Problems solved by technology
The cam sleeve is in close contact with the surface of the camshaft. When the concave wheel drives the cam to rotate, the camshaft also rotates synchronously. Therefore, the transmission between the camshaft and the cam sleeve relies on frictional force, which consumes a lot of power, and it is easy to have a rotation difference with the concave wheel. And then affect the smooth progress of the rolling groove

Embodiment Construction
[0018] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0019] Such as figure 1 , figure 2 and image 3 As shown, the cam for the cylindrical rolling type grooving machine is installed on the grooving machine through the cam shaft, and specifically includes a cam sleeve 1, the outer periphery of the cam sleeve 1 is provided with a rolling groove pressing table 2, and the cam sleeve 1 and the The rolling groove pressing table 2 is an integral structure, and the rolling gro...

The invention discloses a columnar rolling type channeling machine cam. The columnar rolling type channeling machine cam comprises a cam sleeve. The periphery of the cam sleeve is provided with a slotrolling pressing platen. At least one bearing is sleeved with the cam sleeve. The outer sides of the bearings are provided with bearing retainer rings, and the bearing retainer rings are installed inthe cam sleeve in a limitation manner. Each bearing comprises an inner bearing body, wherein the periphery of the inner bearing body is sleeved with an outer bearing body, and pin rollers are distributed between the inner bearing body and the outer bearing body in a limitation manner. According to the columnar rolling type channeling machine cam, the cam sleeve is internally provided with the bearings, connection of the cam sleeve and a cam shaft is achieved through the bearings, when a concave wheel cooperates with friction force to drive a pipe fitting and the cam to synchronously rotate, due to the existing of the bearings, the friction force is not needed any more to drive the cam shaft to synchronously rotate, synchronous rotating of the cam sleeve and the slot rolling pressing platen can be achieved, rolling ring slots are formed in the surface of the pipe fitting, the power consumption is small, the synchronism of the cam and the concave wheel is improved, the phenomenon that the rolling ring groove is nonstandard due to the rotating speed difference is avoided, and the defective rate is reduced.
Description
technical field [0001] The invention relates to the technical field of components for grooving machines, in particular to a cam for cylindrical rolling grooving machines. Background technique [0002] The cam is one of the important components to complete the grooving process on the grooving machine. When rolling the groove, the cam and the concave wheel cooperate to clamp the pipe fitting. Driven by the power part, the concave wheel rotates. Through the friction between the concave wheel and the cam and the pipe fitting, the pipe fitting and the cam are driven to rotate synchronously to complete the pipe fitting. roll groove. The currently used cam has a one-piece structure, that is, it includes a cam sleeve for being sleeved on the camshaft, and a raised ring platform for rolling pipe fittings is formed on the outer surface of the cam sleeve. The cam sleeve is in close contact with the surface of the camshaft. When the concave wheel drives the cam to rotate, the camshaft...
