By adopting the above technical scheme, after the wheel shell 102, the shaft 103 and the shaft cover 104 are cleaned, the double-speed chain conveyor 1 is started and transferred to the drying mechanism 3, and then the fan is started to dry the water stains on the surface of the parts through the shaft drying head 302, the shaft cover drying head 303 and the wheel shell drying head 304.

[0119] In this embodiment, the first copper sleeve pressing assembly includes a first feeding mechanism 401 and a first copper sleeve pressing mechanism 501, the first feeding mechanism 401 is used to provide the copper sleeve to the first copper sleeve pressing mechanism 501, and the second copper sleeve pressing assembly includes a second feeding mechanism 402 and a second copper sleeve pressing mechanism 502, the second feeding mechanism 402 is used to provide the copper sleeve to the second copper sleeve pressing mechanism 502;

[0120] The first copper sleeve pressing mechanism 501 and the second copper sleeve pressing mechanism 502 have the same structure. The first copper sleeve pressing mechanism 501 and the second copper sleeve pressing mechanism 502 both include a first frame 5001. A fifth cylinder 5002 is fixedly installed at the lower end of the first frame 5001. The top of the piston rod of the fifth cylinder 5002 is fixedly connected to a first lifting seat 5003. The top of the first lifting seat 5003 can be against the bottom of the bearing plate 101 to support the bearing plate 101. The first frame The upper end of 5001 is fixedly installed with a sixth cylinder 5004, the lower end of the piston rod of the sixth cylinder 5004 is fixedly installed with a second lifting seat 5005, the bottom of the piston rod of the sixth cylinder 5004 is fixedly connected with a press-in block 5006, the inner side of the first frame 5001 is fixedly installed with a third mounting seat 5007, the middle part of the third mounting seat 5007 is provided with a through hole, and the third mounting seat 5007 is located on both sides of the through hole and is fixedly connected with a second slide rail 5012, and the second slide rail 5012 A clamping seat 5013 is installed on the upper sliding, and grooves 5008 are opened on both sides of the third mounting seat 5007 on the through hole. A first spring 5009 is arranged inside the groove 5008. The bottom of the clamping seat 5013 is fixedly connected with an extrusion block, and the lower end of the extrusion block extends into the groove 5008. One end of the first spring 5009 abuts against one side of the extrusion block, and the other end of the first spring 5009 abuts against the end of the groove 5008 away from the through hole. The bottom of the second lifting seat 5005 is fixedly connected to A shift rod 5011 is connected, and a shift block 5010 is fixedly connected to the clamping seat 5013. When the shift rod 5011 moves downward, it can squeeze the shift block 5010, so that the clamping seat 5013 moves away from the through hole, and then the clamping seat 5013 releases the clamping of the copper sleeve. When the shift rod 5011 moves upward, the shift rod 5011 releases the squeezing of the shift block 5010, and the clamping seat 5013 is reset to a direction close to the through hole under the elastic force of the first spring 5009.

[0121] By adopting the first copper sleeve pressing mechanism 501 and the second copper sleeve pressing mechanism 502 of the above technical solution, when in use, when the wheel housing 102 has been sent to the bottom of the pressing block 5006, the double-speed chain conveyor 1 stops, and then the piston rod of the sixth cylinder 5004 and the piston rod of the fifth cylinder 5002 are controlled to extend, so that the bottom of the first lifting seat 5003 is against the bottom of the supporting plate 101 to support the supporting plate 101. As the piston rod of the sixth cylinder 5004 continues to extend, the lever 5011 continues to move downward, so that the lever 5011 squeezes the shifting block 5010, so that the clamping seat 5013 moves upward. The first lifting seat 5003 is then controlled to move downward in a direction away from the through hole, thereby releasing the clamping of the copper sleeve, allowing the copper sleeve to fall into the wheel housing 102 through the through hole. At the same time, the copper sleeve is pressed into the wheel housing 102 by the pressing block 5006. The piston rod of the sixth cylinder 5004 is then controlled to reset upward. When the lever 5011 moves upward, the lever 5011 releases the squeezing of the shift block 5010. At this time, the clamping seat 5013 is reset toward the through hole under the elastic force of the first spring 5009. The piston rod of the fifth cylinder 5002 is then controlled to retract and reset, thereby causing the first lifting seat 5003 to move downward, thereby releasing the limit on the supporting plate 101.
