AI Technical Summary
In the prior art, the gooseneck valve on the soot blower is prone to loosening during rotary turning due to uneven weight distribution, and there is a lack of dedicated turning fixtures for secure clamping.
A gooseneck valve turning fixture was designed, comprising a three-jaw chuck, extended jaws, a mounting plate, a counterweight, and a locking block. The combined use of the extended jaws and the locking block enhances the fixation of the lower support arm of the gooseneck valve, while the counterweight provides stability and prevents loosening.
This improves the clamping stability of the gooseneck valve, avoids instability caused by loosening during rotary turning, and ensures smooth machining.

The three-jaw chuck is characterized by having extended jaws on its jaws, an assembly plate at the bottom of the three-jaw chuck, a counterweight at the top of the assembly plate, a locking block at the bottom of the assembly plate, and a support arm positioning groove on the locking block.
[0005] The extended jaws consist of a connecting block and a clamping block. The connecting block is detachably mounted on the jaws of the three-jaw chuck by bolts, and the clamping block is mounted obliquely on the connecting block. Anti-slip textures are provided on the end face of the clamping block.
[0006] An inverted U-shaped anti-moving block is provided on the extended gripper located above. Threaded holes are opened at both ends of the anti-moving block, and horizontal locking screws are installed in the threaded holes.
[0007] The locking block has a threaded hole on its side wall that communicates with the support arm positioning groove, and a support arm locking screw is installed in the threaded hole.
[0008] An elevation platform is provided on the assembly plate, a three-jaw chuck is installed on the elevation platform, and the counterweight is an arc-shaped counterweight with its bottom surface coupled to the outer wall of the elevation platform.
[0009] The locking block is detachably mounted on the assembly plate by bolts.
[0010] The advantages of this utility model are: the addition of a locking block for the lower support arm of the gooseneck valve to fix the lower support arm, and the placement of a counterweight block opposite the locking block to improve the stability of the clamping and prevent loosening.

[0018] In the description of the embodiments of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, if terms such as "first" or "second" appear in the description of this invention, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0019] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
[0020] As shown in the attached figure, the present invention includes a three-jaw chuck 1 mounted on a lathe.
