TECHNICAL FIELD

[0001] The present application relates to the technical field of tool holder cleaning, and in particular to a tool holder cleaning device and a cleaning method thereof. BACKGROUND

[0002] During use, the taper shank of the tool holder will be mixed and attached with dust, oil stains, metal debris and other impurities in the equipment, and will also be rusted due to moisture in the air. When the taper shank has impurities or rust, directly installing it into the machining equipment will affect the assembly accuracy of the tool holder. Therefore, the tool holder needs to be cleaned before installation.

[0003] The tool holder cleaning devices on the market usually have a tool holder clamping ring for fixing the tool holder.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0020] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a knife handle cleaning device for cleaning the surface of the tapered shank portion 10 of a knife handle 1. Specifically, the tool handle cleaning device includes a tool handle cleaning mechanism, a controller 500, and an operation panel 600. The tool handle cleaning mechanism includes a housing 2, a cleaning head 100, a drive base 200, an opening and closing assembly 300, and a self-aligning assembly 400. The cleaning head 100 is disposed inside the housing 2, and multiple cleaning heads 100 are distributed around the circumference of the tool handle 1 to clean the surface of the tapered shank portion 10 of the tool handle 1. The drive base 200 is used to drive the multiple cleaning heads 100 to revolve around the axis of the tool handle 1 while also driving the cleaning heads 100 to rotate on their own axis. The opening and closing assembly 300 is disposed on the housing 2, and a locking port 331 is formed on the opening and closing assembly 300 for engaging the tool handle 1. The size of the locking port 331 is adjustable. The self-aligning assembly 400 is used to adjust the distance between the multiple cleaning heads 100 and the tool handle 1. The controller 500 is electrically connected to the drive base 200, the opening and closing assembly 300, and the self-aligning assembly 400, respectively. The operation panel 600 is electrically connected to the controller 500. The cleaning head 100 is a brush head, which can be made of wear-resistant nylon composite material. During operation, the operator first inputs the type of the handle 1 to the controller 500 via the control panel 600. Based on the type of handle 1, the controller 500 controls the locking port 331 of the opening and closing assembly 300 to open to the first preset position, allowing the locking port 331 to accommodate the corresponding type of handle 1 while simultaneously locking the flange portion 11 of the handle 1. Then, the conical shank portion 10 of the handle 1 is aligned with the locking port 331 of the opening and closing assembly 300. The controller 500 drives the opening and closing assembly 300 to adjust the size of the locking port 331 until it tightly locks the handle 1 to achieve positioning and prevent displacement during cleaning. Next, the controller 500 controls the self-aligning assembly 400 to fine-tune the distance between the multiple cleaning heads 100 distributed around the handle 1 and the conical shank portion 10, ensuring uniform contact pressure between all cleaning heads 100 and the surface of the conical shank portion 10. Then, the controller drives... The base 200 drives the cleaning head 100 to revolve around the axis of the handle 1 while rotating itself. Through this dual motion, dust, oil, metal shavings, and other debris are thoroughly removed from the surface of the tapered handle 10. After cleaning, the base 200 stops, and the opening / closing assembly 300 and the self-aligning assembly 400 reset. The entire process requires minimal manual intervention. The cleaning head 100's revolution and rotation work together to improve the thoroughness of the cleaning. Furthermore, the self-adaptive locking of the opening / closing assembly 300 and the precise adjustment of the self-aligning assembly 400 adapt to different sizes of handles 1, preventing damage to the surface of the handle 1. This significantly reduces human error and improves cleaning efficiency and quality. This handle cleaning device can perform one-button cleaning of the tapered handle 10 of the handle 1, adapting to different sizes of handles and enabling one device to clean multiple types of handles.

