Background

With the continuous development of (numerical control) heavy roll lathes, the roll lathes are indispensable important production equipment for metallurgical enterprises, are mainly used for machining the roll pass, turning the excircle, the roll neck and the like of the roll, and the user needs to machine special parts in the roll industry due to the continuous improvement of the machining capacity of the machine tool, such as the machining requirements of machining two conical surfaces, a U-shaped groove and the like of the roll pass. Aiming at all common heavy horizontal roller lathe type machine tools in the current machining, the machining mode commonly used in the machining industry has the advantages of fixed structure, poor flexibility and incapability of meeting the machining requirement in actual use. The whole turning tool rest is an integral double-vertical-tool-plate frame type tool rest, the tool rest is moved by driving a ball screw to reciprocate through a transverse motor, the conventional machining requirements of turning an excircle, an end face, a groove and the like can be only completed, and the machining requirements of a taper and a conical surface are required to be completed through X, Z mutual linkage differential compensation of a numerical control system. Therefore, for a user to buy a numerical control roller machine tool, the purchase cost of the numerical control roller machine tool is increased, the market competitiveness is reduced, and the like.

Therefore, under the condition that the cost does not need to be increased too much on a common roller lathe, a novel special tool rest device for the roller lathe can be developed according to the special requirements of roller parts of users.

SUMMERY OF THE UTILITY MODEL

The utility model aims to improve the application scope of roll turning lathe turning, the novel special tool rest device for roll turning lathe that provides.

The technical scheme of the utility model: a novel special tool rest device for a roll lathe comprises a saddle, a ball screw pair, a sliding plate, a frame type tool rest body, a cutting board, a manual adjusting screw rod and a frame type tool rest turning device, wherein the saddle is installed and fixed on a lathe bed, the sliding plate which slides through a linear sliding mechanism is arranged on the saddle, the frame type tool rest body is installed on the sliding plate, the frame type tool rest body is of a box-shaped structure, the cutting board is fixed on two side surfaces of the frame type tool rest body through a locking pressing plate, the cutting board extends out and retracts through the rotation of the manual adjusting screw rod, and a tool is installed at the front end of the cutting board; frame tool holder body divides the three-layer, and the upper strata is frame tool holder body, and the centre is rotatable slewer, through worm gear manual regulation, and at 90 degrees direction rotations, the base has the millimeter graduation apparatus, and the knife rest lower floor is equipped with transverse drive's ball pair, and the left side is to having horizontal spacing combination travel switch, and the right side is to having vertical spacing combination travel switch.

The tool rest is lubricated by adopting a hydraulic oil supply structure.

The utility model has the advantages that: the device can meet the processing requirements of the taper and the conical surface of a special roll pass, and expands the application of a common roll lathe. The device has the characteristics of simple structure, convenience in adjustment, convenience and flexibility in operation, high reliability and the like, and ensures the processing requirements of workpieces.
