The fixing pipe is inserted through the fixing plate and has a fixing thread formed on an outer circumferential surface thereof, and is coupled to the fixing plate by tightening coupling of a pair of upper and lower nuts.
The sliding pipe is formed with a large diameter peripheral portion on an upper outer circumferential surface so as to be in close contact with a circumferential inner circumferential portion of the fixed pipe, Shaped outer circumferential surface is formed on the lower outer circumferential surface so as to be in close contact with the inner circumferential surface of the lower end of the outer circumferential surface.
The spring has a smaller diameter than the outer periphery of the sliding pipe and has a lower end supported by the upper end of the outer periphery of the sliding pipe and a lower end supported by the inner periphery of the fixed pipe, And is inserted into the outer peripheral portion.
The present invention further includes a pair of bushings coupled to the upper and lower inner circumferential surfaces of the fixed pipe in a ring shape and in contact with the outer circumferential surface of the sliding pipe.
The bushing is made of polytetrafluoroethylene (PTFE), and is press-fitted to the upper and lower inner circumferential surfaces of the fixed pipe.
The sliding pipe is formed with upper and lower threads at the upper and lower ends, respectively. The vacuum connector is screwed into the upper thread of the sliding pipe. The water pipe is screwed into the lower thread of the sliding pipe .
The sliding pipe may further include a pad connecting hole which is in close contact with the lower surface of the water receiver and is screwed to a lower portion of the sliding pipe so that the water receiving portion is positioned and communicated with the inside of the sliding pipe. do.
In addition, the water receptacle may include a cup-shaped lower face portion in a cup shape and an annular peripheral portion protruding upward along the periphery of the lower face portion.
The vacuum adsorption apparatus according to the present invention is characterized in that the water receiving part is provided between the sliding pipe and the adsorption pad so as to receive foreign matter generated by contact friction between the fixed pipe and the sliding pipe so that the foreign matter directly adheres to the adsorption pad or the workpiece So that it is possible to improve the quality and productivity and to easily separate only the waterbath, so that it is easy to clean and remove the foreign matter.
In addition, a bushing made of polytetrafluoroethylene (PTFE) with a low coefficient of friction with a smooth surface on the contact friction surface between the fixed pipe and the sliding pipe is installed to drastically reduce the foreign matter generated between the fixed pipe and the sliding pipe have.
