Integrated water-cooled permanent magnet servo two-way clamping electric spindle structure

Abstract

The invention relates to an integrated water-cooled permanent magnet servo two-way clamping electric spindle structure. The integrated water-cooled permanent magnet servo two-way clamping electric spindle structure comprises a clamping base shell and a right bearing block. The right bearing block is embedded into one side in the clamping base shell, a spindle is coaxially mounted in the right bearing base, a spindle bearing is arranged between the right bearing base and the spindle, a rotor sleeve connected with the spindle is arranged on the outer side of the right bearing base, a stator is arranged on the portion, located on the outer side of the rotor sleeve, in the clamping base shell, an oil cylinder piston is axially mounted at one end of the spindle, a left rubber chuck and a rightrubber chuck are mounted in the oil cylinder piston and the spindle, and the left side of the oil cylinder piston is sleeved with an oil cylinder sealing cover. A hydraulic clamping oil inlet and a hydraulic loosening oil inlet are formed in the right bearing block, and a left bearing block sealing cover and a right bearing block sealing cover are mounted on the left side and the right side of theright bearing block. The brand-new structure is adopted, and the problems in the prior art are effectively solved.

Description

technical field [0001] The invention relates to the field of clamping spindles, in particular to an integrated water-cooled permanent magnet servo bidirectional clamping electric spindle structure. Background technique [0002] The two-way clamping spindles currently on the market are all produced in Taiwan or Japan. All of them are external belts, which are then driven by motors. Its biggest disadvantage is that it is bulky and takes up space (because it needs an external belt and motor). If the two-way clamping spindle is installed on the machine tool, it is hoped that the two-way clamping spindle can be servo-moved and fed. The current market two-way clamping spindle is designed for machine tools, and its transmission and sealing protection are very complicated. [0003] Because it is necessary to install the screw rod for servo movement, the servo motor for transmitting torque to the screw rod, and reserve space for installation, post-commissioning and maintenance, etc...

Problems solved by technology

Its biggest disadvantage is that it is bulky and takes up space (because it needs an external belt and motor)

If the two-way clamping spindle is installed on the machine tool, it is hoped that the two-way clamping spindle can be servo-moved and fed. The current market two-way clamping spindle is designed for machine tools, and its transmission and sealing protection are very complicated.

[0003] Because it is necessary to install the screw for servo movement and the servo motor for transmitting torque to the screw, and to reserve space for installation, post-commissioning and maintenance, etc., it takes up more space.

There is also a problem of sealing protection, because the two-way clamping spindle adopts an external belt and is driven by a motor. If it is placed horizontally and only moves left and right, then the motor is usually mounted on the top or mounted under the guide rail of the machine bed. If the motor is mounted on the top It is easy to protect the load motor, but it takes up more space

[0004] If the motor is mounted under the guide rail of the bed, the sealing is more troublesome, because the guide rail needs to open a rectangular long slot according to the moving distance. The longer the slot, the greater the impact on the rigidity of the guide rail, especially the line rail, because in the bed It is necessary to sacrifice a lot of ribs between the guide rails to open a rectangular slot between the guide rails
