[0002] In the existing technology, the hub motor has a mounting surface for installing the disc brake disc. Before installing the disc brake disc, the mounting surface needs to be aligned and machined. Existing processing equipment involves manual loading, machining, and unloading of materials one by one, which is slow and inefficient and not suitable for current assembly line processing. Therefore, a technical solution is needed to solve the above problems. Summary of the Invention

[0006] Furthermore, the first fixing component is located on the side of the second gripper away from the hub motor. The first fixing component includes a first motor, a first lead screw, and a first mounting bracket. The first motor drives the first lead screw to rotate. The first mounting bracket is mounted on the first lead screw. The rotation of the first lead screw causes the first mounting bracket to move closer to or away from the second gripper. The first push rod is mounted on the first mounting bracket. The end of the first push rod facing the second gripper is tapered with a gradually decreasing diameter.

[0007] Furthermore, the first fixing component includes a first cylinder, which is mounted on the first mounting bracket and connected to the first push rod. The first cylinder is capable of driving the first push rod to move closer to or away from the second gripper.

[0008] Furthermore, the second fixing component is located on the side of the first gripper away from the hub motor. The second fixing component includes a second cylinder, which is connected to a second push rod. The second cylinder can drive the second push rod to move closer to or away from the first gripper. The end of the second push rod facing the first gripper has a tapered shape with a gradually decreasing diameter.

[0009] Furthermore, the second fixing component includes a sleeve, a second motor, a second lead screw, and a second mounting bracket. The second motor drives the second lead screw to rotate, and the second mounting bracket is mounted on the second lead screw. The rotation of the second lead screw causes the second mounting bracket to move closer to or away from the first gripper. The sleeve is fixedly mounted on the second mounting bracket, and the second push rod can pass through the sleeve. The sleeve, the second push rod, and the central shaft are kept coaxial.

[0010] Furthermore, the central shaft includes a stepped surface facing the sleeve, the sleeve can be fitted onto the first end, the sleeve can abut against the stepped surface, and a detection device is mounted on the sleeve, with the detection end of the detection device facing the mounting surface.

[0011] Furthermore, the processing device includes a limiting component, which includes a limiter and a limiting plate. The limiter is movable and can limit the forward movement of the pallet. The limiting plate is movable and has multiple limiting rods on its upper surface. The pallet includes a bottom plate, which has second limiting holes corresponding to the limiting rods.

[0012] Furthermore, the processing component includes a receiving tray and a receiving hopper. The receiving tray is horizontally retractable and can extend between the turning component and the pallet. The receiving tray is provided with a mounting hole, which is connected to an air pipe. The air pipe can blow air to blow the debris in the receiving tray into the receiving hopper.

[0013] Furthermore, the conveying device includes a first conveyor belt, a steering device, and a second conveyor belt. The first conveyor belt is connected to an external production line. The steering device is located between the first conveyor belt and the second conveyor belt. The processing component is located in the conveying direction of the second conveyor belt. The first conveyor belt receives a pallet fed in from the outside. The first conveyor belt includes a pushing device. The pushing device sends the pallet to the steering device. The steering device rotates the pallet horizontally and sends it into the second conveyor belt. The second conveyor belt sends the pallet to the processing component.

[0014] This invention also discloses an online machining method for hub motors, based on the above-mentioned online machining equipment for disc brakes of hub motors, comprising the following steps:

[0015] S1: There are two processing devices, located on the conveying direction of the second conveyor belt of the conveyor device. The conveyor device has three steering devices, one of which is located at the front of all processing devices, and the other two are located at the rear of the corresponding processing devices. The tray containing the hub motor is sent from the external assembly line to the first conveyor belt of the conveyor device. Check whether the power cord of the hub motor is clamped on the corresponding wire clip of the tray. The first conveyor belt sends the tray to the steering device through the pushing device. The steering device rotates the tray horizontally 180 degrees, so that the wire clip of the tray faces the second conveyor belt. The steering device sends the tray to the second conveyor belt. The second conveyor belt sends the previous tray to the processing device at the rear, and then sends the next tray to the processing device at the front.

