Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1-3, the present application provides a multi-compatible air tightness detection device of a numerically controlled lathe, which comprises a cover plate 1, a distribution plate 2, three extending parts 201, a guide pipe 3, a base 4 and a detection head 5; the cover plate 1 is used for connecting the chuck 8 and is coaxially arranged with the chuck 8; the distribution plate 2 is arranged on the side of the cover plate 1 away from the chuck 8, and a diversion space is arranged in the distribution plate 2 and used for inputting compressed air; three extension parts 201 are uniformly distributed on the peripheral surface of the distribution plate 2, and the three extension parts 201 are respectively communicated with the diversion space; one end of the catheter 3 is slidingly extended into the extension 201; the base 4 is connected to the other end of the guide pipe 3, and a diversion channel is arranged on the base 4 so that compressed air flows from the diversion space to the diversion channel; the detection head 5 is arranged on the side surface of the base 4 far away from the chuck 8, and a detection channel parallel to the axis of the chuck 8 is penetrated and arranged on the detection head 5.
In this application, in order to make things convenient for the dismouting between pipe 3 and the base 4, the face that pipe 3 and base 4 butt joint is the flange face, the cover is equipped with pinch-off strip 6 on the pipe 3, pinch-off strip 6 cladding flange face is connected with base 4 through the bolt.
