Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 As shown in the figure, a punching device for a motor sound insulation pad includes a main board 1. A rotation component is installed directly above the main board 1. The rotation component includes a mounting bracket 2. A rotating shaft 3 is rotatably installed through the two sides of the mounting bracket 2. Four different punching heads 4 are equidistantly installed on the outer wall of the rotating shaft 3. An annular groove 5 is opened inside one side of the mounting bracket 2. A side ear 6 is installed on the outer wall of one side of the rotating shaft 3. A sliding rod 7 is fixedly connected to one side of the side ear 6, and the sliding rod 7 is slidably installed inside the annular groove 5. A sliding block 8 is slidably installed inside the annular groove 5. Pressure sensors 9 are installed on both sides of the sliding block 8.

[0024] An L-shaped frame 15 is installed at the top side edge of the main board 1. A cylinder 16 is installed on the top side of the L-shaped frame 15. An installation cavity 17 is installed at the acting end of the cylinder 16. Two connecting rods 18 are symmetrically and slidably penetrated and installed inside the installation cavity 17.

A buffer spring 21 is fixedly connected between the support plate 20 and the installation cavity 17. An installation frame 2 is fixed to the bottom side of the support plate 20. A control panel 35 is installed at the top side edge of the main board 1. During operation, in practical applications, there will be various motor sound insulation pad processing tasks with different specifications and requirements. Whenever there is a need to process holes with different apertures or shapes, if the stamping head 4 cannot be quickly switched, it will cause production interruption, thereby reducing the production efficiency of the sound insulation pad. When it is necessary to select the stamping head 4 according to different processing requirements, first move the sliding block 8 along the annular groove 5 to the position of the selected stamping head 4. Start the servo motor 13 through the control panel 35. The servo motor 13 drives the worm 14 to rotate. The worm 14 meshes with the worm gear 11, thereby driving the rotating shaft 3 to rotate, and the stamping head 4 rotates accordingly. During the rotation process, the sliding rod 7 will slide inside the annular groove 5. When the sliding rod 7 contacts the sliding block 8, the pressure sensor 9 will detect the pressure signal and transmit the signal to the control panel 35. The control panel 35 controls the servo motor 13 to stop. At this time, the required stamping head 4 is exactly accurately positioned at the working position, thereby ensuring the accuracy of hole punching and improving the flexibility of processing. The model of the pressure sensor 9 is BMP180;

[0025] During the hole punching process, the cylinder 16 pushes the installation cavity 17 downward, driving the installation frame 2 and the stamping head 4 installed on the bottom side of the support plate 20 to perform stamping operations. When the stamping head 4 contacts the sound insulation pad, the generated impact force will be transmitted to the support plate 20. At this time, the connecting rod 18 will slide inside the installation cavity 17, and the buffer spring 21 will be stretched, thereby effectively absorbing the impact force in cooperation with the damper, reducing vibration and noise, and improving the smoothness of hole punching.

[0026] Please refer to Figure 1 、 2As shown in FIGS. 5, a negative pressure chamber 22 is installed on the top side of the main board 1. An installation ring 23 is installed on the top side of the negative pressure chamber 22. A plurality of limiting rods 24 are slidably installed at equal intervals inside the installation ring 23. One end of each limiting rod 24 is fixedly connected to a limiting block 25. A tension spring 26 is fixedly connected between the limiting block 25 and the installation ring 23. The tension spring 26 is sleeved on the outer wall of the limiting rod 24. The other end of the limiting block 25 is fixed with an arc-shaped clamping block 27 inside the installation ring 23. A material discharging hole 28 is opened at the central position of the negative pressure chamber 22. Eight through holes 29 are opened at equal intervals inside the negative pressure chamber 22 on the inner side of the installation ring 23. A filter plate 30 is installed inside the negative pressure chamber 22. An air outlet pipe 31 is connected to one side of the negative pressure chamber 22. A pump 32 is installed on the outer wall of the air outlet pipe 31. A movable door 33 is installed on one side of the negative pressure chamber 22 by means of a hinge. A fixed buckle 34 is fixedly installed on one side of the movable door 33. During operation, in practical applications, when drilling holes in the sound insulation pad, it is necessary to ensure the stable position of the sound insulation pad, and at the same time, the main board 1 needs to be kept clean. The motor sound insulation pad to be processed is placed inside the installation ring 23. The arc-shaped clamping block 27 clamps the edge of the sound insulation pad under the action of the tension spring 26, further improving the stability of the sound insulation pad during processing and making it in the central position, thereby improving the drilling accuracy. At the same time, the pump 32 is started to generate negative pressure inside the negative pressure chamber 22. The negative pressure acts on the sound insulation pad through the through holes 29, so that the sound insulation pad is firmly adsorbed inside the installation ring 23. The remaining materials generated during the drilling process will enter the inside of the negative pressure chamber 22 through the material discharging hole 28. The filter plate 30 can prevent the remaining materials from entering the air outlet pipe 31 and causing blockage of the pump 32. When it is necessary to clean the remaining materials, the movable door 33 can be conveniently opened to take out the remaining material impurities generated by drilling.

[0027] Working principle: The motor sound insulation pad to be processed is placed inside the installation ring 23. The arc-shaped clamping block 27 clamps the edge of the sound insulation pad under the action of the tension spring 26, further improving the stability of the sound insulation pad during processing and making it in the central position, thereby improving the drilling accuracy. At the same time, the pump 32 is started to generate negative pressure inside the negative pressure chamber 22. The negative pressure acts on the sound insulation pad through the through holes 29, so that the sound insulation pad is firmly adsorbed inside the installation ring 23;

[0028] When it is necessary to select the stamping head 4 according to different processing requirements, first move the sliding block 8 along the annular groove 5 to the position of the selected stamping head 4. Start the servo motor 13 through the control panel 35. The servo motor 13 drives the worm 14 to rotate. The worm 14 meshes with the worm gear 11, thereby driving the rotating shaft 3 to rotate. The stamping head 4 rotates accordingly. During the rotation process, the sliding rod 7 will slide inside the annular groove 5. When the sliding rod 7 contacts the sliding block 8, the pressure sensor 9 will detect the pressure signal and transmit the signal to the control panel 35. The control panel 35 controls the servo motor 13 to stop. At this time, the required stamping head 4 is exactly positioned accurately at the working position, thus ensuring the accuracy of punching and improving the flexibility of processing. The model of the pressure sensor 9 is BMP180;

[0029] During the punching process, the air cylinder 16 pushes the installation cavity 17 to move downward, driving the mounting rack 2 and the stamping head 4 installed on the bottom side of the support plate 20 to perform stamping operations. When the stamping head 4 contacts the sound insulation pad, the generated impact force will be transmitted to the support plate 20. At this time, the connecting rod 18 will slide inside the installation cavity 17, and the buffer spring 21 is stretched, so as to effectively absorb the impact force in cooperation with the damper, reduce vibration and noise, and improve the smoothness of punching;

[0030] The remaining materials generated during the punching process will enter the negative pressure cavity 22 through the blanking hole 28. The filter plate 30 can prevent the remaining materials from entering the air outlet pipe 31 and causing blockage to the pump 32. When it is necessary to clean the remaining materials, the movable door 33 can be conveniently opened to take out the remaining material impurities generated by punching.
