Description

Technical Field

[0001] This utility model relates to the field of cookware manufacturing technology, and in particular to a rivet spraying fixture. Background Technology

[0002] Currently, cookware lids, handles, and other components are typically connected to the cookware body using rivets, which provides good connection strength and high processing efficiency. Cookware is frequently exposed to high temperature and humidity during use, and rivets, mostly made of metal, are prone to oxidation or corrosion in such environments. Therefore, rivets used in cookware generally require anti-corrosion coating. For cookware with non-stick coatings, the rivets also require a non-stick coating. Current rivet coating methods generally utilize coating jigs to place multiple rivets, allowing for simultaneous coating of multiple rivets. However, existing rivet coating jigs, after fixing the rivets, can easily obstruct the rivet heads, resulting in insufficient coating. Since the rivet heads are the exposed parts of the rivet, inadequate coating can easily lead to oxidation or corrosion, affecting the rivet's lifespan. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rivet spraying fixture that can fully spray the rivet heads of multiple rivets at one time, reducing defective products and improving spraying efficiency.

[0004] A rivet spraying fixture according to an embodiment of the present utility model includes:

[0005] The plate has multiple rivet holes, and a boss is provided at the top of the rivet holes. The boss is a ring structure with a high center and low perimeter, and the boss is arranged around the top of the rivet holes.

[0006] The disc body is attached to the lower side of the disc surface so that the bottom side of the rivet hole is higher than the bottom side of the disc body.

[0007] A rivet spraying fixture according to an embodiment of the present utility model has at least the following beneficial effects:

[0008] The rivet coating fixture has multiple rivet holes on its disc surface, allowing multiple rivets to be placed on the disc and coated simultaneously, improving production efficiency. An annular boss is located at the top of each rivet hole. The inner edge of the boss is higher than the outer edge, using the inner edge as a support point to support the inner part of the rivet head's bottom. This exposes the area near the outer periphery of the rivet head to air, creating an open gap between the area near the outer periphery and the outer edge of the boss for easy coating. This design prevents the entire bottom side of the rivet head from directly contacting the top of the rivet hole, thus avoiding obstruction of coating and ensuring the rivet head receives adequate coating, improving its corrosion resistance and anti-adhesion properties. A support body is located beneath the rivet coating fixture, providing support to the coating workbench or riveting machine. This ensures a gap between the bottom of the rivet coating fixture and the workbench or riveting machine when the fixture is placed in the rivet hole. This prevents the bottom of the rivet shank from directly contacting the workbench or riveting machine, thus avoiding loosening or detachment of the rivets and improving reliability. The fixture can apply a full coating to the rivet heads of multiple rivets at once, reducing defective products, decreasing the recoating rate, and improving coating efficiency.

[0009] According to an embodiment of the present invention, a rivet spraying fixture has a round rivet hole and a ring-shaped boss.

[0010] According to an embodiment of the present invention, a rivet spraying fixture is provided in which the rivet hole and the boss are concentrically arranged.

[0011] According to an embodiment of the present invention, a rivet spraying fixture has multiple rivet holes arranged neatly and at intervals on the disc surface.

[0012] According to an embodiment of the present invention, a rivet spraying fixture is provided on the disc surface with a plurality of positioning holes, which are located between adjacent rivet holes.

[0013] According to an embodiment of the present invention, a rivet spraying fixture has a disc body connected to the lower circumference of the disc surface, and the disc surface and the disc body form a receiving cavity.

[0014] According to an embodiment of the present utility model, a rivet spraying fixture has a first step portion on the disc body, which extends outward and downward at an angle.

[0015] According to an embodiment of the present utility model, a rivet spraying fixture is provided with a second step portion on the disc body. The second step portion is located below the first step portion and extends outward and downward at an angle. The projection of the second step portion along the height direction is located outside the projection of the first step portion along the height direction.

[0016] According to an embodiment of the present invention, a rivet spraying fixture has a flat edge protrusion on the bottom side of the disc body, which extends radially outward along the disc surface.

