Description

Technical Field

[0001] This utility model relates to the technical field of rust-preventive oil performance testing, specifically to a rust-preventive oil corrosion-preventive performance testing device. Background Technology

[0002] Rust-preventive oil is a reddish-brown oil-based solvent with rust-preventive properties. It consists of oil-soluble corrosion inhibitors, base oils, and auxiliary additives. Based on performance and application, rust-preventive oils can be classified into fingerprint-removing rust-preventive oils, water-dilutable rust-preventive oils, solvent-dilutable rust-preventive oils, dual-purpose rust-preventive and lubricating oils, storage rust-preventive oils, displacement rust-preventive oils, thin-film oils, rust-preventive greases, and vapor-phase rust-preventive oils. Commonly used corrosion inhibitors in rust-preventive oils include alkaline earth metal salts of fatty acids or naphthenic acids, lead naphthenate, zinc naphthenate, sodium petroleum sulfonate, barium petroleum sulfonate, calcium petroleum sulfonate, trioleic tallow diamine, and rosin amine. During the production and processing of rust-preventive oils, rust-preventive performance testing is necessary to ensure its performance and subsequent usability. This testing requires specialized testing equipment.

[0003] In response to this, CN220170828U proposed a rust-preventive oil corrosion resistance testing device. The device opens an overflow hole corresponding to the height of the workpiece and uses a plug to block other overflow holes, allowing acidic or alkaline solutions that do not completely submerge the workpiece to flow out from the overflow holes. Then, the spraying is stopped. By creating a critical surface between the workpiece and the corrosive solution, a sufficient chemical reaction can occur at the critical surface of the workpiece, which can fully test the rust-preventive performance of the rust-preventive oil.

[0004] While the above-mentioned technical solutions can ensure that the test solution is tested at the critical surface during the testing process, thus improving accuracy, a certain amount of acid and alkali solution still adheres to the upper surface of the test workpiece and cannot be discharged. Ordinary testing devices can only automatically spray rust-preventive oil during testing, and the remaining solution on the workpiece still needs to be manually cleaned by the staff after the test. Prolonged cleaning can easily lead to contact with such acid and alkali corrosive solutions, causing skin ulcers for the staff and reducing the safety of the testing device. In view of this, this design proposes a rust-preventive oil corrosion resistance testing device. Utility Model Content

[0005] The purpose of this invention is to provide a device for testing the anti-rust and anti-corrosion performance of rust-preventive oil, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model proposes a rust-preventive oil corrosion resistance testing device, including a test chamber and a spraying mechanism, a support mechanism, and a drive assembly all mounted on the test chamber;

[0007] The spraying mechanism includes first limiting grooves on the upper edges of both sides of the inner wall of the test chamber. Sliders are slidably connected to the inner walls of the two first limiting grooves. Mounting covers are fixedly provided on one side of each of the two sliders. A support tube is rotatably connected between the two mounting covers. Multiple nozzles are equidistantly connected to one side of the support tube. A support frame is fixedly provided on the other side of the support tube. Multiple support shafts are equidistantly connected to the bottom of the support frame. A scraper is fixedly provided at the bottom of each support shaft. A spring is sleeved on the outer wall of one end of each support shaft. The two ends of each spring are fixedly connected to the bottom of the support frame and the top of the scraper, respectively.

[0008] In one example, a first motor is installed on the inner wall of one of the mounting covers, and one end of the support tube passes through the inner wall of the mounting cover and is fixedly connected to the output end of the first motor. Electric push rods are installed on one side of the inner wall of both first limiting slides, and the output ends of the two electric push rods are fixedly connected to one side of the two sliders respectively.

[0009] In one example, a liquid storage tank is installed on the edge of the top side of the test box. Two connecting pipes are installed on the top of the liquid storage tank. One of the connecting pipes has a conduit inserted through its inner wall, and one end of the conduit is inserted through the inner wall of the support pipe.

[0010] In one example, the support mechanism includes a test platform installed in the middle of the inner wall of the test chamber, with a leakage hole on one side of the top of the test platform and second limiting grooves on both sides of the outer wall of the test platform.

