Technical Field

The invention belongs to the technical field of lacquer-free wood door processing, and particularly relates to numerical control equipment capable of automatically finishing mirror image processing.

Background

The main structure of the paint-free wood door is that a main body frame is made of wood, two surfaces of the paint-free wood door are attached to density fiber boards (an A board and a B board) to make surfaces, various shapes are carved on the surfaces of the density fiber boards, and the A board and the B board are identical and symmetrical in shape. At present, the traditional processing technology of the lacquer-free wood door is to use a computer to manufacture an A board graphic cutter path, then introduce numerical control equipment to make an A board graphic, and remove the board surface after the processing is finished; and then, re-clamping the B plate, manufacturing a B plate graphic cutter path in a mirror image relationship with the A plate by a computer, and then introducing numerical control equipment to process and manufacture a B plate graphic. Because the graphs of the A plate and the B plate are in a symmetrical relation, a mirror image graph needs to be made again, the graphs of the A plate and the B plate are not consistent easily by adopting the conventional numerical control equipment, the rejection rate is high, and the processing cost loss is caused; and only one plate is processed each time, the working efficiency is also lower.

The patent application number CN201710644693.1 discloses a numerical control double-position engraving machine, wherein, a station provided with two symmetrical spindle motors provides power by utilizing a Y-axis motor and a bidirectional screw rod, so that the two spindle motors are in mirror symmetry along the Y-direction movement track, thereby realizing double-sided engraving of workpieces at one time, combining a pair of workpieces back to back together, and achieving the effect of double-sided engraving.

(2) although the equipment is also provided with a tool magazine, automatic double-sided tool changing cannot be realized, tool changing operation is very troublesome, and manual double-sided tool changing can cause that the tool types of the double-sided tool changing are inconsistent, namely, the tools are changed by mistake; the equipment is only suitable for simple pattern carving, and if complex patterns are carved, frequent tool changing is needed, so that the working efficiency is low. In the frequent tool changing process, the machine head is possibly triggered to move, and the consistency of the mirror image of the pattern is influenced;

(3) according to the equipment, a forward-reverse rotation Y-axis screw rod respectively drags a left spindle motor and a right spindle motor to move in opposite directions or move in opposite directions at the same time, the screw rod generates a large error after being worn after long-term use, and the paths are easy to be inconsistent when the two motors move, so that the carved patterns are inconsistent;

(4) the engraver head rotates at a high speed when engraving, generates vibration, can make the motor produce displacement deviation at the lead screw, also leads to carving the pattern inconsistent. In addition, the two boards are positioned respectively and can be infirm under the influence of vibration, so that the boards slightly displace, the deviation of the carved patterns is caused, and the rejection rate is high.

Four, prior art's two aircraft nose engravers also are provided with the tool magazine, but can not realize automatic two-sided tool changing, tool changing operation is very troublesome, artifical two-sided tool changing, it is inconsistent to cause the sword type of two-sided tool changing possibly, change wrong sword promptly, only be applicable to simple pattern sculpture, if complicated pattern sculpture, then need frequent tool changing, work efficiency is low, and at frequent tool changing in-process probably touch the aircraft nose and take place the displacement, influence pattern mirror image uniformity. The double-head engraving machine can automatically rotate to change tools, is convenient to operate and high in tool changing efficiency, the side wall of the disc cover is provided with the visual hole, the tool changing state can be manually monitored, tool changing errors can be further prevented, the effect of changing tools for multiple times is better, and the situation that the machine head is touched to move due to manual tool changing is avoided.

Fifthly, the disc cover can protect the tools in the tool magazine from being damaged during moving, loading, unloading and carving, and the side wall is provided with a visual hole, so that monitoring, overhauling and timely replacement of passivated tools are facilitated.

Sixthly, the tool magazine of the engraving machine is arranged on two sides of the Z-axis vertical plate, and during engraving, the tool magazine arm and the Z-axis vertical plate form an included angle of 150 degrees, so that the machine head assembly is damped, path displacement caused by engraving vibration is prevented, and the wood plate is prevented from being broken due to vibration.

Seventhly, in the prior art, Y-axis motors are arranged at two ends of a screw rod and do not move along with a carving machine head, the arrangement enables the Y-axis motors to drive the machine head at a far position to move in a mirror image mode through screw rod transmission, and errors tend to exist in the displacement of the Y-axis motors; the motor of the engraving machine moves along with the machine heads, and the movement and the displacement of the two machine heads are controlled more flexibly and accurately.

The motor assembly structure of the engraving machine is simple, and the motor can be installed by using two vertical plates and one horizontal plate, so that the engraving machine is more economical and practical.

The engraving machine can realize more accurate and stable positioning under the condition of saving the material grabbing suction cups, the feeding positioning table and the discharging table, ensures that the wood board is not moved, is more convenient to place and take out, does not need to operate the material grabbing suction cups, the feeding positioning table and the discharging table in the front and at the back, and saves time cost and equipment manufacturing cost.

Compared with single-head carving, the working efficiency is improved by more than one time, and the comprehensive carving precision can be improved by more than 30%. Compare in current duplex head sculpture, work efficiency improves more than 20% (mainly at tool changing efficiency), effectively avoids the tool changing mistake, synthesizes the sculpture precision and can improve more than 20%, and the pattern mirror image sculpture qualification rate is more than 98%.
