Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to an external coating fixture. Background Technology

[0002] In existing coating processes, when spraying the surface, tooling is needed to position the product. The tooling used varies depending on the product. When applying the outer coating to products such as the inner pot of a rice cooker, a contour jig is needed to support the product from the inside in order to complete the spraying of the outer paint.

[0003] However, using contour jigs requires cleaning the jig surface and the inside of the product, which wastes manpower. Utility Model Content

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides an external coating tooling, which has the advantages of convenient cleaning and saving labor costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An external coating fixture is used to position and fix a cookware. The external coating fixture includes a fixing unit and a supporting unit. The supporting unit is detachably mounted on the fixing unit. The supporting unit includes an axial supporting part and an annular limiting part. The axial supporting part includes a supporting plane for supporting the end face of the open end of the cookware. The annular limiting part protrudes from the supporting plane and is used to surround the outside of the cookware to radially limit the cookware.

[0007] The support unit secures the cookware to be coated, using a ring-shaped limiting part for radial restraint and an axial support part for axial restraint, while also providing support for the cookware. The ring-shaped limiting part surrounds the cookware and provides radial restraint. By reducing the contact area between the fixture and the cookware to the open end of the cookware, the contact area is reduced, decreasing the area requiring cleaning and lowering cleaning costs.

[0008] Optionally, the height of the annular limiting portion protruding from the supporting plane is less than or equal to the height of the edge of the cookware along the axial direction.

[0009] The height of the annular limiting part needs to be such that it does not exceed the height of the edge of the cookware in the axial direction, so as to avoid the annular limiting part blocking the spraying of the cookware during spraying.

[0010] Optionally, the axial support portion is located on the periphery of the support unit, and the width of the axial support portion is greater than or equal to the width of the edge of the pot in the radial direction.

[0011] The axial support is used to support the cookware. The edge of the cookware is placed on the axial support. The width of the axial support needs to be greater than or equal to the width of the edge of the cookware in the radial direction so that the edge of the cookware does not exceed the axial support, thereby improving the stability of the placement.

[0012] Optionally, the support unit further includes a bearing portion, which is disposed on the side of the axial support portion away from the cookware, and the support unit is detachably connected to the fixing unit through the bearing portion.

[0013] The bearing portion is used to connect the support unit when the support unit and the fixed unit are supported and connected, and to provide support for the axial support portion and the annular limiting portion.

[0014] Optionally, a fixing hole is formed on the bearing portion, and the fixing unit includes a fixing member and a support tube. The fixing member is installed on the support tube and passes through the fixing hole to fix the support unit on the support tube.

[0015] The fixing hole is used to accommodate the fixing component when the support unit and the fixing unit are connected, so as to fix the position of the support unit by passing through the fixing hole and improve the fixing effect of the fixing component.

[0016] Optionally, the central region of the surface of the bearing portion near the support unit protrudes from the surface of the bearing portion surrounding the central region in the direction toward the support unit.

[0017] The center of the bearing part protrudes towards the support unit, allowing paint residue and other debris from the spraying process to accumulate at the center of the bearing part under gravity, making it easy to collect.

[0018] Optionally, the edge of the support tube is higher than the middle of the support tube, the bearing portion is attached to the edge of the support tube, and at least a portion of the bearing portion is lower than the edge of the support tube.

[0019] Part of the load-bearing structure extends into the support tube, and the top surface of the support tube fits against the load-bearing part. This improves the support effect of the support tube on the load-bearing part and achieves better stability.

[0020] Optionally, the fixing hole matches the fixing member, the shape of the fixing hole is the same as the cross-sectional shape of the fixing member, and it can restrict the circumferential rotation of the support unit along the axis of the fixing member.

[0021] The fixing hole is used to accommodate the fixing component, which is used to fix the support unit. The shape of the fixing hole and the cross-sectional shape of the fixing component are not circular, so that the support unit is snapped and fixed to the fixing component, preventing the support unit from rotating around the axis of the fixing component, thus improving the reliability of the tooling during use.

[0022] Optionally, the fixing hole is located in the center of the load-bearing part. When the fixing hole is located in the center of the load-bearing part, the applied load will be more evenly distributed throughout the entire load-bearing part, avoiding localized excessive stress and reducing stress concentration. This helps to improve the stability and strength of the entire structure.

[0023] Optionally, the support unit further includes a connector, a mounting hole is formed on the support tube, the bottom of the fixing member extends into the mounting hole and fixes the fixing member on the support tube, the connector is disposed at the bottom of the support tube and is coaxially fixed with the fixing member.

