Description

Technical Field

[0001] The invention relates to the technical field of carbon brush grinding, and in particular to a positioning-based carbon brush grinding device and method. Background Art

[0002] Carbon brushes, also called brushes, are widely used as sliding contacts in many electrical devices. The main materials used in carbon brushes are graphite, impregnated graphite, and metal (containing copper and silver) graphite. Carbon brushes are devices that transfer energy or signals between the fixed part and the rotating part of a motor, generator, or other rotating machinery. They are generally made of pure carbon and a coagulant. They are generally square in shape and stuck on a metal bracket. There is a spring inside to press it tightly against the shaft. When the motor rotates, the electrical energy is transmitted to the coil through the commutator. Because its main component is carbon, it is called a carbon brush and it is easy to wear. It should be regularly maintained and replaced, and carbon deposits should be cleaned.

[0003] The carbon brush needs to be surface ground during processing to make the surface smooth and the contact area between the carbon brush and the commutator should be no less than 3 / 4 of the total contact surface.

[0004] In the prior art, a carbon brush grinding and chamfering machine disclosed in publication number "CN104589177B" includes: a workbench; a conveying device installed on the workbench for automatically orienting and sorting a plurality of carbon brushes and conveying them to the processing stations in sequence, and having a linear guide rail for conveying a plurality of carbon brushes; a surface grinding device arranged on the workbench for grinding the upper end surface of the carbon brush conveyed on the linear guide rail; a chamfering device arranged on the workbench for chamfering the carbon brush whose upper end surface has been ground. The carbon brush grinding and chamfering machine of the present invention has a simple structure and is easy to use. It can automatically and quickly grind and chamfer the upper end surface of the carbon brush, has a high degree of automation, high grinding and chamfering efficiency, good processed product quality, high production efficiency, and low production cost.

[0005] However, the existing technology still has major deficiencies, such as:

[0006] In the above-mentioned device and the prior art, when the upper end face of the carbon brush is chamfered and ground, the lower end face of the carbon brush cannot be ground synchronously at the same time. The two sides of the carbon brush are respectively fitted with the rotating shaft and the metal bracket. If one side is not smooth, it will affect the contact area between the carbon brush and the rotating shaft. At the same time, the carbon brush is easy to wear. If it is polished by pressurized contact on both sides, it is easy to cause excessive wear of the carbon brush contact surface, resulting in waste of carbon brush processing.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0041] A material block unloading and screening guide structure is arranged on one side of the support platform 32 near the conveying channel 13, and the material block unloading and screening guide structure includes a curved frame 42, and the curved frame 42 is installed on one side of the support platform 32. A first stepper motor 43 is installed on the curved frame 42, and a guide inclined plate 41 is installed on the rotating end of the first stepper motor 43. A guide curved plate 4 is installed on the surface of the guide inclined plate 41. The guide curved plates 4 are arranged in two groups, and the two groups of guide curved plates 4 are symmetrically arranged.

[0042] In this embodiment, the cut carbon brush material blocks are placed on the surface of the conveyor line 31 between the adjacent lateral frames 3, and then the conveyor line 31 is driven to convey the part of the material blocks. The conveyor line 31 will convey the material blocks to the surface of the guiding inclined plate 41. The surface of the guiding inclined plate 41 is inclined. During the conveying process, the guiding curved plate 4 converges from wide to narrow, so that the conveyed carbon brush material blocks are concentratedly guided and conveyed to the conveying channel 13 area. At the same time, during the conveying process, in order to ensure the unloading rate of the material blocks, the intermittent rotation of the first stepper motor 43 can be driven to make the guiding inclined plate 41 swing slowly, so that the unloading rate of the material blocks on the guiding inclined plate 41 is accelerated, thereby ensuring the unloading rate of the material blocks.

