Description

Technical Field

[0001] This utility model relates to the field of screw cleaning technology, and in particular to a screw assembly pre-coating cleaning device. Background Technology

[0002] Screw cleaning equipment is a specialized device used to remove oil, impurities, and oxide layers from the surface of screws. It is widely used in automotive parts, aerospace, industrial machinery, and other fields. Spray cleaning machines, in particular, use a high-pressure spray system to directly spray cleaning fluid onto the screw surface in the form of a high-pressure jet, washing away the dirt.

[0003] The existing utility model patent with publication number CN222035971U discloses a high-efficiency cleaning device for screw surfaces. It states that "by setting up a water receiving shell, a rotating clamping assembly, a water tank, a water pump, a water suction pipe, an L-shaped plate, a water outlet pipe, multiple branch water pipes, and a spray head, the screw can be cleaned relatively conveniently and quickly. By setting up a hot air blower, an air outlet pipe, multiple branch air pipes, and an air hood, the cleaned screw can be quickly dried, making it convenient and beneficial to improving production efficiency." Although this solves the problem of "manual cleaning by hand using cleaning tools, which is time-consuming, labor-intensive, and inefficient," the device can only clean a single screw at a time. Cleaning a large number of screws takes a long time, resulting in relatively low overall efficiency and making it difficult to meet the needs of high-efficiency production. Therefore, a pre-coating cleaning device for screw components is proposed. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A pre-coating cleaning device for screw assembly includes a cleaning tank 1, an mounting plate 2 fixedly connected to one side of the top of the cleaning tank 1, and a water spraying device 3 installed on the top of the inner wall of the mounting plate 2 for spraying cleaning liquid onto the screw surface and pre-rinsing the screw surface with high-pressure water flow to remove some dirt.

[0034] Two device plates 4 are L-shaped and are placed on top of the cleaning tank 1. Multiple mounting holes 5 are provided on the surface of the device plates 4 to provide mounting space for the rotating block 6. The rotating block 6 is installed in the inner cavity of the mounting hole 5 and can rotate under the drive of the drive component 10, thereby driving the screw to rotate. Two positioning blocks 7 are fixedly connected to one side wall of the rotating block 6. The positioning blocks 7 are arc-shaped. The length of the top positioning block 7 is shorter than that of the bottom positioning block 7 to facilitate the placement of the screw. The inner wall of the mounting hole 5 is provided with an annular groove 13. The outer wall of the rotating block 6 is fixedly connected with a fixing ring 14. The rotating block 6 is rotatably connected to the inner cavity of the mounting hole 5 through the fixing ring 14 and the annular groove 13. The positioning blocks 7 are arc-shaped and several ball bearings 15 are embedded in the inner side wall of the positioning blocks 7. The two device plates 4 are symmetrically distributed.

[0035] The drive unit 8, specifically a cylinder, provides driving force for the movement of the right-side device plate 4. The drive unit 8 is installed on one side wall of the cleaning tank 1. The other side wall of the multiple rotating blocks 6 on the right side is fixedly connected to a worm gear 9, which is used to transmit the rotation of the worm 103 to the rotating block 6, thereby driving the screw to rotate. A drive component 10 is provided on one side of the right-side device plate 4.

[0036] Preferably, the left device plate 4 is fixedly connected to one side of the inner wall of the cleaning tank 1, and a movable groove 11 is provided on one side of the right device plate 4. A fixed plate 12 is fixedly connected to the other side of the inner wall of the cleaning tank 1. The fixed plate 12 is slidably connected to the inner cavity of the movable groove 11. The movable groove 11 and the fixed plate 12 play a role in limiting and guiding the right device plate 4.

[0037] Preferably, the output end of the drive unit 8 is connected to the right device plate 4 via a transmission connection. The drive unit 10 includes side blocks 101 respectively fixed to the two side walls of the right device plate 4. One side wall of one of the side blocks 101 is equipped with a drive unit 2 102, specifically a motor, which provides driving force for the rotation of the worm 103. The output shaft of the drive unit 2 102 rotates through the surface of the side block 101 on the same side and is connected to the worm 103 via a transmission connection. One end of the worm 103 is rotatably connected to the surface of the other side block 101. The worm 103 meshes with the worm wheel 9. The drive unit 2 102 drives the worm 103 to rotate, and the worm 103 drives the worm wheel 9 to rotate, thereby driving the rotating block 6 and the screw to rotate, thereby achieving comprehensive cleaning of the screw surface.

[0038] Preferably, a plurality of mounting cylinders 16 and moving rods 18 are provided between the two device plates 4. The mounting cylinders 16 are fixedly connected to the left device plate 4, and the moving rods 18 are fixedly connected to the right device plate 4. One end of the moving rods 18 is slidably connected to the inner cavity of the mounting cylinders 16. A top hole 17 is provided on one side of the top of the mounting cylinder 16 to provide moving space for the brush bristles 19 on the top of the moving rods 18 so that the brush bristles 19 on the mounting cylinders 16 and the moving rods 18 can be combined. The top ends of the mounting cylinders 16 and the moving rods 18 are both fixedly connected with brush bristles 19 to brush the dirt on the screw surface.

[0039] The process of using the pre-coating cleaning equipment for screw components provided by this utility model is as follows: First, the operator places the two ends of multiple screws between the two positioning blocks 7 on the two device plates 4 in sequence. Then, the drive unit 1 8 is driven, so that the right device plate 4, under the limiting action of the moving groove 11 and the fixed plate 12, moves the positioning blocks 7 and other components on it to one side until they abut against the screws, thus clamping the screws. At the same time, the moving rod 18 on the right device plate 4 drives the brush bristles 19 on it to merge with the brush bristles 19 on the mounting cylinder 16 through the top hole 17. Then, the drive unit 2 102 is activated, so that the worm gear 103 rotates, which drives the multiple rotating blocks 6 on this side to rotate through the worm wheel 9, thereby making the multiple screws rotate. The water spray device 3 rinses the screws, and the brush bristles 19 brush the screws, thus completing the cleaning of multiple screws.
