Embodiment Construction
[0026] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0027] The function of the ejection mechanism is to hang, carry, and eject the load. The ejection mechanism needs to softly connect and limit the position of the load, control the offset of the load, and avoid the phenomenon that the load slips away from the ejection mechanism. At present, conventional ejection mechanisms for large-thrust linear motors cannot meet the high-efficiency and continu...

The invention discloses a high-linearity ejection device suitable for a high-thrust linear motor, which belongs to the field of power devices and comprises a suspension bracket, a rotor adapter, a connecting mechanism, a transverse limiting mechanism and a longitudinal rolling mechanism. The suspension bracket is used for bearing loads; a positioning boss is arranged at the position, correspondingto the rear side of the suspension bracket, of the rotor adapter; the rotor adapter is fixedly mounted on the rotor through a connecting mechanism; the transverse limiting mechanism and the longitudinal rolling mechanism are arranged on the suspension bracket; a guide rail is arranged on the rotor adapter, the transverse limiting mechanism is in transition fit with the side face of the guide rail, the guide rail transversely limits the transverse limiting mechanism, the longitudinal rolling mechanism makes contact with the bottom face of the guide rail, and the longitudinal rolling mechanismrolls with the bottom face of the guide rail as the supporting face. The ejection mechanism can bear large thrust of the linear motor, structural deformation generated by the large thrust is effectively controlled, the overall rigidity of the ejection mechanism is improved, smooth linear separation of a load and a rotor in the ejection throwing process is achieved, and frictional resistance in theseparation process is reduced.
Description
technical field [0001] The invention belongs to the field of power devices and relates to a high-linearity ejection device adapted to a large-thrust linear motor. Background technique [0002] A linear motor is a power device that directly converts electrical energy into mechanical energy for linear motion, and the mover runs at high speed under the thrust of the stator. Since it does not require an intermediate transmission mechanism, and does not require traditional power sources such as gunpowder and high-pressure gas sources, it can realize efficient and high-speed ejection of loads. At present, linear motors have been widely used in industrial fields such as rail transportation, industrial control, and CNC machine tools. [0003] The function of the ejection mechanism is to hang, carry, and eject the load. The ejection mechanism needs to softly connect and limit the position of the load, control the offset of the load, and avoid the phenomenon that the load slips away f...
