Abstract

A technology capable of automatically correcting pattern positions and applied to a quadrilateral gauge square saw relates to the technical field of wood door machining industries. A correction cutting method includes the following steps of (1) door core frame measurement, (2) panel image position determination, (3) outline contrast calculation, (4) mechanical correcting and (5) mechanical cutting. By means of the technology, the position of a door blank on a machine tool working table can be adjusted automatically before saw cutting, patterns on a panel are symmetrical in center line, and the door core framework and the panel are level after gauge square saw cutting is conducted.

Description

Be applied to the technology that can automatically correct pattern position of four limit rule side saws

Technical field:

The present invention relates to timber processing industry technical field, be specifically related to a kind of technology that can automatically correct pattern position that is applied to four limit rule side saws.

Background technology:

In the production process of door, first, with a door core framework of timber composition, on framework, paste again figuratum panel, because framework and panel all do not have accurate benchmark, so can not being attached on a center line of core framework panel decorative pattern symmetry.In next step rule side's sawing operation, ensure being of the required size of door, the decorative pattern that ensures panel is symmetrical on center line, also will ensure that a core framework flushes with panel, makes automatic sawing, cutting be difficult to realize, the artificial adjustment of basic employing in the industry at present, the method for proofreading and correct, not only waste time and energy, and can not ensure the staying on a center line of core framework of panel decorative pattern full symmetric to affect production efficiency, workpiece yield rate is low, cannot carry out automatic streamline and produce.

Summary of the invention:

The object of this invention is to provide a kind of technology that can automatically correct pattern position that is applied to four limit rule side saws, it can be before sawing the position of pitch embryo on platen automatically, make after its side's of rule sawing, both the decorative pattern that had ensured panel is symmetrical on center line, also ensures that door core framework flushes with panel.

In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its correction cutting method is: 1, door core framework is measured: the outline data of the core framework of must going out; 2, panel picture position is determined: manually do specific reflective marker in panel pattern characteristics position, sensor scans workpiece on mechanical numerical control device, draws the position coordinates of panel pattern; 3, silhouette contrast is calculated: compare calculating by software opposite house core frame profiles data and panel pattern position coordinate, draw mechanical checkout desired data; 4, mechanical checkout: by the processing to profile comparison data, workpiece blank is carried out to mechanical checkout; 5, machine cuts.

The present invention can be before sawing the position of pitch embryo on platen automatically, make after its side's of rule sawing, both ensured that the decorative pattern of panel was symmetrical on center line, also ensure that a door core framework flushes with panel.

Detailed description of the invention:

With reference to Fig. 1-Fig. 4, this detailed description of the invention by the following technical solutions: its concrete correction cutting method is: the preparation of a, panel: make the reflective marker that laser sensor can be responded at the Si Jiaochu of panel; B, door core framework are measured: on a side of door core framework, carry out multimetering by numerical control servo axle and draw its profile; C, panel picture position are determined: after panel is covered on a core framework, scan by laser sensor counter plate, the software computing technique in fuselage controller can calculate according to the gauge point at four jiaos of places of panel the profile of decoration panel; D, silhouette contrast are calculated: obtain core framework surface outline and a surperficial mutation by laser sensor technology; Compare calculating by software opposite house core frame profiles data and panel pattern position coordinate, draw mechanical checkout desired data; E, mechanical checkout: profile comparison data are processed, and fuselage controller sends adjusts signal driver machinery adjusting device, as numerical control axis servomotor, cylinder etc. are proofreaied and correct workpiece blank; F, machine cuts: workpiece blank cuts according to the shape of door core framework by four limit rule side saws after proofreading and correct.

This detailed description of the invention realizes by laser sensor technology, more convenient and quicker, and precision is high, is easy to realize.

This detailed description of the invention can be before sawing the position of pitch embryo on platen automatically, make after its side's of rule sawing, both ensured that the decorative pattern of panel was symmetrical on center line, also ensure that a door core framework flushes with panel.

Claims
