Description

Technical Field

[0001] This utility model relates to the field of welding robot base technology, and in particular to a base structure for a welding robot. Background Technology

[0002] Welding robots are key equipment in the field of industrial automation and are widely used in industries such as automobile manufacturing, shipbuilding, and heavy machinery processing. As the core component that supports the robot body and actuators, the base must have stability, durability, and adaptability to complex working conditions. However, the existing welding robot bases are open structures, and the high-temperature metal chips, welding slag, and fumes generated during the welding process fall directly into the base and onto the robot joints. Such spatter can not only jam transmission components (such as reducers and servo motor shafts) but also adhere to the surface of circuit boards or sensors, causing short circuits or signal interference.

[0003] Therefore, to address the above problems, a base structure for a welding robot is proposed. By rotating guide vanes to generate directional airflow, the spatter is directed to the magnetic attraction area to adsorb metal debris. Non-metallic dust is separated into gas and solid states through a double-layer filter frame, preventing dust from entering the robot's interior and providing protection for the welding robot. Utility Model Content

[0004] In order to overcome the problem that, during the daily use of traditional welding robots, high-temperature metal shavings, welding slag, and fumes generated during the welding process directly fall into the base and robot joints, causing short circuits or signal interference.

[0005] The technical solution of this utility model is as follows: a base structure for a welding robot, including a fixed frame, a mounting frame, a dust collection component, a drive component, and a protective component. The mounting frame is located above the fixed frame, the dust collection component is located on one side of the fixed frame, the drive component is located below the fixed frame, and the protective component is located above the fixed frame. The dust collection component includes a first connecting frame, a guide plate, a first mounting plate, a magnetic strip, a scraper, guide vanes, a dust discharge pipe, a first filter frame, a second filter frame, and a discharge pipe. A first connecting frame, a guide plate, a second filter frame, and a discharge pipe are located on one side of the fixed frame. The connecting frame has four sets of first connecting frames, located on the four sides of the fixed frame. The inner side of the first connecting frame is provided with a guide plate, and the inner side of the fixed frame is provided with a first mounting plate. The first mounting plate and the first connecting frame are slidably connected. The inner side of the first mounting plate is provided with a magnetic strip. The inner side of the first connecting frame is provided with a scraper. The inner side of the fixed frame is provided with guide vanes. The bottom of the fixed frame is provided with a dust discharge pipe. The inner side of the fixed frame is provided with a first filter frame and a second filter frame. The bottom of the first connecting frame is provided with a discharge pipe.

[0006] Preferably, a mounting frame is used for installation and connection with the welding robot. The rotating guide vanes guide the metal debris and dust generated by the welding robot during welding along the guide ramp into the first connecting frame. The metal debris is attracted by the magnetic strip. The dust is guided into the fixed frame along the filter hole structure of the first and second filter plates and discharged through the discharge pipe. When the first mounting plate is removed from the first connecting frame, as the first mounting plate slides, the scraper scrapes off the metal debris attracted by the magnetic strip along the surface of the magnetic strip and guides it along the discharge pipe. In this way, the metal debris and dust generated during welding are collected while the welding robot is performing welding operations, preventing the metal debris and dust from entering the welding robot and causing damage to the mechanical parts of the welding robot, thus providing protection for the welding robot.

[0007] Preferably, the drive assembly includes a motor and a first rotating shaft. The motor is located below the fixed frame, and the first rotating shaft is located at the output end of the motor. The first rotating shaft is connected to the guide vane via a keyway.

[0008] Preferably, the drive assembly further includes a first gear, and the first gear is disposed on the outer side of the first shaft, with the first gear and the first shaft connected by a keyway.

[0009] Preferably, the protective component includes a second gear and a second shaft. The second gear is provided on the inner side of the fixing frame and meshes with the first gear. The second shaft is provided on the inner side of the second gear and is connected to the second gear via a keyway.

[0010] Preferably, the protective assembly also includes a third gear, which is located above the mounting bracket and connected to the second shaft via a keyway.

[0011] Preferably, the protective assembly also includes a limiting ring and a connecting ring. The limiting ring is provided above the fixing frame, and the connecting ring is provided outside the limiting ring. The connecting ring and the limiting ring are rotatably connected.

[0012] Preferably, the protective assembly also includes a fourth gear and a protective frame. The fourth gear is fixedly connected above the connecting ring, and the fourth gear meshes with the third gear. The protective frame is provided on the side of the fourth gear, and multiple sets of protective frames are provided.

