Abstract

The invention discloses a rotary stepper mechanism, which solves the problem that the rotation angle of the rotary stepper mechanism is unlikely to be adjusted in the prior art. The rotary stepper mechanism comprises a crank and a driven wheel, wherein a first connecting rod and a second connecting rod are arranged between the crank and the driven wheel, one end of the first connecting rod is hinged with one end of the crank, and the other end of the first connecting rod is hinged with one end of the second connecting rod; one end of the second connecting rod far away from the first connecting rod and the driven wheel coaxially rotate, ratchets are arranged at the edge of the driven wheel, detents engaged with the ratchets are arranged on the second connecting rod, and a plurality of hinged holes are formed in the crank. The rotary stepper mechanism is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a rotary stepping mechanism. Background technique [0002] The rotary motion mechanism is commonly used in the rotary table of the machine tool. The slotted wheel mechanism is more commonly used in the rotary motion mechanism. However, in actual use, the slotted wheel mechanism still has the following shortcomings: The acceleration when starting and stopping is large, there is impact, and it is intensified 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, and it is mostly used to realize the indexing movement that does not need to adjust the indexing angle frequently. Contents of the invention [0003] The present invention intends to provide a rotary stepping mechanism to solve the problem in the prior art that the rotation angle of the rotary stepping mechanism is difficult to adjust. ...
