[0039] Working principle:

[0040] A sleeve feeding device 14 is arranged on the upstream side of the loading robot 6, and an end cover feeding device 15 is arranged between the sleeve feeding device 14 and the loading robot 6; the reduction motor 3 is started to drive the turntable 2 to rotate by means of its output shaft until the support shaft 41 in one of the support seats 4 moves to a position that cooperates with the discharge port of the sleeve feeding device 14, and then the sleeve feeding device 14 will automatically place the sleeve in a vertical state in the positioning hole located at the center of the upper end of the support shaft 41; the reduction motor 3 is started again to drive the turntable 2 to rotate in the same way and then rotate the sleeve to the position of the end cover feeding device 15; the end cover feeding device 15 will deliver the end covers for assembly and welding to its discharge port in sequence, and the above-mentioned structure and principle are all prior arts.

[0041] The telescopic end of the first moving cylinder 63 is driven to retract inward or extend outward to drive the second lifting plate 64, the third lifting cylinder 65 and the first pneumatic finger 66 to move toward the discharge port of the end cap feeding device 15 with the help of the first moving plate 62, until the two clamping claws of the first pneumatic finger 66 are moved to the upper part of the end cap located in the discharge port of the end cap feeding device 15, and then the telescopic end of the third lifting cylinder 65 is driven to extend outward to drive the first pneumatic finger 66 to move downward with the help of the second lifting plate 64, and at the same time, the two clamping claws of the first pneumatic finger 66 are driven to separate from each other until the first pneumatic finger 66 is The two jaws of the pneumatic finger 66 are respectively located on both sides of the end cover, and then the two jaws of the first pneumatic finger 66 are driven to move closer to each other to clamp the end cover, and then the third lifting cylinder 65 and the first moving cylinder 63 are operated in reverse in the same way to move the end cover to the top of the sleeve; finally, the first moving cylinder 63, the third lifting cylinder 65 and the first pneumatic finger 66 are operated in the same way to lower the end cover to the upper end of the support shaft 41 with the sleeve, and the opening of the end cover is buckled downward on the outside of the support ring 411, and the upper end of the sleeve is inserted into the structural hole located at the center of the bottom of the end cover.

[0042] Next, the reduction motor 3 is started again to drive the assembled sleeve and end cover to move to the position of the welding assembly 7 in the same way. At this time, the driving head 104 in a rotation mechanism 10 located below the welding assembly 7 is located directly below the support seat 4 equipped with the sleeve and end cover, and the welding end of the welder 73 is located above the annular joint between the sleeve and the end cover; the telescopic end of the electric lifter 72 is driven to extend outward to drive the welder 73 to move downward until the welding end of the welder 73 contacts the annular joint between the sleeve and the end cover. After the welder 73 is started to work, its welding end The annular joint can be welded; at the same time, it is necessary to first drive the telescopic end of the first lifting cylinder 102 in the rotation mechanism 10 to extend outward to drive the rotation motor 103 to move upward until the top of the driving head 104 is concentrically pressed against the end of the driven wheel 42 in the support seat 4, and then start the rotation motor 103 to rotate its rotating shaft, and then use the friction between the driving head 104 and the driven wheel 42 to drive the driven wheel 42 to rotate, thereby driving the sleeve and the end cover to rotate with the help of the support shaft 41, and then the welding end of the welder 73 automatically performs circumferential welding on each position of the annular joint.

[0043] After welding is completed, first shut down the self-rotating motor 103 and drive the telescopic end of the electric lifter 72 to retract inward to drive the welder 73 to move upward, then start the reduction motor 3 to drive the welded sleeve and end cover to move to the position of the correction component 11, and then drive the telescopic end of the correction cylinder 112 to retract inward to drive the pressure plate 113 to move downward, and then make the correction sleeve 115 downwardly sleeved on the outside of the sleeve; then operate a self-rotating mechanism 10 located below the correction component 11 in the same way to drive the welded sleeve and end cover to rotate, so as to automatically correct the verticality of the sleeve with the help of the correction sleeve 115.

