[0002] During machining, a machine tool uses a pneumatic pressure detection device to determine whether the workpiece is clamped securely, allowing machining to proceed. Commonly used pneumatic pressure detection devices adjust the air pressure by varying the air hole contact gap. However, errors introduced by machining can cause the detected air pressure to become unstable, leading to false alarms on the machine tool and compromising machining quality and efficiency. Summary of the Invention

[0003] The utility model provides a gas detection device used on a fixture, which effectively ensures the numerical stability of the detected air pressure, prevents false alarms of machine tools, improves working efficiency and ensures processing quality.

The device is characterized in that a piston rod of the rotating oil cylinder is connected to a pressure plate, a through air passage is provided in the bolt corresponding to one end of the pressure plate on the rotating oil cylinder, a through hole is provided on the mounting base corresponding to the bolt at one end of the pressure plate, and a sealing block is provided at the end of the pressure plate corresponding to the air passage.

[0006] It is further characterized in that a pipe joint is provided on the through hole; a stepped through groove is provided at the end of the pressure plate, a T-shaped pressure block is provided in the stepped through groove, and the sealing block is connected to the T-shaped pressure block; a compression spring is provided in the stepped through groove corresponding to the upper end of the T-shaped pressure block, and an adjusting bolt is provided in the stepped through groove corresponding to the upper end of the compression spring; the sealing block is a polyurethane sealing block.

[0007] By adopting the above technical solution, the piston rod of the rotating cylinder is connected to the pressure plate, and a through air duct is provided in the bolt corresponding to one end of the pressure plate on the rotating cylinder, and a through hole is provided on the bolt corresponding to one end of the pressure plate on the mounting base. A sealing block is provided at the end of the pressure plate corresponding to the air duct. When the cylinder is tightened, the pressure plate moves downward, driving the sealing block to move downward, so that the sealing block contacts the screw rod, and continues to move downward to increase the force applied by the sealing block. The sealing block seals the air duct on the bolt, thereby achieving effective sealing and ensuring sealing performance. It effectively ensures the numerical stability of the detected air pressure, prevents false alarms of the machine tool, improves work efficiency, and ensures processing quality.

[0010] The specific implementation of the present utility model will be further described below with reference to the accompanying drawings.

[0011] See Figure 1 、 Figure 2 , a gas detection device used on a tooling fixture, which includes a rotating cylinder 1, which is connected to a mounting base 3 by three bolts 2 on the rotating cylinder 1, and a rotating cylinder piston rod 4 is connected to a pressure plate 5. A through air channel 6 is provided in the bolt 2 at one end of the rotating cylinder 1 corresponding to the pressure plate 5, and a through hole 7 is provided on the bolt 2 at one end of the mounting base 3 corresponding to the pressure plate. A sealing block 8 is provided at the end of the pressure plate 5 corresponding to the air channel 6. When the cylinder is tightened, the pressure plate moves downward, driving the sealing block to move downward, so that the sealing block contacts the screw, and continues to move downward to increase the force applied by the sealing block. The sealing block seals the air channel on the bolt, thereby achieving effective sealing and ensuring sealing performance. It effectively ensures the stability of the detected air pressure value, prevents false alarms of machine tools, improves work efficiency, and ensures processing quality.

[0012] A pipe joint 9 is provided on the through hole 7 to realize external connection of a pipeline.

[0013] A stepped through groove 10 is provided at the end of the pressure plate 5, a T-shaped pressure block 11 is provided in the stepped through groove 10, the sealing block 8 is connected to the T-shaped pressure block 11, and a compression spring 12 is provided at the upper end of the corresponding T-shaped pressure block 11 in the stepped through groove 10, and an adjusting bolt 13 is provided at the upper end of the corresponding compression spring 12 in the stepped through groove 10. The spring pressure is controlled by adjusting the bolt, thereby controlling the sealing performance of the seal. While ensuring the stable sealing of the sealing block, the flexibility of the sealing device is guaranteed, damage to the T-shaped pressure block and the sealing block is prevented, and the production cost is effectively reduced.

[0014] In this embodiment, the sealing block 9 is preferably a polyurethane sealing block.

[0015] In this embodiment, three bolts are used to connect the rotating cylinder to the mounting base. The three bolts can ensure the stability of the connection between the rotating cylinder and the mounting base. Of course, other numbers of bolts can also be used. In this embodiment, an internal opening in one of the three bolts is used to form a vent hole, which effectively saves materials and reduces production costs.

[0016] The working principle of the present invention will be described below with reference to the accompanying drawings:

[0017] The rotating cylinder 1 is pressed, and the pressure plate 5 moves downward to drive the sealing block 8 to move downward, so that the sealing block 8 contacts the screw 2. The downward movement increases the force exerted on the sealing block 8 by the compression spring 12. The sealing block 8 is deformed to a certain extent under the action of external pressure, sealing the airway 6, filling and closing the mechanical gap, maintaining close contact to achieve effective sealing, and ensuring sealing performance. It effectively ensures the numerical stability of the detected air pressure, prevents false alarms of the machine tool, improves work efficiency, and ensures processing quality.

[0018] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the scope of the technical solution of the utility model.
