Description

Technical Field

[0001] The present invention relates to the technical field of chain tool magazines, and particularly to a modular structure chain tool magazine. Background Art

[0002] A tool magazine system is a device that provides the tool storage and tool change requirements during the automated machining process. The structure of the tool magazine and the tool change method are directly related to the machining range and working efficiency of the machine tool. With the development of social technology, the improvement of the functions of machine tools and the enhancement of efficiency, the requirements for the tool magazine capacity and tool change speed are also continuously increasing.

[0003] In some small factories, the environment is simple and the infrastructure is poor. Therefore, when drilling holes in parts, most of them directly spray water on the drill bit to cool the drill bit. If the drill bit made of high-speed steel is directly inserted into the tool magazine for storage after use, and if the residual water on its surface is not cleaned up, it is easy to rust when the drill bit contacts the air during storage, resulting in frequent replacement of the drill bit and increased production costs.

[0004] For this reason, a modular structure chain tool magazine is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a modular structure chain tool magazine to solve the problem that when drilling holes using the drill bit in the tool magazine in small factories, water is sprayed on the surface of the drill bit to cool the drill bit, and when the drill bit is directly put back into the tool magazine after use, the residual water on the surface of the drill bit is easy to rust, as mentioned in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A modular structure chain tool magazine includes a track, in which a plurality of sleeves are movably installed. A device box is horizontally and fixedly installed on the track. Two oil-absorbing cotton are fixedly installed together between the inner top wall and the inner bottom wall of the device box. An atomizing nozzle is fixedly installed on the inner top wall of the device box, and the atomizing nozzle is located between the two oil-absorbing cotton. An oil box for supplying oil to the atomizing nozzle is fixedly installed on the top wall of the device box, and a recovery mechanism cooperating with the oil box is provided on the device box.

[0008] In some small factories, the environment is simple and the supporting facilities are incomplete. Therefore, when drilling holes using a drill bit, water is usually sprayed on the surface of the drill bit to cool the drill bit, thereby protecting the drill bit. However, if there is residual water on the surface of the drill bit made of high-speed steel and it is directly exposed to the air, it is easy to rust.

[0009] After the drilling is completed, the drill bit is removed from the electric drill by a manipulator and inserted into the sleeve with the tip of the drill bit facing vertically upward. Then, the track is started, and the sleeve is moved within the track to drive the drill bit to move to a specified position. During this process, the sleeve will drive the drill bit through the device box and through two oil-absorbing cotton pads soaked with rust-preventive oil. During the contact between the drill bit and the oil-absorbing cotton pads, the oil on the oil-absorbing cotton pads will be applied to the surface of the drill bit. And when the sleeve passes between the two oil-absorbing cotton pads, since the oil box supplies oil to the atomizing nozzle, the tip of the drill bit will also be covered with oil under the action of the atomizing nozzle.

[0010] When the surface of the drill bit is completed with oil coating, the oil layer covers the surface of the drill bit, isolating the air, thus playing a role in preventing the drill bit from rusting. Then the sleeve continues to drive the drill bit to move and reaches the specified position.

[0011] Preferably, two absorbent cotton pads are fixedly installed on the inner side walls of the front and rear sides of the device box. The two absorbent cotton pads are installed staggered from left to right, and the side walls of the two absorbent cotton pads are closely attached. A drying mechanism for discharging the water on the absorbent cotton pads is provided in the device box.

[0012] The sleeve drives the drill bit to move within the track. During the movement, the sleeve drives the drill bit through the absorbent cotton pads. During the process of gradually passing through the absorbent cotton pads, since the absorbent cotton pads are relatively fluffy, the side wall of the drill bit can fit with the absorbent cotton pads. Since the absorbent cotton pads have a stronger adsorption force for water than the metal drill bit, during this process, the water remaining on the surface of the drill bit will be absorbed by the absorbent cotton pads, thus keeping the surface of the drill bit dry and preventing the drill bit from rusting. And the two absorbent cotton pads are installed staggered. After the first absorbent cotton pad absorbs the larger water on the surface of the drill bit, the first absorbent cotton pad will also remain wet, which will cause the surface of the drill bit to be damp. At this time, the dry second absorbent cotton pad can dry the surface of the drill bit, so that the drill bit remains dry when it disengages from the second absorbent cotton pad. And under the action of the drying mechanism, the water on the absorbent cotton pads can be discharged in time, playing a role in enabling the absorbent cotton pads to continuously absorb water.

