Description

Technical Field

[0001] This invention relates to the field of H-beam processing equipment technology, specifically to an adjustable-height H-beam assembly machine. Background Technology

[0002] H-beams, as a type of steel with a reasonable cross-section and excellent load-bearing capacity, are widely used in various fields such as construction engineering, bridge construction, machinery manufacturing, and steel structure workshops. Their production efficiency and assembly quality directly affect the safety and economy of downstream projects. As the core equipment on the H-beam production line, the assembly machine is mainly responsible for the precise alignment, clamping, assembly, and spot welding of the web and flanges. It is a key link in ensuring the subsequent welding quality of H-beams and improving production efficiency.

[0003] Currently, H-beam erecting machines on the market are mainly divided into two categories: fixed-height type and simple adjustable type. Among them, the fixed-height erecting machine has a simple structure and low cost, but its height is fixed and it can only be used to assemble H-beams of a single specification or a narrow range of specifications. When it is necessary to process H-beams with different web heights, it is necessary to replace the equipment or make major modifications to the frame, which not only increases production costs but also seriously affects production efficiency, and cannot meet the diversified and multi-specification production needs of small and medium-sized steel structure processing plants.

[0004] While existing simple adjustable assembly machines can achieve height adjustment, the lifting mechanisms mostly use single-side drive or simple hydraulic lifting, resulting in poor synchronization and problems such as tilting and jamming during lifting. This makes it difficult to guarantee assembly accuracy, and the verticality and alignment deviation between the web plate and the wing plate exceed the process requirements. Furthermore, the lifting mechanism has poor linkage with the positioning, clamping, conveying, and spot welding mechanisms, requiring manual readjustment of the positions of each mechanism after height adjustment, which is cumbersome and further reduces production efficiency.

[0005] With the rapid development of the steel structure industry, the market demand for H-beams is becoming increasingly diversified, ranging from small H-beams (web height around 100mm) to heavy-duty H-beams (web height over 1500mm). Simultaneously, the requirements for assembly accuracy, production efficiency, operational safety, and equipment versatility are constantly increasing. The existing assembly machines' technical shortcomings are no longer adequate to meet the industry's development needs. Therefore, developing an adjustable-height H-beam assembly machine has become an urgent need to address current industry pain points and improve the quality and efficiency of H-beam production.

[0011] As a preferred embodiment of the present invention, a rail is fixedly connected to the inner side of the support rod; and the rail is provided with first holes that are evenly spaced and penetrated at equal intervals. A control board is fixedly connected to the outside of the frame pole, and a first electric cylinder is fixedly embedded in the control board at equal intervals.

[0012] The four corners of the pressure block are symmetrically fixed with U-shaped rail sleeves, and the rail sleeves are slidably connected to the rails. The upper and lower end faces of the rail sleeve are respectively fixedly connected with gaskets.

[0013] The lower surface of the middle part of the pressure block is provided with moving grooves on both sides. A second screw is rotatably inserted in the moving groove.

[0014] As a preferred embodiment of the present invention, the positioning mechanism includes columns symmetrically arranged on both sides of the conveyor plate, and the columns are fixed to the base plate.

A clamping wheel is movably hinged to the end of the wheel frame through a rotating shaft. The clamping roller is located between two adjacent conveying rollers.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) An adjustable height H-beam assembly machine, wherein the gantry frame assembly is provided with a positioning mechanism for positioning the lower wing plate on both the front and rear sides, and the clamping wheel of the positioning mechanism is located between two adjacent conveying rollers. By adjusting the second electric cylinder, the clamping wheel is made to fit against the side of the lower wing plate. The two positioning mechanisms simultaneously position the lower wing plate from both the front and rear sides of the gantry frame assembly, thereby ensuring the absolute positioning of the lower wing plate during welding, improving the positional accuracy of the lower wing plate, and laying the foundation for welding accuracy.

