Bolt tightening machine for automobile factory

Abstract

The invention discloses a bolt tightening machine for an automobile factory, and belongs to the technical field of automobile part processing. The machine comprises a shell body and a driving shell, wherein the driving shell is fixedly connected to the bottom of the shell body through screws, a rotating shaft is transversely inserted into the right side wall of the shell body, a sliding sleeve isarranged on the right side of the outer wall of the rotating shaft in a sleeving mode, a sliding block is arranged on the inner wall of the sliding sleeve, a sliding groove is axially formed in the outer wall of the rotating shaft, the sliding block is clamped in the sliding groove, and a tightening outer screw sleeve is connected with the right end of the sliding sleeve. A driving motor and a gear pair are used as a power mechanism and a power transmission mechanism respectively, and power can be transmitted to the rotating shaft to drive the rotating shaft to rotate for action, so that the effect of power transmission is realized; the rotating shaft drives the sliding sleeve and the tightening outer screw sleeve to rotate, and the tightening outer screw sleeve is matched with a bolt to drive the bolt to rotate, so that the tightening effect is realized; and through the arrangement of a return spring, the tightening outer screw sleeve can be elastically supported on the tightened bolt, and thus the machine is suitable for different use conditions.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing, in particular to a bolt tightening machine for automobile factories. Background technique [0002] my country's latest national standard "Terms and Definitions of Vehicles and Trailer Types" (GB / T 3730.1-2001) has the following definition for a vehicle: a non-rail-loaded vehicle driven by power with 4 or more wheels, mainly used Used for: carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purpose. [0003] From the end of the 19th century to the beginning of the 20th century, automobile designers devoted their energy to the development and innovation of automobile mechanical engineering. In the first half of the 20th century, after the basic structure of the car had been invented, car designers began to improve the exterior shape of the car, and successively introduced aerodynamics, fluid mechanics, ergonomics and industrial design (industr...
