Existing corner cylinder (when especially pressure is lower than 0.1MPa) aspect range of application is restricted.
Summary of the invention
In view of the defect of existing single action corner cylinder, the purpose of this utility model is to provide and a kind of during lower than 0.1MPa, still can realizes the low rotary resistance single action corner cylinder of corner cylinder substrate hold-down function at pressure.
The utility model adopts following technical scheme to achieve these goals: comprise cylinder body, be arranged on piston and return spring in described cylinder body; Between piston and cylinder body, sealing ring is set, has pressure chamber in cylinder body, the feed liquor/pore being arranged on described cylinder body communicates with described pressure chamber; Also there is corner pressing plate bar, described corner pressing plate bar is through piston, one end of corner pressing plate bar is connected with pressing plate, the other end of corner pressing plate bar stretches in cylinder body and fixes with one end of corner guide post, corner fairlead and cylinder body are fixed, and between corner guide post and corner fairlead, corner guide frame are set.
Operation principle of the present utility model is as follows: in the time that hydraulic pressure or air pressure enter pressure chamber, promote piston to left movement, and piston and corner pressing plate bar and corner guide post are not mobile between axially, just drive corner pressing plate bar and pressing plate to be moved to the left, while is under the effect of the spiral grooved of guide finger and gathering sill, make corner pressing plate bar and corner guide post produce screw with respect to cylinder body, thereby realize a band dynamic pressure plate screw left side, turn over after certain angle, guide finger enters the straight trough part of gathering sill, thereby realize the substrate hold-down function of corner cylinder to left movement with dynamic pressure plate straight line.
In the utility model, piston and cylinder body are provided with sealing ring, and between corner pressing plate bar and corner guide post and piston and cylinder body, there is no seal, between corner pressing plate bar and corner guide post and piston, axially do not move, between corner pressing plate bar and corner guide post and piston, circumferentially can freely rotate, corner pressing plate bar and corner guide post and pressure chamber are isolated completely, the resistance in corner pressing plate bar when motion is reduced greatly, be conducive to corner cylinder and realize during lower than 0.1MPa at pressure the substrate hold-down function of corner cylinder.
Based on said structure, the utility model is more widely used corner cylinder aspect range of application, especially in the situation of pressure lower than 0.1MPa.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 to 4, a kind of low rotary resistance single action corner cylinder, comprises cylinder body 5, is arranged on piston 4 and return spring 8 in described cylinder body 5; Between piston 4 and cylinder body 5, sealing ring 16 is set, has pressure chamber 17 in cylinder body 5, the feed liquor/pore 6 being arranged on described cylinder body 5 communicates with described pressure chamber 17; Also there is corner pressing plate bar 2, described corner pressing plate bar 2 is through piston 4, one end of corner pressing plate bar 2 is connected with pressing plate 3, the other end of corner pressing plate bar 2 stretches in cylinder body 5 and fixes with one end of corner guide post 14, the other end of corner guide post 14 can free in and out corner fairlead 11, corner fairlead 11 is fixing with cylinder body 5, between corner guide post 14 and corner fairlead 11, corner guide frame is set. The free end of described corner pressing plate bar 2 is by clamp nut 1 fixation clip 3.
In order to make the resistance of corner pressing plate bar 2 in rotation process less, to make at pressure during lower than 0.1MPa, corner cylinder has better substrate hold-down function, in said structure, between described corner guide post 14 and piston 4, be provided with thrust bearing 7, and/or be provided with thrust bearing 15 between corner pressing plate bar 2 and piston 4. Described corner fairlead 11 is fixed on cylinder body 5 bottoms by hold-down screw 9. Between described corner fairlead 11 and cylinder body 5, be provided with back-up ring 10.
In embodiment of the present utility model, described corner guide frame is made up of guide finger 12 and gathering sill 13, and guide finger 12 is positioned at gathering sill 13, and gathering sill 13 comprises the axial straight trough at spiral section and spiral section two ends. In the time that pressure promotion piston is moved to the left, corner guide post and corner pressing plate bar are moved to the left together with also, guide finger enters the spiral section of gathering sill, corner guide post and corner pressing plate bar will rotate, thereby band dynamic pressure plate turns over certain angle, can be embodied as the angle range of 0-180 degree according to Spiral groove parameter.
