Abstract
This utility model relates to the motor case of a kind of vortex type automobile air conditioner compressor, including the hollow cylindrical for installing motor core, 4 legs it are provided with bottom hollow cylindrical, the bottom outlet installing fixing motor case and the groove being easy to bottom outlet processing it is provided with at leg, groove hollows out bottom outlet top, structure compared to prior art motor casing, 4 legs it are provided with bottom motor case of the present utility model, bottom outlet and groove it is provided with at leg, bottom outlet is carried out tapping and adds man-hour, owing to groove hollows out bottom outlet top, foundry goods deeper portion will not be machined to, internal defect in cast will not be exposed, improve yield rate, can well be arranged on inside compressor firm for motor case in bottom outlet after screw precession processing.
Description
Technical field
This utility model relates to vortex type automobile air conditioner compressor, is specifically related to the motor case of a kind of vortex type automobile air conditioner compressor.
Background technology
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to gases at high pressure, it is most important parts in air-conditioning equipment, wherein, vortex type automobile air conditioner compressor is the one in numerous compressor, and because it has efficiency height, energy consumption is low, vibrate little, the features such as noise is low, simple in construction, are commonly used for automobile refrigerating.In numerous component parts of vortex type automobile air conditioner compressor, motor is arranged on inside motor case, and casing is fixedly mounted on car body with coordinating of screw hole by screw thread.Motor case currently on the market is die casting, the internal structure of die casting built on the sand and tends to have the defects such as pore, when to the bottom outlet tapping of motor case, the defects such as inside are easily dropped out at bottom outlet, and this defect subsequent treatment (such as infiltration) etc. all cannot be remedied, compressor can be affected and normally work.
Utility model content
In order to solve the technical problem easily occurring leakage at the fixing foot of existing motor case, this utility model provides a kind of motor case rational in infrastructure, and concrete technical scheme is as follows:
A kind of motor case of vortex type automobile air conditioner compressor, including the hollow cylindrical for installing motor core, being provided with 4 legs bottom hollow cylindrical, be provided with the bottom outlet installing fixing motor case and the groove being easy to bottom outlet processing at leg, groove hollows out bottom outlet top.
Preferably, described depth of groove is more than bottom outlet aperture, and bottom outlet head exposes completely from groove.
Preferably, described groove die casting is one-body molded.
Preferably, hollow cylindrical is arranged over bottom outlet, and bottom orifice is provided with groove, and groove hollows out the part tapping path of bottom outlet.
The beneficial effects of the utility model: compared to the structure of prior art motor casing, 4 legs it are provided with bottom motor case of the present utility model, bottom outlet and groove it is provided with at leg, bottom outlet is carried out tapping and adds man-hour, owing to groove hollows out bottom outlet top, and do not have the defects such as pore in the certain thickness of die casting surface.Therefore after thread mill drilling, internal defect in cast will not be exposed, not have the defects such as pore, improve yield rate, can well be arranged on inside compressor firm for motor case in the bottom outlet after screw precession processing.

Fig. 4 is cross section view of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described further:
As shown in figures 1-4, a kind of motor case of vortex type automobile air conditioner compressor, including the hollow cylindrical 1 for installing motor core, bottom hollow cylindrical 1, it is provided with 4 legs 2, at leg 2, is provided with the bottom outlet 3 installing fixing motor case and the groove 4 being easy to bottom outlet processing.Man-hour is added when using screw tap that bottom outlet 3 is carried out tapping, can be easily worked to the deeper position of shell casting, because deep part is the most defective, the most easily expose defect, and cause housing to be revealed, in order to avoid this phenomenon, groove 4 hollows out bottom outlet 3 top, and die casting itself is internal can be defective, and surface is the most defective in the range of certain thickness, after increasing groove 4, when thread mill drilling, just will not be worked into cast-internal, internal flaw will not be exposed, do not interfere with use, improve yield rate.
Groove 4 degree of depth is more than bottom outlet 3 aperture, and bottom outlet 3 head exposes completely from groove 4, it is simple to screw tap is machined through, and reduces the processing screw hole impact on casing, it is easy to location installed by screw.Groove 4 is one-body molded with motor case die casting, it addition, concrete, it also is provided with bottom outlet 3 above hollow cylindrical 1, at bottom outlet 3, is provided with groove 4, groove 4 hollows out the part tapping path of bottom outlet 3, it is possible to avoid housing manufacturing deficiency occur.
In a word, motor casing structure of the present utility model is reasonable in design, and screw exposes the probability of internal flaw through the bottom outlet 3 of four legs 3, the fixing motor case that can consolidate, the design of groove 4 when avoiding processing screw thread.
Above content is to combine concrete preferred implementation further detailed description of the utility model; it cannot be assumed that of the present utility model being embodied as is confined to these explanations; for this utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; arbitrarily change bottom outlet 3 and the position of groove 4, all should be considered as belonging to protection domain of the present utility model.
Claims (4)
