Embodiment
Contrast accompanying drawing below, by the description to embodiment, be described in further detail the specific embodiment of the present invention, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present invention, technical scheme, and contribute to its enforcement.
As shown in Figures 1 to 4, a kind of automobile brake master cylinder cylinder bolt of the present invention hole location tolerance detection device, two test rods paralleled comprising detection platform 1 and be located in detection platform 1, two test rods are respectively the first test rod 3 and the second test rod 4, detection platform 1 is provided with the pilot hole 11 for locating automobile brake master cylinder cylinder body 6, two test rods are distributed in the both sides of pilot hole 11, and the distance wherein between a test rod and pilot hole 11 center of circle is greater than the distance between another test rod and pilot hole 11 center of circle.
Specifically, as depicted in figs. 1 and 2, detection platform 1 is rectangular block shape structure, when detecting, automobile brake master cylinder cylinder body 6 is placed on the end face of detection platform 1, installed surface due to the bolt hole place of automobile brake master cylinder cylinder body 6 also has a boss protruded, this boss size is greater than the interface size of automobile brake master cylinder cylinder body 6 end, in order to this boss can be held, detection platform 1 end face on be provided with the holding tank 13 of a rectangle, this holding tank 13 is extend to another side along the Width of detection platform 1 from a side, and the degree of depth of this holding tank 13 is at least equal with the thickness of boss, guarantee to hold boss, the installed surface of automobile brake master cylinder cylinder body 6 is contacted completely with the end face of detection platform 1.
As shown in Figure 2, pilot hole 11 is located on the bottom surface of holding tank 13, and be through to the bottom surface of detection platform 1, the diameter of pilot hole 11 and the interface circumscribed circle diameter sizableness of automobile brake master cylinder cylinder body 6, guarantee to hold the interface of automobile brake master cylinder cylinder body 6.
As shown in Figure 2, first test rod 3 and the second test rod 4 stretch out from the holding tank 13 of detection platform 1, be provided with two circular mounting hole 12, two mounting holes 12 in the bottom surface of holding tank 13 and be through to the bottom surface of detection platform 1, the axis of two mounting holes 12 parallels with the axis of pilot hole 11.The end of the first test rod 3 and the second test rod 4 is inserted in a mounting hole 12 respectively, realize the installation in detection platform 1, and the distance between the center of circle of the first test rod 3 and the center of circle of pilot hole 11 is greater than the distance between the center of circle of the second test rod 4 and the center of circle of pilot hole 11.In addition, the angle between the line in the center of circle of the first test rod 3 and the center of circle of pilot hole 11 and the line in the center of circle of the second test rod 4 and the center of circle of pilot hole 11 is less than 180 degree, and namely two test rods are asymmetric arrangement in the outside of pilot hole 11.
