Referring to fig. 1 and 2, the present embodiment is for connecting a base plate 1 and an upper plate 2. The bottom plate 1 is fixedly connected with the bottom bending rib piece to form a stepped first connecting body; the upper plate 2 is fixedly connected with the upper bending rib to form a stepped second connector; the joint is inlayed with first connector to the second connector to through dismantling coupling assembling fixed connection, so that bottom plate 1 and upper plate 2 are located same horizontal plane.
Therefore, after the first connecting body and the second connecting body which are in the ladder shape are embedded and clamped, the bottom plate and the upper plate are connected in a detachable connecting assembly fixed connection mode. The connecting mode has good rigidity, is convenient to disassemble, and is very convenient to lift, install and transport.
In this embodiment, the bottom bending member is a bottom bending rib plate 3, and the upper bending member is an upper bending rib plate 4. And, first connector and second connector are the structure that has the cavity, removable coupling assembling is located the cavity. The advantage that first connector and second connector adopt the cavity structure is, can further improve sheet metal connection structure's rigidity. Because the solid structure has a lower stiffness than the hollow structure. In addition, the detachable connecting component is completely arranged in the cavity, the head and the root of the detachable connection cannot be exposed, and the appearance of the sheet metal connecting structure is more attractive.
Next, the structure of the first and second connectors will be described in detail.
The specific structure of the first connecting body is as follows: the bottom plate 1 is provided with a 90-degree flanging; the bottom bending rib plate 3 is provided with two 90-degree flanges and a 135-degree flange; the 90-degree flanging of the bottom plate 1 is fixedly connected with the 90-degree flanging of the bottom bending rib plate 3 at the free end; the 135-degree flanging of the bottom bending rib plate 3 is fixedly connected with the horizontal part of the bottom plate 1.
The specific structure of the second connector is as follows: the upper plate 2 is provided with two 90-degree flanges; the upper bending rib plate 4 is provided with a 90-degree flanging and a 135-degree flanging; the 90-degree flanging of the upper bending rib plate 4 is fixedly connected with the 90-degree flanging at the free end of the upper plate 2; the 135-degree flanging of the upper bending rib plate 4 is fixedly connected with the horizontal part of the upper plate 2.
By these two connection methods, a first connection body having a step shape and a second connection body having a step shape are formed. The purpose of adopting 90-degree flanging and 135-degree flanging is that the rigidity of the sheet metal part connecting structure can be further improved by the structural part at the angle. Moreover, the flanging not only can play the role of a connecting plate, but also can play the role of a reinforcing rib.

Tests prove that when the plate thickness is 1.5-5 mm, a copper ferrule is preferably used. Thicker plate, or cutting sleeve made of other materials. The present invention is not particularly limited herein.
The connection principle of the embodiment of the sheet metal part connection structure shown in fig. 2 is explained below with reference to fig. 3:
firstly, connecting a bottom plate 1 and a bending rib plate 3 together through spot welding, wherein the spot welding plays a good role in preventing water of a connecting structure of a sheet metal part;
then, the upper plate 2 and the sleeve 5 are connected together by fillet welding;
then, the upper plate 2 and the upper bending rib plate 4 are connected together through spot welding, and the spot welding plays a good role in preventing water of the connecting structure of the sheet metal part;
then, matching the welded bottom plate 1 with the welded upper plate 2;
then, a third plate hole A3 on the bottom bending rib plate 3 is drilled,
then, clamping the copper clamping sleeve 7 in a third plate hole A3 of the bottom bending rib plate 3 by the core pulling principle;
finally, the bottom plate 1 and the upper plate 2 are locked by screws 6.
When the screw 6 is disassembled, the screw can be directly unscrewed, and at the moment, the copper ferrule 7 on the screw 6 is still tightly clamped in the hole A3 of the bottom bending rib plate 3. Because copper cutting ferrule 7 can not drop when dismantling, consequently, the dismouting of bottom plate 1 and upper plate 2 can be more convenient.
From the above description of the embodiments it can be seen that:
the advantages of this embodiment are: the sheet metal part connecting structure has the advantages of high rigidity, good waterproof effect, convenience in disassembly and assembly, attractive appearance and high reliability; and because the adjusting allowance is arranged between the bottom plate and the upper plate, the two plates can be more conveniently ensured to be positioned on the same plane after being connected, and the connecting device is particularly suitable for connecting sheet metal parts with the plate thickness of 1.5-5 mm in the machine tool industry and other industries.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
