Abstract
Description
Technical Field
[0001] This application relates to the technical field of fasteners, and in particular to a fastener cleaning device. Background Technology
[0002] Fasteners (bolts, nuts, screws, etc.) are the "skeleton connectors" of industrial assembly. Their function is not only physical fixation, but also plays a crucial role in transferring loads and maintaining structural integrity. Data shows that fasteners are widely used in high-precision fields such as automotive, aerospace, and machinery manufacturing. However, their tiny dimensions and complex surfaces (such as thread gaps and blind holes) easily trap contaminants. These seemingly minor contaminants can trigger a chain reaction of failures; therefore, cleaning fasteners is a fundamental prerequisite for ensuring their functionality.
[0003] Currently, commonly used fastener cleaning methods are either physical cleaning methods, such as directly spraying water onto the fasteners to break down, decompose, and peel off dirt using mechanical force and energy, or chemical cleaning methods, such as using chemical agents or aqueous solutions to chemically transform, dissolve, and peel off contaminants on the object's surface. However, regardless of the method, workers need to have direct contact with the fasteners, which often requires them to wear appropriate protective gear, making the work inconvenient. Furthermore, this protective gear needs frequent cleaning and replacement, which is time-consuming, labor-intensive, and results in high production costs. Utility Model Content
[0004] To reduce the difficulty of fastener cleaning and improve cleaning efficiency, this application provides a fastener cleaning device.
[0005] This application provides a fastener cleaning device, which adopts the following technical solution:
[0006] A fastener cleaning device includes a frame and a worktable mounted on the frame. A cleaning tank is provided on the worktable, and fasteners are placed in the cleaning tank. A spray pipe is provided on the worktable for spraying water or chemical solution onto the surface of the fasteners. A brushing mechanism is provided on the frame for brushing the surface of the fasteners. A protective cover is rotatably mounted on the frame to cover the cleaning tank.
[0007] By adopting the above technical solution, the fasteners to be cleaned are placed into the cleaning tank, and then the protective cover is rotated to cover the workbench. Water or chemical solution is then sprayed onto the surface of the fasteners using a spray pipe. At the same time, the cleaning mechanism is activated and works in conjunction with the spray pipe to scrub the surface of the fasteners, thus completing the cleaning work. The entire cleaning process does not require personnel to come into contact with the fasteners, and the protective cover isolates the cleaning tank from the external work area, making the cleaning work convenient, quick, and clean.
[0008] Optionally, the cleaning mechanism includes:
[0009] A fixing seat is provided on the workbench and located in the cleaning tank. The fixing seat has a "V"-shaped placement groove, and the fastener is placed in the placement groove.
[0010] A washing plate, which is vertically slidably mounted on a frame located above the workbench, and has bristles evenly distributed on its bottom;
[0011] A drive assembly, which is mounted on a frame and is used to drive the scrubbing plate to move vertically;
[0012] A rotating assembly, which is mounted on a worktable and is used to drive a fastener located on a fixed base to rotate.
[0013] By adopting the above technical solution, the fastener is placed in the placement slot of the fixed seat to fix its position. Then, the drive component is started to move the brush plate until the bristles on the brush plate come into contact with the fastener. Then, the rotation component is started to rotate the fastener, thereby completing the cleaning work on the surface of the fastener.
[0014] Optionally, the driving component includes:
[0015] A drive electric cylinder is mounted on the frame and its output shaft is vertically downward and connected to the wash plate.
[0016] Two guide rods are vertically slidably mounted on the frame and located on both sides of the drive cylinder in the horizontal direction. The bottom of both guide rods is connected to the wash plate.
[0017] By adopting the above technical solution, two guide rods are slidably installed on the frame to guide the movement direction of the washing plate, so that the washing plate can be controlled to move in the vertical direction after the drive cylinder is started, thus completing the driving work of driving the washing plate to move.
[0018] Optionally, the rotating component includes:
[0019] The first rotating shaft is rotatably mounted on the worktable;
[0020] A rotary motor, wherein the rotary motor is mounted on a worktable and its output shaft is connected to a first rotating shaft;
[0021] An electric push rod is mounted on a worktable, and the electric push rod and the first rotating shaft are located on opposite sides of the fastener's axial direction, respectively.
[0022] The second rotating shaft is rotatably mounted on the electric push rod. Under the action of the electric push rod, the second rotating shaft cooperates with the first rotating shaft to clamp the fastener.
[0023] By adopting the above technical solution, the electric push rod starts and drives the second rotating shaft to move, so that the second rotating shaft contacts the fastener. After the second rotating shaft contacts the fastener, it drives the fastener to move until the other end of the fastener abuts against the first rotating shaft. The first rotating shaft and the second rotating shaft cooperate to fix the fastener in the placement groove of the fixing seat. Then, the rotary motor starts and drives the first rotating shaft to rotate. The rotation of the first rotating shaft can drive the fastener and the second rotating shaft to rotate, thereby completing the driving work of driving the fastener to rotate.
