[0050] like Figures 1 to 14 As shown, based on Example 1, a motor assembly line for an electric vehicle further includes:
[0051] The discharging mechanism includes a feeding box 50, a discharging pipe 51, a discharging frame 52 and an eighth hydraulic cylinder 53. The feeding box 50 is mounted on the lifting platform 42, the discharging pipe 51 is mounted on the feeding box 50, and the discharging pipe 51 is located above the hexagonal wrench 45, the discharging frame 52 is slidably mounted on the feeding box 50, the eighth hydraulic cylinder 53 is fixedly mounted on the feeding box 50, and one end of the eighth hydraulic cylinder 53 is mounted on the discharging frame 52;
[0052] The stator is wound by the stator winding machine 58, and the permanent magnet is placed on the supporting mold 4. The driving motor in the workbench 1 drives the supporting table 2 to rotate, and the permanent magnet is moved to the bottom of the thermal induction heater 6. The first hydraulic cylinder 3 is extended to extend the permanent magnet into the thermal induction heater 6, so that the thermal induction heater 6 heats the permanent magnet to the required temperature. The first hydraulic cylinder 3 is then contracted to reset the supporting mold 4. At the same time, the output shaft with the end cover is clamped by the clamp 8. The supporting table 2 is rotated to transport the heated permanent magnet to the bottom of the clamp 8. The second hydraulic cylinder 7 is extended to allow the clamp 8 to insert the output shaft with the end cover into the middle of the permanent magnet. After the permanent magnet cools down, an interference fit is formed between the permanent magnet and the output shaft with the end cover. The shell is placed on the limiting mold 11, and the limiting mold 11 is used to limit the shell. Then, the plate conveyor 10 is used to transport the shell from left to right, and the dry ice is placed in the crushing box 16. The first motor 19 is turned on to make the scraper 20 crush the dry ice. At the same time, the air intake of the exhaust pump 18 is connected to the air compression device, and the exhaust pump 18 is turned on to discharge the compressed air into the crushing box 16, so that the compressed air is mixed with the crushed dry ice to form a mixture, and the shielding box 14 is covered on the plate conveyor 10 through the third hydraulic cylinder 15, and the jet pipe 23 is extended into the shell. After that, the mixture passes through the first telescopic tube 21 and the rotary joint 22 in sequence, so that the mixture enters the jet pipe 23, and then the second motor 24 is turned on, and the mixture is connected to the gear 25 and the The gear ring 26 is meshed and driven to drive the jet pipe 23 to rotate, and then the mixture is sprayed out through the multiple groups of nozzles 27 to clean the dust and oil in the shell, and then the electric control valve 32 is opened to pour the adhesive into the glue storage cylinder 29, so that the adhesive passes through the electric control valve 32 and flows to the bottom of the glue storage cylinder 29, and then the electric control valve 32 is closed, and the fifth hydraulic cylinder 33 is extended to adjust the height of the spray gun 35, and then the fourth hydraulic cylinder 30 is extended to make the piston 31 slide downward, pressurize the inside of the glue storage cylinder 29, so that the adhesive passes through the second telescopic tube 39 and enters the spray gun 35, and then the spray gun 35 is opened, and the third motor 37 is turned on at the same time, and the bevel gear 38 is meshed and driven with the bevel gear ring 36 to rotate the spray gun 35, and the adhesive is sprayed through the spray gun 35 The discharging rack 52 is pulled out of the loading box 50 by the extension of the eighth hydraulic cylinder 53, and then multiple groups of hexagonal bolts are neatly placed with their big heads downward into the loading box 50, and the discharging rack 52 is reinserted into the loading box 50 by the contraction of the eighth hydraulic cylinder 53, and as the eighth hydraulic cylinder 53 continues to contract, the hexagonal bolts are fed into the discharging pipe 51, and the assembled motor is placed on the lifting platform 42, and the two groups of seventh hydraulic cylinders 47 are extended to clamp the assembled motor with two groups of clamping plates 48.Then connect the assembled motor to the power supply, slide the electric slider 46 backward, push the output shaft of the assembled motor against the spline sleeve 56, and shrink the spring 57 and the telescopic rod 55, and run the assembled motor to rotate the output shaft of the assembled motor, so that the output shaft of the assembled motor is aligned with the spline sleeve 56, and then the spline sleeve 56 is sleeved on the output shaft of the assembled motor through the elasticity of the spring 57, and then run the assembled motor, and the assembled motor continues to run, through the transmission of the reduction box 44, so that the multiple sets of hexagonal wrenches 45 rotate, and at the same time, the multiple sets of hexagonal bolts are transported one by one through the multiple sets of discharge mechanisms, and the sixth hydraulic cylinder 43 is extended to move the electric control valve 32 upward, and the multiple sets of hexagonal wrenches 45 are respectively inserted into the multiple sets of discharge pipes 51, and then the sixth hydraulic cylinder 43 continues to extend, so that the multiple sets of hexagonal wrenches 45 can tighten the hexagonal bolts in the multiple sets of discharge pipes 51. The sixth hydraulic cylinder 43 is pushed out, and the multiple sets of hexagonal wrenches 45 are respectively extended to make the multiple sets of perforations on the limit mold 11, and the hexagonal bolts are passed through the shell by rotating the multiple sets of hexagonal wrenches 45, and the hexagonal bolts are threadedly installed on the end cover, so that the shell and the end cover are sealed to the stator and the rotor, and the motor packaging is completed. In the operation process of the assembled motor, the speed sensor 49 is used to detect the speed of the motor output shaft. The staff judges the operating status of the assembled motor through the detection results of the speed sensor 49 and the rotation status of the multiple sets of hexagonal wrenches 45. When the equipment is shut down and restarted, the heating elements in the glue storage barrel 29 and the piston 31 are turned on. After the top adhesive is melted, the fourth hydraulic cylinder 30 continues to extend, so that the piston 31 moves downward to continuously heat the solidified adhesive, so that the adhesive in the glue storage barrel 29 quickly reaches a flowing state, thereby improving the practicality of the equipment.
[0053] In actual application, other processing equipment or workstations can be added based on this assembly line.
[0054] The main functions achieved by the present invention are: improving detection convenience and production efficiency, improving cleaning effect, and increasing the melting speed of the adhesive;
[0055] 1. Improve detection convenience and production efficiency: The assembly mechanism uses the assembled motor as the power source to assemble and seal the motor in the assembly process, and completes the detection of the operating status of the assembled motor during the sealing process, thereby improving detection convenience and production efficiency;
