Description

Technical Field

[0001] This application belongs to the field of assembly technology, and in particular relates to a device and method for controlling the assembly accuracy of irregularly shaped eccentric products. Background Technology

[0002] The irregularly shaped eccentric product includes a shell and a cone. The shell is open at both ends and hollow inside, and one end of the cone has a conical head. Based on market demand, the shell is formed by fitting an irregular curve. The cone is installed inside the shell. It is required that the center of the assembled cone should be the assembly center of the irregularly shaped eccentric product. A coordinate system is established based on one end face of the shell. The shell and the cone need to be aligned in each quadrant region.

[0003] However, when the shell has a multi-center structure, the center of the shell is usually not the same as the assembly center of the irregularly shaped and eccentric product. Due to spatial dimensions, it is impossible to accurately adjust it to the assembly center during the assembly process, resulting in inaccurate product precision, large product center of mass offset, and failure to meet design requirements. In the actual assembly process, the cone will inevitably wobble and rotate, making it impossible to align the shell and the cone in each quadrant area. It is necessary to lift the cone multiple times to align it with the assembly center. This method is inefficient, costly, risky, and has low accuracy. Summary of the Invention

[0004] To address the shortcomings of related technologies, this application provides a device and method for controlling the assembly accuracy of irregularly shaped eccentric products. The device guides the conical head of the cone to slide until the center of the cone coincides with the assembly center. At the same time, the positioning component restricts the movement direction of the cone to avoid relative rotation and / or relative oscillation between the cone and the housing.

[0005] On one hand, this application provides a device and method for controlling the assembly accuracy of irregularly shaped eccentric products. The irregularly shaped eccentric product includes a shell and a conical body. The shell is open at both ends and hollow inside. One end of the conical body is provided with a conical head. The device for controlling the assembly accuracy of irregularly shaped eccentric products includes:

[0006] A guide member is provided at one end of the housing. The guide member is open at both ends and has a through hole between the two ends. The inner diameter of the through hole gradually decreases from one end near the housing to the other end. The guide member is used to guide the conical head to slide through the through hole until the center of the conical body coincides with the assembly center.

[0007] A positioning component is connected to the cone and passes through the housing. The positioning component is used to ensure that the cone and the housing have at least one relative positioning point, thereby preventing relative rotation and / or relative swaying between the cone and the housing.

[0008] In some embodiments, the guide further includes:

[0009] A connecting part, wherein the outer diameter of the connecting part is not greater than the inner diameter of the housing, and the connecting part is used to connect with the housing;

[0010] The stabilizing part has an outer diameter not less than the inner diameter of the housing. The stabilizing part is connected to the connecting part. The through hole is provided in the stabilizing part and the connecting part. The inner diameter of the through hole gradually decreases from the connecting part to the stabilizing part, and the maximum inner diameter of the through hole is not greater than the maximum outer diameter of the conical head.

[0011] In some embodiments, the housing and the connecting portion are provided with a plurality of corresponding connecting holes, and the device for controlling the assembly accuracy of irregularly shaped eccentric products further includes:

[0012] Fasteners are inserted into the connecting holes on the housing and the connecting portion to fix the relative positions of the housing and the connecting portion.

[0013] In some embodiments, the positioning component includes:

[0014] A carrier is located at the other end of the cone-shaped body relative to the conical head, and the carrier is detachably connected to the cone-shaped body;

[0015] A positioning rod is provided, which passes through the carrier and the housing. The positioning rod, through the carrier, ensures that the cone and the housing have at least one relative positioning point, thereby preventing the cone from rotating relative to the housing.

[0016] In some embodiments, the positioning component further includes:

[0017] A connector is disposed inside the housing and is threadedly connected to the positioning rod;

[0018] Two rotating plates are disposed on the connecting member based on a pivot point and cross-rotation.

[0019] When the positioning rod rotates relative to the connector, it simultaneously pushes the two rotating plates along its axial direction, and the included angle between the two rotating plates increases accordingly, thereby fixing one end of the positioning rod inside the housing.

[0020] In some embodiments, the positioning component further includes:

[0021] An elastic element is connected to the second rotating plate, and the elastic element is located on the other side of the rotating point relative to the positioning rod.

[0022] In some embodiments, the positioning component further includes:

[0023] A stop is sleeved on the positioning rod and is used to press the carrier and the housing together.

[0024] In some embodiments, the end of the positioning rod that is relatively far from the housing is provided with an adapter.

[0025] In some embodiments, the device for controlling the assembly accuracy of irregularly shaped eccentric products further includes:

[0026] A lifting hole is provided on the carrier, and the lifting hole is used to connect a lifting device so that the lifting device can lift the conical body through the carrier for assembly.

