Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to a spindle box structure for a turning center. Background Technology

[0002] Currently, multi-axis CNC machine tools refer to those with X, Y, and Z axes of motion as well as workpiece rotation, and possess multiple independent spindles. Each independent spindle has its own independent control system, and multiple workpieces can be processed in each clamping. However, these multiple spindles are often arranged on one side, so only one side of the workpiece can be machined, and the machining accuracy cannot be guaranteed. Only rough machining of the workpiece is possible, and fine machining is not possible. The spindle box in a multi-axis CNC machine tool is one of the important components of the machine tool and is also the key to the machine tool's workpiece machining. Therefore, the spindle box is one of the important conditions for ensuring the accuracy, stability, durability, and overall rigidity of the machine tool.

[0003] In existing turning center spindle box structures, the lubricating oil between the spindle and bearings will condense due to the drop in temperature in cold regions or seasons. The condensed lubricating oil is prone to attracting dust and other contaminants, increasing friction and reducing lubrication effectiveness. Furthermore, due to the condensation of the lubricating oil, it is necessary to constantly add lubricating oil, which increases the amount of lubricating oil used. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a spindle box structure for a turning center, which solves the problem that in cold regions or during cold seasons, the lubricating oil between the spindle and bearings will solidify due to the drop in temperature. The solidified lubricating oil is prone to attracting dust and other contaminants, increasing friction and thus reducing the lubrication effect. Furthermore, due to the solidification of the lubricating oil, it is necessary to constantly add lubricating oil, which increases the amount of lubricating oil used.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spindle box structure for a turning center, comprising a housing, a cover rotatably connected to the top of the housing, a drive shaft rotatably connected to one side of the housing, a spindle body rotatably connected to one side of the housing, a drive gear fixedly connected to the surface of the drive shaft, a driven gear fixedly connected to the surface of the spindle body, the drive gear and the driven gear meshing, one end of the spindle body passing through the inner wall of the housing and extending to the front of the housing, a bearing fixedly connected to the surface of the housing, the spindle body rotatably connected to the inner wall of the bearing, and an anti-freezing mechanism located outside the bearing on the surface of the housing. In this invention, the drive shaft is driven to rotate by a motor on the equipment, and the drive gear on the drive shaft drives the spindle body to rotate via the driven gear. The anti-freezing mechanism prevents the lubricating oil between the spindle body and the bearing from freezing, thus preventing the lubricating oil from condensing when the equipment is used in extremely cold weather or regions.

[0008] Preferably, the antifreeze mechanism includes a housing, which is fixedly connected to the surface of the housing and is fitted over the bearing.

[0009] Preferably, heaters are fixedly connected to both sides of the inner side of the outer casing, and baffles are fixedly connected to the top wall of the inner side of the outer casing. Two baffles are provided, and the two baffles are respectively located on one side of the two heaters.

[0010] Preferably, the bottom of the outer casing is connected to a first connecting pipe, the output end of the first connecting pipe is fixedly connected to a micro pump, the output end of the micro pump is connected to a second connecting pipe, and the output end of the second connecting pipe is fixedly connected to the top of the outer casing.

[0011] Preferably, a filter plate is fixedly connected inside the outer shell. The filter plate is located on the bottom side of the bearing. In this invention, the filter plate can filter out impurities in the melted lubricating oil, which facilitates subsequent extraction and reuse, thus saving the use of lubricating oil.

[0012] Preferably, a cleaning port is provided on one side of the outer shell, and a door panel is snapped into the inside of the cleaning port. A handle is fixedly connected to the outer surface of the door panel. In this invention, impurities on the filter plate can be cleaned out through the cleaning port to prevent clogging of the filter plate and thus ensure its filtration effect.

[0013] Preferably, a locking block is fixedly connected to the side of the door panel, and a slot is formed on the surface of the outer shell. The slot is located on the side of the cleaning port, and the locking block is engaged inside the slot. A sealing ring is fixedly connected to the side of the door panel. In this invention, the locking block and slot facilitate the engagement and disengagement of the door panel and the outer shell, thereby facilitating the cleaning of impurities on the filter plate. Furthermore, the sealing ring seals the door panel and the cleaning port, preventing lubricating oil from flowing out of the cleaning port.

[0014] In this invention, when the antifreeze mechanism is working, the lubricating oil between the bearing and the main shaft is heated and melted by a heater, thereby improving the lubrication effect of the lubricating oil in cold weather and preventing the lubricating oil from solidifying and reducing the lubrication effect. After the melted lubricating oil is filtered by the filter plate, it enters the bottom of the inner shell. The micro pump is started, and the filtered lubricating oil enters the top of the inner shell through the first and second connecting pipes, and then flows back to the surface of the bearing. This allows the excess lubricating oil to be filtered and reused, saving lubricating oil and improving the lubrication effect.

[0015] (III) Beneficial Effects

[0016] This utility model provides a spindle box structure for a turning center. It has the following advantages:

[0017] (i) The spindle box structure of the turning center, through the setting of the antifreeze mechanism, uses a heater to heat and melt the condensed lubricating oil, and the outer shell provides a certain degree of heat preservation to prevent the lubricating oil between the spindle and the bearing from condensing and reducing its lubrication effect. This improves the lubrication effect and eliminates the need to add a large amount of lubricating oil, thus saving the use of lubricating oil.

[0018] (II) The spindle box structure of the turning center, through the setting of filter plate, micro pump, first connecting pipe and second connecting pipe, etc., when the micro pump is started, the filtered lubricating oil enters the top of the housing through the first connecting pipe and second connecting pipe, and then flows back to the surface of the bearing, so that the excess lubricating oil can be filtered and reused, saving the use of lubricating oil.

[0019] (III) The spindle box structure of the turning center, through the setting of door panel, cleaning port, clamping block and clamping groove, can easily connect and remove the door panel from the outer shell, thereby facilitating the removal of impurities on the filter plate, preventing the filter plate from clogging and thus ensuring the filtration effect of the filter plate.

Specifically, the drive shaft 3 is driven to rotate by a motor on the equipment, and the drive gear 5 on the drive shaft 3 drives the spindle 4 to rotate through the driven gear 6. The antifreeze mechanism 8 can prevent the lubricating oil between the spindle 4 and the bearing 7 from freezing, preventing the lubricating oil from condensing when the equipment is used in extremely cold weather or regions.

[0028] The antifreeze mechanism 8 includes a housing 81, which is fixedly connected to the surface of the housing 1 and is fitted over the bearing 7.

[0029] Heaters 82 are fixedly connected to both sides of the interior of the outer casing 81, and baffles 83 are fixedly connected to the top wall of the interior of the outer casing 81. There are two baffles 83, which are located on one side of the two heaters 82 respectively.

[0030] The bottom of the outer casing 81 is connected to a first connecting pipe 84, the output end of the first connecting pipe 84 is fixedly connected to a micro pump 85, the output end of the micro pump 85 is connected to a second connecting pipe 86, and the output end of the second connecting pipe 86 is fixedly connected to the top of the outer casing 81.

[0031] The housing 81 has a filter plate 87 fixedly connected inside. The filter plate 87 is located on the bottom side of the bearing 7. Specifically, the filter plate 87 can filter out impurities in the melted lubricating oil, making it convenient to extract and reuse it, thus saving the use of lubricating oil.

[0032] The outer casing 81 has a cleaning port 88 on one side, and a door panel 89 is snapped into the inside of the cleaning port 88. A handle is fixedly connected to the outer surface of the door panel 89.
