DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] The present invention provides a technical solution: a motor housing drilling tool, in this embodiment, such as Figure 1 and Figure 4 As shown, the base 1 is fixedly connected with a mounting frame 2, the mounting frame 2 is slidably connected with a slide seat 6, the slide seat 6 is provided with an adjustment component to drive, the slide seat 6 is fixedly connected with a vertically downward hydraulic cylinder 7, the output end of the hydraulic cylinder 7 is fixedly connected with a motor box 8, the lower side of the motor box 8 is fixedly connected with a gear box 10, the top of the gear box 10 is movably connected with a plurality of threaded rods 9, the lower end of the threaded rod 9 is rotatably connected with a gear column 15, the gear column 15 is simultaneously meshed with a gear disk 21, the lower end of the gear column 15 is provided with a drill bit 11, the length of the gear column 15 is much longer than the length of the gear disk 21, the drill bit 11 can be stored in the gear box 10, and driven by the motor in the motor box 8 The gear plate 21 rotates, causing the gear plate 21 to drive the gear column 15 meshing therewith to rotate accordingly, so that the drill bit 11 on the gear column 15 can be driven to drill holes at the same time. When the number of drill bits 11 needs to be adjusted, the threaded rod 9 can be rotated to move the thread at the top of the gear box 10. Because the lower end of the threaded rod 9 is rotatably connected to the top of the gear column 15, when the threaded rod 9 rotates, it will rotate relative to the top of the gear column 15. Therefore, when the threaded rod 9 moves, it drives the gear column 15 to move in the vertical direction until the drill bit 11 enters the gear box 10 as the threaded rod 9 rotates, thereby adjusting the number of drill bits 11. Similarly, the functions of multiple drill bits 11 at different depths when drilling can also be adjusted.

[0017] like Figure 1 and Figure 3As shown, the mounting frame 2 is slidably connected with a rotating shaft 4, and the angle of the motor housing fixed on the fixing seat 13 can be adjusted by rotating the rotating shaft 4. A limiting component is provided at the sliding connection between the rotating shaft 4 and the mounting frame 2. The end of the rotating shaft 4 away from the mounting frame 2 is fixedly connected with a fixing seat 13, and a symmetrical slot 22 is provided on the fixing seat 13. A through slot 12 is provided on the fixing seat 13 above the slot 22. Through the provision of the through slot 12, when drilling, the drill bit 11 can pass through the through slot 12 to drill holes in the support. The lower end of the fixing seat 13 is threadedly connected with a locking bolt 20. When the motor housing needs to be fixed, the two supports on the motor housing can be placed in the corresponding slots 22, and the locking bolt 20 can be screwed to fix the two supports, thereby achieving the function of fixing the motor housing.

[0018] like Figure 1 As shown, the adjustment component includes a transverse screw rod 5 rotatably connected to the top of the mounting frame 2, a slide rod (not shown in the figure) is fixedly connected to the mounting frame 2 on one side of the screw rod 5, and an adjusting motor 3 is fixedly connected to the outer side of the mounting frame 2. The output end of the adjusting motor 3 passes through the mounting frame 2 and is coaxially fixed to the screw rod 5. The slide seat 6 is sleeved on the screw rod 5, and the slide seat 6 is also slidably connected to the slide rod. The screw rod 5 is driven to rotate by the adjusting motor 3. Under the limit of the slide rod, the slide seat 6 can rotate along the thread direction of the screw rod 5, thereby achieving the function of adjusting the lateral position of the slide seat 6.

[0019] like Figure 4 As shown, a vertically downward motor is arranged in the motor box 8, and the output end of the motor extends into the gear box 10. The output end of the motor is coaxially fixed with the gear plate 21. The gear plate 21 is driven by the motor in the motor box 8, thereby achieving the function of driving the drill bit 11.

[0020] like Figure 1 and Figure 2 As shown, the limiting assembly includes two vertically distributed limiting grooves 18 opened on the outer side of the sliding connection between the rotating shaft 4 and the mounting frame 2, and a fixing ring 17 is fixedly connected to the outer side of the rotating shaft 4 at the limiting groove 18, and a clamping block 19 corresponding to the limiting groove 18 is fixedly connected to the outer side of the fixing ring 17. When the rotating shaft 4 needs to be rotated, the fixing ring 17 is first pulled out of the mounting frame 2, so that the clamping block 19 is disengaged from the limiting groove 18 and then rotated a multiple of 90°, and then the clamping block 19 on the fixing ring 17 is inserted into the limiting groove 18, thereby achieving the function of limiting the rotating shaft 4.

[0021] like Figure 1As shown, an electric lifting seat 14 is provided on the upper surface of the base 1, and the electric lifting seat 14 is located directly below the fixed seat 13. Through the setting of the electric lifting seat 14, when drilling, the electric lifting seat 14 can be started to contact the bottom of the motor housing, thereby supporting the motor housing and making the motor housing more stable when drilling.

[0022] like Figure 1 and Figure 2 As shown, one end of the rotating shaft 4 away from the fixing seat 13 is coaxially fixedly connected with a crank 16 , and the rotating shaft 4 can be conveniently rotated by rotating the crank 16 .

[0023] The present invention provides a motor casing drilling tool, and the specific working principle is as follows: when working, first place the two supports on the motor casing in the slot 22, fix them by the locking bolt 20, drive the rotating shaft 4 to rotate by the crank 16, so as to adjust the direction of the fixed motor casing, fix the position of the rotating shaft 4 after rotation by the limit assembly, and when the direction of the motor casing is fixed, start the electric lifting seat 14 to support the lower side of the motor casing, and at the same time drive the slide 6 to move by the adjustment assembly, so that after the slide 6 is located in the appropriate position, start the hydraulic cylinder 7, and gradually move the motor box 8 downward, so that the drill bit 11 drills the motor casing, and drives the gear column 15 to move by the threaded rod 9 to realize the function of adjusting the number of drill bits 11.
