TECHNICAL FIELD
[0001] The utility model relates to the technical field of surface grinder, especially to be used for the surface grinder of distribution box sheet metal. BACKGROUND
[0002] In the production and processing flow of distribution box sheet metal, the surface grinder plays a crucial role. The distribution box sheet metal has strict requirements on flatness and surface roughness. Only with the help of the surface grinder for fine processing can the size of the distribution box be ensured to be accurate and correct, meet the installation needs of electrical components, and at the same time ensure that it has good appearance quality and meets relevant industry standards. Moreover, the efficient and stable surface grinder processing process can effectively improve the production efficiency of the distribution box sheet metal, reduce the scrap rate, thereby saving costs and improving economic benefits for the entire distribution box manufacturing industry.
[0003] In the past surface grinder technical system, the cooling system usually adopts a relatively simple structure mode. Generally, a single nozzle is used to spray water to the contact area between the grinding wheel and the workpiece to reduce the grinding temperature. After the cooling liquid is extracted from the water tank, it is directly delivered to the nozzle through the pipeline. After completing the cooling task, the cooling liquid mixed with grinding dust is discharged to the outside. In this process, the high-speed rotation of the grinding wheel and the severe friction with the sheet metal material will generate a large amount of heat. In order to maintain effective cooling effect, the traditional cooling system has to continuously and massively spray water.
[0004] Due to its simple structure, the cooling liquid is only used once and then discharged during water cooling, which cannot be recycled, resulting in a large consumption of water resources and waste of resources. Moreover, frequent replenishment of cooling liquid and disposal of discharged waste liquid increase the maintenance cost of the equipment. Therefore, the surface grinder for distribution box sheet metal is proposed to solve the above problems. UTILITY MODEL CONTENTS

Based on the embodiments in the present application, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the present application. Figure 1 Figure 3 The present application provides an embodiment: a planar grinding machine for power distribution box sheet metal, including workbench 1, the side wall of workbench 1 is fixedly connected with stand 2, the side wall of stand 2 is provided with fixed assembly, the side wall of workbench 1 is fixedly connected with electromagnetic chuck 3, the inside of workbench 1 is provided with cooling assembly;Cooling assembly includes cooling water tank 4, cooling water tank 4 is fixedly connected in the inside of workbench 1, water pump 5 is fixedly connected in the inside of workbench 1, the input end of water pump 5 is fixedly connected with connecting pipe 6, the output end of water pump 5 is fixedly connected with delivery pipe 7, delivery pipe 7 penetrates the side wall of workbench 1, the side wall of workbench 1 is fixedly connected with fixed block 8, the side wall of delivery pipe 7 is fixedly connected with spray head 9, vertical groove 10 is set in the inside of workbench 1, vertical groove 10 is used to provide passageway for water and chippings, so that it can flow into the inside of fixed pipe 11 from the surface of workbench 1, fixed pipe 11 is set in the inside of workbench 1, one end of fixed pipe 11 is fixedly connected in the side wall of vertical groove 10, the other end of fixed pipe 11 is fixedly connected in the side wall of cooling water tank 4, filter frame 23 is slidably connected in the inside of cooling water tank 4, filter frame 23 is used to intercept chippings impurities in water, connecting pipe 6 is fixedly connected in the side wall of cooling water tank 4, delivery pipe 7 is fixedly connected in the inside of fixed block 8;
[0034] Because the grinding wheel body 13 in the process of operation, its high-speed rotation and distribution box sheet workpiece friction, will quickly produce a large amount of heat. If not in time to cool down, not only will make the grinding wheel wear and tear, shorten the service life, but also may make the workpiece due to overheating and deformation, affect the machining precision and quality. At this time start the water pump 5, the water pump 5 is to provide power, through the connecting pipe 6 to extract the cooling liquid inside the cooling water tank 4. The connecting pipe 6 is responsible for the communication between the cooling water tank 4 and the water pump 5, to ensure that the cooling liquid can be extracted smoothly. The extracted cooling liquid is transported to the nozzle 9 through the delivery pipe 7. The delivery pipe 7 plays a role in transmitting the cooling liquid, ensuring that the cooling liquid can reach the nozzle 9. The nozzle 9 sprays water to the grinding wheel body 13 for cooling, and the nozzle 9 can spray the cooling liquid at a specific angle and range, uniformly covering the grinding wheel body 13 and efficiently removing heat. The water and debris falling subsequently enter the fixed pipe 11 through the vertical groove 10 opened inside the workbench 1. The vertical groove 10 provides a channel for water and debris, allowing them to flow smoothly from the surface of the workbench 1 into the fixed pipe 11. The fixed pipe 11 then transports them to the inside of the cooling water tank 4, where they are filtered by the filter frame 23 for recycling. The filter frame 23 is used to intercept the debris in the water, allowing clean cooling liquid to be recycled, saving cooling liquid resources and reducing production costs. When the filter frame 23 needs to be cleaned, it can be pulled out for cleaning, which is convenient and can timely remove the accumulated impurities in the filter frame 23, maintaining the filtering effect. After multiple cycles, the water quality decreases, and the water can be drained through the drain pipe. The drain pipe can drain the cooling liquid in the cooling water tank 4 that does not meet the quality standards, making it easy to replace the new cooling liquid and ensuring the cooling effect.
