Clamping force detection tool of brake calipers

The utility model relates to a clamping force detection tool of brake calipers. The clamping force detection tool comprises a platen, four linear shafts 1, two linear shafts 2 and a column plate; the upper ends of the four linear shafts 1 are fixedly connected with the column plate, wherein two linear shafts 1 at the front side are sleeved with linear bearings 1 and linear bearings 2; a pressing mobile plate is arranged between the linear bearings 1; a pressing bar mobile plate is arranged between the linear bearings 2; the pressing mobile plate is symmetrically sleeved with two pull bars; the upper ends of the two pull bars are fixedly connected with the pressing bar mobile plate; the lower ends of the two pull bars are connected with a lifting plate; the middle of the lifting plate is sleeved with a pressing rod; the upper end of the pressing rod is connected with a force sensor; the upper end of the force sensor is connected with a force sensor connecting seat; the force sensor connecting seat is fixed at the lower end surface of the pressing bar mobile plate; and the column plate is provided with a No.1 air cylinder and a No.2 air cylinder. With the clamping force detection tool of the brake calipers of the utility model adopted, the clamping forces of the brake calipers can be rapidly and accurately detected, and the automation of a detection process can be realized, and a detection cycle can be shortened, and clamping force detection efficiency of the brake calipers can be improved.
