Abstract
A high precision intermission cam motion mechanism belongs to amelioration for a column cam mechanism, concretely containing a bolt A, a raceway frame, a steel ball, a spacing collar A, a main axis, a linear bearing with opening, a axis, a clamping ring A, a spacing collar B, a clamping ring B, a fixing bolt, a axial puller, a cam, a gear, a fixing frame, a velocity measurement unit component of permanent magnet direct current moment and a connecting bolt. The permanent magnet direct current moment passes force to the cam by means of a gear and the axial puller moves under the condition of the cam being restricted by a cam contour curve and then passes the force to the axis. The axis does the fro movement in the linear bearing with opening and complete the motion of numerous moving and stopping under the control of a photoelectricity switch and the velocity measurement unit component of permanent magnet direct current moment to realize the stepping imaging of aviation camera. The utility model is characterized in reasonable design, simple structure, being able to design different curve groove according to requirement, that is, the utility model can be used to realize the intermission movement of different work requirement.
Description
Technical field
The utility model relates to a kind of accurate camming movement mechanism, particularly a kind of highi degree of accuracy intermittent type camming movement mechanism.
Background technique
The higher pair mechanism that cam mechanism is made up of frame, cam and driven member or servo system, cam mechanism has following function: transmission, guiding and control.
Space cam mainly contains cylindrical cam, conical cam and globoid cam etc., and cylindrical cam and conical cam are commonly used for the calibration stepping mechanism.Another kind belongs to the dish type conjugation indexing cam mechanism of face cam category.
Because cam profile curve is that therefore, cam mechanism is subjected to the restriction of cam profile curve, except that realize also can being used for realizing the intermittent movement of job requirement the characteristics of motion of expection arbitrarily as the mechanical controller structure according to the design of the characteristics of motion of job requirement.
Known Chinese utility model patent 02241469.X discloses " improved type interlock rail mounted camming movement mechanism ", correspondence is provided with two high points of projection on the cam rail face, and the interior outer rim that is posted by cam respectively forms dislocation, the combination of camming movement mechanism and clutch is bullied, electric motor control rotates.Do not see other relevant reports.
Summary of the invention
The utility model highi degree of accuracy intermittent type camming movement mechanism has solved a difficult problem of aerial camera stepping imaging.
This highi degree of accuracy intermittent type camming movement mechanism is the improvement of cylindrical cam mechanism.Mainly form by cam mechanism assembly, the DC moment-unit assembly that tests the speed, optoelectronic switch assembly etc.Specifically comprise cam connecting cylinder, screw A, rail bracket, steel ball, spacer ring A, body shaft, open type linear bearing, axle, trim ring A, spacer ring B, trim ring B, Cock screw, dial axis, cam, gear, fixing frame, DC moment-unit assembly, attachment screw test the speed.
DC moment-unit the assembly that tests the speed is passed to cam with power by a pinion, dial axis is subjected to the restriction campaign of cam profile curve at cam, again power is passed to axle, axle back and forth movement in the open type linear bearing, under the control of optoelectronic switch and the DC moment-unit assembly that tests the speed, finish the moving number of number and stop a quick-return motion, thereby realize the stepping imaging problem in the aerial camera.
Advantage of the present utility model: reasonable in design, simple in structure, can design different curvilinear grooves as required, promptly can be used to realize the intermittent movement of different operating requirement.
Description of drawings
Fig. 1 represents highi degree of accuracy intermittent type cam rectangle groove developed outline figure of the present invention;
Fig. 2 represents highi degree of accuracy intermittent type camming movement mechanism structure schematic representation of the present invention.
Embodiment
Fig. 1 represents highi degree of accuracy intermittent type cam rectangle groove developed outline figure of the present invention.Cylindrical cam with curvilinear groove be drawn in length be 2 π R on shape, then this displacement diagram is the curvilinear groove center line of cylindrical cam on the external diameter developed surface, i.e. pitch curve.Curve of the present invention is that 2 π R are divided into 12 parts: wherein distribute to ten moving ten and stop for ten parts, promptly portion is forgiven one moving one and is stopped, and one moving one to stop being exactly that stepping once pauses once, distributes to anxious returning for two parts.The every rotation one-period of cylindrical cam is finished ten moving ten and is stopped an anxious function of returning, and gets back to original position again.
In addition, also can be divided into ten parts to cam theoretical curve 2 π R: wherein distribute to eight moving eight and stop for eight parts, promptly portion is forgiven one moving one and is stopped, and one moving one to stop being exactly that stepping once pauses once, distributes to anxious returning for two parts.The every rotation one-period of cylindrical cam is finished eight moving eight and is stopped an anxious function of returning, and gets back to original position again.
The moving number of number stops a quick-return motion, can design 5-10 time with the motor revolution according to actual needs.
Represent highi degree of accuracy intermittent type camming movement mechanism structure schematic representation of the present invention with reference to Fig. 2.Highi degree of accuracy intermittent type camming movement mechanism mainly is made up of test the speed unit assembly 17, attachment screw 18 of cam connecting cylinder 1, screw A2, rail bracket 3, steel ball 4, spacer ring A5, body shaft 6, open type linear bearing 7, axle 8, trim ring A9, spacer ring B10, trim ring B11, Cock screw 12, dial axis 13, cam 14, gear 15, fixing frame 16, DC moment one.
Its annexation and working procedure: attachment screw 18 is connected workpiece, DC moment-unit assembly 17 driven gears 15 test the speed, gear 15 and cam connecting cylinder 1 gear that partners promptly drives the rotation of cam connecting cylinder, and cam connecting cylinder 1, rail bracket 3 and cam 14 are combined, cam 14 is rotation thereupon also, drive dial axis 13 motions, be subjected to the restriction of cam profile curve, dial axis 13 is in body shaft 6 and open type linear bearing 7, moving linearly is finished the moving number of number and is stopped an anxious function of returning.Thereby solve the stepping imaging problem of aerial camera.