[0021] like Figures 3-5As shown, the opening and closing assembly 300 includes a base 310, a turntable 320, and multiple blades 330. The turntable 320 is ring-shaped and rotatably mounted on the base 310. An opening 311 is formed on the base 310. A support frame 312 is provided on the inner side of the base 310 corresponding to the opening 311. The multiple blades 330 are centrally symmetrically distributed and are attached end to end to form a ring shape. The multiple blades 330 are distributed between the turntable 320 and the support frame 312. When the turntable 320 rotates, it can drive the multiple blades 330 to move synchronously, thereby adjusting the size of the locking opening 331.

[0022] Furthermore, an upper connecting post 332 is fixed to the upper surface of the blade 330, and a lower connecting post 333 is fixed to the lower surface of the blade 330. The upper connecting post 332 and the lower connecting post 333 are coaxially arranged in the vertical direction. A plurality of guide holes 313 are formed on the support frame 312 in a ring-shaped distribution. A guide groove 321 is formed on the side of the turntable 320 facing the blade 330. The upper connecting post 332 is slidably inserted into the guide groove 321, and the lower connecting post 333 is slidably inserted into the guide hole 313. The blade 330 includes adjacent first sliding edges 334 and second sliding edges 335. The first sliding edge 334 of the blade 330 is slidably connected to the second sliding edge 335 of the adjacent blade 330. When the first sliding edge 334 and the second sliding edge 335 slide relative to each other, the blade 330 rotates around the axis of the upper connecting post 332 / lower connecting post 333. When the turntable 320 rotates, the guide groove 321 rotates synchronously with the turntable 320. The guide groove 321 drives the upper connecting post 332 to move, and the upper connecting post 332 drives the blade 330 to move. Since the lower connecting post 333, which is fixed to the blade 330, is inserted into the guide hole 313, the blade 330 needs to move along the direction of the guide hole 313. Since multiple blades 330 are in contact with each other, during the movement of the blade 330, the first sliding edge 334 of the blade 330 and the second sliding edge 335 of the adjacent blade 330 slide relative to each other. Therefore, while the blade 330 moves along the direction of the guide hole 313, it rotates around the axis of the upper connecting post 332 / lower connecting post 333, thereby realizing the adjustment of the size of the locking port 331.

[0023] Both the guide groove 321 and the locking port 331 are regular polygonal structures, and the number of sides of the guide groove 321 is equal to the number of sides of the locking port 331, and also equal to the number of blades 330. (Reference) Figure 6AIn this state, the locking opening 331 is at its maximum opening size, and the upper connecting post 332 is located at the apex of the guide groove 321, which is a regular polygonal structure. When it is necessary to reduce the opening size of the locking opening 331, the drive turntable 320 rotates clockwise, and the guide groove 321 on the turntable 320 rotates synchronously. At this time, the upper connecting post 332, located at the apex, slowly moves towards the center of the edge of the guide groove 321, which is a regular polygonal structure. At the same time, the lower connecting post 333 slides along the guide hole 313 towards the center of the support frame 312, and the first sliding edge 334 of the blade 330 slides relative to the second sliding edge 335 of the adjacent blade 330 until the upper connecting post 332 moves to the center of the edge of the guide groove 321. Figure 6B In this state, the locking opening 331 is at its smallest opening size. If it is necessary to increase the opening size of the locking opening 331 again, the turntable 320 needs to be driven to rotate counterclockwise, and the upper connecting post 332 moves back to the apex of the guide groove 321. Similarly, during the movement of the upper connecting post 332, the lower connecting post 333 slides along the direction of the guide hole 313, and the first sliding edge 334 of the blade 330 slides relative to the second sliding edge 335 of the adjacent blade 330. In this embodiment, both the guide groove 321 and the locking opening 331 are regular hexagonal structures, and there are six blades 330.

[0024] The opening and closing assembly 300 also includes a cover plate 340, which is ring-shaped and fixed to the base 310, and the cover plate 340 is clearance-fitted with the upper surface of the turntable 320. The cover plate 340 is used to limit the turntable 320, preventing the turntable 320 from detaching from the base 310 during rotation, thereby improving the stability of the structure.

