Problems solved by technology

Although the use of unscrambling is much less labor-intensive than manual stacking, there are still some problems in the actual implementation of this kind of jig and its unscrambling mode. The most important thing is that the silicon steel sheet is twisted and deformed on the column, and the internal stress is not easy to release. , so that the silicon steel sheets are not easy to be flattened, so the effect of the existing sheet unscrambling fixture is still not good, resulting in poor precision and low quality of the final welded product
[0006] 2) Due to the heavy weight of the stacked silicon steel shee...

Embodiment 1

[0052] Example 1: First combine Figure 1~Figure 7 A specific implementation of the silicon steel sheet high-precision automatic welding device of the present invention is described as follows:

[0053] The device has a workbench 1 provided with a feeding mechanism, a welding station A arranged on the workbench 1, and a welding mechanism and a sheet sorting mechanism arranged corresponding to the welding station A.

[0054] to combine figure 1 and figure 2 As shown, the feeding mechanism in this embodiment adopts a double-station feeding mechanism, which has two parallel guide rails 2 that are fixed on the workbench 1 and pass through the welding station A and slide on the parallel guide rails 2 Two sliding stages 3, each sliding stage 3 is provided with a silicon steel sheet stacking seat 21 for stacking silicon steel sheets x; the two sliding stages 3 are respectively connected to a translational drive mechanism, and are driven by The corresponding translational drive me...

Embodiment 2

[0076] Example 2: see Figure 8~Figure 9 As shown, the improvement of this embodiment compared with Embodiment 1 is that the sliding platform 3 adopts a floating sliding platform, and the floating sliding platform is a double-layer structure with an upper platform 13 and a lower platform 14. The upper platform 13 is wider than the lower platform 14 in the example. The upper platform 13 and the lower platform 14 are correspondingly provided with perforations for the push rod 10 to pass through; the bottom of the lower platform 14 is fixed with four sliders 15 to cooperate with the guide rail 2, and the top of the lower platform 14 is provided with an elastic buffer mechanism 16 The connection supports the upper platform 13 . In this embodiment, the elastic buffer mechanism 16 adopts pneumatic top cylinders, and the number is 6, which are divided into two rows along the guide rail 2 and symmetrically arranged on the lower platform 14 .

Abstract

The invention discloses a high-precision automatic welding device for silicon steel sheets. The high-precision automatic welding device for the silicon steel sheets comprises a worktable with a feeding mechanism, welding stations arranged on the worktable, a welding mechanism and a sheet arranging mechanism, wherein the welding mechanism and the sheet arranging mechanism are arranged in correspondence to the welding stations. The feeding mechanism achieves alternative feeding through a dual-station feeding mechanism, and work efficiency is greatly improved; according to the welding mechanism,a lifting mechanism is adopted to drive a lifting rotating type welding gun mechanism, and a welding gun can be driven to rotate so as to implement inclined welding action; and a poking type sheet arranging mechanism is adopted as the sheet arranging mechanism, an ejector rod is adopted in the mechanism for upward poking the silicon steel sheets in an interference manner for pressing, and the silicon steel sheets can be pressed more tightly. In total, defects of an existing device in the prior art are overcome, the sheet arranging effect, work efficiency and welding precision are greatly improved, and the device is a relatively precise device, has multiple functions, and is very high in automation degree, and capable of saving enterprise production cost. Meanwhile, the quality of silicon steel sheet welding motor products of an enterprise is improved.

Description

technical field [0001] The invention relates to an automatic welding device, in particular to a high-precision automatic welding device for silicon steel sheets. Background technique [0002] In order to reduce hysteresis loss and eddy current loss and prevent overheating during operation to reduce performance or even burn out, the stator core of the motor in the known technology is usually laminated with silicon steel sheets and then pressed or welded. Especially for a type of motor used in new energy vehicles and EMUs, the diameter is usually 120mm~1m, and the height is 45mm~1m. Obviously, the above-mentioned silicon steel laminated motor stator must be used to reduce magnetic loss. [0003] When the conventional technology produces the above-mentioned silicon steel sheet stator, the sheet is mainly sorted manually, and then transferred to the automatic welding equipment for welding operation, which has the following disadvantages: [0004] 1) Manual chipping is slow and ...
