Detailed Description
A clearance adjusting structure between a main shaft and copper shoes of a press comprises a main shaft 6, wherein the outer surface of the main shaft 6 floats in a main shaft hole of a machine body 1 through a plurality of copper shoes 5 and rolling bearings 3;
the rolling bearing 3 is fixed on the machine body 1 through a bearing seat 2, and the rolling bearing is arranged in the bearing seat 2;
an adjusting wedge block 4 is arranged on the step of the machine body, the adjusting wedge block 4 is positioned on the outer side of the bearing seat 1, and the adjusting wedge block 4 and the bearing seat 2 form conical surface fit.
Further, the bearing seat 1 is fixed on the machine body 1 through a screw.
Further, the adjusting wedge-shaped block 4 and the limiting block 7 are arranged on the outer side of the bearing seat 1, and the limiting block 7 is fixed on the machine body 1 to limit the bearing seat 2.
Further, the adjusting wedge block 4 is fixed on the machine body 1 through a screw, a countersunk hole and a threaded hole are formed in the adjusting wedge block 4, and the countersunk screw is installed at the countersunk hole and used for fixing the adjusting wedge block 4 on the machine body 1; and a full-thread screw and a hexagon nut are arranged at the threaded hole.
The following is a further explanation of the present invention to better understand the present invention: the utility model discloses main shaft 6 floats in 1 main shaft hole of fuselage through four brasses 5, two antifriction bearing 3, and main shaft 6 all has the clearance in order to make things convenient for the main shaft rotation with four brasses 5 contact department on the full circumferencial direction.
The utility model discloses two bearing frames 2 utilize the fix with screw on fuselage 1, need not the lock before doing the adjustment and die.
The utility model discloses two antifriction bearings 3 are installed respectively in the bearing frame 2 of the left and right sides.
The utility model discloses on the adjustment wedge 4 of the left and right sides utilized the fix with screw fuselage 1, need not the lock before doing the adjustment and dies, can do the linear motion displacement of screw axis direction.
The utility model discloses 2 outsides of bearing frame are three stoppers 7 of 90 distribution installation and adjustment wedge 4.
The utility model discloses three stopper 7 utilize the fix with screw in fuselage 1 on, need not the lock before doing the adjustment and die, are used for restricting the displacement that bearing frame 2 probably produced in all directions after the adjustment is ended.
The utility model designs the screw hole of the adjusting wedge block 4 into two forms of a countersunk hole and a threaded hole, and the countersunk screw is arranged at the countersunk hole and is used for fixing the adjusting wedge block 4 on the machine body 1, but the countersunk screw is not completely locked at the moment; and a full-thread screw and a hexagon nut are arranged at the threaded hole.
The utility model discloses when the clearance between adjustment main shaft and brasses, we make adjustment wedge 4 be inside or outside displacement motion along the axis direction of full thread screw through spanner rotating hexagon nut. When the wedge-shaped block 4 is adjusted to move inwards, the bearing seat 2 floats upwards and drives the crankshaft to float upwards; when the wedge-shaped block 4 is adjusted to move outwards, the bearing seat 2 sinks downwards and drives the crankshaft to move downwards, so that the purpose of adjusting the gap values A and B of the copper tiles at four positions in the drawing 1 is achieved. After the clearance value required by design is obtained, the bearing seat 2, the adjusting wedge-shaped block 4 and the limiting block 7 are locked through screws.
