Description

Technical Field

[0001] This invention relates to the field of cleaning technology, specifically to a small-scale machining tool cleaning device. Background Technology

[0002] Cleaning equipment is a mechanical device that can replace manual labor to clean stains and dirt such as oil, wax, dust, and oxide layers from the surface of workpieces. Currently, the cleaning equipment available on the market includes ultrasonic cleaning, high-pressure spray cleaning, laser cleaning, steam cleaning, dry ice cleaning, and composite cleaning equipment. In industrial production, with the increasing demand for surface cleanliness of product parts, ultrasonic precision cleaning is gaining more and more attention and recognition.

[0003] Currently, after tapping small workpieces with tapping drill bits, the tapping drill bits need to be cleaned and maintained. Before ultrasonic cleaning, a certain amount of clean water needs to be added. However, the water addition process is usually done manually, which can lead to large errors in the amount of water. Too much water will waste resources, while too little water will affect the cleaning effect of the tapping drill bits. Summary of the Invention

[0004] The purpose of this invention is to provide a small-scale machining tool cleaning device. On the one hand, it can automatically prepare a certain amount of water for the next tapping drill bit, reducing the operation of workers. On the other hand, by adopting this quantitative water addition method, the amount of water used for each cleaning can be controlled to save water resources, avoid the abuse of water resources, and avoid insufficient water affecting the cleaning effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a small machining tool cleaning device, comprising a water replenishment tank and a collection tank located below the water replenishment tank, and further comprising: a cleaning mechanism, including a cleaning chamber located inside the water replenishment tank and having an independent cavity inside, a mounting base provided above the cleaning chamber, a motor provided above the mounting base, a hydraulic rod connected to the mounting base provided below the motor, an outer shaft extending into the internal cavity of the cleaning chamber installed at the output end of the motor, an inner shaft sliding inside the outer shaft and extending to the outside at one end; a fan-shaped first water sealing plate and a second water sealing plate slide within the internal cavity of the cleaning chamber, when the inner shaft moves to a certain position, it is closed and connected with the first water sealing plate, and at this time the outer shaft contacts and presses against the first water sealing plate, the first water sealing plate being driven by the outer shaft... The cleaning chamber is connected to the water replenishment tank. One end of the first sealing plate is magnetically attracted and has a magnetic rod passing through it. One end of the magnetic rod is connected to a guide rod, which is connected to the second sealing plate. The magnetic rod can pass through or separate from the second sealing plate after being driven by the first sealing plate, so that the cleaning chamber is closed or connected to the collection tank. A cleaning block adapted to the tapping drill bit is provided at the bottom of the cleaning chamber. The adding mechanism includes a gear that follows the rotation of the outer shaft and moves relative to the outer shaft. One side of the gear is provided with a gear rod driven by a partially meshing tooth. The gear rod passes through the mounting base, and a piston rod is integrally provided at one end of the gear rod. A piston cylinder is sleeved at one end of the piston rod, and a storage pipe communicating with the cleaning chamber is provided at one end of the piston cylinder.

[0006] Optionally, the mounting base is fixedly installed above the cleaning chamber, the hydraulic rod is installed above the mounting base, and a base for mounting the motor is provided above the hydraulic rod.

[0007] Optionally, the outer shaft has an outer groove that slides relative to the gear on its outer side, and the inner shaft has an inner groove that slides relative to the outer shaft on its outer side.

[0008] Optionally, the internal cavity of the cleaning chamber is provided with an adaptation groove for the movement of the first water sealing plate, the second water sealing plate, and the magnetic rod. One end of the magnetic rod is provided with a water sealing ball to control the communication between the internal cavity of the cleaning chamber and the water replenishment tank. The bottom of the second water sealing plate is provided with a water sealing block to control the communication between the internal cavity of the cleaning chamber and the collection tank.

[0009] Optionally, a magnetic block is provided on the bottom inner wall of the internal cavity of the cleaning chamber, and the magnetic block is magnetically connected to the second water sealing plate when it is moved to a certain position.

