[0041] In the related art, the oil tank of the lifting oil tank is independently provided, and the oil tank and the bed are sealed by a sealing strip. In actual use, aging and failure of the sealing strip are inevitable, and after long-term use, the EDM fluid will leak onto the ground.

[0042] According to the embodiment of the utility model, the lifting oil tank EDM machine tool is provided. Figure 1 , including a bed 1 and a lifting oil tank device.

[0043] The bed 1 is provided with an oil tank, and the oil tank is provided with a top opening. The lifting oil tank device is connected to the bed 1 and is provided corresponding to the top opening of the oil tank. The bed 1 is the main supporting frame or base part of the processing machine tool, and is the main part of the entire processing machine tool, which is used to carry and fix other components. The shape of the bed 1 can be set as needed, for example, it can be set to a rectangular structure for easy transportation and installation. An oil tank is constructed inside or at other parts of the bed 1, and the oil tank is a container for storing electrospark machining fluid. Generally, the machining fluid in the oil tank can be passed into the oil tank through a pump group, and the machining fluid can be recycled during the working process and can be discharged into the oil tank again. The oil tank is provided with an opening at its top, and the top opening is connected to other components, such as a lifting oil tank device.

[0044] The lifting oil tank device is installed on the bed 1, wherein the lifting oil tank device at least includes a lifting oil tank 8 and a lifting assembly, and the height of the lifting oil tank 8 can be adjusted to meet the needs of immersing the workpiece in the processing fluid during processing or exposing the workpiece after processing. The position of the lifting oil tank device corresponds to the top opening of the oil tank, so that the lifting oil tank device can be connected to the inside of the oil tank through the top opening of the oil tank, and the liquid in the oil tank can be pumped into the oil tank when needed, or the liquid in the oil tank can be returned to the oil tank, which helps to realize the automatic supply or discharge of liquid and improve the operating efficiency and convenience of the equipment.

[0045] At the same time, when the machining fluid in the lifting oil tank device leaks, the machining fluid directly falls into the oil tank, the machining fluid can be reused, and will not leak on the ground.

[0046] In some embodiments, the bed 1 includes a bottom plate and side plates, and the side plates and the bottom plate are surrounded to form an oil tank.

[0047] See also Figure 1 and Figure 4 The bed 1 is mainly composed of a bottom plate and a side plate. The bottom plate is usually the basic part of the processing machine tool, supporting the weight and workload of the entire processing machine tool, while the side plate is used to provide additional stability and strength, as well as to form a specific spatial structure. The oil tank is not an independent component installed on the bed 1, but a liquid storage space enclosed by the side plate and the bottom plate. At this time, the oil tank is part of the structure of the bed 1, and its boundaries are defined by the side plate and the bottom plate. The oil tank and the bed 1 are designed and manufactured as a whole during the manufacturing process, which can reduce the assembly steps, improve the structural stability, reduce potential leakage points, and improve the sealing of the oil tank. The integrated structure makes the structure of the entire bed 1 simpler, reduces unnecessary parts and connectors, which may reduce manufacturing costs and improve the reliability of the equipment. At the same time, the integrated structure is also more practical, simplifies the maintenance and operation process, and can take into account both structural efficiency and functional practicality.

[0048] In some embodiments, the lifting oil tank EDM machine tool also includes a multi-axis motion mechanism, which includes at least a base 2 and a longitudinal slide 3. A longitudinal slide rail is provided on the top of the base 2, and the longitudinal slide 3 is slidably connected to the longitudinal slide rail; wherein, the longitudinal slide 3 is a box structure, and the width of the bottom surface of the box structure along the longitudinal direction is greater than or equal to a preset width.

[0049] See also Figure 1 In addition to the basic functions of electrospark machining and lifting oil tank 8, the processing machine tool is also equipped with a mechanism that can realize multiple axial movements (such as X, Y, Z axis, etc.), so that the machine tool can perform precise operations and processing in multiple dimensions. Among them, the X-axis is horizontal, the Y-axis is longitudinal, and the Z-axis is vertical. The base 2 refers to the supporting and fixing part of the entire multi-axis motion mechanism, and the longitudinal slide 3 is a component that can slide on the base 2, mainly used to realize movement in the longitudinal direction (for example, the Y-axis direction). A longitudinal slide rail is provided on the top of the base 2, and the longitudinal slide 3 is slidably connected to the longitudinal slide rail, and can move smoothly and accurately in the longitudinal direction.

