Mechanical part hole pitch tolerance measuring test tool convenient to use

Abstract

The invention discloses a mechanical part hole pitch tolerance measuring test tool convenient to use. The mechanical part hole pitch tolerance measuring test tool comprises a positioning plate. A sliding groove is formed in the upper surface of the positioning plate. A sliding block is arranged inside the sliding groove. A brake switch is arranged on the sliding block. One end of the brake switch extends into a strip-shaped through hole formed in the front face of the positioning plate. A dial gauge is arranged on the lower side of the strip-shaped through hole. A sliding detection column is arranged on the sliding block. A fixed detection column is arranged on one side of the sliding groove. A handle is arranged in the middle of the lower surface of the positioning plate. The mechanical part hole pitch tolerance measuring test tool convenient to use is convenient to operate, high in measuring efficiency, good in adaptability to the distance between two holes in various to-be-detected components, and capable of conveniently detecting whether the tolerance of holes in various to-be-detected components is qualified or not, workers can complete overall self-inspection at any time, and the production efficiency and the production quality are improved.

Description

technical field [0001] The invention relates to the technical field of inspection tools for mechanical parts, in particular to an easy-to-use inspection tool for measuring hole distance tolerances of mechanical parts. Background technique [0002] At present, mechanical processing and manufacturing are developing in the direction of batching and large-scale. The detection hole distance is not uncommon in the manufacturing of mechanical parts. In production, if the vernier caliper is used to manually detect the workpiece, the production efficiency will be greatly reduced. And the quality The inspector cannot guarantee the inspection of each workpiece, so the production quality cannot be guaranteed. How to adopt high-efficiency and practical special inspection tools for detection distance is an important way to improve production efficiency. Reasonable special inspection tools can greatly reduce the auxiliary time of the process and improve the production cycle of the assembly...

Problems solved by technology

[0003] A hole distance tolerance measuring tool for mechanical parts disclosed in the Chinese Invention Patent Application Publication No. CN203116673U is characterized in that it includes a positioning plate, and the two ends of the positioning plate are provided with a detection device with the same spacing as the distance between the two holes of the workpiece to be measured. column, and a handle is set in the middle of the positioning plate, but the measuring tool cannot adjust the distance between the detection columns, and can only measure two holes on the workpiece to be measured with a fixed distance. If the hole spacing changes, it is necessary to replace the measuring gage with the same spacing between the two detection columns as the two holes on the workpiece to be measured, which makes it extremely inconvenient to use
