Description

Technical Field

[0001] This utility model relates to the technical field of oil guide plate installation, and in particular to an automatic pressing device for compressor oil guide plates and the compressor assembly system formed therefrom. Background Technology

[0002] The oil guide vanes in the compressor pump assembly need to be manually inserted into the crankshaft of the pump assembly by an operator, and then manually pressed in using a press-in tool. Existing press-in tools include... Figure 1 , Figure 2 As shown, after manually placing the oil guide plate 11 into the inner hole of the crankshaft 25, manually drive it as follows: Figure 1 and Figure 2 The press-in fixture shown presses down, pressing the oil guide plate 11 into the inner hole of the crankshaft 25 through the protruding structure at the bottom of the press-in fixture. The height of the protrusion at the head of the press-in fixture is used to control the pressing depth of the oil guide plate 11. The top of the oil guide plate 11 is provided with a snap-fit ​​part, the size of which is slightly larger than the inner diameter of the crankshaft. This ensures that when the oil guide plate 11 is pressed into the inner diameter of the crankshaft 25, the snap-fit ​​part and the inner diameter of the crankshaft 25 are interference-fitted, ensuring that the oil guide plate 11 does not move up and down in the inner hole of the crankshaft 25 after being positioned.

[0003] In existing technologies, if the pressing driving force deviates from the crankshaft's centerline during the pressing assembly of the oil guide plate, it cannot ensure that the oil guide plate is aligned with the crankshaft. This results in the oil guide plate being misaligned relative to the crankshaft, affecting its normal operation. This is especially true for plate-shaped oil guide plates, which are more prone to center misalignment during pressing assembly. Therefore, ensuring that the oil guide plate remains coaxially aligned with the crankshaft throughout the assembly process is a core requirement in the design of automatic pressing devices. Summary of the Invention

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide an automatic pressing device for compressor oil guide plates. The lifting drive component can drive the pressing component to adjust its position in three dimensions, thereby achieving precise positioning of the pressing component relative to the crankshaft. This ensures that the pressing component coincides with the axis of the crankshaft before pressing down the oil guide plate. In other words, by adjusting the sliding connection structure in the component, the coaxial alignment of the pressing component and the crankshaft can be achieved, ensuring that the installation position of the oil guide plate is accurate and effective, and improving the automatic pressing efficiency of the oil guide plate.

[0005] An automatic pressing device for compressor oil guide plates includes an adjusting component and a pressing component; The adjustment assembly includes a lifting drive, a first adjustment component, and a second adjustment component. The first adjustment component includes a first slide rail arranged along a first direction, and the second adjustment component includes a second slide rail arranged along a second direction. The pressing component for abutting against the oil guide plate is fixedly connected to the second slide rail, and the second slide rail is slidably connected to the first slide rail. The lifting drive is slidably connected to the first slide rail. The first direction and the second direction are perpendicular to each other and both are perpendicular to the driving direction of the lifting drive.

[0006] In this application, the driving direction of the lifting drive component, the extension direction of the first slide rail, and the extension direction of the second slide rail are perpendicular to each other. At the same time, the pressing component and the second slide rail are fixedly connected. The second slide rail can slide relative to the first slide rail, and the lifting drive component can slide relative to the first slide rail. In this way, the lifting drive component can drive the pressing component to adjust its position in three dimensions, so as to achieve precise positioning of the pressing component relative to the crankshaft and ensure that the pressing component coincides with the axis of the crankshaft before pressing down the oil guide plate.

[0007] In a preferred embodiment of this invention, the first adjusting member further includes a first slider, the second adjusting member further includes a second slider, the lifting drive member is fixedly connected to the first slider, the first slider is slidably connected to the first slide rail, the first slide rail is fixedly connected to the second slider, and the second slider is slidably connected to the second slide rail.

[0008] To ensure stable sliding between the lifting drive component and the first slide rail, this application provides a fixed connection between the lifting drive component and the first slide rail, with the first slide rail slidably disposed inside it. A first slider enables a sliding connection between the first slide rail and the lifting drive component, which have completely different structures and positions. Similarly, to ensure relative movement between the first and second slide rails, this application provides a slidable second slider inside the second slide rail, and fixes the second slider to the first slide rail. The second slider enables a sliding connection between the first and second slide rails. Preferably, the lifting drive component is located above the first slide rail, and the first slide rail is located above the second slide rail. The first and second sliders enable vertical sliding between the lifting drive component, the first slide rail, and the second slide rail, improving the efficiency of the adjustment component's three-dimensional position adjustment.