[0010] Optionally, a fixing sleeve is fixedly provided on one side of the mounting base and sleeved on the outside of the gear rack. The fixing sleeve has a receiving groove to accommodate the rotation of a part of the gear.

[0011] Optionally, the meshing teeth on the outer edge of the gear are distributed only on a portion of the outer edge of the gear.

[0012] Optionally, a piston is installed at one end of the piston rod to push the gas inside the piston cylinder to move, and a one-way gas valve is provided at one end of the piston cylinder.

[0013] Optionally, the storage tube is provided with a pusher plate inside.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, water stored above the first water sealing plate flows to the area below the first water sealing plate. On the one hand, the water washes the tapping drill bit, achieving a secondary cleaning effect. On the other hand, it prepares the next tapping drill bit for use, reducing the number of operators and achieving a high degree of automation. At the same time, this quantitative water addition method can control the amount of water used for each cleaning, saving water resources, avoiding the abuse of water resources, and preventing insufficient water from affecting the cleaning effect.

[0016] 2. In this invention, after the magnetic rod moves to a certain position, the second water-sealing plate drives the water-sealing block to cancel the closed state between the internal cavity of the cleaning chamber and the collection tank. Therefore, the water used to clean the tapping drill bit will flow to the collection tank through the connection and be collected for easy handling by the staff. Then, because the second water-sealing plate loses its magnetic support, and through the magnetic attraction between the second water-sealing plate and the magnetic block, the second water-sealing plate will drive the water-sealing block to fall. At this time, the water used to clean the tapping drill bit has completely flowed into the interior of the collection tank. After the water-sealing block falls, it closes the connection between the internal cavity of the cleaning chamber and the collection tank again. Then, the water stored above the first water-sealing plate flows to the bottom of the first water-sealing plate to supply the next tapping drill bit for cleaning. The automatic alternating water filling method can avoid the reuse of the cleaned water, which would affect the cleaning effect of the tapping drill bit. At the same time, it saves the staff the workload of changing and adding water, and improves the cleaning efficiency of the tapping drill bit.

[0017] 3. The present invention has a piston installed at one end of the piston rod to push the gas inside the piston cylinder to move. Therefore, after the piston rod moves, it can force the cleaning agent inside the storage tube to be sprayed into the internal cavity of the cleaning chamber to assist in the cleaning of the tapping drill bit. Thus, during the process of the outer shaft driving the tapping drill bit to rotate forward through the inner shaft and wiping it through the cleaning block, a certain amount of cleaning agent can be automatically added, saving manual addition operation, controlling the dosage, and avoiding the abuse of cleaning agent.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] This invention provides a small machining tool cleaning device, including a water replenishment tank 1 and a collection tank 4 located below the water replenishment tank 1, and further including: a cleaning mechanism 2, including a cleaning chamber 23 located inside the water replenishment tank 1 and having an independent cavity inside, a mounting base 22 provided above the cleaning chamber 23, a motor 21 provided above the mounting base 22, a hydraulic rod 24 connected to the mounting base 22 provided below the motor 21, an outer shaft 25 extending into the cavity inside the cleaning chamber 23 installed at the output end of the motor 21, an inner shaft 26 that slides inside the outer shaft 25 and extends to the outside at one end; a fan-shaped first water sealing plate 27 and a second water sealing plate 29 slide inside the cavity inside the cleaning chamber 23. When the inner shaft 26 moves to a certain position, it is closed and connected with the first water sealing plate 27. At this time, the outer shaft 25 contacts and squeezes the first water sealing plate 27. After the first water sealing plate 27 is driven by the outer shaft 25, it causes the internal cavity of the cleaning chamber 23 to communicate with the water replenishment tank 1. One end of the first water sealing plate 27 is magnetically attracted and has a magnetic rod 214 passing through it. One end of the magnetic rod 214 is connected to a guide rod 212. The guide rod 212 is connected to the second water sealing plate 29. After the magnetic rod 214 is driven by the first water sealing plate 27, it can pass through or separate from the second water sealing plate 29, so that the internal cavity of the cleaning chamber 23 is closed or connected with the collection tank 4. A cleaning block 28 adapted to the drill bit of the tapping drill bit is provided at the bottom of the internal cavity of the cleaning chamber 23.

