[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0021] The present application provides a drilling and tapping device for mechanical and electrical equipment manufacturing, which is mainly used to solve the problem that holes need to be drilled before tapping, and then tapping with a tap. During this process, tool switching is required, which easily leads to position deviation between the drill rod and the tap during work, and they are not on the same axis, resulting in low quality of processed internal threads. The following technical solutions are provided. Figure 1-Figure 5 Make a detailed description:

[0022] A drilling and tapping device for manufacturing mechanical and electrical equipment mainly includes a device body 1 and a drilling and tapping assembly 2 installed on the device body 1. The drilling and tapping assembly 2 includes an electric push rod 21 vertically installed on the device body 1. The output end of the electric push rod 21 is downward and is installed with a mounting frame 22. A bidirectional motor 23 is provided inside the mounting frame 22. A drill rod 231 and a tap 232 are installed at two output ends of the bidirectional motor 23, respectively. The electric push rod 21 is used to move the mounting frame 22 up and down to facilitate drilling and tapping. The bidirectional motor 23 realizes rapid switching between the drill rod 231 and the tap 232, which simplifies the tool replacement process. The drill rod 231 and the tap 232 are located on the same axis, which improves the processing accuracy and ensures the quality of the internal thread. The two opposite sides of the bidirectional motor 23 are fixed with The two rotating rods 24 are on the same horizontal line, and both rotating rods 24 are rotatably installed on the mounting frame 22. The mounting frame 22 is provided with a driving motor 25 whose output end is fixed to one of the rotating rods 24. The driving motor 25 drives the connected rotating rod 24 to rotate, so as to realize the rotation of the bidirectional motor 23, thereby switching between drilling and tapping. A positioning rod 26 is fixed at the end of the other rotating rod 24, and at least one fixing rod 27 is movably inserted on the positioning rod 26. The mounting frame 22 is constructed with two fixing holes 28 located on the same straight line, and one end of the fixing rod 27 is movably inserted into one of the fixing holes 28. By inserting one end of the fixing rod 27 into the fixing hole 28, the angle of the bidirectional motor 23 can be fixed, so as to avoid the shaking of the bidirectional motor 23 during operation, which affects the final quality of the product.

[0023] In this example, see Figure 3 and Figure 4 The two fixing holes 28 are distributed in a rotating array with the rotating rod 24 as the central axis. The driving motor 25 drives the connected rotating rod 24 to rotate back and forth, and the angle of each rotation is one hundred and eighty degrees. The driving motor 25 drives the rotating rod 24 to rotate back and forth instead of rotating in a circle. The advantage of this is that it can avoid the tangling of the wires connected to the bidirectional motor 23, thereby ensuring the orderly production of the equipment.

[0024] For further information, see Figure 4A slot 261 is provided on the positioning rod 26, and the fixing rod 27 movably passes through the slot 261. The internal structure of the positioning rod 26 is provided with a connecting groove 262 connected to the slot 261, and a top block 263 is movably provided inside the connecting groove 262. A spring 264 is connected between the side of the top block 263 facing away from the slot 261 and the inner wall of the connecting groove 262. Under the elastic force of the spring 264, the top block 263 contacts the outer wall of the fixing rod 27, which can improve the stability of one end of the fixing rod 27 inserted in the fixing hole 28, thereby ensuring the stability of the bidirectional motor 23 when working and ensuring the quality of the product. The design of the top block 263 and the spring 264 provides additional stability during the tool switching process, reduces the positioning error caused by mechanical vibration or impact, and ensures the smooth progress of the processing process.

[0025] Furthermore, the drill rod 231 and the tap 232 are worn during use and therefore need to be replaced frequently. To facilitate the replacement of the drill rod 231 and the tap 232, please refer to Figure 5 A mounting cylinder 29 is fixed on the output end of the bidirectional motor 23, and a mounting rod 291 is movably inserted inside the mounting cylinder 29, and a mounting hole 292 is formed on the mounting rod 291. A screw 293 is threadedly inserted on the outer wall of the mounting cylinder 29, and one end of the screw 293 is inserted into the inner part of the mounting hole 292. The drill rod 231 and the tap 232 are respectively fixed to the ends of the two mounting rods 291. By inserting the mounting rod 291 into the inner part of the mounting cylinder 29, and rotating the screw 293 so that one end of the screw 293 is inserted into the inner part of the mounting hole 292, the mounting rod 291 can be fixed inside the mounting cylinder 29; a guide groove 294 is formed on the inner wall of the mounting cylinder 29 and in the length direction of the mounting cylinder 29, and a guide block 295 sliding inside the guide groove 294 is fixed on the outer wall of the mounting rod 291. The setting of the guide groove 294 and the guide block 295 can quickly locate, so that the screw 293 is quickly aligned with the mounting hole 292, thereby improving the speed of installation.