[0050] In the related art, the longitudinal slide 3 is a bullhead slide type structure, in which the transverse slide 4 and the vertical slide 6 are arranged on a side surface of the longitudinal slide 3, which will cause the longitudinal slide 3 to have pitch deformation during movement, thereby reducing the processing accuracy.

[0051] In the embodiment of the utility model, the longitudinal slide 3 is constructed as a box structure, and the width of its bottom surface along the longitudinal direction is greater than or equal to the preset width, which can ensure the stability and load-bearing capacity of the longitudinal slide 3. The longitudinal slide 3 will not experience pitch deformation during movement, ensuring that the requirements of accuracy and efficiency can be met during electrospark machining.

[0052] In some embodiments, the multi-axis motion mechanism also includes a transverse slide 4 and a vertical slide 6. A transverse slide rail is provided on the side of the longitudinal slide 3, and the transverse slide 4 is slidably connected to the transverse slide rail. A vertical base 5 is provided on the side of the transverse slide 4 away from the longitudinal slide 3, and the vertical base 5 is provided with a vertical slide rail, and the vertical slide 6 is slidably connected to the vertical slide rail.

[0053] See also Figure 1 On the basis of the original longitudinal slide 3, the multi-axis motion mechanism also adds two additional slides (a transverse slide 4 and a vertical slide 6), which are used to realize transverse (for example, X-axis direction) and vertical (for example, Z-axis direction) movement respectively. At this time, the processing machine tool can realize precise positioning and processing in three-dimensional space. A transverse slide rail is provided on one side of the longitudinal slide 3, and the transverse slide 4 is installed on the slide rail by means of a sliding connection, so that the transverse slide 4 can slide on the transverse slide rail to realize movement along the X-axis direction. A vertical base 5 is provided on the side of the transverse slide 4 away from the longitudinal slide 3, and a vertical slide rail is provided on the vertical base 5. The vertical slide 6 is installed on the vertical slide rail by means of a sliding connection, so that the vertical slide 6 can slide on the vertical slide rail to realize movement along the Z-axis direction.

[0054] The multi-axis motion mechanism realizes flexible movement and precise positioning in three-dimensional space through the combination of the longitudinal slide 3, the transverse slide 4 and the vertical slide 6, and the corresponding slide rail design, thereby improving the operating range and processing accuracy of the EDM machine tool.

[0055] In some embodiments, the lifting oil tank device includes a fixed oil tank 7, a lifting oil tank 8 and a lifting assembly. The fixed oil tank 7 is connected to the bed 1. The lifting oil tank 8 is provided with a lateral opening on the side facing the fixed oil tank 7. The lifting oil tank 8 is slidably connected to the fixed oil tank 7, and the fixed oil tank 7 blocks the lateral opening; the lifting assembly is connected to the lifting oil tank 8 and the bed 1, and the lifting assembly is used to adjust the height of the lifting oil tank 8.

[0056] See also Figure 1 and Figure 2The lifting oil tank device is mainly composed of three parts: a fixed oil tank 7, a lifting oil tank 8 and a lifting assembly. The fixed oil tank 7 and the lifting oil tank 8 are used to store the electrospark machining fluid, and the lifting assembly is used to adjust the height of the lifting oil tank 8. The fixed oil tank 7 is installed on the bed 1 or the base 2, which can be directly welded, bolted or other fixed methods, providing a stable foundation for the entire lifting oil tank device. The lifting oil tank 8 is provided with a lateral opening on the side facing the fixed oil tank 7, and the lateral opening is to allow the lifting oil tank 8 to exchange or communicate with the fixed oil tank 7. For example, a liquid outlet is provided at a certain height position of the fixed oil tank 7. When the lifting oil tank 8 is lowered to this height, the machining fluid can be added to the lifting oil tank 8. Then, the height of the lifting oil tank 8 is raised. At this time, the machining fluid is stored in the area enclosed by the lifting oil tank 8 and the fixed oil tank 7 for the machining of the workpiece.

