Description

Technical Field

[0001] This invention relates to the field of milling cutter manufacturing technology, specifically to a convenient tool changer arm for cleaning milling cutters. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth cuts off the excess material of the workpiece in turn. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. After production, milling cutters need to be cleaned by a cleaning device to remove the debris and coolant adhering to their surface.

[0003] After cleaning with cleaning equipment, milling cutters are generally evenly arranged on corresponding cleaning racks. Automatic gripping of cleaned milling cutters is an important part of automated production lines or tool management systems. After cleaning, a thin layer of water film or cleaning agent may remain on the tool surface, which makes the surface slippery, reduces friction, and affects the stability of the mechanical gripper. In addition, water and air can easily accumulate in the milling cutter groove, which may drip during gripping and movement, affecting the environment or subsequent processes. Existing equipment requires automatic or manual boxing after each gripping, which can easily affect the overall efficiency. To address these issues, we propose a convenient tool changer arm for milling cutter cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide a convenient tool changer arm for cleaning milling cutters, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a convenient tool changer arm for cleaning milling cutters, comprising, The transmission frame has a conveyor slide that is movably mounted at its top. One end of the conveyor slide is movably connected to a conveyor shaft with a storage tube at its bottom. The outside of the storage tube is provided with multiple sealed boxes for storing milling cutters. The bottom of the storage tube is provided with a conveyor frame and a positioning frame for calibrating and clamping the milling cutters. The conveyor frame is located at the bottom of the receiving tube. The top of the positioning frame is equipped with multiple adjustable feed shafts, which are connected to the bottom of the conveyor frame. The positioning frame contains multiple positioning shafts for limiting position and a cleaning cone sleeve, which can be fitted onto the top of the milling cutter. The bottom of the conveyor frame is equipped with multiple push plates, and the bottom of the push plates is equipped with a conveying mechanism composed of multiple sets of welding shafts, movable shafts, and telescopic shafts. The top of the telescopic shaft is equipped with a rubber wheel that abuts against the surface of the milling cutter. When the milling cutter needs to be unloaded and boxed, the evenly arranged positions of the milling cutters can be aligned with the positions of the receiving tube. As the conveyor shaft feeds, the calibration shaft can be attached to the outer wall of the milling cutter, and the cleaning cone sleeve can be used to straighten the milling cutter. The top can be locked in the gap of the rubber wheel. Under the control of the internal micro motor, the rubber wheel can drive the milling cutter into the receiving tube by means of friction, which can clamp and store the cleaned milling cutter.

[0006] Preferably, the welding shaft has a hinge groove inside, and a hinge ball is movably engaged in the hinge groove. The movable shaft is U-shaped and has a toothed disc inside. The movable shaft is movably disposed at the bottom end of the hinge groove. The telescopic shaft is connected to the top end of the movable shaft. A reset rod is provided between the telescopic shaft and the hinge ball. Through the coordinated action of the conveying shaft, the push plate, and the conveying mechanism composed of the welding shaft, the movable shaft, the telescopic shaft, and the rubber wheel, combined with the straightening mechanism formed by the positioning shaft, the calibration shaft, and the cleaning cone sleeve, the milling cutter can be automatically straightened during the conveying process. The friction of the rubber wheel is used to efficiently and continuously feed the milling cutter into the storage tube and the sealing box, significantly improving the storage efficiency of the cleaned milling cutter.

[0007] Preferably, the positioning frame has a transmission end block inside, and one end of the transmission end block has a toothed plate connected to a push plate. The toothed plate can fit against the toothed plate to control the axial retraction position of the movable shaft, eliminating the limiting effect of the milling cutter on one side. By using the transmission end block to drive the toothed plate to mesh with the toothed disc inside the movable shaft, the axial retraction of the movable shaft can be precisely controlled.

