Description

Technical Field

[0001] This utility model relates to the technical field of coated cutting tools, specifically a brushing device for coated cutting tool samples. Background Technology

[0002] The coated cutting tool specimen brushing and grinding device is a device used to prepare and process coated tool specimens. Its main function is to brush and grind coated tools to evaluate the coating performance and the cutting performance of the tool.

[0003] According to Chinese Patent No. CN221936149U, a brushing device for a coated cutting tool sample includes a stand, a motor, a rotating shaft, insert plates, brush bristles, and a clamping mechanism. The stand has two parts, left and right. A motor is connected to the upper right side of the right stand, and a rotating shaft is connected to the motor's output shaft. The rotating shaft is rotatably connected to the stand. Three insert plates are detachably connected to the outside of the rotating shaft, each insert plate having multiple brush bristles attached. A clamping mechanism for holding a diamond-coated tool for brushing is rotatably connected to the upper part of the stand. The clamping mechanism includes a limit frame, a rotating arm, a telescopic arm, a lower clamping plate, a compression spring, and an upper clamping plate. The lower clamping plate is connected between the lower parts of the telescopic arms, and the upper clamping plate is slidably connected between the telescopic arms. The lower clamping plate engages with the upper clamping plate, and compression springs are connected between the upper clamping plate and the telescopic arms. When the diamond-coated tool is placed on the lower clamping plate, the upper clamping plate moves downwards under the action of the compression springs to engage with the lower clamping plate, thereby clamping the diamond-coated tool.

[0004] In the above scheme, the diamond-coated tool is clamped and fixed by the lower clamping plate and the upper clamping plate, and then the diamond-coated tool is brushed by rotating the bristles. This has the following disadvantages: when the brushing device is in use, the tool cannot rotate, so the bristles may only act on a part of the tool, thereby reducing the comprehensiveness and consistency of brushing. Utility Model Content

[0005] The purpose of this invention is to provide a brushing device for coated cutting tool samples, in order to solve the problem that when the tool cannot rotate during use, the brush bristles may only act on a part of the tool, thereby reducing the comprehensiveness and consistency of brushing.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a coating cutting tool sample brushing device, comprising a support plate, the support plate being fixed to the top surface of a base, a rotating hole being provided on one side of the support plate, a first drive motor being fixed to the rear side of the support plate, a turntable being fixed to the output shaft of the first drive motor, two connecting plates being fixed to the front side of the turntable, arc-shaped clamping plates being movably provided on the inner sides of the two connecting plates, rotating grooves being provided on the outer sides of the two arc-shaped clamping plates, first threaded holes being provided on the top surfaces of the two connecting plates, first bolts being threaded into the two first threaded holes, rotating blocks being fixed to one end of the two first bolts, and the two rotating blocks being rotatably disposed in the two rotating grooves, a U-shaped seat being movably provided above the base, a second drive motor being fixed to the right side of the outer wall of the U-shaped seat, a rotating roller being rotatably provided inside the U-shaped seat, the right end of the rotating roller being fixedly connected to the output shaft of the second drive motor, and a plurality of brush bristles being detachably provided on the outer wall of the rotating roller.

[0007] Preferably, the top surfaces of the two connecting plates are respectively provided with limiting holes, and limiting posts are slidably inserted into the two limiting holes. The inner ends of the two limiting posts are respectively fixedly connected to the outer sides of the two arc-shaped clamps.

[0008] Preferably, a fixing plate is fixed to the top surface of the base, and a hydraulic push rod is fixed to the rear side of the fixing plate. One end of the hydraulic push rod is fixedly connected to the front side of the outer wall of the U-shaped seat.

[0009] Preferably, the top surface of the base has two sliding grooves, and the bottom surface of the U-shaped base has two sliders fixed thereon, with the two sliders slidably disposed in the two sliding grooves respectively.

