Description

Technical Field

[0001] The invention relates to the technical field of turning processing, in particular to a numerically controlled turning machine tool for processing fasteners. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used, such as bolts, nuts, washers, rivets, etc. These are metal fasteners, and turning machines are required during the processing and manufacturing process. Turning is an important metal processing method that uses a rotating turning tool to cut the workpiece to achieve the required shape, size and surface accuracy.

[0003] A tool holder column is usually set inside a turning machine tool. The tool holder column is used to support and stabilize the tool holder and allow it to move within a certain range in order to change the position of the tool. The tool holder column is usually thick and smooth, and the tool holder slides on the surface of the tool holder column. Therefore, the surface of the tool holder column is coated with lubricating oil, but these lubricating oils are often sticky. The metal chips generated during the turning process fall on the top and side of the tool holder column and are easily stuck to the lubricating oil. If these metal chips are pushed to move during the movement of the tool holder, friction is generated, which can easily wear the surface of the tool holder column. Long-term use can easily make the surface of the tool holder column become bumpy, so the surface of the tool holder column needs to be cleaned. At present, some mechanical equipment such as machine tools have been equipped with cleaning functions, such as brushes, brushes or push plates, to clean the surface of the rails or tool holder columns. However, the cleaning components are in direct contact with the tool holder columns and are easily contaminated by lubricating oil, which reduces the cleaning effect. In addition, the cleaning components need to use rotation, movement and other methods to push the metal chips on the surface of the tool holder column away. The metal chips will move slightly on the surface of the tool holder column under the push of the cleaning components, and will easily cause friction with the surface of the tool holder column. In addition, the cleaned metal chips often carry oil stains, which adhere to the metal chips, reducing the recovery value of the metal chips and making recycling inconvenient. Summary of the invention

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention turns on the square electromagnet, and when the tool holder body moves, the metal chips on the top and side of the tool holder column body are adsorbed on the surface of the magnetic synchronous belt, so as to avoid the magnetic synchronous belt, a cleaning component, from being directly in contact with the tool holder column body and being contaminated over a large area. In the process of adsorbing the metal chips, the metal chips will not be allowed to move slightly on the surface of the tool holder column body, so that it is not easy to cause wear to the tool holder column body, thereby extending the service life of the tool holder column body. After the turning work is completed, the square electromagnet is turned off to allow the magnetic synchronous belt to use its own suction to adsorb the metal chips, and at the same time, the pump body and the driving motor are turned on. The driving motor drives the roller to rotate through the transmission rod, the first rotating rod and the second rotating rod, so that the magnetic synchronous belt drives the metal chips into the cleaning box, and the treatment liquid sprayed by the scraper and the nozzle is used to wash away a small amount of oil and metal chips on the surface of the magnetic synchronous belt, so as to prevent the magnetic synchronous belt from being contaminated by a small amount of oil carried on the surface of the metal chips.

[0024] 2. The present invention drives the elliptical wheel to rotate through the transmission rod, and combines the cooperation of the slide rod, the walking wheel and the first spring to make the transverse tube swing up and down, so that the treatment liquid and the metal chips can fully contact when flowing inside the transverse tube, thereby realizing vibration cleaning, improving the cleaning effect of the metal chips, reducing the oil stains in the recovered metal chips, and facilitating the subsequent recovery work.

[0025] 3. The present invention uses the pump body to make the liquid flowing inside the vertical cylinder drive the piston to rise during the liquid supply process, and drives the vertical rod, the fixed plate, and the first rack to rise, cooperate with the first gear and the first rotating shaft, and make the through holes on the surface of the blocking plate align with the vertical cylinder to maintain the passage, and make the filter screen plate horizontal inside the liquid storage tank to filter and intercept the metal chips that flow back through the third hose, so that the metal chips no longer follow the circulation. At the same time, after the cleaning is completed, the pump body stops supplying liquid, and the vertical cylinder lacks the pressure from the liquid. Under the action of the second spring, the fixed plate, the first rack and the piston are lowered, thereby driving the filter screen plate to flip and turn upside down inside the storage box, and discharge the metal chips into the collection box. After the cleaning work is completed, the metal chips on the surface of the filter screen plate can also be discharged in time, which is convenient for subsequent recovery. At the same time, the upper blocking plate also follows to disconnect the passage inside the vertical cylinder to prevent some residual liquid and metal chips from flowing back when the filter screen plate is flipped and discharged.

