Description

Technical Field

[0001] This invention relates to the field of metal parts cleaning technology, specifically to a device for cleaning oil stains on the surface of metal parts. Background Technology

[0002] Current methods for cleaning metal parts used on some rail vehicles mostly involve high-pressure water guns or warm water rinsing, which cannot thoroughly remove oil stains from the surface of the metal parts, resulting in poor cleaning effects. Some methods use brushes to clean the surface of metal parts, but the structure of these brushes generally cannot be adjusted to the shape of the metal parts' surface, leading to incomplete contact between the brush and the surface during cleaning and resulting in inadequate cleaning. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a device for cleaning oil stains on the surface of metal parts, which has the advantages of being easy to apply to cleaning the surfaces of parts with various shapes and improving applicability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a device for cleaning oil stains on the surface of metal parts, comprising: A cleaning tank, with a placement platform inside; A movable platform is movably mounted on the top surface of the platform.

The cleaning assembly includes a lifting cylinder mounted outside the placement platform. A tilting motor is mounted on the piston rod of the lifting cylinder, and a cleaning brush seat is mounted on the output shaft of the tilting motor. Multiple cleaning brushes are movably mounted on the cleaning brush seat.

[0005] Preferably, a rectangular rotating block is fixedly installed on the output shaft of the rotary motor, and a rectangular groove adapted to the rectangular rotating block is horizontally installed on the bottom surface of the moving disk. The rectangular rotating block is slidably installed in the rectangular groove, so that the rotary motor can drive the moving disk to rotate, thereby facilitating multi-angle cleaning of metal parts placed on the moving disk and improving the cleaning effect.

[0006] Preferably, a groove is provided on the top surface of the placement platform, and guide grooves are horizontally provided on the opposite side walls of the groove. The outer circumferential wall of the moving disk is movably engaged in the opening of the guide groove, and the bottom surface of the moving disk is in contact with the top surface of the placement platform. The horizontal cylinder drives the moving disk to move horizontally, which facilitates multi-angle cleaning of metal parts placed on the moving disk and improves the cleaning effect.

[0007] Preferably, the placement platform is provided with horizontal cylinders on both opposite sides. The piston rod of the horizontal cylinder is provided with a U-shaped push rod. The U-shaped opening of the push rod abuts against the outer peripheral wall of the moving plate. The two ends of the rectangular groove along its length are located inside the U-shaped openings of the two push rods. The horizontal cylinder drives the moving plate to move horizontally, which facilitates multi-angle cleaning of the metal parts placed on the moving plate. At the same time, the two U-shaped push rods can clamp the metal parts placed on the moving plate before cleaning.

[0008] Preferably, both ends of the U-shaped opening of the U-shaped top rod are provided with inverted L-shaped clamping rods, and the vertical ends of the inverted L-shaped clamping rods are provided on the U-shaped opening of the U-shaped top rod, so as to facilitate the clamping of metal parts placed on the moving plate before cleaning by using the two U-shaped top rods.

[0009] Preferably, the inner wall of the cleaning tank is provided with a sliding seat corresponding to a lifting cylinder, and a sliding rod is vertically slidably arranged in the sliding seat. The lifting cylinder is set on the bottom surface of the cleaning tank, and the sliding rod is connected to the piston rod of the lifting cylinder. The flipping motor is set on the side wall of the sliding rod away from the sliding seat.

A positioning bolt is provided, with a positioning bolt threaded onto the internal threaded through hole one, and the positioning bolt is threadedly connected to the corresponding rotating internal threaded through hole one. The brush is positioned at the end of the brush handle away from the fixed shaft. The position of the brush handle can be adjusted according to the different shapes of the metal parts, which helps the brush to make better contact with the surface of the metal parts, thereby improving the cleaning effect of the metal parts.

[0012] Preferably, the cleaning brush seat is provided with a plurality of stabilizing rods corresponding one-to-one with the brush rod. The stabilizing rods move through the brush rod and the fixed shaft away from the cleaning brush seat end. The stabilizing rods are provided with internal threaded through holes two corresponding to the positions of the threaded holes. The positioning bolts are sequentially threaded to the first internal threaded through hole, the threaded hole and the second internal threaded through hole, which facilitates the adjustment of the position of the brush rod and helps to maintain the stability of the position of the brush rod.