[0029] See Figures 1 to 6 As shown, during the cleaning of the tapping drill bit, the hydraulic rod 24 is activated, which raises the motor 21, thereby raising the outer shaft 25. The outer shaft 25 then drives the inner shaft 26 to extend out of the cleaning chamber 23, allowing the tapping drill bit to be mounted on it. Next, the hydraulic rod 24 is activated again, causing the motor 21 to move downwards, allowing the inner shaft 26 to drive the tapping drill bit into the cleaning chamber 23. After the tapping drill bit's rotating head contacts the cleaning block 28, the hydraulic rod 24 stops working. Then, the motor 21 is activated, and its output drives the outer shaft 25 to rotate. The outer shaft 25 then drives the inner shaft 26 to rotate, which in turn drives the tapping drill bit to rotate. Due to the tapping... The drill bit contacts the cleaning block 28. Because the cleaning teeth on the cleaning block 28 are adapted to the drill bit, the cleaning teeth on the cleaning block 28 will rotate relative to the drill bit when the tapping drill bit rotates. Since the cleaning block 28 is fixedly installed on the internal cavity of the cleaning chamber 23, the tapping drill bit will move down along the cleaning block 28 while rotating. Thus, the drill bit can be wiped by the cleaning block 28. Combined with ultrasonic cleaning, the cleaning effect of the drill bit can be further guaranteed, avoiding the difficulty of cleaning thoroughly by a single cleaning method. In addition, the forward and reverse rotation of the motor 21 can be controlled to control the way the cleaning block 28 wipes the drill bit, and the adaptation connection between the cleaning block 28 and the drill bit can be canceled.

[0030] Mounting base 22 is fixedly installed above cleaning chamber 23. Hydraulic rod 24 is installed above mounting base 22. A base for mounting motor 21 is provided above hydraulic rod 24. The outer side of outer shaft 25 is provided with an outer groove that slides relative to gear 33. The outer side of inner shaft 26 is provided with an inner groove that slides relative to outer shaft 25. The internal cavity of cleaning chamber 23 is provided with adaptation grooves for the movement of first sealing plate 27, second sealing plate 29, and magnetic rod 214. One end of magnetic rod 214 is provided with a control cleaning groove. The inner cavity of the washing chamber 23 is connected to the water replenishment tank 1 by a water sealing ball 213. The bottom of the second water sealing plate 29 is provided with a water sealing block 211 that controls the connection between the inner cavity of the washing chamber 23 and the collection tank 4. The bottom inner wall of the inner cavity of the washing chamber 23 is provided with a magnetic block 210. The magnetic block 210 is magnetically attracted to the second water sealing plate 29 when it is moved to a certain position. A fixed sleeve 31 is fixedly provided on one side of the mounting base 22 and sleeved on the outside of the gear 32. The fixed sleeve 31 has a receiving groove to accommodate a part of the rotation of the gear 33.