[0009] In a preferred embodiment of this invention, the adjustment assembly further includes a connecting plate, and the first slider is fixedly connected to the lifting drive component via the connecting plate.

[0010] In this application, the lifting drive component can be a cylinder or a motor or other drive components. In order to facilitate the stable installation of the lifting drive component, a connecting plate is provided at the bottom of the lifting drive component, and the connecting plate and the first slide rail are fixed together. With the help of the connecting plate, the first slider can be set as a small sliding component located only in the first slider. At the same time, the connecting plate can also serve as a load-bearing support plate for the lifting drive component.

[0011] In a preferred embodiment of this invention, the adjustment assembly further includes a floating plate, and the second slide rail is fixedly connected to the first slide rail via the floating plate.

[0012] In this application, the floating plate can serve as a support plate for the first slide rail, providing support for its installation. Preferably, the cross-sectional area of ​​the floating plate needs to be larger than that of the first slide rail to ensure that the first slide rail is completely located on the upper surface of the floating plate, and the first slider and the lifting drive can slide relative to the floating plate along a first direction. The top of the floating plate is fixedly connected to the first slide rail, and the bottom of the floating plate is fixedly connected to the second slider. The first slide rail can slide relative to the first slide rail, and the second slide rail can slide relative to the second slide rail. This application achieves a stable and slidable connection between the first and second slide rails in the vertical direction through the floating plate.

[0013] In a preferred embodiment of this invention, the first slide rail and the first slider are provided with a first fixing through hole, and the second slide rail and the second slider are provided with a second fixing through hole.

[0014] When the adjusting assembly needs to move the pressing assembly for position adjustment, no fasteners are installed in the first and second fixed through holes. At this time, the adjusting assembly can move the pressing assembly in three dimensions to ensure the centerline of the pressing assembly and the crankshaft is aligned. When the adjusting assembly moves the pressing assembly into position, i.e., when the centerline of the pressing assembly and the crankshaft is aligned, the fasteners are inserted into the first and second fixed through holes. This ensures that the components in the adjusting assembly no longer move relative to each other, and that the force applied to the oil guide plate is fixed in direction during the pressing operation, preventing the oil guide plate from tilting or shifting during pressing.

[0015] In a preferred embodiment of this invention, the pressing assembly includes a pressing drive and a pressing fixture. The pressing fixture has a hollow channel, and a pressing head is disposed within the hollow channel. The pressing drive and the pressing head are fixedly connected. The pressing head is used to abut against the oil guide plate, and the pressing drive is fixedly connected to the second slide rail.

[0016] The top of the pressure head, i.e., the side connected to the pressing drive, has an outer diameter that is approximately equal to the inner diameter of the hollow channel, ensuring that the pressing drive can smoothly move the pressure head within the hollow channel. The bottom of the pressure head, i.e., the side away from the pressing drive, has a protrusion facing the crankshaft. The inner diameter of this protrusion is smaller than the inner diameter of the hollow channel and also smaller than the inner diameter of the crankshaft; simultaneously, the axis of the protrusion coincides with the axis of the pressure head. When the pressure head pushes down the oil guide plate, the protrusion can penetrate deep into the crankshaft. The height of the protrusion is used to position the top of the oil guide plate, ensuring that the distance between the top of the oil guide plate and the top of the crankshaft is equal to the height of the protrusion. This application, through the structural design of the pressure head, achieves precise positioning of the oil guide plate's insertion position, while also ensuring that the oil guide plate slides stably along the extension direction of the hollow channel under the action of the pressing drive and the pressure head.

[0017] In a preferred embodiment of this invention, a protective sleeve is nested at the end of the hollow channel away from the pressing drive component.

[0018] In this application, the outer diameter of the top of the pressure head is slightly larger than the inner diameter of the crankshaft, the outer diameter of the protruding structure at the bottom of the pressure head is smaller than the inner diameter of the crankshaft, and the inner diameter of the hollow channel is larger than the inner diameter of the crankshaft. When the lifting drive component drives the pressing assembly to descend to the position where it abuts against the crankshaft, the bottom of the pressing tool, i.e. the outer side of the bottom of the hollow channel, abuts against the crankshaft first. The protective sleeve can protect and buffer the crankshaft, avoiding rigid collision between the pressing tool and the crankshaft.

