Description

Technical Field

[0001] This utility model relates to the field of wheel hub inspection technology, and in particular to a novel movable wheel hub roundness measuring device. Background Technology

[0002] In the wheel manufacturing industry, roundness is one of the key indicators for measuring wheel quality, which directly affects the performance and safety of the wheel after assembly. Therefore, the detection of wheel roundness is an indispensable part of the production process.

[0003] Under the current production model, due to the lack of flexible and mobile real-time inspection equipment, companies must manually collect each finished wheel hub piece by piece. Once a certain quantity is accumulated, it is stacked into a pallet and then transported to a fixed inspection point for roundness testing. This process involves a significant time interval between wheel hub production completion and the start of inspection, during which the production line continues to produce wheels of the same batch. If a batch of wheels has roundness issues due to deviations in production equipment parameters or fluctuations in raw material characteristics, the defects cannot be detected in time, leading to a continuous output of substandard products and a large batch of defective scrap. These defective scraps not only result in direct waste of raw materials but also require additional manpower for sorting, cleaning, and processing, further increasing the burden on the production process and reducing overall resource utilization.

[0004] In addition, the traditional centralized testing model also faces the problem of long waiting times for testing. Typically, the number of fixed testing points within a company is limited, while wheel pallets produced by multiple production lines need to be sent to the same testing point for testing. Especially during peak production periods, the number of wheel pallets waiting to be tested increases significantly, easily leading to long waiting times for testing. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that relies on manually assembling a pallet for inspection, which generates a large number of abnormal and defective products during the inspection process, and requires queuing for inspection, resulting in a waste of human resources and material costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel movable wheel hub roundness measuring device, comprising: a mounting frame; a movable base, mounted on the upper surface of the mounting frame, with a limiting guide groove formed at its upper end; two clamping plate assemblies, arranged opposite each other and slidably mounted in the limiting guide groove; and two detection components, mounted on the upper surface of the mounting frame and located on one side of the two clamping plate assemblies; wherein the two clamping plate assemblies can move closer to or further away from each other.

[0007] The technical effect of adopting the above-mentioned further solution is that, in use, the wheel hub can be fixed between the two clamping plate assemblies first, and the two clamping plate assemblies can move closer or further apart from each other in the limiting guide groove on the movable base to adapt to wheel hubs of different sizes and lengths. Then, the roundness of the wheel hub can be detected by using two detection components on one side of the two clamping plate assemblies.

[0008] Preferably, the clamping plate assembly includes: a mounting base plate, slidably mounted above the movable base; a mounting upright plate, welded to the upper surface of the mounting base plate; a clamping plate, rotatably connected to the opposite side of the mounting upright plate via a rotating column welded to its back; three sets of movable slots, radially arranged on the clamping plate; and three sets of clamping blocks, movably mounted in the movable slots; wherein anti-slip pads are adhered to the opposite surfaces of the three sets of clamping blocks.

[0009] The technical effect of adopting the above-mentioned further solution is that, by using three sets of clamping blocks that are movably installed in the movable slot, when it is necessary to fix the wheel hub, simply place the wheel hub between the two clamping discs of the two sets of clamping disc assemblies, and use the three clamping blocks at both ends to move closer to each other until the anti-slip pads on their inner end faces are stably attached to both ends of the wheel hub, thereby achieving stable fixation of the wheel hub.

[0010] Preferably, the clamp assembly further includes: a turbine connected to the end of the rotating column; a worm gear disposed on one side of the turbine gear and rotatably connected to the back of the mounting plate; and a second motor disposed at one end of the worm gear, with the output end of the second motor connected to one end of the worm gear; wherein the worm gear and the turbine gear mesh with each other.

[0011] The technical effect of adopting the above-mentioned further solution is that after the two ends of the wheel hub are fixed between the two clamping plate assemblies by the clamping block, if it is necessary to start the test, only the second motor needs to be started; the worm gear meshes with the turbine to rotate, and then the rotating column causes the clamping plate and clamping block holding the two ends of the wheel hub to rotate, thereby improving the detection speed of the device and avoiding manual rotation.

