[0002] Motor production and processing is an important sector in the entire machinery manufacturing industry. In addition to general mechanical-like structural parts, motors also have special conductive, magnetic and insulating parts. Therefore, in the process of motor production and processing, some special processing may be required for various metalworking and assembly used in general machinery production.

[0003] Especially in the production process of the shaft, when the shaft is used for part connection, it may be necessary to punch holes at an angle on the shaft. However, most of the existing equipment punches holes vertically and cannot adjust the punching angle, which makes it difficult to meet the needs of the production process. If the angle is adjusted by hand, it may affect the processing accuracy of the shaft. At the same time, some shafts may not be regular circles, and the existing clamps may not be clamped firmly. Therefore, we propose a punching auxiliary device for motor production and processing with adjustable punching angle to solve the above problems. Utility Model Content

[0024] Specifically, the designed annular base 1 can be supported above the part to be punched, and a first U-shaped seat 2 is installed on each side of the upper end surface of the annular base 1. Subsequently, the two first connecting frames 4 are rotatably connected to the corresponding first U-shaped seats 2, so that the first connecting frames 4 can swing back and forth in the first U-shaped seats 2 to change the inclination angle of the drill bit 11, and then the first connecting frame 4 can be positioned in the first U-shaped seat 2 by fastening. In addition, guide rods 5 are vertically installed on the two first connecting frames 4, and the slider 7 can slide up and down on the guide rod 5, and the drill bit 11 is connected between the two sliders 7 through the mounting frame 9. Therefore, the slider 7 drives the drill bit 11 to move downward while moving downward. In order to enable the drill bit 11 to perform its drilling operation while moving downward, a driving member 10 is selected to be installed on the mounting frame 9, and the driving member 10 drives the drill bit 11 to perform the drilling operation, wherein the driving member 10 can adopt an existing motor or pneumatic motor.

[0026] The specific structure of the "first connecting frame 4" mentioned above is as follows:

[0027] The first connecting frame 4 includes a first fixed block 41, a side plate 42 and a limit block 43 which are connected as a whole. The side plate 42 is located at the bottom of the first fixed block 41, and the limit block 43 is installed with the side of the side plate 42. The first fixed block 41, the side plate 42 and the limit block 43 are connected as a whole, and the connection can be fixed by welding, wherein the upper end face of the first fixed block 41 is fixedly connected to the lower end face of the guide rod 5, and the limit block 43 is located on the side of the side plate 42. Subsequently, the second threaded rod 13 passes through the threaded hole of the first U-shaped seat 2 and the limit block 43 is abutted against the inner wall of the groove of the first U-shaped seat 2, so that the first connecting frame 4 can be locked in the position after the first U-shaped seat 2 is rotated.

The middle part of the first rotating shaft 12 is inserted into the mounting hole 44 of the first U-shaped seat 2 and is assembled in a clearance fit manner. The two ends of the first rotating shaft 12 are inserted into the gap between the first U-shaped seats 2 to connect the bearings, so that the rotation of the first rotating shaft 12 can be realized.

[0029] The specific connection between the first fixed block 41 and the guide rod 5 is as follows: a second fixed block 51 is arranged on the top of the first fixed block 41, and the second fixed block 51 is connected to the guide rod 5 as a whole. The first fixed block 41 and the second fixed block 51 are provided with through holes 14 for fasteners to pass through, and the first fixed block 41 and the second fixed block 51 are connected as a whole by fasteners.

[0030] In order to prevent the slider 7 from detaching from the guide rod 5, a nut 8 is detachably connected to the top of the two guide rods 5. On the one hand, the nut 8 can wrap the upper end surface of the guide rod 5 to achieve the purpose of protection; on the other hand, the nut 8 can also prevent the slider 7 from sliding out from the top of the guide rod 5.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