[0057] The lifting oil tank 8 is mounted on the fixed oil tank 7 by a sliding connection, and can move up and down along the fixed oil tank 7. At the same time, the fixed oil tank 7 will cover the lateral opening of the lifting oil tank 8 to prevent the EDM fluid from overflowing from the lateral opening.

[0058] One end of the lifting assembly is connected to the lifting oil tank 8, and the other end is connected to the bed 1. The height of the lifting oil tank 8 is adjusted by driving the lifting oil tank 8 to slide along the fixed oil tank 7. The operator can accurately control the liquid level of the EDM fluid in the lifting oil tank 8 according to the processing requirements, thereby optimizing the processing process and improving efficiency.

[0059] In some embodiments, the lifting oil tank device further includes a balancing support component 9, and the balancing support component 9 is located on a side of the lifting oil tank 8 facing away from the lifting assembly.

[0060] See also Figure 1 and Figure 2 In addition to the fixed oil tank 7, the lifting oil tank 8 and the lifting assembly, the lifting oil tank device is also equipped with a balancing support component 9 for providing stability and balance. The balancing support component 9 is arranged on the side of the lifting oil tank 8 away from the lifting assembly, which can effectively balance the moment generated during the lifting process and ensure the stable operation of the lifting oil tank 8.

[0061] In some cases, the balancing support component 9 can be a balancing cylinder, which is a component that uses gas pressure to perform telescopic movement and can provide stable support force and buffering effect. One end of the balancing cylinder is fixedly connected to the bed 1 to provide a stable foundation for the movement of the cylinder, and the other end is connected to the lifting oil tank 8 to provide corresponding support force and balancing effect when the lifting oil tank 8 is raised and lowered. In this way, the balancing cylinder can dynamically adjust its output force during the lifting process of the lifting oil tank 8 to ensure that the lifting oil tank 8 moves smoothly and accurately, thereby improving the overall performance and machining accuracy of the EDM machine tool. It should be noted that the number of balancing support components 9 can be multiple, and multiple balancing support components 9 are evenly arranged to improve the stability of the lifting oil tank 8.

[0062] In some embodiments, the lifting assembly includes a drive motor 10, a gear set and a rack. The drive motor 10 is connected to the bed 1, the gear set is transmission-connected to the drive shaft of the drive motor 10, the rack is connected to the side of the lifting oil tank 8 facing the gear set, and the rack is meshed with the gear set.

[0063] See also Figure 2 and Figure 3 The lifting assembly is mainly composed of a driving motor 10, a gear set and a rack. The driving motor 10 provides power, the gear set is responsible for transmitting power, and the rack cooperates with the gear set to realize the lifting and lowering movement of the lifting oil tank 8. The driving motor 10 is installed at a certain position of the bed 1, usually connected to the bed 1 through a fixed bracket or directly, to provide a power source for the entire lifting assembly. The gear set is connected to the driving shaft of the driving motor 10 through a transmission mechanism (such as a belt, chain or direct connection). When the driving motor 10 is running, it will drive the gear set to rotate through the driving shaft. The rack is installed on the side of the lifting oil tank 8 facing the gear set. When the gear set rotates, it can drive the lifting oil tank 8 to perform lifting and lowering movements by meshing with the rack. The teeth on the rack mesh with the gears in the gear set to form a mechanical connection that can transmit power and motion. When the driving motor 10 rotates through the gear set, it will drive the meshing rack to move up and down, thereby realizing the lifting and lowering movement of the lifting oil tank 8.

[0064] The lifting assembly converts electrical energy into mechanical energy through the coordinated work of the driving motor 10, the gear set and the rack, and accurately controls the lifting movement of the lifting oil tank 8, providing the necessary height adjustment function for the EDM machine tool.

[0065] In some embodiments, the lifting assembly further includes a connecting member and a linear guide rail, the connecting member is connected to the lifting oil tank 8, and the connecting member is configured with a lifting slide, the linear guide rail is vertically arranged, and the lifting slide is slidably connected to the linear guide rail.