[0012] Preferably, the detection component includes: a robotic arm disposed on one side of the clamping plate; a dial indicator mounted on the free end of the robotic arm; and a detection needle mounted on the end of the dial indicator; wherein the dial indicator and the detection needle are connected by a thread.

[0013] The technical advantage of the above-mentioned further solution is as follows: First, the dial indicator is installed on the free end of the robotic arm. Then, using the threaded interface at the end of the dial indicator, the top of the testing probe is screwed into the probe interface and tightened until there is no looseness. During this process, the coaxiality of the testing probe and the probe must be ensured. The robotic arm then moves freely with the dial indicator and testing probe to adapt to the testing requirements of different wheel hubs. During testing, the dial indicator is rotated until its pointer returns to zero. Then, the robotic arm is slowly adjusted so that the head of the testing probe gently presses against the surface of the wheel hub. The roundness of the wheel hub is determined by observing the pointer of the dial indicator.

[0014] Preferably, the detection assembly further includes: a hydraulic shaft, mounted on the upper surface of the mounting bracket via a bracket; a telescopic rod, disposed above the hydraulic shaft, with its end connected to the output end of the hydraulic shaft; and a connecting block, connected to the top of the telescopic rod; wherein the connecting block is connected to the fixed end of the robotic arm.

[0015] The technical effect of adopting the above-mentioned further solution is that the telescopic rod is driven by the hydraulic shaft to extend and retract in the vertical direction, thereby driving the robotic arm and the detection needle to adjust up and down, which facilitates the device to detect wheel hubs with different wheel heights.

[0016] Preferably, the clamping plate assembly further includes: a rotating block, rotatably mounted inside the clamping plate; threaded grooves, evenly distributed on the side of the rotating block near the clamping block; and a first locking tooth, formed on the lower end face of the clamping block; wherein the first locking tooth engages with the threaded groove.

[0017] The technical effect of adopting the above-mentioned further solution is that by rotating the rotating block, the clamping blocks can move closer or further apart under the meshing action of the first clasp and the threaded groove, thereby fixing the two ends of the wheel hub therein.

[0018] Preferably, the clamping plate assembly further includes: an adjusting block, rotatably mounted on the side of the rotating block away from the clamping block, with its end penetrating the outer wall of the clamping plate and extending outward; a second set of teeth, evenly distributed on the surface of the adjusting block; and a third set of teeth, evenly distributed on the side of the rotating block away from the clamping block; wherein the second and third teeth mesh with each other.

[0019] The technical effect of adopting the above-mentioned further solution is that by rotating the adjusting block, the second clasp tooth engages with the third clasp tooth, causing the rotating block to rotate, thereby realizing the mutual approach and movement between the three sets of clamping blocks.

[0020] Preferably, the clamping plate assembly further includes: an adjustment hole, which is formed at the end of the adjustment block; and an adjustment handle, which is movably installed in the adjustment hole; wherein the end of the adjustment handle cooperates with the interior of the adjustment hole.

[0021] The technical effect of adopting the above-mentioned further solution is that: the end of the adjustment handle is inserted into the adjustment hole, and by utilizing the fit between the adjustment handle and the adjustment hole, the adjustment handle is rotated, thereby driving the adjustment block to rotate around its own axis, and finally realizing the rotation of the rotating block.

[0022] Preferably, the clamping plate assembly further includes: a limiting block, welded to the bottom of the mounting base plate and slidably disposed inside the limiting guide groove; a bidirectional lead screw, rotatably mounted in the movable base; a first motor, disposed at one end of the bidirectional lead screw, and its output end connected to the end of the bidirectional lead screw; wherein the bidirectional lead screw and the middle part of the limiting block are connected by threads.

[0023] The technical effect of adopting the above-mentioned further solution is that: starting the first motor causes the bidirectional lead screw to rotate around its own axis, and the mounting base plate can move along the axis of the bidirectional lead screw under the action of the threaded connection between the limit block and the bidirectional lead screw, thereby realizing that the two clamping plates move closer or further apart to adapt to the fixing requirements of wheel hubs of different sizes.

[0024] Preferably, the novel movable wheel hub roundness measuring device further includes: four mounting supports, which are welded to the four corners of the lower end face of the mounting frame; casters, which are installed at the bottom of the clamping plate assembly; and push handles, which are welded to the back of the mounting frame.

