Installation hole detection device

Abstract

The invention relates to a detection device, in particular to an installation hole detection device which is used for detecting an installation hole of a detected piece in the production and detection process. The installation hole detection device comprises a base with a reference hole, and a detection part with a socket-connecting hole, wherein the axis of the socket-connecting hole is overlapped with the axis of the reference hole. The installation hole detection device additionally comprises a detection pin which can be inserted into the installation hole of the detected piece and the socket-connecting hole, and a zero calibration pin which can be simultaneously inserted into the socket-connecting hole and the reference hole. The detection part is connected onto the base through a sliding component and can freely slide in the horizontal direction. A measuring mechanism which can measure offset of the socket-connecting hole relative to the reference hole in the horizontal direction and can display the measured offset is arranged on the sliding component. The offset of the installation hole in a first measuring direction and a second measuring direction can be measured through the measuring mechanism. The zero calibration of the measuring mechanism is realized through the zero calibration pin. The installation hole detection device has the advantages that the structure is simple and easy to realize, the cost is low and the measurement of the offset of the installation hole can be accurately realized.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for a mounting hole which detects a mounting hole of a detected part during a production detection process. Background technique [0002] In the process of production inspection, it is often necessary to inspect the position of the installation hole of the inspected part, so as not to fail to assemble. The current technology uses the detection pin to be inserted into the mounting hole of the detected part and the insertion hole of a fixed detection part at the same time for detection. If the detection pin can be inserted smoothly at the same time, it means that the position of the mounting hole is qualified. However, this This detection method cannot quantitatively determine the actual offset between the position of the mounting hole and its theoretical position, and cannot provide technical personnel with reference data for improving production quality. It is necessary t...

The current technology uses the detection pin to be inserted into the mounting hole of the detected part and the insertion hole of a fixed detection part at the same time for detection. If the detection pin can be inserted smoothly at the same time, it means that the position of the mounting hole is qualified. However, this This detection method cannot quantitatively determine the actual offset between the position of the mounting hole and its theoretical position, and cannot provide technical personnel with reference data for improving production quality. It is necessary to use additional expensive equipment such as a coordinate measuring machine for quantitative measurement, resulting in cost increase
