Description

Technical Field

[0002] Brake pads are an important part of the car's braking system. They are located inside the brake disc or drum on the wheel. When the driver presses the brake pedal, the brake pads will squeeze the brake disc or drum tightly, generating friction, thereby slowing down or stopping the rotation of the wheel, and ultimately achieving deceleration or stopping of the entire vehicle.

[0003] Currently, after the brake pads are produced, they need to be subjected to various tests. To determine whether the brake pads can be effectively assembled, the inner curvature and hole position of the brake pads need to be tested. The existing testing method is to open a hole corresponding to the brake pad signal on an adapted roller, place the brake pad on the roller for fitting, and observe whether the inner curvature of the brake pad fits the outer wall of the roller. Multiple pins with the same diameter as the holes on the brake pads are inserted to observe whether the pins can extend into the holes on the roller. The curvature and hole position of the brake pads are tested through the above steps.

[0004] This detection method requires repeatedly inserting and pulling out the pin shaft to detect the hole position of the brake pad.

[0028] like Figure 1 and Figure 3 As shown, the detection roller 3 is provided with a plurality of detection holes 4, the positions of which are provided according to the process, so that the plurality of detection holes 4 under the same process correspond to the positions of the holes on the brake pads, and detection heads 5 are slidably provided in the detection holes 4, and a spring 7 is sleeved on each detection head 5, and the two ends of the plurality of springs 7 are respectively fixedly connected with the corresponding detection holes 4 and the corresponding detection heads 5, and the detection holes 4 on the detection roller 3 are countersunk from the inside to the outside, which can facilitate the connection of the spring 7 and the sliding of the detection head 5 in the detection hole 4. The designed spring 7 can prevent the detection head 5 from extending outward from the detection hole 4 when not in use. The outer wall of the detection roller 3 is also provided with a plurality of warning lines 27, and the design of the warning lines 27 can facilitate personnel to move the contact position between the detection roller 3 and the two driving rollers 25 to between two of the warning lines 27, so as to prevent the detection head 5 from colliding with the driving roller 25.

A plurality of pushing plates 10 are used to abut against one end of a plurality of detection heads 5. Such an arrangement can effectively drive the pushing plate 10 to abut against one end of the detection head 5 by moving the slide bar 9, and push the detection head 5 to slide in the detection hole 4.

[0030] like Figure 1As shown, the mounting plate 8 is provided with a driving member for driving the plurality of slide bars 9 to slide along the plurality of slide grooves 11. The driving member is a driving plate 14, which is fixed on the connecting rod 13 and is coaxial with the mounting plate 8.

When the roller 28 passes through the recess 22, the roller 28 drives the second drive rod 20 and the slide bar 9 to move into the slide groove 11, further drives the retraction of the push plate. The provided roller 28 and track groove 24 can facilitate the movement of the second drive rod 20 on the drive block 18.

[0033] Working principle:

[0034] When in use, first rotate the corresponding detection roller 3 according to the model of the brake pad to be detected, so that the hole position of the corresponding model on the detection roller 3 is between 45° and 60° obliquely upward, which is convenient for personnel to place and take. By fitting the inner arc of the vehicle-related pad with the outer wall of the detection roller 3, observe whether the curvature of the brake pad is qualified; when the detection hole 4 is in position, the connecting rod 13 is driven to rotate by the driving motor 12, and further drives the driving member of any of the above embodiments to rotate, and drives the slide bar 9 to retract in the slide groove 11, and makes the push plate 10 abut against the detection head 5, pushing the detection head 5 to extend out of the detection hole 4. If the brake pad hole position is qualified, the detection head 5 will directly pass through the hole position on the brake pad. If the brake pad hole position has a large deviation, the detection head 5 will abut against the brake pad, and the brake pad will be lifted up. Therefore, the detection is carried out through the above steps. The device has a simple structure and convenient detection, which is conducive to improving the efficiency of brake pad detection.
