High strength aluminum alloy frame welding apparatus

Abstract

This invention discloses a high-strength aluminum alloy frame welding device relating to the field of aluminum alloy production technology. The device includes a main frame, comprising a mounting platform on the main frame, with two solid plates fixedly mounted on the surface of the mounting platform. A limiting cylinder for positioning the main blank is fixedly mounted on the surface of each solid plate. The limiting mechanism includes two contour plates mounted on each solid plate for limiting the welding blank, and two guide platforms mounted on each solid plate. A sliding mechanism drives a rubber block to move obliquely to the upper left. At this time, the rubber block contacts the welding blank, causing the welding blank to rotate. As the welding blank rotates, the contact end between the welding blank and the contour plate completes the engagement. Once the contact end between the welding blank and the contour plate is engaged, the movement of the rubber block will not contact the welding blank, thereby completing the posture adjustment of the welding blank and achieving automatic adjustment of the welding blank to facilitate subsequent welding.

Description

Technical Field

[0001] This invention relates to the field of aluminum alloy production technology, and in particular to a high-strength aluminum alloy frame welding equipment. Background Technology

[0002] With the development of industry, aluminum alloys now account for a large proportion of finished product manufacturing. This is because aluminum alloys have high strength, with a specific strength close to that of high alloy steel and a specific stiffness exceeding that of steel. They also have good casting and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. They are widely used in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily necessities.

[0003] Currently, the production of aluminum alloy frames requires welding. However, because the welding surfaces between aluminum alloys are curved, precise positioning of the aluminum alloys is necessary before welding to avoid weld gaps. Currently, the equipment relies on manual adjustment of the orientation, resulting in very low welding efficiency.

[0004] Based on this, the present invention designs a high-strength aluminum alloy frame welding device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a high-strength aluminum alloy frame welding device, which aims to solve the technical problems existing in the prior art mentioned in the background.

Each guide platform is slidably connected to the contour plate through a straight sliding groove on its surface. The surface of the guide platform is also provided with a semi-circular groove for guiding the welding blank. Multiple rubber blocks are installed on the guide platform to drive the welding blank to rotate. A suspension frame is fixedly installed on the surface of the guide platform to facilitate contact between the rubber blocks and the welding blank. Sliding mechanism: used to drive the welding blank to rotate via a rubber block; Clamping mechanism: Fixes the welding blank by means of the revolution of the drive mechanism; Arc groove mechanism: The revolving action of the drive mechanism drives the contour plate to release the limiting position of the welding blank; Matching mechanism: The welding blank comes into contact with the main blank through the revolution of the driving mechanism.

[0007] Furthermore, the sliding mechanism includes a movable slider that is slidably connected to the inner wall of the guide platform. Multiple spaced rubber blocks are fixedly installed on the surface of the movable slider. The movable slider and the rotating lead screw form a helical pair transmission. The rotating lead screw passes through the interior of the guide platform and is rotatably connected to the guide platform. A lead screw gear is fixedly installed at one end of the rotating lead screw. A fixed rack and a reset rack that cooperate with the lead screw gear are fixedly installed on the surface of the solid plate.

[0008] Furthermore, the clamping mechanism includes a clamping block mounted on a guide platform, a sliding rod fixedly mounted on the surface of the clamping block, a compression spring fixedly mounted on the surface of the sliding rod, and an extrusion head fixedly mounted on the surface of the sliding rod. It also includes an arc-shaped block mounted on the guide platform that cooperates with the extrusion head. The arc-shaped block is fixedly mounted on a connecting plate, and the connecting plate is fixedly mounted on a bevel gear disk. The bevel gear disk meshes with a bevel gear, and a rotating gear is fixedly mounted on the other end of the bevel gear. A mating rack and a reversing rack that cooperate with the rotating gear are fixedly mounted on the surface of the solid plate.

[0009] Furthermore, the arc groove mechanism includes a connecting rod fixedly connected to the contour plate, and the inner wall of the solid plate is provided with an upper sliding groove, a lower slope sliding groove, a lower sliding groove, and an upper slope sliding groove that cooperate with the connecting rod and are smoothly connected end to end.

[0010] Furthermore, the mating mechanism includes a sliding block slidably connected to the guide table, a sliding rod passing through the sliding block and slidably connected to the sliding block, a compression spring connected to the sliding block at one end away from the sliding rod, a bevel gear disk rotatably connected to the sliding block, a follower rod fixedly mounted on the surface of the sliding block, the surface of the follower rod being rotatably connected to the bevel gear on the same axis, and an outer sliding groove, a mating groove, an inner sliding groove, and a reset groove that are smoothly connected in a head-to-tail sequence to the surface of the solid plate in accordance with the follower rod.

