Background technology
Mill spring machine is that two emery wheels polish two end faces of stage clip simultaneously about using; To reach the abrasive machine of setting height; Application number is that " the computer numerical controlled mill spring of Double End machine " patent of 201010536924.5 has only been mentioned the mill cover to the fixture of grinding spring on the specification background technology, lacks fully open to essential feature.At present, the vertical or horizontal mill spring machine structure of supplying on the market all is to do 360 degree rotations with the mill that has been covered with cover, and mill only some is between two abrasive grinding wheels, the stage clip quantity of participating in grinding in the mill simultaneously is few, yields poorly.Simultaneously, in grinding process, stage clip is to get into the emery wheel inner radius from the emery wheel outer radius, gets back to the emery wheel outer radius from the emery wheel inner radius again; When stage clip rigidly connects when touching external diameter, because highly big before the grinding, stage clip is big at the outer radius compress variation; Spring force causes the emery wheel power of cutting of rubbing big greatly, so abrasion of grinding wheel is big, a few dish stage clips grind; Inclination has just appearred in the outside in the abrasive wheel end face, and abrasive wheel end face is uneven, has had a strong impact on the stage clip perpendicularity after the grinding.In order to guarantee that the stage clip perpendicularity after the grinding meets the requirements, with regard to handy specific purpose tool abrasive wheel end face is carried out equating, not only bothered but also aggravated the emery wheel loss.Mill spring machine workload is very big, and accumulation gets up to be used to proofread and correct plane of grinding wheel and the man-hour and the emery wheel cost of loss are high.Say that more this structure does not have to revise automatically the function of emery wheel flatness.In view of this, the inventor has designed the mill parallel moving mechanism of mill spring machine in order to overcome above-mentioned defective, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of mill parallel moving mechanism that grinds the spring machine, plane of grinding wheel need not be revised during grinding, improving productivity, and the consumptive material consumption reduces.
To achieve these goals; Technical scheme of the present invention has been used parallel double crank quadric chain principle; When parallel double-crank rotated in the same way, the circular arcs of doing all around with the hinged connecting rods of two cranks moved, when connecting rod moves towards constant; The motion track that connecting rod (comprising the parts that are fixed on the connecting rod) is gone up each point be exactly radius be the long circle of crank, centers of circle of these circles all must be controlled on the middle footpath circumference that a diameter dimension is the inside and outside footpath of an emery wheel diameter mean value.Mill cover displacement disc of the present invention just is the equal of the circular arc parts that are fixed on the connecting rod, and the combination of slide and slide block just is the equal of a crank.
The mill parallel moving mechanism of mill spring machine comprises: be fixed on two mill cover displacement discs on the sleeve flange; Be provided with the adjustment packing ring between sleeve flange and the mill cover displacement disc, sleeve flange is connected on the slide block end face slide block axle on end through two angular contact bearings; The thickness of adjustment packing ring is changed according to the stage clip free height; When being applicable to the highly bigger stage clip of grinding; Let plane, stage clip stage casing near the plane of grinding the cover displacement disc, reduce the moment of flexure that the power of cutting of rubbing causes, this moment of flexure can produce the torsional deformation between mill cover displacement disc and its oval hole shank.
Two slide blocks are installed in respectively in two slides, slide block axle and slide axle relative position depart from the numerical value that state has embodied crank length.
Fixed the slide gear in the eccentric rotating shaft that is provided with below the slide, slide block axle axial line and slide gear axis line have departed from certain distance.
One be fixed on the machine shaft gear shaft simultaneously and two slide gears engaged, and drive two slide gears and rotate in the same way; The rotation of slide gear has driven the rotation of slide again, and the rotating drive slide block axle of slide is done the off-centre rotation, and two sleeve flanges follow the circular arc of doing all around to move with regard to driving mill cover displacement disc; Thereby making the stage clip that inserts in the cover is that the long circumference of crank moves as radius between the upper and lower emery wheel medial and lateral of rotation at a high speed, and contact abrasive wheel end face everywhere guarantees that abrasive wheel end face weares and teares evenly everywhere.
Two slides wherein one be provided with adjustable plate; Screw is fixed on adjustable plate on the slide through the screw of both sides; Through hole in the middle of set screw is passed is connected with slide block, turns set screw and just can adjust the relative position between slide block axle and the slide, is the equal of adjustment crank length.Notice that two slide block symmetrical planes must be in the same plane during adjusting.
