Description

Technical Field

[0001] The present application relates to the technical field of plastic valve core processing, and in particular to an auxiliary gluing jig for processing plastic valve cores. Background Art

[0002] At present, plastic valve cores have gradually replaced traditional metal valve cores in many industries due to their advantages of low cost, light weight and corrosion resistance, especially in the fields of industrial valves and plumbing equipment. Their wide application not only improves production efficiency, but also reduces manufacturing costs, making products more competitive in the market.

[0003] like Figure 1 As shown, there is an existing plastic valve core, which includes a bottom plate 6 and a cylindrical shell 7 integrally formed on the bottom plate 6. A water groove 71 is radially penetrated through the side wall of the shell 7 away from the bottom plate 6. A mounting groove 72 for mounting a rubber sealing ring 9 is provided on the side wall of the shell 7. Four abutment blocks 8 are also fixed on the bottom plate 6. The four abutment blocks 8 are evenly distributed along the circumference of the shell 7. Square holes 81 are provided on two of the oppositely arranged abutment blocks 8. An annular groove 73 is also provided on the outer wall of the shell 7. The groove 73 is located between the installation groove 72 and the abutment block 8; when in use, a rubber sealing ring 9 needs to be formed in the installation groove 72 through a vulcanization process, so that in the subsequent use process, the sealing ring 9 can ensure the sealing effect of the valve core blocking the pipeline. In addition, since the bonding strength between the rubber sealing ring 9 and the plastic valve core is relatively poor, it is usually necessary to apply a circle of glue on the bottom side of the installation groove 72 before molding the rubber sealing ring 9, so as to ensure the stability of the bonding between the sealing ring 9 and the plastic valve core after molding the rubber sealing ring 9.

[0004] In the process of applying glue to the installation groove 72 on the above-mentioned plastic valve core, in the prior art, the staff mainly manually applies the glue evenly to the installation groove 72 on the outer wall of the plastic valve core. However, in actual operation, since the outer wall of the plastic valve core is usually relatively smooth and has a curved shape, it is easy for the glue to be unevenly applied or exceed the designated area during the gluing process, thereby causing part of the glue to be wasted and increasing the difficulty of subsequent processing. Utility Model Content

[0005] In order to improve the convenience for workers to apply glue on the outer wall of the plastic valve core, the present application provides an auxiliary glue coating jig for processing the plastic valve core.

[0006] This application provides an auxiliary gluing jig for processing plastic valve cores, which adopts the following technical solutions:

[0007] An auxiliary gluing jig for processing plastic valve cores includes a jig body, a groove for embedding a shell is provided on the jig body, a gluing port is provided on the outside of the jig body, the gluing port is connected to the groove, and a positioning structure is provided on the jig body, the positioning structure is used to align the mounting groove on the shell with the gluing port.

[0008] By adopting the above technical solution, when in use, the valve core is inserted into the embedded groove, and the valve core is positioned by the positioning structure so that the installation groove on the valve core is aligned with the glue application port. The subsequent staff can apply glue to the inner wall of the installation groove through the glue application port. During the gluing process, the glue outlet of the glue injection gun is limited by the side wall of the glue application port, thereby limiting the staff's glue application area, thereby reducing the situation of applying glue outside the designated area when applying glue. Compared with the method of applying glue directly in the installation groove, it is simpler and more convenient.

[0009] Preferably, the fixture body includes a base and a positioning cylinder fixed on the base, a receiving groove is provided on the side of the base facing away from the positioning cylinder, the embedding groove is provided on the bottom wall of the receiving groove, and the embedding groove connects the receiving groove with the positioning cylinder, the glue application port is located on the side wall of the positioning cylinder, and the glue application port is provided radially through the positioning cylinder, and the positioning structure is provided on the inner wall of the positioning cylinder.

[0010] By adopting the above technical solution, when in use, the valve core shell is inserted into the positioning tube after passing through the embedding groove, and glue is applied to the installation groove through the glue application port on the positioning tube. The overall use is simple and convenient.

[0011] Preferably, the positioning structure includes a positioning protrusion fixed to the inner wall of the positioning cylinder, and the positioning protrusion is plugged into and matched with the water groove on the shell.

[0012] By adopting the above technical solution, when in use, after the shell is inserted into the positioning cylinder, the positioning protrusion can be embedded in the water groove to achieve the fixing of the shell angle, thereby ensuring that the mounting groove on the shell is aligned with the glue application port, thereby facilitating the subsequent glue application by the staff.

[0013] Preferably, the positioning protrusion is formed with an arc surface on one end facing the base.

[0014] By adopting the above technical solution, when in use, the insertion angle of the shell is guided by the arc surface, so as to facilitate the angle positioning of the shell after being inserted into the embedding groove, which is more convenient to use.