[0025] The technical effect of adopting the above-mentioned further solution is that by installing casters at the bottom of the support column, the staff can push the device stably with the help of the push handle, and the casters make it easier for the staff to fix the device and prevent it from slipping.

[0026] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model can be flexibly moved to the production line station with the help of casters and push handles, so as to realize on-site and real-time inspection. After the wheel hub is produced, it can be quickly fixed by the clamping plate assembly and rotated by the motor. With the help of high-precision inspection components, the roundness inspection can be completed quickly.

[0027] On the other hand, this device supports on-demand inspection after production, eliminating the need for centralized queuing and the handling process. Workers can complete the inspection right next to the production line, without having to move the wheel hubs to a fixed inspection point, thus eliminating pallet handling, reducing labor costs, and preventing wheel hub damage due to collisions during transport, reducing material waste. Secondly, the device is highly automated, requiring minimal manual intervention in the inspection operation. The clamping plate assembly automatically adjusts the spacing and rotates via a motor drive, while the inspection component achieves automatic positioning via a robotic arm and hydraulic shaft. Workers only need to complete three simple steps: "place the wheel hub - start the equipment - read the data," requiring no specialized inspection skills, reducing the number of personnel required for inspection and lowering labor costs.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0031] Please see Figures 1-6 This embodiment provides a novel movable wheel hub roundness measuring device, the specific concept of which is as follows: A novel movable wheel hub roundness measuring device includes a mounting frame 1. The novel movable wheel hub roundness measuring device also includes: a push handle 2, a movable base 3, two sets of clamping plate assemblies 4, four mounting pillars 6, and four omnidirectional wheels 7.

[0032] Among them, the mounting frame 1 serves as the supporting foundation for the entire device, and the back of the frame is fixed with a push handle 2 by welding process, which makes it convenient for staff to hold and operate.

[0033] Meanwhile, mounting supports 6 are welded to the four corners of the lower end face of the mounting bracket 1, and each mounting support 6 is equipped with casters 7 at its bottom.

[0034] It should be noted that, thanks to the rolling characteristics of the casters 7, workers can easily move the device by pushing the handle 2. The casters 7 also have a stable locking function, which can effectively prevent the device from slipping during operation and ensure the safety of the testing operation.

[0035] The movable base 3 is fixedly installed on the upper surface of the mounting frame 1, and a limiting guide groove 8 is provided on its top for the clamping plate assembly 4 to slide.

[0036] Meanwhile, the two sets of clamping plate assemblies 4 are symmetrically arranged and slidably assembled in the limiting guide groove 8, and can move closer or further away from each other along the direction of the guide groove.

[0037] As examples, in this embodiment, each clamping plate assembly 4 includes a mounting base plate 401, a mounting upright plate 402, a limiting block 403, a bidirectional lead screw 404, a first motor 405, a clamping plate 406, three sets of movable slots 407, three sets of clamping blocks 408, a first clamping tooth 409, a rotating block 410, a threaded groove 411, an adjusting block 412, an adjusting hole 413, an adjusting handle 414, a second clamping tooth 415, a third clamping tooth 416, a rotating column 417, a worm gear 418, a worm 419, and a second motor 420.

[0038] The mounting base plate 401 is located above the movable base 3, and the limiting block 403 welded to its bottom is embedded in the limiting guide groove 8.

[0039] It should be noted that the middle part of the limit block 403 is connected to the bidirectional lead screw 404, which is rotatably installed inside the movable base 3, by a thread. One end of the bidirectional lead screw 404 is connected to the output end of the first motor 405 located on the outside of the movable base 3.

[0040] When the first motor 405 is started, the bidirectional lead screw 404 will rotate around its own axis, and drive the limit block 403 together with the mounting base plate 401 to move along the axis of the bidirectional lead screw 404 through the threaded transmission, thereby realizing the adjustment of the distance between the two sets of clamping plate assemblies 4 to adapt to the wheel hub fixing requirements of different lengths.

[0041] In addition, the mounting plate 402 is fixed to the upper end face of the mounting base plate 401 by welding, and the clamping plate 406 is rotatably connected to the opposite side of the mounting plate 402 by a rotating column 417 welded to its back.

