As shown in Figures 1-4, the core bushing assembly tooling of the electric recliner of the automobile seat described in the embodiment of the present application includes a base plate 1, a floating plate 2, a guide mechanism 3, a first placement seat 4, a second placement seat 5 and a buffer mechanism 9. The guide mechanism 3 is provided with multiple groups, and the guide mechanism 3 includes a linear bearing 6 and a guide column 7. The linear bearing 6 is installed on the base plate 1. During linear motion, the linear bearing 6 has the advantages of small friction resistance, high precision, and fast movement. One end of the guide column 7 is connected to the linear bearing 6, and the other end of the guide column 7 is connected to the base plate 1. The first placement seat 4 is installed on the floating plate 2, and the second placement seat 5 is installed on the base plate 1. A accommodating cavity 8 is provided in the middle of the floating plate 2, and the second placement seat 5 extends into the accommodating cavity 8. There are at least two groups of buffer mechanisms 9, and the buffer mechanisms 9 are arranged between the base plate 1 and the floating plate 2.

When in use, the tooth plate is placed on the first placement seat 4, and the bushing is placed on the second placement seat 5, ensuring the accurate alignment between the tooth plate and the bushing, and then the tooth plate is pressed down by the pressing tool to make the floating plate 2 sink. While the floating plate 2 sinks, the buffer mechanism 9 is squeezed until the bushing is pressed into the tooth plate. In this process, the buffer mechanism 9 is compressed. After the pressing is completed, the pressing tool leaves the tooth plate, and the buffer mechanism 9 is reset, pushing the floating plate 2, the first placement seat 4 and the second placement seat 5 back to the initial position, and popping up the assembled product, so as to facilitate taking the product, after the tooth plate is placed on the first placement seat 4 and the bushing is placed on the second placement seat 5, the above-mentioned pressing process is repeated. The present application has a simple structure and can stably realize the press-fitting of the bushing, effectively avoiding the problems of inadequate press-fitting or crushing of the bushing, thereby improving the assembly efficiency between the bushing and the tooth plate.

In this embodiment, the buffer mechanism 9 includes a slide rod 10 and a spring 11. The bottom of the floating plate 2 has a plurality of guide grooves 12. One end of the slide rod 10 extends into the guide groove 12. The other end of the slide rod 10 is connected to the bottom plate 1. The spring 11 is sleeved on the slide rod 10. The slide rod 10 is used to ensure the stability of the spring 11 during use. One end of the spring 11 abuts against the bottom plate 1, and the other end of the spring 11 abuts against the floating plate 2.

During press-fitting, the press-fitting tool presses down the tooth plate, causing the floating plate 2 to sink. While the floating plate 2 sinks, the spring 11 is squeezed until the bushing is pressed into the tooth plate. In this process, the spring 11 is compressed. After the press-fitting is completed, the press-fitting tool leaves the tooth plate and the spring 11 rebounds, making it easy to pop up the assembled product, thereby making it convenient to take the product and improving work efficiency. After the spring 11 returns to its original state, the floating plate 2, the first placement seat 4 and the second placement seat 5 all return to their initial positions. After the tooth plate is placed on the first placement seat 4 and the bushing is placed on the second placement seat 5, the above press-fitting process is repeated.

In this embodiment, the first placement seat 4 is connected to the floating plate 2 by bolts, which is convenient for assembly and disassembly of the first placement seat 4 and the floating plate 2. The second placement seat 5 is connected to the bottom plate 1 by bolts, which is convenient for assembly and disassembly of the second placement seat 5 and the bottom plate 1.

In this embodiment, a base 13 is provided at the bottom of the bottom plate 1 , and the bottom plate 1 is installed on the operating table through the base 13 .

In this embodiment, the bottom plate 1 and the base 13 are connected by bolts, so that the bottom plate 1 and the base 13 can be easily assembled and disassembled.

In this embodiment, a handle 14 is provided on the base 13 , which facilitates the movement of the base 13 when the base 13 is installed on the operating table.

In this embodiment, the handle 14 and the base 13 are connected by bolts, so that the handle 14 and the base 13 can be easily assembled and disassembled.

The working principle of the core bushing assembly tooling of the electric recliner of a car seat in the embodiment of the present application is as follows:

A toothed plate is placed on the first placement seat 4, and a bushing is placed on the second placement seat 5, ensuring accurate alignment between the toothed plate and the bushing. The toothed plate is then pressed down by a pressing tool to cause the floating plate 2 to sink until the bushing is pressed into the toothed plate. During this process, the spring 11 is compressed. After the pressing is completed, the pressing tool leaves the toothed plate, and the spring 11 rebounds, making it easy to pop up the assembled product, thereby making it easier to take the product and improving work efficiency. After the spring 11 returns to its original state, the floating plate 2, the first placement seat 4, and the second placement seat 5 all return to their initial positions. After the toothed plate is placed on the first placement seat 4 and the bushing is placed on the second placement seat 5, the above pressing process is repeated.

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