[0008] Preferably, the positioning frame has multiple docking rods installed inside, and a slide rod is installed at the bottom of the docking rod. The positioning shaft is inclinedly set at the bottom of the slide rod. Multiple reset plugs are provided inside the positioning shaft, and one end of the reset plug is connected to a calibration shaft. The clamping surface of the calibration shaft is provided with a straight groove, and a sponge pad is provided inside the straight groove, which effectively reduces the impact of residual liquid on subsequent transmission, keeps the calibration components dry, prevents slippage, and improves the cleanliness of the tool.

[0009] Preferably, a pair of reset pressure rods are connected to the outside of the cleaning cone sleeve. The reset pressure rods are connected to the top of the calibration shaft. The cleaning cone sleeve and multiple sets of calibration shafts form a straightening mechanism, which enables the milling cutter to be inserted along the cleaning cone sleeve. Combined with the straightening mechanism formed by the positioning shaft, calibration shaft and cleaning cone sleeve, the milling cutter can be automatically straightened during the conveying process.

[0010] Preferably, the cleaning cone sleeve is made of elastic material, and the cleaning cone sleeve has multiple arrayed sponge pads inside to absorb excess cutting fluid remaining on the surface of the milling cutter.

[0011] Preferably, the top of the inner wall of the receiving tube is provided with a connecting plate, the bottom of the connecting plate is fitted with a conveying ring groove, the inside of the conveying ring groove is fitted with a transmission plate, one end of the transmission plate is provided with a set of reset rods, and one end of the reset rods is connected to an adsorption shaft concentrically arranged with the transmission plate. The adsorption shaft can be connected to an external pneumatic device. The adsorption shaft is provided with a contact sensor. When the movable shaft retracts and releases the holding force on one side, the adsorption shaft moves with the milling cutter and triggers the contact sensor, that is, it comes into contact with the rectangular frame. At this time, the adsorption force is automatically released, and the milling cutter slides into the receiving rack. This closed-loop control ensures the continuity and accuracy of the milling cutter from conveying, positioning to releasing and boxing.

[0012] Preferably, the storage tube has multiple rectangular slots on its sidewall, with snap-fit ​​plates at both ends of the rectangular slots. The sealing box is located between the snap-fit ​​plates, and a storage rack is inserted inside the rectangular slots. The storage rack consists of a set of symmetrically arranged bent plates, with multiple compression shafts inside the bent plates. Rectangular frames are provided at the outer ends of the compression shafts at both ends. The rectangular frames are used to control the spacing between the compression shafts. The top of the rectangular frames can abut against the contact sensor. An adsorption plate is snapped at the bottom of the storage rack to absorb excess cleaning fluid. The pluggable design of the storage rack and the control of the compression shaft spacing by the rectangular frames also ensure the compactness and flexibility of the loading.

