Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a process hole cleaning device for workpieces. Background Technology

[0002] Currently, during the production and processing of automotive parts, it is necessary to clean the process holes of automotive parts to improve the cleanliness of automotive parts. Therefore, it is necessary to use workpiece process hole cleaning devices. Usually, after cleaning with these special cleaning equipment, some areas that are difficult to clean completely still need to be manually cleaned by blowing compressed air with an air gun to remove them to meet the requirements.

[0003] A search revealed that publication number CN211516852U describes a hole and groove processing device, comprising: an air-blowing fixture for cleaning foreign objects from workpiece holes; the air-blowing fixture including: a nozzle connected to an air supply device for blowing air into the workpiece hole along its axial direction; and a driving component for driving the nozzle closer to the workpiece hole. This hole and groove processing device, by using an air-blowing fixture, allows the driving component to move the nozzle closer to the workpiece hole. Air is then blown into the workpiece hole along its axial direction through the nozzle connected to the air supply device, causing foreign objects in the workpiece hole to be blown out during processing. This achieves workpiece cleaning, improves cleaning efficiency, and helps reduce abnormalities caused by the presence of foreign objects in subsequent processing.

[0004] The above solution uses pneumatic blowing to clean the workpiece. However, since the workpiece is always placed in a fixed manner, the cleaning effect on porous workpieces is not good. Furthermore, relying solely on pneumatic blowing can easily result in incomplete removal of foreign matter.

[0005] To address this issue, a process hole cleaning device for workpieces is proposed, which has the advantage of easily and thoroughly cleaning foreign objects from the workpiece holes, thereby solving the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a workpiece process hole cleaning device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a workpiece process hole cleaning device, comprising a cleaning box, a viewing window hinged to the front surface of the cleaning box, a servo motor fixed below the viewing window, a shaft fixed to the output end of the servo motor via a coupling, a connecting seat fixed to the surface of the shaft, a clamping platform welded to the top of the connecting seat, water supply pipes inserted through the left and right sides of the cleaning box, and arc pipes connected to the opposite ends of the two water supply pipes, a plurality of high-pressure nozzles installed on the bottom surface of the arc pipe, and the arc pipe being above the clamping platform, a telescopic sleeve embedded in the lower surface of the viewing window, and a control lever inserted through the telescopic sleeve, a wire brush head fixed to one end of the control lever extending into the cleaning box, a support platform welded to the bottom of the cleaning box, and a filter bucket connected to the bottom surface of the support platform.

[0008] As a further description of the above technical solution: the surface of the support platform has a waste discharge port connected to the filter bucket, and the left and right sides of the lower inner side of the cleaning box are respectively welded with slopes corresponding to the waste discharge port. The bottom of the filter bucket is equipped with a filter assembly, which is composed of an activated carbon filter screen and filter cotton. The bottom of the filter bucket is equipped with a funnel-shaped drain nozzle corresponding to the filter assembly.

[0009] As a further description of the above technical solution: a clamping seat is welded on both the left and right sides of the top surface of the clamping platform, and a plum blossom knob is threadedly connected to the surface of the clamping seat. A clamp is rotatably mounted on one end of the plum blossom knob through a shaft seat, and two right-angled triangular limit blocks are symmetrically mounted on the surface of the clamp. The outer surface of the limit blocks of the clamp is covered with a rubber elastic layer.

[0010] As a further description of the above technical solution: the wire brush head is composed of a supporting core rod and wire bristles wrapped on its surface, and the supporting core rod of the wire brush head has a bullet-shaped structure.

[0011] As a further description of the above technical solution: the telescopic sleeve has an overall rectangular structure, and the cross-section of the telescopic sleeve has a wavy structure.

[0012] As a further description of the above technical solution: support legs are welded at the four corners of the bottom surface of the support platform, and a diagonal brace is welded to the upper side of each support leg. A U-shaped cleaning port is provided on the side of the filter hopper of the support platform.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, two water supply pipes and two control levers with wire brush heads are installed inside the cleaning box. Pressurized cleaning water is injected into the arc-shaped pipe through the water supply pipes, causing several high-pressure nozzles on the bottom surface of the arc-shaped pipe to spray the cleaning water onto the workpiece on the clamping table. As a servo motor drives the shaft to rotate, the workpiece on the clamping table can be tilted around the shaft's axis, achieving a comprehensive high-pressure cleaning effect. At this time, by operating the control levers inserted into the telescopic sleeve, combined with the wave-shaped structure of the telescopic sleeve's cross-section, it possesses elastic telescopic characteristics, allowing the wire brush head at one end of the control lever to flexibly penetrate into the workpiece's process holes for manual cleaning. This ensures thorough cleaning of the workpiece while simultaneously providing high-pressure water rinsing. Attached Figure Description
