Description

Technical Field

[0001] This utility model relates to the field of tool polishing technology, and more specifically, to a polishing structure for cemented carbide tools. Background Technology

[0002] Carbide cutting tools are key tools in the field of mechanical manufacturing. They are mainly composed of high-hardness refractory metal carbides, supplemented with binders such as cobalt and nickel, and are manufactured through ball milling, pressing, and sintering processes. They possess excellent properties such as high hardness, strong wear resistance, and good heat resistance. These tools are widely used in CNC machine tools and are core components of metal cutting processes. They perform particularly well in high-density, high-strength, and high-temperature environments, such as in mining engineering, automotive manufacturing, and aerospace. Polishing carbide cutting tools can reduce cutting resistance, improve the surface quality of the machined surface, enhance chip removal capabilities, extend tool life, and reduce micro-chipping. Belt grinding and roller polishing are common polishing methods.

[0003] Most existing carbide tool polishing structures are equipped with grinding mechanisms in fixed positions and at fixed angles. During use, the sanding belt and roller are in relatively fixed positions, and users rely on themselves to finely adjust the position of the carbide and the feed tool and the grinding and polishing angle. However, carbide tools have many variations in shape and size, requiring more and larger adjustments during the grinding process, resulting in poor flexibility and a higher burden on users.

[0004] In summary, to address the issue of excessive user burden and reduced flexibility during the polishing and grinding of carbide cutting tools, it is necessary to improve the polishing structure of carbide cutting tools by enabling flexible adjustment of the contact point and angle between the polishing structure and the tool, thereby enhancing usability. Utility Model Content

[0005] The problem to be solved by the carbide tool polishing structure provided by this utility model is that the existing carbide tool polishing structure has a relatively fixed position for the abrasive belt and roller, while the shape and specifications of carbide tools vary greatly, requiring more and larger adjustments during the polishing process, which puts a heavy burden on the user.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cemented carbide tool polishing structure, including a support platform, a first threaded rod rotatably connected to the inner side of the support platform, a first support frame provided at the upper end of the first threaded rod, the first support frame being fixedly connected to the support platform, a first rotating roller rotatably connected to the inner side of the first support frame, a fixed frame fixedly connected to the upper end of the support platform, a second support frame threadedly connected to the outer side of the first threaded rod, the second support frame being slidably connected to the support platform, a second rotating roller rotatably connected to the inner side of the second support frame, a first motor mounted on the outer side of the second support frame, the output end of the first motor being fixedly connected to the second rotating roller, a polishing belt for tool polishing provided on the outer side of the first and second rotating rollers, and an adjustment structure for adjusting the height of the polishing belt provided on the inner side of the fixed frame.

[0007] In a preferred embodiment, the adjustment structure includes a third support frame slidably connected to the inside of the fixed frame, a third rotating roller rotatably connected to the inside of the third support frame, and a support spring installed between the third support frame and the fixed frame.

[0008] In a preferred embodiment, a hydraulic push rod is installed on the outer side of the support platform, and a movable platform is fixedly connected to the output end of the hydraulic push rod. The hydraulic push rod is used to drive the movable platform to move along a predetermined path, and a grinding roller is rotatably connected to the inner side of the movable platform.

[0009] In a preferred embodiment, a first gear is fixedly connected to the outer side of the grinding roller, and a second motor is mounted on the outer side of the moving table. A second gear is fixedly connected to the output end of the second motor. The second motor is used to drive the second gear to rotate, and the second gear meshes with the first gear.

[0010] In a preferred embodiment, a rotating platform is provided at the upper end of the hydraulic push rod, the rotating platform is rotatably connected to the support platform, a support body is rotatably connected to the upper end of the rotating platform, and a docking frame is rotatably connected to the outer side of the support body.

[0011] In a preferred embodiment, a second threaded rod is fixedly connected to the inner side of the docking frame, a movable frame is slidably connected to the outer side of the second threaded rod, a rotating tube is rotatably connected to the inner side of the movable frame, the rotating tube is threadedly connected to the second threaded rod, and a fixing bolt is provided at the lower end of the movable frame.

