Description

Technical Field

[0001] This utility model relates to the field of machine tool processing lubrication technology, specifically a micro-lubrication device. Background Technology

[0002] Micro-volume lubrication systems are devices used in mechanical equipment to provide precise and small amounts of lubricating oil. Their main purpose is to reduce friction and wear, while improving mechanical efficiency and extending equipment lifespan. Micro-volume lubrication systems typically use specialized pumps, nozzles, or piping systems to precisely deliver lubricating oil to the parts requiring lubrication. Micro-volume lubrication technology is widely used in metal cutting, stamping, injection molding, and other industrial fields. Currently, micro-volume lubrication systems are used on machine tools to lubricate workpieces during machining. Since lubrication does not affect secondary use after a single use, it is usually recycled. However, the lubricating oil after a single use contains metal shavings, which, if not filtered, can easily affect the effectiveness of subsequent uses. Therefore, precise control of the amount of lubricating oil applied to the workpiece is crucial. Improper control can lead to unnecessary cost waste, and insufficient quantity may result in inadequate lubrication, thus reducing the effectiveness of the micro-volume lubrication system and indirectly affecting machining efficiency.

[0003] Therefore, it is necessary to develop micro-lubrication devices. Utility Model Content

[0004] The purpose of this invention is to provide a micro-lubrication device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a micro-lubrication device, including a cutting machine tool, wherein side plates are installed on both sides of the top of the cutting machine tool, and guide columns are provided at the front and rear ends of the two sets of side plates on opposite sides, and a base is installed at the bottom of the cutting machine tool, wherein a water tank is installed on one side of the bottom of the base.

[0006] A lubrication component is installed on the other side of the inner bottom of the base. The lubrication component includes a pump body, and a water inlet pipe is installed on the water inlet end of the pump body.

[0007] Preferably, a discharge hopper is installed at the top of the interior of the base, and the top of the discharge hopper is in a through-hole with the bottom of the cutting machine tool.

[0008] Preferably, the water tank has limit posts on both sides inside, and a filter plate is installed above the limit posts. The outer wall of the filter plate is slidably connected to the inside of the water tank.

[0009] Preferably, handles are provided on both sides of the top of the filter plate, a side box is installed on the upper part of one side of the outer wall of the water tank, and fixing plates are provided on the lower part of the inner walls on both sides of the side box.

[0010] Preferably, a filter frame is installed inside the lower part of the side box, the filter frame is located between two sets of fixed plates on opposite sides, and a drain pipe is provided on the lower part of the other side outer wall of the water tank.

[0011] Preferably, one end of the water inlet pipe is fixedly connected to the lower side of the outer wall of the water tank, and a flexible hose is installed at the water outlet end of the pump body.

[0012] Preferably, a central tube is installed at one end of the hose, and a movable seat is installed on the outer wall of the central tube. Guide holes are provided at both the front and rear ends of the surface of the movable seat.

[0013] Preferably, the inner wall of the guide hole is slidably connected to the outer wall of the guide post, an electric valve is installed below the outer wall of the central tube, and a spray head is installed at the bottom end of the central tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By sliding the filter plate inside the water tank and placing a filter frame inside the side box on one side of the outer wall of the water tank, the lubricating oil and metal shavings generated during the cutting of the workpiece by the machine tool are discharged from the unloading hopper onto the surface of the filter plate and then filtered by the filter plate. The filtered metal shavings fall into the filter frame along the tilt angle and are then cleaned up. This method minimizes the possibility of the lubricating oil containing metal shavings affecting the processing in the later secondary recycling process.

[0016] By sliding the movable seat onto the outer wall of the guide column on the cutting machine tool through the guide hole, and connecting the hose on the pump body to the central tube on the movable seat, the opening and closing status and flow control can be set in the background according to the electric valve on the outer wall of the central tube. When the workpiece is being processed in the cutting machine tool, the position between the movable seat and the workpiece is adjusted, the pump body draws lubricating oil from the water tank and delivers it to the central tube, and then the electric valve is controlled according to the opening and closing status and flow control set in the background. Finally, the oil is sprayed by the spray head, achieving micro-volume lubrication operation. This avoids the situation where too much or too little lubricating oil is used, which would cause cost waste or failure to achieve the lubrication effect. This effectively improves the use effect of the micro-lubrication device and indirectly improves the processing efficiency. Attached Figure Description

[0023] 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.

[0024] This utility model provides the following technical solution: a micro-lubrication device; please refer to [link / reference]. Figures 1-5The machine tool includes a cutting machine tool 1. Side plates 101 are installed on both sides of the top of the cutting machine tool 1. Guide posts 102 are provided at the front and rear ends between opposite sides of the two sets of side plates 101. A base 2 is installed at the bottom of the cutting machine tool 1. A discharge hopper 201 is installed at the top of the base 2, and the top of the discharge hopper 201 is connected to the bottom of the cutting machine tool 1. A water tank 3 is installed on one side of the bottom of the base 2. The water tank 3 installed inside the base 2 at the bottom of the cutting machine tool 1 stores the lubricating oil used for cutting lubrication. Inside water tank 3, for easy direct extraction later, limit posts 301 are set on both sides of the interior of water tank 3. A filter plate 302 is installed above the limit posts 301. The outer wall of the filter plate 302 is slidably connected to the interior of water tank 3. Handles 303 are set on both sides of the top of the filter plate 302. When the two sets of limit posts 301 are set in the interior of water tank 3 with the left side higher than the right side, the filter plate 302 is placed in the water tank 3 in a sliding manner. Due to the influence of the height of the two sets of limit posts 301, the filter plate 302 is placed in the water tank 3. The water tank 3 is tilted. A side box 304 is installed on the upper part of one outer wall. Fixing plates 305 are installed on the lower part of the inner walls on both sides of the side box 304. A filter frame 306 is installed inside the lower part of the side box 304, located between the two sets of fixing plates 305 on opposite sides. A drain pipe 307 is installed on the lower part of the other outer wall of the water tank 3. The side box 304 is installed on one outer wall of the water tank 3, and the filter frame 306 is slidably pushed into the interior of the side box 304 between the two sets of fixing plates 305, so that... During the machining process of the cutting machine tool 1, the lubricating oil used, along with the metal shavings produced during machining, is discharged from the unloading hopper 201 onto the surface of the filter plate 302, where it is filtered. The filtered metal shavings fall into the filter frame 306 at an inclined angle and are then cleaned up. This process aims to avoid the possibility of metal shavings in the lubricating oil being reused later, which could affect the machining process. Meanwhile, the lubricating oil in the water tank 3, once it can no longer be used, is discharged through the drain pipe 307.

