[0001] This utility model relates to the technical field of wheel hub processing, and in particular to a wheel hub hole position detection fixture. Background Technology
[0002] In the field of mechanical manufacturing, wheel hubs are key components, and the machining accuracy of their bores directly affects the assembly quality and performance of the entire machine. Pump wheel hubs, in particular, typically have high positional accuracy requirements and strict tolerance ranges.
[0003] With the development of automation technology, some semi-automatic or fully automatic inspection equipment has been gradually applied. For example, a vision recognition system is used to acquire and compare images of hole positions, or a fixed inspection probe is used in conjunction with a displacement sensor for measurement. However, these methods often have certain limitations: vision systems are easily affected by ambient light and surface reflection, resulting in unstable accuracy; and fixed probe-type inspection devices usually lack flexible positioning adjustment capabilities, making it difficult to adapt to the inspection needs of wheel hubs of different specifications.

[0016] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the appended spirit and connotation.
[0017] The following description, in conjunction with the accompanying drawings, describes a hub hole detection fixture according to an embodiment of the present invention.
[0018] like Figure 1-5 As shown in the figure, a hub hole position detection fixture according to an embodiment of the present invention includes a detection platform 10, a support and limiting component 20 and a detection component 30.
[0019] The support and limiting component 20 is rotatably mounted on the detection platform 10. The support and limiting component 20 includes a rotating disk 201 and a limiting mechanism 202.
[0020] The rotating disk 201 is rotatably mounted on the detection platform 10, and there are multiple sets of limiting mechanisms 202, which are rotatably mounted on the rotating disk 201 respectively. The detection component 30 is mounted on the detection platform 10.
[0021] It should be noted that the detection platform 10 described in this embodiment is placed on a horizontal surface. A stepper motor is provided inside the detection platform 10. The output end of the stepper motor is connected to the support and limiting component 20 through a reducer. The top horizontal surface of the support and limiting component 20 and the end face of the detection platform 10 used to support the support and limiting component 20 are located on the same horizontal end face to ensure overall flatness.
[0022] Furthermore, the rotating disk 201 is mounted on the detection platform 10 via bearings, which ensure the stability of the rotating disk 201 during rotation. The limiting mechanism 202 is arranged in a ring array on the rotating disk 201. The pump hub to be tested is placed in the limiting mechanism 202, which then drives the hub to rotate to the detection position, and the holes on the hub are tested one by one.
[0023] In one embodiment of this utility model, such as Figure 2 As shown, the limiting mechanism 202 includes an outer ring 2021, a pressing component 2022, and a laser reactor 2023.
[0024] The outer ring 2021 is rotatably mounted on the rotating disk 201, the pressing component 2022 is mounted inside the outer ring 2021, and the laser reactor 2023 is mounted at the center of the bottom of the inner side of the outer ring 2021.
[0025] It should be noted that the outer ring 2021 is mounted inside the rotating disk 201 via bearings. A motor for controlling the rotation of each limit mechanism 202 is located inside the rotating disk 201. Both the motor controlling the rotation of the limit mechanism 202 and the motor controlling the rotation of the rotating disk 201 are controlled by a controller to adjust their rotation angle for each rotation. This ensures that each rotation brings the different holes on the hub directly below the detection assembly 30 for detection.
[0026] Furthermore, the pressing components 2022 are symmetrically arranged on both sides inside the outer ring 2021 to press and fix the incoming wheel hub, while the laser reactor 2023 works in conjunction with the center detection and positioning system on the detection assembly 30 to determine whether the wheel hub has rotated into position through laser alignment detection. The aforementioned center detection and positioning system is prior art and will not be described in detail here.
[0027] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the pressing component 2022 includes an inner sleeve 20221, a movable rod 20222, a limiting pressure plate 20223, and a buffer component 20224.
[0028] The inner sleeve 20221 is located inside the outer ring 2021, one end of the movable rod 20222 is movably located inside the inner sleeve 20221, the limiting pressure plate 20223 is located at the other end of the movable rod 20222, and the two ends of the buffer component 20224 are respectively connected to the inner sleeve 20221 and the movable rod 20222.
[0029] It should be noted that the movable rod 20222 extends and retracts within the inner sleeve 20221 to adjust its length. The buffer component 20224 is a buffer spring. The buffer component 20224 pushes the movable rod 20222 to move, causing the limiting pressure plate 20223 to fit against the hole of the wheel hub to be tested.
[0030] Furthermore, an inclined end face is provided on one side of the limiting pressure plate 20223, and a rounded corner is provided at the top of the inclined end face. The rounded corner and the inclined end face facilitate the placement and limiting of the wheel hub.