[0043] A carbon brush block upper surface grinding and screening unit is provided in the conveying channel 13 area, and is used for screening the carbon brush blocks conveyed by the conveying unit according to the specifications and grinding the upper surface of the carbon brush blocks;

[0044] The upper surface grinding and screening unit of the carbon brush material block includes a top grinding part, which includes an annular guide rail 5, which is installed on the outer surface of the conveying channel 13, and a partition retaining ring 51 is arranged between the annular guide rail 5 and the driving roller 58, and the partition retaining ring 51 is arranged on the surface of the grinding platform 1, and a lower top plate 52 is arranged on the movable end of the surface of the annular guide rail 5, and a through groove 521 is arranged on the surface of the lower top plate 52, and a movable cylinder 53 is also arranged on the top of the lower top plate 52, and an upper top plate 54 is arranged on the movable end of the movable cylinder 53, and a grinding brush bar 55 is arranged at the bottom of the upper top plate 54, and the grinding brush bar 55 is symmetrically arranged in two groups, and each group of grinding brush bars 55 is arranged at a plurality of intervals;

[0045] The upper surface grinding and screening unit of the carbon brush block also includes a shoveling part, which includes a driving roller 58, which is installed in the central area of ​​the annular guide rail 5, and a push plate 56 is sleeved on the rotating end of the driving roller 58, and oblique shovel plates 57 are installed on both sides of the push plate 56;

[0046] In this embodiment, after the blocking block falls into the area of ​​the conveying channel 13, the annular guide rail 5 can be driven, and the rotating end of the annular guide rail 5 will drive the lower top plate 52 to rotate. When the lower top plate 52 rotates, it drives the upper top plate 54 to rotate. During the rotation of the upper top plate 54, the movable cylinder 53 on the top of the lower top plate 52 is driven to move downward. After the movable end of the movable cylinder 53 is lowered, the grinding brush strip 55 will pass through the through groove 521 and fit the carbon brush block in the area of ​​the conveying channel 13. Then, the output power of the annular guide rail 5 is accelerated, and the rotation speed of the lower top plate 52 and the upper top plate 54 is increased, so that the grinding brush strip 55 can be easily pulled out of the conveying channel 13. The brush strip 55 effectively fits and grinds the top surface of the carbon brush block. During the process of fitting and grinding the surface of the carbon brush block, in order to ensure that the bottom of the carbon brush block can also be effectively polished by the brush strip 55, the driving roller 58 can be rotated. When the rotating end of the driving roller 58 rotates, the pushing turn plate 56 can be driven to rotate. At this time, the oblique shovel plates 57 installed on both sides of the pushing turn plate 56 will shovel the carbon brush block to turn it over during the rotation process, thereby turning the carbon brush block over, ensuring that the bottom surface of the carbon brush block can also be effectively polished, thereby improving the polishing effect of the top and bottom of the carbon brush block.

[0047] A carbon brush block conveying and lateral grinding unit is provided at the bottom area of ​​the conveying channel 13, and is used to convey the screened carbon brush blocks in the conveying channel 13 sideways, and grind the surface of the carbon brush blocks at the same time;

[0048] The carbon brush block conveying lateral grinding unit includes a conveying part, which includes a conveying guide platform 7, which is installed on the upper surface of the middle platform 2, and a conveying inclined surface 71 is provided on the surface of the conveying guide platform 7. Inclined guide rails 72 are embedded on both sides of the conveying guide platform 7, and movable blocks 73 are installed on the movable ends of the inclined guide rails 72. A movable arm 74 is installed between adjacent movable blocks 73, and a push bar 75 is installed at the bottom of the movable arm 74. A fixed frame 76 is installed on one side of the bottom of the conveying guide platform 7;

