Technical Field

[0001] This utility model relates to the field of door manufacturing technology, and in particular to a workbench for door welding production. Background Technology

[0002] In modern door manufacturing, especially in the production of aluminum alloy doors, welding between the four door frames is required. The welding process generates a lot of heat, which can cause the door frame to deform due to the increased heat. This deformation can lead to incorrect welding positions, affecting the final forming effect. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to propose a workbench for door welding production, so as to solve the problem that the door frame in the prior art will deform due to increased heat.

[0004] Based on the above objectives, this utility model provides a workbench for door welding production. The door frame to be welded is installed on the workbench for welding. The frame edge has two opposing protrusions, including a frame; a rigid tabletop, fixedly connected to the top of the frame, with a rectangular structure, made of a single steel plate, with a flat upper surface and limiting grooves around the upper surface, each limiting groove containing a positioning hole; a first limiting block, disposed in the limiting groove, with a threaded hole at the bottom, fixed to the positioning hole by a screw, and a limiting protrusion on the side, the lower surface of the limiting protrusion having a gap with the upper surface of the rigid tabletop, the gap thickness being greater than the thickness of the protrusions, the limiting protrusion inserting into the space between the two protrusions along the frame edge; the top of the first limiting block has an upper protrusion; a limiting pull block, including a central horizontal plate and two lower protrusions respectively disposed at both ends of the horizontal plate; the two ends of the limiting pull block respectively pull the upper protrusion and the inner side of the frame, thereby limiting the frame.

[0005] As a further improvement of this application, the bottom of the first limiting block is provided with a downward protrusion, the protrusion is inserted into the limiting groove, and the width of the protrusion is equal to the width of the limiting groove.

[0006] As a further improvement of this application, the rigid table surface is provided with three sets of holes, the distance between adjacent sets of holes is 275 mm, the distance between the edge of the hole set and the long side of the rigid table surface is 175 mm, and the distance between the two ends of the hole set and the short side of the rigid table surface is 205 mm; the hole set includes 12 screw holes, 6 screw holes are divided into a screw hole unit, two screw hole units are respectively set at the two ends of the rigid table surface 2, and the distance between the two screw hole units in the same hole set is 1210 mm; the screw hole unit is divided into three sub-screw hole units, each sub-screw hole unit includes two screw holes, the distance between the two screw holes in the sub-screw hole unit is 100 mm, the three sub-screw hole units of the screw hole unit are parallel to each other, and the distance between adjacent sub-screw hole units in the screw hole unit is 245 mm.

[0007] As a further improvement of this application, the workbench for door welding production also includes a second limiting block. The second limiting block includes a mounting plate disposed at the bottom, on which two rectangular holes are provided. The rectangular holes are fixed to the screw holes by bolts. An upper positioning block is disposed at the upper part of one end of the mounting plate, and a millimeter-thick relief groove is provided below it. The relief groove is used to accommodate the protrusion. The upper surface of the upper positioning block cooperates with the limiting pull block to limit the frame.

[0008] As a further improvement of this application, the limiting block is divided into different specifications according to its length, so as to adapt to the frame of different widths.

[0009] The beneficial effects of this utility model are as follows: by fixing the door frame at multiple points through the rigid tabletop, the first limiting block and the limiting pull block, the thermal deformation of the door frame is difficult to be transmitted to the welding positions at both ends of the door frame, so that the impact of the thermal deformation of the door frame on the welding position is minimized.

[0010] Furthermore, the quick-release structure of the limit block makes limiting and releasing the door frame during the production process very convenient and quick, which also increases the efficiency of door production. Attached Figure Description

A limiting protrusion 31 is provided, and there is a gap between the lower surface of the limiting protrusion 31 and the upper surface of the rigid table 2. The gap thickness is greater than the thickness of the protrusion. The limiting protrusion 31 is inserted into the space between the two protrusions on the edge of the frame. The top of the first limiting block 3 is provided with an upper protrusion 32. The limiting pull block 4 includes a middle horizontal plate 41 and two lower protrusions 42 respectively disposed at both ends of the horizontal plate 41.
