The technical solution of the utility model is that:

horizontal adds clamping apparatus for light rail train axle box, including the base, its special character lies in: set up ladder cylinder positioning seat on the base, at ladder cylinder positioning seat top installation clamp plate, lie in ladder cylinder positioning seat rear on the base and set up flexible first hydro-cylinder around setting up, the first push rod of extension about installing on the piston rod of first hydro-cylinder, the first push rod left and right sides sets up the second push rod respectively, the second push rod extends forward through the ladder cylinder positioning seat left and right sides, and sets up vertical ascending first claw that colludes at second push rod front end, sets up two flexible second hydro-cylinders from top to bottom about on the base, colludes the claw at the second that the piston rod top of second hydro-cylinder set up the level and arrange.

Further preferably, three positioning rods are arranged on the base and around the stepped cylindrical positioning seat, and circumferential pre-positioning is carried out on the shaft box body.

Further preferably, a threaded rod is arranged at the top end of the stepped cylindrical positioning seat, and the pressing plate and the threaded rod are installed through threads.

Further preferably, the second cylinder on the left side is provided on the right side of the second push rod on the left side, and the second cylinder on the right side is provided on the left side of the second push rod on the right side.

The utility model has the advantages that:

because of the stepped cylindrical positioning seat arranged on the base, the bearing hole of the shaft box body is sleeved on the stepped cylindrical positioning seat, and the shaft box body is horizontally positioned; the first oil cylinder is arranged behind the stepped cylindrical positioning seat and stretches back and forth, and the first hook claws are indirectly connected with piston rods of the first oil cylinder through the first push rod and the second push rod, so that the first oil cylinder is started, the two first hook claws synchronously pull the left side and the right side of the axle box body backwards, and under the circumferential free adjustment action of the axle box body by taking the stepped cylindrical positioning seat as a circle center, the two first hook claws finally tension the axle box body left and right, and circumferentially position the axle box body; the pressing plate is arranged at the top end of the stepped cylindrical positioning seat, the two second oil cylinders which are arranged on the base from left to right and are telescopic up and down, the second hook claws are arranged at the top ends of piston rods of the second oil cylinders, the pressing plate is screwed down, the two second oil cylinders are started, and the two second hook claws are pressed against the top surface of the axle box body to vertically position the axle box body; the axle box body positioning operation is simple, time and labor are saved, the production efficiency is improved, the stability of the axle box body positioning structure is improved, the axle box body machining error is greatly reduced, and the product quality is improved.
