DETAILED DESCRIPTION

[0047] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0048] See also Figure 4 and Figure 5 The present invention discloses a mechanical component welding frame tool, which is used for welding processing of a mechanical component 100, and includes an assembly unit 200, a first feeding unit 300, a second feeding unit 400, a welding unit 500 and a pressing driving unit 600;

[0049] See also Figure 6 The assembly unit 200 includes a feed slide 220 that can be moved laterally and a tooling table 230 that is rotatably arranged on the feed slide 220, and the tooling table 230 is used to position and assemble the disc member 110, the rod member 120 and the pressure ring member 130 in the mechanical component 100;

[0050] See also Figure 8 , the first feeding unit 300 includes a first feeding table 310 for placing the disc member 110, a second feeding table 320 for placing the rod member 120, and a first transfer member for transferring the disc member 110 and the rod member 120 to the tooling table 230;

[0051] See also Fig. 9 , the second feeding unit 400 includes a third feeding table 410 for placing the pressing ring 130 and a second transfer member for transferring the pressing ring 130 to the tooling table 230;

[0052] See also Fig.10, the welding unit 500 includes a longitudinally movable welding gun 550 for welding the mechanical component 100 assembled on the tooling table 230;

[0053] See also Fig.11 The pressing driving unit 600 includes a second slide table 630 that can be raised and lowered, a rotating motor 650 fixed on the second slide table 630, and a rotating material pressing member 660 connected to the output end of the rotating motor 650;

[0054] Specifically, when welding the mechanical component 100, the feed slide 220 moves horizontally to the first feeding unit 300, and the disc 110 on the first feeding table 310 is first transferred to the tooling table 230 through the first transfer member, and then the rod 120 on the second feeding table 320 is transferred to the tooling table 230, so that the circular hole 123 on the rod 120 is adapted to the cylinder 112 on the disc 110, and the concave portion 124 on the plate body 121 is adapted to the convex portion 113 on the disc body 111; then the feed slide 220 moves horizontally to the second feeding unit 400, and the disc 110 on the third feeding table 410 is transferred to the tooling table 230 through the second transfer member. The pressure ring 130 is transferred to the tooling table 230, so that the pressure ring 130 passes through the cylinder 112 and fits with the plate body 121; then the second slide 630 descends, driving the rotating press piece 660 to descend synchronously until the rotating press piece 660 is aligned with the cylinder 112 and pressed against the upper end surface of the pressure ring 130; finally, the welding gun 550 moves longitudinally to the joint between the pressure ring 130 and the plate body 121, and the welding gun 550 is turned on. At the same time, the rotating press piece 660 is driven to rotate synchronously by the rotating motor 650, so as to drive the tooling table 230 and the entire mechanical component 100 to rotate circumferentially relative to the feed slide 220, thereby realizing circumferential welding of the mechanical component 100.

[0055] It is worth noting that during the welding process of the mechanical component 100, the rotating pressing piece 660 can not only drive the entire mechanical component 100 to rotate circumferentially to ensure the regularity of the annular weld, but also the rotating pressing piece 660 can tightly press the pressure ring 130, the rod 120 and the disc 110 together, thereby ensuring that the three are always tightly fitted during the welding process, preventing the mechanical component 100 from loosening after welding and affecting the welding quality.

[0056] By pressing the rotating material pressing member 660 in the driving unit 600, the pressing ring 130, the rod 120 and the disc 110 are tightly pressed together to ensure that the three are always tightly fitted during the welding process, thereby preventing the mechanical component 100 from loosening after welding, thereby effectively avoiding welding defects caused by loose components, such as cold welding and uneven welds, and significantly improving the welding quality;

[0057] The rotating press 660 can drive the entire mechanical component 100 to rotate in the circumferential direction during the welding process, so that the welding gun 550 can weld evenly and continuously along the joint between the pressure ring 130 and the plate body 121, thereby ensuring the regularity of the annular weld and further improving the welding quality, so that the welded mechanical component 100 has better structural strength and appearance quality;

[0058] During the welding process, the feed slide 220 of the assembly unit 200 can be moved laterally to the first feeding unit 300 and the second feeding unit 400, and the disc member 110, the rod member 120 and the pressure ring 130 are sequentially transferred to the tooling table 230 for positioning and assembly through the first transfer member and the second transfer member, and then the welding gun 550 of the welding unit 500 automatically welds, which reduces manual intervention, improves welding efficiency, and shortens the production cycle;

[0059] The rotating pressing piece 660 drives the mechanical component 100 to rotate circumferentially during the welding process, so that the welding gun 550 can weld continuously without frequently adjusting the welding position, further improving the welding efficiency. Compared with the traditional welding method, the welding of the annular weld can be completed more quickly.