[0017] According to an embodiment of the present utility model, a rivet spraying fixture has multiple mounting holes on its body, which are evenly arranged around the circumference of the body.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figures 1 to 5 This utility model provides a rivet spraying fixture, including a disc surface 100 and a disc body 200. The disc surface 100 is provided with a plurality of rivet holes 110, and a boss 120 is provided at the top of the rivet holes 110. The boss 120 is an annular structure with a high center and low periphery, and the boss 120 is arranged around the top of the rivet holes 110. The rivet holes 110 can be round holes, polygonal holes, or other hole-shaped structures, and the boss 120 can be an annular structure, an elliptical annular structure, or a polygonal annular structure. Specifically, the rivet holes 110 are used to insert and place rivets 400, so that the head of the rivet 400 is facing upward and the tail is facing downward. The shank of the rivet 400 is located in the rivet hole 110, and the head of the rivet 400 is located above the boss 120, that is, the rivet head is located above the boss 120, which facilitates the spraying of coating on the rivet head. Specifically, refer to Figure 4The boss 120 is a ring structure with a high center and low periphery. That is, the height of the inner edge of the ring-shaped boss 120 is greater than the height of the outer edge. The inner edge of the ring-shaped boss 120 is used to support the inner part of the bottom side of the rivet head, that is, to support the part of the bottom side of the rivet head near the rivet shank, so that the part of the bottom side of the rivet head near the outer periphery is exposed. The disc body 200 is connected to the lower side of the disc surface 100 so that the bottom side of the rivet hole 110 is higher than the bottom side of the disc body 200. That is, in the height direction, the bottom side of the rivet hole 110 is above the bottom side of the disc body 200, so that when the rivet 400 is placed in the rivet hole 110, the bottom end of the rivet 400 does not directly contact the worktable or the riveting machine, thus preventing the rivet 400 from detaching from the rivet hole 110.

[0035] By providing multiple rivet holes 110 on the disc surface 100, multiple rivets 400 can be placed on the disc surface 100, allowing for simultaneous coating of multiple rivets 400 and improving production efficiency. The top of the rivet hole 110 is provided with an annular boss 120. The height of the inner edge of the boss 120 is greater than the height of the outer edge. The inner edge of the protruding boss 120 serves as a support point, supporting the inner part of the bottom side of the rivet head, thus exposing the bottom side of the rivet head near the outer periphery to the air. An open gap is formed between the bottom side of the rivet head near the outer periphery and the outer edge of the boss 120, facilitating coating. This prevents the entire bottom side of the rivet head from directly contacting the top of the rivet hole 110, thus avoiding obstruction of coating on the bottom side of the rivet head. This ensures the rivet head receives sufficient coating, improving its corrosion resistance and anti-adhesion properties. A disc body 200 is provided on the lower side of the disc surface 100. The disc body 200 supports the disc surface 100, ensuring a certain gap between the bottom side of the disc surface 100 and the spraying worktable or riveting machine when the rivet coating fixture is placed on the spraying worktable or installed on the riveting machine. This prevents the bottom end of the rivet 400 shaft from directly contacting the worktable or riveting machine when the rivet 400 is placed in the rivet hole 110, thus preventing the rivet 400 from loosening or even detaching and improving reliability. It can fully coat the rivet heads of multiple rivets 400 at once, reducing defective products, reducing re-coating rate, and improving spraying efficiency.

[0036] According to some embodiments of this application, refer to Figure 2 The rivet hole 110 is a round hole, and the boss 120 is a circular ring structure. The round rivet hole 110 makes it easier to insert the rivet 400, provides better positioning for the inserted rivet 400, and occupies less area on the disk surface 100. The circular boss 120 corresponds to the round rivet hole 110, reducing the area occupied on the disk surface 100, and allowing more rivet holes 110 and bosses 120 to be set within the limited area of ​​the disk surface 100.

[0037] Furthermore, the rivet hole 110 and the boss 120 are concentrically arranged to provide better support for the rivet 400, reduce the wobbling of the rivet 400, and further improve the utilization rate of the disc 100.

[0038] According to some embodiments of this application, refer to Figure 2 Multiple rivet holes 110 are neatly and evenly arranged on the disc surface 100. Specifically, the multiple rivet holes 110 are arranged in an array on the disc surface 100, with equal spacing between any two horizontally adjacent rivet holes 110 and equal spacing between any two vertically adjacent rivet holes 110. The neat and even arrangement of the rivet holes 110 on the disc surface 100 makes the installation of rivets 400 by the riveting machine easier and faster, thus improving the efficiency of rivet installation 400.

[0039] As a preferred embodiment, the spacing between two horizontally adjacent rivet holes 110 is equal to the spacing between two vertically adjacent rivet holes 110, which facilitates the use of the same dosage and angle for spraying in all spraying directions of the rivet 400, thereby improving the efficiency of coating spraying.

[0040] Furthermore, the disc surface 100 is also provided with a plurality of positioning holes 140, which are located between adjacent rivet holes 110. Specifically, there are two positioning holes 140, which are symmetrically arranged on the disc surface 100. The positioning holes 140 are used for positioning during the rivet 400 installation process to improve the accuracy of the riveting machine in the rivet 400 installation process, and at the same time improve the efficiency of rivet 400 installation.

