Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and more specifically, to a cutting grinding wheel. Background Technology

[0002] As a common tool in the field of machining, cutting grinding wheels are widely used in the cutting and grinding of metal and non-metal materials. Their performance directly affects the processing efficiency and accuracy. However, the chips generated by traditional cutting grinding wheels during the cutting process tend to adhere to the surface of the grinding wheel, which not only affects the sharpness of the cutting edge, but may also cause the dynamic balance of the grinding wheel to become unbalanced, requiring frequent machine stops for cleaning and reducing production efficiency.

[0003] The utility model patent with announcement number CN222874222U discloses a grinding wheel with a cooling mechanism, including a grinding wheel body. A rotating shaft is fixedly connected to one side of the grinding wheel body. A cooling device is provided on the outer surface of the grinding wheel body. In order to prevent the grinding wheel from getting too hot during operation, an external water pipe injects water into the water inlet pipe. This allows the water inside the water inlet pipe to contact the two sides of the grinding wheel body and cool the grinding wheel body. At the same time, a limiting rod is embedded in the limiting hole. This causes the limiting member to rotate when the grinding wheel body rotates, allowing the moving part to rotate inside the rotating groove.

[0004] Although this invention makes the grinding wheel body more stable when rotating, and when water comes into contact with the guide, the water will be sprayed onto the outer surface of the grinding wheel body by the inclined surface set at the bottom of the guide, which allows the grinding wheel body to cool down quickly, the debris generated during the use of the grinding wheel is easy to adhere to the surface of the grinding wheel, which will affect the operation of the grinding wheel. Utility Model Content

[0005] The purpose of this invention is to provide a cutting grinding wheel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cutting grinding wheel includes a base plate, a mounting base fixed to the top surface of the base plate, a protective cover fixed to the top of the mounting base, a motor fixed inside the top of the mounting base, an output shaft of the motor extending into the protective cover and coaxially connected to a drive shaft, and a cutting grinding wheel fixed to the middle of the drive shaft. The wheel also includes:

[0008] Two cleaning mechanisms are installed inside the protective cover. The two cleaning mechanisms are located on the front and rear sides of the cutting grinding wheel, respectively. Each cleaning mechanism includes a mounting frame, which is fixed to the inner surface of the protective cover. A cleaning brush is slidably connected inside the mounting frame, and several bristles are regularly attached to the side of the cleaning brush near the cutting grinding wheel.

[0009] A vacuuming mechanism, the vacuuming mechanism including a vacuuming pipe fixed to the bottom end of the protective cover;

[0010] The cooling mechanism includes a collection box fixed to the top of the protective cover, and a plurality of nozzles extending into the protective cover are regularly installed at the bottom of the collection box.

[0011] Preferably, the mounting frame is U-shaped, and the upper and lower horizontal plates of the mounting frame are provided with sliding grooves on their opposite sides. The top and bottom surfaces of the cleaning brush are fixed with sliders that correspond to the positions of the sliding grooves and are adapted to the size.

[0012] Preferably, the cleaning mechanism further includes a driven shaft, which is rotatably connected inside the protective cover near the drive shaft;

[0013] Preferably, the cleaning brush has a control groove on the side near the driven shaft, a turntable is fixed to the other end of the driven shaft, and a control post that cooperates with the control groove is fixed near the edge of the turntable;

[0014] Preferably, a drive gear is fixed to both the front and rear ends of the outer wall of the drive shaft, and a driven gear is fixed to the outer wall of the driven shaft. The drive gear meshes with the driven gear on the same side.

[0015] These four settings enable automated linkage between the cleaning mechanism and the cutting wheel by driving the driven shaft through the active shaft. No additional power source is required, simplifying the system structure and reducing energy consumption. The cleaning brush is repeatedly moved by the control column movement, avoiding cleaning only a single location and improving cleaning uniformity.

[0016] Preferably, the dust collection mechanism further includes a collection box fixed to the top surface of the substrate, and the air outlet of the dust collection pipe is installed at the bottom of the collection box.

