Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a lightweight steel structure welding equipment. Background Art

[0002] Lightweight steel structures are building structures produced through assembly and are widely used in the fields of construction or engineering. In some special designs or engineering projects, such as roofs of factories and warehouses, lightweight steel structures are used for connection and support to provide connection points and install and fix various accessories.

[0003] Lightweight steel structures used on the roofs of factories, warehouses, etc. are usually I-beams with multiple connecting steel plates with circular holes welded at equal distances on the upper end face (see Figure 8 ), when welding the I-beam and the connecting steel plate in the above-mentioned lightweight steel structure, it is necessary to place the I-beam in a specified position, fix the connecting steel plate manually or by clamping it, and make it fit the upper end face of the I-beam, and then weld and fix the connection between the connecting steel plate and the upper end face of the I-beam by an arc welding machine.

[0004] The existing welding equipment has the following defects and technical problems when welding I-beams and connecting steel plates: 1. In the current welding process, the manual placement of the connecting steel plate causes the connecting steel plate and the upper end surface of the I-beam to tilt left and right or up and down. When the connecting steel plate and the upper end surface of the I-beam are tilted, not only will the weld position of the weld be deviated, causing welding defects such as pores and slag inclusions in the weld, affecting the welding quality, but even the tilt angle of the connecting steel plate will be too large, resulting in the inability to weld. In addition, the tilted connecting steel plate causes other components that fix the roof of the house (such as fixed shafts and steel pipes, etc.) to be unable to pass through the circular holes of the connecting steel plate, thereby affecting the structural strength of the entire building; 2. Before each welding of the connecting steel plate, the operator needs to measure and correct the welding position of the connecting steel plate, but it is impossible to ensure that the spacing between multiple connecting steel plates is the same, which not only increases the welding time and increases the production cost, but also causes other fixed components that need to pass through the circular holes of the connecting steel plate (such as wires and pipes, etc.) to encounter difficulties during installation due to the unequal placement of the welded connecting steel plates. , Require additional adjustments or modifications, increase the difficulty and cost of installation.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1 and Figure 2 As shown, a lightweight steel structure welding device includes a base 10, the U-shaped base 10 is hollow inside and the opening is facing upward, the inner cavity of the base 10 is fixedly provided with a driving mechanism 2, the upper end surfaces of the two vertical sections of the base 10 are fixedly provided with side plates 11, and the upper end surfaces of the two side plates 11 are fixedly provided with positioning plates 12.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first clamping mechanism 3 is provided on the upper end surface of the horizontal section of the base 10 for sliding back and forth. The first clamping mechanism 3 includes two first movable plates 31 which are symmetrically arranged front to back and have a cavity inside. An external clamping unit 32 is provided on the two first movable plates 31. A sliding groove 14 is provided through the upper end surfaces of the two side plates 11. An electric slider 13 is provided on the side of the two side plates 11 away from the base 10 for sliding left and right. The two electric sliders 13 are fixedly provided with a second clamping mechanism 4, and each first movable plate 31 is fixedly provided with an adjustment unit 34.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the second clamping mechanism 4 includes a fixing plate 41 with a cavity inside, and a U-shaped fixing plate 41 is fixedly provided on the upper end surfaces of the two electric sliders 13, and the U-shaped opening of the fixing plate 41 faces downward. A lifting unit 42 is provided on the lower end surface of the horizontal section of the fixing plate 41, and the lifting unit 42 includes a linkage plate 427 for vertically clamping the connecting steel plate 16, and positioning units 43 are provided on the opposite surfaces of the two vertical sections of the fixing plate 41.

