Description

Technical Field

[0001] The invention relates to the technical field of flywheel processing, in particular to a flywheel processing and grinding device. Background Art

[0002] A flywheel is a mechanical device that is mainly used to store rotational kinetic energy and release it when needed. It can be used to smooth movement, adjust speed fluctuations, and provide additional power support. It is widely used in the automotive industry, power plants, power tools and other fields. Flywheels are usually manufactured through a casting process. One side of the flywheel is usually provided with a stepped surface for mounting a clutch plate and a pressure plate. The center of the flywheel is provided with a through hole that matches the crankshaft, circumferentially evenly arranged limiting holes, and mounting holes between the limiting holes and the through holes. The outermost part of the flywheel is a gear ring for meshing with transmission system components. In order to remove burrs and sharp edges on the surface of the flywheel after molding and improve its surface finish, the surface of the flywheel after machining needs to be polished to ensure its performance and stability and improve the working efficiency and service life of the flywheel.

[0003] However, the following problems still exist in the process of grinding flywheels: (1) When grinding the step surface, it is necessary to grind the surface of each step segment one by one, which has a low overall efficiency. In addition, it is difficult to keep the grinding force on different step surfaces uniform and the same, making it difficult to ensure the consistency of the grinding degree and effect of different step surfaces. The overall grinding effect needs to be improved.

[0033] During specific operation: in the initial state, the distance between the grinding unit 3 and the fixing unit 2 is the largest so as to place the flywheel. First, the flywheel to be polished can be placed on the upper end of the processing truncated table 1 with the stepped surface of the flywheel facing upwards. During the placement of the flywheel, the limiting holes and mounting holes on the flywheel can be inserted into the insert rod 1 211 and the insert rod 212 on the upper end of the processing truncated table 1 respectively, and the upper end surfaces of the insert rod 1 211 and the insert rod 212 are flush with the stepped planes corresponding to the flywheel, just completing the sealing of the corresponding limiting holes and mounting holes, thereby preventing subsequent grinding chips from entering the limiting holes or mounting holes and ensuring the cleanliness of the flywheel. The flywheel can be circumferentially limited by the cooperation between the insert rod 1 211 and the limiting holes, and the insert rod 212 and the mounting holes to prevent the flywheel from rotating during the subsequent polishing process. In addition, at this time, the circumferentially arranged fan-shaped plates 214 are all in a downwardly inclined raised state, and the through hole in the middle of the flywheel can smoothly pass through the circumferentially arranged fan-shaped plates 214 and the mounting rod 213.

The sizes are adapted, and the rough grinding part includes an upper grinding plate 312, a sliding groove 313 is opened at the upper end of the upper grinding plate 312, and two pressure plates 314 are installed in the sliding groove 313 along the radial sliding of the center rod 32. The upper end of the pressure plate 314 is hinged with a connecting plate 315, and the other ends of the two connecting plates 315 are hinged to the lower end of the upper support plate 311. The side end of the pressure plate 314 away from the center rod 32 in the sliding groove 313 is installed with a side grinding plate 317 through an elastic telescopic rod 316, and the lower end of the upper grinding plate 312 and the side of the side grinding plate 317 away from the corresponding pressure plate 314 are both provided with a rough grinding layer.

[0035] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 The fine grinding assembly includes a lower support plate 321 that slides up and down with the center rod 32 through a spline and is located below the upper support plate 311. An upper spring 322 that is sleeved on the outside of the center rod 32 is connected between the upper support plate 311 and the lower support plate 321. A lower spring 323 that is sleeved on the outside of the center rod 32 is connected between the lower support plate 321 and the lower end surface of the center rod 32. A fine grinding piece arranged radially along the center rod 32 is provided at the position of the lower end of the lower support plate 321 corresponding to the step surface of the flywheel. The fine grinding piece has the same structure as the corresponding coarse grinding piece, but a fine grinding layer is provided on the lower end of the upper grinding plate 312 and the side grinding plate 317 in the fine grinding piece away from the corresponding pressure plate 314.

