Description

TECHNICAL FIELD

[0001] The utility model relates to the auxiliary equipment of blade processing, specifically a visual blade edge angle tester. BACKGROUND

[0002] It is known in the field of blade processing that the blade needs to be sampled to detect whether the blade edge angle meets the specification requirement after the cutting edge is processed, at which time the blade edge angle tester needs to be used.

[0003] The traditional blade edge angle tester comprises a base, the base is provided with a box, the inner side wall of the box is provided with a transversely arranged strip hole, the box is provided with a testing shaft, one end of the testing shaft extends out of the strip hole, the box is provided with a translation operating mechanism for controlling the horizontal movement of the testing shaft in the strip hole; the testing shaft is fixedly connected with a testing rod at the end outside the box, the testing rod is perpendicular to the testing shaft, and the outer end of the testing rod is provided with a blade clamp; a plane is formed on the upper part of the rotating end of the testing rod, and a level is placed on the plane; a testing table is arranged on the base corresponding to one end of the box, and the testing table is connected with the base through a lifting fine adjustment mechanism; the testing table is provided with a plastic roller, and the blade clamp at the outer end of the testing rod is located above the plastic roller. When testing, the blade to be tested is clamped by the blade clamp on the testing rod, and the testing rod is rotated downward, so that the cutting edge of the blade falls on the plastic roller of the testing table, then the lifting fine adjustment mechanism is adjusted to slightly lift the testing table, and the translation operating mechanism is adjusted at the same time, the testing shaft drives the testing rod and the blade to slide forward and backward on the plastic roller, and the fitting degree of the inclined surface of the blade cutting edge and the plastic roller is judged by the resistance felt by hand, when the inclined surface of the blade cutting edge is completely fitted with the plastic roller, the angle displayed on the level at this time is the blade edge angle of the blade. The fitting degree of the inclined surface of the blade cutting edge and the plastic roller is judged by the manual feeling of the operator, which is greatly affected by human factors, and the measurement error is also large. At the same time, the data measured by the blade edge angle tester needs to be recorded manually, which is easy to make mistakes and difficult to process digitally, and is not suitable for large-scale production and defective product tracing. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at solving the defects of the prior art, and provides a visual blade edge angle tester, which can magnify and display the sliding state of the blade cutting edge on the plastic roller, does not need to be judged by manual feeling, can reduce the influence of human factors and measurement error, and can display and record the measurement data on the industrial computer, so that recording errors do not occur, digital processing is possible, and large-scale production and defective product tracing are suitable.

[0005] To solve the above problems, the following technical solutions are adopted:

[0006] This utility model discloses a visual blade angle tester, comprising a base with an L-shaped housing. The vertical part of the housing serves as the operating section, with horizontally arranged strip-shaped holes on its inner sidewall. A test shaft is located within the operating section, with one end extending from the strip-shaped holes. A translation mechanism within the operating section controls the horizontal movement of the test shaft within the strip-shaped holes. A test rod is fixedly connected to the outer end of the test shaft, perpendicular to the test shaft, with a blade clamp at its outer end. A test platform is mounted on the base corresponding to the outer end of the operating section, connected to the base via a lifting and fine-tuning mechanism. Plastic rollers are mounted on the test platform, and the blade clamp at the outer end of the test rod rests on these rollers. The key feature is that the horizontal part of the housing serves as a display section, with a square hole on its side. An industrial control computer is located within the display section, with its display screen adapted to the square hole. An encoder is connected to the test shaft within the operating section, and this encoder is electrically connected to the industrial control computer. The upper end of the operating part of the box has a rotating frame that can rotate in a plane, and a vertically arranged electronic magnifying glass is fixed at the outer end of the rotating frame. The electronic magnifying glass is electrically connected to the industrial control computer.

[0007] Furthermore, the display section of the enclosure contains a printer, which is electrically connected to the industrial control computer.

[0008] The translation operation mechanism includes a vertically arranged fixed support plate located within the operating section of the housing, with its bottom fixedly connected to the base. A horizontally arranged slide rail is located on the side of the fixed support plate, and a slider is connected to the slide rail. A movable support plate is fixed to the slider. The fixed support plate has a through hole containing an operating shaft, which is circumferentially and axially fixedly engaged with the fixed support plate. A gear is fixedly connected to one end of the operating shaft corresponding to the slide rail, and a horizontally arranged rack is connected to the lower end of the movable support plate, meshing with the gear. One end of the operating shaft, facing away from the slide rail, extends outward from the operating section of the housing and is connected to a translation knob. The movable support plate has a through hole, and a test shaft is located within this through hole, with the test shaft circumferentially and axially fixedly engaged with the movable support plate. The inner end of the test shaft extends from a slotted hole in the operating section of the housing and is connected to the test rod, while the outer end of the test shaft is connected to the encoder.

