Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal deformation correction, and in particular relates to a mechanism for correcting plate deformation and welding. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming (such as car bodies), etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called sheet metal parts. Sheet metal parts have the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good performance in large-scale mass production. They have been widely used in the fields of electronics, communications, automobile industry, medical equipment, etc. However, the high temperature generated during the welding of existing sheet metal parts will cause the sheet metal parts to deform. If the deformation is not corrected, it will cause defective sheet metal parts and increase production costs. Therefore, a mechanism for correcting plate deformation and welding is urgently needed to solve the above problems. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a mechanism for correcting plate deformation and welding.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A mechanism for correcting plate deformation and welding comprises a suspension mounting frame with welding devices on both sides, a base is installed at the bottom of the suspension mounting frame, a fixed base plate is installed at the bottom of the base, movable clamping mechanisms A are installed at both ends of the top of the suspension mounting frame, and movable clamping mechanisms B are installed between the movable clamping mechanisms A at both ends of the suspension mounting frame, the power output ends of the movable clamping mechanisms A and B are connected with pressure blocks, and the upper sides of the movable clamping mechanisms A and B are both installed with travel limit blocks.

[0006] It is further defined that a plurality of side limit blocks are installed on the front and rear sides of the surface of the base, and the plurality of side limit blocks are evenly arranged on both sides of the base, wherein the spacing between two adjacent side limit blocks is equal. Such a structural design has a limiting effect on both sides of the sheet metal.

[0007] It is further defined that the base is provided with a plurality of evenly arranged support blocks between the side limit blocks on the front and rear sides. Such a structural design is based on the actual deformation situation, and a reasonable profile is cut locally to ensure that the sheet metal part is deformed in place.

[0008] It is further defined that rectangular plugs are provided on the left and right sides of the base. Such a structural design prevents the sheet metal from deforming when it is subjected to a large pressing force by placing the rectangular plugs on both sides of the sheet metal.

[0009] It is further defined that a positioning pin is provided at the middle of the base. Such a structural design limits the freedom of the sheet metal part in two directions, and is assisted by a single-side side limit block to achieve the effect of preventing the sheet metal part from rotating.

[0010] The beneficial effects of the utility model are as follows: the utility model sets multiple support blocks, side limit blocks and rectangular plug blocks according to the deformation direction and deformation amount fed back in production; then sets cylinders of different cylinder diameters according to the deformation requirements, and the rear part of the cylinder body needs to have a stroke adjustment function to achieve different clamping amounts at different positions to achieve the correction effect, and this structure, on the basis of conventional limit, sets plug blocks and double side limit blocks at both ends of the rectangular cross-section, effectively determines the benchmark, and ensures the effectiveness of the benchmark during correction.

DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2As shown, a mechanism for correcting plate deformation and welding of the utility model comprises a suspension mounting frame 2 with welding devices 1 on both sides, a base 3 is installed at the bottom of the suspension mounting frame 2, a fixed base plate 4 is installed at the bottom of the base 3, movable clamping mechanisms A5 are installed at both ends of the top of the suspension mounting frame 2, and a movable clamping mechanism B6 is installed between the movable clamping mechanisms A5 at both ends of the suspension mounting frame 2, a pressure block 7 is connected to the power output end of the movable clamping mechanism A5 and the movable clamping mechanism B6, and a travel limit block 8 is installed on the upper side of the movable clamping mechanism A5 and the movable clamping mechanism B6.

[0018] Preferably, a plurality of side limit blocks 9 are installed on the front and rear sides of the surface of the base 3, and the plurality of side limit blocks 9 are evenly arranged on both sides of the base 3, wherein the spacing between two adjacent side limit blocks 9 is equal. Such a structural design has a limiting effect on both sides of the sheet metal. In fact, other installation structural shapes of the side limit blocks 9 can also be considered according to specific circumstances.

[0019] Preferably, the base 3 is provided with a plurality of evenly arranged support blocks 10 between the side limit blocks 9 on the front and rear sides. Such a structural design is based on the actual deformation situation, and a reasonable profile is cut locally to ensure that the sheet metal part is deformed in place. In fact, other installation structural shapes of the support blocks 10 can also be considered according to specific circumstances.

[0020] Preferably, rectangular plugs 11 are provided on the left and right sides of the base 3. Such a structural design prevents the sheet metal from deforming when it is subjected to a large pressing force by placing the rectangular plugs 11 on both sides of the sheet metal. In fact, other structural shapes of the rectangular plugs 11 can also be considered according to specific circumstances.

[0021] Preferably, a positioning pin 12 is provided in the middle of the base 3. Such a structural design limits the freedom of the sheet metal in two directions, and is assisted by the single-side side limit block 9 to achieve the effect of preventing the sheet metal from rotating. In fact, other structural shapes of the positioning pin 12 can also be considered according to specific circumstances.

[0022] In this embodiment, the sheet metal 13 with a partial weld seam previously welded is placed on the base 3, and side limit blocks 9 are arranged according to the actual deformation situation, and as close to the ends as possible at both ends to ensure the required size; and a group of side limit blocks 9 are added to resist the deformation of arc welding, and the support block 10 is used to locally cut out a reasonable profile according to the actual deformation situation to ensure that the sheet metal 13 is deformed in place, and the freedom of the sheet metal 13 in two directions is limited by the positioning pin 12, and the single-sided side limit block 9 is used to assist in achieving the effect of preventing the sheet metal 13 from rotating, and finally, rectangular plugs 11 are inserted at both ends of the sheet metal 13 to prevent the sheet metal 13 from deforming when subjected to a large clamping force, and then the active clamping mechanism A5 and the active clamping mechanism B6 are started, so that the active clamping mechanism A5 and the active clamping mechanism B6 push the pressing block 7 to press on the sheet metal 13, and then the welding work is carried out through the welding device 1, and the active clamping mechanism A5 and the active clamping mechanism B6 rise and reset after the welding is completed.

[0023] Among them, both the movable clamping mechanism A5 and the movable clamping mechanism B6 use cylinders. Because the deformation of the ends of the sheet metal part 13 is relatively large, the movable clamping mechanism A5 is placed at both ends, and the movable clamping mechanism B6 is placed at a position where the anti-deformation force does not need to be very large.

[0024] The travel of the active clamping mechanism A5 and the active clamping mechanism B6 can be adjusted through the travel limit block 8, so that it can be adjusted to cope with different deformations of the real object to meet the expected requirements. By analyzing the deformation of the sheet metal parts, cylinders with different cylinder diameters are set at the corresponding positions, and the air pressure is used to drive the adjustment to adjust the deformation of about 10mm. The body is low, the operation is simple, and the maintenance is easy to get started.

[0025] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
