Description

Technical Field

[0001] The utility model relates to the technical field of H-beam welding fixtures, in particular to an H-beam auxiliary welding fixture. Background Art

[0002] When manually welding and assembling H-beams in a factory, a clamp is required to clamp and limit the web and flange plates of the H-beams to prevent them from sliding out of position during welding.

[0003] The clamp currently used for welding and assembling the web and flange of H-shaped steel in the factory mainly consists of a fixing sleeve, a screw installed in the middle of the upper end of the fixing sleeve, and a pressure plate installed at the clamping end of the screw. When used, the clamp of this structure is mainly used to press the web and flange ends that have been pre-welded and positioned, and then further weld and reinforce the H-shaped steel web and flange by manual step-by-step welding. Although the web and flange can be clamped and limited in position during the H-shaped steel welding process under the action of the above clamp, the web and flange need to be spot-welded and positioned in advance during the clamping process, and then the web and flange of the H-shaped steel can be clamped with the help of the above clamp, resulting in an inconsistency in the welding process of the H-shaped steel and a relatively low welding efficiency. Summary of the Invention

[0004] (1) Technical issues to be resolved

[0005] The technical problem to be solved by the present invention is to provide an H-beam auxiliary welding fixture based on the current status of the existing technology, which can directly position and connect the web and flange plates, eliminating the spot welding positioning operation between the web and flange plates before clamping, making the H-beam welding process smoother and the welding efficiency higher.

[0006] (2) Technical solution

[0007] The utility model is implemented through the following technical scheme: the utility model proposes an H-shaped steel auxiliary welding fixture, including a support, a support box is installed in the middle of the upper end of the support, and a lifting and positioning mechanism is installed on the support box, and the upper end of the support is located on both sides of the support box and a two-way clamping mechanism is installed together, wherein the lifting and positioning mechanism includes an electric telescopic rod installed in the support box, a support plate installed on the telescopic part of the electric telescopic rod, guide columns symmetrically installed on both sides of the bottom end of the support plate, and laser lamps symmetrically installed on both side walls of the support plate, and the two-way clamping mechanism includes a slide groove opened in the middle of the upper end of the support, a two-way screw rod installed in the middle of the slide groove, a toothed splint installed at two sections of threaded portions with opposite rotation directions on the two-way screw rod, and a drive motor installed on one side wall of the support facing the two-way screw rod.

[0008] Furthermore, the guide posts are distributed in a row at the bottom end of the support plate, and the guide posts are welded to the support plate.

[0009] By adopting the above technical solution, it can be ensured that the guide column is reliably installed and fixed at the bottom end of the support plate.

[0010] Furthermore, the support box has a hollow structure at a position facing the guide post, and the guide post is in sliding cooperation with the support box.

[0011] By adopting the above technical solution, the cooperation between the guide column and the hollow portion on the support box can ensure the stable lifting of the support plate.

[0012] Furthermore, the support plate is located at the laser lamp and has a hollow structure, and the support plate is plugged into the laser lamp.

[0013] By adopting the above technical solution, the laser lamp will focus the light on one point after being powered on, so as to judge whether the edge of the web is aligned with the middle of the flange by irradiating the position on the flange used for H-beam processing.

[0014] Furthermore, the bidirectional screw rod passes through the toothed splint and is threadedly connected to the toothed splint, and the toothed splint is slidably matched with the sliding groove.

[0015] By adopting the above technical solution, after the bidirectional screw is rotated under the action of the driving motor, the toothed clamping plate will slide conveniently along the slide groove under the guidance of the thread transmission and the slide groove, so that the placed flange plate can be quickly tightened on both sides of the web.

[0016] Furthermore, an operation panel is installed on an outer wall of the support on one side of the drive motor, and the support is an inverted U-shaped structure.

[0017] By adopting the above technical solution, the support can provide an installation basis for the support box and the bidirectional clamping mechanism.

[0018] Furthermore, the operation panel is electrically connected to the drive motor, the electric telescopic rod and the laser light.

[0019] By adopting the above technical solution, the operation panel mainly controls the coordinated work of the drive motor, the electric telescopic rod and the laser light by controlling the on-off of the circuit.

