Description

Technical Field

[0002] Flanges are usually used for the connection of pipeline systems or mechanical components. They are disc-shaped connecting parts. The structure of a flange usually has bolt holes on the outer periphery and a hole through which a pipeline or equipment passes in the middle.

[0003] During the processing of flanges, it is necessary to grind and polish their surfaces to remove burrs and rough surfaces on the processed surfaces of the flanges. Usually, a grinding and polishing device is used for processing.

Detailed Description of the Preferred Embodiment

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Such as Figures 1 to 3As shown in the figure, a grinding and polishing device for flange processing according to an embodiment of the present utility model includes a workbench 1; an adjusting frame 10 is installed on one side of the top of the workbench 1; a polishing machine 11 is installed at the end of the adjusting frame 10; a rotating groove 12 is provided in the middle of the workbench 1; a motor 13 is installed in the middle of the rotating groove 12; the motor 13 is installed at the bottom of the workbench 1; the output end of the motor 13 is fixedly connected with a rotating plate 14; the rotating plate 14 is rotatably connected in the middle of the rotating groove 12; the top of the rotating plate 14 is fixedly connected with a placing plate 15; a fixing groove 16 is provided in the middle of the placing plate 15; a bidirectional lead screw 17 is rotatably connected in the middle of the fixing groove 16; one end of the bidirectional lead screw 17 penetrates through the middle of the placing plate 15; an adjusting handle 18 is fixedly connected to the end of the bidirectional lead screw 17; two nuts 19 are installed in the middle of the bidirectional lead screw 17; a fixing plate 100 is fixedly connected to the middle of the nut 19; a clamping plate 111 is installed in the middle of the fixing plate 100; the clamping plate 111 is arranged in an arc shape and is elastic; a buffer assembly 2 is provided between the middle of the fixing plate 100 and the clamping plate 111; during work, the flange to be ground is placed on the placing plate 15. At this time, the two clamping plates 111 are at the center position of the flange. Rotate the adjusting handle 18 to drive the bidirectional lead screw 17 to rotate inside the fixing groove 16. When the bidirectional lead screw 17 rotates, the two nuts 19 move to both sides, contact the inner side wall of the flange through the clamping plate 111, and absorb the stress generated when the clamping plate 111 contacts the surface of the flange through the buffer assembly 2. Continuously move to make the two clamping plates 111 support and fix the middle of the flange. Turn on the polishing machine 11, move the polishing head towards the flange and rotate at a high speed to polish the surface of the flange. The adjusting frame 10 is moved in the middle of the workbench 1 according to the set route by the control system to comprehensively grind flanges of different sizes. At the same time, the output end of the motor 13 drives the rotating plate 14 to slowly rotate in the middle of the workbench 1, so that the polishing head contacts the surface of the flange evenly. Through the above structure, the flange can be fixed during the polishing process, effectively reducing the displacement or rotation of the flange during the grinding and polishing process, effectively improving the processing accuracy of the flange, enabling the flange to remain in the center position, increasing the consistency of the grinding and polishing work of each flange, and being able to quickly adjust the moving distance and clamping force of the clamping plate 111, fixing flanges of different sizes, and reducing the quality problems of uneven surface roughness and scratches caused by vibration during the grinding and polishing process of the flange.

[0024] As Figure 2 and Figure 3As shown in the figure, the buffer assembly 2 includes two support rods 21; the two support rods 21 are hinged to the side wall of the fixed plate 100; the two support rods 21 are arranged oppositely; the clamping plate 111 is fixedly connected to the ends of the two support rods 21; a buffer spring 22 is fixedly connected to the middle of the clamping plate 111; the end of the buffer spring 22 is fixedly connected to the middle of the fixed plate 100; a buffer pad 23 is fixedly connected to the outer side wall of the clamping plate 111; during operation, when the workbench 1 continuously moves towards the middle of the flange, the buffer pad 23 in the clamping plate 111 is in flexible contact with the inner side of the flange. As the fixed plate 100 continues to move, the middle of the flange exerts a pressure on the clamping plate 111. The stressed clamping plate 111 moves towards the fixed plate 100. At this time, the two support rods 21 rotate on the side wall of the fixed plate 100, and the buffer spring 22 undergoes elastic contraction, thereby fastening the flange. The acting force of the clamping plate 111 pressing towards the middle of the flange is absorbed by the buffer spring 22 and the buffer pad 23. Through the above structure, vibration energy can be effectively absorbed and dispersed during the clamping process, the clamping force can be evenly distributed on the surface of the flange, damage caused by excessive local stress can be reduced, and the clamping plate 111 can clamp the flange more stably, thereby improving the processing accuracy of flange grinding and polishing.

