Abstract

The utility model discloses a device which converts the pivoting motion into the straight reciprocating motion, wherein, a pivoting motion mechanism composed of a rotary wheel fixed and connected with the rotary shaft of an actuating unit is fixed with a magnet at the rotary wheel deviating from the rotating center, and a straight reciprocating motion mechanism is arranged outside the rotary shaft corresponding to the rotating path. The straight reciprocating motion mechanism comprises a guide mechanism arranged along the direction of the straight reciprocating motion, and a magnetic piston which can do the straight reciprocating motion in the guide mechanism is arranged on the guide mechanism. The device adopts magnetic force to convert the pivoting motion into the straight reciprocating motion and provides a bran-new motion conversion mode and a transformational structure, and the structure is novel and simple; the mechanism has no connecting bar which is connected with the pivoting motion parts with the straight reciprocating motion parts, no friction exists, and the failure rate is decreased; due to the non-contact performance of the magnetic force, the non-contact motion conversion and the dynamic transferring can be realized in two sealed and independent environments.

Description

Rotatablely move and be converted to the device of straight reciprocating motion
Technical field
The utility model relates to a kind of movement transforming device, and especially a kind of will rotatablely moving is converted to the device of straight reciprocating motion.
Background technology
At present, circular motion etc. is rotatablely moved be converted to straight-line device and comprise following several: the device that constitutes by bent axle, eccentric wheel or runner and connecting rod, the device that constitutes by cam and push rod, the device that passes through the gear interlock.Said apparatus all is the connection by mechanical part, the transmission of realizable force, and realize the conversion of motion, and all belonging to the conversion equipment of contact, the essential reliable contact of its each parts also connects.Because this mechanical connection can cause the wearing and tearing of connecting portion, working long hours to cause failure rate to increase, can't move; And, can't be implemented in particular cases noncontact movement conversion and transmission of power because parts link together.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of novel, the movement conversion parts need not to contact and realize rotatablely moving and be converted to the device of straight reciprocating motion.
The technical scheme of Cai Yonging is to achieve these goals: the rotational motion mechanism in that a runner of fixedlying connected with the actuating unit rotating shaft constitutes, depart from its rotary middle point and be fixed with magnet on runner; Outside runner with the corresponding linear reciprocating mechanism that is provided with of its magnet rotate path, linear reciprocating mechanism comprises the guiding mechanism that is provided with along the straight reciprocating motion direction, guiding mechanism is provided with magnetic piston, and magnetic piston can be done straight reciprocating motion in guiding mechanism.
Its linear movement direction of magnetic piston upper edge of described device is fixedly connected with power rail.
Described device is provided with spring at magnetic piston upper edge linear movement direction.
Said apparatus rotates under the driving of actuating unit rotating shaft when runner, and magnet fixing it on is also along with rotation, when magnet near and during over against guiding mechanism because the effect of magnetic force between magnet and magnetic piston, make magnetic piston close or away from runner; Magnet continues rotation away from guiding mechanism, and the magnetic force between magnet and magnetic piston weakens, and magnetic piston resets under the effect of gravity or spring, realizes the straight reciprocating motion of magnetic piston, and magnetic piston drives power rail and externally exports the power of straight reciprocating motion.
The beneficial effects of the utility model are: this device adopts magnetic force to realize rotatablely moving and is converted to straight reciprocating motion, and a kind of brand-new movement conversion mode and transformational structure are provided, novel structure, simple; This mechanism does not connect the connecting rod of rotating moving part and straight reciprocating motion parts, and friction has not reduced failure rate; Because magnetic force untouchable can be realized non-contacting movement conversion and power transmission under two sealing freestanding environments, be particularly suitable in the particular surroundingss such as high pollution, poisonous, vacuum; Simultaneously owing to adopt the soft drive conversion of magnetic force, when magnetic piston hinders can't move the time for some reason, can not block the motion of runner, can effectively prevent the damage of power take-off mechanism; By the difference that magnet pitch is provided with, can realize that magnetic piston drives the fix straight reciprocating motion of frequency or frequency conversion rate of power rail.
Description of drawings
For ease of further describing, the utility model is described below in conjunction with accompanying drawing to of the present utility model:
The structure chart of Fig. 1 a kind of embodiment of the present utility model;
The structure chart of the another kind of embodiment of Fig. 2 the utility model.
Among the figure: 1 power rail; 2. spring; 3. magnetic piston; 4. guide cylinder; 5. magnet; 6. runner; 7. actuating unit rotating shaft.
Embodiment
