Description

TECHNICAL FIELD

[0001] The utility model relates to the field of welding, in particular to a welding mechanism and welding equipment. BACKGROUND

[0002] In the production of the barrel body of the aging red wine, the barrel body is usually combined and welded by the upper half barrel and the lower half barrel, and a belt-shaped barrel hoop is arranged around the joint of the upper half barrel and the lower half barrel, and a flange seat is arranged at the joint of the belt-shaped barrel hoop, and the flange seat has an inner hole for installing a wine spear for tapping wine. Since the inner hole of the flange seat is usually very small, generally 47mm, it is difficult for a worker to hold a welding gun to weld and seal the joint between the flange seat and the inner wall of the barrel, and it is also difficult to observe the welding. If a robot is used to hold a welding gun to weld, the same problem exists, and welding cannot be performed. Therefore, the prior art usually only performs external welding and sealing, which affects the overall sealing effect of the barrel. SUMMARY

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a welding mechanism which can solve the problem of welding the internal weld joint formed by the first and second objects to be welded when the inner hole of the welding object of the first object to be welded is a small hole. The utility model also provides a welding equipment.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A welding mechanism comprises a welding gun and a support connecting piece, the welding gun has a welding head, the support connecting piece comprises a first support connecting section and a second support connecting section, the first support connecting section extends along a first direction and has a first support end and a second support end at both ends, the welding gun is arranged on one side of the second support end, and the second support connecting section is connected to the second support end and the welding gun at both sides, and the welding head of the welding gun is arranged towards the first support end.

[0006] Adopting the technical scheme, the welding mechanism can weld the internal welding seam formed at the connection of the first to-be-welded object and the second to-be-welded object when the first to-be-welded object is installed to the connecting opening of the second to-be-welded object. Specifically, the operator can insert the end of the welding mechanism provided with a welding gun into the second to-be-welded object through the welding object inner hole of the first to-be-welded object, and since the welding head of the welding gun is arranged towards the first support end, at this time, the welding head of the welding gun is arranged towards the connecting opening side of the second to-be-welded object. The welding mechanism moves in the second direction perpendicular to the first direction by a certain distance, so that the welding head of the welding mechanism is aligned with the internal welding seam. The welding mechanism or the second to-be-welded object is moved, so that the movement path of the welding mechanism or the second to-be-welded object matches the shape of the internal welding seam. For example, if the internal welding seam is circular, the movement path of the welding mechanism or the second to-be-welded object is circular, i.e. rotation. If the internal welding seam is square, the movement path of the welding mechanism or the second to-be-welded object is square, so that the internal welding seam can be welded and sealed. The above technical scheme greatly facilitates the welding work of the operator.

[0007] The above technical scheme makes the welding mechanism more reasonable, and can reduce the size of the end of the welding mechanism provided with the welding gun. In the second direction perpendicular to the first direction, the distance from the side of the welding gun away from the second support end to the side of the second support end away from the welding gun can be less than or equal to the aperture of the welding object inner hole of the first to-be-welded object. Specifically, in the second direction, the distance from the side of the welding gun away from the second support end to the side of the second support end away from the welding gun can be 40 mm, which can perfectly solve the welding problem of the internal welding seam formed by the first to-be-welded object and the second to-be-welded object when the welding object inner hole of the first to-be-welded object is a small hole.

[0008] Further, the welding gun is an argon arc welding gun, the support connecting piece is hollow to form an air pipe, and the second support connecting section of the support connecting piece is connected and communicated with the gas inlet of the welding gun.

[0009] The above technical scheme makes the welding mechanism more reasonable and integrated, and makes it better to insert into the second to-be-welded object through the welding object inner hole of the first to-be-welded object.

[0010] The welding device for welding the internal weld joint formed when the first to-be-welded object is installed to the connecting opening of the second to-be-welded object, comprising: a welding mechanism, a to-be-welded object driving mechanism, and a base frame, wherein the welding mechanism adopts the welding mechanism described above, the to-be-welded object driving mechanism comprises a to-be-welded object carrying platform for carrying the second to-be-welded object on which the first to-be-welded object is installed, and the base frame comprises a base plate, and the to-be-welded object carrying platform is located on one side of the base plate and movably arranged on the base plate.

