Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting equipment, in particular to an interactive double-platform laser cutting machine. Background Art

[0002] In sheet metal processing, laser cutting equipment mostly uses a single platform or a chain-driven exchange workbench. The single platform is limited by the working gap and cannot perform other material preparation and loading operations, which greatly limits production efficiency, wastes a lot of manpower and material resources and causes unnecessary losses. Although the traditional chain-driven exchange work platform solves the problem of difficulty in loading and preparing materials while working, it realizes that loading and cutting do not interfere with each other, and can also save time and avoid labor waste. However, the chain drive has low positioning accuracy and large reverse clearance, resulting in zero point misalignment and excessive positioning deviation after the upper and lower workbenches are exchanged.

[0003] In addition, most laser cutting equipment has the following problems when in use. The laser cutting machine needs to consider the problem of waste discharge. At the same time, in order to improve the clamping accuracy of the material, the loading table of the laser cutting platform is mostly set in a leaky mesh shape. The contact between the platform and the material is point contact or line contact. When cutting and loading for precise positioning, the equipment needs to automatically push the material to complete the positioning. At this time, the contact point between the material and the cutting platform produces relative sliding, which can easily cause friction damage. When processing some soft metals, the surface of the metal sheet is severely scratched. Utility Model Content

The upper half of the pulley of the synchronous belt is fixed to the second cutting platform 5 of the second layer, and the lower half of the pulley of the synchronous belt is fixed to the first cutting platform 4 of the first layer. When the first cutting platform 4 moves to the processing station, the second cutting platform 5 is brought back to the loading station.

When the first cutting platform 4 moves to the processing station, the second cutting platform 5 is brought back to the loading station, and vice versa. The first cutting platform 4 and the second cutting platform 5 move interactively in this way. Compared with the chain-driven interactive moving platform, it has higher precision and smaller repeated positioning error, and can be suitable for batch production and processing.

[0043] When the first cutting platform 4 moves to the loading position, the lifting platform 31 rises to a height where the universal ball 34 is higher than the upper end surface of the partition provided on the first cutting platform 4. When the second cutting platform 5 moves to the loading position, the lifting platform 31 rises to a height where the universal ball 34 is higher than the upper end surface of the partition provided on the second cutting platform 5. When loading, the operator or the loading robot places the material on the loading platform. At this time, under the support of the universal ball 34, the plate only contacts the universal ball 34, so that when the plate moves close to the positioning ruler 41 and the positioning block 42, it can avoid scratching and damage to the partition.
