[0021] It should be noted that this application uses the existing structure of a gantry milling machine tool 1, milling head 2, and spray cooling pipe 3, which is a common structure in milling. In this application, to achieve batch milling of the cathode plate beam 13, the number of milling heads 2 has been increased, but this is also prior art. Therefore, the gantry milling machine tool 1, milling head 2, spray cooling pipe 3, and the corresponding CNC system controlling the gantry milling machine tool 1, as well as the frequency converter 11 connected to each group of milling heads 2, all adopt existing structures. The frequency converter 11 is matched with the spindle motor, and the milling rotation is adjusted in real time through the CNC system. This application does not elaborate on its specific components. Improvements were made to the internal structure and control mechanism. Improvements were made only to the fixing and positioning of the cathode plate beam 13, which is rectangular in shape in the initial state. After the cathode plate beam 13 is fixed on the support chassis 4, the milling head 2 on the gantry milling machine tool 1 is controlled by the CNC system to rotate and move along the transverse milling groove 5 and the lug groove 6, thereby realizing the milling of the rectangular cathode plate beam 13. The cathode plate beam 13 and the lug can be integrated for machining. By setting multiple sets of transverse milling grooves 5 and lug grooves 6, multiple sets of cathode plate beams 13 can be fixed at the same time for synchronous milling operations, thereby improving the finished product quality of the cathode plate beam 13.

[0022] Further, see Figure 2 The shape of the ear groove 6 is consistent with the shape of the ear on the cathode plate beam 13. The bottom end of the ear groove 6 is lower than the top end of the supporting base plate, thus forming a support part 8 inside the ear groove 6.

[0023] Preferably, the support base 4 is a rectangular plate structure made of high-strength cast iron. The transverse milling groove 5 is a recessed straight groove opened on the support base 4. Since the lugs on the cathode plate beam 13 are similar to an "L" shape, the shape of the lug groove 6 is also similar to an "L" shape. Furthermore, there are two sets of relatively symmetrical lugs on a set of cathode plate beams 13. Therefore, there are also two sets of lug grooves 6 at the upper end of a set of transverse milling grooves 5. The lug groove 6 is also a recessed groove opened on the support base 4. After the lug groove 6 is opened, the part of the original support base 4 that was not cut and surrounded by the lug groove 6 forms the support part 8.

[0024] Further, see Figure 2 The fixing member 7 includes a fixing suction cup 701, the top of the fixing suction cup 701 and the top of the support part 8 are located on the same horizontal plane.

[0025] Preferably, the support base 4 is provided with mounting slots 12 on both sides of the transverse milling groove 5. The fixed suction cup 701 is installed in the mounting slot 12. The fixed suction cup 701 is a vacuum negative pressure suction cup. The vacuum negative pressure suction cup is provided with a negative pressure pipe 702, which is connected to an external vacuum negative pressure pump.

[0026] Preferably, the fixed suction disc 701 is arranged in multiple groups in sections, three groups of fixed suction discs 701 are arranged on one side of the ear hanging groove 6, two groups of which are arranged on one side of the two groups of ear hanging grooves 6, and the other group of fixed suction discs 701 is arranged between the two groups of ear hanging grooves 6; three groups of fixed suction discs 701 are arranged at intervals at the lower end of the transverse milling groove 5 (and on the opposite side of the ear hanging groove 6).

[0027] In the above arrangement, since the cathode plate cross beam 13 is in a long strip structure and is provided with two groups of ears, in the milling process, the cathode plate cross beam 13 is fixed on the support base plate 4 after vacuumizing by the fixed suction disc 701, and the milling head 2 moves along the transverse milling groove 5 and the ear hanging groove 6, so that the cathode plate cross beam 13 can be milled integrally, the transverse milling groove 5 and the ear hanging groove 6 provide space for the movement of the milling head 2, avoiding the contact between the milling head 2 and the support base plate 4, realizing the process of integrated machining and milling, and the oil liquid is sprayed out by the spray cooling pipe 3 for cooling and can remove the milling debris; the fixed suction disc 701 arranged in sections fixes the cathode plate cross beam 13 on the support base plate 4, which can avoid the deformation of the cathode plate cross beam 13 in the machining process, so that the flatness error is ≤0.1mm / m.

