Description

Technical Field

[0001] This invention relates to the field of workpiece cleaning technology, and more particularly to a negative pressure vacuum cleaning and dehydration device for blind holes in workpieces. Background Technology

[0002] Impregnation, also known as immersion or penetration, is a microporous permeation sealing process. It involves introducing a sealing medium into micropores through methods such as natural permeation, vacuuming, and pressurization, filling the gaps. The sealing medium is then fixed in the gaps by natural cooling or heating, achieving a seal. Impregnation technology is an effective measure to solve casting leakage. After impregnation, to prevent the impregnating agent from remaining and solidifying in critical areas such as threaded holes and blind holes, thus affecting quality, and to save on expensive impregnating agents, a cleaning and descaling process is required.

[0003] Existing technologies also include some cleaning / dehydration devices for impregnated workpieces. For example, Chinese invention patent application number 202023182444.1, entitled "A Vacuum Impregnation Centrifugal Dehydration Device," can also dehydrate impregnated workpieces and remove residual waste liquid. However, it dehydrates by centrifugal rotation, which cannot effectively remove impregnated adhesive from small blind holes and threaded holes on the workpiece. Cleaning and dehydration are inconvenient and incomplete, especially for blind holes with a diameter less than 3mm. The quality of cleaning and dehydration is low, failing to effectively guarantee the normal use of the workpiece later and easily leading to low product quality. Another example is Chinese invention patent application number 201922123020.9, entitled "A Vacuum Impregnation Centrifugal Dehydration Device," which also suffers from the above problems.

Figure 1As shown, it includes a cleaning tank assembly 1, a base 2, a drain overflow pipeline assembly 3, a vacuum and piping system 4, and a cleaning tank cover assembly 5. The cleaning tank assembly 1 is used to hold the impregnated workpiece. Large impregnated workpieces can be placed directly inside the cleaning tank assembly 1. For small workpieces, they are usually placed in a workpiece basket and then placed entirely inside the cleaning tank assembly 1 for cleaning. The drain overflow pipeline assembly 3 is positioned lower than the cleaning tank assembly 1 and is used to drain impregnation waste liquid and waste adhesive particles from the cleaning tank assembly 1. The vacuum and piping system 4 is used to create a vacuum inside the cleaning tank assembly 1, allowing residual adhesive and liquid to drain from blind holes in the impregnated workpiece. This solves the problem of incomplete cleaning of impregnated adhesive in small blind holes and threaded holes on the workpiece, especially for blind holes with a diameter less than 3mm, which are difficult to clean thoroughly using existing centrifugal dehydration and manual cleaning methods, thereby improving the impregnation quality of the workpiece. The cleaning tank lid assembly 5 is movable and seals onto the top of the cleaning tank assembly 1. During negative pressure cleaning, the cleaning tank lid assembly 5 seals onto the top of the cleaning tank assembly 1. When loading or unloading workpieces, the cleaning tank lid assembly 5 can be moved open. The cleaning tank assembly 1, the drain overflow pipeline assembly 3, and the vacuum and pipeline system 4 are all fixedly installed on the upper end of the base 2, making the entire blind hole negative pressure vacuum cleaning and dehydration device for impregnated workpieces a whole, which is convenient for handling and fixed installation.

[0034] The present invention provides a negative pressure vacuum cleaning and dehydration device for blind holes in impregnated workpieces, the working process of which is as follows:

[0035] (1) The placement method for workpiece immersion and cleaning is selected according to the size and other factors of the workpiece. For large workpieces, they are placed directly in the cleaning tank assembly 1. For small workpieces, they are placed in the workpiece basket and then placed in the cleaning tank assembly 1 for cleaning. In this embodiment, the workpiece to be immersed is a small workpiece, which is placed in the workpiece basket for immersion and cleaning. The workpiece basket uses the workpiece immersion basket in the prior art. There are many disclosures on the structure and use of workpiece immersion baskets in the prior art. In this embodiment, the structure and use of workpiece immersion baskets will not be described in detail.

