Description
Technical field
The present invention relates to a kind of machining machine and tool, particularly relates to a kind of numerical value control tool machine fourth shaft rotary disk device that can effectively promote bearing torque and saving manufacturing cost.
Background technology
General Numerical Control (NC) toolroom machine has three direction of principal axis such as X, Y, Z usually and makes linearly moving function; cutter utilizes above-mentioned three moving; can arrive the location point that workpiece wants to cut accurately and carry out stock removal action; yet; above-mentioned three direction of principal axis are owing to can only make linearly moving relation; can't make the cooked mode of circumference angle to workpiece; therefore can installing one on the NC toolroom machine usually again, to be commonly called as be the 4th rotary disk device, can generally rotate the cutting operation of processing (for example calibration, fillet or peripheral curved) whereby to workpiece.
See also shown in Figure 1, the 4th general rotary disk device 10 includes an active cell 11 and a driven unit 12, this active cell 11 mainly has a driving shaft 111 and a gear hobbing cam 112 that is arranged on the driving shaft 111 constitutes, these driving shaft 111 outer ends are connected with a motor (figure do not show) with as drive source, be concaved with one section threaded portion 121 on this gear hobbing cam 112 with predetermined pitch, this driven unit 12 mainly has a driven shaft 121 and connection and is arranged on driving-disc 122 on the driven shaft 121, this driven shaft 121 is to be the perpendicular quadrature shape with driving shaft 111, driven shaft 121 extends to outboard end and is connected with one and can makes the rotary disk (figure does not show) install and fix to workpiece, this driving-disc 122 is to be the one interlock with driven shaft 121, its periphery annular arrangement is provided with most rollers 1221 rotationally, roller 1221 is just engageable on threaded portion 1121, when driving shaft 111 entrys into service, gear hobbing cam 112 utilizes threaded portion 1121 can drive driving-disc 122 rotation predetermined angulars, the workpiece that so is installed on the outside rotary disk just can be done angle rotation, and workpiece can generally rotate the processing operation whereby.
Above-mentioned the 4th rotary disk device 10 has the processing function of direction of rotation really, but on using, it still have very big problem to need to solve, above-mentioned active cell 11 is provided with gear hobbing cam 112 and is engaged and linked with driven unit 12, the characteristics of these gear hobbing cam 112 maximums are threaded portion 1121 root edges that contact with roller 1221, be that external diameter according to driving-disc 122 is arranged with as arc, allow the roller 1221 in the engagement can more deeply eat in the threaded portion 1121 whereby, can promote rotation precision in order to the peripheral speed difference problem of eliminating existing involute gear, and by deepening joggled strength to increase the service life, yet, general rotary disk device 10 normally is center emphasis part with the cam, above-mentioned gear hobbing cam 112 is because shape is quite special, for with roller 1221 appearance profiles match poor in order to eliminate peripheral speed, gear hobbing cam 112 each threaded portion 1121 profile all need to make special top rake, this kind gear hobbing cam 112 can only be manufactured on special machine, therefore the cost cost of whole gear hobbing cam 112 is quite expensive, cause the price of rotary disk device 10 effectively to reduce, in addition, when rotary disk device 10 will cut at the carrying workpiece, because the engagement that gear hobbing cam 112 and roller are 1221 is spent in sliding suitable, the effect that can't effectively provide brake to stop to driven unit 12, when workpiece will carry out the heavy cut operation, often bear the not lifting cutting moment of torque and can produce and depart from displacement, cause workpiece size precision variation, therefore rotary disk device 10 can only utilize the brake power of external motors itself only to carry out the evil spirit, and must adopt large-scale motor just to be enough to deal with the moment of torsion strength of heavy cut, yet this will strengthen overall volume, equipment cost also can improve relatively, also have and a bit be exactly, this driving-disc 122 is to be horizontal mode and gear hobbing cam 112 is meshing with each other, can be in order to possess for the volume of driving-disc 122 installings, rotary disk device 10 exterior case certainly will be extended towards the transverse direction development, and limited space utilization is quite disadvantageous for toolroom machine for this.
This shows that above-mentioned existing the 4th rotary disk device obviously still has inconvenience and defective, and demand urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of the 4th rotary disk device of new structure, just becoming the current industry utmost point needs improved target.
Because the defective that above-mentioned existing the 4th rotary disk device exists, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of the 4th rotary disk device of new structure, can improve general existing the 4th rotary disk device, make it have more practicality.Through constantly research, design, and, create the present invention who has practical value finally through after studying sample and improvement repeatedly.
