Description
Technical field
The utility model relates to a kind of part sectional fixture of automobile air conditioner compressor, and the shaft seal particularly relating to a kind of automobile air conditioner compressor installs shield jig.
Background technology
The power of automobile air conditioner compressor is first passed to driving shaft from clutch, then is passed to swash plate by driving shaft, then be passed to hemisphere, finally to piston, thus makes the converting rotary motion of engine become the reciprocating motion of compressor inside.Wherein driving shaft is that external impetus reaches inner bridge, and the high-pressure oil gas mixture of compressor inside needs sealing in transmittance process, and now shaft seal just serves the sealing function to the driving shaft that runs up, and makes inside and outside isolation.
Shaft seal being installed on compressor front end housing at present, is the axis hole first shaft seal directly put on compressor front end housing, then with gland press-in, finally compresses.On the one hand because the axis of shaft seal and the axis of axis hole can exist certain deviation, affect assembly quality; On the other hand owing to adopting rubber sealing between the axis hole in shaft seal and compressor front end housing, and caulking gum is arranged in shaft seal, therefore shaft seal external diameter is greater than the axis hole aperture on compressor front end housing, load time shaft seal on caulking gum can be enclosed cut by the edge, axis hole upper surface one on compressor front end housing, just can only pinpoint the problems when assembly sealing property detects again after installation, not only have a strong impact on efficiency of assembling, and repair rate is high, greatly improves production cost.
Utility model content
For the problems referred to above; the shaft seal that the problem that the utility model quasi-solution is determined is to provide a kind of automobile air conditioner compressor of simple and reasonable, accurate positioning installs shield jig; not only make shaft seal easy for installation; and available protecting shaft seal; make in its intact axis hole be encased on compressor front end housing; frequency is reprocessed in effective reduction, improves efficiency of assembling, reduces production cost.
For achieving the above object, the utility model is by the following technical solutions: a kind of shaft seal of automobile air conditioner compressor installs shield jig, comprise panel, positioning sleeve, positioning core axle, shaft seal protective sleeve and gland, an installation through hole one is provided with in the middle of described panel, an installation through hole two is provided with in the middle of described positioning sleeve, described positioning sleeve is vertically fixed on described panel by screw, and the center line of the center line of described installation through hole one and described installation through hole two is coincided, described positioning core axle bottom interference is connected in the installation through hole one of described panel, the top of described positioning core axle is tapered, the tapering of described taper is set to 8 ° ~ 8.5 °, the center line of described installation through hole one, the center line of described installation through hole two all coincides with the center line of described positioning core axle, described shaft seal protective sleeve is provided with longitudinal through hole one, the top of described longitudinal through hole one is provided with enlarging, described gland is provided with longitudinal through hole two, described shaft seal protective sleeve and described gland are set on described positioning core axle successively.
As preferably, the tapering of described taper is 8 °.
Effective achievement of the present utility model: the utility model is simple and reasonable; during use; the shaft seal protective sleeve be set on positioning core axle and gland are taken off; first compressor front end housing is navigated in the installation through hole two in positioning sleeve by positioning core axle; then shaft seal protective sleeve is navigated in the axis hole on compressor drive end bearing bracket by positioning core axle; and then shaft seal is set on positioning core axle; making it by tentatively entering in the axis hole on compressor front end housing after shaft seal protective sleeve, finally with gland shaft seal to be pressed into completely in the axis hole on compressor front end housing and to compress.
In this use procedure, owing to being provided with panel, positioning sleeve and positioning core axle, accurate centralized positioning is carried out to the axis hole on compressor front end housing, namely accurate centralized positioning has been carried out to the installation site of shaft seal, not only facilitate the installation of shaft seal, improve efficiency of assembling, and improve assembly quality; Positioning core axle top is tapered, in installation process, serve protective effect to the inwall of shaft seal; Shaft seal protective sleeve is provided with longitudinal through hole one; the top of this longitudinal through hole one is provided with enlarging; in installation process, the outer wall of shaft seal is played a protective role; effectively avoid the caulking gum in shaft seal by the edge, axis hole upper surface one on compressor front end housing enclose cut; thus enable in the intact axis hole be encased on compressor front end housing of shaft seal; frequency is reprocessed in effective reduction, improves efficiency of assembling, reduces production cost.
In sum, the utility model has feature that is simple and reasonable, accurate positioning, not only makes shaft seal easy for installation, and available protecting shaft seal, makes it intactly be encased in axis hole, effectively reduces and reprocess frequency, improve efficiency of assembling, reduce production cost.