[0024] Optionally, a first reduction sprocket is provided on the first rotating shaft, and a second reduction sprocket is provided on the output shaft of the rotary motor. The diameter of the first reduction sprocket is larger than the diameter of the second reduction sprocket, and a transmission chain is sleeved on the first reduction sprocket and the second reduction sprocket.
[0025] By adopting the above technical solution, the output shaft of the rotary motor is connected to the first rotating shaft through a first reduction sprocket, a second reduction sprocket, and a transmission chain, thereby reducing the speed transmitted from the rotary motor to the first rotating shaft. This reduces the speed of the fastener, making the fastener cleaning process more stable and safe, and ensuring the integrity of the fastener.
[0026] Optionally, several sets of combinations of the first rotating shaft, the electric push rod, and the second rotating shaft are arranged. Several sets of combinations of the first rotating shaft, the electric push rod, and the second rotating shaft are evenly distributed along the bottom surface of the cleaning tank. Each of the upper ends of the first rotating shaft is provided with a transmission gear. The transmission gears on two adjacent first rotating shafts mesh with each other. The first reduction sprocket is arranged on one of the first rotating shafts.
[0027] By adopting the above technical solution, and setting up several combinations of first rotating shafts, electric push rods, and second rotating shafts, multiple fasteners can be placed in the cleaning tank at the same time for cleaning, which greatly improves the cleaning efficiency.
[0028] Optionally, a drain pipe is provided at the bottom of the workbench, the drain pipe is connected to the inside of the cleaning tank, and an electric switch valve is provided on the drain pipe.
[0029] By adopting the above technical solution, a drain pipe is installed at the bottom of the workbench, and the drain pipe can be controlled by the electric switch valve to discharge the liquid sprayed by the spray pipe into the cleaning tank and the impurities washed off the fasteners.
[0030] Optionally, the protective cover is made of transparent acrylic material.
[0031] By adopting the above technical solution, the protective cover is made of transparent acrylic material. This allows staff to observe and monitor the cleaning of fasteners inside the cleaning tank even when the cover is over it, facilitating timely start and stop of the fastener cleaning process.
[0032] In summary, this application includes at least one of the following beneficial technical effects:
[0033] 1. After placing the fasteners to be cleaned into the cleaning tank, rotate the protective cover to cover the workbench, and then use the spray pipe to spray water or chemical solution onto the surface of the fasteners. At the same time, the cleaning mechanism is activated to work with the spray pipe to scrub the surface of the fasteners, thus completing the cleaning work of the fasteners. The entire cleaning process does not require the staff to come into contact with the fasteners, and the protective cover isolates the cleaning tank from the external work area, making the cleaning work convenient, fast, and clean.
[0034] 2. By connecting the output shaft of the rotary motor to the first rotating shaft through a first reduction sprocket, a second reduction sprocket, and a transmission chain, the rotational speed transmitted from the rotary motor to the first rotating shaft is reduced, thereby reducing the speed of the fastener, making the fastener cleaning process more stable and safe, and ensuring the integrity of the fastener.
[0035] 3. By setting the protective cover to be made of transparent acrylic material, the staff can still observe and control the cleaning work of the fasteners inside the cleaning tank through the protective cover when the protective cover is covering the cleaning tank, so as to start and stop the cleaning work of the fasteners in a timely manner.

[0039] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2This application will be described in further detail.
[0040] This application discloses a fastener cleaning device.
[0041] Reference Figure 1 The fastener cleaning device includes a frame 1 and a workbench 11 fixedly mounted on the frame 1. A cleaning tank 12 is provided on the workbench 11, and fasteners are placed inside the cleaning tank 12. A spray pipe 13 is fixedly mounted on the side wall of the workbench 11. One end of the spray pipe 13 is located outside the workbench 11 and connected to a liquid source, while the other end extends into the cleaning tank 12. The spray pipe 13 is used to spray water or chemical solution onto the surface of the fasteners. A brushing mechanism 2 is provided on the frame 1 for brushing the surface of the fasteners. A protective cover 14 made of transparent acrylic material is rotatably mounted on the frame 1, and the protective cover 14 covers the cleaning tank 12 under its own weight.
[0042] Reference Figure 1 and Figure 2 The cleaning mechanism 2 includes a fixed base 21, a scrubbing plate 22, a drive assembly 23, and a rotating assembly 24. Multiple fixed bases 21 are fixedly installed on the bottom wall of the cleaning tank 12, and are evenly distributed along the length of the cleaning tank 12. A "V"-shaped placement groove 25 is formed on the upper surface of the fixed base 21. Fasteners are placed in the placement groove 25.
[0043] Reference Figure 1 and Figure 2 A scrubbing plate 22 is vertically slidably mounted on a frame 1 located above the worktable 11. Bristles are evenly distributed and fixedly installed on the lower surface of the scrubbing plate 22. A drive assembly 23 is mounted on the frame 1 and is used to drive the scrubbing plate 22 to move vertically. The drive assembly 23 includes a drive cylinder 26 and two guide rods 27. The drive cylinder 26 is fixedly mounted on the frame 1 above the scrubbing plate 22. The output shaft of the drive cylinder 26 is vertically downward and fixedly connected to the upper surface of the scrubbing plate 22. The two guide rods 27 are both vertically slidably mounted on the frame 1 and are located on either side of the drive cylinder 26 in the horizontal direction. The bottom of each guide rod 27 is fixedly connected to the upper surface of the scrubbing plate 22.
