Description

Technical Field

[0001] This utility model relates to the field of cylinder liner machining auxiliary tools, specifically a cylinder liner fixing tool that facilitates angle adjustment. Background Technology

[0002] Cylinder liners are indispensable components of internal combustion engines. As the track for piston movement and a part of the combustion chamber, their machining accuracy directly affects the engine's power, economy, and reliability. During cylinder liner machining, fixed fixtures play a crucial role, ensuring the cylinder liner remains stable during processing and preventing machining errors caused by vibration, displacement, or other factors, which could affect the dimensional accuracy and surface quality of the cylinder liner.

[0003] In actual machining, cylinder liners often need to have their angles adjusted according to different machining process requirements to meet specific machining needs. However, current fixed tooling lacks flexible angle adjustment functions, which means that when machining cylinder liners with different angle requirements, tooling needs to be changed frequently or complex auxiliary operations are required, reducing production efficiency and making it difficult to adapt to diverse machining needs.

[0021] Please see Figure 1-2 This utility model provides a technical solution: a cylinder liner fixing fixture for easy angle adjustment, comprising:

[0022] Base plate 1;

[0023] The cylinder 14 has a vertical plate 2 on the upper surface of the base plate 1, and one side of the vertical plate 2 is hinged to the bottom of the cylinder 14.

[0024] Specifically, cylinder 14 is disposed on one side of the upper surface of vertical plate 2;

[0025] The curved plate 4 has multiple support rods 3 at its bottom, which are set on the upper surface of the base plate 1.

[0026] A central shaft 8 is set at the center of the arc plate 4. A bushing 7 is rotatably connected to the central shaft 8. A first connecting rod 9 and a second connecting rod 10 are connected to the bushing 7. A through groove 4-1 is opened on the arc plate 4. The first connecting rod 9 passes through the through groove 4-1. The second connecting rod 10 is hinged to the telescopic end of the cylinder 14.

[0027] Specifically, the first connecting rod 9 and the second connecting rod 10 are located on both sides of the bushing 7 and are arranged opposite to each other;

[0028] Support block 12 is located at the end of the first connecting rod 9, and a three-jaw chuck 13 is provided on the side of the support block 12 away from the arc plate 4.

[0029] Specifically, the bottom of the support block 12 is arc-shaped and the top is flat.

[0030] As an embodiment of the present utility model, the arc plate 4 is provided with two pairs of fixing rods 6, and a pair of bearing seats 15 are provided on the two pairs of fixing rods 6, and the central shaft 8 is provided between the pair of bearing seats 15;

[0031] Specifically, each bearing seat 15 is disposed between each pair of fixed rods 6. The fixed rods 6 are fixed to the arc plate 4, the fixed rods 6 and the bearing seats 15, and the central shaft 8 and the pair of bearing seats 15 by welding. The rotating sleeve 7 is rotatably disposed on the central shaft 8 and located between the pair of bearing seats 15.

[0032] As an embodiment of the present utility model, a pair of arc-shaped grooves 5 are provided on the arc plate 4 and on both sides of the through groove 4-1, and a positioning block 11 is provided through the first connecting rod 9. The positioning block 11 is slidably disposed in the pair of arc-shaped grooves 5.

[0033] Specifically, when the first connecting rod 9 rotates around the central axis 8, it can drive the positioning block 11 to rotate, so that the positioning block 11 slides in a pair of arc-shaped grooves 5, thereby preventing the first connecting rod 9 from shaking or shifting when it rotates.

[0035] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements.

[0036] The working principle and usage process of this utility model are as follows: First, the cylinder liner is fixed using the three-jaw chuck 13. Then, the cylinder 14 is started. When the extension or retraction end of the cylinder 14 extends or retracts, it drives the second connecting rod 10, which is hinged to its output end, to rotate. The second connecting rod 10 drives the bushing 7 to rotate on the central shaft 8. The bushing 7 drives the connected first connecting rod 9 to rotate. The first connecting rod 9 drives the support block 12 to rotate. The support block 12 drives the three-jaw chuck 13 to rotate. (The second connecting rod 10, bushing 7, first connecting rod 9, support block 12, and three-jaw chuck 13 all rotate around the axis of the central shaft 8. The second connecting rod 10, bushing 7, central shaft 8, first connecting rod 9, fixing rod 6, positioning block 11, support block 12, and three-jaw chuck 13 constitute an angle adjustment assembly, the cross-sectional view of which is shown below.) Figure 2 As shown in the figure, the tilt angle of the three-jaw chuck 13 is then adjusted, and the cylinder liner is ground and processed. After one part of the cylinder liner is processed, the cylinder liner angle is adjusted again by restarting the cylinder 14. This utility model adjusts the tilt angle of the cylinder liner by using the cylinder 14, thereby meeting the processing requirements of different cylinder liner angles. It is easy to operate, improves processing efficiency, and has a simple overall structure, thus reducing production costs.