[0011] Specifically, the movement path of the to-be-welded object carrying platform relative to the base plate matches the shape of the internal weld joint, for example, if the internal weld joint is circular, the movement path of the to-be-welded object carrying platform is circular, i.e., rotation; if the internal weld joint is square, the movement path of the to-be-welded object carrying platform is square.

[0012] Alternatively, the welding mechanism can be movably arranged, and the movement of the to-be-welded object carrying platform is matched with the movement of the welding mechanism so that the path of the movement of the welding head relative to the second to-be-welded object matches the shape of the internal weld joint, for example, if the internal weld joint is square, the welding mechanism moves to match one side of the internal weld joint, and the to-be-welded object carrying platform rotates so that the welding head can be aligned with the adjacent side in the internal weld joint and moves, and the cycle is repeated to realize the matching of the trajectory and the shape of the internal weld joint. Of course, there are many other combinations, and the rotation of the to-be-welded object carrying platform plus the translation of the welding mechanism can be combined into various paths.

[0013] With the above technical solution, the operator can first install the first to-be-welded object to the connecting opening of the second to-be-welded object, and then weld and seal the external weld joint of the first to-be-welded object and the second to-be-welded object to realize the external welding work; after completion, the second to-be-welded object on which the first to-be-welded object is installed is placed on the to-be-welded object carrying platform, the welding mechanism is extended into the second to-be-welded object, and the welding head is aligned with the internal weld joint; at this time, the to-be-welded object carrying platform is moved, and since the movement path of the to-be-welded object carrying platform matches the shape of the internal weld joint, the welding head of the welding gun moves along the internal weld joint relative to the second to-be-welded object, so that the welding gun welds the internal weld joint; or the to-be-welded object carrying platform moves and the welding mechanism moves to weld the internal weld joint; finally, the welding mechanism is withdrawn from the second to-be-welded object to realize the welding of the internal weld joint generated when the first to-be-welded object is installed; if the second to-be-welded object is installed with multiple first to-be-welded objects, the operator can operate the second to-be-welded object to cycle the above operation to weld all the internal weld joints.

[0014] The technical scheme perfectly solves the welding problem of the internal weld joint formed by the first to-be-welded object and the second to-be-welded object when the inner hole of the welding object of the first to-be-welded object is a small hole, and greatly improves the welding efficiency and quality of the product, the welding seam is flat, the welding precision is greatly improved, and the probability of welding failure is reduced.

[0028] The above technical solutions facilitate an operator to rotate the second to-be-welded object, and facilitate actual operation; for example, a plurality of first to-be-welded objects need to be arranged on the second to-be-welded object, after the internal welding seam formed by one first to-be-welded object is welded, the operator can lift the second to-be-welded object, so that the first to-be-welded object is separated from the positioning groove, and after rotating by a certain angle, the second to-be-welded object can be placed down, at this time, the operator can rotate the second to-be-welded object to the next first to-be-welded object by means of the caster, lift the second to-be-welded object, and place the first to-be-welded object in the positioning groove.

[0029] Further, the welding device comprises a welding driving mechanism connected with the welding mechanism for driving the welding mechanism to move along a first direction and for driving the welding mechanism to move along a second direction perpendicular to the first direction.

[0030] With the above technical solutions, the welding device is more reasonable and automated. The welding driving mechanism drives the welding mechanism to move along the first direction so that the end of the welding mechanism provided with a welding gun extends into the second to-be-welded object through the inner hole of the welding object of the first to-be-welded object. The welding driving mechanism drives the welding mechanism to move along the second direction so that the welding head of the welding gun is aligned with the internal welding seam. The welding driving mechanism is reversely driven to reset.

The side of the second connecting and fixing block facing the first connecting and fixing block is recessed with a second connecting and fixing groove matched with the first supporting and connecting segment.

[0032] With the above technical solutions, the first connecting and fixing block and the second connecting and fixing block are matched to clamp the first supporting and connecting segment, thereby realizing the connection between the welding driving mechanism and the welding mechanism.

Those of ordinary skill in the art can understand the specific meanings of the above terms in the present application according to specific circumstances.

[0090] The technical scheme provided by the embodiments of the present application is described below with reference to the drawings.

