Description

Technical Field

[0001] This utility model relates to the field of welding technology, and more specifically, to a robotic internal hole surfacing welding workstation. Background Technology

[0002] A coal mining machine is a specialized piece of equipment for mining coal, and the drive arm is an irreplaceable and important part of the coal mining machine. During the coal mining process, the drive arm works continuously, which causes it to wear out severely. However, the drive arm is complex to manufacture and expensive. Therefore, when the drive arm is worn to a certain extent and cannot be used, it needs to be welded and repaired before being installed into the overall coal mining machine.

[0003] Defects and shortcomings of existing technology:

[0004] Currently, the repair of the drive arm is carried out by welding repair using a special machine, which requires manual handling of the equipment and replacement of welding torch heads, among other complex procedures. At the same time, the welding repair by the special machine is relatively slow and inefficient, so manual welding is also required. The special machine that is purchased is an imported machine, which is very expensive, has a long cycle, and is difficult to purchase spare parts.

[0005] Furthermore, the electric arcs, sparks, and fumes produced during manual welding can cause harm to the human body. The large size of the drive arm and the high welding requirements, coupled with the complexity of welding manufacturing processes, labor intensity, product quality, and batch production demands, make the automation and mechanization of welding processes extremely urgent. At the same time, production planning is difficult to control, production costs are high, and production efficiency is low, making the replacement of dedicated machines and manual welding with automated robotic welding an inevitable trend. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a robotic internal hole overlay welding workstation to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a robotic internal hole surfacing welding workstation. The welding workstation includes a three-axis slide system, a dust removal system, a welding power supply, and a system integrated control cabinet. The main components of the three-axis slide system include an inverted ground rail, a ground rail slide, a lifting column, a column slide, a lifting crossbeam, and a crossbeam slide. A ground rail slide is installed on the inverted ground rail. A lifting column is fixedly installed vertically above the ground rail slide by bolts. A column slide is installed on one side of the lifting column. A lifting crossbeam is installed horizontally on one side of the column slide. A crossbeam slide is fixedly installed at the telescopic end of the lifting crossbeam. A dust removal system is installed on the crossbeam slide. A welding power supply and a system integrated control cabinet are installed on one side of the lifting column. A workpiece for processing is placed on one side of the inverted ground rail.

[0008] As a further improvement to the technical solution of this utility model, the dust removal system mainly consists of a dust removal host, a slide trolley, a dust removal hood, and a curtain. When the equipment is welding, the dust removal system can collect the welding fumes generated during welding into the filter screen of the dust removal host for easy manual collection.

[0009] As a further improvement to the technical solution of this utility model, the welding power source is used to supply power to the equipment, and the system integrated control cabinet is used to regulate the whole system.

[0010] As a further improvement to the technical solution of this utility model, the three axes in the three-axis slide system are the external axes of the robot, which can be used in conjunction with the welding robot. The robot is upside down on the crossbeam slide of the three-axis slide system and can move in three directions: the horizontal direction of the ground rail axis, the vertical direction of the column axis, and the horizontal direction of the crossbeam axis, thus satisfying the three-axis movement of the robot.

[0011] As a further improvement to the technical solution of this utility model, the ground rail slide moves axially on the inverted ground rail, thereby completing the lateral movement of the lifting column.

[0012] As a further improvement to the technical solution of this utility model, the column slide moves up and down along the upper axis of the lifting column; the lifting beam is fixed on the column slide, and the beam slide moves along the beam axis.

[0013] As a further improvement to the technical solution of this utility model, the robot is a small intelligent handling robot with built-in cable, which has a gear drive mechanism, can handle loads with high rotational inertia, and can achieve a slim built-in cable arm.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention improves upon previous structural designs by incorporating a multi-axis welding robot. The robot boasts a short response time and rapid movements. During welding, it only requires the provided welding parameters and trajectory to repeat the actions. Welding parameters such as welding current, voltage, welding speed, and welding wire length significantly influence the welding result. With robotic welding, the welding parameters for each weld seam are constant, minimizing factors affecting weld quality and reducing the skill requirements for operator control, thus ensuring product quality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1 The robotic internal hole surfacing welding workstation shown primarily utilizes one FANUC robot (three-axis inverted), a three-axis slide system, a dust removal system 7, a welding power supply 8, and a system integration control cabinet 9. The three-axis slide system includes an inverted ground rail 1, a ground rail slide 2, a lifting column 3, a column slide 4, a lifting beam 5, and a beam slide 6. The inverted ground rail 1 is fixed to the ground, and the ground rail slide 2 moves axially along the ground rail. The lifting column 3 is fixed to the ground rail slide 2, and the column slide 4 moves up and down along the column axis. The lifting beam 5 is fixed to the lifting slide, and the beam slide 6 moves along the beam axis.

[0020] The robot is suspended upside down on the crossbeam slide 6 and can move in three directions: horizontal along the ground rail axis, vertical along the column axis, and horizontal along the crossbeam axis, thus satisfying the robot's three-axis movement.

[0021] The welding power source adopts a patented droplet necking detection and control system, resulting in a gentle arc and extremely low spatter. The pulsed low spatter produces aesthetically pleasing welds with a shorter arc and strong anti-interference capabilities, making it suitable for robot-controlled arc tracking. It features rapid arc initiation, crisp arc termination, clear fish-scale pattern, and precise control over the appearance, making it suitable for large gap and all-position welding.

[0022] The dust removal system 7 includes a dust removal host, a slide trolley, a dust removal hood, and a curtain. When the equipment is welding, the dust removal system can collect the welding fumes generated during welding into the filter screen of the dust removal host for easy manual collection.

[0023] This robot is a small, intelligent handling robot with built-in cables. It features a gear-driven mechanism, capable of handling loads with high rotational inertia, and boasts a slim, built-in cable arm. The increased hollow diameter of both the rotating and wrist axes allows for the installation of wiring and conduits behind the tool control box within the hollow of the rotating shaft. Various wiring and conduits for controlling the robotic arm can be located within the arm itself. Simultaneously, the tool box can be compactly stored behind the arm, enhancing its rigidity and enabling vibration-free positioning even after high-speed non-operational movements. The high-strength arm and cutting-edge servo control technology effectively improve the movement speed and acceleration / deceleration performance of each axis. Operation time is reduced by more than 15%, achieving the highest production capacity in the industry. A brake is installed on the motor drive shaft, operating on a closed-circuit principle, automatically engaging in the event of power failure to prevent dangerous movements.

[0024] The overall operation steps are as follows:

[0025] Place workpiece 10 in the designated position, and manually input the workpiece parameters on the system integration control cabinet 9; the robot automatically locates the position and plans the path; when the robot is welding, it automatically avoids the oil passages inside the hole;

[0026] The robotic gun head can rotate infinitely, which is suitable for spiral welding.

[0027] The final welding result exceeded the customer's requirements, effectively improving the overall welding efficiency.

[0028] The overall operation process is based on existing technology, and this application does not improve the operation method.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
