Technical Field
[0001] This invention relates to the field of electrical discharge machining equipment, and in particular to a three-sided lifting device for the liquid tank of an electrical discharge machine. Background Technology
[0002] Electrical discharge machining (EDM), a highly precise and unique machining process, is based on the ingenious use of electro-erosion to perform fine machining on various workpieces. In the complex yet orderly process of EDM, the liquid tank plays a crucial role. This tank is specifically designed to store the working fluid, ensuring a continuous and stable supply during the machining process. Only when the workpiece is completely immersed in the working fluid can a stable and reliable medium environment be created for the EDM discharge, guaranteeing a smooth discharge process. Simultaneously, the working fluid can effectively and promptly remove debris generated during machining, preventing debris accumulation from negatively impacting machining accuracy and efficiency, thus ensuring high-quality completion of the EDM process.
[0003] However, in the existing technology, it has been found that the liquid tank of traditional EDM machines usually adopts a single-sided lifting drive, that is, one end of the liquid tank is driven by a guide rail and a lifting device, while the other end is suspended in the air. During the lifting process, the suspended end is prone to shaking due to gravity or driving force fluctuations. After long-term use, the liquid tank may tilt and deform due to uneven force, resulting in a shortened service life. Moreover, it is difficult to ensure the overall level of the working fluid in the liquid tank, which makes it easy for the working fluid in the liquid tank to splash out or for the liquid level to be inconsistent, affecting the consistency of processing. Summary of the Invention

At the same time, it affects the overall level of the working fluid in the liquid tank, which may cause the working fluid in the liquid tank to splash out or the liquid level to be inconsistent, affecting the consistency of processing.

Beneficial effects
[0025] In summary, this application includes at least one of the following beneficial technical effects: This invention provides a three-sided lifting device for the liquid tank of an EDM machine. By incorporating components such as a slide rail, slider, and threaded rod, a drive motor rotates a first sprocket. Through the connection of the first sprocket, chain, and second sprocket, a rotating rod, a first bevel gear, and a second bevel gear rotate. Simultaneously, the threaded rod rotates, causing a nut to rise and fall, thereby lifting the liquid tank body from the lifting seat. The slider slides along the slide rail until the liquid tank body reaches its highest point and engages with the fixed frame to form a containment area. This device, through its three-sided guiding and synchronous drive design, improves the stability and levelness of the liquid tank body during lifting, solving the instability and low precision problems caused by traditional single-sided lifting. It also makes the liquid tank body more compact, effectively reducing the space occupied by the igniter.
[0026] This invention provides a three-sided lifting device for an EDM liquid tank. By incorporating components such as an industrial camera, an L-shaped tube, a magnetic levitation guide rod assembly, and a float sensing unit, the device works by having the fixed frame and the liquid tank body cooperate to form an enclosed area. The controller controls the industrial camera to capture images of the workpiece on the worktable surface and transmits these images to the controller for analysis. At this point, the inlet pump is activated, drawing working fluid from the conical storage tank through a first pipe and injecting it into the liquid tank body through a second pipe and a branch inlet pipe. The working fluid then enters the L-shaped tube through a connecting pipe, causing the float sensing unit to float along the magnetic levitation guide rod assembly. The magnetic levitation guide rod assembly detects the height of the float sensing unit, and the controller controls this height until the float sensing unit reaches a designated height. The controller then shuts off the inlet pump to stop the injection, completing the filling of the working fluid. At this point, the liquid level is above the workpiece by a certain height. This allows the device to control the liquid level at the optimal processing height based on the workpiece height, preventing the liquid level from being too high or too low, thereby improving processing accuracy, reducing processing errors, and enhancing the surface finish of the workpiece.