[0010] Preferably, a mounting plate is fixed to the inner side of each of the bristles, and a plurality of threaded grooves are provided on the outer wall of the roller. Each of the mounting plates has two second threaded holes, and a second bolt is threaded into each of the two second threaded holes. The threaded end of the second bolt is threaded into the inner thread of the threaded groove.

[0011] Preferably, a number of mounting plates are fixed to the inner side of each mounting plate, and a number of positioning grooves are provided on the outer wall of the rotating roller, with each positioning groove positioning a number of positioning blocks.

[0012] Compared with the prior art, the coating cutting tool sample brushing device using the above technical solution has the following beneficial effects:

[0013] In operation, the operator first places the diamond-coated tool in the lower arc-shaped clamping plate. Then, they rotate the two first bolts, causing the two rotating blocks to rotate within their respective rotating slots. This pushes the two arc-shaped clamping plates closer together, clamping and fixing the diamond-coated tool. After fixing, the operator starts the second drive motor, causing the rotating roller to drive several brush bristles to rotate and brush the diamond-coated tool. Simultaneously, the first drive motor is started, causing the turntable to rotate and brush the diamond-coated tool. By observing the wear of the tool, the strength and wear resistance of the coating can be confirmed, and the hardness, toughness, and wear resistance of the tool can be evaluated. Through the coordinated use of the connecting plate, arc-shaped clamping plate, first bolts, rotating blocks, second drive motor, rotating roller, and brush bristles, the clamping, fixing, and brushing of the diamond-coated tool are achieved. Furthermore, the coordinated use with the first drive motor and turntable ensures that the diamond-coated tool rotates evenly during the brushing process, guaranteeing comprehensive and consistent brushing, thus improving brushing efficiency and quality.

[0014] Second, during use, the combination of the limiting holes and limiting posts ensures that the arc-shaped clamp maintains linear movement during transport, preventing unnecessary rotation and thus improving clamping stability and accuracy. Adjusting the extension length of the hydraulic push rod controls the distance between the bristles and the tool, meeting various brushing needs. The combination of the sliding groove and the slider limits the movement of the U-shaped seat, ensuring smooth sliding on the base and preventing deviation or wobbling. This helps maintain stable contact between the bristles and the diamond-coated tool, improving the brushing effect.

[0015] Third, during use, staff can select appropriate brush bristles for brushing according to actual needs, improving the flexibility and applicability of the equipment. When installing new brush bristles, staff can align the positioning block on the mounting plate with the positioning groove on the rotating roller for initial positioning, and then rotate the second bolt to fix it. This ensures accurate correspondence between the threaded groove and the second threaded hole, improving the convenience and accuracy of installation. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a brushing device for coating cutting tool samples includes a support plate 1, which is fixed to the top surface of a base 2. A rotating hole 3 is provided on one side of the support plate 1. A first drive motor 4 is fixed to the rear side of the support plate 1. A turntable 5 is fixed to the output shaft of the first drive motor 4. Two connecting plates 6 are fixed to the front side of the turntable 5. Arc-shaped clamping plates 7 are movably arranged on the inner sides of the two connecting plates 6, and rotating grooves 8 are provided on the outer sides of the two arc-shaped clamping plates 7. First threaded holes 9 are provided on the top surfaces of the two connecting plates 6. A first bolt 10 is threaded into a threaded hole 9. A rotating block 11 is fixed to one end of each of the two first bolts 10. The two rotating blocks 11 are rotatably arranged in two rotating slots 8. A U-shaped seat 12 is movably arranged above the base 2. A second drive motor 13 is fixed to the right side of the outer wall of the U-shaped seat 12. A rotating roller 14 is rotatably arranged inside the U-shaped seat 12. The right end of the rotating roller 14 is fixedly connected to the output shaft of the second drive motor 13. Several bristles 15 are detachably arranged on the outer wall of the rotating roller 14.

