Problems solved by technology

[0002] Due to the complex structure of the existing electric push rod, there are high requirements for the precision of parts processing and installation
During assembly, workers cannot accurately guarantee the installation accuracy, so that the electric push rod often fails to meet the design requirements
Especially for high-thrust electric push rods, problems such as low stability and high noise are caused by various precision problems.
In particular, the pressure sensor is mostly external, and it is easy to cause damage due to uncertain factors in actual production, and it is not compact enough.

Abstract

The invention discloses a high-thrust servo electric push rod with a built-in pressure sensor. The cylinder barrel and the front end cover are connected and cover the outside, the hollow pipe and theball screw nut are fixedly arranged, the ball screw is connected with the ball screw nut, the bearing is arranged on the ball screw, the connecting piece is arranged on the bearing, the pressure sensor is fixed to the connecting piece and located in the cylinder barrel, the motor plate and the pressure sensor are fixedly arranged, the driven wheel is arranged on the ball screw, the driving wheel is arranged on the motor, the driving wheel and the driven wheel are connected through a belt, and the cover body covers the end portion. The transmission mode is optimized, an original coupler is changed into belt sensing, the mechanism is more compact, rigid impact is reduced, noise is reduced, the service life is prolonged, meanwhile, the installation position of the pressure sensor is internally arranged, data feedback is more accurate, and the effect of protecting the pressure sensor is achieved.

Description

technical field [0001] The invention relates to the technical field of electric push rods, in particular to a servo electric push rod with a built-in pressure sensor for high thrust. Background technique [0002] Due to the complex structure of the existing electric push rod, there are high requirements on the precision of parts processing and installation precision. During assembly, workers cannot accurately guarantee the installation accuracy, so that the electric push rod often fails to meet the design and use requirements. Especially for high-thrust electric push rods, problems such as low stability and high noise occur due to various precision problems. In particular, the pressure sensor is mostly external, and it is easy to cause damage due to uncertain factors in actual production, and it is not compact enough. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a servo electric push rod with a built-in pre...
