Summary of the invention
The purpose of this utility model provides a kind of medicine equipment with four guide pillar self-raising platform mechanisms, overcomes shortcomings such as existing self-raising platform difficulty of processing is big, processing charges is high, assembly precision difference.
A kind of medicine equipment is with four guide pillar self-raising platform mechanisms, the four guide pillar linear motion systems that it comprises upper table surface, base, be made up of linear bearing and cylinder axis, by ball-screw, servomotor and by the automatic lifting drive system that motor to the transmission device of leading screw is formed, be characterized in:
A) described four guide pillar linear motion systems: upper table surface is vertical affixed respectively with four cylinder axis; Distinguishing on the cooresponding bases with four cylinder axis positions, be connected with four coaxial with cylinder axis respectively linear bearings, four linear bearings are nested in respectively in the cooresponding cylinder axis;
B) described automatic lifting drive system: be on base, to be connected with servomotor, the transmission shaft of servomotor is connected with the transmission device of base below, ball-screw links to each other with the axle center of transmission output wheel, the ball-screw supported end links to each other with base, is fixed in the upper table surface inboard with the nut of the coaxial socket of ball-screw.
Described ball-screw can adopt two ball-screws or single ball-screw feeding type of drive.
Described servomotor can adopt AC servo motor, also can adopt stepping motor or other reducing motor.
The utility model adopts four guide pillar self-raising platform mechanisms, four cylinder axis cooperate with linear bearing has formed the round guide pair, its structure does not need the framed structure that four line slideways are installed, the supporting of upper table surface and base and motion are born by 4 cylinder axis, physical construction is simple, has save the framework of rigidity, manufacturability difference; Add man-hour, only need cylinder axis place and base installation linear bearing place butt flange face to be installed, bore the circular hole of four pairings, and bore cooresponding screw/nut mounting hole at upper table surface and base at upper table surface, on common boring machine, can process easy to process, right alignment positional precision height; And the price of linear bearing is lower than line slideway, can choose thick cylinder axis of diameter and linear bearing, has not only improved mechanism's rigidity, but also has reduced manufacturing cost; Promote nut by motor by transmission device Dai Dong Silk Gang ， Silk thick stick, drive nut promotes the table top lifting.
The utility model lifting detects control system and can adopt linear grating chi closed loop control system, also can adopt motor to carry half-closed loop control system or other position detection control system of round grating.
Motor to the transmission device of leading screw can adopt gear transmission, also strap drive synchronously, and other can guarantee the driving device of transmission accuracy.
On the upper table surface, can dispose various medical inspection devices, carrying patient's therapeutic bed perhaps is installed according to medical application; Also left and right displacement mechanism can be installed on base, expanding bay-lift is two dimension or three-dimensional multi-purpose desk.
The utlity model has simple in structurely, process and assemble is easy, and is easy to use, and cost is low, lifting precision advantages of higher.The automatic lifting that not only can be used for medicine equipment, and can be widely used in various lifting mechanisms such as miscellaneous equipment outside the medicine equipment, experimental apparatus.