[0049] The carbon brush block conveying lateral grinding unit also includes a surface grinding part, which includes a circular grinding bin 8, the surface of the circular grinding bin 8 is set as an opening, a fixed arm 83 is set on one side of the fixed frame 76, and a second stepper motor 84 is installed on the fixed arm 83. The rotating end of the second stepper motor 84 is fixed to one side of the circular grinding bin 8, and an electric drive roller 81 is installed in the inner cavity of the circular grinding bin 8. A grinding blade 82 is sleeved on the rotating end of the electric drive roller 81. The inner cavity of the circular grinding bin 8 is provided with a medium, and a screen box 85 is set at the bottom of the circular grinding bin 8. The screen box 85 is installed on the surface of the central platform 2;

[0050] In this embodiment, the moving ends of the inclined guide rails 72 embedded on both sides of the conveying guide platform 7 will drive the moving arms 74 to move back and forth. During the movement of the moving arms 74, the pushing bars 75 will be driven to push the carbon brush material blocks to be discharged. At the same time, the dust generated during the grinding process will be swept up during the pushing process, so that the dust will be raised and the carbon brush material blocks will be swept into the inner cavity of the circular grinding bin 8. After the material blocks enter the inner cavity of the circular grinding bin 8, the rotating ends of the electric drive rollers 81 will bring the grinding blades 82 to continuously flip the carbon brush material blocks. When the grinding blades 82 flip the material blocks, the material blocks will continuously contact the grinding medium in the inner cavity of the circular grinding bin 8, so that the grinding medium in the inner cavity of the circular grinding bin 8 will further contact and grind with the surface of the carbon brush material blocks, thereby further ensuring the grinding effect of the surface of the carbon brush material blocks.

[0051] Embodiment 2:

[0052] Based on the first embodiment, it is considered in this embodiment that the carbon brush material block can be vertically transported by the vertical grinding tube 6, but the descending rate of the carbon brush material block cannot be slowed down during the transportation process, which easily leads to the breakage of the carbon brush material block. At the same time, it is difficult to effectively grind the lateral outer surface of the carbon brush in the screening and grinding step. Therefore, a vertical grinding deceleration unit is provided in this embodiment to avoid the above problems.

[0053] A vertical grinding and deceleration unit is arranged at the bottom of the conveying channel 13, and the vertical grinding and deceleration unit includes a vertical grinding pipe 6, which is connected and installed at the bottom of the conveying channel 13, and a unloading channel 63 is arranged in the central area of ​​the vertical grinding pipe 6, and grinding rollers 61 are symmetrically installed on both sides of the vertical grinding pipe 6, and a flexible grinding belt 62 is installed on the outer surface of the grinding roller 61.

[0054] In this embodiment, after the top and bottom of the carbon brush block are polished and smooth, the block that meets the screening specifications of the conveying channel 13 will fall into the vertical polishing tube 6 through the conveying channel 13. Because in the previous polishing step, the carbon brush block can only be flipped and polished in the forward and reverse directions along the X-axis state, and the carbon brush block cannot be parallel polished in the Z-axis state, the lateral surface of the carbon brush cannot be effectively polished. The flexible polishing belt 62 in the vertical polishing tube 6 will slow down the falling speed of the block to prevent the carbon brush block from breaking due to excessive feeding speed. At the same time, the polishing rollers 61 and the flexible polishing belt 62 on both sides of the vertical polishing tube 6 perform contact polishing on the lateral surroundings of the surface of the carbon brush block, so that the lateral surface of the block can be fully in contact with the flexible polishing belt 62, further ensuring the polishing effect of the lateral surface of the carbon brush block.

