Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machine tool equipment, and specifically relates to a cooling system for a numerical control machine tool. Background Art

[0002] With the development of numerical control technology, high-speed and high-precision numerical control machine tool processing has replaced a lot of manual processing. The improvement of the processing difficulty and precision of workpieces not only drives the transformation of processing technology, but also leads to the popularization and rapid development of coolant. Machine tool processing utilizes the relative movement between the tool and the workpiece to cause elastic and plastic deformation of the workpiece to achieve the purpose of metal processing. During the processing process, due to the friction between the tool and the workpiece, a large amount of heat will be generated in the processing area. If this heat is not dissipated in time, the tool and the workpiece will be damaged, which will not only reduce the service life of the tool, but also affect the processing precision and surface roughness of the workpiece. Therefore, the cooling effect of the machine tool tool cooling system is of decisive significance to the processing quality, processing efficiency of workpieces and the service life of tools, etc.

[0003] During the numerical control machine tool processing, media such as coolant are usually used to cool and lubricate the tool and the workpiece, and at the same time, it also plays roles such as anti-corrosion and chip flushing. In the traditional numerical control machine tool during workpiece processing, the coolant is often turned on to align the pipeline with the processed workpiece for workpiece cooling. However, the coolant is sprayed at the same speed and cannot be automatically adjusted according to the level of processing heat, so it cannot ensure better cooling when it is hotter, and the surface quality of the workpiece is locally unstable.

One end of the operation box 15 is connected to a shunt pipe 18 through a second connecting pipe 17. Two nozzles 27 are symmetrically installed on the outer walls at both the left and right ends of the shunt pipe 18. Retaining rings 28 are fixedly installed on the inner sides at both the left and right ends of the shunt pipe 18. One end of the retaining ring 28 is connected to a baffle 29 through a torsion spring; A bottom plate 33 is fixedly installed on one side wall of the operation console 1. A slide rail 34 is slidably connected to the bottom plate 33. A movable pipe 21 is installed on the upper end of the slide rail 34 in a liftable manner.

A thermometer (not shown in the figure) can be installed on one side at the upper end of the support pipe 20. The thermometer can rotate on the movable pipe 21 together with the support pipe 20 and the shunt pipe 18.

[0023] One end of the connecting pipe 14 is inserted into the operating platform 1 and fixedly installed with a filter head, and the other end communicates with the inside of the operating box 15. The upper end of the operating box 15 is fixedly installed with a control panel 16. One end of the connecting pipe 17 is connected to the inside of the operating box 15, and the other end is fixedly connected to the connection port 26 on the shunt pipe 18. A coolant storage tank and two water pumps are provided in the operating box 15. The connecting pipe 14 communicates with the coolant storage tank. Both water pumps are connected to the coolant storage tank through water pipes. The liquid outlet pipes of both water pumps are connected to a three-way through water pipes. The other end of the three-way is fixedly connected to one end of the connecting pipe 17. One-way valves are installed on both water pipes. The water pumps and the temperature measuring instrument are both electrically connected to the control panel 16.

[0024] The upper end of the retaining ring 28 is rotatably connected to the baffle 29 through a torsion spring. A sealing gasket 30 is fixedly installed on the inner end side wall of the baffle 29. The sealing gasket 30 is in contact with one end of the retaining ring 28. The baffle 29 is located between two adjacent nozzles 27. When the torsion spring is in a balanced state, the sealing gasket 30 seals the retaining ring 28, so that the nozzles 27 at the outermost sides of both ends of the shunt pipe 18 do not spray coolant.

[0025] The bottom plate 33 is L-shaped. One end of the bottom plate 33 away from the slide rail 34 is threadedly connected with a threaded rod 35. The lower end of the fixed cylinder 31 is slidably connected to the slide rail 34 through a slider. One end of the threaded rod 35 passes through the side wall of one end of the bottom plate 33 and is rotatably connected to one end of the fixed cylinder 31. The lower end of the moving pipe 21 is slidably inserted into the fixed cylinder 31. A hand-tightening bolt 32 is threadedly connected to the side wall of one end of the fixed cylinder 31. The inner end of the hand-tightening bolt 32 is in contact with the side wall of one end of the moving pipe 21. By screwing the hand-tightening bolt 32, the length of the moving pipe 21 inserted into the fixed cylinder 31 can be adjusted, so as to adjust the height of the shunt pipe 18 and the nozzles 27.

[0026] A number of anti-slip strips are evenly and fixedly installed on the outer wall of the support pipe 20. The lower end of the support pipe 20 is inserted into the inner side of the moving pipe 21. One end of the moving pipe 21 is slidably inserted into the pin 22. A clamping plate 25 is fixedly installed at the inner end of the pin 22. The clamping plate 25 is arc-shaped. A number of anti-slip strips are evenly and fixedly installed on the outer wall of the clamping plate 25. The clamping plate 25 is clamped with the outer wall of the support pipe 20. A spring 23 is sleeved on the outer side wall of the outer end of the pin 22. A pull ring 24 is fixedly installed on the outer side wall of the outer end of the pin 22. Two fixing plates 19 are provided at the upper end of the support pipe 20. The fixing plates 19 are arc-shaped. The two fixing plates 19 are fixedly connected by bolts. The shunt pipe 18 is located between the two fixing plates 19. One of the fixing plates 19 is fixedly connected to the upper end of the support pipe 20 to fix the shunt pipe 18. When the spring 23 is in a balanced state, the anti-slip strips on the clamping plate 25 are engaged with the anti-slip strips on the support pipe 20. By pulling the pull ring 24 outward, the pull ring 24 drives the clamping plate 25 to move outward by compressing the spring 23 and separates from the support pipe 20, and then the support pipe 20 can be rotated to adjust the angles of the shunt pipe 18 and the nozzle 27 for spraying the coolant.

[0027] When the device works, the operating table 1 is installed at one end of the numerical control machine tool, and the parts to be processed are fixed on the workbench 12. The height and angle of the shunt pipe 18 are adjusted so that the nozzles 27 and the temperature measuring instrument on the shunt pipe 18 face the parts and the tool. Then, a water pump is started through the control panel 16. The water pump inputs the coolant into the shunt pipe 18. Since the pressure generated by one water pump is not enough to push open the baffle 29, the coolant is sprayed onto the parts and the tool through the two nozzles 27 inside the shunt pipe 18 for cooling and lubrication. The tool on the numerical control machine tool is started to turn the parts, and the temperature measuring instrument monitors the real-time temperature of the parts and the tool. The temperature detected by the temperature measuring instrument is transmitted to the control panel 16. When the temperature transmitted to the control panel 16 is higher than the temperature value of the highest temperature preset in the control panel 16 in advance, the control panel 16 starts another water pump to work, increases the pressure in the shunt pipe 18, and pushes open the baffle 29. The other two nozzles 27 also spray the coolant onto the parts and the tool. When the temperature transmitted by the temperature measuring instrument to the control panel 16 is higher than the temperature value of the lowest temperature preset in the control panel 16 in advance, the control panel 16 turns off one of the water pumps. It is also possible to manually turn on and off the two water pumps through the control panel 16.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