[0017] Preferably, a filter plate is slidably inserted into the middle of the collection box, and an exhaust fan is fixed to the top of the collection box;

[0018] These two features collect wastewater, dust, and debris through collection boxes, preventing them from re-attaching to the grinding wheel or drifting into the working environment, thus improving the overall cleaning performance of the equipment.

[0019] Preferably, the cooling mechanism further includes a water pump and a water tank, with the water pump inlet connected to the water tank and the water pump outlet connected to the collection box via a water supply pipe.

[0020] This feature uses a water pump to draw coolant from the drive tank and spray it evenly onto the surface of the cutting wheel through nozzles, creating a continuous cooling effect to prevent the cutting wheel from experiencing performance degradation due to high temperatures. At the same time, the coolant can help flush away debris and improve cleaning efficiency.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This utility model, through the design of the cleaning mechanism, drives the cleaning brush to slide back and forth along the groove of the mounting frame via the turntable and control column at the end of the driven shaft, thereby achieving automatic removal of debris from the surface of the cutting grinding wheel without manual intervention and improving the continuity of processing.

[0039] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0040] Please see Figures 1-6 The present invention provides the following technical solution:

[0041] A cutting grinding wheel includes a base plate 100, a mounting base 200 fixed to the top surface of the base plate 100, a protective cover 400 fixed to the top of the mounting base 200, a motor 300 fixed inside the top of the mounting base 200, an output shaft of the motor 300 extending into the protective cover 400 and coaxially connected to a drive shaft 500, and a cutting grinding wheel 600 fixed in the middle of the drive shaft 500. The wheel also includes:

[0042] Two cleaning mechanisms 700 are used to clean dust and debris from the cutting grinding wheel 600. The two cleaning mechanisms 700 are installed inside the protective cover 400 and are located on the front and rear sides of the cutting grinding wheel 600, respectively. Each cleaning mechanism 700 includes a mounting frame 701, which is fixed to the inner surface of the protective cover 400. A cleaning brush 702 is slidably connected inside the mounting frame 701. Several bristles 7020 are regularly attached to the side of the cleaning brush 702 closest to the cutting grinding wheel 600. The bristles 7020 of the cleaning brush 702 continuously clean the debris from the surface of the cutting grinding wheel 600, preventing debris from adhering and affecting the sharpness and dynamic balance of the cutting edge, reducing the frequency of downtime for cleaning, and improving processing efficiency.

[0043] A vacuuming mechanism 800 for collecting wastewater, dust and debris includes a vacuum pipe 801 fixed to the bottom of a protective cover 400. The vacuum pipe 801 collects the debris and dust that have been cleaned up, and works with a subsequent collection box 802 to achieve centralized waste disposal, keep the working environment clean and reduce dust pollution.

[0044] A cooling mechanism 900 is used to reduce the working temperature of the cutting grinding wheel 600. The cooling mechanism 900 includes a collection box 901 fixed to the top of the protective cover 400. Several nozzles 902 extending into the protective cover 400 are regularly installed at the bottom of the collection box 901 to reduce the heat generated during grinding, prevent the grinding wheel from overheating and wearing, extend its service life and improve the machining accuracy.

[0045] In this embodiment, please refer to Figures 1-4The mounting bracket 701 is U-shaped. The upper and lower horizontal plates of the mounting bracket 701 are provided with sliding grooves 7010 on opposite sides. The top and bottom surfaces of the cleaning brush 702 are fixed with sliders 7021 that correspond to the position of the sliding grooves 7010 and are adapted in size. The sliding grooves 7010 ensure that the cleaning brush 702 maintains its contact with the surface of the cutting wheel 600 during reciprocating motion, thereby improving the cleaning effect.

[0046] Specifically, the cleaning mechanism 700 also includes a driven shaft 704, which is rotatably connected inside the protective cover 400 near the drive shaft 500. The driven shaft 704 serves as a power transmission intermediary and can be driven by the drive shaft 500 to achieve automated rotation, providing a power source for the reciprocating motion of the cleaning brush 702 without the need for an additional power unit, simplifying the structure and reducing energy consumption.

