Description

Technical Field

[0001] This invention relates to the field of stabilizer bar bushing testing equipment, specifically to an automotive stabilizer bar bushing error prevention testing equipment and testing method. Background Technology

[0002] The stabilizer bar bushing is located at the junction of the stabilizer bar and the vehicle body, serving a cushioning and shock absorption function. It absorbs and reduces the impact and vibration transmitted from the stabilizer bar to the vehicle body, lessening the bumpy feeling for the driver and passengers and improving ride comfort. In addition, the stabilizer bar bushing also reduces friction and wear between the stabilizer bar and the vehicle body, extending the stabilizer bar's lifespan. It prevents the stabilizer bar from directly contacting the vehicle's metal components, reducing noise and vibration transmission and protecting the integrity of the vehicle body.

[0003] The outer side of the car stabilizer bar bushing has a through-hole limiting hole. Its function is to install the bushing onto the stabilizer bar through the limiting hole line. After the car stabilizer bar bushing is manufactured, it generally needs to be inspected to avoid problems such as improper assembly due to non-standard manufacturing process or unqualified stabilizer bar bushing, which may cause bushing wear, deformation, breakage and other failures. The general inspection is manual inspection, which involves visually inspecting the inner and outer walls for scratches, burrs and other defects. This is inefficient, especially for the inner wall of the stabilizer bar bushing, which is difficult to observe. Summary of the Invention

[0036] Specifically, the flatness detection component 9 is as follows: Figure 6As shown, the flatness detection component 9 includes a vertical rod 91, a rotating shaft 93, and multiple sets of densely arranged contact detection elements.

[0038] To enable automatic feeding of the stabilizer bushing 6 to be tested, the present invention also includes a feeding conveyor belt 7, the output end of which is provided with two symmetrically arranged inclined plates 71; the distance between the two inclined plates 71 gradually decreases; the two inclined plates 71 are used to place the stabilizer bushing 6 at the center of the feeding conveyor belt 7.

[0039] To facilitate the separate output of qualified (superior) and unqualified (inferior) products, the present invention further includes a first discharge conveyor belt 5 and a second discharge conveyor belt 8, which are disposed on both sides of the feed conveyor belt 7; the first discharge conveyor belt 5 and the second discharge conveyor belt 8 are used to output superior and inferior products respectively.

The clamping assembly 4 is used to fix the stabilizer bushing 6 to be tested conveyed by the feed conveyor belt 7; the transfer assembly 3 is connected to the clamping assembly 4, and the transfer assembly 3 is used to move the stabilizer bushing 6 to be tested, held by the clamping assembly 4, to the surface of the rotary table 11; wherein, as shown... Figure 2 and Figure 3As shown, the clamping assembly 4 includes an insert rod 41, a second pneumatic telescopic rod 42, a stop plate 43, a slide rod 44, a limiting plate 45, a spring 46, and a first ranging assembly 47.

[0042] This invention also proposes a method for preventing errors in the detection of automotive stabilizer bar bushings, including...

[0043] Place the car stabilizer bar bushing 6 on the surface of the rotary table 11;

[0044] Place the two flatness detection components 9 on the inner and outer sides of the stabilizer bushing 6 respectively, and make them contact the inner and outer walls;

[0045] The stabilizer bushing 6 is rotated by the rotary table 11. As the ball bearing 94 rolls inside and outside the stabilizer bushing 6, the pressure sensor 95 connected to the rotating rod 92 detects the pressure change of the ball bearing 94 during rolling and detects the flatness of the inner and outer surfaces of the stabilizer bushing 6.

[0046] When using the stabilizer bar bushing 6 of the present invention, the first step is to load the material. During loading, the stabilizer bar bushing 6 to be tested is placed on the surface of the feeding conveyor belt 7 for conveying. During the conveying process, due to the obstruction of the inclined plate 71, the stabilizer bar bushing 6 is placed at the center position of the feeding conveyor belt 7.

[0047] Then, the stabilizer bushing 6 is transferred to the surface of the rotary table 11. During the transfer, the pneumatic slider 35 is activated to slide on the pneumatic slide rail 36, so that the clamping assembly 4 is aligned with the center position of the stabilizer bushing 6. Then, the first pneumatic telescopic rod 32 is activated, so that the insertion rod 41 is aligned with and contacts the center hole of the stabilizer bushing. Finally, the second rotary motor 34 is activated, which drives the clamping assembly 4 to rotate, so that the limiting plate 45 is aligned with the limiting hole on the side of the stabilizer bushing. Then, the first pneumatic telescopic rod 32 is continued to be driven, so that the limiting plate 45 is inserted into the limiting hole of the stabilizer bushing. When inserted, the stabilizer bushing pushes the slide rod 44 to move upward. The height of the stabilizer bushing is indirectly detected by the first ranging assembly 47 measuring the distance between the stabilizer bushing and the connecting rod 33.

[0048] Then the second pneumatic telescopic rod 42 is activated. When the second pneumatic telescopic rod 42 is activated, it pushes the two abutment plates 43 against the inner wall of the stabilizer bushing. Then, through the cooperation of the first pneumatic telescopic rod 32, the material transfer pneumatic slider 35, and the material transfer pneumatic slide rail 36, the clamping assembly 4 is clamped and transferred to the surface of the rotary table 11; the clamping assembly 4 is reset.

[0049] Subsequently, by moving component 2, the two flatness detection components 9 are brought into contact with the inner and outer walls of the stabilizer bar bushing. During the detection process, for example, as shown... Figure 7 As shown, taking the detection of the inner wall as an example, the rotary table 11 rotates clockwise. When a groove appears on the inner wall of the stabilizer bar bushing, the ball bearing 94 of the contact detection element at this point does not contact the stabilizer bar bushing or only partially contacts it. According to the lever law, the pressure of the pressure sensor of the contact detection element decreases at this time, and the detection data is transmitted to the display screen through the controller. When a burr appears, the ball bearing 94 of the contact detection element at this point contacts the stabilizer bar bushing and presses against it. According to the lever law, the pressure of the pressure sensor of the contact detection element increases at this time, and the detection data is transmitted to the display screen through the controller. The stability bar bushing is judged to be qualified based on whether the pressure value is within a reasonable range. At the same time, the thickness of the stability bar bushing is detected by the second ranging component 10, and the thickness is judged to be qualified by the controller.

[0050] After inspection, the products are transferred to the first discharge conveyor belt 5 or the second discharge conveyor belt 8 via the transfer component 3 and the clamping component 4.

[0051] Both the first ranging component 47 and the second ranging component 10 employ laser ranging technology.