[0013] Preferably, the drying mechanism includes a double-headed motor fixedly installed on the top wall of the device box. The first output end of the double-headed motor extends into the device box and is fixedly installed with a fan blade. A plurality of air holes cooperating with the fan blade are opened on the top wall of the device box. A triggering mechanism for triggering the double-headed motor to work is provided on the device box.

[0014] When the sleeve drives the drill bit into the device box for a moment, the triggering mechanism starts to work, so that the dual-head motor operates. The sleeve drives the drill bit to continue moving along the track after passing through the absorbent cotton. And under the action of the triggering mechanism, the dual-head motor drives the fan blades to rotate. During the rotation, the device box absorbs dry air from the outside through the air holes, and the dry air enters the device box and flows outwards under the action of the fan blades. When the gas flowing outwards passes through the absorbent cotton, it will have an impact on the water droplets attached to the absorbent cotton, so that the water absorbed by the absorbent cotton can be discharged, playing a role in ensuring that the absorbent cotton can continuously absorb the water on the surface of the drill bit.

[0015] Preferably, a floating plate is movably arranged in the oil box, a magnet is fixedly installed on the floating plate, the power supply wire of the dual-head motor is wound into a first coil, the first coil is vertically and fixedly installed on the inner top wall of the oil box, an oil delivery pipe communicated with the atomizing nozzle is fixedly installed on the side wall of the oil box, and a first one-way valve is fixedly installed on the oil delivery pipe.

[0016] In the initial state, the floating plate drives the magnet to float on the oil surface of the oil box, and under the action of the first one-way valve, the oil in the oil box cannot flow into the atomizing nozzle.

[0017] When the dual-head motor is powered on, there is an electric current passing through the first coil. At this time, a magnetic field that repels the magnet is generated around the first coil. The magnet has a tendency to move downward under the repulsive force. Therefore, the magnet pushes the floating plate downward. The pushed floating plate squeezes the oil in the oil box. At this time, the pressure in the space below the floating plate in the oil box is relatively large. Therefore, the first one-way valve opens, so that the oil in the oil box can be sprayed through the atomizing nozzle into the space between the two absorbent cotton pads, so that a large amount of oil is suspended in this space. Therefore, when the sleeve drives the drill bit to move to this position, the top of the drill bit will also stick to the oil, improving the coverage rate of the oil on the surface of the drill bit. And the oil suspended in the air will be absorbed by the absorbent cotton when it comes into contact with the absorbent cotton. Therefore, there is always a large amount of oil in the absorbent cotton, playing a role in ensuring that the drill bit can be normally oiled when passing through the absorbent cotton.

[0018] Preferably, the recycling mechanism includes an oil groove opened on the inner bottom wall of the device box. The oil groove is located directly below the absorbent cotton. A collection box is fixedly installed on the bottom wall of the device box. A conduit communicated with the oil groove is fixedly installed on the collection box. A recycling pipe communicated with the oil box is fixedly installed on the bottom wall of the collection box. A second one-way valve is fixedly installed on the recycling pipe. A first spring fixedly connected to the inner bottom wall of the oil box is vertically and fixedly installed on the bottom wall of the floating plate.

[0019] When the dual-head motor is powered on, a magnetic field is generated around the first coil, so that the magnet is pushed downward by the repulsive force in the magnetic field. During the downward movement of the floating plate, the first spring is also compressed and starts to store elastic potential energy.

[0020] Under the action of gravity, the oil on the oil-absorbing cotton will gradually flow downward along the oil-absorbing cotton into the oil tank, and the oil sprayed from the atomizing nozzle can replenish the oil for the oil-absorbing cotton. Therefore, the oil in the oil-absorbing cotton is always dripping downward. The oil dripping into the oil tank flows along the oil pipe into the collection box and accumulates in the collection box.

[0021] When the double-headed motor is powered off, the magnet no longer pushes the floating plate downward. Therefore, the first spring is no longer subjected to a downward extrusion force, so the compressed spring will stretch. The stretched spring pushes the floating plate upward. Under the action of the first one-way valve, the space below the floating plate in the oil box is in a negative pressure state. Therefore, it will absorb oil from the collection box through the recovery pipe to balance the pressure. In this process, the sprayed oil is recycled, playing a role in saving resources.