[0020] (3) Beneficial effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In order to solve the problem that the clamp currently used for welding and assembling the web and flange of H-shaped steel in the factory is mainly composed of a fixing sleeve, a screw installed in the middle of the upper end of the fixing sleeve, and a pressure plate installed at the clamping end of the screw. When used, the clamp of this structure is mainly used to compress the web and flange ends that have been pre-welded and positioned, and then further weld and reinforce the H-shaped steel web and flange by manual step-by-step welding. Although the web and flange can be clamped and limited in position during the H-shaped steel welding process under the action of the above clamp, the web and flange need to be spot-welded and positioned in advance during the clamping process, and then the web and flange of the H-shaped steel can be clamped with the help of the above clamp, resulting in the problem that the welding process of the H-shaped steel is not continuous and the welding efficiency is relatively low. The web and flange plates of the H-shaped steel are then welded together by the present invention. The web is directly placed on the support plate, and the flange plates are vertically placed on both sides of the support plate. The web is then lifted with the help of the electric telescopic rod in the lifting and positioning mechanism, and the workers are ensured to quickly align the edge of the web with the marking line in the middle of the flange plate under the irradiation of the laser light, so as to achieve rapid alignment and positioning between the web and flange plates. Then, it is only necessary to drive the bidirectional screw to rotate under the action of the driving motor, and the toothed clamping plate can be used to clamp the web and flange plates in a limited position during the rotation of the bidirectional screw rod to ensure rapid welding between the floating plate and the flange plates. Since the above clamping method eliminates the operation of pre-spot welding and assembling the web and flange plates of the H-shaped steel, the entire welding process of the H-shaped steel is smoother and the welding efficiency is higher.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1-Figure 4 As shown, an H-beam auxiliary welding fixture in this embodiment includes a support 2, a support box 1 is installed in the middle of the upper end of the support 2, a lifting and positioning mechanism 5 is installed on the support box 1, and a two-way clamping mechanism 4 is installed on both sides of the upper end of the support 2 and the support box 1, wherein the lifting and positioning mechanism 5 includes an electric telescopic rod 503 installed in the support box 1, a support plate 501 installed at the telescopic part of the electric telescopic rod 503, guide columns 504 symmetrically installed on both sides of the bottom end of the support plate 501, and laser lamps 502 symmetrically installed on the two side walls of the support plate 501. When the laser lamp 502 is powered on, it will focus the light on one point so that it can be illuminated on the H-beam. The position of the processing flange plate is used to determine whether the edge of the web plate is aligned with the middle of the flange plate. The bidirectional clamping mechanism 4 includes a slide groove 404 opened in the middle of the upper end of the support 2, a bidirectional screw rod 401 installed in the middle of the slide groove 404, a toothed splint 403 installed at two sections of threaded parts with opposite rotation directions on the bidirectional screw rod 401, and a drive motor 402 installed on the side wall of the support 2 facing the bidirectional screw rod 401. After the bidirectional screw rod 401 rotates under the action of the driving motor 402, the toothed splint 403 will slide conveniently along the slide groove 404 under the guidance of the thread transmission and the slide groove 404, so that the placed flange plate can be quickly tightened to both sides of the web plate.

[0031] like Figure 1-Figure 4 As shown, in this embodiment, the guide columns 504 are distributed in a row at the bottom end of the support plate 501, and the guide columns 504 are welded to the support plate 501, which can ensure that the guide columns 504 are reliably installed and fixed at the bottom end of the support plate 501, and the support box 1 is opposite to the guide columns 504. The guide columns 504 slide in conjunction with the support box 1. The cooperation between the guide columns 504 and the hollow parts on the support box 1 can ensure the stable lifting of the support plate 501, and the support plate 501 is a hollow structure at the laser lamp 502. The support plate 501 is plugged into the laser lamp 502, and the bidirectional screw rod 401 passes through the toothed splint 403 and is threadedly connected to the toothed splint 403, and the toothed splint 403 slides in conjunction with the slide groove 404.

[0032] like Figure 1-Figure 4As shown, in this embodiment, an operation panel 3 is also installed on the outer wall of the support 2 on one side of the drive motor 402. The support 2 is an inverted U-shaped structure. The support 2 can provide an installation basis for the support box 1 and the bidirectional clamping mechanism 4. The operation panel 3 is electrically connected to the drive motor 402, the electric telescopic rod 503 and the laser light 502. The operation panel 3 mainly controls the coordinated work of the drive motor 402, the electric telescopic rod 503 and the laser light 502 by controlling the on and off of the circuit.

[0033] The specific implementation process of this embodiment is as follows: when it is necessary to assemble and weld the web and flange plates for H-shaped steel processing, first connect the clamp to an external power supply, and place the web and flange plates for H-shaped steel welding flat on the support plate 501. At the same time, place the flange plates for H-shaped steel welding vertically on both sides of the support plate 501. Then, use the electric telescopic rod 503 in the lifting and positioning mechanism 5 to lift the web, and under the illumination of the laser light 502, ensure that the staff quickly aligns the edge of the web with the marking line in the middle of the flange to achieve rapid alignment and positioning between the web and the flange. Then, it is only necessary to drive the bidirectional screw rod 401 to rotate under the action of the driving motor 402, and the toothed clamping plate 403 can be used to clamp and limit the web and flange plates during the rotation of the bidirectional screw rod 401 to ensure rapid welding between the floating plate and the flange. Since the above-mentioned clamping method eliminates the operation of pre-spot welding and assembling the web and flange plates for the H-shaped steel, the entire welding process of the H-shaped steel is smoother and the welding efficiency is higher.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
