Special machine tool for pattern roll lentil groove processing

Abstract

The invention discloses a special machine tool for machining a pattern roller lentil-shaped groove, and aims to provide a special machine tool in the field of metallurgical machining. The machine tool is provided with a frame module, a positioning and clamping device, a power head milling device and a feed indexing device; and the positioning and clamping device, the power head milling device and the feed indexing device are all arranged on the frame module. The whole structure of the machine tool adopts a gantry vertical milling machine layout; the rigidity of a machining process system is good; the workpiece positioning and clamping are realized by using a support roller and V-shaped block combined effect; a roller is fast in rotation and reliable in clamping; the workpiece maneuvering clamping and loosening are realized by using a hydraulic cylinder to achieve the effects of labor saving and fastness; a servo motor is adopted to provide power for peripheral indexing of the roller and positioning of a multi-station feeding position; the indexing and positioning precision is high; the automatic workpiece machining can be realized through electric control; and the machine tool is used for machining workpieces, low in vibration, few in surface vibration patterns, high in machining quality, simple in structure, convenient for maintenance and low in equipment investment.

Description

technical field [0001] The invention relates to mechanical equipment in the field of mechanical processing, in particular to a special machine tool for processing lentil-shaped grooves of patterned rolls. Background technique [0002] Patterned rolls are used for rolling anti-skid steel plates, and the roll surface needs to be processed with neatly arranged lentil-shaped grooves. It is staggered at 90° and arranged in staggered teeth in the axial direction of the roll. The bean-shaped groove is generally processed by a disc milling cutter, but it is difficult to process because of the difficulty in adjusting the relative position of the workpiece and the tool. At present, special-purpose machine tools are mainly used for the processing of patterned rolls in China. There are two technical solutions: one is to use a hobbing machine for transformation, and the other is to use a horizontal car for transformation.

Problems solved by technology

[0002] Patterned rolls are used for rolling anti-skid steel plates, and the roll surface needs to be processed with neatly arranged lentil-shaped grooves. It is staggered at 90° and arranged in staggered teeth in the axial direction of the roll. Lentil-shaped grooves are generally processed by disc milling cutters, but due to the difficulty in adjusting the relative positions of the workpiece and the cutter, the processing is more difficult.

At present, special-purpose machine tools are mainly used for the processing of patterned rolls in China. There are two technical solutions: one is to use a hobbing machine for transformation, and the other is to use a horizontal car for transformation. The investment cost of using a hobbing machine to transform into a special machine tool is high, and the horizontal car is used for transformation. Because the middle carriage needs to be extended forward to feed the tool, the forward extension distance is too long, the processing stability is poor, vibration is easy to occur, and the processing quality is unstable.