[0022] Preferably, the trigger mechanism includes a first cavity opened on the device box. A first block made of magnetic material is movably arranged in the first cavity. A second spring is fixedly installed between the first block and the inner wall of the first cavity. A first switch connected in series with the double-headed motor is fixedly installed on the side wall of the first cavity. The wire between the double-headed motor and the first switch is wound into a second coil and vertically fixedly installed on the bottom wall of the first cavity. A second cavity communicating with the first cavity is opened on the device box. A second block is movably arranged in the second cavity.

[0023] In the initial state, under the action of the second spring, the first block extends out of the first cavity, and the second cavity communicating with the first cavity is in a negative pressure state, that is, the second block retracts into the second cavity.

[0024] When the sleeve drives the drill bit into the device box, the side wall of the sleeve contacts and presses the first block. The pressed first block moves along the first cavity. During the movement of the first block, the pressure in the first cavity gradually increases, and at the same time, the pressure in the second cavity communicating with it will also gradually increase. Specifically, the second block gradually extends out of the second cavity, and the second spring is gradually compressed. When the first block completely enters the first cavity, the first switch is pressed, so the double-headed motor is powered on. At this time, a magnetic field with an adsorption effect on the first block is generated around the second coil. Under the action of the magnetic field, the first block always remains in the first cavity. When the sleeve drives the drill bit about to leave the device box, the second block extending out of the second cavity is pressed. At this time, the pressure in the second cavity increases, so the pressure in the first cavity communicating with the second cavity will also increase. When the pressure in the first cavity increases, the first block gradually extends out of the first cavity. At this time, the first switch is no longer pressed, so the switch is disconnected and the double-headed motor is powered off. When the double-headed motor is powered off, the magnetic field around the second coil disappears. At this time, under the action of the second spring, the first block will be pushed out of the first cavity by the second spring, playing a role in preparing for the next operation.

[0025] Preferably, an air pump is fixedly installed on the second output end of the dual-head motor. An air inlet pipe is fixedly installed on the air inlet of the air pump. The air inlet pipe passes through the bottom wall of the device box and is attached to the bottom wall of the water-absorbing cotton.

[0026] During the operation of the dual-head motor, it drives the air pump to operate. Since the air inlet pipe of the air pump is attached to the water-absorbing cotton, during the operation of the air pump, it will absorb air through the water-absorbing cotton. When the air passes through the water-absorbing cotton, it will contact and impact the water droplets on the water-absorbing cotton. Therefore, under the dual action of gravity and the impact force of the air flow, some of the water droplets on the water-absorbing cotton will be quickly discharged through the air pump, which plays a role in improving the drying rate of the water-absorbing cotton.

[0027] Preferably, a warning lamp is fixedly installed on the outer wall of the oil box. A second switch connected in series with the warning lamp is fixedly installed on the inner wall of the oil box. A guide rod is vertically and fixedly installed on the inner bottom wall of the oil box. A floating ball cooperating with the second switch is movably sleeved on the guide rod.

[0028] When a large amount of oil is injected into the oil box, the pressing plate floats on the oil surface. When the oil in the oil box is gradually consumed, the oil surface drops. At this time, the pressing plate moves together with the oil surface. Therefore, when the oil in the oil box is about to be consumed, the floating ball will squeeze the second switch, so that the warning lamp is powered on, reminding the staff to replenish the oil in time, which plays a role in ensuring that the surface of the drill bit can be normally coated with oil.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. The sleeve drives the drill bit to continue moving along the track after passing through the water-absorbing cotton and passes through two oil-absorbing cotton soaked with rust-preventive oil. During the contact between the drill bit and the oil-absorbing cotton, the oil on the oil-absorbing cotton will be coated on the surface of the drill bit. And when the sleeve passes between the two oil-absorbing cotton, since the oil box supplies oil to the atomizing nozzle, under the action of the atomizing nozzle, the top end of the drill bit will also be covered with oil, so that the entire drill bit is covered with an oil layer, isolating the air and preventing the drill bit from rusting.

[0031] 2. During the operation of the dual-head motor, it drives the air pump to operate. Since the air inlet pipe of the air pump is attached to the water-absorbing cotton, during the operation of the air pump, it will absorb air through the water-absorbing cotton. When the air passes through the water-absorbing cotton, it will contact and impact the water droplets on the water-absorbing cotton. Under the dual action of gravity and the impact force of the air flow, some of the water droplets on the water-absorbing cotton will be quickly discharged through the air pump, improving the drying rate of the water-absorbing cotton.