[0013] Preferably, the outer end of the sealed box is provided with a pair of air extraction holes, which are used to generate negative pressure externally to transport the milling cutter into the sealed box for disassembly and packing, forcefully extracting excess moisture from the box, ensuring that the milling cutter is sealed and stored in a dry environment. The inside of the storage tube absorbs residual moisture by setting an adsorption plate at the bottom of the storage rack. Combined with the ventilation structure formed by the rectangular groove and the snap-fit ​​plate and the air extraction effect of the adsorption shaft, the overall dryness of the environment inside the storage tube is maintained.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention drives the toothed plate to mesh with the toothed disc inside the movable shaft through the transmission end block, which can precisely control the inward contraction of the movable shaft. It can actively cancel the clamping force on the milling cutter on one side at a specific position, and use the remaining clamping force or external force to push the milling cutter to one side to enter the collection rack. It can support batch unloading and boxing of milling cutters, significantly reduce the reciprocating motion time, and improve the overall work efficiency. 2. This invention, through the synergistic action of the conveying shaft, the pushing plate, and the conveying mechanism composed of the welding shaft, the movable shaft, the telescopic shaft, and the rubber wheel, combined with the straightening mechanism formed by the positioning shaft, the calibration shaft, and the cleaning cone sleeve, can automatically straighten the milling cutter during the conveying process and efficiently and continuously feed the milling cutter into the storage tube and the sealing box using the friction of the rubber wheel, significantly improving the storage efficiency of the cleaned milling cutter. 3. This invention provides a sponge pad layer in the straight groove of the calibration shaft clamping surface, a reset plug on the inner side of the positioning shaft, and multiple layers of sponge pads inside the cleaning tapered sleeve. This allows the invention to actively absorb residual cleaning agent and debris on the surface of the milling cutter while clamping the straightening milling cutter. Furthermore, when the cleaning tapered sleeve is pressed against the bottom of the milling cutter, some of the absorbed liquid can be squeezed out for reuse or discharged, effectively reducing the impact of residual liquid on subsequent transmission, keeping the calibration components dry, preventing slippage, and improving the cleanliness of the cutting tool. 4. This invention features a sealed box with an extraction hole, which can be connected to an external negative pressure device. This assists in drawing the milling cutter into the box for positioning and also powerfully extracts excess moisture from the box, ensuring that the milling cutter is stored in a dry and sealed environment. Inside the storage tube, an adsorption plate at the bottom of the storage rack absorbs residual moisture. Combined with the ventilation structure formed by the rectangular groove and the snap-fit ​​plate, and the extraction effect of the adsorption shaft, the overall dryness of the internal environment of the storage tube is maintained, effectively preventing moisture condensation and ensuring the long-term storage quality of the milling cutter.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-9 This invention provides a technical solution: a convenient tool changer arm for cleaning milling cutters, comprising, The transmission frame 1 has a conveyor slide plate 11 that is movably attached to its top. One end of the conveyor slide plate 11 is movably attached to a conveyor shaft 12 with a storage tube 2 connected to its bottom. The outside of the storage tube 2 is provided with multiple sealed boxes 22 for storing milling cutters. The bottom of the storage tube 2 is provided with a conveyor frame 4 and a positioning frame 3 for calibrating and clamping the milling cutters. The conveyor frame 4 is located at the bottom of the receiving tube 2. The top of the positioning frame 3 is equipped with multiple adjustable feed shafts 31, which are connected to the bottom of the conveyor frame 4. The positioning frame 3 is equipped with multiple positioning shafts 33 for limiting and cleaning cone sleeves 35, which can be fitted onto the top of the milling cutter. The bottom of the conveyor frame 4 is equipped with multiple push plates 41. The bottom of the push plates 41 is equipped with a conveying mechanism composed of multiple sets of welding shafts 42, movable shafts 44 and telescopic shafts 45. The top of the telescopic shaft 45 is equipped with a rubber wheel 451 that abuts against the surface of the milling cutter. When the milling cutter needs to be unloaded and boxed, the evenly arranged positions of the milling cutters can be aligned with the positions of the receiving tube 2. As the conveyor shaft 12 feeds, the calibration shaft 331 can be attached to the outer wall of the milling cutter. The cleaning cone sleeve 35 is used to straighten the milling cutter. The top can be locked in the gap of the rubber wheel 451. Under the control of the internal micro motor, the rubber wheel 451 can drive the milling cutter into the receiving tube 2 by friction, which can clamp and store the cleaned milling cutter.

[0018] like Figure 8 and Figure 9As shown, in order to drive the milling cutter feed and storage, the welding shaft 42 is provided with a hinge groove, and a hinge ball 43 is movably locked in the hinge groove. The movable shaft 44 is U-shaped and has a gear plate locked inside. The movable shaft 44 is movably set at the bottom end of the hinge groove. The telescopic shaft 45 is connected to the top end of the movable shaft 44. A reset rod is provided between the telescopic shaft 45 and the hinge ball 43, which can make the rubber wheel 451 fit against the surface of the milling cutter. As the rubber wheel 451 moves in a circle, it moves quickly into the storage tube 2.

