Embodiment 1

[0048] figure 1 The front view and top view of the assembly tooling for the square hole of the axle box of industrial and mining motors provided by the embodiment of the present invention, figure 2 For the front view and top view of the frame of the industrial and mining electric locomotive provided by the embodiment of the present invention, refer to figure 1 and figure 2 As shown, the assembly tooling for the square hole of the axle box of the industrial and mining electric locomotive provided by the present invention is used to assemble the vehicle frame 200 of the industrial and mining electric locomotive. Two axle box square holes 25 are respectively arranged on the corresponding front axle 23 and rear axle 24 on the right side plate 22,

[0049] The tooling assembly 100 includes: a tooling platform 10 located below the vehicle frame 200 and two detachable positioning assemblies 11 installed on the top surface of the tooling platform 20, and the two positioning assembli...

Embodiment 2

[0056] image 3 The schematic diagram of the structure of the assembly tooling for the square hole of the industrial and mining motor axle box provided by the embodiment of the present invention, refer to figure 1 , figure 2 and image 3 As shown, the height of the block 12 is greater than the height of the square hole 25 of the axle box, and the size of the block 12 along the length of the vehicle body is smaller than the width of the square hole 25 of the axle box.

[0057] Specifically, the height of the clamping block 12 is greater than the height of the axle box square hole 25, so as to ensure that when the vehicle frame 200 is hoisted and placed on the assembly tooling 100, the vehicle frame 200 is supported by the positioning assembly 11 in the axle box square hole 25, The bottom edge of the vehicle frame 200 will not touch the tooling platform 10, that is, the size of the assembly is only affected by the size of the axle box square hole 25 itself, and will not be di...

Embodiment 3

[0063] Figure 4 For the structural schematic diagram of the connecting part of the adjusting block and the clamping block of the assembly tooling provided by the embodiment of the present invention, refer to figure 1 and Figure 4 As shown, the clamping block 12 is provided with a protruding block 14 corresponding to the position of the adjusting block 13 , and the adjusting block 13 and the protruding block 14 are connected by an inner bolt 15 . Specifically, the protruding block 14 is welded on the clamping block 12 , and the protruding block 14 and the adjusting block 13 are correspondingly provided with holes for installing the inner bolt 15 .

[0064] On the basis of the above-mentioned embodiments, this embodiment is provided with a bump 14 on the block 12, and the adjustment block 13 is connected to the block 12 through the bump 14, compared to directly connecting the adjustment block 13 to the block 12 The method is simpler and easier to implement in terms of techno...

Abstract

The invention provides an assembling tool for industrial-mineral electric locomotive axle housing square holes. The assembling tool is used for assembling a locomotive frame of an industrial-mineral electric locomotive. The locomotive frame includes a left side plate and a right side plate which are relatively arranged to one another. A front shaft and a rear shaft corresponding to the left side plate and the right side plate are separately provided with two axle housing square holes. The assembling tool includes a tooling platform below the electric locomotive frame and two positioning assemblies which are detachably installed on the top surface of the tooling platform. The two positioning assemblies are correspondingly arranged in the axle housing square holes of the front shaft and therear shaft. Each positioning assembly includes a clamping block which can be enclosed into the axle housing square holes and a plurality of adjustment blocks which are detachably installed on the clamping block. The adjusting blocks are mounted on one side, facing the literal edge of the axle housing square holes, of the clamping block. A clearance for positioning a vertical plate of an axle housing is formed between the positioning assemblies and the corresponding axle housing square holes. The assembling tool for industrial-mineral electric locomotive axle housing square holes has high accuracy.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a tool for assembling a square hole in an axle box of an industrial and mining motor. Background technique [0002] Industrial and mining electric locomotives are widely used in mines, coal mines and other fields, and their main function is to carry out traction and transportation of ore, coal, personnel and auxiliary materials. Industrial and mining electric locomotives belong to rail transportation. If the assembly error of the running part is large, it will cause derailment and other phenomena. Therefore, the assembly and welding process of industrial and mining electric locomotives requires high precision. It is necessary to ensure that the upper planes of the four axle boxes are at a horizontal position, and that the centerlines of the square holes of the two axle boxes are parallel to each other. [0003] In the prior art, the way of assembling the square holes of the axle ...
