Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a grinding machine with easily detachable blades and grinding wheels. Background Technology

[0002] The main function of a tool sharpening machine is to restore and maintain the sharpness of tools, improve tool life and processing efficiency. Through precise grinding processes, the tool sharpening machine removes the worn parts on the tool surface, restores its original sharpness, and ensures that the tool can cut materials efficiently and accurately during processing. In addition, the tool sharpening machine can also optimize the cutting performance of the tool, reduce energy loss during the cutting process, and improve overall production efficiency.

[0003] Sharpening machines primarily optimize blade performance by using a motor to drive a grinding wheel. During long-term use, the grinding wheel wears down and needs periodic replacement. Existing grinding wheels are typically fixed to the motor's output shaft via a coupling. Disassembling the grinding wheel requires removing the positioning bolts on the coupling surface and then removing the grinding wheel from the motor's output shaft. However, grinding wheels are generally heavy, requiring one person to hold the wheel while another performs the installation or removal. This two-person operation, coupled with the limited operating space of existing sharpening machines, makes this method inefficient and increases the risk of the grinding wheel falling and injuring workers. Installing the blades to be sharpened is also cumbersome. Due to the blade's length, multiple mounting brackets are needed to secure it at various points to prevent breakage due to vibration during sharpening. Tightening multiple mounting brackets requires tightening bolts, which takes considerable time, wasting significant time during blade installation and removal. Utility Model Content

It includes a sharpening machine body 1, supporting feet 2, and a control panel 3. It also includes a moving module 4, a motor 5, and a grinding wheel 7. The supporting feet 2 are fixedly connected to the lower end of the sharpening machine body 1. The control panel 3 is fixedly installed on one side of the sharpening machine body 1. The moving module 4 is slidably connected to the upper end of the sharpening machine body 1. The motor 5 is fixedly installed on the upper end of the moving module 4. A coupling 6 is fixedly connected to the output end of the motor 5. The grinding wheel 7 is fixedly connected to one end of the coupling 6. A disassembly / assembly mechanism is provided on one side of the sharpening machine body 1. The grinding wheel 7 has a mounting and disassembly assembly. The upper end of the sharpening machine body 1 is equipped with a fixing assembly for fixing and installing the blade. This assembly includes a rotating plate 23, which is located on one side of the sharpening machine body 1. A slide rail 25 is fixedly connected to the upper end of the rotating plate 23, and a slider 26 is slidably connected to the upper surface of the slide rail 25. A fixing plate 31 is fixedly installed at the upper end of the sharpening machine body 1, and a fixing frame 30 is fixedly installed between the two fixing plates 31. A rotating seat 29 is fixedly connected to the end of the fixing frame 30. The rotating plate 23 is rotatably connected to the rotating seat 29. The fixing plate 31 is adapted to the rotating plate 23, and the slider... The upper surface of slider 26 is arc-shaped. Slider 26 is used to hold grinding wheel 7. The arc-shaped upper surface of slider 26 is in contact with the surface of grinding wheel 7. A pusher 27 is fixedly connected to one side of slider 26. The upper end of pusher 27 is threadedly connected to positioning handle 28 for fixing the position of slider 26. A grip 24 for rotating rotating plate 23 is fixedly connected to one side of rotating plate 23. When in use, the fixing assembly of this sharpening machine uses electric cylinder 10 to drive multiple sets of clamping blocks 12 to fix the blade at various points simultaneously. It is suitable for the installation and fixing of various types of blades. Compared with fixing blades by tightening bolts one by one, this method is more efficient. This design, while ensuring stability, greatly improves the efficiency of blade assembly and disassembly. The blade angle can be adjusted as needed to ensure optimal grinding results. The assembly and disassembly components of this sharpening machine utilize a slider 26 to assist in the assembly and disassembly of the grinding wheel 7. By providing a movable support base for the grinding wheel 7, the inconvenience caused by its heavy weight is avoided. The entire process can be completed by one person, significantly improving efficiency. The machine offers ample operating space and reduces the risk of accidents. When not in use, the rotating plate 23 can be folded, saving space and not affecting the normal operation of the sharpening machine body 1.