[0024] The connector is used to install the external coating fixture on the production line for assembly line operation, which can improve the work efficiency of spraying. Since the fastener and the connector are coaxially fixed, the external coating fixture has good stability during use, the force is even in all directions, and it is not easy for the center of gravity to shift or the fixture to tilt.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0032] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, element, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0033] In the current coating industry, when performing surface spraying, tooling is needed to position the product. The tooling used varies depending on the product. Traditional tooling for coating the inner pot of a rice cooker requires a contour jig to support the product from the inside in order to complete the spraying of the outer paint surface.

[0034] Profiling fixtures have a large contact surface with the product, requiring frequent cleaning of both the fixture surface and the product interior, thus wasting labor costs. Furthermore, the wide variety of products necessitates the use of numerous profiling fixtures of varying sizes, increasing processing costs and consuming storage space.

[0035] Based on this, such as Figure 1 As shown, one embodiment of this utility model discloses an external coating fixture for positioning and fixing a cookware. The external coating fixture includes a fixing unit 1 and a support unit 2, and the support unit 2 is detachably installed on the fixing unit 1.

[0036] In this embodiment, the product mentioned above is a cookware that needs to be sprayed. In other embodiments, it can also be other products that need to be sprayed.

[0037] The support unit 2 is detachably mounted on the fixed unit 1. For products of different sizes that need to be sprayed, the support unit 2 can be replaced to adapt to products of different sizes. The detachable installation reduces the difficulty of replacing the support unit 2, simplifies the replacement process, reduces the difficulty of operation, increases the time required to replace the support unit 2, and improves work efficiency.

[0038] Furthermore, in this embodiment, the support unit 2 is disc-shaped, which makes it easy to stack during storage, occupies little space, and reduces storage costs.

[0039] like Figure 1As shown, the support unit 2 includes an axial support portion 21 and an annular limiting portion 22. The axial support portion 21 includes a support plane 211, which is used to support the end face of the opening end of the cookware. The annular limiting portion 22 protrudes from the support plane 211 and is used to surround the outside of the cookware to radially limit the cookware.

[0040] When in use, the open end of the pot faces the support unit 2 and the pot is placed on the support plane 211. The open end of the pot is located inside the annular limiting part 22 and on the axial support part 21.

[0041] The axial support portion 21 is a ring structure used to support the open end of the pot. In this embodiment, the axial support portion 21 and the support plane 211 can be arranged in the horizontal direction. In other embodiments, the axial support portion 21 and the support plane 211 can also form an angle with the horizontal direction. This application does not specifically limit this.

[0042] The axial support 21 provides the best support in the horizontal direction, meaning that the product placed on it experiences zero resultant force in the horizontal direction and has no tendency to shift in the horizontal direction. This provides better fixation and prevents the product from shifting or falling off during the spraying process.

[0043] The annular limiting part 22 is an annular structure used to limit the outer wall of the open end of the pot. In this embodiment, the extension direction of the annular limiting part 22 is along the vertical direction. In other embodiments, the annular limiting part 22 may also form an angle with the vertical direction. This application does not specifically limit this.

[0044] The annular limiting part 22 achieves the best limiting effect when it is parallel to the vertical direction. That is, the product placed on it does not exert a direct force on the annular limiting part 22, reducing the contact area between it and the annular limiting part 22. It does not have a tendency to shift in the horizontal direction, has a better fixing effect, and can prevent it from shifting or falling off during the spraying process.

[0045] The support unit 2 secures the cookware to be coated. The axial support part 21 and the annular limiting part 22 axially limit the cookware and provide support. The annular limiting part 22 surrounds the cookware and radially limits its movement. By reducing the contact area between the fixture and the cookware to the open end of the cookware, the contact area is reduced, decreasing the area requiring cleaning and lowering cleaning costs.

[0046] like Figure 1 As shown, the height of the annular limiting part 22 protruding from the supporting plane 211 is less than or equal to the height of the edge of the pot along the axial direction.

[0047] The height of the annular limiting part 22 needs to be such that it does not exceed the height of the edge of the cookware in the axial direction, so as to avoid the annular limiting part 22 blocking the spraying of the cookware during spraying.

[0048] like Figure 1 As shown, the axial support portion 21 is located on the periphery of the support unit 2, and the width of the axial support portion 21 is greater than or equal to the width of the edge of the pot in the radial direction.

[0049] The axial support 21 is used to support the cookware. The edge of the cookware is placed on the axial support 21. The width of the axial support 21 needs to be greater than or equal to the width of the edge of the cookware in the radial direction so that the edge of the cookware does not exceed the axial support 21, thereby improving the stability of the placement.

