Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to a subframe bushing detection device. Background Art

[0002] Rubber bushings are widely used in automobile suspension systems, powertrains and motor assemblies. They have the function of reducing vibration and noise. At the same time, the suspension system uses rubber bushings to improve the chassis dynamics, making the vehicle suspension have good comfort and handling stability. The rubber bushing consists of an inner tube, a main body and an outer tube. The inner tube is made of metal, the main body is made of rubber structure, and some are provided with built-in cavity flow channel structure and filled with liquid. The outer tube is mostly made of metal and some are made of nylon. In use, the inner tube and outer tube of the rubber bushing are respectively installed on the base and the suspension rod on both sides of the bushing connection pair. The outer tube of the rubber bushing will be installed in the rigid sleeve through interference fit. The actual interference directly determines the difficulty of installation and the final anti-pullout ability of the connection pair. Therefore, the roundness and diameter of the outer tube of the rubber bushing need to have good dimensional accuracy to ensure the appropriate interference, so as to ensure a firm and reliable connection; in addition, the coaxiality tolerance of the inner tube and the outer tube cannot be too large, otherwise it will have an adverse effect on the effectiveness of the bushing and the size chain of the surrounding parts.

[0003] The rubber bushing must go through a complex production process, and its final process is rubber vulcanization molding. Vulcanization will cause large tensile stress inside the rubber. This internal stress will cause large fluctuations in the coaxiality of the inner and outer tubes and the roundness of the outer tube. The above coaxiality and diameter size tolerances will affect the press-fitting and pull-out force of the rubber bushing, thereby affecting the connection performance and the peripheral size chain distribution of the bushing. Therefore, the current production adopts a high-frequency factory inspection and 100% re-inspection before installation. Currently, rubber bushing inspection usually adopts three-coordinate random inspection and caliper random inspection of outer diameter to ensure the stability and reliability of the above-mentioned connection performance and dimension chain; however, the above two types of measurement have the following problems: 1. The three-coordinate measurement takes a long time, and there is a problem of low efficiency when performing a full inspection; 2. The random inspection adopts caliper measurement, and the outer diameter can only be roughly qualitatively evaluated through diagonal measurement. The measurement is not accurate, and the outer circle runout of the bushing cannot be accurately detected, and thus the coaxiality of the bushing cannot be accurately judged. Therefore, a detection device that can efficiently and accurately detect the outer circle runout of the bushing is needed. Summary of the invention

[0036] The technical solution of the present invention is further specifically described below by way of embodiments and in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "in", "out", "front", "back", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Example

[0038] refer to Figure 1 and Figure 2A subframe bushing detection device comprises a support device 10, the support device 10 comprises a support frame 101, a motor support frame 106 is arranged on the support frame 101, a rotating device 60 is installed on the side surface of the motor support frame 106, a second positioning device 50 and a first positioning device 40 are fixedly connected in sequence on the rotating device 60; a laser sensor 109 is arranged on the support frame 101, and the laser sensor 109 is directly opposite to the second positioning device 50; specifically, there are two laser sensors 109, and the two laser sensors 109 are fixedly installed on a laser connecting frame 108 (two upper and lower laser sensors 109 are used for measurement, so that one more detection value can be obtained, one sensor can also detect, but can only detect one outer diameter line of the outer circle of the bushing, two sensors can detect two lines up and down, thereby improving the detection accuracy), and the laser connecting frame 108 is fixedly installed in the middle of the support plate 104; the laser sensor 109 is used to detect the roundness or coaxiality of the bushing 100, and the second positioning device 50 and the first positioning device 40 cooperate to fix the bushing 100, so as to facilitate subsequent detection.

[0039] The method for the laser sensor 109 to detect the outer circle runout of the bushing 100 is as follows: Detecting the outer circle runout of the bushing 100 by using the laser sensor 109 is a non-contact measurement method, which uses the high directivity, high monochromaticity and high brightness of the laser to achieve accurate measurement of the outer circle runout of the object. The following are the general steps and methods for using the laser sensor to detect the outer circle runout of the bushing 100: Installation and calibration: First, the laser sensor 109 is installed at the position of the laser connecting frame 108 to ensure that it can accurately align with the outer cylindrical surface of the measured bushing 100. Then the laser sensor 109 is calibrated to ensure the accuracy of the measurement result.

