Description

Technical Field

[0001] The utility model belongs to the technical field related to end plate welding, and in particular relates to a jig for preventing deformation of end plates of protective components during welding. Background Art

[0002] Structural components are the elements that constitute the load-bearing skeleton of the structure, including beams, columns, roof trusses, foundations, etc. In the field of structural functions, most components are welded steel structures. The component end plates are an important part of the components. For the component end plate welding process, the component end plates will be deformed after welding. There will be gaps in the end plates during installation, and high-strength bolts will not be tightened, resulting in the friction coefficient not meeting the design requirements, creating safety hazards. In order to reduce the impact of component end plate welding deformation on subsequent assembly, the component end plates need to be calibrated. The calibration cycle is long and the cost is high.

[0003] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] like Figures 1 to 4 As shown, a jig for protecting component end plates from welding deformation, a movable lock 1 and an anti-deformation strip 2, the movable lock 1 is installed at the two end positions of the component end plate 4, the movable lock 1 includes a lock upper clamp 5, a lock lower clamp 6 and a lock connecting end plate 7, the lock upper clamp 5 and the lock lower clamp 6 are parallel to each other, the outer end positions of the lock upper clamp 5 and the lock lower clamp 6 are fixedly connected by the lock connecting end plate 7, a threaded hole 10 is processed on the lock connecting end plate 7, a tightening adjustment screw 8 is installed in the threaded hole 10, an anti-deformation strip 2 is provided in the gap formed between the lock upper clamp 5 and the lock lower clamp 6, one side of the anti-deformation strip 2 is in contact with the outer side surface of the component end plate 4, and the setting of the anti-deformation strip 2 is used to enhance the overall anti-deformation ability of the component end plate 4.

[0024] The component end plate 4 is arranged at the end of the component body 3 , and the length of the anti-deformation strip 2 is greater than that of the component end plate 4 to ensure that the component end plate 4 is uniformly stressed in the length direction.

[0025] The upper and lower clamping plates 5 and 4 of the lock are both provided with corresponding clamping grooves 9. The clamping grooves 9 are L-shaped structures. The two ends of the component end plate 4 are located in the clamping grooves 9 to achieve the matching installation between the movable lock 1 and the component end plate 4.

[0026] The outer end of the compression adjustment screw 8 is provided with a T-shaped handle structure for easy rotation adjustment, without the need for a structural auxiliary wrench tool.

[0027] The anti-deformation strip 2 is placed on the lock lower clamping plate 6, and the end of the compression adjustment screw 8 away from the T-shaped handle is compressed and fixed to the outer side of the anti-deformation strip 2. The anti-deformation strip 2 and the component end plate 4 are compressed and fixed using the compression adjustment screw 8.

[0028] When a set of deformation protection jigs includes two movable lock buckles 1 and an anti-deformation bar 2 welded to the component end plate 4, multiple sets of deformation protection jigs can be used at one time.

[0029] The working principle of the present invention is as follows: when welding the component end plates 4 of the component main body 3, first determine the relative position of the component end plates 4 and the component main body 3, fix the relative position of the component end plates 4 and the component main body 3 by spot welding or auxiliary positioning devices, select and use one or more sets of deformation protection jigs according to the specifications of the component end plates 4, clamp the engaging grooves 9 of the movable lock 1 at the two end heads of the component end plates 4, place the anti-deformation strips 2 on the lower clamping plates 6 of the two locks, adjust the compression adjustment screws 8, and use the compression adjustment screws 8 to tighten the anti-deformation strips. The outer side of the strip 2 is pressed tightly, and the surface of the anti-deformation strip 2 corresponding to the compression adjustment screw 8 is in contact with the outer edge of the component end plate 4, which is used to enhance the overall structural strength and anti-deformation ability of the component end plate 4. After that, the component body 3 and the component end plate 4 are welded, which can effectively reduce the deformation of the component end plate 4 during the welding process. No correction is required after welding, which can effectively improve the welding efficiency and welding quality of the component end plate 4 and reduce the welding cost. At the same time, the welding deformation protection fixture is changed to a detachable structure design, which can be reused and has a low production cost.

[0030] When using one set of welding deformation protection fixtures, try to install them in the middle of the component end plate 4. When using two sets of welding deformation protection fixtures, try to install them symmetrically. When using multiple sets of deformation protection fixtures, try to set them at equal intervals to ensure the uniformity of the force on the component end plate 4, thereby increasing the anti-deformation ability of each position.

[0031] The jig for protecting the component end plate 4 from welding deformation of the present invention includes a movable lock buckle 1 and an anti-deformation bar 2. The movable lock buckle 1 is arranged at both ends of the anti-deformation bar 2. The anti-deformation bar 2 is used to fit in contact with the component end plate 4 to support the outer side of the component end plate 4, thereby reducing the deformation of the component end plate 4 during welding. The component end plate 4 welding deformation protection jig can be used in multiple groups according to welding requirements to meet the welding requirements of component end plates 4 of different specifications. The movable lock buckle 1 is fixedly installed by tightening the adjusting screw 8, which is convenient for disassembly and assembly.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
