An airtight detection device

Abstract

The invention discloses an airtightness detection device, including an air pressure detection device, a gas-guide tube, a detection base and a contact. The detection base is connected with the air pressure detection device through the gas-guide tube, an L-shaped vent hole is arranged in the detection based, and the contact is arranged within a vertical segment of the L-shaped vent hole; a side wall of the contact is provided with a limiting groove, a limiting bolt hole is arranged on the side wall of the detection base, and a limiting bolt is inserted in the limiting groove through the limiting bolt hole; and a sealing ring is mounted at the bottom of the contact. The airtightness detection device provided by the invention is high in detection precision, low in cost and wide in range of application, is of great help to improving machining precision of a product, can greatly improve the percent of pass of products, and is simple to use, and thus can well satisfy market demands.

Description

technical field [0001] The invention relates to an airtight detection device, which is used for detecting whether a workpiece is placed unevenly. Background technique [0002] At present, the existing air-tight detection device can only detect whether the workpiece is clamped or whether there is a workpiece, but for whether the workpiece is clamped and flat, ordinary methods and equipment cannot be used to detect, such as the method of laser equipment detection, because of The cost is too high and it is mostly used on high-end equipment, and the application rate for low-end equipment is extremely low. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide an airtight detection device, which can detect the subtle placement offset of the workpiece. [0004] The object of the present invention is achieved through the following technical solutions: [0005] An air-tight detection device includes an air pressur...