[0019] In a preferred embodiment of this invention, the outer diameter of the top end of the oil guide plate is interference-fitted with the inner diameter of the crankshaft; the outer diameter of the pressure head is smaller than the outer diameter of the top end of the oil guide plate.

[0020] In this application, the outer diameter of the top of the oil guide plate is interference-fitted with the inner diameter of the crankshaft. Simultaneously, the difference in size between the outer diameter of the top of the oil guide plate and the inner diameter of the crankshaft is small. This ensures that under external force, the top of the oil guide plate can still move relative to the crankshaft even in the interference-fit state. Without external force, the top of the oil guide plate is firmly connected to the crankshaft, preventing relative movement. By setting the outer diameter of the top of the oil guide plate, a tight connection between the oil guide plate and the crankshaft is ensured.

[0021] In a preferred embodiment of this invention, the pressing assembly further includes a clamping drive and a gripper. The centerlines of the pressing drive and the clamping drive coincide. The gripper is circumferentially distributed along the circumferential edge of the clamping drive. The clamping drive is used to drive the gripper to clamp or release the pump body assembly. The crankshaft is located at the center of the pump body assembly.

[0022] In this application, the clamping drive component can drive the grippers to clamp or release the pump body assembly. After the clamping drive component drives the grippers to clamp the pump body assembly, the centerlines of the clamping drive component and the pump body assembly coincide. Since the centerlines of the crankshaft and the pump body assembly coincide, the centerlines of the clamping drive component and the pressing drive component coincide, and the centerline of the pressing drive component and the pressure head coincide, thus ensuring that the centerlines of the pressure head and the crankshaft coincide. In other words, the process of the clamping drive component driving the grippers to clamp the pump body assembly in this application is the process of aligning the pressure head and the crankshaft. Through the clamping drive component and the grippers, rapid alignment adjustment of the pressure head and the crankshaft can be achieved, further improving the pressing efficiency and pressing accuracy of the oil guide plate.

[0023] The second objective of this application is to provide a compressor assembly system, including an automatic pressing device for compressor oil guide plates as described above.

[0024] The beneficial effects of this utility model are as follows: This utility model provides an automatic pressing device for a compressor oil guide plate, comprising an adjustment component and a pressing component; the adjustment component includes a lifting drive component, a first adjustment component, and a second adjustment component, the first adjustment component including a first slide rail arranged along a first direction, the second adjustment component including a second slide rail arranged along a second direction, the pressing component for abutting against the oil guide plate being fixedly connected to the second slide rail, the second slide rail being slidably connected to the first slide rail, and the lifting drive component being slidably connected to the first slide rail; the first direction and the second direction are perpendicular to each other and both are perpendicular to the driving direction of the lifting drive component. In this application, the driving direction of the lifting drive component, the extension direction of the first slide rail, and the extension direction of the second slide rail are all perpendicular to each other. At the same time, the pressing component and the second slide rail are fixedly connected. The second slide rail can slide relative to the first slide rail, and the lifting drive component can slide relative to the first slide rail. In this way, the lifting drive component can drive the pressing component to adjust its position in three dimensions, thereby achieving precise positioning of the pressing component relative to the crankshaft. This ensures that the pressing component coincides with the axis of the crankshaft before pressing down the oil guide plate. That is, by adjusting the sliding connection structure in the component, the coaxial alignment of the pressing component and the crankshaft can be achieved, ensuring that the installation position of the oil guide plate is accurate and effective, and improving the automatic pressing efficiency of the oil guide plate.

[0025] This application also provides a compressor assembly system, including an automatic pressing device for compressor oil guide plates as described above, which can realize efficient and precise automatic pressing of oil guide plates and crankshaft in compressor, significantly improving the assembly efficiency of oil guide plates and crankshaft, improving the assembly accuracy and assembly speed of compressor, and ensuring the performance stability of compressor.