[0066] See also Figure 2 and Figure 3In addition to the drive motor 10, the gear set and the rack, the lifting assembly also includes a connector and a linear guide. The connector is mainly used to connect the lifting oil tank 8 with the rack, etc., while the linear guide provides guidance and support for the lifting slide. The connector is installed on the lifting oil tank 8, and its function is to connect the lifting oil tank 8 with the lifting slide and other related components to form a complete lifting system. The lifting slide can slide along the linear guide, which carries the lifting oil tank 8 and moves up and down under the guidance of the linear guide. The linear guide is installed vertically, which can provide vertical guidance and support for the lifting slide, ensuring that the lifting oil tank 8 remains stable and precise during the lifting process. The lifting slide is installed on the linear guide by a sliding connection, and can slide up and down in the track of the linear guide, so that the lifting slide can be smoothly lifted and lowered along the linear guide with the cooperation of the drive motor 10, the gear set and the rack, thereby realizing the height adjustment of the lifting oil tank 8.

[0067] As part of the lifting assembly, the connecting parts and linear guides cooperate with the lifting slide to provide stable guidance and support for the lifting oil tank 8, ensuring the accuracy and stability of the lifting process, thereby improving the overall performance of the EDM machine tool.

[0068] In some embodiments, the lifting assembly further includes a guide rail fixing member, which is connected to the bed 1 and the linear guide rail.

[0069] See also Figure 2 and Figure 3 The lifting assembly also includes a guide rail fixing part specifically used to fix the linear guide rail. On the one hand, the guide rail fixing part is connected to the bed 1 and provides support and stability by being fixed at a specific position on the bed 1; on the other hand, the guide rail fixing part is also connected to the linear guide rail, and its function is to firmly install the linear guide rail on the bed 1 and ensure that the linear guide rail maintains an accurate position and direction during use.

[0070] The guide rail fixings may include bolts, brackets or other fastening elements, which can tightly fix the linear guide rails at the preset position of the bed 1 to prevent the linear guide rails from moving, shaking or deforming during the lifting process, thereby ensuring that the lifting slide can slide smoothly and accurately along the linear guide rails to achieve the height adjustment of the lifting oil tank 8. As an important part of the lifting assembly, the guide rail fixings provide reliable guidance and support for the lifting slide by firmly connecting the bed 1 and the linear guide rails, thereby ensuring the stability and accuracy of the lifting oil tank device.

[0071] In some embodiments, an overflow hole is provided on the top of the side wall of the lifting oil tank 8 .

[0072] See also Figure 2One or more overflow holes are designed at the top of the side wall of the lifting oil tank 8. The main function of the overflow hole is to control the liquid level of the EDM fluid inside the lifting oil tank 8. When the liquid level of the machining fluid in the lifting oil tank 8 rises to a certain level due to various reasons (such as overfilling, liquid expansion caused by temperature changes, etc.), the excess liquid will flow out through the overflow hole to prevent safety problems caused by excessively high liquid levels. The design and size of the overflow hole are usually determined according to the specific working conditions and safety requirements of the equipment to ensure that the excess liquid can be effectively discharged under normal working conditions, and at the same time, it can also play a role in protecting the processing machine under abnormal working conditions.

[0073] According to the embodiment of the utility model, the lifting oil tank EDM machine tool is provided. Figures 1 to 4 An oil tank is provided in the bed 1, and the base 2 is installed in the oil tank.

A vertical base 5 is provided on one side of the transverse slide 4, and a vertical slide rail is constructed on the vertical base 5, and the vertical slide 6 is slidably connected to the vertical slide rail. It can be seen from the above that the motion mechanism can realize three-dimensional motion in the transverse, longitudinal and vertical directions. At the same time, the vertical slide 6 is a box structure, and the bottom width of the box structure is relatively large, which can balance the lateral bending moment formed by the transverse slide 4, the vertical slide 6 and the functional components at the bottom of the vertical slide, and avoid the longitudinal slide 3 from pitching deformation during the movement.