[0027] This invention provides a three-sided lifting device for an EDM liquid tank. By incorporating a conical liquid storage tank, a third pipe, a threaded connection, and a filter cylinder, after the workpiece is processed, a solenoid valve is opened via a controller, allowing the working fluid inside the liquid tank to drain out. The working fluid then enters the threaded connection through the third pipe and is ultimately filtered by the filter cylinder. This ensures that impurities generated during processing are retained inside the filter cylinder, thus reducing impurities in the working fluid within the conical liquid storage tank. Furthermore, the threaded connection between the threaded connection and the third pipe facilitates easy removal and cleaning of the filter cylinder. The conical shape of the liquid storage tank allows impurities to settle to the bottom, preventing them from being drawn out by the inlet pump and the first pipe, thereby reducing impurities in the working fluid and preventing any impact on processing quality.

When the working fluid enters the L-shaped tube 37 through the connecting pipe 36, the working fluid level inside the L-shaped tube 37 becomes level with the working fluid level inside the liquid tank body 6, allowing the float sensing unit 39 to slide up to the liquid level height. The height of the float sensing unit 39 is monitored in real time by the magnetic levitation guide rod assembly 38.
[0036] Reference Figure 8 , Figure 9 and Figure 10 A liquid inlet pump 40 is fixedly installed on the upper surface of the fixed plate 24. A first pipe 41 is fixedly installed at the input end of the liquid inlet pump 40, and a second pipe 42 is fixedly installed at the output end of the liquid inlet pump 40. A diversion inlet pipe 43 is fixedly connected to the top end of the second pipe 42, and the top end of the diversion inlet pipe 43 is fixedly connected to the inner bottom wall of the liquid tank body 6. The liquid inlet pump 40 is installed on the upper surface of the fixed plate 24, and the first pipe 41 is set at the output end of the liquid inlet pump 40 so that the liquid inlet pump 40 and the first pipe 41 can draw the working fluid inside the conical storage tank 25. The second pipe 42 is installed at the output end of the liquid inlet pump 40, and the diversion inlet pipe 43 is set at the top end of the second pipe 42 to divert the working fluid inside the conical storage tank 25. The liquid pipe 43 is connected to the bottom of the liquid tank body 6, so that the working fluid drawn by the inlet pump 40 can be poured into the interior of the liquid tank body 6 through the second pipe 42 and the diversion inlet pipe 43 to complete the filling of the working fluid. The inner bottom wall of the liquid tank body 6 is fixedly connected to the diversion outlet pipe 44, and the bottom surface of the diversion outlet pipe 44 is fixedly connected to the third pipe 45. The outer surface of the third pipe 45 is fixedly installed with a solenoid valve 46. The other end of the third pipe 45 is threadedly connected to a threaded connection part 47. The left end of the threaded connection part 47 is fixedly connected to a filter cylinder 48. The diversion outlet pipe 44 is installed on the inner bottom wall of the liquid tank body 6, and the third pipe 45 is installed on the lower half of the diversion outlet pipe 44. On the outer surface of the third pipe 45, the opening and closing of the solenoid valve 46 is controlled, allowing the third pipe 45 to open and close. A threaded connection 47 is installed at the end of the third pipe 45, and a filter cartridge 48 is installed at the left end of the threaded connection 47. The filter cartridge 48 facilitates the separation of impurities in the working fluid. The threaded connection between the threaded connection 47 and the third pipe 45 facilitates the removal and cleaning of the filter cartridge 48, thereby reducing impurities in the working fluid inside the conical storage tank 25. The industrial camera 35, the magnetic levitation guide rod assembly 38, the inlet pump 40, and the solenoid valve 46 are all electrically connected to the controller 29. Valve 46 is connected to controller 29, enabling controller 29 to analyze images captured by industrial camera 35 to determine the height of the highest point of the workpiece. The detection data of magnetic levitation guide rod assembly 38 can be transmitted to controller 29 in real time. When the liquid level reaches the specified height, controller 29 controls the liquid inlet pump 40 to shut down and stop liquid injection. By analyzing the captured workpiece images and by setting up magnetic levitation guide rod assembly 38 and float sensing unit 39, the liquid level height can be detected in real time and transmitted to controller 29 for analysis. This allows the liquid level to be controlled at the optimal processing height according to the workpiece height, preventing the liquid level from being too high or too low, improving processing accuracy, reducing processing errors, and improving the surface processing quality of the workpiece.