[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6A downward moving assembly for controlling the overall downward movement of the grinding unit 3 is arranged above the processing circular table 1. The downward moving assembly includes two guide columns 111 installed on the upper end of the processing circular table 1 and distributed on the left and right sides of the grinding unit 3. Side plates that slide up and down with the corresponding guide columns 111 are installed on the left and right sides of the moving circular plate 31. A motor 112 is installed on the upper end of the moving circular plate 31 through a mounting bracket. The output shaft of the motor 112 rotates through the moving circular plate 31 and is connected to the upper end of the center rod 32. The upper ends of the left and right guide columns 111 are connected to each other. A top plate 113 is installed, and a hydraulic cylinder 114 whose pushing end is connected to the mounting support is installed on the top plate 113. An annular frame 115 is installed between the left and right guide columns 111. Moving blocks 116 are slidably installed at the upper ends of the annular frame 115 corresponding to the upper support plate 311 and the lower support plate 321. Guide rods 117 that slide up and down with the corresponding upper support plate 311 and lower support plate 321 are respectively installed on the upper ends of the two moving blocks 116. A telescopic spring 118 is sleeved on the outside of the guide rod 117 corresponding to the lower support plate 321.

[0037] After the flywheel is placed, the hydraulic cylinder 114 can push the grinding unit 3 to move downward as a whole through the mounting support. During this process, the movable circular plate 31 drives the motor 112, the center rod 32, the coarse grinding assembly and the fine grinding assembly to move downward synchronously through the side plate along the left and right guide columns 111. The guide column 111 can support and guide the downward movement of the grinding unit 3. As the grinding unit 3 moves downward, the center rod 32 gradually contacts the upper end of the mounting rod 213 and presses the mounting rod 213 to move downward along the fixing ring 215 and the circular hole. The mounting rod 213 drives the circumferentially arranged fan-shaped plates 214 to move downward synchronously through the compression connecting spring 217. Under the action of the fixing ring 215 and the connecting rod 216, the fan-shaped plates 214 gradually become horizontally opened. The fan-shaped plates 214 in the opened state can just press against the inner wall of the flywheel through hole and complete its blocking.

[0038] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 A guide ring 119 is installed on the inner side of the annular frame 115, and an annular groove 121 is provided on the inner ring wall of the guide ring 119. A moving rod 122 that slides with the annular groove 121 is installed on the side end of the pressure plate 314 near the annular groove 121 in the rough grinding component. An open groove that communicates with the annular groove 121 is provided at the position of the moving rod 122 at the upper end of the guide ring 119. A circular ring 123 that rotatably cooperates with the lower end of the center rod 32 is installed on the upper end of the mounting rod 213. An annular limiting groove 124 is provided on the outer ring surface of the circular ring 123. A stop plate 125 is installed on the side end of the pressure plate 314 near the center rod 32 in the rough grinding component.

[0039] When the center rod 32 moves down to abut against the mounting rod 213, the coarse grinding assembly and the fine grinding assembly move down to the upper end of the flywheel synchronously. During this process, the center rod 32 drives the upper support plate 311 and the lower support plate 321 to move down synchronously through the upper spring 322 and the lower spring 323. The upper support plate 311 and the lower support plate 321 respectively drive the corresponding coarse grinding assembly and the fine grinding assembly to move downward synchronously. The upper support plate 311 and the lower support plate 321 respectively move downward along the corresponding guide rod 117. The guide rod 117 can guide and support the corresponding coarse grinding assembly or the fine grinding assembly. With the cooperation with the connecting block 310, several upper grinding plates 312 move downward synchronously until the upper grinding plates 312 in different rough grinding parts simultaneously fit the corresponding step surface parts of the upper end of the flywheel, and the pressure plate 314 close to the annular groove 121 in the rough grinding part drives the moving rod 122 to move to the position of the opening groove and is located on the inner side of the annular groove 121 of the guide ring 119, and the pressure plate 314 close to the center rod 32 in the rough grinding part drives the abutment plate 125 to move to be opposite to the annular limit groove 124 on the circular ring 123, but the upper grinding plates 312 in the fine grinding assembly do not fit the step surface of the flywheel.

[0040] See also Figure 4 and Figure 5 The lower end of the movable circular plate 31 is provided with an adjustment component for adjusting the angle between the two connecting plates 315 corresponding to the same upper grinding plate 312. The adjustment component includes an inner annular groove 329 opened at the lower end of the movable circular plate 31, a column 341 slidably connected to the inner annular groove 329 is installed on the upper end of the upper support plate 311, a wedge block 342 slidably matched with the inner annular groove 329 and the column 341 is provided at the lower end of the movable circular plate 31, an outer annular groove 324 located outside the inner annular groove 329 is opened at the lower end of the movable circular plate 31, and a wedge block 342 slidably matched with the inner annular groove 329 and the column 341 is installed at the upper end of the lower support plate 321. The column 2 325 is slidably connected to the outer annular groove 324, and the position of the wedge block 1 342 at the lower end of the movable circular plate 31 is provided with a wedge block 2 326 that slidably cooperates with the outer annular groove 324 and the column 2 325. The outer annular groove 324 and the inner annular groove 329 are both concentric with the movable circular plate 31. The circumferential length of the wedge block 2 326 is greater than the circumferential length of the wedge block 1 342. The rear sides of the wedge block 1 342 and the wedge block 2 326 are slidably cooperated with a T-shaped clamping plate 327. The right end of the T-shaped clamping plate 327 is connected to the pushing end of the electric push rod 328 installed at the lower end of the right side plate.

