Abstract
The utility model discloses a precision force through rod oil cylinder with low pressure and high pressure intensity. A guide sleeve is respectively arranged at the front end and the rear end of a cylinder body of the oil cylinder, and a gland bush is connected to each guide sleeve; a piston rod passes through the entire cylinder body of the oil cylinder, and is matched with the inner holes of theguide sleeves; bearing and guiding devices are symmetrically mounted on the two sides of the cylinder body of the oil cylinder; and the bottom part of the cylinder body of the oil cylinder and the bearing and guiding devices are all mounted on a slip connection plate. The utility model has the advantages and benefits as follows: 1, the oil cylinder is classified as a precision force through rod oil cylinder with low pressure ( less than or equal to 10 KN ) and high pressure intensity (more than or equal to 8 MPa); 2, the entire oil cylinder is avoided from deflection during the motion process, the working is smooth, the friction is reduced, and the service life is improved; and 3, the precision pressure control can be achieved, so that the pressure intensity can reach an ideal controllable value.
Description
Technical field:
The utility model relates to a kind of oil cylinder, the precise force through rod cylinder of particularly a kind of low-pressure, High Voltage.
Background technique:
Along with the continuous upgrading of industry technologies such as Aero-Space, military project with to improving constantly that the product total quality requires, higher requirement must be proposed to quality, price and the precision of component.And the phenomenon of deflection takes place in oil cylinder at the volley easily that use in these fields 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 purpose of this utility model just is to provide the precise force through rod cylinder of a kind of low-pressure, High Voltage, the high working efficiency of this oil cylinder, machining accuracy height, quality height.
The technical solution of the utility model is: the precise force through rod cylinder of a kind of low-pressure, High Voltage, 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; Being installed on the sliding connection plate of cylinder block bottom and 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.
The utlity model 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; The bottom of cylinder block and 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 by 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 utility model.
Embodiment:
As shown in the figure: the precise force through rod cylinder of a kind of low-pressure, High Voltage, 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 bottom of cylinder block and 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 utility model 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, 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, is connected with preceding gland before the guide sleeve, piston rod cooperates with the guide sleeve endoporus, because of piston rod through rod axle, both sides all have supporting and guiding to overcome deflection between motion, reduce friction, stable working improves working life.Pressure transducer is equipped with in end at piston rod, by extracting pressure signal at output terminal, realizes the precision control to pressure.