[0016] S2: The pallet is conveyed along the second conveyor belt. The limiter of the processing component rises to block the pallet. The limit plate of the processing component rises. The limit rod of the limit plate is inserted into the second limit hole of the pallet. The limit plate lifts the pallet and stops the pallet from being conveyed.

[0017] S3: The first and second jaws of the turning assembly open, the first drive device of the machining assembly drives the turning assembly to descend, the first and second jaws close to clamp the central shaft of the hub motor, and the first drive device drives the turning assembly to rise.

[0018] S4: The receiving tray of the processing component extends out, and the receiving tray extends below the hub motor;

[0019] S5: The first motor of the first fixing component drives the first lead screw to rotate, causing the first push rod to approach the second clamp. The first push rod abuts against the second end of the central shaft of the hub motor. The second cylinder of the second fixing component drives the second push rod to approach the first clamp. The second push rod abuts against the first end of the central shaft of the hub motor. The first clamp opens. The second motor of the second fixing component drives the second lead screw to rotate, causing the sleeve to be fitted onto the central shaft and approach the stepped surface of the central shaft. The first cylinder of the first fixing component pushes the first push rod towards the hub motor, causing the stepped surface to abut against the sleeve. The central shaft is fixed by the first fixing component and the second fixing component.

[0020] S6: The third cylinder of the transmission device drives the rotary wheel to press against the hub motor. The rotary wheel is driven by the motor, and the rotation of the rotary wheel drives the hub motor to rotate. The cutting tool of the turning component approaches the mounting surface of the hub motor to perform turning.

[0021] S7: The rotating wheel drives the hub motor to rotate at multiple angles. The detection device installed on the sleeve tests multiple points on the mounting surface. If the mounting surface is qualified, the hub motor will be sent out. If the mounting surface is unqualified, it will be processed again.

[0022] S8: The receiving tray retracts and leaves below the hub motor. The debris in the receiving tray is blown into the receiving hopper by the air nozzle. The sleeve leaves the central shaft. The first gripper clamps the first end. The first push rod and the second push rod leave the central shaft. The first drive device drives the turning assembly to descend and place the hub motor on the fixture. The first gripper and the second gripper release the central shaft. The first drive device drives the turning assembly to rise. The limit plate descends and retracts. The limiter descends and retracts. The tray is sent out along the second conveyor belt.

[0023] S9: The pallet sent from the processing device is sent to the steering device at the rear end via the receiving device on the second conveyor belt at the rear end. The steering device rotates the pallet horizontally by 180 degrees and sends it out onto the first conveyor belt.

[0024] The beneficial effects of this invention are:

Detailed Implementation

[0039] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1-12As shown, this embodiment discloses a disc brake processing equipment for hub motors on a lathe, including a processing device 1 and a conveying device 2. The conveying device 2 is used to convey a tray 3. The tray 3 includes a base plate 31, a clamp 32, and a wire clamp 33. The clamp 32 and the wire clamp 33 are fixedly installed on the upper surface of the base plate 31. The clamp 32 supports the hub motor 4. The conveying device 2 includes a first conveyor belt 21, a steering device 22, and a second conveyor belt 23. The first conveyor belt 21 is connected to an external production line. The steering device 22 is located between the first conveyor belt 21 and the second conveyor belt 23. There are two processing devices 1, which are located in the conveying direction of the second conveyor belt 23. Each of the two processing devices 1 can process one hub motor 4 simultaneously. The second conveyor belt 23 first sends one tray 3 to the processing device 1 at the rear, and then sends the next tray 3 to the processing device 1 at the front. The hub motors 4 in the two trays 3 can be processed simultaneously, improving processing efficiency and ensuring that the processing time of the front and rear processes of the production line can be coordinated.

