When the spline groove 36 is connected to the spline shaft, the spline shaft and the punching drill bit 35 are fixed by bolts. When a center hole or an irregular hole is punched on the electronic scale, the punching drill bit 35 is fixedly installed on the second spline shaft 221; a punching drive component is provided on the punching machine chassis 15, and the punching drive component is connected to the first spline shaft 22 and the second spline shaft 221. When the punching drive component drives the second spline shaft 221 to rotate, the punching drive component drives the four groups of first spline shafts 22 to rotate synchronously. When the component drives the second spline shaft 221 to rotate in the opposite direction, the punching drive component drives the first spline shaft 22 to rotate and drives the four sets of sliding seats 21 to slide back and forth along the slide groove 20. The punching drive component includes a main drive part for driving the first spline shaft 22 and the second spline shaft 221 to rotate and a slave drive part for driving the sliding seat 21 to slide; wherein the main drive part includes a fourth motor 27 fixedly connected to the punching machine chassis 15, and the output end of the fourth motor 27 is fixedly connected to the driving shaft 28, and the driving shaft 28 is fixedly connected to the second spline shaft 221; a mounting plate 24 is fixedly connected to the sliding seat 21, and a first transmission bevel gear 25 is rotatably connected to the mounting plate 24, and a second transmission bevel gear 25 is fixedly connected to the top of the first spline shaft 22 Wheel 26, and the first transmission bevel gear 25 is meshed with the second transmission bevel gear 26; a third spline shaft 23 is rotatably connected in the punching machine case 15, the third spline shaft 23 is transmission-connected to the driving shaft 28 through the second bevel gear set 29, the first transmission bevel gear 25 is slidingly connected to the third spline shaft 23, and the slave driving part includes a reducer 31 fixedly connected in the punching machine case 15, a transmission rod 33 is fixedly connected to the output shaft of the reducer 31, a reciprocating thread 34 is provided on the transmission rod 33, and the mounting plate 24 is meshed with the reciprocating thread 34; it also includes: a ratchet mechanism 30, the inner ring of the ratchet mechanism 30 is fixedly connected to the driving shaft 28, and the outer ring of the ratchet mechanism 30 is transmission-connected to the input shaft of the reducer 31 through the third bevel gear set 32.

[0036] Start the fourth motor 27. The fourth motor 27 drives the driving shaft 28 to rotate. The driving shaft 28 drives the second spline shaft 221 to rotate. At the same time, the driving shaft 28 drives the third spline shaft 23 to rotate through the second bevel gear set 29. The third spline shaft 23 drives the first driving bevel gear 25 to rotate. The first driving bevel gear 25 drives the second driving bevel gear 26 to rotate. The second driving bevel gear 26 drives the first spline shaft 22 to rotate.

[0037] In this embodiment, under the action of the ratchet mechanism 30, when the driving shaft 28 rotates forward (it can rotate clockwise or counterclockwise), it can drive the first spline shaft 22 and the second spline shaft 221 to rotate synchronously. When the driving shaft 28 rotates reversely (either clockwise or counterclockwise), the driving shaft 28 drives the third bevel gear set 32 to rotate under the action of the ratchet mechanism 30. The third bevel gear set 32 drives the transmission rod 33 to rotate. The transmission rod 33 drives the mounting plate 24 to move through the reciprocating thread 34, thereby driving the first spline shaft 22 to move along the diagonal of the electronic scale housing.

[0038] The punching drive assembly drives the rotation of five spline shafts, namely four first spline shafts 22 and one second spline shaft 221 simultaneously. When four diagonal holes are punched on the top of the electronic scale housing, punching drills 35 can be installed on the four first spline shafts 22. Then, the punching drive assembly drives the four first spline shafts 22 to rotate synchronously, thereby driving the four punching drills 35 to rotate synchronously. Then, the electronic scale housing is moved directly below the punching machine case 15. Then, the position adjustment mechanism drives the punching machine case 15 to descend, and further drives the punching drills 35 to descend to punch the electronic scale housing.

[0039] In summary, the device can flexibly meet different punching requirements. By changing the installation position of the punching drill 35 and adjusting the position of the punching machine case 15, the processing of various hole types can be easily achieved;

[0040] Automated control reduces manual intervention and improves production efficiency. At the same time, the multi-axis linkage design enables multiple punching drills 35 to work simultaneously, further shortening the production cycle and improving the punching efficiency of the diagonal holes of the electronic scale;

[0041] The design of the chute 20 and the sliding seat 21 enables the punching machine case 15 to be flexibly adjusted according to the different sizes and shapes of the electronic scale housing, ensuring the accuracy and adaptability of punching.

[0043] Start the second motor 10, the second motor 10 drives the second screw rod 11 to rotate, the second screw rod 11 drives the second mounting seat 9 to slide along the second guide rail 8, and the horizontal position of the drilling drill 35 is changed. Start the third motor 16, the third motor 16 drives the third screw rod 17 to rotate, and the third screw rod 17 drives the drilling machine box 15 to move up and down through the threaded barrel 19, so as to change the height and longitudinal position of the drilling drill 35.