[0011] In one example, a sealing frame is slidably connected between the inner walls of the two second limiting grooves, and one side of the sealing frame contacts the bottom of the test bench, with a rubber pad fixedly provided at the middle position of the top of the sealing frame.

[0012] In one example, the drive assembly includes lead screws rotatably connected to both ends of the inner wall of the test chamber, and the outer walls of the two lead screws are respectively threaded to the inner walls of both ends of the sealing frame. One end of each of the two lead screws passes through the outer wall of one side of the test chamber and is connected to a synchronous pulley. The outer walls of the two synchronous pulleys are fitted with synchronous belt strips. The other end of one of the lead screws passes through the outer wall of the other side of the test chamber and is connected to a second motor.

[0013] In one example, a drain pipe is inserted and connected to the lower edge of one side of the outer wall of the test chamber, and four support legs are fixedly provided at the bottom of the test chamber.

[0014] In one example, a control panel is installed on one side of the outer wall of the test chamber, and the first motor, electric push rod and the second motor are all electrically connected to an external power supply through the control panel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a spraying mechanism, nozzles and support frames are respectively set on both sides of the support pipe at the upper end of the spraying mechanism. When spraying rust-preventive oil, the first motor is driven to rotate the support pipe so that the nozzles face downwards and spray rust-preventive oil to cover the test workpiece. After the test is completed, the support pipe is rotated again so that the support frame faces downwards, and the electric push rod pushes the slider to slide in the first limit groove so that the scraper scrapes the surface of the test workpiece and scrapes off the solution attached to its surface. There is no need for manual cleaning by the staff, which reduces the risk of the staff's skin being corroded and ulcerated by acid and alkali solutions and improves the safety of the device in testing and use.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a rust-preventive oil corrosion resistance testing device, including a test box 1 and a spraying mechanism 2, a support mechanism 5 and a drive component 6, all installed on the test box 1;

[0023] The spraying mechanism 2 includes first limiting grooves 201 opened on the upper edges of both sides of the inner wall of the test chamber 1. Slider 202 is slidably connected to the inner walls of the two first limiting grooves 201. Mounting cover 203 is fixedly provided on one side of each of the two sliders 202. Support tube 204 is rotatably connected between the two mounting covers 203. Multiple nozzles 205 are equidistantly connected to one side of the support tube 204. Support frame 206 is fixedly provided on the other side of the support tube 204. Multiple support shafts 207 are equidistantly connected to the bottom of the support frame 206. Scraper 208 is fixedly provided at the bottom of each support shaft 207. Spring 209 is sleeved on the outer wall of one end of each support shaft 207. The two ends of each spring 209 are fixedly connected to the bottom of the support frame 206 and the top of the scraper 208, respectively.

[0024] In use, the test workpiece is subjected to acid and alkali corrosion solution by the support mechanism 5. The solution is poured into the test platform 501 on the support mechanism 5 for acid and alkali corrosion. Then, the first motor 210 inside the mounting cover 203 on the spraying mechanism 2 is activated, driving the support tube 204 to rotate. This causes the nozzle 205 to point downwards towards the test workpiece on the support mechanism 5. Rust-preventive oil from the storage tank 3 is then introduced into the support tube 204 through the conduit 4 via the nozzle 205 and sprayed out. The electric push rod 211 is activated, causing the slider 202 to move the spraying mechanism 2 at a constant speed above the workpiece via the first limiting groove 201, thus evenly spraying the rust-preventive oil onto the workpiece surface for rust prevention testing. After the test, the solution is removed by the support mechanism 5. The support mechanism 5 discharges the acid and alkali solution, and at the same time, the first motor 210 is started, causing the support tube 204 to rotate again, so that the nozzle 205 faces upward and the support frame 206 faces downward. The scraper 208 at the bottom of the support frame 206 contacts and presses against the upper side of the workpiece. While pressing, the support shaft 207 on the scraper 208 passes through the support frame 206 and compresses the spring 209, so that the scraper 208 fully contacts the test workpiece. The electric push rod 211 is started again, which moves the slider 202 in the first limit groove 201, thereby causing the scraper 208 to scrape the surface of the workpiece and scrape off all the solution attached above that has not been discharged. This eliminates the need for manual cleaning by the staff, reduces the risk of skin corrosion and ulceration caused by the acid and alkali solution, and improves the safety of the device during testing.

