Description

Technical Field

[0001] The present invention is used in the field of compressors, and particularly relates to a compressor bracket, a compressor, and a refrigeration device. Background Art

[0002] A refrigerator compressor generally includes a housing and a core. The core is suspended inside the housing by a support spring. The core generally includes a stator component and a rotor component of a motor, a cylinder block, a crankshaft, a connecting rod, a piston, a piston pin, a cylinder head component, etc. The core is connected to the lower housing component through an inner exhaust pipe to form an exhaust passage. The inner exhaust pipe is made of a metal pipe. When the compressor encounters severe bumps during transportation, the inner exhaust pipe may break under the action of bending stress. Therefore, the gap between the core and the housing of the compressor is usually controlled within a relatively small range, such as 3.0 - 5.5 mm. Generally, a plurality of limit points are provided on the cylinder block, including a plurality of horizontal limit points and a plurality of vertical limit points. Generally, the cylinder block is made by casting gray iron and is provided with a plurality of stator legs. Currently, there are three common structures: four stator legs, three stator legs, and two stator legs. The cylinder block structure is heavy, the processing technology is complex, the material cost is high, the processing cost is high, and at the same time, it results in a heavy compressor. Generally, the stator is fixed to the stator legs of the cylinder block by stator screws. Generally, the cylinder head component is fixed to the end of the cylinder hole of the cast iron cylinder block by four screws. In order to meet different exhaust volume requirements, the cylinder block needs to arrange and combine many different cylinder hole diameters and shaft hole diameters, resulting in a large number of cylinder block models, which is not conducive to production management. At the same time, because the shaft hole and cylinder hole of the cylinder block are processed on an integral gray iron casting, large special machine tools are required for processing, with large investment and not conducive to design optimization and change. In order to fix the stator to the stator legs of the cylinder block, stator screw mounting holes are usually provided on the stator punching sheet, so the length and width dimensions of the stator punching sheet become larger, greatly increasing the quota of the stator punching sheet and increasing the material cost.

[0032] Among them, Figure 1 a reference direction coordinate system of the embodiment of the present invention is given. The following combines Figure 1 the directions shown to describe the embodiments of the present invention.

[0033] See Figure 1 、 Figure 2, embodiments of the present invention provide a compressor bracket. The compressor bracket 100 is formed by stamping and bending a thin-walled material. In some embodiments, the compressor bracket 100 is formed by bending a metal plate, for example, made of cold-rolled sheet or pickled sheet, and the material thickness is 1.0 - 4.0 mm. The compressor bracket 100 extends forward from the crankshaft mounting portion 101 to the cylinder head component mounting portion 102. The crankshaft mounting portion 101 is provided with a shaft hole 103 opened along the height direction. The cylinder head component mounting portion 102 is provided with a first support arm 104 and a second support arm 105 extending upward along the height direction. A positioning groove 106 for installing the cylinder liner 200 is formed at the top of the compressor bracket 100 between the first support arm 104 and the second support arm 105. The top of the positioning groove 106 has an opening to facilitate the installation of the cylinder liner 200 and realize the positioning of the cylinder liner 200 in multiple directions. The top of the first support arm 104 is provided with a first limiting arm 107 extending backward, and the top of the second support arm 105 is provided with a second limiting arm 108 extending backward.

[0034] In the technical solution of the present invention, the compressor bracket 100 has a crankshaft mounting portion 101 and a cylinder head component mounting portion 102. Among them, the cylinder head component mounting portion 102 forms a positioning groove 106 for installing the cylinder liner 200 through the first support arm 104 and the second support arm 105. The present invention uses the compressor bracket 100 to replace the cylinder block. Taking the compressor bracket 100 as a bridge, the cylinder head component, moving parts such as the crankshaft, stator component, rotor component, etc. are connected into a core component, greatly reducing the compressor parts and processing procedures; at the same time, components such as an independent cylinder liner 200 can be used in cooperation, making the part processing simple and the production arrangement flexible. In this embodiment, the compressor bracket 100 is formed by stamping and bending a whole metal plate, greatly reducing the compressor parts and processing procedures, with a simpler structure, light weight, and easy to assemble.