[0027] On the other hand, an assembly method is also provided, which uses the assembly accuracy control device for irregularly shaped eccentric products according to any one of claims 1-9 for assembly, comprising:

[0028] Preparation steps: Connect the positioning component to the cone-shaped body, lift the cone-shaped body using a hoisting device, and install the guide and the positioning component opposite to each other at both ends of the housing;

[0029] In the assembly step, the cone is inserted into the housing along the axial direction of the cone based on the limitation of the positioning component, and at the same time, the cone center is aligned with the assembly center based on the guidance of the guide.

[0030] In the disassembly step, after the cone-shaped body is installed into the housing, the positioning component is removed. After fixing the relative position of the housing and the cone-shaped body, the guide is removed, thereby completing the assembly.

[0031] In summary, this application provides a device and method for controlling the assembly accuracy of irregularly shaped eccentric products. A guide member guides the conical head of a cone to slide until the center of the cone coincides with the assembly center. Simultaneously, a positioning component restricts the movement direction of the cone to prevent relative rotation and / or relative oscillation between the cone and the housing. The positioning rod, connecting member, and two rotating plates work together to quickly install or remove the positioning rod from the housing. An elastic element allows the two rotating plates to quickly reset, facilitating rapid removal of the positioning rod from outside the housing.

Figure 7 This is a general flowchart of the assembly method for the assembly accuracy control device for irregularly shaped eccentric products according to this application; specific embodiments are described below with reference to the above-mentioned figures.

[0049] Reference Appendix Figures 1 to 4This application provides a device for controlling the assembly accuracy of irregularly shaped eccentric products. The irregularly shaped eccentric product includes a housing 100 and a conical body 200. The housing 100 is open at both ends and hollow inside. One end of the conical body 200 is provided with a conical head. The device for controlling the assembly accuracy of irregularly shaped eccentric products includes a guide 300 and a positioning component 400. The guide 300 is located at one end of the housing 100. The guide 300 is open at both ends and has a through hole between the two ends. The inner diameter of the through hole gradually decreases from one end near the housing 100 to the other end. The guide 300 is used to guide the conical head to slide through the through hole until the center of the conical body 200 coincides with the assembly center. The positioning component 400 is connected to the conical body 200 and is disposed on the housing 100. The positioning component 400 is used to ensure that there is at least one relative positioning point between the conical body 200 and the housing 100, thereby avoiding relative rotation and / or relative oscillation between the conical body 200 and the housing 100.

[0050] Reference Appendix Figure 5 In some embodiments, the guide 300 further includes a connecting portion 301 and a stabilizing portion 302; wherein the outer diameter of the connecting portion 301 is not greater than the inner diameter of the housing 100, and the connecting portion 301 is used to connect with the housing 100; the outer diameter of the stabilizing portion 302 is not less than the inner diameter of the housing 100, the stabilizing portion 302 is connected to the connecting portion 301, a through hole is provided in the stabilizing portion 302 and the connecting portion 301, the inner diameter of the through hole gradually decreases from the connecting portion 301 to the stabilizing portion 302, and the maximum inner diameter of the through hole is not greater than the maximum outer diameter of the conical head.

[0051] Specifically, the outer diameter of the connecting part 301 matches the inner diameter of the housing 100. The size of the inner diameter of the connecting part 301 depends on the inner diameter of the through hole and is never greater than the maximum outer diameter of the conical head, so that the conical head of the cone 200 cannot completely pass through the connecting part 301. One end of the connecting part 301 is connected to the stabilizing part 302. The outer diameter of the stabilizing part 302 is greater than the outer diameter of the connecting part 301 to form a stepped structure. The stepped structure is used to abut against one end of the housing 100, thereby stabilizing the relative position of the guide 300 and the housing 100. The through hole is provided in the stabilizing part 302 and the connecting part 301. The inner diameter of the through hole gradually decreases from the connecting part 301 to the stabilizing part 302, and is used to guide the conical head of the cone 200 to slide to the assembly center so that the center of the cone 200 coincides with the assembly center, thereby achieving the assembly requirements.

[0052] It should be noted that the assembly center is defined as the ideal center point required during product assembly. This point is the reference point for all related components or parts to be aligned and positioned during assembly. In fact, the assembly center is the key position to ensure that the various parts can be correctly and accurately connected and combined together. However, the irregularly shaped and eccentric product to be assembled in this application has a housing 100 designed based on market demand and fitted with an irregular curve. Therefore, the center of the housing 100 is not consistent with the assembly center. This application uses the guide 300 to directly guide the center of the conical body 200 to coincide with the assembly center, avoiding the need to raise and lower the conical body 200 multiple times to align with the assembly center during the assembly process, thereby improving assembly efficiency and assembly accuracy.

[0053] In some embodiments, the housing 100 and the connecting portion 301 are provided with a plurality of corresponding connecting holes, and fasteners are inserted into the connecting holes on the housing 100 and the connecting portion 301 to fix the relative position of the housing 100 and the connecting portion 301.

