Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts cleaning technology, specifically relating to a high-efficiency ultrasonic cleaning mechanism for lead screws. Background Technology

[0002] As an important component in mechanical transmission, lead screws are also commonly used in the automotive industry, such as seat adjustment lead screws. They generally include a threaded transmission part that connects to the actuator and a connecting head end with a diameter larger than the threaded part that connects to the drive part.

[0003] In mass production, the cleanliness of the lead screw surface directly affects the operating accuracy and lifespan of mechanical equipment. Traditional cleaning methods often employ chemical cleaning or manual brushing, which are not only inefficient but also prone to damaging the lead screw surface. Ultrasonic cleaning technology, due to its high efficiency and non-destructive characteristics, has gradually become the mainstream method for industrial cleaning. However, existing ultrasonic cleaning equipment often suffers from uneven cleaning and difficulty in cleaning hard-to-reach areas when cleaning lead screws. Utility Model Content

[0004] This invention provides a high-efficiency ultrasonic cleaning mechanism for lead screws. During liquid addition, the sprayed cleaning fluid can pre-rinse the lead screw. Once the liquid has submerged the outer frame and the mounting rack, the ultrasonic generator is activated to begin ultrasonic cleaning. During the cleaning process, the high-frequency vibration generated by the ultrasonic generator causes the cleaning fluid to produce a cavitation effect, effectively removing dirt from the surface of the lead screw, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency lead screw ultrasonic cleaning mechanism, comprising...

[0006] A cleaning chamber, wherein a cleaning tank is provided inside the cleaning chamber and a lid that can be opened and closed to seal the cleaning tank is installed on the top;

[0007] An ultrasonic generator, which is mounted on one side of the cleaning chamber;

[0008] A support platform is located inside the cleaning tank and protrudes upward to a certain height. There are gaps between the support platform and the four inner walls of the cleaning tank.

[0009] The outer frame is fixed to the top of the support platform;

[0010] A placement rack, which is installed inside the outer frame;

[0011] The liquid filling mechanism includes multiple liquid filling pipes located inside the cleaning tank, with one end of each liquid filling pipe connected to the outside of the cleaning chamber.

[0012] Preferably, the bottom of the cleaning tank is equipped with a drain pipe, and the drain pipe is equipped with a valve.

[0013] Preferably, the liquid filling pipe is provided with a plurality of nozzles facing the outer frame.

[0014] Preferably, the outer frame is a square frame welded together from multiple metal rods.

[0015] Preferably, the placement rack includes a square frame welded from multiple metal rods and placement mesh welded to the top and bottom of the square frame. The square frame forms a placement space between the upper and lower placement meshes, and the placement meshes form multiple placement grids.

[0016] Preferably, the placement mesh includes multiple longitudinal and transverse metal strips, and the metal strips are made of high-hardness alloy material.

[0017] Preferably, the metal strips are all wavy in the height direction, and the longitudinal metal strips and the transverse metal strips are welded at the troughs and form support positions at the crests.

[0018] Preferably, the placement rack has handles welded on both sides.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. When adding liquid, the sprayed cleaning liquid can be used to pre-rinse the lead screw. When the liquid covers the outer frame and the placement rack, start the ultrasonic generator to begin ultrasonic cleaning. During the cleaning process, the high-frequency vibration generated by the ultrasonic generator causes the cleaning liquid to produce a cavitation effect, effectively removing dirt from the surface of the lead screw.

[0021] 2. After the lead screw is inserted, the larger diameter connecting end of the upper part of the lead screw presses on the support position formed by the longitudinal and transverse metal strips. This is a point contact with a small contact area, which is conducive to thorough cleaning.

[0022] 3. By placing a grid, a large number of lead screws can be cleaned efficiently at once. At the same time, the grid between the upper and lower layers of vertical and horizontal metal strips limits the position of the lead screws during the cleaning process. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-4 This utility model provides a high-efficiency ultrasonic cleaning mechanism for lead screws, including a cleaning chamber 1, a cleaning tank 2 inside the cleaning chamber 1, and a slewable, sealable cover 3 on the top; an ultrasonic generator 4, mounted on one side of the cleaning chamber 1; a support platform 5, located inside the cleaning tank 2 and protruding upwards to a certain height, with gaps between the support platform 5 and the four inner walls of the cleaning chamber 1; an outer frame 6, fixed to the top of the support platform 5; and a placement rack 7. The placement rack 7 is installed inside the outer frame 6; the liquid filling mechanism includes multiple liquid filling pipes 8 located in the cleaning tank 2, one end of each liquid filling pipe 8 being connected to the outside of the cleaning chamber 1; in use, multiple lead screws are fixed on the placement rack 7, the frequency and power of the ultrasonic generator 4 are adjusted, and the liquid filling mechanism is started to add liquid. When the liquid has submerged the outer frame 6 and the placement rack 7, the ultrasonic generator 4 is started to begin ultrasonic cleaning; during the cleaning process, the high-frequency vibration generated by the ultrasonic generator 4 causes the cleaning liquid to produce a cavitation effect, effectively removing dirt from the surface of the lead screws.

