Abstract
The utility model provides a no leakage connecting structure for a compressor pump and a casing body, which comprises a compressor casing body and an upper bearing of a fixed rotating shaft, wherein inner surrounding walls of contact parts of the casing body and the upper bearing are provided with a plurality of sunken holes, and the position of the upper bearing, which corresponds to the sunken holes, is provided with the other corresponding sunken hole of which the hole diameter is equal to that of each sunken hole. Spring pins are arranged in all the sunken holes, and the end surface of each spring pin is a spherical surface. The utility model has the advantages that the connecting structure for a compressor pump and a casing body which is connected by the spring pins in order to realize no pollution, no deformation and no leakage. A cup head pin in the connecting structure is made of metal with a large thermal expansion coefficient, and the metal has a definite intensity. The compressor can be tightly connected with the casing body along with the increase of temperature when operated. The utility model overcomes various defects of previous welding connection, and improves the quality of the compressor.
Description
Technical field
The utility model relates to a kind of compressor pump and the leak free linkage structure of housing.
Background technique
In general, compressor is a kind of machine of compressed fluid.This compressor is by the seal container with certain inner space, is installed in the electromechanical part that can produce driving force in the seal container and can utilizes the driving force of electromechanical part and the compression mechanical portion of compressed fluid constitutes.Fig. 1 is the rotary compressor longitudinal construction sectional view of prior art.As shown in Figure 1, the seal container of this prior art rotary compressor equidistantly is formed with the cylindrical housing 1 of three welding holes and loam cake and lower cover by the bottom along its circumference and constitutes.One side of shell 1 is provided with the refrigerant import, and the center portion of loam cake then is provided with refrigerant exit.The electromechanical part on seal container top mainly by be fixed on cylindrical housing 1 inwall stator and the center of stator and can by and stator between the rotor that is rotated of electromagnetic action form.The compression mechanical portion that is positioned at the seal container bottom then mainly comprises cylinder and is installed in the upper bearing and the lower bearing of cylinder upper and lower end face respectively.Bent axle runs through the center of rotor and cylinder, and it can together rotate with rotor, thereby the rotating force that electromechanical part produces can be passed to compression mechanical portion.The bottom of bent axle is formed with eccentric part, the outside of eccentric part then be with can be rotated in the inside cavity of cylinder and compressible refrigerant roll ring.Because the center of gravity of rolling ring does not overlap with the rotating center of bent axle, thus the power energy imbalance can appear during high speed rotating when bent axle in compressor, thus become the vibrative main cause of compressor.To load onto equilibrium block and come trimming moment in order to address this problem usually to add in the upper end portion of rotor.But there is following point in the rotary compressor of this prior art: compression mechanical portion is to adopt three spot welding connections by three welding holes that form on shell 1 peripheral wall shell 1 and upper bearing 2 directly to be welded together, because the input of the welding heat of this connecting means is bigger, thereby upper bearing 2 and cylinder easily produce thermal distortion, thereby might cause problems such as coolant leakage and moving element friction, therefore can influence the performance of compressor.In addition, this welding method also is easy to make welding slag to remain in the inside of compressor and influence its life-span, and welding process also can cause certain pollution to environment.Currently used three spot welding connections connect compressor pump and shell, are easy to generate leakage, and are easy to generate thermal distortion and welding slag.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of compressor pump and the leak free linkage structure of housing, by adopting the Placement of spring pin, realize that compressor pump is pollution-free with being connected of housing, do not have distortion, do not have and leak.
For achieving the above object, the technical solution adopted in the utility model provides a kind of compressor pump and the leak free linkage structure of housing, include compressor housing, the fixing upper bearing (metal) of running shaft, wherein: the inner circle wall of described housing and described upper bearing (metal) contact position is provided with a plurality of pit-holes, the position of the described upper bearing (metal) corresponding with described pit-holes is provided with corresponding another pit-holes, described pit-holes and another pit-holes are isometrical, are installed with spring pin in described two pit-holes.
The end face of described spring pin is a spherical.
Effect of the present utility model is to utilize spring pin to connect the linkage structure of compressor pump and housing, realized pollution-free, do not have distortion and do not have leakage.Cup head pin in the linkage structure adopts the bigger metal manufacturing of thermal expansion coefficient, and certain intensity is arranged.In compressor operation, can more closely be connected with housing along with the increase of temperature.Change original many disadvantages that is welded to connect, improved the quality of compressor.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated compressor pump of the present invention and the leak free linkage structure of housing.
Shown in Fig. 2,3, the leak free linkage structure of compressor pump of the present invention and housing is to include compressor housing, the fixing upper bearing (metal) of running shaft, described housing 1 is provided with a plurality of pit-holes 4 with the inner circle wall of described upper bearing (metal) 2 contact position, the position of the described upper bearing (metal) 2 corresponding with described pit-holes 4 is provided with corresponding pit-holes 5, described pit-holes 4 and pit-holes 5 are isometrical, be installed with spring pin 6 in described pit-holes 4 and pit-holes 5, the end face of described spring pin 6 is a spherical.
Compressor pump of the present invention is achieved in that with the leak free linkage structure of housing and utilizes spring pin 6 to carry out being connected compressor pump and housing are leak free.At first housing 1 inner circle wall equal intervals process three pit-holes 4, the position of the described upper bearing (metal) 2 corresponding with described pit-holes 4 is provided with corresponding pit-holes 5 that is equal to diameter, utilize anchor clamps to be encased in the housing 1 main bearing 2 that is pre-assembled and the connecting body of spring pin 6, main bearing 2 utilizes interference fit to assemble with housing 1, can not tremble to guarantee housing 1 and main bearing 2.Described pit-holes also can be that symmetry processes on housing 1 inner circle wall, and the position of described upper bearing (metal) 2 is provided with corresponding pit-holes that is equal to diameter.The end face of described spring pin 6 is the cup head pin of spherical, adopts the bigger metallic material manufacturing of thermal expansion coefficient, and certain intensity is arranged.Can more closely be connected with housing in compressor operation along with the increase of temperature, can not occur as the many disadvantages of welding procedure in the past.
