Description

Technical Field

[0001] This utility model belongs to the technical field of diesel engine frame main bearing hole centerline measurement, specifically relating to a diesel engine frame main bearing hole centerline measurement device. Background Technology

[0002] When the main bearing bush of a diesel engine burns out, the high temperature generated during the burning process can easily cause deformation of the bearing hole in the engine frame and misalignment of the center line. In addition, diesel engines that have been running for a long time may also have their bearing hole center line misaligned due to engine frame deformation, which will significantly affect the working performance of the bearing bush.

[0003] Currently, existing diesel engine frame main bearing hole centerline measuring devices typically use laser measuring equipment for measurement. However, traditional laser measuring equipment for diesel engine frame main bearing hole centerline is not only expensive but also requires operation by specialized personnel. This significantly increases repair costs after a crankshaft failure in a diesel engine, thus reducing the convenience of measuring the centerline of the diesel engine frame main bearing hole. Utility Model Content

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a diesel engine frame main bearing hole centerline measuring device, including a diesel engine frame 1, a measuring frame 2 passing through the inner side of the diesel engine frame 1, two connecting seats 3 fixedly connected to one end of the measuring frame 2, a limit plate 4 rotatably connected to one end of the two connecting seats 3, and a T-shaped slider 5 slidably connected to the inner side of the measuring frame 2.

[0026] One end of the T-shaped slider 5 is fixedly connected to an indicator ring 6. A scale 7 is provided on the surface of the measuring frame 2. One end of the connecting seat 3 is fixedly connected to a first connecting ring 8. One end of the T-shaped slider 5 is fixedly connected to a second connecting ring 9. A connecting rope 11 passes through the inner side of the first connecting ring 8 and the second connecting ring 9. One end of the connecting rope 11 is fixedly connected to a limit ball 10.

[0027] Preferably, the indicator ring 6 is sleeved on the outer wall of the measuring frame 2, and the indicator ring 6 can form a sliding connection structure with the measuring frame 2 through the T-shaped slider 5. The size of the limiting ball 10 is larger than the inner diameter of the first connecting ring 8.

[0028] It should be noted that the size of the limiting ball 10 is larger than the inner diameter of the first connecting ring 8 to prevent the connecting rope 11 from pulling it out from the inside of the first connecting ring 8.

[0029] In practical use, one end of the connecting rope 11 is passed through the first connecting ring 8 and the second connecting ring 9, and then the measuring frame 2 is passed through the main bearing hole inside the diesel engine frame 1. The limiting plate 4 is used to hold the diesel engine frame 1 in place. Then, through the sliding connection structure between the indicator ring 6 and the measuring frame 2, the indicator ring 6 is moved to the outlet of the main bearing hole. At this time, according to the position of the indicator ring 6 on the scale 7, the centerline of the main bearing hole of the diesel engine frame 1 can be measured conveniently.

[0030] It should be noted that after the indicator ring 6 is moved out of the main bearing hole outlet, by aligning one end of the connecting rope 11 with the end of the main bearing hole outlet of the diesel engine frame 1, the position of the connecting rope 11 passing through the second connecting ring 9 will be moved under the pull of the connecting rope 11 until the indicator ring 6 is flush with the main bearing hole outlet. In this way, the measurement accuracy can be further improved.

[0031] Preferably, a pull rod 12 is inserted through one end of the connecting seat 3, and a movable block 13 is connected to the through end of the pull rod 12. A limit plug 14 is fixedly connected to one end of the movable block 13. A spring 15 is sleeved on the outer wall of the pull rod 12. A limit slot 16 is opened at one end of the limiting plate 4. The end of the limit plug 14 away from the movable block 13 is adapted to the size of the limit slot 16. The limit plug 14 can form an elastic structure with the connecting seat 3 through the pull rod 12, the movable block 13, and the spring 15.

[0032] In actual use, the movable block 13 is pulled by the lever 12 to cause the limiting block 14 to retract. At this time, one end of the limiting block 14 will disengage from the limiting slot 16 at the end of the limiting plate 4. Then, the limiting plate 4 is flipped and folded up, which makes it convenient for the device to be folded and stored later.

[0033] Conversely, by pulling the movable block 13 with the lever 12, the limiting insert 14 is retracted, and then the limiting plate 4 is flipped in the opposite direction so that the limiting plate 4 and the connecting seat 3 can be in a vertical state. At this time, the lever 12 is released, and the limiting insert 14 will pop out under the action of the spring 15 and be inserted into the limiting slot 16 to achieve fixation.

[0034] Working principle: First, the movable block 13 is pulled by the pull rod 12, causing the limiting block 14 to retract. Then, the limiting plate 4 is flipped in the opposite direction, so that the limiting plate 4 and the connecting seat 3 are in a perpendicular state. At this time, the pull rod 12 is released, and the limiting block 14 will pop out under the action of the spring 15 and insert into the limiting slot 16 to achieve fixation. One end of the connecting rope 11 is passed through the first connecting ring 8 and the second connecting ring 9. Then, the measuring frame 2 is passed through the main bearing hole on the inner side of the diesel engine frame 1. Finally, the limiting plate 4 is used to hold the diesel engine frame 1 in place. Then, through the sliding connection structure between the indicator ring 6 and the measuring frame 2, the indicator ring 6 is moved to the through-hole of the main bearing hole. At this time, according to the stopping position of the indicator ring 6 on the scale 7, the center line of the main bearing hole of the diesel engine frame 1 can be easily measured. Finally, the movable block 13 is pulled by the pull rod 12 to drive the limit plug 14 to retract. At this time, one end of the limit plug 14 will disengage from the limit slot 16 at the end of the limit plate 4. Then, the limit plate 4 is flipped and folded up, so as to facilitate the subsequent folding and storage of the device.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
