[0022] This part will describe the specific embodiments of the present application in detail, the preferred embodiments of the present application are shown in the drawings, the role of the drawings is to supplement the description of the text part with graphics, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the present application, but it cannot be understood as a limitation on the protection scope of the present application.

[0023] With reference to Figures 1-4 , the present application embodiment a pneumatic servo valve for a robot, it includes: servo valve body 2, the servo valve body 2 upper and lower two surfaces middle part are all arc convex, the servo valve body 2 upper and lower two surfaces are all provided with a plurality of drainage grooves 4, drainage groove 4 does not extend to the convex part of servo valve body 2, drainage groove 4 cooperates with the shape of servo valve body 2 shell, avoids oil dirt, water stain to adhere to the surface of servo valve body 2, avoids the corrosion of oil dirt, water stain to the shell of servo valve body 2, the outer surface of servo valve body 2 is fixedly connected with mounting shell 1, mounting shell 1 completely wraps servo valve body 2, its mounting shell 1 is composed of rubber block and shell, mounting shell 1 and the shell of servo valve body 2 itself cooperate with each other, improve the installation convenience of pneumatic servo valve, improve the ability of pneumatic servo valve to resist negative stress, wherein mounting shell 1 is made into one whole by hot melting two shells, this way can improve the flatness and sealing effect of mounting shell 1, wherein only the shell part of mounting shell 1 is connected by hot melting.

[0024] The left and right ends of the servo valve body 2 are fixedly connected with docking protection tubes 3. The end of the docking protection tube 3 away from the servo valve body 2 passes through the mounting shell 1. The docking protection tube 3 prevents the connection node between the servo valve body 2 and the mounting location from being exposed. The docking protection tube 3 is made of silicone, which has the characteristic of shrinking when heated, which can further improve the sealing effect of the installed pneumatic servo valve.

[0025] An opening 5 is formed at the penetration point of the connecting protective tube 3. Multiple ventilation slots 9 are provided on the inner wall of the opening 5. The ventilation slots 9 extend into the interior of the mounting housing 1. An air guide slot 6 is provided inside the mounting housing 1. The air guide slot 6, ventilation slot 9, and air exchange chamber 7 are interconnected. There are two air exchange chambers 7 inside the mounting housing 1. The two air exchange chambers 7 are located on the upper and lower sides of the servo valve body 2. The air exchange chambers 7 are arc-shaped. The above structures work together to improve the ventilation effect inside the mounting housing 1. The surface of the servo valve body 2 and the slots inside the mounting housing 1 are all fixedly connected with a smooth coating 8. The smooth coating 8 improves the anti-adhesion ability of the internal components of the pneumatic servo valve.

[0026] A debris collection box 10 is fixedly connected to the lower surface of the mounting housing 1. The debris collection box 10 communicates with the ventilation chamber 7 located below. The debris collection box 10 facilitates the collection of oil and water stains generated during the operation of the pneumatic servo valve. Two baffles 11 are fixedly connected inside the debris collection box 10. The two baffles 11 are distributed vertically opposite to each other. Both baffles 11 are tilted downwards, and the tilting directions of the two baffles 11 are opposite. The baffles 11 prevent oil and water stains from flowing back. The upper baffle 11 tilts to the left, and the lower baffle 11 tilts to the lower right. The staggered tilting directions of the two baffles 11 further prevent oil and water stains from flowing back. A mounting groove 12 is provided on the lower surface of the mounting housing 1. The debris collection box 10 is located inside the mounting groove 12. The mounting groove 12 prevents the debris collection box 10 from affecting the installation stability of the pneumatic servo valve.

[0027] Working principle: When installing the valve, directly install the mounting housing 1 in the designated position, and then connect the connecting pipe to the servo valve body 2 through the docking protection pipe 3. At this time, a blower can be used to heat the docking protection pipe 3 to soften and shrink it, thereby further improving the installation sealing of the pneumatic servo valve. Then the pneumatic servo valve can be used. When the pneumatic servo valve is working, the airflow passes through the ventilation slot 9, the air guide slot 6, and the air exchange chamber 7 through the mounting housing 1. During the operation of the servo valve body 2, due to the presence of the smooth coating 8, the sprayed oil mist cannot adhere to the surface of the servo valve body 2. Under the influence of gravity, the protrusions on the surface of the servo valve body 2, the air guide slot 6, and the air exchange chamber 7, the oil mist slowly flows down into the interior of the debris collection box 10. The oil mist entering the debris collection box 10 is restricted by the baffle 11 and cannot flow back into the interior of the mounting housing 1. If water vapor appears inside the mounting housing 1, it will also flow down into the interior of the debris collection box 10 after the water vapor forms water droplets.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
