[0036] like image 3 Shown, design raised cylinder intubation annular band (21) in the middle of the inner and outer circle of big end of stepped cylinder insert (2), design the raised L-shaped tube annular band (22) at L-shaped tube (11) , the small end of the cylinder cannula (2) is pressed into the cylinder suction hole (31) with interference, the outer circle of the cylinder cannula ring (21) and the inner circle of the connecting pipe (41) have a clearance fit, and the radius clearance is 0.05~ 0.1 mm, the outer gap (24) of the cylinder cannula is designed as a reasonable welding gap, and its radial gap is 0.10-0.3 mm. The outer circle of the L-shaped pipe annular belt (22) is matched with the inner circle of the cylinder intubation pipe (2), the radial clearance is 0.05-0.1mm, and the outer clearance of the L-shaped pipe (23) is designed as a reasonable welding clearance, and the radial clearance is 0.10~0.3mm.

[0040] like Figure 10 Shown: the clearance fit between the cylinder intubation tube (2) and the L-shaped pipe (11) and the connecting pipe (41) and the distribution of the annular band are the same as in the specific embodiment 1, the difference is that the inner annular band of the cylinder intubation tube (23) extends to the cylinder side with the outer annular band (24) of the cylinder intubation to each part hole or the excircle end, and guarantees the structure of the brazing gap. This design can bring two advantages. On the one hand, the processing and manufacturing are relatively simple; on the other hand, it is more conducive to ensuring the welding between the cylinder insert (2) and the L-shaped pipe (11) and the connecting pipe (41). Uniform distribution of gaps. In addition, the cylinder intubation pipe (2), the connecting pipe (41), and the L-shaped pipe (11) are all made of copper-plated steel on the surface.

[0043] like Figure 14 As shown, since the L-shaped pipe (11) is inserted into the cylinder insert (2), it is much easier than the cylinder insert (2) to be pressed into the cylinder suction hole (31) through the inner hole of the connecting pipe (41), and welding The gap is relatively easy to reach evenly, so also can not produce the protruding annulus on the inner circle of the large end of the cylinder intubation pipe (2) or the outer circle of the L-shaped pipe (11). Only produce the protruding cylinder intubation annular band (21) on the outer circle of the cylinder intubation (2), the outer circle of the cylinder intubation annular band (21) fits with the inner hole clearance of the connecting pipe (41), and its radius The gap is 0.05 ~ 0.1mm, the outer gap (24) of the cylinder cannula is designed as a reasonable welding gap, the radius gap is 0.10 ~ 0.3mm, the distance between the L-shaped tube (11) and the inner hole of the cylinder cannula (2) It is designed to be a ...

Abstract

The invention relates to a connecting structure of a fully-closed compressor suction pipe, wherein gaps of welding seams are evenly distributed, which are guaranteed through a raised girdle is designed on a welding gap position of a connecting pipe, a cylinder inserting pipe and an L-shaped pipe which are arranged on a closed shell or is designed on the welding gap position between the connecting pipe and the cylinder inserting pipe. When a connecting mechanism of the fully-closed compressor suction pipe is welded, a solenoid whose two ends are an U shape in a same rotating direction is used, and a high frequency induction welding of an induction coil of a soft magnetic material is plugged between the U shapes which are arranged on the two sides. When welding, an U-shaped open of the U-shaped induction coil is aimed to the outer circle of the connecting pipe to achieve the circumferential weld of the three. The connecting mechanism of the fully-closed compressor suction pipe is capable of increasing the welding performance, achieving the automation or the semi-automation of welding, increasing the productivity effect, and saving produce cost.

Description
