Description

Technical Field

[0001] The invention relates to the technical field of brake testing, in particular to a testing device for automobile chassis brakes. Background Art

[0002] In the automotive manufacturing industry, the performance and quality of chassis brakes are directly related to the safety and reliability of the entire vehicle. Therefore, brakes must undergo rigorous testing during the production process, including circumference and flatness tests, to ensure they meet design requirements. Traditional testing methods typically rely on manual operation or semi-automated equipment, which suffers from low efficiency, unstable test accuracy, and high labor intensity. Some existing testing devices use a simple clamping mechanism to secure the brake and perform testing via a rotating or moving probe. However, these devices often suffer from the following drawbacks: Traditional loading methods rely on manual handling or a single robotic arm, making continuous and efficient automated loading difficult, impacting overall testing efficiency. Most devices can only perform a single test (such as circumference or flatness), requiring multiple clamping or equipment changes, increasing operational complexity. Post-test unloading and sorting still require manual intervention, making full automation difficult. To address these issues, there is an urgent need to design an efficient, stable, and functionally integrated automotive chassis brake testing device to improve testing efficiency and accuracy while reducing labor costs. Summary of the Invention

[0003] In response to the above technical problems, the present invention adopts the following technical solutions: a testing device for automobile chassis brakes, comprising a loading mechanism for transferring chassis brakes, the loading mechanism comprising a base plate, the loading mechanism being provided with a clamping mechanism for clamping the chassis brakes and a testing mechanism for performing circumference and flatness tests on the chassis brakes;

[0004] The feeding mechanism comprises a placing table fixedly mounted on a bottom plate, a rotating arm rotatably mounted on the bottom plate, and a lower pressing plate provided on the rotating arm;

[0005] The clamping mechanism comprises a rotating drum rotatably mounted on the placement table, and a clamping disc is fixedly mounted on the rotating drum.

[0006] Furthermore, the feeding mechanism also includes a feeding motor fixedly mounted on the placement table, an eccentric disk is fixedly mounted on the motor shaft of the feeding motor, an eccentric rotating rod is eccentrically mounted on the eccentric disk, an eccentric wheel is fixedly mounted on the rotating arm, and the eccentric wheel and the eccentric rotating rod are rotatably mounted.

[0007] Furthermore, a fixed wheel is rotatably mounted on the rotating arm, a fixed clamp is fixedly mounted on the fixed wheel, the fixed clamp is fixedly mounted to the base plate, an upper rotating wheel is rotatably mounted on the rotating arm, and a transmission belt is wrapped around the upper rotating wheel and the fixed wheel.

[0008] Furthermore, an input rack is fixedly mounted on the base plate, an input belt is provided on the input rack, and a motor for driving the input belt to move is provided on the input rack.

[0009] Furthermore, a movable column is fixedly installed on the upper rotating wheel, a suction cup frame is fixedly installed on the movable column, four suction cups are fixedly installed on the suction cup frame, the suction cup frame has a hollow structure, an air vent is provided on the suction cup frame, the air vent is connected to an external air pump, and the air vent is connected to the suction cup through the suction cup frame.

[0010] The chassis brake is continuously placed on the input belt, and the motor on the input frame drives the input belt to rotate to transport the chassis brake. The loading motor drives the eccentric disk to rotate, and the eccentric wheel and the rotating arm are driven to swing back and forth through the eccentric rotating rod, so that the loading motor continuously rotates to drive the rotating arm to swing back and forth. When the rotating arm swings back and forth, the fixed wheel cannot rotate, and the rotating arm rotates, and the fixed wheel and the rotating arm rotate relative to each other. Under the action of the transmission belt, the upper rotating wheel and the moving column are driven to rotate, so that during the swinging process of the rotating arm, the moving column is always in a vertical state, which is convenient for taking the chassis brake. When the moving column brings the suction cup to the top of the chassis brake on the input belt, the air pump on the vent draws air, and the chassis brake is sucked by the suction cup. Then the rotating arm swings and brings the chassis brake to the clamping disk through the suction cup.

[0011] Furthermore, the clamping mechanism also includes three clamping blocks slidably mounted in the clamping plate, and a clamping block spring is provided between the clamping blocks and the clamping plate.

[0012] Furthermore, a lower pressure column is slidably installed in the placement table, an inner plate is fixedly installed on the lower pressure column, a support rod is fixedly installed on the inner plate, an outer top cone surface is provided on the support rod, the support rod is located in the rotating cylinder, a lower pressure spring is provided between the lower pressure column and the placement table, an upper pressure plate is slidably installed in the lower pressure column, and an inward spring is provided between the upper pressure plate and the lower pressure column.

