Wherein, a space is arranged between the stripping block and the rotating plate, and a spring is arranged in the space. Spacing nails are uniformly distributed on the material stripping block in the circumferential direction. Corresponding arc-shaped openings are formed between the outer edge of the stripping block and the inner circle of the support sleeve, and a positioning diamond pin is arranged between the two arc-shaped openings. The lever oil cylinders are arranged on the two sides of the rotating plate, and the outer ends of the pressure rods of the lever oil cylinders press one end of the hydraulic pump cylinder body during machining.
The utility model discloses a further improvement scheme is, changes board lower surface center and has flat pit, and flat pit end internal fixation has the connecting cover, the pivot stretches into and fixes in the connecting cover.
According to the scheme, during machining, the pin hole blank at one end of the hydraulic pump cylinder body to be machined is seated on the positioning round pin, and the 5 limit nails of the positioning round pin are respectively propped between the adjacent holes of the 5 holes at the lower end of the hydraulic pump cylinder body blank. Then the outer ends of the pressure rods of the two lever oil cylinders are respectively pressed on the two opposite sides of the upper end of the hydraulic pump cylinder body blank by an additionally arranged controller. And then, processing the blank of the hydraulic pump cylinder body. And finishing the processing. The stripping block 7 will move upwards under the action of the spring, so that the cylinder to be processed is ejected. Compared with the background technology, the whole positioning process does not need manual operation, and the production efficiency can be greatly improved.
