[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 This utility model provides a technical solution: a coaxiality detection device for the drive axle support shaft of a mining truck, comprising a base 1, a mounting plate 2, an adjusting rod 3, a first adjusting block 4, a first track 5, a bearing frame 6, a first electric telescopic rod 7, a pressing block 8, a second track 9, a second adjusting block 10, a second electric telescopic rod 11, a mounting seat 12, a connecting strip 13, a dial indicator 14, a gear 15, a connecting shaft 16, a connecting plate 17, a motor 18, and a guide rod 19.

[0033] Example 1: The existing method of adjusting and repositioning the spacing of the "V"-shaped frame using a second slide, a second slider, a second threaded hole, a threaded groove, and a second bolt is cumbersome and time-consuming. Therefore, this example uses the following technical solution: Figure 1 , Figure 2 and Figure 6 Since the limiting structure includes an adjusting rod 3, a first adjusting block 4, a first track 5, and a support frame 6, the outer surface of the adjusting rod 3 has a bidirectional threaded structure. The first adjusting block 4 is symmetrically threaded on the adjusting rod 3. The support frame 6 is slidable on the upper side of the base 1 through the adjusting rod 3 and the first adjusting block 4. Therefore, the distance between the left and right sets of support frames 6 can be adjusted according to the length of the shaft to be measured. The adjusting rod 3 is rotated to rotate on the left and right sets of mounting plates 2, so that the lower end of the symmetrically arranged first adjusting block 4 slides in opposite directions in the corresponding position of the first track 5. The left and right sets of first adjusting blocks 4 and the first track 5 adjust the distance between the symmetrically arranged support frames 6, so as to facilitate the quick adjustment of the distance between the support frames 6 to limit shafts of different sizes.

[0034] Example 2: In existing methods, the operator rotates a control handle during measurement to rotate the threaded rod, causing the threaded rod to lower the pressure block 8 to press against the shaft. However, this is cumbersome to operate. Therefore, this example uses the following technical solution: Figure 1 , Figure 2 and Figure 4 Since the first electric telescopic rod 7 is bolted between the top of the support frame 6, and the pressure block 8 has a lifting structure inside the support frame 6, the shaft is placed inside the left and right sets of support frames 6, so that the bottom ends of the left and right ends of the shaft are respectively attached to the lower inner wall of the support frame 6. When the left and right sets of first electric telescopic rods 7 work, they drive the pressure block 8 to descend, so that the lower ends of the symmetrically arranged pressure blocks 8 are tightly pressed against the upper end of the shaft, thereby preventing the shaft from shifting during measurement.

[0035] Example 3: Existing methods adjust the position of the dial indicator 14 using components such as a through rod, a first threaded hole, and a first bolt. However, this method is cumbersome and requires specific tools. Therefore, this example uses the following technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 5 The adjustment structure includes a second track 9, a second adjusting block 10, a second electric telescopic rod 11, a mounting base 12, a connecting bar 13, a gear 15, a connecting shaft 16, a connecting plate 17, a motor 18, and a guide rod 19. The second adjusting block 10 is slidably connected inside the second track 9. The lower end of the connecting bar 13 has a serrated structure, and the lower rear end of the connecting bar 13 is meshed with the gear 15. The guide rod 19 is connected through the upper end of the mounting base 12. The dial indicator 14 slides on the upper side of the base 1 via the connecting bar 13 and the gear 15. Therefore, when the second electric telescopic rod 11 is working, it drives the mounting base 12 to rise and fall, and the mounting base 12 drives the dial indicator 14 to move up and down to adjust the height of the dial indicator 14. The operator pushes the mounting base 12 to allow the second adjusting block 10 to slide left and right inside the second track 9, adjusting the position of the dial indicator 14. When the motor 18 is working, it drives the connecting shaft 16 to rotate on the symmetrically arranged connecting plates 17. When the connecting shaft 16 rotates, it drives the gear 15 to rotate, allowing the gear 15 to mesh with the sawtooth structure at the lower end of the connecting bar 13. Meanwhile, the guide rod 19 moves inside the upper end of the mounting base 12. Through the guide rod 19 and the connecting bar 13, the dial indicator 14 can move stably. The "T"-shaped structure of the second adjusting block 10 can prevent it from dislodging from the interior of the second track 9, thus facilitating the adjustment of the position of the dial indicator 14 for measurement. All the electrical components mentioned above are existing technologies and will not be described in detail here.

[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
