The invention provides a lining press-fitting device for installing a first lining and / or second lining in a containing hole of a brake lifting socket. The lining press-fitting device comprises a supporting rod group, a stop plate and a press moving assembly. At least part of the supporting rod group is used for penetrating into the containing hole. The stop plate is arranged on the supporting rodgroup and used for stopping the first lining. The press moving assembly is arranged on the supporting rod group and used for stopping the second lining. The press moving assembly is spaced from the stop plate so that the brake lifting socket can be clamped between the press moving assembly and the stop plate after at least part of the supporting rod group penetrates through the containing hole. The press moving assembly is movably connected with the supporting rod group, so that the stop plate and the press moving assembly get close to each other to rapidly and accurately extrude the first lining and / or the second lining into the containing hole when the press moving assembly moves in the direction close to the brake lifting socket, and the assembling efficiency of the first lining and / orthe second lining and the brake lifting socket is effectively improved.
Description
technical field [0001] The invention relates to the field of vehicle assembly, in particular to a bush pressing device. Background technique [0002] The bushing of the brake hanger of the standard EMU is made of nylon material. During the original installation, a nylon hammer was used to knock it into the hole of the brake hanger of the frame, or it was pressed into the hole of the brake hanger of the frame with self-made tooling. [0003] When installing, use a nylon hammer to knock the bushing into the brake hanger hole of the frame, and it is easy to be skewed during the operation to damage the nylon bushing. [0004] When the original press-fitting tool is used for press-fitting, the end face of the nylon sleeve is not easy to get close to the end face of the frame brake hanger hole, resulting in a gap, which affects the installation quality. [0005] It can be seen that the original installation method has the problems of cumbersome steps and low installation efficien...
