technical field

The utility model relates to mechanical processing equipment, in particular to a milling tool holder structure for pattern processing of ordinary lathes.

Background technique

When it is necessary to process the lentil-shaped multi-slot of a rod-shaped workpiece, the rod-shaped workpiece is relatively long and is not suitable for milling machine processing. Usually, the lathe chuck and the top of the tailstock are used to clamp the main workpiece, and the small tool rest is driven by the screw. The reciprocating motion of the cutting tool is used for processing, because a lentil-shaped notch needs multiple cuttings to complete, so the processing efficiency is low, and the processing accuracy is difficult to ensure consistency due to the technical level of the processing personnel.

Contents of the invention

The purpose of this utility model is to propose a milling cutter holder structure for pattern processing of ordinary lathes. By setting a milling cutter holder on the tool holder supporting plate of the lathe, a milling cutter holder is installed on the milling cutter holder according to the lentil-shaped multi-notches. The once-formed milling cutter realizes the processing of longitudinal lentil-shaped multi-slots of long rod-shaped workpieces by ordinary lathes.

In order to achieve the above object, the technical solution of the present utility model is: a milling tool holder structure for pattern processing of ordinary lathes, including a lathe tool holder feeding tray, wherein a The milling cutter holder is provided with a vertical panel perpendicular to the feed tray, the vertical panel is rotatably arranged on the milling cutter holder, the plane of the vertical panel is parallel to the axis of the lathe, and the vertical panel is fixed on the vertical panel. A milling cutter driving device, the milling cutter driving device includes a gear box, a main shaft and a driving motor, the main shaft is parallel to the plane of the facade panel, the driving motor is connected to the gear box, the gear box drives the main shaft to rotate, and a forming milling machine is arranged on the main shaft Knife.

The solution is further as follows: on the vertical panel of the milling cutter holder, an annular T-shaped groove for fixing the milling cutter driving device is arranged around the center of the vertical panel, and the milling cutter driving device is fixed in the annular T-shaped groove by bolts, Also be provided with worm gear angle adjusting device on described milling cutter frame, the worm gear of worm gear angle adjusting device is fixed on the facade panel of described milling cutter frame, and the worm screw of worm gear angle adjusting device is fixed on described tool rest feed On the tray, the worm drives the vertical panel of the milling cutter holder to rotate and then drives the milling cutter driving device to rotate, so as to realize the radial groove milling or axial or different angle milling grooves of the formed milling cutter on the processed parts.

The solution is further as follows: the profiled milling cutter includes a milling cutter bushing and a milling blade, a milling blade slot is arranged around the outer circumference of the milling cutter shaft sleeve, and the milling blade is embedded in the slot.

The solution further is: the milling insert is a symmetrical double-edged structure, which can be used interchangeably.

The beneficial effects of the utility model are:

The structure is reasonable and the operation is simple, which realizes the processing of long rod-shaped workpieces with vertical and horizontal bean-shaped multi-slots by ordinary lathes. The symmetrical double-edged structure of the milling blade can be exchanged and used, saving the cost of tool replacement.

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
