Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to a cleaning device for automobile hole parts. Background Art

[0002] In the automotive parts manufacturing industry, components with threaded holes, such as bolts, studs, and flanges (hereinafter referred to as "hole-type components"), are widely used. After machining (such as drilling and tapping) these components, iron filings, oil stains, coolant residue, and other small impurities inevitably remain within the thread gaps. Thorough removal of these residues is crucial; otherwise, during subsequent assembly or use, they can lead to poor thread fit, insufficient fastener preload, and even accelerated wear, directly impacting the reliability and overall safety of automotive components.

[0003] At present, the cleaning of threaded holes mainly relies on the following methods: 1. Manual air gun purging: The operator uses a handheld high-pressure air gun to blow air through the threaded hole. This method is inefficient and difficult to meet the needs of mass production. The cleaning effect depends on the operator's experience and responsibility, and it is easy to miss or incomplete the cleaning. More importantly, the high-speed air jet blows debris and dust directly into the work environment, posing a health hazard to the operator (such as inhalation of dust) and contaminating the work area.

[0004] 2. Manual cleaning (e.g., brush): Use a brush or similar tool to manually clean threaded holes. This method is less efficient and less effective for removing stubborn impurities in deep holes or fine threads. It also suffers from high labor intensity and manual labor dependency.

[0005] 3. Some automated equipment: Although some existing automated cleaning equipment attempts to improve efficiency, it still has obvious shortcomings. For example: Poor coordination between feeding and cleaning actions: It is difficult to ensure that each part is accurately and reliably delivered to the cleaning station and its threaded hole is precisely aligned with the cleaning nozzle, resulting in cleaning failure or reduced efficiency.

[0006] Low gas utilization and poor cleaning effect: During the air blowing cleaning process, high-pressure gas easily escapes from the upper end of the threaded hole and cannot effectively act on the deep thread gap. It often requires a longer blowing time or higher air pressure to achieve the cleaning requirements, which wastes energy and has unstable effects.

[0007] Improper debris handling: Debris blown off during the cleaning process is directly discharged or not effectively collected, which can easily spread in the work area, causing secondary pollution, increasing the burden of workshop cleaning, and is not conducive to environmental protection. Summary of the Invention

[0008] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a device for cleaning threaded holes of automobile parts, which is an automated and efficient device for cleaning threaded holes of automobile parts.

[0009] In order to achieve the above object, the present invention is implemented through the following technical solution: a cleaning device for automobile hole parts, comprising: A workbench is provided with a through hole extending vertically therethrough; A feeding device, used to store a plurality of components to be cleaned, and to place the components individually and periodically on the workbench, and to align the threaded holes on the components with the through holes, and then the feeding device transports the cleaned components away from the workbench; and The threaded hole cleaning device includes a high-pressure gas source and a nozzle. The nozzle is located directly above the through hole and aligned with the threaded hole of the component on the support frame. The high-pressure gas source is connected to the nozzle to periodically provide compressed gas to the nozzle.

[0010] Furthermore, the feeding device includes a distribution plate, a rotating power source and a loading barrel. The workbench is also provided with a discharge hole, and the component can pass through the discharge hole. The distribution plate can be rotatably installed on the workbench, and the depth of the notch is less than or equal to the thickness of the component. The rotating power source is used to drive the distribution plate to rotate periodically. Four notches are evenly spaced circumferentially on the distribution plate. When the distribution plate rotates, the four notches can pass through the through hole in turn and then through the discharge hole. The loading barrel is vertically arranged above the distribution plate, and the bottom end of the loading barrel is close to the surface of the distribution plate. The upper and lower ends of the loading barrel are both open, and the components to be cleaned are stacked in the loading barrel from bottom to top.

[0011] Furthermore, it also includes a lifting device, which is connected to the nozzle and is used to drive the nozzle to vertically descend close to the threaded hole on the component on the workbench during blowing.

[0012] Furthermore, it also includes an elastic sealing member, which is sealingly sleeved on the nozzle. When the nozzle descends to the bottom, the sealing member is pressed against the upper end surface of the component.

[0013] Furthermore, it also includes a filtering device, which is arranged in the through hole and is used to filter the air passing through the through hole.