[0044] After the calibration is completed, the self-rotating motor 103 is first turned off and the reduction motor 3 is started to drive the calibrated shaft sleeve and end cover to move to the position of the oiling assembly 12. When the upper end of the shaft sleeve passes under the oil storage sleeve 123 in the oiling assembly 12, the upper end of the shaft sleeve will contact the lower outer wall of the oil storage sleeve 123 and rely on the rotational connection relationship between the rotating shaft 122 and the seat frame 121 to drive the oil storage sleeve 123 to rotate a certain angle, thereby allowing the lubricating oil in the oil storage sleeve 123 to be smeared on the upper end of the shaft sleeve, and in the same way, a self-rotating mechanism 10 located below the oiling assembly 12 is operated to drive the shaft sleeve to rotate, so that the lubricating oil is evenly applied.

[0045] After the oiling is completed, the self-rotating motor 103 is first turned off and the reduction motor 3 is started to drive the oiled sleeve and the end cover to move to the position of the detection component 13, and then the telescopic end of the second lifting cylinder 132 is driven to extend outward to drive the micro switch 134 and the ejector pin 135 to move downward with the help of the first lifting plate 133, and the self-rotating mechanism 10 located below the detection component 13 is operated in the same way to drive the sleeve to rotate, so as to comprehensively detect the welding position of the sleeve; when the lower end of the ejector pin 135 contacts the upper end of the sleeve, the ejector pin 135 will move upward, and then the upper end of the ejector pin 135 will press the moving contact of the micro switch 134 to trigger the micro switch 134, thereby confirming that the sleeve has been welded; if the lower end of the ejector pin 135 cannot detect the sleeve, it means that the sleeve is missing or crooked.

[0046] After the detection is completed, the rotation motor 103 is turned off first and the reduction motor 3 is started to drive the oiled sleeve and the end cover to move to the position of the sorting robot 8. If the micro switch 134 is not triggered, it means that the sleeve welding is unqualified. After that, the telescopic end of the third moving cylinder 83 will automatically extend outward or retract inward to drive the third lifting plate 84, the fourth lifting cylinder 85 and the second pneumatic finger 86 to move toward the direction of the sleeve with the help of the third moving plate 82, and then automatically drive the telescopic end of the fourth lifting cylinder 85 to extend outward to use the third moving plate 82 to move the third lifting plate 84, the fourth lifting cylinder 85 and the second pneumatic finger 86. The third lifting plate 84 drives the second pneumatic finger 86 to move downward, and at the same time drives the two jaws of the second pneumatic finger 86 to separate from each other until the two jaws of the second pneumatic finger 86 are respectively located on both sides of the end cover, and then drives the two jaws of the second pneumatic finger 86 to move closer to each other to clamp the end cover, and then operates the third moving cylinder 83 and the fourth lifting cylinder 85 in the same way to move the end cover to the top of the receiving box 87, and drives the two jaws of the second pneumatic finger 86 to separate from each other so that the end cover that fails the welding will automatically fall into the receiving box 87.

[0047] If the end cover is qualified after being inspected by the inspection component 13, the reduction motor 3 is started to move the inspected sleeve and end cover directly to the position of the unloading manipulator 9, and then the telescopic end of the fifth lifting cylinder 93 is driven to drive the rotating cylinder 94 and the two third pneumatic fingers 95 to move downward with the help of the fourth lifting plate 92, and at the same time, the rotating end of the rotating cylinder 94 is driven to rotate 180 degrees so that one of the third pneumatic fingers 95 is located above the sleeve and the end cover, and the third pneumatic finger 95 is continued to be driven downward with the help of the fifth lifting cylinder 93 and the two clamping claws of the third pneumatic finger 95 located above the sleeve and the end cover are driven to separate from each other until the two clamping claws of the above-mentioned third pneumatic finger 95 are respectively located on both sides of the end cover, and finally the two clamping claws of the above-mentioned third pneumatic finger 95 are driven to move closer to each other to clamp the end cover, and then the telescopic end of the fifth lifting cylinder 93 is driven inward to drive the end cover to move upward, and then the rotating end of the rotating cylinder 94 is driven to rotate 180 degrees upward, and then the welded sleeve and end cover are automatically moved to the outside to realize automatic unloading.

[0048] The utility model can realize automatic loading, positioning, welding, correction, oiling and unloading of the end cover without manual work, and all the working procedures are concentrated in the same equipment, thereby greatly improving work efficiency and reducing labor costs; in addition, the assembly welding quality of the end cover can also be automatically inspected, thereby effectively simplifying the processing process to achieve the effect of saving time and labor.