[0042] The end of the rotating column 417 extends to the back of the mounting plate 402 and is connected to a turbine 418.

[0043] Meanwhile, a worm gear 419 is provided on one side of the turbine 418 and is rotatably connected to the back of the mounting plate 402. One end of the worm gear 419 is connected to the output end of the second motor 420, and the worm gear 419 and the turbine 418 mesh with each other to form a stable transmission structure.

[0044] The clamping plate 406 has three sets of movable slots 407 arranged radially, and a clamping block 408 is movably installed in each set of movable slots 407.

[0045] It should be noted that anti-slip pads are adhered to the opposite surfaces of the three clamping blocks 408, which can enhance the friction with the end face of the wheel hub and prevent slippage during clamping.

[0046] In addition, a first locking tooth 409 is provided on the lower end face of the clamping block 408, and a rotating block 410 is rotatably installed inside the clamping disk 406. The rotating block 410 is provided with threaded grooves 411 that mesh with the first locking tooth 409 on one side near the clamping block 408.

[0047] It should be noted that the threaded groove 411 is a spiral groove formed by a point moving away from the center point at a constant speed along the ray while rotating around the center point at a fixed angular velocity. On the plane, it presents a shape of "uniformly expanding outward from the center", and the pitch between two adjacent turns is exactly equal.

[0048] Meanwhile, an adjustment block 412 is provided on the side of the rotating block 410 away from the clamping block 408. The end of the adjustment block 412 extends outward through the outer wall of the clamping disk 406, and multiple sets of second locking teeth 415 are evenly distributed on its surface.

[0049] On the side corresponding to the rotating block 410, there are multiple sets of third locking teeth 416 that mesh with the second locking teeth 415.

[0050] The adjusting block 412 has an adjusting hole 413 at its end, and the end of the adjusting handle 414 is fitted into the adjusting hole 413 and can be movably installed therein.

[0051] In this embodiment, when fixing the wheel hub, the operator inserts the adjustment handle 414 into the adjustment hole 413, and rotates the adjustment handle 414 to drive the adjustment block 412 to rotate around its own axis. Through the meshing transmission of the second locking tooth 415 and the third locking tooth 416, the rotating block 410 is driven to rotate inside the clamping plate 406. When the rotating block 410 rotates, the threaded groove 411 on its surface interacts with the first locking tooth 409 at the lower end of the clamping block 408, causing the three sets of clamping blocks 408 to move closer to each other along the movable groove 407 until the anti-slip pads on the clamping blocks 408 are tightly attached to both ends of the wheel hub, thus achieving stable clamping and fixing of the wheel hub. Once the wheel hub is fixed, the second motor 420 is started, and its output drives the worm gear 419 to rotate. The worm gear 419 meshes with the turbine 418 to rotate synchronously, which in turn drives the clamping plate 406 and the clamped wheel hub to rotate together through the rotating column 417. This replaces the manual rotation operation, significantly improves the detection efficiency, and ensures the uniformity of the wheel hub rotation, providing stable detection conditions for subsequent roundness detection. Example

[0052] like Figures 1-6 As shown in Example 1, this example provides a novel movable wheel hub roundness measuring device, the specific concept of which is as follows: The new movable wheel hub roundness measuring device also includes two sets of detection components 5.

[0053] Among them, the two sets of detection components 5 are respectively installed on the upper surface of the mounting frame 1 and are symmetrically distributed on one side of the two sets of clamping plate components 4, corresponding to the position of the clamping plate 406.

[0054] As examples, in this embodiment, each detection assembly 5 includes a hydraulic shaft 501, a connecting block 502, a robotic arm 503, a dial indicator 504, a detection probe 505, and a telescopic rod 506.

[0055] The hydraulic shaft 501 is fixedly mounted on the upper end face of the mounting bracket 1 by a bracket.

[0056] It should be noted that the output end of the hydraulic shaft 501 is connected to the end of the telescopic rod 506, which extends vertically upward and has a connecting block 502 fixedly connected to its top.

[0057] Meanwhile, the connecting block 502 is connected to the fixed end of the robotic arm 503.