The magnetic synchronous belt 6 adopts a new type of polymer magnetic auxiliary agent, which has the characteristics of strong magnetism and high metal adsorption force, and the magnetism is not easy to disappear. The direction of the magnetic synchronous belt 6 is roughly the same as the shape of the cover shell 5. A fixing plate 9 is bolted to the side of the tool holder body 3 close to the cover shell 5, and a square electromagnet 8 is bolted to the surface of the fixing plate 9.

There is one electromagnet on each side of the tool holder column body 2, and the direction of the square electromagnet 8 on the upper side faces downward, and the directions of the square electromagnets 8 on both sides face the sides of the tool holder column body 2. A fixing frame 10 is bolted to the bottom of the seat body 3, and a driving motor 11 is also bolted to the bottom of the knife seat body 3. A transmission rod 12 is fixed to the output shaft of the driving motor 11, and the transmission rod 12 passes through the fixing frame 10 and is rotatably connected to the penetration point thereof. A first rotating rod 13 is also rotatably connected to one side of the cover shell 5, and one end of the first rotating rod 13 is also rotatably connected to the knife seat body 3. The first rotating rod 13 and the transmission rod 12 are connected through a belt drive. A cleaning box 17 is fixed to the other side of the surface of the knife seat body 3. A notch is provided at the top of the cleaning box 17 for the magnetic synchronous belt 6 to enter. A partition 16 is also bolted to the inside of the cleaning box 17, and an auxiliary roller 7 is also provided inside the cleaning box 17.

[0044] During operation, the tool holder body 3 moves along the tool holder column body 2, and the machine tool starts turning the workpiece, and the generated metal chips fall on the surface of the tool holder column body 2. Since there is lubricating oil on the surface of the tool holder column body 2, some chips adhere to the side of the tool holder column body 2, but not the bottom. During the movement of the tool holder body 3, the square electromagnet 8 is turned on, which generates a strong magnetic field, passes through the magnetic synchronous belt 6, and generates a strong suction force, so that the metal chips on the surface of the tool holder column body 2 are adsorbed on the surface of the magnetic synchronous belt 6, and the metal chips fly out of the surface of the tool holder column body 2, so that the metal chips fall off the surface of the tool holder column body 2 and avoid direct contact with the tool holder column body 2, which not only prevents scratches caused by pushing the chips during the cleaning process, but also can avoid the magnetic synchronous belt 6 The surface of the tool holder 3 is stained with a lot of oil, and only a small amount of oil on the surface of the metal chips is adsorbed on the surface of the magnetic synchronous belt 6 along with the metal chips themselves. The surface of the magnetic synchronous belt 6 close to the top of the tool holder column body 2 and the two sides of the magnetic synchronous belt 6 close to the tool holder column body 2 are all adsorbed with metal chips under the action of the square electromagnet 8. After the processing is completed, the square electromagnet 8 is turned off, and the magnetic synchronous belt 6 firmly adsorbs the metal chips on the surface by its own adsorption force. The tool holder body 3 is reset to a position away from the chuck 4, and then the drive motor 11 is turned on. The output shaft of the drive motor 11 drives the transmission rod 12 to rotate. The transmission rod 12 drives the first rotating rod 13 and the second rotating rod 15 to rotate through the belt, so that the two sets of rollers 14 rotate synchronously, which makes the rollers 14 rotate clockwise (with a rotation speed of 200 rpm). Figure 6 Perspective mainly), thereby driving the magnetic synchronous belt 6 to run, and driving the metal chips adsorbed on the surface to move toward the inside of the cleaning box 17.

[0045] The liquid spraying mechanism 18 comprises a pump body 181, a delivery pipe 182 and a first solenoid valve 183. The pump body 181 is bolted to the bottom of the inner wall of the casing 1.

The surface of the liquid inlet 26 is provided with a sealing cover 28. The sealing cover 28 adopts a threaded inner wall and a threaded connection with the surface of the liquid inlet 26, so that the sealing cover 28 can be opened or closed. Adding heavy oil cleaning agent as a treatment liquid to the inside of the liquid storage tank 19 through the liquid inlet 26 can effectively remove oil stains on the metal surface and the surface of the conveyor belt. The added liquid level does not exceed the height of the filter screen plate 21. The first solenoid valve 183 is installed on the surface of the delivery pipe 182.