[0041] like Figures 9-11As shown, the processing assembly 11 is located in the conveying direction of the second conveyor belt 23. The first conveyor belt 21 receives the tray 3 fed in from the outside. The first conveyor belt 21 includes a pushing device 211, which includes a first blocking device 212 that can be raised and lowered, and four first push rollers 2111 that can be raised and lowered. The first blocking device 212 raises to block the tray 3 fed into the first conveyor belt 21. The four first push rollers 2111 lift the tray 3. The first push rollers 2111 rotate to push the tray 3 toward the turning device 22. The turning device 22 includes conveying mechanisms 222 located on both sides. The second conveyor belt 22 is equipped with multiple conveyor wheels 2221. When the tray 3 enters the steering device 22, it is positioned on the conveyor wheels 2221. The steering device 22 includes a second blocking device 223, which is located on the side near the second conveyor belt 23. The second blocking device 223 includes a rotatable baffle 2231, which is driven to stand up or lower by a rotary cylinder. The steering device 22 also includes a liftable turntable 221, which lifts the tray 3 above it away from the conveyor wheels 2221. The turntable 221 is equipped with a limiting block 2211, which can be inserted into the corresponding position. The tray 3 is inserted into the first limiting hole 311 of the bottom plate 31 of the tray 3. The turntable 221 rotates the tray 3 180 degrees so that the wire clip 33 on the tray 3 faces the side of the second conveyor belt 23. The wire clip 33 of the tray 3 that came in from the previous production line faces the side of the first conveyor belt 21 away from the second conveyor belt 23. In order to prevent the power line of the hub motor 4 from interfering with the cutting tool 117 for turning and to prevent the power line from interfering with the extension of the receiving tray 13, the tray 3 needs to be turned so that the wire clip 33 is on the side of the second conveyor belt 23 away from the first conveyor belt 21. The turning device 22 rotates the tray 3 horizontally and feeds it into the turntable 221. The second conveyor belt 23 includes a lifting and lowering receiving device 231. When the receiving device 231 is raised, it can receive the pallet 3 delivered from the turning device 22. The receiving device 231 is equipped with a second pusher 2311 that can receive the pallet 3. The second pusher 2311 can receive the pallet 3 onto the second conveyor belt 23. The second conveyor belt 23 is provided with a baffle 233, which can limit the pallet 3 entering the second conveyor belt 23. After the receiving device 231 is raised and lowered, the pallet 3 contacts the second conveyor belt 23, and the second conveyor belt 23 delivers the pallet 3 to the processing device 1.

[0042] More preferably, the conveying mechanism 222 is equipped with a guide plate 224, which is located at one end of the conveying mechanism 222 near the first conveyor belt 21. The guide plate 224 provides guidance for the feeding of the tray 3. A transition device 24 is provided between the steering device 22 and the second conveyor belt 23. The transition device 24 includes a rotating rod 241, which can provide support when the tray 3 is sent from the steering device 22 to the second conveyor belt 23, so that the tray 3 can transition better. The second conveyor belt 23 includes a third blocking device 232, which can be inserted into the tray 3 of the second conveyor belt 23 for limiting. A pressure plate 234 is installed on one side of the second conveyor belt 23. The pressure plate 234 is driven to move up and down by a cylinder. The pressure plate 234 can press the wire clip 33 of the tray 3 in the corresponding position to prevent the power line of the hub motor 4 from coming off the wire clip 33.

[0043] like Figures 2-8 As shown, the processing device 1 includes a processing component 11, which includes a first driving device 111, a turning component 112, and a limiting component 12. The limiting component 12 includes a limiter 121 and a limiting plate 122. The limiter 121 can be raised and lowered to limit the forward movement of the pallet 3. The limiting plate 122 can be raised and lowered. The upper surface of the limiting plate 122 is provided with multiple limiting rods 1221. The bottom plate 31 is provided with second limiting holes 312 corresponding to the limiting rods 1221. The limiter 121 and the limiting plate 122 cooperate to pause the pallet 3 below the turning component 112.

