Technical part

The present invention relates to the technical field of machine tool devices, in particular to a reduction half-camshaft follower device.

technology in the background

Devices for machine tools that are automatically transported and transferred between the stations of the machining process with the mounted workpiece. The

Overtravel devices are mainly used in automatic assembly lines, machining centers, flexible manufacturing systems and other automated production equipment for less regular shapes that cannot be easily positioned, clamped and transported automatically. After the workpiece has been mounted and positioned on the tracking device, the tracking device is moved from the transport unit to the individual

stations transported. The trailing device usually comes with its base level and two

Positioning holes positioned on the machine tool and clamped by the clamping mechanism of the machine table, which ensures the relative position of the workpiece and the tool. If the workpiece is machined with high accuracy, the

Base level of the trailing device often in a positioning base level and a

Transport base level split to protect positioning base level accuracy.
