Description

Technical Field

[0001] This utility model relates to the field of grooving machine technology, specifically to a double-screw lateral movement automatic compensation grooving machine. Background Technology

[0002] The automatic lateral movement compensation of the twin-screw grooving machine is a key technology that marks the equipment's entry into the ranks of high-end, precision, and intelligent systems. It's not merely a matter of hardware accumulation, but a deep integration of precision mechanical engineering and intelligent control algorithms. Ultimately, the core value it brings to users is: extremely high processing quality, ultra-long precision lifespan, maximized production efficiency, and the lowest scrap rate.

[0003] However, in implementing the relevant technologies, the following problems were found in the existing technologies: Traditional single screw driven transverse mechanisms, especially in the case of large span, heavy load, and high-power spindle, have several inherent defects, such as insufficient rigidity. During cutting, the crossbeam driven on one side is prone to twisting and vibration, which affects the machining accuracy and surface finish. If a single motor + long transmission shaft is used to drive both sides, the transmission chain is long and there may be slight synchronization errors. Traditional single-screw driven transverse mechanisms cannot perform maintenance such as cleaning, drying, and lubrication of the screw after use, resulting in contaminants affecting the screw transmission efficiency and reducing its service life. Therefore, a dual-screw transverse automatic compensation grooving machine is proposed. Utility Model Content

[0013] The working principle and beneficial effects of this utility model are as follows: 1. By starting the dual servo motors, the dual servo motors drive the dual lead screws to rotate inside the mounting housing. The linkage slider moves through the threads on the dual lead screws, and the moving block slides inside the slide groove. This is used to move the grooving machine to perform grooving work. The dual lead screws jointly bear the cutting reaction force, which greatly improves the rigidity of the beam system, reduces vibration and deformation, avoids the "torsion" or "asynchrony" phenomenon that may occur with single lead screw drive, and ensures the positioning accuracy of the processing head at any position on the Y axis.

[0014] 2. By starting the water pump and water valve, which controls the opening and closing of the water inlet pipe, the water pump draws water from the tank to clean the double lead screw. By starting the air pump and air valve, which controls the opening and closing of the air supply pipe, the air pump draws air from the filter box. During this process, external air enters the filter box and is filtered through the filter cotton and air filter. The filtered air is then heated by the heating wire to dry the double lead screw. By starting the oil pump and oil valve, which controls the opening and closing of the oil supply pipe, the oil pump draws lubricating oil from the oil tank to add lubricating oil to the double lead screw. The sealed pipe delivers the incoming air, water, and lubricating oil to the hose, which then delivers them to the distributor pipe. The distributor pipe disperses the air, water, and lubricating oil into four circular nozzles for cleaning, drying, and lubricating the double lead screw, thereby improving its service life.
