Abstract

The invention relates to a brake shoe external arc surface accuracy measuring instrument for automobile brakes. The brake shoe external arc surface accuracy measuring instrument comprises a base body part, a measuring mechanism and a workpiece positioning mechanism; three support pins, distributed along the inner edge of the arc periphery of an upright plate of the base body part, are arranged on the upright plate of the base body part; the sliding seat bushing of the measuring mechanism sleeves a guide rod; a sliding seat sleeves the sliding seat bushing; the sliding seat is sleeved with a meter stand; the meter stand is provided with a dial indicator; the dial indicator can synchronously rotate or move axially with the sliding seat; an axial positioning sleeve sleeves the guide rod; the guide rod is mounted on a guide rod tail seat and a guide rod front seat; the positioning rod supporting seats of the workpiece positioning mechanism are provided with workpiece positioning rods; and a bottom plate is provided with a sliding seat limiting rod which limits the axial movement of the sliding seat when the sliding seat rotates, and limits the rotation of the sliding seat when the sliding seat axially slides. With the brake shoe external arc surface accuracy measuring instrument adopted, the use condition of a brake shoe on an automobile can be simulated; and the circularity of the outer arc surface of a brake shoe panel (M) and the axial straightness of the brake shoe panel (M) can be measured conveniently and accurately.

Description

technical field [0001] The invention relates to a measuring facility for automobile brakes, in particular to a detection instrument for brake shoes. Background technique [0002] With the development of science and technology and the continuous improvement of road quality, the driving speed of cars is getting faster and faster, and the requirements for traffic management and car safety are stricter. The relevant auto parts standards require that the performance and safety of cars must be guaranteed, and auto parts are gradually realized. Specialized production. Automobile brakes are an important part to ensure the safe driving of automobiles. Existing automobile brakes have higher and higher requirements on the machining accuracy and detection accuracy of the outer arc surface of the brake shoes. It is necessary to have special detection instruments with high precision and high efficiency. At present, The special testing instruments used by domestic general auto parts facto...