[0036] (2) Place the workpiece to be cleaned and the workpiece soaking basket containing it into the cleaning tank assembly 1, and move the cleaning tank cover assembly 5 to seal and close the top of the cleaning tank.

[0037] (3) Start the vacuum and pipeline system 4 to evacuate the cleaning tank assembly 1. Under the vacuum environment, the residual impregnating adhesive inside the blind hole of the workpiece is sucked out by the cleaning tank assembly 1.

[0038] (4) After the above work is completed, restore the air pressure in the cleaning tank assembly 1 to normal, and then start the drainage overflow pipeline assembly 3 to absorb and discharge the impregnating adhesive and solution in the cleaning tank assembly 1.

[0039] (5) Finally, remove the cleaning tank cover assembly 5 and take out the workpiece.

[0040] This invention provides a negative pressure vacuum cleaning and descaling device for blind holes in impregnated workpieces. It utilizes negative pressure technology to clean residual adhesive from the blind holes of impregnated workpieces, solving the problems of inconvenient and incomplete cleaning of impregnated adhesive in small blind holes and threaded holes in existing technologies. This is particularly effective for blind holes with a diameter less than 3mm, where existing centrifugal descaling and manual cleaning methods are difficult to use thoroughly. The device achieves high-efficiency and high-quality cleaning of residual adhesive from blind holes in workpieces, thereby improving workpiece quality and ensuring its future use.

[0041] This embodiment describes a negative pressure vacuum cleaning and dehydration device for blind holes in impregnated workpieces, referring to... Figure 2 , Figure 3 As shown, the cleaning tank assembly 1 specifically includes a cleaning tank body support 11, an RF admittance level gauge 110, a cleaning tank body 111, a sealing ring 112, a bottom pipe 113, an upper pipe 114, and a moving mechanism.

There are two guide rail support plates 117, symmetrically arranged on the front and rear sides of the cleaning tank body 111; there are two standard guide rails 16, which are horizontally fixed to the top of the guide rail support plate 117; and one cylinder support plate 115 is fixed to the guide rail support plate. The outer side of plate 117; the drag chain groove 116 is set on the side of cylinder support plate 115; the rodless cylinder 13 is fixed on the upper end of cylinder support plate 115. In this embodiment, the rodless cylinder 13 uses the mechanical rodless cylinder in the prior art.

[0043] One end of the standard cable chain 12 is located in the cable chain groove 116. The standard cable chain 12 is used to drag the air supply pipeline (not shown in the figure) used by the rodless cylinder 13 and the cleaning tank lid assembly 5, so that the pipeline moves together with the drive end of the rodless cylinder 13, so that the built-in air supply pipeline can be pulled and protected during reciprocating movement. Four limiting members 17 are symmetrically fixed on both sides of the two standard guide rails 16 to limit the cleaning tank lid assembly 5 and prevent it from moving excessively. The solenoid valve assembly 14 is fixed on the cleaning tank body support 11. In this embodiment, the solenoid valve assembly 14 uses the existing cartridge solenoid valve to control the flow direction, flow rate and pressure of the gas in the air supply pipeline, thereby controlling the action of the rodless cylinder 13 and the lifting cylinder.

[0044] This embodiment describes a negative pressure vacuum cleaning and dehydration device for blind holes in impregnated workpieces, referring to... Figure 6 As shown, the drainage overflow pipeline assembly 3 specifically includes a manual drain valve 31, an overflow pump bracket 33, an overflow solenoid valve 34, an overflow diaphragm pump 35, and a three-way pipe 36. The first end of the three-way pipe 36 is connected to the bottom pipe 113. The manual drain valve 31 is installed on the second end of the three-way pipe 36 for direct drainage. The overflow diaphragm pump 35 is connected to the second end of the three-way pipe 36 via a pipe, which is also equipped with an overflow pneumatic ball valve 32 for controlling the opening and closing of this section of the pipe. The bottom end of the overflow pump bracket 33 is fixed to the upper end of the base 2. The overflow diaphragm pump 35 and the overflow solenoid valve 34 are both fixed on the overflow pump bracket 33. The overflow solenoid valve 34 is used to control the operation of the overflow diaphragm pump 35. The drainage overflow pipeline assembly 3 can discharge the impregnated waste liquid and waste adhesive particles in the cleaning tank 111 through the overflow diaphragm pump 35.

