[0036] Please refer to Figures 1 to 7 As shown, a welding device for a motor spoke includes a frame 1, a lifting seat 2, a moving seat 3, a fixed seat 4, a first driving member 5, a welding mechanism 6 and a feeding mechanism 7, wherein,

[0037] The lifting seat 2 is liftably mounted on the frame 1. The fixed end of the first driving member 5 is mounted on the frame 1, and the movable end of the first driving member 5 is connected to the lifting seat 2. The first driving member 5 drives the lifting seat 2 to lift and lower.

[0038] The fixed seat 4 is fixed to the lifting seat 2, and a first rotary clamping member 40 is rotatably mounted on the fixed seat 4.

[0039] The moving seat 3 is movably mounted on the frame 1. A rotary driving device 30 is mounted on the moving seat 3, and a second rotary clamping member 31 is connected to the driving end of the rotary driving device 30.

[0040] A second driving member 20 is provided on the lifting seat 2. The fixed end of the second driving member 20 is mounted on the lifting seat 2, and the movable end of the second driving member 20 is connected to the moving seat 3. The second driving member 20 drives the moving seat 3 to approach or move away from the fixed seat 4 so that the first rotary clamping member 40 and the second rotary clamping member 31 clamp or release the motor housing 10. When the first rotary clamping member 40 and the second rotary clamping member 31 clamp the motor housing 10, the rotary driving device 30 is used to drive the motor housing 10 clamped by the first rotary clamping member 40 and the second rotary clamping member 31 to rotate a preset angle.

[0041] The welding mechanism 6 includes an upper electrode 60, a lower electrode 61, and a lifting drive member 62. The lower electrode 61 is fixed to the frame 1 and penetrates through the first rotary clamping member 40. A positioning groove 63 for positioning the spoke is formed in the lower electrode 61. The fixed end of the lifting drive member 62 is mounted on the frame 1, and the movable end of the lifting drive member 62 is connected to the upper electrode 60. The lifting drive member 62 drives the upper electrode 60 to descend and abut against the motor housing 10, so as to cooperate with the lower electrode 61 to heat and weld the spoke at a specified position on the motor housing 10.

[0042] The feeding mechanism 7 is used to automatically feed the spoke into the positioning groove 63 and push the spoke to a specified position.

[0043] It can be seen that by moving the moving seat 3 close to the fixed seat 4, the first rotary clamping member 40 and the second rotary clamping member 31 clamp the motor housing 10. Then, the feeding mechanism 7 conveys the spoke to a preset position. The welding mechanism 6 heats and welds the motor housing 10 and the spoke. When one spoke is welded, the lifting seat 2 ascends. After the first rotary clamping member 40 and the second rotary clamping member 31 rotate the motor housing 10 by a preset angle, the lifting seat 2 returns to its original position. The feeding mechanism 7 then conveys the next spoke to the corresponding welding position for welding. This process is repeated until the specified number of spokes are automatically welded on the motor housing 10, realizing the automated operation of welding the spokes on the motor housing 10 and greatly improving the production efficiency.

[0044] As an implementation manner, the feeding mechanism 7 includes a vibrating screen 70, a spoke flow channel 71, a pushing drive member 72, and a pushing rod 73.

The pushing drive member 72 drives the pushing rod 73 to move, so as to push the spoke to be welded in the spoke flow channel 71 into the positioning groove 63 and move it to a specified position.

[0045] It can be seen that the vibrating screen 70 conveys the spoke to a specified position through the spoke flow channel 71, and the pushing drive member 72 drives the pushing rod 73 to push the spoke into the specified position of the positioning groove 63, providing a feeding mechanism 7 with high automation and labor saving.

[0046] As an implementation manner, the feeding mechanism 7 further includes a storage magazine 74 for storing the spokes. The storage magazine 74 is vertically installed on the frame 1. The top of the storage magazine 74 is provided with a feeding end, and the bottom of the storage magazine 74 is provided with a discharging end. The feeding end of the storage magazine 74 is communicated with the discharging end of the spoke flow channel 71. The spokes to be welded conveyed by the vibrating screen 70 are stacked and enter the storage magazine 74 through the feeding end of the storage magazine 74. The discharging end of the storage magazine 74 is communicated with the feeding end of the positioning groove 63. The pushing rod 73 is arranged outside the discharging end of the storage magazine 74. The pushing driving member 72 drives the pushing rod 73 to approach the discharging end of the storage magazine 74 to push the lowermost spoke to be welded located in the storage magazine 74 into the positioning groove 63.

[0047] It can be seen that using the storage magazine 74 to store the spokes conveyed by the vibrating screen 70 and providing a preliminary positioning for the spokes to enter the positioning groove 63 provides a storage mechanism with automatic storage and easy implementation.

[0048] As an implementation manner, a positioning assembly 8 is further arranged outside the lower electrode 61. The positioning assembly 8 includes a positioning driving member 80 and a positioning block 81. The fixed end of the positioning driving member 80 is installed on the frame 1, and the movable end of the positioning driving member 80 is connected to the positioning block 81. When welding the spokes, the positioning driving member 80 drives the positioning block 81 to fix the position of the spokes in the positioning groove 63.

[0049] It can be seen that an avoidance groove for the positioning block 81 to enter is provided on the lower electrode 61. After the spokes enter the motor housing 10 through the positioning groove 63, the positioning driving member 80 drives the positioning block 81 to enter the avoidance groove to fix the position of the spokes and then perform welding, providing a positioning assembly 8 with a simple structure and easy implementation.