[0031] See Figure 6As shown, during the process of the outer shaft 25 driving the inner shaft 26 to move downwards within the internal cavity of the cleaning chamber 23, after the inner shaft 26 passes through the first water sealing plate 27, the outer shaft 25 contacts the first water sealing plate 27. At this time, the downward movement of the outer shaft 25 will drive the first water sealing plate 27 to move downwards. Simultaneously, the downward movement of the first water sealing plate 27 will drive the magnetic rod 214 to move. The magnetic rod 214 will drive the water sealing ball 213 to move. After the water sealing ball 213 moves, the internal cavity of the cleaning chamber 23 will connect with the water replenishment tank 1, and the water inside the water replenishment tank 1 will enter the cleaning chamber 23. The cleaning chamber 23 contains the internal cavity and is located above the first water sealing plate 27. At this time, the second water sealing plate 29 drives the water sealing block 211 to seal the connection between the internal cavity of the cleaning chamber 23 and the collection tank 4. After the tapping drill bit is ultrasonically cleaned and processed with the cleaning block 28, the hydraulic rod 24 starts to drive the motor 21 to move upward. Since the outer shaft 25 is in contact with and magnetically connected to the first water sealing plate 27, during the process of the outer shaft 25 driving the tapping drill bit out of the internal cavity of the cleaning chamber 23 through the inner shaft 26, The first water-sealing plate 27 moves with the outer shaft 25, causing the magnetic rod 214 to move upward. The magnetic rod 214 then causes the guide rod 212 to move upward. Simultaneously, since the magnetic rod 214 is magnetically connected to the second water-sealing plate 29, the upward movement of the magnetic rod 214 causes the second water-sealing plate 29 to move. At this point, the second water-sealing plate 29 releases its magnetic attraction to the magnetic block 210. After the magnetic rod 214 reaches a certain position, the second water-sealing plate 29 causes the water-sealing block 211 to disengage from the internal cavity of the cleaning chamber 23. The collection tank 4 is in a closed state, so the water used to clean the tapping drill bit will flow to the collection tank 4 through the connection for collection, making it convenient for staff to handle. In addition, it should be noted that the magnetic attraction between the second water sealing plate 29 and the magnetic rod 214 is greater than the magnetic attraction between the second water sealing plate 29 and the magnetic block 210. Therefore, when the magnetic rod 214 moves the second water sealing plate 29 by magnetic attraction, it can drive the second water sealing plate 29 and the magnetic block 210 to cancel the magnetic attraction, ensuring that the magnetic rod 214 can move the second water sealing plate 29 by magnetic attraction.

[0032] After the outer shaft 25 drives the first water sealing plate 27 to move upward to another position, the water sealing ball 213 will reset and seal the internal cavity of the cleaning chamber 23 and the water replenishment pool 1 again. Then, after the outer shaft 25 continues to move upward, it will no longer drive the first water sealing plate 27 to move. After the outer shaft 25 drives the inner shaft 26 and the tapping drill bit to move upward and pass through the first water sealing plate 27, the water stored above the first water sealing plate 27 will flow to the bottom of the first water sealing plate 27. On the one hand, the water will rinse the tapping drill bit, achieving a secondary cleaning effect. On the other hand, it will prepare for the next tapping drill bit, reducing the operation of the staff and achieving high automation. At the same time, by adopting this quantitative water addition method, the amount of water used for each cleaning can be controlled, saving water resources, avoiding the abuse of water resources, and avoiding insufficient water affecting the cleaning effect.

[0033] See Figure 7As shown, after the magnetic rod 214 moves the sealing ball 213 upward to close the internal cavity of the cleaning chamber 23 and connect it with the water replenishment tank 1, and before the water stored above the first sealing plate 27 flows downward to the bottom of the first sealing plate 27, the magnetic rod 214 will no longer be magnetically connected to the second sealing plate 29. At this time, the guide rod 212 is connected to the second sealing plate 29 through. Since the second sealing plate 29 loses its magnetic support, and through the magnetic attraction between the second sealing plate 29 and the magnetic block 210, the second sealing plate 29 will drive the sealing block 211 downward. As the water for cleaning the tapping drill bit falls, it has completely flowed into the collection tank 4. After the sealing block 211 falls, it seals the connection between the internal cavity of the cleaning chamber 23 and the collection tank 4 again. Then, the water stored above the first sealing plate 27 flows down to supply the next tapping drill bit for cleaning. The automatic alternating water filling method can avoid the reuse of the water after cleaning, which would affect the cleaning effect of the tapping drill bit. At the same time, it saves the workload of changing and adding water for the staff and improves the cleaning efficiency of the tapping drill bit.

[0034] The addition mechanism 3 includes a gear 33 that rotates with and moves relative to the outer shaft 25. A gear 33 is provided on one side of the gear 33 and is driven by a gear rod 32 through a partial meshing tooth. The gear rod 32 passes through the mounting base 22, and a piston rod 36 is integrally provided at one end of the gear rod 32. A piston cylinder 35 is sleeved at one end of the piston rod 36. A storage pipe 34 communicating with the internal cavity of the cleaning chamber 23 is provided at one end of the piston cylinder 35. The meshing teeth on the outer edge of the gear 33 are only distributed on a part of the outer edge of the gear 33. A piston that pushes the gas inside the piston cylinder 35 is installed at one end of the piston rod 36. A gas one-way valve is provided at one end of the piston cylinder 35. A push plate is provided inside the storage pipe 34.

