Abstract

The invention discloses a drilling die for a hook supporting plate hole of a railway vehicle, belongs to the technical field of railway vehicles and machinery, and relates to a drilling die for a railway vehicle. The mold comprises two split-type mold plates which are symmetrical left and right, a first lining is embedded in the middle of each mold plate, a second lining is embedded in the end of each mold plate, a first positioning check block is arranged on the side edge of the end of each mold plate, a second positioning check block is arranged on the side edge of the middle of each mold plate, and cushion blocks are arranged on the upper face and the lower face of each mold plate respectively. The drilling jig has the beneficial effects that the original integral drilling jig is improved, and the split drilling jig is adopted, so that the labor intensity of an operator is reduced, and the drilling jig is convenient to assemble and disassemble. Moreover, the split type drilling jig avoids the transverse displacement of the hook supporting plate hole caused by the out-of-tolerance of the inner distance of the middle beam, and can fundamentally improve the installation precision of the car coupler, thereby improving the running safety of the car.

Description

technical field [0001] The utility model relates to a hole drilling die for a hook pallet for railway vehicles, belonging to the technical field of railway vehicles and machinery, and relates to a drilling die for railway vehicles. Background technique [0002] At present, most of the drilling dies for the middle beam hook pallet holes of domestic railway freight cars are integral. After the position of the hole on one side is fixed, the position of the hole on the other side is limited, and its accuracy cannot be guaranteed. With the development of railway freight cars, in order to ensure the safety of the connection of adjacent vehicles, the requirements for the installation of couplers have gradually increased. SUMMARY OF THE INVENTION [0003] The problem to be solved by the present invention is to provide a rail vehicle hook pallet hole drilling die which avoids the deviation of the drilling size due to the excessive inner distance of the middle beam and improves the ...