[0013] The beneficial effects of this utility model are:

[0014] The mounting bracket is used for connection and installation with the welding robot. The rotating guide vanes guide the metal debris and dust generated during welding along the guide ramp into the first connecting frame. Magnetic strips attract the metal debris, and the dust is guided through the filter holes of the first and second filter plates into the fixed frame. The dust is then discharged through the discharge pipe. When the first mounting plate is removed from the first connecting frame, as it slides, a scraper scrapes off the metal debris attracted by the magnetic strips and guides it back into the discharge pipe. This process collects metal debris and dust generated during welding operations, preventing them from entering the welding robot and damaging its mechanical components, thus providing protection for the welding robot.

The inner side of the fixed frame 1 is provided with a second filter frame 109. The bottom of the first connecting frame 101 is provided with a discharge pipe 110.

[0022] Please see Figure 3 and Figure 4 In this embodiment, the drive assembly includes a motor 201 and a first rotating shaft 202. The motor 201 is disposed below the fixed frame 1, and the first rotating shaft 202 is disposed at the output end of the motor 201. The first rotating shaft 202 is connected to the guide vane 106 via a keyway. The drive assembly also includes a first gear 203. The first gear 203 is disposed on the outer side of the first rotating shaft 202, and the first gear 203 is connected to the first rotating shaft 202 via a keyway. In use, the first rotating shaft 202 is rotated by starting the motor 201, and the first gear 203 is rotated by the rotation of the first rotating shaft 202.

[0023] The protective assembly includes a second gear 301 and a second rotating shaft 302. The second gear 301 is located on the inner side of the fixing frame 1 and meshes with the first gear 203. The second rotating shaft 302 is located on the inner side of the second gear 301, and the second rotating shaft 302 and the second gear 301 are connected via a keyway. The protective assembly also includes a third gear 303, located on the top of the fixing frame 1, and connected via a keyway to the second rotating shaft 302. The protective assembly further includes a limiting ring 304 and a connecting ring 305. The limiting ring 304 is located on the top of the fixing frame 1, and the connecting ring 305 is located on the outer side of the limiting ring 304. The connecting ring 305 and the limiting ring 304 are rotatably connected. The protective assembly also includes... The fourth gear 306 and the protective frame 307 are fixedly connected above the connecting ring 305. The fourth gear 306 and the third gear 303 are meshed together. The protective frame 307 is provided on the side of the fourth gear 306. There are multiple sets of protective frames 307. In use, the first gear 203 rotates to drive the second gear 301 to rotate, the second gear 301 rotates to drive the second shaft 302 to rotate, the second shaft 302 rotates to drive the third gear 303 to rotate, the third gear 303 rotates to drive the fourth gear 306 to rotate, and the fourth gear 306 rotates to drive multiple sets of protective frames 307 to rotate, thereby further preventing flying debris from entering the mechanical structure of the welding robot during welding.

[0024] During operation, the mounting frame 2 is first used to connect with the welding robot. The metal debris generated by the welding robot during welding is guided along the guide plate 102 to the first connecting frame 101 by the rotation of the guide vane 106. The metal debris is adsorbed by the magnetic strip 104. The dust is guided into the fixed frame 1 along the filter hole structure of the first filter plate and the second filter plate. The dust is discharged through the discharge pipe 110.

[0025] When the first mounting plate 103 is removed from the first connecting frame 101, as the first mounting plate 103 slides, the scraper 105 scrapes along the surface of the magnetic strip 104 to remove the metal shavings adsorbed by the magnetic strip 104, and guides them along the discharge pipe 110. This collects the metal shavings and dust generated during the welding operation of the welding robot, preventing the metal shavings and dust from entering the welding robot and causing damage to the mechanical parts of the welding robot, thus providing protection for the welding robot.

[0026] The rotation of the first gear 203 drives the rotation of the second gear 301, which in turn drives the rotation of the second shaft 302. The rotation of the second shaft 302 drives the rotation of the third gear 303, which in turn drives the rotation of the fourth gear 306. The rotation of the fourth gear 306 then drives the rotation of multiple sets of protective frames 307, thereby further preventing spatter from entering the mechanical structure of the welding robot during welding.

[0027] Through the above steps, the mounting frame 2 is used to connect with the welding robot. The guide vanes 106 rotate to guide the metal debris and dust generated by the welding robot during welding along the guide plate 102 into the first connecting frame 101. The magnetic strip 104 is used to attract the metal debris. The dust is guided into the fixing frame 1 along the filter hole structure of the first filter plate and the second filter plate. The dust is discharged through the discharge pipe 110. When the first mounting plate 103 is removed from the first connecting frame 101, as the first mounting plate 103 slides, the scraper 105 scrapes along the surface of the magnetic strip 104 to remove the metal debris attracted by the magnetic strip 104 and guides it along the discharge pipe 110. In this way, the metal debris and dust generated during welding are collected while the welding robot is performing welding operations, preventing the metal debris and dust from entering the welding robot and causing damage to the mechanical parts of the welding robot, thus providing protection for the welding robot.
