Description
Technical Field
[0001] This utility model relates to automotive stabilizer bar manufacturing technology, and more particularly to technology for detecting the shape and size of automotive stabilizer bars. Background Technology
[0002] The stabilizer bar assembly is a component mounted on the chassis suspension of a passenger car, which relies on its rigidity to suppress body roll. Figure 1 and Figure 2 The diagrams show the appearance of the processed stabilizer bar from different angles. As shown, the stabilizer bar 9 includes a central shaft 9a, a pair of bends 9b, and a pair of end caps 9c. One end of each bend 9b is connected to both ends of the central shaft 9a, and one end of each end cap 9c is connected to the other end of each bend 9b, extending towards the rear of the central shaft. The central shaft 9a includes a main shaft section 91, a pair of inclined sections 92, and a pair of straight sections 93. The main shaft section 91 extends in a straight line. One end of each inclined section 92 is connected to both ends of the main shaft section 91, and each inclined section 92 extends inclinedly upwards and forwards towards the main shaft section 91. One end of each straight section 93 is connected to the other end of each inclined section 92, and each straight section 93 extends in a direction parallel to the main shaft section 91. The other ends of each straight section 93 are connected to one end of each bend 9b. Each end 9c of the pole includes a front section 95 and a rear section 96. One end of the front section 95 is connected to the other end of the bend head 9b, and the front section 95 extends horizontally behind the middle shaft 9a. One end of the rear section 96 is connected to the other end of the front section 95, and the rear section 96 extends obliquely behind and above the front section 95.
[0003] After processing, the stabilizer bar needs to be inspected for its shape and dimensions. The existing inspection method mainly relies on manual placement of the stabilizer bar into a fixture for visual inspection, which is not only inefficient but also prone to misjudgment and omissions, resulting in poor accuracy of the inspection results.

[0005] The automatic stabilizer bar detection device of this utility model includes a detection platform, a stabilizer bar lifting mechanism, multiple calibration block assemblies, multiple sets of detection sensors, a controller, and a loading / unloading mechanism. The detection platform is provided with multiple detection blocks, each with a detection slot on its top surface to accommodate the corresponding part of the stabilizer bar to be tested.

Each calibration block assembly is disposed in the detection slot of the multiple detection blocks. The stabilizer bar has a side panel including a calibration block and a calibration block drive mechanism.

