Description

Technical Field

[0001] This utility model relates to the field of lubricating oil heat dissipation technology, specifically a circulating heat dissipation device for lubrication of machine tool gearboxes. Background Technology

[0002] The machine tool's spindle is located inside the gearbox, which is used to achieve high and low speed changes and provide varying cutting forces. Multiple gear pairs inside the gearbox mesh with the gears on the spindle to achieve these changes. Because the gears rotate at high speed, friction between them generates high temperatures, requiring cooling and lubrication. Therefore, a large amount of machine oil is added to the gearbox and comes into contact with the gears.

[0003] Existing cooling devices for machine tool gearbox lubrication often suffer from blockage of cooling pipes due to impurities in the lubricating oil, and the surface of the heat sink is prone to accumulating a large amount of dust, affecting the heat dissipation efficiency of the heat sink to the cooling pipe. Therefore, they do not meet the current requirements. To address this, we propose a circulating cooling device for machine tool gearbox lubrication. Utility Model Content

[0004] The purpose of this utility model is to provide a circulating heat dissipation device for lubrication of machine tool gearboxes, so as to solve the problems mentioned in the background art, such as the heat dissipation device for lubrication of machine tool gearboxes often being blocked by impurities in the lubricating oil, and the heat dissipation fins being prone to a large amount of dust adhering to the surface, which affects the heat dissipation efficiency of the heat dissipation fins to the heat dissipation fins.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating heat dissipation device for lubrication of a machine tool gearbox, comprising a fixed plate, a plurality of heat dissipation fins fixedly installed on the front side of the fixed plate, and lubricating oil pipes arranged in an S-shape penetrating the surface of the heat dissipation fins, with an oil inlet pipe at one end of the lubricating oil pipe and an oil outlet pipe at the other end, both the oil inlet pipe and the oil outlet pipe having a filter mechanism at their ends, a front baffle fixedly installed on the front side of the heat dissipation fins, and a heat dissipation port on the surface of the front baffle, with a cooling fan rotatably installed inside the heat dissipation port.

[0006] Preferably, the filtration mechanism includes an upper filter box, a lower filter box, a discharge port, and a filter screen. The lower filter box can be detachably installed at the bottom of the upper filter box. Both the upper and lower filter boxes are equipped with filter screens. The bottom of the lower filter box is equipped with a discharge port. The oil inlet pipe and the oil outlet pipe are connected to the interior of the upper and lower filter boxes. The bottom of the discharge port is equipped with a pressure relief valve.

[0007] Preferably, one of the upper and lower filter boxes has a circulation outlet on its outer side, and the other of the upper and lower filter boxes has a circulation inlet on its outer side.

[0008] Preferably, both sides of the front baffle are provided with lifting grooves. A lead screw is rotatably installed inside the lifting groove on one side, and a guide rod is provided inside the lifting groove on the other side. A movable rod is movably installed between the lead screw and the guide rod. The movable rod is connected to the surface of the lead screw through a lead screw movable sleeve. A flexible brush is provided on the side of the movable rod near the heat sink.

[0009] Preferably, a servo motor is provided at the top of the lead screw, and the output end of the servo motor is connected to the lead screw through a coupling.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the cooperation of the lead screw and the movable rod, enables the device to be used by starting the servo motor, which drives the lead screw to rotate, thereby driving the movable rod to rise and fall. This allows the flexible brush on the surface of the movable rod to clean the dust on the surface of the heat sink and the lubricating oil pipe, thus preventing the heat sink and the lubricating oil pipe from accumulating a large amount of dust after long-term use, which would affect the heat dissipation efficiency of the lubricating oil.

[0013] 2. This utility model, through the cooperation of the upper and lower filter boxes, allows the lubricating oil in the machine tool gearbox to be transported through the circulation outlet to the interior of the first upper and lower filter boxes during use. The lubricating oil is then filtered through the internal filter screens, preventing impurities from clogging the lubricating oil pipes. Simultaneously, after the lubricating oil cools, it is transported again through the oil outlet pipe to the interior of the second upper and lower filter boxes for a second filtration, preventing impurities from flowing back into the machine tool gearbox and affecting its operation. When it is necessary to remove the impurities filtered by the upper and lower filter boxes, the pressure relief valve can be opened to discharge the lubricating oil from the upper and lower filter boxes. The filter boxes can then be disassembled for replacement or maintenance of the filter screens, thus extending the service life of the lubricating oil. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 An embodiment of this utility model provides a circulating heat dissipation device for lubrication of a machine tool gearbox, including a fixed plate 1. A plurality of heat sinks 2 are fixedly installed on the front side of the fixed plate 1. Lubricating oil pipes 6 arranged in an S-shape pass through the surface of the heat sinks 2. One end of the lubricating oil pipe 6 is provided with an oil inlet pipe 7, and the other end of the lubricating oil pipe 6 is provided with an oil outlet pipe 8. Both the oil inlet pipe 7 and the oil outlet pipe 8 are provided with a filter mechanism. A front baffle 3 is fixedly installed on the front side of the heat sinks 2. The surface of the front baffle 3 is provided with a heat dissipation port 4, and a cooling fan 5 is rotatably installed inside the heat dissipation port 4.