[0025] As Figure 1 and Figure 4 shown in the figure, a connecting frame 3 is fixedly connected to the side wall of the adjusting frame 10; a baffle 31 is fixedly connected to the end of the connecting frame 3; the baffle 31 is arc-shaped; multiple groups of cleaning brushes 32 are fixedly connected to the middle of the baffle 31; a collecting assembly 4 is installed in the middle of the baffle 31; during operation, when the flange is fixed in the middle of the placing plate 15, the side wall of the flange is in contact with multiple groups of cleaning brushes 32. When the flange contacts the cleaning brushes 32, the cleaning brushes 32 bend due to flexibility. During the process of polishing the surface of the flange, the metal chips discharged from the polishing head and the outer side of the flange are cleaned by the cleaning brushes 32. At the same time, part of the polishing debris is blocked from splashing by the baffle 31. Through the above structure, the debris discharged towards the side wall during the flange grinding and polishing process can be effectively cleaned, and the accelerated wear caused by debris accumulation between the flange and the polishing head can be effectively reduced as the placing plate 15 rotates.

[0026] As Figure 1 and Figure 4As shown, the collection component 4 includes a dust suction device 44; the dust suction device 44 is installed on the side wall of the adjustment frame 10; the dust suction device 44 is arranged on the side away from the connecting frame 3; a dust suction pipe 41 is fixedly connected to the middle of the dust suction device 44; a cavity 42 is formed in the middle of the baffle 31; the end of the dust suction pipe 41 is fixedly connected to the bottom of the baffle 31; the end of the dust suction pipe 41 is arranged inside the cavity 42; a plurality of dust suction holes 43 are formed in the side wall of the baffle 31; the dust suction holes 43 are arranged on the side close to the cleaning brush 32; during operation, when the flange is polished, the dust suction device 44 is turned on, and through the negative pressure air flow inside the dust suction device 44, the debris generated during the flange polishing process passes through the baffle 31 and enters the middle of the plurality of dust suction holes 43. After the debris enters the cavity 42, it then enters the dust suction device 44 through the dust suction pipe 41, thereby collecting the debris. Through the above structure, the polished debris after cleaning can be collected in a timely manner, the residence time of the polished debris in the working area can be reduced, and the pollution of the surrounding area by the scattered debris can be reduced.

[0027] As Figure 2 and Figure 3 As shown, two sliding grooves 5 are formed at the end of the fixed groove 16; the two sliding grooves 5 are arranged oppositely; the two sliding grooves 5 are formed in the middle of the placement plate 15; a partition plate 51 is slidably connected to the middle of the sliding groove 5; the end of the partition plate 51 is fixedly connected to the side wall of the corresponding fixing plate 100; an installation component 6 is installed on the top of the fixing plate 100; a connecting plate 52 is installed in the middle of the installation component 6; an elastic cloth 53 is fixedly connected to the middle of the two connecting plates 52; the elastic cloth 53 is installed on the side and bottom of the two connecting plates 52; during operation, the connecting plate 52 and the elastic cloth 53 are placed in the middle of the two fixing plates 100 through the installation component 6. When the fixing plate 100 moves according to the size of the middle of the flange, the elastic cloth 53 is elastically stretched along with the movement of the two connecting plates 52, and the partition plate 51 slides inside the sliding groove 5 along with the fixing plate 100 at the same time. During the flange polishing process, part of the metal debris is collected through the elastic cloth 53 and the connecting plate 52, and the debris is intercepted by the partition plate 51. Through the above structure, the debris during the flange polishing process can be effectively intercepted from entering the fixed groove 16, the metal debris can be effectively intercepted and collected, the abrasion caused by the accumulation of metal debris in the fixed groove 16 and contacting the bidirectional lead screw 17 can be reduced, and the problem of subsequent difficult cleaning caused by the accumulation of debris in the fixed groove 16 can be reduced.

