Technical Field
[0001] The utility model belongs to the technical field of internal combustion engine maintenance and manufacturing, and in particular relates to an angle adjustment device for a cylinder sleeve rolling tool. Background Art
[0002] In the manufacturing process of modern internal combustion engines, the processing quality of the support shoulder on the upper end of the cylinder liner has a crucial impact on the performance and life of the engine. As one of the main stress-bearing parts, it is the part that is most subjected to mechanical and thermal stresses during the operation of the engine. However, the support shoulder is also the weakest part in the cylinder liner structure design. Fatigue failure is prone to occur at the fillet of the support shoulder, which can lead to cracks or even fractures in the cylinder liner. In order to improve the fatigue strength of the cylinder liner, one of the common treatment methods is to perform linear rolling on the fillet of the support shoulder.
[0003] In order to achieve linear loading of rolling force, rolling tools usually adopt a design in which a roller is installed on one end of the cutter body spring or one end of the hydraulic cylinder. When the roller is subjected to radial rolling force, the roller can perform elastic movement under the action of the spring. However, this type of rolling tool has certain limitations in practical applications. The most common limitation is that these rolling tools need to be installed on CNC machine tools. Although CNC machine tools can provide high-precision processing, they often lack an effective angle fine-tuning mechanism, which means that during the rolling process, the contact angle between the rolling tool and the part to be processed of the cylinder liner cannot be accurately controlled, resulting in poor rolling effect. This limitation makes it difficult for the processing quality of the cylinder liner to meet the high-precision requirements of modern engine manufacturing. Therefore, there is a need for an angle adjustment device for cylinder liner rolling tools that can achieve precise control of the contact angle of the rolling tool during the rolling process and improve the processing quality of the cylinder liner.

[0027] The adjustment plate 2 is a square plate, and the concave cavity 2-1 is opened at the center position of the adjustment plate 2 and is adapted to the angle adjustment dial 3, that is, the adjustment plate 2 is nearly circular, and a boss 2-2 is provided on the inner wall of the adjustment plate 2 to match the arc-shaped notch 3-1 of the angle adjustment dial, that is, the boss 2-2 is provided with an arc surface that fits the arc-shaped notch 3-1, and the arc size of the arc surface is smaller than the arc size of the arc-shaped notch 3-1. Preferably, the boss 2-2 is located in the middle of the arc-shaped notch 3-1, dividing the arc-shaped notch 3-1 into two parts, one part is used to adjust the angle, and the other part is used for positioning.
[0028] The positioning component includes an angle adjustment pad 5 for adjusting the rotation angle of the angle adjustment dial 3 and a positioning screw 4 for positioning the angle adjustment dial 3 after rotation.

The positioning screw 4 passes through the adjustment plate 2 through the outer thread of the adjustment plate 2, that is, the adjustment plate 2 is provided with a threaded hole adapted to the positioning screw 4. The positioning screw 4 can be screwed and adjusted in the threaded hole, so as to abut against one end of the arc-shaped notch 3-1 of the angle adjustment dial in the concave cavity 2-1 of the adjustment plate 2 to position the angle adjustment dial 3. The angle adjustment pad 5 is detachably arranged at the other end of the arc-shaped notch 3-1 and abuts against the side wall of the boss 2-2. The angle adjustment pad 5 is adapted to the shape of the arc-shaped notch 3-1 and is an arc-shaped block structure. A plurality of angle adjustment pads 5 of different arc sizes can be arranged, and the angle adjustment dial 3 can be fine-tuned and rotated by replacing angle adjustment pads 5 of different arc sizes. A connecting plate 3-2 adapted to the angle adjustment pad 5 is provided on the arc-shaped notch 3-1. The angle adjustment pad 5 is set on the connecting plate 3-2 by means of bolts 5-1 and abuts against the boss 2-2.

[0031] The adjustment plate 2 is connected to the fastening nut through the connecting screw 1-4 penetrating the guide slot 1-1, and the angle adjustment turntable 3 is connected to the fastening nut through the rotating shaft 1-5 penetrating the guide slot 1-1. When the adjustment plate 2 drives the angle adjustment turntable 3 to move horizontally for adjustment and the angle adjustment turntable 3 rotates to adjust the angle, it is necessary to loosen each fastening nut, and the adjustment plate 2 moves horizontally in the corresponding guide slot 1-1 through each connecting screw 1-4, and the angle adjustment turntable 3 rotates in the corresponding guide slot 1-1 through the rotating shaft 1-5 while also following the adjustment plate 2 to move horizontally in the guide slot 1-1.
