Jacking mechanism

Abstract

The invention discloses a jacking mechanism. The jacking mechanism comprises a carrier for carrying a workpiece and a plurality of pillars for supporting the carrier, wherein a sliding plate which can move horizontally is arranged below the carrier, and an arc-shaped groove is arranged on the sliding plate; the lower surface of the carrier is connected with a guide plate which is parallel to the sliding plate, and a guide column which extends into the arc-shaped groove is arranged on one surface facing the sliding plate on the guide plate; and when the sliding plate moves horizontally, the carrier can follow the guide column, and then the carrier and the guide column can be further driven by the arc-shaped groove on the sliding plate to make vertical motion. According to the jacking mechanism disclosed by the invention, the guide column is driven by the trajectory of the arc-shaped groove on the sliding plate to make the vertical motion, then the carrier can carry the workpiece to move up and down, the motion is smooth during jacking and descending processes, the acceleration of the jacking mechanism is particularly smaller during startup and stoppage, the vibration produced by the workpiece is reduced, the workpiece can be prevented from being affected by the motion of the jacking mechanism, the jacking mechanism can be always kept in a set positioning position, and then the operation of the workpiece can be prevented from being affected.

Description

technical field [0001] The invention relates to a jacking mechanism, which belongs to the technical field of machinery. Background technique [0002] During the production line operation, the workpiece transferred from the previous station needs to be processed at the current station. It is often necessary to use the jacking mechanism to lift the workpiece, and then perform the operation of the current process. After the current station operation is completed, it will be lifted The mechanism descends to make the workpiece return to the assembly line and transfer to the next station. Therefore, the jacking mechanism is used very frequently on the assembly line. However, the rising and falling movements of the jacking mechanism used in the prior art are relatively violent, especially the start-up stage is not smooth, and the sudden start-up action brings a large vibration to the workpiece supported by it, and the position of the workpiece will deviate due to the vibration , ...