[0040] Data collection: The laser sensor 109 is activated to emit laser pulses to the surface of the laser sensor 109. The laser sensor 109 receives the laser reflected from the surface of the object and converts the optical signal into an electrical signal through the built-in optical system and avalanche photodiode. These electrical signals are then stored in the storage module and processed by the main controller to obtain the distance information of the object.

[0041] Runout detection: During the rotation of the bushing 100, the laser sensor 109 continuously collects distance data. By analyzing this data, the runout of the outer circle of the bushing 100 can be detected. Usually, the runout value is obtained by calculating the difference between the maximum value and the minimum value in the measurement data.

[0042] Data processing: The collected data may be affected by noise, so data processing such as filtering and interpolation is required to remove noise and improve the accuracy of the data. After that, mathematical methods such as the least squares method can be used to fit the data to a curve to more accurately describe the outer circular contour of the object and calculate the runout value.

[0043] Result output: Finally, the calculated runout value is output to the human-computer interactive display or other display device for analysis and recording. The computer software can also provide data statistical analysis and graphic display functions to help users better understand and analyze the measurement results.

[0044] Accuracy guarantee: To ensure the accuracy of measurement, the laser sensor needs to have high resolution and high sampling frequency. At the same time, the installation position and angle of the sensor also need to be carefully adjusted to avoid the irregular reflection of the object surface affecting the measurement results.

[0045] Through the above steps, the laser sensor 109 can achieve accurate measurement of the outer circle runout of the bushing 100. This method is particularly suitable for applications that have high requirements for accuracy and are not suitable for contact measurement.

[0046] refer to Fig.14 The second positioning device 50 includes a first fixed disk 506, which is fixedly mounted on the rotating device 60. A limiting sleeve 501 is arranged on the first fixed disk 506. A rod column 505 is slidably mounted inside the limiting sleeve 501. A third electromagnet 510 is arranged on the upper surface of the first fixed disk 506, and the third electromagnet 510 is located inside the limiting sleeve 501. A second spring 507 is arranged between the rod column 505 and the third electromagnet 510, and one end of the second spring 507 is connected to the third electromagnet 510, and the other end is connected to the rod column 505; an inclined groove 5051 is arranged on the outer side of the rod column 505, and a clamping block 502 is slidably mounted inside the inclined groove 5051, and the clamping block 502 passes through the groove on the limiting sleeve 501 and contacts the inner wall of the bushing 100. Specifically, an iron block is provided at one end of the rod column 505 near the third electromagnet 510, and the third electromagnet 510 is energized, thereby attracting the rod column 505 to overcome the elastic force of the second spring 507 and move downward, thereby retracting the blocking block 502 into the limiting sleeve 501, making it convenient for the bushing 100 to be sleeved on the outside of the limiting sleeve 501; when the third electromagnet 510 is de-energized, the rod column 505 moves upward under the elastic force of the second spring 507, and the blocking block 502 moves toward the outside of the limiting sleeve 501 along the inclined groove 5051, thereby clamping the bushing 100 from the inside.

[0047] Please refer to Fig.15A limiting plate 503 is slidably installed on the outer side of the limiting sleeve 501, and a plurality of second electromagnets 509 are arranged at one end of the limiting plate 503 close to the first fixed plate 506. A first electromagnet 508 is arranged on the first fixed plate 506 at a position directly opposite to the second electromagnet 509. A first spring 504 is arranged between the limiting plate 503 and the first fixed plate 506, and both ends of the first spring 504 are respectively installed on the outer sides of the first electromagnet 508 and the second electromagnet 509. Specifically, by energizing the first electromagnet 508 and the second electromagnet 509, the first electromagnet 508 and the second electromagnet 509 generate a repulsive force, which causes the limit plate 503 to move upward, and then pushes up the bushing 100 on the outside of the limit sleeve 501, so that the upper end of the bushing 100 contacts the connecting plate 407, thereby completing the fixation of the bushing 100. When the first electromagnet 508 and the second electromagnet 509 are both de-energized, under the action of the gravity of the bushing 100, the bushing 100 will drive the limit plate 503 to overcome the spring force of the first spring 504 and move downward.

When the sliding block 404 drives the arc shell 403 to the uppermost end, the connecting rod 406 and the connecting plate 407 are unfolded into a nearly straight line. At this time, it is convenient for the bushing 100 to be sleeved on the outside of the arc shell 403, and then slide to the second positioning device 50 through the first positioning device 40. When the sliding block 404 drives the arc shell 403 to the lowermost end, the connecting rod 406 and the connecting plate 407 are folded and overlapped to nearly a straight line. At this time, it is convenient for the connecting plate 407 to support the uppermost end of the bushing 100, which is convenient for subsequent detection.