[0035] With reference to Figure 1 , Figure 3 and Figure 4 , the fixing assembly includes a connecting block 19, a connecting shaft 12 is arranged inside the electromagnetic chuck 3, the connecting shaft 12 has a sand wheel body 13 slidingly connected to the side wall, the electromagnetic chuck 3 has a sand wheel box one 14 fixedly connected to the side wall, the sand wheel box one 14 has a sand wheel box two 15 arranged on the side wall, the sand wheel body 13 is rotatably connected inside the sand wheel box one 14 and the sand wheel box two 15, the sand wheel box two 15 and the sand wheel box one 14 are used to accommodate and fix the sand wheel body 13, the sand wheel box two 15 has a positioning pin 16 fixedly connected to the side wall, the sand wheel box one 14 has a positioning hole 17 opened inside, the positioning pin 16 is slidingly connected inside the positioning hole 17, the sand wheel box one 14 has a fixing frame 18 fixedly connected to the side wall, the connecting block 19 is fixedly connected to the side wall of the sand wheel box two 15, the connecting block 19 has a clamping block 20 slidingly connected inside, the connecting block 19 and the clamping block 20 are slidingly connected inside the fixing frame 18, the clamping block 20 has a limiting block 21 fixedly connected to the side wall, the limiting blocks 21 are fixedly connected with a spring 22 therebetween, and the spring 22 is used for elastic return;
[0036] When the grinding wheel body 13 needs to be replaced, the grinding wheel box two 15 is pulled to move. The grinding wheel box two 15 is used for containing and fixing the grinding wheel body 13, and protecting the grinding wheel body 13 from being damaged during operation and replacement. The movement of the grinding wheel box two 15 causes the clamping block 20 to be pressed by the fixing frame 18. The clamping block 20 and the fixing frame 18 cooperate, and in the normal state, the clamping block 20 and the fixing frame 18 play a role in fixing the grinding wheel box two 15, preventing it from moving accidentally. The clamping block 20 enters the inside of the connecting block 19 to press the spring 22. The spring 22 stores elastic potential energy when being pressed, and can reset the clamping block 20 when the clamping block 20 is not pressed. With the movement of the clamping block 20, the fixing of the grinding wheel box two 15 is cancelled, and at the same time, the movement of the grinding wheel box two 15 causes the positioning pin 16 to be separated from the inside of the positioning hole 17. The positioning pin 16 and the positioning hole 17 cooperate, and play a role in positioning the grinding wheel box two 15 and the grinding wheel box one 14. After the positioning is cancelled, the grinding wheel box two 15 is taken down to facilitate the replacement of the grinding wheel body 13 inside.
[0037] Working principle: Since the grinding wheel body 13 generates heat during operation, the water pump 5 is started to pump the cooling liquid in the cooling water tank 4 out through the connecting pipe 6, and then the cooling liquid is transported to the spray head 9 through the conveying pipe 7. The spray head 9 sprays water flow to the grinding wheel body 13 for cooling. Then the falling water and debris enter the fixed pipe 11 through the vertical groove 10 opened in the workbench 1, and then are transported to the inside of the cooling water tank 4 through the fixed pipe 11. The cooling liquid is recycled by being filtered through the filter frame 23. When the filter frame 23 needs to be cleaned, it is pulled out to be cleaned. After multiple cycles, the water quality decreases, and the water can be drained through the drain pipe.
[0038] When the grinding wheel body 13 needs to be replaced, the grinding wheel box two 15 is pulled to move. The movement of the grinding wheel box two 15 causes the clamping block 20 to be pressed by the fixing frame 18, and the clamping block 20 enters the inside of the connecting block 19 to press the spring 22. With the movement of the clamping block 20, the fixing of the grinding wheel box two 15 is cancelled, and at the same time, the movement of the grinding wheel box two 15 causes the positioning pin 16 to be separated from the inside of the positioning hole 17, and the positioning is cancelled. Then the grinding wheel box two 15 is taken down to facilitate the replacement of the grinding wheel body 13 inside.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
