The numerical control machining center usually comprises a machine table, and a control panel, a clamping and positioning mechanism, a gantry machining center and the like which are arranged on the machine table, although the existing numerical control machining center can ensure the completion of machining, the clamping and positioning mechanism is usually only clamped in the middle of a workpiece to be machined, for some workpieces to be machined with longer lengths, only the middle of the workpiece to be machined is clamped to be unstable, and the machining precision is influenced due to the fact that the workpieces to be machined are likely to deviate during machining.
Secondly, the gantry machining center is a machining center with a main shaft axis perpendicular to a workbench, the whole structure is a gantry frame and comprises double columns and a top beam, the middle part is also provided with a cross beam, the gantry machining center is particularly suitable for machining large-sized workpieces and workpieces with complex shapes, and the gantry machining center is provided with a fixed beam type (the cross beam is fixed, the workbench moves/rotates), a movable beam type (the cross beam moves up and down and the workbench moves back and forth), a movable column type (the workbench is fixed and the gantry frame moves), a crown block type (the workbench is fixed and the cross beam moves), and various gantry machining centers in the above composite forms, and the machining characteristics, the machining capabilities and the aimed product machining purposes are not completely the same. The current longmen machining center leads to it to receive external disturbance when adding man-hour owing to lack the protection to whole portal frame, simultaneously, is difficult to guarantee staff's personal safety, leads to the safe operation of unable assurance processing to and, it only possesses biax coordinated type structure usually, can't satisfy the demand to more processing positions, lacks the structural design who loads the cutter, leads to the change of cutter and settles inconveniently.
And, present numerical control machining center's control panel is mostly fixed on machining center, has to use a great deal of problem such as inconvenient, also has not few machining center to carry out certain improvement, mostly for installing a hinge point in the lathe bottom, through L type pole connection control panel, makes it reach mobilizable operation. Both of these mounting methods have certain drawbacks: the fixed control panel has a large defect, a general machining center is provided with at least two windows, namely a clamping window and an observation window, the fixed panel position increases the number of machine tool operators, and the operators cannot observe in real time when using the control panel to adjust the machining center, so that the operation is inconvenient. If one person controls the control panel, one person carries out clamping and piece taking work, and the personnel controlling the control panel can bring improper operation due to the visual field blind area, so that personal injury is caused to the clamping personnel. Although the movable panel is improved, the panel of the movable panel takes a hinge point as a center, one side of the L-shaped rod rotates in a circular arc shape with a radius, and the starting point and the end point are positioned in two operation windows.
Therefore, a new technology needs to be developed to solve the above problems.
