Description

Technical Field

[0001] The utility model relates to the field of honing processing equipment, in particular to a driving device for driving a main shaft of a honing machine to operate. Background Art

[0002] The current CNC honing machines, especially the long-stroke honing machines, all install the main shaft's rotating drive mechanism (including motor, reducer and reducer seat, etc.) directly on the rotating drive box. This not only increases the size of the drive box and its weight, but also the weight of the entire rotating drive motor must move with the drive box. When the spindle is reciprocating, this drive connection method is not only heavy, but also causes a serious increase in the inertia of the movement, which affects the low commutation efficiency of the main power mechanism of the honing machine, the large commutation impact, and the easy formation of random lines and folding lines on the surface of the workpiece, which not only affects the honing quality of the workpiece, but also further affects the service life of the machine tool lead screw and guide rail. In addition, under the same honing specifications, (reciprocating motor, reciprocating lead screw, reciprocating guide rail) need to be increased in model and specification, resulting in increased cost. Utility Model Content

[0003] The utility model aims to overcome the deficiencies in the prior art and to provide a honing machine driving device which reduces the weight to be driven when the rotating shaft reciprocates by changing the structure of the driving device.

[0004] The utility model is realized through the following technical scheme: a honing machine driving device, comprising a frame, a rotating transmission box is arranged on the frame, and a honing machine spindle is arranged at the output end of the rotating transmission box, characterized in that: the rotating transmission box is slidably connected to the frame, and the end of the frame is provided with a first driving module for driving the transmission module to move on the frame, and a second driving module for providing power to the rotating transmission box.

[0005] Furthermore, the second driving module includes a motor 1, an output end of the motor 1 is provided with a reducer, and an output end of the reducer is provided with a rotating drive shaft passing through a rotating transmission box.

[0006] Furthermore, the rotary drive shaft is arranged along the displacement direction of the rotary transmission box, one end of the rotary drive shaft is connected to the reducer, and the other end is provided with a bearing seat connected to the frame.

[0007] Furthermore, the first driving module includes a second motor and a transmission screw, one end of the transmission screw is connected to the second motor, and the other end is provided with a second bearing seat connected to the frame, and the transmission screw is provided with a mounting seat for driving the rotation transmission box to move.

[0008] Furthermore, a threaded sleeve used in conjunction with a transmission screw is provided on the mounting seat, guide blocks are provided on both sides of the mounting seat, and a linear guide rail used in conjunction with a guide switch is provided on the frame.

[0009] Furthermore, the linear guide rail is located at the upper end of the frame, and a damping module is provided at the connection between the linear guide rail and the guide switch.

[0010] Furthermore, the damping module comprises rubber strips arranged on both sides of the linear guide rail, the side walls of the rubber strips are provided with guide grooves, and the side walls of the guide blocks are provided with guide ridges used in conjunction with the guide grooves.

[0011] The beneficial effect of the utility model is that the honing machine driving device comprises a frame, a rotating transmission box is installed on the frame, a honing machine main shaft is installed at the output end of the rotating transmission box, the rotating transmission box is slidably connected to the frame, and a first driving module for driving the transmission module to move on the frame is provided at the end of the frame, and a second driving module for providing power to the rotating transmission box. By cooperating with the first driving module and the second driving module, the rotating transmission box can be driven to reciprocate on the frame while providing power to the rotating transmission box.