[0015] Preferably, after the shell is inserted into the positioning cylinder and the mounting groove is aligned with the glue application port, the abutment block is in abutment fit with the bottom wall of the receiving groove.

[0016] By adopting the above technical solution, when in use, the purpose of axially positioning the shell in the positioning cylinder is achieved through the cooperation between the bottom wall of the receiving groove and the abutment block, further ensuring the accuracy of subsequent glue coating in the installation groove.

[0017] Preferably, a plurality of embedding grooves are provided, and the plurality of embedding grooves are evenly spaced along the length direction of the base, and an anti-slip structure for preventing the housing valve core from escaping from the embedding groove is provided at the notch of each embedding groove.

[0018] By adopting the above technical solution, when in use, several embedding grooves are opened to facilitate the staff to apply glue to the installation grooves on multiple valve cores at one time, thereby increasing the processing efficiency of the valve core. At the same time, the valve core is fixed by the anti-slip structure to reduce the possibility of the valve core detaching from the embedding groove during glue application.

[0019] Preferably, the anti-slip structure includes a snap-fitting convex ring fixed on the inner wall of the notch of the embedding groove. After the shell is inserted into the positioning cylinder, the snap-fitting convex ring is embedded and matched with the ring groove.

[0020] By adopting the above technical solution, when in use, the snap-fitting convex ring is integrally formed on the inner wall of the embedding groove, and the entire fixture body is made of soft rubber material. When the shell is inserted into the positioning cylinder, the staff only needs to bend the side wall of the embedding groove to embed the snap-fitting convex ring into the ring groove, thereby realizing the snap-fitting limit of the shell, and the overall use is simple and convenient.

[0021] Preferably, the anti-slip structure includes an insert block fixed on the inner side wall of the receiving groove, and after the shell is inserted into the positioning cylinder, the insert block is plugged into and matched with the square hole on the abutment block.

[0022] By adopting the above technical solution, when in use, by utilizing the existing square hole structure on the abutment block, an insert block that matches the square hole is set on the inner wall of the storage groove, which can further improve the stability of the shell installed in the embedding groove, thereby ensuring the stability of the subsequent gluing process.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By inserting the valve core into the embedded groove and applying glue to the installation groove on the valve core through the glue application port, the glue injection gun can be limited by the side wall of the glue application port, thereby ensuring the accuracy of the glue application process and improving the convenience of the glue application process;

[0025] 2. When in use, the angle of the shell inserted into the embedding groove is positioned by the positioning protrusion, and the axial position of the shell is positioned by the abutment block against the bottom wall of the receiving groove, so as to ensure that the installation groove on the shell is aligned with the glue application port, thereby ensuring the accuracy of the subsequent glue application process;

[0026] 3. By opening several embedding grooves, glue can be applied to the inner walls of multiple valve cores at one time, which improves the gluing efficiency. At the same time, with the help of the anti-slip structure, the possibility of the valve core detaching from the fixture body during the gluing process is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is combined with Figure 2 -Attached Figure 6 This application is described in further detail.

[0035] The embodiment of the present application discloses an auxiliary gluing jig for processing a plastic valve core.

[0036] Reference Figure 2 and Figure 3, an auxiliary gluing jig for processing plastic valve cores, including a horizontally placed jig body 1. In this embodiment, the jig body 1 is made of soft rubber material as a whole. The jig body 1 is divided into two parts: a base 11 and a positioning cylinder 12. The base 11 and the positioning cylinder 12 are integrally formed. The base 11 is in the shape of a rectangular block as a whole, and the positioning cylinder 12 is in the shape of a cylinder as a whole. The open end of the positioning cylinder 12 is connected to the base 11, and in this embodiment, the inner cavity shape of the positioning cylinder 12 is matched with the shape of the valve core shell 7. A receiving groove 13 is provided on the bottom surface of the base 11, and an embedded groove 2 is provided at the bottom of the receiving groove 13. The embedded groove 2 connects the receiving groove 13 and the positioning cylinder 12.

[0037] Reference Figure 2 and Figure 3 In order to increase the number of valve cores that can be processed at one time, several embedding grooves 2 are provided in the present application, and the several embedding grooves 2 are evenly spaced along the length direction of the base 11. In this embodiment, four embedding grooves 2 are preferably provided, and a gluing port 3 is provided on the side wall of the positioning cylinder 12. The opening direction of the gluing port 3 is along the radial direction of the positioning cylinder 12. The gluing port 3 is connected to the inside of the positioning cylinder 12, and a positioning structure 4 is also provided in the positioning cylinder 12. When in use, the housing 7 of the valve core is inserted into the positioning cylinder 12 along the embedding groove 2, and the mounting groove 72 on the housing 7 is aligned with the gluing port 3 through the positioning structure 4. After that, the gluing range can be limited by the inner wall of the gluing port 3, so as to avoid exceeding the specified gluing range during gluing.

