Variable speed driving mechanism with cylinder

Abstract

The invention discloses a variable speed driving mechanism with a cylinder. The variable speed driving mechanism aims at solving the problem that cylinders are hard to move in a variable speed mode in the prior art. The variable speed driving mechanism comprises a main cylinder and a frame which are fixed together; the variable speed driving mechanism also comprises a main sliding block, an auxiliary cylinder, an auxiliary sliding block, a connecting rod and an output sliding block; the main sliding block can move in a linear mode; the auxiliary cylinder is connected with the frame; the auxiliary sliding block can move in a linear mode; the output sliding block can move in a linear mode; the main cylinder and the auxiliary are connected with the main sliding block and the auxiliary sliding block respectively so as to drive the main sliding block and the auxiliary sliding block to move in a parallel linear reciprocating mode; the middle section of the connecting rod is hinged to the main sliding block; two sliding tables are arranged at two ends of the connecting rod respectively and are in sliding connection with strip holes formed in the auxiliary sliding block and the output sliding block respectively. The angle of the connecting rod can be changed through the simultaneous driving of the main cylinder and the auxiliary cylinder, the connecting rod is pushed by the sliding tables and the strip hole formed in the output sliding block to drive the output sliding block to move in a variable speed mode, and the output sliding block is used for driving the external structure to move. According to the variable speed driving mechanism with the cylinder, the different rates of motion output can be obtained through the adjustment of the motion frequency of the main cylinder and the auxiliary cylinder and accordingly the applicability is strong.

Description

technical field [0001] The invention relates to a device for adjusting the action speed of a cylinder. Background technique [0002] Cylinder is a commonly used driving device on the assembly line. It is often used to push or pull the workpiece. The typical working method of the cylinder is to move at a constant speed, but under certain working conditions, a specific speed change is required for the driving operation. The stroke of the existing cylinder Difficult to be retrofitted to work at variable speeds. Contents of the invention [0003] The present invention intends to provide a variable speed driving mechanism for a cylinder to solve the problem that the cylinder is difficult to change speed in the prior art. [0004] The cylinder variable speed drive mechanism in this program includes a fixed main cylinder and a frame, and is characterized in that it also includes a linearly movable main slider, an auxiliary cylinder connected to the frame, a linearly movable auxi...
