Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a cleaning device for precision mechanical parts. Background Technology

[0002] In high-precision industries such as precision machinery, optical instruments, semiconductor equipment, and medical devices, the cleanliness of components directly affects product lifespan and performance. Residual particles, oil, and ionic contaminants can lead to equipment wear, signal interference, or product failure.

[0003] Traditional cleaning methods often rely on manual wiping, ultrasonic cleaning, or simple spraying, which have the following drawbacks: 1) If the cleaning water contains impurities or ions, it is easy to cause water stains or secondary pollution; 2) It is difficult to thoroughly clean the interior of complex workpieces (such as porous structures and deep cavity parts); 3) It is inconvenient to fix the workpiece and adjust the angle, which affects the uniformity of cleaning.

[0004] Based on the above, this utility model proposes a cleaning device for precision mechanical parts, which can effectively solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cleaning device for precision mechanical parts, comprising: The base is movable, and its bottom is connected to retractable casters for movement; The main cleaning chamber is mounted on one side of the top of the movable base, and it has two cleaning chambers inside. A water production and circulation system, installed on the other side of the top of the movable base, is used to draw tap water and produce ultrapure water; The water production and circulation system includes: Raw water tank, used to store tap water to be treated; Pretreatment filters, which include multi-media filters and activated carbon filters, are used to remove silt, residual chlorine and organic matter from water; The reverse osmosis unit, which includes an industrial-grade RO membrane and an EDI module, is used to produce ultrapure water with a resistivity as high as - MΩ·cm; Pure water storage tank, used for preparing ultrapure water; The water production and circulation system also includes a variable frequency constant pressure pump and a spray flushing pipe. The input end of the variable frequency constant pressure pump is connected to a pure water storage tank, and the output end of the variable frequency constant pressure pump passes through the main body of the cleaning chamber and the spray flushing pipe to supply water to the cleaning chamber. Cleaning fixtures are installed inside the main body of the cleaning chamber to secure the workpiece to be cleaned. The hole cleaning mechanism is located in the main body of the cleaning chamber and is used to clean the holes of the workpiece to be cleaned.

[0007] This utility model's cleaning device for precision mechanical parts employs a multi-stage purification process of "pretreatment + RO + EDI" to ensure ultra-high purity of the cleaning water, with a resistivity reaching - MΩ·cm. This fundamentally eliminates secondary contamination of the precision parts' surface by ions, microorganisms, and organic matter in the water, making it particularly suitable for electronic and medical components with extremely high cleanliness requirements. The variable frequency constant pressure pump provides stable and adjustable spray pressure, ensuring sufficient impact force to remove stubborn dirt while avoiding damage to the precision parts' surface from excessive pressure. The constant pressure water supply ensures uniformity and consistency of the cleaning effect. The electric push rod combined with the finger clamp structure automates the clamping action, providing stable and controllable clamping force, avoiding the uncertainties of manual operation. This structure is simple and reliable, suitable for workpieces of various standard shapes; angle The angle adjustment frame enables automatic adjustment of the workpiece's posture during the cleaning process. Through multi-angle flipping, it ensures that every surface of the component, including complex downward-facing surfaces, receives effective spraying and mechanical cleaning, greatly improving the cleaning coverage and thoroughness.

The electric push rod provides precise feed depth and stable axial pressure, while the drive motor provides efficient rotational cleaning force. The two work together to solve the problem that traditional cleaning methods cannot reach the inside of holes. The brush head can also be disassembled and replaced for different holes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: like Figure 1-5 As shown, this embodiment of the present invention provides a cleaning device for precision mechanical parts, comprising: The movable base 1 moves by means of retractable casters at its bottom. The design of the movable base 1 makes the device highly flexible and adaptable to different production lines or work sites. The main body 2 of the cleaning chamber is installed on one side of the top of the movable base 1, and has two cleaning chambers 21 inside; Water production and circulation system 3 is installed on the other side of the top of the movable base 1, and is used to draw tap water and produce ultrapure water; Water production and circulation system 3 includes: Raw water tank 31 is used to store tap water to be treated; The pretreatment filter 32 includes a multi-media filter and an activated carbon filter for removing silt, residual chlorine and organic matter from the water; The reverse osmosis unit 33 includes an industrial-grade RO membrane + EDI module for producing ultrapure water with a resistivity as high as 15-18 MΩ·cm. Pure water storage tank 34, used for preparing ultrapure water; The water production and circulation system 3 also includes a variable frequency constant pressure pump 35 and a spray flushing pipe 36. The input end of the variable frequency constant pressure pump 35 is connected to the pure water storage tank 34, and the output end of the variable frequency constant pressure pump 35 passes through the main body of the cleaning chamber 2 and the spray flushing pipe 36 to supply water to the cleaning chamber. Cleaning fixture 4 is installed inside the main body 2 of the cleaning chamber to fix the workpiece to be cleaned; Hole cleaning mechanism 5 is installed in the main body 2 of the cleaning chamber and is used to clean the holes of the workpiece to be cleaned.

