In order to fill up domestic in this blank on the one hand, overcome the deficiency that existing associated mechanisms is appeared suddenly out in actual use.The invention provides a kind of novel high precision workpiece box rotating mechanism, the digitlization that this mechanism can not only realize workpiece box angle shows, also has rotation power-saving, do not need extra instrument, the advantage such as, long service life high without backlass, running accuracy.
Technical scheme provided by the invention is:
A kind of workpiece box rotating mechanism, rotary bottom plate is the rotation of the rotating shaft on planker and on planker by T connector bolts assemblies, drive unit is arranged on planker, drive unit connects driving biserial sprocket wheel, biserial sprocket wheel is meshed with the two-way chain that is arranged on rotary bottom plate circular arc side, described two-way chain is made up of two chains, the two ends of two chains are fixed on rotary bottom plate by two chain stays respectively, the front end of the first chain is fixed in the first chain stays, the tail end of the first chain is fixed in the second chain stays by tensioning nut by chain rod, the front end of the second chain is fixed in the second chain stays, the tail end of the second chain is fixed in the first chain stays by tensioning nut by chain rod, on rotary bottom plate, be provided with the magnetic railings ruler read head relative set on magnetic railings ruler and planker.
Concrete, described drive unit comprises handwheel, and handwheel, by decelerator connection chain wheel shaft, arranges biserial sprocket wheel on sprocket shaft, and described decelerator is arranged on speed reducer base, and adjustment packing ring is set on sprocket shaft, and decelerator top is provided with gland.
Concrete, described magnetic railings ruler is arranged on rotary bottom plate circular arc side by magnetic railings ruler lead-in.
Concrete, described magnetic railings ruler read head is fixed on planker by read head seat.
Concrete, rotating shaft is fixedly connected with planker by lining.
The invention has the beneficial effects as follows: energy digitlization angles of display value, without backlass, running accuracy is high, long service life, what instrument that can be extra just can be convenient and strength-saving rotates to desired angle by workpiece box.

The specific embodiment
As shown in Figure 1, a kind of workpiece box rotating mechanism, rotary bottom plate is the rotation of the rotating shaft on planker and on planker by T connector bolts assemblies.Rotating shaft is fixedly connected with planker by lining.Drive unit is arranged on planker.Described drive unit comprises handwheel, and handwheel, by decelerator connection chain wheel shaft, arranges biserial sprocket wheel on sprocket shaft.Described decelerator is arranged on speed reducer base, and decelerator top is provided with gland.Adjustment packing ring is set on sprocket shaft.Biserial sprocket wheel is meshed with the two-way chain that is arranged on rotary bottom plate circular arc side.Described two-way chain is made up of two chains, the two ends of two chains are fixed on rotary bottom plate by two chain stays respectively, the front end of the first chain is fixed in the first chain stays, the tail end of the first chain is fixed in the second chain stays by tensioning nut by chain rod, the front end of the second chain is fixed in the second chain stays, and the tail end of the second chain is fixed in the first chain stays by tensioning nut by chain rod.Described magnetic railings ruler is arranged on rotary bottom plate circular arc side by magnetic railings ruler lead-in.Described magnetic railings ruler read head is fixed on planker by read head seat.Magnetic railings ruler and magnetic railings ruler read head relative set.
Workpiece box is fixed on rotary bottom plate, and rotary bottom plate is pressed on planker with T connector bolt.The lining being arranged on rotating shaft and the planker on rotary bottom plate is used for determining pivot position.Magnetic railings ruler is fixed on rotary bottom plate circular arc side by magnetic railings ruler lead-in.Magnetic railings ruler read head is fixed on planker by read head seat, keeps certain gap with magnetic railings ruler relative set and with magnetic railings ruler.The display that the angle value that magnetic railings ruler read head is read is carried by it shows.Two chains of two-way chain are arranged on the circular arc side of rotary bottom plate, and are parallel to each other, but tension opposite direction is eliminated the gap between chain and the gear teeth of biserial sprocket wheel with this, and the gear teeth front and back flank of tooth of biserial sprocket wheel is all close to chain.When biserial sprocket wheel is rotated in the forward and the first chain laminating, by the first chain-driving rotary bottom plate motion, when the reverse rotation of biserial sprocket wheel, with the laminating of the second chain, move by the second chain-driving rotary bottom plate.Be synchronized with the movement with regard to biserial sprocket wheel and the realization of two-way chain like this, eliminated because causing the coarse problem of the asynchronous generation anglec of rotation of motion in the gap between biserial sprocket wheel and two-way chain.Biserial sprocket wheel is connected with the decelerator with handwheel by sprocket shaft.On speed reducer base 17, there is kidney slot, can regulate easily the relative position of biserial sprocket wheel 11 and chain 4.When the anglec of rotation, first unclamp the T connector bolt that compresses rotary bottom plate, rotate handwheel, the angle value demonstrating according to magnetic railings ruler is adjusted after angle, then locks T connector bolt.
