Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control machine tools, and more particularly, to a rapid cooling type numerical control machine tool capable of collecting scraps. BACKGROUND

[0002] Numerical control machine tools generate a large amount of scraps, including iron scraps, copper scraps, aluminum scraps, etc., during the machining process. The process of cleaning the scraps usually needs to be performed multiple times, and even requires the machine tool to stop machining, resulting in a reduction in production efficiency. At the same time, the cutting process of the machine tool generates a large amount of heat, which needs to be cooled and lubricated by cutting fluid. The cutting fluid can also clean and cool the workpiece.

[0003] During the machining process of the numerical control machine tool, cleaning the scraps and cooling are two necessary links, but they are often not effectively combined in actual operation, resulting in high energy consumption. Especially when the cutting fluid is recycled, the scraps are mixed with the cutting fluid, increasing the difficulty of recycling. In the prior art, the separation and cleaning of the scraps are monitored and controlled by manual or intelligent management systems. However, manual monitoring cannot clean the scraps in time, and manual operation needs to control the corresponding equipment for scrap cleaning and cutting fluid recycling, which is too labor-intensive and costly. Intelligent management can reasonably adjust the timing and method of cleaning, filtering, and cooling by monitoring the state and temperature of the machine tool in real time. However, this method not only consumes more energy, but also has higher development and equipment costs.

[0004] In view of this, the present application provides a rapid cooling type numerical control machine tool capable of collecting scraps. SUMMARY

[0021] The process of the water storage tank moving down to drive the upper support groove to move down can be divided into three stages. In the first stage, the plurality of lower filter plates rotate counterclockwise until a flat plate structure is formed, the upper filter module is always higher than the drainage plate, and the debris is continuously filtered. In the second stage, the plurality of upper filter plates rotate counterclockwise until a flat plate structure is formed, the lower filter module replaces the upper filter module to filter the debris, and after the upper filter plate is turned upside down, the separated debris is poured on the lower filter module, and the debris and cutting fluid generated by the tool unit also fall on the lower filter module through the gap between the upper filter plates. In the third stage, the upper filter module gradually approaches the lower filter module, and the debris on the lower filter module is extruded, and the debris and cutting fluid generated by the tool unit are trapped above the upper filter module. By setting the driving unit and the recovery unit, the self-adaptive cycle operation of debris filtering, extrusion and discharge is realized by using the gravity of the cutting fluid, and the debris filtering and discharge processes are separated to avoid mutual influence and improve the separation efficiency.

By driving one of the chain wheels two 3321 to rotate, the synchronous rotation of the plurality of lower filter plates 333 is realized.

[0042] When the plurality of lower filter plates 333 are rotated counterclockwise to be attached to each other, a flat plate structure is formed, the top surface of the lower filter plates 333 faces upward, and the bottom end of the lower filter plate 333 at the lowermost layer is attached to the drainage plate two 34. At this time, the lower filter module 33 can be used to separate the debris and the cutting fluid, wherein the cutting fluid is guided to the drainage cavity by the drainage plate two, and the debris is on the lower filter plate 333.

[0046] The recycling unit 6 includes a water storage tank 61, a drainage tank 62, and can also include a magnetic attraction structure 63. The water storage tank 61 is in communication with the separation tank 2 and is slidingly connected to the outer side of the separation tank 2. The bottom of the water storage tank 61 is provided with a drainage groove, and the drainage groove is provided with an elastic plate 611, and the elastic plate 611 covers the drainage groove. In other embodiments, the bottom surface of the elastic plate 611 can also be provided with a sealing gasket, and the elastic plate 611 covers the drainage groove and forms a sealing structure with the bottom surface of the water storage tank 61 when there is no external force.

[0047] The drainage tank 62 is located below the water storage tank 61, and a trigger rod 621 is fixedly connected in the drainage tank 62. When the water storage tank 61 slides downward, the trigger rod 621 is located on the moving path of the elastic plate 611. A drainage opening 622 is formed in the drainage tank 62. The drainage opening 622 can be connected to the water tank through a pipeline to recycle the cutting fluid into the water tank. In other embodiments, the cutting fluid can be further filtered and cooled before being guided into the water tank to realize the recycling of the cutting fluid.

[0048] The magnetic attraction structure 63 includes a magnetic force block 631 and a magnetic block 632 that are attracted to each other, and the magnetic force block 631 and the magnetic block 632 are fixedly connected to the water storage tank 61 and the separation tank 2, respectively. When the magnetic force block 631 and the magnetic block 632 are attracted, the bottom surface of the water storage tank 61 is higher than the top surface of the drainage tank 62.

In the initial stage, the magnetic block 632 is attracted to the magnetic attraction block, and the water storage tank 61 is suspended outside the separation tank 2. As the cutting fluid in the water storage tank 61 increases, the overall gravity of the water storage tank 61 overcomes the magnetic force, so that the water storage tank 61 slides downward, and after the magnetic block 632 is separated from the magnetic attraction block, the water storage tank 61 quickly falls until the trigger rod 621 contacts the elastic plate 611, the elastic plate 611 is opened upward, and the water in the water storage tank 61 flows into the drainage tank 62 through the drainage groove, and then is discharged outward through the drainage opening 622. In this process, the overall gravity of the water storage tank 61 decreases, and the trigger rod 621 plays a buffering role on the water storage tank 61, so that the downward movement speed of the water storage tank 61 decreases. The gravity of the downward movement of the water storage tank 61 acts on the driving unit 4 to drive the filtering unit 3.