The slide rotary gear shaft is fixed on the open cabinet through two angular contact bearings up and down; Sleeve flange also is fixed on the slide block axle through two angular contact bearings up and down.Be convenient to adjust the depth of parallelism between mill cover displacement disc and the emery wheel, the no gap of bearing rotation.
The benefit that is provided with like this is: because the circular arc that mill cover displacement disc is ceaselessly done among a small circle in the operating position moves; The stage clip of accepting grinding is come and gone between the external diameter in emery wheel move, let the whole end face of emery wheel all participate in grinding, wearing and tearing are no groove evenly; Abrasive wheel end face is put down all the time; Save the trouble of frequent trimming wheel end face, improved emery wheel service life, improved production efficiency.

The specific embodiment
Through accompanying drawing and embodiment the present invention is done further to set forth in detail below.
Like the mill parallel moving mechanism of Fig. 1 to mill spring machine shown in Figure 3, on mill cover mobile ring 1 annular array many covers 11, the stage clip 10 of grinding just to be inserted in and overlap in 11.
Its workflow is following:
The operative employee starts several motors, and upper and lower emery wheel 101 rotates simultaneously, and goes up emery wheel 101 and rotating whereabouts, the upper surface feeding to stage clip 10.Gear shaft 42 drives with two slide gears 41 of its engagement and does rotation in the same way; Be fixed on the also rotation thereupon of slide 4 on the same fulcrum with slide gear 41; Slide 4 has driven slide block 3 again and rotated, and is as shown in Figure 3, because slide block axle 31 is not collinear with the axial line of slide gear 41; The rotation of two slide gears 41 just drives two slide block axles 31 and does eccentric rotation, is the equal of that double-crank is in rotation.We define, and slide block axle 31 is exactly so-called crank length with the axial line deviation distance of slide gear 41.Slide block 3 is rotating around the axial line of slide block gear 41; Slide block axle 31 departs from far away more with the axial line of slide gear 41; Then slide block axle 31 produces next garden diameter also greatly; The distance that departs from can be adjusted through turning adjustable plate 43 middle set screw 44, is the equal of the length of regulating rotary crank, to adapt to the grinding needs of different spring external diameters.Notice that two slide block symmetrical planes should be parallel during adjusting.
Two sleeve flanges 2 are connected on two slide block axles 31 through angular contact bearing 45; Though the rotation of slide block axle 31 can not drive sleeve flange 2 rotations; But drive sleeve flange 2 and and then do the translation of roundlet arc, the mill cover displacement disc 1 that is fixed on above the sleeve flange 2 is also done the translation of roundlet arc thereupon.The center of circle of all roundlets is all dropped on the middle footpath between the emery wheel 101 interior external diameters.In grinding process, the motion track of each stage clip 10 is exactly that radius is " crank " long circle.Regulate " crank " length, the mobile circumferential size of stage clip 10 also changes thereupon, referring to Fig. 3, Fig. 4.The numerical value that we make twice crank length add the compression spring outside dimension equals half numerical value (being that the wheel grinding face diameter is to width) of the inside and outside footpath of emery wheel difference in size; Its positive error of crank length is no more than the spring external diameter; Setting will be in grinding process like this, lets all stage clips 10 between the maximum outside diameter of abrasive wheel end face and minimum diameter, move all the time; And gapped between the internal diameter of design cover 11 and stage clip 10 external diameters, allow stage clip 10 in cover 11, to relatively rotate, thereby; Realize that stage clip 10 end face every bits all have an opportunity to contact the purpose of external diameters in the emery wheel 101, revise the not flat spot on emery wheel 101 end faces automatically, guaranteed the emery wheel 101 end faces unanimity of wearing and tearing everywhere; Remain flatness preferably; Save the operation of revising plane of grinding wheel, improved production efficiency and saved emery wheel consumption, and stage clip 10 perpendicularity of grinding have been good.Set when requiring when last emery wheel 101 reaches to the upper end of stage clip 10 feeding size, the upper and lower end face of all stage clips is polished on the mill, and reaches consistent height, and last emery wheel 101 can upwards be return.Mill is changed in the machine stall, so that get into the grinding circulation of next round.
