Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof motor assembly welding, in particular to a fixed and flexible dual-purpose portable clamping mechanism for a welding robot. Background Art

[0002] In the field of motor manufacturing, with the introduction of welding robots, automated welding in motor manufacturing has been realized, effectively improving the weld quality and appearance quality of motor components. During the use of welding robots, cylinders beyond the set range cannot be used due to limited clamping of welding robots, reducing the utilization rate of robots. In the field of motor manufacturing welding, when using welding robots to weld the base cylinder, how to achieve universal clamping when welding cylinders with smaller or larger diameters is a difficulty in robot welding. Summary of the invention

[0003] In view of this, it is necessary to provide a fixed and flexible dual-purpose portable clamping mechanism for a welding robot.

[0004] A fixed and flexible portable clamping mechanism for a welding robot comprises a spindle chuck, a Z-shaped clamping claw and a supporting assembly. When a cylindrical assembly with a diameter in the range of 300 mm to 470 mm needs to be welded, the Z-shaped clamping claw is fixedly mounted on the spindle chuck. When a cylindrical assembly with a diameter greater than or equal to 470 mm and less than or equal to 800 mm needs to be welded, the supporting assembly is fixedly mounted on the spindle chuck. The spindle chuck is used to be assembled with a welding robot.

[0005] Preferably, the support assembly includes a support frame and a support column, the support column is mounted on the spindle chuck, and the support frame and the support column are fixedly mounted.

[0006] Preferably, a notch is provided at the upper end of the Z-shaped clamping claw, and the design of the notch facilitates the truncated cone clamping of the spindle chuck.

[0007] Preferably, a mounting groove is provided on the support frame, and the mounting groove is used to install a scale to facilitate verticality of the welding cylinder.

[0008] The mandrel chuck matched with the welding robot of the utility model can clamp cylinders with a diameter range of 380mm-470mm. In order to broaden the welding size range of the welding robot, the matching mandrel chuck is surveyed and mapped on site, and a Z-shaped clamping claw is designed. For cylindrical welded parts with a diameter of ≥470mm and ≤800mm, a support column and a support frame are designed. The welding robot cooperates with the Z-shaped clamping claw to reduce the robot on the basis of the original minimum positioning diameter. The currently adjustable minimum diameter is 300mm. The welding robot cooperates with the support column and the support frame to further increase the robot on the basis of the original maximum positioning diameter, so that the robot support frame can be adjusted to a maximum diameter of 800mm. The tooling fixture does not need to be frequently disassembled, and only needs to automatically adjust the expansion and contraction of the diameter direction of the Z-shaped clamping claw to weld cylindrical welded parts of different diameters. Therefore, all welding structural parts that are not limited by the welding gun angle can be welded by welding robots. In actual production, tracking experiments were conducted on the welding process of the DSB-55Q base with heat dissipation ribs using the robot in conjunction with the Z-shaped claws, and tracking experiments were conducted on the welding process of the YBSD-700 / 350-4 / 8G base using the robot in conjunction with the support column and support frame. The results show that the device can cooperate with the welding robot to achieve convenient disassembly and stable welding. In this way, the use of the utility model makes the welding process of the motor cylinder assembly simple and easy to learn. At the same time, the use of robot welding reduces the intensity of manual labor, the quality of the weld is stable and reliable, and the work efficiency is high, more efficient and faster. The use of the utility model realizes automated welding in motor manufacturing and effectively improves the weld quality and weld appearance quality of the motor assembly.

[0012] In order to make the technical solution of the present utility model easier to understand, the technical solution of the present utility model is now clearly and completely described in the form of specific embodiments in combination with the accompanying drawings.

[0013] Please also see Figure 1 and Figure 2The fixed and movable dual-purpose portable clamping mechanism for the welding robot includes a mandrel chuck 1, a Z-shaped claw 2 and a support assembly. When it is necessary to weld a cylindrical assembly with a diameter within the range of 300mm-470mm, the Z-shaped claw 2 is fixedly mounted on the mandrel chuck 1. When it is necessary to weld a cylindrical assembly with a diameter greater than or equal to 470mm and less than or equal to 800mm, the support assembly is fixedly mounted on the mandrel chuck 1. The mandrel chuck 1 is used to be assembled with the welding robot. The support assembly includes a support frame 3 and a support column 4. The support column 4 is mounted on the mandrel chuck 1, and the support frame 3 and the support column 4 are fixedly mounted. Bolt a is used to fix the support column 4 on the mandrel chuck 1. A notch b is provided at the upper end of the Z-shaped claw 2. The design of the notch b facilitates the truncated table clamping of the mandrel chuck 1. An installation slot c is provided on the support frame. Installation c is used to install a scale to facilitate the verticality of the welding cylinder.

[0014] The mandrel chuck 1 of the utility model matched with the welding robot can clamp the cylinder within the range of 380mm-470mm in diameter. In order to broaden the welding size range of the welding robot, the matching mandrel chuck 1 is surveyed and mapped on site, and a Z-shaped clamping claw 2 is designed. For the cylindrical assembly weldment with a diameter of ≥470mm and ≤800mm, a support column 4 and a support frame 3 are designed. The welding robot cooperates with the Z-shaped clamping claw 2 to reduce the robot on the basis of the original minimum positioning diameter. The currently adjustable minimum diameter is 300mm. The welding robot cooperates with the support column 4 and the support frame 3 to further increase the robot on the basis of the original maximum positioning diameter, so that the robot support frame 3 can be adjusted to a maximum diameter of 800mm. The tooling fixture does not need to be frequently disassembled, and only needs to automatically adjust the expansion and contraction of the diameter direction of the Z-shaped clamping claw 2 to weld the cylindrical assembly weldment of different diameters. Therefore, all welding structural parts that are not limited by the welding gun angle can be welded by the welding robot. In actual production, the use of the robot in conjunction with the Z-shaped claw 2 was used to track the welding process of the DSB-55Q base with heat dissipation ribs. The use of the robot in conjunction with the support column 4 and the support frame 3 was used to track the welding process of the YBSD-700 / 350-4 / 8G base. The results show that the device can cooperate with the welding robot to achieve convenient disassembly and stable welding. In this way, the use of the utility model makes the welding process of the motor cylinder assembly simple and easy to learn. At the same time, the use of robot welding reduces the intensity of manual labor, the quality of the weld is stable and reliable, and the work efficiency is high, more efficient and faster. The use of the utility model realizes the automated welding of motor manufacturing and effectively improves the weld quality and weld appearance quality of the motor assembly.
