Currently, the end face processing of center muntin profiles is mainly carried out by CNC end milling machines. However, since most of the existing CNC end milling machines use a single saw blade for milling, it is difficult to process multiple grooves with different widths. When processing, multiple milling operations are required, and one-time milling cannot be achieved. At the same time, the end face of the muntin profile also needs to be cut off. During the cutting process, the cutter used cannot be used universally with the milling cutter used for milling grooves. This results in the cutting process needing to be performed on cutting equipment, and the profile If the equipment is replaced for processing, it will easily affect the processing accuracy of the profile.

Furthermore, for existing CNC end milling machines, most of the profile loading operations are performed manually, and manual alignment of the profiles is required, which undoubtedly affects efficiency when performing large-volume processing operations. Phenomenon, and for most CNC end milling machines, when processing the center mullion profile, only one end face can be processed, and the other end face needs to be manually replaced when processing.

The sliding stroke of the left sliding seat 3 and the right sliding seat 4 here is the Z-axis stroke of the machine tool, and the left sliding seat 3 and the right sliding seat 4 Both the base 3 and the right sliding base 4 can independently move the Z-axis. The left sliding base 3 and the right sliding base 4 are provided with a left travel platform 5 and a right travel platform 6 sliding in the horizontal direction. Here the left travel The sliding stroke of the table 5 and the right stroke table 6 is the X-axis stroke of the machine tool, and the left stroke table 5 and the right stroke table 6 can both move in the X axis independently. The upper edges of the left stroke table 5 and the right stroke table 6 are vertical A milling mechanism 7 and a milling mechanism 8 are provided in the straight direction, and the left travel stage 5 is provided with a rotating assembly 9 that drives the milling mechanism 7 to rotate.

As shown in Figure 2 or 6, the milling mechanism 7 includes a first spindle motor 701, a first milling saw blade 702, a cutter saw blade 703, and a connecting shaft 704. What needs to be explained here is the first spindle motor. 701, and the second spindle motor 801 described below are all dual-axis motors, with rotating shafts at both ends of the motor. The rotating assembly 9 includes a pushing cylinder 901. The cylinder body of the pushing cylinder 901 is hinged on the left traveling platform. The connecting shaft 704 is horizontal and perpendicular to the left traveling platform 5, and one end of the connecting shaft 704 passes through the left traveling platform 5. Connected to the piston rod of the pushing cylinder 901, the left stroke platform 5 here is provided with a through hole that matches the connecting shaft 704.

It should be noted that when the milling cutter is in use, the milling cutter saw blade should be kept in a horizontal state, and when the cutter is in use, the cutter saw blade 703 should be kept in a vertical state. Therefore, when using a cutter, the first spindle motor 701 is rotated 90° by pushing the cylinder 901 to a horizontal state. When using a milling cutter, the pushing cylinder 901 does not move and the first spindle motor 701 is in a vertical state.

The travel table 6 is fixedly connected, and the second milling cutter blade 802 and the third milling cutter blade 803 are respectively connected to the output shafts at the upper and lower ends of the second spindle motor 801. It is stated here that the first milling cutter blade 702 and the second milling cutter blade 802 and the third milling cutter blade 803 here can be installed with milling cutter blades of different thicknesses.

When the milling mechanism 7 and the milling mechanism 8 are working, the above-mentioned left sliding seat 3 and right sliding seat 4 can cause a height difference between the two, thereby achieving the effect of cutting grooves at different positions on the profile end surface. , at the same time, after the milling mechanism 7 and the milling mechanism 8 complete the first cutting stroke, when returning to cutting for the second time, the height can be adjusted again, and then the cutting of grooves at different positions can be completed, and the groove can also be adjusted. The depth of cutting enables one reciprocating motion of the milling mechanism 7 and the milling mechanism 8 to complete groove cutting at four different positions on the profile end face, which is sufficient to meet the processing needs of the end faces of most profiles, and by installing saws of different thicknesses The blade realizes cutting of grooves of different widths, achieving one-time processing, and finally the first spindle motor 701 on the milling mechanism 7 can be rotated by pushing the cylinder 901, thereby enabling the cutter saw blade 703 to cut the profile end face Carry out section processing.

S2, arrange the profiles to be cut neatly on the transmission belt of the conveyor platform 13, and start the conveyor belt 17 to rotate forward so that the profiles move forward;

S3, the profile moves to the rotating platform 14, and the conveyor belt 17 on the rotating platform 14 also rotates forward, so that the profile moves to the fixed material processing platform 16, and the conveyor belt 17 on the fixed material processing platform 16 rotates forward, so that the profile passes through the end positioning plate 16021 for alignment, and at the same time, the side drive cylinder 16032 on the fixed material processing platform 16 moves to push the side positioning plate 16031 to position the side of the profile;

What needs to be noted here is that when the profile moves to the rotating platform 14, the conveyor belt 17 on the feeding platform 13 will stop rotating.

S4, after the end face and side positioning is completed, the conveyor belt 17 on the rotating platform 14 and the conveyor belt 17 on the fixed material processing platform 16 stop rotating, and the end face driving cylinder 16022 retracts the end face positioning plate 16021, so that the end face positioning plate 16021 is positioned entirely on the support table 1601 At the lower end position, the side drive cylinder 16032 retracts the side positioning plate 16031 and returns to the initial position;
