DETAILED DESCRIPTION
[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0027] like Figure 1 and Figure 2 As shown, a wire-feeding device of a wire-cutting machine tool comprises a column frame 10, on the upper and lower front walls of the column frame 10 a guide wheel and a guide wheel seat 11 are fixedly mounted, on the front walls of the guide wheel and the guide wheel seat 11 a wire-feeding device for assisting the cutting wire is fixedly mounted, the wire-feeding device comprises a first limit plate 13 and a second limit plate 14.
[0028] It is worth noting that the column frame 10, the guide wheel and the guide wheel seat 11 have all been disclosed in a balanced wire-cutting device for a wire-cutting machine tool (201410470440.3), and will not be described in detail here.
[0029] During specific use, the wire-feeding device can assist the use of the cutting wire through the first limiting plate 13 and the second limiting plate 14, so that the cutting wire can be located at different positions to meet different work requirements.
[0030] In summary, by setting up a wire feeding device, the wire feeding device can assist the use of the cutting wire through the first limit plate 13 and the second limit plate 14, so that the cutting wire can be located at different positions to meet different work requirements. It is easy to use and has a simple structure.
[0031] like Figure 3 As shown, the first limit plate 13 is rotatably mounted on the front side wall of the guide wheel and the guide wheel seat 11, the second limit plate 14 is located in front of the first limit plate 13, and a threaded hole 19 is provided on the first limit plate 13 and the front side wall of the first limit plate 13, and a first bolt 18 is threadedly connected in the cavity of the two threaded holes 19.
[0032] A first limiting hole 16 is formed on the front wall of the first limiting plate 13 , a moving groove 15 is formed on the rear wall of the first limiting hole 16 , and a second limiting hole 17 is formed on the front wall of the second limiting plate 14 at a position corresponding to the first limiting hole 16 .
[0033] The wire feeding device further comprises two connecting columns 21 , between which a rotating column 22 is rotatably mounted, and a clamping plate 23 is fixedly mounted on the rear wall surface of the rear connecting column 21 , and the clamping plate 23 is clamped into the cavity of the moving groove 15 .
[0034] During specific use, the clamping plate 23 is inserted into the cavity of the movable groove 15 to limit the two connecting columns 21 and the rotating column 22 through the first limiting hole 16 and the second limiting plate 14. The connecting column 21 and the rotating column 22 can also be moved in the cavity of the first limiting hole 16 and the second limiting hole 17 through the movable groove 15. When the staff rotates the first bolt 18, the second limiting plate 14 can be moved closer to or away from the first limiting plate 13. The threaded hole 19 can limit the first bolt 18 to cope with cutting lines of different specifications. The first limiting plate 13 and the second limiting plate 14 are used to limit cutting lines of different specifications. The rotation of the rotating column 22 can reduce friction with the cutting line during operation and will not damage the cutting line.
[0035] To summarize, by setting the first limiting plate 13, the second limiting plate 14, the movable groove 15, the first limiting hole 16, the second limiting hole 17, the first bolt 18 and the threaded hole 19, the first limiting plate 13 and the second limiting plate 14 can be limited to cutting lines of different specifications by rotating the first bolt 18. It is easy to use and has a simple structure.
[0036] like Figure 3 , Figure 4 and Figure 5As shown, a sleeve plate 24 is fixedly installed on the front side wall of the second limiting plate 14 , the front side wall and the upper and lower side walls of the sleeve plate 24 are hollowed out, and a fixing block 25 is movably installed in the cavity of the sleeve plate 24 .
[0037] A second bolt 20 is disposed between the fixing block 25 and the front connecting column 21 , and the second bolt 20 fixes the fixing block 25 and the front connecting column 21 respectively.
[0038] The penetration point of the second bolt 20 and the fixing block 25 is a rotational connection, and the penetration point of the second bolt 20 and the front connecting column 21 is a threaded connection.
[0039] During specific use, when the staff rotates the fixed block 25, the front connecting column 21 can be driven to move, thereby driving the rotating column 22 to move through the limiting of the clamping plate 23, so as to change the position of the cutting line to meet different work requirements. The sleeve plate 24 can move when the second limiting plate 14 moves, and the fixed block 25 is limited by the sleeve plate 24, thereby limiting the connecting column 21. The staff can also rotate the first limiting plate 13 to change the position of the cutting line. The friction force of the rotational connection between the first limiting plate 13 and the guide wheel and the wall of the guide wheel seat 11 is relatively large, and it will not rotate easily, thereby stabilizing the operation of the cutting line.
[0040] In summary, by setting the sleeve plate 24, the second bolt 20, the fixing block 25, the connecting column 21 and the rotating column 22, the position of the cutting line can be changed by rotating the second bolt 20 to meet different work requirements. It is easy to use and has a simple structure.
