[0012] In the accompanying drawings: 1. Air pressure signal controller; 2. Water vapor filter regulating valve; 3. One-way solenoid valve; 4. Workpiece fixing airtight pin; 5. Alarm device. DETAILED DESCRIPTION
[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0014] Example
[0015] See also Figure 1 The utility model provides a technical solution: a fixture airtightness detection device, including an air pressure signal controller 1, the back of the air pressure signal controller 1 is connected to a water vapor filter regulating valve 2, the water vapor filter regulating valve 2 is connected to a one-way solenoid valve 3 through a pipeline, the one-way solenoid valve 3 is connected to a workpiece fixing airtight pin 4 through a pipeline, the workpiece fixing airtight pin 4 is provided with an air pressure sensor, and the air pressure sensor is electrically connected to the air pressure signal controller 1.
[0016] Furthermore, the air pressure signal controller 1 is connected to an alarm device 5 via electrical wires.
[0017] Furthermore, the air pressure signal controller 1 and the alarm device 5 are connected to a terminal via a common wire.
[0018] Furthermore, a plurality of workpiece fixing airtight pins 4 can be provided.
[0019] In this embodiment, the workpiece fixing airtight pin 4 is fixed on the product fixture. When the product fixture is clamped, a signal is given to open the one-way solenoid valve 3 to allow the air source to enter the workpiece fixing airtight pin 4 to detect the pressure. When it is within the set range, the air pressure signal controller 1 will not output an alarm signal to the alarm device 5. If the product is not installed properly and the pressure is insufficient, the alarm device 5 will receive an alarm, and the machine tool cannot be started at this time.