[0041] See also Figure 1-Figure 7During operation, S1: after the coarse grinding assembly and the fine grinding assembly move down to the upper end of the flywheel, the motor 112 can be used to drive the center rod 32 to rotate counterclockwise, and the center rod 32 drives the upper support plate 311 and the lower support plate 321 to rotate synchronously through the spline. When the upper support plate 311 rotates, it drives the column 1 341 to move synchronously along the inner annular groove 329, and the column 1 341 gradually moves to cooperate with the wedge block 1 342. Under the cooperation of the inclined surfaces of the column 1 341 and the wedge block 1 342, the upper support plate 311 compresses the upper spring 322. The upper support plate 311 drives the rough grinding assembly to move downward synchronously. At this time, the upper grinding plate 312 in the rough grinding piece has already hit the step surface of the flywheel and cannot move downward. Therefore, in this process, the two connecting plates 315 in the same rough grinding piece rotate synchronously around the hinge point between it and the upper support plate 311, and the angle between the two increases. At the same time, downward pressure is applied to the pressure plate 314. The two connecting plates 315 and the corresponding upper grinding plates 312 form a triangular structure, which is conducive to improving the corresponding upper grinding plates 312 during the grinding process. In order to improve the stability, during the process of gradually increasing the angle between the two connecting plates 315, the two connecting plates 315 push the corresponding pressing plates 314 to move synchronously in the opposite direction along the sliding groove 313 on the upper grinding plate 312, and at the same time, the side grinding plate 317 always contacts and fits with the vertical part of the flywheel step surface through the cooperation between the elastic telescopic rod 316 and the corresponding pressing plate 314, so as to grind the vertical part of the flywheel step surface later. With the synchronous reverse movement of the two pressing plates 314 on the same upper grinding plate 312, the pressing plate 31 The greater the force acting on the corresponding upper grinding plate 312, the greater the grinding force applied by the upper grinding plate 312 on the step surface of the flywheel, and the higher the grinding degree of the step surface of the flywheel. Under the elastic force of the elastic telescopic rod 316, the tightness between the side grinding plate 317 and the vertical part of the step surface of the flywheel also gradually increases, and the grinding degree of the vertical part of the step surface of the flywheel increases synchronously. In addition, the upper grinding plate 312 pressed against the upper end of the step surface of the flywheel can further fix the flywheel to prevent the flywheel from moving up and down and affecting the grinding effect.

[0042] S2: When the column 1 341 is completely moved to match the wedge block 1 342, the upper support plate 311 just controls the corresponding pressing plate 314 to press the upper grinding plate 312 through the connecting plate 315. At this time, the moving rod 122 moves into the annular groove 121, and the abutment plate 125 moves into the annular limit groove 124. Then, the electric push rod 328 can drive the T-shaped clamping plate 327 to move away from the wedge block 1 342. At this time, the wedge block 1 342 can move synchronously with the column 1 341 along the inner annular groove 329 As the center rod 32 and the upper support plate 311 continue to rotate, the moving block 116 can rotate synchronously with the upper support plate 311 around the annular frame 115 through the guide rod 117, and the moving rod 122 and the abutment plate 125 can rotate synchronously along the annular groove 121 and the annular limiting groove 124 respectively. At this time, the upper grinding plate 312 in the rough grinding assembly can rough grind the horizontal part of the flywheel step surface through the rough grinding layer, and the side grinding plate 317 can rough grind the vertical part of the flywheel step surface through the rough grinding layer. Under the action of the moving block 116 and the guide rod 117, the moving rod 122 and the annular groove 121, and the abutment plate 125 and the annular limiting groove 124, the rotation of the rough grinding assembly can be guided and limited to ensure the stability of the rough grinding assembly during the grinding process and avoid insufficient adhesion between the upper grinding plate 312 and the flywheel step surface. It should be noted that, although the upper support plate 311 can squeeze the lower support plate 321 through the upper spring 322 to compress the lower spring 323 to move downward while moving downward along the center rod 32, the upper grinding plate 312 in the fine grinding assembly still does not fit the step surface of the flywheel, and the elastic coefficient of the lower spring 323 is greater than the elastic coefficient of the upper spring 322.

