Abstract
A high-revolution speed spindle assembly for numerically controlled machine tools comprises a spindle, a front cover, a rear cover, bearings, a sleeve and a sealing ring, the front bearing and the rear bearing are arranged on the spindle, an intermediate spacer bush is arranged between the front and the rear bearings, the front and the rear bearings are mounted in the sleeve, the front cover and a sealing gland which are arranged on the spindle are firmly connected with the sleeve through front bolts, the front bearing is positioned by the front cover and a labyrinth ring between the front cover and the sealing gland, the rear cover arranged on the spindle is connected with the sleeve through rear bolts, and the rear bearing is positioned by the sealing ring and locknuts on the spindle. The structure of the high-revolution speed spindle assembly is simple, the production cost is low, the high-revolution speed spindle assembly can be used for replacing imported like high-revolution speed spindle assemblies, and has a remarkable effect in increasing the surface roughness of machined workpieces, the revolution speed of the high-revolution speed spindle assembly can reach 6000 revolutions per minute, the statically detected end play of the spindle does not exceed 0.002mm, and the assembly precision is increased by about three times compared with the assembly precision of ordinary equipment.
Description
Technical field
The utility model relates to a kind of numerical control machine height of bed rotating speed main shaft assembly.
Background technology
The science and technology high speed development, people get more and more to high-precision, equipment requirement efficiently, and machining object requires characteristics such as attractive in appearance, that precision is high, speed is fast, so import sophisticated equipment demand is also more and more.The high-speed main spindle of import numerically controlled lathe is the price height not only, and buying hour is long, tends to influence manufacturing schedule.
The utility model content
The purpose of this utility model just provides a kind of simple in structure, precision is high, production cost is low numerical control machine height of bed rotating speed main shaft assembly.
Numerical control machine height of bed rotating speed main shaft assembly of the present utility model, comprise main shaft, protecgulum, bonnet, bearing, sleeve, sealing ring, be nested with fore bearing and rear bearing on the main shaft, before, middle spacer sleeve is set between the rear bearing, before, rear bearing is installed in the sleeve, the protecgulum and the seal cover that are nested with on main shaft are affixed by preceding bolt and sleeve, fore bearing is located by the labyrinth ring between protecgulum and protecgulum and seal cover, the bonnet that is nested with on main shaft links to each other with sleeve by the back bolt, rear bearing is by sealing ring on the main shaft and locking nut location, fore bearing inner spacing collar and fore bearing outer separator are set between the fore bearing, rear bearing inner spacing collar and rear bearing outer separator are set between the rear bearing.
Numerical control machine height of bed rotating speed main shaft assembly of the present utility model is simple in structure, production cost is low, can be used for the similar high rotating speed main shaft assembly of substituting import one, the surface roughness that improves workpiece there is especially significantly effect, it changes 6000 rev/mins of scooters, main shaft Static Detection end is jumped and to be no more than 0.002mm, has improved about three times than the assembly precision of conventional equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