[0035] It should be noted that square plates with multiple circular holes are welded and fixed to the left and right ends of the I-beam 50. In the initial state, the two first movable plates 31 and the corresponding external clamping units 32 are respectively located at the front and rear ends of the base 10. The operator places the I-beam 50 from top to bottom on the upper end surface of the horizontal section of the base 10. During operation, the two electric sliders 13 then work to drive the second clamping mechanism 4 to slide to the right. The positioning unit 43 is used to make the second clamping mechanism 4 stop sliding after moving a certain distance. The positioning unit 43 can control the welding position of the connecting steel plate 16 so that the spacing between multiple connecting steel plates 16 is the same, ensuring the uniformity and stability of the overall structure. Secondly, it provides an accurate installation position for other fixed components, which can avoid structural problems or safety hazards caused by improper installation position.

[0036] Subsequently, the staff operated the driving mechanism 2, which drove the two first movable plates 31 to move synchronously toward each other. The first movable plates 31 drove the outer clamping units 32 to synchronously clamp and fix the outer end faces of the left and right ends of the I-beam 50 and the left and right inner end faces of the front and rear ends, ensuring that the I-beam 50 and the connecting plate 16 remain stable during the welding process and avoid movement, thereby greatly improving the accuracy and quality of welding.

[0037] Then the staff placed the connecting steel plate between the lifting units 42, and then drove the lifting units 42 to move downward. During the downward movement of the lifting units 42, the connecting steel plate 16 was first clamped vertically by the linkage plate 427, and then the clamped connecting steel plate 16 was driven to move downward until the lower end surface of the connecting steel plate 16 was in contact with the upper end surface of the I-beam 50. The lifting units 42 can make the clamping plate 16 vertically in contact with the upper end surface of the I-beam 50, and keep them clamped during welding, which not only further improves the stability of welding and ensures product quality, but also keeps the connecting steel plate 16 and the I-beam 50 in a vertical state during welding, avoiding the problem of deviation in the weld position due to left-right tilting or up-and-down tilting of the I-beam 50 and the connecting steel plate 16 during welding, which affects the welding quality or even makes it impossible to weld.

[0038] like Figure 2 and Figure 3 As shown, the driving mechanism 2 includes a first reciprocating screw 21 with an axis extending from front to back, the inner cavity of the base 10 is rotatably provided with the first reciprocating screw 21, the first reciprocating screw 21 is connected to an external motor (not shown in the figure), and two first movable plates 31 are slidably provided on the first reciprocating screw 21, the first movable plate 31 is threadedly matched with the first reciprocating screw 21, and a driving gear 22 fixedly sleeved on the first reciprocating screw 21 is located on the front side of the first movable plate 31 at the front side, and two second reciprocating screws 23 symmetrically arranged on the inner cavity of the base 10 and extending from front to back are rotatably provided, and a driven gear 24 meshing with the driving gear 22 is fixedly sleeved on the two second reciprocating screws 23.

[0039] During operation, the external motor drives the first reciprocating screw 21 to rotate, so that the two first movable plates 31 on the front and rear sides slide back and forth on the first reciprocating screw 21 as the first reciprocating screw 21 rotates, and the first reciprocating screw 21 drives the driving gear 22 to rotate synchronously, and the driving gear 22 drives the two driven gears 24 on the front and rear sides to engage and rotate, so that the two driven gears 24 both drive the second reciprocating screw 23 to rotate synchronously, and the first clamping mechanism 3 is driven by the driving mechanism 2 to firmly clamp the I-beam 50 on the base 10, so as to facilitate the subsequent positioning and welding of the connecting steel plate 16 and the I-beam 50.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, the outer clamping unit 32 includes a bonding plate 322, and two front-to-back symmetrical bonding plates 322 are arranged between the two side plates 11 for sliding forward and backward. A clamping spring 323 is arranged between each bonding plate 322 and the corresponding first movable plate 31. An adjustment plate 321 is arranged in the inner cavity of each first movable plate 31 for sliding up and down. The adjustment plate 321 is a T-shaped plate. The front adjustment plate 321 is taken as an example for explanation. A plurality of positioning rods 324 with axes extending from front to back are fixedly arranged on the rear end face of the horizontal section of the front adjustment plate 321.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the outer clamping unit 32 also includes a second movable plate 331, each of the second reciprocating screw rods 23 is provided with two second movable plates 331 arranged symmetrically front and back, the second movable plates 331 and the second reciprocating screw rods 23 are threadedly matched, the upper end surface of each second movable plate 331 is fixedly provided with a sliding plate 332, and the sliding plate 332 is slidably arranged in the sliding groove 14 front and back, taking the right sliding plate 332 as an example for explanation, the left end surface of the right sliding plate 332 is fixedly provided with two spring rods distributed up and down and with the axis extending from right to left from top to bottom, and each of the spring rods is fixedly provided with a clamping plate 333, and the upper and lower end surfaces of the opposite sides of the two clamping plates 333 opposite to each other on the left and right are both inclined surfaces, and the two inclined surfaces on the same clamping plate 333 are symmetrical up and down, and the left side clamping plate 333 is taken as an example for explanation, and the upper side inclined surface of the left side clamping plate 333 is inclined downward from left to right.

