Abstract
The present invention relates to an oil cylinder driving spiral conversion longitudinal joint for a robot, which comprises an oil cylinder, a multiple rolling screw pair, a rolling spline pair and an output connector. The oil cylinder driving spiral conversion longitudinal joint is characterized in that a spline shaft of the rolling spline pair is connected with a piston rod of the oil cylinder; a spline sleeve is connected with an oil cylinder sleeve so as to ensure that the spline shaft can only make axial movement and the spline shaft bears the reactionary torque of a load; a spiral shaft of the multiple rolling screw pair is integral with the spline shaft, and a spiral sleeve is connected with the output connector so as to complete the conversion of the oil cylinder from linear motion to rotary movement; a thrust bearing pair which can constrain the spiral sleeve to make oscillating movement round a shaft line of the spiral sleeve and not to make axial movement is arranged between the spline sleeve and the spline sleeve. The present invention omits a speed reducing mechanism and has the characteristics of simple structure, small dimension, large output torque and each digital control. The present invention is a robot basic driving member which is convenient to realize generalization, modularization and standardization.
Description
Technical field
The present invention relates to a kind of robot field's of belonging to the vertical cradle head of robot.
Background technology
At present, the industrial machine philtrum has the employing worm and worm gear, planetary gears, and rack and pinion mechanism, vertical cradle head of various ways such as swinging cylinder mechanism, majority exists size bigger, or moment is less, or problems such as low precision or motion instability.
Summary of the invention
The objective of the invention is: provide a kind of with hydraulic actuation power source, the industrial machine human is the vertical cradle head of square energetically.
For addressing the above problem, technical scheme of the present invention is such, it is the vertical cradle head of a kind of robot, comprise oil cylinder, the screw rod of forming by straight spline segment and bull rolling screw section, the spline segment overcoat, spiral section overcoat, thrust bearing component, input adapter and out splice going splice, it is characterized in that: thrust bearing component is by outer shroud, interior ring, steel ball, plug and pin constitute can bear radially three axial thrust bearings with positive and negative two axial load, ring is by spline segment overcoat double as wherein, is provided with on outer shroud that dress is got the radial hole of steel ball and by the locking of plug and pin, with screw thread with the spline segment overcoat, outer shroud and spiral section overcoat link together.
In said structure, directly finish the conversion of rectilinear movement to rotating motion by the bull rolling screw section of screw rod.
Description of drawings
Fig. 1 is the structural representation of the vertical cradle head of robot of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the vertical cradle head of robot of the present invention is described further.
As shown in Figure 1, the vertical cradle head of robot of the present invention is made up of following part: oil cylinder 1, the screw rod of forming by straight spline segment and bull rolling screw section 3, spline segment overcoat 2, spline segment steel ball 4, spline segment synchronizing sleeve 5, spiral section overcoat 9, spiral section synchronizing sleeve 10, thrust bearing component, input adapter and out splice going splice 11.Input adapter is the cover of band internal and external screw thread, and it designs together with oil cylinder, is connected with the machine human body with its interior or external screw thread.After pressure oil enters oil cylinder 1, promote piston rod by piston, lead-screw 3 moves axially again, directly drives spiral section overcoat 9 through steel ball and rotates, and is passed to the execution part of robot by out splice going splice 11.
Thrust bearing component is by outer shroud 6, by the interior ring of spline segment overcoat 2 double as, and steel ball 8, three axial thrust bearings that plug 7 and pin 7 ' constitute.Being provided with dress on outer shroud 6 gets the radial hole of steel ball 8 and by the 7 ' locking of plug 7 and pin, with screw thread spline segment overcoat 2, outer shroud 6 and spiral section overcoat 9 is linked together.
