Description

Technical Field

[0001] The utility model relates to the technical field of gantry machine tools, in particular to a bed structure of a moving column type gantry machine tool. Background Art

[0002] The moving column gantry machining center has a column that drives the crossbeam to move forward and backward, and the spindle box on the crossbeam moves up and down and left and right to complete the cutting. The guide rails of the moving column gantry machining center are on the ground, and hard rails are usually used. Guide rail covers are provided on the guide rails, so it is inconvenient to operate. In addition, since the movement of the column requires a high-power motor to drive it, the energy consumption is relatively large. The advantage is that it is suitable for heavy cutting of large parts, so it is widely used.

[0003] During the use of the gantry machine tool, the position of the processing device needs to be moved and adjusted in the front and back, left and right, and up and down directions. The machine tool is set on a track, and the track drives the machine tool to move. At the same time, when the processing device processes the workpiece, the processing device moves downward to contact the workpiece, and the processing device applies downward pressure to the workpiece, and then processes the workpiece. When the processing device applies pressure to the workpiece, the machine tool as a whole will generate an upward reverse force. Under the state of reverse force, it is easy to cause the bed to deviate from the track, and then cause the lathe to shake and change the angle, affecting the turning efficiency. For this reason, we proposed a bed structure of a moving column gantry machine tool. Utility Model Content

The lower part of the base 5 is fixedly connected to a pulley seat 6, and the front end of the base 5 is fixedly connected to a mounting plate 7. The front end of the mounting plate 7 is installed with a limiting buckle 8 through a limiting pin 9.

When the second movable sleeve 16 moves downward, the material can be cut, and the motor 19 is started, and the motor 19 and the second gear 18 perform a threaded motion. At the same time, the processing device positioning sleeve 17 adjusts the angle of the shoelace processing tool 21. By adjusting the angle of the processing tool 21, the processing tool 21 can adjust the cutting direction, and when processing the material, the limiting buckle 8 is sleeved inside the first limiting slide groove 2 to avoid reverse pressure when the base 5 is cut, which then causes the base 5 to tilt.
