Description

Technical Field

[0001] The present invention relates to a highly adaptable pulley anti-rust oil coating device and a use method thereof, which can effectively and evenly coat the anti-rust oil on the bearing mounting hole wall of the pulley workpiece without causing scratches on the bearing mounting hole wall of the pulley workpiece. Background Art

[0002] In conventional pulleys, after a critical process such as fine turning of the bearing mounting hole diameter, it is necessary to apply anti-rust oil to the bearing mounting hole wall of the workpiece.

[0003] Currently, applying anti-rust oil to the bearing mounting hole of a pulley is primarily done manually using a brush or a smear cloth to apply the oil. This method requires manual control of the amount of anti-rust oil applied by the brush, relying solely on feel, and ensuring consistent application. Applying a large amount of anti-rust oil wastes resources and can cause the workpiece to slide downward under gravity after it has been allowed to rest for a period of time, leaving water marks on unapplied areas of the workpiece or on the product packaging, significantly impacting the appearance. Applying a small amount directly impacts the anti-rust effect, leading to rust and potentially substandard products. A major issue is that the bearing mounting hole of the pulley is often clinging to tiny swarf after machining. This can easily cause scratches on the wall during the application of the anti-rust oil.

[0004] Therefore, the research purpose of the present invention is to design a highly adaptable pulley anti-rust oil coating device and its use method that can effectively, quickly and evenly apply anti-rust oil to the bearing mounting hole wall of the pulley, and can effectively prevent the problem of scratches on the bearing mounting hole wall of the pulley caused by the application of anti-rust oil.

[0018] The upper surface of the product tray is concavely provided with a corresponding workpiece embedding groove, in which a sheet-shaped magnet is fixedly connected, and the upper part of the magnet is covered with a corresponding flexible rubber pad.

[0019] The upper surface of the product tray is concavely provided with a corresponding workpiece embedding groove, and the workpiece limiting mechanism includes a magnet sheet arranged in the workpiece embedding groove, and the upper part of the magnet sheet is covered and connected with a layer of corresponding flexible rubber pad.

[0020] The thickness of the flexible rubber pad is set within 2mm, and a plurality of iron chip receiving holes arranged in a truncated cone shape are evenly arranged on the upper surface of the flexible rubber pad downward.

[0021] The bottom side of the raised portion of the spring limit block is spherical, and a corresponding trigger switch is fixedly connected to the rear side of the raised portion of the spring limit block. The trigger switch is electrically connected to the electric controller.

[0022] A method for using a highly adaptable pulley anti-rust oil coating device includes the following specific steps:

[0023] S1, manually or by robot loading, fix the workpiece into the workpiece embedding slot of the product tray;

[0024] S2, the first solenoid valve is opened for a time period t1, and a small amount of rust-proof oil is added to the rust-proof oil adsorption rod;

[0025] S3, the push-pull electromagnet is energized, driving the spring sheet upward, and the raised portion of the spring sheet limit block limits the smearing portion of the spring sheet, causing the smearing portion of the spring sheet to fold inward through a certain angle and trigger the trigger switch;

[0026] S4, the lifting motor is started to drive the winding wheel to rotate forward, the wire rope wound on the winding wheel is output, the mounting bracket moves downward, and the smearing portion of the inwardly folded spring sheet and the fixing plate equipped with the chip blowing pipe extend into the bearing mounting hole of the workpiece;

[0027] S5, the rotary motor is started, driving the workpiece to rotate one circle. At the same time, the second solenoid valve is opened, and high-pressure gas is blown through the chip blowing pipe to the bearing mounting hole wall of the workpiece, so that the chips attached to the bearing mounting hole wall are blown away from the bearing mounting hole wall and are attracted by the sheet-shaped magnetic attraction plate;

[0028] S6, the second solenoid valve is closed, the push-pull electromagnet is powered off, and the spring sheet is reset downward, so that the coating portion of the spring sheet is folded outward and pressed against the wall of the bearing mounting hole of the workpiece, and the rotating motor drives the workpiece to rotate one circle again and then stops, and the anti-rust oil adsorption rod effectively applies the anti-rust oil to the wall of the bearing mounting hole of the workpiece;

