Description

Technical Field

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

[0002] Traditional clamping devices are difficult to clamp and install multiple cylinder liners at once because different diesel engine boxes have different specifications and the distance between cylinder liner grooves is also different.

[0003] CN221582674U discloses a positioning and clamping device for engine cylinder liner processing, relating to the field of cylinder liner clamping technology. It includes a worktable, with a support rod fixedly mounted on the upper surface of the worktable. A top plate is fixedly mounted on the upper end of the support rod, and a second hydraulic cylinder is fixedly mounted on the lower surface of the top plate. A support plate is fixedly mounted on the output end of the hydraulic cylinder. A pressure plate is fixedly mounted on the lower end of each guide rod. A positioning component for limiting the guide rod is provided on the support plate. When the operator pulls the pull plate, the positioning rod can be pulled forward, causing the top of the positioning rod to disengage from the positioning hole. The operator can then slide the mounting plate, causing the pressure plate to slide and adjust the distance between the pressure plates. A return spring returns the positioning rod to its original position within the positioning hole. The device can simultaneously clamp and install multiple cylinder liners and adjust the distance between the pressure plates.

[0004] However, existing technologies cannot quickly clean the outer surface of the cylinder liner before pressing to remove dust and other impurities, thus failing to ensure a tight fit between the cylinder liner and the engine block. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning and clamping device for engine cylinder liner processing, which aims to solve the problem in the existing technology that the outer surface of the cylinder liner cannot be quickly cleaned before clamping to remove dust and other impurities, thus failing to ensure a tight fit between the cylinder liner and the engine block.

[0006] To achieve the above objectives, this utility model provides a positioning and clamping device for machining engine cylinder liners, including a worktable and a clamping body, wherein the clamping body is disposed on the worktable and located on one side of the worktable.

[0007] Also includes cleaning components,

[0008] The cleaning assembly includes a connector, an air pump, a connecting pipe, an air inlet hood, a filter, an air outlet hose, a nozzle, a cleaning component, and a placement component. The connector is fixedly connected to the workbench and located on one side of the workbench. The air pump is fixedly connected to the connector and located on one side of the connector. The connecting pipe is connected to the input end of the air pump and located on one side of the air pump.