[0031] In one embodiment of this utility model, such as Figure 1 As shown, the detection component 30 includes a drive component 301 and a detection mechanism 302.
[0032] The drive component 301 is mounted on the detection platform 10, and the detection mechanism 302 is mounted on the output end of the drive component 301.
[0033] It should be noted that the drive component 301 is a hydraulic cylinder. The drive component 301 is operated by connecting to the control switch and the power supply, and the drive component 301 pushes the detection mechanism 302 to move up and down.
[0034] In one embodiment of this utility model, such as Figure 4 As shown, the testing mechanism 302 includes a positioning platform 3021, a base column 3022, a testing rod 3023, and a sensing and testing fixture 3024.
[0035] The positioning platform 3021 is located at the output end of the drive component 301, the bottom column 3022 is located on the positioning platform 3021, the detection rod 3023 is located on the bottom column 3022, and the sensing and detection fixture 3024 is located on the detection rod 3023.
[0036] It should be noted that the positioning platform 3021 and the output end of the drive component 301 are connected as a whole support platform. The bottom column 3022 is a hollow column, and the detection rod 3023 is inserted into the inner side of the bottom column 3022. The sensing detection fixture 3024 is set on the detection rod 3023. During the detection process, the bottom column 3022 moves into the hole to be detected, and the sensing detection fixture 3024 detects the hole.
[0037] In one embodiment of this utility model, such as Figure 5 As shown, the sensing and detection fixture 3024 includes a middle partition plate 30241, a pressure sensor 30242, a buffer component 30243, and a buffer pad 30244.
[0038] The intermediate partition 30241 is disposed inside the detection rod 3023, the pressure sensor 30242 is disposed on the intermediate partition 30241, the buffer pad 30244 is movably disposed on the detection rod 3023, one end of the buffer member 30243 is connected to the buffer pad 30244, and the other end of the buffer member 30243 is movably disposed inside the intermediate partition 30241.
[0039] It should be noted that, in this embodiment, the intermediate partition 30241 divides the inner side of the detection rod 3023 into two cavities. Pressure sensors 30242 are respectively disposed inside the cavities. The buffer 30243 includes a push rod with a spring sleeved on it. One end of the push rod slides in the intermediate partition 30241, and the other end of the push rod is connected to a buffer pad 30244. The buffer pad 30244 moves in the detection rod 3023 and detects and judges the detection hole. When the hole is unqualified, the buffer pad 30244 retracts to the inner side of the detection rod 3023 and abuts against the pressure sensor 30242, thereby determining that the hole to be detected is unqualified.
[0040] Furthermore, the distance from which the buffer pad 30244 extends out from the outer end face of the detection rod 3023 is set according to the diameter of the hole to be detected on the wheel hub. Under the condition of no external force interference, the outer surface of the buffer pad 30244 and the inner side of the hole to be detected are interference fit. During the detection process, the buffer pad 30244 is judged according to the required hole position accuracy, and the accuracy of its inward extension and retraction is controlled within 0.2mm to 0.5mm.
[0041] Specifically, the steps for inspecting the holes on the hub are as follows: First, the pump hubs to be inspected are placed sequentially within the limiting mechanism 202 on the rotating disk 201. The limiting mechanism 202 reinforces the hubs. When the hubs are installed inside the outer ring 2021, the limiting pressure plate 20223 in the pressing component 2022 pushes the movable rod 20222 to move through the buffer component 20224, causing the limiting pressure plate 20223 to abut against the surface of the hub to be inspected, thus fixing the hubs in place. Subsequently, the rotating disk 201 rotates, causing each hub to change position, and each outer ring 2021 rotates independently during the inspection process, thereby inspecting multiple holes on the hubs separately.
[0042] During testing, the drive unit 301 pushes the testing mechanism 302 to move up and down. The testing rod 3023 in the testing mechanism 302 moves down to test the hole position. The buffer pad 30244 moves in the testing rod 3023 and tests and judges the test hole. When the hole is unqualified, the buffer pad 30244 retracts to the inside of the testing rod 3023 and abuts against the pressure sensor 30242, thus judging that the hole to be tested is unqualified. Conversely, it is judged to be qualified because it does not contact the pressure sensor 30242.
[0043] In summary, the wheel hub hole position detection fixture of this utility model uses a multi-group limiting installation method to detect the wheel hub at one time, which is suitable for detecting wheel hubs of different specifications, ensuring detection accuracy and improving detection efficiency.
[0044] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
