Summary of the invention
The purpose of this utility model is to provide a kind of machining accuracy and production efficiency height, the high accuracy grinding carriage dividing mechanism of the combined numerically controlled grinding machine that equipment investment is few, so that under the condition of a clamping of workpiece, the conical surface, shoulder, cylindrical, screw thread, fillet and the non-circular surfaces of workpiece carried out the multiple operation composite grinding.
The grinding carriage dividing mechanism of composite numerically controlled grinder that the utility model provides comprises slide, rotary grinding carriage, plane of rotation bearing, bearing block, column, torque motor, rotor cover, angular encoder, locking device; Wherein, described column is fixed on the slide center, and described bearing block is positioned on the slide, and described plane of rotation bearing is positioned on the bearing block, and described rotary grinding carriage is installed on the plane of rotation bearing; Described torque motor is installed between bearing block and the rotary grinding carriage, and the stator of torque motor is connected with bearing block, and the rotor of torque motor is connected with the rotor cover; Described rotor cover is connected with rotary grinding carriage; Described locking device is installed on the rotary grinding carriage top, and the axostylus axostyle flange that matches with described locking device is arranged on described column; Described angular encoder places the top of column.
In the utility model, flexibly connect by bearing between rotary grinding carriage and the column; Be connected by the plane of rotation bearing between rotary grinding carriage and bearing block and the slide.
The utility model is from stability, the reliability of grinding carriage integral body, the high accuracy of assurance grinding carriage dividing mechanism positioning accuracy and the multi-angles such as feasibility of processing technology aspect are set out, design panoramic table location structure, detect and the compensation error of division, and employing high pulling torque motor-driven, can realize the calibration of grinding carriage on arbitrarily angled, have very high calibration positioning accuracy.
The utility model can make the workpiece on the numerically control grinder realize multi-functional grindings such as grinding cylindrical, end face, the conical surface, endoporus under the situation of a clamping.Improve the machining accuracy and the production efficiency of workpiece greatly, reduce equipment investment, satisfy the production of multistation high accuracy processing flexibility and processing.
Description of drawings
Fig. 1 is the structure cutaway view of high accuracy grinding carriage dividing mechanism.
Number in the figure: 1, slide, 2, column, 3, bearing block, 4, motor stator, 5, rotor, 6, plane of rotation bearing, 7, rotary grinding carriage, 8, bearing, 9, the rotor cover, 10, locking device, 11, the axostylus axostyle flange, 12, the encoder seat, 13, angular encoder.
The specific embodiment
As shown in Figure 1, the utility model high accuracy grinding carriage dividing mechanism is made up of slide 1, column 2, bearing block 3, motor stator 4, rotor 5, plane of rotation bearing 6, rotary grinding carriage 7, bearing 8, rotor cover 9, locking device 10, axostylus axostyle flange 11, encoder seat 12 and angular encoder 13 etc.
This grinding carriage dividing mechanism directly drives revolution by torque motor.By motor stator 4 and bearing block 3 relative fixed, drive the rotation that rotors cover 9 and rotary grinding carriage 7 are realized with respect to motor stator 4 by rotor 5.The revolution required drive is directly driven by torque motor, reduces the loss of energy.Consider the high position precision requirement of grinding carriage dividing mechanism, between the parts of relative motion, adopt the plane rotation bearing 6 that can two-wayly bear axial load and additional radial load and frivolous moment to support, in order to bear the load in the grinding process.At column 2 tops angular encoder 13 is installed, controls the angular error of grinding carriage dividing mechanism by the revolution of control moment motor.After the grinding carriage calibration puts in place, lock, guaranteed that the positional precision of grinding carriage can not change because of the influence that is subjected to cutting force, and avoid torque motor is produced extra moment of torsion or impact by locking device 10.
