Breakage-preventing floating track feeding device for silicon steel sheet welding

Abstract

The invention discloses a breakage-preventing floating track feeding device for silicon steel sheet welding. The breakage-preventing floating track feeding device comprises a workbench provided with a pressurization station, parallel guide rails arranged on the workbench and passing through the pressurization station and a slide carrying table arranged on the parallel guide rails and used for placing a silicon steel sheet positioning jig, wherein a pressurizing device for pressurizing a silicon steel sheet is arranged above the pressurization station. The breakage-preventing floating track feeding device is characterized in that the slide carrying table is a floating slide carrying table, is of a double-layer structure and comprises an upper-layer platform and a lower-layer platform, slide blocks are fixed to the bottom of the lower-layer platform and matched with the guide rails, and an elastic buffering mechanism is arranged at the top of the lower-layer platform and is connected with and supports the upper-layer platform. In addition, a rigid supporting block located below the upper-layer platform is fixed to the pressurization station, a buffering interval is reserved between the bottom of the upper-layer platform and the top of the rigid supporting block. The device can greatly reduce the impact force of the pressurizing device to the guide rails and effectively prevent the guide rails from breaking, the overall service life of the device is greatly prolonged, the device maintenance costs of enterprises are reduced, and the silicon steel sheet welding quality is ensured.

Description

technical field [0001] The invention relates to an automatic rail feeding device, in particular to a fracture-proof floating rail feeding device for silicon steel sheet welding. 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, it is first necessary to sort the silicon steel sheets, that is, the silicon steel sheets are stacked and stacked by manual or robotic equipment, and positioned by a simple sheet s...

AI Technical Summary

Problems solved by technology

[0006] Since the silicon steel sheet is directly placed on the sliding platform for pressurization, when the pressurization equipment pressurizes the silicon steel sheet, it will inevitably cause impact on the guide rail

If the pressure of the pressurized equipment is not properly controlled, it will cause the guide rail to break in severe cases, increasing the maintenance and replacement costs of the enterprise

Even if it does not cause serious damage, over time, it will greatly reduce the bearing capacity of the guide rail in the section of the press station, causing it to bend and deform, reducing the matching accuracy between the guide rail and the slider at the bottom of the sliding platform, and making the movement of the sliding platform The stability is greatly reduced, the overall life of the device is reduced, and at the same time it affects the quality of subsequent welding products, which is likely to cause product scrapping
