Description

Technical Field

[0001] This utility model belongs to the field of cylinder liner processing technology, and in particular relates to a cylinder liner clamping device. Background Technology

[0002] A cylinder liner is a cylindrical part that is fitted into the cylinder bore of the engine block. Together with the piston and cylinder head, it forms the combustion chamber. It provides a smooth and precise cylindrical surface for the reciprocating motion of the piston, ensuring that the piston can move smoothly up and down in the cylinder to complete the working cycle of intake, compression, power and exhaust.

[0003] During cylinder liner machining, a fixture is required to stably fix the cylinder liner on the machining equipment to ensure machining accuracy and safety, prevent the cylinder liner from flying off due to vibration or displacement during machining, and ensure the safety of operators. When using a fixture to clamp and fix the cylinder liner, the clamping end of the fixture contacts the cylinder liner surface, which may obstruct the machining position. Existing clamping devices do not have adjustment functions and cannot adjust the clamping position of the cylinder liner, affecting normal machining. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a cylinder liner clamping device that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a cylinder liner clamping device includes a worktable and a clamping assembly. The worktable includes a base and a platform body. The bottom of the platform body is fixedly connected to the top of the base. The clamping assembly includes four connecting blocks, four connecting seats, and four clamping ends.

By inserting the plug-in plate into the two plug blocks, the movement of the two plug blocks is restricted, thereby keeping the two adjusting plates stable.

[0011] To ensure a stable connection between the connecting blocks and the adjusting plates, preferably, the bottoms of all four connecting blocks are fixedly connected to sliders, and the tops of the two adjusting plates are provided with sliding grooves. The surfaces of the four sliders are slidably connected to the interiors of the two sliding grooves.

The interior of the four connecting plates is slidably connected to the surface of the two limiting plates.

[0025] The working principle of this utility model:

[0026] When clamping the cylinder liner, the hydraulic cylinder 501 is activated. The output end of the hydraulic cylinder 501 drives the insert plate 502 to move downward, disengaging the insert plate 502 from the two insert blocks 503. The left and right clamping ends 203 are moved to a suitable position so that they do not obstruct the machining position. During the movement of the left and right clamping ends 203, the two adjusting plates 3 are moved via the left and right connecting blocks 201. During the movement of the two adjusting plates 3, the two insert blocks 503 are moved. The hydraulic cylinder 501 is activated to drive the insert plate 502 upward, inserting the insert plate 502 into the insert blocks 503, restricting the movement of the two adjusting plates 3, thereby allowing the left... With the clamping ends 203 on both sides remaining stable, the drive motor 401 is started. The output end of the drive motor 401 drives the bidirectional screw 402 to rotate. During the rotation of the bidirectional screw 402, it drives the two connecting rods 403 to move to opposite sides. During the movement of the two connecting rods 403, it drives the clamping ends 203 on both sides to move through the connecting blocks 201 on both sides, so that the clamping ends 203 on both sides are disengaged and the cylinder liner is placed between the four clamping ends 203. The drive motor 401 is started to reverse. During the reverse rotation of the drive motor 401, it drives the clamping ends 203 on both sides to move to opposite ends, and clamps and fixes the cylinder liner through the clamping ends 203.
