Brake caliper hook head verticality measurement check tool

Abstract

The invention discloses a brake caliper hook head verticality measurement check tool. The check tool comprises a positioning seat, an actuating rod which is movably sleeved with the inner hole of thepositioning seat; the head of the positioning seat is provided with a positioning head inserted into the cylinder hole of a brake caliper; a movement hole which radially extends is formed in the positioning head; a sliding inclined block is disposed in the movement hole; the sliding inclined block is detachably connected with a pressing head; an inclined face hole is formed in the sliding inclinedblock; and the actuating rod is provided with an actuating portion that acts on the inclined face of the inclined face hole so as to make the sliding oblique block slide radially along the movement hole. According to the brake caliper hook head verticality measurement check tool of the invention, the cylinder hole of the brake caliper is positioned through adopting an internal expansion clampingmode; and the pressing head which is convenient to replace is adopted so as to adapt to the measurement of brake calipers with different cylinder diameters, and therefore, the problems of failure to realize universality, numerous specifications and inconvenience in management of special check tools for the verticality measurement of the hook heads of brake calipers with different cylinder diameters can be solved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a measuring tool for measuring the perpendicularity of a hook head of a brake caliper. Background technique [0002] Brake calipers are an important part of automotive hydraulic disc brakes. In order to meet the needs of different models, there are many varieties and specifications, and the bore diameters of brake calipers are different. There are many important features on brake calipers that affect braking performance. Process monitoring is required. like figure 1 As shown, the verticality of the brake caliper hook end surface 61 relative to the cylinder hole 62 is one of the important characteristics that need to be monitored during the machining process. At present, in order to detect this characteristic, special inspection tools for the verticality of the hook head of the caliper body of various specifications have been designed and manufactured. However, with the expan...