[0044] The first drive device 111 controls the lifting and lowering of the turning assembly 112. The turning assembly 112 includes a first jaw 113, a second jaw 114, a first fixing component 115, a second fixing component 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 jaw 113 and the second jaw 114 can respectively clamp the first end 411 and the second end 412 and lift the hub motor 4 away from the fixture 32. The turning assembly 112 includes an adjustment device 119, which can manually adjust and control the first jaw 113 and the second jaw 114 to adapt to the central shaft 41 of different lengths.

[0045] like Figures 6-8As shown, 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 has a diameter of... The second fixing component 116 has a gradually decreasing tapered shape and includes a second push rod 1162. The second push rod 1162 can hold 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 move closer to or away from the first gripper 113. The end of the second push rod 1162 facing the first gripper 113 has a tapered shape 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] The processing component 11 includes a receiving tray 13 and a receiving hopper 14. The receiving tray 13 is horizontally extendable and can extend after the turning component 112 clamps the hub motor 4. The receiving tray 13 can extend between the turning component 112 and the tray 3. The receiving tray 13 receives the chips cut by the cutting tool 117 and prevents the chips from falling into the tray 3. The receiving tray 13 is provided with a mounting hole 131, which is connected to an air pipe. The air pipe can blow air to blow the chips in the receiving tray 13 into the receiving hopper 14. More preferably, the first gripper 113 can also be equipped with an air nozzle. The mounting base 42 is provided with multiple screw holes, and the chips cut by turning can easily enter the screw holes. The air nozzle installed on the first gripper 113 can clean the chips in the screw holes.

[0050] This embodiment also discloses a method for machining hub motors on an inline lathe. The above-mentioned equipment for machining disc brakes on an inline lathe for hub motors includes the following steps:

[0051] S1: There are two processing devices 1, which are located in the conveying direction of the second conveyor belt 23 of the conveying device 2. The conveying device 2 has three steering devices 22, one of which is located at the front end of all processing devices 1, and the other two steering devices 22 are located at the rear end of the corresponding processing devices 1. The tray 3 with the hub motor 4 is sent from the external assembly line to the first conveyor belt 21 of the conveying device 2. Check whether the power cord of the hub motor 4 is stuck on the corresponding wire clip 33 of the tray 3. The first conveyor belt 21 sends the tray 3 to the steering device 22 through the pushing device 211. The steering device 22 rotates the tray 3 horizontally by 180 degrees, so that the wire clip 33 of the tray 3 faces the second conveyor belt 23. The steering device 22 sends the tray 3 to the second conveyor belt 23. The second conveyor belt 23 sends the previous tray 3 to the processing device 1 at the rear, and then sends the next tray 3 to the processing device 1 at the front.

[0052] S2: The tray 3 is conveyed along the second conveyor belt 23. The limiter 121 of the processing component 11 rises to block the tray 3. The limit plate 122 of the processing component 11 rises. The limit rod 1221 of the limit plate 122 is inserted into the second limit hole 312 of the tray 3. The limit plate 122 lifts the tray 3 and the tray 3 stops conveying.

[0053] S3: The first jaw 113 and the second jaw 114 of the turning assembly 112 open, the first drive device 111 of the machining assembly 111 drives the turning assembly 112 to descend, the first jaw 113 and the second jaw 114 close to clamp the central shaft 41 of the hub motor 4, and the first drive device 111 drives the turning assembly 112 to rise.

[0054] S4: The receiving tray 13 of the processing component 11 extends out and extends below the hub motor 4;

[0055] S5: The first motor 1152 of the first fixing component 115 drives the first lead screw 1153 to rotate, causing the first push rod 1511 to approach the second gripper 114. The first push rod 1511 abuts against the second end 412 of the central shaft 41 of the hub motor 4. The second cylinder 1163 of the second fixing component 116 drives the second push rod 1162 to approach the first gripper 113. The second push rod 1162 abuts against the first end 411 of the central shaft 41 of the hub motor 4. The first gripper 113 opens. The second motor 1164 of the second fixing component 116 drives the second lead screw 1165 to rotate, causing the sleeve 1161 to be sleeved on the central shaft 41 and close to the stepped surface 413 of the central shaft 41. 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.
