Multi-position load-bearing telescopic mechanism

Abstract

The invention discloses a multi-position load-bearing telescopic mechanism. The multi-position load-bearing telescopic mechanism comprises a machine frame, two linear guide rails, a cylinder a, a cylinder b, a cylinder connecting block and a connecting block. The two linear guide rails are fixedly installed on two sides of the machine frame respectively, every linear guide rail is internally provided with a linear slideway, sliding block ends are installed on the two linear slideways respectively, part of every sliding block end is located in the linear guide rails, another part of every sliding block end is located outside the linear guide rails, the tail end of a cylinder body of the cylinder a and an extending-out rod end of the cylinder b are installed in a series connection through the cylinder connecting block, an extending-out rod end of the cylinder a is connected with the sliding block ends of the two linear guide rails through the connecting block, and a cylinder body of the cylinder b is fixedly connected with the machine frame. Rapid stretching of the guide rails at fixed positions is achieved pneumatically on the premise that large loads are borne in every direction.

Description

technical field

[0001] The invention relates to a telescopic mechanism, in particular to a telescopic mechanism capable of bearing multi-directional heavy loads. Background technique

[0002] When it is necessary to move objects at a fixed position in daily production and daily life, the direct drive of the cylinder is generally used. However, because there is a certain gap between the piston rod and the cylinder body of the cylinder, it can generally only bear the tensile pressure from the axial direction, and the other directions do not. It has a large carrying capacity. When it is necessary to carry loads in multiple directions in the industry, T-shaped or dovetail-shaped linear slideways are generally used, and at the same time combined with driving parts such as motors to achieve linear motion. High rigidity, high precision linear telescopic movement. However, since the motor itself is a rotary motion, which is converted into a linear motion of the drive guide rail, i...
