Description

Technical Field

[0001] The utility model relates to the technical field of valves, and particularly relates to a double-drilling tooling for a plug valve. Background Art

[0002] A plug valve is a rotary valve with a closing member or a plunger shape. By rotating, the passage openings on the valve plug communicate or separate from the passage openings on the valve body to achieve opening or closing of the valve. After the plug valve switch is produced, holes need to be drilled symmetrically on the left and right sides at the upper end of the plug valve switch. Workers hold the plug valve switch by hand and place it on the workbench, and a double-hole drilling machine drills holes on both sides of it. The positioning is inaccurate, resulting in position deviation of the holes on both sides, and putting hands under the drilling machine will pose a danger to the personal safety of the workers.

[0016] The embodiments of the present utility model will be introduced in detail below with reference to the drawings.

[0017] Refer to Figures 1 to 4 , the present utility model provides a double-drilling tooling for a cock valve, which is installed on a double-hole drilling machine and includes a bottom plate 1 installed on the workbench of the double-hole drilling machine. A fixed block 3 is vertically arranged on the right side of the upper end of the bottom plate 1. A movable block 4 driven by a cylinder 7 is slidably fitted left and right in the middle of the upper end of the bottom plate 1. A stabilizing block 2 is vertically arranged on the left side of the upper end of the bottom plate 1. The cylinder 7 is arranged rightward on the stabilizing block 2. The piston rod of the cylinder 7 is connected to the movable block 4. A fixed clamping plate 5 is arranged at the top of the fixed block 3. A movable clamping plate 6 corresponding to the fixed clamping plate 5 is arranged at the top of the movable block 4. Clamping grooves for positioning and clamping are provided on the fixed clamping plate 5 and the movable clamping plate 6. The cylinder drives the movable block to drive the movable clamping plate to move leftward, and the staff places the cock valve switch on the clamping groove of the fixed clamping plate fittingly. Then the cylinder drives the movable block to drive the movable clamping plate to move rightward to reset, and the clamping groove clamps the cock valve switch with accurate positioning. Subsequently, the cock valve switch is drilled with two holes by a double-hole drilling machine. After the drilling is completed, the cylinder drives the movable clamping plate to move leftward to loosen the cock valve switch.

[0018] A guide rod 8 passing through the movable block 4 is horizontally arranged between the fixed block 3 and the stable block 2, and guide sleeves 9 for the smooth fitting of the guide rod 8 are symmetrically arranged on the left and right sides of the movable block 4. The guide rod and the guide sleeve have a guiding function to ensure the accuracy and stability of the sliding of the movable block.

[0019] Refer to Figure 1 , Figure 3 , counterbores are symmetrically arranged on the front and rear sides of the upper end of the bottom plate 1. The counterbores can hide the bolts and prevent the raised bolts from interfering when cleaning the bottom plate between the movable block and the fixed block.

[0020] A baffle 10 is vertically arranged at the rear ends of the fixed block 3 and the stable block 2. The baffle can block the copper chips splashing backward, making the copper chips fall onto the bottom plate, so as to prevent them from falling into the T-shaped groove at the rear side of the workbench. Subsequently, only the copper chips on the bottom plate need to be cleaned.

[0021] A cover plate 11 is horizontally arranged at the front end of the bottom plate 1. After the plug valve switch is produced, holes need to be drilled symmetrically on the left and right sides of the upper end of the plug valve switch. During the drilling process, a lot of copper chips will fall into the T-shaped groove of the double-hole drilling machine workbench. Since the drilling position is in the front, they generally fall on the front side of the T-shaped groove, making it difficult to clean and collect the copper chips subsequently. The cover plate can cover the front side of the T-shaped groove, preventing the copper chips from entering the front side of the T-shaped groove.

[0022] The upper end surface of the cover plate 11 is inclined from the back upper to the front lower. The above setting can make the copper chips falling on the cover plate slide down automatically.

[0023] The double-drilling tooling for the plug valve of the present utility model: The movable clamping plate is driven by a cylinder to move left and right to clamp and loosen the plug valve switch, with accurate positioning and convenient operation.

[0024] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
