Embodiment 1
[0022] see figure 1 , the present embodiment provides a device for measuring the highest point of the automobile wheel eyebrow, including a sliding rheostat 101, a probe 102, a first moving mechanism 103 and a display unit 104; one end of the probe 102 can move along the automobile wheel eyebrow, and the other end is connected to The sliding rheostat 101 is connected, the sliding rheostat 101 is located in the first moving mechanism 103 , and the sliding rheostat 101 can move in a direction perpendicular to its axial direction, and the display unit 104 is connected with the sliding rheostat 101 .
[0023] In this example, see figure 2 , the first moving mechanism 103 includes a spring 1031, the spring 1031 is sleeved outside the sliding rheostat 101, one end of which is connected to the probe 102, and the initial state of the device is that the probe 102 is located at the highest point of the stretched state of the spring 1031. In order to facilitate fixing, a frame can also...
Embodiment 2
[0030] see Figure 4 , the present embodiment provides a method for measuring the highest point of the wheel eyebrow of an automobile, using the device provided in the above device embodiment to measure the wheel eyebrow of the automobile, the method specifically includes:
[0031] Step 201: Determine a point on the wheel eyebrow of the automobile, and make one end of the probe touch the point;
[0032] Step 202: Make the sliding rheostat move in a direction perpendicular to its axial direction, and at the same time, move the other end of the probe along the axial direction of the sliding rheostat under the action of the first moving mechanism, so that one end of the probe moves along the move;
[0033] Specifically, when the above-mentioned device includes a second moving mechanism and the second moving mechanism includes a knob, a gear, and a rack; the knob can be turned to make the knob control the rotation of the gear, and the gear drives the meshing connected rack, so th...

Abstract
The invention discloses a device and a method for measuring a highest point of an automobile wheel arch, belonging to the field of measurement of highest points of automobile wheel arches. The device comprises a slide rheostat, a probe, a first travel mechanism and a display unit, wherein one end of the probe can move along an automobile wheel arch, and the other end is connected with the slide rheostat; the slide rheostat is positioned in the first travel mechanism and can move along a direction axially perpendicular to the slide rheostat; the display unit is connected with the slide rheostat and displays the resistance value of the slide rheostat; the first travel mechanism is used for enabling the probe to move along the axial direction of the slide rheostat when the slide rheostat moves along the direction axially perpendicular to the slide rheostat and simultaneously changing the resistance value of the slide rheostat; and when the resistance value is a limit value, a point corresponding to the probe is the highest point of the automobile wheel arch. The invention can determine the position of the highest point of the automobile wheel arch by moving the probe and recording the numerical value of the display unit and is easy and convenient to operate, and the device has lower cost because parts used for the device have low price.
Description
technical field [0001] The invention relates to the field of measuring the highest point of an automobile wheel eyebrow, in particular to a device and method for measuring the highest point of an automobile wheel eyebrow. Background technique [0002] Automobile wheel eyebrows are the equipment located above the car body and tires. The wheel eyebrows play the role of decorating the body and reducing resistance. The highest point of the wheel arch affects the position of the tire, the stiffness of the suspension and the attitude of the whole vehicle. Therefore, it is particularly important to accurately find out the position of this point. [0003] At present, there are two methods commonly used to determine the highest point of the wheel eyebrow. One is manual measurement, that is, to determine the position of the wheel center with the naked eye, and then use a string or other tools to find a point on the wheel eyebrow vertically, and consider this point to be the wheel cen...