[0058] The free end of the robotic arm 503 is equipped with a dial indicator 504, and the end of the dial indicator 504 is fitted with a test needle 505 via a threaded connection.

[0059] It is important to note that during installation, the coaxiality of the probe 505 and the dial indicator 504 must be ensured to avoid affecting the detection accuracy due to installation deviations.

[0060] The hydraulic shaft 501 can drive the telescopic rod 506 to extend and retract in the vertical direction. Through the connecting block 502, it drives the robotic arm 503 to adjust up and down synchronously, thereby realizing the height adjustment of the dial indicator 504 and the detection needle 505 to adapt to the wheel hub inspection needs of different wheel heights.

[0061] In addition, the robotic arm 503 has multi-degree-of-freedom movement capabilities, which can drive the dial indicator 504 and the detection probe 505 to move freely in the horizontal direction, further expanding the detection range and ensuring that comprehensive inspection of wheel hubs of different diameters can be carried out.

[0062] In this embodiment, before performing roundness testing, the assembly and debugging of the testing component 5 must be completed: the dial indicator 504 is fixed to the free end of the robotic arm 503, and then the top of the testing needle 505 is screwed into the threaded interface at the end of the dial indicator 504 and tightened until there is no looseness to ensure a stable assembly. During debugging, the dial of the dial indicator 504 is rotated to make the pointer zero. Then, by controlling the hydraulic shaft 501 and the robotic arm 503, the position of the testing needle 505 is slowly adjusted so that its head gently presses against the surface of the wheel hub, ensuring that the contact pressure between the testing needle 505 and the surface of the wheel hub is moderate. When the clamping assembly 4 drives the wheel hub to rotate at a constant speed, the testing needle 505 always maintains contact with the surface of the wheel hub. The roundness deviation of the wheel hub surface will be transmitted to the dial indicator 504 through the testing needle 505 and is visually presented by the deflection of the pointer of the dial indicator 504. By observing the fluctuation range of the pointer of the dial indicator 504, the operator can accurately determine whether the roundness of the wheel hub meets the standard requirements.

[0063] Working Principle: This device is a new type of movable wheel hub roundness measuring device. In use, the device is first pushed to the working position using the push handle 2 on the back of the mounting frame 1, in conjunction with the casters 7 at the bottom of the mounting column 6. The casters 7 are then locked to prevent slippage. Next, the first motor 405 is started, causing it to drive the bidirectional lead screw 404 within the movable base 3 to rotate. Through threaded transmission, the limit block 403 moves along the limit guide groove 8, carrying the mounting base plate 401. The distance between the two sets of clamping plate assemblies 4 is adjusted to fit the length of the wheel hub to be tested.

[0064] The wheel hub is then placed between the two sets of clamping discs 406. The adjusting handle 414 is inserted into the adjusting hole 413 at the end of the adjusting block 412. The adjusting handle 414 is rotated to make the adjusting block 412 rotate. The second locking tooth 415 and the third locking tooth 416 mesh to drive the rotating block 410 to rotate. Then, with the help of the threaded groove 411 meshing with the first locking tooth 409, the three sets of clamping blocks 408 move closer along the movable groove 407 until the anti-slip pads are attached to both ends of the wheel hub, thus completing the fixation.

[0065] Next, debug the testing component 5: Install the dial indicator 504 on the free end of the robotic arm 503, screw the testing needle 505 into the end of the dial indicator 504 and ensure coaxiality, then rotate the dial indicator 504 to zero. Start the hydraulic shaft 501 to drive the telescopic rod 506 to adjust the connecting block 502 and the robotic arm 503 up and down, then adjust the horizontal position of the robotic arm 503 so that the head of the testing needle 505 lightly presses against the surface of the wheel hub.

[0066] Finally, the second motor 420 is started, which drives the worm gear 419 to rotate. Through engagement with the turbine 418, the rotating column 417, along with the clamping plate 406 and the wheel hub, rotates at a constant speed. The operator observes the fluctuation of the dial indicator 504 to determine whether the wheel hub roundness is up to standard. After the inspection is completed, the motor is turned off, the adjustment handle 414 is operated in reverse to release the clamping block 408, the wheel hub is removed, and the swivel caster 7 is unlocked to push the device to its storage location.