[0050] As an implementation manner, the first rotary clamping member 40 includes a bearing 400. The outer ring of the bearing 400 is fixedly installed on the fixed seat 4.

[0051] It can be seen that by using the method of fixing the outer ring of the bearing 400 and detachably installing the first clamping ring 401 on the inner ring of the bearing 400, the first rotary clamping member 40 and the second rotary clamping member 31 can clamp and rotate the motor housing 10 without affecting the lower electrode 61, providing a rotary clamping member with a simple structure and easy implementation.

[0052] As an implementation manner, the loading mechanism 7 further includes a moving block 75, a fixed block 76, a first linear guide rail 77 and a first slider 78. The first linear guide rail 77 is fixedly installed on the frame 1 along the pushing direction of the pushing rod 73. The pushing rod 73 is detachably installed on the moving block 75 through the fixed block 76. The moving block 75 is detachably installed on the first slider 78. The first slider 78 is slidably assembled on the first linear guide rail 77. The movable end of the pushing driving member 72 is connected to the moving block 75. The pushing driving member 72 drives the moving block 75 to move on the first linear guide rail 77 through the first slider 78, so as to push the spoke to be welded in the positioning groove 63 by the pushing rod 73 into the specified position.

[0053] It can be seen that when the pushing driving member 72 drives the pushing rod 73 to load materials, the first linear guide rail 77 and the first slider 78 are used to guide the pushing rod 73, so that the pushing rod 73 can accurately push the spoke into the positioning groove 63, and the length of the pushing rod 73 can be adjusted on the moving block 75 by loosening the fixed block 76, providing a loading mechanism 7 with adjustable pushing stroke and accurate loading.

[0054] As an implementation manner, a guiding component 9 is arranged between the lifting seat 2 and the frame 1. The guiding component 9 includes at least two second linear guide rails 90. The at least two second linear guide rails 90 are vertically fixed on the frame 1. A second slider 91 is arranged on each second linear guide rail 90. The second slider 91 is fixedly connected to the lifting seat 2.

[0055] Or at least two second linear guide rails 90 are vertically fixed on the lifting seat 2. A second slider 91 is arranged on each second linear guide rail 90. The second slider 91 is fixedly installed on the frame 1.

[0056] It can be seen that the second linear guide rail 90 and the second slider 91 are used for guiding between the lifting seat 2 and the frame 1, providing a lifting seat 2 with reliable lifting and simple structure.

[0057] As an implementation manner, the lower electrode 61 includes a base 610, a mounting seat 611, a first electrode portion 612 and a second electrode portion 613. The base 610 is fixedly installed on the frame 1. The mounting seat 611 is fixed on the base 610 and penetrates through the first rotary clamping member 40. The first electrode portion 612 and the second electrode portion 613 are detachably installed on the mounting seat 611 and penetrate through the first rotary clamping member 40. A gap is formed between the first electrode portion 612 and the second electrode portion 613 to form the positioning groove 63.

[0058] Preferably, the base 610, the mounting seat 611, the first electrode portion 612 and the second electrode portion 613 are all provided with mounting holes.

[0059] It can be seen that by adopting modular installation of the lower electrode 61, it is convenient for the disassembly, assembly and maintenance of the lower electrode 61, and the width of the positioning groove 63 can be set through installation, providing a lower electrode 61 with a simple structure and easy to implement.

[0060] As an implementation manner, a stepped surface for carrying the spokes is arranged on the first electrode portion 612 along the length direction, and a boss is arranged on the second electrode portion 613 along the length direction. The boss is located above the stepped surface and a positioning groove 63 is formed between the two.

[0061] It can be seen that by adopting the boss, when the spokes are fed into the interior of the motor housing 10 in the positioning groove 63, they can directly contact the motor housing 10, providing a lower electrode 61 with a simple structure and easy to implement.

[0062] The working principle of the above-mentioned motor spoke welding device is as follows:

[0065] S3. The pusher driving member 72 drives the pusher rod 73 to push the spokes at the discharge port of the storage magazine 74 into the positioning groove 63 and finally push them to the designated welding position inside the motor housing 10;

[0066] S4. The lifting driving member 62 drives the upper electrode 60 to descend, abutting against the designated welding position of the motor housing 10. The upper electrode 60 and the lower electrode 61 are simultaneously energized to heat the motor housing 10 and the spokes to start welding. During welding, the positioning driving member 80 drives the positioning block 81 into the positioning groove 63 to fix the spokes so as to prevent the spokes from shifting during welding;

[0067] S5. After welding is completed at this position, the first driving member 5 drives the lifting seat 2 to rise to drive the motor housing 10 and the spokes to rise, so that the spokes leave the positioning groove 63 to avoid interference during rotation;

[0068] S6. The rotation driving device 30 drives the first rotary clamping member 40 and the second rotary clamping member 31 to rotate a preset angle, and then drives the motor housing 10 to rotate a preset angle, so that the motor housing 10 rotates to the next spoke welding position;

[0069] S7. The first driving member 5 drives the lifting seat 2 to descend and reset, and repeats the welding steps of steps S3 - S4;

[0070] S8. Repeat the actions of steps S5 - S7 until the specified number of spokes are welded onto the motor housing 10.
