It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present utility model.
[0016] In addition, for the terms "first" and "second", they are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meanings of "several" and "a number of" are two or more, unless otherwise specifically and clearly defined.
[0017] Refer to the attached drawings. The throttle valve fixture tooling in this embodiment includes a base table 1, on which a gantry bracket 2 is provided. The gantry bracket 2 includes columns on both sides and a cross beam 21 at the top; an installation groove is provided on the cross beam 21, and the installation groove is a through structure, which enables the first clamping member 31 and the second clamping member 32 to be arranged in the installation groove; the first clamping member 31 and the second clamping member 32 are rotatably installed in the installation groove through a pin shaft 4, and the first clamping member 31 and the second clamping member 32 are arranged facing each other. To ensure the clamping force, the pin shaft 4 at the rotation center is located at a position slightly above the middle of the first clamping member 31 and the second clamping member 32.
[0018] Clamping portions 33 are provided at the tops of the first clamping member 31 and the second clamping member 32. Arc-shaped protrusions are provided on the facing sides of the clamping portions 33, which can clamp and fix the throttle valve body without leaving clamping marks and without damaging the valve body.
[0019] A cam 5 is provided in the middle below the first clamping member 31 and the second clamping member 32. The cam 5 is symmetrically designed, and the symmetric sides are straight edges 51, and the straight edges are connected by an arc segment 52. The cam 5 is installed on a first rotating motor 6, and the cam 5 drives the clamping portions 33 at the tops of the first clamping member 31 and the second clamping member 32 to open and close. Springs 7 are provided on the sides of the first clamping member 31 and the second clamping member 32 facing the columns, and the springs 7 drive the first clamping member 31 and the second clamping member 32 to keep in contact with the outer contour of the cam 5.
[0020] When the cam 5 rotates to the position where the most protruding parts of the arc segments 52 on both sides are in contact with the lower ends of the first clamping member 31 and the second clamping member 32, at this time, the first clamping member 31 and the second clamping member 32 are in a clamped state, and the clamping portions 33 at the upper ends firmly clamp the valve body 81 of the throttle valve 8. [[ID=ll]]
[0021] When the cam 5 rotates to the position where the straight edges 51 on both sides are in contact with the lower ends of the first clamping member 31 and the second clamping member 32, at this time, the first clamping member 31 and the second clamping member 32 are in a loosened state, and the clamping portions 33 at the upper ends are separated, and the valve body 81 of the throttle valve 8 can be taken and placed. By using the outer contour line of the cam to change the distance between the lower parts of the first clamping member and the second clamping member, the clamping portions above the first clamping member and the second clamping member are opened and closed, so as to complete the clamping and fixing of the throttle valve body, which is very convenient to use.
[0022] A second rotating motor 9 for driving the base table 1 to rotate is provided on the side of the base table 1, and the base table drives the first clamping member and the second clamping member to rotate 180 degrees. By arranging the second rotating motor 9 on the side of the base table, the base table 1 can be driven to rotate 180 degrees, so as to complete the assembly work of the left end face, upper end face and right end face of the valve body, with high assembly efficiency and saving installation costs.