[0013] When the upper pressure plate and the lower pressure column are not pressed down, the outer top cone surface pushes the three clamping blocks outwards, the clamping block spring is compressed, and the chassis brake is supported from the inside to the outside through the clamping block. When the rotating arm transfers the chassis brake to the clamping disk through the suction cup, the upper pressure plate is pressed down by the lower pressure plate. The elastic force of the inward spring is greater than the elastic force of the downward pressure spring. The downward pressure of the upper pressure plate drives the lower pressure column, the inner plate and the support rod to descend. The downward pressure spring is compressed, the support rod and the outer top cone surface descend, and the clamping block spring rebounds, causing the three clamping blocks to move inward. As the rotating arm continues to rotate, the upper pressure plate continues to descend, the upper pressure plate slides relative to the lower pressure column, the inner plate is compressed, and then the suction cup places the chassis brake on the clamping plate, the suction cup releases the clamping of the chassis brake, and then the clamping plate drives the suction cup to rise. When the lower pressure plate leaves the upper pressure plate, the lower pressure spring rebounds, driving the support rod to rise, and the three clamping blocks are pushed outward through the outer top cone surface. The clamping block spring is compressed, and the chassis brake is clamped from the inside out by the three clamping blocks, completing the placement of the chassis brake.

[0014] Furthermore, the testing mechanism includes a rotating motor fixedly installed in the placement table, which drives the rotating drum to rotate through a rotating transmission belt. A detection motor is fixedly installed on the placement table, a detection screw is fixedly installed on the motor shaft of the detection motor, a detection frame is slidably installed on the placement table, the detection frame and the detection screw form a threaded transmission, an upper probe and a lower probe are fixedly installed on the detection frame, and an eddy current detector is fixedly installed on the placement table.

[0015] Furthermore, the placing table is fixedly installed with an ejection electric cylinder, an electric cylinder is arranged inside the placing table, a lifting slide is fixedly installed on the output end of the electric cylinder, an ejection rack is slidably installed on the lifting slide, an ejection column is fixedly installed on the ejection rack, an ejection plate is fixedly installed on the output end of the ejection electric cylinder, a vertical groove is arranged on the ejection plate, and the ejection column slides in the vertical groove of the ejection plate.

[0016] Furthermore, an output rack is fixedly mounted on the placement table, an output belt is provided on the output rack, and a motor for driving the output belt to move is provided on the output rack.

[0017] The rotating motor drives the rotating drum and the clamping plate to rotate by rotating the transmission belt, thereby driving the chassis brake to rotate through the clamping block, and performing circumferential testing on the chassis brake through the eddy current detector. The rotation of the detection motor drives the detection screw to rotate, thereby driving the detection frame to slide along the placement table, and performing flatness testing on the upper and lower surfaces of the chassis brake through the upper and lower probes. After the test is completed, the push-out electric cylinder extends, and drives the push-out column to slide along the push-out frame through the push-out plate, so that the push-out frame contacts the chassis brake, and then the cylinder in the placement table extends, driving the lifting slide to rise, and the lifting slide drives the push-out frame to rise, and the push-out frame drives the chassis brake to rise, so that the lower surface of the chassis brake is higher than the clamping plate, and the push-out column slides upward along the vertical groove of the push-out plate, and then the push-out electric cylinder continues to extend, and the tested chassis brake is pushed to the output belt through the push-out frame, and the motor on the output frame drives the output belt to rotate to send out the tested chassis brake.

When the rotating arm 108 swings back and forth, the fixed wheel 109 cannot rotate, and the rotating arm 108 rotates, and the fixed wheel 109 cannot rotate. The fixed wheel 109 and the rotating arm 108 rotate relative to each other, and the upper rotating wheel 111 and the movable column 114 are driven to rotate under the action of the transmission belt 112, so that during the swinging process of the rotating arm 108, the movable column 114 is always in a vertical state, which is convenient for taking the chassis brake 4.

The lower pressure spring 202 is compressed, the support rod 206 and the outer top cone surface 211 descend, and the clamping block spring 210 rebounds, causing the three clamping blocks 209 to move inward. As the rotating arm 1 08 continues to rotate, the upper pressure plate 204 continues to descend, the upper pressure plate 204 slides relative to the lower pressure column 201, the inner plate 203 is compressed, and then the suction cup 116 places the chassis brake 4 on the clamping plate 208, the suction cup 116 releases the clamping of the chassis brake 4, and then the clamping plate 208 drives the suction cup 116 to rise. When the lower pressure plate 113 leaves the upper pressure plate 204, the lower pressure spring 202 rebounds, driving the support rod 206 to rise, and the three clamping blocks 209 are pushed outward through the outer top cone surface 211.
