Abstract
The invention relates to a stroke self-positioning device of reciprocating machinery. The stroke self-positioning device consists of a threaded shaft, a supporting seat, a fixed spring seat, a spring, a movable spring seat and a positioning block. The positioning block is screwed on a screw thread in the middle of the threaded shaft; the movable spring seat and the spring are orderly mounted into two ends; the fixed spring seat is screwed in a thread section corresponding to the threaded shaft. The positioning block and a moving part move by means of the threaded shaft and a screw thread pair of the positioning block; the threaded shaft rotates, and the positioning block leans against the movable spring seat on one end and moves forwards, so the spring on the end is pressed; when moving to the set position, the screw thread pair releases and separates automatically, and the positioning block does not exceed the set position even the electric braking is failure. When the threaded shaft rotates reversely, screw holes of the positioning block also are guided into a screw of the threaded shaft by action of the pressed spring, and the positioning block moves to another end by action of the screw thread pair. The screw thread shaft alternatively changes the rotating direction, so that the positioning block and the moving part can achieve the reciprocating motion with the reliable stroke.
Description
Affiliated technical field
The present invention relates to a kind of to-and-fro motion machinery stroke self locating device.
Background technique
The mode that to-and-fro motion machinery is controlled stroke automatically is a lot, normally adopt the electromechanical mode to realize, utilize sensor to ask for the signal that the movement parts relative displacement produces, feed back to the programmable, intelligent controller, finish its task by instruction final controlling element behind the analyze.But guarantee that the normal operation of system is not that part is easy to thing yet, such as all needing actuation time of signal transmission and each actuator organic linking, operation debugging more complicated, stability is also not fully up to expectations, if still electric breaking down just very easily caused mechanical accident, the equipment of especially having relatively high expectations for operational reliability.
Summary of the invention
The invention provides a kind of to-and-fro motion machinery stroke self locating device, it is to transmit the mechanism that kinetic energy does reciprocating linear motion, and has reliable location and prevents that movement parts from surmounting the function of default stroke.
The present invention is achieved in that it is comprised of thread spindle, bearing, fixing spring seat, spring, movable spring seat, positioning block.Thread spindle is multidiameter shaft, and mid diameter is maximum, and place, large footpath establishes the screw thread that coincide with the positioning block screw, and large footpath adjacent both ends is established step, and the step place is the light circle, and this smooth and round section is for the dropout of positioning block screw thread and movable spring seat, spring moving telescopic; The other end of smooth and round section is the screw thread step that installs and fixes spring seat, and screw thread step outside path and bearing hole are movingly.One end of thread spindle is connected with prime mover.It is round table-like that movable spring seat profile is ladder, and circular hole is established at the center, and the large end of cylindrical is established the counterbore of mounting spring, and center hole and thread spindle smooth and round section Spielpassung can move freely at the thread spindle smooth and round section; Movable spring seat cylindrical path is consistent with the external diameter of place, thread spindle footpath broad in the middle screw thread, with the guiding counterbore Spielpassung of positioning block screw thread nose end.
Fixing spring seat profile is cylindric, and the tapped hole fixed with thread spindle established at the center, and an end is provided with the counterbore of mounting spring.
The positioning block profile is not restricted to one pattern, can adjust according to the actual requirements, but two large planes should be parallel, locates the identical tapped hole of screw thread perpendicular to large plane layout with the large footpath of thread spindle, and the two ends, hole are equipped with the counterbore step that diameter cooperates with movable spring seat cylindrical minor clearance.Positioning block can be directly as reciprocating part, or reciprocating part is attached on the positioning block as the interface components that reciprocating part is installed.The size of positioning block and reciprocating part stroke is then determined by the length of thread spindle footpath broad in the middle thread section.
Fixing spring seat, movable spring seat are made by metallic material or the north material of nylon.

Embodiment
The present invention transmits the mechanism that kinetic energy does reciprocating linear motion, and has reliable location and prevents that movement parts from surmounting the function of default stroke.Thread spindle (1) is multidiameter shaft, and place, large footpath establishes the screw thread that coincide with positioning block (6) screw, and large footpath adjacent both ends is established step, and the step place is the light circle, and this smooth and round section is for the dropout of positioning block (6) screw thread and movable spring seat (5), spring (4) moving telescopic; The other end of smooth and round section is the screw thread step that installs and fixes spring seat (3), and screw thread step outside path and bearing (2) hole coincide.One end of thread spindle (1) is connected with prime mover.It is round table-like that movable spring seat (5) profile is ladder, and circular hole is established at the center, and the large end of cylindrical is established the counterbore of mounting spring (4), and center hole and thread spindle (1) smooth and round section Spielpassung can move freely at thread spindle (1) smooth and round section; Movable spring seat (5) cylindrical path is consistent with the external diameter of place, thread spindle (1) footpath broad in the middle screw thread, with the guiding counterbore Spielpassung of positioning block (6) screw thread nose end.Fixing spring seat (3) profile is cylindric, and the tapped hole fixed with thread spindle (1) established at the center, and an end is provided with the counterbore of mounting spring (4).Positioning block (6) profile is not restricted to one pattern, but two large plane parallel are located the identical tapped hole of screw thread perpendicular to plane layout with the large footpath of thread spindle (1), and the two ends, hole are equipped with the counterbore that diameter cooperates with movable spring seat (5) cylindrical minor clearance.Positioning block (6) can be directly as reciprocating part, or reciprocating part is attached to the upper interface components as the installation reciprocating part of positioning block (6).The size of positioning block (6) and reciprocating part stroke is then determined by the length of thread spindle (1) footpath broad in the middle thread section.
Positioning block (6) is screwed on the screw thread at place, thread spindle (1) footpath broad in the middle thread spindle (1) two ends pack into successively movable spring seat (5), spring (4); Movable spring seat (5) external diameter small end inwardly, spring (4) one ends buckle in the counterbore of movable spring seat (5), fixing spring seat (3) is screwed in thread section corresponding to thread spindle (1), an end of spring (4) falls into the counterbore of fixing spring seat (3) again.The movement of positioning block (6) and movement parts is to depend on thread spindle (1) to realize with the screw pair of positioning block (6), rotate thread spindle (1), positioning block (6) moves forward against the movable spring seat (5) of an end, this end spring (4) by compression, when running to desired location, screw pair just separates voluntarily, positioning block (6) can only keep relatively rotating with thread spindle (1) in this position, when the time comes, even electric braking lost efficacy, positioning block (6) also can not be gone beyond the position of setting.When thread spindle (1) reversed, under the effect of compression spring (4), the screw of positioning block (6) was imported into again in the screw rod of thread spindle (1), and positioning block under the effect of screw pair (6) moves to the other end, finished and identical on last stage step.Along with thread spindle (1) alternately changes sense of rotation, positioning block (6) and movement parts will realize the reliable to-and-fro motion of stroke.
