Abstract

The invention discloses an electric cylinder with a gas buffer. The electric cylinder comprises an outer pipe, a bearing chamber, a lead screw and a nut mechanism, wherein the bearing chamber is coaxially and fixedly connected to one end of the outer pipe; the lead screw is coaxially arranged in the outer pipe, and one end of the lead screw is rotatably supported in the bearing chamber through a bearing; the nut mechanism is located in the outer pipe and installed on the lead screw in a matched mode; the peripheral direction of the outer edge of the nut mechanism is in sealing contact with the inner wall of the outer pipe; a power pipe coaxially sleeves the other end of the lead screw in a spaced manner; one end of the power pipe is fixedly connected with the nut mechanism, and the other end extends out of the outer pipe; a first waterproof vent plug and a second waterproof vent plug are fixedly arranged on the outer pipe and communicate with an inner cavity of the outer pipe; the first waterproof vent plug and the second waterproof vent plug are both arranged between the zero position and the tail position of the nominal stroke of the electric cylinder, the first waterproof vent plug is arranged close to the tail position, and the second waterproof vent plug is arranged close to the zero position; and when a driving motor drives the lead screw to rotate, the nut mechanism moves in the axial direction of the lead screw.

Description

technical field [0001] The invention belongs to the technical field of electric cylinders, in particular to an electric cylinder with a gas buffer. Background technique [0002] The electric cylinder converts the rotary motion of the motor into linear motion, and at the same time converts the motor's precise speed control, precise revolution control, and precise torque control into precise speed control, precise position control, and precise thrust control; it realizes high-precision linear motion series. New revolutionary product. At present, the buffer device inside the traditional electric cylinder structure is a rubber shock absorber, but the service life of the rubber shock absorber is short. If there are multiple impacts, the rubber shock absorber will break, thus losing the function of shock absorption and buffering. In view of the above reasons, it is necessary to design and adopt a kind of other cushioning form to replace the rubber shock absorber. Contents of th...
