Description

Technical Field

[0001] The utility model mainly relates to the technical field of positioning tooling, in particular to a positioning tooling for riveting a wax package component. Background Art

[0002] In production, the wax package assembly closing station needs to connect the valve disc and the wax package rod body together through a riveting process. The valve disc and the wax package rod body are completely automatically loaded by the equipment. The existing riveting tooling is as follows Figure 1 As shown, the positioning tooling includes a mounting seat, a main ring body and a supporting convex ring. The mounting seat is located at the lower end of the main ring body, and the supporting convex ring is located at the top of the main ring body. A through hole adapted to the wax-coated rod body is formed on the central axis of the positioning tooling. When used, the automatic feeding equipment inserts the wax-coated rod body into the through hole from the top of the positioning tooling. The protruding part of the wax-coated rod body is located on the inner side of the supporting convex ring and partially exposed. Then, the valve disc is mounted on the exposed part of the protruding part of the wax-coated rod body through the automatic feeding equipment, and finally, riveting is performed to connect the wax-coated rod body and the valve disc together. However, due to the small specifications of some wax-coated valve discs and the small contact area with the tooling, the automatic feeding of the valve disc is frequently not in place, which ultimately leads to a low qualified rate of the wax-coated assembly after riveting (about 98%). In order to improve the qualified rate, the tooling needs to be optimized. Utility Model Content

[0003] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. It mainly provides a positioning tool for riveting processing of wax package components to solve the technical problem that the valve disc is frequently not in place when automatically feeding it mentioned in the above background technology.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A positioning tool for a wax package assembly subjected to riveting treatment comprises a main ring body with a mounting seat, wherein a supporting convex ring is formed on the end face of the main ring body facing away from the mounting seat; a retaining ring body connected to the end face of the main ring body is coaxially arranged on the outer side of the supporting convex ring.

[0006] Furthermore, a sloped annular surface is provided on the inner ring side of the enclosure ring body, and the diameter of the sloped annular surface at one end away from the main ring body is larger than the diameter of the sloped annular surface at one end close to the main ring body.

[0007] Furthermore, the end surface of the supporting protruding ring away from the main ring body is flush with the end surface of the enclosing ring body away from the main ring body, and the end of the sloped ring surface away from the main ring body is flush with the end surface of the enclosing ring body away from the main ring body.

[0008] Furthermore, the outer diameter of the retaining ring body is equal to the outer diameter of the main ring body.

[0009] Furthermore, the mounting seat, the main ring body, the supporting protruding ring and the surrounding ring body are integrally formed.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model is provided with a retaining ring coaxially on the outside of the supporting ring. When the automatic feeding equipment places the valve disc on the positioning tooling, the supporting convex ring supports the inner part of the valve disc, and the retaining ring supports the outer part of the valve disc, thereby effectively increasing the contact area between the valve disc and the tooling, ensuring that the valve disc is automatically fed into place, so that the valve disc is stably mounted on the wax-coated rod body, and effectively solving the problem of frequent failure of the valve disc to be automatically fed into place. After the riveting process, the qualified rate of the wax-coated assembly is ensured, and through use verification, the qualified rate is increased from 98% to 100%.

The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0020] Example 1: Please refer to the attached Figure 2 and attached Figure 3 A positioning tool for a wax package assembly riveted, comprising an integrally formed mounting seat 1, a main ring body 2, a supporting convex ring 3 and a surrounding ring body 4, wherein the mounting seat 1 is sleeved on the lower end of the main ring body 2, the supporting convex ring 3 and the surrounding ring body 4 are located at the top of the main ring body 2, and the surrounding ring body 4 is coaxially sleeved on the outside of the supporting convex ring 3, and the mounting seat 1, the main ring body 2, the supporting convex ring 3 and the surrounding ring body 4 are all coaxially arranged; the top end face of the supporting convex ring 3 is flush with the top end face of the surrounding ring body 4; the outer diameter of the surrounding ring body 4 is equal to the outer diameter of the main ring body 2, and the inner diameter of the supporting convex ring 3 is larger than the inner diameter of the main ring body 2, so that the through hole on the central axis of the positioning tool forms a stepped hole structure.

[0021] When used, the positioning fixture is installed on the riveting base through the mounting seat 1. During production, the wax-coated rod body is first inserted into the through hole from the top of the positioning fixture through the automatic feeding equipment. The protruding part of the wax-coated rod body is located inside the supporting convex ring 3 and partially exposed. Then the valve disc is placed on the positioning fixture through the automatic feeding equipment, and the valve disc is sleeved on the exposed part of the protruding part of the wax-coated rod body. At this time, the supporting convex ring 3 supports the inner part of the valve disc, and the retaining ring body 4 supports the outer part of the valve disc, thereby effectively increasing the contact area between the valve disc and the fixture, ensuring that the valve disc is automatically fed into place; finally, riveting is performed to connect the wax-coated rod body to the valve disc.
