Abstract
The utility model discloses an electric cylinder stroke mechanical positioning device, which comprises a movable slider. A cylinder is fixedly mounted on the movable slider, an oil port is arranged on one side of the body of the cylinder, a bumping block is sleeved at an extending end of a piston rod of the cylinder, the lower end of the bumping block is provided with a counter bore, a cylindrical base is mounted on the body of the cylinder at the extending end of the piston rod, and the piston rod penetrates through the cylindrical base. An adjustable stopper is fittingly mounted on the cylindrical base and driven by a motor, and an inner circular surface of the counter bore is in clearance fit with an outer circular surface of the cylindrical base. The height of the stopper is adjusted by the motor with a rotary encoder, so that an operator can directly set positions of the adjustable stopper on an industrial touch screen, not only operation of the operator is simple, but also displacement of a press head is accurately positioned. The electric cylinder stroke mechanical positioning device can be applied to various fields which have rigid requirements for stroke displacement.
Description
Technical field
The utility model relates generally to the accurate mechanical positioner of oil cylinder stroke in the stroke field of locating technology of various middle-size and small-size hydraulic presses, relates in particular to a kind of electrodynamic type oil cylinder stroke mechanical positioner.
Background technology
At present, known in various hydraulic press compactings, the displacement control of press slide or pressure head is a big technical problem, particularly in the powder press that travel displacement is had relatively high expectations, coil press, bearing press, its stroke mostly is to control by single hydraulic means in the existing hydraulic press, and its positioning accuracy is difficult to control, precision is low, troublesome poeration in the position fixing process is wasted time and energy simultaneously, has influenced the quality of workpiece.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of electrodynamic type oil cylinder stroke mechanical positioner is provided, more in the past with fluid pressure type location or other mechanical type, on the precision of position location, be significantly improved, realized the accurate location of displacement of pressing head, and simple to operate, can be applicable to a lot in the field that strict demand is arranged on the travel displacement.
The utility model is achieved through the following technical solutions:
A kind of electrodynamic type oil cylinder stroke mechanical positioner, include the motion slide block, be installed with oil cylinder on the described motion slide block, described cylinder block one side is provided with hydraulic fluid port, described oil cylinder piston bar external part end is set with collision block, it is characterized in that: described collision block lower end is provided with counterbore, on the cylinder body of described oil cylinder piston bar external part cylindrical base is installed, and piston rod passes cylindrical base, cooperate on the described cylindrical base adjustable block is installed, described adjustable block is by Motor Drive, the periphery matched in clearance of the inner headed face of described counterbore and cylindrical base.
Described electrodynamic type oil cylinder stroke mechanical positioner is characterized in that: dispose rotary encoder on the described motor.
Described electrodynamic type oil cylinder stroke mechanical positioner, it is characterized in that: the periphery of described adjustable block is the flank of tooth, and the sprocket of an adjustable block and a side is connected by meshing transmission, and is in transmission connection by angular wheel and gear and sprocket between described sprocket and the motor output end.
Described electrodynamic type oil cylinder stroke mechanical positioner, it is characterized in that: described sprocket is fixedly mounted on the support, and described support is fixedly mounted on the entablature, and described entablature is fixedly mounted on the cylinder block.
Its operation principle: the position that is used for regulating adjustable block by mechanical mechanical driving devices such as motor drives bevel gear and gear, tooth posts, this position can directly be set in graphic control panel by the site operation personnel when operation simultaneously, with the rotation number of turns of rotary encoder identification motor, mechanical driving devices such as motor drives bevel gear, gear, tooth post are regulated the height of block.When oil cylinder when descending, collision block clashes into adjustable block represents that promptly the lower limit position of suppressing arrives, the intensity of block can be born the downforce of oil cylinder, oil cylinder will be no longer descending this moment, only carry out pressurize, the dwell time is finished a technological action to getting final product backhaul.Position with adjustable block guarantees the position that oil cylinder is descending, thereby realizes the accurate machinery location of the stroke of oil cylinder.
This structure with fluid pressure type location or other mechanical type etc., was significantly improved on the precision of position location more in the past, and simple to operate, and the accurate location of having realized displacement of pressing head is applied in a lot of fields that strict demand arranged on to travel displacement.
The utility model has the advantages that:
The utility model adopts mechanical driving devices such as motor drives bevel gear, gear, tooth post to regulate the height of block, the rotating cycle of motor is discerned by rotary encoder, convert through PLC, operating personnel can directly set the position of adjustable block in graphic control panel, not only personnel operation is simple, and the accurate location of having realized displacement of pressing head, in a lot of fields that strict demand arranged on to travel displacement, be applied.
