[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The embodiment of the present application solves the problem that the existing parts to be welded need to be placed one by one manually by providing an automatic material placing mechanism and a welding furnace, thereby realizing automatic feeding of the parts to be welded.

[0053] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0054] Before welding, the existing welded parts need to be placed on a conveyor belt on the furnace mouth of the welding furnace so that the welded parts can enter the welding furnace for welding.

[0055] However, the existing parts to be welded need to be placed one by one manually, so the placement efficiency is low;

[0056] The research found that Figure 1-Figure 10 As shown, by setting up an automatic material swinging mechanism, multiple parts to be welded are pushed synchronously by the automatic material swinging mechanism, which solves the problem of manual material swinging during welding of existing parts to be welded, realizes automatic feeding operation of parts to be welded, and improves overall work efficiency.

[0057] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] Example:

[0059] like Figure 1-Figure 5 As shown, an automatic material swinging mechanism comprises a support body 1, a material transfer platform 2 and a material dropping structure 3;

[0060] The blanking structure 3 is installed on the material transfer platform 2, and a hollow cavity 30 is opened on the blanking structure 3. A plurality of to-be-welded parts 31 adapted to the hollow cavity 30 are vertically stacked in the hollow cavity 30;

[0061] The material transfer platform 2 includes two symmetrically arranged L-shaped material plates, the sides of the two L-shaped material plates with notches are close to each other, and the two material plates are fixed by a connecting piece;

[0062] A support groove 20 is formed between the notches of the two L-shaped material plates, and the support groove 20 is used to support the swinging material of the multiple parts 31 to be welded;

[0063] The distance between the two L-shaped material plates forms a pushing groove 21, and the pushing groove 21 is located below the supporting groove 20 and penetrates the supporting groove 20;

[0064] The material transfer platform 2 is installed on the support body 1 and fixed to the support body 1. The support body 1 is also equipped with a positioning block 10, a slider 11 and a reciprocating structure. The slider 11 is slidably connected to the positioning block 10 through a slide groove and slides back and forth on the positioning block 10 through the reciprocating structure.

[0065] The slider 11 is provided with a plurality of swing rods 16, each of which is rotatably connected to a support 15 fixedly connected to the slider 11 via a rotating rod, and the slider 11 is provided with a plurality of micro motors corresponding to the swing rods 16, each of which is used to drive a corresponding rotating rod and control the rotation of the swing rod 16;

[0066] The distance between the bottom of the blanking structure 3 and the support groove 20 is smaller than the thickness of the two pieces to be welded 31 stacked together, and the swing rod 16 pushes one piece to be welded 31 located below the blanking structure 3 at a time;

[0067] When the material is swinging, each swing rod 16 pushes the workpiece 31 to be welded at the corresponding position in sequence, and the multiple workpieces 31 to be welded located on the material transfer platform 2 are all pushed to the next swinging position synchronously.

[0068] By setting up an automatic swinging mechanism and using it to push multiple parts to be welded 31 synchronously, the problem of manual swinging of the parts to be welded 31 during welding is solved, and the automatic feeding operation of the parts to be welded 31 is realized, thereby improving the overall work efficiency.

[0069] like Figure 1-Figure 3 As shown, the reciprocating mechanism includes a connecting rod 12, a connecting rod 2 13 and a connecting rod 3 14, wherein the connecting rod 12 is rotatably connected to the support body 1 through the rotating shaft 1, the connecting rod 2 13 is rotatably connected to an end of the connecting rod 12 away from the rotating shaft 1 through the rotating shaft 2, the connecting rod 3 14 is rotatably connected to an end of the connecting rod 2 13 away from the rotating shaft 2 through the rotating shaft 3, and the side of the connecting rod 3 14 away from the rotating shaft 3 passes through the positioning block 10 and is fixedly connected to the slider 11, and is slidably connected to the positioning block 10;

[0070] The rotating shaft 1 is driven by a driving motor 1, and the driving motor 1 is installed on the supporting body 1 and fixedly connected to the supporting body 1.