[0019] like Figure 5 As shown, the positioning frame 3 has a transmission end block 5 inside, and one end of the transmission end block 5 has a toothed plate 51 connected to the push plate. The toothed plate 51 can fit against the toothed plate and is used to control the inward retraction position of the movable shaft 44, eliminating the limiting effect on the milling cutter on one side. This allows the toothed plate 51 to fit against the toothed plate, which can drive the movable shaft 44 to retract inward, eliminate the holding force on one side of the milling cutter, and push the milling cutter to one side. This provides a thrust for the milling cutter to be inserted into the storage frame 26 on one side, making it easier to store multiple milling cutters at once and reducing the time required for reciprocating motion, thereby improving overall efficiency.

[0020] like Figure 3 and Figure 4 As shown, to ensure the stability of the milling cutter feed, multiple connecting rods 32 are installed inside the positioning frame 3. A sliding rod is installed at the bottom of the connecting rod 32. The positioning shaft 33 is inclined at the bottom of the sliding rod. Multiple reset pins are provided inside the positioning shaft 33, and one end of the reset pin is connected to the calibration shaft 331. The clamping surface of the calibration shaft 331 is provided with a straight groove, and a sponge pad is provided inside the straight groove. As the outer wall of the milling cutter can be squeezed against the sponge pad, the small amount of cleaning agent remaining on the surface of the milling cutter can be quickly absorbed and recovered, reducing the impact on the feed. It can also keep the calibration shaft 331 dry and reduce the occurrence of subsequent slippage accidents.

[0021] like Figure 4 As shown, a pair of reset pressure rods 34 are connected to the outside of the cleaning tapered sleeve 35. The reset pressure rods 34 are connected to the top of the calibration shaft 331. The cleaning tapered sleeve 35 and multiple sets of calibration shafts 331 form a correction mechanism, which allows the milling cutter to be inserted along the cleaning tapered sleeve 35. As the cleaning tapered sleeve 35 is fitted on the top of the milling cutter, and the calibration shaft 331 at the bottom cooperates, the milling cutter can be kept in a vertical state, reducing the tilting and deviation of the milling cutter during transmission.

[0022] like Figure 4As shown, the cleaning tapered sleeve 35 is made of elastic material. The cleaning tapered sleeve 35 has multiple arrayed sponge pads inside, which are used to absorb excess cutting fluid remaining on the surface of the end mill. The sponge pads inside the cleaning tapered sleeve 35 can adhere to the outer wall of the end mill, which not only reduces the residue of cleaning agent, but also reduces the residue of debris and dirt. Subsequently, the top of the cleaning tapered sleeve 35 can abut against the bottom of the end mill. Under the cooperation of the interaction force, the sponge pads inside can be squeezed to squeeze out the absorbed cleaning agent, which can continuously absorb moisture from the end mill.

[0023] like Figure 6 and Figure 7 As shown, to limit the milling cutter, a connecting plate 23 is provided at the top of the inner wall of the receiving tube 2. A conveying ring groove 231 is clamped at the bottom of the connecting plate 23. A transmission plate 24 is movably clamped inside the conveying ring groove 231. A set of reset rods is provided at one end of the transmission plate 24, and one end of the reset rods is connected to an adsorption shaft 25 concentrically arranged with the transmission plate 24. The adsorption shaft 25 can be connected to an external pneumatic device. A contact sensor is provided on the outside of the adsorption shaft 25. The milling cutter can abut against the bottom of the adsorption shaft 25, and the milling cutter is limited under the action of negative pressure. When the positioning frame 3 is fed to a certain position, it can make the toothed plate 51 fit with the toothed disc, drive the movable shaft 44 to retract inward, make the holding force on one side of the milling cutter disappear, and push the milling cutter to one side. When the suction shaft 25 moves with the side of the milling cutter, under the cooperation of the reset shaft, it can make the transmission plate 24 move inside the conveying ring groove 231, and make the suction shaft 25 fit against the top of the rectangular frame 27. At this time, the suction force disappears, and the milling cutter can be stuck inside the collection frame 26 along the compression shaft 261.