[0044] Reference Figure 1 and Figure 2The fasteners to be cleaned are placed into the fixing seat 21 inside the cleaning tank 12 and fixed in position. Then, the protective cover 14 is rotated to cover the worktable 11. After the protective cover 14 covers the worktable 11, the spray pipe 13 sprays water or chemical solution onto the surface of the fasteners. At the same time, the drive cylinder 26 is activated to move the scrubbing plate 22 until the bristles on the scrubbing plate 22 contact the fasteners. Then, the rotating component 24 is activated to rotate the fasteners, thus completing the cleaning of the fastener surface. The entire cleaning process does not require personnel to come into contact with the fasteners, and the protective cover 14 isolates the cleaning tank 12 from the external work area, making the cleaning work convenient, quick, and clean.
[0045] Reference Figure 1 and Figure 2 The rotating assembly 24 includes a first rotating shaft 31, a rotary motor 32, an electric push rod 33, and a second rotating shaft 34. Several of each of the first rotating shaft 31, electric push rod 33, and second rotating shaft 34 are provided, their numbers corresponding to the number of fixed seats 21. The first rotating shaft 31 is rotatably mounted on the upper surface of the worktable 11, and the electric push rod 33 is fixedly mounted on the upper surface of the worktable 11. The first rotating shaft 31 and the electric push rod 33 are located on opposite sides of the length of the fixed seat 21. The second rotating shaft 34 is rotatably mounted on the end of the piston rod of the electric push rod 33 near the fixed seat 21.
[0046] Reference Figure 2 After the fastener is placed on the fixed seat 21, the electric push rod 33 is activated to drive the second rotating shaft 34 to move, so that the second rotating shaft 34 contacts the fastener. After the second rotating shaft 34 contacts the fastener, it drives the fastener to move until the other end of the fastener abuts against the first rotating shaft 31. The first rotating shaft 31 and the second rotating shaft 34 cooperate to fix the fastener in the placement groove 25 of the fixed seat 21.
[0047] Reference Figure 2 A rotary motor 32 is fixedly mounted on the outer wall of the worktable 11. A second reduction sprocket 36 is fixedly mounted on the output shaft of the rotary motor 32. A first reduction sprocket 35 is fixedly mounted on the end of one of the plurality of first rotating shafts 31 away from the fixed base 21. A transmission chain 37 is sleeved on the first reduction sprocket 35 and the second reduction sprocket 36. A transmission gear 38 is fixedly mounted on the end of each of the plurality of first rotating shafts 31 away from the fixed base 21, and the transmission gears 38 on adjacent first rotating shafts 31 mesh with each other.
[0048] Reference Figure 2After the first rotating shaft 31 and the second rotating shaft 34 clamp the fastener, the rotary motor 32 starts and drives the second reduction sprocket 36 to rotate. The rotation of the second reduction sprocket 36 drives the transmission chain 37 to rotate. The rotation of the transmission chain 37 drives the first reduction sprocket 35 to rotate. The rotation of the first reduction sprocket 35 drives the first rotating shaft 31 to rotate. The rotation of the first rotating shaft 31 drives the fastener and the second rotating shaft 34 to rotate. Thus, the rotation of the fastener is achieved by controlling the rotary motor 32.
[0049] Reference Figure 2 The output shaft of the rotary motor 32 is connected to the first rotating shaft 31 through the first reduction sprocket 35, the second reduction sprocket 36 and the transmission chain 37, thereby reducing the speed transmitted from the rotary motor 32 to the first rotating shaft 31, thus reducing the speed of the fastener, making the fastener cleaning process more stable and safe, and ensuring the integrity of the fastener.
[0050] Reference Figure 1 and Figure 2 A drain pipe 15 is fixedly installed on the lower surface of the workbench 11, and the drain pipe 15 is set vertically. The top of the drain pipe 15 connects vertically upward to the inside of the cleaning tank 12. An electric switch valve 16 is fixedly installed on the drain pipe 15. By controlling the electric switch valve 16, the drain pipe 15 can discharge the liquid sprayed into the cleaning tank 12 by the spray pipe 13 and the impurities washed from the fasteners.
[0051] The working principle of this application embodiment is as follows:
[0052] After the fasteners are placed into the fixing seat 21 inside the cleaning tank 12 and secured in position, the protective cover 14 is rotated to cover the workbench 11. Once the protective cover 14 covers the workbench 11, the spray pipe 13 sprays water or chemical solution onto the surface of the fasteners. Simultaneously, the drive cylinder 26 starts, moving the scrubbing plate 22 until the bristles on the scrubbing plate 22 contact the fasteners. Then, the rotary motor 32 starts, causing the fasteners to rotate, thus completing the cleaning of the fastener surface. Throughout the cleaning process, no contact between the worker and the fasteners is required, and the protective cover 14 isolates the cleaning tank 12 from the external work area, making the cleaning process convenient, quick, and thoroughly clean.
[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
