[0039] The second method is to install the angle milling head 53 and the dust cover 45 at the same time. First, the first cylinder 2 pushes the dust cover mold assembly 4 to move toward the first sensing switch 13. After moving into position, the first sensing switch 13 transmits the in-position signal to the PLC control system. After receiving the signal, the PLC control system controls the spindle box to move above the dust cover mold assembly 4 and places the dust cover 45 on the spindle box on the dust cover base 41 through the hydraulic system on the spindle box; the fifth sensing switch 42 senses that the dust cover 45 is in place and transmits the signal to the PLC control system. After receiving the signal, the PLC control system controls the first cylinder 2 to retract the dust cover mold assembly 4; the second sensing switch 14 senses that the dust cover mold assembly 4 is retracted into position and transmits the signal to the PLC control system.

After receiving the signal, the PLC control system controls the first cylinder 2 to retract the dust cover mold assembly 4.

[0040] Therefore, both working modes in this case can be completed by machines throughout the process without human intervention, with a high degree of automation, greatly improving the exchange efficiency.

[0041] As a specific installation method of the dust cover 45 and the angle milling head 53, preferably, the dust cover mold assembly 4 also includes two dust cover support plates 44 arranged opposite to each other, the fifth induction switch 42 is arranged on the dust cover support plate 44, the angle milling head mold assembly 5 also includes two angle milling head support plates 54 arranged opposite to each other, the sixth induction switch 52 is arranged on the angle milling head support plate 54, and a buffer structure is provided between the dust cover base 41 and the dust cover support plate 44 and between the angle milling head base 51 and the angle milling head support plate 54. The buffer structure includes a spring 61, a guide column 62 and a guide sleeve 63, the guide sleeve 63 is fixed on the dust cover base 41 or the angle milling head base 51, the guide column 62 passes through the guide sleeve 63 and is movably matched with the dust cover base 41 or the angle milling head base 51, that is, the guide column 62 is fixedly connected to the guide sleeve 63. The spring 61 is sleeved on the guide column 62 between the dust cover base 41 and the dust cover support plate or between the angle milling head base 51 and the angle milling head support plate 54. Each support plate is equipped with four buffer structures to provide pressure buffering for the four corners of the base. In this way, the dust cover support plate 44 or the angle milling head support plate 54 will move up and down along the guide column 62, and the spring 61 can buffer the pressure of the dust cover 45 or the angle milling head 53 to reduce the impact.

[0042] Preferably, the dust cover mold assembly 4 and the angle milling head mold assembly 5 also include an adjustment positioning structure, specifically, two adjustment positioning structures are provided at both ends of each support plate. The adjustment positioning structure includes a positioning pin 71, a positioning block 72 and an adjusting screw 73, the positioning block 72 is fixed on the dust cover support plate 44 or the angle milling head support plate 54, the positioning pin 71 is locked on the positioning block 72, the dust cover 45 and the angle milling head 53 are placed on the positioning pin 71, and the dust cover 45 and the dust cover support plate 44 or the angle milling head 53 and the angle milling head support plate 54 are adjusted by the adjusting screw 73. In this way, the dust cover 45 or the angle milling head is mainly supported and fixed by the positioning pin 71, and the adjusting screw 73 is used to assist in leveling, so that the dust cover 45 or the angle milling head 53 is placed flat.

[0043] Preferably, one end of the first linear rail 11 and the second linear rail 12 is further provided with a limit block 16, and the limit block 16 can prevent the two bases from moving out of the linear rail.

[0044] Preferably, it further comprises a first floating joint bracket 17 connected to the dust cover base 41 and a second floating joint bracket 18 connected to the angle milling head base 51, the piston rod of the first cylinder 2 is connected to the first floating joint bracket 17, and the piston rod of the second cylinder 3 is connected to the second floating joint bracket 18. The cylinder drives the base to move by driving the floating joint bracket.

[0045] When the second working mode is performed in this case, the components may move in disorder. In order to reduce the error rate, preferably, as another specific embodiment of this case, this case also includes a third cylinder 81 and a limit column 82. The third cylinder 81 is fixed on the second floating joint bracket 18 and one end of the piston rod of the third cylinder 81 is connected to the limit column 82. The bottom surface of the first floating joint bracket 17 is provided with a limit hole corresponding to the limit column 82. The third cylinder 81 can drive the limit column 82 to enter the limit hole. In this way, the specific operation of this embodiment when the second working mode is performed is as follows:

[0046] The first cylinder 2 and the second cylinder 3 simultaneously move the dust cover mold assembly 4 and the angle milling head mold assembly 5 toward the first sensing switch 13 and the third sensing switch 15. At this time, the limiting column 82 is inserted into the limiting hole, so that the dust cover mold assembly 4 and the angle milling head mold assembly 5 can be linked, thereby ensuring that the dust cover mold assembly 4 is on the angle milling head mold assembly 5. After the first sensing switch 13 and the third sensing switch 15 sense that the two components are in place, they transmit the in-place signal to the PLC control system. After receiving the signal, the PLC control system controls the spindle box to move above the dust cover mold assembly 4, and places the dust cover 45 on the spindle box on the dust cover base 41 through the hydraulic system on the spindle box. The fifth sensing switch After the switch 42 senses that the dust cover 45 is in place, it transmits a signal to the PLC control system. After receiving the signal, the PLC control system controls the third cylinder 81 to move the limit column 82 downward to separate from the limit hole, and at the same time, the first cylinder 2 retracts the dust cover mold assembly 4. At this time, the limit column 82 is separated from the limit hole to ensure that the two components move separately. After the second induction switch 14 senses that the dust cover mold assembly 4 is retracted into place, it transmits a signal to the PLC control system. After receiving the signal, the PLC control system controls the spindle box to move above the angle milling head mold assembly 5 and fixes the angle milling head 53 to the spindle box through the hydraulic system on the spindle box. The subsequent actions are the same as those in the first embodiment, which will not be repeated here. The biggest difference of this embodiment is that the third cylinder 81 and the limit column 82 are designed, so that the linkage of the two components can be ensured in the initial action, so that even if only the angle milling head mold assembly 5 is driven first by accident, the dust cover mold assembly 4 can be driven to move by linkage, which effectively avoids the accident of only moving the angle milling head mold assembly 5 in the initial stage of work, ensures that subsequent actions proceed smoothly, and greatly improves safety and success rate.