[0022] Because the cleaning device for precision mechanical parts of this invention has the above structure, the multi-stage purification process of "pretreatment + RO + EDI" ensures the ultra-high purity of the cleaning water, with a resistivity of 15-18 MΩ·cm. This fundamentally eliminates secondary contamination of the precision parts surface by ions, microorganisms, and organic matter in the water, making it especially suitable for electronic and medical parts with extremely high cleanliness requirements. The variable frequency constant pressure pump 35 provides a stable and adjustable spray pressure, ensuring sufficient impact force to remove stubborn dirt while avoiding damage to the precision parts surface due to excessive pressure. The constant pressure water supply ensures the uniformity and consistency of the cleaning effect. The structure of the electric push rod 41 and the finger clamp 42 realizes the automation of the clamping action, with stable and controllable clamping force, avoiding the uncertainty of manual operation. This structure is simple and reliable, and suitable for workpieces of various standard shapes. Angle adjustment The frame 44 enables automatic adjustment of the workpiece's posture during the cleaning process. Through multi-angle flipping, it ensures that every surface of the component, including complex downward surfaces, can be effectively sprayed and mechanically cleaned, greatly improving the cleaning coverage and thoroughness. The hole cleaning mechanism 5 enables automated and high-precision mechanical cleaning of deep holes and blind holes. The electric push rod 53 provides precise feed depth and stable axial pressure, while the drive motor 51 provides efficient rotational cleaning force. The two work together to solve the problem that traditional cleaning methods cannot reach the inside of holes. The brush head 52 can also be disassembled and replaced for different holes.

[0023] Furthermore, in another embodiment, the water production and circulation system 3 also includes a delivery pump 37, which is respectively disposed between the raw water tank 31, the pretreatment filter 32, the reverse osmosis unit 33 and the pure water storage tank 34.

[0024] The front of the cleaning chamber body 2 is connected to a door, and the bottom is connected to a drain pipe with a solenoid valve, which is used to discharge the cleaning wastewater inside the cleaning chamber body 2.

[0025] Because the cleaning device for precision mechanical parts of this invention has the above structure, tap water is first pumped into the raw water tank 31 for storage, and then sent to the pretreatment filter 32 by the transfer pump 37. It then passes through a multi-media filter to remove suspended particles and activated carbon filter to adsorb residual chlorine and organic matter. The pretreated water enters the reverse osmosis unit 33, where most dissolved salts are removed by the RO membrane, and then undergoes deep desalination by the EDI module to finally obtain high-purity ultrapure water, which is stored in the pure water storage tank 34 for later use. When the cleaning process requires spraying, the control system starts the variable frequency constant pressure pump 35, which draws ultrapure water from the pure water storage tank 34, pressurizes it, and delivers it through pipelines to the spray rinsing pipe 36 inside the cleaning chamber body 2. The spray rinsing pipe 36 has multiple nozzles, enabling comprehensive and thorough rinsing of the parts. The variable frequency function automatically adjusts the water pressure and flow rate according to the cleaning stage, such as coarse cleaning or fine cleaning.

[0026] Furthermore, in another embodiment, the cleaning fixture 4 includes an electric push rod 41, the output end of which is fixedly connected to a finger clamp 42 for holding the workpiece.

[0027] The cleaning equipment 4 also includes a shaft column 45 set on the inner wall of the cleaning chamber body 2. A support frame 46 is rotatably connected to the inner side wall of the shaft column 45. An electric push rod 43 is hinged to the side wall of the shaft column 45. An angle adjustment frame 44 is slidably connected to the output end of the electric push rod 43. The angle adjustment frame 44 is fixedly engaged with the support shaft of the support frame 46.

[0028] Because the cleaning device for precision mechanical parts of this utility model has the above structure, for complex or irregularly shaped parts, using this tooling, the workpiece is first clamped by the finger clamp 42 for loading, and then the electric push rod 41 extends and retracts to push the finger clamp to the cleaning area. The control system drives the electric push rod 43 to extend and retract, pushing the angle adjustment frame 44 to swing around the rotation axis of the support frame 42, thereby driving the support frame 42 and the parts fixed on it to tilt and rotate at multiple angles to cooperate with spraying and hole cleaning.

[0029] Furthermore, in another embodiment, the hole cleaning mechanism 5 includes a drive motor 51, the output end of which is detachably connected to a brush head 52; the hole cleaning mechanism 5 also includes an electric push rod 53 fixedly connected to the inner wall of the cleaning chamber body 2, the electric push rod 53 being used to drive the brush head 52 to extend into the hole of the workpiece.

[0030] The output end of the drive motor 51 is fixedly connected to a clip 54. The clip 54 and the brush head 52 are connected by a plug-in snap-fit ​​method. The side wall of the clip 54 has two plastic elastic teeth, and the side wall of the brush head 52 has a slot that matches the plastic elastic teeth.

[0031] Because the cleaning device for precision mechanical parts of this utility model has the above structure, when it is necessary to clean the holes of the parts, the control system first drives the electric push rod 53 to extend according to the hole position, and precisely pushes the drive motor 51 with the brush head 52 to the hole entrance. Then the drive motor 51 starts, driving the brush head 52 to rotate at high speed to scrub the hole wall. After cleaning is completed, the electric push rod 53 retracts, the mechanism resets, and during installation, the connecting end of the brush head 52 is aligned with the locking head 54 and pushed in forcefully. The plastic elastic teeth retract inward under the pushing force and slide over the inner wall of the brush head 52. When the elastic teeth slide into the locking groove, their elasticity is restored, and they automatically lock, completing the connection. During disassembly, pressing the elastic teeth forcefully will disengage them from the locking groove, and the brush head 52 can be pulled out. The elastic teeth will then regain their elasticity and open again.

Therefore, the terms used to describe orientation or positional relationships in this utility model are for illustrative purposes only and should not be construed as limiting this patent.
