Description

Technical Field

[0001] This utility model belongs to the field of engine cylinder block processing technology, specifically an engine cylinder block milling device. Background Technology

[0002] The engine cylinder milling device is a high-efficiency and precise machining equipment that uses a milling cutter to mill the surface of the engine cylinder block to achieve the required shape, size and surface roughness. This device is widely used in the engine manufacturing process of the automotive, construction machinery and other industries, and is an important part of ensuring the quality and performance of the engine cylinder block.

[0003] Precise positioning is a crucial step before milling engine cylinders, directly impacting stability during the milling process and the final machining quality. However, existing positioning devices have some significant drawbacks in practical applications, especially when dealing with uneven or concave engine cylinder surfaces. As a core component of the engine, the cylinder block often exhibits varying degrees of unevenness due to casting, forging, or previous machining processes. Traditional positioning devices typically use direct-drive positioning plates to limit the cylinder's sides. These plates are designed with flat surfaces to contact and fix the cylinder to an ideal, flat surface. However, when facing uneven cylinder surfaces, these flat positioning plates often fail to fit tightly, resulting in poor positioning. During milling, if the cylinder is not effectively positioned, it may move or deflect, affecting milling accuracy and uniformity. This can also lead to abnormal contact between the tool and the cylinder surface, damaging the tool or the cylinder itself. Furthermore, unstable positioning can cause vibration and noise, further reducing machining quality and efficiency. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses the power of a drive motor to cause the meshing tooth plates one and two on both sides of the gear to move relative to each other, thereby limiting the two sides of the cylinder body with two sets of limiting plates. At the same time, the round block is moved into the round groove by the reaction force of the cylinder body and squeezes the spring. Compared with the traditional device, this device can ensure that the cylinder body remains stable during processing and avoid processing errors caused by vibration or external force interference, thereby ensuring the processing quality and performance of the engine cylinder body. At the same time, the cooperation between the limiting plates, round groove, round block and spring can more accurately control the position of the cylinder body during processing, preventing it from moving or deflecting during milling, thereby improving processing accuracy. Furthermore, this device can adapt to cylinder bodies of different sizes and shapes, thereby increasing processing flexibility and versatility.

[0013] 2. This utility model moves the first sleeve block on the surface of the first threaded rod by rotating the turntable, and then moves the second sleeve block on the surface of the second threaded rod by the power of the servo motor, thereby changing the position of the milling device. Compared with the traditional device, this device can ensure that different areas of the cylinder block are ground evenly and fully, avoiding under-grinding or over-grinding in some areas. It can also better adapt to the complex shape and unevenness of the cylinder block surface, thereby improving the processing quality. At the same time, by optimizing the grinding effect, the sealing, wear resistance and corrosion resistance of the cylinder block can be improved, thereby extending the service life of the engine, reducing micro-cracks and defects on the cylinder block surface, and improving the overall strength and rigidity of the cylinder block.

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.

[0021] like Figures 1 to 5As shown, this utility model provides an engine cylinder block milling device, including a U-shaped platform 1. A gear 2 is movably installed at the bottom of the U-shaped platform 1. A drive motor 3 is fixedly installed at the bottom of the gear 2. A toothed plate 4 and a toothed plate 5 are sequentially meshed on both sides of the gear 2. An L-shaped plate 7 is fixedly installed at one end of both toothed plate 4 and toothed plate 5. Connecting rods 6 are movably installed on the inner walls of both sides of the U-shaped platform 1, and the connecting rods 6 pass through the U-shaped platform 1. One connecting rod 6 and the L-shaped plate 7 are fixedly connected to toothed plate 4, and the other connecting rod 6 and the L-shaped plate 7 are fixedly connected to toothed plate 5. A limiting plate 8 is fixedly installed at the other end of the connecting rod 6. Several circular grooves 9 are opened on the inner side of the limiting plate 8. A circular block 10 is movably installed inside the circular groove 9. A spring 11 is provided between the circular groove 9 and the circular block 10.

[0022] The above solution ensures the stability of the cylinder block during machining, preventing machining errors caused by vibration or external interference, thus guaranteeing the machining quality and performance of the engine cylinder block. Furthermore, the cooperation between the limiting plate 8, the circular groove 9, the circular block 10, and the spring 11 allows for more precise control of the cylinder block's position during machining, preventing movement or deflection during milling and improving machining accuracy. This device can also adapt to cylinder blocks of different sizes and shapes, increasing machining flexibility and versatility.

