Description

Technical Field

[0001] The utility model relates to the technical field of marine diesel engines, in particular to a horizontal tooling for processing an exhaust pipe of a high-speed engine. Background Art

[0002] A diesel engine is an internal combustion engine that uses diesel as fuel. Its working principle is to compress air to a high temperature in the cylinder, causing the injected diesel to self-ignite, and then the gas expands to do work. Marine diesel engines are used as the power source for ships, among which marine high-speed diesel engines are mainly used for ship power and small and medium-sized high-speed ships. The main feature is that in order to maintain the lightweight design goal, the design features of various parts of high-speed engines are often compact. The exhaust pipe is a part that transports the high-temperature exhaust gas generated during the operation of the high-speed engine. It is responsible for collecting and transporting the exhaust gas from each combustion chamber. Horizontal tooling is required for the processing of high-speed engine exhaust pipes.

[0003] Common horizontal tooling for processing high-speed machine exhaust pipes is usually composed of a tooling base frame, positioning components, clamping components, supporting parts, a rotary drive device, and accessories. The workpiece is first fixed by the positioning component, the clamping component, and the supporting component, and then the workpiece is rotated by the rotary drive device, and the accessories detect the processing status of the workpiece. This is a common horizontal tooling structure and usage method for processing high-speed machine exhaust pipes. Although the traditional horizontal tooling for processing high-speed machine exhaust pipes can complete the processing content of a single station processing surface, it is necessary to remove and shift the overlapping tooling that may interfere when transferring to the next station processing surface. The displacement process is bound to cause the exhaust pipe to move, and the reference surface needs to be calibrated again in the next station processing, resulting in reduced processing quality and reduced production efficiency. For this reason, a horizontal tooling for processing high-speed machine exhaust pipes is proposed. Utility Model Content
