Description

Technical Field

[0001] The utility model relates to the technical field of coil processing, in particular to an integrated tool for assembling and baking a coil of a valve body with a metal shell. Background Art

[0002] Coil assembly with metal shell valve body refers to installing a cylindrical coil in a cylindrical metal shell on the valve body. To ensure the firmness of the assembly, a layer of glue is usually applied to the surface of the coil so that the coil can be quickly adhered to the metal shell after drying to form a finished product.

[0003] However, after the assembled metal shell and coil are heated and baked, the stress generated during the glue curing process will cause the dimensions of the two to become unstable, affecting the concentricity of the two, and causing the finished product to be out of center. As a result, the size of the finished product cannot meet customer requirements, and the company's production costs increase.

[0004] Therefore, the present application provides an integrated tooling for assembling and baking a coil with a metal shell valve body to solve the above problems. Utility Model Content

[0005] In order to overcome the above shortcomings, the purpose of the utility model is to provide an integrated tooling for assembling and baking the coil with a metal shell valve body, which has a simple structure and is easy to disassemble, ensures the concentricity of the metal shell and the coil after assembly and baking, improves the yield of the assembled product, and reduces the production cost of the enterprise.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: an integrated tool for assembling and baking a metal shell valve body coil, including a tool base, a concentric ring and a locking assembly; the concentric ring is sleeved on the bottom of the tool base, and a finished product accommodating cavity is formed between the inner ring of the concentric ring and the tool base for inserting the finished product after gluing, and the locking assembly includes a pressure ring, which can press the finished product tightly on the tool base and is detachably connected to the top of the tool base.

[0007] Furthermore, the tooling base includes a plug-in portion and a sleeve portion. The plug-in portion is convex-shaped, and the sleeve portion is a vertically arranged columnar structure. The plug-in portion and the sleeve portion are integrally formed. The columnar structure of the sleeve portion matches the size of the hollow structure of the coil, allowing the coil to be sleeved on the sleeve portion, with its bottom portion inserted downwardly into the finished product receiving cavity, achieving preliminary positioning of the assembly on the tooling.

[0008] Furthermore, the concentric ring is sleeved on the plug-in portion, and the upper surface of the concentric ring is higher than the upper surface of the plug-in portion, so that the finished product accommodating cavity is formed between at least a portion of the inner ring of the concentric ring, the upper surface of the plug-in portion, and the outer ring of the sleeve portion.

[0009] Furthermore, the upper surface of the plug-in portion is provided with an annular sealing ring receiving groove for accommodating a bottom sealing ring. After the assembly is inserted into the finished product receiving cavity, its bottom abuts against the bottom sealing ring. Since the metal shell and the coil are bonded together by glue, glue overflow may occur at the bottom of the assembly when placed vertically. The provision of the bottom sealing ring effectively prevents glue from directly overflowing onto the tooling base, facilitating disassembly of the assembly and tooling. Furthermore, the bottom sealing ring can be replaced and cleaned in real time, making replacement of the bottom sealing ring easier and less costly than replacing the entire tooling base.

[0010] Furthermore, the pressure ring is locked to the top of the tooling base via a locking screw. The sleeve portion has a locking threaded hole along its height that matches the locking screw. After the assembly is inserted into the tooling base, the stud end of the locking screw passes through the central hole of the pressure ring and into the locking threaded hole. Turning the nut end of the locking screw presses the pressure ring against the upper surface of the assembly, effectively preventing relative positional movement between the metal housing and the coil during the baking process, thereby ensuring consistent concentricity between the two.

[0011] Furthermore, the locking assembly includes a locking cover with a clearance hole for the locking screw to pass through. The portion of the locking screw located between the locking cover and the pressure ring is sheathed with a buffer spring. When the assembly is tightened, the locking cover is positioned between the nut end of the locking screw and the pressure ring. Furthermore, a buffer spring is provided between the locking cover and the pressure ring. This effectively prevents the coil and metal housing from being damaged by excessive tightening force when the locking screw is tightened, thus preventing deformation of the coil and metal housing that could affect production efficiency.

[0012] Furthermore, a plurality of limiting claws are provided on the side of the lock cover facing the tooling base along its edge, and a limited space is formed between the plurality of limiting claws and the lock cover for the pressure ring to be placed in and guided.

[0013] Furthermore, the inner side surface of the limiting claw is an arc-shaped surface that matches the outer arc surface of the pressure ring. While limiting the pressure ring, it can also ensure that the surface of the pressure ring will not be damaged.

[0014] Beneficial effects of the utility model:

[0015] In the utility model, the tooling base, the concentric ring and the locking assembly cooperate with each other, and a limited space is formed between the concentric ring and the tooling base for inserting the assembly of the coil and the metal shell to perform preliminary positioning of the assembly. The pressure ring is detachably connected to the tooling base, and the pressure ring can press the assembly tightly on the tooling base. The structure of the entire tooling is simple and easy to disassemble, which can effectively ensure the concentricity of the metal shell and the coil after assembly and baking, improve the yield of the assembled finished product, and reduce the production cost of the enterprise.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] Both the coil and the metal casing are hollow structures, extending from top to bottom. The coil is coated with glue and then inserted into the metal casing, completing the final assembly. To expedite the finalization of the coil and metal casing, the assembly is baked in an oven. However, high temperatures can cause stress when the glue cures, leading to relative positional shift between the coil and metal casing. This can manifest as upward and downward movement. Furthermore, component misalignment can occur, leading to concentricity deviations between the metal casing and the coil.