[0016] (2) An adjustable height H-beam erecting machine, by extending the second cylinder, allows the pressure block to slide down along the frame rod through the connection of the rail sleeve and the rail. By symmetrically distributing the rail sleeves at the four corners of the pressure block to correspond to the rail, the vertical lifting and lowering of the pressure block is ensured, reducing the possibility of offset and lateral sway when the pressure block moves, and improving the moving accuracy of the pressure block.

[0017] (3) An adjustable height H-beam assembly machine, which starts a third motor to drive the second screw to rotate, and then adjusts the position of the moving plate in the moving slot, and adjusts the distance between the two clamps by driving the moving frame, so that the clamps on both sides fit the two sides of the upper steel piece, thereby aligning the upper steel piece and ensuring the docking accuracy.

[0018] (4) An adjustable height H-beam assembly machine, through the adjustable performance of the jacket, can bring the distance between the two jackets closer when welding the web and the lower flange. On the basis of the pressure roller, the jacket straightens the web from both sides. When welding the web and the upper flange, the distance between the jackets is readjusted to match the width adjustment distance of the upper flange. Thus, both the web and the upper flange can be aligned using the pressure holding mechanism, improving the adaptability of the structure alignment.

[0019] (5) An adjustable height H-beam erecting machine, by pushing the inner block inward with the first electric cylinder, thereby driving the first hole column, spring and second hole column to move inward synchronously, thereby causing the second hole column not covered by the rail sleeve to extend out of the first hole, and the spring of the rail sleeve covered part to be compressed; thereby locking the position of the rail sleeve by the partially extended second hole column, thereby locking the position of the pressure block, reducing the risk of the pressure block falling off and improving the safety of use.

[0020] (6) An adjustable height H-beam assembly machine, by incorporating a sensor in the second hole column, can reasonably record which second hole columns protrude and which second hole columns do not protrude after the pressure block is in place, and the second hole columns that do not protrude can reflect the true position of the pressure block, thereby detecting the lifting height of the pressure block. By transmitting the signal to the controller, the height data of the pressure block can be recorded, timely self-checking is performed, and deviations can be easily corrected.

[0021] (7) An adjustable height H-beam assembly machine, wherein the pressing mechanism presses the upper part of the steel part, and the alignment component assists in the side work of the steel part; the alignment component is slidably mounted on the frame through a first cylinder, a second motor and a slider, so that the specific position of the alignment component can be controlled by the first motor, and the position to be flexibly adjusted can be adjusted to improve the flexibility of auxiliary welding.

[0022] (8) An adjustable height H-beam assembly machine, wherein a first ball bearing that fits the web is horizontally hinged to the end of the ball rod through a ball sleeve, so that the first ball bearing fits the web and is aligned in the correct position. At the same time, the movement of the web can be converted into the rolling of the first ball bearing, reducing the friction between the web and the first ball bearing. Similarly, the friction between the flange and the second ball bearing is reduced, thus reasonably protecting the steel parts and reducing the damage rate of the steel parts during welding.

[0023] (9) An adjustable height H-beam assembly machine, wherein a second ball bearing that fits the wing plate is vertically hinged to the end of the ball rod through a ball sleeve, and is raised and lowered in conjunction with the lifting mechanism; when welding the web plate and the lower wing plate, the lower wing plate is raised by a hydraulic cylinder, so that the second ball bearing fits the lower wing plate downwards, and the first ball bearing fits the web plate inwards by extending the first cylinder, so that the two sets of steel parts can be simultaneously positioned by the alignment component, thereby further improving the welding quality.

[0024] (10) An adjustable height H-beam assembly machine, when welding the web and the upper wing plate, firstly rotates the second ball by 180 degrees by the second motor, lowers the lower wing plate by the hydraulic cylinder, so that the second ball fits the upper wing plate, and then the second motor can make the alignment component still limit the two sets of steel parts at the same time, thereby improving the fullness of the alignment component's limit.