[0025] The opening and closing assembly 300 also includes a first motor 350, a first gear 360, and a rack 370. The first gear 360 is fixed to the output shaft of the first motor 350 and meshes with the rack 370. The rack 370 is fixed to the outer circumferential surface of the turntable 320. When the first motor 350 starts, it drives the first gear 360 to rotate, which in turn drives the turntable 320 to rotate via the rack 370.

[0026] like Figures 7-9As shown, the self-aligning assembly 400 includes a base plate 410, a pressure plate 420, a central shaft 430, a geared disc 440, a second motor 450, sliding blocks 470, and bushings 480. A sliding hole 411 is formed on the base plate 410. The pressure plate 420 is fixedly connected to the base plate 410, and a sliding groove 421 is formed on the pressure plate 420, with the axial direction of the groove 421 aligned with that of the sliding hole 411. The central shaft 430 is fixed to the base plate 410. The knife handle 1 is coaxially arranged with the central shaft 430. The geared disc 440 is rotatably mounted between the base plate 410 and the pressure plate 420, and is fixedly connected to the central shaft 430 via a first bearing 441. A second gear 460 is fixedly mounted on the output shaft of the second motor 450, meshing with the geared disc 440. Multiple sliding blocks 470 are fixedly connected to multiple cleaning heads 100 in a one-to-one correspondence. The multiple sliding blocks 470 are slidably connected to the multiple sliding grooves 421 one by one, and the multiple bushings 480 are corresponding to the multiple sliding blocks 470 one by one. The bushings 480 are fixed to the end of the sliding block 470 away from the cleaning head 100, and the bushings 480 are slidably inserted into the sliding hole 411. The gear plate 440 has multiple arc-shaped holes 442 that correspond to the multiple bushings 480 one by one. The bushings 480 pass through the arc-shaped holes 442 and can reciprocate along the direction of the arc-shaped holes 442. The distance from the point on the center line of the arc-shaped hole 442 from one end to the other end to the central axis 430 gradually increases or gradually decreases. When the arc-shaped hole 442 rotates clockwise / counterclockwise with the gear plate 440, it drives the bushings 480 to move closer to / away from the central axis 430 at the same time, and then drives the cleaning head 100 to move closer to / away from the handle 1 through the sliding block 470. During operation, the second motor 450 drives the second gear 460 to rotate, the second gear 460 drives the gear disk 440 to rotate, and at the same time, the arc-shaped hole 442 moves synchronously with the gear disk 440. The arc-shaped hole 442 drives the bushing 480 to slide along the sliding hole 411. Meanwhile, the sliding block 470 moves along the direction of the sliding groove 421, thereby driving the cleaning head 100 to move closer to or away from the handle 1.

[0027] like Figure 9 As shown, the drive base 200 includes a fourth motor 210 and a rotating shaft 220. The fourth motor 210 is fixed to the bushing 480, and the rotating shaft 220 is fixedly connected to the sliding block 470 via a second bearing 230. One end of the rotating shaft 220 is fixedly connected to the cleaning head 100, and the other end of the rotating shaft 220 passes through the bushing 480 and is fixedly connected to the output shaft of the fourth motor 210. After the fourth motor 210 drives the rotating shaft 220 to rotate, it can drive the cleaning head 100 to rotate. In addition, an electric slip ring 431 is fixed below the central shaft 430 to prevent the cable of the fourth motor 210 from getting tangled.

[0028] like Figure 10As shown, the drive base 200 also includes a third motor 240, a third gear 250, and a turntable bearing 260. The outer ring 261 of the turntable bearing 260 is fixedly connected to the base plate 20 of the housing 2, and the inner ring 262 of the turntable bearing 260 is fixedly connected to the base plate 410 of the self-aligning assembly 400. The third gear 250 is fixedly connected to the output shaft of the third motor 240 and meshes with the inner ring 262 of the turntable bearing 260. In this embodiment, the inner peripheral wall of the inner ring 262 of the turntable bearing 260 has a toothed structure. When the third motor 240 drives the third gear 250 to rotate, the third gear 250 drives the inner ring 262 of the bearing 260 to rotate, thereby driving the self-aligning assembly 400 to rotate, so that the cleaning head 100 on the self-aligning assembly 400 revolves around the axis of the handle 1.

