Embodiment 1
[0022] Embodiment one, as figure 1 As shown, a pneumatic gun error prevention system is used in the production system of car seats, including a controller, which is preset with a tightening program corresponding to multiple bolts on the assembly line and used for tightening the multiple bolts. the number of shots of an air-operated gun;
[0023] The position switch detection device connected with the controller is used to detect whether the bolt to be assembled is on the assembly tool, so as to start the corresponding tightening program; at the same time, this signal is also the activation signal for the initialization and reset of the bolt tightening cycle; through the assembly tool A photoelectric switch is installed on the top, which is used to detect whether the bolt to be assembled is on the assembly tool, so as to start the corresponding tightening program; at the same time, this signal is also the activation signal for the initialization and reset of the tightening work...

The invention relates to a pneumatic gun mistake-proofing system, belonging to the technical field of installation of automobile seats. The pneumatic gun mistake-proofing system includes a controller, a position switch detection device, a pneumatic gun device and a gas flow detection device, wherein a tightening program corresponding to a plurality of bolts in an assembly line and the operating times corresponding to the pneumatic gun for tightening the plurality of bolts are preset; the position switch detection device is used for detecting whether the bolt to be assembled is on an assembly fixture, so as to initiate the corresponding tightening program; the pneumatic gun device is used for tightening the bolt; the gas flow detection device is used for detecting the flow state signals of the compressed air of the pneumatic gun device; after the pneumatic gun operates qualifiedly at a time, the switch signal on the gas flow detection device is transmitted to the controller, and the controller counts the qualified operating times of the pneumatic gun. According to the pneumatic gun mistake-proofing system, the mistake-proofing function the same as an electric torque gun is ensured, and the cost of the pneumatic gun mistake-proofing system is far lower than that of the electric torque gun.
Description
technical field [0001] The invention relates to a pneumatic gun error prevention system, which belongs to the technical field of car seat installation. Background technique [0002] Pneumatic torque wrench is widely used in the production and assembly of various factories, mainly used for the fastening of some bolt terminals with a torque value of 10NM-40NM. This pneumatic adjustable fixed torque wrench has the characteristics of high torque accuracy (7-10%), good stability, convenient use, easy maintenance, and moderate price. However, in the modern assembly industry, the whole system has higher and higher requirements for tool integration, and the tool itself and the whole system must be able to carry out effective information transmission and interlocking cooperation. However, due to the structure of the pneumatic wrench itself, it is obviously impossible to meet this requirement. This makes it impossible to effectively monitor and track the state of the pneumatic torqu...
