Description

Technical Field

[0001] This utility model relates to the field of riveting fixture technology, specifically a riveting fixture for button assembly. Background Technology

[0002] Riveting fixtures for key assembly are specialized tooling used in the key assembly process. They are mainly used to reliably rivet and fix key components such as keycaps, springs, and brackets, thereby ensuring the precision and consistency of key assembly, adapting to the needs of mass production, reducing assembly problems caused by differences in manual operation, and ensuring the quality stability and production efficiency of finished key products.

[0003] Utility model patent CN220717695U discloses a button riveting device for electronic gear shift assembly processing. The device includes a base with symmetrically arranged side frames. A cover plate is mounted on the top of the side frames, and a riveting assembly is mounted on the cover plate. The riveting assembly includes a riveting cylinder mounted on the cover plate, a riveting seat at the output end of the riveting cylinder, located below the cover plate, and a top plate at the bottom of the riveting seat. Multiple connecting rods are arranged at the corners of the bottom surface of the top plate, and a moving mold is mounted on each connecting rod. The moving mold slides with the connecting rods. High-strength springs are mounted on the connecting rods in a crisscross pattern, with both ends of the high-strength springs abutting against the top plate and the moving mold, respectively. The riveting cylinder drives the riveting seat downwards, and the top plate acts on the moving mold, causing the moving mold to engage with the mold base, compressing the high-strength springs. The high-strength springs can instantly provide further high-strength elastic pressure, which then acts on the moving mold, achieving secondary extrusion, improving the riveting effect, and enhancing product quality.

[0004] In the aforementioned prior art, it is inconvenient to pre-position the buttons during the button riveting process, and workpiece offset and movement can occur during riveting, which will affect the riveting effect. Therefore, improvements are needed. Utility Model Content

[0023] Please see Figure 1 , Figure 2 , Figure 3 The positioning mechanism 8 includes a connecting sleeve 81, which is slidably sleeved inside the fixed base 10. A guide rod 82 is slidably sleeved inside the connecting sleeve 81 and fixedly connected to the fixed base 10. A connecting rod 83 is fixedly connected inside the connecting sleeve 81. A first spring 84 is provided on the outside of the connecting rod 83. One end of the first spring 84 is fixedly connected to the connecting sleeve 81, and the other end of the first spring 84 is fixedly connected to the connecting rod 85. By designing the first spring 84, the force of the first spring 84 can act on the connecting rod 85. A connecting rod 85 is slidably sleeved on the outside of the connecting rod 83. A pressure block 86 is fixedly connected to the bottom of the connecting rod 85. A ball bearing 87 is movably sleeved inside the connecting rod 85 and slidably connected to the connecting sleeve 81. A groove 88 is provided inside the connecting sleeve 81, and the ball bearing 87 is slidably connected inside the groove 88. By designing the groove 88, the ball bearing 87 can slide along the groove 88. By designing the positioning mechanism 8, the workpiece can be pressed down and positioned.

[0024] Please see Figure 1 , Figure 2 , Figure 4The adjusting mechanism 9 includes a slot 91. A slot 91 is formed on the top of the inner wall of the fixed base 10. A ball 92 is movably fitted inside the slot 91. Multiple slots 91 are evenly distributed inside the fixed base 10. By designing multiple slots 91, the ball 92 can roll into different positions within the slots 91. A slide block 93 is movably fitted outside the ball 92. The slide block 93 is slidably connected to the fixed base 10 and fixedly connected to the connecting sleeve 81. A slider 94 is movably sleeved on the side, and the slider 94 is slidably connected to the slide block 93.

A second spring 96 is provided on the outside of the fixed rod 95, and the second spring 96 is fixedly connected to the slider 94. The other end of the second spring 96 is fixedly connected to the slide block 93. By designing the second spring 96, the force of the second spring 96 can be applied to the slider 94. By designing the adjustment mechanism 9, the position of the pressure block 86 can be easily adjusted.

[0025] The specific implementation process of this utility model is as follows: In use, the workpiece is first placed inside the fixed mold 4, and then the hydraulic cylinder 7 is started. The output end of the hydraulic cylinder 7 drives the fixed seat 10 to move down, and the fixed seat 10 drives the riveting head 12 to move down. At the same time, the fixed seat 10 also drives the connecting sleeve 81, the connecting rod 85 and the pressure block 86 to move down. The pressure block 86 will first contact the edge of the workpiece and stop moving, while the fixed seat 10 will drive the connecting sleeve 81 to continue to move down. The connecting sleeve 81 will drive the connecting rod 83 to move down along the connecting rod 85. The connecting sleeve 81 will press down the first spring 84. Under the elastic action of the first spring 84, it will give the connecting rod 85 a downward counter-force, which can make the pressure block 86 press the workpiece. The workpiece can be automatically assisted in positioning before riveting, making the stability of the workpiece during riveting higher and improving the riveting effect.

[0026] After the pressure block 86 presses down on the workpiece, the riveting head 12 moves down and contacts the workpiece, allowing for riveting. When the position of the pressure block 86 needs to be adjusted, the connecting sleeve 81 is pushed horizontally. The connecting sleeve 81 moves horizontally along the guide rod 82, and at the same time, the connecting sleeve 81 drives the retaining ball 92 to roll along the retaining groove 91. The retaining ball 92 is squeezed and rolls downwards, causing the slider 94 to slide along the fixed rod 95. The slider 94 can press down the second spring 96, allowing the retaining ball 92 to separate from the retaining groove 91. As the slide block 93 continues to move, the elasticity of the second spring 96 will give the slider 94 an upward thrust, allowing the retaining ball 92 to roll into the retaining groove 91 at another position. This allows the retaining ball 92 to be inserted and engaged with the retaining groove 91 at different positions, and the positioning and use position of the pressure block 86 can be flexibly adjusted to accommodate workpieces of different sizes for positioning and riveting.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