[0013] Preferably, the internal threaded through holes are spaced apart along the length of the stabilizer bar, which facilitates the adjustment and fixing of the brush bar position.

[0029] 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.

[0030] Example 1 like Figure 1 , Figures 3 to 6As shown, the present invention provides a device for cleaning oil stains on the surface of metal parts, including a cleaning tank 1, a placement platform 2 disposed in the cleaning tank 1; a movable platform 3 movably disposed on the top surface of the placement platform 2; cleaning brush assemblies 4 are disposed on opposite sides of the placement platform 2; the movable platform 3 includes a rotating motor 31 embedded in the top surface of the placement platform 2, and a movable disk 32 is disposed on the output shaft of the rotating motor 31; the cleaning brush assembly 4 includes a lifting cylinder 41 disposed outside the placement platform 2, a tilting motor 42 is disposed on the piston rod of the lifting cylinder 41, a cleaning brush seat 43 is disposed on the output shaft of the tilting motor 42, and a plurality of cleaning brushes 44 are movably disposed on the cleaning brush seat 43.

[0031] Before cleaning, the metal parts are placed on the movable plate 32 in the movable platform 3 (spray heads can be installed on the top and inner wall of the cleaning tank 1, with the spray heads facing the placement platform 2; the spray heads are existing technology and will not be described in detail here, nor are they shown in the attached drawings); during cleaning, the rotating motor 31 can be started to drive the movable plate 32 to rotate, thereby driving the metal parts to rotate, which is beneficial for cleaning the surface of the metal parts and improving the cleaning effect, thus avoiding or eliminating cleaning blind spots; the lifting cylinder 41 can drive the tilting motor 42, the cleaning brush seat 43 and the cleaning brush 44 to adjust their positions in the vertical direction at the same time, thereby facilitating the cleaning of the surface of metal parts at different heights and improving applicability.

[0032] Meanwhile, a horizontal cylinder can be installed at the bottom of the cleaning tank 1, and the lifting cylinder 41 is installed on the piston rod of the horizontal cylinder, so that metal parts of a larger range can be cleaned (that is, the lifting cylinder 41 can be moved horizontally by the horizontal cylinder, so that the distance between the two cleaning components 4 can be adjusted according to the different outer width dimensions of the metal parts).

[0033] Example 2 Based on Example 1, such as Figures 1 to 6As shown, a rectangular rotating block 33 is fixedly mounted on the output shaft of the rotating motor 31. A rectangular groove 34, which is adapted to the rectangular rotating block 33, is horizontally mounted on the bottom surface of the moving disk 32. The rectangular rotating block 33 is slidably mounted in the rectangular groove 34. A groove 21 is provided on the top surface of the placement platform 2. Guide grooves 22 are horizontally mounted on the opposite side walls of the groove 21. The outer circumferential wall of the moving disk 32 is movably locked in the opening of the guide groove 22, and the bottom surface of the moving disk 32 is in contact with the top surface of the placement platform 2. Horizontal cylinders 23 are provided on the other two opposite sides of the placement platform 2. A U-shaped push rod 24 is provided on the piston rod of the horizontal cylinder 23. The U-shaped opening of the U-shaped push rod 24 abuts against the outer circumferential wall of the moving disk 32, and the two ends of the rectangular groove 34 in the length direction are located in the U-shaped openings of the two U-shaped push rods 24. The horizontal cylinder 23 drives the moving disk 32 to move horizontally.