[0037] It should be noted that linear modules are provided between the bed 1, the machine tool body 3, and the spindle box 22 to realize the forward and backward and lateral feed of the spindle box 22. The magnetic levitation guide rod assembly 38 is composed of a guide rod and a magnetic coupling system. When the float sensing unit 39 moves up and down along the magnetic levitation guide rod assembly 38, the magnetic coupling system converts the position of the float sensing unit 39 into a readable signal, thereby realizing the detection of liquid level. The second pipe 42 is a flexible hose that can be bent when the liquid tank body 6 moves up and down to complete the liquid filling operation of the liquid tank body 6.
[0038] The implementation principle of this application embodiment is as follows: First, the workpiece to be processed is placed on the surface of the workbench 2. Then, the drive motor 9 is started to drive the first sprocket 10 to rotate. Through the connection of the first sprocket 10, the chain 11, and the second sprocket 12, the rotating rod 13 can rotate. The rotating rod 13 drives the first bevel gear 14 to rotate. Through the connection of the first bevel gear 14 and the second bevel gear 15, the threaded rod 16 is rotated. Through the connection of the threaded rod 16 and the nut 17, the lifting seat 18 drives the liquid tank body 6 to rise. At this time, the liquid tank body 6 drives the slider 7 to rise along the slide rail 5 until the liquid tank body 6 rises to the highest position. At this time, the first elastic seal 3... The first elastic seal 30 and the second elastic seal 33 are adapted to the groove on the bottom surface of the mounting frame 31, so that the liquid tank body 6 and the fixing frame 4 form an enclosure area, and the sealing is completed by the first elastic seal 30 and the second elastic seal 33. This allows the device to improve the stability and levelness of the liquid tank body 6 during the lifting process through the three-sided guiding and synchronous drive design, solving the problems of instability and low precision caused by traditional single-sided lifting. At the same time, it makes the liquid tank body 6 more compact and effectively reduces the space occupied by the igniter. Then, the controller 29 controls the industrial camera 35 to collect images of the workpiece to be processed on the surface of the worktable 2 and transmits them to the controller 29 for analysis. After completion, the inlet pump 40 is started, drawing the working fluid from the conical storage tank 25 through the first pipe 41, and then injecting it into the liquid tank body 6 through the second pipe 42 and the diversion inlet pipe 43. Due to the connection between the connecting pipe 36 and the L-shaped pipe 37, the working fluid enters the L-shaped pipe 37 synchronously. At this time, the float sensing unit 39 rises along the magnetic levitation guide rod assembly 38. The magnetic coupling system converts the position of the float sensing unit 39 into a readable signal and transmits it to the controller 29 in real time. When the liquid level reaches the specified height, the controller 29 controls the inlet pump 40 to stop injecting liquid, so that the device can control the liquid level at the optimal processing height according to the height of the workpiece, preventing the liquid level from rising too high. The temperature is adjusted to improve machining accuracy, reduce machining errors, and improve the surface finish of the workpiece. The workpiece is then machined by the spindle head module 23. After machining, the solenoid valve 46 is opened by the controller 29. The used working fluid is then discharged through the diversion outlet pipe 44 and finally filtered by the filter cartridge 48 before flowing back into the conical storage tank 25. The filter cartridge 48 completes the filtration of the working fluid, reducing the flow of impurities into the conical storage tank 25. After the working fluid has been used for a period of time, the drain valve 27 is opened to allow the working fluid and precipitated impurities inside the conical storage tank 25 to be discharged and treated uniformly through the drain pipe 26.