[0050] Two driving units 4 are symmetrically installed on the outer wall of the separation tank 2. The driving unit 4 comprises a traction module 41, a transmission module 42. The transmission module 42 comprises a support shell 421, an elastic telescopic rod 422, a rack two 426, a gear one 423, a gear two 424, a rack one 425. The support shell 421 is fixedly connected to the outer wall of the separation tank 2 and communicates with the separation tank 2. A guide rail for slidingly connecting the upper support groove 311 is installed on the support shell 421. The lower support groove 331 is fixedly connected to the inner wall of the support shell 421. One end of the elastic telescopic rod 422 is fixedly connected to the upper support groove 311, and the other end is fixedly connected to the inner wall of the support shell 421, and the rack two 426 is fixedly connected to the outer wall of the elastic telescopic rod 422. The gear two 424 is installed on one of the sprocket two 3321 through the lower support groove 331, and the gear two 424 is located in the moving path of the rack two 426. The gear one 423 is installed on one of the sprocket one 3121 through the upper support groove 311, the rack one 425 is fixedly connected to the inner wall of the support shell 421, and the rack one 425 is located in the moving path of the gear one 423.

[0051] The traction module 41 comprises a traction rope 411, a pulley block 412, and the pulley block 412 is installed on the outer wall of the separation tank 2. One end of the traction rope 411 is fixedly connected to the outer wall of the water storage tank 61, and the other end is fixedly connected to the upper support groove 311 through the pulley block 412.

[0052] As the cutting fluid in the water storage tank 61 increases, the overall gravity of the water storage tank 61 overcomes the magnetic force of the magnetic attraction structure 63 and the elastic force of the elastic telescopic rod 422, and after the water storage tank 61 slowly descends for a distance, the magnetic force is greatly reduced due to the increase in the distance between the magnetic block 631 and the magnetic block 632, and then the water storage tank 61 begins to rapidly descend, and the upper support groove 311 is pulled downward by the traction rope 411 until the upper support groove 311 is close to the lower support groove 331.

[0053] Please refer to Figures 11-12 , wherein, Figure 10 Fig. a is a partial perspective view of the filtering unit 3 in the first stage; Figure 10 Fig. b is a partial perspective view of the filtering unit 3 in the second stage; Figure 10 Fig. c is a partial perspective view of the filtering unit 3 in the third stage. Figure 12 , Figure 14 , Figure 16 Figs. 1, 2 and 3 are partial structural schematic views of the driving unit 4 and the filtering unit 3 in the first, second and third stages, respectively, Figure 13 , Figure 15 Figs. 4 and 5 are intermediate state diagrams, respectively.

[0054] The lowering process of the upper support groove 311 can be divided into three stages. In the first stage, the rack two 426 first contacts the gear two 424, driving the gear two 424 to rotate, so that the plurality of lower filter plates 333 rotates counterclockwise until a flat plate structure is formed. In the first stage, the upper filter module 31 is always higher than the drainage plate one 32, continuously filtering the debris. In the second stage, the gear one 423 contacts the rack one 425, and under the action of the rack one 425, the gear one 423 rotates counterclockwise, so that the plurality of upper filter plates 313 rotates counterclockwise until a flat plate structure is formed. In the second stage, the lower filter module 33 replaces the upper filter module 31 to filter the debris, and after the upper filter plates 313 are turned downward, the separated debris is poured on the lower filter module 33, and the debris and cutting fluid generated by the tool unit 102 also fall through the gap between the upper filter plates 313 and fall on the lower filter module 33. In the third stage, the upper filter module 31 gradually approaches the lower filter module 33 to extrude the debris on the lower filter module 33, and the debris and cutting fluid generated by the tool unit 102 are trapped above the upper filter module 31.

[0055] When the cutting fluid in the water storage tank 61 is discharged outward through the drain groove until the overall gravity of the water storage tank 61 is less than the elastic force of the elastic expansion rod 422, the water storage tank 61 begins to rise, and the cutting fluid inside the water storage tank 61 continues to flow outward until it is completely discharged. Then the rising speed of the water storage tank 61 increases until the magnetic block 631 and the magnetic block 632 are completely attracted. During the upward movement of the water storage tank 61, the upper support groove 311 moves to the initial position, and in this process, the upper filter module 31 first rotates clockwise to form a stepped structure, and the trapped debris falls on the lower filter module 33 and is separated by the lower filter module 33. Subsequently, the upper filter module 31 rotates clockwise to form a stepped structure, and in this process, the debris falls into the debris discharge cavity under the action of gravity and then is concentrated in the debris collection drawer 23 through the debris discharge chute 22.

[0056] To sum up, the numerical control machine tool of the embodiment adopts the cooling unit to cool the tool head, and guides the scraps and cutting fluid generated in the working process into the separation box 2. By setting the filtering unit 3, the scraps are separated from the cutting fluid, and the cutting fluid is recycled by the recycling unit 6, so as to reduce the loss of the cutting fluid. In the recycling process of the cutting fluid, the water tank is lowered to drive the traction rope 411 to pull down the upper supporting groove 311, so as to extrude the separated scraps under the premise of maintaining the filtering of the scraps, reduce the space occupied by the scraps, and improve the recycling efficiency of the scraps. In the process of lowering, the water storage tank 61 opens the drainage groove by the trigger rod 621 in the drainage tank 62 to drain the cutting fluid in the water storage tank 61, and the water storage tank 61 is pulled back to the initial position by the elastic telescopic rod 422. The lowering and resetting of the water storage tank 61 are not powered, and the automatic separation of the scraps is realized without external power, without manual supervision, greatly reducing the energy consumption, and without the control program, reducing the research and development cost and the equipment cost.

Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application.
