Description

Technical Field

[0001] This utility model relates to the field of main bearing cover processing technology, specifically an auxiliary device for processing automotive engine main bearing covers. Background Technology

[0002] A car engine converts other forms of energy into mechanical energy to power the vehicle. Depending on the power source, car engines can be categorized as diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid engines. The main bearing cap of a car engine requires machining during production, and this machining process necessitates securing the bearing cap in place.

[0003] Traditional bearing cover fixing mechanisms have certain shortcomings in use. Traditional methods use bolts to fix the bearing cover, which is a relatively simple method and can lead to accidental movement of the bearing cover, reducing the processing quality of the bearing cover and resulting in poor fixing effect. Therefore, we propose an auxiliary device for processing automotive engine main bearing cover. Utility Model Content

[0023] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0024] An auxiliary device for machining the main bearing cap of an automobile engine includes a base plate 1. A fixing plate 6 is fixedly connected to the top of the base plate 1. A drive motor 18 is installed at the bottom of the fixing plate 6. A threaded rod 10 is fixedly connected to the output end of the drive motor 18. The threads at both ends of the threaded rod 10 have opposite directions of rotation. A collar 17 is fixedly connected to the bottom of the fixing plate 6. The threaded rod 10 extends into the collar 17 and is rotatably connected to the collar 17. A threaded sleeve 16 is threadedly connected to the outside of the threaded rod 10. A sliding plate 11 is fixedly connected to the top of the threaded sleeve 16. The sliding plate 11 is slidably connected to the fixing plate 6. A support plate 12 is fixedly connected to the top of the sliding plate 11. A bearing cap 13 abuts against the surface of the support plate 12. A cover plate 15 is provided on the top of the support plate 12. The cover plate 15 abuts against the surface of the bearing cap 13. A fastening bolt 14 is threadedly connected to the top of the cover plate 15.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, the bottom of the fastening bolt 14 extends into the support plate 12. A side groove 8 is provided in the fixing plate 6. A movable plate 5 is slidably connected to the bottom plate 1. A steel rod 9 is fixedly connected to the top of the movable plate 5. A limit plate 7 is fixedly connected to the top of the steel rod 9. The drive motor 18 drives the threaded rod 10 to rotate. Since the threaded rod 10 and the threaded sleeve 16 are threadedly connected, the threaded sleeve 16, the sliding plate 11, and the support plate 12 can be moved, causing the support plate 12 and the side of the bearing cover 13 to abut against each other. Then the cover... Plate 15 is placed on top of bearing cover 13 so that cover plate 15 and bearing cover 13 abut against each other, and fastening bolt 14 is rotated so that the bottom of fastening bolt 14 extends into support plate 12. Then, limiting plate 7 is slid in side groove 8 so that limiting plate 7 and slide plate 11 abut against each other. Limiting plate 7 and side groove 8 are positioned opposite each other. Limiting plate 7 extends into side groove 8 and slides in connection with side groove 8. Limiting plate 7 is made of stainless steel. Anti-slip texture is provided on the side end of limiting plate 7. Limiting plate 7 abuts against the surface of slide plate 11.

[0026] The support plate 12 can be moved by the power of the drive motor 18. The support plate 12 can abut and fix the bearing cover 13. At the same time, the cover plate 15 can abut the top of the bearing cover 13. By using the combination of the two methods, the fixing effect of the bearing cover 13 can be improved, the bearing cover 13 can be prevented from moving accidentally, and the processing quality of the bearing cover 13 can be improved.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, the base plate 1 has an insertion hole 3, and an insertion rod 4 is inserted into the insertion hole 3.

The radii of the multiple insertion holes 3 are the same. The support plate 12 and the cover plate 15 are both arc-shaped and made of stainless steel.

[0028] The movable plate 5 can be fixed by inserting the rod 4 into the hole 3. At the same time, the abutting action of the limiting plate 7 and the sliding plate 11 can further prevent the sliding plate 11 from moving unexpectedly, thereby improving the stability of the support plate 12.

[0029] The working process of this utility model is as follows: When the auxiliary device for processing the main bearing cover of an automobile engine designed in this scheme is in operation, the bearing cover 13 is placed on the side of the support plate 12, and the threaded rod 10 is rotated by the drive motor 18. Since the threaded rod 10 and the threaded sleeve 16 are threadedly connected, the threaded sleeve 16, the sliding plate 11 and the support plate 12 can be moved, so that the support plate 12 and the side of the bearing cover 13 abut against each other. Then, the cover plate 15 is placed on top of the bearing cover 13, so that the cover plate 15 and the bearing cover 13 abut against each other. The fastening bolt 14 is rotated so that the bottom of the fastening bolt 14 extends into the support plate 12. Then, the limiting plate 7 slides in the side groove 8, so that the limiting plate 7 and the surface of the sliding plate 11 abut against each other. Then, the insertion rod 4 is inserted into the moving plate 5 and the insertion hole 4, which can further fix the sliding plate 11 and the support plate 12, improve the firmness of the bearing cover 13, and facilitate the processing of the bearing cover 13.