[0035] During the process of the outer shaft 25 driving the tapping drill bit to rotate via the inner shaft 26, the outer shaft 25 drives the gear 33 to rotate. The gear 33 drives the gear rod 32 to move through meshing teeth. The gear rod 32 drives the piston rod 36 to move. Since a piston is installed at one end of the piston rod 36 to push the gas inside the piston cylinder 35, the movement of the piston rod 36 can force the cleaning agent inside the storage pipe 34 to be sprayed into the internal cavity of the cleaning chamber 23, assisting in the cleaning of the tapping drill bit. Thus, during the process of the outer shaft 25 driving the tapping drill bit to rotate forward via the inner shaft 26 and wiping it with the cleaning block 28, a certain amount of cleaning agent can be automatically added, saving manual addition operations while controlling the dosage and avoiding the abuse of cleaning agent. In addition, during the process of the outer shaft 25 driving the tapping drill bit to rotate in the reverse direction via the inner shaft 26, a certain amount of cleaning agent can be automatically added. During the process of disconnecting the drill bit from the cleaning block 28, the gear 33 drives the gear rod 32 to move in the opposite direction, and the gear rod 32 drives the piston rod 36 to move in the opposite direction. Since a gas check valve is provided at one end of the piston cylinder 35, the cleaning agent inside the storage tube 34 will not flow in the opposite direction after the piston rod 36 moves in the opposite direction. In addition, the meshing teeth on the outer edge of the gear 33 are only distributed on a part of the outer edge of the gear 33. During the process of the outer shaft 25 driving the gear 33 to rotate, the gear 33 can only drive the gear rod 32 to move a distance, and then the gear 33 will not be able to drive the gear rod 32 to move. This avoids the gear rod 32 driving the piston rod 36 to move continuously during the process of the gear 33, which would cause the cleaning agent inside the storage tube 34 to be continuously added to the internal cavity of the cleaning chamber 23, resulting in the abuse of cleaning agent.

[0036] In addition, since the tapping drill bit is small in size, the amount of water used for cleaning is also small. Therefore, the weight of the water stored on the first water sealing plate 27 will not affect the magnetic attraction between the first water sealing plate 27 and the outer shaft 25, thus preventing the water from being too heavy and pressing the first water sealing plate 27 to move, causing the first water sealing plate 27 to drive the magnetic rod 214 to move, thereby failing to change the connection state between the water replenishment pool 1 and the internal cavity of the cleaning chamber 23.

[0037] Working principle: Start the hydraulic rod 24, which raises the motor 21, which in turn raises the outer shaft 25. The outer shaft 25 then drives the inner shaft 26 to extend out of the cleaning chamber 23, allowing the tapping drill bit to be installed on the inner shaft 26.

[0038] In the first cleaning method, the hydraulic rod 24 is activated, driving the motor 21 to move downwards. This causes the inner shaft 26 to drive the tapping drill bit into the internal cavity of the cleaning chamber 23. After the tapping drill bit's rotating head contacts the cleaning block 28, the hydraulic rod 24 stops working. Then, the motor 21 is activated, and its output end drives the outer shaft 25 to rotate. The outer shaft 25 drives the inner shaft 26 to rotate, and the inner shaft 26 drives the tapping drill bit to rotate. Since the tapping drill bit contacts the cleaning block 28, and because the cleaning teeth on the cleaning block 28 are compatible with the drill bit, the cleaning teeth on the cleaning block 28 will rotate relative to the drill bit when the tapping drill bit rotates. Because the cleaning block 28 is fixedly installed on the internal cavity of the cleaning chamber 23, the tapping drill bit will move downwards along the cleaning block 28 while rotating, thus allowing the drill bit to be wiped through the cleaning block 28.