[0091] Referring to Figure 1 The utility model provides a kind of welding mechanism 1, comprising: welding torch 101 and support connecting piece 102, the welding torch 101 has welding head 1011, the support connecting piece 102 includes first support connecting section 1021 and second support connecting section 1022, the first support connecting section 1021 is extended along first direction and its two ends are formed into first support end 1021-1 and second support end 1021-2 respectively, the welding torch 101 is arranged at the side of second support end 1021-2, and the two sides of second support connecting section 1022 are connected with second support end 1021-2 and welding torch 101 respectively, and the welding head 1011 of welding torch 101 is arranged towards first support end 1021-1.

[0092] By the above technical scheme, the welding mechanism 1 can weld the internal weld joint 300 formed at the connection of the first and second objects to be welded when the first object to be welded is installed to the connection opening 200-1 of the second object to be welded. Specifically, the operator can insert the end of the welding mechanism 1 provided with the welding torch 101 into the second object to be welded through the object inner hole 100-1 of the first object to be welded, and since the welding head 1011 of the welding torch 101 is arranged towards the first support end 1021-1, the welding head 1011 of the welding torch 101 is arranged towards the side of the connection opening 200-1 of the second object to be welded at this time. The welding mechanism 1 moves a certain distance in the second direction perpendicular to the first direction, so that the welding head 1011 of the welding mechanism 1 is aligned with the internal weld joint 300. The welding mechanism 1 or the second object to be welded is moved so that the movement path of the welding mechanism 1 or the second object to be welded matches the shape of the internal weld joint 300. For example, if the internal weld joint 300 is circular, the movement path of the welding mechanism 1 or the second object to be welded is circular, i.e. rotation. If the internal weld joint 300 is square, the movement path of the welding mechanism 1 or the second object to be welded is square, so that the internal weld joint 300 can be welded and sealed. The above technical scheme greatly facilitates the welding work of the operator.

[0093] And the above technical solution makes the welding mechanism 1 more reasonable, and can reduce the size of the welding mechanism 1 provided with the welding gun 101 at one end. In the second direction perpendicular to the first direction, the distance from the side of the welding gun 101 away from the second support end 1021-2 to the side of the second support end 1021-2 away from the welding gun 101 can be less than or equal to the hole diameter of the welding hole 100-1 of the first welding object 100. Specifically, in the second direction, the distance from the side of the welding gun 101 away from the second support end 1021-2 to the side of the second support end 1021-2 away from the welding gun 101 can be 40mm, which can perfectly solve the welding problem of the internal weld joint 300 formed by the first welding object 100 and the second welding object 200 when the welding hole 100-1 of the first welding object 100 is a small hole.

[0094] Further, the welding gun 101 is an argon arc welding gun 101, and the support connecting piece 102 is hollow to form an air pipe. The second support connecting section 1022 of the support connecting piece 102 is connected and communicated with the gas inlet of the welding gun 101.

[0095] The above technical solution makes the welding mechanism 1 more reasonable and the structure more integrated and simplified, so that it can better extend into the interior of the second welding object 200 through the welding hole 100-1 of the first welding object 100.

[0096] Referring to Figures 1 to 7 A welding device for welding the internal weld joint 300 formed by the connection of the first welding object 100 to the connection opening 200-1 of the second welding object 200, comprising a welding mechanism 1, a welding object driving mechanism 3, and a base frame 12. The welding mechanism 1 adopts the welding mechanism 1 described above. The welding object driving mechanism 3 comprises a welding object carrying platform 302 for carrying the second welding object 200 provided with the first welding object 100. The base frame 12 comprises a base plate 1201, and the welding object carrying platform 302 is located on one side of the base plate 1201 and movably arranged on the base plate 1201.

[0097] Specifically, the movement path of the welding object carrying platform 302 relative to the base plate 1201 matches the shape of the internal weld joint 300. For example, if the internal weld joint 300 is circular, the movement path of the welding object carrying platform 302 is circular, i.e. rotation. If the internal weld joint 300 is square, the movement path of the welding object carrying platform 302 is square.

