Description

Auxiliary equipment for processing and dimension detection of plates

Technical Field

The invention relates to the technical field of sample processing, in particular to auxiliary equipment for processing and detecting the size of a large and medium-sized plate.

Background

In the prior art, in the process of preparing the plate sample, because the sample is too large (for example, the length of the sample is more than 2 meters), the dimensional accuracy of manual sample preparation (drilling, positioning and the like) cannot be ensured (more than one meter, a tape or a ruler is used for measuring the dimensional positioning, the measuring tolerance of the tape or the ruler is large, and errors easily occur in manual measurement), and the sample must be sent to numerical control equipment for processing. There is a problem that many design companies do not have a numerical control machining device, so if you want to make a slightly larger sample, you want to finish the following steps, 1 find a factory with a numerical control machining device, 2 send the sample to the factory, 3 factory create a tool path according to the 2D map, 4 numerical control machine tool, 5 finally take the sample back. The time required in this process is at least one working day, and if there are more orders from the factory, more than one working day is normal, which causes a significant loss in time for the design company. The inventor always thinks that there is a quicker, more convenient and effective processing method, if the graph in CAD is projected onto the plate according to the size of 1:1, the accuracy of the size is guaranteed, the plate and the projector are fixed, and then scribing marks are carried out according to the projection on the plate for processing, so that the sample can be processed by using a few simple tools. There is a corresponding reduction in both time, equipment requirements and personnel requirements. If the function is used in reverse, the sample is processed, whether the sample is qualified or not is detected, the graph in CAD can be projected onto the plate according to the size of 1:1, so that whether the sample is processed is detected to be qualified or not, which is equivalent to a secondary image measuring instrument, but the secondary image measuring instrument can only measure some small parts, and once the size is out of range, the measurement cannot be carried out.
