Description

Technical Field

[0001] The present application relates to the technical field of the assembly of the core washer of an angle adjuster. Specifically, it relates to an assembly tool for the core washer of an angle adjuster and an assembly method thereof. Background Art

[0002] An angle adjuster is a device installed on the seat frame of an automobile to realize the angle adjustment of the seat back. This device generally consists of components such as a backrest connection plate, a seat connection plate, a core component, a handwheel or an adjustment handle, a return spring, etc. (in some low-cost seats, generally, the backrest connection plate and the seat connection plate are integrated into the backrest frame and the seat frame).

[0003] Currently, the core washer within a single core component is usually positioned by means of a tooling and installed on a gear plate (the structure of the gear plate 4 is as Figure 3 shown. One side of the gear plate 4 is provided with an external gear 41, and the other side is provided with an internal tooth ring 42. The external gear 42 and the internal tooth ring 42 are eccentrically arranged. The gear plate 4 is provided with a mounting through hole 43. On the side of the gear plate 4 where the internal tooth ring 42 is located, there is a mounting groove 44 for connecting with the core washer 5. An annular protrusion 45 is provided at the opening of the mounting groove 44) by an automated device. This automated assembly method significantly improves the production efficiency.

[0004] However, the above-mentioned automated assembly method exposes many serious problems in the actual application process:

[0005] 1. When it is detected that there are defects in the core component of the angle adjuster, since the core component has often been assembled at this time, and even the angle adjuster has been installed on the automobile seat frame, and the gear plate makes an eccentric movement during the operation of the angle adjuster, this makes it extremely difficult to replace and position and assemble the core washer. Especially after the angle adjuster is installed on the automobile seat frame, the maintenance personnel need to operate in a very narrow space, and the operating space is severely limited, making it difficult to smoothly complete the replacement of the core washer;

[0006] 2. Since the defective core washer cannot be effectively replaced, only the core component or even the entire automobile seat frame has to be scrapped, which undoubtedly brings great economic losses to automobile manufacturing enterprises and after-sales maintenance departments;

[0007] 3. The automated assembly equipment involves technologies in multiple fields such as machinery, electricity, electronics, and computers, and has a complex structure. Once the equipment fails, it is difficult to repair. Professional technical personnel and special repair equipment are required, and the repair time is long, resulting in the shutdown of the production line and affecting the production progress.

[0041] Such as Figures 1-4 shown, the present application provides an assembling tooling for a core washer of an angle adjuster, including a fixing member 1, a locking assembly 2 and an extrusion assembly 3. Among them, the fixing member 1 includes a connecting portion 11 and a fixing portion 12 fixedly arranged on one side of the connecting portion 11. A card slot 121 adapted to the core washer 5 is provided on the side of the fixing portion 12 away from the connecting portion 11; the locking assembly 2 is used to cooperate with the connecting portion 11 to lock the gear plate 4 on the side of the fixing portion 12 away from the connecting portion 11; the extrusion assembly 3 is used to cooperate with the connecting portion 11 to push the core washer 5 placed in the card slot 121 towards the gear plate 4, so that the washer is assembled on the gear plate 4. The setting of the card 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 the angle adjuster malfunction caused by the assembly position deviation of the core washer 5, and improving the assembly quality and stability of the angle adjuster.

[0042] Such as Figure 1 、 Figure 2 and Figure 4As shown, the locking assembly 2 includes a locking bolt 21 and a spacer 22. The connecting portion 11 is cylindrical, and a threaded hole 111 adapted to the locking bolt 21 is provided on the connecting portion 11. The threaded hole 111 communicates with the card slot 121. The spacer 22 is movably sleeved on 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 advances, the spacer 22 is driven and gradually approaches the gear plate 4, and finally presses the gear plate 4 tightly against the fixing portion 12 to fix the gear plate 4. The operation method is simple.

