Hole expanding device for air-conditioner liquid accumulator

Abstract

The invention provides a hole expanding device for an air-conditioner liquid accumulator. The hole expanding device comprises a base; a containing groove is formed in the base, clamping blocks are arranged on the two sides of the containing groove, and a pressing air cylinder is arranged above the containing groove; the lower end of the pressing air cylinder is provided with a hole expanding block, and one side of the hole expanding block is provided with a position sensor which is electrically connected with the pressing air cylinder; the base is provided with starting switches, the number of the starting switches is two, the two starting switches are located on the two sides of the upper end face of the base, and the two starting switches are connected in series to control the pressing air cylinder to work. A steel pipe is fixed through the containing groove and the clamping blocks so that manual positioning is avoided; moreover, the position sensor is arranged for detecting the pressing amount of the pressing air cylinder, and accordingly material waste caused by excessive pressure of the pressing air cylinder is reduced; an operator needs to press the two starting switches at the same time with the two hands to enable the hole expanding device to start to work by arranging the two starting switches, so that potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of air-conditioner liquid storage manufacturing, in particular to an air-conditioning liquid storage hole reaming device for reaming a steel pipe of the liquid storage device. Background technique [0002] When making the air-conditioning reservoir, it is necessary to ream the steel pipe that has been cut into sections, and then perform the hemming process on it. Therefore, a reaming device is required when reaming the steel pipe. The current reaming device is an ordinary press machine, and a reaming head is installed on the press head of the press machine to ream the steel pipe. However, the above method requires manual positioning of the steel pipe to prevent the steel pipe from being damaged due to the deflection of the reaming block during reaming. , and it is difficult to control the amount of pressure when using a general press machine, and it is easy to cause damage to the steel pipe due to excessive pressure d...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide an air-conditioning accumulator hole reaming device for reaming the steel pipe of the accumulator. The steel pipe is fixed by placing grooves and clamping blocks, avoiding manual positioning, and the pressure is controlled by setting a position sensor. The down pressure of the cylinder is detected to prevent excessive down pressure, which solves the problem of manual positioning and easy damage to the steel pipe when reaming the steel pipe