[0022] Therefore, see Appendix Figures 1 to 3 The present application provides an integrated tool for assembling and baking a coil with a metal shell valve body to solve the above-mentioned problems, comprising a tool base 1, a concentric ring 4, and a locking assembly 6; the concentric ring 4 is sleeved on the bottom of the tool base 1, and a finished product accommodating cavity 5 is formed between the inner ring of the concentric ring 4 and the tool base 1 for inserting the finished product after gluing. When in use, in the assembly to be baked, the hollow structure on the coil is sleeved on the tool base 1, and the bottom of the entire assembly is inserted into the finished product accommodating cavity 5, and the bottom of the assembly is preliminarily positioned by the finished product accommodating cavity 5;

[0023] The locking assembly 6 includes a pressure ring 63, which can press the finished product onto the tooling base 1 and is detachably connected to the top of the tooling base 1. After the assembly is inserted into the finished product receiving cavity 5, the pressure ring 63 is fixed to the top of the tooling base 1. The assembly is now confined between the tooling base 1 and the pressure ring 63, and the pressure ring 63 firmly presses the assembly onto the tooling base 1. During the baking process, even if the glue cures and generates stress, the coil and the metal shell cannot rotate or float relative to each other.

[0024] The tooling is simple and easy to disassemble as a whole, which can not only ensure the concentricity of the metal shell and the coil after assembly and baking, but also improve the yield rate of the assembled product, thereby reducing the company's production costs.

[0025] The tooling base 1 comprises a plug-in portion 11 and a sleeve portion 12. The plug-in portion 11 is convex-shaped, while the sleeve portion 12 is a vertical columnar structure. The plug-in portion 11 and the sleeve portion 12 are integrally formed. The columnar structure of the sleeve portion 12 matches the size of the hollow structure of the coil, allowing the coil to be sleeved onto the sleeve portion 12, with its bottom portion inserted downwardly into the finished product receiving cavity 5, achieving initial positioning of the assembly on the tooling.

[0026] The concentric ring 4 is sleeved over the inserting portion 11, with the upper surface of the concentric ring 4 being higher than the upper surface of the inserting portion 11. This forms the finished product receiving cavity 5 between at least a portion of the inner ring of the concentric ring 4, the upper surface of the inserting portion 11, and the outer ring of the sleeve portion 12. This ensures that the bottom of the assembly can be positioned and limited in position after being inserted into the finished product receiving cavity 5.

[0027] Specifically, the convex plug-in part 11 includes a lower cone and an upper cone. When socketed, the lower surface of the concentric ring 4 abuts against the upper surface of the lower cone of the plug-in part 11, and its inner ring contacts the outer periphery of the upper cone. The part of the concentric ring 4 that is not in contact with the outer periphery of the upper cone forms a space with the upper surface of the upper cone and the outer periphery of the socket part 12 that is just enough for the glued product to be inserted, which is the finished product accommodating cavity 5.

[0028] The upper surface of the plug-in portion 11 is provided with an annular sealing ring receiving groove for accommodating the bottom sealing ring 2. After the assembly is inserted into the finished product receiving cavity 5, its bottom abuts against the bottom sealing ring 2. Since the metal shell and the coil are adhered by glue, glue overflow may occur at the bottom of the assembly when placed vertically. The provision of the bottom sealing ring 2 effectively prevents glue from directly overflowing onto the tooling base 1, facilitating the disassembly of the assembly and the tooling. At the same time, the bottom sealing ring 2 can be replaced and cleaned in real time. Compared with replacing the entire tooling base 1, replacing the bottom sealing ring 2 is easier to operate and less expensive.

[0029] The pressure ring 63 is locked to the top of the tooling base 1 via a locking screw 62. The sleeve portion 12 is provided with a locking threaded hole 3 along its height that matches the locking screw 62. After the assembly is inserted into the tooling base 1, the stud end of the locking screw 62 passes through the central jackhole of the pressure ring 63 and is inserted into the locking threaded hole 3. By turning the nut end of the locking screw 62, the pressure ring 63 is pressed against the upper surface of the assembly, effectively preventing relative positional movement between the metal housing and the coil during the baking process, thereby ensuring consistent concentricity between the two.

[0030] Furthermore, the locking of the locking screw 62 can facilitate the staff to quickly disassemble and assemble the tooling and assembly parts, making it more convenient to use.

[0031] The locking assembly 6 also includes a locking cover 61, which has a clearance hole for a locking screw 62 to pass through. A buffer spring 64 is sleeved around the portion of the locking screw 62 between the locking cover 61 and the pressure ring 63. When the assembly is tightened, the locking cover 61 is cushioned between the nut end of the locking screw 62 and the pressure ring 63. Furthermore, a buffer spring 64 is provided between the locking cover 61 and the pressure ring 63. This effectively prevents the coil and metal housing from being damaged by excessive tightening force when the locking screw 62 is tightened, thus preventing deformation of the coil and metal housing that could affect production efficiency.

[0032] A plurality of limiting claws 611 are provided along the edge of the locking cover 61 on the side facing the tooling base 1. A confined space is formed between the limiting claws 611 and the locking cover 61 for the pressure ring 63 to be placed and guided. The confined space formed by the limiting claws 611 effectively guides the movement of the pressure ring 63. Under the action of the locking screw 62 and the buffer spring 64, the pressure ring 63 moves along the confined space until it contacts the upper surface of the assembly and presses it against the tooling base 1. The provision of the limiting claws 611 also limits the pressure ring 63, preventing it from shifting in position during the process of pressing the assembly, which could result in uneven force on the top of the assembly and affect the baking and positioning of the assembly.

[0033] The inner side surface 612 of the limiting claw 611 is an arc surface that matches the outer arc surface 631 on the pressure ring 63. While limiting the pressure ring 63, it can also ensure that the surface of the pressure ring 63 will not be damaged.

[0034] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