[0043] As Figure 1 , Figure 2 and Figure 4 shown, the pressing assembly 3 includes a pressing member 31 and a pressing nut 32. A sliding through hole 311 adapted to the connecting portion 11 is provided on the pressing member 31. The pressing member 31 is slidably disposed on the connecting portion 11 through the sliding through hole 311. A plurality of pressing portions 312 are fixedly provided on one side of the pressing member 31 close to the fixing portion 12. The plurality of pressing portions 312 are arranged at equal intervals in a ring shape. Pressing through holes 122 corresponding to the pressing portions 312 are provided on the fixing portion 12. The pressing portions 312 can penetrate through the pressing through holes 122 and extend into the card slot 121. Threads adapted to the pressing nut 32 are provided on the outer surface of the connecting portion 11. The pressing nut 32 is threadedly connected to the connecting portion 11. The plurality of pressing portions 312 are arranged at equal intervals in a ring shape, so that when the pressing member 31 presses the washer, uniform pressure can be applied to the washer, ensuring that the washer is evenly stressed during the installation process and will not be tilted or offset, improving the assembly accuracy and quality.

[0044] As Figure 1 , Figure 2 and Figure 4 shown, the spacer 22 is made of rubber. During the locking process, the spacer 22 can play a buffering role, 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.

[0045] As Figure 1 , Figure 2 and Figure 4As shown, a plurality of positioning teeth 123 for positioning the gear plate 4 are uniformly arranged along the circumferential side of the connecting portion 11. The positioning teeth 123 are adapted to the internal tooth 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 portion 12 away from the connecting portion 11. Since a plurality of positioning teeth 123 are uniformly distributed along the circumferential side of the connecting portion 11, and these positioning teeth 123 are adapted to the internal tooth ring 42 of the gear plate 4 in terms of size and shape, during the placement process, the tooth grooves of the internal tooth 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.

[0046] As Figure 2 and Figure 3 shown, an annular relief portion 124 is provided at the opening of the card slot 121. The annular relief portion 124 is adapted to the annular protrusion 45 of the gear plate 4. During the assembly process of the core washer 5 of the angle adjuster, when the gear plate 4 is placed on the side of the fixing portion 12 away from the connecting portion 11, the annular protrusion 45 on the gear plate 4 will naturally align with the annular relief portion 124 at the opening of the card slot 121, achieving the preliminary positioning of the gear plate 4 on the fixing portion 12.

[0047] As Figures 1-4 shown, the present application also provides an assembly method for the core washer 5 of the angle adjuster. The assembly is carried out using the above-mentioned assembly tooling for the core washer 5 of the angle adjuster. The assembly steps include:

[0048] S1: Install the extrusion part 31 into the connecting portion 11, and screw the extrusion nut 32 onto the connecting portion 11 to form a pre-assembly. The extrusion part 312 of the extrusion part 31 can slide in the extrusion through-hole 122;

[0049] S2: Snap the core washer 5 into the card slot 121;

[0050] S3: Place the annular protrusion 45 of the gear plate 4 into the annular relief portion 124 of the fixing portion 12, and engage the internal tooth ring 42 on the gear plate 4 with the positioning teeth 123 on the connecting portion 11. Pass the locking bolt 21 through the spacer block 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;

[0051] S4: Turn the extrusion nut 32. The extrusion nut 32 pushes the extrusion part 31 to make the extrusion part 31 approach the fixing portion 12. The extrusion part 312 on the extrusion part 31 passes through the extrusion through-hole 122 to push the core washer 5 in the extrusion groove, so that the core washer 5 is installed into the mounting groove 44 of the gear plate 4. When the extrusion 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.

[0052] This application assembles the core washer 5 manually. When it is found that the core washer 5 needs to be replaced due to a defect in the angle adjuster, the manual assembly method can more conveniently remove the core washer 5 from the gear plate 4 and replace it. Workers can directly operate tools by hand, such as tweezers, pliers, etc., 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 direct installation of a problematic angle adjuster on the vehicle seat frame due to poor assembly of the core components, which affects subsequent replacement;

[0053] During the manual assembly process of this application, workers can sense the resistance, flatness, etc. when the core washer 5 is installed through the sense of touch, and promptly discover whether the core washer 5 is installed in place, whether there is jamming or unevenness, etc. If problems are found, adjustments can be made immediately to avoid installing a problematic core washer 5 on the gear plate 4, thereby reducing the probability of problems occurring in the angle adjuster due to poor installation of the core washer 5 and reducing the risk of scrapping of the core components or the vehicle seat frame;

[0054] This application has a simple structure. Compared with automated assembly equipment, it has less maintenance difficulty, is easy to carry, and has strong flexible operability.

[0055] The above are only the preferred embodiments of this application and are not intended to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
