Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to the technical field of laser cutting. Background Art

[0002] Sheet metal parts are products processed by sheet metal technology, and they are indispensable in daily life. Sheet metal processing generally involves plastic deformation of some thin metal plates by hand or mold stamping to form the desired shape and size, and can be further formed into more complex parts through welding or a small amount of mechanical processing. For some sheet metal parts, a laser cutting device is required to cut the sheet into a specific shape before subsequent processing. Existing laser cutting devices generally place the sheet on a platform with multiple support columns. During the laser cutting process, due to the high temperature generated, thermal corrosion will occur on the top of these support columns. When the thermal corrosion is severe, the support columns need to be replaced or repaired. The timing of replacement or repair requires the operator to judge through experience, which is not intuitive enough, and replacement or repair is more troublesome. Summary of the invention

[0003] The purpose of the utility model is to solve the problems in the prior art and to provide a laser cutting device, which can provide an intuitive basis for judging whether a support block needs to be replaced and is relatively convenient for replacement.

[0004] To achieve the above-mentioned purpose, the utility model proposes a laser cutting device, including a machine platform, a guide rail, a walking gantry, a moving mechanism, a lifting device, a laser cutter, a fixed column, a spring, and a support block.

The walking gantry can actively move along the guide rails. A moving mechanism is installed on the crossbeam of the walking gantry, and the moving mechanism moves along the crossbeam of the walking gantry. The moving mechanism is connected to a lifting device, and the lifting device is connected to a laser cutter. A plurality of fixed columns are installed on the upper end surface of the machine platform, and the fixed column is vertically arranged. A vertically arranged mounting blind hole is provided on the fixed column, and the mounting blind hole is opened at the top end of the fixed column. The support block corresponds to the fixed column one by one, and a spring is fixed to the bottom end of the support block, and the spring is inserted into the mounting blind hole. The bottom end of the mounting blind hole is against the bottom end of the spring, and there is a gap between the bottom end of the support block and the top end of the fixed column.

[0005] Preferably, an external thread is provided on the outer surface of the fixing column, and a plurality of threaded holes corresponding to the fixing column and cooperating with the external thread are provided on the machine platform, and the fixing column is screwed on the threaded holes.

[0006] Preferably, the support block is in a spherical crown shape, and the bottom end of the support block is a plane.

[0007] Preferably, a protective tube is fixed on the bottom end surface of the support block, the protective tube surrounds the fixing column, and the bottom end of the protective tube is lower than the top end of the fixing column.

[0008] The beneficial effects of the utility model: the utility model fixes the spring at the bottom of the support block, and the spring is inserted into the installation blind hole, so that there is an intuitive basis for judging whether the support block needs to be replaced, and the replacement is more convenient.

[0009] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