[0032] 3. When a large amount of oil is injected into the oil box, the pressing plate floats on the oil surface. As the oil in the oil box is gradually consumed, the oil level drops. At this time, the pressing plate moves together with the oil level. Therefore, when the oil in the oil box is about to be consumed, the floating ball will squeeze the second switch, thus energizing the warning light and being able to remind the staff to replenish the oil in time.

[0043] Please refer to Figures 1 to 6 , the present invention provides a modular structure chain-type tool magazine, and the technical solution is as follows:

[0044] A modular structure chain-type tool magazine includes a rail 1, in which a plurality of sleeves 2 are movably mounted. Horizontally and fixedly mounted on the rail 1 is a device box 3. Between the inner top wall and the inner bottom wall of the device box 3, two oil-absorbing cotton 4 are fixedly mounted together. Fixedly mounted on the inner top wall of the device box 3 is an atomizing nozzle 5, and the atomizing nozzle 5 is located between the two oil-absorbing cotton 4. Fixedly mounted on the top wall of the device box 3 is an oil box 6 for supplying oil to the atomizing nozzle 5. A recycling mechanism cooperating with the oil box 6 is provided on the device box 3.

[0045] In some small factories, the environment is simple and the supporting facilities are incomplete. Therefore, when using a drill bit to drill holes, water is usually sprayed on the surface of the drill bit to cool the drill bit, so as to protect the drill bit. However, if water remains on the surface of a high-speed steel drill bit and is directly exposed to the air, it is easy to rust.

[0046] After the drilling is completed, the drill bit is removed from the electric drill by a manipulator and inserted into the sleeve 2 with the tip of the drill bit facing vertically upward. Then, the track 1 is started, and the sleeve 2 is moved within the track 1 to drive the drill bit to move to a specified position. During this process, the sleeve 2 will drive the drill bit through the device box 3 and through two oil-absorbing cotton pads 4 soaked with rust-preventive oil. During the contact between the drill bit and the oil-absorbing cotton pad 4, the oil on the oil-absorbing cotton pad 4 will be applied to the surface of the drill bit. And when the sleeve 2 passes between the two oil-absorbing cotton pads 4, since the oil box 6 supplies oil to the atomizing nozzle 5, the tip of the drill bit will also be covered with oil under the action of the atomizing nozzle 5.

[0047] When the surface of the drill bit is completed with oil coating, the oil layer covers the surface of the drill bit, isolating the air, thus playing a role in preventing the drill bit from rusting. Then the sleeve 2 continues to drive the drill bit to move and reaches the specified position.

[0048] As an embodiment of the present invention, referring to Figure 2 , two water-absorbing cotton pads 7 are fixedly installed on the inner side walls of the front and rear sides of the device box 3. The two water-absorbing cotton pads 7 are installed staggered from left to right, and the side walls of the two water-absorbing cotton pads 7 are closely attached. A drying mechanism for discharging the water on the water-absorbing cotton pad 7 is provided in the device box 3.

[0049] The sleeve 2 drives the drill bit to move within the track 1. During the movement, the sleeve 2 drives the drill bit through the water-absorbing cotton pad 7. During the process of gradually passing through the water-absorbing cotton pad 7, since the water-absorbing cotton pad 7 is relatively fluffy, the side wall of the drill bit can be attached to the water-absorbing cotton pad 7. Since the water-absorbing cotton pad 7 has a stronger adsorption force for water than the metal drill bit, during this process, the water remaining on the surface of the drill bit will be absorbed by the water-absorbing cotton pad 7, so that the surface of the drill bit is kept dry, preventing the drill bit from rusting. And the two water-absorbing cotton pads 7 are installed staggered. After the first water-absorbing cotton pad absorbs the larger water on the surface of the drill bit, the first water-absorbing cotton pad will also remain wet, which will cause the surface of the drill bit to be damp. At this time, the dry second water-absorbing cotton pad can dry the surface of the drill bit, so that the drill bit remains dry when it separates from the second water-absorbing cotton pad. And under the action of the drying mechanism, the water on the water-absorbing cotton pad can be discharged in time, playing a role in enabling the water-absorbing cotton pad to continuously absorb water.