[0060] In one embodiment, see Figure 6 The assembly unit 200 further includes a feed rail 210, the feed slide 220 is slidably mounted on the feed rail 210, and a feed drive belt 240 for driving the feed slide 220 is provided on one side of the feed rail 210;

[0061] Specifically, by driving the feed slide 220 to slide horizontally along the feed slide rail 210 through the feed drive belt 240, the lateral movement of the workbench 230 can be achieved to complete the material removal and assembly of the mechanical component 100; the feed drive belt 240 can be driven by an external motor, and the feed slide 220 is fixedly connected to the feed drive belt 240.

[0062] For further information, see Figure 7 The tooling table 230 includes an assembly disk 231 rotatably disposed on the feed slide 220 , and the assembly disk 231 is provided with a positioning block (not shown in the figure) adapted to the protrusion 113 on the disc member 110 and a positioning block 232 adapted to the round rod 122 on the rod member 120;

[0063] Specifically, the first transfer member transfers the disc member 110 on the first feeding table 310 to the assembly disk 231, so that the groove corresponding to the lower end surface of the disc member 110 and the protrusion 113 are adapted to the positioning block, thereby realizing the positioning of the disc member 110; the first transfer member then transfers the rod member 120 on the second feeding table 320 to the assembly disk 231, so that the round rod 122 of the rod member 120 is inserted into the positioning block 232, and at the same time, the cylinder 112 of the disc member 110 is inserted into the round hole 123 of the rod member 120, thereby realizing the positioning of the rod member 120.

[0064] It should be noted that the positioning block on the assembly disk 231 is adapted to the groove on the lower end surface of the disc member 110, which can accurately position the disc member 110, ensure its accurate position during the assembly process, and avoid assembly deviation; the positioning block 232 on the assembly disk 231 is adapted to the round rod 122 of the rod member 120, and at the same time, the cylinder 112 of the disc member 110 is inserted into the round hole 123 of the rod member 120, thereby realizing the accurate positioning of the rod member 120 and ensuring the assembly accuracy of the rod member 120 and the disc member 110.

[0065] In yet another embodiment, see Figure 8 , the first transfer member includes a support frame 330 located above the first feeding platform 310 and the second feeding platform 320, a guide rod 340 is horizontally fixed on the support frame 330, a first transverse slide 350 and a second transverse slide 360 ​​are slidably mounted on both sides of the guide rod 340, a first transverse cylinder 370 for driving the first transverse slide 350 is mounted at one end of the support frame 330, and a second transverse cylinder 380 for driving the second transverse slide 360 ​​is mounted at the other end of the support frame 330;

[0067] Specifically, when the tooling table 230 moves to the loading area of ​​the first feeding unit 300, the first transverse cylinder 370 drives the first transverse slide 350 to move to just above the first feeding table 310, and then the first vertical cylinder 390 drives the first clamp 3110 to move downward to pick up the disc 110 on the first feeding table 310, and then the first transverse cylinder 370 drives the first transverse slide 350 to move to just above the tooling table 230, and the first vertical cylinder 390 drives the first clamp 3110 to move downward until the disc 110 reaches the corresponding position on the tooling table 230, and the first clamp 3110 releases the disc 110, and finally the first clamp 3110 is reset;

[0068] Similarly, after the disc 110 is placed, the second horizontal cylinder 380 drives the second horizontal slide 360 ​​to move to directly above the second feeding table 320, and then the second vertical cylinder 3100 drives the second clamp 3120 to move downward to pick up the rod 120 on the second feeding table 320, and then the second horizontal cylinder 380 drives the second horizontal slide 360 ​​to move to directly above the tooling table 230, and the second vertical cylinder 3100 drives the second clamp 3120 to move downward until the rod 120 reaches the corresponding position on the tooling table 230, the second clamp 3120 releases the rod 120, and finally the second clamp 3120 is reset.