[0071] By arranging the reciprocating mechanism in the form of connecting rod 12, connecting rod 2 13 and connecting rod 3 14, driving connecting rod 12 to control connecting rod 2 13 and connecting rod 3 14 to drive the slider 11 to slide back and forth on the positioning block 10, each to-be-welded part 31 on the material transfer table 2 is gradually pushed, and the subsequent automatic feeding operation during the welding process is realized. The whole structure is simple and compact, which is convenient for the layout of the automatic swinging mechanism during use;

[0072] The reciprocating structure provides driving force for the rotating shaft 1 through the motor. Since the connecting rod 12 is rotationally connected to the support body 1 through the rotating shaft 1, the driving motor controls the rotation of the connecting rod 12, and then controls the swing of the connecting rod 2 13 rotationally connected to the connecting rod 12. During the swinging of the connecting rod 2 13, the connecting rod 2 13 drives the connecting rod 3 14 to move back and forth, and then controls the slider 11 fixedly connected to the connecting rod 3 14 to move back and forth along the slide groove in the positioning block 10, thereby realizing the reciprocating process of the slider 11.

[0073] like Figure 5 As shown, the support groove 20 is adapted to a plurality of parts 31 to be welded;

[0074] During the material swinging, the plurality of parts to be welded 31 on the material transfer platform 2 are all in contact with the groove wall of the support groove 20 .

[0075] By configuring the support groove 20 to be compatible with the workpiece 31 to be welded, the stability of the workpiece 31 to be welded when being pushed along the support groove 20 is improved, thereby improving the overall regularity of the swing material.

[0076] like Figure 5 As shown, two symmetrically arranged support blocks 22 are installed on the material transfer platform 2, each of the support blocks 22 is fixedly connected to a corresponding L-shaped material plate, and each of the support blocks 22 is provided with a screw hole 1;

[0077] The side of the blanking structure 3 is provided with screw holes 2 which correspond one to one with the screw holes;

[0078] During installation, the blanking structure 3 is fixed by bolts passing through the corresponding screw holes 1 and 2.

[0079] The blanking structure 3 and the material transfer platform 2 are installed by using the support block 22, and the bolts are installed by passing through the screw hole 1 and the screw hole 2. The whole installation method is simple and easy to operate.

[0080] like Figure 5-Figure 10 As shown, the blanking structure 3 is provided with a plurality of slots 301, and the plurality of slots 301 are all connected with the hollow cavity 30;

[0081] Two plug-in plates 32 are installed in the blanking structure 3, and each of the plug-in plates 32 is plugged into the blanking structure 3 through a corresponding slot 301;

[0082] Two overlapping blocks 23 are symmetrically arranged on the material transfer platform 2, and each overlapping block 23 is detachably connected to a corresponding L-shaped material plate;

[0083] The two overlapping blocks 23 are used to adjust the width of the supporting groove 20 and the pushing groove 21;

[0084] After plugging, the bottoms of the two plug boards 32 are flush with the bottom of the blanking structure 3 and contact with the overlap block 23 .

[0085] Specifically, each of the overlapping blocks 23 is fixedly connected to the corresponding L-shaped plate by bolts.

[0086] By providing the overlap block 23 and utilizing the overlap block 23 to adjust the width of the support groove 20 and the push groove 21 , the swinging of the to-be-welded parts 31 of different lengths can be achieved.

[0087] It should be noted that when in use, according to the length of the workpiece 31 to be welded, the insert plate 32 is inserted into the corresponding slot 301, and the corresponding overlap block 23 is selected to adjust the support groove 20 so that the support groove 20 is adapted to the workpiece 31 to be welded of corresponding length, so that the swing mechanism can be suitable for the automatic swing operation of the workpiece 31 to be welded of different lengths.

[0088] like Figure 1 As shown, a welding furnace comprises an automatic swinging mechanism and a furnace body 4, wherein the automatic swinging mechanism is fixedly connected to the furnace body 4 via a connecting plate;

[0089] A material transport platform 40 is provided on one side of the furnace body 4 close to the material swinging mechanism, and a conveyor belt 411 is installed on the material transport platform 40. The conveyor belt 411 enters the furnace opening of the furnace body 4 through a rotating roller 41.

[0090] The upper horizontal surface of the conveyor belt 411 is flush with the bottom of the workpiece 31 to be welded placed on the material transfer platform 2;

[0091] When the material is swinging, the workpiece 31 to be welded near one end of the conveyor belt 411 is transferred to the horizontal plane of the conveyor belt 411 for transportation under the push of the swing rod 16.

[0092] By arranging the automatic swinging mechanism on the furnace body 4 of the welding furnace, automatic feeding of the workpieces 31 to be welded used in the welding furnace can be achieved.

[0093] Specifically, in actual application, two baffles can be set on the transport platform 40, and the two baffles are respectively located on both sides of the conveyor belt 411 to limit the transfer of the parts 31 to be welded on the automatic feeding mechanism, and can protect the transfer of the parts 31 to be welded on the transport platform 2.

