Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
The assembly and welding of the sheet metal parts are common in the current technological production, for example, the integral arrangement between a plurality of disks at the back cover of the clock requires the welding technology to be matched with the assembly technology for completion. For welding two disc-shaped material parts, the first guaranteed parameter is concentricity, and the second is the influence of factors such as deformation and mechanical interference of the material parts in the fixing process on the whole process.
The clamping process in the prior art usually fixes the edge of the material and then performs a welding operation. The fixing mode has the advantages that the stress surface is small, and errors in the clamping process can cause slight deformation, damage and the like of the surface of the material part. In addition, in the clamping process, two conveying mechanisms are usually adopted to convey two materials to specified positions respectively, and the position of each material is positioned through the positioning of a sensor or a mechanical direct collision limiting mode. And the mode of centering can not be adopted any more in the process of butt joint of the two material parts, so that the concentricity of the two material parts can be poor due to the influence of errors such as detection errors of a sensor, looseness and deformation after long-term collision of machinery and the like. In addition, the two material pieces are usually butted by the two clamping mechanisms in the butting process, so that the subsequent welding work is greatly influenced; if the clamping assembly is directly removed after the two material parts are stacked together, the position of the first material part and the second material part can be loosened due to no external force applied between the first material part and the second material part.

Through foretell setting mode, can make above-mentioned material area that has a plurality of first material 1 can convey forward smoothly accurately in foretell guide way under the effect of external force better. Wherein preferably, the first material part 1 and the second material part 2 are both positioned in a horizontal plane during the conveying and the abutting process; the supporting platform 31 has a preset processing position, the supporting platform 31 is provided with a docking space running through the upper and lower surfaces of the supporting platform at the preset processing position, and the first material 1 is suspended when being conveyed into the docking space.
As shown in fig. 2 and fig. 3, the first pressing assembly 4 includes a first driving member (not shown), a first pressing body 41, and an elastic member 45 disposed between the first driving member and the first pressing body 41. Wherein the first drive member comprises a servo motor or a drive cylinder and further comprises a second sheet element 44 at the output end of the first drive member. Wherein the second sheet member 44 is capable of reciprocating in the up-down direction by the servo motor or the driving cylinder. It should be noted that the first driving member, the second plate 44, the elastic member 45 and the first pressing assembly 41 are sequentially disposed from top to bottom, and the second plate 44 and the first pressing assembly 41 are located in a horizontal plane.
In the above manner, the first pressing body 41 is provided with a plurality of welding through holes 43 extending downward from the upper surface and penetrating through the lower surface, and the size and number of the welding through holes 43 can be adaptively set according to requirements.

Specifically, the first plate member 51 and the second press body 52 are provided with a plurality of corresponding connecting holes 53, and the connecting holes 53 extend in the up-down direction. In one embodiment, the diameter of the connecting hole 53 of the second press body 52 is larger than the diameter of the connecting hole 53 of the first sheet material 51, so that the T-shaped connecting member 54 can be directly inserted into the two connecting holes 53. The connector 54 can abut on the upper surface of the first plate member 51, and the connector 54 is in clearance fit with the connection hole 53.

Preferably, the fit clearance between the first positioning hole and the first positioning piece 55 is smaller than the allowable relative error value of the first material part 1 and the second material part 2 in the horizontal plane. Thus, the first positioning piece 55 is inserted into the first positioning hole, and the relative position of the second pressing body 52 relative to the first plate 51 is adjusted in a horizontal plane by means of mechanical limiting, so that the centering process between the first material 1 and the second material 2 is effectively completed.
