Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0021] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0022] Embodiment

[0023] As Figures 1-4 shown, a quick drilling tooling for fitters includes a support structure and a part 1 arranged inside the support structure. The part 1 includes a screw rod 101 and a nut 102. The nut 102 is fixedly arranged at one end of the screw rod 101. A plurality of holes 103 are arranged on the circumference of the nut 102, and these holes 103 are drilled after being clamped by using the drilling tooling of the present utility model. The support structure includes a support member 2, a support block 6, and a positioning rod 5. One end of the support member 2 is provided with a support groove 21 extending into the inside of the support member 2, and the other end is provided with a connection hole 22. The connection hole 22 penetrates through the support member 2 and extends into the support groove 21. The inner diameter of the connection hole 22 is smaller than the inner diameter of the support groove 21. The support block 6 is detachably arranged inside the support member 2. The part 1 is detachably connected in the support groove 21, and the screw rod 101 extends into the connection hole 22, and the nut 102 is supported in the support groove 21. A positioning hole 23 is arranged around the support member 2, and the positioning hole 23 communicates with the support groove 21. When the nut 102 abuts against the inside of the support groove 21, the positioning hole 23 is arranged opposite to the circumferential side surface of the nut 102. The position corresponding to the positioning hole 23 is the drilling position. That is, a drill bit or other equipment can be inserted into the positioning hole 23 to drill the nut 102 and finally drill out the holes 103. An opening 24 is arranged on the outer side of the support member 2. The opening 24 is arranged at one end of the support groove 21, and the opening 24 penetrates through the support member 2 and is connected to the support groove 21. The opening 24 facilitates observing the positions of the support block 6 and the part 1.

[0024] As Figures 1-4 shown, a threaded section Ⅰ211 is arranged inside the support member 2 at the inner wall position of the support groove 21. A threaded section Ⅱ61 is arranged on the surface of the support block 6. The threaded section Ⅱ61 cooperates with the threaded section Ⅰ211. During drilling, the part 1 will receive a large impact force. Screwing in the support block 6 can press the part 1 tightly inside the support member 2, further preventing the part 1 from sliding, making the drilling process more stable, and at the same time making the drilling position more accurate.

[0025] As shown Figures 1-4 in the figure, a channel structure and a limit groove structure are provided on the support member 2. The channel structure includes channel I 31 and channel II 32. Channel I 31 and channel II 32 are arranged at the end position of the opening 24, and the extension lines of channel I 31 and channel II 32 are perpendicular to each other. The limit groove structure includes limit groove I 41 and limit groove II 42. The limit grooves are arranged along the length direction of the support groove 21, and limit groove I 41 is aligned with channel I 31, and limit groove II 42 is aligned with channel II 32. A positioning groove 104 is provided at the top end of the nut 102. When the nut 102 is supported in the support groove 21, the positioning groove 104 is aligned with channel I 31 or channel II 32. When the positioning groove 104 is aligned with channel I 31, the positioning rod 5 extends into the positioning groove 104 through channel I 31, and the other end extends into the limit groove I 41; when the positioning groove 104 is aligned with channel II 32, the positioning rod 5 extends into the positioning groove 104 through channel II 32, and the other end extends into the limit groove II 42. The positioning rod 5 can prevent the part 1 from rotating during the drilling process. When the positioning groove 104, channel I 31 and limit groove I 41 are aligned and connected for a long time, the positioning rod 5 will inevitably cause wear to channel I 31 and limit groove I 41. At this time, the angle of the part 1 can be changed to align the positioning groove 104, channel II 32 and limit groove II 42, which does not affect the drilling.

[0026] Working principle: When it is necessary to position and drill the part 1, the part 1 is placed into the support member 2, the screw rod 101 extends into the connection hole 22, so that the nut 102 abuts against the support groove 21, and the position of the positioning groove 104 is adjusted to align the positioning groove 104, channel I 31 and limit groove I 41. At this time, the position of the positioning hole 23 is the drilling position. The positioning rod 5 is passed through channel I 31 and the positioning groove 104, and the other end of the positioning rod 5 extends into the limit groove I 41. The positioning rod 5 restricts the rotation of the part 1. Then, the support block 6 is screwed into the support groove 21, and the bottom of the support block 6 abuts against the positioning rod 5, pressing the part 1 tightly in the support member 2. The drilling device extends into the positioning hole 23 to drill the nut 102. The positioning in the whole process is simple and accurate, which improves the working efficiency of the workers. After the drilling is completed, the support block 6, the positioning rod 5 and the part 1 are removed one by one.

[0027] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
