Description

Technical Field

[0001] This utility model relates to an oil tank structure, and more particularly to a layered lifting oil tank structure for an electrical discharge machining (EDM) machine, belonging to the technical field of EDM machines. Background Technology

[0002] An electrical discharge machining (EDM) machine is a machine that uses electrical discharge machining technology to manufacture and process metal workpieces. EDM machining involves immersion and flushing with EDM oil as the working fluid; therefore, the machine tool is equipped with an oil tank to hold the oil. For easy loading and unloading of workpieces, the oil tank is designed with a lifting door; when lowered, the door is below the worktable surface. To facilitate integration into automated production lines, a three-sided opening automatic lifting oil tank, controllable by the machine tool's CNC, is designed, allowing for easy loading and unloading of workpieces by robotic arms in automated production lines.

[0003] Because there is oil on the inner wall of the automatic lifting door, and oil seepage also occurs at the door's seal, a drip tray is installed at the bottom of the automatic lifting door to catch the dripping oil and allow it to flow back to the oil tank by gravity, which requires reducing the door's height. However, existing automatic lifting doors cannot fully meet these requirements. Therefore, a layered lifting oil tank structure for an EDM (Electrical Discharge Machining) machine is proposed. Utility Model Content

[0004] In view of this, the present invention provides a layered lifting oil tank structure for an EDM machine to solve or alleviate one of the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: A layered lifting oil tank structure for an EDM machine includes a machine tool worktable. An upper lifting door guide groove and a middle lifting door guide groove are symmetrically arranged on both sides of the machine tool worktable. An upper lifting door is slidably connected inside the upper lifting door guide groove. A middle lifting door is slidably connected inside the middle lifting door guide groove. Upper transmission block grooves are arranged on both sides of the upper lifting door, and upper transmission blocks are slidably connected inside the upper transmission block grooves. A fixed oil tank is installed at the bottom of the machine tool worktable. Middle transmission block grooves are arranged on both sides of the middle lifting door, and middle transmission blocks are slidably connected inside the middle transmission block grooves. An oil tank transmission slider groove is arranged inside the fixed oil tank, and a fixed transmission slider groove is slidably connected inside the oil tank transmission slider groove. A fixed oil tank drive slider is used. A drive chain is fixedly connected to the rear surface of the two upper lifting doors. The drive chain contains drive sprockets, transition sprockets A, B, and C. The drive sprockets are fixedly connected to the outside of the drive shaft via two drive keys. The drive shaft is fixedly connected to the output shaft of a right-angle reduction motor via a coupling. The right-angle reduction motor drives the drive shaft and the two drive sprockets to rotate, which in turn drives the drive chain to pull the two upper lifting doors along the lifting door positioning guide rail. During the movement of the upper lifting doors, the upper drive block and the upper drive block slide groove cooperate to drive the linkage lifting mechanism to extend or compress, causing the middle drive block and the fixed oil tank drive slider on the linkage lifting mechanism to move. This causes the middle lifting door to move simultaneously with the upper lifting doors, and both sides move synchronously, improving the stability of the automatic lifting door during lifting.

[0006] A further preferred embodiment: symmetrical lifting door positioning guide rails are installed on both sides of the machine tool worktable, and an upper lifting door guide bracket and a middle lifting door guide bracket are slidably connected to one side of the lifting door positioning guide rails.

[0007] A further preferred embodiment: the upper-level lifting door guide bracket and the middle-level lifting door guide bracket are fixedly connected to the upper-level lifting door and the middle-level lifting door, respectively.

[0008] A further preferred embodiment is provided with a sealing strip A between the upper lifting door and the middle lifting door, and a sealing strip B between the fixed oil tank and the middle lifting door.

[0009] A further preferred embodiment: a liquid receiving tray is fixedly connected to the lower part of the fixed oil tank.

[0010] A further preferred embodiment: the liquid receiving tray is internally fixedly connected to a lifting mechanism support.

[0011] A further preferred embodiment: a linkage lifting mechanism is installed on the inner side wall of the lifting mechanism support.

[0012] A further preferred embodiment: the upper transmission block, the middle transmission block, and the fixed oil groove transmission slider are connected to the linkage lifting mechanism.

[0013] The present invention has the following advantages due to the adoption of the above technical solution:

[0014] This invention uses a right-angle geared motor to drive two transmission sprockets to rotate, which in turn drives the transmission chain to move two upper-level lifting doors. During the movement of the upper-level lifting doors, the linkage lifting mechanism is extended or compressed, causing the upper-level transmission block, middle-level transmission block, and fixed oil groove transmission slider on the linkage lifting mechanism to move. This causes the middle-level lifting door to move simultaneously with the upper-level lifting doors, and the two sides move synchronously, thus improving the stability of the automatic lifting doors during lifting.