[0056] Working principle: When the present invention is used, the bushings 100 to be tested are placed in the discharge barrel 105 in sequence; When it is necessary to put the bushing 100 in the discharge barrel 105 onto the first positioning device 40, the first electric cylinder 302 contracts to drive the baffle plate 303 to leave the discharge barrel 105. At this time, the bushing 100 between the baffle plate 303 and the limit plate 305 falls onto the second positioning device 50 through the first positioning device 40, and then the first electric cylinder 302 extends to drive the baffle plate 303 to move into the discharge barrel 105, and then the second electric cylinder 304 contracts to drive the limit plate 305, so that the bushing 100 above the limit plate 305 falls onto the baffle plate 303, and then the second electric cylinder 304 extends to clamp the limit plate 305 between the two bushings 100; The bushing 100 falls onto the limiting plate 503 of the second positioning device 50 along the first positioning device 40 (at this time, the sliding block 404 drives the arc shell 403 to be at the uppermost end, and the connecting rod 406 and the connecting plate 407 are unfolded into a nearly straight line, which is convenient for the bushing 100 to be sleeved on the outer side of the arc shell 403, and then slide to the second positioning device 50 through the first positioning device 40). When the bushing 100 falls onto the limiting plate 503, the rodless electric cylinder 402 drives the sliding block 404 to drive the arc shell 403 to be at the lowermost end, and the connecting rod 406 and the connecting plate 407 are folded and overlapped. The first electromagnet 508 and the second electromagnet 509 are both energized, and the first electromagnet 508 and the second electromagnet 509 generate a repulsive force, thereby moving the limit plate 503 upward, and then pushing up the bushing 100 on the outside of the limit sleeve 501, so that the upper end of the bushing 100 contacts the connecting plate 407, and the bushing 100 is fixed. Then the third electromagnet 510 is powered off, and the rod column 505 moves upward under the elastic force of the second spring 507, and the clamping block 502 moves along the inclined groove 5051 toward the outside of the limit sleeve 501, thereby clamping the bushing 100 from the inside.

[0057] When the bushing 100 is fixed, the third motor 604 drives the second gear 603 to rotate the first gear 602, and the first gear 602 drives the second fixed plate 605 and the first positioning device 40 and the second positioning device 50 to rotate, and then drives the bushing 100 fixed on the second positioning device 50 to rotate, so as to facilitate the detection of the bushing 100 by the laser sensor 109; after the detection, When the bushing 100 is qualified, the first motor 107 drives the rotating device 60 and then drives the second positioning device 50 and the first positioning device 40, and then drives the bushing 100 on the second positioning device 50 to rotate 90 degrees, and then the rodless electric cylinder 402 of the first positioning device 40 drives the sliding ring 405 to move away from the rotating device 60, when the sliding block 404 drives the arc housing 403 to the uppermost end, the connecting rod 406 and the connecting plate 407 are unfolded into a nearly straight line, and at the same time the third electromagnet 510 is energized to move the rod column 505 toward the direction close to the third electromagnet 510, so that the block 502 is retracted into the limiting sleeve 501, and the bushing 100 falls into the large box above the collection box 201 along the first positioning device 40; When the detection sleeve 100 is unqualified, the second motor 203 drives the second electric cylinder 304 and then drives the collection box 201 so that the small box on the collection box 201 is located below the rotating device 60, and then the first motor 107 drives the rotating device 60 and then drives the second positioning device 50 and the first positioning device 40, and then drives the sleeve 100 on the second positioning device 50 to rotate 90 degrees, and then the rodless electric cylinder 402 of the first positioning device 40 drives the sliding ring 405 to move away from the rotating device 60, when the sliding block 404 drives the arc shell 403 to the uppermost end, the connecting rod 406 and the connecting plate 407 are unfolded into a nearly straight line, and at the same time the third electromagnet 510 is energized, so that the rod column 505 moves in the direction of the third electromagnet 510 and then the block 502 retracts into the limit sleeve 501, and the sleeve 100 falls into the small box above the collection box 201 along the first positioning device 40.

[0058] Then, the first motor 107 drives the rotating device 60 and then drives the second positioning device 50 and the first positioning device 40, and then drives the sleeve 100 on the second positioning device 50 to rotate 90 degrees, so that the second positioning device 50 is directly below the discharge barrel 105, and repeats the above steps to detect the next sleeve 100.
