Description

Gantry image measuring instrument capable of reducing maintenance frequency

Technical Field

The utility model relates to the technical field of gantry image measuring instruments, in particular to a gantry image measuring instrument capable of reducing maintenance frequency.

Background

The image measuring instrument is based on CCD digital image and is produced by means of computer screen measuring technology and powerful software capacity of space geometric operation. The CCD camera of part of the image measuring instrument is arranged on a portal frame, so that the CCD camera can be applied to image measurement of large products, and the image measuring instrument is also called a portal image measuring instrument.

At present, in order to avoid the situation that the sheet workpiece is warped and shifted when the image measurement is performed on a large sheet workpiece, the Chinese utility model 'a gantry type image measuring instrument' with patent number 202222322400.7 discloses a workbench 4 which can be turned up in a rotating manner in the specification and the drawing, and after a product is placed below the workbench 4, the workbench 4 is pushed by an electric push rod at the side edge of the workbench 4 so that the workbench 4 compresses and flattens the product, and the workbench 4 is transparent and has no chromatic aberration, so that imaging of the product is not influenced when the image measurement is performed on the main body of the measuring instrument, and the effect of improving the measuring precision of the product is achieved.

However, since the workbench 4 is turned up and opened or turned down and flattened in a rotating manner under the pushing of the electric push rod, after a period of use, the gap is increased due to excessive rotation abrasion at the rotating position of the workbench 4, and although the front end of the workbench 4 can be pulled by the electric push rod to flatten a product better, the rear end (rotating position) of the workbench 4 is easy to loose due to the abrasion gap increase, so that the rear end of the workbench 4 is compressed and flattened after a period of use. The existing solution is to replace the rotating shaft and the shaft seat at the rotating position together, although the problem of poor compacting effect can be solved, the replacement is obviously a complex process, and is not dared to be carried out by production staff without maintenance experience, the maintenance waiting and the maintenance process are both time-consuming processes, and in the condition that the looseness of the rear end of the workbench 4 is not particularly obvious, the abrasion gap is difficult to evaluate, at the moment, the difficulty of whether the replacement is carried out or not can also occur, the frequent replacement obviously increases the cost, but the overlong time interval of the replacement can lead to the reduction of the measurement precision.