[0050] As an embodiment of the present invention, referring to Figure 2 and Figure 3 , the drying mechanism includes a double-headed motor 8 fixedly installed on the top wall of the device box 3. The first output end of the double-headed motor 8 extends into the device box 3 and is fixedly installed with a fan blade 9. A plurality of air holes cooperating with the fan blade 9 are opened on the top wall of the device box 3. A trigger mechanism for triggering the double-headed motor 8 to work is provided on the device box 3.

[0051] When the sleeve 2 drives the drill bit into the device box 3 for an instant, the triggering mechanism starts to work, so that the double-headed motor 8 operates. The sleeve 2 drives the drill bit to continue moving along the track 1 after passing through the water-absorbing cotton 7. And under the action of the triggering mechanism, the double-headed motor 8 drives the fan blade 9 to rotate. During the rotation, the device box 3 absorbs dry air from the outside through the air holes, and the dry air enters the device box 3 and then flows outwards under the action of the fan blade 9. When the outward-flowing gas passes through the water-absorbing cotton 7, it will have an impact on the water droplets attached to the water-absorbing cotton 7, so that the water absorbed by the water-absorbing cotton 7 can be discharged, playing a role in ensuring that the water-absorbing cotton 7 can continuously absorb the water on the surface of the drill bit.

[0052] As an embodiment of the present invention, referring to Figure 5 , a floating plate 10 is movably arranged in the oil box 6, a magnet 11 is fixedly installed on the floating plate 10, the power supply wire of the double-headed motor 8 is wound into a first coil 12, and the first coil 12 is vertically and fixedly installed on the inner top wall of the oil box 6. An oil delivery pipe 13 communicating with the atomizing nozzle 5 is fixedly installed on the side wall of the oil box 6, and a first one-way valve 14 is fixedly installed on the oil delivery pipe 13.

[0053] In the initial state, the floating plate 10 drives the magnet 11 to float on the oil surface of the oil box 6, and under the action of the first one-way valve 14, the oil in the oil box 6 cannot flow into the atomizing nozzle 5.

[0054] When the double-headed motor 8 is powered on, there is an electric current passing through the first coil 12. At this time, a magnetic field that repels the magnet 11 is generated around the first coil 12. The magnet 11 has a tendency to move downward under the repulsive force. Therefore, the magnet 11 pushes the floating plate 10 downward, and the pushed floating plate 10 squeezes the oil in the oil box 6. At this time, the pressure in the space below the floating plate 10 in the oil box 6 is relatively large. Therefore, the first one-way valve 14 opens, so that the oil in the oil box 6 can be sprayed through the atomizing nozzle 5 into the space between the two oil-absorbing cotton 4s, so that a large amount of oil is suspended in this space. Therefore, when the sleeve 2 drives the drill bit to move to this position, the top of the drill bit will also stick to the oil, improving the coverage rate of the oil on the surface of the drill bit. And the oil suspended in the air will be absorbed by the oil-absorbing cotton 4 when it contacts the oil-absorbing cotton 4. Therefore, there is always a large amount of oil in the oil-absorbing cotton 4, playing a role in ensuring that the drill bit can be normally oiled when passing through the oil-absorbing cotton 4.

[0055] As an embodiment of the present invention, referring to Figure 2, the recovery mechanism includes an oil groove opened on the inner bottom wall of the device box 3. The oil groove is located directly below the oil-absorbing cotton 4. A collection box 15 is fixedly installed on the bottom wall of the device box 3. A conduit 16 communicating with the oil groove is fixedly installed on the collection box 15. A recovery pipe 17 communicating with the oil box 6 is fixedly installed on the bottom wall of the collection box 15. A second one-way valve 18 is fixedly installed on the recovery pipe 17. A first spring 19 fixedly connected to the inner bottom wall of the oil box 6 is vertically fixedly installed on the bottom wall of the floating plate 10.

[0056] When the dual-head motor 8 is powered on, a magnetic field is generated around the first coil 12. Thus, the magnet 11 is repelled in the magnetic field and pushes the floating plate 10 downward. During the downward movement of the floating plate 10, the first spring 19 is also compressed and begins to store elastic potential energy.

[0057] Under the action of gravity, the oil on the oil-absorbing cotton 4 will gradually flow downward along the oil-absorbing cotton 4 into the oil groove, and the oil sprayed from the atomizing nozzle 5 can replenish the oil for the oil-absorbing cotton 4. Therefore, the oil in the oil-absorbing cotton 4 is always dripping downward. The oil dripping into the oil groove flows along the oil pipe into the collection box 15 and accumulates in the collection box 15.