[0029] S7, the push-pull electromagnet is energized, driving the spring sheet upward, and the protrusion of the spring sheet limit block again limits the smearing portion of the spring sheet, causing the smearing portion of the spring sheet to fold inward again through a certain angle and trigger the trigger switch;

[0030] S8, the lifting motor is started to drive the winding wheel to rotate in the opposite direction, the wire rope is wound on the winding wheel, and the mounting bracket is reset upward;

[0031] S9, remove the workpiece coated with anti-rust oil manually or by a robot and place it on the corresponding workpiece collection mechanism.

[0032] In step S5, the chips that are not attracted by the sheet-shaped magnetic plate fall to the upper surface of the flexible rubber pad. As the air flow stirs, the chips move on the upper surface of the flexible rubber pad. When they pass through the iron chip receiving hole, they are attracted by the magnet sheet into the iron chip receiving hole.

[0033] Advantages of the present invention:

[0034] 1) The smearing mechanism of the present invention comprises a mounting bracket that is liftably mounted above the workpiece stop mechanism. A spring is liftably mounted on the mounting bracket. The spring comprises a mounting portion and an smearing portion that is tilted outward from the mounting portion. A rust-proof oil adsorption rod is fixedly connected to one side of the smearing portion. Furthermore, the present invention includes a spring stopper, the top of which is fixedly attached to the mounting bracket. A protrusion is positioned downwardly at the bottom of the spring stopper to abut and limit the position of the smearing portion where the rust-proof oil adsorption rod is not connected.

[0035] During the working process: first, the spring sheet moves upward, so that the raised part of the spring sheet limit block forms a limit on the smearing part, so as to drive the smearing part to fold inward through a certain angle, so that the smearing part of the inwardly folded spring sheet can extend into the bearing mounting hole of the workpiece as the mounting bracket moves downward; then, the spring sheet returns downward, so that the smearing part of the spring sheet can be pressed outward against the wall of the bearing mounting hole of the workpiece. Through the rotation of the workpiece, the anti-rust oil can be effectively and evenly applied to the wall of the bearing mounting hole of the workpiece.

[0036] 2) The mounting portion of the present invention, not provided with an applicator, has a downwardly fixed plate at one end. A chip blowing tube is affixed outwardly to the center of the fixed plate. Sheet-shaped magnetic plates are fixed to the fixed plates on either side of the chip blowing tube. The outer sides of the sheet-shaped magnetic plates are folded inward in an L-shape. Before applying the anti-rust oil, the second solenoid valve is opened to allow high-pressure gas to blow through the chip blowing tube and onto the bearing mounting hole wall of the workpiece. Simultaneously, the workpiece rotates one revolution, causing chips adhering to the bearing mounting hole wall to be blown away from the bearing mounting hole wall and attracted to the sheet-shaped magnetic plate, thereby effectively preventing scratches on the pulley bearing mounting hole wall caused by the application of anti-rust oil.

[0037] 3) The upper surface of the product tray of the present invention is concavely provided with a corresponding workpiece embedding groove, and a sheet-shaped magnet is fixedly connected to the workpiece embedding groove, which fixes the workpiece through magnetic attraction, thereby cooperating with the workpiece embedding groove to form a fast and stable installation of the workpiece.

[0038] On this basis, the present invention further covers the upper part of the magnet sheet with a corresponding flexible rubber pad to prevent mechanical damage to the surface of the workpiece during the magnetic attraction process, and sets the thickness of the flexible rubber pad within 2 mm to prevent the bottom of the workpiece from being excessively embedded in the flexible rubber pad, thereby preventing the problem of inadequate application of anti-rust oil.