[0011] Furthermore, the drive mechanism includes a drive motor fixedly mounted on the mounting platform. The output end of the drive motor passes through the mounting platform and is rotatably connected to the mounting platform. A drive bevel gear is fixedly mounted on the output end of the drive motor. The drive bevel gear meshes with the driven cone disk. Two linkage rods are fixedly mounted on the surface of the driven cone disk. The other end of each linkage rod is connected to the guide table. The driven cone disk is rotatably connected to the surface of the mounting platform. Two adjacent guide tables that are not on the same circumference are connected by a follower linkage.

[0012] Furthermore, a ball bearing is rotatably mounted at the contact end between the extrusion head and the arc-shaped block.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a sliding mechanism to drive a rubber block to move obliquely to the upper left. At this time, the rubber block contacts the welding blank and drives the welding blank to rotate. As the welding blank rotates, the contact end of the welding blank and the template plate are engaged. After the contact end of the welding blank and the template plate are engaged, the movement of the rubber block will not contact the welding blank, thereby completing the posture adjustment of the welding blank and achieving the purpose of automatically adjusting the welding blank to facilitate subsequent welding.

[0014] 2. The present invention uses a cooperating mechanism to cause the guide table to bring the surface of the welding blank into contact with the surface of the main blank when it rotates 90 degrees, thereby completing the docking of the welding blank and the main blank. Then, the welding blank and the main blank are welded together by external welding equipment, thus achieving the purpose of automatically completing the docking welding. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0019] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, in one embodiment, a high-strength aluminum alloy frame welding device is provided, the device comprising: Main frame 1: includes a mounting platform 101 provided on the main frame 1. Two solid plates 102 are fixedly mounted on the surface of the mounting platform 101. A limiting cylinder 103 for positioning the main blank 104 is fixedly mounted on the surface of the solid plates 102. Limiting mechanism 2: includes two contour plates 201 installed on each solid plate 102 for limiting the welding blank 202, and two guide platforms 204 installed on each solid plate 102. Each guide platform 204 is slidably connected to the contour plate 201 through a straight sliding groove on its surface. The surface of the guide platform 204 is also provided with a semi-circular groove for guiding the welding blank 202. Multiple rubber blocks 203 are installed on the guide platform 204 for driving the welding blank 202 to rotate. A suspension frame 205 is fixedly installed on the surface of the guide platform 204 to facilitate contact between the rubber blocks 203 and the welding blank 202. Sliding mechanism 3: used to drive the welding blank 202 to rotate via the rubber block 203; Clamping mechanism 4: Fixes the welding blank 202 by means of the revolution of the drive mechanism 7; Arc groove mechanism 5: The rotation of the drive mechanism 7 drives the contour plate 201 to release the limit on the welding blank 202; Mechanism 6: The revolution of the drive mechanism 7 causes the welding blank 202 to come into contact with the main blank 104.

[0020] In practical applications, when performing welding operations, as described in the embodiments of the present invention... Figure 1 As shown, at this time, the main blank 104 is placed in the limiting cylinder 103 for positioning by an external gripping device, as shown. Figure 4 As shown, the welding blank 202 is simultaneously conveyed to the semi-circular groove of the left guide table 204 by an external conveying device. At this time, the guide table 204 is driven to revolve by the drive mechanism 7. The welding blank 202 slides along the semi-circular groove of the guide table 204 by its own weight. When the welding blank 202 is blocked by the contour plate 201, it is limited. If the contact end between the welding blank 202 and the contour plate 201 is not fully engaged, then during the revolution, from Figure 4 Looking from the front direction, the sliding mechanism 3 drives the rubber block 203 to move diagonally to the upper left. At this time, the rubber block 203 contacts the welding blank 202, causing the welding blank 202 to rotate. As the welding blank 202 rotates, the contact end of the welding blank 202 and the contour plate 201 are engaged. It should be noted that after the contact end of the welding blank 202 and the contour plate 201 are engaged, the movement of the rubber block 203 will not contact the welding blank 202, thus completing the posture adjustment of the welding blank 202 and achieving the purpose of automatically adjusting the welding blank 202 to facilitate subsequent welding. At this time, as the guide table 204 continues to revolve, as... Figure 6 As shown, the clamping mechanism 4 secures the welding blank 202, while the guide table 204 continues to rotate. Figure 2As shown, the arc groove mechanism 5 causes the contour plate 201 to no longer limit the welding blank 202, as... Figure 6 and Figure 7 As shown, the action of the cooperating mechanism 6 causes the guide table 204 to rotate 90 degrees, causing the surface of the welding blank 202 to come into contact with the surface of the main blank 104, thereby completing the docking of the welding blank 202 and the main blank 104. Then, the welding blank 202 and the main blank 104 are welded together by external welding equipment, achieving the purpose of automatic mating welding. At the same time, after the welding is completed, the clamping mechanism 4 is reset and the cooperating mechanism 6 is reset, so that the clamping mechanism 4 no longer restricts the welding blank 202. At this time, the welded main blank 104 is taken out by external gripping equipment, thereby completing the welding unloading operation. After the guide table 204 rotates 180 degrees, the adjacent guide tables 204 on the same circumference move to the starting position of the working guide table 204, thereby achieving the purpose of cyclic feeding welding.