Under the reaction force of the second spring 237, the fixed plate 236, the vertical rod 235 and the piston 234 are subjected to a downward reaction force. Before the liquid enters the vertical cylinder 184, the position of the piston 234 is lower than the connection between the first hose 185 and the vertical cylinder 184. The fixed plate 236 and the first rack 233 are bolted to each other, and the first rotating shaft 231 and the filter screen plate 21 are bolted to each other.

[0047] When the magnetic synchronous belt 6 drives the adsorbed metal to move to the inside of the cleaning box 17, the pump body 181 and the first solenoid valve 183 are opened, which allows the treatment liquid in the liquid storage tank 19 to enter the inside of the vertical cylinder 184 through the delivery pipe 182. Under the subsequent squeezing of the treatment liquid, the piston 234 moves upward, and drives the vertical rod 235 and the fixed plate 236 to rise, so that the second spring 237 is in a compressed state. At the same time, the position of the piston 234 is higher than the connection between the first hose 185 and the vertical cylinder 184, so that the treatment liquid can enter the first hose 185, and the fixed plate 236 can drive the first rack 233 to rise, and drive the first gear 232 to rotate counterclockwise (with Fig.10The first rotating shaft 231 rotates counterclockwise, driving the filter screen plate 21 to lie horizontally inside the liquid storage tank 19 to filter the refluxed liquid.

[0048] After the treatment liquid passes through the first hose 185 and the U-shaped tube 186, the treatment liquid is sprayed from the nozzle 188 onto the surface of the magnetic synchronous belt 6 to wash away the metal chips adsorbed by the magnetic synchronous belt 6. At the same time, the treatment liquid can also remove a small amount of oil stains on the surface of the magnetic synchronous belt 6 or the metal chips. If some metal chips cannot be washed away by the treatment liquid sprayed from the lower row of nozzles 188, the upper scraper 187 intercepts the metal chips and prevents them from continuing to move with the magnetic synchronous belt 6. At the same time, the treatment liquid sprayed from the upper nozzle 188 is in the contact part between the scraper 187 and the magnetic synchronous belt 6, so it is easy to wash away the metal chips. Then the metal chips and the treatment liquid flow to the bottom of the cleaning box 17.

The reflux mechanism 22 also includes an elliptical wheel 226 bolted to the surface of the transmission rod 12. A sliding sleeve 229 is also bolted to the surface of the fixing frame 10. A sliding rod 2210 is slidably provided on the inner wall of the sliding sleeve 229. A walking wheel 2210 is bolted to the top of the sliding rod 2210. 27, a first spring 228 is fixed to the top of the sliding sleeve 229, the top of the first spring 228 is in contact with the bottom of the walking wheel 227, the first spring 228 is a compression spring, the first spring 228 is sleeved on the surface of the sliding rod 2210, the first spring 228 applies an upward reaction force to the walking wheel 227, so that the walking wheel 227 fits on the surface of the elliptical wheel 226, the bottom end of the sliding rod 2210 is also bolted to a frame plate 2211, a connecting column 2212 is welded on the surface of the transverse tube 222 close to the frame plate 2211, and the connecting column 2212 is slidably connected to the inner wall of the frame plate 2211, and the end of the transverse tube 222 away from the second hose 221 is connected to the third hose 2213, and the other end of the third hose 2213 is connected to the vertical cylinder 231 3 are interconnected. When the magnetic synchronous belt 6 continues to run and drives the metal chips into the cleaning box 17 and is washed down by the treatment liquid, the metal chips and the treatment liquid flow to the bottom of the cleaning box 17 and enter the transverse tube 222 through the second hose 221. At the same time, the transmission rod 12 can drive the elliptical wheel 226 to rotate. When the long radius end of the elliptical wheel 226 contacts the walking wheel 227, it can make the walking wheel 227 and the sliding rod 2210 descend, and make the first spring 228 in a compressed state. The sliding rod 2210 drives the frame plate 2211 to descend, and the frame plate 2211 drives the connecting column 2212 and one end of the transverse tube 222 to descend. The rotation center of the transverse tube 222 is the rotating column 224. At the same time, the short radius end of the elliptical wheel 226 contacts the connecting column 224. When the running wheels 227 contact each other, the running wheels 227 and the sliding rod 2210 rise, and drive the frame plate 2211 to rise, and drive the connecting column 2212 and one end of the horizontal tube 222 to rise, so that the end of the horizontal tube 222 close to the third hose 2213 is repeatedly lifted and lowered, shaking the treatment liquid and metal chips passing inside, realizing vibration cleaning, so that the treatment liquid can fully rinse the metal chips in the reflux process, and improve the cleaning effect. After that, the treatment liquid and metal chips pass through the third hose 2213, the vertical cylinder 2313 and the through hole 2316 and enter the interior of the liquid storage tank 19. The filter screen plate 21 is horizontally placed inside the liquid storage tank 19, and the treatment liquid and metal chips fall on the surface of the filter screen plate 21, and the filter screen plate 21 intercepts the metal chips.The treated liquid can pass through the filter screen 21 and return to the lower part of the liquid storage tank 19. The drive motor 11 is continuously turned on to allow the device to flush, recycle, and filter the metal chips adsorbed on the surface of the magnetic synchronous belt 6, and reuse the treated liquid.