[0035] Combined with Figure 5 , the compressor bracket 100 is provided with a first limiting arm 107 and a second limiting arm 108. When the compressor bracket 100 is installed inside the casing together with the core, the first limiting arm 107 and the second limiting arm 108 can cooperate with parts such as the casing of the compressor to limit the core in the horizontal direction, preventing the core of the compressor from shaking too much inside the casing and causing fatigue fracture of the metal inner exhaust pipe.

[0036] In some embodiments, referring to Figure 1 、 Figure 2 , the end of the first limiting arm 107 bends towards the second limiting arm 108, and the end of the second limiting arm 108 bends towards the first limiting arm 107. A U-shaped limiting space is formed between the first limiting arm 107 and the second limiting arm 108. With the help of the U-shaped limiting space, horizontal limiting of the core in multiple directions can be realized.

[0037] In some embodiments, referring to Figure 1 , the cylinder head component mounting portion 102 is provided with a third support arm 109 extending downward in the height direction. The compressor bracket 100 forms a single stator leg for connecting with the stator component of the compressor through the third support arm 109. The position of the single stator leg is between the crankshaft mounting portion 101 and the cylinder head component mounting portion 102, and is located at the neck position of the compressor bracket 100. With this structural form of the single stator leg, the compressor bracket 100 can more stably support the stator component, ensuring the stability of the compressor assembly.

[0038] The compressor bracket 100 is provided with a single stator leg, that is, the stator leg is only provided at one position. The technical solution of the present invention abandons the structural form in the prior art where the cylinder block is connected to the stator component through multiple stator legs, and adopts the design scheme of the compressor bracket 100 with a single stator leg. The structure is simpler, greatly reducing the compressor parts and processing procedures, significantly reducing the material consumption of the parts, and greatly reducing the cost of the compressor. The solution of the present invention is simple, easy to assemble, has reliable connection, and low cost.

[0039] Referring to Figure 3 , Figure 4 , Figure 5 , an embodiment of the present invention further provides a compressor, including a housing 300 and the compressor bracket 100 in some of the above embodiments. The housing 300 includes an upper housing 301 and a lower housing 302. The upper housing 301 is provided with a limiting boss 303 protruding into the interior of the housing 300. The limiting boss 303 is embedded between the first limiting arm 107 and the second limiting arm 108. The cooperation between the limiting boss 303 and the first limiting arm 107 and the second limiting arm 108 of the compressor frame plays a role in horizontal limiting, preventing the movement amplitude of the core of the compressor in the housing from being too large and causing fatigue fracture of the metal inner exhaust pipe.

[0040] Referring to Figure 5 , the limiting boss 303 is embedded in the U-shaped limiting space between the first limiting arm 107 and the second limiting arm 108. The side surface of the limiting boss 303 is provided with an arc-shaped limiting surface 304 corresponding to the first limiting arm 107 and the second limiting arm 108. The arc-shaped limiting surface 304 corresponds to the U-shaped contour of the limiting space, and can realize the horizontal limiting of the core in multiple directions.

[0041] Among them, the limiting boss 303 has a certain height. The present invention preferably selects the height of the limiting boss 303 to be 4.5 - 10.0 mm, and the limiting boss 303 is embedded into the limiting structure of the compressor bracket 100 to a certain depth. The present invention preferably selects the depth to be 1.5 - 6.5 mm.

[0042] A reasonable horizontal clearance is maintained between the inner contours of the first limiting arm 107 and the second limiting arm 108 and the surface of the limiting boss 303 of the upper shell 301, which can not only prevent abnormal collisions during normal operation, but also prevent the fatigue fracture of the inner exhaust pipe caused by severe bumps during transportation. The horizontal clearance of the present invention is preferably 2.0 - 6.0 mm, that is, the clearance between the arc-shaped limiting surface 304 and the compressor bracket 100 is 2.0 - 6.0 mm.

[0043] The compressor further includes a crankshaft 400. A bushing is provided in the shaft hole 103 of the compressor bracket 100, and the crankshaft 400 is installed in the bushing. The bushing can be made of powder metallurgy, cast iron or steel billet forging. The bushing is fixedly installed in the shaft hole 103 of the compressor bracket 100 by means of interference fit. The end of the bushing extends beyond the shaft hole 103 of the compressor bracket 100 to ensure that the crankshaft 400 is supported on the end of the bushing. An oil groove is provided at the end of the bushing for lubricating the end.