[0098] Or the welding mechanism 1 can be movably arranged, the movement of the to-be-welded object carrying platform 302 is matched with the movement of the welding mechanism 1, so that the path of the movement of the welding head 1011 relative to the second to-be-welded object 200 matches the shape of the internal welding seam 300, for example, if the internal welding seam 300 is square, the welding mechanism 1 moves to match one side of the internal welding seam 300, and the to-be-welded object carrying platform 302 rotates, so that the welding head 1011 can be aligned with the adjacent side in the internal welding seam 300 and moved, and the cycle is implemented to match the trajectory with the shape of the internal welding seam 300, and of course there are many other combinations, the rotation of the to-be-welded object carrying platform 302 and the translation of the welding mechanism 1 can be combined into various paths.

[0099] With the above technical scheme, the operator can first install the first to-be-welded object 100 to the connecting opening 200-1 of the second to-be-welded object 200, and then weld and seal the external welding seam of the first to-be-welded object 100 and the second to-be-welded object 200 to realize external welding work; after completion, the second to-be-welded object 200 with the first to-be-welded object 100 installed is placed on the to-be-welded object carrying platform 302, the welding mechanism 1 is inserted into the second to-be-welded object 200, and the welding head 1011 is aligned with the internal welding seam 300; at this time, the to-be-welded object carrying platform 302 is moved, and since the movement path of the to-be-welded object carrying platform 302 matches the shape of the internal welding seam 300, the welding head 1011 of the welding gun 101 moves along the internal welding seam 300 relative to the second to-be-welded object 200, so that the welding gun 101 welds the internal welding seam 300 at this position, or the to-be-welded object carrying platform 302 moves and the welding mechanism 1 moves to weld the internal welding seam 300; finally, the welding mechanism 1 is withdrawn from the second to-be-welded object 200 to realize welding of the internal welding seam 300 generated when the first to-be-welded object 100 is installed; if the second to-be-welded object 200 is installed with multiple first to-be-welded objects 100, the operator can operate the second to-be-welded object 200 to cycle the above operation to weld all the internal welding seams 300;

[0100] The above technical scheme perfectly solves the welding problem of the internal welding seam 300 formed by the first to-be-welded object 100 and the second to-be-welded object 200 when the hole 100-1 of the first to-be-welded object 100 is a small hole, and greatly improves the welding efficiency and quality of the product, the welding seam is flat, greatly improves the welding precision, and reduces the probability of welding failure.

[0101] Further, the internal welding seam 300 is circular, and the to-be-welded object carrying platform 302 is arranged to rotate relative to the base plate 1201.

[0102] Adopting the technical scheme makes the welding equipment more reasonable.

[0104] The welding object bearing platform 302 is provided with a first welding cooperation through hole 3024 through which one end of the welding gun 101 provided with the welding mechanism 1 can pass, and when the second welding object 200 provided with the first welding object 100 is placed on the welding object bearing platform 302 and the connecting opening 200-1 faces the side of the welding object bearing platform 302, the first welding cooperation through hole 3024 is opposite to the welding object inner hole 100-1 of the first welding object 100; the bearing platform connecting shaft 3012 is provided with a second welding cooperation through hole 3012-1 at a position opposite to the first welding cooperation through hole 3024, and the second welding cooperation through hole 3012-1 can accommodate one end of the welding gun 101 provided with the welding mechanism 1; at least one end of the welding gun 101 provided with the welding mechanism 1 is telescopically arranged in the first welding cooperation through hole 3024 and the second welding cooperation through hole 3012-1, and the axis direction of the first welding cooperation through hole 3024 and the second welding cooperation through hole 3012-1 is the first direction.

[0105] Adopting the technical scheme makes the welding equipment more reasonable.

[0106] Further, the base plate 1201 is provided with a connecting shaft cooperation hole 12011, and the base plate 1201 is provided with a bearing seat 13 at the connecting shaft cooperation hole 12011, the bearing platform connecting shaft 3012 passes through the bearing seat 13, and the bearing 14 is arranged between the outer wall of the bearing platform connecting shaft 3012 and the bearing seat 13.

[0107] Adopting the technical scheme, the base frame 12 provides installation support basis for other mechanisms of the welding equipment; the arrangement of the bearing 14 can reduce the friction of the rotation of the bearing platform connecting shaft 3012, and make the rotation of the bearing platform connecting shaft 3012 more stable;

[0108] Specifically, the bearing 14 comprises a first bearing 1401 and a second bearing 1402, the first bearing 1401 is arranged closer to the base plate 1201 than the second bearing 1402, a spacer sleeve 15 is arranged between the first bearing 1401 and the second bearing 1402, the first bearing 1401 adopts a tapered roller bearing 14, and the second bearing 1402 adopts a deep groove ball bearing 14.