[0038] Reference Figure 3 and Figure 4 The positioning structure 4 is composed of two positioning protrusions 41. The two positioning protrusions 41 are integrally formed on the inner wall of the positioning tube 12, and the two positioning protrusions 41 are arranged opposite to each other. When the shell 7 is inserted into the positioning tube 12, the positioning protrusion 41 can be inserted into the water groove 71 on the shell 7, thereby realizing the angle positioning of the shell 7 through the cooperation between the positioning protrusion 41 and the water groove 71; in addition, in order to facilitate the positioning protrusion 41 to be embedded in the water groove 71, a circular arc surface 42 is formed at one end of the positioning protrusion 41 facing the base 11, so that when in use, the shell 7 is guided to be inserted into the positioning tube 12 by the circular arc surface 42, and the positioning protrusion 41 is gradually embedded in the water groove 71.

[0039] Reference Figure 3 and Figure 4 In order to achieve axial positioning of the shell 7, when the shell 7 is inserted into the positioning cylinder 12 and the mounting groove 72 is aligned with the glue application port 3, the end of the abutment block 8 abuts against the bottom wall of the receiving groove 13, thereby cooperating with the setting of the positioning protrusion 41 to ensure that the glue application port 3 is aligned with the mounting groove 72; at the same time, when the valve cores are inserted into the four embedded grooves 2 on the base 11, in order to ensure that the valve core does not separate from the base 11 during the glue application process, an anti-slip structure 5 is provided at the notch of each embedded groove 2 on the base 11.

[0040] Reference Figure 3 and Figure 4 The anti-slip structure 5 is composed of two clamping convex rings 51. The two clamping convex rings 51 are integrally formed on the inner wall of the notch of the embedding groove 2, and the two clamping convex rings 51 are arranged opposite to each other. When the shell 7 is inserted into the positioning cylinder 12 and the end of the abutting block 8 abuts against the bottom wall of the receiving groove 13, the clamping convex ring 51 is embedded in the annular groove 73 on the shell 7, thereby realizing the clamping and positioning of the valve core through the clamping cooperation between the annular groove 73 and the clamping convex ring 51, thereby reducing the possibility of the valve core escaping from the embedding groove 2 during the gluing process; when in use, the staff can bend the base 11 to deform the base 11, thereby driving the clamping convex ring 51 to deform, until the clamping convex ring 51 is embedded in the annular groove 73, and the base 11 can be loosened, thereby realizing the clamping and fixing of the valve core.

[0041] When the valve core is fully embedded in the embedding groove 2, the base 11 can be loosened. Under the elastic deformation of the base 11 itself, the base 11 returns to its original shape and drives the clamping convex ring 51 to embed in the annular groove 73. At this time, under the cooperation of the positioning protrusion 41 and the abutment block 8, the installation groove 72 on the valve core is aligned with the glue application port 3. Finally, the staff can inject glue into the installation groove 72 through the glue application port 3. During the glue injection process, the glue gun is limited by the side wall of the glue application port 3 to prevent glue from being applied to the area outside the installation groove 72 during glue injection. At the same time, four valve cores are installed on one base 11 at a time, which can increase the efficiency of glue application and make it more convenient to use.

[0042] The difference between Example 2 and Example 1 is that:

[0043] Reference Figure 5 and Figure 6 In this embodiment, the anti-slip structure 5 can also be composed of an insert block 52. Two insert blocks 52 can be provided, and the two insert blocks 52 are arranged on both sides of the embedding groove 2 opposite to each other. The insert blocks 52 are integrally formed on the inner wall of the storage groove 13. When the shell 7 is inserted into the positioning cylinder 12, the staff will bend the base 11 to deform the base 11, thereby driving the insert block 52 away from the shell 7, and then continue to move the shell 7 into the positioning cylinder 12. When the square hole 81 on the abutment block 8 is aligned with the insert block 52, the base 11 can be released. After that, the base 11 returns to its original shape under the action of its own elastic deformation, thereby driving the insert block 52 to be inserted into the square hole 81, thereby realizing the clamping and fixing of the valve core. The overall use is simple and convenient.

[0044] Reference Figure 5 and Figure 6At the same time, the plug block 52 in this embodiment can also be used in conjunction with the clamping protrusion 51 in Example 1 to further increase the clamping stability of the valve core, thereby further reducing the possibility of the valve core detaching from the base 11 during the gluing process, thereby ensuring the gluing quality.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
