Description

Technical Field

[0001] This utility model relates to the field of testing technology for steering wheel frames, specifically to a testing device for steering wheel frames. Background Technology

[0002] In the automotive manufacturing industry, the steering wheel frame, as the core supporting structure of the steering wheel, directly affects the steering wheel's handling performance and driving safety. With the continuous expansion of automobile production scale and consumers' increasing demands for vehicle quality, the need for efficient and accurate testing of steering wheel frames is becoming increasingly urgent.

[0003] Currently, traditional steering wheel frame inspection methods have many obvious drawbacks. In the positioning and placement stage, most rely on manual operation, placing the steering wheel frame on the inspection table and relying on the worker's experience to judge whether the placement position is accurate. This method is not only inefficient, but also difficult to guarantee the consistency of each placement due to human factors, which can easily lead to deviations in subsequent inspections. For example, in large-scale production lines, it takes a long time to manually place a steering wheel frame, which seriously affects the overall production rhythm. Utility Model Content

[0004] The purpose of this invention is to provide a detection device for steering wheel frames, which solves the technical problems of low detection efficiency and insufficient detection accuracy in traditional steering wheel frame detection methods, and achieves the goal of accurately and effectively detecting steering wheel frames.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detection device based on a steering wheel frame, comprising a detection housing, a detection placement sensor, and an infrared transmitter calibration unit. Supporting legs are fixedly installed at equal intervals around the bottom outer wall of the detection housing, and a supporting pad is fixedly installed at the other end of each supporting leg. The detection placement sensor is respectively disposed on the top and inside of the detection housing; the infrared transmitter calibration unit is disposed on the top of the detection housing.

[0006] Preferably, the detection placement sensing unit specifically includes: a steering wheel frame body, disposed on the top of the detection box; a conical fitting block, fixedly installed on the top outer wall of the detection box; a wheel rim placement groove, formed on the top outer wall of the detection box; a control panel, disposed on one side outer wall of the detection box; a drive motor, fixedly installed on the bottom of the inner wall of the detection box; a guide slide rod, fixedly installed between the inner walls of the detection box; an ejector guide sleeve, circumferentially and equidistantly fixed on the top of the inner wall of the detection box; and a lifting adjustment frame, disposed inside the detection box.

[0007] A tapered fitting block is incorporated, its shape perfectly suited to the steering wheel frame, allowing for a tight fit to specific areas of the frame. When the steering wheel frame is placed on the testing device, the tapered fitting block guides it into precise positioning, ensuring the frame is in a standard position during testing. This prevents errors in the test results due to placement deviations, significantly improving the accuracy of the testing and positioning. For pressure testing, pressure sensors are fixedly installed in symmetrically designed mounting slots on the tapered fitting block. These sensors sensitively detect pressure changes at the contact points between the steering wheel frame and the tapered fitting block. By collecting and analyzing the pressure data, it is possible to determine whether the force on the corresponding parts of the steering wheel frame is uniform.

[0008] Preferably, the conical fitting block has symmetrically provided mounting grooves, and a pressure sensor is fixedly installed inside the mounting groove. The bottom circumference of the inner wall of the wheel rim placement groove has equidistantly provided ejector arc-shaped openings, and the bottom circumference of the inner wall of the wheel rim placement groove has equidistantly provided mounting circular grooves. The inner wall of each mounting circular groove is fixedly installed with a pressure sensor.

[0009] A rim placement slot is provided, which is adapted to fit the rim of the steering wheel frame body. This allows operators to quickly and accurately place the steering wheel frame on the testing device without complicated positioning operations, saving preparation time before testing. Moreover, the rim placement slot works in conjunction with the lifting and adjusting frame. After testing, the lifting and adjusting frame can lift the steering wheel frame to a certain height through the arc-shaped ejection plate and arc-shaped opening, making it easy for operators to remove the frame. In conjunction with the pressure sensor, it can detect the rim curvature. When the rim is placed in the rim placement slot, the pressure sensor can sense the pressure at various points when the rim contacts the slot. Since the pressure distribution differs between rims with different curvatures and the placement slot, analyzing the pressure data provides a key basis for determining whether the rim curvature meets the standard.

[0010] Preferably, the rim placement groove is adapted to the rim of the steering wheel frame body, the conical fitting block is adapted to the steering wheel frame body, the ejector guide sleeve is adapted to the ejector arc-shaped through-hole, a threaded sleeve is fixedly installed on the top outer wall of the lifting adjustment frame, a threaded screw is fixedly connected to the output end of the drive motor, and the other end of the threaded screw is rotatably connected to the top of the inner wall of the detection box.

