Description

Technical Field

[0001] The invention relates to the technical field of metal pipe welding, and mainly to a metal pipe assembly welding robot. Background Art

[0002] Metal pipe fittings are usually made of metal, such as carbon steel, stainless steel, copper, etc. When connecting these pipe fittings to adjacent pipes, welding is often used for connection, because welding is a method of connecting metals by heating and melting the metal and then letting it cool, so that a dense connection can be formed between pipes, which can withstand large pressure and temperature changes, thereby ensuring the reliability and safety of the pipeline. It is widely used in pipeline installation and connection in the industrial field;

[0003] In the welding process of metal pipe fittings, it is usually necessary to use a clamp to accurately butt the two pipe fittings together before welding. However, the two pipe fittings need to be clamped using two clamps, so multiple drive devices are required, which not only increases the manufacturing cost of the equipment, but also makes it difficult to accurately butt the two pipes, which may lead to a decrease in welding quality. Therefore, it is necessary to design a metal pipe assembly welding robot to solve the above problems. Summary of the invention

[0007] The top of the gear is meshed with a second rack, and one side of the top of the second rack is connected to an L-shaped rod;

[0008] One side of the rotating cylinder is connected to a pressing mechanism, which includes a fixed cylinder connected to one side of the rotating cylinder, a first spring connected to the top of the fixed cylinder, a buffer assembly connected to the bottom of the first spring and a pressure plate connected to the bottom of the buffer assembly, and the buffer assembly cooperates with the L-shaped rod.

[0009] In the present invention, the first spring facilitates the resetting of the buffer assembly and the pressure plate, and the moving assembly facilitates the movement of the rotating cylinder and the gear. Since the gear is meshed with the second rack and the first rack, and the first rack is fixed, the gear rotates during the movement, thereby moving the second rack and further moving the L-shaped rod, thereby facilitating the L-shaped rod to squeeze the buffer assembly down.

[0010] Furthermore, the moving assembly includes a first motor connected to the top of the base, a one-way screw connected to the driving end of the first motor and a support plate connected to one side of the one-way screw, and one side of the top of the support plate is rotatably connected to a rotating cylinder.

[0015] In the present invention, the rotation of the bidirectional screw rod facilitates the two fixing seats and the clamping plate to move in opposite directions, so as to facilitate clamping the metal pipe, and the fixing seat can abut against one end of the metal pipe.

[0016] Furthermore, the buffer assembly includes a sliding rod slidably connected to the inner wall of the fixed tube, a second spring connected to the bottom groove of the sliding rod and a buffer rod connected to the bottom of the second spring, and the bottom of the buffer rod is connected to a pressure plate.

[0024] A T-shaped slider is fixed at the bottom of the first rack, and the T-shaped slider is slidably connected to the slot body of the first T-shaped slot.

[0026] Furthermore, a second T-shaped sliding groove is provided on one side of the fixing block;

[0027] An I-shaped sliding block is fixed to one side of the clamping plate at the bottom, and the I-shaped sliding block is slidably connected to the groove body of the second T-shaped sliding groove.

[0028] In the present invention, the I-shaped sliding block cooperates with the second T-shaped sliding groove to improve the supporting capacity and stability of the clamping plate.

[0029] Furthermore, the clamping plate and the pressure plate are both arc-shaped plates, and the length of the clamping plate at the bottom is greater than that of the clamping plate at the top.
