[0020] Embodiment

[0021] The present utility model provides a stamping device for the production of motor stator and rotor punching sheets. Refer to Figures 1 - 3 As shown, it includes a workbench 1. In the middle of the top end face of the workbench 1, there is a limit post for sleeving the stator and rotor punching sheet 2. On the top end face of the workbench 1 on both sides of the limit post, there are symmetrically arranged baffles 3. On the outer end face of the baffle 3, there is a support plate 10 welded. On the top end face of the support plate 10, there is a first lifting cylinder 11. Between the tops of the two baffles 3, there is a bearing plate 4. On the top end face of the bearing plate 4, there is a second lifting cylinder 5. The output end of the second lifting cylinder 5 extends to the bottom of the bearing plate 4 and is provided with a driving plate 6. On the bottom end face of the driving plate 6, there is a rotating motor 7. On the rotating shaft of the rotating motor 7, there is a mounting plate 15. On the bottom of the mounting plate 15, there is a drilling machine 9. A clamping mechanism 8 is arranged on the workbench 1. Through the arrangement of the clamping mechanism 8, the degrees of freedom of the stator and rotor punching sheet 2 sleeved on the limit post in the front, back, left, and right directions can be restricted, improving the stability during the punching of the stator and rotor punching sheet 2.

[0022] Furthermore, a pressure plate 14 is coaxially arranged above the limit post. Through the arrangement of the pressure plate 14, the degrees of freedom of the stator and rotor punching sheet 2 stacked on the limit post in the up and down directions can be restricted, further improving the stability during the punching of the stator and rotor punching sheet 2. At the same time, it avoids the stator and rotor punching sheet 2 being separated from the limit post when the drilling machine 9 moves upward, affecting the punching efficiency. On both sides of the pressure plate 14, there are symmetrically arranged connecting plates 12 integrally formed with it. One end of the connecting plate 12 extends to the outside of the baffle 3 and is fixedly connected to the output end of the first lifting cylinder 11.

[0023] Furthermore, a connection groove 13 for the up-and-down displacement of the connection plate 12 is formed through the baffle 3. Limiting grooves are symmetrically formed on the inner side walls of both sides of the connection groove 13, and limiting blocks 16 adapted to the limiting grooves are symmetrically arranged on both sides of the connection plate 12. Through the arrangement of the limiting blocks 16 and the limiting grooves, the stability of the first lifting cylinder 11 driving the pressing plate 14 to move up and down is improved.

[0024] Among them, a plurality of through holes 17 for the punching drill 9 to pass through and punch the stator and rotor punching sheets 2 are formed through the pressing plate 14. The number of the through holes 17 is the same as the number of holes to be punched on the stator and rotor punching sheets 2, and the diameter of the through holes 17 is larger than the diameter of the holes to be punched on the stator and rotor punching sheets 2.

[0025] Reference Figure 3 As shown, the clamping mechanism 8 includes a clamping cylinder 801 arranged on the bottom end face of the workbench 1. Fixed plates 802 are symmetrically arranged on the output ends on both sides of the clamping cylinder 801. The top of the fixed plate 802 extends to the outside of the top of the workbench 1 and is provided with a clamping plate 803 with an arc-shaped inner side wall. A reinforcing plate 804 with a triangular cross-section is arranged at the connection between the clamping plate 803 and the fixed plate 802. Through the arrangement of the reinforcing plate 804, the connection strength between the clamping plate 803 and the fixed plate 802 is improved, and at the same time, the stability of the clamping plate 803 clamping the stator and rotor punching sheets 2 is improved.

[0026] Further, guiding blocks 805 with a trapezoidal structure are symmetrically arranged on both sides of the fixed plate 802. A fixing groove 18 for the left-and-right displacement of the fixed plate 802 is formed through the workbench 1. A guiding groove adapted to the guiding blocks 805 is formed on the inner side wall of the fixing groove 18. Through the arrangement of the guiding groove and the guiding blocks 805, the stability of the clamping cylinder 801 driving the fixed plate 802 to move left and right is improved, and at the same time, the stability of the clamping plate 803 clamping the stator and rotor punching sheets 2 is improved.

[0027] The working principle of the utility model is as follows:

[0028] During use, first, a plurality of stator and rotor punching sheets 2 are sleeved and stacked on the limit posts for positioning. Then, the clamping cylinder 801 is started to drive the fixed plate 802 to drive the clamping plate 803 to clamp and fix both sides of the stator and rotor punching sheets 2. Next, the first lifting cylinder 11 is started to drive the pressing plate 14 to move downward to press and fix the top of the stator and rotor punching sheets 2. The second lifting cylinder 5 is started to drive the drilling rig 9 to move downward to punch a plurality of stator and rotor punching sheets 2. After the holes are drilled, the second lifting cylinder 5 drives the drilling rig 9 to move upward to separate from the stator and rotor punching sheets 2. The rotating motor 7 is used to drive the mounting plate 15 to drive the drilling rig 9 to rotate, so as to process the next hole. The utility model effectively improves the processing efficiency, avoids the shaking of the stator and rotor punching sheets 2 during the drilling process, and improves the processing quality of the stator and rotor punching sheets 2.
