Description

Technical Field

[0001] The invention relates to the technical field of automatic grinding, and in particular to a precision composite grinding machine. Background Art

[0002] A compound grinder is a machine tool that combines multiple grinding processing methods. It can perform multiple processing operations at the same time, such as external cylindrical grinding, internal cylindrical grinding, surface grinding, turning, milling and drilling, etc. This versatility enables the compound grinder to adapt to a variety of processing needs, reduce the type and quantity of equipment, and reduce production costs.

[0021] Specifically, a group of blowing components 4 are installed inside the device body 1, and the interior of the blowing component 4 includes an airbag 41, a spring 42, an air inlet 43, an air outlet box 44, an extrusion plate 45 and a support block 46. The support block 46 is fixedly installed on the device body 1, and multiple groups of airbags 41 are fixedly installed on the upper end of the support block 46.

[0023] (1) In the present invention, after a workpiece is polished, the rangefinder 14 starts to detect the distance between the protective shell 12 and the grinding wheel 13. After the detection is completed, it transmits the data to the central control system (not shown). After the central control system receives the data, it controls the second motor 22 to start. At this time, the second motor 22 drives the cable drum 23 to rotate, and the cable drum 23 gradually reels the steel rope 24. The connecting column 33 drives the baffle 31 to rotate, shortening the distance between the connecting plate 32 and the cable drum 23. The shortened distance is the increased distance between the protective shell 12 and the grinding wheel 13 after they are worn. The distance between the baffle 31 and the grinding wheel 13 is always controlled at a constant value to prevent the gap between the baffle 31 and the grinding wheel 13 from gradually increasing due to the wear of the grinding wheel 13, causing sparks to splash out through the debris. During the grinding process of the grinding wheel 13, water at the water source will enter the water tank 34 through the pipe 39 and the hose 320, and then flow out through the gap opened at the bottom of the water tank 34, and flow down along the inner wall of the baffle 31, thereby wetting the side wall of the baffle 31. When the spark debris contacts the inner wall of the baffle 31, it will be extinguished instantly and no longer have adhesion. Finally, it will follow the water flow and enter the interlayer between the fixed box 36 and the baffle 31. The water flow will enter the interior of the fixed box 36 through the sieve holes on the baffle plate 38, and then be transported to the nozzle 37 by the pump inside the fixed box 36, and then sprayed on the grinding wheel 13 to cool down the grinding wheel 13, while the metal debris will be blocked by the baffle plate 38 in the interlayer formed by the baffle plate 38 and the baffle 31, so that the metal debris can be collected, which is convenient for subsequent cleaning and reuse, effectively saving resources.

[0024] (2) The present invention first places the workpiece to be polished on the workbench, fixes it with a clamping mechanism (not shown), and then starts the first motor 51. At this time, the first motor 51 drives the transmission shaft 52 to rotate, and the transmission chain 53 coupled to the transmission shaft 52 drives the connecting shaft 55 to rotate together, and the connecting shaft 55 drives the grinding wheel 13 to rotate, thereby polishing the workpiece.

[0025] (3) In the present invention, during the rotation of the transmission shaft 52, the extrusion plate 45 is driven to move together. During the movement, the extrusion plate 45 continuously squeezes the arc surface of the air inlet 43. The air inlet 43 is squeezed, and the gas inside it is blown toward the outer wall of the grinding wheel 13 through the air outlet box 44. While cooling, the water droplets adhering to the outer wall of the grinding wheel 13 are dried to prevent the water droplets from forming a water film on the surface of the grinding wheel, resulting in the inability to directly contact the grinding wheel 13 and affect the grinding quality. When the extrusion plate 45 no longer squeezes the airbag 41, the spring 42 inside the airbag 41 drives the airbag 41 to return to its original state, and the external air also enters the airbag 41 through the air inlet 43 to replenish the missing gas inside the airbag 41.

[0026] Working principle: first, place the workpiece to be polished on the workbench, fix it with a clamping mechanism (not shown), and then start the first motor 51. At this time, the first motor 51 will drive the transmission shaft 52 to rotate, and the transmission chain 53 coupled to the transmission shaft 52 will drive the connecting shaft 55 to rotate together, and the connecting shaft 55 will drive the grinding wheel 13 to rotate, so as to polish the workpiece. After polishing a workpiece, the rangefinder 14 will start to detect the distance between the protective shell 12 and the grinding wheel 13. After the detection is completed, it will transmit the data to the central control system (not shown). After the central control system receives the data, it will control the second motor 22 to start. At this time, the second motor 22 will The cable drum 23 is driven to rotate, and the cable drum 23 will gradually reel in the steel rope 24, and the connecting column 33 will drive the baffle plate 31 to rotate, while shortening the distance between the connecting plate 32 and the cable drum 23. The shortened distance is the increased distance between the protective shell 12 and the grinding wheel 13 after they are worn. The spacing between the baffle plate 31 and the grinding wheel 13 is always controlled at a constant value to prevent the gap between the baffle plate 31 and the grinding wheel 13 from gradually increasing due to the wear of the grinding wheel 13, causing sparks and debris to splash out through the debris. During the grinding work of the grinding wheel 13, water at the water source will enter the interior of the water tank 34 through the pipe 39 and the hose 320, and then enter the water tank 34 through the bottom opening of the water tank 34 The spark fragments will flow out through the gap designed and flow down along the inner wall of the baffle 31, thereby wetting the side wall of the baffle 31. When the spark fragments come into contact with the inner wall of the baffle 31, they will be extinguished instantly and no longer have adhesion. Finally, they will follow the water flow and enter the interlayer between the fixed box 36 and the baffle 31. The water flow will enter the interior of the fixed box 36 through the sieve holes on the baffle plate 38, and then be transported to the nozzle 37 by the pump inside the fixed box 36, and then sprayed on the grinding wheel 13 to cool the grinding wheel 13. The metal fragments will be blocked by the baffle plate 38 in the interlayer composed of the baffle plate 38 and the baffle 31, so that the metal fragments can be collected, which is convenient for subsequent cleaning and reuse, effectively saving resources, and when the transmission shaft 52 rotates During the process, the squeezing plate 45 will be driven to move together. The squeezing plate 45 will continuously squeeze the arc surface of the air inlet 43 during the movement. The air inlet 43 is squeezed, and the gas inside it will be blown to the outer wall of the grinding wheel 13 through the air outlet box 44. While cooling, the water droplets adhering to the outer wall of the grinding wheel 13 will be dried to prevent the water droplets from forming a water film on the surface of the grinding wheel, resulting in the inability to directly contact the grinding wheel 13 and the workpiece, affecting the grinding quality. When the squeezing plate 45 no longer squeezes the airbag 41, the spring 42 inside the airbag 41 will drive the airbag 41 to return to its original state, and the external air will also enter the airbag 41 through the air inlet 43 to replenish the missing gas inside the airbag 41.