[0042] During operation, when the staff puts the I-beam 50 into the upper end surface of the horizontal section of the base 10, the left and right sides of the lower end surface of the I-beam 50 are in contact with the inclined surfaces of the upper end surfaces of the plurality of clamping plates 333, so that each clamping plate 333 slides left and right and continuously compresses the spring rod. As the I-beam 50 continues to move downward, the clamping plate 333 moves to the side of the I-beam 50, so that the I-beam 50 can be placed on the upper end surface of the horizontal section of the base 10. At this time, after the clamping plate 333 moves to the position opposite to the vertical section of the I-beam, the spring rod is compressed and deformed to produce The elastic force causes the clamping plate 333 to reset, and the clamping plate 333 is pressed against the vertical section of the I-beam 50, while the clamping plate is pressed against the horizontal section of the I-beam 50. After the work is completed, the I-beam 50 is moved upward. In the process of the I-beam 50 moving upward, the left and right sides of the upper end surface of the I-beam 50 contact the inclined surfaces of the lower end surfaces of multiple clamping plates 333, so that each clamping plate 333 slides left and right and continuously compresses the spring, and the clamping plate 333 moves and staggers with the vertical section of the I-beam 50, so that the I-beam 50 is easily taken out from the upper end surface of the horizontal section of the base 10.

[0043] The external motor drives the two first moving plates 31 on the front and rear sides to slide forward and backward on the first reciprocating screw rod 21, so that the two first moving plates 31 both drive the clamping springs 323 to move, and the clamping springs 323 push the bonding plate 322 to slide between the two side plates 11 until the opposite surfaces of the two bonding plates 322 are in contact with the left and right ends of the I-beam 50, and gradually compress the clamping springs 323. The elastic force generated by the compression deformation of the clamping springs 323 acts on the bonding plates 322, so that the bonding plates 322 on the front and rear sides cooperate with each other to clamp and fix the I-beam 50. The movable plate 331 and the two second movable plates 331 on the rear side all slide back and forth on the second reciprocating screw 23 as the second reciprocating screw 23 rotates. Each second movable plate 331 drives the sliding plate 332 to move, and each sliding plate 332 drives the two clamping plates 333 to move synchronously until the multiple clamping plates 333 on the front and rear sides synchronously clamp and fix the left and right inner end surfaces of the front and rear sides of the I-beam 50, and cooperate with the clamping and fixation of the bonding plate 322 to keep the I-beam 50 stable during the welding process, thereby preventing the I-beam 50 from moving during welding, thereby greatly improving the welding accuracy and quality.

[0044] When the adjusting plate 321 gradually approaches the I-beam 50 with the bonding plate 322, the positioning rod 324 can pass through the circular holes of the square plate welded at both ends of the I-beam 50, so that the bonding plate 322 and the clamping spring 323 remain horizontal and stable when moving toward the I-beam 50, thereby improving the stability of the external clamping unit 32 during clamping.