[0054] Specifically, the fasteners include, but are not limited to, screws, bolts and pins. The fasteners are used to prevent relative movement between the housing 100 and the connecting part 301, thereby ensuring relative stability between the guide 300 and the housing 100 during the assembly process, thereby improving the assembly accuracy.

[0055] Reference Appendix Figures 1 to 4 In some embodiments, the positioning assembly 400 includes a carrier 401 and a positioning rod 402; wherein the carrier 401 is located at the other end of the cone 200 relative to the conical head, the carrier 401 and the cone 200 are detachably connected, the positioning rod 402 passes through the carrier 401 and the housing 100, and the positioning rod 402, through the carrier 401, ensures that the cone 200 and the housing 100 have at least one relative positioning point, thereby preventing the cone 200 and the housing 100 from rotating relative to each other; a lifting hole is provided on the carrier 401, and the lifting hole is used to connect a lifting device so that the lifting device can lift the cone 200 through the carrier 401 for assembly.

[0056] Specifically, the carrier 401 is provided with a fixing hole, a first auxiliary hole and a lifting hole; wherein, the fixing hole is used to connect and fix the cone 200, the first auxiliary hole is used for auxiliary positioning, and the lifting hole is used to connect a lifting device so that the lifting device can lift the cone 200 through the carrier 401 for assembly.

[0057] Reference Appendix Figure 1 and Figure 4In some embodiments, the housing 100 is provided with a second auxiliary hole corresponding to the first auxiliary hole, and the positioning rod 402 is provided in the first auxiliary hole and the second auxiliary hole, so that the cone 200 and the housing 100 have at least one relative positioning point. That is, during the process of the cone 200 being installed into the housing 100, the cone 200 can only move into the housing 100 along the axial direction of the cone 200, so as to avoid the cone 200 swinging relative to the housing 100 and / or rotating relative to the housing 100.

[0058] Reference Appendix Figure 1 , Figure 4 as well as Figure 6 In some embodiments, the positioning assembly 400 further includes a connector 403 and two rotating plates 404. The connector 403 is disposed inside the housing 100 and is threadedly connected to the positioning rod 402. The two rotating plates 404 are disposed on the connector 403 based on a pivot point and rotate crosswise. When the positioning rod 402 rotates relative to the connector 403, the positioning rod 402 simultaneously pushes the two rotating plates 404 along its axial direction, and the included angle of the two rotating plates 404 increases accordingly, thereby fixing one end of the positioning rod 402 inside the housing 100.

[0059] Specifically, the connector 403 is located at one end of the positioning rod 402. The connector 403 has an internal thread. The positioning rod 402 is threadedly connected to the connector 403. The two rotating plates 404 are cross-rotated on the connector 403 based on a pivot point. After the positioning rod 402 drives the connector 403 and the two rotating plates 404 to pass through the first auxiliary hole and the second auxiliary hole and enter the housing 100, as the positioning rod 402 is relatively screwed into the connector 403, the positioning rod 402 pushes the two rotating plates 404 to rotate and open relative to each other along its axial direction. The included angle of the two rotating plates 404 increases accordingly. After the two rotating plates 404 abut against the inner wall of the housing 100, one end of the positioning rod 402 is fixed inside the housing 100.

[0060] In some embodiments, the end of the positioning rod 402 that is relatively far from the housing 100 is provided with an adapter. The adapter includes, but is not limited to, square head, hexagonal head, octagonal head and star head. The adapter is used to connect to the corresponding wrench, so that the operator can rotate the positioning rod 402 outside the housing 100 by means of the wrench.

[0061] Reference Appendix Figure 6In some embodiments, the two rotating plates 404 are respectively provided with bosses, and the positioning assembly 400 also includes an elastic element 405. The elastic element 405 is connected to the two rotating plates 404 through the bosses. The elastic element 405 is located on the other side of the turning point relative to the positioning rod 402. The elastic element 405 includes, but is not limited to, springs, compression springs, and rubber. As the positioning rod 402 rotates out of the connecting piece 403, the elastic element 405 pulls the two rotating plates 404 to rotate and reset relative to each other. The included angle of the two rotating plates 404 decreases accordingly. After the included angle of the two rotating plates 404 is reduced to a preset angle, the fixing restriction on the positioning rod 402 and the housing 100 is released. The positioning rod 402 can be taken out from the housing 100 through the second auxiliary hole and the first auxiliary hole, thereby improving the disassembly efficiency.

[0062] Reference Appendix Figure 1 and Figure 4 In some embodiments, the positioning assembly 400 further includes a stop 406, which is sleeved on the positioning rod 402 and is used to press the carrier 401 against the housing 100.

