Abstract
The utility model discloses a rotary electromagnet linear driving device to solve a problem that the rotary movement of a rotary electromagnet is needed to be converted into straight reciprocating movement in the prior art. The rotary electromagnet linear driving device comprises a frame, a rotary electromagnet, a cam, and a moving platform capable of moving in a straight line. The shaft of the cam is connected with the output shaft of the rotary electromagnet. The moving platform is provided with a follower which is matched with the curved surface of the cam. A tension spring is connected between the moving platform and an adjusting seat on the frame. The adjusting seat is slidingly connected with the sliding groove on the frame, and the position of the adjusting seat can be changed to adjust the tension of the tension spring. According to the rotary electromagnet linear driving device, the output shaft of the rotary electromagnet outputs torque to drive the cam to rotate, the cam pushes the follower and drives the moving platform to move, and at the same time the moving platform can be reset under the effect of the tension spring and then is pushed by the cam again.
Description
Technical field
The utility model relates to one variable gear ratio device and carries 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.
Often need rotatablely moving of rotary magnet to be converted into straight reciprocating motion in some occasion, how realizing such conversion is that people are devoted to perfect problem always.
Utility model content
The utility model 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, is and then again promoted by cam.
Further, be respectively provided with a limit switch in the limit position at the reciprocating two ends of travelling carriage, 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.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the schematic top plan view of the utility model embodiment.
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.Respectively be provided with a limit switch in the limit position at the reciprocating two ends of travelling carriage, 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 embodiment of the present utility model, in scheme, the general knowledge such as known concrete structure and characteristic is not done unnecessary description at this, and part-structure does not also illustrate in the drawings, but does not affect understanding and the realization of person of ordinary skill in the field to this technical scheme.Should be understood that; for a person skilled in the art, not departing under the prerequisite of the utility model structure, can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