[0012] In a preferred embodiment, the lower end of the support platform is rotatably connected to the base body, and the outer side of the base body is provided with limit bolts.

[0013] The beneficial effects of this utility model are as follows: This invention uses a first motor to drive a second rotating roller to rotate, which in turn works with a first support frame and the first rotating roller to drive a grinding belt to grind carbide tools. A first threaded rod drives the second support frame and the second rotating roller to move, thereby loosening or tightening the grinding belt. At the same time, a support spring drives a third support frame and a third rotating roller to lift, which in turn tightens the grinding belt and adjusts the tilt angle.

[0014] This invention uses a second motor to drive a second gear to rotate, which in turn works with a first gear to drive a grinding roller to grind the tool. The base body facilitates the rotation of the support platform and is fixed with limit bolts, allowing for quick tool changes and user convenience. Simultaneously, fixed bolts secure the carbide tool, and a rotating tube, in conjunction with a second threaded rod, moves the moving frame and the carbide tool, improving grinding flexibility. A connecting frame, in conjunction with the rotating platform and the support body, adjusts the position and tilt of the moving frame, thereby changing the position and tilt of the tool.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 A polishing structure for cemented carbide tools includes a support platform 1. A first threaded rod 2 is rotatably connected to the inner side of the support platform 1. A first support frame 3 is provided at the upper end of the first threaded rod 2. The first support frame 3 is fixedly connected to the support platform 1. A first rotating roller 4 is rotatably connected to the inner side of the first support frame 3. A fixing frame 5 is fixedly connected to the upper end of the support platform 1. A second support frame 6 is threadedly connected to the outer side of the first threaded rod 2. The second support frame 6 is slidably connected to the support platform 1. A second rotating roller 7 is rotatably connected to the inner side of the second support frame 6. A first motor 8 is installed on the outer side of the second support frame 6. The output end of the first motor 8 is fixedly connected to the second rotating roller 7. A polishing belt 9 for tool polishing is provided on the outer side of the first rotating roller 4 and the second rotating roller 7. An adjustment structure for adjusting the height of the polishing belt 9 is provided on the inner side of the fixing frame 5.

[0023] It should be noted that the first motor 8 drives the second roller 7 to rotate, which in turn works with the first support frame 3 and the first roller 4 to drive the grinding belt 9 to grind the carbide tool. The first threaded rod 2 drives the second support frame 6 and the second roller 7 to move, thereby loosening or tightening the grinding belt 9.

[0024] It is worth noting that the position of the first support frame 3 is fixed, while the second support frame 6 and the second rotating roller 7 move along the first threaded rod 2. At the same time, the adjusting structure can tighten the loosened grinding belt 9, thereby adjusting the inclination angle of the grinding belt 9.

[0025] Refer to the instruction manual appendix Figure 2 The adjustment structure includes a third support frame 10 that is slidably connected to the inside of the fixed frame 5, a third roller 11 that is rotatably connected to the inside of the third support frame 10, and a support spring 12 installed between the third support frame 10 and the fixed frame 5.

[0026] It should be noted that a telescopic rod is provided on the inner side of the support spring 12, which allows the fixed frame 5 to move up and down smoothly. The retraction of the support spring 12 pulls the third support frame 10 and the third rotating roller 11 to lift, thereby driving the grinding belt 9 to tighten and adjust the tilt angle, and reducing the possibility of the grinding belt 9 deviating during the grinding process. At the same time, the support spring 12 enables the grinding belt 9 to have a certain retraction ability, reducing the possibility of damage to the grinding belt 9 when the alloy tool approaches too quickly or with too much force.

[0027] Refer to the instruction manual appendix Figure 3A hydraulic push rod 13 is installed on the outer side of the support platform 1. A movable platform 14 is fixedly connected to the output end of the hydraulic push rod 13. The hydraulic push rod 13 is used to drive the movable platform 14 to move along a predetermined path. A grinding roller 15 is rotatably connected to the inner side of the movable platform 14.

