[0021] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] The present application describes a valve core sleeve for automobile valve core processing, wherein the valve core sleeve 2 is used to sleeve the bottom of the valve core to form its vertical installation, wherein the valve core sleeve 2 includes a valve seat 21 for providing overall support, and a valve groove 22 provided on the valve seat 21 for sleeve-fitting the bottom of the valve core, the valve groove 22 extends from the inside of the valve seat 21 to the outside to form an open notch 23, and a positioning platform 24 and a guide platform 25 are respectively provided on both sides of the notch 23 for step-by-step buffering and docking the bottom of the valve core; it has the effect of facilitating and accurately positioning the valve core, and can use its step-by-step changing positioning notch to vertically position valve cores of different sizes.

[0023] In the embodiment of the present application, the valve core sleeve 2 is mainly used in the installer of the inner gasket in the automobile valve core, wherein the valve core sleeve 2 is installed on the base 1, and the valve core is positioned to thereby achieve fixation between the valve core and the gasket.

[0024] Among them, the valve core sleeve in automobile valve core processing is mainly used for positioning the valve core used in automobile processing.

[0025] The valve core sleeve 2 is used to sleeve the bottom of the valve core to form its vertical installation, perform vertical positioning, and help it perform vertical structural processing, such as: performing vertical processing of the valve core and the inner gasket.

[0026] The valve core sleeve 2 includes a valve seat 21 for providing overall support. The valve seat 21 is a rectangular parallelepiped structure with the characteristics of simple structure and stability.

[0027] The upper surface of the valve seat 21 is recessed downward to form a valve groove 22 for sleeve-fitting the bottom of the valve core, which has a cylindrical structure, a long strip structure, or a regular rectangular structure.

[0028] The valve groove 22 extends from the inside of the valve seat 21 to the outside to form an open notch 23, which facilitates the valve core to be inserted or plugged into the valve groove 22 along the open position of the notch 23 for positioning.

[0029] It extends outward along the middle position of the valve seat 21 to form an opening connected to the outside, which has the characteristics of easy positioning during processing and stable positioning.

[0030] A positioning platform 24 and a guide platform 25 for stepwise buffering of the bottom of the docking valve core are respectively provided on both sides of the notch 23. Steps and chute structures are respectively provided along the left and right sides to position and guide the valve core.

[0031] The notch 23 is used to connect with the bottom of the valve core. Two steps protruding into the valve slot 22 are respectively provided on the left and right sides of the notch 23. The step on the right is used to position the bottom of the valve core, namely the positioning platform 24, and the step on the left is used to guide the bottom of the valve core, namely the guide platform 25.

[0032] Among them, the positioning platform 24 is set on the right side, and the guide platform 25 is set on the left side. Guide and positioning structures are respectively set along the left and right sides. The positions of the structures can be interchanged, forming a step-by-step buffer installation and positioning effect of different lengths.

[0033] The overall length of the positioning platform 24 is greater than the overall length of the guide platform 25. In order to ensure the gradual buffering and positioning effect when the valve core is installed, Figure 2 As can be seen from the top view, the overall length of the positioning platform 24 is greater than the overall length of the guide platform 25, with a spacing d maintained therebetween. The spacing d can be positive or negative, ensuring that the valve core enters the valve slot 22 along the notch 23 for gradual positioning and step-by-step buffering.

[0034] The groove wall 221 of the valve groove 22 is extended outward to the right to form a positioning wall 241 on the right side of the positioning platform 24. In order to ensure stability during the positioning process of the right side, the valve core is slidably positioned by the positioning wall 241, which has a more stable installation feature.

[0035] A positioning step 242 is formed between the right side of the groove wall 221 and the right top end of the positioning wall 241. The valve core is positioned and buffered by the step on the right side.

[0036] The groove wall 221 along the valve groove 22 is expanded and extended to the left side to form a guide wall 251 on the left side of the guide platform 25. The valve core slides and guides along the left side, thereby realizing the sliding guidance of the valve core into the valve groove 22.

[0037] A guide step 252 is formed between the left side of the groove wall 221 and the left top end of the guide wall 251 .

[0038] The valve core is installed in a guided and buffered manner by the step on the left side.

[0039] The valve seat 21 is a rectangular parallelepiped structure, and each of its butt ends is provided with a fixing hole 26. To ensure symmetrical installation and force balance of the valve seat 21, bolts are installed through the fixing holes on the diagonal corners of the valve seat 21 to achieve a stable, symmetrical and balanced installation effect.

[0040] The valve core is a valve body with a cylindrical structure. A circular sealing ring is set along the hollow center of the valve core for positioning and installation. The gasket is pressed and positioned from top to bottom by the gasket pressure head 3, overcoming the low efficiency of manual installation and the inconvenience of extrusion and shaping installation in the existing technology. The base 1 is used for unified positioning to overcome the situation of inaccurate positioning.

