Abstract
Provided is an aluminium crankcase of an air compressor. A bearing seat connection port is formed in one side of an aluminium case body, air cylinder connection ports are formed in two sides adjacent to the bearing seat connection port, and a plurality of screw holes are formed in the peripheral edge of the bearing seat connection port and the peripheral edges of the air cylinder connection ports. The aluminium crankcase of the air compressor is characterized in that the inner wall of the aluminium case body corresponding to the screw holes is provided with protrusions, the screw holes are made to be blind holes, glue does not need to be coated on screws and the screw holes in an assembling process, sealing performance of the aluminium case body is good, oil leakage cannot occur, and improvements of production efficiency and reduction of cost are facilitated. The aluminium crankcase of the air compressor is further characterized in that an oil gathering groove is arranged on the bottom portion of the aluminium case body and is communicated to an oil discharge outlet, and lubricating oil in the crankcase can be discharged through the oil discharge outlet conveniently.
Description
Technical field
The utility model belongs to the air compressor technical field, specifically relates to a kind of aluminium crankcase of air compressor.
Background technique
In the prior art, the aluminium crankcase bottom of air compressor is not provided with the oil-collecting groove, and the lubricant oil in the crankcase can not be discharged fully; The screw hole of aluminium crankcase upper bearing bracket connection mouth and cylinder connection mouth periphery is through hole, must be on screw and screw hole during assembling spreading glue, overflow from screw hole to avoid lubricant oil, operation is more tired; The unavoidable glue in permanent back service time is aging besides, and sealing effect descends, and lubricating oil still can overflow from screw hole.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of aluminium crankcase of air compressor is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of aluminium crankcase of air compressor, comprise the aluminium casing, one side of aluminium casing is provided with the bearing support connection mouth, adjacent both sides with the bearing support connection mouth are provided with the cylinder connection mouth, bearing support connection mouth and cylinder connection mouth periphery are provided with several screw holes, the inwall that it is characterized in that the corresponding aluminium casing in described screw hole place is provided with projection, makes screw hole become blind hole; Described aluminium bottom half is provided with an oil-collecting groove, and the oil-collecting groove is communicated to oil drain out.
The utility model is designed to blind hole with screw hole, need not spreading glue on screw and screw hole during assembling, and the sealability of aluminium casing is better, can leakage of oil yet, help enhancing productivity and reducing cost; Set up an oil-collecting groove at the aluminium bottom half, can must discharge the lubricant oil in the crankcase is very convenient by oil drain out.Therefore the utlity model has characteristics such as simple in structure, reasonable in design.
Description of drawings
Fig. 1 is a kind of main TV structure schematic representation of the present utility model;
Fig. 2 is a kind of side-looking structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1 ~ 2, one side of the utility model aluminium casing 1 is provided with bearing support connection mouth 7, be provided with cylinder connection mouth 2 with bearing support connection mouth 7 adjacent both sides, bearing support connection mouth 7 and cylinder connection mouth 2 peripheries are provided with several screw holes 3, one of improvement is to be provided with projection 4 on the inwall of the corresponding aluminium casing in screw hole 3 places, make screw hole become blind hole, need not spreading glue on screw and screw hole during assembling, the sealability of aluminium casing is better, can leakage of oil yet, help enhancing productivity and reducing cost; Two of improvement is that aluminium casing 1 bottom is provided with an oil-collecting groove 5, and oil-collecting groove 5 is communicated to oil drain out 6, can must discharge the lubricant oil in the crankcase is very convenient by oil drain out 6.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
