Description
Technical Field
The utility model belongs to the detection device field of car body material object size development in-process relates to an adjustable open shelves dipperstick device.
Background
In the process of developing the physical stage size of the white automobile body of the automobile, all large subassemblies welded into the automobile body framework are required to be placed in a framework PCF detection tool for describing a cross line, and the integral distance between the left side and the right side of the automobile body framework is recorded by measuring the intersection point of the cross lines described by the left side subassembly and the right side subassembly; and each large framework sub-assembly completing the PCF process can complete welding on the framework welding line, before welding starts, the central point of a left cross line and a right cross line which are previously carved on the PCF checking fixture are measured on the main splicing station fixture of the main welding line of the framework again, so that the purpose of carrying out comparative analysis on the central point and the numerical value measured on the PCF checking fixture is achieved, then the reason for generating the difference is gradually analyzed, and a foundation is laid for the improvement of the subsequent framework size qualified rate. When the central point of the left cross line and the right cross line is seriously staggered, the vernier scale of the traditional vernier measuring scale can only slide and cannot rotate by an angle, the measurement cannot be realized when the measurement task is completed, the limitation of the traditional vernier measuring scale on the shaping of the vehicle body is large, the flexibility degree is low, and the traditional vernier measuring scale cannot adapt to the current vehicle type items with diversified short periods.
Disclosure of Invention
The utility model provides an overcome the above-mentioned problem that prior art exists, provide an adjustable open gear dipperstick device.
The utility model discloses an adopt following technical scheme to realize:
the utility model provides an adjustable open gear dipperstick, a serial communication port, including the shaft-like dipperstick mobile jib of a cylinder and a ruler that has the scale, the rotating base suit that slides of two hollow cylinder sleeve structures is on the dipperstick mobile jib, the rotating base that slides can be on the dipperstick mobile jib back-and-forth movement and rotation, lock nut threaded connection is on the rotating base that slides, lock nut of screwing can fix the rotating base that slides on the dipperstick mobile jib, every rotating base that slides on equal threaded connection have with the shaft line vertically shaft-like measuring head of the rotating base that slides, the tip of measuring head is the toper, dipperstick mobile jib both ends respectively are provided with the spacing end cover of a base that prevents the rotating base that slides from the slide-out on the dipperstick mobile jib, the ruler is used for measuring the actual distance at two most advanced positions.
The further technical scheme is as follows: the both ends of dipperstick mobile jib have the internal thread, and the spacing end cover of base is stepped shaft structure, has the external screw thread on the little journal section of the spacing end cover of base, and the diameter of the big journal section of the spacing end cover of base is greater than the internal diameter of the rotating base that slides, and the spacing end cover of base passes through external screw thread and dipperstick mobile jib tip threaded connection on the little journal section.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the sliding rotary base connected with the measuring head of the utility model can realize the rotary motion on the basis of realizing the sliding motion, and can ensure that the tip part of the measuring head is coincided with the central point of the measured cross line;
2. the measuring head of the utility model can realize flexible splicing, and can replace the conventional measuring head by using the measuring head with a special structure under the condition of more complex structure of the vehicle body, thereby achieving the purpose of measurement;
