Embodiment 1

[0039] Embodiment 1, a quick replacement method for maintenance of a ball hinge for a linkage mechanism. First, the damaged ball hinge in the linkage mechanism that needs to be replaced is removed from the linkage under the action of an external force, and cannot be damaged during the removal process. The connecting rod and the inner hole of the connecting rod where the ball hinge is installed; and then the good new ball hinge used to replace the damaged ball hinge is forced into the inner hole of the connecting rod rod under the action of external force, and the maintenance of the ball hinge for the connecting rod mechanism is completed. Quick replacement operation; the press-in of the new ball joint is an interference fit. During this press-in process, it is necessary to ensure the deflection angle of the two ball joints at both ends of the connecting rod and the symmetry of the ball joint after press-in, including the following key steps:

[0040] Step 1: Adjust the distance...

Embodiment 2

[0053] Embodiment 2, as shown in the accompanying drawings, the present invention also proposes a simple, practical, easy-to-operate tool that can be used for rapid replacement of the connecting rod 3 rubber-metal ball joint for on-site maintenance. Support frame, hydraulic booster 6, pressurized cylinder 5; The support frame includes top baffle plate 8, support bar 7 and support baffle plate 1, and top baffle plate 8 and support baffle plate 1 are installed and fixed on the two ends of support bar 7, and support The two ends of the rod 7 are provided with threads, which are connected and fixed with the top baffle 8 and the support baffle 1 through nuts, and the distance between the top baffle 8 and the support baffle 1 is adjusted by adjusting the fixed position of the nut; the support baffle 1 is provided with The press-out through hole with a diameter larger than the outer diameter of the ball joint is convenient to press out the ball joint in the connecting rod 3; 5 pressur...

Embodiment 3

[0054] The third embodiment differs from the second embodiment in that during the process of pressing the new ball joint, the new ball joint is prone to shake or rotate, which affects the installation angle of the new ball joint. In order to ensure the smooth installation of the new ball joint, A press-in guide cylinder 4 is set between the connecting rod 3 and the pressurizing cylinder 5. The press-in guide cylinder 4 is a hollow circular tube structure. The inner diameter of the hollow circular tube structure is the same as the inner hole diameter of the connecting rod 3. 4 The lower end is provided with a positioning step, and the press-in guide cylinder 4 is reliably arranged on the connecting rod 3, so that the ball joint can be smoothly pressed out of the inner hole of the connecting rod 3, and the press-in guide cylinder 4 is the new ball joint. The press-in provides a guiding function to ensure the smooth press-in of the new ball joint.

Abstract

The invention discloses a method for realizing quick maintaining and replacing of spherical hinges used in a link mechanism, and an auxiliary fixture. The auxiliary fixture is characterized by comprising a support frame, a hydraulic power assisting device and a pressurizing cylinder; the support frame comprises a top baffle, supporting rods and a support baffle, wherein the top baffle and the support baffle are fixedly mounted at the two ends of the supporting rods; extrusion through holes of which diameters are larger than the outer diameters of the spherical hinges are formed in the support baffle to facilitate the extrusion of the spherical hinges in connecting rods; the pressurizing cylinder is arranged between the support baffle and the hydraulic power assisting device, and is used for extruding old spherical hinges required to be replaced in the connecting rods and pressing new spherical hinges into the connecting rod; the hydraulic power assisting device is fixedly mounted between the top baffle and the pressurizing cylinder; the connecting rods of which spherical hinges are required to be replaced are fixed on a support plate. According to the invention, the pressurizing cylinder can quick complete quick positioning of the spherical hinges, and the pressing-in and extrusion actions of the spherical hinges can be realized by the hydraulic power assisting device so as to complete the replacement of the spherical hinges.

Description

technical field [0001] The invention relates to a maintenance and quick replacement method for a rubber-metal ball joint used in a locomotive linkage mechanism and its auxiliary tooling. Specifically, the ball joint that needs to be replaced is quickly pressed out of the connecting rod, and a new ball joint is quickly pressed into the connecting rod. Rod, the operation method and auxiliary tooling for completing the maintenance and replacement of the ball joint. Background technique [0002] The connecting rod mechanism for locomotives belongs to the components of the locomotive transmission and damping system, so there are relatively high requirements for the precision and strength of the parts. The connecting rod mechanism mainly includes the connecting rod body and the rubber-metal ball joint. During the assembly process of the connecting rod, it is necessary to force the rubber metal ball joint into the inner hole of the connecting rod rod under the action of external fo...
