Description

Technical Field

[0001] This utility model relates to the field of vertical slide table technology, specifically a vertical slide table for a milling and turning composite machine tool. Background Technology

[0002] Vertical slides are key components of mill-turning machines. In mill-turning machining, vertical slides can drive the cutting tool or workpiece to make precise vertical lifting movements. They work in conjunction with other axes of the machine tool, enabling the cutting tool to reach different positions on the workpiece and complete various complex machining processes. However, existing vertical slides are difficult to achieve self-lubricating function, and long-term use will lead to wear on the transmission mechanism.

[0003] Patent document CN213702465U discloses a vertical slide table for a milling and turning composite machine tool. It mainly focuses on designing a vertical slide table suitable for high-rigidity, high-precision, and short-stroke machining of a milling and turning composite machine tool, but does not consider how to self-lubricate the transmission mechanism to reduce friction and wear. Utility Model Content

[0004] The purpose of this invention is to provide a vertical slide table for a milling and turning machine tool, in order to solve the problem that existing vertical slide tables are difficult to self-lubricate, and long-term use will lead to wear of the transmission mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical slide table for a milling and turning composite machine tool, comprising a vertical slide table body, a slide groove inside the vertical slide table body, a motor box mounted on the top of the vertical slide table body, a control motor mounted inside the motor box, a lead screw mounted on the output end of the control motor, a fixing block mounted inside the slide groove, a through hole inside the fixing block located outside the lead screw, a miniature electric actuator mounted inside the fixing block, the miniature electric actuator located in front of the through hole, and an arc-shaped plate mounted on the output end of the miniature electric actuator.

[0006] Preferably, a guide rod is installed inside the slide groove, the guide rod is located behind the lead screw, and a slider is sleeved on the outer surface of the guide rod and the lead screw. A worktable is installed at one end of the slider, the worktable is located in front of the vertical slide body, and a cleaning brush is installed at the bottom of the slider for cleaning the lead screw.

[0007] Preferably, an oil storage tank is provided inside the top wall of the vertical slide body, and a channel is connected to the back of the oil storage tank, with one end of the channel located directly above the arc plate.

[0008] Preferably, the top and bottom of the slider are equipped with protective covers, and guide rails are provided on both outer walls of the vertical slide body.

[0009] Preferably, movable blocks are installed on the inner walls of both ends of the workbench, the movable blocks are located inside the guide rail, and protective covers are installed on the top and bottom of the movable blocks.

[0010] Preferably, the top wall of the vertical slide body is provided with a liquid inlet channel, one end of which is connected to the top of the oil storage tank, and a sealing plug is installed inside the liquid inlet channel.

[0011] Preferably, a mounting plate is installed at the bottom of the vertical slide body, and a reinforcing rib is installed at the top of the mounting plate, with the reinforcing rib located at the back of the vertical slide body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model periodically activates a miniature electric actuator to push the arc-shaped plate and sponge pad closer to the lead screw, so that the sponge pad comes into contact with the lead screw. At this time, the lubricating oil on the sponge pad will adhere to the surface of the lead screw and flow downward along the groove of the lead screw, thereby achieving a self-lubricating function, reducing friction and wear, and ensuring the smoothness and accuracy of the lead screw transmission.

[0014] 2. In this invention, while the slider moves, the cleaning brush moves along the groove of the lead screw to clean the dust in the groove. By self-cleaning the lead screw, dust and debris are effectively prevented from accumulating in the groove, which improves the motion accuracy of the device to a certain extent and extends its service life. At the same time, during the up and down movement of the worktable, the protective covers 1 and 2 located above and below the worktable expand and contract with the movement of the worktable to prevent dust, chips and other debris from entering the slide and guide rail, affecting the motion accuracy and service life of the lead screw, and reducing the impact of external factors on the slide table.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An embodiment of this utility model provides a vertical slide table for a milling and turning composite machine tool, comprising a vertical slide table body 1, a slide groove 5 inside the vertical slide table body 1, a motor box 3 installed on the top of the vertical slide table body 1, a control motor 4 installed inside the motor box 3, a lead screw 7 installed at the output end of the control motor 4, a fixing block 14 installed inside the slide groove 5, a through hole 15 inside the fixing block 14, the through hole 15 being located outside the lead screw 7, a miniature electric actuator 19 installed inside the fixing block 14, the miniature electric actuator 19 being located in front of the through hole 15, and an arc plate 16 installed at the output end of the miniature electric actuator 19;

[0025] An oil storage tank 13 is provided inside the top wall of the vertical slide body 1. A channel is connected to the back of the oil storage tank 13, and one end of the channel is located directly above the arc plate 16.

