[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figs. 1 to 3 This utility model provides an embodiment of an auxiliary device for arc-shaped opening of a semi-circular metal part, including a worktable 1 and a fixed base 2. The fixed base 2 is fixedly disposed on the rear side of the upper end of the worktable 1. A groove 201 is formed on the front side of the fixed base 2 near the upper end. A support base 5 extending through to the outside of the fixed base 2 is movably connected inside the groove 201. Below the support base 5 and slidably connected to the front surface of the fixed base 2, a slide block 7 is slidably connected. A first motor 8 is fixedly connected to the end of the slide block 7 away from the fixed base 2. The output end of a motor 8 is connected to a drill rod 9. A cylinder 6 is fixedly connected to the upper end of a support base 5. The output end of the cylinder 6 extends through to the bottom end of the support base 5 and is fixedly connected to the upper end of the first motor 8. A through groove 101 is provided below the drill rod 9 and at the upper end of the worktable 1. A half gear block 10 is rotatably connected inside the through groove 101 via a rotating shaft. Sliding grooves 1001 are provided on both the front and rear sides of the upper end of the half gear block 10. The upper ends of the front and rear sliding grooves 1001 are slidably connected to a clamping plate 12.

[0021] On the front and rear sides of the upper end of the half gear block 10, and at the ends of the two slide grooves 1001 that are far apart from each other, a fixing plate 11 is fixedly connected. At the ends of the two clamping plates 12 that are far apart from each other, a second threaded rod 13 is rotatably connected through a rotating shaft. One end of the second threaded rod 13 is threaded through the fixing plate 11 and extends to the outside of the fixing plate 11.

[0022] By placing the flat surface of the semi-circular metal part on the upper surface of the half gear block 10 and positioning it between the two clamping plates 12, and then rotating the second threaded rods 13 on both sides so that the threads of the second threaded rods 13 pass through the fixing plate 11, and rotating the rear end of the clamping plate 12, the clamping plate 12 is pushed to slide along the slide groove 1001 and approach the semi-circular metal part, thereby clamping and fixing the semi-circular metal part, and also adjusting the position of the hole to be opened on the semi-circular metal part.

[0023] A connecting plate 15 is fixedly connected to one side of the bottom end of the workbench 1 and below the fixed base 2. A gear 17 is connected to the front side of the connecting plate 15 near the bottom end via a second motor 16. The bottom end of the half gear block 10 extends through to the outer side of the bottom end of the workbench 1, and the outer surface of the half gear block 10 meshes with the outer surface of the gear 17. By starting the second motor 16, the gear 17 is driven to rotate. Then, through the meshing of the gear 17 and the half gear block 10, the half gear block 10 holding the semi-circular metal part is driven to rotate, so that the position of the hole to be opened on the arc surface of the semi-circular metal part can be adjusted.

[0024] The front surface of the half gear block 10 is provided with an arc-shaped groove 1002. The bottom end of the worktable 1 away from the connecting plate 15 is fixedly connected to a limiting block 14 that is slidably connected inside the arc-shaped groove 1002 by a connecting rod. By sliding the limiting block 14 inside the arc-shaped groove 1002, the half gear block 10 can rotate smoothly while avoiding overload of the half gear block 10.

[0025] A slide rod 3 is fixedly connected inside the groove 201. A first threaded rod 4 is rotatably connected to the top of the slide rod 3 via a throttle. The upper end of the support seat 5 is threadedly connected to the first threaded rod 4, and the bottom end of the support seat 5 is slidably connected to the slide rod 3. By rotating the throttle, the first threaded rod 4 is driven to rotate. While the first threaded rod 4 is rotating, the thread drives the support seat 5 to move. Under the limitation of the slide rod 3, the support seat 5 is moved to the top of the arc surface of the semi-circular metal part where a hole needs to be drilled.

[0026] When using the arc-shaped hole-opening auxiliary device for the semi-circular metal part, the flat surface of the semi-circular metal part is placed on the flat surface of the upper end of the half gear block 10 and positioned between the two clamping plates 12. Then, the second threaded rods 13 on both sides are rotated so that the threads of the second threaded rods 13 pass through the fixing plate 11 and are rotated to the rear end of the clamping plate 12, thereby pushing the clamping plate 12 to slide along the slide groove 1001 and approach the semi-circular metal part. In this way, the semi-circular metal part is clamped and fixed, and the position of the hole to be opened on the semi-circular metal part can be adjusted.

[0027] After the semi-circular metal part is clamped and fixed, the second motor 16 is started to drive the gear 17 to rotate. Then, through the meshing of the gear 17 and the semi-gear block 10, the semi-gear block 10 holding the semi-circular metal part is driven to rotate. This allows for adjustment according to the position of the hole to be opened on the arc surface of the semi-circular metal part. Furthermore, the limiting block 14 is slidably connected to the inside of the arc groove 1002, which allows the semi-gear block 10 to rotate smoothly while also preventing the semi-gear block 10 from being overloaded.

[0028] After the angle of the semi-circular metal part is changed, in order to avoid mismatch in the drilling position of the drill rod 9, the first threaded rod 4 is rotated by turning the throttle. At the same time as the first threaded rod 4 rotates, the thread drives the support seat 5 to move. Under the limit of the slide rod 3, the support seat 5 is moved to the top of the arc surface of the semi-circular metal part where a hole needs to be drilled. Then, the cylinder 6 is started to drive the first motor 8 and the drill rod 9 to move down. Then, the first motor 8 is started to drive the drill rod 9 to rotate, thereby opening a hole in the arc surface of the semi-circular metal part.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