[0058] When the dual-head motor 8 is powered off, the magnet 11 no longer pushes the floating plate 10 downward. Therefore, the first spring 19 is no longer subjected to a downward squeezing force. So, the compressed spring will stretch, and the stretching spring pushes the floating plate 10 upward. Under the action of the first one-way valve 14, the space in the oil box 6 below the floating plate 10 is in a negative pressure state. Therefore, it will absorb oil from the collection box 15 through the recovery pipe 17 to balance the pressure. During this process, the sprayed oil is recycled, playing a role in saving resources.

[0059] As an implementation manner of the present invention, referring to Figure 3 , the triggering mechanism includes a first cavity 20 opened on the device box 3. A first block 21 made of a magnetic material is movably arranged in the first cavity 20. A second spring 22 is fixedly installed between the first block 21 and the inner wall of the first cavity 20. A first switch 23 connected in series with the dual-head motor 8 is fixedly installed on the side wall of the first cavity 20. The wire between the dual-head motor 8 and the first switch 23 is wound into a second coil 24 and vertically fixedly installed on the bottom wall of the first cavity 20. A second cavity 25 communicating with the first cavity 20 is opened on the device box 3. A second block 26 is movably arranged in the second cavity 25.

[0060] In the initial state, under the action of the second spring 22, the first block 21 extends out of the first cavity 20, and the second cavity 25 communicating with the first cavity 20 is in a negative pressure state, that is, the second block 26 retracts into the second cavity 25.

[0061] When the sleeve 2 drives the drill bit into the device box 3, the side wall of the sleeve 2 contacts and presses the first block 21. The pressed first block 21 moves along the first cavity 20. During the movement of the first block 21, the pressure in the first cavity 20 gradually increases, and at the same time, the pressure in the second cavity 25 communicated with it will also gradually increase. Specifically, the second block 26 gradually extends out of the second cavity 25, and the second spring 22 is gradually compressed. When the first block 21 completely enters the first cavity 20, the first switch 23 is pressed, so the dual-head motor 8 is powered on. At this time, a magnetic field with an adsorption effect on the first block 21 is generated around the second coil 24. Under the action of the magnetic field, the first block 21 always remains in the first cavity 20. When the sleeve 2 drives the drill bit and is about to leave the device box 3, the second block 26 extending out of the second cavity 25 is pressed, and at this time, the pressure in the second cavity 25 increases. Therefore, the pressure in the first cavity 20 communicated with the second cavity 25 will also increase. After the pressure in the first cavity 20 increases, the first block 21 gradually extends out of the first cavity 20. At this time, the first switch 23 is no longer pressed, so the switch is turned off and the dual-head motor 8 is powered off. After the dual-head motor 8 is powered off, the magnetic field around the second coil 24 disappears. At this time, under the action of the second spring 22, the first block 21 will be pushed out of the first cavity 20 by the second spring 22, playing a role in preparing for the next operation.

[0062] As an embodiment of the present invention, referring to Figure 2 , a suction pump 27 is fixedly installed on the second output end of the dual-head motor 8. An intake pipe 28 is fixedly installed on the intake port of the suction pump 27. The intake pipe 28 passes through the bottom wall of the device box 3 and fits against the bottom wall of the water-absorbing cotton 7.

[0063] During the operation of the dual-head motor 8, it drives the suction pump 27 to operate. Since the intake pipe 28 of the suction pump 27 is in contact with the water-absorbing cotton 7, during the operation of the suction pump 27, it will absorb air through the water-absorbing cotton 7. When the air passes through the water-absorbing cotton 7, it will contact and impact the water droplets on the water-absorbing cotton 7. Therefore, under the dual action of gravity and the impact force of the air flow, some of the water droplets on the water-absorbing cotton 7 will be quickly discharged through the suction pump 27, playing a role in improving the drying rate of the water-absorbing cotton 7.

[0064] As an embodiment of the present invention, referring to Figure 1 and Figure 2 , a warning light 29 is fixedly installed on the outer wall of the oil box 6. A second switch 30 connected in series with the warning light 29 is fixedly installed on the inner wall of the oil box 6. A guide rod 31 is vertically and fixedly installed on the inner bottom wall of the oil box 6. A floating ball 32 cooperating with the second switch 30 is movably sleeved on the guide rod 31.