[0028] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0029] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0030] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Example 1 like Figures 3-7 As shown, this application provides an automatic pressing device for a compressor oil guide plate, including an adjustment component and a pressing component; the adjustment component includes a lifting drive 30, a first adjustment component, and a second adjustment component. The first adjustment component includes a first slide rail 16 arranged along a first direction, and the second adjustment component includes a second slide rail 19 arranged along a second direction. The pressing component, which abuts against the oil guide plate 11, is fixedly connected to the second slide rail 19, and the second slide rail 19 is slidably connected to the first slide rail 16. The lifting drive 30 is slidably connected to the first slide rail 16. The first direction and the second direction are perpendicular to each other and both are perpendicular to the driving direction of the lifting drive 30.

[0032] In this application, the driving direction of the lifting drive 30 can be, for example, vertical. The first direction and the second direction are two mutually perpendicular directions in the horizontal plane. The lifting drive 30 can drive the first adjusting member, the second adjusting member, and the pressing assembly to move vertically as a whole. The first slide rail 16 is slidably connected to the lifting drive 30, meaning the first slide rail 16 can drive the second slide rail 19 and the pressing assembly to move horizontally in the first direction. The second slide rail 19 is slidably connected to the first slide rail 16, meaning the second slide rail 19 can drive the pressing assembly to move horizontally in the second direction, thereby achieving position adjustment of the pressing assembly in three-dimensional space and ensuring that before the oil guide plate 11 is pressed in, the center line or axis of the pressing assembly, the oil guide plate 11, and the crankshaft 25 coincide.

[0033] It should be noted that the sliding of the first slide rail 16 and the second slide rail 19 in this application occurs during the position adjustment stage before the pressing action. Once the center line or axis of the pressing assembly, the oil guide plate 11 and the crankshaft 25 are aligned, the positions of the first slide rail 16 and the second slide rail 19 are fixed by fasteners to ensure that the positions of the first slide rail 16 and the second slide rail 19 remain fixed during the pressing operation, thus preventing the direction of the force applied to the oil guide plate 11 from shifting during the pressing operation.

[0034] In this application, the driving direction of the lifting drive 30, the extension direction of the first slide rail 16, and the extension direction of the second slide rail 19 are perpendicular to each other. At the same time, the pressing component and the second slide rail 19 are fixedly connected. The second slide rail 19 can slide relative to the first slide rail 16, and the lifting drive 30 can slide relative to the first slide rail 16. In this way, the lifting drive 30 can drive the pressing component to adjust its position in three dimensions, so as to achieve precise positioning of the pressing component relative to the crankshaft 25. This ensures that the pressing component coincides with the axis of the crankshaft 25 before pressing down the oil guide plate 11. That is, by adjusting the sliding connection structure in the component, the coaxial alignment of the pressing component and the crankshaft 25 can be achieved, ensuring that the installation position of the oil guide plate 11 is accurate and effective, and improving the automatic pressing efficiency of the oil guide plate.

[0035] In this application, the pressing assembly is preferably designed as an automatic pressing assembly including a pressing drive 24. When the adjusting assembly moves the pressing assembly to the center position with the crankshaft 25 in the compressor, the pressing drive 24 drives the pressing fixture 14 to press the oil guide plate 11, ensuring that the pressing drive 24 in the pressing assembly coincides with the axis of the oil guide plate 11 and the crankshaft 25.

[0036] In this application, the oil guide sheet 11 can specifically be a sheet-like structure, such as... Figure 4 As shown, the top outer diameter of the oil guide plate 11 is slightly larger than the inner diameter of the crankshaft 25 to achieve an interference fit between the top of the oil guide plate 11 and the crankshaft 25. When the press-fit assembly presses the oil guide plate 11 into the crankshaft 25, the top of the oil guide plate 11 is tightly fitted with the inner diameter of the crankshaft 25 to prevent the position of the oil guide plate 11 from shifting during compressor operation. The bottom outer diameter of the oil guide plate 11 is smaller than the inner diameter of the crankshaft 25. Here, "bottom" refers to the area other than the top where a tight fit is required; all areas must be smaller than the inner diameter of the crankshaft 25 to ensure that the oil guide plate 11 can smoothly enter the crankshaft 25 under the action of the press-fit assembly.