[0045] This embodiment describes a negative pressure vacuum cleaning and dehydration device for blind holes in impregnated workpieces, referring to... Figure 7As shown, the cleaning tank lid assembly 5 includes a lifting frame 51, a translation frame 52, a translation cylinder connecting frame 53, a lifting cylinder 54, a slider 55, an upper cover 56, and rollers 57.

Driven by the lifting cylinders 54, the lifting frame 51 can move vertically up and down within a certain height range above the translation frame 52. Several connecting rods 511 are fixed to the top of the upper cover 56. The connecting rod 511 is connected to the bottom end of the lifting frame 51 via the connecting seat 510, so that the top cover 56 can move vertically up and down within a certain height range below the translation frame 52, for sealing and closing the top of the cleaning tank body 111; a slider 55 is fixed to the bottom end of the support leg on one side of the translation frame 52, and the slider 55 is slidably mounted on a standard guide rail 16; a roller 57 is fixed to the bottom end of the support leg on the other side of the translation frame 52, and the roller 57 is located on another standard guide rail 16; the translation cylinder connecting frame 53 is connected to the actuating end of the rodless cylinder 13.

[0046] Furthermore, the cleaning tank lid assembly 5 also includes four linear bearings 58 and a guide shaft 59 vertically installed in the linear bearings 58. The linear bearings 58 are fixed to the top of the translation frame 52, and the top of the guide shaft 59 is fixed to the bottom of the lifting frame 51, so that the vertical lifting movement between the lifting frame 51 and the translation frame 52 is more stable.

[0047] The drive end of the rodless cylinder 13 is connected to the translation frame 52 through the translation cylinder connecting frame 53, driving the translation frame 52 to move. One side of the translation frame 52 slides on the standard guide rail 16 through the slider 55, and the other side rolls on another standard guide rail 16 through the roller 57, so that the translation frame 52 can move horizontally on the left and right sides of the cleaning tank body 111.

[0048] When using the cleaning tank lid assembly 5, the rodless cylinder 13 drives the translation frame 52 to move directly above the cleaning tank body 111. Driven by the lifting cylinder 54, the lifting frame 51 descends vertically above the translation frame 52, causing the upper cover 56 to seal onto the cleaning tank body 111. During the movement of the upper cover 56, the linear bearing 58 and guide shaft 59 between the lifting frame 51 and the translation frame 52 cooperate to improve the smoothness of the lifting and lowering movement between them.

Automatic water replenishment valve 411 is installed at the upper part of cooling water tank 410, and automatic water replenishment valve 411 is connected to external water supply pipe for replenishing water to cooling water tank 410.

[0050] When vacuuming the cleaning tank 111, the atmospheric valve 46 is closed and the vacuum valve 44 is opened, and the water-circulating vacuum pump 42 operates to evacuate the tank. After vacuuming is complete, the water-circulating vacuum pump 42 stops operating. When venting the vacuum, the vacuum valve 44 is closed and the atmospheric valve 46 is opened, and the air is vented from the cleaning tank 111 through the silencer 47. Throughout the entire process, the electronic pressure gauge 45 is used to collect the vacuum signal in the pipeline, and the mechanical pressure gauge 43 is used for manual observation to facilitate timely understanding of the pressure in the pipeline. The vacuum and piping system 4 uses the water-circulating vacuum pump 42 to evacuate the cleaning tank 111. During this process, the chiller 41 draws cold water from the cooling water tank 410 to cool the water-circulating vacuum pump 42. Under the vacuum environment, the residual impregnating adhesive inside the blind holes of the workpiece in the cleaning tank 111 is sucked out.
