Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting machine equipment, and specifically relates to a slag removal device for a laser cutting machine. Background Art

[0002] The laser cutting machine irradiates the surface of the workpiece with a laser beam, and the energy released causes the workpiece to melt and evaporate, thereby achieving the purpose of cutting and engraving. In this process, the melted material will form slag. The traditional way to clean the slag is to peel off the slag one by one through grinding or cutting tools.

[0003] Since the sword fence is flat, the melted slag often hangs on both sides of the sword fence. The slag on both sides needs to be ground by two grinding wheels respectively, and one motor with a coupling drives the two grinding wheels. While grinding, use the handle to push the motor and the two grinding wheels forward along both sides of the sword fence.

[0004] When removing slag from the sword grid of a laser cutting machine, the motor is pushed forward with a handle, and a support wheel is set under the motor to move along the sharp teeth of the sword grid. The support wheel and the two grinding wheels are only straightened by the handle. It is difficult for the two grinding wheels to have the same load when they contact the waste slag, causing the support wheel and the two grinding wheels to be skewed, and the edges of the two grinding wheels to scratch the sword grid. For this reason, we propose a slag removal device for a laser cutting machine. Utility Model Content

When cleaning the waste slag, the sword grid is vacated first, and the three-phase power is connected to the driving element Drive two grinding wheels to rotate, put the mounting seat on a row of sword grids, support the steel balls with support rods and hemispherical seats, use these steel balls to hold both sides of the sword grid, and arrange at least two steel balls on each side of the sword grid, so as to straighten the mounting seat and center it on the sword grid, and drive the two grinding wheels to be parallel to the sword grid, and use the two grinding wheels to continuously grind the waste residue attached to the sword grid, so as to reduce the occurrence of grinding the sword grid due to the skewness of the two grinding wheels, and then push the mounting seat forward along the axial direction of the sword grid, and the steel balls rotate inside the hemispherical seat to avoid sliding friction, so as to facilitate the smooth advancement of the entire device and grind the sword grid row by row.

[0008] The driving element includes two servo motors, the lower surfaces of the two servo motors are fixedly connected to the upper surface of the mounting seat, and an annular belt is arranged between the output ends of the two servo motors and the middle of adjacent grinding wheels. The two servo motors rotate the belts in opposite directions, driving the two grinding wheels to grind the waste slag in opposite directions, thereby forming a shearing effect at the grinding position of the sword grid and removing as much waste slag as possible.

[0009] A transmission shaft is axially fixed in the middle of the two grinding wheels, and the ends of the two transmission shafts that are away from each other extend out of the mounting seat. Two belts are respectively inserted into the two transmission shafts. The belts cooperate with the transmission shafts to drive the grinding wheels to rotate, and the transmission shafts can vertically support the grinding wheels to reduce the degree of vertical deviation when the grinding wheels are loaded.

[0010] Support bearings are installed on both sides of the mounting seat. The two support bearings are respectively sleeved on the outside of the two transmission shafts. Once the grinding wheel is slightly deflected, one side of the grinding wheel will contact the support bearings and be straightened by the support bearings to control the deflection of the grinding wheel. At the same time, the outer ring of the support bearing can rotate with the grinding wheel.

[0011] A walking wheel is rotatably installed in the middle of the upper wall of the mounting seat. The walking wheel is parallel to the two grinding wheels. The walking wheel can be placed on the upper surface of the sword fence to support the mounting seat. When the mounting seat is pushed, the walking wheel can be driven to roll on the upper surface of the sword fence to avoid sliding friction.

[0012] A push handle in a "V" structure is fixed on the upper edge of the mounting seat, and both ends of the push handle have rounded corners. The mounting seat can be pushed by holding the push handle with both hands, and pushing with both hands has higher stability.
