Description

Technical Field

[0001] The utility model belongs to the technical field of motor rotor processing, and particularly relates to a drilling device for motor rotor processing. Background Art

[0002] The motor rotor is the rotating component inside the motor. It is the part that undergoes mechanical movement when the motor is working. In the electric motor, the main function of the rotor is to generate electromagnetic torque by interacting with the magnetic field generated by the stator, inducing current or changing the position of the magnetic poles, thereby driving the rotor to rotate and converting electrical energy into mechanical energy output.

[0003] The existing drilling device for motor rotor processing uses a clamping mechanism to quickly clamp the motor rotor placed on the placement table, and then a driving mechanism drives the drill downward to drill holes in the motor rotor. However, in actual use, due to the large number of motors produced at one time, personnel need to repeatedly fix and remove the motor rotor, which brings a great workload to the personnel and results in poor drilling efficiency for the motor rotor. Utility Model Content

[0004] In view of this, the utility model aims to provide a drilling device for motor rotor processing to address the deficiencies in the prior art. The device can quickly and stably clamp multiple motor rotors automatically and synchronously while drilling holes in the multiple motor rotors quickly and continuously, thereby improving drilling efficiency and facilitating use by personnel.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a drilling device for motor rotor processing, including a workbench, the four corners of the lower surface of the workbench are provided with supporting feet, the upper surface of the workbench is provided with a drilling table, the upper surface of the drilling table is provided with a supporting frame, the upper surface of the support frame is provided with an XYZ-axis linear slide, a drive box is provided on the left side of the slide of the XYZ-axis linear slide, a drill bit is provided at the lower end of the output shaft of the drive box, and the drilling table is also provided with a clamping and fixing module for clamping and fixing the motor rotor; two sliding doors with front and rear staggered arrangements are slidingly provided on the front side of the workbench, and handles are provided on the front sides of the sliding doors.

[0006] As a further improvement of the present invention, the clamping and fixing module includes a plurality of placement seats evenly arranged on the upper surface of the drilling table, a plurality of evenly distributed guide grooves are opened on the upper surface of the drilling table, and limit plates are slidably arranged inside the guide grooves. The drilling table is also provided with an electric drive unit for driving the limit plates to move; the electric drive unit includes a plurality of evenly distributed rotating shafts rotatably arranged inside the drilling table, an adjustment plate is fixedly sleeved on the upper end of the outer arc surface of the rotating shaft, and four evenly distributed linkage rods are rotatably arranged on the upper surface of the adjusting plate, and the ends of the linkage rods away from the adjusting plate are respectively rotatably connected to the vertically adjacent limit plates, and the drilling table is also provided with a driving component for driving the rotating shaft to rotate.

[0007] As a further improvement of the utility model, the driving assembly includes a gear fixedly sleeved on the lower end of the outer arc surface of the rotating shaft, four evenly distributed guide rails are arranged between the inner walls on the left and right sides of the drilling table, and sliding frames are slidably arranged between the two guide rails on the same side, and rack plates are arranged on the front and rear sides of the two sliding frames, and the rack plates are respectively meshed with adjacent gears, and an adjusting screw is rotatably arranged between the inner walls on the left and right sides of the drilling table, and the adjusting screw is respectively threadedly connected to the adjacent sliding frames, and two driving motors symmetrically distributed front and back are arranged on the right side of the drilling table, and the output shaft of the driving motor is fixed to the adjacent adjusting screw by a coupling; a control panel is arranged on the front side of the support frame, and the XYZ-axis linear slide, drive box and drive motor are all electrically connected to the control panel.

[0008] As a further improvement of the utility model, the upper ends of the limiting plates are sleeved with rubber sleeves.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, the motor rotors to be drilled are placed on the placement seats in sequence, so that the limit plates around each placement seat are close to the vertical center of the placement seat, and the motor rotors placed on the placement seats are clamped quickly and stably synchronously.

[0011] Secondly, the output shafts of the two driving motors respectively drive the adjusting screws connected to them to rotate, which then drives the sliding frame threadedly connected to them to slide between the two guide rails, and drives all the rotating shafts to rotate through the meshing relationship between the rack plate and the gear. Each adjusting plate drives the limit plates around it to move closer together through the linkage rod. Through the cooperation of the rack plate and the gear with the sliding frame and the adjusting screw, multiple motor rotors can be quickly and stably automatically and synchronously clamped at one time.
