Description

An angle adjuster core washer assembly fixture Technical Field

[0001] This application relates to the field of angle adjuster core washer assembly technology, and more specifically, to an angle adjuster core washer assembly tooling. Background Technology

[0002] An adjuster is a device installed on the car seat frame to adjust the seat back angle. The device generally consists of a backrest connecting plate, a seat connecting plate, a core component, a handwheel or adjustment handle, a return spring, and other components (in some low-cost seats, the backrest connecting plate and the seat connecting plate are generally integrated into the backrest frame and the seat frame).

[0003] Currently, the core gasket within a single core component is typically positioned using tooling and installed on a gear plate (the structure of the gear plate 4 is shown in Figure 3. One side of the gear plate 4 has an external gear 41, and the other side has an internal gear ring 42. The external gear 42 and the internal gear ring 42 are eccentrically positioned. The gear plate 4 has a mounting through hole 43. The side of the gear plate 4 with the internal gear ring 42 has a mounting groove 44 for connecting with the core gasket 5. The opening of the mounting groove 44 has an annular protrusion 45) using automated assembly methods. This automated assembly method significantly improves production efficiency.

[0004] However, the aforementioned automated assembly methods have revealed many serious problems in practical applications:

[0005] 1. When the core component of the seat adjuster is found to be defective during inspection, the core component is often already assembled, or even the seat adjuster is already installed on the car seat frame. Furthermore, the gear plate makes eccentric movement when the seat adjuster is working. This makes the replacement and repositioning of the core gasket extremely difficult. Especially when the seat adjuster is installed on the car seat frame, the repair personnel have to work in an extremely confined space, and the operating space is severely limited, making it difficult to replace the core gasket smoothly.

[0006] 2. Since the problematic core gasket cannot be effectively replaced, the core component or even the entire car seat frame has to be scrapped, which undoubtedly brings great economic losses to car manufacturers and after-sales service departments.

[0007] 3. Automated assembly equipment involves technologies from multiple fields such as mechanics, electrical engineering, electronics, and computers. Its structure is complex, and once the equipment malfunctions, it is difficult to repair. It requires professional technicians and specialized repair equipment, and the repair time is long, which can cause the production line to stop and affect the production schedule. Summary of the Invention

[0008] The purpose of this application is to provide an assembly tooling for the core gasket of an angle adjuster, which can solve the technical problems raised in the background art.

[0009] This application provides a tooling for assembling the core washer of an angle adjuster, including:

[0010] The fastener includes a connecting part and a fixing part fixed to one side of the connecting part, wherein the fixing part is provided with a groove adapted to the core washer on the side away from the connecting part;

[0011] A locking assembly, which cooperates with the connecting portion to lock the gear plate to the side of the fixing portion away from the connecting portion;

[0012] An extrusion assembly is used to cooperate with the connecting part to push the core washer placed in the slot toward the gear plate, so that the washer is assembled onto the gear plate.

[0013] Furthermore, the locking assembly includes a locking bolt and a pad, the connecting part is cylindrical, the connecting part is provided with a threaded hole adapted to the locking bolt, the threaded hole communicates with the slot, and the pad is movably sleeved on the locking bolt.

[0014] Furthermore, the extrusion assembly includes an extrusion member and an extrusion nut. The extrusion member has a sliding through hole adapted to the connecting part. The extrusion member is slidably disposed on the connecting part through the sliding through hole. Multiple extrusion parts are fixedly disposed on the side of the extrusion member near the fixing part. The multiple extrusion parts are arranged in a ring with equal spacing. The fixing part has an extrusion through hole corresponding to the extrusion part. The extrusion part can pass through the extrusion through hole and extend into the slot. The outer surface of the connecting part has a thread adapted to the extrusion nut. The extrusion nut is threadedly connected to the connecting part.

[0015] Furthermore, the pad is made of rubber.

[0016] Furthermore, the connecting part is evenly provided with a plurality of positioning teeth for positioning the gear plate along its circumference, and the positioning teeth are adapted to the internal gear ring of the gear plate.

[0017] Furthermore, the opening of the slot is provided with an annular relief portion, which is adapted to the annular protrusion of the gear plate.