[0045] Start the first motor 3, the first motor 3 drives the first screw rod 6 to rotate, and the first screw rod 6 drives the first mounting seat 4 to slide along the first guide rail 2, wherein the fixing box 5 is fixed to the first mounting seat 4 by bolts, and when punching holes in the casings of electronic scales of different models, different fixing boxes 5 can be replaced for fixing, wherein the first mounting seat 4 is provided with two stations for installing the fixing boxes 5, when one of the fixing boxes 5 is located directly below the punching box 15, the other fixing box 5 is located on the outside of the outer box, so that the staff or the manipulator can remove the punched casing of the electronic scale and fix the casing of the electronic scale that needs to be punched on the fixing box 5.

[0046] Among them, the top of the side of the fixed box 5 is provided with an inclined surface that slopes towards the center of the fixed box 5. This inclined surface is used to guide the card connection of the electronic scale housing to the fixed box 5, and the part with the inclined surface is supported by rubber or silica gel. When the unperforated electronic scale housing is card-connected to the fixed box 5, it will squeeze the inclined surface of the fixed box 5, making the connection between the electronic scale housing and the fixed box 5 sealed.

[0047] Refer to Figures 2 - 6 、 Figures 7 - 11 As shown in FIGS. 1 and 2, a piston plate 123 is slidably connected in the piston cylinder 12. The piston plate 123 is fixedly connected to the piston rod 13. The piston plate 123 divides the inside of the piston cylinder 12 into a first chamber 121 and a second chamber 122. Among them, the air inlet end of the first chamber 121 is fixedly connected to a second connecting pipe 42. A three-way joint 43 is fixedly connected to the second connecting pipe 42. One end of the three-way joint 43 is fixedly installed with the fixed box 5. The other end of the three-way joint 43 is fixedly installed with an overflow valve for admitting air into the second connecting pipe 42. The top of the first chamber 121 is provided with a one-way valve for discharging the gas in the first chamber 121. A first connection hole 38 is opened on the piston rod 13. The two ends of the first connection hole 38 are respectively communicated with the connection box 14 and the second chamber 122. A second connection hole 41 is opened in the sliding seat 21. A water inlet hole 39 is opened on the first spline shaft 22. The two ends of the water inlet hole 39 are respectively communicated with the spray hole 37 and the second connection hole 41. The connection box 14 is communicated with the second connection hole 41 through a first connecting pipe 40. One-way valves are provided at the inlet ends of both the connection box 14 and the second chamber 122.

[0048] When the perforating chassis 15 descends, the perforating chassis 15 drags the piston plate 123 to descend through the piston rod 13. During this process, the space in the first chamber 121 increases, and the space in the second chamber 122 decreases. During this process, the space in the first chamber 121 gradually increases, sucking the air in the sealed chamber formed between the electronic scale housing and the fixed box 5 through the second connecting pipe 42, reducing the gas pressure in the sealed chamber, making the gas pressure in the sealed chamber less than the outside. Under the action of the pressure difference, the connection between the fixed box 5 and the electronic scale housing becomes tighter. Furthermore, a gas pressure detection sensor 44 is installed in the fixed box 5. When the perforating chassis 15 descends to a specified height, it is detected by the gas pressure detection sensor 44 whether the pressure inside the sealed chamber reaches a preset threshold N. When the gas pressure is greater than the threshold N, it indicates that there is a crack at the top of the electronic scale housing, and then the control display host is controlled to alarm and prompt the staff. When the detected gas pressure reaches the threshold N, the control display host controls the perforating drill 35 to descend and contact the electronic scale housing for drilling.

[0049] Moreover, when the pressure inside the sealed chamber reaches the preset threshold M, the overflow valve on the three-way joint 43 sucks in external air to prevent excessive negative pressure from causing the punching machine case 15 and the punching drill 35 from being unable to descend.

[0050] Meanwhile, the space in the second chamber 122 decreases. Under the action of the one-way valve, the cutting fluid in the second chamber 122 is sent into the first connection hole 38. The cutting fluid passes through the connection box 14, the first connecting pipe 40, the second connection hole 41, the water inlet hole 39 in sequence, and finally sprays out through the spray hole 37 to cool the punching drill 35.

[0051] When the punching machine case 15 rises, the piston plate 123 moves upward, the space in the first chamber 121 decreases, and the space in the second chamber 122 increases. During this process, the air in the first chamber 121 is discharged. At the same time, as the space in the second chamber 122 increases, it sucks in the cutting fluid inside the cutting fluid tank. The cutting fluid tank is fixedly installed on the second mounting bracket 7 and is connected to the second chamber 122 through a pipeline.

[0052] In addition, the gas pressure detection sensor 44 can be replaced with a filter plate, and the discharge end of the first chamber 121 is connected to the cutting fluid tank through a pipeline. The first chamber 121 is used to circulate the cutting fluid, thereby reducing costs.

[0053] In addition, in this embodiment, the motor is controlled by the control display host to control the number of rotation turns of the motor, which cooperates with the lead screw to achieve the adaptive positioning of the workpiece.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
