Planet differential type automatic moment varying electric control device

Abstract

The invention relates to a planet differential type automatic moment varying electric control device. The planet differential type automatic moment varying electric control device solves the problemsthat an existing automobile part automatic frock clamp is complex in structure, and inconvenient to maintain or replace later. The planet differential type automatic moment varying electric control device comprises a fixing bottom seat, a micro motor, a planet wheel assembly, a thread differential motion assembly and a pressure sensor, wherein the planet wheel assembly comprises a sun wheel, an axle type planet carrier and planet wheels, the thread differential motion assembly comprises a top cover, a differential thread sleeve and a differential thread inner gear ring, the sun wheel is connected with an output shaft of the micro motor, the planet wheels are arranged in the peripheral direction of the sun wheel, and respectively engaged with the sun wheel and the differential thread innergear ring, inner teeth of the differential thread inner gear ring are engaged with the planet wheels, an external thread at the top end of the differential thread inner gear ring is engaged with the top cover arranged on the periphery of the differential thread inner gear ring and the axle type planet carrier, an external thread at the bottom end of the differential thread inner gear ring is engaged with the differential thread sleeve, the axle type planet carrier is connected with the top cover through a thread, the top end of the axle type planet carrier stretches out of the top cover, and the pressure sensor is arranged at the bottom end of the differential thread sleeve.

Description

technical field [0001] The invention relates to electric control equipment, in particular to a planetary differential self-torque electric control device. Background technique [0002] With the development of informatization and automation, electronic control equipment (or devices) have been widely used in various industries. In the automotive industry, since most of its parts and components have dimensions <500mm, the size of the corresponding tooling execution components (positioning, auxiliary support, clamping, etc.) cannot be too large, and the size requirements limit the electronic control equipment (or device) ) developments in this field. [0003] At present, most of the automatic tooling fixtures for auto parts are pneumatic or hydraulic structures, and their structures are generally complicated and inconvenient for later maintenance and modification. Therefore, there is an urgent need for an electronic control device structure that is small in size, fast in ex...
