Description

Technical Field

[0001] The utility model relates to the technical field of riveting tools, in particular to a shell riveting clamp. Background Art

[0002] In the field of riveting technology, especially in the manufacturing process involving precision parts such as carbon canister valve assemblies, the design and use of riveting fixtures are crucial. Traditional riveting methods often make it difficult to accurately control the position and shape of the riveting points, resulting in the flatness and riveting depth of the riveted parts failing to meet the design requirements, which in turn affects the overall performance and consistency of the product.

[0003] For the canister valve assembly, the riveting process between the skeleton winding assembly and the iron parts is particularly critical. In this process, the flatness of the iron parts needs to be strictly controlled to ensure the consistency of the assembly flow. However, in actual operation, due to insufficient design or improper operation of the riveting fixture, the riveting points often bulge out, which not only destroys the flatness of the iron parts, but also may affect the sealing and flow control accuracy of the assembly.

[0004] On the other hand, the riveting depth of the static iron core is also an important factor affecting the performance of the carbon canister valve assembly. Ideally, the riveting depth of the static iron core should be kept within a specific range (such as 13.20mm) to ensure the electromagnetic performance and stability of the assembly. However, due to the poor consistency of the pre-installed dimensions and the lack of precise control during the riveting process, the riveting depth of the static iron core is often difficult to guarantee, resulting in a large error in the assembly flow rate, increasing the defective rate and production costs.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a shell riveting fixture, such as Figure 1-Figure 3 As shown, it includes a base 14, two guide columns 3 are installed on the top of one side of the base 14, an upper mounting base 1 is installed on the upper end of the guide column 3, an upper fixing plate 2 is installed on the bottom of the upper mounting base 1, a lower fixing plate 5 is installed on the bottom end of the guide column 3, an upper positioning plate 6 is installed on the bottom of the upper fixing plate 2, a lower positioning plate 4 is installed on the top of the lower fixing plate 5, a lubrication sleeve positioning column 8 and a lower magnetic plate positioning column 9 are installed on the top of the lower fixing plate 5, and a skeleton winding assembly is arranged on the upper part of the lower positioning plate 4.

[0024] In this embodiment, positioning columns are installed on both the upper fixing plate 2 and the lower fixing plate 5. The upper fixing plate 2 is connected to the holes of the upper positioning plate 6 through the positioning columns, and the lower fixing plate 5 is connected to the holes of the lower positioning plate 4 through the positioning columns. Such a design ensures the accurate positioning of the skeleton winding assembly and the shell iron parts during the riveting process.

[0025] Specifically, a plurality of turning pins 7 are installed in the middle of the upper fixing plate 2 and the lower fixing plate 5, and the turning pins 7 are arranged in a ring. Such a design enables the turning pins 7 to contact the iron parts evenly when the upper and lower positioning plates are pressed down, effectively preventing the occurrence of the convex phenomenon of the riveting point.

[0026] Furthermore, the skeleton winding assembly includes a magnetic housing 12, a lower magnetic plate 13 is installed at the bottom of the magnetic housing 12, a lubricating sleeve 11 is arranged in the middle of the lower magnetic plate 13, and the top end of the lubricating sleeve positioning column 8 is engaged with the lubricating sleeve 11. Such a design enables the clamp to accurately control the riveting depth of the static iron core.

[0027] Furthermore, a plurality of positioning holes are provided on the surface of the lower magnetic conductive plate 13, and the top end of the lower magnetic conductive plate positioning column 9 passes through the lower positioning plate 4 and is engaged with the positioning holes of the lower magnetic conductive plate 13. Such a design further enhances the positioning accuracy of the fixture.

[0028] A static iron core 10 is installed in the middle of the magnetic conductive housing 12. The riveting depth of the static iron core is an important factor affecting the performance of the carbon canister valve assembly. The utility model ensures the electromagnetic performance and stability of the assembly by accurately controlling the riveting depth.

[0029] Furthermore, a plurality of protrusions are provided at the outer bottom of the magnetic shell 12, and a plurality of notches are provided at the outer side of the lower magnetic plate 13, and the protrusions and notches are engaged with each other. Such a design enables the magnetic shell and the lower magnetic plate to be closely matched, thereby improving the precision of riveting.

[0030] Furthermore, a plurality of through holes are provided on the surface of the magnetically conductive housing 12. These through holes can be used for heat dissipation or weight reduction.

[0031] When the housing riveting fixture of the utility model is used, the skeleton winding assembly is first accurately assembled onto the lower fixing plate 5. In this step, the lubricating sleeve positioning column 8 is snap-fitted with the lubricating sleeve 11, and the top end of the lower magnetic plate positioning column 9 passes through the lower positioning plate 4 and snap-fitted with the positioning hole of the lower magnetic plate 13, ensuring the accurate positioning of the skeleton winding assembly.

[0032] Next, the operator places the entire fixture on the fully automatic riveting machine and fixes the upper mounting base 1 on the machine. At this point, the fixture is ready and waiting for the riveting operation. When the fully automatic riveting machine is started, the upper fixed plate 2 moves downward under the drive of the machine, and at the same time drives the upper positioning plate 6 to press down. In this process, the turning needles 7 installed in the middle of the upper fixed plate 2 and the lower fixed plate 5 will also be pressed down. Their annular arrangement design enables the turning needles 7 to contact the iron parts evenly. As the upper positioning plate 6 continues to be pressed down, the turning needles 7 rivet the iron parts to the outer shell of the skeleton winding assembly. Due to the uniform contact design of the turning needles 7, the occurrence of convexity of the riveting points is effectively prevented, ensuring the quality and stability of the riveting.

[0033] After riveting is completed, the upper fixing plate 2 and the upper positioning plate 6 are driven by the machine to return to their original positions. At this time, the operator can remove the riveted product from the fixture and proceed to the next round of production operations.