[0039] In the second cleaning method, as the outer shaft 25 drives the inner shaft 26 to move downwards within the cleaning chamber 23, the inner shaft 26 passes through the first water-sealing plate 27, and then the outer shaft 25 contacts the first water-sealing plate 27. At this time, the downward movement of the outer shaft 25 will drive the first water-sealing plate 27 to move downwards. Simultaneously, the downward movement of the first water-sealing plate 27 will move the magnetic rod 214, which in turn moves the water-sealing ball 213. After the water-sealing ball 213 moves, the internal cavity of the cleaning chamber 23 connects with the water replenishment tank 1. Water from the water replenishment tank 1 enters the internal cavity of the cleaning chamber 23 and is stored above the first water-sealing plate 27. At this time, the second water-sealing plate 29 drives the water-sealing block 211 to seal the connection between the internal cavity of the cleaning chamber 23 and the collection tank 4. (Tapping drill bit) After ultrasonic cleaning and treatment with the cleaning block 28, the hydraulic rod 24 begins to drive the motor 21 to move upward. Since the outer shaft 25 is in contact with and magnetically connected to the first water-sealing plate 27, as the outer shaft 25 moves the tapping drill bit out of the cleaning chamber 23 via the inner shaft 26, the first water-sealing plate 27 moves along with the outer shaft 25. The first water-sealing plate 27 drives the magnetic rod 214 to move upward, and the magnetic rod 214 drives the guide rod 212 to move upward. Simultaneously, since the magnetic rod 214 is magnetically connected to the second water-sealing plate 29, the upward movement of the magnetic rod 214 drives the second water-sealing plate 29 to move. At this time, the second water-sealing plate 29 releases its magnetic attraction to the magnetic block 210. After the magnetic rod 214 moves to a certain position, the second water-sealing plate 29... The water pan 29 drives the water sealing block 211 to cancel the closed state between the internal cavity of the cleaning chamber 23 and the collection tank 4. Therefore, the water used to clean the tapping drill bit will flow through the connection to the collection tank 4 for collection. After the outer shaft 25 drives the first water sealing pan 27 to move upward to another position, the water sealing ball 213 will reset and close the connection between the internal cavity of the cleaning chamber 23 and the water replenishment tank 1 again. Then, after the outer shaft 25 continues to move upward, it will no longer drive the first water sealing pan 27 to move. After the outer shaft 25 drives the inner shaft 26 and the tapping drill bit to move upward and pass through the first water sealing pan 27, the water stored above the first water sealing pan 27 will flow to the bottom of the first water sealing pan 27. The magnetic rod 214 drives the water sealing ball 213 to move upward and close the connection between the internal cavity of the cleaning chamber 23 and the water replenishment tank 1. After the water replenishment tank 1 is connected, and before the water stored above the first water sealing plate 27 flows to the bottom of the first water sealing plate 27, the magnetic rod 214 will no longer be magnetically connected to the second water sealing plate 29. At this time, the guide rod 212 is connected to the second water sealing plate 29. Since the second water sealing plate 29 loses its magnetic support, and through the magnetic attraction between the second water sealing plate 29 and the magnetic block 210, the second water sealing plate 29 will drive the water sealing block 211 to fall. At this time, the water for cleaning the tapping drill bit has completely flowed into the inside of the collection tank 4. After the water sealing block 211 falls, it will close the connection between the internal cavity of the cleaning chamber 23 and the collection tank 4 again. Then, the water stored above the first water sealing plate 27 flows to the bottom of the first water sealing plate 27 to supply the next tapping drill bit for cleaning.

[0040] During the process of the outer shaft 25 driving the tapping drill bit to rotate through the inner shaft 26, the outer shaft 25 drives the gear 33 to rotate. The gear 33 drives the gear rod 32 to move through the meshing teeth. The gear rod 32 drives the piston rod 36 to move. Since a piston is installed at one end of the piston rod 36 to push the gas inside the piston cylinder 35 to move, the piston rod 36 can force the cleaning agent inside the storage tube 34 to be sprayed into the internal cavity of the cleaning chamber 23 after it moves, thus assisting in the cleaning of the tapping drill bit.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