[0011] Preferably, the lifting adjustment frame is threadedly connected to the threaded screw via a threaded sleeve, and a sliding sleeve is equidistantly fitted on the bottom outer wall of the lifting adjustment frame. The lifting adjustment frame is slidably connected to the guide slide rod via the sliding sleeve, and an arc-shaped ejector plate is fixedly fitted on the top outer wall of the lifting adjustment frame at equal intervals. The arc-shaped ejector plate is adapted to the ejector arc-shaped opening and the ejector guide sleeve, respectively.

[0012] Preferably, the infrared transmitter calibration unit specifically includes: a first support fixing block, which is fixedly installed on the top outer wall of the detection box; a second support fixing block, which is fixedly installed on the top outer wall of the detection box; and rectangular adjustment slides, which are respectively opened on one side outer wall of the first support fixing block and the second support fixing block.

[0013] Preferably, a hexagonal threaded sleeve is fixedly installed on the top outer wall of both the first and second support fixing blocks. The hexagonal threaded sleeve is connected to a rectangular adjusting groove. A threaded adjusting rod is threadedly connected to the inside of the hexagonal threaded sleeve, and one end of the threaded adjusting rod extends to the top of the hexagonal threaded sleeve.

[0014] Preferably, one end of the threaded adjusting rod is fixedly connected to a rotating wheel, and the other end of the threaded adjusting rod extends into the interior of the rectangular adjusting groove through a hexagonal threaded sleeve. The other end of the threaded adjusting rod is rotatably connected to the inner wall of the rectangular adjusting groove. A rectangular slider is slidably installed inside the rectangular adjusting groove. A threaded connecting sleeve is fixedly installed on the top of the rectangular slider. The rectangular slider is threadedly connected to the threaded adjusting rod through the threaded connecting sleeve. An infrared transmitter and an infrared receiver are fixedly installed on the outer wall of the rectangular slider.

[0015] An infrared transmitter and receiver are installed in the testing device. Components such as the support fixing block, rectangular adjustment groove, and threaded adjustment rod in the device create a flexible calibration system for the infrared transmitter and receiver. During actual testing, the positions of the infrared transmitter and receiver can be adjusted by rotating the wheel to adjust the threaded adjustment rod, depending on the size and shape differences of different steering wheel frame models.

[0016] This invention provides a detection device based on a steering wheel frame. It has the following advantages:

[0017] (1) This utility model achieves precise positioning of the frame by using a conical fitting block and a wheel rim placement groove that are adapted to the steering wheel frame body. The pressure sensor one on the conical fitting block and the pressure sensor two at the bottom of the inner wall of the wheel rim placement groove can accurately sense the contact between the frame and the corresponding part. This precise positioning not only ensures that the detection placement sensing part can simultaneously acquire multiple sets of data related to the steering wheel frame in the subsequent detection process, but also allows the pressure data fed back by the pressure sensors one and two to be used to evaluate the stability and fit of the frame installation and to determine whether the installation is too loose or too tight.

[0018] (2) This utility model constructs a flexible adjustment system by using the support fixing block one, support fixing block two and rectangular adjustment groove opened on them in the infrared transmitter calibration part, combined with hexagonal threaded sleeve and threaded adjustment rod. In the actual testing process, when facing steering wheel frames of different models and sizes, the operator only needs to turn the wheel to easily adjust the threaded adjustment rod. The rotation of the threaded adjustment rod drives the rectangular slider connected to it to slide in the rectangular adjustment groove, thereby adjusting the position of the infrared transmitter and receiver.

[0024] 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.

[0025] Examples of the embodiments 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.

[0026] Example 1:

[0027] Addressing the issues of low efficiency and insufficient accuracy in existing traditional steering wheel frame detection methods, this invention provides a preferred embodiment of a steering wheel frame detection device, for example... Figures 1-4 As shown: A detection device based on a steering wheel frame includes a detection housing 1, a detection placement sensor 3, and an infrared transmitter calibration unit 4. Supporting and fixing legs 2 are fixedly installed equidistantly on the bottom outer wall of the detection housing 1, and supporting and fixing pads are fixedly installed at the other end of the supporting and fixing legs 2. The detection placement sensor 3 is respectively disposed on the top and inside of the detection housing 1. The infrared transmitter calibration unit 4 is disposed on the top of the detection housing 1.

[0028] The detection placement sensor unit 3 specifically includes: a steering wheel frame body 311, which is disposed on the top of the detection box 1; a conical fitting block 312, which is fixedly installed on the top outer wall of the detection box 1; a wheel rim placement groove 314, which is formed on the top outer wall of the detection box 1; a control panel 316, which is disposed on one side outer wall of the detection box 1; a drive motor 318, which is fixedly installed on the bottom of the inner wall of the detection box 1; a guide slide rod 319, which is fixedly installed between the inner walls of the detection box 1; an ejector guide sleeve 3111, which is fixedly installed circumferentially at equal intervals on the top of the inner wall of the detection box 1; and a lifting adjustment frame 3113, which is disposed inside the detection box 1.

