Rotating telescopic vehicle measuring apparatus

Abstract

The invention relates to a rotating and telescopic automobile measuring instrument, which comprises a measuring head part, a rotating measuring part, a telescopic measuring part and a base part. The measuring head of the measuring head part is connected with an encoder through a shaft; the measuring head part is connected with the rotating measuring part, The rotating measuring part is connected with the telescopic measuring part, and the telescopic measuring part is arranged on the base part. The present invention adopts a telescopic arm structure, and the length of the telescopic arm can be stretched and changed according to the needs of the measurement. Requirements for the length of the measuring arm in the measurement; the measuring head adopts an orthogonal two-axis structure, the measuring head can rotate freely in the two-dimensional space, and the point to be measured can be measured without changing the measuring head. The advantages of the combination of the telescopic arm and the rotating arm are that the measurement process is simplified, the measurement accuracy is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a car space measuring device, in particular to a car measuring instrument capable of rotating and stretching. Background technique [0002] At present, in automobile protection equipment, the equipment used for automobile space measurement, such as the equipment for measuring the coordinates of space points and the distance between two points, all adopt the joint arm type measurement structure. The measurement arm is made of light metal materials, such as aluminum alloy, To provide the requirements for measuring the upper length, encoders are installed between the measuring arms, that is, at the joints, to measure the angle of rotation of the measuring arms. In this way, each measuring arm rotates around its joints to drive the measuring head to the position of the desired measuring point, send a signal to the computer, and the special software will calculate its coordinate value, and then perform geometric calculations between...

Problems solved by technology

However, this kind of measuring equipment has the problem that if the measurement range is large, the length of the measuring arm is not enough. Their method is to remove the original measuring arm and replace it with a longer one during the measurement. The parameters also need to be reset, which is inconvenient; or a slide rail is added, and a measuring ruler is installed on the slide rail, and the slide rail is fixed on the automobile sheet metal correction platform or a movable support frame (the object of our comparison), and the entire measurement The sensor part of the sensor moves on the slide rail to reach the required measurement position, so the slide rail, measuring ruler and support frame are very long, and structurally they are separated from the control computing main cabinet, so they are flexible Sex and economy are worth considering
