Bearing ring grinding equipment introduction
|
|
Bearing standard parts just by inner and outer ring, cage, rolling body composed of four parts, but only involves the bearing ring - end processing equipment has a wide range of processing equipment; Cylindrical processing equipment; Outer ring groove (rolling) processing equipment; Inner ring groove (rolling) processing equipment; Inner ring inner hole machining equipment; And outer rim processing equipment; Rolling body surface processing equipment and so on.
Now to a new generation of bearing ring CNC grinding processing equipment of structure characteristic and using the new technology features a simple introduction.
1. CNC grinding equipment, the main structure and technical features
1)Grinding equipment adopts seriation, standardization, generalization, modular design. To reasonably according to the needs of different users of different combinations to meet the personalized needs of users in a timely manner.
2)Grinding machine control system adopts the high-end digital CNC system configuration and low-end CNC system configuration in two forms. The user can according to the specific circumstances of your business order.
3)Feed system and grinding wheel finishing and finishing compensation system adopts ac servo motor directly by flexible coupling with ball screw drive for the precise movements of machine components.
4)Feed and compensation board box structure adopts high rigidity and high precision cross (or ball) linear guide rail and ball screw, modular design. Centralized lubrication device for the guide rail and ball screw, timing quantitative automatic oil lubrication.
5)Workpiece spindle structure of sleeve, ac frequency conversion motor frequency control of motor speed, in order to adapt to the requirement of different grinding workpiece than.
6)The inner surface of grinding machine grinding high power frequency electric spindle rigidity, feed of workpiece and grinding wheel reciprocating feed is realized by using two axis ac servo motor driver and reciprocation. Grinding wheel oscillation is implemented by ac servo motor, coarse grinding and fine grinding automatically adjustable amplitude and frequency. For tapered roller bearings and cylindrical roller bearing outer ring grinding equipment, when to correct the raceway grinding, grinding wheel two ac servo axis linkage operation, according to the logarithmic curve grinding the raceway has cut into the vibration grinding, in order to make sure the outer raceway grinding out the logarithmic curve shape of the crown.
7)Outer surface of the grinding wheel spindle use of dynamic and static pressure bearing or dynamic pressure of two kinds of structure forms, according to the requirement of the user for selection. Feed system and the system of compensation for grinding wheel dressing and dressing are driven by ac servo motor three axis. For tapered roller bearings and cylindrical roller bearing inner ring grinding equipment, when correcting the raceway grinding wheel fixed axis of biaxial linkage, the function of the numerical control system function builds a logarithmic curve shape forming grinding wheel, plunge-cut grinding to ensure that the raceway crown shape.
8)Manipulator is in the form of a variety of up and down in order to for the user to choose from:
<1>Single arm turning up and down<2>Arms swing up and down<3>Push-pull rotary up-down material. Above devices are driven by hydraulic implementation of each action
9) Sealing temperature electrical control cabinet, handheld unit operation easy to adjust the knife. There are two kinds of electrical control cabinet form: independent electrical control cabinet; Bed back type electrical control cabinet.
10) Independent hydraulic station on lathe bed behind easy to adjust and resolve the problems of oil leakage of hydraulic parts.
11) Machine adopts full shield shell, beautiful shape, the operation and pleasant.
2. Numerical control over lapping machine's main structure and technical characteristics
1)Control system adopts PLC + NC NC system, color touch screen display.
2)Simplex two-step superfinishing, automatic switching oil stone can realize the function of coarse fine superfinishing, large reciprocating small oscillation, oscillation equipment with static pressure cylindrical guide, suitable for crown superfinishing.
3)Large reciprocating driven by ac servo motor to crown the realization of the function of superfinishing.
4)The change of the workpiece spindle speed is realized by using frequency control of motor speed, in order to meet the needs of the different grinding ratio.
5)Sharpening stone the oscillation frequency of variable frequency adjustable, suitable for machining of different requirements.
6)Electromagnetic centerless fixture, inner ring diameter, outer diameter, transverse orientation, roller compaction, the automatic up-down material manipulator.
7)Sealing temperature electrical control cabinet, electric control cabinet has two kinds: the form of independent electrical control cabinet; Bed back type electrical control cabinet.
8)Independent hydraulic station on lathe bed behind easy to adjust and resolve the problems of oil leakage of hydraulic parts.
9)Machine adopts full shield shell, beautiful shape, the operation and pleasant. Two stage filtration system(magnetic separator + Non-woven filter paper)
