Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding wheel technology, specifically to a grinding wheel with a noise reduction structure. Background Technology
[0002] A grinding wheel machine is an electric tool that uses a high-speed rotating grinding wheel to grind, cut, remove rust, or polish materials such as metal and stone. It is widely used in industrial fields such as machining, mold manufacturing, and automobile repair, as well as in hardware processing scenarios. It mainly consists of a base, a motor, a grinding wheel, and a protective cover. During operation, the motor drives the grinding wheel to rotate at high speed, and the grinding is achieved by the friction between the abrasive grains on the surface of the grinding wheel and the workpiece.
[0003] In current grinding machines, the high-speed rotating grinding wheel rubs against the workpiece, and the severe vibrations and impacts generated during cutting cause high-frequency air vibrations, resulting in noise. At the same time, the internal electromagnetic force of the motor and the friction of the rotating bearings also exacerbate the noise generation, thus disrupting the quiet working environment and affecting the work efficiency and physical and mental health of other personnel. To address this, we propose a grinding machine with a noise reduction structure. Utility Model Content
[0004] The purpose of this utility model is to provide a grinding wheel machine with a noise reduction structure, which can reduce the noise of the grinding wheel machine during operation, avoid the noise from disrupting the quiet working environment, and prevent it from affecting the work efficiency and physical and mental health of other personnel. It solves the problem that in the current use of grinding wheel machines, the high-speed rotating grinding wheel rubs against the workpiece and the severe vibration and impact generated during cutting will cause high-frequency vibration of the air to form noise. At the same time, the internal electromagnetic force of the motor and the friction of the bearing rotation will also aggravate the noise generation, thereby disrupting the quiet working environment and affecting the work efficiency and physical and mental health of other personnel.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding wheel machine with a noise reduction structure, comprising a base and a soundproof cover. The soundproof cover and the grinding wheel machine body are fixedly installed on the upper surface of the base, and the grinding wheel machine body is located inside the soundproof cover. An opening is provided on the front surface of the soundproof cover, and a rotating soundproof plate is rotatably installed inside the opening via a hinge. A through-hole is provided on one side of the front surface of the rotating soundproof plate, and a transparent soundproof plate is provided on the rear surface of the rotating soundproof plate at the through-hole. A helical spring is fixedly connected to all four sides of the outer surface of the transparent soundproof plate, and the end of the helical spring is fixedly connected to the rear surface of the rotating soundproof plate. An operation window is provided on the front surface of the transparent soundproof plate, and soundproofing films are fixedly installed on the top and bottom of the inner wall of the operation window.
[0006] Preferably, the soundproof cover and the base are fixedly connected by bolts.
[0007] Preferably, the upper surface of the base is provided with a limiting slot, and the bottom of the soundproof cover is located inside the limiting slot.
[0008] Preferably, a control switch is fixedly installed on the upper surface of the base, and the control switch is located inside the soundproof cover. The control switch is electrically connected to the grinding wheel body.
[0009] Preferably, a fixing ring is fixedly installed on the front surface of the rotating sound insulation plate and the sound insulation cover near the lower surface, and a pin is movably inserted into the fixing ring.
[0010] Preferably, a limit block is fixedly installed on the front surface of the pin at a position above the two fixing rings.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model, by setting up a base, a grinding wheel body, a soundproof cover, a rotating soundproof plate, an opening, a through-hole, a transparent soundproof plate, a helical spring, an operating window, and soundproof film, achieves the effect of noise reduction for the grinding wheel during operation, preventing noise from disrupting the quiet working environment and affecting the work efficiency and physical and mental health of other personnel. After rotating and opening the rotating soundproof plate, the workpiece is placed inside the soundproof cover through the opening. Then, rotating and closing the rotating soundproof plate allows the worker to pass their hands through the operating window and hold the workpiece to perform grinding and other processing through the grinding wheel body. Because the grinding wheel body is enclosed in the space composed of the base, soundproof cover, rotating soundproof plate, soundproof film, and transparent soundproof plate, the noise generated by the grinding wheel body during operation cannot be transmitted to the outside, thus achieving the effect of noise reduction.
[0013] 2. This utility model achieves the effect of facilitating the disassembly and assembly of the soundproof cover and the maintenance of the grinding wheel body inside the soundproof cover by setting bolts and limiting slots. The soundproof cover can be disassembled by removing the bolts to facilitate the maintenance of the grinding wheel body inside the soundproof cover. When installing the soundproof cover, its bottom is inserted into the limiting slot, which plays a limiting role in the soundproof cover and improves the stability of the soundproof cover after installation.