[0009] The rotating frame includes a column, the lower end of which is fixedly connected to the housing. A rotating arm is mounted on the column, and the rotating arm is in a damped rotational engagement with the column. The electronic magnifying glass is fixed to the outer end of the rotating arm.

[0010] The test platform is flat, with a U-shaped notch at one end corresponding to the test rod. The plastic roller is located within this U-shaped notch and is rotatably engaged with the test platform via a pivot. The plastic roller is positioned directly below the test rod blade holder.

[0011] The lifting and fine-tuning mechanism includes a fixed base and a lifting base. The fixed base is fixedly connected to the base, and the top of the lifting base is fixedly connected to the bottom surface of the test platform. The fixed base has a vertically arranged guide sleeve containing a guide post, the upper end of which is fixedly connected to the bottom surface of the test platform. The fixed base has a threaded hole containing a bolt. The upper end of the bolt is circumferentially and axially fixedly engaged with the lifting base, and a lifting knob is fixedly connected to the bolt.

[0012] In the above solution, the four corners of the bottom of the base are equipped with leveling feet.

[0013] The base has a storage drawer at its bottom.

[0014] The above approach has the following advantages:

[0015] The visual blade angle tester of this invention has a square hole on the side of the display unit. An industrial control computer is located inside the display unit, and its screen is adapted to the square hole. An encoder is connected to the test shaft inside the operating unit, and this encoder is electrically connected to the industrial control computer. A rotating frame is located at the top of the operating unit, allowing rotation in a plane. A vertically arranged electronic magnifying glass is fixed to the outer end of the rotating frame and is electrically connected to the industrial control computer. Before testing, the reference position is zeroed out by rotating the test rod to a horizontal position, placing a level on it, adjusting the test rod until the level displays 0 degrees, and then using the encoder to adjust the display data of the industrial control computer to match the data displayed by the level. During testing, the blade to be tested is held in place by the blade clamp on the testing rod, and the testing rod is rotated downwards so that the blade's cutting edge rests on the plastic roller of the testing platform. Simultaneously, the electronic magnifying glass is rotated to directly above the blade's cutting edge. Then, the lifting and fine-tuning mechanism is adjusted to slightly raise and lower the testing platform, while the translation mechanism is adjusted simultaneously. The testing shaft drives the testing rod and the blade, causing the blade's cutting edge to slide back and forth on the plastic roller. During the test, the contact between the blade's bevel and the plastic roller is magnified by the electronic magnifying glass and displayed on the industrial control computer screen. If the blade's bevel is not fully in contact with the plastic roller, debris will be scraped off the plastic roller during the back-and-forth sliding process. The operator can clearly see this and adjust the height of the testing platform to ensure complete contact between the blade's bevel and the plastic roller, preventing further debris scraping. The angle displayed on the industrial control computer at this point is the blade's cutting edge angle. Using this visual blade angle tester eliminates the need for manual judgment, reducing the influence of human factors and minimizing measurement errors. Meanwhile, the data measured by this visual blade angle tester can be converted into digital signals by an encoder and transmitted to an industrial control computer, where it can be displayed and recorded. This eliminates recording errors and allows for digital processing, making it suitable for large-scale production and the traceability of defective products. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] likeFigure 1 As shown, the visual blade angle tester of this utility model includes a base 1 with an L-shaped box on it. The vertical part of the box is the operating part, and its inner side wall has horizontally arranged strip holes 18. A test shaft 16 is located inside the operating part 121 of the box, with one end of the test shaft 16 extending out of the strip hole 18. The operating part 121 of the box has a translation operating mechanism for controlling the horizontal movement of the test shaft 16 within the strip hole 18. A test rod 15 is fixedly connected to one end of the test shaft 16 located outside the operating part 121 of the box. The test rod 15 is perpendicular to the test shaft 16, and a blade clamp 151 is provided at the outer end of the test rod 15. A test platform 8 is provided on the base 1 corresponding to the outer end of the operating part 121 of the box. The test platform 8 is connected to the base 1 by a lifting and fine-tuning mechanism. A plastic roller 9 is located on the test platform 8, and the blade clamp 151 at the outer end of the test rod 15 is located on the plastic roller 9. The horizontal section of the enclosure serves as a display unit, with a square hole on its side. An industrial computer 17 is housed within the display unit 122, and the display screen of the industrial computer 17 is adapted to the square hole. An encoder 26 is connected to the test shaft 16 within the enclosure's operating section 121, and this encoder 26 is electrically connected to the industrial computer 17. A rotating frame is located at the upper end of the enclosure's operating section 121, allowing rotation in a plane. A vertically arranged electronic magnifying glass 10 is fixed to the outer end of the rotating frame, and this electronic magnifying glass 10 is electrically connected to the industrial computer 17.

[0021] The display unit of the housing contains a printer 14, which is electrically connected to the industrial computer 17. Each of the four corners of the base 1 has a leveling foot 2. Adjusting these leveling feet 2 ensures that the upper surface of the base 1 is level, reducing measurement errors. A storage drawer 3 is located at the bottom of the base 1, which can be used to store auxiliary tools.

