Abstract
The invention relates to a precise force through rod cylinder. The front and rear ends of the cylinder body are respectively provided with a guide sleeve, the guide sleeve is connected with a gland; a piston rod penetrates the whole cylinder body and is matched with the inner hole of the guide sleeve; the two sides of the cylinder body are symmetrically provided with a bearing guiding device; and the bottom of the cylinder body and the bearing guiding device are all arranged on a sliding connection plate. The invention has the following advantages and beneficial effects: 1, the precise force through rod cylinder is in low pressure (less than or equal to 10KN) and in high pressure intensity (more than or equal to 8MPa); 2, the whole cylinder can not tilt when moving, operation is stable, and meanwhile friction is reduced, and service life is prolonged; 3, precise control on pressure can be realized, and pressure intensity can reach ideal controllable value.
Description
Technical field:
The present invention relates to a kind of oil cylinder, particularly a kind of precise force through rod cylinder.
Background technique:
Improve constantly along with the continuous upgrading of industry technologies such as Aero-Space, military project with to what the product total quality required, must propose higher requirement quality, price and the precision of component.And the phenomenon of deflection takes place in oil cylinder at the volley easily that in these fields, use at present, and it is not steady to work, and frictional force is big, so working life is low.And can't realize precision control, thereby cause pressure can't reach ideal controllable value pressure.
Summary of the invention:
The object of the invention just is to provide a kind of precise force through rod cylinder, and the high working efficiency of this oil cylinder, machining accuracy are high, quality is high.
Technological scheme of the present invention is: a kind of precise force through rod cylinder, comprise cylinder block and piston rod, and it is characterized in that: guide sleeve is equipped with at the forward and backward two ends of cylinder block respectively, is connected with gland on the guide sleeve; Piston rod connects the whole cylinder cylinder body, and piston rod cooperates with the guide sleeve endoporus; The bilateral symmetry of cylinder block is equipped with bearing guiding device; Cylinder block bottom is installed on the connecting plate, being installed on the sliding connection plate of bearing guiding device.
Above-mentioned bearing guiding device by be installed in guide rod on the sliding connection plate, be connected the connecting plate between cylinder block and the guide rod and be installed in connecting plate and guide rod between the guide rod guide pin bushing form.
Pressure transducer is equipped with in the end of above-mentioned piston rod; Oil cylinder be less than 10KN low-pressure, more than or equal to the oil cylinder of 8MPa High Voltage, the stage casing of piston is a piston head, and seal ring is housed on the piston head; Cooperate two oil pockets of formation with cylinder barrel, copper pilot seal cover is equipped with at the cylinder barrel two ends.
The present invention has following advantage and good effect:
1, because the piston rod of this oil cylinder connects the whole cylinder cylinder body, obtaining less annular bearing area, so this oil cylinder be low-pressure (≤10KN), High Voltage (>=8MPa) precise force through rod cylinder.
2, because piston rod connects the whole cylinder cylinder body, piston rod cooperates with the guide sleeve endoporus; The bilateral symmetry of cylinder block is equipped with bearing guiding device; Cylinder block bottom is installed on the connecting plate, and the bottom of bearing guiding device is installed on the sliding connection plate, so whole cylinder can deflection in movement process, stable working, and reduced friction, improved working life.
3, owing to pressure transducer is housed, therefore can realize precision control through extracting pressure signal at output terminal to pressure in the end of piston rod.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
As shown in the figure: a kind of precise force through rod cylinder, comprise cylinder block 4. with piston rod 1..3. the forward and backward two ends of cylinder block are equipped with guide sleeve respectively, are connected with gland on the guide sleeve 2.; Piston rod connects the whole cylinder cylinder body, and piston rod cooperates with the guide sleeve endoporus; The bilateral symmetry of cylinder block is equipped with bearing guiding device; The cylinder block bottom is installed on the connecting plate, and the bottom of bearing guiding device is installed in a sliding connection plate and 8. goes up.Above-mentioned bearing guiding device by be installed on the sliding connection plate guide rod 5., be connected between cylinder block and the guide rod connecting plate 7. and the guide rod guide pin bushing that is installed between connecting plate and the guide rod 6. form.Pressure transducer is equipped with in the end of above-mentioned piston rod 9., and pressure head is equipped with in the bottom of pressure transducer 10..
A kind of low-pressure that the present invention requires to design for the control that adapts to accurate power (≤10KN) High Voltage (>=8MPa) precise force through rod cylinder.The piston rod of this oil cylinder connects whole cylinder, to obtain less annular bearing area, therefore makes pressure can reach ideal controllable value.The stage casing of piston is a piston head, and seal ring is housed on the piston head, cooperates with cylinder barrel to form two oil pockets; Copper pilot seal cover is equipped with at the cylinder barrel two ends, is connected with preceding gland before the guide sleeve, and piston rod cooperates with the guide sleeve endoporus; Because of piston rod through rod axle, both sides all have supporting and guiding to overcome the deflection between motion, reduce friction; Stable working improves working life.Pressure transducer is equipped with in end at piston rod, through extracting pressure signal at output terminal, realizes the precision control to pressure.
