Abstract
The utility model provides a multi-channel negative pressure rotary joint which comprises a rotary shaft and a fixing sleeve sleeved with the rotary shaft, wherein a plurality of annular air grooves are arranged on the circumferential surface of the rotary shaft; air paths communicated with the annular air grooves are arranged in the rotary shaft; and vent holes correspondingly communicated with the annular air grooves are arranged on the circumferential wall of the fixing sleeve. As a rolling bearing is arranged between the rotary shaft and the fixing sleeve, the rotation flexibility, the reliability and the durability of the rotary joint are increased; meanwhile, the original air flow passing area is changed from phi 3.2 to phi 4.0, and the negative pressure suction is increased; and the operation space can be improved as the plurality of vent holes on the fixing sleeve are reasonably distributed at two sides of the circumferential wall of the fixing sleeve; therefore, compared with the prior art, the multi-channel negative pressure rotary joint has the characteristics of better performance and durability, and is more convenient to operate.
Description
Technical field
The utility model relates to a kind of air pressure swivel joint, particularly a kind of multichannel negative air pressure swivel joint, and it mainly is applicable to the grinding transfer machine in glass edge, the angle vertical lapping machine.
Background technique
At present, in the glass edge of plasma or lcd productive line, angle vertical lapping machine, grind the transfer machine and undertaking the task of adsorb glass and rotating glass, it adsorbs glass finishes by a plurality of negative pressure suckers.When the sucker absorption glass that grinds the transfer machine rotates, negative pressure sucker and then rotates, but for negative pressure sucker provides the gas circuit of negative air pressure can not be with commentaries on classics, so the gas circuit of negative pressure sucker join by a multichannel negative air pressure swivel joint and potential source angrily, to prevent gas circuit along with negative pressure sucker rotates.
Existing multichannel negative air pressure swivel joint mainly comprises a running shaft and a fixed cover that is enclosed within on the running shaft, be provided with a plurality of gas circuits in the running shaft, it joins by the flexible tracheae of flange and each negative pressure sucker, fixed cover is installed on the running shaft by self oiling bearing, and be provided with a plurality of air outlet holes that communicate with a plurality of gas circuits in the running shaft on fixed cover, these a plurality of air outlet holes join by the angrily potential source of fixing gas circuit.When sucker rotated, the driven rotary axle rotated, and fixed cover does not change, thereby finished the task that sucker rotates, gas circuit is not changeed.This rotary joint also exists following deficiency at present:
1, adopt sliding bearing between running shaft and the fixed cover, make action underaction between the two, reliability and durability are not so good.
2, to cross area big inadequately for the air communication of sucker, makes suction poor slightly;
3, a plurality of air outlet holes only are distributed in a side of fixed cover circumferential surface on the fixed cover, make install and the Job Operations of maintenance convenient inadequately.
The model utility content
The purpose of this utility model is at the deficiency that exists in the prior art, and a kind of improved multichannel negative air pressure swivel joint is provided, and makes its performance better, more convenient operation.
For achieving the above object, the technical solution of the utility model is as follows:
It has a running shaft and a fixed cover that is nested with this running shaft, circumferential surface at described running shaft is provided with a plurality of annular gas tanks, in described running shaft, be provided with the corresponding radially air outlet hole that communicates with described annular gas tank with this vertical axial admission hole that communicates of air outlet hole radially, and on the peripheral wall of described fixed cover, be provided with the corresponding air outlet hole that communicates with annular gas tank, be provided with annular seal groove and be located at O-ring seals in this annular seal groove between described a plurality of annular gas tanks, its improvements are: described fixed cover is installed on the running shaft by a pair of rolling bearing.
The further improved technological scheme of the utility model is as follows:
The aperture in described radially air outlet hole and axial admission hole is Φ 4.0.
The axially staggered both sides that are distributed in the fixed cover peripheral wall of a plurality of air outlet holes on the described fixed cover.
By technique scheme as can be seen, the utility model has adopted rolling bearing between running shaft and fixed cover, has increased rotation flexibility, reliability and durability.It is original air communication to be crossed area change Φ 4.0 into from Φ 3.2 that the utility model further improves, and has increased the suction of sucker, simultaneously, a plurality of air outlet holes on the fixed cover reasonably is distributed in the both sides of fixed cover peripheral wall, has improved working space.Therefore, the utility model compared with the prior art, have performance better, the characteristics of more durable, more convenient operation.
Description of drawings
Fig. 1, overall structure of the present utility model are partly cutd open schematic representation.
The sectional view of Fig. 2, running shaft.
The sectional view of Fig. 3, fixed cover.
Embodiment
Referring to Fig. 1,2,3, this swivel joint has a running shaft 1 and a fixed cover 2, circumferential surface at described running shaft is provided with a plurality of annular gas tanks 101, in described running shaft, be provided with the corresponding radially air outlet hole 102 that communicates with annular gas tank with these air outlet hole 102 vertical axial admission holes 103 that communicate radially, on the peripheral wall of described fixed cover 2, be provided with and the described annular gas tank 101 corresponding air outlet holes that communicate 5, between described a plurality of annular gas tanks, be provided with annular seal groove 104 and be located at O-ring seals 3 in this annular seal groove, this O-ring seals 3 is used to isolate each gas circuit, and described fixed cover 2 is by a pair of rolling bearing 4,4 ' is installed on the running shaft 1.This example is provided with five gas circuits on running shaft 1, five axial admission holes 103 are along the running shaft circumference uniform distribution, they join by the flange plate of running shaft bottom and the gas circuit of sucker, and the air outlet hole 5 on the described fixed cover 2 is a threaded coupling, and they join by fixing gas path pipe and sourceof negative pressure.
During work, provide negative air pressure by sourceof negative pressure, gas enters each gas circuit in the running shaft 1 by sucker, and sourceof negative pressure is discharged and got back in the air outlet from the fixed cover 2 then, thereby form the negative-pressure sucking of sucker.
In order to increase the suction of sucker, the aperture in described radially air outlet hole 102 and axial admission hole 103 changes Φ 4.0 into from original Φ 3.2.
This example is the axially staggered both sides that are distributed in the fixed cover peripheral wall of a plurality of air outlet holes on the fixed cover 5, makes the working space of installation, maintenance of each gas circuit air outlet hole joint bigger, easy to operate.