[0037] Example 2 like Figures 3-7 As shown, this application provides an automatic pressing device for a compressor oil guide plate, including an adjustment component and a pressing component; the adjustment component includes a lifting drive 30, a first adjustment component, and a second adjustment component. The first adjustment component includes a first slide rail 16 arranged along a first direction, and the second adjustment component includes a second slide rail 19 arranged along a second direction. The pressing component, which abuts against the oil guide plate 11, is fixedly connected to the second slide rail 19, and the second slide rail 19 is slidably connected to the first slide rail 16. The lifting drive 30 is slidably connected to the first slide rail 16. The first direction and the second direction are perpendicular to each other and both are perpendicular to the driving direction of the lifting drive 30.

[0038] Furthermore, the first adjusting member further includes a first slider 17, the second adjusting member further includes a second slider 20, the lifting drive member 30 is fixedly connected to the first slider 17, the first slider 17 is slidably connected to the first slide rail 16, the first slide rail 16 is fixedly connected to the second slider 20, and the second slider 20 is slidably connected to the second slide rail 19.

[0039] To ensure stable sliding between the lifting drive component 30 and the first slide rail 16, this application provides a fixed connection between the lifting drive component 30 and the first slide rail 16. The first slide rail 16 is slidably disposed inside the lifting drive component 30. With the aid of the first slider 17, a sliding connection can be achieved between the first slide rail 16 and the lifting drive component 30, which have completely different structures and positions. Similarly, to ensure relative movement between the first slide rail 16 and the second slide rail 19, this application provides a slidable second slider 20 within the second slide rail 19 and fixes the second slider 20 to the first slide rail 16. With the aid of the second slider 20, a sliding connection can be achieved between the first slide rail 16 and the second slide rail 19. Preferably, the lifting drive component 30 is located above the first slide rail 16, and the first slide rail 16 is located above the second slide rail 19. With the aid of the first slider 17 and the second slider 20, vertical sliding between the lifting drive component 30, the first slide rail 16, and the second slide rail 19 can be achieved, improving the efficiency of the adjustment component's position adjustment in the three-dimensional direction.

[0040] Furthermore, the adjustment assembly also includes a connecting plate 15, and the first slider 17 is fixedly connected to the lifting drive component 30 through the connecting plate 15.

[0041] In this application, the lifting drive component 30 can be a drive component such as a cylinder or a motor. In order to facilitate the stable installation of the lifting drive component 30, a connecting plate 15 is provided at the bottom of the lifting drive component 30, and the connecting plate 15 and the first slide rail 16 are fixed together. With the help of the connecting plate 15, the first slider 17 can be set as a small sliding component located only in the first slider 17. At the same time, the connecting plate 15 can also serve as a load-bearing support plate for the lifting drive component 30.

[0042] Furthermore, the adjustment assembly also includes a floating plate 18, and the second slide rail 19 is fixedly connected to the first slide rail 16 via the floating plate 18.

[0043] In this application, the floating plate 18 can serve as a support plate for the first slide rail 16, providing support for the installation of the first slide rail 16. Preferably, the cross-sectional area of ​​the floating plate 18 needs to be larger than the cross-sectional area of ​​the first slide rail 16 to ensure that the first slide rail 16 is completely located on the upper surface of the floating plate 18, and the first slider 17 and the lifting drive 30 can slide relative to the floating plate 18 along a first direction. The top of the floating plate 18 is fixedly connected to the first slide rail 16, and the bottom of the floating plate 18 is fixedly connected to the second slider 20. The first slide rail 16 can slide relative to the first slide rail 16, and the second slide rail 19 can slide relative to the second slide rail 19. This application achieves a stable and slidable connection between the first slide rail 16 and the second slide rail 19 in the vertical direction through the floating plate 18.

[0044] Furthermore, the first slide rail 16 and the first slider 17 are provided with a first fixing through hole, and the second slide rail 19 and the second slider 20 are provided with a second fixing through hole.

[0045] When the adjusting assembly needs to move the pressing assembly for position adjustment, no fasteners are installed in the first and second fixed through holes. At this time, the adjusting assembly can move the pressing assembly in three dimensions to ensure that the centerline of the pressing assembly and the crankshaft 25 are aligned. When the adjusting assembly moves the pressing assembly into place, that is, when the centerline of the pressing assembly and the crankshaft 25 are aligned, the fasteners are inserted into the first and second fixed through holes to ensure that the components in the adjusting assembly no longer move relative to each other. This ensures that the direction of the force applied to the oil guide plate 11 is fixed during the pressing operation, and prevents the position of the oil guide plate 11 from tilting or shifting during the pressing process.

