Novel integrated randomly-speed variable linear movement mechanism

Abstract

The invention discloses a novel integrated randomly-speed variable linear movement mechanism. A frequency variable motor consists of a pedestal, a frequency variable coil winding, a rotor, a bearing and a hollow shaft, wherein the outer circle, positioned in the pedestal, of the hollow shaft is fixedly provided with the rotor; the hollow shaft is arranged on the upper surface of the pedestal by the bearing; the hollow inner circle of the hollow shaft is provided with internal threads of corresponding specification; the outer circle of a screw rod is provided with external threads of the same specification as the hollow inner circle of the hollow shaft; the screw rod is screwed into the internal threads of the hollow shaft by the external threads on the screw rod; the outer circle of the screw rod is provided with a sliding groove parallel to the axis of the outer circle; a hole with a shape similar to that of the section of the screw rod is reserved in the center of a check plate; a protruded standstill locking bolt of the check plate is clamped in the sliding groove of the screw rod to form slide fit; and the check plate is fixedly arranged at one end of the pedestal by a bolt.

Description

technical field [0001] The invention relates to an integrated arbitrary variable speed linear motion mechanism, in particular to a novel integrated arbitrary variable speed linear motion mechanism. It belongs to the technical field of mechanical transmission. Background technique [0002] In the field of mechanical manufacturing and mechanical transmission technology, linear motion mechanisms are often used. At present, mechanical, pneumatic or hydraulic methods are mainly used to realize linear motion mechanisms. The mechanical method generally needs to go through the gear transmission mechanism, the crank connecting rod mechanism or the rack and pinion mechanism. The pneumatic or hydraulic method requires not only the actuator cylinder or hydraulic cylinder, but also a stable air or hydraulic source. In addition, in order to To implement the above-mentioned linear motion mechanism, it is necessary to add a corresponding electrical control system. Therefore, there are defe...

Problems solved by technology

The mechanical method generally needs to go through the gear transmission mechanism, the crank connecting rod mechanism or the rack and pinion mechanism. The pneumatic or hydraulic method requires not only the actuator cylinder or hydraulic cylinder, but also a stable air or hydraulic source. In addition, in order to To implement the above-mentioned linear motion mechanism, it is necessary to add a corresponding electrical control system. Therefore, there are defects such as complex structural system, large volume, high cost, and high failure rate. Due to the above-mentioned defects, there are still Defects with a low degree of automation control, not suitable for use in mechanical systems with a high degree of automation control