[0094] During operation, the insert plate 32 is inserted into the corresponding slot 301 according to the length of the workpiece 31 to be welded, and the length of the stacking space of the workpiece 31 to be welded in the blanking structure 3 is adjusted by using the two insert plates 32, so as to adapt to the stacking of the workpieces 31 to be welded of different lengths in the blanking structure 3;

[0095] At the same time, the matching overlap block 23 is installed on the corresponding L-shaped plate according to the length of the welded part 31, and the width of the support groove 20 between the two L-shaped plates is adjusted so that the width of the support groove 20 can match the length of the welded part 31;

[0096] After the adjustment is completed, multiple parts to be welded 31 are vertically stacked in the blanking structure 3. Under the action of gravity, multiple parts to be welded 31 are automatically blanked along the cavity wall of the hollow cavity 30. In actual application, the distance between the bottom of the blanking structure 3 and the bottom of the support groove 20 is less than the thickness of two parts to be welded 31. Therefore, only one part to be welded 31 can be completely leaked out of the support groove 20 at a time. Specifically, when setting, the distance between the bottom of the blanking structure 3 and the bottom of the support groove 20 is the thickness of one and a half parts to be welded 31, which can facilitate the blanking of one part to be welded 31 at a time.

[0097] It should be noted that when the support blocks 22 are provided, a plurality of screw holes are provided on each support block 22 along the vertical direction of the blanking structure 3 so as to adjust the distance between the bottom of the blanking structure 3 and the bottom of the support groove 20, so as to facilitate the blanking operation of the welded parts 31 with different thicknesses.

[0098] After the blanking structure 3 automatically blanks, Figure 4 As shown, in the initial state, multiple rocker arms 16 are respectively located at corresponding rocker positions and in contact with the workpiece 31 to be welded, wherein the rocker arm 16 close to the blanking structure 3 is vertical and in contact with the side of the workpiece 31 to be welded below the blanking structure 3, and then the reciprocating structure is used to drive the slider 11 to slide toward the welding furnace on the positioning block 10, and the rocker arm 16 is synchronously controlled to rotate toward one side of the furnace body 4, so as to push the workpiece 31 to be welded on the rocker position, and gradually push the workpiece 31 to be welded to the rocker position gradually close to the furnace body 4, and when the slider 11 is away from the positioning block 10 and the rocker arm 16 is located between the two rocker positions, multiple rocker arms 16 are synchronously rotated to Figure 4 In state 2, the swing rod 16 in state 2 moves to the initial swing position under the action of the reciprocating structure. At this time, the weldment 3 313 in the initial state moves to the position of the weldment 2 312, the weldment 2 312 in the initial state moves to the position of the weldment 1 311, and the weldment 1 311 in the initial state moves to the conveyor belt 411 on the furnace body 4, and enters the furnace body 4 through the furnace mouth of the furnace body 4 under the action of the conveyor belt 411 for welding;

[0099] Afterwards, as the reciprocating structure returns to its original position, the multiple rocker arms 16 are controlled to reset to their initial states, and the slider 11 slides back and forth along the positioning block 10 to move closer to or away from the furnace body 4. Combined with the rotation of the rocker arms 16, the sequential progressive feeding operation of the parts to be welded 31 is realized.

[0100] It should be noted that the operation of the conveyor belt 411, the reciprocating structure and the rotation of the multiple rocker arms 16 are all controlled by a numerical control system, and the multiple structures will not interfere with each other during operation;

[0101] When the swing rod 16 pushes the workpiece 31 to be welded which is closest to the swing position of the furnace body 4 onto the conveyor belt 411, the swing rod 16 rotates to complete the pushing process of the workpiece 31 to be welded, and the swing rod 16 never contacts the conveyor belt 411;

[0102] Weldment one 311 , weldment two 312 , and weldment three 313 are all the same parts 31 to be welded.

[0103] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0104] 1. By setting up an automatic swinging mechanism, multiple parts to be welded 31 are pushed synchronously by the automatic swinging mechanism, which solves the problem of manual swinging during welding of the existing parts to be welded 31, realizes the automatic feeding operation of the parts to be welded 31, and improves the overall work efficiency.

[0105] 2. By setting the support groove 20 in a form that is compatible with the workpiece 31 to be welded, the stability of the workpiece 31 to be welded when being pushed along the support groove 20 is improved, thereby improving the overall regularity of the swing material.

[0106] 3. By setting the overlap block 23 and using the overlap block 23 to adjust the width of the support groove 20 and the push groove 21, the swinging of the welded parts 31 of different lengths can be achieved.
