Accompanying drawing explanation
Fig. 1 is the structural representation with the electric cylinder of pooling feature of the present utility model.
Embodiment
As shown in Figure 1, be the structural representation with the electric cylinder of pooling feature of the present utility model.The utility model has cylinder body 10, and cylinder body 10 front end is covered with fixing end cap 2 by screw 3.Be provided with the trunk-piston bar 4 of hollow in cylinder body 10, the front end of trunk-piston bar 4 is located in fixing end cap 2.Motor bolt 1 is connected with trunk-piston bar 4.Trunk-piston bar 4 is inner is installed with leading screw front support bearing 5 near front end place, and rear end is provided with piston rod holder 8.Cylinder body 10 rear end is provided with CD-ROM drive motor 15, and CD-ROM drive motor 15 is fixed on motor fixing base 13, and is connected with electromagnetic brake device 16, for carrying out mechanical brake to CD-ROM drive motor 15.Be provided with ball-screw 6 in trunk-piston bar 4, ball-screw 6 rear end is in transmission connection by shaft coupling 14 and CD-ROM drive motor 15, drives ball-screw 6 to move back and forth; Front end is connected with leading screw front support bearing 5, to ensure the axiality that ball-screw 6 rotates.Piston rod holder 8 is provided with magnet steel 9 in cylinder body 10 contact-making surface, cylinder body 10 in corresponding to the axial location of magnet steel 9 be provided with upper limit Hall 7 near front end place, for responding to the magnet steel 9 that trunk-piston bar 4 moves upward in process on piston rod holder; Cylinder body 10, in corresponding to the axial location of magnet steel 9 be provided with lower limit Hall 12 near rear end, moves downward magnet steel 9 in process on piston rod holder 8 for responding to trunk-piston bar 4.Spring 11 is provided with, the kinetic energy that the extraneous acceleration of gravity brought for damper piston bar holder 8 brings between piston rod holder 8 and motor fixing base 13.
The operation principle that the utility model has the electric cylinder of pooling feature is as follows: after the trunk-piston bar 4 in electric cylinder receives the order of upward vertical movement, electromagnetic brake device 16 By Electrolysis is except the locking to CD-ROM drive motor 15, CD-ROM drive motor 15 is rotated counterclockwise, drive shaft coupling 14 to rotate, the nut on the ball-screw 6 be connected with shaft coupling 14 can upward vertical movement.Under this motion state; electric cylinder is having the startup under load condition; spring 11 can remove the stress of its inside of abrupt release of locking at electromagnetic brake device 16; this internal stress can act on piston rod holder 8; to reduce the drive current of CD-ROM drive motor 15 when starting instantaneously, play the function of protection CD-ROM drive motor 15 and motor driver.When the magnet steel 9 be positioned on piston rod holder 8 senses upper limit Hall 7, CD-ROM drive motor 15 power down, the rotor of electromagnetic brake device 16 power down locking CD-ROM drive motor 15.The action of trunk-piston bar 4 upward vertical movement completes.
After the trunk-piston bar 4 in electric cylinder receives the order of vertical downward movement, electromagnetic brake device 16 By Electrolysis is except the locking to CD-ROM drive motor 15, CD-ROM drive motor 15 turns clockwise, and drive shaft coupling 14 to rotate, the nut on the ball-screw 6 be connected with shaft coupling 14 can vertical downward movement.Because ball-screw 6 and CD-ROM drive motor 15 itself do not possess good self-lock force, when carrying loaded trunk-piston bar 4 and being moved downward by CD-ROM drive motor 15 driving, larger moment of inertia can be produced, when piston rod holder 8 moves to spring 11 contact-making surface, spring 11 can cushion the inertia kinetic energy that extraneous load brings, the linear change of thrust due to spring 11, inertia kinetic energy can be eliminated by the elastic force of spring 11 completely and the masterpiece producing upward direction is resistance, the ball-screw 6 on shaft coupling 14 is driven to continue to be with carrying to move downwards by CD-ROM drive motor 15, when the magnet steel 9 on piston rod holder 8 is when sensing lower limit Hall 12, move downward action to complete.
From the operation principle of above electric cylinder, when spring of the present utility model replace by the relative magnet of same polarity time as being located at piston rod holder 8 with magnet, another magnet same polarity is relatively arranged on motor fixing base 13 also can produce identical inertia kinetic energy buffering effect.Again such as, when piston rod holder 8 and motor fixing base 13 form confined space in electric cylinder, the similar principles such as the gas flow resistance that formed of mutually moving realize the cushioning effect of inertia kinetic energy.