[0034] Before cleaning, place the metal parts on the movable plate 32 in the movable table 3. When it is necessary to rotate the metal parts during cleaning, start the two horizontal cylinders 23 simultaneously to move the U-shaped push rod 24 towards the movable plate 32. When the U-shaped opening of the U-shaped push rod 24 abuts against the outer peripheral wall of the movable plate 32, as the U-shaped push rod 24 continues to move and the movable plate 32 is positioned, the movable plate 32 moves to the position of the rectangular rotating block 33 (when the movable plate 32 moves horizontally for position adjustment, the outer peripheral wall of the movable plate 32 can move within the opening of the guide groove 22, thus maintaining the accurate position of the movable plate 32). At this time, the rectangular rotating block 33 on the output shaft of the rotating motor 31 can be inserted into the rectangular groove 34 on the bottom surface of the movable plate 32 (both ends of the rectangular groove 34 are located on the movable plate 32). On the outer peripheral wall of 2, it is convenient for the rectangular rotating block 33 to slide into the rectangular groove 34 or for the rectangular rotating block 33 to slide out of the rectangular groove 34); then start the rotating motor 31 to drive the rectangular rotating block 33 to rotate. Since the rectangular rotating block 33 is located in the rectangular groove 34, it can drive the moving disk 32 to rotate (and when the moving disk 32 rotates, the outer peripheral wall of the moving disk 32 can rotate in the opening of the guide groove 22); thus, the outer surface of the metal parts can be cleaned by the cleaning brush 44; and spheres can be rotatably embedded in both ends of the U-shaped opening of the U-shaped top rod 24, so that when the rotating motor 31 is started to drive the moving disk 32 to rotate, the spheres in the U-shaped opening of the U-shaped top rod 24 can maintain the position of the moving disk 32 when it rotates, and will not interfere with the rotation of the moving disk 32.

[0035] When it is not necessary for the metal parts to rotate during cleaning (but it is necessary for the metal parts to move back and forth in a straight line), the rotating motor 31 can be started to drive the rectangular rotating block 33 to rotate, so that the length direction of the rectangular rotating block 33 is the same as the length direction of the guide groove 22 (at this time, the length direction of the rectangular rotating block 33 is the same as the extension and retraction direction of the piston rod of the horizontal cylinder 23); then the two horizontal cylinders 23 can extend and retract alternately in sequence, and under the action of the U-shaped top rod 24, the moving plate 32 can move back and forth in a straight line in the groove 21 on the top surface of the placement platform 2.

[0036] Both ends of the U-shaped opening of the U-shaped top rod 24 are provided with inverted L-shaped clamping rods 241, and the vertical end of the inverted L-shaped clamping rods 241 is set on the U-shaped opening of the U-shaped top rod 24. When the two horizontal cylinders 23 are activated to drive the U-shaped top rod 24 to move closer to the moving plate 32, after the U-shaped opening of the U-shaped top rod 24 abuts against the outer peripheral wall of the moving plate 32, the metal parts placed on the moving plate 32 can be clamped and fixed by the horizontal end of the inverted L-shaped clamping rods 241, which is beneficial to maintain the stability of the position when cleaning the metal parts (the horizontal end of the inverted L-shaped clamping rods 241 can be a pneumatic telescopic rod structure, which is convenient for clamping and fixing metal parts of different shapes and sizes. The pneumatic telescopic rod is existing technology, so it will not be described in detail here).

[0037] Example 3 Based on Example 1, such as Figures 3 to 6 As shown, the inner wall of the cleaning tank 1 is provided with a sliding seat 5 corresponding to a lifting cylinder 41. A sliding rod 51 is vertically slidably installed in the sliding seat 5. The lifting cylinder 41 is set on the bottom surface of the cleaning tank 1. The sliding rod 51 is connected to the piston rod of the lifting cylinder 41. The flipping motor 42 is set on the side wall of the sliding rod 51 away from the sliding seat 5. Before cleaning, after the metal parts are placed on the moving plate 32 in the moving table 3, the lifting cylinder 41 can be activated to drive the sliding rod 51 to adjust its position in the vertical direction according to the height of the metal parts. At this time, the sliding rod 51 can slide vertically in the sliding seat 5. Under the guiding and limiting action of the sliding seat 5, the sliding rod 51 can move in the vertical direction and maintain a stable position (that is, the lifting cylinder 41 can simultaneously drive the flipping motor 42, the cleaning brush seat 43 and the cleaning brush 44 to adjust their positions in the vertical direction at the same time). This makes it easier to clean different positions of the metal parts by the cleaning brush 44, improving applicability and cleaning effect.