[0014] Furthermore, the filtering device includes a connecting sleeve and a filter screen. The connecting sleeve is detachably arranged in the through hole, and the filter screen is arranged on the connecting sleeve and covers the through hole.

[0015] Furthermore, it also includes an airflow deceleration device, which is arranged at the air outlet end of the through hole and is used to decelerate the airflow passing through the through hole.

[0016] Furthermore, the airflow deceleration device includes a plurality of air guide plates, which are arranged in two groups opposite to each other and staggered in the through hole, and each of the air guide plates is inclined toward the outlet end of the through hole.

[0017] Furthermore, it also includes a material transporting device, the feeding end of which is located directly below the discharge hole, for receiving the components dropped from the discharge hole and transporting the components forward.

[0018] Beneficial effects of the present invention: When the above-mentioned automobile hole parts cleaning device is used, the feeding device first periodically transports the parts to the workbench, and aligns the threaded hole to be cleaned with the through hole. Then, the high-pressure gas source provides compressed gas to the nozzle. The high-pressure compressed gas can blow the residual iron filings and other debris in the thread gap of the threaded hole downward through the through hole. Then the feeding device transports the cleaned parts away and places new parts to be cleaned on the workbench.

[0019] The use of this device has the following beneficial effects: 1. Automatic cleaning to improve efficiency The feeding device automatically and periodically delivers the parts to be cleaned to the workbench one by one, ensuring that the threaded holes and through holes are precisely aligned. At the same time, the high-pressure airflow of the threaded hole cleaning device is used for cleaning, realizing fully automated continuous operation, significantly reducing manual intervention, and greatly improving cleaning efficiency, which is suitable for mass production needs.

[0020] 2. The cleaning effect is stable and reliable The nozzle is located directly above the through hole, and the high-pressure airflow is directly aimed at the threaded hole, ensuring that the airflow can penetrate deep into the thread gap and effectively remove iron filings, oil stains and other residues, avoiding omissions or incomplete cleaning that may occur during manual operation, and the cleaning quality is stable and controllable.

[0021] 3. Reduce environmental pollution and ensure operational safety The debris and dust generated during the cleaning process are discharged downward through the through-holes, avoiding the splashing of debris caused by high-speed airflow, reducing pollution to the working environment, reducing health hazards to operators, and improving the working environment in the workshop.

[0022] 4. Simple structure and easy maintenance The device is mainly composed of a workbench, a feeding device and a threaded hole cleaning device. It has a compact structure, stable operation, is easy to maintain and clean, and reduces equipment maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] See Figures 1 to 3 The present invention provides a cleaning device for automobile hole parts, including a workbench 100, a feeding device 200 and a threaded hole cleaning device 300.

[0027] Specifically, a through-hole 110 is formed on the workbench 100 and extends vertically therethrough. A feeding device 200 is used to store multiple components to be cleaned. It can individually and periodically place the components on the workbench 100, aligning the threaded holes on the components with the through-hole 110. The feeding device 200 then transports the cleaned components away from the workbench 100. The threaded hole cleaning device 300 includes a high-pressure gas source 310 and a nozzle 320. The nozzle 320 is located directly above the through-hole 110 and aligned with the threaded holes of the components on the support frame. The high-pressure gas source 310 is connected to the nozzle 320 to periodically supply compressed gas to the nozzle 320.

[0028] During use, the feeding device 200 first periodically transports the components to the workbench 100 and aligns the threaded hole to be cleaned with the through hole 110. Then, the high-pressure gas source 310 provides compressed gas to the nozzle 320. The high-pressure compressed gas can blow the residual iron filings and other debris in the threaded gap of the threaded hole downward through the through hole 110. Then, the feeding device 200 transports the cleaned components away and places new components to be cleaned on the workbench 100.

[0029] The use of this device can avoid the traditional manual cleaning method, thereby improving work efficiency and preventing the harm of dust to workers during manual cleaning.

[0030] In the present embodiment, the feeding device 200 includes a feed disc 210, a rotary power source 220 and a feed barrel 230. A discharge hole is also provided on the workbench 100, and components can pass through the discharge hole. The feed disc 210 can be rotatably installed on the workbench 100, and the depth of the notch 211 is less than or equal to the thickness of the components. The rotary power source 220 is used to drive the periodic rotation of the feed disc 210. Four notches 211 are evenly spaced circumferentially on the feed disc 210. When the feed disc 210 rotates, the four notches 211 can pass through the through hole 110 in sequence and then pass through the discharge hole. The feed barrel 230 is vertically arranged above the feed disc 210, and the bottom end of the feed barrel 230 is close to the surface of the feed disc 210. The upper and lower ends of the feed barrel 230 are open, and the components to be cleaned are stacked in the feed barrel 230 from bottom to top.

