In order to adapt to the processing technology, the method in the prior art is to refit the vertical woodworking band saw, add a rotating shaft to the band saw, and control the angle of the winding shaft to change through a motor and a screw rod. However, the defects are that the angle and the processing thickness cannot be quickly and accurately adjusted, the woodworking band saw is limited by the application of the woodworking band saw, and the materials with the width of 1000mm cannot be beveled after refitting. Because the degree of automation of repacking is lower, can't cooperate the conveyer belt to carry out continuous processing, relies on artifical hand push pay-off completely, factor of safety is low, and machining efficiency is low, and processing roughness is big.

By adopting a new structure, a new process and a new idea, the high-yield integration is realized. Of course, the large-stroke quick-variable-angle electromechanical combination can be used for stably and efficiently processing, and has higher requirements on the processing and assembly processes of parts, and particularly, the parallelism of two important lead screws and the assembly of the band saw mechanism can reach the design precision.

The numerical control angle saw device provided by the embodiment of the utility model is characterized in that the double explosion-proof motors respectively drive the band saw wheels at the two ends to enable the band saw blade to continuously run in a single direction. The band saw blade is used as a cutting mode main body and has an absolute position relation with a band saw beam.

Because of the limited controllable conditions of the band saw blade, the numerical control angle saw motion scheme is used for carrying out parameterized control expansion on the band saw beam. Through model comparison, theoretical derivation and a large number of MCD off-line simulation, an optimal function equation set calculation path is found. The design rule is that the theoretical stroke of the lifting screw rod is deduced by taking the horizontal projection distance between the two crossed roller bearings as a fixed value according to the angle parameter and the height parameter, and the error is compensated. The latest model multi-axis control system is adopted for secondary development, and the latest generation of servo motor is matched, so that the positioning accuracy is high and the power-off position is recorded reliably due to the adoption of an absolute value encoder. The electrical constitution is updated and updated rapidly and iteratively to promote the optimization development of the mechanical structure, so that the whole system is more reasonable, safer and more efficient.

The operation logic of the data miter saw device provided by the embodiment of the utility model is as follows:

the angle is adjusted for the past time, and the control system executes actions according to internal logic. And pressing a start button, driving the screw rods to synchronously move by the two lifting servo motors to lift the whole band saw mechanism to the mechanical origin position of the first band saw wheel, and then controlling the saw group to independently move downwards around the first crossed roller bearing to return to the other mechanical origin by the first lifting servo motor so as to restore the band saw blade to the initial horizontal state. And after the calculation of the internal expression, the control system sends out instructions to execute, the first crossed roller bearing is a fixed center point, and the second lifting servo motor drives the saw group to move upwards for a specified distance. The angle between the projection of the connecting line of the central points of the two crossed roller bearings and the table top is the required angle. The second crossed roller bearing is lifted along with the lifting screw rod, and the length of the second crossed roller bearing changes according to a sine curve, so that the second crossed roller bearing is assembled on the rotating shaft part, and the rotating shaft part dynamically moves through the linear guide rail sliding block to meet the stability requirement. Finally, triggering the internal instruction of the coupling shaft to enable the band saw mechanism to synchronously move downwards to the distance from the table top to finish the adjustment preparation work of the band saw.

When the machine tool normally operates, a cylinder with required machining width is opened, the punching suction belt is used for sucking a workpiece to be machined to automatically feed forward along the guiding rule, and when the band saw mechanism is used for cutting, part of waste with damaged surface is cleaned by the three suction inlets and the other part of waste is cleaned to the waste discharge collecting inlet by the hairbrush of the waste discharge mechanism.

The processed workpiece is sent to the next working procedure by a conveyor belt.