[0028] Further, referring to Figure 2 , the transverse positioning member 9 includes a transverse positioning frame 901 and a transverse positioning block 902 arranged on the transverse positioning frame 901, the end of the transverse positioning block 902 exceeds the end of the transverse positioning frame 901, and the extension line of the transverse milling groove 5 is perpendicular to the transverse positioning frame 901 and there is a spacing between the side end of the transverse positioning block 902.

[0029] Preferably, the transverse positioning frame 901 and the transverse positioning block 902 are made of high-strength cast iron material.

[0030] Preferably, the length of the support base plate 4 (the length in the direction from left to right) and the distance between the side end of the support base plate and the transverse positioning block 902 are equal to the length of the cathode plate cross beam 13, that is, after the cathode plate cross beam 13 is placed on the support base plate 4, the right end of the cathode plate cross beam 13 abuts against the transverse positioning block 902, and the lengths of the two ends of the cathode plate cross beam 13 exceeding the support base plate 4 are equal, so as to fix the position of the cathode plate cross beam 13 in the transverse direction by the transverse positioning block 902.

[0031] Further, referring to Figure 2 , the longitudinal positioning member 10 includes a longitudinal positioning column 1001 arranged at intervals on the support base plate 4.

[0032] Preferably, the longitudinal positioning column 1001 is located on the same straight line as the top end of the ear hanging groove 6.

[0033] In the above arrangement, when milling the cathode plate beam 13, the size after milling and the position of the lug on the cathode plate beam 13 need to meet the requirements. The distance between the two groups of lug grooves 6 is controlled, so that the distance between the two groups of lugs after milling can be controlled. The distance between the side end of the support base 4 and the transverse positioning block 902 is controlled, so that the distance from the lug groove 6 to the transverse positioning block 902 can be determined, so that the distance from the lug to the end of the cathode plate beam 13 after milling can be controlled to ensure that the cathode plate beam 13 after milling meets the requirements. The distance between the longitudinal positioning column 1001 and the transverse milling groove 5 is controlled to be consistent with the distance from the top end of the lug groove 6 to the transverse milling groove 5, so that the size of the cathode plate beam 13 body connected with the lug after milling meets the requirements. The cathode plate beam 13 to be processed is placed on the support base 4, and the right end of the cathode plate beam 13 abuts against the transverse positioning block 902 to determine the position of the cathode plate beam 13 in the transverse direction. Then the cathode plate beam 13 is moved to abut against the longitudinal positioning column 1001 to determine the position of the cathode plate beam 13 in the longitudinal direction. The cathode plate beam 13 to be processed is fixed on the support base 4 by the fixed suction cup 701, so as to ensure the processing precision.

[0034] In the above arrangement, when milling the cathode plate beam 13, the size after milling and the position of the lug on the cathode plate beam 13 need to meet the requirements. The distance between the two groups of lug grooves 6 is controlled, so that the distance between the two groups of lugs after milling can be controlled. The distance between the side end of the support base 4 and the transverse positioning block 902 is controlled, so that the distance from the lug groove 6 to the transverse positioning block 902 can be determined, so that the distance from the lug to the end of the cathode plate beam 13 after milling can be controlled to ensure that the cathode plate beam 13 after milling meets the requirements. The distance between the longitudinal positioning column 1001 and the transverse milling groove 5 is controlled to be consistent with the distance from the top end of the lug groove 6 to the transverse milling groove 5, so that the size of the cathode plate beam 13 body connected with the lug after milling meets the requirements. The cathode plate beam 13 to be processed is placed on the support base 4, and the right end of the cathode plate beam 13 abuts against the transverse positioning block 902 to determine the position of the cathode plate beam 13 in the transverse direction. Then the cathode plate beam 13 is moved to abut against the longitudinal positioning column 1001 to determine the position of the cathode plate beam 13 in the longitudinal direction. The cathode plate beam 13 to be processed is fixed on the support base 4 by the fixed suction cup 701, so as to ensure the processing precision.

[0035] Of course, in order to realize batch milling processing of the cathode plate cross beam 13, a plurality of groups of transverse milling grooves 5 and lug grooves 6 are arranged along the longitudinal direction of the support base 4, and transverse positioning blocks 902 and longitudinal positioning columns 1001 are arranged synchronously, each group of cathode plate cross beams 13 is positioned, and the milling head 2, the spray cooling pipe 3 and the frequency converter 11 are arranged correspondingly, so that a plurality of groups of cathode plate cross beams 13 can be milled at the same time, batch processing is realized, and the efficiency is improved.
