Description

An automated welding production line and method for motor mounts Technical Field

[0001] This invention belongs to the field of welding production line technology, specifically, it relates to an automated welding production line and method for motor mounts. Background Technology

[0002] The motor mount is a finished motor mount made by splicing and welding multiple motor mount components. During the production of the motor mount, the assembly and welding are carried out by manual production line. The assembly is done by workers using the KBK handling system to transport the motor mount components to the assembly and welding platform for manual positioning and fixing. The fixing is done by manual welding gun. After the assembly is completed, it is manually transported to the repair welding workstation for repair welding. Then it is manually transported to the manual repair welding workbench for repair welding and grinding. Finally, it is manually corrected and removed from the production line.

[0003] During the production process, the motor base is heavy, and manual handling is too strenuous. Using lifting equipment is inefficient and dangerous. Furthermore, manual teaming is inefficient, requiring repeated manual measurement of dimensions, which cannot guarantee team consistency and results in a high rework rate. The motor base has many welding positions, requiring frequent adjustments to the welding posture, leading to low manual welding efficiency and unstable welding quality. Therefore, there is an urgent need for an automated welding production line that can automatically assemble and weld motor bases. Summary of the Invention

Automatic teaming tooling platforms are provided on both sides of the transport robot's walking track, and a secondary centering platform is provided on the side of the automatic teaming tooling platform away from the transport robot's walking track.

[0010] Further optimization: There are two sets of flipping buffer platforms, and the two sets of flipping buffer platforms are set on one side of the walking track of the handling robot and close to the side of the robot's automatic welding station.

[0017] The present invention also provides an automated welding production method for motor mounts. Based on the above-mentioned automated welding production line for motor mounts, the production method is carried out according to the following steps:

[0018] Step 1: First, place the individual motor base parts to be assembled into their respective positions on the precise positioning frame of the parts, and then start the automated welding production line for the motor base.

[0019] Step 2: At the automatic assembly station for motor seats, the handling robot A picks up the motor seat components from the component loading precision positioning frame according to the process requirements and places them on the secondary alignment platform. The secondary alignment platform is used to align the motor seat components. Then, the aligned components are picked up from the secondary alignment platform and placed on the automatic assembly fixture platform. The automatic assembly fixture platform is used to position and clamp the motor seat components. Then, the assembly arc welding robot performs spot welding on the motor seat components.

[0022] Step 5: At the manual welding and grinding off-line station, workers use the KBK electric hoisting system to lift the motor seat workpiece onto the manual welding dual-axis positioner, and clamp the workpiece with a fixture. Workers then use a manual arc welding machine to perform welding and grinding operations on the motor seat. After manual processing, the motor seat is lifted by the KBK electric hoisting system to the leveling machine system for equipment alignment. After completion, workers stack the motor seats into the finished product precision positioning unloading frame.

An automated welding production method for motor mounts, based on the automated welding production line for motor mounts as described in claim 6, the production method is carried out according to the following steps: Step 1: First, the motor mount parts to be assembled are placed sequentially at the placement positions on the component mounting precision positioning frame (104), and then the automated welding production line for motor mounts is started; Step 2: At the position of the automatic assembly station (1) for motor mounts, the handling robot A (401) works to pick up the motor mount parts sequentially from the component mounting precision positioning frame (104) according to the process requirements and place them on the secondary alignment platform (103), the secondary alignment platform (103)... 3) The motor seat assembly is used for centering operations. Then, the aligned assembly is picked up from the secondary centering platform (103) and placed on the automatic assembly tooling platform (102). The automatic assembly tooling platform (102) is used to position and clamp the motor seat assembly. Then, the assembly arc welding robot (101) works to perform spot welding on the motor seat assembly. After spot welding is completed, the transport robot B (402) removes the motor seat and places it on the flip buffer table (106). The flip buffer table (106) automatically flips the motor seat to a vertical state. Step 3: At the position of the robot automatic welding station (2), the transport robot B (402) The machine will place the motor seat on the flipping buffer table (106) onto the fixture of the automatic arc welding dual-axis positioner (202). The fixture will automatically position and clamp the motor seat. The automatic arc welding dual-axis positioner (202) will drive the motor seat to rotate and change its posture. The automatic arc welding robot (201) will perform welding operations on the motor seat. After welding is completed, the transport robot C (403) will remove the welded motor seat and transport it to the manual repair welding and grinding off-line station (3). Step 4: The transport robot C (403) will place the removed motor seat on the buffer conveyor line (306). When the buffer conveyor line (306) is full, The motor seat is temporarily stored on transfer station A (203) and transfer station B (204); Step 5: At the position of the manual welding and grinding off-line station (3), the worker uses the KBK electric hoisting system (301) to hoist the motor seat workpiece to the manual welding dual-axis positioner (302) and clamps the workpiece with a clamp. The worker uses the manual arc welding machine (303) to perform welding and grinding operations on the motor seat. The motor seat that has been manually processed is hoisted to the leveling machine system (305) by the KBK electric hoisting system (301) for equipment calibration. After completion, the worker stacks the motor seat into the finished product precision positioning lower part frame (304).
