Description

Technical Field

[0001] The utility model relates to the technical field of oil pan processing, and particularly relates to an oil pan positioning tooling. Background Technique

[0002] As is well known, the oil pan, also known as the oil sump, is an important part of the engine lubrication system. Its main functions are to store the engine oil, seal the engine together with the crankcase to prevent external impurities from entering, and collect and store the lubricating oil flowing back from the engine friction surfaces, which helps with heat dissipation and prevents the lubricating oil from oxidizing. During the processing of the oil pan, positioning tooling is required.

[0003] Chinese Utility Model Publication No. CN218874277U discloses an oil pan positioning tooling, which includes: a rotating base; a bottom plate rotatably connected to the rotating base; a positioning assembly including an inclined positioning table and a vertical positioning plate fixed on the positioning plate. The inclined positioning table matches the left bottom surface of the oil pan, and the vertical positioning plate has a contour surface that matches the bottom contour of the arc panel on the side of the oil pan; a pressing assembly having a plurality of pressing plates for pressing on the end face of the oil pan.

[0004] This device starts the welding work of the oil pan, but the spinning cylinder and the pad of this device are fixedly arranged. When the staff welds to the part where the spinning cylinder coincides with the oil pan, due to being blocked by the spinning cylinder, it is not convenient to weld this coincident part. It is necessary to side the welding instrument and extend it into the interval between the spinning cylinder and the oil pan to weld the oil pan, which increases the welding time, and such welding is relatively inconvenient and the welding efficiency is not high, and there is still room for improvement.