[0044] See Figure 7 , the inner contour of the limiting space should neither be too large nor too small. If the limiting space is too large, the material consumption is large and the cost is high; if the limiting space is too small, the crankshaft 400 cannot be assembled into the shaft hole 103. Therefore, the appropriate size of the limiting space is that the inner projection contour is slightly larger than the contour of the crankshaft 400 projected in the vertical direction, and a certain clearance can be maintained. For example, in some embodiments, the inner projection contour of the limiting space is 0.1 - 3.0 mm larger than the contour of the crankshaft 400 projected in the vertical direction to ensure that the crankshaft 400 can be assembled into the shaft hole 103 from top to bottom.

[0045] See Figure 1 , Figure 2 , Figure 7 , a crankshaft avoidance groove 110 is formed between the ends of the first limiting arm 107 and the second limiting arm 108. The crankshaft avoidance groove 110 has a certain width, and this width ensures that there is no interference during the vertical assembly of the crankshaft 400, that is, a certain clearance needs to be reserved.

[0046] See Figure 6 , Figure 7, the compressor further includes a cylinder liner 200 which can be made by powder metallurgy, cast iron or steel billet forging. The cylinder liner 200 is arranged in the positioning groove 106, and the positioning groove 106 is a profiling groove matching with the cylinder liner 200. A through cylinder bore is provided inside the cylinder liner 200. A limiting post 201 is provided at the tail of the cylinder bore of the cylinder liner 200, and a flat limiting surface 305 corresponding to the limiting post 201 is provided on the side surface of the limiting boss 303. The side surface of the limiting post 201 is matched with the flat limiting surface of the limiting boss 303 inside the upper shell 301, playing a role of horizontal limiting in the cylinder head direction. Thus, there are horizontal and vertical limiting functions between the movement and the upper shell 301 in the circumferential direction. There is a certain gap directly between the side surface of the limiting post 201 and the flat limiting surface 305 of the boss. Preferably, the gap in the present invention is 2.0 - 6.0 mm.

[0047] Further, referring to Figure 6 , Figure 7 , an outer flange 202 is provided at the front end of the cylinder liner 200, and the first support arm 104, the second support arm 105 and the third support arm 109 are provided with support positioning surfaces that abut against the outer flange 202 from the back side. Among them, the multiple support positioning surfaces provided by the first support arm 104, the second support arm 105 and the third support arm 109 are used for multi-point horizontal positioning of the cylinder liner 200, ensuring the positioning accuracy, and the positioning groove 106 formed between the first support arm 104 and the second support arm 105 further realizes the height-direction positioning of the cylinder liner 200.

[0048] Referring to Figure 1 , Figure 2 , the first support arm 104 and the second support arm 105 are symmetrically arranged on both sides of the cylinder liner 200. The first support arm 104 is provided with a first flange 111 bent outward, and the support positioning surface of the first support arm 104 is formed through the first flange 111. The second support arm 105 is provided with a second flange 112 bent outward, and the support positioning surface of the second support arm 105 is formed through the second flange 112. The third support arm 109 is bent once from the end of the cylinder head component installation part 102 towards the support block direction, and the support positioning surface of the third support arm 109 is formed. The support positioning surface of the first support arm 104, the support positioning surface of the second support arm 105 and the support positioning surface of the third support arm 109 are located in the same plane, and the three formed support positioning surfaces are used for multi-point horizontal positioning of the cylinder liner 200, ensuring the positioning accuracy.

