DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0027] See also Figure 1-6 The utility model provides a technical solution: a stator core drilling tool, comprising a base 1, a fixed seat 2 is arranged on one side of the upper end of the base 1, and the fixed seat 2 and the base 1 are rotatably matched, a limited position column 8 is arranged at the middle position of the fixed seat 2, an electric telescopic rod 3 is arranged on the other side of the upper end of the base 1, and a support seat 4 is arranged at the output end of the electric telescopic rod 3;

[0028] It also includes a transmission cavity 9, which is opened inside the base 1, and a rotating shaft 10 is rotatably arranged on one side of the transmission cavity 9, one end of the rotating shaft 10 is fixedly connected to the fixed seat 2, and a transmission worm wheel 11 is arranged on the outer wall of the rotating shaft 10, and a transmission worm 12 is arranged in front of the transmission worm wheel 11, and the transmission worm 12 is rotatably connected to the transmission cavity 9, and the transmission worm 12 and the transmission worm wheel 11 are driven by the worm;

[0029] It also includes a sliding cavity 14, which is opened on one side of the fixed seat 2. A moving block 16 is arranged inside the sliding cavity 14. A pull rod 17 is fixedly arranged inside the moving block 16. A storage groove 19 is opened on one side of the fixed seat 2. One end of the pull rod 17 extends to the outside of the fixed seat 2, and the other end of the pull rod 17 passes through and extends to the inside of the storage groove 19. The pull rod 17 slides with the storage groove 19 and the sliding cavity 14.

[0030] When in use, pull the pull plate 21, and drive the arc-shaped clamping block 18 into the storage groove 19 through the pull rod 17. After putting in the stator core, release the pull plate 21, and the reset spring 20 pushes the moving block 16 and the pull rod 17 to make the arc-shaped clamping block 18 fit the outer wall of the stator core and be fixed. Start the electric telescopic rod 3 and the first motor 5, move the drill bit 6 down and rotate, and drill the stator core. The infrared generator 7 forms an infrared coil to help quickly locate the drilling position. When adjusting the drilling angle, start the second motor 13, and drive the rotating shaft 10 and the fixed seat 2 to rotate synchronously through the worm transmission of the transmission worm 12 and the transmission worm wheel 11 to achieve angle adjustment. The self-locking property of the worm transmission ensures that the fixed seat 2 is stable and does not rotate arbitrarily, thereby ensuring the stability of drilling.

[0031] See also Figure 1A first motor 5 is provided on one side of the support seat 4, a drill bit 6 is provided on the output end of the first motor 5 through a coupling, and one end of the drill bit 6 extends to the outside of the support seat 4, and the first motor 5 can directly drive the drill bit 6 to rotate, thereby realizing the drilling operation, simplifying the transmission structure and improving the working efficiency;

[0032] See also Figure 5 and Figure 6 Six infrared generators 7 are installed on one side of the lower end of the support seat 4 and are evenly distributed in a ring shape. The multiple infrared generators 7 can form a ring-shaped infrared network to help operators quickly determine the drilling position, thereby improving the accuracy and efficiency of positioning;

[0033] See also Figure 2 and Figure 3 A second motor 13 is provided on one side of the transmission cavity 9, and the output end of the second motor 13 is connected to the transmission worm 12 through a coupling. The transmission worm 12 is driven to rotate by the second motor 13, so that the angle between the fixing seat 2 and the stator core can be adjusted to achieve multi-angle drilling, thereby increasing the flexibility of the equipment;

[0034] See also Figure 6 A guide rod 15 is bonded and fixed to the front end of the sliding cavity 14. The guide rods 15 all penetrate the moving block 16, and the guide rods 15 all slide with the moving block 16. The guide rods 15 provide a stable sliding track for the moving block 16, ensuring the accuracy and reliability of the clamping action;

[0035] See also Figure 2 and Figure 4 A return spring 20 is sleeved on the outside of the pull rod 17 at one end inside the sliding cavity 14. One end of the return spring 20 is connected to the sliding cavity 14, and the other end of the return spring 20 is connected to the moving block 16. The return spring 20 can automatically push the moving block 16 and the pull rod 17 back to their original positions after the pull plate 21 is released, thereby realizing the automatic operation of clamping and releasing.

[0036] See also Figure 1 , Figure 2 and Figure 4 An arc-shaped clamping block 18 is provided at one end of the pull rod 17 located inside the storage groove 19, and a pull plate 21 is provided at one end of the pull rod 17 located outside the fixed seat 2. By pulling the pull plate 21, the pull rod 17 and the arc-shaped clamping block 18 can be easily operated to clamp and release the stator core, and the operation is simple and quick.

[0037] Working principle: when in use, pull the pull plate 21 outward, the pull plate 21 will drive the pull rod 17 to move synchronously, the pull rod 17 will cause the moving block 16 to squeeze the reset spring 20, and at the same time the pull rod 17 will drive the arc-shaped clamping block 18 to move into the storage groove 19. At this time, the stator core is placed into the fixed seat 2 along the limiting column 8, and the pull plate 21 is released. Under the elastic recovery action of the reset spring 20, the moving block 16 will drive the pull rod 17 to move toward the direction of the stator core, and the pull rod 17 will drive the arc-shaped clamping block 18 to squeeze and fit the outer wall of the stator core, so that the stator core can be clamped and fixed, and the deviation of the stator core during drilling can be avoided. Starting the electric telescopic rod 3 can make the drill bit 6 move downward, and starting the first motor 5 can make the drill bit 6 rotate under the transmission of the coupling, so that the stator core can be drilled. Before drilling, the electric telescopic rod 3 can be started to move the drill bit 6 downward, and starting the first motor 5 can make the drill bit 6 rotate under the transmission of the coupling, so that the stator core can be drilled. A plurality of infrared generators 7 are activated. When the infrared generators 7 distributed in a ring shape emit infrared rays, a ring-shaped infrared coil can be formed. The position of the drill bit 6 drilling a hole is within the circle. The operator can quickly determine the position of the drilling hole by simply judging the position of the infrared coil at the upper end of the stator core. The positioning is fast. When the drilling position needs to be changed after the drilling is completed, the operator can start the second motor 13. The second motor 13 can rotate the transmission worm 12 through the coupling. Since the transmission worm 12 and the transmission worm wheel 11 are worm-driven, the transmission worm wheel 11 can be driven to make the rotating shaft 10 rotate synchronously. The rotating shaft 10 can drive the fixed seat 2 to rotate synchronously, thereby realizing the rotation of the fixed seat 2 and adjusting the drilling angle of the stator core. At the same time, since the worm drive has self-locking properties, the fixed seat 2 will not rotate arbitrarily, thereby ensuring the stability during drilling.
