After the movable plate 7 rotates 90 degrees following the rotating shaft 9, the bottom surface can contact the side wall of the support plate 13, and the tapping machine 5 or the drilling machine 11 is located directly above the center of the workbench 1. The side wall of the support plate 13 is provided with a locking assembly, and the locking assembly can fix the support plate 13 and the movable plate 7; the locking assembly is two pairs of electric push rods 12, and the two pairs of electric push rods 12 are respectively fixedly arranged on the left and right sides of the side wall of the support plate 13 and are located on both sides of the center of the side wall. A limiting hole 16 is provided on the end surface of the movable plate 7 and at a position corresponding to the telescopic end of the electric push rod 12, and the telescopic end of the electric push rod 12 can be inserted into the limiting hole 16; the limiting hole 16 is a hole with a large opening diameter and a small bottom diameter. The telescopic end of the electric push rod 12 is arranged in a hemispherical shape, and the diameter is smaller than the opening and larger than the bottom; the bottom of the movable plate 7 and corresponding to the position that can contact the side wall of the support plate 13 are respectively provided with a pressure sensor 17.

[0018] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0019] According to the instruction manual Figure 1-4It can be seen that before the utility model is put into operation, the movable plate 7 is in a horizontal state, and the drilling machine 11 and the tapping machine 5 are in a horizontal state, so that it is convenient for personnel to replace the drill bit and the tapping head. When in use, the personnel first fix the internal combustion engine parts to the center position of the upper surface of the workbench 1 through the clamp 2. To be precise, the drilling position of the part is located at the center position of the workbench 1. The clamp 2 can use the existing technology, which can realize the centering of the drilling position of the part and the fixing function of the part. To prepare for the drilling operation, the personnel start the motor 15 to work, and the output end of the motor 15 drives the shaft 9 and the movable plate 7 connected to the fixed plate 8 to rotate, so that Figure 1 and Figure 3 For example, the movable plate 7 and the drilling machine 11 and the tapping machine 5 on the mounting seat 6 are driven to rotate 90 degrees clockwise. After rotating 90 degrees, the right side of the bottom surface of the movable plate 7 just abuts against the right side wall of the support plate 13. At this time, the drilling machine 11 is facing the center position of the workbench 1, that is, the position where the part is to be drilled. Start the locking component, which can fix the movable plate 7 and the support plate 13, that is, to ensure the stability of the drilling machine 11 at this time. Start the electric slide rails 3 on both sides of the frame plate 14, so that the slide plate 4 drives the support plate 13, the movable plate 7 and the drilling machine 11 to move downward to drill the parts. After the drilling is completed, the electric slide rail 3, the electric push rod 12 and the motor 15 are reset to return to the initial state, and then the tapping operation is performed. The motor 15 rotates in the opposite direction, that is, counterclockwise, so that the left side of the bottom surface of the movable plate 7 after rotation just abuts against the left side wall of the support plate 13. At this time, the tapping machine 5 is facing the position where the part has just been drilled. The electric push rod 12 is started, the movable plate 7 is fixed again, and the tapping operation is started by the electric slide rail 3. Compared with the prior art, the drilling machine 11 and the tapping machine 5 of the utility model are arranged on the same device, and are switched by a simple rotation. After switching, the working positions of the two can be kept unchanged, the processing accuracy can be ensured, and there is no need to disassemble and reinstall parts between drilling and tapping operations, thereby improving work efficiency.

[0020] Among them, the locking components are two pairs of electric push rods 12, which are respectively fixed on the left and right sides of the side wall of the support plate 13 and located on both sides of the center of the side wall. The end surface of the movable plate 7 and the position corresponding to the telescopic end of the electric push rod 12 are provided with a limiting hole 16. When working, after the movable plate 7 rotates 90 degrees and contacts the supporting side wall, the telescopic end of the electric push rod 12 can be inserted into the limiting hole 16 to fix the movable plate 7 and ensure the stability of the drilling machine 11 and the tapping machine 5 during work. Of course, the stability can also be further ensured by setting the limiting hole 16 as a hole with a large opening diameter and a small bottom diameter. The telescopic end of the electric push rod 12 is set to be hemispherical, and the diameter is smaller than the opening and larger than the bottom. On the one hand, it is convenient to insert the telescopic end. On the other hand, after the telescopic end is inserted, it can abut against the inner wall of the limiting hole 16, fully contact, and there is no gap, thereby ensuring the stability of the fixation.

[0021] Among them, pressure sensors 17 are respectively provided at the bottom of the movable plate 7 and at the positions corresponding to the positions that can contact the side walls of the support plate 13. When the movable plate 7 contacts the support plate 13, the pressure sensor 17 can transmit a signal, indicating that the position is accurate at this time, and can also continue to transmit the signal to the fixing component. At this time, the movable plate 7 is fixed to ensure the accuracy of drilling and tapping.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