[0055] A method, based on the above-mentioned positioning-based carbon brush grinding processing equipment, includes the following steps:

[0056] S1: The transported carbon brush blocks are centrally guided and transported to the transport channel 13 area. During the transport process, in order to ensure the material block discharge rate, the first stepper motor 43 can be driven to rotate intermittently, so that the guide inclined plate 41 can be slowly swung, so that the material block discharge rate on the guide inclined plate 41 is accelerated, thereby ensuring the material block discharge rate;

[0057] S2: When the rotating end of the driving roller 58 rotates, the push rotating plate 56 can be driven to rotate. At this time, the oblique shovel plates 57 installed on both sides of the push rotating plate 56 will shovel the carbon brush material block to turn it over during the rotation process, so that the carbon brush material block is turned over, ensuring that the bottom surface of the carbon brush material block can also be effectively polished, ensuring that the polishing effect of the top and bottom of the carbon brush material block is improved;

[0058] S3: The flexible grinding belt 62 in the vertical grinding tube 6 will reduce the falling speed of the material block to prevent the carbon brush material block from being broken due to the excessive feeding speed. At the same time, the grinding rollers 61 and the flexible grinding belt 62 on both sides of the vertical grinding tube 6 perform contact grinding on the lateral periphery of the surface of the carbon brush material block, so that the lateral surface of the material block can fully contact with the flexible grinding belt 62, further ensuring the grinding effect of the lateral surface of the carbon brush material block;

[0059] S4: After the material block enters the inner cavity of the circular grinding bin 8, the rotating end of the electrically driven roller 81 will bring the grinding blades 82 to continuously flip the carbon brush material block. When the grinding blades 82 flip the material block, the material block will continuously contact with the grinding medium in the inner cavity of the circular grinding bin 8, so that the grinding medium in the inner cavity of the circular grinding bin 8 will further contact and grind with the surface of the carbon brush material block, thereby further ensuring the grinding effect of the surface of the carbon brush material block.

[0060] Working principle: During the use of the device, the cut carbon brush blocks are first placed on the surface of the conveyor line 31 between the adjacent lateral frames 3, and then the conveyor line 31 is driven to convey the part of the blocks. The conveyor line 31 will convey the blocks to the surface of the dredging inclined plate 41. The surface of the dredging inclined plate 41 is inclined. During the conveying process, the dredging curved plate 4 is narrowed from wide to narrow, so that the conveyed carbon brush blocks are centrally guided and conveyed to the conveying channel 13 area. At the same time, during the conveying process, in order to ensure the unloading rate of the blocks, the intermittent rotation of the first stepper motor 43 can be driven to make the dredging inclined plate 41 swing slowly, so that the unloading rate of the blocks on the dredging inclined plate 41 is accelerated;

[0061] After the blocking block falls into the area of ​​the conveying channel 13, the annular guide rail 5 can be driven, and the rotating end of the annular guide rail 5 will drive the lower top plate 52 to rotate. When the lower top plate 52 rotates, it drives the upper top plate 54 to rotate. During the rotation of the upper top plate 54, the moving end of the movable cylinder 53 on the top of the lower top plate 52 is driven to descend. After the moving end of the movable cylinder 53 descends, the grinding brush strip 55 will pass through the through groove 521 and come into contact with the carbon brush block in the area of ​​the conveying channel 13, and then accelerate the output power of the annular guide rail 5, thereby improving the rotation of the lower top plate 52 and the upper top plate 54. The moving speed makes the brush strip 55 effectively fit and grind the top surface of the carbon brush block. In the process of fitting and grinding the surface of the carbon brush block, in order to ensure that the bottom of the carbon brush block can also be effectively polished by the brush strip 55, the driving roller 58 can be rotated. When the rotating end of the driving roller 58 rotates, the push rotating plate 56 can be driven to rotate. At this time, the oblique shovel plates 57 installed on both sides of the push rotating plate 56 will shovel the carbon brush block during the rotation process to turn it over, so that the carbon brush block is turned over, ensuring that the bottom surface of the carbon brush block can also be effectively polished;

[0062] When the top and bottom of the carbon brush block are polished and smooth, the block that meets the screening specifications of the conveying channel 13 will fall into the vertical polishing tube 6 through the conveying channel 13. Since in the previous polishing step, the carbon brush block can only be polished in the forward and reverse directions along the X-axis state, and the carbon brush block cannot be polished in parallel along the Z-axis state, the lateral surface of the carbon brush cannot be effectively polished. The flexible polishing belt 62 in the vertical polishing tube 6 will reduce the falling speed of the block to prevent the carbon brush block from being broken due to excessive feeding speed. At the same time, the polishing rollers 61 and the flexible polishing belt 62 on both sides of the vertical polishing tube 6 perform contact polishing on the lateral surroundings of the surface of the carbon brush block, so that the lateral surface of the block can be fully in contact with the flexible polishing belt 62.

