Description

Miniature electronic jar

Technical Field

The utility model belongs to the technical field of electronic jar equipment, concretely relates to miniature electronic jar.

Background

The electric cylinder is a novel mechanical execution element for converting the rotary motion of a servo motor into the linear motion of a screw rod, is widely applied to industries such as mechanical automation, medical equipment, military industry, civil construction and the like, has the advantages of high precision, light structure, low noise, wide application range and the like, and has a trend of replacing a hydraulic cylinder and an air cylinder by the electric cylinder. However, the electric cylinder is different from a hydraulic cylinder and an air cylinder which are in fluid transmission, the internal structure of the electric cylinder takes a screw rod as a core transmission part, and the size and the appearance are influenced by the type of the screw rod, so that the electric cylinder is more limited in space size and length than the hydraulic cylinder and the air cylinder, and is particularly satisfactory to use in a narrow space, and therefore a miniature electric cylinder is needed to solve the problems and meet the requirements of people.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a miniature electronic jar to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a miniature electronic jar, includes motor and cylinder body, the motor passes through the rotatory fixed connection of ball screw in shaft coupling and the cylinder body, the cover is equipped with screw-nut on the ball screw, it is equipped with the bearing to be located the cover on the ball screw between shaft coupling and the screw-nut, the one end that ball screw kept away from the bearing is connected with the piston, installs the piston rod in the cavity of piston.

Preferably, the coupling is matched with a coupling seat.

Preferably, the bearing is matched with a bearing seat.

Preferably, a locking nut is sleeved on the ball screw between the coupler and the bearing.

Preferably, a front end cover is connected between the output end of the piston rod and the inner wall of the cylinder body.

Preferably, the motor is fitted with a motor mount.

Preferably, the ball screw has a diameter of 8 mm.

The utility model discloses a technological effect and advantage: this miniature electronic jar, the appearance of miniature electronic jar then compensatied the blank of electric jar in high-precision machining, application, has adopted diameter 8 mm's superfine lead screw to let electric jar size structure break through the limitation in the past, becomes more thin more light shorter little.