[0038] Example 4 Based on Example 1, such as Figure 3 , Figures 5 to 9As shown, a cleaning brush holder 43 is provided with a cleaning brush groove 431 at the end away from the flip motor 42, and cleaning brushes 44 are arranged in parallel within the cleaning brush groove 431. Each cleaning brush 44 includes a fixed shaft 441, which is located within the cleaning brush groove 431. The fixed shaft 441 has multiple threaded holes 4411, each corresponding to a cleaning brush 44, spaced along its length. Brush rods 442 are arranged in parallel within the cleaning brush groove 431, and an adjustment groove 443 is provided on the brush rod 442 near the end of the fixed shaft 441. The fixed shaft 441 passes through the adjustment groove 443. Multiple internal threaded through holes 444 are provided, and multiple internal threaded through holes 444 are arranged in parallel on the opposite side walls of the adjustment groove 443. A positioning bolt 445 is threadedly connected to the internal threaded through hole 444, and the positioning bolt 445 is threadedly connected to the corresponding internal threaded through hole 444. A brush 446 is located at the end of the brush rod 442 away from the fixed shaft 441.

[0039] The position of the cleaning brush 44 on the brush holder 43 can be adjusted according to the shape of the metal parts, so that the brush 446 can better contact the surface of the metal parts. That is, when the surface of the metal parts is flat, the position of the brush rod 442 can be adjusted by sliding on the fixed shaft 441 (so that the fixed shaft 441 can move to different positions in the adjustment groove 443). Then, the positioning bolt 445 passes through the internal threaded through hole 444 on the adjustment groove 443 and the threaded hole 4411 on the fixed shaft 441 and is threadedly connected to the internal threaded through hole 61 on the stabilizer rod 6. At this time, the brush 446 can be distributed in a planar shape, so that the surface of the metal parts can be cleaned in the vertical direction under the action of the lifting cylinder 41.

[0040] When the surface of the metal parts is flat and arc-shaped, the position of each brush rod 442 can be adjusted by sliding on the fixed shaft 441 (so that the fixed shaft 441 can be moved to different positions in the adjustment groove 443). Then, the positioning bolt 445 is threaded through the internal threaded through hole 444 on the adjustment groove 443 and the threaded hole 4411 on the fixed shaft 441 and threadedly connected to the internal threaded through hole 61 on the stabilizer rod 6. At this time, the brushes 446 can be distributed in an arc shape, so that the surface of the metal parts can be cleaned in the vertical direction under the action of the lifting cylinder 41, so that the brushes 446 can better contact the surface of the metal parts and improve the surface cleaning effect of the metal parts.

[0041] Example 5 Based on Example 1, such as Figures 6 to 10As shown, the cleaning brush base 43 is provided with multiple stabilizing rods 6 corresponding one-to-one with the brush rod 442. The stabilizing rod 6 passes through the brush rod 442 and the fixed shaft 441 at the end away from the cleaning brush base 43. The stabilizing rod 6 is provided with an internal threaded through hole 61 corresponding to the position of the threaded hole 4411. The positioning bolt 445 is threadedly connected to the internal threaded through hole 444, the threaded hole 4411 and the internal threaded through hole 61 in sequence. When the position of the brush rod 442 is adjusted by sliding on the fixed shaft 441, the stabilizing rod 6 can play a stabilizing role and prevent the brush rod 442 from rotating on the fixed shaft 441. This helps to maintain the stability of the position of the brush rod 442 and makes it easy to fix the position of the brush rod 442 after adjustment. That is, after the position of the brush rod 442 is adjusted, the positioning bolt 445 passes through the internal threaded through hole 444 on the adjustment groove 443 and the threaded hole 4411 on the fixed shaft 441 and is threadedly connected to the internal threaded through hole 61 on the stabilizing rod 6.

[0042] The internal threaded through holes 444 are spaced apart along the length of the stabilizer rod 6; this facilitates the sliding adjustment of the position of the brush rod 442 on the fixed shaft 441, and then the positioning bolt 445 passes through the internal threaded through holes 444 and the threaded hole 4411 and is threadedly connected to the internal threaded through hole 61 at the corresponding position.

[0043] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