[0063] The polished material block is conveyed to the conveying inclined surface 71 on the surface of the conveying guide platform 7 through the vertical polishing tube 6. The moving ends of the inclined guide rails 72 embedded on both sides of the conveying guide platform 7 will drive the moving arms 74 to move back and forth. During the movement of the moving arms 74, the pushing bars 75 will be driven to push the carbon brush material block to unload the material. At the same time, the dust generated during the polishing process will be swept up during the pushing process, so that the dust will be raised and the carbon brush material block will be swept into the inner cavity of the circular polishing bin 8. When the material block enters the inner cavity of the circular polishing bin 8, the rotating end of the electric drive roller 81 will bring the polishing blades 82 to continuously flip the carbon brush material block. When the polishing blades 82 flip the material block, the material block will continuously contact the polishing medium in the inner cavity of the circular polishing bin 8, so that the polishing medium in the inner cavity of the circular polishing bin 8 will further contact and polish the surface of the carbon brush material block.

[0064] When the grinding medium contacts and grinds the surface of the carbon brush block, the dust generated on the surface of the carbon brush due to grinding will be fully lifted up by the grinding blades 82. The raised dust can reduce the dust adhesion problem on the surface of the grinding medium. At the same time, the dust raised by the push bar 75 and the dust raised by the grinding blades 82 can be respectively absorbed and filtered in different areas through the first-level adsorption bin 91 and the second-level adsorption bin 92, so that the raised dust can be quickly extracted and filtered.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

4. A method, based on the positioning-based carbon brush grinding processing equipment according to claim 3 above, It is characterized in that The steps include: S1: The transported carbon brush blocks are centrally guided and transported to the transport channel (13) area. During the transport process, in order to ensure the material block discharge rate, the first stepper motor (43) can be driven to rotate intermittently, so that the guide inclined plate (41) slowly swings, so that the material block discharge rate on the guide inclined plate (41) is accelerated, thereby ensuring the material block discharge rate; S2: When the rotating end of the driving roller (58) rotates, the push rotating plate (56) can be driven to rotate. At this time, the oblique shovel plates (57) installed on both sides of the push rotating plate (56) will shovel the carbon brush material block to turn it over during the rotation process, so that the carbon brush material block is turned over, ensuring that the bottom surface of the carbon brush material block can also be effectively polished, thereby ensuring that the polishing effect of the top and bottom of the carbon brush material block is improved; S3: The flexible grinding belt (62) in the vertical grinding tube (6) slows down the falling speed of the material block, thereby preventing the carbon brush material block from being broken due to being dropped too quickly. At the same time, the grinding rollers (61) and the flexible grinding belt (62) on both sides of the vertical grinding tube (6) perform contact grinding on the lateral periphery of the surface of the carbon brush material block, so that the lateral surface of the material block can fully contact with the flexible grinding belt (62), thereby further ensuring the grinding effect of the lateral surface of the carbon brush material block; S4: After the material block enters the inner cavity of the circular grinding chamber (8), the rotating end of the electrically driven roller (81) will drive the grinding blade (82) to continuously flip the carbon brush material block. When the grinding blade (82) flips the material block, the material block will continuously contact the grinding medium in the inner cavity of the circular grinding chamber (8), so that the grinding medium in the inner cavity of the circular grinding chamber (8) further contacts and grinds with the surface of the carbon brush material block, thereby further ensuring the grinding effect of the surface of the carbon brush material block.
