Prior art is owing to being to use general universal milling machine, adopt horizontal processing, lathe rigidity is inadequate, vibrates large feeding speed slow more than Ф 30mm in the processing of large specification cutter, the common screw rod transmission of workbench gap is too large, can only adopt upmilling processing, dividing head change gear drive line is oversize, and the error of division is large, grooved changes too greatly, labor strength is large, and withdrawing moves up and down and consumes a large amount of power by lifting platform, and workman can only single-set operation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of numerical control instrument production miller, and it is increased work efficiency and cutter quality.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of numerical control instrument production miller, it is characterized in that, it comprises ball screw, stepper motor, sleeping wheel, sleeping bar, sliding sleeve holder, sliding sleeve, unit head, shift handle, milling cutter, workbench, cross slid platform, dividing head, stepper motor is connected with one end of ball screw, sleeping bar is positioned on one end of sleeping wheel, sliding sleeve fixed seating is in a side of sleeping wheel, sliding sleeve is positioned at sliding sleeve holder, unit head and sliding sleeve are fixed, milling cutter is positioned at the bottom of unit head and is positioned at the side top of dividing head, shift handle is connected with unit head, workbench is between dividing head and cross slid platform, the other end of ball screw is connected with cross slid platform.
Positive progressive effect of the present utility model is.
Detailed description of the invention
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model numerical control instrument production miller comprises ball screw 1, stepper motor 2, sleeping wheel 3, sleeping bar 4, sliding sleeve holder 5, sliding sleeve 6, unit head 7, shift handle 8, milling cutter 9, workbench 10, cross slid platform 11, dividing head 12, stepper motor 2 is connected with one end of ball screw 1, sleeping bar 4 is positioned on one end of sleeping wheel 3, sliding sleeve holder 5 is positioned at a side of sleeping wheel 3, sliding sleeve 6 is positioned at sliding sleeve holder 5, unit head 7 is fixing with sliding sleeve 6, milling cutter 9 is positioned at the bottom of unit head 7 and is positioned at the side top of dividing head 12, shift handle 8 is connected with unit head 7, workbench 10 is between dividing head 12 and cross slid platform 11, the other end of ball screw 1 is connected with cross slid platform 11.The model of dividing head 12 can be model TX3.
Workpiece utilizes dividing head to adopt a top one folder mode, and clamping is very reliable, and due to climb cutting processing, when work, dividing head can be because Milling Force is too large and out of control.Cross slid platform and ball screw are direct-connected, add dividing head, three step motor control, can realize like this three-shaft linkage.
Unit head is fixed on sliding sleeve, and when the work of processing straight trough, unit head is vertical with workbench, unclamps sliding sleeve and rotate sleeping bar to drive sleeping wheel when processing helicla flute, and sleeping wheel is connected on sliding sleeve, in the time that sliding sleeve turns to the spiral angle of operation requirement, tightens sliding sleeve.Need to adjust workpiece anterior angle size time, unclamp unit head, rotate adjustment and move to appropriate location.When work, select suitable rotating speed by shift handle, start stepper motor rotary cross slide unit and be fed into operating position, workbench starts feed motion, when processing helicla flute, dividing head processes first groove by the rotation of helical pitch speed ratio, workpiece withdrawing, and workbench falls back on initial position, dividing head calibration rotation simultaneously, repeat to reprocess second groove, until completion is increased work efficiency and cutter quality like this.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect to solution of the present utility model further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