[0031] It should be noted that, in a specific implementation, the rotary power source 220 can be any power source that can drive the material distribution plate 210 to rotate regularly and intermittently. Furthermore, in a specific implementation, the rotation frequency of the rotary power source 220 should be coordinated with the frequency of gas provided by the high-pressure gas source 310. That is, the high-pressure gas source 310 only provides gas when the component is located on the workbench 100.

[0032] During use, multiple components are first placed in sequence in the distribution tray 210. Under the action of gravity, the lowest component is located on the disk surface of the distribution tray 210. When the distribution tray 210 rotates, the component will fall into the gap 211. Then, as the distribution tray 210 continues to rotate, the component is pushed above the through hole 110. When the threaded hole of the component is aligned with the through hole 110, the rotary power source 220 is suspended, the distribution tray 210 stops rotating, and then the high-pressure air source 310 blows air into the threaded hole through the nozzle 320. After the blowing is completed, the rotary power source 220 drives the distribution tray 210 to rotate again until the component falls into the discharge hole.

[0033] As a preferred embodiment, a lifting device 400 is further included. The lifting device 400 is connected to the nozzle 320 and is used to drive the nozzle 320 to vertically descend close to the threaded hole on the component on the workbench 100 when blowing air.

[0034] It should be noted that, in specific implementation, the lifting device 400 should be electrically connected to the rotary power source 220 and the high-pressure gas source 310 so that they can work in coordination with each other.

[0035] The cleaning effect can be further improved by driving the nozzle 320 down to approach the threaded hole of the component through the lifting device 400.

[0036] As a more preferred embodiment, the device further comprises an elastic blocking member 500, which is sealingly sleeved on the nozzle 320. When the nozzle 320 descends to the bottom, the blocking member 500 is pressed against the upper end surface of the component.

[0037] The blocking member 500 can seal the gas in the threaded hole to prevent the gas from overflowing, thereby further improving the cleaning effect. In addition, the elastic blocking member 500 can prevent the blocking member 500 from crushing the components.

[0038] As another preferred embodiment, the device further includes a filter device 600, which is disposed in the through hole 110 and is used to filter the air passing through the through hole 110 to prevent debris from flying around in the working chamber.

[0039] Specifically, the filter device 600 includes a connecting sleeve 610 and a filter screen 620 . The connecting sleeve 610 is detachably disposed in the through hole 110 , and the filter screen 620 is disposed on the connecting sleeve 610 and covers the through hole 110 .

[0040] The connecting sleeve 610 is detachable to facilitate cleaning of the filter 620 .

[0041] As another more preferred embodiment, the device further includes an airflow deceleration device 700 , which is disposed at the air outlet end of the through hole 110 and is used to decelerate the airflow passing through the through hole 110 .

[0042] Specifically, the airflow deceleration device 700 includes a plurality of air guide plates 710 . The air guide plates 710 are arranged in two groups opposite to each other and staggered in the through hole 110 , and each air guide plate 710 is inclined toward the outlet end of the through hole 110 .

[0043] When the gas passes through the through hole 110, it is blocked multiple times by the multiple sets of air guide plates 710, so that the high-speed gas speed can be gradually reduced.

[0044] In addition, during implementation, the device may also include a material conveyor 800. The feed end of the material conveyor 800 is located directly below the discharge port, catching components that fall from the discharge port and conveying them forward. When material falls from the discharge port onto the material conveyor 800, it is transported to the next process step via the material conveyor 800. The material conveyor 800 can utilize a conventional conveyor belt.

[0045] The above-mentioned automobile hole parts cleaning device is used as follows: When in use, the parts to be cleaned are first placed in the loading barrel 230 in sequence, and then the rotary power source 220, high-pressure gas source 310, lifting device 400 and material conveying device 800 are started to automatically complete the cleaning of the threaded holes of batches of parts.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
