Internal dimension detection device and PLC program control method thereof

Abstract

The invention discloses an internal dimension detection device and a PLC program control method thereof, and relates to the technical field of internal dimension detection equipment, and the technical scheme is that the internal dimension detection device comprises a machine body, a jig fine adjustment device is fixedly installed on the top of the machine body, the jig fine adjustment device comprises a fixing plate, and a pressing detection module is fixedly installed on the outer wall of the right side of the fixing plate; the top of the machine body is fixedly provided with a control assembly, the control assembly comprises a supporting frame, the outer wall of the front end of the supporting frame is fixedly provided with a go-no go gauge detection module, the go-no go gauge detection module comprises a second module base, and the outer wall of the second module base is fixedly connected with the outer wall of the front end of the supporting frame. According to the invention, the pressing detection module and the go-no go gauge detection module are matched for use, so that when the internal size of a product is detected, whether the internal size of the product meets a standard parameter can be accurately identified by identifying the pressure change of the go-no go gauge when the go-no go gauge moves in the product, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of internal dimension detection equipment, in particular to an internal dimension detection device and a PLC program control method thereof. Background technique [0002] In the production of mechanical workpieces, usually when the internal cavity is a special-shaped structure, it is necessary to prepare the measurement of the internal cavity of the part, so as to determine whether the produced part meets the size required for production. [0003] The existing technology has the following shortcomings: the existing measurement method generally enters the cavity through a mechanical arm for measurement, but large errors are prone to occur in the overall operation. Fine, so as to meet the needs of the use of the workpiece, the existing measurement method is not high precision, inconvenient to use. [0004] Therefore, it is necessary to invent an internal dimension detection device and a PLC program control me...