[0029] The two brackets 201 have a first sliding groove 202 on their opposite sides and a second sliding groove 203 on their opposite back sides. The first sliding groove 202 and the second sliding groove 203 are aligned and connected. The opposite back sides of the two brackets 201 are fixedly connected to a sliding frame 204 corresponding to the second sliding groove 203.

The ends of the first electric cylinder 306 are fixedly connected to an inner block 308 that is adapted to the sliding inner groove 307. The inner side of the inner block 308 is fixedly connected to a first post 310 that is adapted to the insertion into the second hole 309. The inner end of the first post 310 is fixedly connected to a spring 311. The inner end of the spring 311 is fixedly connected to a second post 312 that is adapted to the insertion into the first hole 304. Initially, the first electric cylinder 306 retracts, the inner block 308 moves closer to the outside, and the second post 312 is completely retracted into the first hole 304; when the first electric cylinder 306 is activated to extend, it pushes the inner block 308 inward, which can push the second post 312 out of the first hole 304 by pushing the first post 310 and the spring 311 inward.

[0033] The four corners of the pressure block 401 are symmetrically fixed with U-shaped rail sleeves 405, and the rail sleeves 405 are corresponding to the sliding rails 303. The upper and lower end faces of the rail sleeve 405 are respectively fixedly connected with the gasket 406.

[0034] The lower surface of the middle part of the pressure block 401 is provided with moving grooves 407 on both sides. A second screw 408 is rotatably inserted in the moving groove 407. A third motor 409 that is fixed to the pressure block 401 is installed at the outer end of the second screw 408. The third motor 409 is adapted between two support rods 302 on the same side. A movable plate 410 is fitted into the movable groove 407, and the movable plate 410 is threaded onto the second screw 408; the lower end of the movable plate 410 is fixedly connected to a movable frame 411 that is movably connected to the pressure roller 404, and the movable frame 411 is located inside the side plate 403; the inner side of the movable frame 411 is rotatably connected to a sleeve 412 that is movably connected to the pressure roller 404, and the inner end face of the sleeve 412 is coated with a wear-resistant coating.

[0035] The positioning mechanism 5 includes columns 501 symmetrically arranged on both sides of the conveyor plate 103, and the columns 501 are fixed to the base plate 101. A second electric cylinder 502 is fixedly embedded on the opposite face of the two columns 501. A wheel frame 503 is fixedly connected to the end of the second electric cylinder 502. A clamping wheel 504 is movably hinged to the end of the wheel frame 503 through a rotating shaft. The clamping roller 504 is located between two adjacent conveying rollers 104.

[0036] The working principle of this invention is as follows: The steel parts are conveyed by conveyor rollers 104, and the lower flange of the steel parts is in contact with the conveyor rollers 104. Alignment mechanisms 5 for aligning the lower flange are set on both the front and rear sides of the gantry assembly, and the clamping wheels 504 of the alignment mechanism 5 are located between two adjacent conveyor rollers 104. By adjusting the second electric cylinder 502, the clamping wheels 504 are made to fit against the side of the lower flange. The two alignment mechanisms 5 are aligned with the lower flange from the front and rear sides of the gantry assembly simultaneously, thereby ensuring the absolute alignment of the lower flange during welding, improving the positional accuracy of the lower flange, and laying the foundation for welding accuracy.

[0037] By extending the second cylinder 402, the pressure block 401 slides down along the frame rod 302 through the connection of the rail sleeve 405 and the rail 303. By symmetrically distributing the rail sleeve 405 at the four corners of the pressure block 401 corresponding to the rail 303, the vertical lifting and lowering of the pressure block 401 is ensured, reducing the possibility of offset and lateral sway when the pressure block 401 moves, and improving the moving accuracy of the pressure block 401.

