The required force value usually has an interval value requirement, which requires manual coordination, and high requirements for interchangeability, worker experience and fast operation.
[0003] Existing riveting and flaring assemblies are mostly mechanical and single-type, with a lot of manual operations, and the usage space or scenes are all point-to-point, resulting in a large number of tools involved in each section and part, and extremely low recognition. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0023] On the contrary, this application covers any alternatives, modifications, equivalents, and solutions made within the spirit and scope of this application as defined by the claims. Furthermore, to facilitate a better understanding of this application, certain specific details are described in detail below in the detailed description of this application. Those skilled in the art will be able to fully understand this application without these details.
[0024] Example 1
[0025] like Figure 1-3 As shown, a specified track extrusion expansion assembly fixture includes a base 1, a mating extrusion component, a guide rail 2 component, a guide rail head 8, and an expander 5.
[0026] A guide rail assembly 2 is mounted on the base 1. The guide rail assembly 2 includes a guide rail 2 with two movable sliders 3 disposed thereon. The sliders 3 can move toward or away from each other, with a guide rail head 8 disposed between the sliders 3. A spring 9 is disposed between the sliders 3. The surfaces where the sliders 3 contact the guide rail head 8 are inclined, and the surfaces where the guide rail head 8 contacts the sliders 3 are also inclined.
[0027] The guide rail head 8 is connected to the driving assembly, which drives the guide rail head 8 to move vertically.
[0028] In this embodiment, the driving assembly includes a rotating handle 6. A through hole is provided on the guide rail head 8 for the rotating shaft of the rotating handle 6 to pass through. The rotating handle 6 is threadedly connected to the base 1. The bottom of the rotating handle 6 abuts against the upper surface of the guide rail head 8.
[0029] Both sliders 3 are provided with expanders 5 , and the surface of the expander 5 in contact with the component 4 is an arc surface.
[0030] In addition, the driving component can also be any structure that applies vertical force to the guide rail head 8, such as an electric push rod, a cylinder, etc.
[0031] Preferably, the expander 5 is a vertical columnar structure.
[0032] During use, the two parts 4 are placed together on the expander 5, and the rotating handle 6 is rotated. The rotating handle 6 drives the guide rail head 8 downward, squeezing the sliders 3 to generate a thrust, causing the two sliders 3 to move in opposite directions, and the distance between the two expanders 5 is widened, thereby completing the expansion and assembly of the parts 4. The spring 9 is provided so that when a universal torque is applied to the rotating handle 6, the spring 9 generates a pulling force, causing the sliders 3 to return to their original position and maintain contact with the guide rail head 8.
[0033] In this embodiment, in actual application, the plastic deformation capacity of one part 4 is greater than that of the other part 4 .
[0034] In this embodiment, the expanding force is applied by the threaded connection of the rotating handle 6 and the guide rail head 8. By controlling the number of rotations, the displacement accuracy of the slider 3 can be precisely controlled, thereby achieving higher expansion accuracy. By intermittently rotating the rotating handle 6, the expander 5 is caused to reciprocate continuously, thereby achieving expansion.
[0035] In this embodiment, a base 1 is provided to support the extrusion assembly and the guide rail 2 assembly. The contact surfaces of the guide rail 2 assembly and the slider 3 with the guide rail head 8 are configured as inclined surfaces to adjust the spacing between the two sliders 3. A flare 5 is provided to allow flaring during the reciprocating linear motion. In this embodiment, a spring 9 is provided to generate a pulling force, causing the two sliders 3 to abut the guide rail head 8, thereby causing the sliders 3 to move downward when the rotating handle 6 is rotated.
[0036] As a preferred embodiment, the bottom of the base 1 is hollow, and the rotating shaft of the rotating handle 6 passes through the base 1 .
[0037] Example 2
[0038] In this embodiment, there are two sets of guide rail 2 assemblies, which are arranged opposite each other. Each set of guide rail 2 assemblies has two guide rails 2, which are bolted to the base 1. Sliders 3 are provided with chute grooves on both sides, through which the two guide rails 2 are slidably connected to the two sides of the slides 3.
[0039] Furthermore, a limit plate 7 is provided between the two guide rails 2 to limit the displacement range of the slider 3. The slider 3 is divided into a first region and a second region. The first region is slidably connected to the guide rails 2, and the second region is provided with the expander 5. The upper surface of the second region is lower than that of the first region, preventing the first region from passing through the limit plate 7. Simultaneously, the expander 5 also cannot pass through the limit plate 7. In other words, the limit plate 7 is located between the expander 5 and the first region, and above the second region.
[0040] Since the guide rails 2 are connected to the base 1 by bolts, the distance between the two guide rail 2 components can be adjusted to match parts 4 of different sizes.
[0041] It is worth noting that, based on the above structural design, in order to solve the same technical problem, even if some insubstantial improvements are made on the basis of the present invention, they also fall within the scope of protection of the present invention.