[0028] It should be noted that the grinding roller 15 is moved by the hydraulic push rod 13, thereby adjusting the grinding position and improving the grinding effect of the tool in different postures.

[0029] Refer to the instruction manual appendix Figure 3 A first gear 16 is fixedly connected to the outer side of the grinding roller 15, and a second motor 17 is installed on the outer side of the moving table 14. A second gear 18 is fixedly connected to the output end of the second motor 17. The second motor 17 is used to drive the second gear 18 to rotate, and the second gear 18 meshes with the first gear 16.

[0030] It should be noted that the second motor 17 drives the second gear 18 to rotate, which in turn cooperates with the first gear 16 to drive the grinding roller 15 to rotate in order to grind the tool.

[0031] Refer to the instruction manual appendix Figure 4 The upper end of the hydraulic push rod 13 is provided with a rotating platform 19, which is rotatably connected to the support platform 1. The upper end of the rotating platform 19 is rotatably connected to the support body 20, and the outer side of the support body 20 is rotatably connected to the docking frame 21.

[0032] It should be noted that the position and tilt angle of the docking frame 21 can be adjusted by rotating the table 19 and the support body 20.

[0033] Refer to the instruction manual appendix Figure 4 The inner side of the docking frame 21 is fixedly connected to a second threaded rod 22, and the outer side of the second threaded rod 22 is slidably connected to a movable frame 23. The inner side of the movable frame 23 is rotatably connected to a rotating tube 24, which is threadedly connected to the second threaded rod 22. The lower end of the movable frame 23 is provided with a fixing bolt 25.

[0034] It should be noted that the carbide tool is fixed by the fixing bolt 25, and the moving frame 23 and the carbide tool are moved by the rotating tube 24 in conjunction with the second threaded rod 22, thereby improving the flexibility during grinding.

[0035] Refer to the instruction manual appendix Figure 5 The lower end of the support platform 1 is rotatably connected to the base body 26, and the outer side of the base body 26 is provided with limit bolts 27.

[0036] It should be noted that the base body 26 facilitates the rotation of the support platform 1 and is fixed by the limit bolts 27, thereby enabling quick replacement of grinding tools.

[0037] It is worth noting that a positioning groove is provided on the second threaded rod 22, which allows the moving frame 23 to only translate on the second threaded rod 22 without rotating. A handle for moving and positioning is installed on the outside of the moving frame 23, which facilitates adjusting the tool's tilt angle in conjunction with the rotating table 19 and the support body 20 while adjusting the tool's position. At the same time, the moving frame 23 and the support body 20 enable the tool to align with the grinding roller 15, so that the hydraulic push rod 13 drives the grinding roller 15 to move and quickly grind a large flat area of ​​the tool.

[0038] Working principle: First, the first motor 8 drives the second roller 7 to rotate, which in turn works with the first support frame 3 and the first roller 4 to drive the grinding belt 9 to grind the carbide tool. Next, the first threaded rod 2 can be manually rotated for fine adjustment, which moves the second support frame 6 and the second roller 7 to loosen or tighten the grinding belt 9. Then, the support spring 12 drives the third support frame 10 and the third roller 11 to lift, which in turn tightens the grinding belt 9 and adjusts the tilt angle. Finally, the second motor 17 drives the second gear 18 to rotate, which in turn works with the first gear 16 to drive the grinding roller 15 to rotate to grind the tool. In use, firstly, the carbide tool is fixed by fixing bolt 25, and the moving frame 23 and the carbide tool are moved by rotating tube 24 in conjunction with second threaded rod 22, thereby improving the flexibility during grinding. Next, the position and tilt angle of the moving frame 23 are adjusted by connecting frame 21 in conjunction with rotating table 19 and support body 20, thereby changing the position and tilt angle of the tool. Then, the base body 26 facilitates the rotation of support table 1 and is fixed by limit bolt 27, thereby quickly changing grinding tools and facilitating user operation. Finally, the grinding roller 15 is moved by hydraulic push rod 13, thereby adjusting the grinding position and improving the grinding effect of different tool postures.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