[0029] like Figure 11 As shown, the tool handle cleaning device also includes a frame 700, on which the tool handle cleaning mechanism is mounted. In this embodiment, the frame 700 is a movable trolley with wheels 710 mounted underneath, and a handle 720 for the user to hold is provided on the frame 700.

[0030] like Figure 12 As shown, the handle cleaning device also includes a vacuum cleaner 800, which is disposed on the frame 700 and communicates with the inside of the housing 2, and is used to suck up the dust that has been cleaned off the handle 1.

[0031] The tool handle cleaning device also includes an ultrasonic cleaning tank 900, which is mounted on the frame 700 and is used to clean the tool handle 1 after it has been cleaned by the tool handle cleaning mechanism.

[0032] The knife handle cleaning device also includes a drying assembly, which includes a drying tank 910 and a dryer 911 connected to the drying tank 910 via a corrugated pipe. The drying tank 910 is mounted on a frame 700 for placing the cleaned knife handle 1, and the dryer 911 is used to dry the knife handle 1 in the drying tank 910. In this embodiment, the temperature and airflow of the dryer 911 are adjustable.

[0033] The knife handle cleaning device also includes a transfer tank 920, which is used to temporarily place the cleaned knife handle 1. Both the drying tank 910 and the transfer tank 920 are equipped with filter plates 921.

[0034] In this embodiment, a wastewater tank 730 is also provided on one side inside the frame 700. The bottoms of the ultrasonic cleaning tank 900, the transfer tank 920, and the drying tank 910 are all connected to the wastewater tank 730 via pipelines. Furthermore, an electromagnetic valve is installed on the pipeline of the ultrasonic cleaning tank 900. During operation, the electromagnetic valve controls the pipeline to close; after cleaning, the electromagnetic valve controls the pipeline to open, allowing the waste liquid in the ultrasonic cleaning tank 900 to flow from the pipeline into the wastewater tank 730.

[0035] In this embodiment, a partition 740 is also provided on the other side of the rack 700, wherein the dryer 911 and the vacuum cleaner 800 are arranged on the partition 740, the controller 500 is located below the partition 740, and a fan 750 for cooling the controller 500 is also installed on the side wall of the rack 700.

[0036] like Figure 13 As shown, the present invention also provides a cleaning method for a knife handle cleaning device, comprising the following steps: S1: Enter the type of tool holder 1 in the operation panel 600.

[0037] S2: Depending on the type of tool holder 1, the controller 500 controls the locking port 331 of the opening and closing assembly 300 to open to the first preset position, so that the locking port 331 can be inserted into the corresponding type of tool holder 1 while locking the flange portion 11 of the tool holder 1.

[0038] S3: After placing the handle 1 in the locking port 331, activate the cleaning button. The controller 500 controls the locking port 331 of the opening and closing assembly 300 to shrink from the first preset position to the second preset position, thereby fixing the handle 1.

[0039] S4: Depending on the type of tool holder 1, the controller 500 controls the self-aligning assembly 400 to drive the cleaning head 100 to move, so that the cleaning head 100 contacts the surface of the tapered shank portion 10 of the tool holder 1.

[0040] S5: Controller 500 controls the start of drive base 200. Drive base 200 drives multiple cleaning heads 100 to revolve around the axial direction of tool holder 1 while driving the cleaning heads 100 to rotate on their own axis.

[0041] S6: After cleaning, the drive base 200 stops working, and the controller 500 controls the locking port 331 of the opening and closing component 300 to open from the second preset position to the first preset position, and the knife handle 1 is taken out.

[0042] In addition, after step S6, the cleaned handle 1 can be placed in the ultrasonic cleaning tank 900 for cleaning. After ultrasonic cleaning, the handle 1 can be placed in the drying tank 910 and the dryer 911 can be started for drying.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention.