[0046] Example 3 like Figures 3-7 As shown, this application provides an automatic pressing device for a compressor oil guide plate, including an adjustment component and a pressing component; the adjustment component includes a lifting drive 30, a first adjustment component, and a second adjustment component. The first adjustment component includes a first slide rail 16 arranged along a first direction, and the second adjustment component includes a second slide rail 19 arranged along a second direction. The pressing component, which abuts against the oil guide plate 11, is fixedly connected to the second slide rail 19, and the second slide rail 19 is slidably connected to the first slide rail 16. The lifting drive 30 is slidably connected to the first slide rail 16. The first direction and the second direction are perpendicular to each other and both are perpendicular to the driving direction of the lifting drive 30.

[0047] Furthermore, the pressing assembly includes a pressing drive 24 and a pressing fixture 14. The pressing fixture 14 is provided with a hollow channel, and a pressing head 12 is provided in the hollow channel. The pressing drive 24 and the pressing head 12 are fixedly connected.

[0048] like Figure 5 As shown, the outer diameter of the top of the pressure head 12, i.e., the side connected to the pressure drive 24, is approximately equal to the inner diameter of the hollow channel, ensuring that the pressure drive 24 can drive the pressure head 12 to move smoothly within the hollow channel. The bottom of the pressure head 12, i.e., the side away from the pressure drive 24, has a protrusion facing the crankshaft 25. The inner diameter of this protrusion is smaller than the inner diameter of the hollow channel and also smaller than the inner diameter of the crankshaft 25. Simultaneously, the axis of the protrusion coincides with the axis of the pressure head 12. When the pressure head 12 drives the oil guide plate 11 downwards, the protrusion can penetrate deep into the crankshaft 25. The height of the protrusion is used to position the top of the oil guide plate 11, ensuring that the distance between the top of the oil guide plate 11 and the top of the crankshaft 25 is equal to the height of the protrusion. Through the structural design of the pressure head 12, this application can achieve precise positioning of the oil guide plate 11 in the pressing position, and at the same time ensure that the oil guide plate 11 slides stably along the extension direction of the hollow channel under the drive of the pressing drive 24 and the pressure head 12.

[0049] Furthermore, a protective sleeve 13 is nested at the end of the hollow channel away from the press-in drive member 24.

[0050] In this application, the outer diameter of the top of the pressure head 12 is slightly larger than the inner diameter of the crankshaft 25, the outer diameter of the protruding structure at the bottom of the pressure head 12 is smaller than the inner diameter of the crankshaft 25, and the inner diameter of the hollow channel is larger than the inner diameter of the crankshaft 25. When the lifting drive component 30 drives the pressing assembly to descend to the position where it abuts against the crankshaft 25, the bottom of the pressing fixture 14, i.e. the outer side of the bottom of the hollow channel, abuts against the crankshaft 25 first. The protective sleeve 13 can protect and buffer the crankshaft 25, avoiding rigid collision between the pressing fixture 14 and the crankshaft 25.

[0051] Furthermore, the outer diameter of the top end of the oil guide plate 11 is interference-fitted with the inner diameter of the crankshaft 25; the outer diameter of the pressure head 12 is smaller than the outer diameter of the top end of the oil guide plate 11.

[0052] In this application, the outer diameter of the top end of the oil guide plate 11 is interference-fitted with the inner diameter of the crankshaft 25. Simultaneously, the difference in size between the outer diameter of the top end of the oil guide plate 11 and the inner diameter of the crankshaft 25 is small. This ensures that under external force, the top end of the oil guide plate 11 can still move relative to the crankshaft 25 even in the interference-fit state. Without external force, the top end of the oil guide plate 11 is firmly connected to the crankshaft 25, preventing relative movement. By setting the outer diameter of the top end of the oil guide plate 11, a firm connection between the oil guide plate 11 and the crankshaft 25 is ensured.

[0053] Furthermore, the pressing assembly also includes a clamping drive 22 and a gripper 23. The axis of the pressing drive 24 and the clamping drive 22 coincides. The gripper 23 is circumferentially distributed on the circumferential edge of the clamping drive 22. The clamping drive 22 is used to drive the gripper 23 to clamp or release the pump body assembly 27. The crankshaft 25 is located at the center of the pump body assembly 27.

