Embodiment Construction

[0032] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0033] Such as figure 1 and figure 2 As shown, the vacuum booster nominal diameter measuring instrument includes a measuring rod 1, a claw 4 with two claws and a measuring rod fixture 3. During measurement, the two claws are stuck on the cylindrical surface of the vacuum booster 6, and the claw 4 The distance between the two claws is a fixed value, the upper part of the claw is provided with a measuring reference plane, and in the middle of the measuring reference plane, there is a through hole matching the measuring rod, and the measuring rod can slide in the through hole; beside the through hole There is a threaded hole, and a U-shaped groove is provided on the measuring rod fixture 3, and the measuring rod fixture 3 is fixed on the claw by hand-tightening the bolt I2 through the U-shaped g...

Abstract

The invention discloses a nominal diameter measuring instrument and measuring method for a vacuum booster. The measuring instrument comprises a measuring rod and a clamping jaw provided with two claws, wherein a through hole matched with the measuring rod is formed in the middle of the clamping jaw, and the measuring rod can slide in the through hole. The measuring method comprises the following steps of placing the claws at the two ends of the clamping jaw on the surface of a cylinder of the vacuum booster, enabling the measuring rod to extend downwards to be in contact with the surface of the vacuum booster, screwing a bolt to fix the measuring rod on a measuring rod clamp, dismounting the measuring rod clamp and the measuring rod which are fastened together from the clamping jaw, measuring the distance from the end of the lower portion of the measuring rod to the measuring rod clamp and calculating or looking up a table to obtain the nominal diameter of the vacuum booster. The nominal diameter measuring method can accurately, quickly and nondestructively measure the nominal diameter parameter of the vacuum booster in a state where an automobile is not dismounted.

Description

technical field [0001] The invention relates to the technical field of auto parts measurement, in particular to a vacuum booster nominal diameter measuring instrument and a measuring method. Background technique [0002] When analyzing and researching competing vehicles in a non-disassembled state, it is difficult to measure the vacuum booster with a conventional caliper or tape measure due to the hidden location of the vacuum booster, poor accessibility, and the brake master cylinder blocking the centroid diameter parameter. [0003] At present, it is generally estimated by visual inspection. This method relies heavily on personal experience, and the reliability of the results is low. This parameter plays a decisive role in the matching of the braking system. How to obtain this parameter accurately, quickly and without damage has become an urgent problem to be solved. Contents of the invention [0004] Aiming at the deficiencies of the existing technology, the technical...
