High flatness aluminum plate welding device

Abstract

This invention proposes a high-flatness aluminum plate welding device, including a machine body support, a material conveying track, an adjustment device, and welding components. The machine body support includes a base plate, on which a pair of slide rails are connected via a supporting frame. Two sets of material conveying tracks are connected between the two slide rails. The material conveying tracks include an loading roller conveyor, an adjustment plate area, and a unloading roller conveyor. An adjustment device is provided at the position of the material conveying track corresponding to the adjustment plate area. After the aluminum plate is transported to the adjustment plate area by the loading roller conveyor, a limiting block at the end of the slide block restricts it to a uniform material conveying position. The adjustment motor drives the lead screw, causing the movable plate to move inwards towards the material conveying track. At this time, the material-dispensing side bracket dispensing the outer plate of the aluminum plate brings the two aluminum plates together, forming a weld. Finally, the telescopic rod driven by the limiting electromagnetic telescopic extension extends until a nylon pressure plate presses down on the aluminum plate, thus keeping the aluminum plate in a fixed state during welding. The automatic positioning capability is convenient and effective.

An adjustment motor is provided on the outer side of the adjustment main bracket, and the output shaft of the adjustment motor is connected to the lead screw via a transmission connection. A limiting electromagnetic telescopic drive is provided on the movable plate seat. The telescopic rod of the limiting electromagnetic telescopic drive extends in a direction perpendicular to the plane of the material conveying track, and a nylon pressure plate is provided at the end of the telescopic rod. A welding assembly is provided directly above the two sets of material conveying tracks. The welding assembly includes a welding lifting drive. The telescopic rod of the welding lifting drive extends vertically downwards, and a welding base is connected to the lower end of the telescopic rod. A welding box is provided on the welding base, and the welding gun of the welding box is located at the bottom of the welding box.

[0006] Preferably, an angle-adjusting electromagnetic hydraulic telescopic drive is provided on the base plate and at the position corresponding to each joint support. The telescopic rod of the angle-adjusting electromagnetic hydraulic telescopic drive extends vertically upward, and the upper end of the telescopic rod of the angle-adjusting electromagnetic hydraulic telescopic drive is connected to the corresponding joint support. An angle sensor is provided at the bottom of the material conveying track.

[0007] Preferably, the sliding shaft and lead screw are arranged parallel to the plane of the material conveying track, and the axial direction of the sliding shaft and lead screw is perpendicular to the material conveying direction of the material conveying track.

[0008] Preferably, the outer sides of the feeding roller conveyor and the unloading roller conveyor are integrally formed with fixed side roller supports, and a row of fixed side roller conveyors is provided on the inner side of the fixed side roller supports.

[0009] Preferably, the inner side of the feeding side bracket is provided with a row of movable side rollers, and the guiding direction of the movable side rollers is consistent with the guiding direction of the material conveying track.

[0010] Preferably, a limiting block is integrally formed at one end of the feeding side bracket near the feeding roller conveyor, and the limiting block and the feeding side bracket form a right angle.

[0011] Preferably, the upper surface of the adjustment plate area is fitted with a plurality of ball bearings, which are arranged in a matrix on the upper surface of the adjustment plate area.

[0012] Preferably, the cross-section of the welding base is an inverted "concave" structure, and a row of nylon pressure rollers is connected to the inner sidewalls of both sides of the welding base.

[0013] Preferably, a suction pipe is connected between the multiple combined supports, and the suction pipe is located in the middle of the two sets of material conveying tracks.

[0014] Preferably, the length of the suction pipe is consistent with the material guiding direction of the conveying track, and the suction port of the suction pipe is located at the top.

[0015] The beneficial effects of this invention are:

[0016] 1. This invention controls the extension and retraction of the telescopic rod driven by the electromagnetic hydraulic angle adjustment, thereby adjusting the inner protrusion or descent of the two sets of material conveying tracks. This allows for adjustment of the welding angle of the two aluminum plates placed on the two sets of material conveying tracks before welding. Fixed side roller supports are integrally formed on the outer sides of the feeding roller track and the unloading roller track, and a row of fixed side roller tracks is provided on the inner side of the fixed side roller supports. When the two material conveying tracks are tilted, they are used to support the outer sides of the aluminum plates and facilitate the material conveying of the aluminum plates. The upper surface of the adjustment plate area is equipped with ball bearings arranged in a matrix, which greatly reduces the wear of the aluminum plates when they move on the adjustment plate area.

[0017] 2. In this invention, after the aluminum plate is transported to the adjustment plate area by the feeding roller conveyor, the forward direction of the aluminum plate is restricted by the limiting block set at the end of the slide block, so that the two aluminum plates are in the same feeding position. Then, the adjusting motor drives the lead screw to move the movable plate seat to the inside of the feeding track. At this time, the material feeding side bracket pushes the outer plate of the aluminum plate, so that the two aluminum plates come together to form a weld. Finally, the telescopic rod driven by the limiting electromagnetic telescopic extension is extended until the nylon pressure plate presses against the aluminum plate, so that the aluminum plate remains in a fixed state during the welding process. The automatic positioning capability is convenient and effective.

