Adjusting the clamping block position to fit different brake calipers or to obtain accurate measurement positions makes it difficult to achieve perfect accuracy every time. This introduces significant measurement errors for high-precision brake caliper piston clamping force testing, severely impacting the reliability of the test results. Utility Model Content

[0032] Furthermore, as a preferred embodiment, a locking bolt 17 is provided in the fixing hole, and the fixing seat 2 is connected to the base plate 1 through the locking bolt 17.

[0033] The working principle of this utility model is as follows: In use, the two fixed seats 2 can be moved first to adjust the distance between them, so that the distance between the two fixed seats 2 matches the distance between the two lug holes on the brake caliper 3. Then, the brake caliper 3 is connected to the fixed seats 2 by bolts. After connection, the fixed seats 2 are connected to the base plate 1 by locking bolts 17 to fix the positions of the fixed seats 2 and the brake caliper 3. Then, the base 42 is placed on the base plate 1 and positioned below the brake caliper 3. The adjusting screw 13 is turned on, and the depth of the adjusting screw 13 inserted into the slot is adjusted to control the sliding of the second lower clamping block 7 along the guide rod 12. The distance between the first lower clamping block 6 and the second lower clamping block 7 can be adjusted by sliding the second lower clamping block 7. The adjustment is stopped when the distance between the first lower clamping block 6 and the second lower clamping block 7 matches the opening size of the brake caliper 3. Then, the upper adjusting clamping block 5 is set between the first lower clamping block 6 and the second lower clamping block 7. One end of the push cylinder 41 is abutted against the base 42, and the threaded rod 10 is inserted into the other end of the push cylinder 41. The corresponding control parameters are set on the display screen 15. The control system 14 controls the drive motor 8 to work. The drive motor 8 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the push cylinder 41 to move linearly along the axial direction to push the base 42. The base 42 moves linearly away from the drive motor 8, causing the pressure sensor 11 to move linearly away from the drive motor 8. This movement changes the contact area between the pressure sensor 11 and the piston inside the brake caliper 3, thus changing the clamping force measured by the pressure sensor 11. The pressure sensor 11 sends the detected clamping force data of the brake caliper 3 to the control system 14. Simultaneously, the distance sensor 16 also sends the detected distance traveled by the pusher 41 to the control system 14. After analyzing and processing the received information, the control system 14 can generate a pressure reading on the display screen 15. The relationship curve between clamping force and distance allows staff to intuitively understand the position of pressure sensor 11 when the clamping force is at its maximum by observing the curve on display screen 15. This position is the optimal placement position of pressure sensor 11. This is because the inherent performance of brake caliper 3 remains unchanged during the test, but if the placement position of pressure sensor 11 is slightly off, the measured value may have a large error and cannot truly reflect the actual clamping force of brake caliper 3. Once the optimal position of pressure sensor 11 is determined through testing, this distance data can be directly used to test the clamping force for other brake calipers of the same product on the production line.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