[0025] One of the mounting covers 203 has a first motor 210 installed on its inner wall, and one end of the support tube 204 passes through the inner wall of the mounting cover 203 and is fixedly connected to the output end of the first motor 210. One side of the inner wall of each of the two first limiting slide grooves 201 is equipped with an electric push rod 211, and the output ends of the two electric push rods 211 are fixedly connected to one side of each of the two sliders 202. The first motor 210 is enclosed and protected in the mounting cover 203, making it less likely to be damaged by the solution. At the same time, the two electric push rods 211 can be synchronously extended and retracted by the control panel.

[0026] Furthermore, a liquid storage tank 3 is installed on the edge of the top side of the test chamber 1. Two connecting pipes are installed on the top of the liquid storage tank 3. One of the connecting pipes has a conduit 4 inserted through its inner wall, and one end of the conduit 4 is inserted through its inner wall. One of the two connecting pipes on the liquid storage tank 3 is an inlet pipe, and the other is connected to the outlet pipe through the conduit 4. The inlet pipe can be sealed with a stopper when not in use.

[0027] Furthermore, the support mechanism 5 includes a test platform 501 installed in the middle of the inner wall of the test chamber 1. A drain hole 502 is provided on one side of the top of the test platform 501, and second limiting grooves 503 are provided on both sides of the outer wall of the test platform 501. The test platform 501 is as described in the appendix to the instruction manual. Figure 4 As shown, its top is designed to be concave to facilitate the support of test workpieces and acid / alkali solutions.

[0028] A sealing frame 504 is slidably connected between the inner walls of the two second limiting slide grooves 503, and one side of the sealing frame 504 contacts the bottom of the test platform 501. A rubber pad 505 is fixedly provided at the middle position of the top of the sealing frame 504. During the test, the sealing frame 504 slides in the second limiting slide groove 503 under the drive component 6, so that one side of it blocks the bottom of the leak hole 502, so that the rubber pad 505 blocks the leak hole 502, so that the solution will not leak during the test. After the test is completed, the sealing frame 504 is driven by the drive component 6 to move, and the rubber pad 505 is disengaged from the bottom of the leak hole 502, so that the leak hole 502 opens and the liquid can be drained automatically. The sealing frame 504 contacts the bottom of the test platform 501, and the rubber pad 505 on it is pressed against the bottom of the test platform 501. When the rubber pad 505 is below the leak hole 502, it loses the pressure, and the rubber pad 505 returns to its original thickness due to the elasticity, thus blocking the leak hole 502.

[0029] Furthermore, the drive assembly 6 includes lead screws 601 rotatably connected to both ends of the inner wall of the test chamber 1, and the outer walls of the two lead screws 601 are threadedly connected to the inner walls of both ends of the sealing frame 504. One end of each lead screw 601 passes through the outer wall of one side of the test chamber 1 and is connected to a synchronous pulley 602. The outer walls of the two synchronous pulleys 602 are fitted with synchronous belt strips 603. The other end of one lead screw 601 passes through the outer wall of the other side of the test chamber 1 and is connected to a second motor 604. When the sealing frame 504 slides in the second limiting slide groove 503, the second motor 604 is started so that the two lead screws 601 rotate synchronously under the linkage of the synchronous pulleys 602 and the synchronous belt strips 603, and then are threadedly connected to the sealing frame 504 so that the sealing frame 504 can slide in the second limiting slide groove 503.

[0030] Furthermore, a drain pipe 7 is inserted and connected to the lower edge of one side of the outer wall of the test chamber 1. Four support legs are fixedly installed at the bottom of the test chamber 1. The drain pipe 7 is plugged with a stopper when no liquid is drained to prevent leakage.

Each embodiment focuses on its differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions of the method embodiments.

Various modifications and variations can be made to this utility model by those skilled in the art.
