Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides a positioning device for license plate processing, including a positioning processing platform 1. Four support legs 11 are fixedly installed in a rectangular array at the bottom of the positioning processing platform 1. A license plate positioning mechanism 2 is provided at the top of the positioning processing platform 1. A drilling mechanism 3 is provided above the license plate positioning mechanism 2. The license plate positioning mechanism 2 includes a license plate placement plate 21. A positioning drive frame 22 is fixedly installed on the rear top side of the license plate placement plate 21. The positioning drive frame 22 has a front-to-back through positioning moving groove. A servo motor 23 is fixedly installed on the right side of the positioning drive frame 22. The output shaft of the servo motor 23 passes through the inner cavity of the positioning moving groove and is fixedly installed with a positive and negative threaded rod 24. The outer wall of the positive and negative threaded rod 24 is left... On the right sides, there are two threaded walls with opposite threads. The outer walls of the two threaded walls are threaded with adjusting moving plates 25. The two adjusting moving plates 25 are slidably connected to the positioning moving groove. The front side of the two adjusting moving plates 25 is fixedly installed with drilling positioning plates 26. The drilling positioning plates 26 are located above the license plate placement plate 21. The two drilling positioning plates 26 are opened with two vertically penetrating positioning holes 27. The license plate placement plate 21 is opened with two vertically penetrating chip removal holes 28. The rear side of the top of the positioning processing platform 1 is fixedly installed with an electric push rod 29. The output end of the electric push rod 29 is fixedly connected to the rear side of the license plate placement plate 21. The output length of the electric push rod 29 is the same as the length of the drilling positioning plate 26.

[0024] The servo motor 23, powered by the start-up wire, drives the rotation of the positive and negative threaded rod 24 inside the positioning drive frame 22. The threaded wall of the positive and negative threaded rod 24, with its opposite threads on the left and right sides, is connected to the threaded adjustment plate 25. This allows the two adjustment plates 25 to drive the two drilling positioning plates 26 to move relative to each other. The encoder can precisely control the servo motor 23 to achieve precise positioning of the positioning hole 27. After the two rear holes are drilled, the drill rod 35 can be driven to rise and slightly disengage from the positioning hole 27. Then, the electric push rod 29 is quickly started and fully retracted to the output end, which moves the license plate placement plate 21 backward, so that the drill rod 35 is aligned with the front positioning hole 27. Similarly, it is pressed down to pass through the drill hole, thereby achieving rapid positioning drilling for different holes on different license plates.

[0025] like Figure 3 , Figure 4 , Figure 5As shown, the bottom left and right sides of the license plate placement plate 21 are both attached to the top of the positioning processing platform 1. The drilling mechanism 3 includes a portal plate 31. The two vertical parts of the portal plate 31 are respectively fixedly installed on the top left and right sides of the positioning processing platform 1. A hydraulic cylinder 32 is fixedly installed at the top of the horizontal part of the portal plate 31. The hydraulic cylinder 32 can be controlled by a proportional valve. The proportional valve can accurately control the flow and pressure of hydraulic oil according to the magnitude of the input signal, thereby achieving precise control of the hydraulic cylinder stroke. The proportional valve combines the advantages of on-off hydraulic valve and servo valve, and has the characteristics of fast response speed and high control accuracy. The output end of the hydraulic cylinder 32 extends to the bottom of the horizontal part of the portal plate 31 and is fixedly installed with a pressure plate 33. Drilling motors 34 are provided on the bottom left and right sides of the pressure plate 33. Drill rods 35 are fixedly installed on the output shafts of the two drilling motors 34. The pressure plate 33 is fixedly installed on the top left and right sides of the pressure plate 33, and the two limit slide rods 36 are slidably connected to the horizontal position of the door plate 31. The bottom of the pressure plate 33 is provided with a slide groove 331. The slide rod 332 is fixedly installed between the left and right sides of the inner wall of the slide groove 331. Two motor sliders 333 are slidably installed on the outer wall of the slide rod 332. The bottom of the two motor sliders 333 is fixedly connected to the top of the two drilling motors 34. The bottom of the positioning processing platform 1 is fixedly installed with a collection box 13. The top of the positioning processing platform 1 is provided with a through hole 12 that penetrates into the inner cavity of the collection box 13. The through hole 12 is located below the license plate placement plate 21. The inner cavity of the collection box 13 is slidably installed with a debris collection drawer 14. The rear end of the debris collection drawer 14 penetrates to the rear side of the collection box 13.

