sleeve, and a vertical slide rod slidably connected inside the vertical guide sleeve; a drawing board parallel to the horizontal slide rod is provided on the column; a drawing pen is provided at the top of the vertical slide rod corresponding to the drawing board, and a roller that abuts against the wheel hub to be tested is rotatably connected to the bottom end of the vertical slide rod.

[0007] Preferably, the drawing board surface is pre-attached with a standard wheel spoke profile drawing to facilitate comparison with the actual drawn wheel spoke profile.

[0008] Preferably, a spring is provided between the vertical slide rod and the vertical guide sleeve. The lower end of the spring abuts against the limiting platform of the vertical slide rod, and the upper end abuts against the lower edge of the vertical guide sleeve, providing the vertical slide rod with preload force against the receiving hub.

[0009] Preferably, the paintbrush is connected to the top of the vertical slide bar via an elastic connector, which can adaptively adjust the contact pressure between the paintbrush and the drawing board.

[0010] Preferably, the support structure includes a support base that is fixedly connected to the base, and a bearing plate is provided on the support base. The upper end face of the bearing plate is designed as a flat and fitting surface corresponding to the flange end face of the wheel hub to be tested. A positioning post is provided at the center of the bearing plate corresponding to the center hole of the wheel hub to be tested, and the positioning post is inserted into the center hole.

[0011] Preferably, the bearing plate and the support base are detachably connected for easy and quick replacement.

[0012] Preferably, one end of the horizontal slide bar and the drawing board are respectively connected to the column, and the other end is respectively connected to the vertical extension rod of the positioning column, forming a double support and fixing structure. The beneficial effects of this utility model are as follows: This invention abandons the traditional destructive sawing inspection method, completing spoke deformation detection without damaging the blank, thus avoiding the waste of qualified blanks from the source. Simultaneously, through the spring pre-tightening of the roller and spokes, the elastic connection of the drawing pen, and the double support and fixation of the horizontal sliding rod, the accuracy of the profile marking is far superior to manual comparison by sawing, effectively compensating for the lack of precision. Compared to the time-consuming three-coordinate scanning, this device only requires 2-3 minutes for a single inspection, requiring no complex calibration or data processing, and can be operated by a single person. It can efficiently meet the needs of multiple sampling inspections of the same batch of products, acquiring spoke deformation data in real time and accurately grasping the deformation patterns of the same batch of products. Furthermore, through the quick-release replacement design of the bearing plate, it can be adapted to the inspection of different specifications of wheel hubs, eliminating the need to purchase separate equipment and significantly reducing the equipment investment cost for inspecting multiple specifications of products. In addition, by using flange end face bonding and positioning post insertion positioning, it ensures that the benchmark is consistent for each inspection, further improving the reliability of the inspection and ultimately reducing the waste of ineffective machining costs.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figure 1 As shown, a spoke deformation detection device includes a base 10, on which a support structure is provided for stably supporting and positioning a wheel hub to be tested; a detection component is provided on the base 10 for detecting spoke deformation of the wheel hub to be tested; the detection component includes a column 31 vertically connected to the base 10, a horizontal slide rod 32 arranged along the diameter direction of the wheel hub to be tested connected to the upper end of the column 31, a horizontal sliding sleeve 33 that can slide freely along the slide rod is sleeved on the horizontal slide rod 32, the horizontal sliding sleeve 33 is fixedly connected to a vertical guide sleeve 34, and a vertical slide rod 35 is slidably connected inside the vertical guide sleeve 34; a drawing board 36 parallel to the horizontal slide rod 32 is provided on the column 31 for marking the spoke profile; a drawing pen 37 is provided at the top of the vertical slide rod 35 corresponding to the drawing board 36, and a roller 38 that abuts against the wheel hub to be tested is rotatably connected to the bottom end of the vertical slide rod 35.

