Problems solved by technology

[0005] The characteristic of large-scale EDM machine tools is that the longitudinal length of the machine tool is getting larger and larger, and the length of the liquid tank door is also getting longer and longer. In order to ensure sufficient rigidity, the weight of the working liquid tank door of large-scale machine tools is very large. The quadrilateral connecting rod and cylinder lifting mechanism cannot stably lift such a heavy tank door

Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the embodiment of the present invention is described further: see figure 1 , figure 2 , the working fluid tank 2 of the large electric discharge machine tool is set on the base of the machine tool, and the workbench of the machine tool is placed in the working fluid tank 2 . The volume of the working liquid tank 2 is very large, especially the die dimension is very large.

[0028] The working liquid tank 2 consists of a liquid tank body 5, two inner wall panels 6, two outer guard plates 8, two guide plates 7 fixedly installed on the inner sides of the two outer guard plates 8, It consists of a liquid tank door 11 hinged by an upper door 9 and a lower door 10 and a hydraulic drive mechanism 12 .

[0029] Because the longitudinal length of the liquid tank body 5 is too long, and the rear wall is undoubtedly the weakest link in the pressure bearing capacity of the working liquid tank 2, an auxiliary pressure-bearing mechan...

Abstract

The invention discloses a working fluid tank door for a large-sized electrical discharge machining tool; the working fluid tank door comprises a tank body, a tank door of the tank body includes an upper door and a lower door, the lower end of the upper door is connected to the upper end of the lower door, the lower end of the lower door is provided with a hinge hinged to a base of the tool, the left and right ends of the upper door are connected with hydraulic driving mechanisms respectively; the hydraulic driving mechanisms drive the tank door to open or close. The working fluid tank door has the advantages of compact structure, small operation spatial range, good opening-closing stability of the tank door, good convenience of opening and closing, good convenience of sealing, availability for self-locking, low energy consumption and the like.

Description

technical field [0001] The invention relates to an accessory device of a machine tool, more precisely a working fluid tank door suitable for a large electric discharge machine tool. Background technique [0002] At present, large-scale EDM machine tools on the market still adopt a double bullhead structure, that is, the EDM spindle is supported by a single column cantilever. With the continuous improvement of the level of electrical machining technology, the stroke of the EDM machine tool continues to increase, and the traditional double bullhead structure is difficult to meet the requirements of processing performance, so the gantry structure commonly used in large cutting machine tools is introduced into the EDM machine tool. [0003] Because the whole process of EDM is to remove the machining allowance of the workpiece bit by bit under the condition that the tool electrode and the working fluid are turned on and off repeatedly. This requires the workpiece to be immersed ...