[0054] In this application, the clamping drive 22 can drive the gripper 23 to clamp or release the pump body assembly 27. After the clamping drive 22 drives the gripper 23 to clamp the pump body assembly 27, the axis of the clamping drive 22 and the pump body assembly 27 coincides. Since the axis of the crankshaft 25 and the pump body assembly 27 coincides, the axis of the clamping drive 22 and the pressing drive 24 coincide, and the axis of the pressing drive 24 and the pressing head 12 coincide, thus ensuring that the axis of the pressing head 12 and the crankshaft 25 coincide. In other words, the process of the clamping drive 22 driving the gripper 23 to clamp the pump body assembly 27 in this application is the alignment process of the pressing head 12 and the crankshaft 25. Through the clamping drive 22 and the gripper 23, rapid alignment adjustment of the pressing head 12 and the crankshaft 25 can be achieved, further improving the pressing efficiency and pressing accuracy of the oil guide plate 11.

[0055] Example 4 like Figures 3-7 As shown, this application provides an automatic pressing device for compressor oil guide plates, including an adjusting component and a pressing component. The adjusting component is used to drive the pressing component and crankshaft 25 for alignment. The pressing component is used to automatically press the oil guide plate. The outer diameter of the top end of the oil guide plate 11 is interference-fitted with the inner diameter of the crankshaft 25. The crankshaft 25 is located at the center of the pump body assembly 27, which is fixed inside the air conditioner via a flange 26. In this application, the adjusting component is disposed in a frame 28, which is located on the side of a production line 29 for transporting compressors containing the pump body assembly 27. Two parallel automatic pressing devices can be disposed in the frame 28 to improve the pressing efficiency of the oil guide plate.

[0056] Specifically, such as Figure 3 and Figure 6As shown, the adjustment assembly includes a lifting drive 30, a connecting plate 15, a floating plate 18, a first adjustment component, and a second adjustment component. The first adjustment component includes a first slide rail 16 arranged along a first direction and a first slider 17 slidable inside the first slide rail 16. The second adjustment component includes a second slide rail 19 arranged along a second direction and a second slider 20 slidable inside the second slide rail 19. The bottom of the lifting drive 30 is fixedly connected to the upper surface of the connecting plate 15, the lower surface of the connecting plate 15 is fixedly connected to the top of the first slider 17, the first slider 17 is slidably located inside the first slide rail 16, the lower surface of the first slide rail 16 is fixedly connected to the upper surface of the floating plate 18, the lower surface of the floating plate 18 is fixedly connected to the second slider 20, the second slider 20 is slidably located inside the second slide rail 19, the lower surface of the second slide rail 19 is fixedly connected to the clamping mounting plate 21, and the clamping drive 22 is fixed to the lower surface of the clamping mounting plate 21.

[0057] The first slide rail 16 and the first slider 17 are provided with a first fixing through hole, and the second slide rail 19 and the second slider 20 are provided with a second fixing through hole. A fastener inserted into the first fixing through hole can fix the position of the first slide rail 16 and the first slider 17, and a fastener inserted into the second fixing through hole can fix the position of the second slide rail 19 and the second slider 20. In this application, the fastener can specifically be a fastening screw, etc.

[0058] like Figure 3 and Figure 7 As shown, the press-in assembly includes a clamping drive 22, grippers 23, a press-in drive 24, a press-in fixture 14, and a pressing-in drive 24. The centerlines of the press-in drive 24 and the clamping drive 22 coincide. The grippers 23 are circumferentially distributed along the circumferential edge of the clamping drive 22. The clamping drive 22 is used to drive the grippers 23 to clamp or release the pump body assembly 27. The number of grippers 23 is as follows: Figure 7 As shown, it can be set to three, with the three grippers 23 evenly distributed circumferentially along the axis of the gripping drive member 22.