[0047] Furthermore, a control groove 7022 is provided on the side of the cleaning brush 702 near the driven shaft 704, and a turntable 706 is fixed at the other end of the driven shaft 704. A control column 707 that cooperates with the control groove 7022 is fixed near the edge of the turntable 706. The rotation of the turntable 706 drives the control column 707 to move, thereby making the cleaning brush 702 move repeatedly, avoiding cleaning only a single position and improving cleaning uniformity and efficiency.

[0048] In addition, a drive gear 703 is fixed at both the front and rear ends of the outer wall of the drive shaft 500, and a driven gear 705 is fixed at the outer wall of the driven shaft 704. The drive gear 703 and the driven gear 705 on the same side mesh with each other. Through the meshing transmission of the drive gear 703 and the driven gear 705, the rotational power of the drive shaft 500 is synchronously transmitted to the driven shaft 704, so that the cleaning mechanism 700 and the cutting grinding wheel 600 work together in linkage. Without manual intervention, automated continuous cleaning is achieved, further improving processing efficiency.

[0049] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 The vacuuming mechanism 800 also includes a collection box 802 fixed to the top surface of the base plate 100. The air outlet of the vacuum pipe 801 is installed at the bottom of the collection box 802. The collection box 802 provides a centralized storage space for debris and dust. With the airflow guidance of the vacuum pipe 801, it can achieve efficient collection of waste, avoid scattered pollution, and facilitate subsequent unified cleaning.

[0050] Specifically, a filter plate 803 is slidably inserted into the middle of the collection box 802, an exhaust fan 804 is fixed at the top of the collection box 802, and a door is hinged at the front of the collection box 802. The door also needs to be equipped with appropriate waterproofing measures. The filter plate 803 can separate solid particles in the airflow, purify the exhaust air, reduce dust emissions, and meet environmental protection requirements. At the same time, the sliding filter plate 803 is easy to disassemble and clean.

[0051] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 6 The cooling mechanism 900 also includes a water pump 904 and a water tank 905. The inlet of the water pump 904 is connected to the water tank 905, and the outlet of the water pump 904 is connected to the collection box 901 through a water supply pipe 903. The cover can be opened to add coolant. The coolant can reduce the temperature and also assist in cleaning, improving cleaning efficiency.

[0052] Finally, it should be noted that the components involved in this utility model, such as the motor 300, the exhaust fan 804, and the water pump 904, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0053] When the cutting grinding wheel of this utility model is in use, the motor 300 is started, and its output shaft drives the drive shaft 500 to rotate, thereby driving the cutting grinding wheel 600 to rotate at high speed to perform cutting or grinding operations on the workpiece.

[0054] The drive gears 703 at both ends of the drive shaft 500 rotate with the shaft, and drive the driven gear 705 and the driven shaft 704 to rotate through meshing transmission. The turntable 706 at the end of the driven shaft 704 rotates synchronously. The control post 707 at the edge is embedded in the control groove 7022 of the cleaning brush 702, driving the cleaning brush to slide back and forth along the slide groove 7010 of the mounting bracket 701. The bristles 7020 on the cleaning brush 702 continuously contact the surface of the cutting wheel 600 to remove the attached debris and avoid affecting the sharpness of the cutting edge and dynamic balance.

[0055] When the water pump 904 is started, the coolant in the water tank 905 is pumped into the collection box 901 through the water pipe 903, and then evenly sprayed onto the surface of the cutting wheel 600 through the bottom nozzle 902 to reduce grinding heat and help flush away debris.

[0056] When the exhaust fan 804 is running, it draws debris, coolant, and dust from the protective cover 400 into the collection box 802 through the suction pipe 801. The filter plate 803 in the collection box 802 filters solid particles, and the purified air is discharged, while the liquid and debris remain in the box.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