[0024] like Figure 7 As shown, in order to reduce the condensation of water vapor inside the receiving tube 2, multiple rectangular grooves are provided on the side wall of the receiving tube 2, and the two ends of the rectangular grooves are provided with snap-fit ​​plates 21. The sealing box 22 is located between the snap-fit ​​plates 21, and a collection rack 26 is inserted inside the rectangular groove. The collection rack 26 is composed of a set of symmetrically arranged bent plates, and multiple compression shafts 261 are provided inside the bent plates. Rectangular frames 27 are provided at the outer ends of the compression shafts 261 at both ends. The rectangular frames 27 are used to control the spacing of the compression shafts 261. The top of the rectangular frames 27 can abut against the contact sensor. An adsorption plate is snapped at the bottom of the collection rack 26 to absorb excess cleaning liquid. The adsorption plate can play a role in absorbing moisture and maintaining the dryness inside the receiving tube 2, and can continuously clamp the milling cutter.

[0025] Preferably, the outer end of the sealed box 22 is provided with a pair of air extraction holes, which are used to generate negative pressure externally to transport the milling cutter into the sealed box 22 for disassembly and assembly. With the help of an external air pressure device connected to the exhaust hole, the milling cutter can be driven to fit against one end of the sealed box 22. At this time, the negative pressure can also reduce the moisture inside and extract it, so that the sealed box 22 is kept sufficiently dry. The operator can replace the sealed box 22 and use the sealing cover to lock and store the milling cutter separately.

[0026] Working principle: First, when the milling cutter needs to be unloaded and boxed, the evenly arranged milling cutter positions can be aligned with the positions of the receiving tube 2. As the conveyor shaft 12 feeds, the calibration shaft 331 can be attached to the outer wall of the milling cutter. With the help of the cleaning cone sleeve 35, the milling cutter is straightened. The top end can be locked in the gap of the rubber wheel 451. Under the control of the internal micro motor, the rubber wheel 451 can drive the milling cutter into the receiving tube 2 by friction. The cleaned milling cutter can be clamped and stored. As the positioning frame 3 feeds, the calibration shaft 331 can be pressed against the top of the milling cutter shank. The cleaning cone sleeve 35 can also be locked on the milling cutter. The cleaned milling cutter is in a vertical feeding state. The top end of the milling cutter is locked between the rubber wheels 451, and the milling cutter can be transported into the receiving tube 2. Then, during the transmission process, the bottom positioning frame 3 moves, allowing the top of the cleaning cone sleeve 35 to abut against the milling cutter, so that its top end is locked at the bottom of the suction shaft 25. Under the action of negative pressure, the milling cutter is limited. As the positioning frame 3 feeds to a certain position, the toothed plate 51 can fit with the toothed disc, which can drive the movable shaft 44 to retract inward, which can make the holding force on one side of the milling cutter disappear, and push the milling cutter to one side. When the suction shaft 25 moves with the side of the milling cutter, under the cooperation of the reset shaft, the transmission plate 24 can move inside the conveying ring groove 231, which can make the suction shaft 25 fit against the top of the rectangular frame 27. At this time, the suction force disappears, and the milling cutter can be locked inside the collection frame 26 along the compression shaft 261, which can temporarily store the milling cutter, can grab multiple milling cutters at a time, and can facilitate the subsequent boxing of the cleaned milling cutters. Finally, after storing multiple milling cutters, an external pneumatic device can be connected to the exhaust port to move the milling cutters to one end of the sealing box 22. At this time, the negative pressure can also reduce the moisture inside and extract it, keeping the sealing box 22 sufficiently dry. The operator can replace the sealing box 22 and use the sealing cover to lock it in place, so that the milling cutters can be stored separately.

[0027] 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.
