[0002] The rotor pole shoe is a part used for the motor rotor. The outer surface of the rotor pole shoe is an arc surface.

The connecting plate 7 cooperates with the power mechanism 6 to enable the connecting plate 7 to reciprocate horizontally at the bottom of the top plate 2. A clamping mechanism 8 is provided on the surface of the connecting plate 7. When the connecting plate 7 drives the clamping mechanism 8 to be located on one side of the moving groove 4, the clamping mechanism 8 can adsorb the rotor pole shoe on the first processing position 18 through air negative pressure to achieve a fixed clamping effect. Compared with the traditional mechanical clamping method, negative pressure adsorption can prevent indentations from being left on the surface of the rotor pole shoe, which helps to improve the quality of rotor pole shoe processing. The exhaust end of the fan 3 is connected to a connecting box 9 through a pipeline. The bottom of the connecting box 9 is bolted to the top of the top plate 2 through a support. The other end of the top of the top plate 2 An air storage tank 10 is bolted to the side through a supporting base. The air storage tank 10 and the connecting box 9 are interconnected through a pipeline, so that the airflow discharged from the exhaust end of the fan 3 can be transported to the inside of the air storage tank 10 through the connecting box 9. An air outlet pipe 13 is provided on one side of the air storage tank 10. One end of the air outlet pipe 13 passes through the bottom of the top plate 2, and the air outlet pipe 13 is interconnected with the movable groove 4. A storage cavity 14 is provided on one side of the movable groove 4. The width of the storage cavity 14 is greater than that of the movable groove 4. A blocking mechanism 12 is provided in the inner cavity of the storage cavity 14. The blocking mechanism 12 is used in conjunction with the air outlet pipe 13 to block the bottom end of the air outlet pipe 13, so that the air storage tank 10 can form a closed container, and the air discharged from the fan 3 is compressed and stored. The air storage tank 10 The inner cavity is provided with an auxiliary mechanism 11, which can filter impurities in the air flow flowing into the gas tank 10 to improve the purity of the gas stored in the gas tank 10, and can also prevent the compressed gas stored in the gas tank 10 from flowing back to the fan 3. When the power mechanism 6 drives the connecting plate 7 to move to the side of the movable groove 4 close to the storage cavity 14, the clamping mechanism 8 will move the rotor pole shoe to the top of the second processing position 17. At this time, the clamping mechanism 8 can make the blocking mechanism 12 release the blocking of the bottom end of the outlet pipe 13, so that the compressed gas stored in the gas tank 10 can be input into the clamping mechanism 8, and then the negative pressure adsorption on the surface of the rotor pole shoe can be released, so that the rotor pole shoe falls into the second processing position 17 below for subsequent processing operations.

[0027] The power mechanism 6 includes a driving motor 61, which is bolted to one side of the top plate 2 through a support plate, and a screw rod 62 is bolted to the output shaft of the driving motor 61. One end and the surface of the screw rod 62 are rotatably connected to the support plate with a bearing seat, so that it can remain stable during rotation. The surface of the screw rod 62 is threadedly connected to a thread block 63, and the top of the thread block 63 is slidably connected to the top of the top plate 2. One side of the thread block 63 is bolted to the connecting plate 7. When the driving motor 61 provides power to drive the screw rod 62 to rotate, the thread block 63 can be restricted by the sliding connection between the thread block 63 and the bottom of the top plate 2, and the screw block 63 can be rotated along the screw rod 6 2 is moved, so that the threaded block 63 can drive the connecting plate 7 to reciprocate at the bottom of the top plate 2, and the moving connecting plate 7 can drive the clamping mechanism 8 to reciprocate along the moving groove 4, thereby the clamping mechanism 8 can drive the rotor pole shoe that is adsorbed and fixed to move from the first processing position 18 to the second processing position 17 for subsequent processing operations. A slider 15 is bolted to one side of the connecting plate 7, and a slide groove frame 16 is bolted to one side of the bottom of the top plate 2. The slider 15 is slidably connected to the inner wall of the slide groove frame 16, which can not only improve the load capacity of the connecting plate 7, but also make the connecting plate 7 more stable and smooth when moving.