[0065] When a large amount of oil is injected into the oil box 6, the pressing plate floats on the oil surface. When the oil in the oil box 6 is gradually consumed, the oil surface drops. At this time, the pressing plate moves together with the oil surface. Therefore, when the oil in the oil box 6 is about to be consumed, the floating ball 32 will squeeze the second switch 30, so that the warning light 29 is powered on, reminding the staff to replenish the oil in time, which plays a role in ensuring that the surface of the drill bit can be normally coated with oil.

[0066] Working principle: In some small factories, the environment is simple and the supporting facilities are incomplete. Therefore, when using a drill bit to drill holes, water is usually sprayed on the surface of the drill bit to cool the drill bit, so as to protect the drill bit. However, if there is water remaining on the surface of a high-speed steel drill bit and it is directly exposed to the air, it is easy to rust.

[0067] After the drilling is completed, the drill bit is removed from the electric drill by the manipulator and inserted into the sleeve 2 with the top of the drill bit facing vertically upward. Then the track 1 is started, and the sleeve 2 is driven to move in the track 1 to drive the drill bit to move to the specified position. During this process, the sleeve 2 will drive the drill bit through the device box 3. When the sleeve 2 drives the drill bit into the device box 3 for an instant, the first block 21 is squeezed, and the first block 21 squeezes the second spring 22, so that the double-headed motor 8 operates. Then the sleeve 2 continues to drive the drill bit to move in the track 1. During the movement, the sleeve 2 drives the drill bit through the absorbent cotton 7. During the process of gradually passing through the absorbent cotton 7, because the absorbent cotton 7 is relatively fluffy, the side wall of the drill bit can fit with the absorbent cotton 7. Since the absorbent cotton 7 has a stronger adsorption force for water than the metal drill bit, during this process, the water remaining on the surface of the drill bit will be absorbed by the absorbent cotton 7, so that the surface of the drill bit is in a dry state. And under the action of the trigger mechanism, the double-headed motor 8 drives the fan blade 9 to rotate. During the rotation, the device box 3 absorbs dry air from the outside through the air holes, and the dry air enters the device box 3 and flows outward under the action of the fan blade 9. When the flowing-out gas passes through the absorbent cotton 7, it will have an impact on the water droplets attached to the absorbent cotton 7, so that the water absorbed by the absorbent cotton 7 can be discharged, which plays a role in ensuring that the absorbent cotton 7 can continuously absorb the water on the surface of the drill bit.

[0068] During the operation of the double-headed motor 8, the air pump 27 is driven to operate. Since the air inlet pipe 28 of the air pump 27 is attached to the absorbent cotton 7, during the operation of the air pump 27, air will be absorbed through the absorbent cotton 7. When the air passes through the absorbent cotton 7, it will contact and impact the water droplets on the absorbent cotton 7. Therefore, under the dual action of gravity and the impact force of the air flow, some of the water droplets on the absorbent cotton 7 will be quickly discharged through the air pump 27, which plays a role in improving the drying rate of the absorbent cotton 7.

[0069] The sleeve 2 drives the drill bit to continue moving along the track 1 after passing through the absorbent cotton 7 and passes through two oil-absorbing cotton pads 4 soaked with antirust oil. During the contact between the drill bit and the oil-absorbing cotton pad 4, the oil on the oil-absorbing cotton pad 4 will be applied to the surface of the drill bit. And when the sleeve 2 passes between the two oil-absorbing cotton pads 4, since the oil box 6 supplies oil to the atomizing nozzle 5, the top end of the drill bit will also be covered with oil under the action of the atomizing nozzle 5.

[0070] In the initial state, the floating plate 10 drives the magnet 11 to float on the oil surface of the oil box 6, and under the action of the first one-way valve 14, the oil in the oil box 6 cannot flow into the atomizing nozzle 5.

