Description
Technical Field
[0001] The utility model relates to the technical field of axle-holding box installation, in particular to an assembly and positioning tool for a locomotive axle-holding box. Background Art
[0002] The axle box is a very important part of the locomotive. Its main function is to bear the weight of the locomotive wheels and frame, and at the same time it plays the role of sealing dust, waterproof and dustproof. The axle box is generally composed of two parts: the upper part and the lower part. The upper part is usually called the copper cover or cover plate, and the lower part is called the steel shell or shell. The axle box is equipped with bearings and bearing seats. When the locomotive is running, the bearings rotate continuously and move forward on the track. The axle box shell is usually made of a section of cast iron, and the copper cover is a slightly smaller copper part. Gaskets are inserted between them and they are screwed together with set bolts.
[0003] The existing Chinese utility model patent with reference announcement number CN212145343U discloses a vertical processing and positioning tool for axle boxes of light rail locomotives, including a base, a three-jaw chuck with claws arranged upwards fixedly installed at the center of the base, wherein two claws are arranged radially symmetrically on the left and right, and the third claw is located at the rear side, a first bracket is fixedly installed in front of the three-jaw chuck on the base, and a front ejector pointing to the rear is installed on the first bracket through a thread; two second brackets arranged left and right are fixedly installed on the base behind the three-jaw chuck, wherein a fixed ejector is fixedly installed on one of the second brackets, and a movable ejector is installed on the other second bracket through a thread, and the fixed ejector is coaxial with the movable ejector; three support seats centered on the three-jaw chuck are fixedly installed on the bottom plate in a circumferential direction, and columns are fixedly installed on the outside of the circumference of the three support seats on the base, and a pressure arm is installed on the top of each column through a bolt. It can simplify the positioning process, improve the processing efficiency, and the positioning structure is firm, so as to prevent the light rail locomotive axle box from having a processing size deviation due to displacement and improve the product forming rate.
[0004] The axle holding box is generally a steel casting with high weight. During assembly, the locomotive axle needs to be located in the center of the box to ensure that the locomotive guide wheel is at a consistent distance from the center. The existing axle holding box positioning tooling cannot locate the box in the center of the locomotive axle, and the position of the box is generally limited by a clamp when fixing the box, which is very inconvenient.