[0028] As Figure 2 and Figure 3As shown, the installation component 6 includes an installation groove 61; the installation groove 61 is opened on one side of the top of the fixed plate 100; an installation block 62 is installed in the middle of the installation groove 61; the connecting plate 52 is fixedly connected to the side wall of the installation block 62; during work, when installing the connecting plate 52 and the elastic cloth 53, install the installation blocks 62 on the side walls of the two connecting plates 52 in the corresponding installation grooves 61 on the top of the fixed plate 100, and fix the two connecting plates 52 through the installation blocks 62. Through the above structure, the two connecting plates 52 and the elastic cloth 53 for collecting debris can be quickly fixed between the two fixed plates 100, and the collected metal debris can be quickly taken out for subsequent processing.

[0029] As Figures 1 to 3 shown, an anti-slip pad 7 is fixedly connected to the middle of the placing plate 15; the anti-slip pad 7 is arranged on the top of the placing plate 15; during work, place the flange on the placing plate 15, and the bottom of the flange fits with the anti-slip pad 7. The anti-slip pad 7 increases the friction between the flange and the placing plate 15. Through the above structure, the sliding of the flange in the middle of the placing plate 15 can be effectively reduced, and the wear between the flange and the placing plate 15 during the grinding process can be reduced.

[0030] During operation, place the flange to be polished on the placement plate 15. At this time, the two clamping plates 111 are at the center position of the flange. Rotate the adjustment handle 18 to drive the bidirectional lead screw 17 to rotate inside the fixed groove 16. When the bidirectional lead screw 17 rotates, the two nuts 19 move to both sides and contact the inner side wall of the flange through the clamping plates 111. The buffer assembly 2 absorbs the stress generated when the clamping plates 111 contact the flange surface. Continuously move to support and fix the middle part of the flange with the two clamping plates 111. Turn on the polishing machine 11, move the polishing head towards the flange and rotate at high speed to polish the surface of the flange. The control system moves the adjustment frame 10 in the middle of the workbench 1 according to the set route to comprehensively polish flanges of different sizes. At the same time, the output end of the motor 13 drives the rotating plate 14 to slowly rotate in the middle of the workbench 1, so that the polishing head contacts the flange surface evenly. When the workbench 1 continuously moves towards the middle of the flange, the buffer pad 23 in the clamping plate 111 contacts the inner side of the flange flexibly. As the fixed plate 100 continuously moves, the middle part of the flange exerts pressure on the clamping plate 111. The stressed clamping plate 111 moves towards the fixed plate 100. At this time, the two support rods 21 rotate on the side wall of the fixed plate 100, and the buffer spring 22 elastically contracts, thus fastening the flange. The buffer spring 22 and the buffer pad 23 absorb the acting force of the clamping plate 111 pressing towards the middle of the flange. When the flange is fixed in the middle of the placement plate 15, the side wall of the flange contacts a plurality of cleaning brushes 32. When the flange contacts the cleaning brushes 32, the cleaning brushes 32 bend due to flexibility. During the polishing process of the flange surface, the cleaning brushes 32 clean the metal debris discharged from the polishing head and the outside of the flange. At the same time, the baffle 31 blocks part of the polishing debris from splashing. When polishing and grinding the flange, turn on the dust collection device 44. Through the negative pressure air flow inside the dust collection device 44, the debris generated during the polishing process of the flange passes through the baffle 31 and enters the middle of a plurality of dust suction holes 43. After the debris enters the cavity 42, it then enters the dust collection device 44 through the dust suction pipe 41, thereby collecting the debris. Place the connecting plate 52 and the elastic cloth 53 in the middle of the two fixed plates 100 through the installation assembly 6. When the fixed plate 100 moves according to the size of the middle part of the flange, the elastic cloth 53 elastically stretches with the movement of the two connecting plates 52. The partition plate 51 slides in the chute 5 at the same time as the fixed plate 100. During the polishing and grinding process of the flange, part of the metal debris is collected through the elastic cloth 53 and the connecting plate 52, and the debris is intercepted by the partition plate 51. When installing the connecting plate 52 and the elastic cloth 53, install the installation blocks 62 on the side walls of the two connecting plates 52 in the installation grooves 61 at the top of the corresponding fixed plates 100, and install and fix the two connecting plates 52 through the installation blocks 62. Place the flange on the placement plate 15, and the bottom of the flange fits with the anti-slip pad 7. The anti-slip pad 7 increases the friction between the flange and the placement plate 15.