[0023] In use, the operator first places the diamond-coated tool in the lower arc-shaped clamp 7, then rotates the two first bolts 10, causing the two rotating blocks 11 to rotate inside the two rotating slots 8 respectively. This pushes the two arc-shaped clamps 7 closer together, clamping and fixing the diamond-coated tool. After fixing, the operator starts the second drive motor 13, causing the rotating roller 14 to drive several brush bristles 15 to rotate and brush the diamond-coated tool. At the same time, the first drive motor 4 is started, causing the turntable 5 to rotate and brush the diamond-coated tool. By observing the wear of the tool, the strength and wear resistance of the coating can be confirmed, and the hardness, toughness, and wear resistance of the tool can be evaluated.

[0024] The use of connecting plate 6, arc-shaped clamping plate 7, first bolt 10, rotating block 11, second drive motor 13, rotating roller 14 and brush bristles 15 enables the clamping, fixing and brushing of diamond-coated tools. At the same time, the use of first drive motor 4 and turntable 5 enables the diamond-coated tools to rotate evenly during the brushing process, ensuring the comprehensiveness and consistency of brushing and improving brushing efficiency and quality.

[0025] like Figures 1-3 As shown, the top surfaces of the two connecting plates 6 are respectively provided with limiting holes 16, and limiting posts 17 are slidably inserted into the two limiting holes 16 respectively. The inner ends of the two limiting posts 17 are respectively fixedly connected to the outer sides of the two arc-shaped clamps 7.

[0026] In use, the cooperation between the limiting hole 16 and the limiting post 17 helps to ensure that the arc-shaped clamp 7 maintains linear movement during movement, preventing unnecessary rotation, thereby improving the stability and accuracy of clamping.

[0027] like Figure 1 and Figure 2 As shown, a fixing plate 18 is fixed on the top surface of the base 2, and a hydraulic push rod 19 is fixed on the rear side of the fixing plate 18. One end of the extension rod of the hydraulic push rod 19 is fixedly connected to the front side of the outer wall of the U-shaped seat 12. Two sliding grooves 20 are opened on the top surface of the base 2, and two sliders 21 are fixed on the bottom surface of the U-shaped seat 12. The two sliders 21 are slidably arranged in the two sliding grooves 20 respectively.

[0028] During use, the operator activates the hydraulic push rod 19, allowing the U-shaped seat 12 and its roller 14 and bristles 15 to move back and forth. By adjusting the extension length of the hydraulic push rod 19, the distance between the bristles 15 and the tool can be controlled, thus meeting different brushing and polishing needs. The cooperation between the slide groove 20 and the slider 21 helps to limit the movement of the U-shaped seat 12, ensuring that the U-shaped seat 12 slides smoothly on the base 2, preventing it from shifting or shaking. This helps to maintain stable contact between the bristles 15 and the diamond-coated tool, improving the brushing and polishing effect.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, mounting plates 22 are fixed to the inner sides of several bristles 15 respectively. Several threaded grooves 23 are opened on the outer wall of the roller 14. Two second threaded holes 24 are opened on each of the mounting plates 22. Second bolts 25 are threaded into the two second threaded holes 24 respectively. The threaded end of the second bolt 25 is threaded into the inside of the threaded groove 23. Positioning blocks 26 are fixed to the inner sides of several mounting plates 22 respectively. Several positioning grooves 27 are opened on the outer wall of the roller 14. Several positioning grooves 27 respectively position several positioning blocks 26.

[0030] During use, when replacing the brush bristles 15, the operator can first remove the second bolt 25, remove the mounting plate 22 and its brush bristles 15 from the rotating roller 14, then align the new mounting plate 22 and its brush bristles 15 with the threaded groove 23, and fix it with the second bolt 25. This helps the operator select the appropriate brush bristles 15 for brushing according to actual needs, improving the flexibility and applicability of the equipment. When installing new brush bristles 15, the operator can align the positioning block 26 on the mounting plate 22 with the positioning groove 27 on the rotating roller 14 for initial positioning, and then rotate the second bolt 25 to fix it. This ensures the accurate correspondence between the threaded groove 23 and the second threaded hole 24, improving the convenience and accuracy of installation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