[0071] When the double-headed motor 8 is powered on, there is an electric current passing through the first coil 12. At this time, a magnetic field that repels the magnet 11 is generated around the first coil 12. After the magnet 11 is subjected to the repulsive force, it has a tendency to move downward. Therefore, the magnet 11 pushes the floating plate 10 downward. The pushed floating plate 10 squeezes the oil in the oil box 6. At this time, the pressure in the space below the floating plate 10 in the oil box 6 is relatively large. Therefore, the first one-way valve 14 opens, so that the oil in the oil box 6 can be sprayed through the atomizing nozzle 5 into the space between the two oil-absorbing cotton pads 4, so that a large amount of oil is suspended in this space. Therefore, when the sleeve 2 drives the drill bit to move to this position, the top end of the drill bit will also stick to the oil, improving the coverage rate of the oil on the surface of the drill bit. And when the oil suspended in the air contacts the oil-absorbing cotton pad 4, it will be absorbed by the oil-absorbing cotton pad 4. Therefore, there is always a large amount of oil in the oil-absorbing cotton pad 4, which plays a role in ensuring that the drill bit can be normally oiled when passing through the oil-absorbing cotton pad 4.

[0072] In the initial state, under the action of the second spring 22, the first block 21 extends out of the first cavity 20, and the second cavity 25 communicating with the first cavity 20 is in a negative pressure state, that is, the second block 26 retracts into the second cavity 25.

[0073] When the sleeve 2 drives the drill bit into the device box 3, the side wall of the sleeve 2 contacts and presses the first block 21. The pressed first block 21 moves along the first cavity 20. During the movement of the first block 21, the pressure in the first cavity 20 gradually increases, and at the same time, the pressure in the second cavity 25 communicated with it will also gradually increase. Specifically, the second block 26 gradually extends out of the second cavity 25, and the second spring 22 is gradually compressed. When the first block 21 completely enters the first cavity 20, the first switch 23 is pressed, so the double-headed motor 8 is powered on. At this time, a magnetic field with an adsorption effect on the first block 21 is generated around the second coil 24. Under the action of the magnetic field, the first block 21 always remains in the first cavity 20. When the sleeve 2 drives the drill bit and is about to leave the device box 3, the second block 26 extending out of the second cavity 25 is pressed. At this time, the pressure in the second cavity 25 increases, so the pressure in the first cavity 20 communicated with the second cavity 25 will also increase. After the pressure in the first cavity 20 increases, the first block 21 gradually extends out of the first cavity 20. At this time, the first switch 23 is no longer pressed, so the switch is disconnected and the double-headed motor 8 is powered off. After the double-headed motor 8 is powered off, the magnetic field around the second coil 24 disappears. At this time, under the action of the second spring 22, the first block 21 will be pushed out of the first cavity 20 by the second spring 22, playing a role in preparing for the next operation.

[0074] When the surface of the drill bit is coated with oil, the oil layer covers the surface of the drill bit, isolating the air, thus playing a role in preventing the drill bit from rusting. Then the sleeve 2 continues to drive the drill bit to move. When it is about to leave the device box 3, the sleeve 2 presses the second block 26, so that the double-headed motor 8 is powered off, playing a role in saving resources.

[0075] When the double-headed motor 8 is powered on, a magnetic field is generated around the first coil 12. Thus, the magnet 11 is repelled by the magnetic field and pushes the floating plate 10 downward. During the downward movement of the floating plate 10, the first spring 19 is also compressed and begins to store elastic potential energy.

[0076] Under the action of gravity, the oil on the oil-absorbing cotton 4 will gradually flow downward along the oil-absorbing cotton 4 into the oil tank, and the oil sprayed from the atomizing nozzle 5 can replenish the oil for the oil-absorbing cotton 4. Therefore, the oil in the oil-absorbing cotton 4 is always dripping downward. The oil dripping into the oil tank flows along the oil pipe into the collection box 15 and accumulates in the collection box 15.

[0077] When the double-headed motor 8 is powered off, the magnet 11 no longer pushes the floating plate 10 downward. Therefore, the first spring 19 is no longer subjected to a downward extrusion force, so the compressed spring will stretch. The stretched spring pushes the floating plate 10 upward. Under the action of the first one-way valve 14, the space in the oil box 6 below the floating plate 10 is in a negative pressure state. Therefore, it will absorb oil from the collection box 15 through the recovery pipe 17 to balance the pressure. During this process, the ejected oil is recycled, playing a role in saving resources.

[0078] When a large amount of oil is injected into the oil box 6, the pressing plate floats on the oil surface. When the oil in the oil box 6 is gradually consumed, the oil surface drops. At this time, the pressing plate moves together with the oil surface. Therefore, when the oil in the oil box 6 is about to be consumed, the floating ball 32 will squeeze the second switch 30, so that the warning lamp 29 is powered on, reminding the staff to replenish the oil in time, playing a role in ensuring that the surface of the drill bit can be normally oiled.
