Abstract

The invention discloses a one-way rotating crank mechanism, and aims at solving the problem that a machine tool rotary motion mechanism in the prior art is incapable of realizing one-way motion. The one-way rotating crank mechanism comprises a frame, a driving wheel arranged on the frame, a driven shaft slidingly connected with the frame and a driven wheel fixed with the driven shaft, and also a crank and a gear connected with the driven shaft through a one-way bearing, wherein a plurality of hinging holes are formed in the crank, one end of the crank is hinged to the rim of the driving wheel, while the other end of the crank is hinged to an axially movable sliding rod, the two ends of the sliding rod are slidingly connected with the frame, a section of rack is arranged on the middle part of the sliding rod, and the rack is engaged with the gear. The one-way rotating crank mechanism is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of machine tool processing, in particular to a crank one-way rotation mechanism. Background technique [0002] The rotary motion mechanism is commonly used in the rotary table of the machine tool, and the slotted wheel mechanism is more commonly used in the rotary motion mechanism. However, in actual use, the slotted wheel mechanism still has some shortcomings. The stroke cannot be adjusted, and the rotation angle cannot be too small to realize One-way movement, the acceleration of the sheave when it starts and stops is large, and there is an impact, and it will intensify with the increase of the speed or the decrease of the number of grooves of the sheave, so it is not suitable for high-speed movement. Angular movement. Contents of the invention [0003] The present invention intends to provide a crank one-way rotary mechanism to solve the problem that the rotary motion mechanism of a machine tool in the...
