Description
Technical field:
The invention belongs to mechanical transmission structure technical field, be specifically related to a kind of magnetic six bar mechanism.
Background technique:
Six bar mechanism is widely used in a lot of modern comfort, as numerical control machine tool, 3D printer, sorting system etc.What connecting rod one end connected is equipment executive module, and as print head, cutter or Pneumatic suction cup etc., in order to realize different functions, what the connecting rod the other end connected is power-transmitting unit, is positioned and specific orbiting motion by power-transmitting unit drivening rod.
Traditional six bar mechanism mainly connects executive module and power-transmitting unit by univesal sphere joint or univesal sphere bearing, univesal sphere joint forms primarily of joint framework, lining and cardon link, lining is between joint framework and cardon link, play the effect of lubrication, although lagging material belongs to high-abrasive material, but be through long operation, lining still has wearing and tearing unavoidably, produce gap, thus the precision making operation locate reduces, in addition because the generation in gap also easily produces noise, acoustic environment is impacted.Cardon link carries out Universal rotary motion in lining, because cardon link will connect connecting rod, so cardon link is when rotation, the angle limits rotated is larger, as six-bar linkage driving mechanism, angle of swing restriction is large, so directly affects the range of this mechanism kinematic, limits the performance of some performance of equipment.In addition, traditional six bar mechanism Installation and Debugging are cumbersome, due to the problem that univesal sphere joint produces, can only be that problematic univesal sphere joint is removed, then change new, more again debug.Like this, because of the quality problems in univesal sphere joint itself, and very troublesome installation and adjustment work is brought.
Summary of the invention:
The object of the invention is in order to solve produce gap between traditional six bar mechanism joint framework and cardon link after operation is located precision to reduce and the angle limits producing noise and rotation is comparatively large and the troublesome problem of Installation and Debugging, provide a kind of magnetic six bar mechanism, its technological scheme is as follows:
A kind of magnetic six bar mechanism, it comprises upper mounting plate, lower installation board, guide rail, slide block, connecting rod, club, ball-joint, executive module; Described guide rail is arranged between upper mounting plate and lower installation board, slide block is arranged on guide rail and is connected with slide, the two ends of described connecting rod are provided with club and ball-joint, club is fixedly connected with connecting rod, ball-joint is connected with magnetic force with club, the ball-joint of small end is connected with magnetic force with slide block, and the ball-joint of connecting rod lower end is connected with magnetic force with executive module; The pit consistent with ball-joint surface radian is provided with at slide block and the surface of contact of ball-joint and the surface of contact of executive module and ball-joint.
Beneficial effect of the present invention is: the gap can eliminated ball-joint and slide block and produce because of long-play between ball-joint and executive module, and keep the precision running location also to avoid producing noise, add the angle of rotation, Installation and Debugging are convenient.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment:
With reference to Fig. 1, a kind of magnetic six bar mechanism, it comprises upper mounting plate 1, lower installation board 2, guide rail 3, slide block 4, connecting rod 5, club 6, ball-joint 7, executive module 8; Described guide rail 3 is arranged between upper mounting plate 1 and lower installation board 2, slide block 4 arranges and is slidably connected with guide rail 3 on guides 3, the two ends of described connecting rod 5 are provided with club 6 and ball-joint 7, club 6 is fixedly connected with connecting rod 5, ball-joint 7 is connected with magnetic force with club 6, club 6 and the surface of contact of ball-joint 7 are provided with the pit consistent with the surperficial radian of ball-joint 7, and the ball-joint 7 of connecting rod 5 upper end is connected with magnetic force with slide block 4, and the ball-joint 7 of connecting rod 5 lower end is connected with magnetic force with executive module 8; The pit consistent with the surperficial radian of ball-joint 7 is provided with the surface of contact of ball-joint 7 and the surface of contact of executive module 8 and ball-joint 7 at slide block 4.
Embodiment one, described club 6 adopts steel matter, and described ball-joint 7 adopts magnet material, and at the surface of contact of ball-joint 7 with slide block 4, ball-joint 7 arranges high-abrasive material teflon lining form with the surface of contact of executive module 8, reduces amount of friction.
Embodiment two, described ball-joint 7 adopts steel matter, and described club 6 adopts magnet material.
Inventive principle: slide block 4, ball-joint 7, club 6 are connected with executive module 8, ball-joint 7, club 6 by the magnetic force of ball-joint 7 or club 6, and its surface of contact is consistent with the cambered surface of ball-joint 7, connecting rod 5 is made to be free to rotate on magnetic ball surface like this, can not depart from, and automatically eliminate the gap of friction generation, keep the highi degree of accuracy of this mechanism in movement process.Do not need to need ball-joint 7 to surround more than 1/2nd as joint framework in conventional construction, so the part that ball-joint 7 is exposed increases, make the activity point of view of connecting rod 5 increase like this.Magnetic force connects also makes installment and debugging more convenient, can ball-joint 7 and slide block 4 grade be separated very easily.