[0018] 3. This invention controls the welding lifting drive to lower the welding base until the two rows of nylon pressure rollers at the bottom of the welding base press down on both sides of the aluminum plate weld, further ensuring stability during the welding process and improving the stability of the welding torch. At the same time, with the operation of the air pump equipment box, the fumes generated during the welding process are absorbed by the air extraction pipe and discharged in a unified manner to reduce pollution. Meanwhile, the airflow quickly lowers the temperature of the weld after welding, avoiding thermal deformation caused by excessive temperature and improving welding accuracy.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please refer to Figure 1 , Figure 4 and Figure 6 As shown, the present invention proposes a high-flatness aluminum plate welding device, including a machine body support, a material conveying track 2, an adjustment device 3, and a welding assembly 4. The machine body support includes a base plate 1, on which a pair of horizontally and parallel slide rails 102 are connected via a support frame 101. Two sets of material conveying tracks 2 are connected between the two slide rails 102. Two aluminum plates to be welded are placed on the two sets of material conveying tracks 2 respectively. Slide seats 204 are provided at both ends of the outer side of the material conveying tracks 2, and the slide seats 204 at both ends of the outer side of the material conveying tracks 2 are respectively connected to the two slide rails 102.

The connecting ends are connected, and an angle-adjusting electromagnetic hydraulic telescopic drive 206 is provided on the base plate 1 and at the position corresponding to each joint support 205. The telescopic rod of the angle-adjusting electromagnetic hydraulic telescopic drive 206 extends vertically upward, and the upper end of the telescopic rod of the angle-adjusting electromagnetic hydraulic telescopic drive 206 is connected to the corresponding joint support 205. By controlling the telescopic rod of the angle-adjusting electromagnetic hydraulic telescopic drive 206 to extend or retract, the inner convexity or descent of the two sets of material conveying tracks 2 can be adjusted, thereby adjusting the welding angle of the two aluminum plates placed on the two sets of material conveying tracks 2 before welding. An angle sensor 208 is provided at the bottom of the material conveying track 2 to detect the inclination of the material conveying track 2, thereby calculating the welding angle between the two aluminum plates.

[0029] It is worth mentioning that the material conveying track 2 includes an loading roller conveyor 201, an adjusting plate area 202, and an unloading roller conveyor 203. The adjusting plate area 202 is located in the middle of the material conveying track 2. Figure 1 and Figure 6 As shown, both the outer sides of the feeding roller conveyor 201 and the unloading roller conveyor 203 are integrally formed with fixed side roller supports 207, and the inner side of the fixed side roller supports 207 is provided with a row of fixed side rollers 2071. When the two conveying tracks 2 are tilted, they are used to support the outer sides of the aluminum plate and facilitate the conveying of the aluminum plate. Figure 2 , Figure 3 and Figure 4As shown, the upper surface of the adjustment plate area 202 is fitted with a number of ball bearings 2021. The ball bearings 2021 are arranged in a matrix on the upper surface of the adjustment plate area 202, which greatly reduces the wear of the aluminum plate when it moves on the adjustment plate area 202.

[0030] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: The present invention controls the extension and retraction of the telescopic rod of the angle-adjusting electromagnetic hydraulic telescopic drive 206, thereby adjusting the inner protrusion or descent of the two sets of material conveying tracks 2, thereby adjusting the welding angle of the two aluminum plates placed on the two sets of material conveying tracks 2 before welding.

[0032] Combination Figure 2 , Figure 5 and Figure 6 As shown, an adjustment device 3 is provided at the position of the adjustment plate area 202 corresponding to the material conveying track 2. The adjustment device 3 includes an adjustment main support 301 fixed to the outside of the material conveying track 2. The support body of the adjustment main support 301 extends horizontally towards the inside of the material conveying track 2. The adjustment main support 301 is provided with a sliding shaft 302 and a lead screw 3021 arranged in parallel. The sliding shaft 302 and the lead screw 3021 are arranged parallel to the plane of the material conveying track 2, and the axial direction of the sliding shaft 302 and the lead screw 3021 is perpendicular to the material conveying direction of the material conveying track 2. A movable plate seat 303 is connected to the bottom of the sliding shaft 302 and the lead screw 3021. A material-pulling side support 304 is integrally formed on the bottom outer edge of the movable plate seat 303. A pair of connecting seats 3031 are provided on the seat 303. One of the connecting seats 3031 on the movable plate seat 303 is slidably connected to the sliding shaft 302. The other connecting seat 3031 on the movable plate seat 303 is engaged with the lead screw 3021 through thread meshing. An adjustment motor 3022 is provided on the outside of the adjustment main support 301, and the output shaft end of the adjustment motor 3022 is connected to the lead screw 3021 for transmission. When the aluminum plate is transported from the feeding roller conveyor 201 to the adjustment plate area 202, the adjustment motor 3022 is controlled to drive the lead screw 3021, so that the movable plate seat 303 moves to the inside of the material conveying track 2. At this time, the material-pushing side support 304 pushes the outer plate of the aluminum plate, so that the two aluminum plates come together to form a weld.