[0059] The pressing fixture 14 is provided with a hollow channel, and a pressing head 12 is disposed within the hollow channel. The pressing drive 24 and the pressing head 12 are fixedly connected. A protective sleeve 13 is nested at the end of the hollow channel away from the pressing drive 24. The outer diameter of the top of the pressing head 12, i.e., the side connected to the pressing drive 24, is approximately equal to the inner diameter of the hollow channel, ensuring that the pressing drive 24 can drive the pressing head 12 to move smoothly within the hollow channel. The bottom of the pressing head 12, i.e., the side away from the pressing drive 24, is provided with a protrusion facing the crankshaft 25. The inner diameter of this protrusion is smaller than the inner diameter of the hollow channel and smaller than the inner diameter of the crankshaft 25. At the same time, the centerline of the protrusion coincides with the centerline of the pressing head 12.

[0060] When the compressor containing the pump assembly 27 in production line 29 is transferred to the side of the frame 28, the lifting drive 30 drives the first adjusting member, the second adjusting member, and the pressing component to move downwards. Simultaneously, the pressing component is guided by a hand or robotic arm to move above the pump assembly 27. During this process, the lifting drive 30, the connecting plate 15, and the first slider 17 are fixed together and can move relative to the first slide rail 16. The first slide rail 16, the floating plate 18, and the second slider 20 are fixed together and can move relative to the second slide rail 19. The second slide rail 19, the clamping mounting plate 21, the clamping drive 22, and the pressing drive 24 are fixed together, with the pressing drive 24 located at the center of the clamping drive 22, and their axes coinciding. This structure ensures that the clamping drive 22 and the pressing drive 24 move up and down under the drive of the lifting drive 30 and move horizontally via the first slide rail 16 and the second slide rail 19, achieving alignment with the pump assembly 27.

[0061] When the adjusting assembly needs to move the pressing assembly for position adjustment, no fasteners are installed in the first and second fixed through holes. At this time, the adjusting assembly can move the pressing assembly in three dimensions to ensure that the centerline of the pressing assembly and the crankshaft 25 are aligned. When the adjusting assembly moves the pressing assembly into position, that is, when the centerline of the pressing assembly and the crankshaft 25 are aligned, the fasteners are inserted into the first and second fixed through holes to ensure that the components in the adjusting assembly no longer move relative to each other.

[0062] When the lifting drive 30 drives the pressing assembly to descend to the position where it abuts against the crankshaft 25, the bottom of the pressing fixture 14, i.e. the outer bottom of the hollow channel, abuts against the crankshaft 25 first. The protective sleeve 13 can protect and buffer the crankshaft 25, avoiding rigid collision between the pressing fixture 14 and the crankshaft 25.

[0063] When the pressing component moves above the pump body assembly 27, the clamping drive 22 drives the gripper 23 to clamp the pump body assembly 27. The axis of the clamping drive 22 and the pump body assembly 27 coincides. Since the axis of the crankshaft 25 and the pump body assembly 27 coincides, the axis of the clamping drive 22 and the pressing drive 24 coincides, and the axis of the pressing drive 24 and the pressing head 12 coincides, thus ensuring that the axis of the pressing head 12 and the crankshaft 25 coincide.

[0064] The press-in drive 24 drives the press head 12 to press down until it comes into contact with the oil guide plate 11. When the press head 12 drives the oil guide plate 11 to press down, the protruding structure can penetrate into the crankshaft 25. The height of the protruding structure is used to position the top of the oil guide plate 11 to ensure that the distance between the top of the oil guide plate 11 and the top of the crankshaft 25 is equal to the height of the protruding structure.

[0065] This application utilizes an adjustment assembly, a clamping drive 22, and grippers 23 to achieve forced alignment of the crankshaft 25 and the oil guide plate 11. The forced alignment in this application is achieved as follows: When switching compressor models, manual adjustment of the front, back, left, and right sides is slow and difficult to achieve. In this application, when adjusting the alignment by switching compressor models, the fasteners in the first and second fixed through holes are removed. Then, the clamping drive 22 is controlled to clamp the pump body. During clamping, the simultaneous movement of the clamping drive 22 ensures forced alignment. Finally, the fasteners are inserted into the first and second fixed through holes to complete the alignment adjustment.

[0066] This application also provides a compressor assembly system, including an automatic pressing device for compressor oil guide plates as described above, which can realize efficient and precise automatic pressing of oil guide plates and crankshaft in compressor, significantly improving the assembly efficiency of oil guide plates and crankshaft, improving the assembly accuracy and assembly speed of compressor, and ensuring the performance stability of compressor.
