[0002] A valve is defined as a device in a fluid system used to control the direction, pressure, and flow rate of a fluid. Valves allow the flow or stop of media (liquid, gas, powder) within piping and equipment, and can control their flow rate. The material of the valve body is selected according to different process media. Commonly used materials include cast iron, cast steel, stainless steel, carbon steel, plastic, and copper. After the valve body is cast, a grinding device is needed to polish its surface.

[0003] Existing grinding equipment typically places the cast valve body on a grinding table, requiring workers to secure it before operating the grinding mechanism. Due to limitations in human physical strength, it's difficult to guarantee consistency and precision in each grinding cycle. This not only affects the final product quality but also increases the cost of subsequent repairs and rework. Therefore, we need to propose a robotic tooling fixture device for grinding cast valve bodies. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5This utility model provides a technical solution: a tooling fixture device for grinding a casting valve body, including a grinding robot part 1 for grinding the casting valve body and a base 2. The grinding robot part 1 is fixedly installed on the base 2. A fixed seat 3 is bolted to one end of the base 2, and a support seat 4 is bolted to the other end of the base 2. A support groove 5 for supporting the casting valve body is opened at the top of the support seat 4. A clamping part 6 for clamping the bottom end of the casting valve body is provided at the bottom end of the support seat 4. A clamping part 7 for clamping the casting valve body is installed on the upper surface of the base 2.

[0024] The cast valve body is placed on the support base 4, with the lower surface of the valve body fitting against the inner cavity of the support groove 5. At the same time, the top of the fixing base 3 supports the bottom of the valve body. The clamping part 6 is activated to clamp and fix the bottom of the cast valve body, and the clamping part 7 is activated to clamp the top of the cast valve body. Finally, the cast valve body is polished by operating the polishing robot part 1, thereby avoiding manual fixing, improving the one-time fixation and accuracy of each polishing, reducing the impact on the final product quality, and reducing the cost of subsequent repair and rework.

[0025] The grinding robot part 1 includes a robotic arm 11, which is fixedly mounted on the upper surface of the base 2. A grinding device 12 is installed at the movable end of the robotic arm 11. During grinding, the operator operates the robotic arm 11 to change the direction of the grinding device 12, so that the grinding head of the grinding device 12 contacts the casting valve body for grinding, thus avoiding manual grinding and reducing the physical effort consumed by the operator. The grinding device 12 and the robotic arm 11 can be combined to form the LG-DM612 type grinding industrial robot.

[0026] The clamping part 6 includes an electric push rod 61, which is bolted to the upper surface of the base 2. The push rod part of the electric push rod 61 is bolted to a clamping seat 62. The bottom end of the support base 4 is provided with a square hole 63. The surface of the clamping seat 62 is slidably inserted into the inner cavity of the square hole 63. The other end of the clamping seat 62 is provided with a clamping structure. When the electric push rod 61 is activated, it pushes the clamping seat 62 to move, so that the clamping seat 62 passes through the square hole 63 and cooperates with the clamping structure to clamp the cast valve body.

[0027] The clamping structure includes a positioning seat 64, which is bolted to the upper surface of the base 2 and is located at the end away from the clamping seat 62. The surface of the clamping seat 62 is provided with a positioning groove 65, and the inner cavity of the positioning groove 65 engages with the surface of the positioning seat 64. The positioning seat 64 supports one side of the bottom end of the cast valve body. The clamping seat 62 moves towards the bottom end of the cast valve body through the square hole 63, so that the inner cavity of the positioning groove 65 contacts the surface of the bottom end of the cast valve body. The positioning groove 65 continuously pushes the bottom end of the cast valve body towards the positioning seat 64, thereby clamping the bottom end of the cast valve body.

[0028] The clamping part 7 includes a push rod cylinder 71. A fixed frame 72 is provided at the piston end of the push rod cylinder 71. A lever structure is rotatably connected to the inner cavity of the fixed frame 72. A clamping block 73 is provided at the other end of the lever structure. When the push rod cylinder 71 is activated, it pushes the fixed frame 72 to move upward, causing the fixed frame 72 to drive the lever structure to move. Through the lever structure, the clamping block 73 on the other side moves downward and contacts the upper surface of the cast valve body. The clamping block 73 presses down on the cast valve body, and the support seat 4 at the bottom provides support, thereby achieving the clamping state of the cast valve body.

[0029] The lever structure includes a movable frame 74, which is bolted to the upper surface of the base 2. The inner cavity of the movable frame 74 is rotatably connected to a support column 75 via a pivot. The top of the support column 75 has a movable groove, and the inner cavity of the movable groove is rotatably connected to a support plate 76 via a pivot pin. One end of the support plate 76 is rotatably connected to the inner cavity of a fixed frame 72 via a pivot, and the other end of the support plate 76 is connected to a clamping block 73. The fixed frame 72 drives one end of the support plate 76 to move upward. Due to the rotation of the support plate 76 and the inner cavity of the movable groove, the support column 75 and the movable frame 74 cooperate to pull the bottom end of the support plate 76. The support plate 76 is subjected to the pulling force, which causes the other end of the support plate 76 to drive the clamping block 73 to press downward, thus forming a lever principle.

[0030] The top of the clamping block 73 is fixedly connected to a threaded rod 8, and the upper surface of the support plate 76 is provided with a threaded hole 9. The outer surface of the threaded rod 8 is threadedly connected to the inner cavity of the threaded hole 9. Through the cooperation between the threaded rod 8 and the threaded hole 9, the clamping block 73 and the support plate 76 can be disassembled, making it convenient to replace the clamping block 73 after it is damaged.

[0031] The upper surface of the base 2 is provided with a mounting groove 10, and the inner cavity of the mounting groove 10 is provided with bolt holes. The mounting groove 10 is provided with several sets. The mounting base can be engaged with the bottom ends of the support base 4, the fixed base 3 and the positioning base 64, providing support for the bottom ends of the support base 4, the fixed base 3 and the positioning base 64, and improving the stability of the support base 4, the fixed base 3 and the positioning base 64 after they are installed on the base 2.

[0032] In practical use: Place the cast valve body on the support seat 4, with the lower surface of the valve body fitting against the inner cavity of the support groove 5. At the same time, the top of the fixed seat 3 supports the bottom of the valve body, and the positioning seat 64 supports the other side of the bottom of the cast valve body. Then, start the electric push rod 61 to push the clamping seat 62 to move, so that the clamping seat 62 passes through the square hole 63 and moves towards the positioning seat 64, so that the positioning groove 65 on the surface of the clamping seat 62 contacts the bottom of the cast valve body, and continues to move towards the positioning seat 64, pushing the other side of the cast valve body to contact the surface of the positioning seat 64, clamping the bottom of the cast valve body. Through the cooperation of the support groove 5 and the positioning groove 65, the same valve body is prevented from being placed on the tooling fixture at different angles.

[0033] Next, the push rod cylinder 71 is activated to push the fixed frame 72 upward. As the inner cavity of the support plate 76 rotates, the support column 75 and the movable frame 74 work together to pull the bottom end of the support plate 76. The support plate 76 is subjected to the pulling force, which causes the other end of the support plate 76 to drive the clamping block 73 to press downward, forming a lever principle to press down and clamp the upper surface of the cast valve body. Finally, the robotic arm 11 is operated to change the direction and position of the grinding equipment 12 to grind the cast valve body, thereby avoiding manual fixing, improving the one-time fixation and accuracy of each grinding, reducing the impact on the final product quality, and reducing the cost of subsequent repair and rework.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