[0028] The clamping mechanism 8 includes a hydraulic rod 81, which is bolted to one side of the bottom of the connecting plate 7. The output end of the hydraulic rod 81 is bolted to an arc shell 82. The top of the connecting plate 7 is fixedly connected to a block 86, which is used in conjunction with the blocking mechanism 12. The top of the arc shell 82 is connected to a hose 83, and the top of the hose 83 passes through the top of the connecting plate 7 and the block 86. The top of the hose 83 is connected to a sealing ring 84. The diameter of the sealing ring 84 is the same as the diameter of the intake pipe 5. The top of the sealing ring 84 is slidably connected to the top of the inner wall of the movable groove 4 and fits tightly to each other. The diameter of the arc shell 82 corresponds to the diameter of the rotor pole shoe to be processed. The bottom of the arc shell 82 The upper and lower parts of the air inlet pipe 5 are connected to each other with a plurality of suction cups 85, and the position distribution of the suction cups 85 corresponds to the position of the surface of the rotor pole shoe. The corresponding arc shell 82 can be replaced according to the specifications of the rotor pole shoe to be processed. When in use, the hydraulic rod 81 is started to extend the output end to drive the arc shell 82 downward to fit the rotor pole on the first processing position 18, so that the suction cup 85 can contact the surface of the rotor pole shoe, and when the position of the sealing ring 84 corresponds to the bottom end of the air inlet pipe 5, the sealing effect of the sealing ring 84 makes the hose 83 and the air inlet pipe 5 form an effect of mutual communication. At this time, the fan 3 draws the air in the hose 83 and the arc shell 82 through the air inlet pipe 5. At this time, since the suction cup 85 fits the surface of the rotor pole shoe, A negative pressure effect is formed in the arc shell 82 and the hose 83, and the suction cup 85 can stably adsorb the surface of the rotor pole shoe through the negative pressure, so as to achieve the purpose of fixed clamping, effectively avoiding the problem of indentations on the surface of the rotor pole shoe that may be caused by traditional mechanical clamping. At the same time, the suction cup 85 can also suck in and clean the fine metal debris generated on the surface of the rotor pole shoe due to processing. These metal debris will eventually be transported to the inside of the air storage tank 10 with the air flow and filtered by the auxiliary mechanism 11. In addition, the output end of the hydraulic rod 81 can be retracted to lift the rotor pole shoe out of the support of the first processing position 18, and the connecting plate 7 can be driven by the power mechanism 6 to move toward the storage chamber 14, so that the rotor pole shoe can be removed from the first processing position 18. The first processing position 18 moves to above the second processing position 17. During this process, the sealing ring 84 will slide and move closely against the top of the inner wall of the movable groove 4, so that the inner cavity of the arc shell 82 and the hose 83 can always remain sealed, and the output end of the hydraulic rod 81 will also drive the rotor pole shoe to slowly descend through the arc shell 82 until the block 86 releases the blocking of the sealing mechanism 12 on the air outlet pipe 13. At this time, the sealing ring 84 will be connected to the air outlet pipe 13, and the compressed gas in the air storage tank 10 can be input into the interior of the arc shell 82 through the hose 83, so that the suction cup 85 can release the negative pressure adsorption on the surface of the rotor pole shoe, so that it falls onto the second processing position 17 for subsequent processing operations.

[0029] The auxiliary mechanism 11 includes a support frame 112, which is bolted to the inner wall of the gas tank 10, and a filter plate 113 is slidably connected in the support frame 112. A pickup door 111 is hinged on the surface of the gas tank 10, and the surface of the gas tank 10 is fixedly connected to the other side of the pickup door 111 by bolts. The pickup door 111 can be opened by removing the bolts. A rubber pad is provided between the pickup door 111 and the gas tank 10 to increase the sealing between them and prevent gas leakage. When the exhaust end of the fan 3 inputs the airflow into the gas tank 10 through the pipeline and the connecting box 9, the filter plate 113 can filter and intercept metal debris in the airflow, thereby improving the purity of the gas discharged from the gas tank 10, and by opening or closing the pickup door 111, it is convenient for the operator to operate the filter plate 113. Cleaning and replacement, a horizontal bar 114 is bolted to one side of the top of the inner wall of the connecting box 9, and a baffle 115 is hinged at the bottom of the horizontal bar 114. The size of the baffle 115 corresponds to the size of the inner wall of the connecting box 9. When the baffle 115 is in an upright state, it will fit into the pipe on one side of the connecting box 9, thereby preventing the flow of gas in the connecting box 9. When the exhaust end of the fan 3 conveys the airflow to the inside of the connecting box 9 through the pipe, the baffle 115 will be driven by the airflow to rotate and tilt to the other side of the inner cavity of the connecting box 9, thereby not affecting the smooth flow of the airflow through the connecting box 9 to the gas storage tank 10. When the fan 3 stops running, the air pressure in the gas storage tank 10 will restore the baffle 115 to an upright state and fit with the pipe on one side of the connecting box 9, thereby preventing the compressed gas stored in the gas storage tank 10 from flowing out in the opposite direction through the connecting box 9.