[0050] After the cleaning is completed, the pump body 181 and the drive motor 11 are turned off. At this time, the pump body 181 no longer supplies liquid, and there is no more flowing liquid in the vertical cylinder 184 to push the piston 234. Under the reaction force of the second spring 237, the fixed plate 236, the vertical rod 235 and the piston 234 are lowered, thereby driving the first rack 233 to descend together. The piston 234 descends to a height lower than the connection between the first hose 185 and the vertical cylinder 184. The first rack 233 descends, which can drive the first gear 232 and the first rotating shaft 231 to rotate clockwise (with a rotation speed of 0.045 W). Fig.10 The filter screen 21 rotates toward the inside of the storage box 20 until it is inverted inside the storage box 20, and uses the inertia force during the rotation to throw out the metal chips, which fall downward. The lower part of the storage box 20 is slidably connected to the collection box 24, and the metal chips fall into the collection box 24, so that the metal chips are separated from the circulation of the treatment liquid. At this time, the metal chips have been cleaned and degreased, which is convenient for the staff to take for recycling. At the same time, the first rotating shaft 231 can drive the second rotating shaft 239 and the second gear 2310 to rotate in the clockwise direction during the clockwise rotation, and drive the blocking plate 2315 to rotate horizontally through the second rack 2311. The outside of the box 2314 moves so that the through hole 2316 is misaligned with the vertical cylinder 2313, disconnecting the passage and preventing the residual liquid and metal chips in the third hose 2213 and the horizontal tube 222 from flowing back into the storage box 20 during the pouring process of the filter screen plate 21. These residual metal chips can be left until the next cleaning operation is carried out and discharged. The surface of the storage box 20 is also rotatably connected to a rotating plate 25. When the rotating plate 25 rotates to the bottom, it blocks the collection box 24 to prevent it from being easily taken out. After the work is completed, the rotating plate 25 is rotated upward to release the obstruction to the collection box 24, and then the collection box 24 is taken out to recycle the metal chips inside.

[0051] The liquid outlet end of the pump body 181 is also connected to a drain pipe 189 through a three-way interface. The three-way interface here is respectively connected to the delivery pipe 182, the liquid outlet end of the pump body 181 and the drain pipe 189. A second solenoid valve 1810 is installed on the surface of the drain pipe 189. If the processing liquid inside the liquid storage tank 19 needs to be replaced, just close the first solenoid valve 183 and open the second solenoid valve 1810, then open the pump body 181, and place a container above the liquid storage tank 19 and below the end of the drain pipe 189. The internal processing liquid is discharged from the liquid storage tank 19 through the drain pipe 189 and enters the container. The container is taken out of the casing 1 to discharge the processing liquid, and then the sealing cover 28 is opened, and new processing liquid is added through the liquid inlet 26, and then the sealing cover 28 is covered; the surface of the tool holder column body 2 away from the chuck 4 is blocked by the large-volume tool holder body 3 during the turning process, and metal chips generally do not fall on the other side.

[0052] The present invention achieves the adsorption of metal chips during the entire cleaning process, and washes, vibrates, cleans, recycles, filters the metal chips adsorbed on the surface of the magnetic synchronous belt (6), and reuses the treatment liquid. At the same time, after the cleaning work is completed, the metal chips on the surface of the filter screen plate (21) can be discharged in time, which is convenient for subsequent recycling and has diversified functions.
