An H-beam steel assembly fixture

Abstract

This utility model discloses an H-beam assembly fixture, relating to the field of H-beam production and processing. It includes a base, a stop seat, a sorting mechanism, and two sets of flange plate positioning mechanisms. A support seat for placing the web plate is fixedly installed on the top of the base. The stop seat is fixedly installed at one end of the base, with its side contacting the web plate. The two sets of flange plate positioning mechanisms are symmetrically arranged on both sides of the support seat. Each flange plate positioning mechanism includes a bearing part, a pushing component, and a second hydraulic rod. The bearing part is integrally connected from an L-shaped plate and a long vertical plate. This utility model, by suspending the flange plate into the storage cavity of the bearing part and controlling the extension of the second hydraulic rod, moves the clamping plate towards the flange plate, causing multiple pulleys to contact the flange plate, thereby clamping and positioning the flange plate between the pulleys and the L-shaped plate. This significantly improves the stability of the flange plate during assembly. Furthermore, the friction is small when the pulleys initially contact the flange plate, making it easier to align the flange plate.

Description

Technical Field

[0001] This utility model belongs to the field of H-beam steel production and processing, and specifically relates to an H-beam steel assembly tooling. Background Technology

[0002] In the field of steel structure manufacturing, H-beams are the main load-bearing components, and their assembly accuracy directly affects the welding quality and structural performance.

[0003] For example, Chinese patent CN209579317U discloses an H-beam assembly machine, which includes a base and a gantry. The gantry is equipped with an upper wing plate clamping wheel and a first cylinder that drives the upper wing plate clamping wheel to slide along the thickness direction of the web plate. A sliding groove is provided on the side wall of the gantry. The length direction of the sliding groove is arranged in the vertical direction. A sliding seat is provided in the sliding groove. The sliding seat slides and engages with the sliding groove. An mounting block is provided on the side wall of the sliding seat. A first lead screw is rotatably connected to the side wall of the gantry. The axial direction of the first lead screw is parallel to the length direction of the sliding groove.

[0004] Because H-beams have a certain length, relying solely on a small number of web clamping wheels, upper flange clamping wheels, and lower flange clamping wheels to perform point contact clamping on the flanges and webs of the H-beam results in insufficient stability, poor positioning effect, and an inability to adjust the relative position of the webs and flanges during assembly, leading to problems such as misalignment and uneven gaps during assembly.

[0005] Therefore, we propose an H-beam steel assembly fixture to solve the above problems. Utility Model Content

[0006] In response to the problem that the H-beam erecting machine relies on only a small number of web clamping wheels, upper flange clamping wheels, and lower flange clamping wheels to perform point contact clamping on the flanges and web of the H-beam, resulting in insufficient stability and poor positioning effect, this utility model provides an H-beam erecting fixture.

[0007] The solution adopted by this utility model to solve its technical problem is: an H-beam steel assembly fixture, including a base, a stop seat, an arranging mechanism and two sets of flange plate positioning mechanisms, wherein a support seat for placing the web plate is fixedly installed on the top of the base.

[0008] The stop seat is fixedly installed at one end of the base, with its side contacting the web plate;

[0009] Two sets of flange plate positioning mechanisms are symmetrically arranged on both sides of the support seat. The flange plate positioning mechanism includes a bearing part, a pushing component and a hydraulic rod. The bearing part is integrally connected by an L-shaped plate and a long vertical plate. The top of the L-shaped plate is lower than the lower surface of the web plate. A storage cavity for placing the flange plate is formed between the L-shaped plate and the long vertical plate.

[0010] The clamping plate is set in the storage cavity and corresponds to the flange plate. The hydraulic rod two is fixedly installed on the outer side of the long vertical plate, and its piston rod passes through the long vertical plate and is fixedly connected to the clamping plate.

[0011] The pushing component is mounted on top of the base and connected to the long vertical plate to drive the load-bearing part to move back and forth;

[0012] The sorting mechanism includes a fixed base, a push plate, and a drive component. The fixed base is fixedly installed at the other end of the base. The push plate contacts the web plate and the flange plate. The drive component is installed on the fixed base and connected to the push plate to drive the push plate to move left and right.

[0013] Preferably, multiple fixing sleeves are installed on the long vertical plate, and guide rods are provided inside the fixing sleeves, with the inner ends of the guide rods fixedly connected to the clamping plate.

[0014] Preferably, multiple sets of pulleys are fixedly installed on the side of the clamp plate near the flange plate.

[0015] Preferably, the pushing assembly includes two mounting seats fixedly mounted on the top of the base, and a hydraulic rod three is fixedly mounted on the mounting seats. The piston rod of the hydraulic rod three passes through the mounting seat and is connected to the long vertical plate.

[0016] Preferably, a plurality of sliding blocks are fixedly installed at the bottom of the bearing portion, the sliding blocks are arranged on the guide rail, and the guide rail is fixedly installed on the top of the base.

[0017] Preferably, the driving component is a hydraulic rod one mounted on the side of the fixed seat, and the piston rod of the hydraulic rod one passes through the fixed seat and is connected to the push plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model suspends the flange plate into the storage cavity of the bearing part, and controls the extension of the hydraulic rod two to move the clamping plate toward the flange plate, so that multiple pulleys come into contact with the flange plate, and then clamps and positions the flange plate between the pulleys and the L-shaped plate, which significantly improves the stability of the flange plate during the assembly process. In addition, when the pulleys and the flange plate initially come into contact, the friction is small, making it easier for the flange plate to be aligned.

