Description

Technical Field

[0001] This utility model belongs to the technical field of parts cleaning equipment, and more specifically relates to a low-pressure cleaning mechanism. Background Technology

[0002] After machining, parts need to be surface cleaned to remove surface debris and dirt. The traditional cleaning method is to place the parts directly in the cleaning chamber and use high-pressure nozzles inside the chamber to spray high-pressure cleaning fluid onto the parts. However, the surface of freshly machined parts will have large debris and other fixed objects attached to it, and the debris is mostly cutting debris with relatively sharp edges. Therefore, when it is rinsed by high-pressure cleaning fluid, it may rub against the parts, especially in the holes or grooves of the parts. The debris is not easy to be discharged and will be repeatedly washed by the high-pressure cleaning fluid and repeatedly collide with the parts, causing damage to the surface of the parts and affecting the quality of the finished parts. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a low-pressure cleaning mechanism that performs pre-cleaning of parts before high-pressure cleaning, removing larger debris from the surface of the parts and preventing damage to the surface of the parts during cleaning.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-pressure cleaning mechanism, comprising a cleaning chamber, an annular support plate disposed within the cleaning chamber, the annular support plate being rotatably connected to the cleaning chamber, a driving mechanism connected to the annular support plate, a plurality of support blocks and a plurality of positioning pins disposed on the annular support plate, a nozzle assembly disposed within the cleaning chamber, the nozzle assembly comprising a first nozzle located on the opposite side of the annular support plate, a second nozzle located at the bottom of the annular support plate, and a third nozzle located above the annular support plate, wherein the first nozzle, the second nozzle, and the third nozzle are all low-pressure nozzles, and a plurality of nozzles arranged along the nozzle axis are disposed on the first nozzle, the second nozzle, and the third nozzle.

[0005] Furthermore, the driving mechanism includes a hollowed-out rotating platform and a driving cylinder. The annular support plate is connected to the rotating platform, and the rotating platform is rotatably connected to the cleaning tank. A rotating shaft is provided on the rotating platform. A rack is provided on the piston rod of the driving cylinder. A gear that meshes with the rack is provided on the rotating shaft. The rack is slidably connected to the cleaning tank. A locking mechanism and a rotation sensing mechanism are connected to the rotating shaft.

[0006] Furthermore, the locking mechanism includes a locking plate located on the rotating shaft, the locking plate being provided with a locking hole, a locking cylinder being provided on the cleaning chamber, and a locking block corresponding to the locking hole being provided on the piston rod of the locking cylinder.

[0007] Furthermore, the rotary sensing mechanism includes several sensing plates located on the rotating shaft, and sensors are provided on the cleaning tank.

[0008] Furthermore, a water tank is provided on one side of the cleaning box, and a water outlet connected to the water tank is provided at the bottom of the cleaning box. A filter screen is provided in the water tank corresponding to the water outlet, and a water pump is provided on the water tank. The water pump is connected to a spray pipe assembly.

[0009] Furthermore, the top of the cleaning chamber is provided with an opening, and a top sealing cover is provided on one side of the opening. The top sealing cover is hinged to the cleaning chamber, and a driving device is connected to the top sealing cover. The third spray pipe is located on the top sealing cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: During cleaning, the parts are placed directly on the annular tray and positioned by several positioning pins on the annular tray. At the same time, the support block supports the parts, leaving a gap between them and the annular tray. Then, cleaning fluid is sprayed onto the parts through the first, second, and third spray pipes. Simultaneously, the drive mechanism drives the annular tray to rotate, thereby cleaning the parts from all angles. Because low-pressure water spray is used, it can effectively prevent waste debris from being subjected to large impacts and colliding with the surface of the parts, causing damage.

[0019] Reference Figures 1 to 5 The utility model is further described.

