Description

A coaxial stacked multi-layer arbitrary angle rotation limiter

technical field

The invention relates to the technical field of mechanical equipment, in particular to a coaxially stacked multi-layer arbitrary angle rotation limiting device.

Background technique

In some rotary instruments and equipment, reliable control of the rotary angle and multi-angle control are often required for motion control and protection of equipment components. Although proximity switches and travel switches can realize angle control, they are unstable and unreliable. Therefore, the best way to reliably control the rotation angle is the control method of the mechanical structure; generally, a special rotation limit device is used to achieve reliable rotation angle control. However, according to the retrieval results, although the existing rotary limiting mechanism can realize reliable limiting, it cannot realize multi-angle or arbitrary angle limiting. For example: the patent No.: CN01240598.1 patent "360° azimuth limit mechanism of simulation turntable" design a kind of including left limit stop rod, right stop rod which is 30° azimuth with left stop rod, elastic stop Rod, two connecting plates and a stop plate form a limit mechanism, which can only make the simulation turntable rotate 180° clockwise or 180° counterclockwise within the range of 0°～360°. The patent number is: CN03212674.3 patent "an electromechanical 720-degree rotary limit mechanism" designed a limit mechanism mainly composed of a rotary part and a fixed part, which can make the rotary part relative to the fixed part at 0 ° ~ 720° range swivel. The above-mentioned limiting devices have complex structures, cannot realize arbitrary angle control, and have limited application ranges.

Contents of the invention

The purpose of the present invention is to provide a coaxially stacked multi-layer arbitrary-angle rotation limiting device to overcome the problems of the existing limiting device with complex structure, inability to realize arbitrary angle control, and limited application range.

In order to achieve the above purpose, the following technical solutions are adopted:

A coaxial stacked multi-layer rotary limit device at any angle, which consists of a rotary shaft, a follow-up dial ring, a limit stop ring and a machine base; the follow-up dial ring, limit stop ring and machine base are sequentially installed On the rotary shaft, the follow-up ring is fixedly connected with the rotary shaft, and the limit stop ring and the machine base are sleeved on the rotary shaft. The device includes at least one limit stop ring, and the limit stop ring close to the machine base follows the The machine base is fixedly connected, and an angular rotation limiting device is arranged between the follow-up dial ring and the limit stop ring, and between adjacent limit stop rings.

Wherein, an axially protruding toggle foot is provided on the outer ring of the follow-up dial ring; two protruding gear feet corresponding to the toggle foot are provided on the limit stop ring, Correspondingly, a toggle foot is provided; the toggle foot forms an angular rotation limiting device with the gear foot.

The outer ring of the follow-up ring is provided with two axially protruding gear feet; the limit stop ring is provided with protruding toggle feet corresponding to the gear feet, and the other side of the limit stop Correspondingly, there are two gear feet; the toggle foot and the gear foot form an angular rotation limiting device.

The beneficial effect of the present invention is that: when the rotary shaft rotates around one direction, it drives the fixed follow-up dial to rotate a corresponding angle through the angle rotation limiting device and the limit stop ring, and then the follow-up dial passes through the angle rotation limiter. The position device drives the next limit stop ring to rotate by a corresponding angle, so that it is transmitted to the last limit stop ring fixed with the machine base; the rotation angle of the rotary shaft in the whole process is passed through each adjacent pass angle rotation limit device The sum of the corresponding rotation angles of the accessories; adjusting the number of limit retaining rings and the rotation angle of the angle rotation limit device can adjust any rotation angle of the whole system in one direction; therefore, the present invention has simple structure, multi-angle limit, limit Flexible, easy to use, wide adaptability and so on.