[0022] like Figure 2As shown, the translation operation mechanism includes a fixed support plate 20 located vertically within the operating section 121 of the housing, with its bottom fixedly connected to the base 1. A horizontally arranged slide rail 24 is located on the side of the fixed support plate 20, and a slider 25 is connected to the slide rail 24. A movable support plate 27 is fixedly mounted on the slider 25. The fixed support plate 20 has a through hole containing an operating shaft 23, which is circumferentially rotated and axially fixedly engaged with the fixed support plate 20. A gear 28 is fixedly connected to one end of the operating shaft 23 corresponding to the slide rail 24, and a horizontally arranged rack 21 is connected to the lower end of the movable support plate 27, meshing with the gear 28. One end of the operating shaft 23, facing away from the slide rail 24, extends outward from the operating section 121 of the housing, and a translation knob 22 is connected to it. The movable support plate 27 has a through hole, and the test shaft 16 is located in the through hole. The test shaft 16 and the movable support plate 27 are circumferentially rotated and axially fixed. The inner end of the test shaft 16 extends from the strip hole 18 of the housing operation part 121 and is connected to the test rod 15. The outer end of the test shaft 16 is connected to the encoder 26.

[0023] like Figure 1 As shown, the rotating frame includes a column 111, the lower end of which is fixedly connected to the housing. A rotating arm 112 is mounted on the column 111, and the rotating arm 112 is in a damped rotational engagement with the column 111. The electronic magnifying glass 10 is fixed to the outer end of the rotating arm 112.

[0024] The test platform 8 is flat, with a U-shaped notch 82 at one end corresponding to the test rod 15. The plastic roller 9 is located within the U-shaped notch 82, and the plastic roller 9 is rotatably engaged with the test platform 8 via a pivot. The plastic roller 9 is located directly below the blade holder 151 of the test rod 15.

[0025] The lifting and fine-tuning mechanism includes a fixed base 6 and a lifting base 7. The fixed base 6 is fixedly connected to the base 1, and the top of the lifting base 7 is fixedly connected to the bottom surface of the test platform 8. The fixed base 6 has a vertically arranged guide sleeve 61, and a guide post 81 is located inside the guide sleeve 61. The upper end of the guide post 81 is fixedly connected to the bottom surface of the test platform 8. The fixed base 6 has a threaded hole, and a bolt 4 is located inside the threaded hole. The upper end of the bolt 4 is circumferentially rotated and axially fixedly engaged with the lifting base 7, and a lifting knob 5 is fixedly connected to the bolt 4.

[0026] Before testing the blade angle, the reference position of the visual blade angle tester of this utility model needs to be zeroed. That is, rotate the test rod 15 to a horizontal position, place the level 13 on it, adjust the test rod 15 so that the data displayed by the level 13 is 0 degrees, and then use the encoder 26 to adjust the display data of the industrial control computer 17 so that it is consistent with the data displayed by the level 13.

[0027] During testing, such as Figure 3 As shown, the blade clamp 151 on the test rod 15 holds the blade to be tested, and the test rod 15 is rotated downwards so that the cutting edge of the blade 19 falls on the plastic roller 9 of the test platform 8. At the same time, the electronic magnifying glass 10 is rotated to be directly above the cutting edge of the blade 19. Then, the lifting knob 5 is rotated to slightly raise and lower the test platform 8, and at the same time, the translation knob 22 is rotated. The test shaft 16 drives the test rod 15 and the blade 19, so that the cutting edge of the blade 19 slides back and forth on the plastic roller 9. During the test, the fit between the beveled edge of the blade 19 and the plastic roller 9 can be magnified by the electronic magnifying glass 10 and displayed on the screen of the industrial control computer 17. If the beveled edge of the blade 19 is not fully fitted with the plastic roller 9, the blade 19 will scrape debris off the plastic roller 9 during the back-and-forth sliding process. The operator can clearly see this and adjust the height of the test platform 8 to ensure that the beveled edge of the blade 19 is fully fitted with the plastic roller 9, preventing further debris scraping. The angle displayed on the industrial control computer 17 at this point is the blade angle of the blade 19. After the test is completed, the test data will be recorded in the storage space of the industrial control computer 17. If necessary, the test results can be printed using the printer 14 connected to the industrial control computer 17.

[0028] Therefore, using the visual blade angle tester of this invention to test the blade angle of the blade 19 allows for direct observation of the bevel surface of the blade 19's cutting edge and the fit between it and the plastic roller 9 on the display screen of the industrial control computer 17. This eliminates the need for manual judgment, reducing the influence of human factors and minimizing measurement errors. Furthermore, the data measured by this visual blade angle tester can be converted into digital signals by the encoder 26 and transmitted to the industrial control computer 17 for display and recording. This eliminates recording errors and allows for digital processing, making it suitable for large-scale production and the traceability of defective products.
