[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0019] Example:

[0020] Figure 1 It is a type of open-end locating pin assembly tooling. Figure 2 This is a schematic diagram of a concealed valve body, including a tooling frame 1. The tooling frame 1 is provided with multiple positioning pins 2 for positioning the valve body. The tooling frame 1 is also provided with a sliding member 3. The sliding member 3 is connected to an assembly 5. The assembly 5 is provided with a pressing part, a guide part, and a pressing tube 505. The pressing tube 505 passes through the guide part and is connected to the pressing part. The free end of the pressing tube 505 can carry an open positioning pin. The pressing part presses the open positioning pin down and assembles it into the hole of the valve body.

[0021] This utility model uses a positioning pin 2 to fix the valve body, and the opening positioning pin is sleeved on the lower pressure tube 505. The moving plate slides to the limit position, and the handle is moved upward to press the opening positioning pin into the valve body. This makes it easier for the operator to operate, reduces the assembly cycle, and reduces the deformation of the opening positioning pin.

[0022] The sliding member 3 includes a slide rail 301 disposed on the tooling frame 1, a slider 302 disposed on the slide rail 301, and a movable plate 303 fixed to the slider 302. The pressing part is disposed on the movable plate 303, and the movable plate 303 has an elongated hole to adjust the installation position.

[0023] The slide rail is also equipped with baffles at both ends for limiting movement. For example... Figure 2 As shown, the movable plate is moved away to facilitate fixing the valve body and to facilitate fitting the open positioning pin. After fixing the valve body, the movable plate is moved above the required hole. At this time, the positioning and limiting functions are achieved by using the limiting edge, which makes it easy to accurately position the hole.

[0024] A bracket 4 is fixed on the movable plate 303, and the pressing part is fixed to the pressing part; the pressing part includes a hinge seat 501, which is hinged to the bracket 4. The hinge seat 501 is also hinged to a connecting rod 502. The lower end of the connecting rod 502 is hinged to an arc-shaped arm 503, and the lower end of the arc-shaped arm 503 is hinged to the pressing tube 505; the hinge seat 501 is also fixed with a handle 506.

[0025] The guide section adopts a guide tube 504, which is fixed to the moving plate 303, and the pressing tube 505 passes through the guide tube 504.

[0026] The lower end of the pressure tube 505 is configured as a constricted section for installing the opening positioning pin. In this invention, the assembly is first moved to one side, and the opening positioning pin is fitted. The handle 506 is in a drooping state under its own weight. At this time, under the action of the hinge, the connecting rod 502, the arc arm 503, and the pressure tube 505 move upwards, and the opening positioning pin is located on the upper side of the valve body. The opening positioning pin is moved to directly above the hole, and the handle 506 is lifted. The connecting rod 502, the arc arm 503, and the pressure tube 505 move downwards, pressing the opening positioning pin into the hole.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
