Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a bushing clamping mechanism for bushing continuous rotation wear test machine as shown in fig. 1-3, the on-line screen storage device comprises a base 1, mobile station 4, motor 7, lead screw 9 and slider 11, an open slot 101 has respectively been seted up to base 1's top both sides, base 1's top welding has support 2, guide rail 3 has all been welded to the both sides of support 2, two mobile station 4 cup joint respectively on guide rail 3, in order to ensure the direction relation between guide rail 3 and the mobile station 4 when the installation, spacing groove 31 has all been seted up in two guide rail 3's surface both sides, all be equipped with stopper 41 on two mobile station 4's the inner wall, stopper 41 and the laminating of spacing groove 31 on the mobile station 4, make overall structure more firm with this.

And the top of two mobile stations 4 all is equipped with arm lock 5, lay and bond at the surface of arm lock 5 and have the silica gel pad, can effectively improve surface friction, can avoid again causing certain wearing and tearing to the bushing surface because of motor 7 driven arm lock 5, in order to carry out the injecture of shift position to mobile station 4, end cover 6 has all been cup jointed at the end of two guide rails 3, with this avoid mobile station 4 roll-off guide rail 3 after the assembly, provide certain protecting effect to guide rail 3 simultaneously, avoid outside to collide with and influence the guide effect of guide rail 3.

The motor 7 is assembled in the base 1, in order to provide a certain protection effect, a fixed frame is assembled outside the motor 7, and meanwhile, the motor 7 can provide enough rotating force to enable the first bevel gear 8 to rotate; and the output of motor 7 passes through key and 8 key-type connections of first bevel gear, two lead screws 9 all assemble on base 1's inner wall through the bearing, and the one end of two lead screws 9 all passes through key and 10 key-type connections of second bevel gear, two second bevel gears 10 are connected with 8 transmission of first bevel gear respectively, two sliders 11 all set gradually on two lead screws 9 through thread groove 12, and the top of slider 11 passes the open slot and cooperates connecting piece and moving platform 4 fixed connection through connecting rod 13, be equipped with battery 14 in the base 1, the surface of base 1 is equipped with control button 15, and motor 7 passes through circuit cooperation control button 15 and battery 14 electric connection.
