Automatic expanding connection device at engine oil filling port

Abstract

The invention provides an automatic expanding connection device at an engine oil filling port. The automatic expanding connection device comprises a case. An expanding connection die is arranged on the case which is internally provided with a pneumatic power system. The expanding connection die is connected with the pneumatic power system through a lifting cylinder and composed of a flange plate fixing part and an engine oil filling port expanding connection part. The engine oil filling port expanding connection part is arranged in the center of the flange plate fixing part and composed of a plurality of expanding connection petals and an expanding connection shaft. An expanding connection protrusion is arranged outside each expanding connection petal. A circle is defined by the expanding connection petals in a surrounded mode. The expanding connection shaft is located in the center of the circle defined by the expanding connection petals in the surrounded mode and connected with the lifting cylinder. A foot switch is arranged outside the case. The pneumatic power system is controlled by the foot switch. According to the automatic expanding connection device at the engine oil filling port, premise requirements for the brazing process are met; the automatic expanding connection device is convenient and efficient to use and has multiple functions by means of electric control; and the automatic expanding connection device is suitable for automatic expanding connection for multiple types of products.

Description

technical field [0001] The invention belongs to the field of workpiece processing, in particular to an automatic expansion device for a machine oil port. Background technique [0002] At present, in the processing of oil pipes and flanges, in order to meet the prerequisite requirements of the brazing process, it is necessary to process multiple rising points at the oil filling port. At present, this operation can only be done manually, which is time-consuming and laborious, and the processing costs are high. The spots are uneven, which affects the quality of the product and is not conducive to the improvement of production efficiency. Therefore, there is an urgent need for a kind of automatic expansion device for oil filling port now. Contents of the invention [0003] The invention proposes an automatic expansion device for the oil filling port, which solves the problems of time-consuming and labor-intensive manual expansion and uneven processing of the expansion point i...