[0063] Specifically, after the positioning rod 402 is installed into the housing 100 and the second rotating frame is opened, the stop 406 is pressed into the first auxiliary hole, thereby filling the gap between the positioning rod 402 and the first auxiliary hole, and pressing the positioning rod 402 against the inner wall of the housing 100, further fixing the positioning rod 402. Specific Implementation Example 2

[0065] Reference Appendix Figure 7 This application also provides a control method, which uses the assembly accuracy control device for irregularly shaped eccentric products in the above specific embodiment 1 for assembly, including preparation step S1, assembly step S2 and disassembly step S3.

[0066] In some embodiments, preparation step S1 includes connecting the positioning component 400 to the cone 200, lifting the cone 200 using a hoisting device, and mounting the guide 300 and the positioning component 400 opposite to each other at both ends of the housing 100.

[0067] Specifically, the carrier 401 is fixedly connected to the end of the cone 200 furthest from the cone head; the guide 300 is mounted on the end of the housing 100 with the smaller opening, and the guide 300 is connected and fixed to the housing 100 with fasteners, so that the housing 100 is placed above the guide 300; the cone 200 is lifted to the end of the housing 100 with the larger opening using a hoisting device, and a coordinate system is established based on a plane perpendicular to the axial direction of the cone 200 to divide the cone 200 and the housing 100 into corresponding quadrants, and a coarse coordinate system is established. After aligning the quadrants, the positioning rod 402, connecting piece 403, and second rotating plate 404 pass through the carrier 401 and housing 100 via the first auxiliary hole and the second auxiliary hole. By rotating the positioning rod 402 relative to the connecting piece 403, the second rotating plate 404 is pushed open, and the included angle of the second rotating plate 404 increases until the second rotating plate 404 abuts against the inner wall of the housing 100. The stop piece 406 is pressed into the first auxiliary hole, so that the positioning rod 402 is pressed tightly against the inner wall of the housing 100, thereby fixing the positioning rod 402 to the housing 100.

[0068] It should be noted that the end with the larger opening of the housing 100 is usually the end where the conical body 200 enters the housing 100, and the end with the smaller opening of the housing 100 is usually the end where the conical head of the conical body 200 extends out of the housing 100. In the actual assembly process, the end where the conical body 200 enters the housing 100 and the end where the conical head extends out of the housing 100 should be selected according to the actual situation, and it is not necessary to compare the size of the opening of the housing 100 to make the selection.

[0069] In some embodiments, assembly step S2 includes inserting the cone 200 into the housing 100 along the axial direction of the cone 200 based on the constraint of the positioning component 400, while the center of the cone 200 coincides with the assembly center based on the guidance of the guide 300.

[0070] Specifically, the lifting equipment controls the cone 200 to be lowered into the housing 100. Based on the positioning rod 402, the cone 200 is installed into the housing 100 along the axial direction of the cone 200, which prevents the cone 200 from swinging or rotating relative to the housing 100 during the installation process, so that the corresponding quadrants are accurately aligned. At the same time, the guide 300 guides the conical head of the cone 200 to slide to the preset position, so that the center of the cone 200 coincides with the assembly center. After the end face of the carrier 401 is flush with the end face of the housing 100, the operation of installing the cone 200 into the housing 100 is completed.

[0071] In some embodiments, disassembly step S3 includes removing the positioning component 400 after the conical body 200 is inserted into the housing 100, and removing the guide 300 after fixing the relative position of the housing 100 and the conical body 200, thereby completing the assembly.

[0072] Specifically, after the cone 200 is installed into the housing 100, the stop 406 is removed from the first auxiliary hole. The positioning rod 402 is rotated relative to the connecting member 403 to unscrew it. The elastic member 405 pulls the second rotating plate 404 to close and reset, and the included angle of the two rotating plates 404 decreases until the restriction of the positioning rod 402 along its axial direction by the two rotating plates 404 is released, and the positioning rod 402 can be removed. After the connection between the carrier 401 and the cone 200 is released and the carrier 401 is removed, the relative position of the cone 200 and the housing 100 is fixed, and the housing 100 is tilted to remove the guide member 300 at its bottom, thereby completing the assembly.

[0073] This application provides a device and method for controlling the assembly accuracy of irregularly shaped eccentric products. A guide member 300 guides the conical head of a conical body 200 to slide until the center of the conical body 200 coincides with the assembly center. Simultaneously, a positioning component 400 restricts the movement direction of the conical body 200 to prevent relative rotation and / or relative oscillation between the conical body 200 and the housing 100. The positioning rod 402, connecting member 403, and two rotating plates 404 work together to quickly install or remove the positioning rod 402 from the housing 100. An elastic member 405 allows the two rotating plates 404 to quickly reset, facilitating rapid removal of the positioning rod 402 from outside the housing 100.

[0074] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0075] The above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in this application.