[0038] By moving the pressure block 401 downwards, the pressure roller 404 presses against the upper steel part. Through the symmetrically fitted sleeves 412 on both sides of the pressure roller 404, after the pressure roller 404 presses against the upper steel part, the third motor 409 is started to drive the second screw 408 to rotate. Then, by adjusting the position of the moving plate 410 in the moving groove 407, the distance between the two sleeves 412 is adjusted by driving the moving frame 411, so that the sleeves 412 on both sides are set to fit against the two sides of the upper steel part, thereby aligning the upper steel part and ensuring the docking accuracy.

[0039] By adjusting the performance of the sleeve 412, the distance between the two sleeves 412 can be brought closer when welding the web and the lower flange. With the pressure of the pressure roller 404, the sleeves 412 straighten the web from both sides. When welding the web and the upper flange, the distance between the sleeves 412 can be readjusted to match the width adjustment distance of the upper flange. Thus, both the web and the upper flange can be aligned using the pressure holding mechanism 4, improving the adaptability of the structural alignment.

[0040] The pressure block 401 is moved by the adjustment of the second cylinder 402, and is simultaneously controlled by the rail 303 and the rail sleeve 405. Therefore, a second post 312 is set on the support rod 302. Before and after the operation of moving the pressure block 401 by the second cylinder 402, the second post 312 needs to be operated. When the pressure block 401 is moved into place, the inner block 308 is pushed inward by the first electric cylinder 306, which in turn drives the first post 310, the spring 311 and the second post 312 to move inward synchronously. This causes the part of the second post 312 not covered by the rail sleeve 405 to protrude out of the first hole 304, and the spring 311 covered by the rail sleeve 405 is compressed. Then, the position of the rail sleeve 405 is locked by the partially protruding second post 312, which in turn locks the position of the pressure block 401, reducing the risk of the pressure block 401 falling off and improving the safety of use.

[0041] By incorporating a sensor in the second post 312, it is possible to accurately record which second posts 312 protrude and which do not protrude after the pressure block 401 is in position. The non-protruding second posts 312 can reflect the true position of the pressure block 401, thereby detecting the lifting height of the pressure block 401. By transmitting the signal to the controller, the height data of the pressure block 401 can be recorded, enabling timely self-checking and easy correction of deviations.

[0042] The holding mechanism 4 holds the steel part on the upper part, while the alignment component assists in the work on the side of the steel part. The alignment component is slidably mounted on the bracket 201 through the first cylinder 207, the second motor 211 and the slider 212, so that the specific position of the alignment component can be controlled by the first motor 206, and the position to be flexibly adjusted can be adjusted to the required position, thereby improving the flexibility of auxiliary welding.

[0043] By horizontally hinged to the end of the cue stick 208 via a ball sleeve, the first ball 209 is aligned with the web plate, thus ensuring that the first ball 209 is aligned with the web plate. At the same time, the movement of the web plate can be converted into the rolling of the first ball 209, reducing the friction between the web plate and the first ball 209. Similarly, the friction between the flange and the second ball 210 is reduced, thus protecting the steel parts and reducing the damage rate of the steel parts during welding.

[0044] Meanwhile, a second ball bearing 210 that fits the wing plate is vertically hinged to the end of the cue stick 208 via a ball sleeve, which works in conjunction with the lifting mechanism 1. When welding the web and the lower wing plate, the lower wing plate is lifted by the hydraulic cylinder 102, so that the second ball bearing 210 fits the lower wing plate downwards. The first ball bearing 209 fits the web plate inwards by extending the first cylinder 207. Thus, the alignment component can simultaneously limit the two sets of steel parts, further improving the welding quality.

[0045] When welding the web and the upper flange, the second ball bearing 210 is first rotated 180 degrees by the second motor 211, and the lower flange is lowered by the hydraulic cylinder 102 so that the second ball bearing 210 fits against the upper flange. Then, the second motor 211 can make the alignment component still limit the two sets of steel parts at the same time, improving the fullness of the alignment component's limit.