[0020] 2. This utility model controls the synchronous extension of the three hydraulic rods on both sides to drive the load-bearing parts on both sides to move closer to each other, flexibly adjusting the mating gap between the flange plate and the web plate to ensure uniform assembly gap.

[0021] 3. This utility model controls the synchronous extension of two hydraulic rods to make the push plate contact the web plate and the tail of the two flange plates, and pushes the ends of the web plate and the two flange plates to contact the stop seat, thereby aligning the web plate and the two flange plates and correcting the misalignment problem of the web plate and the two flange plates in real time, ensuring the accuracy and quality of H-beam assembly.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1-2 This utility model provides a technical solution for an H-beam steel assembly fixture:

[0027] Example 1:

[0028] according to Figure 1 and Figure 2 As shown, it includes a base 1, a stop seat 2, an organizing mechanism, and two sets of flange plate positioning mechanisms. A support seat 7 for placing the web plate is fixedly installed on the top of the base 1.

[0029] The stop seat 2 is fixedly installed at one end of the base 1, and its side is in contact with the web plate.

[0030] Two sets of flange plate positioning mechanisms are symmetrically arranged on both sides of the support seat 7. The flange plate positioning mechanism includes a bearing part 4, a pushing component and a hydraulic rod 53. The bearing part 4 is integrally connected by an L-shaped plate and a long vertical plate. The top of the L-shaped plate is lower than the lower surface of the web plate. A storage cavity for placing the flange plate is formed between the L-shaped plate and the long vertical plate.

[0031] The clamping plate 54 is set in the storage cavity and corresponds to the flange plate. Multiple sets of pulleys 55 are fixedly installed on the side of the clamping plate 54 near the flange plate. When the pulleys 55 initially contact the flange plate, the friction is small, making it easier for the flange plate to be aligned.

[0032] Hydraulic rod 53 is fixedly installed on the outer side of the long vertical plate. Its piston rod passes through the long vertical plate and is fixedly connected to clamping plate 54. By controlling the extension of hydraulic rod 53, clamping plate 54 moves towards flange plate, so that multiple pulleys 55 contact flange plate, thereby clamping and positioning flange plate between pulleys 55 and L-shaped plate, significantly improving the stability of flange plate during assembly. Multiple fixing sleeves 52 are installed on the long vertical plate. Guide rods 51 are set inside the fixing sleeves 52. The inner end of guide rod 51 is fixedly connected to clamping plate 54. Guide rod 51 and fixing sleeve 52 cooperate to ensure linear movement of clamping plate 54, prevent hydraulic rod 53 from being subjected to uneven load, and extend the service life of hydraulic rod 53.

[0033] The pushing assembly includes two mounting seats 62 fixedly installed on the top of the base 1. Hydraulic rods 61 are fixedly installed on the mounting seats 62. The piston rods of the hydraulic rods 61 pass through the mounting seats 62 and are connected to the long vertical plate. By controlling the synchronous extension of the hydraulic rods 61 on both sides, the bearing parts 4 on both sides are driven to move closer to each other, flexibly adjusting the mating gap between the flange and the web to ensure uniform assembly gap.

[0034] The sorting mechanism includes a fixed seat 32, a push plate 31, and two drive components. The fixed seat 32 is fixedly installed at the other end of the base 1. The push plate 31 contacts the web and flanges. The drive component is a hydraulic rod 33 installed on the side of the fixed seat 32. The piston rod of the hydraulic rod 33 passes through the fixed seat 32 and is connected to the push plate 31. By controlling the synchronous extension of the two hydraulic rods 33, the push plate 31 contacts the tail of the web and the two flanges, and pushes the ends of the web and the two flanges to contact the stop seat 2, sorting the web and the two flanges, correcting the misalignment of the web and the two flanges in real time, and ensuring the accuracy and quality of the H-beam assembly.

[0035] In practical use, the H-beam steel assembly fixture of this utility model first hoists the web plate to the top of the support seat 7, then hoists the left flange plate into the storage cavity of the corresponding bearing part 4, and by controlling the extension of the hydraulic rod 53, the clamping plate 54 moves towards the flange plate, so that multiple pulleys 55 contact the flange plate to initially position the flange plate, and then the right flange plate is hoisted and positioned.

[0036] Control the synchronous extension of the two hydraulic rods 33 to make the push plate 31 contact the web plate and the tail of the two flange plates, and push the ends of the web plate and the two flange plates to contact the stop seat 2 to tidy up the web plate and the two flange plates. Then control the extension of the two hydraulic cylinders on both sides again to clamp and position the flange plates between the pulley 55 and the L-shaped plate.

[0037] Finally, the synchronous extension of the hydraulic rods 361 on both sides is controlled to drive the bearing parts 4 on both sides to move closer to each other, flexibly adjusting the mating gap between the flange plate and the web plate to ensure uniform assembly gap, so that workers can weld the flange plate and the web plate.

[0038] Example 2:

[0039] Based on Example 1, such as Figure 1 and Figure 2 As shown, multiple sliding blocks 63 are fixedly installed at the bottom of the bearing part 4. The sliding blocks 63 are set on the guide rail 64, which is fixedly installed on the top of the base 1 to support and guide the bearing part 4, thereby improving the stability of the bearing part 4 when it moves back and forth.