[0021] like Figure 4 , Figure 8 and Figure 9 As shown, in a preferred embodiment of the present invention, the sliding mechanism 3 includes a movable slider 301 that is slidably connected to the inner wall of the guide platform 204. A plurality of mutually spaced rubber blocks 203 are fixedly installed on the surface of the movable slider 301. The movable slider 301 and the rotating screw 302 form a helical pair transmission. The rotating screw 302 passes through the interior of the guide platform 204 and is rotatably connected to the guide platform 204. A screw gear 303 is fixedly installed at one end of the rotating screw 302. A fixed rack 304 and a reset rack 305 that cooperate with the screw gear 303 are fixedly installed on the surface of the solid plate 102.

[0022] In practical applications, when the welding blank 202 slides on the guide table 204 under the action of gravity and comes into contact with the contour plate 201, as in the embodiment of the present invention... Figure 4 and Figure 8As shown, the continued revolution of the guide table 204 drives the lead screw gear 303 to engage with the fixed rack 304, causing the lead screw gear 303 to rotate. The rotation of the lead screw gear 303 drives the moving slider 301 to move obliquely to the upper left through the action of the lead screw slider, which in turn drives the rubber block 203 to move obliquely to the upper left. The contact between the rubber block 203 and the welding blank 202 causes the welding blank 202 to rotate through friction. After the welding blank 202 and the contour plate 201 are engaged, the welding blank 202 slides a distance along the semi-circular groove of the guide table 204 under the action of gravity. At this time, the movement of the rubber block 203 will not contact the welding blank 202, thereby achieving the purpose of automatically completing the orientation adjustment of the welding blank 202 before welding. After welding is completed, the moving slider 301 is reset through the engagement of the lead screw gear 303 and the reset rack 305, thereby achieving the purpose of automatic cyclic welding.

[0023] like Figure 4 , Figure 6 and Figure 7 As shown, in another preferred embodiment of the present invention, the pressing mechanism 4 includes a pressing block 401 mounted on the guide table 204, a sliding rod 402 fixedly mounted on the surface of the pressing block 401, a compression spring 403 fixedly mounted on the surface of the sliding rod 402, and an extrusion head 404 fixedly mounted on the surface of the sliding rod 402. It also includes an arc-shaped block 405 mounted on the guide table 204 and cooperating with the extrusion head 404. The arc-shaped block 405 is fixedly mounted on a connecting plate 406, which is fixedly mounted on a bevel gear 407. The bevel gear 407 meshes with a bevel gear 408, and a rotating gear 409 is fixedly mounted at the other end of the bevel gear 408. A mating rack 410 and a reversing rack 411 cooperating with the rotating gear 409 are fixedly mounted on the surface of the solid plate 102.

[0024] In practical applications, after the welding blank 202 has completed its posture adjustment, as in the embodiments of the present invention... Figure 4 and Figure 7 As shown, the rotation of the guide table 204 causes the rotating gear 409 to rotate in conjunction with the rack 410. The rotation of the rotating gear 409, through the engagement of the bevel gear set, drives the connecting plate 406 to rotate, which in turn drives the arc-shaped block 405 to rotate. As the radius of the arc-shaped block 405 gradually decreases, as... Figure 6As shown, at this time, the arc-shaped block 405 presses the pressing head 404 downward, and then the pressing block 401 presses the welding blank 202, thereby automatically completing the purpose of fixing the welding blank 202. After the welding is completed, the pressing block 401 stops pressing the welding blank 202 through the cooperation of the rotating gear 409 and the reverse rack 411. At the same time, the pressing block 401 is moved away from the welding blank 202 through the action of the cooperating mechanism 6, so as to avoid interference with the subsequent material cutting after the welding is completed.

