Clamp for testing durability of calipers

The invention relates to the technical field of brake detection, in particular to a caliper durability test fixture. The invention discloses a caliper durability test fixture, which comprises a first power transmission assembly, a second power transmission assembly, a fatigue test device and a force sensor which are sequentially arranged and connected along a vertical upward direction, and is characterized in that the fatigue test device is used for being repeatedly clamped by a caliper; the force sensor is used for testing the clamping force value of the calipers; the first power transmission assembly drives the fatigue testing device and the force sensor to reciprocate in the vertical direction through the second power transmission assembly. In the invention, when a force sensor is located between two discs of the calipers, the two discs of the calipers are close to each other and clamp the force sensor, and the force sensor measures a specific numerical value of the braking force of the calipers and transm
