Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0025] Such as Figure 1-2 As shown, a multi-door precision air cylinder proposed by the present invention includes a cylinder barrel 1, a plurality of air cavities are equidistantly arranged in the cylinder barrel 1, a piston 13 is movable in the air cavity at the bottom side, and a piston 13 is movable in the remaining air cavities. A magnetic piston 5 is movable, and a plurality of pistons 13 and the outer circumference of the magnetic piston 5 are uniformly processed with a retaining ring 15, and a spring sleeve 6 is fixed at the tail of each air cavity, and a spring is fixed at the tail of each spring sleeve 6. A spring 19 is arranged between the seat 7, the cir...

Abstract

The invention discloses a multi-gate precision air cylinder. A plurality of air cavities are formed in a cylinder barrel at equal intervals, a piston is movably arranged in the air cavity located on the bottommost side, magnetic pistons are movably arranged in the other air cavities, and elastic check rings are integrally machined on the outer circumferential faces of the multiple pistons and theouter circumferential faces of the magnetic pistons. A spring sleeve is fixed to the tail of each air cavity, a spring seat is fixed to the tail of each spring sleeve, and springs are arranged betweenthe elastic check rings and the corresponding spring seats. A bearing is fixed in each piston, front covers are fixed to the sides, away from the springs, of the magnetic pistons and the pistons, andcustomized connectors are fixed to the other sides of the front covers. Through the arrangement of a first wear-resisting belt and a second wear-resisting belt, the wear resistance is improved; and meanwhile, when the magnetic pistons and the pistons are reset, the precision of butt joint with the springs is improved, and the high pressure resistance is high.

Description

technical field [0001] The invention relates to the technical field of cylinders, in particular to a multi-door precision cylinder. Background technique [0002] A cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. Air expands in the engine cylinders to convert thermal energy into mechanical energy; gas is compressed by pistons in the compressor cylinders to increase its pressure. [0003] The housings of turbines, rotary piston engines, etc. are often also referred to as "cylinders". The application fields of the cylinder: printing (tension control), semiconductor (spot welding machine, chip grinding), automation control, robot and so on. [0004] The cavity in the cylinder block of an internal combustion engine in which the piston is placed. It is the orbit of the piston movement, in which the gas burns and expands, and part of the waste heat of the explosion transmitted by the gas can be dissipated through the cylinder...
