Positioning fine adjustment device for hole position degree measurement

Abstract

The invention relates to a positioning fine adjustment device for hole position degree measurement. The device is arranged on the bottom plate of a hole position degree measurement tool, and comprisesa base, a fixing frame and a locking cover plate which are arranged on the bottom plate of the hole position degree measurement tool sequentially from bottom to top, wherein the fixing frame is internally provided with a positioning mechanism; the positioning mechanism passes through the locking cover plate along a vertical direction; the fixing frame is provided with a pair of mutually-verticalfine adjustment claw adjustment mechanisms in transmission connection with the positioning mechanism; and the two fine adjustment claw adjustment mechanisms adjust the position of the positioning mechanism in an X-axis direction and a Y-axis direction respectively. In comparison with the prior art, positioning fine adjustment can be completed on a three-coordinate measuring instrument through one-time adjustment, multiple changes of a gasket number and multiple times of processing on gasket thicknesses in a gasket increasing and decreasing fine adjustment mode are avoided, the hole position degree measurement tool processing process is thus simplified, the processing efficiency and the precision are improved, the universality is good, the operation is easy, and the production cost and themanual cost are low.

Description

technical field [0001] The invention belongs to the technical field of detection of sheet metal parts, and relates to a positioning fine-tuning device for hole position measurement. Background technique [0002] Sheet metal is a comprehensive cold working process for thin metal plates (usually below 6mm), including shearing, punching / cutting / compositing, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its distinctive feature is the same Part thickness is consistent. Products processed by sheet metal technology are called sheet metal parts. There are often multiple holes on the sheet metal parts, and the measurement of the hole position usually uses measuring equipment such as three-dimensional coordinates, projectors, and video instruments. Although the measurement accuracy is high and the measurement data can be read directly, in industrial mass production, Sometimes it is only necessary to determine whether the hole position is within the st...

Problems solved by technology

However, it is inconvenient to manufacture the hole position measurement tool by this method, and the measurement tool needs to be repeatedly processed and adjusted, the processing efficiency is low, and there are high requirements for the ability and experience of the operator, and the measurement tool is specially designed. The hole position measurement tool for this product cannot be used for the measurement of other products, which increases the testing cost of the product
