Detailed Description
As shown in fig. 2-4, a fixture for fixing a guide disc lathe of a rolling mill comprises a base 1, wherein a fixed seat 2 is fixed at the top of the base 1, a limit groove 21 is formed in the fixed seat 2, and the fixed seat 2 is used for supporting a guide disc; the limiting plate 3 and the limiting plate fixing device 4 are arranged on the fixing seat 2, so that the limiting plate 3, the limiting plate fixing device 4 and the limiting groove 21 can be matched with the clamping adjusting block 6 to clamp and fix the guide disc; the front of the fixed seat 2 is provided with a fastening bracket 5.
As shown in fig. 3, the limiting plate fixing device 4 includes a nut 41, a bolt 42, and an internally threaded tube 43; one end of the internal thread pipe 43 is fixed on the fixed seat 2, the other end is internally provided with threads, the internal thread pipe is in threaded fit connection with the bolt 42, the external thread of the bolt 42 is connected with the nut 41, and the limiting plate 3 is positioned below the nut 41; one end of the lower surface of the limiting plate 3 is contacted with the fixed seat 2, the other end is contacted with the upper surface of the adjusting block, and the limiting plate 3 can be fixed by screwing the bolt 42 and the nut 41.
One end of the internal thread pipe 43 is welded on the fixed seat 2, a reinforcing rib 44 is arranged below the internal thread pipe 43, the inclined internal thread pipe 43 is supported, the bonding strength of the internal thread pipe 43 and the fixed seat 2 is improved, and the service life is prolonged.
As shown in fig. 4, the limiting plate 3 is provided with a bar-shaped hole 31, the width of the bar-shaped hole 31 is larger than the outer diameter of the internal thread tube 43 and smaller than the outer diameter of the nut 41, so that the limiting plate 3 can move outside the bolt 42 and the internal thread tube 43, and the position and angle of the limiting plate 3 can be adjusted, so that the limiting plate 3 is better matched with the adjusting block 6.