[0069] For further information, see Fig. 9 The second transfer member includes a rotary cylinder 430 disposed on one side of the third feeding table 410, the output end of the rotary cylinder 430 is connected to a rotary frame 440, and a lifting cylinder 450 is vertically installed at one end of the rotary frame 440 away from the rotary cylinder 430, and the output end of the lifting cylinder 450 is connected to a lifting platform 460, and a material taking barrel 470 for picking up the pressure ring 130 is arranged on the lifting platform 460;

[0070] Specifically, when the workbench 230 reaches the loading area of ​​the second feeding unit 400, the rotating cylinder 430 drives the rotating frame 440 to rotate until the material barrel 470 reaches directly above the third feeding table 410, and then the lifting cylinder 450 drives the lifting platform 460 to move downward until the material barrel 470 contacts the pressure ring 130 on the third feeding table 410 and picks up the pressure ring 130, and then the rotating cylinder 430 drives the rotating frame 440 to rotate toward the side of the workbench 230 until the material barrel 470 reaches directly above the workbench 230, and the lifting cylinder 450 drives the material barrel 470 to move downward again until the pressure ring 130 in the material barrel 470 reaches the corresponding position on the workbench 230, and the material barrel 470 releases the pressure ring 130 so that the pressure ring 130 is just fitted on the cylinder 112, and finally the material barrel 470 is reset.

[0071] It should be noted that the specific manner in which the material taking barrel 470 picks up and releases the pressure ring 130 is not limited. Optionally, a suction cup structure is built into the material taking barrel 470 , and the pressure ring 130 is taken and placed by utilizing the suction and air cutting of the suction cup structure.

[0073] Specifically, the material channel in the feeding rack 420 can arrange a plurality of pressure rings 130. When the pressure rings 130 in the third feeding table 410 are picked up by the material taking barrel 470, the pressure rings 130 in the material channel can be automatically filled into the third feeding table 410 along the inclined feeding rack 420 to realize automatic feeding of the third feeding table 410.

[0074] In further embodiments, see Fig.10 The welding unit 500 further includes a first mounting platform 510, a first slide rail 520 horizontally fixed on the first mounting platform 510, and a first slide 530 slidably disposed on the first slide rail 520, the welding gun 550 is rotatably mounted on the first slide 530, and a first cylinder 540 for driving the first slide 530 is installed on one side of the first mounting platform 510;

[0075] Specifically, when the mechanical component 100 on the workbench 230 is assembled, the first slide 530 is driven by the first cylinder 540 to slide horizontally along the first slide rail 520 toward one side of the workbench 230 until the welding gun 550 reaches the welding point, and the mechanical component 100 can be welded with the cooperation of the pressing drive unit 600.

[0076] It should be noted that, in this embodiment, the welding gun 550 is an automatic arc welding machine, which can adjust the angle in the vertical plane relative to the first slide 530 according to the position to be welded of the mechanical component 100, so that the head of the welding gun 550 is just adapted to the annular weld of the pressure ring 130 and the plate body 121.

[0078] Specifically, when the workbench 230 reaches directly below the rotating press 660, the second slide 630 is driven downward along the second slide rail 620 by the second cylinder 640, thereby driving the rotating press 660 to move downward until the pressure ring 130 is tightened. Subsequently, the rotating press 660 is driven to rotate circumferentially by the rotating motor 650, thereby driving the mechanical component 100 to rotate as a whole, and with the cooperation of the welding gun 550, the circumferential welding processing of the mechanical component 100 is realized.

[0081] Specifically, in the initial state, the airbag 664 in the L-shaped cavity 663 extends out from the bottom opening of the L-shaped cavity 663; when the turntable 661 moves downward, the cylinder 112 is just inserted into the blind hole 662, and as the height of the turntable 661 continues to decrease, the end of the airbag 664 extending downward contacts the upper end surface of the pressure ring 130 and presses the pressure ring 130 vertically downward, and at the same time, the lower end of the airbag 664 gradually retracts into the L-shaped cavity 663, driving the telescopic column 665 and the spring 666 to be compressed synchronously, so that the airbag 66 The upper end of the cylinder 112 gradually extends radially into the blind hole 662 to radially squeeze the outer circumference of the cylinder 112; in this way, the entire mechanical component 100 is fixed by the rotating pressing piece 660 in both vertical and radial directions, which can effectively improve the fixing effect of the mechanical component 100, thereby ensuring that the mechanical component 100 always rotates synchronously with the rotating pressing piece 660, avoiding the mechanical component 100 from slipping, deflecting, and misaligning with the rotating pressing piece 660 during the welding process, thereby improving the welding process quality.