[0025] A lubrication component is installed on the other side of the inner bottom of the base 2. The lubrication component includes a pump body 4. A water inlet pipe 401 is installed on the water inlet end of the pump body 4. One end of the water inlet pipe 401 is fixedly connected to the lower side of the outer wall of the water tank 3. A hose 402 is installed on the water outlet end of the pump body 4. The water inlet end of the pump body 4 used for the micro-lubrication device is connected to the water tank 3 through the water inlet pipe 401, and the hose 402 is installed at the water outlet end, so that the pump body 4 can draw the lubricating oil pre-stored in the water tank 3 and deliver it to the hose 402. Inside the machine tool 1, a central tube 403 is installed at one end of the hose 402. A movable seat 404 is installed on the outer wall of the central tube 403. Guide holes 405 are opened at both the front and rear ends of the movable seat 404. The inner wall of the guide hole 405 is slidably connected to the outer wall of the guide post 102. An electric valve 406 is installed below the outer wall of the central tube 403. A spray head 407 is installed at the bottom end of the central tube 403. The movable seat 404 is slidably connected to two sets of guide posts 102 through the guide holes 405. At the outer wall of the guide column 102, the hose 402 on the pump body 4 is connected to the central tube 403 on the moving seat 404. According to the electric valve 406 on the outer wall of the central tube 403, the opening and closing status and flow control can be set in the background. When the workpiece is processed in the cutting machine tool 1, the position between the moving seat 404 and the workpiece is adjusted to solve the stability problem of the moving seat 404. It is necessary to install an anti-slip ring in the guide hole 405 on the moving seat 404. According to the anti-slip effect of the anti-slip ring, the movement flexibility of the moving seat 404 is reduced, but it does not affect the movement effect of the moving seat 404. After the moving seat 404 has moved to the correct position, the pump body 4 draws lubricating oil from the water tank 3 and delivers it to the central tube 403. Then, the electric valve 406 controls the opening and closing status and flow control in the background. Finally, the spray head 407 sprays the oil. This achieves micro-control operation of lubricating oil and avoids the situation of excessive or insufficient lubricating oil control, which would cause cost waste or failure to achieve the lubrication effect.

[0026] Working Principle: When using this invention, a water tank 3 is installed inside the base 2 at the bottom of the cutting machine tool 1. The lubricating oil used for cutting is stored in the water tank 3 for easy extraction later. Two sets of limiting posts 301 are positioned with the left side higher than the right side inside the water tank 3, allowing the filter plate 302 to slide inside. Due to the height difference of the two sets of limiting posts 301, the filter plate 302 is tilted after placement. A side box 304 is installed on one outer wall of the water tank 3, and the filter frame 306 is slidably pushed into the side box 304. Two sets of fixing plates 305 are then installed between the side box and the filter plate 305. During the machining process of the cutting machine tool 1, the lubricating oil used, along with the metal shavings produced, is discharged from the unloading hopper 201 onto the surface of the filter plate 302, where it is filtered. The filtered metal shavings fall into the filter frame 306 at an inclined angle and are then cleaned. This process aims to minimize the possibility of metal shavings in the lubricating oil being reused later, which could affect the machining process. The pump body 4 of the micro-lubrication device is connected to the water tank 3 via an inlet pipe 401, and a hose 402 is installed at the outlet, allowing the pump body 4 to draw water into the pre-stored water tank 3. The lubricating oil is delivered into the hose 402. The movable seat 404 is slidably connected to the outer wall of the two sets of guide columns 102 on the cutting machine tool 1 via the guide hole 405. The hose 402 on the pump body 4 is connected to the central tube 403 on the movable seat 404. The opening and closing status and flow control can be set in the background according to the electric valve 406 on the outer wall of the central tube 403. When the workpiece is being processed in the cutting machine tool 1, the position between the movable seat 404 and the workpiece is adjusted. To solve the stability problem of the movable seat 404, an anti-slip ring needs to be fitted inside the guide hole 405 on the movable seat 404. The anti-slip effect of the ring reduces the flexibility of the moving seat 404, but does not affect the moving effect of the moving seat 404. After the moving seat 404 has moved to the correct position, the pump body 4 draws the lubricating oil from the water tank 3 and delivers it to the central pipe 403. Then, the electric valve 406 controls the opening and closing status and flow rate according to the background settings. Finally, the spray head 407 sprays the oil, achieving micro-control operation of lubricating oil. This avoids the situation where too much or too little lubricating oil is used, which would cause cost waste or failure to achieve the lubrication effect. This effectively improves the use effect of the micro-lubrication device and indirectly improves the processing efficiency.