[0026] The hydraulic cylinder 32 is activated to drive the pressure plate 33 to descend slightly under the control of the proportional valve until the drill rods 35 of the output shafts of the two drilling motors 34 are engaged in the rear positioning holes 27 of the drilling positioning plate 26, thus achieving positioning. When the pressure plate 33 descends, it can be kept stable by sliding the limit slide rod 36 against the horizontal position of the gate plate 31. Since the drill rods 35 are located inside the positioning holes 27, the two drilling motors 34 can be directly driven to adjust synchronously by sliding the motor slider 333 against the outer wall of the slide rod 332 in the slide groove 331. After adjustment, the hydraulic cylinder 32 and the two drilling motors 34 can be activated to drive the pressure plate 33 and the two drill rods 35 to pass through the positioning holes 27 to drill the license plate. The debris generated during drilling will fall directly into the debris collection drawer 14 in the collection box 13 through the debris fallout through hole 28 and through hole 12 for collection. When cleaning is required, the debris collection drawer 14 can be pulled out directly.

[0027] like Figure 6As shown, a clamping groove 211 is provided at the bottom of the license plate placement plate 21. The clamping groove 211 is located between two chip removal holes 28. A motor 212 is fixedly installed on the left side of the license plate placement plate 21. The output shaft of the clamping groove 211 passes through the inner cavity of the clamping groove 211 and is fixedly installed with a positive and negative threaded rod 213. The outer walls of the positive and negative threaded rod 213 are respectively provided with threaded walls 2 with opposite threads on the left and right sides. The outer walls of the two threaded walls 213 are threaded with movable upright plates 214. The top left and right sides of the license plate placement plate 21 are respectively provided with movable grooves 216 that pass through the inner cavity of the clamping groove 211. The tops of the two movable upright plates 214 pass through the two movable grooves 216 to the top of the license plate placement plate 21 and are fixedly installed with clamping plates 215.

[0028] When processing the license plate, the license plate can be aligned with the lower part of the two drilled positioning plates 26 and inserted until it abuts against the front side of the positioning drive frame 22, thus placing it on top of the license plate placement plate 21. Then, by starting the motor 212 powered by the long wire, the positive and negative threaded rod 213 in the clamping slide 211 can be driven to rotate. The threaded wall 213 with opposite threads on the left and right sides of the outer wall of the positive and negative threaded rod 213 is connected to the threaded connection of the two moving upright plates 214, which can control the two clamping plates 215 to move closer to each other on the top of the license plate placement plate 21 until the license plate is clamped and fixed. This allows for quick fixing of longer new energy vehicle license plates and shorter fuel vehicle license plates.

[0029] The working principle of the positioning device used for processing this license plate will be explained in detail below.

[0030] like Figure 1-6As shown, when processing license plates, the license plate can be aligned with the lower part of the two drilled positioning plates 26 and inserted until it abuts against the front side of the positioning drive frame 22, thus placing it on top of the license plate placement plate 21. Then, by starting the motor 212 powered by the long wire, the positive and negative threaded rods 213 in the clamping groove 211 can be driven to rotate. The threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rods 213 are connected to the threads of the two movable upright plates 214, which controls the two clamping plates 215 to move closer to each other on the top of the license plate placement plate 21 until the license plate is clamped and fixed. This allows for the rapid processing of longer license plates. The system quickly fixes new energy vehicle license plates and shorter fuel vehicle license plates. First, the hydraulic cylinder 32 drives the pressure plate 33 to descend slightly under the control of a proportional valve until the drill rods 35 of the output shafts of the two drilling motors 34 engage with the rear positioning holes 27 of the drilling positioning plate 26, achieving positioning. During descent, the pressure plate 33 remains stable by sliding the limit slide rod 36 against the horizontal position of the portal plate 31. Then, the servo motor 23, powered by the starter wire, drives the positive and negative threaded rod 24 within the positioning drive frame 22 to rotate, coordinating with the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rod 24. The threaded connection between the textured wall and the adjusting movable plate 25 allows control of the two adjusting movable plates 25 to drive the two drilling positioning plates 26 to move relative to each other. An encoder can precisely control the servo motor 23 to achieve precise positioning of the positioning hole 27. Since the drill rod 35 is located inside the positioning hole 27, adjusting the positioning hole 27 can directly drive the two drilling motors 34 to slide synchronously on the outer wall of the slide rod 332 within the slide groove 331 using the motor slider 333. After adjustment, the hydraulic cylinder 32 and the two drilling motors 34 can be activated, thereby driving the pressure plate 33 and the two drill rods 35 through the positioning hole 27. 7. Drill holes in the license plates. After drilling the two holes on the back, drive the drill rod 35 to rise and slightly disengage from the positioning hole 27. Then, quickly start the electric push rod 29 to fully retract the output end, which will move the license plate placement plate 21 backward, so that the drill rod 35 is aligned with the positioning hole 27 on the front. Similarly, press down to pass through the drill hole, thereby realizing the rapid positioning and drilling of different holes for different license plates. The debris generated during drilling will fall directly into the debris collection drawer 14 in the collection box 13 through the debris fallout through hole 28 and through hole 12 for collection. When cleaning is needed, simply pull out the debris collection drawer 14.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
