Description

Technical Field

[0001] The present application relates to the technical field of numerically controlled machine tools, and in particular to an oil leakage-proof numerically controlled machine tool. Background Art

[0002] In order to realize fully automatic control, modern CNC machine tools need to be equipped with hydraulic and pneumatic transmission devices in addition to the CNC system. The hydraulic transmission device is mainly equipped with a hydraulic pump and an oil tank. The oil in the oil tank, together with the cutting fluid and circulating water, plays the role of lubrication, cooling, filtering, separation of bubbles in the oil, precipitation of impurities, cleaning, and corrosion prevention during the CNC machine tool processing process, thereby improving the processing accuracy and work efficiency of the CNC machine tools. For those parts that require lubricating oil, special oil leakage prevention treatment is required.

[0003] Compared with the actual use process, one of the existing CNC machine tools in the spindle box in the machine tool is to use rubber to block the connection between the shaft and the box wall to prevent leakage by sealing. However, the rubber gasket itself has ductility, and after long-term use, the rubber gasket will become softer due to heat, thereby reducing the sealing and causing slow oil leakage.

[0004] Therefore, in order to solve the above problems, the present application provides an oil leakage-proof CNC machine tool.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0020] Embodiment 1

[0021] Reference Figure 1-Figure 4 , an oil leakage-proof CNC machine tool, comprising a machine tool body 1, a spindle box 2 is installed on one side of the top of the machine tool body 1, an input leakage-proof box 3 is welded on one end of the outer side of the spindle box 2, in order to collect the oil leakage at the power input end of the spindle box 2, an output leakage-proof box 4 is welded on the other end of the spindle box 2, in order to collect the oil leakage at the power output end of the spindle box 2, a transmission motor 5 is installed on the outer side of one end of the input leakage-proof box 3 at the top of the machine tool body 1 through a base, a partition plate 6 is welded in the middle of the inner side of the spindle box 2, in order to provide a driving gear rod 7 To provide stability, the middle of the partition 6 is rotatably connected to the inner side of the spindle box 2 with a driving gear rod 7, the meshing end of the driving gear rod 7 is rotatably connected to a low-speed driven gear rod 8 on one side of the spindle box 2, and the meshing end of the driving gear rod 7 is rotatably connected to a high-speed driven gear rod 9 on the other side of the spindle box 2. The other end of the driving gear rod 7 and the driving end of the transmission motor 5 are connected to the inner side of the input leak-proof box 3 through an electromagnetic coupler 10. In order to avoid the transmission end of the transmission motor 5 being directly connected to the driving gear rod 7, thereby causing oil leakage, the outer side of the spindle box 2 at one end is connected to the driving gear rod 7. The side surface is provided with two guide oil grooves 11 inside the output leak-proof box 4, and waste oil collection bins 12 are welded at the bottom of the input leak-proof box 3 and the output leak-proof box 4. In order to collect the leaked oil and prevent it from flowing to the outer surface of the equipment and causing pollution, the bottoms of the input leak-proof box 3 and the output leak-proof box 4 are connected to the top of the waste oil collection bin 12, and a discharge pipe 13 is connected to the bottom of one end of the waste oil collection bin 12. A milling cutter 14 is welded at one end of the low-speed driven gear rod 8 and the high-speed driven gear rod 9 on the outside of the output leak-proof box 4, and the transmission motor 5 drives the transmission. A bearing 15 is sleeved at the connection between the end and the wall of the spindle box 2, a bearing 15 is sleeved at the connection between the outer end of the active gear rod 7 and the partition 6 and the wall of the spindle box 2, and a bearing 15 is sleeved at the connection between the outer ends of the low-speed driven gear rod 8 and the high-speed driven gear rod 9 and the wall of the spindle box 2 and the output leak-proof box 4. The low-speed driven gear rod 8 and the high-speed driven gear rod 9 are both meshed with the active gear rod 7, and the tooth surface diameter of the low-speed driven gear rod 8 is larger than the tooth surface diameter of the high-speed driven gear rod 9, in order to make the rotation speeds of the two milling cutters 14 different.

[0022] Working principle: First, after the operator completes the installation of the equipment, during normal use, the operator starts the transmission motor 5. At that time, the transmission motor 5 will drive the active gear rod 7 to rotate through the electromagnetic coupler 10 at its transmission end, and the active gear rod 7 will drive the low-speed driven gear rod 8 and the high-speed driven gear rod 9 meshing therewith to rotate. Since the tooth surface diameter of the low-speed driven gear rod 8 is larger than the tooth surface diameter of the high-speed driven gear rod 9, the rotation speed of the low-speed driven gear rod 8 will be lower than the rotation speed of the high-speed driven gear rod 9. The rotating low-speed driven gear rod 8 and the high-speed driven gear rod 9 will drive the milling cutter 14 connected to the outer side of one end of the two to rotate, so that the parts fixed on the top side of the machine tool body 1 can be milled, and the rotation speed of the milling cutter can be selected according to needs;

[0023] During use, since the interior of the main spindle box 2 is connected to each other through gears, the interior of the main spindle box 2 is filled with sufficient lubricating oil in advance, and in order to prevent excessive friction during use, the outer sides of all rotating shafts that are connected to the walls of the main spindle box 2, the input leak-proof box 3 and the output leak-proof box 4 are sleeved with bearings 15, and the outer sides of the bearings 15 are sleeved with rubber gaskets. However, slow oil leakage will still occur during rotation. At that time, the oil leaked from the power output end of the main spindle box 2 will enter the output leak-proof box 4 through the guide oil groove 11 opened on the outer side of one end of the main spindle box 2, and then flow into the waste oil collection bin 12 through the bottom end of the output leak-proof box 4, thereby preventing the oil from flowing along the low-speed driven gear rod 8 The oil at the power input end of the spindle box 2 will flow into the waste oil collecting bin 12 through the bottom of the input leak-proof box 3, and finally be discharged to the outside through the discharge pipe 13 connected to the bottom of one end of the waste oil collecting bin 12 for unified collection. Moreover, since the transmission end of the transmission motor 5 and the active gear rod 7 are connected through the electromagnetic coupler 10, the oil will not flow along one end of the active gear rod 7 to the transmission end of the transmission motor 5, and thus flow to the outside. This design can completely collect the oil leaked from the device during use, and it will not flow to the outside and the surface of the machine tool, which can solve the problem of slow oil leakage in the traditional rubber leak-proof mechanism, thereby causing pollution to the outside of the equipment.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
