Auxiliary device for tightening force moment of air pump joint

Abstract

The invention discloses an auxiliary device for tightening the force moment of an air pump joint. The auxiliary device comprises a base plate, a supporting plate and a tool frame, wherein the base plate is provided with a plurality of fixing bolt holes which penetrate through the upper and lower surfaces of the base plate, and the base plate is horizontally fixed on an air pump supporting surface through fixing bolts; the lower end of the supporting plate is vertically arranged at one side of the base plate to form an L-shaped bracket; the tool frame comprises clamping slot frames and an arc-shaped clamping plate; the clamping slot frame at each of the two sides is horizontally connected with the upper end of the supporting plate through one end of the clamping slot frame and is provided with a groove; the openings of the grooves of the clamping slot frames at the two sides are arranged oppositely; the two sides of the arc-shaped clamping plate are respectively connected with lower plates of the grooves of the clamping slot frames at the two sides; the front surface of the arc-shaped clamping plate is provided with an arc-shaped clamping slot for clamping an air pump; a gear end of the air pump is upwards clamped inside the grooves of the clamping slot frames at the two sides and the arc-shaped clamping slot in the front surface of the arc-shaped clamping plate, so the air pump does not rotate when the force moment of a charging joint and a discharging joint of the air pump is tightened. The auxiliary device is capable of alleviating the labor intensity of a worker and improving the production efficiency.

Description

technical field [0001] The invention relates to the field of engine assembly, in particular to an auxiliary device for tightening the torque of an air pump joint. Background technique [0002] During the production process, there is no auxiliary device suitable for tightening the torque of the air pump joint when assembling the air pump inlet and exhaust joints. During the assembly process, the air pump needs to be fixed manually. Low and insufficient joint torque, resulting in the failure of air leakage in the intake and exhaust joints. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide an auxiliary device for tightening...
