Description

Technical Field

[0001] This utility model relates to the field of parts assembly technology, and more specifically, to an assembly device for flexible parts and metal parts. Background Technology

[0002] In modern manufacturing, especially in industries such as automotive, electronics, and home appliances, it is often necessary to precisely and reliably assemble flexible materials (such as rubber seals and plastic bushings) onto metal components (such as flanges, housings, and shaft parts). This press-fitting process between flexible materials and metal requires ensuring both tightness and sealing of the assembly without damaging the flexible components.

[0003] Traditional assembly methods often rely on manual operation or simple tooling fixtures. Manual operation typically involves using hand tools to hammer or press in components, which has many drawbacks: First, assembly efficiency is low, making it difficult to meet the cycle time requirements of automated production lines; second, assembly quality is unstable, relying entirely on the experience and skills of workers, and is prone to problems such as twisting, scratching, incomplete pressing, or excessive stretching of flexible parts due to uneven force or misalignment, resulting in a low product qualification rate.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0020] Example This utility model provides an assembly device for flexible parts and metal parts, such as... Figures 1-3 As shown, the device includes a fixed base 1 with an annular assembly opening 101 along its axial direction. A forming ring 2 is slidably disposed within the assembly opening 101 along its axial direction. A support block 3 is mounted on the outer wall of the fixed base 1. A load-bearing cover 4, coaxial with the assembly opening 101, is slidably disposed on the top of the support block 3. An adjustment structure 5 is provided on the support block 3 to drive the load-bearing cover 4 to move vertically. In use, the metal part 8 is placed in the assembly opening 101 of the fixed base 1 or on the forming ring 2. Then, the adjustment structure 5 drives the load-bearing cover 4 to move vertically and press it downwards against the workpiece. The forming ring 2 slides within the assembly opening 101, adjusting its position to match the pressure of the load-bearing cover 4. After pressing, the adjustment structure 5 lifts the load-bearing cover 4 and removes the assembled workpiece. In this structure, the fixed base 1 provides support and guidance, the forming ring 2 slides to adapt to the shape of the workpiece, and the load-bearing cover 4 applies vertical pressure, causing the flexible material 7 (such as rubber or plastic) to tightly bond with the metal part 8 under pressure. The adjustment structure 5 ensures that the position of the load-bearing cover 4 is adjustable, achieving precise press-fitting. The adjustment structure 5 also adjusts the height of the load-bearing cover 4 to adapt to workpieces of different sizes, improving the versatility of the device. The assembly port 101 is coaxially designed with the load-bearing cover 4 to ensure assembly alignment and improve assembly accuracy and consistency.

[0021] In some technical solutions of this utility model, the top of the forming ring 2 is provided with an annular assembly groove 201. The inner diameter of the assembly groove 201 on the side away from the fixed seat 1 gradually decreases along the axial direction of the forming ring 2 towards the fixed seat 1. The annular assembly groove 201 at the top of the forming ring 2 is used to place the flexible material 7. When the load-bearing cover 4 applies downward pressure to the metal component 8, the metal component 8 and the flexible material 7 are pressed into the assembly groove 201. As the inner radial direction of the assembly groove 201 gradually decreases towards the fixed seat 1, the material is compressed and guided, gradually fitting against the metal component 8. Through the geometric design of the tapered assembly groove 201, radial compressive force is generated, causing the flexible material 7 to deform and tightly wrap around the metal component 8. The tapered design of the groove guides the material flow, reduces assembly resistance, simplifies the introduction process of the flexible material 7, and improves assembly efficiency; ensures uniform deformation of the flexible material 7, reduces wrinkles or damage, and improves product quality; enhances the tightness of the metal component 8 and the flexible material 7 after assembly, and prevents loosening after assembly.

[0022] In some technical solutions of this utility model, an annular recess 202 is provided at the small-diameter end of the assembly groove 201. When the flexible material 7 is pressed into the assembly groove 201, the recess 202 at the small-diameter end accommodates excess material or provides buffer space. After the load-bearing cover 4 is pressed down, the material fills the recess 202, forming a more uniform shape. The recess 202 serves as a pressure relief zone, preventing excessive compression of the material and promoting uniform distribution of the material within the groove. By accommodating overflowing material, it reduces stress concentration, prevents damage to the flexible material 7 under high pressure, and improves product yield.

[0023] In some technical solutions of this utility model, a plurality of magnetic poles 203 are arranged circumferentially around the forming ring 2. The magnetic poles 203 in the forming ring 2 generate a magnetic field during assembly. The metal part 8 is attracted by the magnetism generated by the magnetic poles and fixed in the aligned position. When the load-bearing cover 4 is pressed down, the flexible material 7 and the metal part 8 are magnetically assisted to automatically position the metal part 8, preventing movement, reducing assembly errors caused by workpiece displacement, and improving consistency and efficiency.

[0024] In some technical solutions of this utility model, the adjusting structure 5 includes a cylinder structure 501 installed on the side wall of the support block 3. A connecting plate 502 is installed on the telescopic end of the cylinder structure 501, and the load-bearing cover 4 is connected to the connecting plate 502. Specifically, the adjusting structure 5 is a cylinder structure 501. The telescopic end of the cylinder drives the load-bearing cover 4 to move up and down through the connecting plate 502. During operation, controlling the cylinder to intake or exhaust air allows the load-bearing cover 4 to rise and fall quickly, ensuring precise pressure control, adapting to the assembly requirements of different materials, and facilitating later maintenance.

[0025] In some technical solutions of this utility model, a solenoid valve 6 connected to the air inlet of the cylinder structure 501 is installed on the side wall of the support block 3. The solenoid valve 6, installed on the side wall of the support block 3, controls the air inlet of the cylinder. The solenoid valve 6 is switched by an electrical signal, regulating the air intake and exhaust of the cylinder, thereby controlling the movement speed and position of the load-bearing cover 4, achieving automated control, reducing manual operation, and improving production efficiency; it also provides precise control of the movement of the load-bearing cover 4, enhancing assembly accuracy.

[0026] In some technical solutions of this utility model, a return spring 102 is installed inside the assembly port 101, and the free end of the return spring 102 abuts against the forming ring 2. The return spring 102 is installed inside the fixed base 1 and abuts against the forming ring 2. When the load-bearing cover 4 is pressed down, the forming ring 2 compresses the return spring 102; when the load-bearing cover 4 is lifted, the spring force pushes the forming ring 2 back to its initial position. This ensures that the forming ring 2 automatically returns to its origin after each assembly, maintaining a ready state. The spring buffers the pressure, reduces the impact of the load-bearing cover 4 on the forming ring 2, extends the life of the device, increases the device's cycle speed, reduces reset time, and improves production efficiency; it also ensures that the forming ring 2 is in the same position, improving assembly repeatability accuracy.

[0027] In some technical solutions of this utility model, a guide groove 103 is formed along the axial direction on the inner wall of the assembly port 101, and a slider 204 is provided on the outer wall of the forming ring 2, which is slidably connected to the guide groove 103. The guide groove 103 is formed on the inner wall of the fixed base 1, and the slider 204 is installed on the outer side of the forming ring 2. When the forming ring 2 slides, the slider 204 moves along the guide groove 103, restricting the forming ring 2 to move only along the axial direction, preventing rotation, thereby improving the stability and accuracy of the movement of the forming ring 2 and ensuring assembly quality.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
