[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0031] This invention provides a tee pipe welding machine.

[0032] In this embodiment, refer to Figure 1-7 The tee pipe welding machine includes:

[0033] Feeding mechanism 1 is used to feed unwelded tee pipes. After the short pipe 38 is pre-tightened onto the through hole 39 of the long pipe 37, it is fed through the feeding mechanism.

[0034] The feeding mechanism 2 includes a feeding cylinder 3, a positioning mold 4 connected to the output end of the feeding cylinder, and a lifting cylinder 5 disposed below the positioning mold. The positioning mold is provided with a T-shaped pipe groove 6 adapted to the T-shaped pipe. The feeding mechanism is used to deliver the unwelded T-shaped pipe to the designated work station. The lifting cylinder is used to lift the T-shaped pipe placed on the positioning mold, so as to facilitate the subsequent clamping mechanism to clamp it.

[0035] The clamping mechanism 7 includes a clamping device 8 for clamping the tee pipe and a rotary power mechanism 9 for driving the clamping device to rotate. After the clamping device clamps and fixes the tee pipe, the rotary power mechanism drives the clamping device to rotate. The welding mechanism welds the short pipe onto the long pipe. The rotary power mechanism can be an electric motor, and the clamping device can be an existing cylinder claw. The clamping device is connected to the rotary power mechanism.

[0036] The top pressing assembly 10 is positioned opposite the clamping mechanism and is used to assist in pressing the short pipe of the tee pipe onto the long pipe of the tee pipe. The short pipe is pressed onto the long pipe by the pressing assembly to prevent separation during welding and improve welding quality.

[0037] Welding mechanism 11, which is disposed between clamping mechanism and pressing assembly, is used to weld the short pipe and long pipe of tee pipe into one piece.

[0038] Specifically, the feeding mechanism includes a vibratory feeder 12, a feeding track 13 connected to the vibratory feeder, and a guide cylinder 14 connected to the feeding track. The guide cylinder has a three-way pipe channel 15 for the passage of the three-way pipe. The end of the guide cylinder is connected to the positioning mold. The guide cylinder is fixed on the base plate 17 by a support plate 16.

[0039] After adopting the above technical solution, the T-shaped pipe falls from the T-shaped pipe channel of the guide cylinder into the T-shaped pipe groove of the positioning mold at the end of the guide cylinder through the vibrating plate and the feed rail.

[0040] Specifically, the feeding mechanism also includes a base 18 fixed on the base plate and a cylinder plate 19 fixed on the base. The feeding cylinder is fixed on the cylinder plate. The lifting cylinder is fixed on the bottom of the positioning mold. The output end of the lifting cylinder passes through the positioning mold and extends into the T-shaped pipe groove to lift the T-shaped pipe. A positioning cylinder 21 is fixed on the cylinder plate. The output end of the positioning cylinder is provided with a positioning rod 22 that is inserted into the long pipe of the T-shaped pipe to position the long pipe.

[0041] In the above technical solution, after the lifting cylinder lifts the T-connector, the positioning rod extends into the long tube of the T-connector to position the long tube, making it easier for the clamping mechanism to grip it.

[0042] Specifically, the side of the positioning mold is provided with a clamping device for pressing the short tube onto the long tube. The clamping device includes a clamping support 23 fixed on the base, a clamping cylinder 24 fixed on the clamping support, and a clamping rod 25 connected to the output end of the clamping cylinder.

[0043] In the above technical solution, the clamping device is used to further clamp the short pipe into the through hole of the long pipe.

[0044] Specifically, the clamping mechanism and the pressing assembly are mounted on both sides of the base plate via a bracket. The bracket includes side plates 26 fixed to both ends of the base plate and a fixing rod 27 fixed between the side plates. It also includes an ejection mechanism, which includes an ejection cylinder 28 and an ejection rod 29. The ejection rod passes through the clamping device to eject the welded tee pipe from the clamping device.

[0045] The ejection mechanism ejects the welded tee pipe from the clamping device and discharges it from the discharge port on the base plate.

[0046] Specifically, the top-pressing assembly includes a top-pressing cylinder 30 fixed on the side plate, a transmission plate 31 connected to the output end of the top-pressing cylinder, a top-pressing fixing plate 33 connected to the transmission plate via a connecting rod 32, and a top-pressing head 34 fixed on the top-pressing fixing plate. The transmission plate and the top-pressing fixing plate are slidably connected to the fixing rod.

[0047] The top pressure assembly is used to press the tee pipe onto the clamping device, serving as an auxiliary fixation and clamping function.

[0048] Specifically, it also includes a positioning and correction structure, which includes a positioning and correction cylinder 35 fixed on the transmission plate and a correction rod 36 on the output end of the positioning and correction cylinder. The correction rod passes through the top pressure fixing plate and the top pressure head and extends into the short pipe through hole clamped on the clamping device.

[0049] The positioning and straightening structure is mainly used to correctly connect the short pipe to the long pipe, avoiding defective products welded due to the tilting of the short pipe, and improving product quality.

[0050] Please note to all technical personnel: Although the present invention has been described according to the specific embodiments above, the inventive concept of the present invention is not limited to this invention. Any modifications that utilize the inventive concept will be included within the scope of protection of this patent.
