Abstract

The invention discloses a square pistol oil cylinder system with a valve needle positioning function. The square pistol oil cylinder system comprises an oil cylinder body, a conical oil cylinder cap, a square piston and a valve needle, wherein a square groove is formed in the oil cylinder body; the square piston is glidingly arranged in the square groove; a piston handle is fixed on the square piston; the conical oil cylinder cap is fixed on the oil cylinder body and covers the square groove; a piston handle through hole which is matched with the piston handle is formed in the conical oil cylinder cap; the piston handle can glidingly penetrate through the piston handle through hole; the piston handle is in clearance fit with the piston handle through hole; a T-shaped groove is formed in the end surface, penetrating out from the piston handle through hole, of the piston handle; and one end of the valve needle is arranged in the T-shaped groove. Through above manner, the valve needle cannot rotate, the piston and valve needle move smoothly, and a piston assembly moves stably.

Description

technical field [0001] The invention relates to the field of oil cylinders, in particular to a square piston oil cylinder system capable of positioning valve needles. Background technique [0002] In the prior art, the oil cylinder is composed of an oil cylinder body, an oil cylinder head, a piston, and a valve needle. Since the valve needle and the piston are all circular structures, the valve needle will rotate during the movement, and the valve needle cannot be positioned when it needs to be positioned, and the offset positioning is added. When the pin is used, the positioning pin and the piston are easily stuck, and the system stability is poor. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a square piston oil cylinder system that can position the valve needle. Component movement is stable. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present inve...