[0012] Figure 7 An electrical control schematic diagram of an automatic stabilizer bar detection device according to an embodiment of the present invention is shown. Detailed Implementation
[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0014] Figures 3 to 6 A structural diagram of an automatic stabilizer bar detection device according to an embodiment of the present invention is shown, and a schematic diagram of the electrical control principle of the automatic stabilizer bar detection device according to an embodiment of the present invention is shown. Please refer to [the diagram]. Figures 3 to 7 According to an embodiment of the present invention, the automatic detection device for stabilizer bars includes a detection platform 1, a stabilizer bar lifting mechanism 3, multiple calibration block assemblies, multiple sets of detection sensors, a controller 6, and a loading and unloading mechanism.
[0015] The testing platform 1 is equipped with multiple testing blocks, each with a testing slot 2b on its top surface to accommodate the corresponding part of the stabilizer 9 to be tested. In this embodiment, the multiple testing blocks include a pair of first testing blocks 21, a pair of second testing blocks 22, a pair of third testing blocks 23, and a pair of fourth testing blocks 24. When a qualified stabilizer 9 is placed in the testing slots of the pair of first testing blocks 21, the pair of second testing blocks 22, the pair of third testing blocks 23, and the pair of fourth testing blocks 24, the pair of first testing blocks 21, the pair of second testing blocks 22, the pair of third testing blocks 23, and the pair of fourth testing blocks 24 are symmetrically positioned on both sides of the centerline of the qualified stabilizer 9. The contours of the detection slots 2b of a pair of first detection blocks 21 are respectively adapted to a portion of the main rod section 91 of the qualified stabilizer bar; the contours of the detection slots 2b of a pair of second detection blocks 22 are respectively adapted to a portion of a pair of inclined sections 92 of the qualified stabilizer bar; the contours of the detection slots 2b of a pair of third detection blocks 23 are respectively adapted to a portion of a pair of bent heads 9b of the qualified stabilizer bar; and the contours of the detection slots 2b of a pair of fourth detection blocks 24 are respectively adapted to a portion of a pair of end rod sections 96 of the qualified stabilizer bar.
[0016] The stabilizer bar lifting mechanism 3 includes a bracket 31 and a bracket lifting drive mechanism. The bracket lifting drive mechanism is connected to the bracket 31 and is used to drive the bracket 31 to lift and lower, so as to lift the stabilizer bar 9 placed in the detection slots 2b of the multiple detection blocks or to place the stabilizer bar 9 in the detection slots 2b of the multiple detection blocks. In this embodiment, the bracket lifting drive mechanism includes a bracket drive cylinder 32, which is vertically arranged and connected to the bracket 31. Further, the stabilizer bar lifting mechanism 3 also includes a bracket lifting guide mechanism, which includes a pair of guide rods 33 and a pair of guide sleeves 34. The pair of guide rods 33 can slide through the pair of guide sleeves 34 respectively. The upper ends of the pair of guide rods 33 are connected to the bracket 31, and the top ends of the pair of guide sleeves 34 are fixedly connected to the detection table 1.
[0017] Each calibration block assembly is positioned to the side of the stabilizing rod 9, which is placed in the detection slot 2b of multiple detection blocks. Each calibration block assembly includes a calibration block 4a and a calibration block driving mechanism. The calibration block driving mechanism is used to drive the calibration block 4a to extend or retract, thereby detecting whether the calibration block 4a collides and interferes with the stabilizing rod 9 when it extends. The validity of the stabilizing rod 9 is determined based on whether the calibration block 4a collides and interferes with the stabilizing rod 9 when it extends. When the stabilizing rod 9 under test cannot be correctly placed in the detection slot 2b of multiple detection blocks due to factors such as shape or size errors, the extended calibration block 4a will collide and interfere with the stabilizing rod under test. Optionally, the calibration block driving mechanism includes a calibration block driving cylinder 4b, which is horizontally positioned. The push rod of the calibration block driving cylinder 4b is connected to the calibration block 4a. The calibration block driving cylinder 4b is equipped with a position detection component for detecting the extension and retraction position of the cylinder push rod. The signal output terminal of the position detection component is connected to the input terminal of the controller 6. This position detection component is, for example, a magnetic ring induction switch (the cylinder push rod is equipped with a magnetic ring) or a position sensor.
[0018] In this embodiment, the plurality of verification block components include a pair of first verification block components 41 and a pair of second verification block components 42. The pair of first verification block components 41 are located outside the pair of fourth detection blocks 24, and the pair of second verification block components are located in front of the pair of straight rod segments 93.
[0019] Multiple sets of detection sensors are used to detect whether the height of the stabilizing rod 9 placed in the detection slots 2b of multiple detection blocks is qualified. In this embodiment, the multiple sets of detection sensors include multiple sets of through-beam photoelectric switches 51, with the transmitter and receiver of each set of through-beam photoelectric switches 51 respectively disposed on the front and rear sides of the stabilizing rod 9 placed in the detection slots of multiple detection blocks. Further, the multiple sets of detection sensors also include multiple sets of distance sensors 52, which are respectively disposed below the stabilizing rod 9 placed in the detection slots of multiple detection blocks.
[0020] In the example shown in the figure, there are five sets of through-beam photoelectric switches 51 and two sets of distance sensors 52. The figure shows a first bracket 53 for supporting the transmitters of the through-beam photoelectric switches and a second bracket 54 for supporting the receivers. The transmitters and receivers of the first set of through-beam photoelectric switches 51 are respectively positioned in front of and behind the main rod section 91. The transmitters and receivers of the second and third sets of through-beam photoelectric switches are respectively positioned in front of and behind a pair of second detection blocks 22. The transmitters and receivers of the fourth and fifth sets of through-beam photoelectric switches are respectively positioned in front of and behind a pair of third detection blocks 23. The two sets of distance sensors 52 are respectively positioned below the main rod section 91. When the stabilizer 9 being measured cannot be correctly placed into the detection slots 2b of the multiple detection blocks due to factors such as shape or size errors, the laser emitted by the transmitter of the through-beam photoelectric switch will be blocked by the stabilizer 9, and the distance value measured by the distance sensor 52 will exceed the predetermined distance range.
[0021] The controller 6 is communicatively connected to the loading and unloading mechanism, which is used to place the stabilizer bar 9 to be tested on the bracket 31 and to remove the stabilizer bar after testing from the bracket 31. The controller 6 is used to receive the detection signals output by the multiple sets of detection sensors and to control the operation of the bracket lifting drive mechanism and the verification block drive mechanism of the multiple verification block assemblies. In this embodiment, the controller 6 is a PLC controller, and the loading and unloading mechanism uses a robot 7. The robot 7 includes a robot body 71 and a robot control cabinet 72, and the PLC controller is communicatively connected to the robot control cabinet 72. The robot 7 can be, for example, a six-axis robot.
[0022] The following describes the detection process of an automatic stabilizer bar detection device according to an embodiment of this utility model.
[0023] Robot 7 places the stabilizer bar 9 to be tested onto bracket 31. Controller 6 controls bracket drive cylinder 32 to retract, causing bracket 31 to descend and the stabilizer bar 9 to be placed into the detection slot 2b of multiple detection blocks. Subsequently, controller 6 controls the push rod of the verification block drive cylinder 4b of all inspection block assemblies to push the verification block 4a outward. If the verification block 4a collides and interferes with the stabilizer bar 9, the magnetic ring induction switch or position sensor in the verification block drive cylinder 4b will not send a signal to controller 6 indicating that the push rod has reached its extension or retraction position. Furthermore, if the laser emitted by the through-beam photoelectric switch 51 is blocked, or if the distance measured by the distance sensor 52 exceeds the preset distance range in controller 6, it means that the shape and size of the stabilizer bar 9 being tested are unqualified. When controller 6 detects that the stabilizer bar is unqualified, it can issue alarm information in real time (such as audible and visual alarms), and can also display the specific abnormality on the display screen of controller 6, while simultaneously sending information indicating whether the stabilizer bar 9 is qualified to robot 7. After the inspection is completed, the controller 6 controls the bracket drive cylinder 32 to extend, causing the bracket 31 to be lifted. The robot 7 removes the stabilizer bar 9 that has completed the inspection from the bracket 31, and places the qualified stabilizer bar 9 in the qualified product area and the unqualified stabilizer bar 9 in the problem part area. The qualified stabilizer bar will proceed to the next process.
[0024] The automatic stabilizer bar inspection device of this utility model has a simple structure and high reliability. When inspecting stabilizer bars, the device only needs to place the stabilizer bar to be tested on the bracket by a robot, and the automatic stabilizer bar inspection device will automatically complete the inspection. It has a high degree of automation and inspection efficiency, good stability, and is not prone to errors. The inspection data can also be directly sent to the MES system.
[0025] The above description is a further illustration of the present invention in conjunction with specific embodiments and accompanying drawings. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can extend and deduce it according to actual use without departing from the content of the present invention. Therefore, the content of the above specific embodiments should not limit the scope of protection defined by the present invention.
