DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Based on the problem that it is difficult to ensure the thoroughness of rust removal on the inner wall of the round tube in the existing technology, please refer to Figure 1-Figure 4 The utility model provides a laser rust removal device for the inner wall of a round tube, which realizes continuous 360° circumferential rust removal inside the round tube to ensure thorough rust removal. The device as a whole consists of a laser carrier 1, a discharge rack 2 arranged at the rear side of the laser carrier 1, and a laser tube cutting machine 3 arranged at the rear side of the discharge rack 2 for clamping the round tube and completing the rust removal part cutting operation on the round tube.

[0025] The laser carrier 1 includes a fixed base 101 arranged on the front side of the unloading rack 2, and a gear guide rail A102 is installed on the top of the fixed base 101. The electric base A103 installed on the gear guide rail A102 through tooth groove engagement is composed of a bottom substrate, a servo motor, and a gear structure meshing with the gear guide rail A102. The servo motor is used to control the gear structure to rotate in a set direction, so that the electric base A103 can be controlled to drive the upper structure to move forward or backward along the path of the gear guide rail A102. A rust removal laser gun 104 extending above the unloading rack 2 is installed on the back of the electric base A103. The laser pipe cutting machine 3 includes a pipe cutting machine carrier 301, and a round pipe clamp 302 is installed on the pipe cutting machine carrier 301 for clamping the round pipe and cooperating with the rust removal laser gun 104 to remove rust on the inner wall of the round pipe in the circumferential direction, and the center of the round pipe clamp 302 and the center of the rust removal laser gun 104 are on the same axis. In actual application, the round tube to be derusted is stably clamped by the round tube clamp 302, and one end of the round tube extends from the back to the front out of the range of the laser tube cutting machine 3 and reaches the upper range of the unloading rack 2, and then the electric base A103 is used to drive the rust removal laser gun 104 to move at a uniform speed from front to back, so that the rust removal laser gun 104 enters the set position inside the round tube. At this time, the rust removal laser gun 104 is started according to the set program and the rotation function of the round tube clamp 302 is applied. The rust removal laser gun 104 uses a similar laser rust removal principle in the prior art to remove rust from the inner wall of the round tube, and at the same time cooperates with the round tube clamp 302 to drive the round tube to rotate 360° at a uniform speed, so as to achieve circumferential rust removal of the inner wall of the round tube. In addition, it is synchronously cooperated with the electric base A103 to drive it to control the rust removal laser gun 104 to move from back to front according to the set program and interval time, thereby achieving continuous circumferential rust removal of the inner wall of the round tube.

[0026] like Figure 1-Figure 2As shown, a gear guide rail B303 is installed on the top of the pipe cutting machine carrier 301, and laser cutting structures 304 are installed on both sides of the front end of the pipe cutting machine carrier 301. The round tube clamp 302 includes an electric base B3021 that engages with the gear guide rail B303 through teeth and grooves, and a positioning structure is installed on the top of the electric base B3021. A four-jaw chuck 3022 for stably clamping the round tube is sleeved on the positioning structure, and a stepper motor 3023 is installed on the top of the electric base B3021. A gear ring 3024 is fixedly sleeved on the outer surface of the four-jaw chuck 3022, and a transmission structure 3025 that engages with the gear ring 3024 through teeth and grooves is installed at the output end of the stepper motor 3023. After the rust removal is completed within the set length range of the round tube, the electric base B3021 with the same structure as the electric base A103 is operated to control it to drive the upper four-claw chuck 3022, the stepper motor 3023, the transmission structure 3025 and the clamped round tube to move from back to front, and adjust the boundary between the rust-removed and unrusted parts of the round tube to the range of the laser cutting structure 304, and then use the laser cutting structure 304 to cut off the rust-removed part of the inner wall of the round tube. When using the round tube clamp 302, the four-claw chuck 3022 is used to clamp the round tube, and then the stepper motor 3023 is used to control the transmission structure 3025 and the gear ring 3024 to rotate at a constant speed, thereby driving the four-claw chuck 3022 to rotate along the inside of the positioning structure, so as to cooperate with the rust removal laser gun 104 to achieve the purpose of circumferential rust removal of the inner wall of the round tube.

[0027] like Figure 1 and Figure 4 As shown, a dust collector 4 is provided on one side of the laser carrier 1, and a conduit 401 is connected between the input end of the dust collector 4 and the electric base A103. The electric base A103 is composed of a driving base and a frame structure installed on the top of the driving base, and the frame structure is interconnected with the rust removal laser gun 104 and the conduit 401. The rust removal laser gun 104 includes a gun barrel and a laser gun head, wherein the front end of the gun barrel is inserted into the frame structure and is interconnected with the frame structure. Since the rear end of the round tube is clamped on the four-claw chuck 3022, its rear end opening is in a blocked state, so the smoke and dust generated during the laser rust removal process can only drift forward along the inner wall of the round tube to the inside of the frame structure, and under the suction generated by the dust collector 4 in cooperation, the smoke and dust generated by the laser gun head during the laser rust removal operation on the inner wall of the round tube is quickly sucked away along the gun barrel, the frame structure and the conduit 401, thereby achieving the purpose of timely cleaning of the smoke and dust.

[0028] like Figure 1 and Figure 3As shown, a chuck fixture 105 for clamping the rust removal laser gun 104 and allowing it to move forward and backward is installed on the rear side of the top surface of the fixed base 101, and the center point of the chuck fixture 105 is on the same axis as the center point of the four-claw chuck 3022. The chuck fixture 105 is used to increase the balance of the barrel in the rust removal laser gun 104, and because its structure fits the barrel and is a rotatable cylindrical structure, it does not hinder the rust removal laser gun 104 from moving forward and backward relative to the fixed base 101. A plurality of pipe support frames 201 arranged front and back are installed on the unloading rack 2. The pipe support frame 201 is composed of a hydraulic cylinder installed inside the unloading rack 2 and a bracket connected to the free end of the hydraulic cylinder. The unloading rack 2 is used to support the front end of the round pipe clamped by the four-claw chuck 3022, so as to maintain the balance of the round pipe.