[0050] like Figure 2 As shown, the support unit 2 also includes a bearing portion 23, which is disposed on the side of the axial support portion 21 away from the cookware. The support unit 2 is detachably connected to the fixing unit 1 through the bearing portion 23.

[0051] The bearing portion 23 is used to connect the support unit 2 when the support unit 2 is supported and connected to the fixing unit 1, and to provide support for the axial support portion 21 and the annular limiting portion 22.

[0052] like Figure 2 As shown, a fixing hole 231 is formed on the bearing part 23. The fixing unit 1 includes a fixing member 11 and a support tube 12. The fixing member 11 is installed on the support tube 12 and passes through the fixing hole 231 to fix the support unit 2 on the support tube 12.

[0053] The fixing hole 231 is used to accommodate the fixing member 11 passing through the fixing hole 231 to fix the position of the support unit 2 when the support unit 2 is supported and connected to the fixing unit 1, thereby improving the fixing effect of the fixing member 11.

[0054] like Figure 2 As shown, the central region of the surface of the bearing portion 23 near the support unit 2 protrudes from the surface of the bearing portion 23 surrounding the central region in the direction toward the support unit 2.

[0055] The central recessed structure of the bearing portion 23 can disperse externally applied pressure. This means that when external force or pressure is applied to the bearing portion 23, it can be effectively transmitted and dispersed through the shape of the bearing portion 23, reducing the risk of excessive local stress.

[0056] The center of the bearing part 23 protrudes towards the support unit 2, so that paint residue and other debris during the spraying process can be collected at the center of the bearing part 23 under the action of gravity, making it easy to collect.

[0057] like Figure 2 As shown, the edge of the support tube 12 is higher than the middle part of the support tube 12, the bearing part 23 is attached to the edge of the support tube 12, and at least part of the structure of the bearing part 23 is lower than the edge of the support tube 12.

[0058] In this embodiment, the bearing portion 23 is part of the surface of a cone, which can fit with the circular cross section at the top of the support tube 12. Furthermore, part of the structure of the bearing portion 23 extends into the support tube 12, so that the wide opening of the bearing portion 23 abuts against the inner wall of the support tube 12. This structure can effectively increase the stability of the entire system and prevent the bearing portion 23 from shifting or becoming unbalanced within the support tube 12.

[0059] Part of the structure of the bearing part 23 extends into the support tube 12, and the top surface of the support tube 12 is in contact with the bearing part 23. This can improve the support effect of the support tube 12 on the bearing part 23 and obtain better stability.

[0060] like Figure 2 As shown, the fixing hole 231 matches the fixing member 11. The shape of the fixing hole 231 is the same as the cross-sectional shape of the fixing member 11, and it can restrict the circumferential rotation of the support unit 2 along the axis of the fixing member 11.

[0061] In this embodiment, the shape of the fixing hole 231 and the cross-sectional shape of the fastener 11 are square, which are used to form a snap-fit ​​structure and to prevent the support unit 2 from rotating after installation. It should be noted that in practical applications, the shape of the fixing hole 231 and the cross-sectional shape of the fastener 11 are not limited to square. In other embodiments, the shape of the fixing hole 231 and the cross-sectional shape of the fastener 11 can also be other shapes, such as triangular, elliptical, hexagonal and other non-circular shapes. This application does not make specific requirements in this regard.

[0062] The fixing hole 231 is used to accommodate the fixing member 11, and the fixing member 11 is used to fix the support unit 2. The shape of the fixing hole 231 and the cross-sectional shape of the fixing member 11 are not circular, so that the support unit 2 is snapped and fixed to the fixing member 11, preventing the support unit 2 from rotating around the axis of the fixing member 11, thus improving the reliability of the tooling during use.

[0063] The fixing hole 231 is located in the middle of the bearing portion 23. When the fixing hole 231 is located in the center of the bearing portion 23, the applied load will be more evenly distributed throughout the entire bearing portion 23, avoiding localized excessive stress and reducing stress concentration. This helps to improve the stability and strength of the entire structure.

[0064] like Figure 2 and Figure 3As shown, the support unit 2 also includes a connector 24. The support tube 12 has a mounting hole 121. The bottom of the fixing member 11 extends into the mounting hole 121 and fixes the fixing member 11 to the support tube 12. The connector 24 is disposed at the bottom of the support tube 12 and is coaxially fixed with the fixing member 11.

[0065] The connector 24 is used to install the external coating fixture on the production line for assembly line operation, which can improve the work efficiency of spraying. Since the fastener 11 and the connector 24 are coaxially fixed, the external coating fixture has good stability during use, the force is even in all directions, and it is not easy for the center of gravity to shift or the fixture to tilt.

[0066] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and unit principles of this utility model will be included within the scope of the claims.
