Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically a grinding wheel machine with a splash-proof safety protection structure. Background Technology

[0002] A grinding wheel machine is an important tool widely used in metal processing, machinery manufacturing and other industries. It mainly uses the high-speed rotation of the grinding wheel to grind, cut and polish workpieces, so that the workpieces achieve the required dimensional accuracy and surface quality.

[0003] While existing handheld grinders can perform grinding and polishing on workpieces, they cannot collect the debris generated during operation. As a result, the debris and dust generated when the grinding wheel comes into contact with the workpiece will radiate outwards during the high-speed rotation of the grinding wheel, threatening the personal safety of the operator. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a grinding wheel machine with a splash-proof safety protection structure. The dust collection device and the dust collection device can collect the debris generated during the operation of the grinding wheel machine and store it inside the collection device, thereby reducing the splashing of debris during the operation of the grinding wheel machine and improving the safety of the grinding wheel machine.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding wheel machine with a splash-proof safety protection structure, comprising: a grinding wheel machine body, a protective device fixedly connected to the outer wall of the grinding wheel machine body, a collecting device fixedly connected to the outer wall of the grinding wheel machine body, and a dust collection device externally mounted on the collecting device; the collecting device includes an air suction frame, a guide block fixedly connected to the inner wall of the air suction frame, a collecting frame fixedly connected to the side of the air suction frame away from the grinding wheel machine body, a limiting ring fixedly connected to the inner wall of the collecting frame, a ball bearing slidably connected to the inner wall of the limiting ring, a slider slidably connected to the outer wall of the collecting frame, and a spring fixedly connected to the inner wall of the slider; the dust collection device includes a mounting frame, a limiting groove clamped to the outer wall of the mounting frame, an impeller fixedly connected to the inner wall of the mounting frame, and a concave filter plate fixedly connected to the inner wall of the mounting frame. The dust collection device and the dust collection device together absorb the debris and dust generated during the operation of the grinding wheel machine body and store them inside the collecting device, avoiding the need for separate cleaning of debris and dust by workers after processing.

[0008] Preferably, the outer wall of the suction frame is fixedly connected to the outer wall of the protective device, and the end of the spring away from the slider is fixedly connected to the outer wall of the collection frame. The fixed connection between the spring, the slider, and the collection frame effectively prevents the slider from falling.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-11This utility model provides a technical solution: a grinding wheel machine with a splash-proof safety protection structure, comprising: a grinding wheel machine body 1, a protective device 2 fixedly connected to the outer wall of the grinding wheel machine body 1, a collecting device 3 fixedly connected to the outer wall of the grinding wheel machine body 1, and a dust suction device 4 provided on the outside of the collecting device 3; when the grinding wheel machine body 1 is working, the dust suction device 4 and the collecting device 3 can be used to suck up the debris and dust and store them inside the collecting device 3, avoiding the need for workers to clean the debris and dust separately after processing.

[0031] The collecting device 3 includes a suction frame 30, a guide block 31 fixedly connected to the inner wall of the suction frame 30, a collecting frame 32 fixedly connected to the side of the suction frame 30 away from the grinding wheel body 1, a limiting ring 33 fixedly connected to the inner wall of the collecting frame 32, a ball bearing 34 slidably connected to the inner wall of the limiting ring 33, a slider 35 slidably connected to the outer wall of the collecting frame 32, and a spring 36 fixedly connected to the inner wall of the slider 35. The limiting ring 33 makes it difficult for the ball bearing 34 to roll out of the collecting frame 32, and at the same time, it facilitates the disassembly of the dust collection device 4.

[0032] The vacuuming device 4 includes a mounting frame 40, with a limiting groove 41 fitted on the outer wall of the mounting frame 40. An impeller 42 is fixedly connected to the inner wall of the mounting frame 40, and a concave filter plate 43 is fixedly connected to the inner wall of the mounting frame 40. The outer wall of the mounting frame 40 is slidably connected to the outer wall of the collection frame 32, and the inner wall of the mounting frame 40 is slidably connected to the inner wall of the collection frame 32. The outer wall of the ball bearing 34 is slidably connected to the inner wall of the limiting groove 41. The concave filter plate 43 increases the amount of debris and dust accumulation, slows down the clogging speed of the concave filter plate 43, and extends the working time of the vacuuming device 4.

[0033] The protective device 2 includes a protective cover 20. The outer wall of the protective cover 20 has a dust suction port 21. The inner wall of the protective cover 20 is slidably connected to a sliding plate 22. The outer wall of the sliding plate 22 has a positioning hole 23. The inner wall of the positioning hole 23 is slidably connected to a positioning pin 24. The outer wall of the protective cover 20 is fixedly connected to the outer wall of the suction frame 30. The outer wall of the positioning pin 24 is slidably connected to the inner wall of the protective cover 20. When the positioning pin 24 is pulled out from the inside of the positioning hole 23, the sliding plate 22 is pulled, so that the sliding plate 22 extends outward from the inside of the protective cover 20. This reduces the opening angle of the protective device 2. By adjusting the opening angle of the protective device 2, the splashing of debris to the outside can be reduced, and the collection efficiency of debris can be improved.

[0034] Working principle

[0035] When in use, pick up the grinding wheel body 1 and start it to make the grinding wheel rotate to grind the workpiece. Then start the dust collection device 4. At this time, due to the high speed of the grinding wheel, the dust and debris generated by grinding the workpiece will be thrown towards the inner wall of the protective device 2 and sucked into the collection device 3 by the dust collection device 4 through the collection device 3 to collect the debris and dust generated by grinding.

[0036] First, pull the positioning pin 24 out of the positioning hole 23. Then, pull the slide plate 22, extending it outward from inside the protective cover 20, thus reducing the opening angle of the protective device 2. When the opening angle of the protective device 2 is suitable for the grinding wheel to grind the workpiece, insert the positioning pin 24 to position the slide plate 22. Then, lift the grinding wheel machine body 1 and start it, causing the grinding wheel to rotate at high speed. At this time, start the motor at the bottom of the impeller 42, causing the impeller 42 to rotate and generate negative pressure. The dust is then sucked from the grinding wheel through the collection frame 32 and the suction frame 30. When the grinding wheel grinds the workpiece, the opening of the protective device 2 becomes smaller due to the movement of the sliding plate 22. Most of the debris and dust generated when the grinding wheel grinds the workpiece will be thrown into the protective cover 20. Some debris will splash to the outside of the protective cover 20, but when the device approaches these debris, it will still be sucked into the protective cover 20. These debris will enter the suction frame 30 through the dust suction port 21 and enter the collection frame 32 under the guidance of the guide block 31. Then, they will be blocked by the concave filter plate 43 inside the collection frame 32, thus completing the collection of debris and dust.

[0037] When it is necessary to clean the debris and dust inside the collection device 3, push the slider 35 to compress the spring 36. At this time, the slider 35 will release the limit on the ball 34. Then pull the mounting frame 40. Due to the sliding connection between the limiting groove 41 and the ball 34, when the mounting frame 40 is pulled out of the collection frame 32, the ball 34 will move away from the mounting frame 40 due to the setting of the limiting ring 33 and be blocked by the bottom of the slider 35 to prevent the ball 34 from falling out of the collection frame 32. When the mounting frame 40 is removed from the collection frame 32, the debris and dust inside the collection frame 32 and the top of the concave filter plate 43 can be cleaned.