[0029] The conical mating block 312 has symmetrically opened mounting grooves, and a pressure sensor 313 is fixedly installed inside the mounting groove. The inner wall of the wheel rim placement groove 314 has equidistantly opened ejector arc-shaped openings 317 on the bottom circumference. The inner wall of the wheel rim placement groove 314 has equidistantly opened mounting circular grooves on the bottom circumference. A pressure sensor 315 is fixedly installed on the inner wall of each mounting circular groove.

[0030] The rim placement groove 314 is adapted to the rim of the steering wheel frame body 311, the conical fitting block 312 is adapted to the steering wheel frame body 311, the ejector guide sleeve 3111 is adapted to the ejector arc-shaped through-hole 317, the top outer wall of the lifting adjustment frame 3113 is fixedly installed with a threaded sleeve 3114, the output end of the drive motor 318 is fixedly connected with a threaded screw 3112, and the other end of the threaded screw 3112 is rotatably connected to the top of the inner wall of the detection box 1.

[0031] The lifting adjustment frame 3113 is threadedly connected to the threaded screw 3112 via the threaded sleeve 3114. The bottom outer wall of the lifting adjustment frame 3113 is equidistantly fitted with a sliding sleeve. The lifting adjustment frame 3113 is slidably connected to the guide slide rod 319 via the sliding sleeve. The top outer wall of the lifting adjustment frame 3113 is equidistantly fitted with an arc-shaped ejection plate 3115. The arc-shaped ejection plate 3115 is adapted to the ejection arc-shaped opening 317 and the ejection guide sleeve 3111, respectively.

[0032] In this embodiment, the steering wheel frame body 311 is picked up and placed in the rim placement groove 314 on the top of the detection box 1, ensuring a precise fit between the rim and the groove. At this point, the center of the steering wheel frame body 311 is in contact with the conical fitting block 312. Pressure sensors 313, symmetrically installed in the grooves on the conical fitting block 312, begin to sense the fitting pressure. Pressure sensors 315, equidistantly installed in the circular grooves at the bottom circumference of the inner wall of the rim placement groove 314, also simultaneously detect the contact pressure between the rim and the bottom of the groove. This pressure data is fed back to the system in real time to determine whether the steering wheel frame body 311 is properly positioned, allowing the operator to... It can quickly and accurately place the steering wheel frame on the testing device without complicated positioning operations, saving preparation time before testing. Moreover, the wheel rim placement groove works in conjunction with the lifting and adjusting frame, etc. After the test is completed, the lifting and adjusting frame can lift the steering wheel frame to a certain height through the arc-shaped ejection plate and arc-shaped opening, making it convenient for operators to remove the frame. In conjunction with the pressure sensor, it can detect the wheel rim curvature. When the wheel rim is placed in the wheel rim placement groove, the pressure sensor can sense the pressure at various points when the wheel rim contacts the groove. Since the pressure distribution of wheel rims with different curvatures is different when in contact with the placement groove, the pressure data can be analyzed to provide key evidence for determining whether the wheel rim curvature meets the standard.

[0033] Example 2:

[0034] Please see Figures 1-4 Furthermore, based on Embodiment 1, the infrared transmitter calibration unit 4 specifically includes: a first support fixing block 411, which is fixedly installed on the top outer wall of the detection box 1; a second support fixing block 412, which is fixedly installed on the top outer wall of the detection box 1; and a rectangular adjustment slide 413, which is respectively opened on one side outer wall of the first support fixing block 411 and the second support fixing block 412.

[0035] Hexagonal threaded sleeves 415 are fixedly installed on the top outer walls of both support fixing block 1 411 and support fixing block 2 412. The hexagonal threaded sleeves 415 are connected to the rectangular adjusting slide 413. The internal threads of the hexagonal threaded sleeves 415 are connected to a threaded adjusting rod 414, one end of which extends to the top of the hexagonal threaded sleeves 415.

[0036] One end of the threaded adjusting rod 414 is fixedly connected to a rotating wheel 416, and the other end of the threaded adjusting rod 414 extends into the interior of the rectangular adjusting groove 413 through a hexagonal threaded sleeve 415. The other end of the threaded adjusting rod 414 is rotatably connected to the inner wall of the rectangular adjusting groove 413. A rectangular slider 417 is slidably installed inside the rectangular adjusting groove 413. A threaded connecting sleeve is fixedly installed on the top of the rectangular slider 417. The rectangular slider 417 is threadedly connected to the threaded adjusting rod 414 through the threaded connecting sleeve. An infrared transmitter 418 and an infrared receiver 419 are fixedly installed on the outer wall of the rectangular slider 417.

