DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.

[0018] like Figure 1-2 As shown, the utility model provides a mobile polishing machine, including a polishing box 1, and the polishing box 1 has wire holes 2 symmetrically opened on both sides, and the wire holes 2 can be used for the wires to be polished to pass through. An adjusting screw 6 and a guide rod 8 are arranged in parallel in the polishing box 1, and the adjusting screw 6 is also provided with a first thread segment 601 and a second thread segment 602 with opposite rotation directions. A motor seat 3 is installed on each of the first thread segment 601 and the second thread segment 602, and the other side of the motor seat 3 is sleeved on the guide rod 8 through a second connecting block 9. A polishing motor 4 is also installed on the motor seat 3, and a first output shaft 401 is provided on the polishing motor 4. A polishing wheel 5 is sleeved on the first output shaft 401. The two polishing wheels 5 are symmetrically arranged relative to the central connecting line of the wire holes 2, and one end of the adjusting screw 6 extends out of the polishing box 1 and is connected to a hand wheel 12. When in use, by rotating the hand wheel 12, the adjusting screw 6 can drive the two first connecting blocks 7 to move toward each other along the adjusting screw 6, and the second connecting block 9 can slide synchronously on the guide rod 8, thereby driving the two motor seats 3 to move toward each other, so that the two polishing wheels 5 are close to each other until they touch the surface of the wire, and then polish and grind both sides of the wire, which is conducive to saving a lot of manpower and time costs and improving the efficiency of wire polishing. After polishing, the hand wheel 12 can be rotated in the opposite direction to make the two polishing wheels 5 move away from each other. The bottom of the polishing box 1 is also connected to a swing device 13, and one end of the swing device 13 is connected to a swing motor 14. The swing device 13 is driven by the swing motor 14 to move, so that the swing device 13 drives the polishing box 1 to reciprocate, so that the polishing wheel 5 can reciprocate while polishing the wire, thereby preventing the polishing wheel 5 from being locally concentratedly worn, so that the polishing wheel 5 is evenly worn, which is conducive to improving the use effect and service life of the polishing wheel 5.

[0019] Specifically, see Figure 1 and Figure 4The swing device 13 includes a support seat 1304, two tracks 1302 are arranged on the support seat 1304, and a track groove 1301 corresponding to the track 1302 is arranged at the bottom of the polishing box 1. The swing device 13 also includes a shell 1303, and the exterior of the shell 1303 is connected to the bottom of the polishing box 1 through a connecting piece 1307. The two opposite inner walls of the shell 1303 are symmetrically provided with a first rack 13031 and a second rack 13032. The swing motor 14 is provided with a second output shaft 1306, and a gear 1305 is sleeved on the second output shaft 1306. The gear 1305 includes a non-toothed portion 13052 and a toothed portion 13051 that can mesh with the first rack 13031 and the second rack 13032. The gear 1305 is driven to rotate by the swing motor 14. When the toothed part 13051 is engaged with the first rack 13031, the second rack 13032 corresponds to the non-toothed part 13052, so that the shell 1303 moves in a straight line; when the toothed part 13051 is engaged with the second rack 13032, the first rack 13031 corresponds to the non-toothed part 13052, so that the shell 1303 moves in a straight line in the opposite direction, thereby driving the rail groove 1301 to reciprocate along the rail 1302, driving the polishing box 1 to reciprocate.

[0020] Specifically, see Figure 1 One end of the adjusting screw rod 6 is connected to the bottom plate of the polishing box 1 through a rolling bearing 10, and the other end of the adjusting screw rod 6 is connected to the top plate of the polishing box 1 through a rolling bearing 10, and passes through the outside of the top plate of the polishing box 1 to be connected with a hand wheel 12. One end of the guide rod 8 is fixed to the bottom plate of the polishing box 1 through a fixed bearing 11, and the other end of the guide rod 8 is fixed to the top plate of the polishing box 1 through a fixed bearing 11. Preferably, the rolling bearing 10 is an outer spherical ball bearing with a rhombus seat, and the rhombus seat can increase the support area of ​​the rolling bearing 10, thereby improving the stability and load-bearing capacity of the rolling bearing 10.

[0021] Specifically, see Figure 2-3 The motor seat 3 is installed on the adjusting screw rod 6 through the first connecting block 7 and on the guide rod 8 through the second connecting block 9. The first connecting block 7 is provided with an internal threaded hole meshed with the first threaded segment 601 or the second threaded segment 602. The first threaded segment 601 and the second threaded segment 602 are respectively screwed into the internal threaded holes of the two first connecting blocks 7. The first threaded segment 601 and the second threaded segment 602 move toward each other, which can drive the first connecting block 7 to move accordingly. The second connecting block 9 is provided with a guide hole along the axis direction of the adjusting screw rod 6. The guide rod 8 passes through the guide hole with a clearance fit, providing sufficient space for the guide rod 8 to slide in the guide hole. The axis of the adjusting screw rod 6 and the guide rod 8 is perpendicular to the axis of the wire hole 2.

[0022] Specific implementation process: When in use, by rotating the hand wheel 12, the adjusting screw 6 drives the two motor seats 3 to move toward each other, so that the two polishing wheels 5 approach the wire passing through the wire hole 2, until the two polishing wheels 5 both contact the double sides of the wire, start the polishing motor 4 and the swing motor 14, so that the polishing wheel 5 reciprocates while polishing the wire, which can not only polish the double sides of the wire, but also help prevent local concentrated wear of the polishing wheel 5.