[0026] Lubricating oil is added to the oil reservoir 13 for storage. The lubricating oil in the oil reservoir 13 drips from the channel to the arc-shaped plate 16 directly below. A sponge pad is installed on the inner surface of the arc-shaped plate 16. The lubricating oil is absorbed by the sponge pad. The micro electric actuator 19 is activated periodically to push the arc-shaped plate 16 and the sponge pad closer to the lead screw 7, so that the sponge pad comes into contact with the lead screw 7. At this time, the lubricating oil on the sponge pad will adhere to the surface of the lead screw 7 and flow downward along the groove of the lead screw 7. When lubrication is not required, the arc-shaped plate 16 is stored in the through hole 15 and continues to absorb the lubricating oil from the oil reservoir 13, thereby achieving a self-lubricating function, reducing friction and wear, and ensuring the smoothness and accuracy of the lead screw 7 transmission. The sponge pad has a strong adsorption capacity and can effectively absorb and store lubricating oil. When lubrication is required, it slowly releases the internally stored lubricating oil and distributes the absorbed lubricating oil evenly on the surface of the lead screw 7 to continuously lubricate the lead screw 7. After absorbing the lubricating oil, the sponge pad can also play a buffering role, reducing the impact force between components and preventing lubricating oil leakage.

[0027] A guide rod 6 is installed inside the slide 5. The guide rod 6 is located behind the lead screw 7. A slider 8 is sleeved on the outer surface of the guide rod 6 and the lead screw 7. A worktable 2 is installed at one end of the slider 8. The worktable 2 is located in front of the vertical slide body 1. A cleaning brush 9 is installed at the bottom of the slider 8. The cleaning brush 9 is used to clean the lead screw 7.

[0028] The control motor 4 runs, driving the lead screw 7 to rotate, causing the slider 8 to move along the direction of the guide rod 6, thereby moving the worktable 2 up and down. At the same time as the slider 8 moves, the cleaning brush 9 moves along the groove of the lead screw 7 to clean the dust in the groove. By self-cleaning the lead screw 7, dust and debris are effectively prevented from accumulating in the groove of the lead screw 7, which improves the motion accuracy of the device to a certain extent and extends the service life of the device.

[0029] The top and bottom of the slider 8 are equipped with protective covers 10, and the outer walls on both sides of the vertical slide body 1 are provided with guide rails 12.

[0030] Movable blocks are installed on the inner walls of both ends of the workbench 2. The movable blocks are located inside the guide rail 12. Protective covers 11 are installed on the top and bottom of the movable blocks.

[0031] Both protective cover 10 and protective cover 2 11 are foldable. During the up-and-down movement of the worktable 2, protective cover 10 and protective cover 2 11 located above and below the worktable 2 expand and contract with the movement of the worktable 2. When the worktable 2 moves up, the upper protective cover 10 and protective cover 2 11 shorten, while the lower protective cover 2 11 and protective cover 10 extend, preventing dust, chips and other debris from entering the slide groove 5 and guide rail 12, affecting the movement accuracy and service life of the lead screw 7, and reducing the impact of external factors on the slide table.

[0032] The top wall of the vertical slide body 1 is provided with a liquid inlet channel 18. One end of the liquid inlet channel 18 is connected to the top of the oil storage tank 13. A sealing plug 17 is installed inside the liquid inlet channel 18.

[0033] A mounting plate 20 is installed at the bottom of the vertical slide body 1, and a reinforcing rib 21 is installed at the top of the mounting plate 20. The reinforcing rib 21 is located on the back of the vertical slide body 1.

[0034] After adding lubricating oil into the oil storage tank 13 through the inlet channel 18, the sealing plug 17 is inserted into the inlet channel 18 to achieve a seal and prevent lubricating oil from splashing out of the inlet channel 18, thus avoiding resource waste. The mounting plate 20 is used to install and fix the vertical slide body 1. The mounting plate 20 is fixed in the turning and milling compound machine tool with anti-loosening bolts for easy installation and disassembly. At the same time, the reinforcing rib 21 further improves the overall rigidity of the slide. After installation, operation can be carried out. The external workpiece fixture is installed on the front of the worktable 2, and the workpiece is clamped between the fixtures. The workpiece slides up and down through the cooperation of the control motor 4, lead screw 7, slider 8 and worktable 2 to perform precision machining.

[0035] Working principle: The mounting plate 20 is fixed inside the milling and turning machine tool using anti-loosening bolts. An external workpiece fixture is installed on the front of the worktable 2 to clamp the workpiece between the fixtures. The motor 4 is controlled to run, driving the lead screw 7 to rotate, causing the slider 8 to move along the direction of the guide rod 6, thereby moving the worktable 2 and the workpiece up and down. While the slider 8 is moving, the cleaning brush 9 moves along the groove of the lead screw 7 to clean the dust in the groove. The protective covers 10 and 11 located above and below the worktable 2 expand and contract with the movement of the worktable 2 to prevent dust, chips and other debris from entering the slide groove 5 and guide rail 12. The micro electric actuator 19 is periodically activated to push the arc plate 16 and the sponge pad closer to the lead screw 7, so that the sponge pad comes into contact with the lead screw 7. At this time, the lubricating oil on the sponge pad will adhere to the surface of the lead screw 7 and flow downward along the groove of the lead screw 7. When lubrication is not required, the arc plate 16 is retracted into the through hole 15 and continues to absorb the lubricating oil from the oil reservoir 13, thereby achieving the self-lubricating function.

Those skilled in the art can understand and implement this without any creative effort.

[0037] 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.