[0045] like Figure 3 , Figure 4 and Figure 5As shown, the adjustment unit 34 includes a card block 341, and a plurality of front-to-back symmetrical card blocks 341 are fixedly arranged in the cavity of each of the first movable plates 31 at equal distances from top to bottom. The right card block 341 is taken as an example for explanation, and the lower end surface of the front card block 341 is inclined upward from right to left. Each adjustment plate 321 slides forward and backward and penetrates two left-right symmetrical and L-shaped control plates 342, and an adjustment spring 343 is commonly arranged between the lateral sections of the two control plates 342.

[0046] When working, the operator observes the height of the square plates welded at both ends of the I-beam 50, and then pinches the lateral sections of the two control plates 342 at the same time, so that the lateral sections of the two control plates 342 move toward each other, and continuously compresses the adjusting spring 343 until the longitudinal sections of the two control plates 342 slide into the adjusting plate 321 and are no longer clamped and fixed with the clamping block 341. Then, the operator slides the control plate 342 upward or downward according to adjusting the height of the positioning rod 324 and the corresponding circular hole, so that the control plate 342 drives the adjusting plate 321 and the positioning rod 324 to move synchronously, and ensures that the positioning rod 324 can pass through the circular hole of the square plate. Then, the control plate 342 is released, so that the adjusting spring 343 is reset and drives the longitudinal sections of the two control plates 342 to be clamped between multiple clamping blocks 341, fixing the positions of the adjusting plate 321 and the positioning rod 324, so that the positioning rod 324 guides the movement of the bonding plate 322 and the clamping spring 323 in the subsequent clamping and fixing, thereby ensuring the clamping stability of the outer clamping unit 32.

[0047] like Figure 2 , Figure 6 and Figure 7 As shown, the lifting unit 42 includes a piston rod 421 with an axis extending from top to bottom, the upper end surface of the fixed plate 41 is slidably penetrated by the piston rod 421, and the piston rod 421 is driven by an external cylinder (not shown in the figure) to move up and down, and a placement plate 422 is fixedly provided on the lower end surface of the piston rod 421, and a plurality of placement rods 423 with an axis extending from front to back are fixedly provided at equal intervals on the bottom of the front end surface of the placement plate 422, and a wedge plate 424 is fixedly provided on the top of the front end surface of the placement plate 422, and the upper end surface of the wedge plate 424 is inclined downward from back to front.

[0048] like Figure 3 , Figure 6 and Figure 7 As shown, the lifting unit 42 also includes a push plate 425, and the push plate 425 is set to slide forward and backward in the inner cavity of the fixed plate 41. The rear end face of the push plate 425 is inclined upward from front to back. Two push springs 426 are commonly arranged between the inner cavity of the fixed plate 41 and the push plate 425. A linkage plate 427 is fixedly arranged on the lower end face of the push plate 425, and a plurality of through grooves corresponding to the placement rod 423 are opened through the front side of the linkage plate 427.

[0049] During operation, in the initial state, the distance between the placement plate 422 and the linkage plate 427 is greater than the width of the connecting steel plate 16, which is convenient for the staff to place the connecting steel plate 16 on the placement plate 422, and the push plate 425 is squeezed by the inclined surface of the wedge plate 424, so that the push spring 426 is in a compressed state. The staff suspends the connecting steel plate 16 on the front side of the placement plate 422 through the placement rod 423, and then pushes the piston rod 421 downward through the external cylinder, and the piston rod 421 drives the placement plate 422 to move downward. The placing plate 422 moves downward, and the placing plate 422 drives the placing rods 423 and the connecting steel plate 16 to move downward synchronously. At the same time, the placing plate 422 drives the wedge plate 424 to move downward. Since the inclined surface of the push plate 425 contacts the inclined surface of the wedge plate 424, the push plate 425 is gradually pushed by the compressed push spring 426 and slides backward along the inclined surface of the wedge plate 424. The wedge plate 424 drives the linkage plate 427 to move backward synchronously, so that the linkage plate 427 passes through the placing rod 423 through the through slot, and the connecting steel plate 16 is connected to the connecting plate 16. The connecting steel plate 16 is vertically clamped and fixed between the placement plate 422 and the linkage plate 427. The lifting unit 42 can vertically clamp and fix the connecting steel plate 16. Then the placement plate 422 and the linkage plate 427 drive the vertically clamped and fixed connecting steel plate 16 to move downward until the lower end surface of the connecting steel plate 16 contacts the upper end surface of the I-beam 50. The lifting unit 42 can vertically clamp the connecting steel plate 16 and make it fit with the upper end surface of the I-beam 50. The I-beam 50 and the connection maintain a stable vertical angle during the welding process. To prevent welding defects such as pores and slag inclusions caused by the misalignment of the welding position due to the inclination of the connecting steel plate 16 and the I-beam 50, which affects the welding quality, keep the I-beam 50 vertical to the connecting steel plate 16 during welding, which helps to improve the welding accuracy and the strength of the welded joint. Other components that fix the roof of the house (such as fixed shafts and steel pipes, etc.) can smoothly pass through the circular holes of the connecting steel plates, thereby ensuring the structural strength of the entire building. Secondly, the connecting steel plate 16 remains clamped and fixed during welding, which further improves the stability during welding.