[0109] Further, the base frame 12 comprises a plurality of base frame legs 1202, and the plurality of base frame legs 1202 are arranged on a side of the base plate 1201 away from the object to be welded carrying platform 302.

[0110] By adopting the technical scheme, the welding equipment is more reasonable, specifically, the base frame legs 1202 are four in number and are respectively located at four corners of the base plate 1201.

[0111] Further, the object to be welded carrying platform 302 comprises a carrying platform body 3021, a positioning plate 3022, and a plurality of supporting pieces 3023, the positioning plate 3022 is arranged on the carrying platform body 3021, and the positioning plate 3022 is recessed to form a positioning groove 3022-1 matched with a part of the first object to be welded 100 protruding from the second object to be welded 200, and the plurality of supporting pieces 3023 are arranged on the carrying platform body 3021 and surround the positioning plate 3022, and the height of the supporting piece 3023 is matched with the distance from the carrying platform body 3021 at the position to the outer wall of the second object to be welded 200.

[0112] By adopting the technical scheme, the object to be welded carrying platform 302 is more reasonable, the positioning plate 3022 can facilitate the operator to position and place the second object to be welded 200 with the first object to be welded 100 on the carrying platform body 3021, and the plurality of supporting pieces 3023 can enable the second object to be welded 200 with the first object to be welded 100 to be stably and reliably placed on the carrying platform body 3021, specifically, the supporting pieces 3023 are four in number.

[0113] Further, the second object to be welded 200 is in a cylindrical structure, the supporting piece 3023 comprises a caster 3023-1 and a caster support 3023-2, the caster support 3023-2 is arranged on the carrying platform body 3021, the caster 3023-1 is rotationally arranged on the caster support 3023-2, and the rotation axis of the caster 3023-1 is parallel to the axis of the second object to be welded 200.

[0114] With the above technical scheme, the operator can rotate the second welding object 200, which is convenient for actual operation. For example, if multiple first welding objects 100 need to be installed on the second welding object 200, after the internal welding seam 300 formed by one first welding object 100 is welded, the operator can lift the second welding object 200, so that the first welding object 100 at this position is separated from the positioning groove 3022-1, and then the second welding object 200 is rotated by a certain angle and then is placed down. At this time, the operator can rotate the second welding object 200 to the next first welding object 100 by means of the castor 3023-1, lift the second welding object 200, and then put the first welding object 100 at this position into the positioning groove 3022-1.

[0115] Further, the welding device comprises a welding driving mechanism 2 connected with the welding mechanism 1 for driving the welding mechanism 1 to move along a first direction and for driving the welding mechanism 1 to move along a second direction perpendicular to the first direction.

[0116] With the above technical scheme, the welding device is more reasonable and automatic. The welding driving mechanism 2 drives the welding mechanism 1 to move along the first direction, so that one end of the welding mechanism 1 provided with the welding gun 101 extends into the second welding object 200 through the welding object inner hole 100-1 of the first welding object 100. The welding driving mechanism 2 drives the welding mechanism 1 to move along the second direction, so that the welding head 1011 of the welding gun 101 is aligned with the internal welding seam 300.

The side of the first connecting and fixing block 2011 facing the second connecting and fixing block 2012 is recessed to be provided with a first connecting and fixing groove 2011-1 matched with the first supporting and connecting section 1021. The side of the second connecting and fixing block 2012 facing the first connecting and fixing block 2011 is recessed to be provided with a second connecting and fixing groove 2012-1 matched with the first supporting and connecting section 1021.

[0118] With the above technical scheme, the first connecting and fixing block 2011 and the second connecting and fixing block 2012 are matched to clamp the first supporting and connecting section 1021, so as to realize the connection between the welding driving mechanism 2 and the welding mechanism 1.

[0119] The detachable connection of the first connecting fixed block 2011 and the second connecting fixed block 2012 enables the welding connection fixed structure 201 to release the welding mechanism 1, that is, the welding mechanism 1 can be separated from the welding driving mechanism 2, thereby achieving daily maintenance and equipment replacement; specifically, the first connecting fixed block 2011 and the second connecting fixed block 2012 are detachably connected through bolts.