[0018] The beneficial effects of this utility model are:

[0019] This utility model uses a manual assembly method to assemble the core washer. When a faulty adjusting device is found and the core washer needs to be replaced, the manual assembly method makes it easier to remove the core washer from the gear plate and replace it. Workers can directly operate tools such as tweezers and pliers to disassemble the core washer and reassemble it using the tooling of this application. The core washer is easy to replace, avoiding the problem of faulty adjusting devices being directly installed on the car seat frame due to poor assembly of the core components, which would affect subsequent replacement.

[0020] During manual assembly, workers can sense the resistance and flatness of the core washer during installation by touch. They can promptly detect whether the core washer is installed in place, whether there is any jamming or unevenness, etc. If a problem is found, it can be adjusted immediately to avoid installing the problematic core washer onto the gear plate. This reduces the probability of problems with the angle adjuster caused by poor installation of the core washer and lowers the risk of scrapping the core components or the car seat frame.

[0021] This utility model has a simple structure, is easier to maintain than automated assembly equipment, is easy to carry, and is highly flexible in operation. Attached Figure Description

[0035] Specific implementation examples:

[0036] As shown in Figures 1-4, this application provides a tooling for assembling the core washer of an angle adjuster, including a fixing component 1, a locking component 2, and a pressing component 3. The fixing component 1 includes a connecting part 11 and a fixing part 12 fixed to one side of the connecting part 11. The side of the fixing part 12 away from the connecting part 11 is provided with a slot 121 adapted to the core washer 5. The locking component 2 is used to cooperate with the connecting part 11 to lock the gear plate 4 to the side of the fixing part 12 away from the connecting part 11. The pressing component 3 is used to cooperate with the connecting part 11 to push the core washer 5 placed in the slot 121 toward the gear plate 4, so that the washer is assembled on the gear plate 4. The slot 121 can accurately position the core washer 5, so that the core washer 5 will not be displaced or tilted during the assembly process, ensuring that the core washer 5 can be accurately assembled onto the gear plate 4, greatly reducing the possibility of angle adjuster failure due to the assembly position deviation of the core washer 5, and improving the assembly quality and stability of the angle adjuster.

[0037] As shown in Figures 1, 2, and 4, the locking assembly 2 includes a locking bolt 21 and a pad 22. The connecting part 11 is cylindrical and has a threaded hole 111 that matches the locking bolt 21. The threaded hole 111 communicates with the slot 121. The pad 22 is movably fitted onto the locking bolt 21. By rotating the locking bolt 21, the locking bolt 21 is screwed into the threaded hole 111. As the locking bolt 21 is pushed forward, the pad 22 is driven and gradually approaches the gear plate 4, finally pressing the gear plate 4 tightly onto the fixing part 12, thus fixing the gear plate 4. The operation is simple.

[0038] As shown in Figures 1, 2, and 4, the extrusion assembly 3 includes an extrusion member 31 and an extrusion nut 32. The extrusion member 31 has a sliding through hole 311 adapted to the connecting part 11. The extrusion member 31 is slidably mounted on the connecting part 11 through the sliding through hole 311. Multiple extrusion parts 312 are fixed on the side of the extrusion member 31 near the fixing part 12. The multiple extrusion parts 312 are arranged in a ring with equal spacing. The fixing part 12 has an extrusion through hole 122 corresponding to the extrusion parts 312. The extrusion parts 312 can pass through the extrusion through hole 122 and extend into the slot 121. The outer surface of the connecting part 11 has a thread adapted to the extrusion nut 32. The extrusion nut 32 is threadedly connected to the connecting part 11. The multiple extrusion parts 312 are arranged in a ring with equal spacing, so that the extrusion member 31 can apply uniform pressure to the gasket when extruding it, ensuring that the gasket is subjected to balanced force during installation and will not tilt or shift, thus improving the accuracy and quality of assembly.

[0039] As shown in Figures 1, 2 and 4, the pad 22 is made of rubber. During the locking process, the pad 22 can act as a buffer, which can prevent the locking bolt 21 from directly contacting the gear plate 4, reduce damage to the surface of the gear plate 4, ensure the integrity and accuracy of the gear plate 4, and thus improve the overall quality and service life of the angle adjuster.