[0021] By cooperating with the heat sink 2 and the lubricating oil pipe 6, the device first draws out the lubricating oil from the machine tool gearbox through the circulation outlet 17, and then lets it enter the interior of the lubricating oil pipe 6 through the oil inlet pipe 7, so that the heat sink 2 can dissipate the heat. At the same time, the cooling fan 5 is started, so that the cooling fan 5 can perform air cooling on the heat sink 2 and the lubricating oil pipe 6, thereby improving the heat dissipation efficiency.

[0022] The filtration mechanism includes an upper filter box 9, a lower filter box 10, a discharge port 15, and a filter screen 16. The lower filter box 10 can be detachably installed at the bottom of the upper filter box 9. Both the upper filter box 9 and the lower filter box 10 are equipped with filter screens 16. The bottom of the lower filter box 10 is equipped with a discharge port 15. The oil inlet pipe 7 and the oil outlet pipe 8 are connected to the interior of the upper filter box 9 and the lower filter box 10. The bottom of the discharge port 15 is equipped with a pressure relief valve.

[0023] One of the upper filter boxes 9 and the lower filter box 10 has a circulation outlet 17 on its outer side, and the other upper filter box 9 and the lower filter box 10 has a circulation inlet 18 on its outer side.

[0024] By cooperating with the upper filter box 9 and the lower filter box 10, the device allows the lubricating oil in the machine tool gearbox to be transported through the circulation outlet 17 to the interior of the first upper filter box 9 and the lower filter box 10 during operation. The lubricating oil is then filtered through the internal filter screen 16, preventing impurities from clogging the lubricating oil pipe 6. Simultaneously, after the lubricating oil cools, it is transported again through the oil outlet pipe 8 to the interior of the second upper filter box 9 and the lower filter box 10 for a second filtration, preventing impurities from flowing back into the machine tool gearbox and affecting its operation. When it is necessary to process the impurities filtered inside the upper filter box 9 and the lower filter box 10, the pressure relief valve can be opened to discharge the lubricating oil. The upper filter box 9 and the lower filter box 10 can then be disassembled to replace or maintain the filter screen 16, thus extending the service life of the lubricating oil.

[0025] The front baffle 3 has lifting slots on both sides. A lead screw 12 is rotatably installed inside one of the lifting slots, and a guide rod 14 is installed inside the other lifting slot. A movable rod 13 is movably installed between the lead screw 12 and the guide rod 14. The movable rod 13 is connected to the surface of the lead screw 12 through a lead screw movable sleeve. A flexible brush is provided on the side of the movable rod 13 near the heat sink 2.

[0026] Through the cooperation of lead screw 12 and movable rod 13, when the device is in use, the servo motor 11 is started, which drives the lead screw 12 to rotate. The lead screw 12 then drives the movable rod 13 to rise and fall, so that the flexible brush on the surface of the movable rod 13 can clean the dust on the surface of the heat sink 2 and the lubricating oil pipe 6. This prevents the heat sink 2 and the lubricating oil pipe 6 from accumulating a lot of dust after the device has been used for a long time, which would affect their heat dissipation efficiency for lubricating oil.

[0027] A servo motor 11 is provided at the top of the lead screw 12, and the output end of the servo motor 11 is connected to the lead screw 12 through a coupling.

[0028] Both the outer ends of the circulation outlet 17 and the circulation inlet 18 are connected to the machine tool gearbox.

[0029] When in use, the circulating cooling device for lubrication of the machine tool gearbox first draws the lubricating oil from the gearbox through the circulation outlet 17, allowing it to enter the lubricating oil pipe 6 through the oil inlet pipe 7. The oil is then cooled by the heat sink 2. Simultaneously, the cooling fan 5 is activated to provide air cooling to the heat sink 2 and the lubricating oil pipe 6, thereby improving cooling efficiency.

[0030] In use, the servo motor 11 can be started to drive the lead screw 12 to rotate, which in turn drives the movable rod 13 to rise and fall. This allows the flexible brush on the surface of the movable rod 13 to clean the dust from the heat sink 2 and the lubricating oil pipe 6, thus preventing a large amount of dust from accumulating on the surface of the heat sink 2 and the lubricating oil pipe 6 after prolonged use, which would affect the heat dissipation efficiency of the lubricating oil.

[0031] When the lubricating oil in the machine tool gearbox is first transported to the first upper filter box 9 and lower filter box 10 through the circulation outlet 17, it can be filtered by the internal filter screen 16 to prevent impurities in the lubricating oil from clogging the lubricating oil pipe 6. At the same time, after the lubricating oil has cooled down, it will be transported again to the second upper filter box 9 and lower filter box 10 through the oil outlet pipe 8, thus performing a second filtration of the lubricating oil to prevent impurities from flowing back into the machine tool gearbox and affecting its operation. When it is necessary to treat the impurities filtered inside the upper filter box 9 and lower filter box 10, the pressure relief valve can be opened to discharge the lubricating oil inside the upper filter box 9 and lower filter box 10. The upper filter box 9 and lower filter box 10 can be disassembled to replace or maintain the filter screen 16, thereby improving the service life of the lubricating oil.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
