[0002] Pneumatic rod mainly utilizes the variable state generated in the compression process of gas in cylinder pipe, and can be widely applied in appliances needing height adjustment. Pneumatic rod is mainly composed of hollow outer tube, piston and piston rod. When the hollow outer tube of pneumatic rod is processed, the end of the hollow outer tube needs to be sealed and welded by using an end sealing welding machine.

[0016] In order to make those skilled in the art more understand the technical scheme of the utility model, the following will be combined with the attached Figs. 1-3 The utility model is further analyzed.

[0017] As Figs. 1-3 shown, a kind of air pressure rod outer tube end seal detection mechanism, including base 1, lifting seat 2 and detection assembly, the top of the base 1 is vertically upwards and is equipped with guide rod 3, the lifting seat 2 is vertically and horizontally arranged on the guide rod 3 by linear bearing, middle part is driven and is connected with the screw rod 4 of its lifting, the detection assembly includes air cylinder 5, mounting plate 6, detection rod 7 and proximity switch 8, the air cylinder 5 is hung upside down in one side of the lifting seat 2, the mounting plate 6 is connected and arranged at the bottom end of the piston rod of the air cylinder 5, the detection rod 7 is vertically and horizontally arranged on the mounting plate 6 by linear bearing, its outer periphery is equipped with spring 9, the proximity switch 8 is arranged on the mounting plate 6, and is arranged above the rear end of the detection rod 7.

[0018] In the embodiment, preferably, the top end of the lead screw 4 is drivingly connected with an adjusting hand wheel or a speed reduction motor to drive the lifting seat 2 to ascend or descend, so as to adjust the height position of the detection rod 7 to adapt to the detection of the gas pressure rod outer pipe of different lengths.

[0019] In the embodiment, preferably, the mounting plate 6 is provided in a Z-shaped structure, the bottom end of the piston rod of the cylinder 5 is connected with the top of the mounting plate 6, the proximity switch 8 is arranged at the middle part of the mounting plate 6, and the detection rod 7 is arranged at the bottom of the mounting plate 8.

[0020] In the embodiment, preferably, the detection rod 7 and the proximity switch 8 are respectively provided with two groups, one group of the detection rod 7 corresponds to one group of the proximity switch 8, and two groups of the gas pressure rod outer pipes can be detected at one time.

[0021] In the embodiment, preferably, the bottom of the detection rod 7 is integrally provided with a round plate 10, the round plate 10 is used for expanding the horizontal area of the bottom of the detection rod 7, so as to avoid that the detection rod 7 directly penetrates through the inner hole of the sealing ring and causes the detection failure, a nut 11 is threadedly connected with the top of the detection rod 7, the nut 11 is used for preventing the top of the detection rod 7 from falling off from the linear bearing, and the spring 9 is arranged between the linear bearing of the detection rod 7 and the round plate 10.

[0022] The working principle of the utility model is as follows: first, according to the length of the gas pressure rod outer pipe, the lifting seat 2 is driven to ascend or descend by the lead screw 4, so as to adjust the height position of the detection rod 7, when the gas pressure rod outer pipe is conveyed below the detection rod 7 by the feeding mechanism of the gas pressure rod outer pipe end sealing welding machine, the cylinder 5 drives the detection rod 7 to descend and insert into the port of the gas pressure rod outer pipe; at this time, if the port of the gas pressure rod outer pipe is provided with a sealing ring, the round plate 10 at the bottom of the detection rod 7 is arranged on the sealing ring, the detection rod 7 is lifted by the reverse force, the nut 11 at the top of the detection rod 7 is lifted to trigger the detection end of the proximity switch 8, and the signal is transmitted to the numerical control system of the gas pressure rod outer pipe end sealing welding machine, so that the welding mechanism normally works to perform laser welding on the connecting part between the inner wall of the gas pressure rod outer pipe and the sealing ring; if the port of the gas pressure rod outer pipe is not provided with the sealing ring, when the cylinder 5 drives the detection rod 7 to descend and insert into the port of the gas pressure rod outer pipe, the round plate 10 at the bottom of the detection rod 7 is not hindered by the sealing ring, the detection rod 7 is not lifted by the reverse force, and therefore the proximity switch 8 is not triggered, and the signal is not transmitted to the numerical control system of the gas pressure rod outer pipe end sealing welding machine, so that the welding mechanism does not work.
