[0002] Vent valves are common equipment in the industrial and engineering fields. They are mainly used to discharge and control gas, steam or liquid media in pipelines, containers or equipment. Their core functions are to release pressure, discharge media, empty, exhaust or emergency pressure relief.

[0003] The vent valve cover has a specific shape that adapts to the valve body. The processing technology of the vent valve cover includes the processing of the inclined hole. Due to the specific shape of the vent valve cover, when processing its inclined hole, it is usually necessary to use multiple tools to clamp it so that it can be installed in a working condition suitable for drilling the inclined hole. Moreover, since the clamping requires the cooperation of multiple tools, it is difficult to adjust the processing angle after the clamping is completed.

[0004] Therefore, it is now urgent to design a tooling specifically for processing the oblique hole of the vent valve cover to meet the purpose of rapid installation and rapid adjustment of the vent valve cover. Utility Model Content

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] refer to Figure 1 The utility model proposes a tool for processing the inclined hole of the vent valve cover, including a clamping handle 1, which is arranged as a stepped shaft type, the axis of the clamping handle 1 is arranged horizontally, and the end with a small diameter of the clamping handle 1 is used for rotation connection with the drilling machine platform, thereby realizing the rotation movement of the clamping handle 1.

[0022] The clamping handle 1 is connected to a clamping mechanism 2 for clamping the valve cover body 3. An avoidance groove 211 is provided on the clamping mechanism 2 corresponding to the inclined hole of the valve cover body 3, so that when the inclined hole is machined with a drill bit, interference between the clamping mechanism 2 and the drill bit can be avoided.

[0023] An installation groove 11 is provided at one end of the clamping handle 1 close to the clamping mechanism 2, that is, a installation groove 11 is provided at the end with a larger diameter of the clamping handle 1. The installation groove 11 is provided at the center of the clamping handle 1. Two countersunk holes and a pin hole are provided in the installation groove 11. The pin hole is coaxially arranged with the clamping handle 1, and the two countersunk holes are symmetrically arranged about the pin hole. The clamping mechanism 2 is installed in the installation groove 11 by a countersunk bolt, and a positioning pin is also provided on the corresponding pin hole of the clamping mechanism 2 for positioning the clamping mechanism 2 and the installation groove 11.

[0024] refer to Figure 2 The clamping mechanism 2 includes a mounting plate 21, which is mounted in the mounting groove 11 via countersunk bolts and positioned by the engagement of locating pins with pin holes. Specifically, the end of the clamping handle 1 closest to the mounting groove 11 is inserted into the mounting groove 11, and then the countersunk bolts are threadedly inserted through the countersunk holes to connect the mounting plate 21, thereby achieving the purpose of mounting the mounting plate 21 in the mounting groove 11.

[0025] A column 22 is also connected to the upper surface of the mounting plate 21 by bolts. The column 22 is arranged perpendicular to the mounting plate 21. The top of the column 22 is connected to a clamping arm 23 by two bolts. The clamping arm 23 is arranged perpendicular to the column 22, that is, the clamping arm 23 is parallel to the mounting plate 21. The clamping wall is bolted with a clamping bolt 231. The valve cover body 3 is arranged between the clamping arm 23 and the mounting plate 21, and the purpose of clamping the valve cover body 3 can be achieved by screwing the clamping bolt 231.

[0026] A gasket 24 is also provided between the clamping bolt 231 and the valve cover body 3. The gasket 24 is provided directly below the clamping bolt 231. The bottom end of the clamping bolt 231 is against the gasket 24, and the lower surface of the gasket 24 is in contact with the valve cover body 3, thereby preventing the clamping bolt 231 from directly contacting the valve cover body 3 and avoiding scratches on the surface of the valve cover body 3 during the process of screwing the clamping bolt 231.

[0027] A relief opening 241 is formed on the backing plate 24 at the inclined portion corresponding to the valve cover body 3 , ie, the relief opening 241 is formed to avoid the structure of the valve cover body 3 itself.

[0028] refer to Figure 3The upper surface of the mounting plate 21 is integrally provided with a mounting portion 25, which is designed in a diamond shape to match the valve cover body 3. The mounting portion 25 protrudes from the upper surface of the mounting plate 21, and a clearance hole 25 extends from top to bottom. A clearance hole 251 is defined in the middle of the mounting portion 25 to accommodate the circular end of the bottom of the valve cover body 3. Specifically, the inner diameter of the clearance hole 251 is the same as the diameter of the circular end of the bottom of the valve cover body 3. During installation, the cylindrical end of the bottom of the valve cover body 3 is inserted into the clearance hole 251 to achieve precise positioning of the valve cover body 3.

[0029] The mounting portion 25 also defines two positioning holes 252, symmetrically arranged about the relief hole 251. The positioning holes 252 correspond to the two circular holes used for mounting in the valve cover body 3. Specifically, after the cylindrical end of the valve cover body 3 is inserted into the relief hole 251, a pin or bolt is inserted through both the circular hole and the positioning holes 252 to limit the rotation of the valve cover body 3.

[0030] To sum up, the utility model utilizes the rotational connection between the clamping handle 1 and the drilling platform to achieve the purpose of rotating the clamped valve cover body 3. At the same time, the avoidance groove 211 is opened to cooperate with the drill bit to process the inclined hole of the valve cover body 3, thereby achieving the purpose of processing the inclined hole of the valve cover body 3. The clamping and adjustment process is simple and convenient.

[0031] refer to Figure 4 、 5 It should be noted that during processing, the inclined hole to be processed can be rotated to a vertical state through the rotation of the clamp, and then the horizontal position is adjusted to align the inclined hole to be processed with the drill bit before the inclined hole processing is carried out.
