[0023] 1) Structure of the square steel pipe cutting quick positioning device

[0024] The structure of the quick positioning device for square steel pipe cutting is mainly composed of four parts: an infrared sensing push plate 1, a linear module 2, a linear guide rail 3, and a bracket support 4. Figure 1-6 shown.

[0025] Infrared induction push plate 1: It is composed of a Z-shaped push plate and an infrared induction switch 101. The Z-shaped push plate is 520mm long, 80mm wide and 191.4mm high. It is composed of an infrared induction base plate 102, a connecting plate 103 and a slide plate 104. The infrared induction base plate 102 is provided with an infrared induction switch 101. The connecting plate 103 is connected to the infrared induction base plate 102 and the slide plate 104. The infrared induction switch 101 is connected to the cutting machine tool to sense whether a square steel pipe has arrived. The machine tool is stopped according to the equipment value, and then the Z-shaped push plate is pushed back to the specified position. The slide plate 104 is welded to the sliding block 204 of the linear module;

[0026] Linear module 2: It is composed of a push chute 201, a fall chain 203, a sliding block 204, an electric propeller 205, and a numerical control panel (206). The total length is 2300 mm, and the push chute is 80 mm wide. The fall chain 203 is designed on both sides of the push chute 201 to facilitate the movement of the entire linear module. The sliding block 204, the electric propeller 205, and the numerical control panel (206) are used to adjust the length of the square steel tube.

[0027] Linear guide 3: It consists of a track 303 with a length of 600 mm and a width of 20 mm, a slider 301 and a fixture 302. Three sliders 301 are connected under each linear module 2, so that the electric propeller can move laterally on the support platform 4, and the fixture 302 fixes the linear module 2 to the slider 301.

[0028] The support base 4 is composed of a frame 401 made of stainless steel square steel and six vertical columns 402, wherein the three short horizontal square steels in the frame 401 are respectively connected to the guide rails 303 in the three linear guide rails and are connected by welding.

[0029] 2) Use: Two adjustable solutions are adopted

[0030] CNC adjustment scheme 1

[0031] Step S1: The square steel is transported into the machine tool, and the machine tool stops transporting after it contacts the infrared ray 101 of the induction switch;

[0032] Step S2: There is a 50mm gap between the infrared ray of the induction switch and the push plate baffle 103 to buffer the impact force transmitted by the square steel to prevent direct collision with the baffle, and then the push plate 1 automatically moves forward 50mm minus the distance of the buffer zone to obtain the required length;

[0033] Step S3: After the square steel reaches the designated length for the first time, if the length of the square steel is different, the distance to be adjusted needs to be input on the numerical control panel 206, and the motor 205 drives the push plate 1 to push the square steel to the designated position to complete the adjustment.

[0034] Step S4: This tooling has three linear modules 2 that can adjust different lengths simultaneously.

[0035] CNC adjustment scheme 2

[0036] Step S1: Place the square steel into the sawing machine for transportation, set the cutting lengths of positions 1, 2, and 3 on the numerical control panel 206, and adjust the position of the induction push plate 1.

[0037] Step S2: Start the tooling, the motor 205 automatically moves into position, and the sawing machine starts and feeds the material.

[0038] Step S3: Feed the material to position 1 (assuming that position 1 arrives first), and the infrared sensor 101 stops feeding for 0.5S (to reduce impact force) after sensing it, and then continues feeding to positions 2 and 3 in the same way.

[0039] Step S4: After everything is in place, the cutting process is carried out, and the next cycle is carried out after unloading.

[0040] The use of this device can almost meet most of the length requirements of machine tool cutting, greatly improve production efficiency, avoid the impact of human factors on product quality, and provide a reference for machine tool cutting in the nuclear power and electrical workshops of Hualong One's subsequent projects.