[0023] like Figure 5 As shown, two sets of rectangular shells 12 are fixedly installed on the top of the U-shaped platform 1. A threaded rod 13 is movably installed inside the rectangular shell 12, and a socket block 14 is movably installed on the surface of the threaded rod 13. An N-shaped bracket 15 is fixedly installed on the top of the socket block 14. A turntable 16 is movably installed on one end of the rectangular shell 12, and the turntable 16 is fixedly connected to the threaded rod 13. A rectangular groove 17 is opened at the bottom of the N-shaped bracket 15. A threaded rod 28 is movably installed inside the rectangular groove 17. A socket block 29 is movably installed on the surface of the threaded rod 28, and a rectangular plate 20 is fixedly installed on the side of the socket block 29. A milling device 21 is provided on the surface of the rectangular plate 20. A servo motor 22 is fixedly installed on one end of the N-shaped bracket 15, and the servo motor 22 is fixedly connected to the threaded rod 28.

[0024] The above solution ensures that different areas of the cylinder block are evenly and thoroughly polished, avoiding under-polishing or over-polishing in certain areas. It also better adapts to the complex shape and unevenness of the cylinder block surface, thereby improving the processing quality. At the same time, by optimizing the polishing effect, the sealing, wear resistance and corrosion resistance of the cylinder block can be improved, thereby extending the service life of the engine. This reduces micro-cracks and defects on the cylinder block surface and improves the overall strength and rigidity of the cylinder block.

[0025] like Figure 2As shown, a motor protective cover 23 is provided at the bottom of the gear 2, and the drive motor 3 is located inside the motor protective cover 23. Heat dissipation holes 24 are provided on the surface of the motor protective cover 23.

[0026] The above solution is adopted: by setting a motor protective cover 23 at the bottom of the gear 2, and the drive motor 3 is located inside the motor protective cover 23, the drive motor 3 is protected from damage caused by impact from external objects. Heat dissipation holes 24 are opened on the surface of the motor protective cover 23 to improve the heat dissipation of the drive motor 3.

[0027] like Figure 2 As shown, four sets of support legs 26 are fixedly installed at the bottom of the U-shaped platform 1, and support leg pads 27 are fixedly installed at the bottom of each of the four sets of support legs 26.

[0028] The above solution is adopted: by fixing four sets of support legs 26 at the bottom of the U-shaped platform 1, and fixing support leg pads 27 at the bottom of each of the four sets of support legs 26, the pressure of the device can be distributed, thereby improving the stability of the device during operation.

[0029] like Figure 1 As shown, a reinforcing rib 25 is fixedly installed at the connection between the U-shaped platform 1 and the rectangular shell 12. The reinforcing rib 25 is triangular in shape.

[0030] The above solution is adopted: by fixing a reinforcing rib 25 at the connection between the U-shaped platform 1 and the rectangular shell 12, the firmness between the U-shaped platform 1 and the rectangular shell 12 is improved.

[0031] like Figure 5 As shown, the inner diameter of the rectangular groove 17 is equal to the outer diameter of the socket block 19, and the surface of the turntable 16 is provided with a sponge layer.

[0032] The above solution is adopted: by setting the inner diameter of the rectangular groove 17 to be equal to the outer diameter of the socket block 19, the socket block 19 becomes more stable when moving on the surface of the threaded rod 18. A sponge layer is provided on the surface of the turntable 16 to improve the comfort of the staff.

[0033] Working principle and usage process of this utility model:

[0034] In use, the operator places the engine block on the surface of the U-shaped platform 1, and then starts the drive motor 3 through an external switch. The power generated by the drive motor 3 causes the gear 2 to rotate. The rotation of the gear 2 causes the meshing toothed plates 4 and 5 on both sides to move relative to each other, thereby causing the two sets of limiting plates 8 to move synchronously, thus clamping the two sides of the engine block. At the same time, when the round block 10 contacts the surface of the cylinder, the round block 10 will be moved into the round groove 9 by the reaction force of the cylinder, and at the same time, it will compress the spring 11.

[0035] In use, the operator rotates the turntable 16, which causes the threaded rod 13 to rotate, thereby moving the socket block 14 on the surface of the threaded rod 13 and changing the position of the N-type bracket 15. Then, the operator starts the servo motor 22, and the power generated by the servo motor 22 causes the threaded rod 18 to rotate, causing the socket block 19 on the surface of the threaded rod 18 to move on its surface, thereby changing the position of the milling device 21.