[0014] 3. This utility model achieves the effect of facilitating the rotation and closing of the sound insulation panel by setting a fixing ring, a pin, and a limiting block. When the sound insulation panel rotates into the opening, the sliding pin is inserted into the two fixing rings, thereby fixing the rotating sound insulation panel after it is closed. The limiting block limits the pin and prevents the pin from slipping out of the fixing ring. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] Example 1
[0022] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model proposes a grinding wheel machine with a noise reduction structure, including a base 1 and a soundproof cover 3. The soundproof cover 3 and the grinding wheel machine body 15 are fixedly installed on the upper surface of the base 1, and the grinding wheel machine body 15 is located inside the soundproof cover 3. The grinding wheel machine body 15 consists of a motor, a grinding wheel, and a protective cover. The motor drives the grinding wheel to rotate, and the grinding wheel is located inside the protective cover. The grinding wheel grinds the workpiece. The soundproof cover 3 includes a cover body made of soundproofing material and sound-absorbing material on the inner wall of the cover. An opening 5 is provided on the front surface of the soundproof cover 3, and a rotating soundproof plate 6 is rotatably installed inside the opening 5 via a hinge 4. The hinge 4 is located above the rotating soundproof plate 6. A through-hole 7 is provided on one side of the front surface. The through-hole 7 is located near the grinding wheel. A transparent sound insulation plate 8 is provided on the rear surface of the rotating sound insulation plate 6 at the position of the through-hole 7. A spiral spring 9 is fixedly connected to all four sides of the outer surface of the transparent sound insulation plate 8, and the end of the spiral spring 9 is fixedly connected to the rear surface of the rotating sound insulation plate 6. An operation window 10 is provided on the front surface of the transparent sound insulation plate 8. Sound insulation films 11 are fixedly installed on the top and bottom of the inner wall of the operation window 10. A control switch 16 is fixedly installed on the upper surface of the base 1, and the control switch 16 is located inside the sound insulation cover 3. The control switch 16 is electrically connected to the grinding wheel body 15, and the start and stop of the grinding wheel body 15 are controlled by the control switch 16.
[0023] In use, after rotating and opening the rotating soundproof plate 6, the workpiece is placed inside the soundproof cover 3 through the opening 5. Then, rotating and closing the rotating soundproof plate 6 allows the worker to pass their hands through the operating window 10 and hold the workpiece for grinding and other processing through the grinding machine body 15. Since the grinding machine body 15 is enclosed in the space composed of the base 1, the soundproof cover 3, the rotating soundproof plate 6, the soundproof film 11, and the transparent soundproof plate 8, the noise generated by the grinding machine body 15 during operation cannot be transmitted to the outside, thus achieving noise reduction and preventing noise from disrupting the quiet working atmosphere and affecting the work efficiency and physical and mental health of other personnel.
[0024] Example 2
[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the present invention proposes a grinding wheel machine with a noise reduction structure. Compared with the first embodiment, this embodiment further includes a soundproof cover 3 and a base 1 fixedly connected by bolts 2. The upper surface of the base 1 is provided with a limit slot 17, and the bottom of the soundproof cover 3 is located inside the limit slot 17. The rotating soundproof plate 6 and the front surface of the soundproof cover 3 near the lower surface are both fixedly installed with fixing rings 13, and pins 12 are movably inserted inside the fixing rings 13. Limit blocks 14 are fixedly installed on the front surface of the pins 12 above the two fixing rings 13. When the rotating soundproof plate 6 rotates into the opening 5, the sliding pins 12 are inserted into the two fixing rings 13, thereby fixing the rotating soundproof plate 6 after rotation is closed. The limit blocks 14 limit the pins 12 and prevent the pins 12 from slipping out of the fixing rings 13.
[0026] In this embodiment, the soundproof cover 3 can be removed by unscrewing bolt 2, so that the grinding wheel body 15 inside the soundproof cover 3 can be inspected. When installing the soundproof cover 3, its bottom is inserted into the limiting slot 17, which plays a limiting role for the soundproof cover 3 and improves the stability of the soundproof cover 3 after installation.
[0027] The above specific embodiments are merely several preferred embodiments of this utility model.