[0018] During inspection, the wheel hub to be inspected is placed on the support structure, with the bottom roller 38 of the vertical slide bar 35 abutting against the spoke surface, and the tip of the pen 37 contacting the drawing board 36. At this time, the vertical slide bar 35 is pushed along the diameter direction of the wheel hub to be inspected, and the vertical slide bar 35 moves horizontally under the guidance of the horizontal slide bar 32. During this process, the roller 38 at the bottom of the vertical slide bar 35 rolls adaptively along the spoke surface, simultaneously driving the vertical slide bar 35 to rise and fall vertically under the guidance of the vertical guide sleeve 34, thus allowing the pen 37 at the top of the vertical slide bar 35 to trace the spoke profile of the wheel hub to be inspected on the drawing board 36. Then, the traced spoke profile is compared with the standard profile to quickly determine the amount of wheel hub deformation. If the deformation exceeds the standard, it is promptly reworked or scrapped to avoid waste of processing costs in the machining process. This embodiment achieves synchronous linkage of the pen 37 along the radial and axial directions of the wheel spokes through the cooperation of the horizontal slide bar 32 and the vertical guide sleeve 34, ensuring the real-time performance and accuracy of the wheel spoke line drawing. The detection process does not require complex equipment calibration or data processing, can be operated by a single person, and the time for a single detection can be shortened to 2-3 minutes, greatly improving detection efficiency, while avoiding damage to the blank and reducing production costs.

[0019] Preferably, the surface of the drawing board 36 can be pre-attached with standard wheel spoke profile drawings for direct comparison with the actual drawn wheel spoke profiles, visually displaying the wheel hub deformation and improving detection efficiency.

[0020] Preferably, a spring 39 is provided between the vertical slide rod 35 and the vertical guide sleeve 34. The lower end of the spring 39 abuts against the limiting platform of the vertical slide rod 35, and the upper end abuts against the lower edge of the vertical guide sleeve 34, providing a preload force for the vertical slide rod 35 to abut against the receiving hub, ensuring that the roller 38 is always in close contact with the spoke surface, avoiding deviations in the profile marking caused by the contact gap, and ensuring the accuracy of the test data. At the same time, the pen 37 is connected to the top of the vertical slide rod 35 through an elastic connector (such as a miniature spring 39), which can adaptively adjust the contact pressure between the pen 37 and the drawing board 36. This can avoid the marking line breakage caused by insufficient pressure, and prevent the pen 37 from wearing or the drawing board 36 from being damaged by excessive pressure, ensuring clear and complete marking and providing a reliable basis for the determination of deformation.

[0021] Preferably, the support structure includes a support base 21 fixedly connected to the base 10, and a bearing plate 22 is provided on the support base 21. The upper end face of the bearing plate 22 is designed as a flat and fitting surface corresponding to the flange end face of the wheel hub to be inspected. During inspection, the flange end face of the wheel hub to be inspected is tightly fitted with the upper end face of the bearing plate 22 to ensure the levelness of the wheel hub to be inspected, avoid the offset of the spoke profile marking due to the tilt of the wheel hub, and improve the efficiency of inspection preparation. A positioning post 23 is provided at the center of the bearing plate 22 corresponding to the center hole of the wheel hub to be inspected. The positioning post 23 is inserted into the center hole for radial positioning of the wheel hub to be inspected. This can avoid the deviation of the profile marking position caused by radial misalignment of the wheel hub; at the same time, the positioning operation is simple, without the need for repeated manual adjustments, improving the repeatability and consistency of inspection of the same batch of products.

[0022] Preferably, the bearing plate 22 is detachably connected to the support base 21 to facilitate quick replacement of bearing plates 22 of different sizes, meet the testing needs of wheel hubs of different specifications (such as different center hole diameters and flange diameters), improve applicability, eliminate the need to design separate testing devices for wheel hubs of different specifications, and only need to replace the appropriate bearing plate 22 to complete the specification switching, greatly reduce the investment cost of testing equipment for multi-specification products, and improve equipment utilization.

[0023] Preferably, one end of the horizontal slide bar 32 and the drawing board 36 are respectively connected to the column 31, and the other end is respectively connected to the vertical extension rod 24 of the positioning column 23, forming a double support and fixing structure to ensure the stability of the horizontal slide bar 32 and the drawing board 36 and improve the accuracy of the profile drawing; at the same time, the positioning column 23, the horizontal slide bar 32, and the drawing board 36 form a linkage positioning reference to ensure that the radial reference of the wheel spoke profile drawing is always consistent with the center of the wheel hub, thereby improving the accuracy of deformation determination.

[0024] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
