Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-5 As shown, this embodiment discloses a disc brake processing device for a hub motor locomotive, including a first drive device 111 and a turning assembly 112. The first drive device 111 controls the lifting and lowering of the turning assembly 112. The turning assembly 112 includes a first gripper 113, a second gripper 114, a first fixing assembly 115, a second fixing assembly 116, a cutting tool 117, and a transmission device 118. The hub motor 4 includes a central shaft 41, which includes a first end 411 and a second end 412. The first gripper 113 and the second gripper 114 can respectively grip the first end 411 and the second end 412 and clamp the hub motor 4. The turning assembly 112 includes an adjustment device 119, which can manually adjust and control the first gripper 113 and the second gripper 114 to adapt to the central shaft 41 of different lengths.

[0025] The first fixing component 115 includes a first push rod 1511, which can abut against the second end 412. The first fixing component 115 is located on the side of the second gripper 114 away from the hub motor 4. The first fixing component 115 includes a first motor 1152, a first lead screw 1153, and a first mounting bracket 1154. The first motor 1152 drives the first lead screw 1153 to rotate. The first mounting bracket 1154 is mounted on the first lead screw 1153. The rotation of the first lead screw 1153 causes the first mounting bracket 1154 to move closer to or away from the second gripper 114. The first push rod 1511 is mounted on the first mounting bracket 1154. The end of the first push rod 1511 facing the second gripper 114 gradually increases in diameter. The reduced cone shape, the second fixing component 116 includes a second push rod 1162, the second push rod 1162 can abut the second end 412, the second fixing component 116 is located on the side of the first gripper 113 away from the hub motor 4, the second fixing component 116 includes a second cylinder 1163, the second cylinder 1163 is connected to the second push rod 1162, the second cylinder 1163 can drive the second push rod 1162 to approach or move away from the first gripper 113, the end of the second push rod 1162 facing the first gripper 113 is a cone with a gradually decreasing diameter, the first push rod 1511 of the first fixing component 115 can position and fix the central shaft 41 with the second push rod 1162 of the second fixing component 116.

[0026] The second fixing assembly 116 includes a sleeve 1161, a second motor 1164, a second lead screw 1165, and a second mounting bracket 1166. The second motor 1164 drives the second lead screw 1165 to rotate. The second mounting bracket 1166 is mounted on the second lead screw 1165. The rotation of the second lead screw 1165 causes the second mounting bracket 1166 to move closer to or away from the first gripper 113. The sleeve 1161 is fixedly mounted on the second mounting bracket 1166. The second push rod 1162 can pass through the sleeve 1161. The sleeve 1161, the second push rod 1162, and the central shaft 41 are coaxially aligned. The central shaft 41 includes a stepped surface 413 facing the sleeve 1161. The sleeve 1161 can be fitted onto the first end 411. The first gripper 113 opens. The second motor 1164 of the second fixing assembly 116 drives the second lead screw 1165. Rotating 65° causes the sleeve 1161 to be fitted onto the central shaft 41 and close to the stepped surface 413 of the central shaft 41. The first fixing component 115 includes a first cylinder 1155, which is mounted on the first mounting bracket 1154. The first cylinder 1155 is connected to the first push rod 1511. The first cylinder 1155 can drive the first push rod 1511 to move closer to or away from the second gripper 114. The first cylinder 1155 of the first fixing component 115 pushes the first push rod 1511 towards the hub motor 4, so that the stepped surface 413 abuts against the sleeve 1161. The central shaft 41 is fixed by the first fixing component 115 and the second fixing component 116, which can eliminate the error gap between the sleeve 1161 and the stepped surface 413, and can firmly fix the central shaft 41, preventing the central shaft 41 from short-circuiting as the hub motor 4 rotates.

[0027] The transmission device 118 includes a rotatable wheel 1181 and a third cylinder 1182. The third cylinder 1182 can drive the wheel 1181 to move closer to or away from the clamped hub motor 4. The wheel 1181 can drive the hub motor 4 to rotate. The wheel 1181 is driven by a motor. The wheel 1181 abuts against the outer peripheral surface of the hub motor 4 and can drive the hub motor 4 to rotate. The hub motor 4 includes a mounting base 42, which includes a mounting surface 421. The cutting tool 117 can move closer to or away from the mounting surface 421. The cutting tool 117 moves horizontally through the second drive device 1171 to perform turning operations with the rotating hub motor 4.

[0028] The sleeve 1161 is equipped with the detection device 101, with the detection end of the detection device 101 facing the mounting surface 421. After the cutting tool 117 processes the mounting surface 421, the rotary wheel 1181 first stops driving the hub motor 4 to rotate, and then drives the hub motor 4 to rotate at multiple angles, so that the detection device 101 can detect the mounting surface 421 to check whether the processing is flat.

[0029] More preferably, the first gripper 113 can also be fitted with an air nozzle. The mounting base 42 has multiple screw holes, and turning debris can easily enter the screw holes. The air nozzle fitted with the first gripper 113 can clean the debris in the screw holes.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