[0030] The sealing mechanism 12 includes a vertical plate 121, which is located in the inner cavity of the storage chamber 14. The vertical plate 121 is slidably connected to the inner wall of the storage chamber 14. A support plate 124 is bolted to one side of the vertical plate 121. The support plate 124 extends to the inner cavity of the movable groove 4 and is slidably connected to its inner wall. Since the width of the storage chamber 14 is greater than the width of the movable groove 4, the vertical plate 121 will not move into the inner cavity of the movable groove 4. A sealing gasket 122 is bolted to the top of the support plate 124. The top of the sealing gasket 122 fits with the top of the inner wall of the movable groove 4 and is slidably connected to each other. The diameter of the sealing gasket 122 is greater than the diameter of the outlet pipe 13. When the sealing gasket 122 fits with the bottom end of the outlet pipe 13, a sealing effect can be provided for the gas storage tank 10. The inner cavity of the storage chamber 14 is provided with a spring 123. The spring 1 The number of 23 is two and they are symmetrically distributed. The two ends of the spring 123 are in contact with the inner wall of the storage chamber 14 and one side of the vertical plate 121 respectively. When the connecting plate 7 drives the stopper 86 to move toward one side of the storage chamber 14 in the movable groove 4, the stopper 86 will contact and squeeze with the support plate 124, thereby pushing the support plate 124 and the sealing gasket 122 to move into the inner cavity of the storage chamber 14, so that the sealing gasket 122 releases the blocking effect on the air outlet pipe 13, and the vertical plate 121 will compress the spring 123. When the stopper 86 is separated from the squeezing contact with the support plate 124, under the elastic action of the spring 123, the support plate 124 and the sealing gasket 122 can be pushed out of the storage chamber 14 and into the movable groove 4 through the vertical plate 121, and continue to provide a blocking effect on the bottom end of the air outlet pipe 13.

[0031] It is worth noting that the second processing position 17 and the first processing position 18 proposed in the present technical solution are both prior arts, and their working principles and beneficial effects when used are not described in detail here.

[0032] Working principle: First, start the hydraulic rod 81 to drive the arc shell 82 to move downward, so that the suction cup 85 fits with the surface of the rotor pole shoe on the first processing position 18, and then start the fan 3 to form a negative pressure by pumping the air in the hose 83 and the inner cavity of the arc shell 82 through the cooperation of the air inlet pipe 5 and the sealing ring 84, so that the suction cup 85 adsorbs the surface of the rotor pole shoe to achieve the effect of fixing it. At the same time, the suction cup 85 can also suck in the fine metal debris on the surface of the rotor pole shoe. These debris will pass through the pipe at the exhaust end of the fan 3 with the air flow. The gas is finally transported to the gas storage tank 10 for compression and storage through the channel and the connecting box 9, and the filter plate 113 can filter the metal debris in the air flow, which can improve the purity of the gas in the gas storage tank 10, and then the hydraulic rod 81 is retracted to drive the rotor pole shoe to rise. In the next step, the drive motor 61 is started to drive the screw rod 62 to rotate, so that the threaded block 63 drives the connecting plate 7 to move, so that the stopper 86 and the sealing ring 84 can move along the moving groove 4 toward the storage chamber 14, so that the rotor pole shoe can move from the first processing position 18 to the second processing position 17. During this process, the sealing ring 84 will slide closely against the top of the inner wall of the moving groove 4, so that the arc shell 82 and the hose 83 are always in a sealed negative pressure state, and the output end of the hydraulic rod 81 will also slowly drop. When the stopper 86 contacts the support plate 124, the support plate 124 and the sealing gasket 122 can be pushed into the storage chamber 14, so that the sealing gasket 122 releases the blockage of the outlet pipe 13, and the vertical plate 121 compresses the spring 123 until the sealing ring 84 and the outlet pipe 13 are connected to each other, so that the gas storage tank The compressed gas stored in 10 is input into the interior of the arc shell 82 through the hose 83, so that the suction cup 85 can release the negative pressure adsorption on the surface of the rotor pole shoe and make it fall into the second processing position 17. The staff can then perform processing operations on the rotor pole shoe. Finally, the connecting plate 7 is used through the power mechanism 6 to drive the stopper 86 to disengage from the support plate 124. Under the elastic action of the spring 123, the vertical plate 121 can push the support plate 124 to leave the storage chamber 14 and enter the movable groove 4 to continue to block the bottom end of the outlet pipe 13.
