Description
Technical field
The utility model relates to the hole process equipment, relates in particular to a kind of friction-type numerical control rotary circular dividing table.
Background technology
The conventional holes process equipment uses radial drilling machine more, adopts the method for artificial line to determine hole relevant position degree before the processing, because artificial line error is bigger, so hole relevant position precision is relatively poor.And have the numerical control rig of (comprising import) now, and key function mechanism is numerical control scale-division platform mechanism, its hydraulic table also comprises hydraulic system, floats workbench, clamping body, gear clearance elimination mechanism by hydraulic pressure, servo-drive system control on the structure; The typical course of work is: after hydraulic table floats, servo-drive system Electric Machine Control workbench calibration, anti-backlash mechanism control calibration gap error in the calibration process, hydraulic table fell after calibration was finished, the clamping body chucking is finished a basic actuation cycle after the process finishing.Equipment integral body is huge, complicated, fault rate height, cost height; Gear clearance elimination mechanism particularly, drive the pinion rotation by hydraulic motor, workbench is applied a reciprocal active force, perhaps by changing pinion structure, adjust the fit-up gap of gear, to play the crack effect that disappears, all there is unstability in these measures, care and maintenance is strict, the maintenance cost height.
Summary of the invention
The utility model provides a kind of novel friction-type numerical control rotary circular dividing table, solves the problem that existing radial drilling machine and numerical control rig exist.For realizing above purpose, the utility model by the following technical solutions: the floral disc ⑴ of friction-type numerical control rotary circular dividing table is fixedlyed connected with main shaft ⑸ and gear wheel ⑹; Idler wheel mechanism ⑶, friction mechanism ⑻, decelerator ⑼ are fixedlyed connected with supporting disk ⑷ respectively; The roller ⑵ supporting floral disc ⑴ of idler wheel mechanism ⑶; Friction mechanism ⑻ contacts with the outer diametric plane of floral disc ⑴; The pinion ⑺ that decelerator ⑼ top is fixedly connected and gear wheel ⑹ engagement;
Described floral disc ⑴ is fixedlyed connected with main shaft ⑸ and gear wheel ⑹ by bolt;

The beneficial effects of the utility model are: the indexing accuracy that has improved workbench greatly, by with the supporting use of radial drilling machine, greatly improve hole Working position precision, compare with standard numerical control rig, to bore effect identical with numerical control on indexing accuracy, under certain condition alternative numerical control rig; Structure is simplified greatly, substitute the numerical control rig hydraulic system, float scratch diskette, clamping body, anti-backlash mechanism; Energy consumption is low, maintenance cost is low; With the supporting cost of radial drilling machine only be 1/10th of import numerical control rig.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the overall structure schematic diagram of friction-type numerical control rotary circular dividing table;
Fig. 2 is the partial schematic diagram that comprises idler wheel mechanism.
Illustration: floral disc 1, roller 2, idler wheel mechanism 3, supporting disk 4, main shaft 5, gear wheel 6, pinion 7, friction mechanism 8, decelerator 9, encoder 10.
The specific embodiment
As shown in Figure 1, friction-type numerical control rotary circular dividing table is made of floral disc 1, roller 2, idler wheel mechanism 3, supporting disk 4, main shaft 5, gear wheel 6, pinion 7, friction mechanism 8, decelerator 9 and encoder 10.Floral disc 1 is connected and fixed by bolt and main shaft 5 and gear wheel 6, forms an integral body and carries out calibration and rotate; Idler wheel mechanism 3 is installed on the supporting disk 4 by bolting, and sees Fig. 2 by roller 2 supporting floral disc 1(); Friction mechanism 8 contacts with the circumferencial direction diametric plane of floral disc 1 by being bolted on the supporting disk 4, and friction plate can be regulated by screw, and the pretightning force that screw imposes on friction plate is elastic pressure, and the size by adjusting pretightning force is to reach best friction effect; Decelerator 9 is fixed on the supporting disk 4, links to each other pinion 7 and gear wheel 6 engagements with the pinion 7 on top by axle key; Encoder 10 links to each other with main shaft 5 by axle key.
When the workbench calibration, digital control system is sent instruction, and decelerator 9 drives pinion 7 rotations, and pinion 7 drives gear wheel 6 and rotates, and gear wheel 6 and then drive floral disc 1 rotate jointly with main shaft 5, carry out calibration; Whether the rotation calibration that encoder 10 detects main shaft 5 is accurate, and with the signal back digital control system, in order to carry out next step operation, guarantees accurately to control calibration; The friction plate of friction mechanism 8 rubs mutually with the circumferencial direction diametric plane of floral disc 1, and the rotator inertia by fricative damping containment floral disc 1 guarantees that indexing position is accurate, plays the double action of automatic anti-backlash and auto lock, does not need other auxiliary body additionally to control.