[0040] As shown in Figures 1, 2, and 4, the connecting part 11 is evenly provided with a plurality of positioning teeth 123 for positioning the gear plate 4. The positioning teeth 123 are adapted to the internal gear ring 42 of the gear plate 4. When assembling the core washer 5 of the angle adjuster using the tooling, the gear plate 4 is placed on the side of the fixing part 12 away from the connecting part 11. Since the connecting part 11 is evenly distributed with a plurality of positioning teeth 123 along its circumference, and these positioning teeth 123 are adapted to the size and shape of the internal gear ring 42 of the gear plate 4, during the placement process, the tooth groove of the internal gear ring 42 of the gear plate 4 can naturally engage with the positioning teeth 123, restricting the movement of the gear plate 4 in the circumferential direction and improving the positioning accuracy of the gear plate 4 in the tooling.

[0041] As shown in Figures 2 and 3, the opening of the slot 121 is provided with an annular clearance portion 124. The annular clearance portion 124 is adapted to the annular protrusion 45 of the gear plate 4. During the assembly of the core washer 5 of the angle adjuster, when the gear plate 4 is placed on the side of the fixing part 12 away from the connecting part 11, the annular protrusion 45 on the gear plate 4 will naturally align with the annular clearance portion 124 at the opening of the slot 121, thereby achieving the initial positioning of the gear plate 4 on the fixing part 12.

[0042] As shown in Figures 1-4, this application also provides a method for assembling the core washer 5 of the angle adjuster. The assembly is performed using the aforementioned assembly fixture for the core washer 5 of the angle adjuster. The assembly steps include:

[0043] S1: Insert the extrusion part 31 into the connecting part 11 and screw the extrusion nut 32 onto the connecting part 11 to form a pre-assembly. The extrusion part 312 of the extrusion part 31 can slide within the extrusion through hole 122.

[0044] S2: Insert the core washer 5 into the slot 121;

[0045] S3: Insert the annular protrusion 45 of the gear plate 4 into the annular relief portion 124 of the fixing portion 12, and make the internal gear ring 42 on the gear plate 4 mesh with the positioning tooth 123 on the connecting portion 11. Use the locking bolt 21 to pass through the pad 22 and the mounting through hole 43 on the gear plate 4, and screw the locking bolt 21 into the threaded hole 111 of the connecting portion 11 to fix the gear plate 4 on the connecting portion 11.

[0046] S4: Tighten the compression nut 32. The compression nut 32 pushes the compression member 31 to bring the compression member 31 closer to the fixing part 12. The compression part 312 on the compression member 31 passes through the compression through hole 122 and pushes the core washer 5 in the compression groove, so that the core washer 5 is installed in the mounting groove 44 of the gear plate 4. When the compression part 312 contacts the annular protrusion 45 of the gear plate, the core washer 5 is flush with the annular protrusion 45 of the gear plate 4, and the assembly is in place.

[0047] This application uses a manual assembly method to assemble the core washer 5. When a faulty adjuster is found and the core washer 5 needs to be replaced, the manual assembly method makes it easier to remove the core washer 5 from the gear plate 4 and replace it. Workers can directly operate tools such as tweezers and pliers to disassemble the core washer 5 and reassemble it using the tooling of this application. The replacement of the core washer 5 is convenient, avoiding the problem of the faulty adjuster being directly installed on the car seat frame due to poor assembly of the core component, which would affect subsequent replacement.

[0048] During manual assembly, workers can sense the resistance and flatness of the core washer 5 during installation by touch, and promptly detect whether the core washer 5 is installed in place, whether there is jamming or unevenness, etc. If a problem is found, it can be adjusted immediately to avoid installing the problematic core washer 5 onto the gear plate 4, thereby reducing the probability of problems with the angle adjuster caused by improper installation of the core washer 5 and reducing the risk of scrapping core components or car seat frames;

[0049] This application has a simple structure, is easier to maintain than automated assembly equipment, is easy to carry, and has strong operational flexibility.

[0050] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
