Description

Technical Field

[0001] This utility model relates to the technical field of milling fixtures, specifically to a 120 main valve body milling side panel fixture. Background Technology

[0002] The 120 main valve body refers to the main control valve body assembly with a nominal diameter of DN120. It is commonly found in hydraulic or fluid control systems. Its core functions include flow channel control, pressure port integration, and valve core drive mechanism mounting base. The material is usually ductile iron.

[0003] The 120 main valve body requires milling of its side surfaces during machining. This milling process necessitates clamping the main valve body onto a worktable. Currently, existing milling clamping fixtures typically only clamp a single main valve body at a time, and there is no clamping mechanism specifically designed for the main valve body. Therefore, the clamping process is time-consuming and inefficient. Utility Model Content

[0004] To address the aforementioned issues, namely the time-consuming and inefficient clamping and fixing process during the milling of the 120 main valve body, this utility model proposes a milling fixture for the side of the 120 main valve body. The fixture includes a base plate with a vertical plate perpendicular to it. A screw is threaded onto the vertical plate, perpendicular to the vertical plate. It also includes a pressure plate with two valve body bodies symmetrically arranged about the screw between the pressure plate and the vertical plate. The sides of the valve body bodies face upwards. A U-shaped notch is provided on the pressure plate, covering the screw. An adjusting nut is threaded onto the screw, abutting against the pressure plate to simultaneously clamp the two valve body bodies.

[0005] A further feature of this invention is that: a pad is provided at each end of the pressure plate, the pad is vertically arranged, the pad is disposed on the side surface of the pressure plate near the valve body, and the pad abuts against the valve body.

[0006] A further feature of this invention is that two cylindrical pins are provided on the pad corresponding to the mounting hole at the top of the valve body, for positioning in conjunction with the mounting hole at the top of the valve body.

[0007] A further feature of this invention is that two positioning pins are provided on the upright plate, and the positioning pins are provided corresponding to the mounting holes on the surface of the valve body near the upright plate, so as to cooperate with the mounting holes on the surface of the valve body near the upright plate for positioning.

[0008] A further feature of this invention is that a support bolt is threadedly connected to the base plate corresponding to the valve body.

[0009] A further feature of this invention is that a corner brace is provided on the side surface of the upright plate opposite to the valve body, the side of the corner brace is connected to the upright plate by bolts, and the bottom edge of the corner brace is connected to the base plate by bolts.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. By cooperating with the screw and the pressure plate, it is possible to clamp two valve bodies simultaneously, thereby greatly reducing clamping time and improving clamping efficiency.

[0012] 2. By setting the cylindrical pin and locating pin to correspond to the mounting holes on the valve body, a faster clamping process for the valve body can be achieved, further improving the clamping efficiency before the milling of the side of the 120 main valve body.

[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] refer to Figure 1 A milling fixture for the side of a 120 main valve body is proposed, including a base plate 1, on which an installation groove 11 is provided, the installation groove 11 is arranged parallel to its long side, and a vertical plate 2 is installed in the installation groove 11. The vertical plate 2 is connected to the base plate 1 by bolts and is arranged perpendicular to the base plate 1.

[0019] Two vertical plates 2 are provided, and screws 3 are threadedly connected to the vertical plates 2. The screws 3 are set perpendicular to the vertical plates 2. A pressure plate 4 is also included, with two valve bodies 6 positioned between the pressure plate 4 and the vertical plates 2. The two valve bodies 6 are symmetrically arranged about the screws 3. The two ends of the pressure plate 4 abut against the tops of the two valve bodies 6 respectively, thereby pressing the valve bodies 6 tightly between the pressure plate 4 and the vertical plates 2. It should be noted that the sides of the valve bodies 6 are facing upwards, that is, the milling surface of the valve bodies 6 faces upwards, and the bottom of the valve bodies 6 abuts against the vertical plates 2.

[0020] The bottom of the pressure plate 4 has a U-shaped notch 41 facing the same direction. The U-shaped notch 41 covers the screw 3. The screw 3 is threaded with an adjusting nut 31. The adjusting nut 31 is set against the pressure plate 4. That is, rotating the adjusting nut 31 can squeeze the pressure plate 4 to move towards the valve body 6, thereby reducing the distance between the pressure plate 4 and the vertical plate 2, and realizing the clamping effect on the valve body 6.

[0021] The pressure plate 4 is also welded with pads 5 at both ends. The pads 5 are set vertically and are located on the side surface of the pressure plate 4 near the valve body 6. The pads 5 abut against the valve body 6, that is, the pressure plate 4 clamps the valve body 6 through the pads 5. The pads 5 can increase the contact area with the valve body 6, making the clamping more stable.

[0022] refer to Figure 3 The pad 5 is welded with two cylindrical pins 51 corresponding to the mounting hole at the top of the valve body 6. When the valve body 6 is clamped, the cylindrical pins 51 on the pad 5 can be inserted into the mounting hole at the top of the valve body 6, thereby achieving the purpose of matching and positioning with the mounting hole.

[0023] refer to Figure 2 The upright plate 2 is provided with two positioning pins 21. The positioning pins 21 are set with mounting holes on the side surface of the valve body 6 near the upright plate. During installation, the two positioning pins 21 can be inserted into the mounting holes on the side surface of the valve body 6 near the upright plate 2, thereby achieving the purpose of positioning with the mounting holes.

[0024] The base plate 1 is also threaded with a support bolt 7 corresponding to the valve body 6. The nut of the support bolt 7 abuts against the valve body 6 to support the valve body 6.

[0025] It should be noted that both the screw 3 and the support bolt 7 are threaded with lock nuts. Specifically, the lock nut on the screw 3 is positioned between the pressure plate 4 and the vertical plate 2, abutting against the vertical plate 2 to lock the connection between the screw 3 and the vertical plate 2. Similarly, the lock nut on the support bolt 7 is positioned between the nut and the base, abutting against the base plate 1 to lock the connection between the support bolt 7 and the base plate 1.

[0026] An angled brace 8 is provided on the side of the upright plate 2 away from the valve body 6. The side of the angled brace 8 abuts against the upright plate 2 and is connected by bolts. The bottom edge of the angled brace 8 abuts against the bottom plate 1 and is also connected by bolts. The angled brace 8 can support the upright plate 2 and prevent the upright plate 2 from deforming.

[0027] In summary, the cooperation between screw 3 and pressure plate 4 enables simultaneous clamping of two valve body bodies 6, thereby significantly reducing clamping time and improving clamping efficiency. By aligning cylindrical pin 51 and locating pin 21 with the mounting holes on the valve body body 6, a faster clamping process for the valve body body 6 can be achieved, further improving clamping efficiency before the milling of the side of the 120 main valve body.
