Abstract
The invention discloses a rotary electromagnet linear driving device so as to solve a problem that rotary motion of the rotary electromagnet is required to be converted into linear reciprocating motion in the prior art. The rotary electromagnet linear driving device comprises a frame, a rotary electromagnet, a cam and a movable platform capable of moving in a straight line, wherein the shaft of the cam is connected with the output shaft of the rotary electromagnet, the movable platform is provided with a driven member matched with the curved surface of the cam, a tension spring is connected between the movable platform and an adjusting seat on the frame, and the adjusting seat is slidably connected with a sliding groove in the frame and can change the position so as to adjust the tension of the tension spring. The output shaft of the rotary electromagnet disclosed by the invention outputs a twisting force to drive the cam to rotate, and the cam pushes the driven member and drives the movable platform to move. Meanwhile, the movable platform can also be reset under the action of the tension spring, and then pushed again by the cam.
Description
Technical field
The present invention relates to a kind ofly with variable gear ratio device, carry out mechanically operated mechanism.
Background technology
Electromagnet is that the electromagnetic attraction that utilizes current-carrying iron-core coil to produce is handled mechanical device, to complete a kind of electrical equipment of expection action.It is a kind of electromagnetic component that converts electrical energy into mechanical energy.Rotary magnet is the device that electromagnetic force can be exported in the mode of rotation or swing.
In some occasion, often need rotatablely moving of rotary magnet to be converted into straight reciprocating motion, how realizing such conversion is that people are devoted to perfect problem always.
Summary of the invention
The invention is intended to provide a kind of rotary magnet linear drive apparatus, to solve the problem that in prior art needs rotatablely moving of rotary magnet to be converted into straight reciprocating motion.
Rotary magnet linear drive apparatus in this programme, comprise frame and rotary magnet, it is characterized in that: also comprise cam, can straight-line travelling carriage, the axle of cam is connected with the output shaft of rotary magnet, travelling carriage is provided with the driven member coordinating with cam curved surface, between the adjustment seat in travelling carriage and frame, be connected with extension spring, the chute in adjustment seat and frame be slidably connected and variable position to regulate the pulling force of extension spring.
The output shaft outputting torsion band moving cam of rotary magnet rotation in said apparatus, cam is pushed driven member and is driven travelling carriage to move, and travelling carriage can also reset under the effect of extension spring simultaneously, and then by cam, is again promoted.
Further, in the limit position at the reciprocating two ends of travelling carriage, be respectively provided with a limit switch, described limit switch is connected with the controller of rotary magnet.The controller of rotary magnet can judge that position controls its operative orientation according to limit switch, realizes the auto reciprocating of whole mechanism.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the schematic top plan view of the embodiment of the present invention.
Embodiment
Reference numeral in Figure of description comprises: frame 1, rotary magnet 2, cam 3, cam follower 4, travelling carriage 5, adjustment seat 6, extension spring 7, limit switch 8.
Substantially as shown in Figure 1: in the present embodiment, comprise frame and rotary magnet, also comprise cam, can the straight-line travelling carriage of horizontal left and right directions, the axle of cam is connected with the output shaft of rotary magnet, on travelling carriage, be connected with the cam follower coordinating with cam curved surface, between the adjustment seat in travelling carriage and frame, be connected with extension spring, adjustment seat can be along the chute change of location of the left and right directions in frame to regulate the pulling force of extension spring, and available bolt is to fix simultaneously.In the limit position at the reciprocating two ends of travelling carriage, be respectively provided with a limit switch, described limit switch is connected with the controller of rotary magnet, is provided with the selection encoder that detects its rotation situation on the axle of cam.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic is not done unnecessary description at this, and part-structure also do not illustrate in the drawings, but does not affect person of ordinary skill in the field to the understanding of this technical scheme and realization.Should be understood that; for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