[0024] Please see Figure 3 - Figure 6In this embodiment, the fixing assembly includes a clamping plate 8, which is rotatably disposed within the main body 1 of the sharpening machine. Openings are evenly distributed on the surface of the clamping plate 8. A mounting plate 9 is fixedly installed at each opening on the surface of the clamping plate 8. An electric cylinder 10 is fixedly installed at the lower end of the mounting plate 9. The output end of the electric cylinder 10 passes through the mounting plate 9 and is fixedly connected to a top block 18. A fixing seat 11 is fixedly connected to the upper end of the mounting plate 9. A limiting block 14 is provided within the fixing seat 11. A clamping block 12 is slidably connected between two limiting blocks 14. One side of the clamping block 12 is fixedly connected to... The anti-slip pad 13 and the fixed base 11 have openings on both sides. A sliding rod 15 is fixedly connected to each opening on both sides of the fixed base 11. Push blocks 16 are provided on both sides of the clamping block 12, and the push blocks 16 are slidably connected to the sliding rod 15. A spring 17 is fitted onto the surface of the sliding rod 15. The lower end of the clamping block 12 is an inclined surface, and the upper end of the top block 18 is also an inclined surface. The lower inclined surface of the clamping block 12 contacts the upper inclined surface of the top block 18, and the clamping block 12 is used to push the top block 18 to move. One end of the clamping plate 8 has a rotating shaft that passes through the main body 1 of the sharpening machine. A worm gear 19 is fixedly connected to one end of the rotating shaft of the clamping plate 8. The main body 1 of the sharpening machine... A bearing seat 20 is fixedly installed on one side of the blade. A worm gear 21 is rotatably connected to one side of the bearing seat 20. The worm gear 21 meshes with a worm wheel 19. A rotating handle 22 is fixedly connected to one end of the worm gear 21. First, the blade is placed between the fixed seat 11 and the clamping plate 8. Then, the electric cylinder 10 is activated to move the top block 18 upward. The inclined surface at the upper end of the top block 18 presses against the inclined surface at the lower end of the clamping block 12, causing the clamping block 12 and the clamping plate 8 to clamp and fix the blade together. Multiple sets of clamping blocks 12 are provided to fix the blade in various places, ensuring the stability of the blade. Grinding is completed. Then, the electric cylinder 10 is activated again to lower the top block 18. The clamping block 12 loses the support of the top block 18, and the spring 17 pushes the clamping block 12 to move inward. At this time, the blade can be removed. Compared with the existing fixing method, the disassembly and assembly efficiency is greatly improved. When it is necessary to adjust the grinding angle of the blade, rotate the handle 22. Rotating the handle 22 drives the worm 21 to rotate at the bearing seat 20. The worm wheel 19, which is meshed with the worm 21, rotates at the same time. The worm wheel 19 is fixedly connected to the rotating shaft of the clamping plate 8. In this way, the blade fixedly installed at the clamping plate 8 can achieve angle adjustment.

[0025] In use, first, install the blade to be sharpened inside the main body 1 of the sharpening machine, place the blade between the fixed seat 11 and the clamping plate 8, and then start the electric cylinder 10. The electric cylinder 10 drives the top block 18 to move upward. The inclined surface at the upper end of the top block 18 presses the inclined surface at the lower end of the clamping block 12, causing the clamping block 12 to move outward. The clamping block 12 and the clamping plate 8 together clamp and fix the blade. There are multiple sets of clamping blocks 12, which fix the blade in various places to ensure the stability of the blade. After sharpening is completed, start the electric cylinder 10 again to make the top block 18 descend. The clamping block 12 loses the support of the top block 18, and the spring 17 pushes the push blocks 16 on both sides of the clamping block 12, so that the clamping block 12 moves inward into the fixed seat 11. At this time, the blade can be removed. Compared with the existing fixing method, the disassembly and assembly efficiency is greatly improved.

[0026] The limiting block 14 is slidably connected to the clamping block 12 to ensure the stability of the movement of the clamping block 12. An anti-slip pad 13 is fixedly connected to one side of the clamping block 12 to ensure that the blade does not shift during the grinding process.

[0027] When it is necessary to adjust the grinding angle of the blade, rotate the handle 22. Rotating the handle 22 will drive the worm 21 to rotate at the bearing seat 20. The worm wheel 19, which is meshed with the worm 21, will rotate at the same time. The worm wheel 19 is fixedly connected to the rotating shaft of the clamp plate 8. In this way, the blade fixedly installed at the clamp plate 8 can achieve angle adjustment.

[0028] The grinder uses a motor 5 to drive a grinding wheel 7 to grind the blades. A moving module 4 is used to reciprocate the grinding wheel 7. When the grinding wheel 7 needs replacement due to wear, first, control the moving module 4 to move it to one side of the grinder body 1. Then, grasp the handle 24 to rotate and unfold the rotating plate 23, which rotates at the rotating seat 29. Next, grasp the push handle 27 to move the slider 26. The slider 26 moves along the surface of the slide rail 25 until it is below the grinding wheel 7. Tighten the positioning handle 28 to fix the position of the slider 26. Then, remove the fixing bolts on the surface of the coupling 6, and then place the grinding wheel 7... Place the new grinding wheel 7 on the arc-shaped surface of the slider 26, loosen the positioning handle 28, and then pull the slider 26 outward to remove the grinding wheel 7. Place the new grinding wheel 7 on the slider 26, and then push the slider 26 inward. When one end of the grinding wheel 7 is inserted into the coupling 6, tighten the positioning handle 28 again to fix the position of the slider 26. Then install the grinding wheel 7 on the coupling 6 to complete the installation. The whole process can be completed by one person, which greatly improves efficiency. When not in use, the rotating plate 23 can be rotated and placed on the fixed frame 30 to complete the folding, thereby saving space and not affecting the normal use of the main body 1 of the sharpening machine.

[0029] Through the above steps, the fixing component of the sharpening machine, driven by the electric cylinder 10, simultaneously fixes the blade at various points by multiple sets of clamping blocks 12. While ensuring the stability of the fixation, it greatly improves the efficiency of blade assembly and disassembly. The blade angle can be adjusted as needed to ensure the grinding effect. The assembly and disassembly component of the sharpening machine provides a movable support base for the grinding wheel 7. The entire process can be completed by one person, greatly improving efficiency. The operating space is large, and safety accidents are less likely to occur. When not in use, the rotating plate 23 can be folded, thereby saving space and not affecting the normal use of the sharpening machine body 1.
