[0002] The motor uses the principle that a current-carrying conductor rotates due to the force it receives in a magnetic field. It is an electromagnetic device that can convert electrical energy into mechanical energy. The fixed part of the motor is called the stator, and the part that rotates in the stator is the rotor. The motor's rotor consists of an iron core and a rotating shaft inserted in the iron core. The production of a motor rotor requires multiple processes, including drilling holes at the end of the rotating shaft. The drilling process is generally completed with the help of drilling equipment.

[0003] A motor shaft bidirectional drilling device described in the announcement number CN219274529U includes a mounting frame, a dual-axis motor is installed above the mounting frame, the output shaft of the dual-axis motor is connected to a transmission shaft, the end of the transmission shaft is connected to a driving gear, one side of the driving gear is connected to a driven gear, a transmission rod is fixed inside the driven gear, a mounting piece is fixed on one side of the transmission rod, a drill bit is arranged at the end of the mounting piece, and two adjustment cylinders are symmetrically arranged on the upper surface of the mounting frame, and the output ends of the two adjustment cylinders are connected to fixed bearings. The utility model can synchronously drive the two driving gears to mesh with the driven gears to rotate through the dual-axis motor, so that the transmission rod can rotate, thereby synchronously driving the two drill bits to rotate, so that the two ends of the motor shaft can be synchronously drilled, the processing efficiency is improved, and the practicability is strong.

[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Embodiment 1:

[0040] like Figures 1 to 5 As shown, this embodiment proposes a motor shaft drilling device, including an operating table 1, a movable plate 2, a rotating ring 3, an adjusting ring block 4, a positioning component 5 for positioning the adjusting ring block 4, and a control component 6 arranged on the upper side of the movable plate 2 to drive one of the rotating rings 3.

[0041] Among them, an operating table 1 serving as a working platform for drilling the motor shaft has foot supports installed at the four corners of its lower side, and a vertical slide groove 7 is opened in the middle position of the upper side, and vertical columns 9 are installed on the front and rear sides of the upper end of the operating table 1, and the columns 9 are used to install a drill bit 10 for drilling the shaft, and the drill bit 10 is fixed at the upper end of the column 9 close to each other. A movable moving plate 2 is installed on the upper side of the operating table 1, and a slider 11 that can be inserted into the inside of the slide groove 7 is installed at the lower end of the moving plate 2, and the slider 11 is threadedly connected with the screw rod 8 arranged inside the slide groove 7. The screw rod 8 is controlled and driven by the servo motor 18 installed on the front side of the outside of the operating table 1, so that the slider 11 moves back and forth with the moving plate 2 inside the slide groove 7 as the screw rod 8 rotates.

[0042] Baffles 12 are installed on the front and back of the upper side of the movable plate 2, and a circular mounting hole 13 is provided at the upper end of the front side of each baffle 12, a rotatable ring 14 is provided inside the two mounting holes 13, and a swivel 3 is installed on the front side outside the ring 14, and a rotatable adjustment ring block 4 is provided on the front side of the two swivel rings 3, and three evenly distributed linkage slots 16 are provided on the outer wall of the adjustment ring block 4, and a linkage frame 17 is provided inside the linkage slot 16, and the front and rear of the outer side of the linkage frame 17 and the front and rear walls inside the linkage slot 16 are rotatably connected together.

[0043] Three evenly distributed clamping rods 15 are arranged at the front and rear of the outside of the swivel 3. One end of the rear side of the clamping rod 15 is rotatably connected to the swivel 3, and the other end is inserted into the inside of the adjusting ring block 4 through the inside of the linkage slot 16, and the linkage frame 17 is sleeved on the outside of the clamping rod 15. The clamping rod 15 can be synchronously adjusted by rotating the adjusting ring block 4, and the end of the clamping rod 15 inside the adjusting ring block 4 can be adjusted to move closer to or farther from each other. The free end of the clamping rod 15 inside the adjusting ring block 4 is used to realize the function of clamping rotating shafts of different diameters.

[0044] After the rotating shaft is clamped, it is necessary to ensure that the adjusting ring block 4 will not rotate relative to the rotating ring 3, so it is necessary to use the positioning component 5 to keep the two relatively fixed. A mounting block 501 is installed on the upper rear side of the outer upper end of the adjusting ring block 4, and there is a rotatable secondary connecting block 503 in front and behind the mounting block 501, and at the same time, there is a rotatable main connecting block 502 on the upper side of the front end of the outer ring 3. The main connecting block 502 and the secondary connecting block 503 on the same baffle 12 are connected by a screw 504. The screw 504 is rotatably connected to the main connecting block 502 and is threadedly connected to the secondary connecting block 503. The rotation of the screw 504 can realize the function of adjusting the rotation of the adjusting ring block 4 and achieving relative fixation between the rotating adjusting ring block 4 and the rotating ring 3. Then the control component 6 is used to drive one of the rotating rings 3 to rotate, so that the clamped rotating shaft rotates.

[0045] Embodiment 2:

[0046] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0047] A gear ring 601 with teeth facing outward is installed on the outer rear side of a front ring 14, and a driving gear 602 meshing with the gear ring 601 is rotatably connected to the lower rear side of a front baffle 12. Driven by a driving motor 603 installed on the front side of the upper end of the movable plate 2, the driving gear 602 rotates with the gear ring 601, and the swivel 3 rotates on the baffle 12. Due to the clamping of the motor shaft by the clamping rod 15, the two swivels 3 can rotate synchronously.

[0048] The servo motor 18 is used to control the rotation of the screw rod 8, and the movable plate 2 is controlled to move forward and backward. The motor shaft that is clamped and in a rotating state moves forward and backward. Under the work of the two front and rear drill bits 10 drilling holes alternately, holes are drilled at both ends. When the movable plate 2 moves forward, the drill bit 10 on the rear side can dissipate heat. When it moves backward, the drill bit 10 on the front side can dissipate heat. After the drilling is completed, the screw 504 is rotated, and the free ends of the clamping rod 15 are moved away from each other to loosen the shaft, and a new shaft that needs to be drilled is replaced, and then the screw 504 is reversed, the shaft is clamped, and it moves forward and backward to drill.

[0049] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.
