A preloading device for a gear shaft of an air outlet frame

Abstract

The invention provides a prepressing device of a gear shaft of an air outflow frame. The prepressing device is used for installing the gear shaft into an installation hole of the air outflow frame. The prepressing device comprises a clamping piece used for fixing the air outflow frame, a bottom die arranged opposite to the face where a locating hole is located and a press machine used for driving the clamping piece to move close to the bottom die, wherein the locating hole opposite to the installation hole of the air outflow frame is formed in the clamping piece and the gear shaft is sleeved with the locating hole. In the process of work, the air outflow frame is fixed through the clamping piece, it is guaranteed that the installation hole and the locating hole are oppositely formed, the gear shaft penetrates through the locating hole and is aligned with the installation hole, the other end of the gear shaft abuts against the bottom die, the press machine drives the clamping piece and the bottom die to move close to each other so as to exert pressure on the gear shaft, the gear shaft is installed in the installation hole, and the gear shaft of the air outflow frame is prepressed. According to the prepressing device, the press machine is adopted for exerting pressure, the manual press is prevented, and therefore the labor intensity of operators is effectively reduced.

Description

technical field

[0001] The invention relates to the technical field of air conditioner production, in particular to a preloading device for a gear shaft of an air outlet frame. Background technique

[0002] When the air conditioner glass door cabinet internal unit is assembled online, the air outlet frame needs to be installed with three gear shafts according to the process technical parameters and requirements, and the gear shafts and the holes on the air outlet frame have an interference fit.

[0003] At present, the installation of the gear shaft on the air outlet frame usually requires the operator to manually press or knock the gear shaft into the hole on the air outlet frame to complete the fit. However, manual pressing or knocking on the gear shaft by heavy objects can easily cause deformation of the gear shaft and affect the normal use of the gear shaft. In addition, manual pressing or knocking greatly wastes the operator's labor and increases the operator's time. l...