[0039] The most important thing is that the present invention further evenly arranges a number of iron chip receiving holes in a truncated cone shape downward on the upper surface of the flexible rubber pad. When removing the chips attached to the wall of the bearing mounting hole, the chips that are not adsorbed by the sheet-shaped magnetic plate fall to the upper surface of the flexible rubber pad. As the airflow stirs, the chips move on the upper surface of the flexible rubber pad, and when they pass through the iron chip receiving holes, they are adsorbed into the iron chip receiving holes by the magnet sheets. Since the outer edges of the upper end faces of the iron chip receiving holes are respectively provided with a circle of downwardly inclined chamfers, the probability of the iron chips being adsorbed by the magnet sheets can be increased. And since the iron chip receiving holes are truncated cone-shaped, the adsorbed iron chips are not easily carried away from the iron chip receiving holes by the airflow, thereby effectively ensuring the practical effect of the present invention.

[0040] 4) The bottom side of the raised portion of the spring limit block of the present invention is spherical, and a corresponding trigger switch is fixedly connected to the rear side of the raised portion of the spring limit block. When the smearing portion of the spring sheet is folded inward through a certain angle, it can trigger the trigger switch to ensure that the smearing portion of the spring sheet can only move downward and upward under the condition that it is folded inward into place, thereby preventing interference and collision between the conveying spring sheet and the workpiece due to misoperation, thereby effectively and significantly improving the practical effect of the present invention.

[0052] a workpiece limiting mechanism 3 , provided on the upper surface of the product tray 203 , for fixing the workpiece to the upper surface of the product tray 203 ;

[0053] The smearing mechanism 4 includes a mounting bracket 401 that can be lifted and lowered on the upper side of the workpiece limiting mechanism 3. The mounting bracket 401 is lifted and lowered by a corresponding bracket driving mechanism 5. A spring piece 402 is lifted and lowered on the mounting bracket 401. The spring piece 402 is lifted and lowered by a corresponding spring driving mechanism 6.

[0054] The spring limit block 7 is fixed on the mounting bracket 401. The top of the spring limit block 7 is fixed to the mounting bracket 401. The bottom of the spring limit block 7 is provided with a protrusion for abutting and limiting the position of the smearing portion 4022 where the anti-rust oil adsorption rod 403 is not connected. When the spring 402 moves upward, the protrusion of the spring limit block 7 limits the smearing portion 4022, so as to drive the smearing portion 4022 to fold inward through a certain angle.

[0055] The electric controller 8 is used to control the working process of the bracket driving mechanism 5, the reed driving mechanism 6, and the rotating motor 202. The electric controller in this embodiment adopts a programmable PLC encoder.

[0056] During the working process: first, the spring piece 402 moves upward, so that the raised part of the spring piece limiting block 7 forms a limit on the smearing part 4022, so as to drive the smearing part 4022 to fold inward through a certain angle, so that the smearing part 4022 of the inwardly folded spring piece 402 can extend into the bearing mounting hole of the workpiece as the mounting bracket 401 moves downward; thereafter, the spring piece 402 moves downward and resets, so that the smearing part 4022 of the spring piece 402 can be pressed outward against the wall of the bearing mounting hole of the workpiece, and the anti-rust oil can be effectively and evenly applied to the wall of the bearing mounting hole of the workpiece through the rotation of the workpiece.

[0057] The top of the support column 102 is fixedly connected to a corresponding lifting motor fixing plate 9, and the bracket driving mechanism 5 includes a lifting motor 501 fixed on one side of the lifting motor fixing plate 9. The output shaft end of the lifting motor 501 is fixedly connected to a corresponding winding wheel 502, and a corresponding steel wire rope 503 is wound on the winding wheel 502. The end of the steel wire rope 503 not wound on the winding wheel 502 is fixedly connected to the mounting bracket 401, and the lifting motor 501 is electrically connected to the electric controller 8.

[0058] The spring drive mechanism 6 includes a push-pull electromagnet fixed on the mounting bracket 401 , the mounting portion of the spring 402 is fixed on the push-pull rod of the push-pull electromagnet, and the push-pull electromagnet is electrically connected to the electric controller 8 .