[0037] In this embodiment, according to the model and size of the steering wheel frame body 311, the operator rotates the wheel 416 fixedly connected to one end of the threaded adjustment rod 414 in the infrared transmitter calibration section 4. The threaded adjustment rod 414 rotates within the hexagonal threaded sleeve 415 fixedly installed on the top outer wall of the first support fixing block 411 and the second support fixing block 412. Since the hexagonal threaded sleeve 415 is connected to the rectangular adjustment groove 413, and the other end of the threaded adjustment rod 414 is rotatably connected to the inner wall of the rectangular adjustment groove 413, the rotating threaded adjustment rod 414 drives the rectangular slider 417 threadedly connected to it to slide within the rectangular adjustment groove 413. The infrared transmitter 418 and infrared receiver 419 fixedly installed on the outer wall of the rectangular slider 417 move accordingly until they are adjusted to a position suitable for the current steering wheel frame body 311 to be tested, thus completing the calibration. In the actual testing process, according to the size and shape differences of different models of steering wheel frames, the position of the infrared transmitter and receiver can be adjusted by rotating the wheel and adjusting the threaded adjustment rod.

[0038] Working principle: When in use;

[0039] Step 1: Place the detection device on a stable workbench, ensuring that the support legs 2, which are equidistantly fixed to the bottom outer wall of the detection box 1, provide stable support. The support pad at the other end of the support leg 2 should be in close contact with the table surface to prevent the device from shaking during operation. Check whether the components of the detection placement sensor 3 and the infrared transmitter calibration unit 4 are securely installed and properly connected.

[0040] Step 2: Pick up the steering wheel frame body 311 and place it in the rim placement groove 314 on the top of the detection box 1, so that the rim and the rim placement groove 314 are precisely matched. At this time, the center part of the steering wheel frame body 311 is in contact with the conical fitting block 312. The pressure sensor 313 symmetrically installed in the groove on the conical fitting block 312 begins to sense the fitting pressure. The pressure sensor 315 equidistantly installed in the circular groove at the bottom of the inner wall of the rim placement groove 314 also simultaneously detects the contact pressure between the rim and the bottom of the groove. These pressure data are fed back to the system in real time to determine whether the steering wheel frame body 311 is placed in place.

[0041] Step 3: According to the model and size of the steering wheel frame body 311, the operator rotates the wheel 416 fixedly connected to one end of the threaded adjustment rod 414 in the infrared transmitter calibration section 4. The threaded adjustment rod 414 rotates in the hexagonal threaded sleeve 415 fixedly installed on the top outer wall of the support fixing block 1 411 and the support fixing block 2 412. Since the hexagonal threaded sleeve 415 is connected to the rectangular adjustment slide 413 and the other end of the threaded adjustment rod 414 is rotatably connected to the inner wall of the rectangular adjustment slide 413, the rotating threaded adjustment rod 414 drives the rectangular slider 417 threadedly connected to it to slide in the rectangular adjustment slide 413. The infrared transmitter 418 and infrared receiver 419 fixedly installed on the outer wall of the rectangular slider 417 move accordingly until they are adjusted to a position suitable for the current detection of the steering wheel frame body 311, and the calibration is completed.

[0042] Step 5: After calibration, the infrared transmitter 418 emits an infrared signal of a specific frequency. The signal illuminates the key detection parts of the steering wheel frame body 311, such as the frame height. The reflected infrared signal is captured by the infrared receiver 419. The receiver transmits the received signal to the control system. The control system analyzes and processes the signal to calculate the relevant parameters of the steering wheel frame body 311, thereby determining whether the steering wheel frame meets the quality standards.

[0043] Step Six: After completing infrared detection and other related tests, the control system displays the test results through the control panel 316. The operator processes the steering wheel frame body 311 according to the test results. Qualified products are removed and proceed to the next process; unqualified products are marked and analyzed. The drive motor 318 is started, driving the threaded screw 3112 to rotate. The threaded sleeve 3114, fixedly installed on the top outer wall of the lifting adjustment bracket 3113, is threadedly connected to the threaded screw 3112. As the threaded screw 3112 rotates, the lifting adjustment... The frame 3113 begins to rise along the guide slide bar 319. The sliding sleeves equidistantly fitted around the bottom outer wall of the lifting and adjusting frame 3113 slide smoothly on the guide slide bar 319, playing a guiding and stabilizing role. As the lifting and adjusting frame 3113 rises, the arc-shaped ejector plate 3115 equidistantly fitted around the top outer wall gradually approaches and passes through the ejector arc-shaped opening 317, enters the ejector guide sleeve 3111, and applies an upward ejector force to the steering wheel frame body 311 placed in the wheel rim placement groove 314, thus ejecting the steering wheel frame body 311.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