[0049] Referring to Figure 7 , Figure 9, the compressor further includes a valve plate gasket, a suction valve plate, a valve plate, an exhaust valve plate, a cylinder head gasket, a cylinder head 500, and an elastic clip 600 disposed outside the end face of the cylinder liner 200. The elastic clip 600 is connected to the compressor bracket 100 and presses each cylinder head component against the outside of the end face of the cylinder liner 200. The first flange 111 and the second flange 112 protrude from the outer peripheral surface of the outer flange 202. The third support arm 109 is bent twice to form a third flange 113 protruding from the outer peripheral surface of the outer flange 202. The elastic clip 600 is provided with connecting arms 601 corresponding to the first flange 111, the second flange 112, and the third flange 113. The connecting arms 601 of the elastic clip 600 are connected to the first flange 111, the second flange 112, and the third flange 113 through a first fastener 602, and press the suction valve plate, the valve plate, the exhaust valve plate, and the cylinder head 500 against the end face of the cylinder liner 200. Among them, the first fastener 602 can be a screw or a rivet, etc. For example, in some embodiments, after the three connecting arms 601 of the elastic clip 600 are assembled with the three flanges of the compressor bracket 100 through rivets, there is a certain gap. Therefore, the elastic clip 600 has an appropriate pre-tightening force, so that the cylinder head components will not be pushed open by the exhaust pressure during the operation of the piston, resulting in internal leakage.

[0050] See Figure 9 , the compressor further includes a stator component 700. The stator component 700 includes an iron core 701. The middle of the iron core 701 is provided with an inner hole of the iron core. The compressor bracket 100 is disposed at one end of the iron core 701. The cylinder head component mounting portion 102 is offset to one side of the axis of the iron core 701. The iron core 701 is provided with a support block on the side where the cylinder head component mounting portion 102 is offset. The single stator leg of the compressor bracket 100 is connected to the support block 702. The compressor bracket 100 is provided with a single stator leg, that is, the stator leg is only provided at one position. Corresponding to the offset structural form of the compressor bracket 100, a support block 702 is provided on the side where the cylinder head component mounting portion 102 of the iron core 701 is offset. Further, the connection between the compressor bracket 100 and the stator component 700 is realized through the cooperation connection between the single stator leg and the support block 702. The technical solution of the present invention abandons the structural form in the prior art in which the cylinder block is connected to the stator component 700 through multiple stator legs, and adopts the design scheme of the compressor bracket 100 with a single stator leg, which has a simpler structure, greatly reduces the compressor parts and processing procedures, greatly reduces the material consumption of the parts, and greatly reduces the cost of the compressor. The solution of the present invention is simple, easy to assemble, has reliable connection, and low cost.

[0051] In the prior art, stator screw mounting holes are usually provided on the stator punching sheet, so the length and width dimensions of the stator punching sheet become larger, greatly increasing the quota of the stator punching sheet and increasing the material cost. In some embodiments of the present invention, see Figure 8, the iron core 701 is formed by stacking silicon steel sheets with a circular profile. The iron core 701 is cylindrical. Structures such as stator screw mounting holes are no longer provided on the silicon steel sheets of the iron core 701, and the shape is a regular circle, making the length and width dimensions of the stator punching sheet smaller, greatly reducing the quota of the stator punching sheet, and reducing the material cost.

[0052] Among them, referring to Figure 8 , the iron core 701 is formed by spiral winding and stacking long strip-shaped toothed silicon steel sheets. The support block 702 is provided with an arc-shaped fitting surface. The arc-shaped fitting surface of the support block 702 fits on the outer cylindrical surface of the iron core 701 and is fixedly connected to the outer cylindrical surface of the iron core 701. In order to reduce the number of welds and minimize the negative impact of welding on the performance of the motor, a weld for welding the support block 702 to the iron core 701 is provided along the side of the support block 702. The silicon steel sheets of each layer of the iron core 701 are fastened together by one weld. After the support block 702 is attached to the iron core 701, it is welded together with the iron core 701. The iron core 701 originally needs to be welded and connected. Now, after attaching the support block 702, it is welded simultaneously, saving one welding operation.

[0053] Referring to Figure 9 , the stator component 700 further includes a first skeleton 703 and a second skeleton 704 provided at both ends of the iron core 701. At least one of the first skeleton 703 and the second skeleton is provided with a spring support 705, and the spring support is supported on the housing 300 through a spring 706.

[0054] The embodiment of the present invention also provides a refrigeration device, including the compressor in any of the above embodiments. The refrigeration device includes but is not limited to air conditioners, refrigerators, etc.
