Dotting positioning device for assembling an air conditioning compressor liquid storage device steel connecting pipe and a barrel

Abstract

The invention relates to the manufacturing field of liquid storage devices for air conditioning compressors, in particular to a dotting positioning device for assembling an air conditioning compressorliquid storage device steel connecting pipe and a barrel. The dotting positioning device comprises a machine frame, a die clamping component, a power mechanism, a dotting and punching mechanism and acontrol component; the die clamping component is a mold core fixedly arranged on a connecting bottom plate, the power mechanism uses an air cylinder for driving, the air cylinder is fixed to an air cylinder fixing plate, the connecting bottom plate and the air cylinder fixing plate are arranged in parallel, the dotting and punching mechanism comprises a cover die arranged on the outer side of a supporting plate and an inclined device guide plate on the inner side, an inclined device is in sliding fit with the inclined device guide plate, and the control component is used for controlling the air cylinder to be connected with an external air source through an electromagnetic valve. In order to change products with different specifications, only a cylinder stroke adjusting nut needs to be adjusted, a corresponding cylinder positioning sleeve and a steel connecting pipe positioning mandrel are replaced, a punching pin does not need to be adjusted, and changing efficiency is high.

Description

technical field [0001] The invention relates to the field of manufacturing liquid accumulator products for air-conditioning compressors, in particular to a dot fixing device used when assembling a steel connecting pipe of an air-conditioning compressor liquid accumulator and a cylinder body. Background technique [0002] During the production and processing process of the liquid receiver for air-conditioning compressors, including the process of assembling and docking the steel connecting pipe and the cylinder body, a spotting and fixing device is required. The dotting and positioning device currently used is a hydraulic system, including three hydraulic cylinders, which are evenly distributed at 360°. The hydraulic cylinders are controlled to move axially through solenoid valves respectively, and the metal cylinder is dotted, that is, impact pressure is applied on three points. , forming three point-shaped depressions to realize the positioning or connection between the met...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the above-mentioned prior art are: 1. The axial movement of the three hydraulic cylinders is controlled by three solenoid valves, and the operating speed and displacement of the main shafts of the hydraulic cylinders are not synchronized, resulting in a serious extrusion deformation at one point when the cylinder is extruded. The gap at the matching position becomes smaller, and when the other two points are re-extruded, the cylinder is elliptical and deformed, which is not concentric with the steel pipe, and the gap is uneven; 2. The drive response speed of the oil cylinder is slow and the production efficiency is low; 3. The three extrusion heads pass through the thread It is connected and fixed on 3 different hydraulic cylinders. It is necessary to re-adjust the length of 3 punch needles for the cylinder with a small outer diameter. The adjustment is difficult and the consistency of the dotting depth is poor.