[0041] See also Figure 1 As shown in , the valve core sleeve 2 is mainly used in the installer of the inner gasket in the automobile valve core, wherein the valve core sleeve 2 is installed on the base 1, and the valve core and the gasket are fixed by positioning the valve core.

[0042] A device for installing an inner gasket in an automobile valve core comprises a base 1 for positioning and installing the automobile valve core. The base 1 is provided with a gasket pressing head 3 for squeezing the gasket in the automobile valve core. The valve core and gasket in the valve core sleeve 2 are extruded from top to bottom by the gasket pressing head 3.

[0043] Wherein, a valve core sleeve 2 for positioning the automobile valve core is provided on the base 1. The valve core sleeve 2 is mainly used for vertically positioning the valve core to facilitate the valve core opening upward.

[0044] The gasket pressing head 3 is arranged along the upper part of the valve core sleeve 2, so as to facilitate pressing the gasket into the valve core from top to bottom.

[0045] A booster 4 is provided on the upper portion of the gasket pressure head 3 to assist it in performing the extrusion movement. The valve core and the gasket are pressed into an integrated structure by means of boosting, thereby achieving a precise combination between the two.

[0046] The booster 4 is configured as a fixedly mounted cylinder, wherein the booster 4 is a cylinder that can be set to a fixed air pressure value, thereby limiting the engagement pressure between the compression valve core and the gasket to a fixed value, achieving the effects of efficient positioning and precise pressure positioning.

[0047] A booster shaft 41 is provided between the booster 4 and the gasket head 3 to drive the gasket head 3 to move. The pressure is transmitted to the cylinder by shaft transmission, and then to the space between the valve core and the gasket through the shaft.

[0048] In another embodiment of the present application,

[0049] The boost shaft 41 is fixed along the upper part of the gasket pressure head 3, and is fixed along the upper part to ensure positioning from top to bottom, which is conducive to positioning the gasket and the valve core from top to bottom.

[0050] A positioning sleeve 42 and a positioning plate 45 are provided at the bottom of the boost shaft 41 to help position the wire.

[0051] In order to ensure the positioning accuracy of the boost shaft 41 during movement, the position of the boost shaft 41 is limited by the positioning sleeve 42. To further limit the position of the boost shaft 41, the positioning sleeve 42 is installed using the positioning plate 45, thereby ensuring its accurate positioning and correction as a whole.

[0052] For example, the positioning sleeve 42 is arranged along the middle position of the positioning plate 45. Arranging it along the middle position is beneficial to the realization of various structures in the manufacturing process.

[0053] The positioning plate 45 is a rectangular plate with a regular structure that further ensures installation. Four vertical positioning shafts 43 are provided at the four ends of the positioning plate 45. To ensure the vertical positioning accuracy of the supercharger shaft 41, the positioning shafts 43 support the positioning plate 45, forming a stable vertical support. The vertical support ensures the spacing position is achieved.

[0054] In another embodiment of the present application,

[0055] The upper portion of the positioning plate 45 is provided with a fixing seat 44 for mounting the supercharger 4. The fixing seat 44 is provided along the top of the four positioning shafts 43, and the supercharger shaft 41 is fixedly mounted through the middle of the fixing seat 44. The supercharger 4 is inserted downward into the fixing seat 44 for positioning, thereby ensuring that the supercharger 4 extends downward and stably from the positioning shaft 43.

[0056] In the embodiment of this application,

[0057] The base 1 is provided with a correction plate 11 for installing the valve core sleeve 2. In order to further ensure that the installation position of the valve core can be accurately achieved, the position of the valve core sleeve 2 is installed by the correction plate 11, and the valve core sleeve 2 is adjustable after installation, which has the effect of correcting the position of the valve core sleeve 2.

[0058] The correction plate 11 is installed along the surface of the base 1 and is plugged into the base 1 through the limiting shaft 12 to achieve fixed connection between the correction plate 11 and the base.

[0059] The correction plate 11 extends upward with a limiting shaft 12 for protecting the extrusion height of the valve core sleeve 2. During the installation of the correction plate 11, the limiting shaft 12 is inserted into the correction plate 11, which not only positions the correction plate 11, but also separates the limiting shaft 12 on both sides of the valve core sleeve 2, protecting and blocking the outside of the valve core sleeve 2, and protecting the valve core sleeve 2 from being affected by the external operating structure after positioning.

[0060] The foregoing is merely an embodiment of the present application. Furthermore, the names of the components in this application may be different and do not limit the names in this application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the concepts and principles of this application are intended to be included within the scope of the claims of this application.
