Detailed Description
The principles and features of the present application are described below with reference to the drawings, the examples are illustrated for the purpose of explanation only and are not intended to limit the scope of the present application.
The embodiment of the application discloses an airtight block structure.
Referring to fig. 1-2, an airtight block structure comprises a shell 1, a cushion block 2 and a piston 3, wherein a cavity 4 is formed in the shell 1, the cushion block 2 is connected with one end of the shell 1, and the piston 3 is positioned at the other end of the shell 1 and is movably connected with the cavity 4; an air inlet 5 is formed in the cushion block 2, an air outlet 6 is formed in the side wall of the shell 1, when the brake disc 10 is not installed in place, the air outlet 6 is communicated with the cavity 4, when the brake disc 10 is installed in place, the piston 3 isolates the air outlet 6 from the cavity 4, and a sealing plug 9 is arranged at the end part, far away from the cavity 4, of the air outlet 6.
When the brake disc 10 is processed and produced, an operator installs the airtight block on the clamp, then clamps the brake disc 10 on the clamp, at the moment, the airtight block detects the installation position of the brake disc 10, and the airtight block is matched with the piston 3 through the fixed shell 1 to realize the function of positioning the brake disc 10.
When the brake disc 10 is completely attached to the fixed shell 1 and the piston 3, the brake disc 10 is indicated to be installed in place, and the next processing operation can be performed; at this time, an air source enters from the air inlet 5, enters the positions of the shell 1 and the piston 3 along the air path, when the brake disc 10 is installed in place, the piston 3 blocks the air outlet 6, air cannot leak outwards, when the brake disc 10 is not put well, the piston 3 does not block the air outlet 6, air leaks at a gap between the shell 1 and the piston 3, the monitoring function of the installation position of the brake disc 10 is realized by monitoring the air leakage condition of the gap between the shell 1 and the piston 3, and an O-shaped ring structure is cancelled, so that fine dust is not easy to cause adverse effects on the normal operation of an airtight block.
The casing 1 is connected with alarm module, and alarm module is used for detecting the gas tightness between casing 1 and the piston 3, and when there is gas leakage in the gap department between casing 1 and the piston 3, the position of explanation brake disc 10 has been placed by mistake, and alarm module generates alarm signal and reports to the police this moment, and suggestion operating personnel adjusts brake disc 10 position, and alarm module can be more accurate whether the detection brake disc 10 is installed and is taken one's place, in this application embodiment, alarm module carries out alarm operation through proximity switch.