[0059] The anti-rust oil adsorption rod 403 is a diatomaceous earth moisture-absorbing rod, and a fixing device on the mounting bracket 401 is provided with an anti-rust oil storage tank 10. The discharge end of the anti-rust oil storage tank 10 is externally connected to a corresponding refueling pipe 12 through a corresponding first solenoid valve 11. The oil outlet end of the refueling pipe 12 abuts against the upper end of the anti-rust oil adsorption rod 403, and the first solenoid valve 11 is electrically connected to the electric controller 8.

[0060] The mounting portion 4021 is not provided with a coating portion 4022, and one end thereof is fixed downwardly with a corresponding fixing plate 13. The middle part of the fixing plate 13 is fixedly connected to a corresponding chip blowing pipe 14 outwardly. The bottom end of the chip blowing pipe 14 is closed, and the top end of the chip blowing pipe 14 is connected to an external air compressor through a corresponding pneumatic tube 1401 and a second solenoid valve 1402. A plurality of corresponding air blowing holes are provided at intervals on one side of the bearing mounting hole wall of the chip blowing pipe 14 facing the workpiece. Corresponding sheet magnetic plates 15 are fixed on the fixing plates 13 on both sides of the chip blowing pipe 14, and the outer sides of the sheet magnetic plates 15 are L-shaped and folded inward.

[0061] Before applying the anti-rust oil, the second solenoid valve 1402 is opened in advance to allow high-pressure gas to blow the bearing mounting hole wall of the workpiece through the chip blowing pipe 14. At the same time, the workpiece rotates one circle, so that the chips attached to the bearing mounting hole wall are blown away from the bearing mounting hole wall and adsorbed by the sheet-like magnetic plate 15, thereby effectively preventing the problem of scratches on the bearing mounting hole wall of the pulley caused by the application of anti-rust oil.

[0062] The upper surface of the product tray 203 is concavely provided with a corresponding workpiece mounting groove. The workpiece retaining mechanism 3 includes a magnet sheet 301 disposed within the workpiece mounting groove. The upper portion of the magnet sheet 301 is covered and connected with a corresponding flexible rubber pad 302. In this embodiment, the flexible rubber pad 302 is laid flat on the upper portion of the magnet sheet 301 and can be removed periodically to remove the iron filings adsorbed on the magnet sheet 301.

[0063] The thickness of the flexible rubber pad 302 is 1.5 mm. A plurality of truncated cone-shaped iron chip receiving holes 16 are evenly arranged downward on the upper surface of the flexible rubber pad 302 . The outer edges of the upper end surfaces of the iron chip receiving holes 16 are respectively provided with a circle of downwardly inclined chamfers 17 .

[0064] The workpiece is secured by magnetic attraction, thereby cooperating with the workpiece mounting slot to achieve fast and stable installation. Furthermore, the present invention further includes a corresponding flexible rubber pad 302 covering the upper portion of the magnet sheet 301 to prevent mechanical damage to the workpiece surface during magnetic attraction. The thickness of the flexible rubber pad is set to less than 2mm to prevent the bottom of the workpiece from being excessively embedded in the flexible rubber pad 302, thereby preventing the problem of insufficient application of anti-rust oil. The most important thing is that the present invention further evenly arranges a number of iron chip receiving holes 16 in a truncated cone shape downward on the upper surface of the flexible rubber pad 302. When removing the chips attached to the wall of the bearing mounting hole, the chips that are not adsorbed by the sheet-shaped magnetic plate 15 fall to the upper surface of the flexible rubber pad 302. As the air flow stirs, the chips move on the upper surface of the flexible rubber pad 302. When they pass through the iron chip receiving holes 16, they are adsorbed into the iron chip receiving holes 16 by the magnet sheet 301; since the outer edges of the upper end faces of the iron chip receiving holes 16 are respectively provided with a circle of downwardly inclined chamfers 17, the probability of the iron chips being adsorbed by the magnet sheet 301 can be increased; and since the iron chip receiving holes 16 are truncated cone-shaped, the adsorbed iron chips are not easily carried away from the iron chip receiving holes 16 by the air flow, thereby effectively ensuring the practical effect of the present invention.