[0043] S3: During the rotation of the coarse grinding assembly, the lower support plate 321 drives the fine grinding assembly to rotate synchronously with the center rod 32, and the corresponding moving block 116 and the guide rod 117 can rotate synchronously with the lower support plate 321 along the annular frame 115 to ensure the stability of the fine grinding assembly during rotation. When the fine grinding assembly rotates to the right side of the processing table 1, the second column 325 at the upper end of the lower support plate 321 gradually moves along the outer annular groove 324 at the lower end of the moving circular plate 31 to the position of the second wedge block 326, and the second column 325 gradually cooperates with the second wedge block 326. In the process of the second column 325 moving along the second wedge block 326, the lower support plate 321 is gradually moved downward along the center rod 32 by the inclined surface of the second wedge block 326 and compresses the lower spring 323 and the telescopic spring 118. The lower support plate 321 drives the corresponding upper grinding plate 312 to gradually fit the flywheel step surface through the cooperation between the connecting plate 315 and the pressing plate 314, and the upper grinding plate 312 in the fine grinding assembly is synchronously pressed to the corresponding position of the flywheel step surface in the same way as in the above step S2, and then the T-shaped clamping plate 327 can be driven by the electric push rod 328 to move it away from the wedge block 2 326, and the wedge block 2 326 can rotate synchronously around the outer annular groove 324 with the column 2 325, the lower support plate 321 and the fine grinding assembly as a whole. At this time, the upper grinding plate 312 in the fine grinding assembly can just finely grind the flywheel step surface after rough grinding through the fine grinding layer, and the side grinding plate 317 also performs fine grinding on the vertical part of the flywheel step surface after rough grinding through the fine grinding layer. With the cooperation of the coarse grinding component and the fine grinding component, the coarse and fine grinding of the flywheel can be completed quickly, which not only improves the grinding efficiency but also ensures the smoothness and flatness of the grinding effect. It should be noted that the completely flat surface on the other side of the flywheel can be directly polished using existing technology.

[0044] S4: After the rough grinding assembly and the fine grinding assembly complete the grinding of the flywheel step surface, the upper support plate 311 and the lower support plate 321 can be rotated and reset, and the rough grinding assembly and the fine grinding assembly are reset synchronously. At this time, the upper support plate 311 drives the column 1 341 and the wedge block 1 342 to rotate synchronously to the initial position, and the wedge block 2 326 is not in the initial position. Then, the electric push rod 328 can be used to push the T-shaped clamping plate 327 to make it cooperate with the rear side of the wedge block 1 342, and then the center rod 32 can be rotated in the opposite direction to make the column 1 341 Separated from the wedge block 1 342, the upper support plate 311 moves upward along the center rod 32 under the action of the upper spring 322 to reset, at this time, the plurality of pressure plates 314 in the rough grinding assembly can be reset synchronously with the upward movement of the connecting plate 315 and the upper support plate 311, and the plurality of upper grinding plates 312 are reset to a state just in contact with the step surface of the flywheel. In this process, the abutment plate 125 in the rough grinding assembly gradually moves away from the annular limit groove 124 on the fixed ring 215, and the moving rod 122 gradually moves away from the annular groove 121 on the inner side of the guide ring 119. When the column 1 341 is separated from the wedge block 1 342, the column 2 325 is separated from the wedge block 2 326. Under the action of the lower spring 323 and the telescopic spring 118, the lower support plate 321 can drive the fine grinding assembly to move upward and reset, and the plurality of upper grinding plates 312 in the fine grinding assembly leave the step surface of the flywheel, and then the wedge block 2 326 is manually moved to cooperate with the T-shaped clamping plate 327.

[0045] S5: Then the hydraulic cylinder 114 can be used to control the grinding unit 3 to move up and reset as a whole, so that the upper grinding plates 312 can move away from the flywheel step surface synchronously, and the center rod 32 can move up and gradually move away from the mounting rod 213. At this time, the mounting rod 213 can drive the fan-shaped plate 214 to rotate and reset under the action of the connecting spring 217, thereby releasing the internal clamping of the flywheel through hole. Finally, the grinded flywheel can be removed from the processing table 1.