[0041] According to some embodiments of this application, refer to Figure 1 and Figure 3 The disc body 200 is connected to the lower circumference of the disc surface 100, and the disc surface 100 and the disc body 200 together form a receiving cavity 300. Specifically, the disc body 200 is arranged around the lower circumference of the disc surface 100 to improve the structural strength of the disc body 200, reduce the possibility of deformation due to compression or impact, and also avoid affecting the rivet 400 inserted into the rivet hole 110. The receiving cavity 300 formed by the disc surface 100 and the disc body 200 can prevent the shank of the rivet 400 from being adhered to by the spraying liquid during the spraying process, keeping the shank of the rivet 400 clean, so that the rivet 400 can be more easily inserted and connected between various components in subsequent processes.

[0042] Furthermore, referring to Figure 1The disc body 200 is provided with a first step portion 210, which extends outward and downward at an angle. Specifically, the first step portion 210 is an inclined step structure, extending radially outward and downward along the disc surface 100. Specifically, the first step portion 210 is located at the top of the disc body 200, and its top end connects to the circumference of the disc surface 100, that is, the outer circumference of the disc surface 100 is connected to the first step portion 210. The first step 210 reduces the sharpness at the connection between the disc surface 100 and the disc body 200, lowering the risk of scratching other components or workers. The first step 210, which is inclined outward and downward, also facilitates the stacking and storage of rivet spraying fixtures. The bottom end of the disc body 200 of the upper rivet spraying fixture can be fitted onto the first step 210 of the lower rivet spraying fixture. The first step 210 serves to position and limit the movement of the upper rivet spraying fixture along the radial direction of the disc surface 100.

[0043] Furthermore, the disc body 200 is also provided with a second step portion 220, which is located below the first step portion 210. The second step portion 220 extends outward and downward at an angle, and its projection along the height direction is located outside the projection of the first step portion 210 along the height direction. Specifically, the second step portion 220 is also an inclined step structure, extending outward and downward at an angle along the disc surface 100. Specifically, refer to... Figure 5 The second step 220 is located in the middle of the disc body 200. The portion of the disc body 200 below the second step 220 and the portion of the disc body 200 between the first step 210 and the second step 220 are both vertically arranged. The second step 220 is positioned such that the projection of the portion of the disc body 200 between the first step 210 and the second step 220 along the height direction is inside the projection of the portion of the disc body 200 below the second step 220 along the height direction. When the rivet spraying jigs are stacked, refer to... Figure 5 The upper rivet spraying fixture disc 200 can be fitted onto the outside of the lower rivet spraying fixture disc 200 to better achieve the functions of positioning and limiting.

[0044] It is understood that, in some other embodiments, reference is made to... Figure 1 The bottom of the disc body 200 also has a third step 230, which is located below the second step 220. The third step 230 extends outward and downward at an angle, and its projection along the height direction is outside the projection of the second step 220 along the height direction. The third step 230 serves as a guide when the rivet spraying jigs are stacked and stored. (Refer to...) Figure 5The third step 230 of the upper rivet spraying fixture can be fitted onto the outside of the second step 220 of the lower rivet spraying fixture, further enhancing the positioning and limiting function, and also reducing the mutual wear between the upper and lower rivet spraying fixtures.

[0045] According to some embodiments of this application, refer to Figure 1 A flat-edge protrusion 240 is provided on the bottom side of the disc body 200, extending radially outward along the disc surface 100. Specifically, the flat-edge protrusion 240 is connected to the bottom end of the third step portion 230 and extends outward from the bottom end of the third step portion 230. By providing the flat-edge protrusion 240, the structural strength and stability of the disc body 200 are enhanced, preventing the disc body 200 from deforming due to high temperatures.

[0046] According to some embodiments of this application, refer to Figure 1 The disc body 200 is provided with multiple mounting holes 250, which are evenly arranged around the circumference of the disc surface 100. The mounting holes 250 facilitate the positioning and fixing of the rivet spraying fixtures when they are installed on the riveting machine, ensuring that the position and angle of each rivet spraying fixture are consistent after installation. This increases the success rate of the riveting machine in inserting the rivet 400 into the rivet hole 110, allowing for quick insertion and placement of the rivet 400.

[0047] It is understood that, in some other embodiments, reference is made to... Figure 4 The bottom end of the rivet hole 110 is provided with a relief portion 130, which extends obliquely downward and radially outward from the rivet hole 110. The relief portion 130 can increase the diameter of the bottom end of the rivet hole 110, making it easier and faster to insert the rivet 400 into the rivet hole 110, and also making it easier to remove the rivet 400 from the rivet hole 110 after spraying, further improving processing efficiency.