[0065] The bottom side of the raised portion of the reed limit block 7 is spherical, and a corresponding trigger switch 18 is fixedly connected to the rear side of the raised portion of the reed limit block 7 , and the trigger switch 18 is electrically connected to the electric controller 8 .

[0066] When the smearing portion 4022 of the spring piece 402 is folded inwardly through a certain angle, it can trigger the trigger switch 18 to ensure that the smearing portion 4022 of the spring piece 402 can move downward and upward under the condition of being folded inwardly into place, thereby ensuring that the smearing portion 4022 will not touch the workpiece, and ensuring that the smearing portion 4022 of the spring piece 402 can drive the anti-rust oil adsorption rod 403 to form abutment and tighten against the inner wall of the workpiece when restoring its deformation, so as to further ensure the practical effect of the present invention.

[0067] Example 2:

[0068] The method for using the above-mentioned highly adaptable pulley anti-rust oil coating device includes the following specific steps:

[0069] S1, manually or robotically loading the workpiece into the workpiece mounting slot of the product tray 203;

[0070] S2, the first solenoid valve 11 is opened for 0.5 seconds to add a small amount of anti-rust oil to the anti-rust oil adsorption rod 403;

[0071] S3, the push-pull electromagnet is energized, driving the spring piece 402 upward, and the protrusion of the spring piece limit block 7 limits the smearing portion 4022 of the spring piece 402, causing the smearing portion 4022 of the spring piece 402 to fold inward through a certain angle and trigger the trigger switch 18;

[0072] S4, the lifting motor 501 is started to drive the winding wheel 502 to rotate forward, the wire rope 503 wound on the winding wheel 502 is output, the mounting bracket 401 moves downward, and the smearing portion 4022 of the inwardly folded spring sheet 402 and the fixing plate 13 equipped with the chip blowing pipe 14 extend into the bearing mounting hole of the workpiece;

[0073] S5: The rotating motor 202 is started, driving the workpiece to rotate one circle. At the same time, the second solenoid valve 1402 is opened, and high-pressure gas is blown through the chip blowing pipe 14 to the bearing mounting hole wall of the workpiece, so that the chips attached to the bearing mounting hole wall are blown away from the bearing mounting hole wall and attracted by the sheet-shaped magnetic attraction plate 15.

[0074] S6, the second solenoid valve 1402 is closed, the push-pull electromagnet is powered off, and the spring sheet 402 is reset downward, so that the coating portion 4022 of the spring sheet 402 is folded outward and pressed against the wall of the bearing mounting hole of the workpiece. The rotary motor 202 drives the workpiece to rotate one circle again and then stops. The anti-rust oil adsorption rod 403 effectively applies the anti-rust oil to the wall of the bearing mounting hole of the workpiece;

[0075] S7, the push-pull electromagnet is energized, driving the spring piece 402 upward, and the protrusion of the spring piece limit block 7 again limits the smearing portion 4022 of the spring piece 402, causing the smearing portion 4022 of the spring piece 402 to bend inward again through a certain angle and trigger the trigger switch 18;

[0076] S8, the lifting motor 501 is started to drive the winding wheel 502 to rotate in the opposite direction, the wire rope 503 is wound around the winding wheel 502, and the mounting bracket 401 is reset upward;

[0077] S9, remove the workpiece coated with anti-rust oil manually or by a robot and place it on the corresponding workpiece collection mechanism.

[0078] In step S5, the chips that are not attracted by the sheet magnetic plate 15 fall to the upper surface of the flexible rubber pad 302. As the air flow stirs, the chips move on the upper surface of the flexible rubber pad 302. When they pass through the iron chip receiving hole 16, they are attracted by the magnet sheet 301 into the iron chip receiving hole 16.

[0079] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
