The utility model is characterized in that a servo electrical machine of the servo electrical machinery system (3) is in transmission connection with one end of a leading screw (5) of a roller screw through a wheel box (4); a handspike (6) is mounted on the leading screw (5), and the handspike (6) is fixedly connected with a nut of the roller screw. The utility model uses the roller screw as the driving part, which has the advantages of a controllable speed and displacement, high precision, big pushing power, small size, long life-span and convenient mount, etc.
Description
Technical field
The utility model relates to a kind of electric linear actuator, especially servoBcylinder.
Background technology
Usually the linear actuators that straight-line displacement can be provided that generally uses is hydraulic cylinder and pneumatic linear actuator.But in a lot of fields, especially in the demanding field of control precision, hydraulic cylinder and pneumatic linear actuator can't satisfy instructions for use.As a kind of position of needs such as product assembly line, automated packaging equipment, parallel machine, electric injection molding machine, metallurgical connection casting crystallization vibrator and speed can accurately be controlled or multi-cylinder accurately links controls and the big servoBcylinder of thrust.
The utility model content
The purpose of this utility model provides a kind of displacement and speed-controllable, precision height, servoBcylinder that thrust is big.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of servoBcylinder, comprise servo electrical machinery system, its special feature is that the servomotor of this servo electrical machinery system is in transmission connection by leading screw one end of a transmission case and a roller screw, be set with a push rod on leading screw, this push rod is fixedlyed connected with the nut of this roller screw.
Wherein transmission case and roller screw are installed in the housing.
Further, a gathering sill parallel with roller screw arranged in housing wherein, on push rod, be equipped with one and cooperate directed projection with this gathering sill.
Wherein on housing, limit switch is installed so that determine the residing extreme position of push rod.
Wherein on housing, buffer unit is installed with the residing extreme position of push rod corresponding position.
Further, wherein on push rod, connecting bolt is installed in case be pushed thing and be connected.
Wherein servo electrical machinery system comprises servomotor and control and drive part.
The utility model has adopted roller screw as drive disk assembly, has speed displacement may command, precision height, thrust is big, volume is little, the life-span is long, advantage such as easy for installation.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Come the utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises servo electrical machinery system 3 (comprising servomotor and control thereof and drive part), the servomotor of this servo electrical machinery system 3 is in transmission connection by leading screw 5 one ends of a transmission case 4 and a roller screw, be set with a push rod 6 on leading screw 5, this push rod 6 is fixedlyed connected with the nut of this roller screw.
As shown in Figure 1, transmission case 4 and roller screw are installed in the housing 9, and a gathering sill parallel with roller screw arranged in housing 9, and on push rod 6, be equipped with one and cooperate directed projection 7 with this gathering sill, thus 6 rotations of anti-throw-out lever.On housing 9, limit switch 10 is installed also so that determine push rod 6 residing extreme positions, can when push rod 6 reaches the limit of the position, provides signal, to avoid damaging leading screw 5.On housing 9, buffer unit 8 is installed,, can avoids leading screw 5 to damage equally as cushion pad etc. with push rod 6 residing extreme position corresponding positions.
As shown in Figure 1, on push rod 6 low order end connecting bolt is installed in case be pushed thing and be connected.
Operation principle of the present utility model is:
Servo electrical machinery system 3 drives leading screw 5 rotations of roller screw by transmission case 4, the nut of corresponding roller screw promotes push rod 6 straight lines and moves, under the situation that does not require push rod 6 rotations, can realize by making to slide in the gathering sill of projection 7 on housing 9 on the leading screw 5.
Claims (7)
1, a kind of servoBcylinder, comprise servo electrical machinery system (3), it is characterized in that: the servomotor of this servo electrical machinery system (3) is in transmission connection by leading screw (5) one ends of transmission case (4) with a roller screw, be set with a push rod (6) on leading screw (5), this push rod (6) is fixedlyed connected with the nut of this roller screw.
