Abstract
The utility model relates to an upper flange for a rotary compressor, which is provided with a flange body, wherein the flange body is provided with a shaft hole for penetrating a compressor crankshaft, the outer side wall of the flange body is evenly provided with a plurality of machine legs, the outer side wall of the flange body is also provided with a suction hole, and the machine legs, the suction hole and the flange body are cast and formed into an integrated structure; the upper flange reduces the forming process and the welding process of related parts, also reduces related parts and components and can reduce the manufacturing cost of the compressor.
Description
Technical Field
The utility model belongs to the technical field of compressor parts technique and specifically relates to a rotary compressor uses upper flange.
Background
The existing rotary compressor usually sleeves a stator in a shell, a pump body is welded on the shell through an upper flange in a spot welding mode, a machine leg is welded on the shell in an electric resistance welding mode, and a suction hole is also welded on the shell through a copper pipe.
The above-mentioned method is complicated in structure and has many problems: the pump body is connected with the shell in a spot welding mode, so that the connection strength is insufficient, and poor concentricity of the stator and the rotor is easily caused; the machine leg is usually formed by punching a hot rolled steel plate with the thickness of 2.0-3.0, and is welded on the shell in a resistance welding mode, so that the forming is difficult, the connection strength is insufficient, and the vibration of the compressor is easy to be large; the air suction hole is welded on the shell through a copper pipe, and the shell is difficult to manufacture; the weld joint is prone to leakage.
Disclosure of Invention
The utility model aims at providing a rotary compressor uses last flange to above-mentioned condition, should go up the flange and reduced the forming process and the welding process of relevant part, also reduced relevant spare part, can reduce the compressor cost of manufacture.
The utility model has the following concrete scheme: the utility model provides a rotary compressor uses upper flange, has the flange body, is equipped with the shaft hole that is used for wearing to adorn compressor crankshaft on the flange body, the equipartition has a plurality of machine foot on the lateral wall of flange body, still is equipped with the suction hole on the lateral wall of flange body, machine foot, suction hole and flange body three cast the shaping formula structure as an organic whole together.
Further, in the utility model discloses in the quantity of undercarriage is 3, and the bottom of every undercarriage all is equipped with the strengthening rib.
Further, in the utility model discloses in the outer fringe of flange body upwards extends and is equipped with the lantern ring, and the outer fringe downwardly extending of flange body is equipped with down the lantern ring.
Further, in the utility model discloses in it connects to adopt the mode of girth welding to weld between the casing of the upper sleeve ring, lower lantern ring and rotary compressor.
The utility model discloses produced technological effect:
1. the utility model discloses well chassis and the whole casting of flange body: compared with the structure that the machine legs are directly welded on the outer wall of the shell, the structure has higher strength, does not have the risk of falling off of the machine legs, can ensure that the three machine legs are arranged on the same plane, and can reduce the vibration of the compressor; in addition, the molding process and the welding process of the machine legs are reduced, parts are also reduced, and the manufacturing cost of the compressor can be reduced.
2. Integrally casting the air suction hole and the upper flange: compared with the suction hole, the structure can better ensure the position degree of the suction hole in a copper pipe welding mode, and the risk of leakage at the joint of the suction hole can be avoided. The welding process and the parts are reduced, and the cost of the compressor is reduced.
3. The utility model discloses an go up flange and casing and carry out the girth joint, this is higher than last flange and casing spot welding mode welding strength, and welding defect discerns more easily, is difficult to take place the condition of rosin joint, and the welding seam is even moreover. The spot welding mode needs 3 or 6 solder joints to weld simultaneously, otherwise easily causes the welding department shrink deformation inconsistent, leads to stator rotor concentricity to be poor. The girth welding mode has the advantages of high welding efficiency, short time, uniform welding seam and difficulty in causing poor concentricity of the stator and the rotor due to welding deformation. In addition, a special welding device is required to be adopted in a spot welding mode, and the girth welding can share one welding machine with the girth welding of the upper shell cover and the lower shell cover, so that the investment of the device is saved.

Detailed Description
Referring to the figure 1, the utility model relates to a rotary compressor uses upper flange has flange body 1, is equipped with the shaft hole 2 that is used for wearing dress compressor crankshaft on the flange body, the equipartition has a plurality of machine foot 6 on the lateral wall of flange body, still is equipped with suction hole 3 on the lateral wall of flange body, machine foot, suction hole and flange body three cast the shaping formula structure as an organic whole together.
Further, the number of the machine legs in the embodiment is 3, and the bottom of each machine leg is provided with a reinforcing rib 5.
Further, in this embodiment, the outer edge of the flange body extends upward to form an upper collar 7, and the outer edge of the flange body extends downward to form a lower collar 4.
Further, in this embodiment, the upper and lower collars and the casing of the rotary compressor are connected by ring welding.
The utility model discloses a go up the flange body circumference of flange and outwards extend, form 3 evenly arranged's machine legs. The bottom of the machine leg is provided with a reinforcing rib; an upper lantern ring extends upwards from the outer edge of the flange body and is in girth welding with the shell; the outer edge of the flange body extends downwards to form a lower lantern ring, and is welded with the lower shell cover in a ring welding mode; in specific casting construction, the suction holes are designed on the lower extension section of the flange body, namely the side wall of the lower lantern ring, and the specific size of the downward extension is calculated according to the design requirement; the suction holes in the flange body are staggered with the machine legs, and the lower portion of the flange body is originally designed to have a section of length extending downwards for the arrangement of the suction holes.
Fig. 2 is a schematic diagram of the present invention applied to a rotary compressor, and the relevant components are described with reference to the drawings.