[0020] A low-pressure cleaning mechanism includes a cleaning chamber 1, an annular support plate 2 disposed inside the cleaning chamber 1, the annular support plate 2 being rotatably connected to the cleaning chamber 1, a driving mechanism 3 connected to the annular support plate 2, a plurality of support blocks 4 and a plurality of positioning pins 5 disposed on the annular support plate 2, and a nozzle assembly 6 disposed inside the cleaning chamber 1, the nozzle assembly 6 including a first nozzle 7 located on the opposite side of the annular support plate 2, a second nozzle 8 located at the bottom of the annular support plate 2, and a third nozzle 9 located above the annular support plate 2, wherein the first nozzle 7, the second nozzle 8 and the third nozzle 9 are all low-pressure nozzles, and a plurality of nozzles 10 arranged along the nozzle axis are disposed on the first nozzle 7, the second nozzle 8 and the third nozzle 9.

[0021] like Figures 1 to 5 As shown, during cleaning, the parts are placed directly on the annular support plate 2 and positioned by several positioning pins 5 on the annular support plate 2. At the same time, the support block 4 supports the parts, leaving a gap between them and the annular support plate 2. Then, cleaning fluid is sprayed onto the parts through the first spray pipe 7, the second spray pipe 8, and the third spray pipe 9. Simultaneously, the drive mechanism 3 drives the annular support plate 2 to rotate, thereby cleaning the parts from all angles. Because low-pressure water spray is used, the cleaning process can effectively avoid the waste debris from being impacted and colliding with the surface of the parts, causing damage. After the parts are rinsed with low pressure, they are transferred to the high-pressure cleaning chamber for high-pressure rinsing, which is the pre-cleaning before high-pressure cleaning.

[0022] Waste chips are not easily discharged and are repeatedly washed by the high-pressure cleaning fluid, causing repeated impacts and contact with the parts, resulting in surface damage and affecting the quality of the finished product.

[0023] like Figure 3 As shown in the preferred embodiment, the driving mechanism 3 includes a hollowed-out rotating platform 11 and a driving cylinder 12.

A locking mechanism and a rotation sensing mechanism are connected to the rotating shaft 13.

[0024] Specifically, the drive cylinder 12 drives the rack 14 to move, thereby causing the gear 15 to rotate, which in turn drives the annular tray 2 inside the cleaning box 1 to rotate. The rotation sensing mechanism detects the rotation angle, and after rotating to a certain angle, it can be locked by the locking mechanism.

[0025] like Figure 3 As shown, in this preferred embodiment, the locking mechanism includes a locking plate 16 located on the rotating shaft 13, the locking plate 16 is provided with a locking hole 17, the cleaning box 1 is provided with a locking cylinder 18, and the piston rod of the locking cylinder 18 is provided with a locking block 19 corresponding to the locking hole 17.

[0026] Specifically, when the locking plate 16 rotates with the rotating shaft 13 until the lock hole 17 is aligned with the locking block 19, the piston rod of the locking cylinder 18 extends and inserts the locking block 19 into the lock hole 17, thereby locking the rotating shaft 13.

A filter screen (not shown in the attached figure) is provided in the water tank 21 at the corresponding water outlet. A water pump 22 is provided on the water tank 21, and the water pump 22 is connected to the spray pipe assembly 6.

[0029] Specifically, the cleaning fluid falling from the parts enters the water tank 21 through the outlet below. As it passes through the filter screen, fixed impurities in the cleaning fluid are filtered out. The water pump 22 delivers the cleaning fluid in the water tank 21 to the spray nozzle assembly 6.

[0030] Specifically, the water tank 21 is equipped with an oil skimmer to remove oil floating on the water surface inside the water tank 21, so as to prevent it from being sprayed onto the surface of the parts by the spray nozzle assembly 6.

[0031] Specifically, the water tank 21 is equipped with a water level detection mechanism to detect the water level in the water tank 21. When the water level in the water tank 21 decreases, water is added to the narcissus tube.

[0032] like Figure 1 and Figure 2 As shown in the example, preferably, the top of the cleaning chamber 1 is provided with an opening, and a top sealing cover 23 is provided on one side of the opening. The top sealing cover 23 is hinged to the cleaning chamber 1, and a driving device is connected to the top sealing cover 23. The third spray pipe 9 is located on the top sealing cover 23.

[0033] Specifically, the driving device includes a sealing cylinder 24, the cylinder body of the sealing cylinder 24 is hinged to the cleaning box 1, and the piston rod of the sealing cylinder 24 is hinged to the top sealing cover 23. The sealing cylinder 24 realizes the automatic opening and closing of the top sealing cover 23.
