Description

Technical Field

[0001] The utility model relates to the technical field of cam splitters, and more specifically, to a cam intermittent matching structure of a cam splitter. Background Technique

[0002] A cam splitter, also known as a cam indexing device or an intermittent splitter in engineering. It is a high-precision rotary device, and under the current requirements of automation, the cam splitter is particularly important. The cam splitter is a device that relies on the gapless fit between the cam and the needle roller (its meshing drive mode is similar to that of a worm and worm gear) and repeats the transmission operation along a predetermined cam curve. It inputs continuous rotational drive and outputs intermittent rotational, oscillating, or lifting actions. The cam splitter is mainly used in equipment such as automated processing, assembly, and inspection.

[0003] In the existing cam splitter, when working, the cam roller radially embedded on the circumferential surface of the turret makes linear contact with the tapered support rib of the cam on their corresponding inclined surfaces. After the cam roller and the cam work in meshing for a long time, the cam roller is easily damaged. And the traditional fixing method of the cam roller and the turntable is mostly by pressure fixing, that is, the cam roller is placed on the shaft or the cam disk, and then pressure is applied to make it closely fit with the shaft or the cam disk and is forcibly fixed by pressure. This brings a lot of inconvenience to the later replacement and disassembly of the cam roller. Therefore, there is a certain room for improvement in this device.

[0004] In view of this, research and improvement are carried out on the existing problems, and a cam intermittent matching structure of a cam splitter is provided, aiming to solve the problems and improve the practical value through this technology. Content of the Utility Model
