Embodiment Construction

[0019] Such as figure 1 Is a schematic diagram of the structure of the present invention, figure 2 It is a top view of the present invention. A hole measuring device for the axle holding box includes a gauge board 1, a main inspection shaft 4 and a secondary inspection shaft 5. The gauge board 1 is provided with a shaft sleeve 3 and a shaft hole 6, and the main inspection shaft 4 The auxiliary inspection shaft 5 is inserted into the shaft sleeve 3 and the shaft hole 6 respectively. The gauge board 1 is a ring with a mop. The shaft sleeve 3 is vertically welded to the mop of the gauge board 1. The shaft hole 6 is uniformly distributed around the circumference of the gauge board 1. A positioning block 2 is welded symmetrically on both sides of the gauge board 1.

[0020] A method of using the axle box hole measuring device, according to the actual size of the parts to make the axle box hole measuring device, the axle sleeve 3 and the axle hole 6 on the axle box hole measuring d...

Abstract

The invention relates to the technical field of diesel locomotive, in particular to an axle-hang box hole measuring device and a using method thereof. The device comprises a checking tool plate, a main checking shaft and an auxiliary checking shaft, a shaft sleeve and a shaft hole are disposed on the checking tool plate, and the main checking shaft and the auxiliary checking shaft are inserted into the shaft sleeve and the shaft hole respectively. The hole measuring device is manufactured according to actual size of a part, actual assembly state is simulated, whether each hole site of an axle-hang box is qualified or not is checked according to whether the main checking shaft and the auxiliary checking shaft can smoothly penetrate through a support frame hole and an installing hole of the axle-hang box or not, the device is simple, practical, convenient and rapid, the efficiency is greatly improved, simultaneously the manufacturing of the hole measuring device is simple, the cost is low, and good techno-economic effect is achieved.

Description

Technical field [0001] The invention relates to the technical field of diesel locomotives, in particular to an axle suspension box hole measuring device and a use method thereof. Background technique [0002] The axle holding box is an important safety key part of the running part of the diesel locomotive. The cast steel part has a bracket hole ￠27mm on the back of the structure. When the parts are assembled, the bracket shaft is inserted into the bracket hole and connected to the gear box cover for positioning. Therefore, there are requirements for the size and accuracy of the hole center position. If there is an offset, the bracket axis cannot be assembled, which will cause the assembly of the axle box and components to fail. Because the center of the hole is a spatial dimension, conventional measuring tools cannot accurately measure it, and must be measured by three coordinates. Due to the large production volume of the axle box, on the one hand, the cost of three coordinate m...