[0025] like Figure 2 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in another preferred embodiment of the present invention, the arc groove mechanism 5 includes a connecting rod 501 fixedly connected to the contour plate 201, and the inner wall of the solid plate 102 is provided with an upper sliding groove 502, a lower slope sliding groove 503, a lower sliding groove 504 and an upper slope sliding groove 505 that cooperate with the connecting rod 501 and are smoothly connected end to end.

[0026] In practical applications, after the welding blank 202 is fixed, as in the embodiments of the present invention... Figure 11 As shown, at this time, the connecting rod 501 moves onto the downhill slide 503, as... Figure 2 As shown, from Figure 2 Looking directly at the workpiece, this causes the contour plate 201 to move diagonally upwards and to the right. At this point, the contour plate 201 no longer limits the welding blank 202, thus achieving automatic release of the limit. Simultaneously, as it continues to revolve around the guide table 204 after welding, as... Figure 13 As shown, the contour plate 201 is reset by the trajectory action of the uphill slide 505, thereby enabling cyclic welding.

[0027] like Figure 5 , Figure 6 and Figure 7 As shown, in another preferred embodiment of the present invention, the mating mechanism 6 includes a sliding block 601 slidably connected to the guide table 204, a sliding rod 402 passing through the sliding block 601 and slidably connected to the sliding block 601, a compression spring 403 having one end away from the sliding rod 402 connected to the sliding block 601, a bevel gear disk 407 rotatably connected to the sliding block 601, a follower rod 602 fixedly mounted on the surface of the sliding block 601, the surface of the follower rod 602 being coaxially rotatably connected to the bevel gear 408, and the surface of the solid plate 102 having an outer sliding groove 603, a mating groove 604, an inner sliding groove 605, and a reset groove 606 that are smoothly connected in a head-to-tail sequence to the follower rod 602.

[0028] In practical applications, when the limiting effect on the welding blank 202 is released, as in the embodiments of the present invention... Figure 6and Figure 7 As shown, at this time, the follower rod 602 moves to the position of the mating groove 604. Through the cooperation of the follower rod 602 and the mating groove 604, the follower rod 602 moves towards the center position close to the solid plate 102. Then, through the clamping mechanism 4, the welding blank 202 slides along the semi-circular groove of the guide table 204, so that the welding blank 202 approaches the main blank 104 and completes the docking with the main blank 104. At this time, the main blank 104 and the welding blank 202 are welded together by the external welding equipment, thereby achieving the purpose of automatic mating welding. After the welding is completed, the sliding block 601 is reset by the cooperation of the follower rod 602 and the reset groove 606, thereby performing cyclic welding operation.

[0029] like Figure 2 and Figure 3 As shown, in another preferred embodiment of the present invention, the driving mechanism 7 includes a driving motor 701 fixedly mounted on the mounting platform 101. The output end of the driving motor 701 passes through the mounting platform 101 and is rotatably connected to the mounting platform 101. A driving bevel gear 702 is fixedly mounted on the output end of the driving motor 701. The driving bevel gear 702 meshes with the driven cone disk 703. Two linkage rods 704 are fixedly mounted on the surface of the driven cone disk 703. The other end of each linkage rod 704 is connected to the guide table 204. The driven cone disk 703 is rotatably connected to the surface of the mounting platform 101. Two adjacent guide tables 204 that are not on the same circumference are connected by a follower link 705.

[0030] In practical applications, when the welding operation begins according to the embodiments of the present invention, such as Figure 3 As shown, at this time, the drive motor 701 starts to run. The operation of the drive motor 701 drives the driven cone disk 703 to rotate through the engagement of the bevel gear set, which in turn drives the guide table 204 to rotate through the linkage rod 704. Figure 2 As shown, the guide table 204 simultaneously drives the adjacent guide table 204, which is not on the same circumference, to revolve synchronously through the follower link 705, thereby achieving the purpose of synchronous welding of the two welding blanks 202.

[0031] like Figure 6 As shown, in another preferred embodiment of the present invention, a ball is rotatably mounted at the contact end between the extrusion head 404 and the arc-shaped block 405.

[0032] In practical applications, as shown in the figure of the cooperating mechanism 6, the rolling ball provided on the extrusion head 404 converts sliding friction into rolling friction, thereby reducing friction and improving the service life of the device.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
