Description

Technical Field

[0001] This invention belongs to the field of automotive braking system control ring technology, specifically, it relates to an automotive braking system control ring pressure testing device. Background Technology

[0002] In automotive braking systems, the control ring plays a crucial role, and its compressive strength directly affects the reliability and safety of the braking system. Traditional control ring compressive strength testing often relies on complex electronic sensing devices or hydraulic control systems. These methods are not only costly, but also require specialized technicians for maintenance and calibration, increasing the difficulty and cost of testing. Furthermore, electronic equipment may exhibit stability and interference issues in harsh industrial environments, affecting the accuracy of the test results. Therefore, developing a mechanically implemented automotive braking system control ring compressive strength testing device is of significant practical importance, and this invention is proposed accordingly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a vehicle braking system control ring pressure testing device that can overcome or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a pressure resistance testing device and method for an automotive braking system control ring, including a base, and a drive motor fixedly connected to the base. A lifting screw is rotatably connected to the output end of the drive motor, and a threaded seat is slidably connected to the lifting screw. A first pressing block and a second pressing block are fixedly connected to the threaded seat. A testing platform is fixedly connected to the base, and a spring pin is slidably connected to the testing platform. A clamping semicircular plate is slidably connected to the testing platform, and a measuring disk is fixedly connected to the testing platform. A scale is fixedly connected to the measuring disk. An automotive control ring is disposed on the testing platform, and a corresponding spring pin is disposed at the end of the automotive control ring near the testing platform. After the clamping semicircular plate clamps and fixes the automotive control ring, the spring pin moves into the interior of the automotive control ring, the drive motor drives the lifting screw to rotate, and the threaded seat moves closer to one end of the automotive control ring on the lifting screw. The first pressing block and the second pressing block on the threaded seat perform pressure resistance testing on the automotive control ring.

[0005] Furthermore, a limit block is fixedly connected to the lifting screw, which restricts the threaded seat from moving upward on the lifting screw.

[0006] Furthermore, multiple slide rods are fixedly connected to the threaded seat, slide sleeves are slidably connected to the slide rods, and a second pressing block is fixedly connected to the slide sleeves.

[0007] Furthermore, the testing platform has a through hole, a pin slot is fixedly connected to the testing platform, a rotating wheel is rotatably connected to the testing platform, a transverse screw is fixedly connected to the rotating wheel, a transverse pressing block is slidably connected to the transverse screw, a gear is fixedly connected to the transverse pressing block, a clamping gear meshes with the gear, a clamping rod is rotatably connected to the clamping gear, and a clamping semicircular plate is fixedly connected to the clamping rod. The two sets of clamping semicircular plates have different diameters.

[0008] Furthermore, a rubber block is fixedly connected to one end of the clamping semicircular plate near the vehicle control ring.

[0009] Furthermore, multiple pressure springs are fixedly connected to the measuring disc.

[0010] Furthermore, the spring pin is made of a magnetic material, while the automotive control ring is made of metal.

[0011] Furthermore, the method for testing the compressive strength of the control ring in an automotive braking system includes the following steps: The control wheel rotates, which drives the transverse screw to rotate. The transverse screw drives the transverse pressing block to move closer to one end of the wheel. The transverse pressing block drives the rack to move closer to one end of the wheel. The rack drives the clamping gear to rotate. The clamping rod drives the clamping semicircular plates to move away from each other. At this time, the car control ring is placed on the testing platform on the base. The car control ring pulls the spring pin in the pin slot and locks it inside the car control ring to prevent it from shifting. Then the wheel rotates in the opposite direction, and the clamping semicircular plates move closer to each other to clamp and fix the car control ring.

[0012] Furthermore, the method for testing the compressive strength of the control ring in an automotive braking system also includes the following steps: The drive motor drives the lifting screw to rotate. After the threaded seat on the lifting screw approaches the vehicle control ring, the three sets of second extrusion blocks on the threaded seat are visually inspected. The position of the sliding sleeve on the sliding rod is adjusted so that the second extrusion blocks are on the surface of the vehicle control ring. The drive motor is started again, and the first and second extrusion blocks simultaneously exert pressure on the vehicle control ring on the testing platform.

[0013] Furthermore, the method for testing the compressive strength of the control ring in an automotive braking system also includes the following steps: When the vehicle control ring is squeezed by the first and second squeezing blocks, the pressure spring on the testing platform is simultaneously squeezed by the vehicle control ring. When the pressure spring is under downward force inside the measuring disc, the pressure spring can be directly observed through the scale on the measuring disc to record the vehicle's pressure resistance data.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention controls the rotating wheel to rotate, the rotating wheel drives the transverse screw to rotate, the transverse screw drives the transverse extrusion block to move closer to one end of the rotating wheel, the transverse extrusion block drives the rack to move closer to one end of the rotating wheel, the rack drives the clamping gear to rotate, and the clamping rod drives the clamping semicircular plates to move away from each other. At this time, the car control ring is placed on the detection table on the base. The car control ring pulls the spring pin in the pin groove and locks it inside the car control ring to prevent the car control ring from shifting. Then the rotating wheel is rotated in the opposite direction, and the clamping semicircular plates move closer to each other to clamp and fix the car control ring.

[0015] The drive motor drives the lifting screw to rotate. After the threaded seat on the lifting screw approaches the vehicle control ring, the three sets of second extrusion blocks on the threaded seat are visually inspected. The position of the sliding sleeve on the sliding rod is adjusted so that the second extrusion blocks are on the surface of the vehicle control ring. The drive motor is started again, and the first and second extrusion blocks simultaneously exert pressure on the vehicle control ring on the testing platform.

[0016] When the vehicle control ring is squeezed by the first and second squeezing blocks, the pressure spring on the testing platform is simultaneously squeezed by the vehicle control ring. When the pressure spring is under downward force inside the measuring disc, the pressure spring can be directly observed through the scale on the measuring disc to record the vehicle's pressure resistance data.
