The working oil tank of the EDM machine tool in the prior art is usually integrated with the workbench, and the workbench and the oil tank arranged around it form a working chamber. An oil discharge pipeline is arranged under the working chamber. The valve on the oil pipeline realizes the collection and discharge of the working fluid; and an open-door structure is set on one side of the working chamber for installing and dismounting the workpiece. This structure makes the discharge of the working fluid and the work efficiency of the disassembly and assembly of the workpiece are lower

Embodiment
[0024] Example: such as Figure 1 to Figure 5 As shown, an automatic lifting oil tank device of an electric discharge forming machine includes a working oil tank 1 fixed to the workbench, a working chamber is formed between the workbench and the working oil tank 1, and an oil inlet communicating with the working chamber is provided on the working oil tank. The pipeline 2 and the oil outlet pipeline 3, the oil inlet pipeline 2 and the oil outlet pipeline 3 are respectively provided with valves to control their opening or closing. The oil tank 1-1 is a middle oil tank 1-2 that can be sealed and raised, and an upper oil tank 1-3 that can be sealed and raised relative to the middle oil tank 1-2. The oil inlet pipeline 2 and the oil outlet pipeline 3 are arranged on the lower oil tank 1-1. The lower oil tank 1-1 includes a base part 1-1-1 and an upright part 1-1-2 extending upward from the rear side of the base part 1-1-1. The two sides of the upright part 1-1-2 are respectively pr...

The invention discloses an automatic lifting oil tank device of an electric spark forming machine. The automatic lifting oil tank device comprises a working oil tank. The working oil tank comprises a lower oil tank body fixedly connected with a worktable, an intermediate oil tank body capable of conducting sealing lifting relative to the lower oil tank body and an upper oil tank body capable of conducting sealing lifting relative to the intermediate oil tank body. The lower oil tank body comprises a base part and a vertically-arranged part extending upward from the rear side of the base part. A first guiding groove and a second guiding groove are longitudinally formed in the two sides of the vertically-arranged part correspondingly. The intermediate oil tank body and the upper oil tank body are of a U-shaped coaming structure. The two side edges of the intermediate oil tank body and the upper oil tank body are slidably connected with the first guiding groove and the second guiding groove in a sealing mode correspondingly. The automatic lifting oil tank device further comprises linear motors arranged outside the two sides of the lower oil tank body and used for driving the upper oil tank body to go up and down. Each linear motor comprises a linear motor magnet arranged outside the lower oil tank body and extending longitudinally and a linear motor coil arranged outside the upper oil tank body and arranged on the corresponding linear motor magnet in a sleeving mode. The automation degree is improved, the convenience of operation is improved, and leaking of oil liquid is avoided.
Description
technical field [0001] The invention relates to an automatic lifting oil tank device for an electric spark forming machine. Background technique [0002] EDM uses the working fluid as the discharge medium. The working fluid forms a spark to break down the discharge channel, and quickly restores the insulation state of the gap after the discharge; it compresses the discharge channel; it helps the electro-corrosion product to be thrown out and removed. In order to ensure the normal processing, it is necessary to use a special working oil tank to hold the working fluid. The working oil tank of the EDM machine tool in the prior art is usually integrated with the workbench, and the workbench and the oil tank arranged around it form a working chamber. An oil discharge pipeline is arranged under the working chamber. The valve on the oil pipeline realizes the collection and discharge of the working fluid; and an open-door structure is set on one side of the working chamber for inst...
