Adjustment and feed movement control device for tool opening of non-fastening-shaft rotating cutter

Abstract

The invention relates to a numerical control machine, in particular to an adjusting and feed control device for a manway of a spindle-free veneer lathe, which includes a knife rest body, a pressure bar roller, a pressure bar frame and an adjusting bolt; the invention is characterized in that two lead rails are arranged on the knife rest body; the lead rails are provided with the pressure bar frame matched with the lead rails; one end of the pressure bar frame is provided with the pressure bar roll; the other end is provided with a screw rod; the screw rod is engaged with a worm wheel in a worm wheel box; a worm is connected with a servo motor; the pressure bar frame of the invention is arranged in the incline lead rails at the two ends of the knife rest body; the worm in the worm wheel box is driven by the servo motor to drive the worm wheel to rotate; the worm wheel then drives the screw rod to rotate; the size of the manway is manually changed by a nut and the adjusting bolt; a control system controls the servo motor to move according to a changed value after being changed; two plate thicknesses are arranged in an operation system, namely having two corresponding manway values; the installation of the plate thickness is changed, the manway changes correspondingly; the manway is convenient, shortcut and accurate to be adjusted; the assisting time is greatly shortened; therebyproviding reliable guarantee for the large scale continuous production of man-made boards.

Description

Technical field: [0001] The invention relates to a numerically controlled machine tool, in particular to a knife door adjustment and feed control device for a rotary cutter without a card shaft. Background technique: [0002] We know that the existing numerical control shaft-free rotary cutting machine is just that the feed system is servo-controlled and the adjustment of the pressure ruler (knife door) is still manually adjusted. The knife door adjustment device consists of a pressure ruler roller, a pressure ruler frame and It consists of adjusting bolts, which are used to adjust the position of the pressure gauge frame and the pressure gauge roller. After adjustment, the bolts are locked manually. The more advanced ones also use the oil cylinder to drag the pressure gauge roller forward and backward. Only one value of the knife door can be adjusted, and the size changes. It needs to be readjusted, and it needs to be readjusted after changing the thickness of the board. In...

[0002] We know that the existing numerical control shaft-free rotary cutting machine is just that the feed system is servo-controlled and the adjustment of the pressure ruler (knife door) is still manually adjusted. The knife door adjustment device consists of a pressure ruler roller, a pressure ruler frame and It consists of adjusting bolts, which are used to adjust the position of the pressure gauge frame and the pressure gauge roller. After adjustment, the bolts are locked manually. The more advanced ones also use the oil cylinder to drag the pressure gauge roller forward and backward. Only one value of the knife door can be adjusted, and the size changes. It needs to be readjusted, and it needs to be readjusted after changing the thickness of the board. In addition, the existing technology cannot automatically adjust the knife door according to the quality of the wood to meet the requirements of processing the surface board and core board. It cannot be rotary cut continuously, and it takes time and effort to work , the work efficiency is low, and it cannot meet the requirements of modern large-scale continuous and efficient production
