Detailed Implementation

[0021] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] like Figures 1-5 As shown, a three-dimensional tapping device for a fluoropolymer-lined ball valve includes a table 100. The table is provided with a ball valve clamping device 200 and a tapping device 300. The tapping device 300 includes a support shaft 310 with its lower end fixed to the table. The upper end of the support shaft is rotatably connected to a horizontal connecting arm 320 that can rotate on a horizontal plane. The free end of the horizontal connecting arm is rotatably connected to a first connecting bracket 330 that can rotate on a horizontal plane. The first connecting bracket is connected to a second connecting bracket 350 through a pair of parallel rods 340. The first connecting bracket, the two rods, and the second connecting bracket form a parallel four-bar linkage. An electric tapping assembly 360 is provided on the second connecting bracket. The ball valve is clamped on the ball valve clamping device 200. The horizontal connecting arm 320 can rotate 360° relative to the support shaft 310 on the horizontal plane. The first connecting bracket 330 can rotate 360° relative to the horizontal connecting arm 320 on the horizontal plane. The second connecting bracket 350 can move up and down relative to the first connecting bracket 330. This enables the electric tapping assembly to be adjusted back and forth, left and right, and up and down, which is beneficial for quickly adjusting the processing position, has good flexibility, and is convenient and practical.

[0024] In this embodiment, a gas strut 370 is connected between the first connecting bracket and one of the lever arms to push the lever arm upward. There are two gas struts 370, distributed on both sides. Under the action of the gas struts 370, the lever arm is initially in an upward position to lift the electric tapping assembly 360. Drilling causes the second connecting bracket to press down and compress the gas struts 370, which in turn lowers the electric tapping assembly.

[0025] In this embodiment, to avoid the power cord of the electric tapping assembly from getting tangled or interfering with the processing, both the horizontal connecting arm and the rod arm are hollow structures. The power cord 361 of the electric tapping assembly passes through the rotating end of the horizontal connecting arm, exits from the free end of the connecting arm, passes through the end of the rod arm toward the first connecting bracket, and exits from the end of the rod arm toward the second connecting bracket in sequence. The power cord 361 adopts an internal routing method.

[0026] In this embodiment, a rotating sleeve 311 is fitted on the upper end of the support shaft to rotate with it, and the rotating end of the horizontal connecting arm is fixedly connected to the rotating sleeve; the free end of the horizontal connecting arm is rotatably connected to a vertical rotating shaft 321, and the first connecting bracket is fixedly connected to the vertical rotating shaft.

[0027] In this embodiment, the ball valve clamping device 200 includes a base plate 210. A horizontal lead screw 230 driven by a pneumatic motor 220 is provided on the upper side of the base plate. Support seats 240 are provided on both sides of the horizontal lead screw. Fixed clamping blocks 250 and movable clamping blocks 260, driven to reciprocate by the horizontal lead screw, are provided on the upper sides of the two support seats. The ball valve is placed between the fixed clamping block 250 and the movable clamping block 260. The pneumatic motor 220 drives the horizontal lead screw to rotate, thereby causing the movable clamping block to move towards the fixed clamping block to clamp the ball valve.

[0028] In this embodiment, the bottom of the movable clamping block is provided with a seat body 261 that extends into the middle of the two support seats. The seat body is provided with a threaded hole for the horizontal lead screw to pass through and engage with it. The support seat is provided with a convex rail 241 on the upper part of the side facing the middle. The upper sides of the seat body are provided with sliding grooves 262 that are adapted to the convex rail.

[0029] In this embodiment, the base plate 210 is pressed and fixed to the table surface by pressure plates 270 on both sides, and the pressure plates are connected to the table surface by bolts.

[0030] In this embodiment, the electric tapping assembly 360 includes a motor 362, a reducer 363, a tap chuck 364, and a tap 365. The electric tapping assembly 360 is prior art and can be purchased directly from the market.

[0031] In this embodiment, a handle 351 is fixedly connected to the side of the second connecting bracket. The handle 351 facilitates the manipulation and movement of the second connecting bracket.

[0032] Unless otherwise stated, if any of the technical solutions disclosed in this utility model discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any person skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of this utility model. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this utility model.

[0033] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).

[0034] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0035] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