[0033] Combination Figure 2 , Figure 3 and Figure 6As shown, the inner side of the feeding side support 304 is provided with a row of movable side rollers 3041. The guide of the movable side rollers 3041 is consistent with the guiding direction of the material conveying track 2. It is used to support the outer side of the aluminum plate and facilitate the material conveying of the aluminum plate. The end of the feeding side support 304 near the unloading roller 203 is integrally formed with a limiting block 3042. The limiting block 3042 and the feeding side support 304 form a right angle. The limiting block 3042 is used to restrict the forward direction of the aluminum plate material conveying, so that the two aluminum plates are in the same material conveying position.

[0034] It is worth mentioning that, such as Figure 4 and Figure 6 As shown, the movable plate base 303 is provided with a limiting electromagnetic telescopic drive 305. The telescopic rod of the limiting electromagnetic telescopic drive 305 is set in a plane perpendicular to the material conveying track 2, and the end of the telescopic rod of the limiting electromagnetic telescopic drive 305 is provided with a nylon pressure plate 3051. After the two aluminum plates are welded together, the telescopic rod of the limiting electromagnetic telescopic drive 305 is controlled to extend until the nylon pressure plate 3051 presses against the aluminum plate, thereby keeping the aluminum plate in a fixed state during the welding process.

[0035] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: After the aluminum plate is transported to the adjustment plate area 202 by the feeding roller conveyor 201, the limiting block 3042 provided at the end of the slide block 204 restricts the forward direction of the aluminum plate, thereby placing the two aluminum plates in the same feeding position. Then, by controlling the adjustment motor 3022 to drive the lead screw 3021, the movable plate seat 303 moves to the inside of the feeding track 2. At this time, the material feeding side bracket 304 pushes the outer plate of the aluminum plate, so that the two aluminum plates come together to form a weld. Finally, by controlling the extension rod of the limiting electromagnetic extension drive 305 to extend until the nylon pressure plate 3051 presses the aluminum plate, thereby keeping the aluminum plate in a fixed state during the welding process. The automatic positioning capability is convenient and effective.

[0036] Example 3

[0037] Combination Figure 2 and Figure 6 As shown, a welding assembly 4 is positioned directly above the two sets of material conveying tracks 2. The welding assembly 4 includes a welding lifting drive 401. The welding assembly 4 is fixed to an external traveling support (not shown in the figure). The welding assembly 4 can move along the weld seam. The telescopic rod of the welding lifting drive 401 extends vertically downward. The lower end of the telescopic rod of the welding lifting drive 401 is connected to a welding base 402. A welding box 403 is provided on the welding base 402, and the welding gun 4031 of the welding box 403 is located at the bottom of the welding box 403. The welding gun 4031 of the welding box 403 is preferably a telescopic welding gun of the prior art, which is convenient for matching the distance of the weld seam.

[0038] It is worth mentioning that, such as Figure 6 As shown, the cross-section of the welding base 402 is an inverted "concave" structure. Each of the inner sidewalls of the two sides of the welding base 402 is connected to a row of nylon pressure rollers 4021. After the welding lifting drive 401 controls the welding base 402 to descend, the two rows of nylon pressure rollers 4021 press down on the parts on both sides of the aluminum plate weld, further ensuring the stability of the welding process, and also improving the stability of the welding torch 4031 during the welding process.

[0039] In addition, such as Figure 6 As shown, a suction pipe 5 is connected between multiple joint supports 205. The suction pipe 5 is located in the middle of the two sets of material conveying tracks 2. An air pump equipment box 501 is provided on the base plate 1, and the suction end of the air pump equipment box 501 is connected to the suction pipe 5 through a flexible air guide hose 502. The length of the suction pipe 5 is consistent with the material guiding direction of the material conveying track 2, and the suction port of the suction pipe 5 is located at the top. Under the operation of the air pump equipment box 501, the fumes generated during the welding process are absorbed by the suction pipe 5 and then discharged in a unified manner to reduce pollution. At the same time, the airflow quickly reduces the temperature of the weld after welding to avoid thermal deformation caused by excessive temperature.

[0040] The technical solutions described in the above embodiments of this application have at least the following technical effects or advantages: The present invention controls the welding lifting drive 401 to drive the welding base 402 to descend until the two rows of nylon pressure rollers 4021 at the bottom of the welding base 402 press down on both sides of the aluminum plate weld, further ensuring stability during the welding process and improving the stability of the welding torch 4031 during the welding process. At the same time, under the operation of the air pump equipment box 501, the exhaust pipe 5 absorbs the fumes generated during the welding process and discharges them in a unified manner to reduce pollution. Meanwhile, the airflow quickly reduces the temperature of the weld after welding, avoiding thermal deformation caused by excessively high temperatures and improving welding accuracy.

[0041] Of course, the present invention may have many other embodiments. Based on this embodiment, other embodiments obtained by those skilled in the art without any creative effort are all within the scope of protection of the present invention.