[0050] like Figure 3 , Figure 6 and Figure 7 As shown, the positioning unit 43 includes a translation plate 431 with a hollow interior, and a plurality of positioning grooves 15 are equidistantly provided on the upper end surface of the positioning plate 12 from front to back. A translation plate 431 is provided on the upper end surface of the positioning plate 12 to slide forward and backward, and the inner cavities of the two translation plates 431 are penetrated by a clamping plate 432 that slides up and down. The clamping plate 432 is a T-shaped plate, and a positioning spring 433 is provided between the upper end surface of the horizontal section of each clamping plate 432 and the inner cavity of the translation plate 431, and a reset plate 434 is hinged on the front and rear sides of the placement plate 422, and a reset spring 435 is provided between the lower end surface of each reset plate 434 and the placement plate 422.

[0051] When working, the two electric slides 13 drive the fixed plate 41 to move right synchronously, and the fixed plate 41 drives the translation plate 431 to move synchronously, so that the translation plate 431 slides on the upper end surface of the positioning plate 12. When it moves to a certain distance, so that the lower end surface of the clamping plate 432 corresponds to the positioning groove 15 opened on the positioning plate 12, the horizontal section of the clamping plate 432 is pushed downward by the compressed positioning spring 433, so that the vertical section of the clamping plate 432 moves downward and contacts with the reset plate 434. The clamping plate 434 drives the reset plate 434 to move downward synchronously and compress the reset spring 435. The lower end surface of the vertical section of the clamping plate 434 passes through the translation plate 431 until it contacts the inner wall of the positioning groove 15. Then the operator clamps and fixes the connecting steel plate 16 through the lifting unit 42 and completes the welding. Then, the piston rod 421 and the placement plate 422 are driven to reset and move upward through the external cylinder, and the placement plate 422 drives the two sides The reset plate 434 moves upward synchronously until the reset plate 434 contacts the lower end surface of the horizontal section of the clamping plate 432, so that the reset plate 434 gradually compresses the reset spring 435, and the reset plate 434 drives the clamping plate 432 to move upward synchronously, so that the lower end surface of the clamping plate 432 is separated from the positioning groove 15, and then the electric slider 13 works to drive the fixing plate 41 to continue to slide backward. The staff determines the welding positions of the multiple connecting steel plates 16 through the cooperation of the positioning unit 43 and the lifting unit 42, so that the multiple connecting steel plates 16 are equidistantly welded to the upper end surface of the I-beam 50 from front to back, so that the fixed components (such as wires and pipes, etc.) can pass through the circular holes of the multiple connecting steel plates 16 during installation, thereby reducing the difficulty of installation. Secondly, the positioning unit 43 saves the time of manual measurement and positioning of the welding position of the connecting steel plates 16, thereby improving production efficiency, and can also reduce errors in human operation and improve welding accuracy.
