Description

Technical Field

[0001] The present invention relates to the field of sheet metal part processing, and particularly to a welding and fixing device for sheet metal part processing. Background Art

[0002] Sheet metal parts are products processed by sheet metal technology, and we can't do without sheet metal parts everywhere in our lives. Sheet metal parts are made through filament power windings, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging, and water jet cutting. The main processes of sheet metal processing include shearing, bending and hemming, bending forming, welding, and riveting. However, when some existing welding machines perform the welding process, they need to weld between two sheet metal parts. When fixing the sheet metal parts, most of them are simply tightened by bolts, and the simple tightening is not tight enough. At the same time, it can only tighten sheet metal parts of one specification and is inconvenient to tighten sheet metal parts of different specifications as needed, seriously affecting the welding of sheet metal parts and thus reducing the use effect. Summary of the Invention

[0003] In view of the above situation, in order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a welding and fixing device for sheet metal part processing, and the advantages thereof solve the problems raised in the above background art.

[0004] The above technical object of the present invention is achieved through the following technical solutions:

[0005] A welding and fixing device for sheet metal part processing includes a base. A clamping groove is formed at the top of the base. A clamping assembly is arranged in the clamping groove. The clamping assembly includes fixed seats arranged on both sides of the clamping groove. A positive and negative thread screw rod is rotatably connected between the fixed seats. One end of the positive and negative thread screw rod extends outside the clamping groove. The extended end of the positive and negative thread screw rod is connected to a servo motor through a coupling. The outside of the positive and negative thread screw rod is matched with a first moving block and a second moving block. The bottoms of the first moving block and the second moving block are both slidably matched with the clamping groove. The tops of the first moving block and the second moving block are both vertically and fixedly connected with limiting plates. The tops of the limiting plates all extend outside the clamping groove. A bottom plate is arranged on the adjacent side of the extended ends of the limiting plates. The bottom plates are on the same horizontal line. Limiting grooves are formed on the top surfaces of the bottom plates. Limiting components are arranged in the limiting grooves.

[0006] By adopting the above technical solution, during operation, the operator places the sheet metal parts to be welded on the bottom plates on the adjacent sides of the limiting plates respectively. At this time, the welding areas of the sheet metal parts on the bottom plates are arranged facing each other. Then, the operator cooperates with the limiting components to limit and fix the sheet metal parts on the bottom plates respectively. Then, the operator starts the servo motor according to the operation requirements, drives the left - and - right - hand threaded screw to rotate and work. At this time, the first moving block and the second moving block on the left - and - right - hand threaded screw move towards each other in cooperation with the clamping grooves until the limiting plates on the first moving block and the second moving block and the sheet metal parts on the adjacent sides move towards each other to an appropriate distance. At this time, the sheet metal parts on the adjacent sides of the limiting plates move towards each other synchronously until the welding areas of the sheet metal parts move towards each other and fit together. At this time, the operator cooperates with other components to complete the welding work.

[0007] Further setting: The limiting component includes connecting seats arranged on both sides of the limiting groove. A left - and - right - hand threaded screw is rotatably connected between the connecting seats. One end of the left - and - right - hand threaded screw extends outside the limiting groove. A rocker is fixedly connected to the extending end of the left - and - right - hand threaded screw. The first limiting block and the second limiting block are matched and connected to the outside of the left - and - right - hand threaded screw. The bottoms of the first limiting block and the second limiting block are both slidably matched with the limiting groove. The tops of the first limiting block and the second limiting block both extend outside the limiting groove.

[0008] By adopting the above technical solution, during operation, the operator places the sheet metal parts to be welded on the bottom plates on the adjacent sides of the limiting plates respectively. At this time, the welding areas of the sheet metal parts on the bottom plates are arranged facing each other. Then, the operator respectively turns the rocker to drive the left - and - right - hand threaded screw to rotate and work. At this time, the first limiting block and the second limiting block on the left - and - right - hand threaded screw move towards each other in cooperation with the limiting groove to clamp, fix and limit the two sides of the sheet metal part.

[0009] Further setting: A protective pad is fixedly connected to the adjacent sides of the first limiting block and the second limiting block.

[0010] By adopting the above technical solution, when the first limiting block and the second limiting block cooperate with other components to move towards each other to clamp and fix the sheet metal part, the protective pad contacts the sheet metal part to play a protective role.

[0011] Further setting: The adjacent sides of the bottom plates all extend with material - supporting plates, and the material - supporting plates are on the same horizontal line as the bottom plates.

[0012] By adopting the above technical solution, the material - supporting plates play a role in supporting and holding the materials, ensuring the stability of the sheet metal parts during welding.

[0013] Further setting: Installation holes are all penetrated through the four - week top of the base, and installation bolts are threadedly connected in the installation holes.

[0014] By adopting the above technical solution, through the cooperation of the mounting holes and the mounting bolts, it is convenient for the operator to install the entire device and ensure the stability of the entire device during operation.

[0015] Further setting: A shock pad is fixedly connected to the bottom of the base.

[0016] By adopting the above technical solution, when the base cooperates with other components to complete the installation and fixing operation, the shock pad plays a role of buffering and shock absorption.

[0017] In summary, the present invention has the following beneficial effects:

[0018] The present invention is equipped with a limiting component. During operation, the operator places the sheet metal parts to be welded on the bottom plate on adjacent sides of the limiting plate respectively. At this time, the welding areas of the sheet metal parts on the bottom plate are arranged facing each other. Then the operator rotates the rocker arms respectively to drive the rotation of the left and right-handed screw rods. At this time, the first limiting block and the second limiting block on the left and right-handed screw rods move towards each other in cooperation with the limiting grooves to clamp and fix the two sides of the sheet metal parts.

[0019] The present invention is equipped with a clamping component. After the sheet metal plate completes the fixed limiting operation, the operator turns on the servo motor according to the operation requirements to drive the rotation of the left and right-handed screw rods. At this time, the first moving block and the second moving block on the left and right-handed screw rods move towards each other in cooperation with the clamping grooves until the limiting plates on the first moving block and the second moving block move to a suitable distance facing each other. At this time, the sheet metal parts on adjacent sides of the limiting plates move towards each other synchronously until the welding areas of the sheet metal parts move towards each other and fit together. At this time, the operator cooperates with other components to complete the welding work. BRIEF DESCRIPTION OF THE DRAWINGS