[0030] Specifically, the bottom of the cleaning tank 1 is equipped with a drain pipe 9, and a valve is installed on the drain pipe 9; in this embodiment, the waste liquid after cleaning is discharged from the drain pipe 9 and continuously recycled after filtering impurities.

[0031] Specifically, the liquid filling pipe 8 is provided with a plurality of nozzles 10 facing the outer frame 6; in this embodiment, the external liquid supply device connected to the liquid filling pipe 8 is activated, and the cleaning liquid is sprayed into the cleaning tank 2 through the nozzles 10. When adding liquid, the sprayed cleaning liquid can be used to pre-rinse the lead screw, further improving the cleaning efficiency and effect.

[0032] Specifically, the outer frame 6 is a square frame welded from multiple metal rods. In this embodiment, by setting the outer frame 6, the subsequent placement rack 7 can be positioned in a limited manner to prevent it from tilting or swaying. At the same time, the placement rack 7 is raised to a certain height so that after the screw is placed, the screw does not contact the bottom support platform 5, thus achieving suspended placement and further improving the cleaning effect.

[0033] Specifically, the placement rack 7 includes a square frame 11 welded from multiple metal rods and placement nets 12 welded to the top and bottom of the square frame 11. The square frame 11 forms a placement space between the upper and lower placement nets 12, and the placement nets 12 form multiple placement grids 13. In this embodiment, the height of the two layers of placement nets 12 is designed according to the height of the lead screw to be cleaned, so that after the lead screw is inserted, the connecting end with a larger diameter at the top of the lead screw presses on the placement grids 13. Through the placement grids 13, a large number of lead screws can be cleaned efficiently at one time. At the same time, the placement grids of the upper and lower layers of placement nets 12 limit the placement of the lead screws and maintain stable placement during the cleaning process.

[0034] Specifically, the placement net 12 includes multiple longitudinal and transverse metal strips 14 and transverse metal strips 15, and the metal strips are made of high-hardness alloy material; in this embodiment, the metal strips are less prone to deformation and are more stable after a large number of lead screws are placed on them.

[0035] Specifically, the metal strips are all wavy in the height direction. The longitudinal metal strip 14 and the transverse metal strip 15 are welded at the troughs and form a support position at the crest. In this embodiment, when the connecting end with a larger diameter at the top of the lead screw is pressed against the support position formed by the longitudinal metal strip 14 and the transverse metal strip 15 after the lead screw is inserted, it is in point contact with a small contact area, which is conducive to thorough cleaning.

[0036] Specifically, the placement rack 7 has handles 16 welded on both sides; in this embodiment, it is convenient to place and retrieve the placement rack 7 inside the outer frame 6 by means of the handles 16.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] Working principle: During use, multiple lead screws are fixed on the placement frame 7. The frequency and power of the ultrasonic generator 4 are adjusted, and the external liquid supply device connected to the liquid supply pipe 8 is started. The cleaning solution is sprayed into the cleaning tank 2 through the nozzle 10. During liquid addition, the sprayed cleaning solution can pre-rinse the lead screws. When the liquid has submerged the outer frame 6 and the placement frame 7, the ultrasonic generator 4 is started to begin ultrasonic cleaning. During the cleaning process, the high-frequency vibration generated by the ultrasonic generator 4 causes cavitation effect in the cleaning solution, effectively removing dirt from the surface of the lead screws. The waste liquid after cleaning is discharged from the drain pipe 9. After filtering impurities, it is continuously recycled. During this process, the height of the two layers of placement mesh 12 is designed according to the height of the lead screw to be cleaned, so that after the lead screw is inserted, the larger diameter connecting end of the lead screw presses on the support position formed by the longitudinal metal strip 14 and the transverse metal strip 15, while the bottom end of the lead screw is limited by the placement mesh 13 between the lower longitudinal metal strip 14 and the transverse metal strip 15. This allows for efficient batch cleaning of a large number of lead screws at once. At the same time, when the lead screw presses on the support position of the longitudinal metal strip 14 and the transverse metal strip 15 at the connecting end, it is in point contact with a small contact area, which is conducive to thorough cleaning.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
