Along with the development of China's mechanical industry, more and more to the demand of the high accuracy processing of workpiece, Compound Machining on market.Various horizontal Machining centers, cnc boring and milling machine and composite processing machine tool are equipped with after rotary table, by clamped one time, can complete whole or most of manufacturing procedures of workpiece, increase substantially Workpiece Machining Accuracy and production efficiency.In the process of workpiece, rotary table need to turn round by processing request.At present, the process equipment on market generally adopts revolution drive motor by Series Gear, worm screw, worm gear, to drive the revolution of rotary table.The rotary torque space less, that take that shortcoming is to provide is larger, and structure is more complicated.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of rotating transmission mechanism of rotary table that is suitable for is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A rotary table power drive mechanism, comprises motor, planetary reducer and rotary table, and described motor output shaft connects the power shaft of planetary reduction gear, and the output shaft of planetary reduction gear is connected with power transmission shaft by shaft coupling; It is characterized in that, also comprise bevel gear gear;
Described bevel gear gear comprises the bevel gear of a pair of right angle engagement, and gear shaft is established at the vertical bevel gear of the plate-like center of above-mentioned paired bevel gear, and the vertical bevel gear of described plate-like top gear shaft is provided with the first gear;
Described rotary table comprises the inside and outside revolving sleeve that the central shaft that is fixed on revolving bed and screw are nested inside and outside interfixing, on central shaft, cover has pair of bearings, described central shaft end face is established gland and is pressed solidly bearing and be bolted on central shaft end face, described inside and outside revolving sleeve is the sheathed bearing distributing up and down respectively, and described outer revolving sleeve is provided with the second gear that screw is connected for one week;
Described the first gear and the intermeshing transmission of the second gear.
Described bearing is taper roll bearing.
The utility model adopts a planetary reduction gear box that motor speed is dropped to desired speed; By shaft coupling and power transmission shaft band dynamic bevel gear, rotate.Bevel gear drives the spur gear on same axle to rotate; Spur gear drives connection all-in-one-piece workbench to do gyration again.It is simple in structure, compact, overcomes that to have taken rotary torque space less, that take larger, the defect such as structure is more complicated, and the rotary torque providing is large, practical, can be effectively for rotary table provides rotary motive power.
