Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing technology, and in particular to a rapid surface treatment device for spring manufacturing. Background Technology

[0002] Springs, as mechanical components utilizing the principle of elasticity, are made from elastic materials. They deform under external force and return to their original shape when the force is removed. They come in various forms, including helical, spiral, plate, and irregular shapes. Springs are often made of spring steel, and after manufacturing, their surface is often coated with a hard film rust inhibitor. This is to enhance their rust resistance and promote lubrication, ensuring the spring's long-term effective operation.

[0003] In response, a spring surface treatment machine with patent number "CN210876030U" first immerses the spring in an immersion tank for a period of time, allowing a layer of rust inhibitor to completely adhere to the spring surface. Then, the spring is placed in the middle of a support rod, causing it to rotate and thus splashing off excess rust inhibitor. However, when removing the spring from the immersion tank and placing it on the support rod, workers need to directly contact the liquid containing the rust inhibitor. Since the rust inhibitor contains harmful chemicals such as aromatic hydrocarbons and lead, this direct contact increases the health risks to workers, such as skin irritation and respiratory discomfort. Furthermore, the process of removing the spring and then spin-drying it is not only time-consuming but also increases the complexity and time cost of the operation. Therefore, this application proposes a rapid surface treatment device for spring manufacturing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid surface treatment device for spring manufacturing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid surface treatment device for spring manufacturing includes a worktable. A U-shaped frame is fixedly connected to the upper end of the worktable. A toothed gear, a first gear, and a second gear are rotatably connected to the bottom of the U-shaped frame. The first gear meshes with the toothed gear and the second gear. A rectangular sliding sleeve is fixedly connected to the lower end of the first gear. A rectangular sliding rod is slidably connected inside the rectangular sliding sleeve. A fixing mechanism for fixing the spring is installed at the lower end of the rectangular sliding rod. A reciprocating screw is fixedly connected to the lower end of the second gear. A nut is threaded onto the reciprocating screw. A connecting rod is fixedly connected to the side wall of the nut. A short rod is fixedly connected to the end of the connecting rod away from the nut. A guiding mechanism for guiding the nut is installed on the U-shaped frame. Two circular plates are fixedly connected to the rectangular sliding rod. The circular plates have grooves, and the short rod slides within the grooves.

[0007] Preferably, a motor is fixedly connected to the upper end of the U-shaped frame, and the output shaft of the motor is fixedly connected to the toothed gear.

[0008] Preferably, the fixing mechanism includes two screws and a fixing box, the screws are threadedly installed on both sides of the fixing box, and the screws pass through the fixing box.

[0009] Preferably, the guiding mechanism includes a slider, which is fixedly installed on the side wall of the nut, and a groove is provided on the inner wall of the U-shaped frame, in which the slider slides.

[0010] Preferably, the lower end of the workbench is fixedly connected to four support legs.

[0011] Preferably, a soaking tank is fixedly connected to the upper end of the workbench.

[0012] This utility model has the following beneficial effects:

[0013] 1. The rotation of the first and second gears causes the reciprocating screw to rotate. The nut drives the rectangular slide rod to reciprocate within the rectangular sleeve via the connecting rod. The rotation of the first gear also causes the rectangular sleeve to rotate, which in turn causes the rectangular slide rod to rotate. As the spring is immersed in the water, it rises while the rectangular slide rod rotates, causing the spring to shake off excess rust inhibitor. This eliminates the need for manual removal of the spring from the immersion tank, reducing the health risks to workers and improving work efficiency while saving time and costs.

[0014] 2. The fixing mechanism rotates the screws to bring the two screws closer together to clamp and fix the spring, so that the spring is fixed when it moves up and down and rotates, preventing the spring from coming out of the fixing box and causing the anti-rust liquid on the spring to splash out.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A rapid surface treatment device for spring manufacturing includes a workbench 1. A U-shaped frame 2 is fixedly connected to the upper end of the workbench 1. A toothed gear 3, a first gear 4, and a second gear 5 are rotatably connected to the bottom of the U-shaped frame 2. It should be noted that the toothed gear 3 only has half of its teeth. When the toothed gear 3 rotates to the other side, the toothed gear 3 does not mesh with the first gear 4, causing the first gear 4 to stop rotating. This allows the spring 20 to be immersed in the soaking tank 14 for a period of time. When the toothed gear 3 rotates to mesh with the first gear 4, the spring 20 has just finished soaking. Under the action of the first gear 4 and the second gear 5, the spring 20 rises and rotates at the same time, throwing out its excess rust inhibitor.

[0021] The first gear 4 meshes with the toothless gear 3 and the second gear 5. It should be noted that when the toothless gear 3 and the first gear 4 just reach the point of disengagement, the rotation of the reciprocating screw 6 causes the nut 7 to reach the point where it needs to move back and forth. When the toothless gear 3 meshes with the first gear 4 again, the first gear 4 drives the second gear 5 to rotate, causing the reciprocating screw 6 to rotate, which in turn causes the nut 7 to move in the opposite direction to the previous movement.

[0022] A rectangular sliding sleeve 12 is fixedly connected to the lower end of the first gear 4. A rectangular sliding rod 21 is slidably connected inside the rectangular sliding sleeve 12. It should be noted that the rectangular sliding sleeve 12 and the rectangular sliding rod 21 have a rectangular appearance. Therefore, the rotation of the rectangular sliding sleeve 12 will drive the rectangular sliding rod 21 inside the rectangular sliding sleeve 12 to rotate using the rectangular side wall, thereby achieving the effect of rotating and spinning the spring 20.

[0023] A fixing mechanism for fixing the spring is installed at the lower end of the rectangular slide bar 21. The fixing mechanism includes two screws 15 and a fixing box 19. The screws 15 are threaded on both sides of the fixing box 19 and pass through the fixing box 19.

[0024] The lower end of the second gear 5 is fixedly connected to a reciprocating lead screw 6, and a nut 7 is threaded onto the reciprocating lead screw 6. A connecting rod 8 is fixedly connected to the side wall of the nut 7, and a short rod 18 is fixedly connected to the end of the connecting rod 8 away from the nut 7. It should be noted that the connecting rod 8 adopts an arched design, and the height of the arch is slightly greater than the depth of the soaking tank 14, so that when the connecting rod 8 moves down, it will not cause the connecting rod 8 to contact the upper end of the soaking tank 14, thus avoiding collision between the connecting rod 8 and the soaking tank 14 and causing damage to the parts.

[0025] A guide mechanism for guiding the nut 7 is installed on the U-shaped frame 2. The guide mechanism includes a slider 10, which is fixedly installed on the side wall of the nut 7. A groove 9 is provided on the inner wall of the U-shaped frame 2, and the slider 10 slides in the groove 9.

[0026] Two circular plates 16 are fixedly connected to the rectangular slide rod 21. The circular plates 16 have grooves 17, and the short rod 18 slides within these grooves. It should be noted that when the circular plates 16 rotate, the short rod 18 slides within the grooves 17 without changing its position. The nut 7, through the connecting rod 8, moves the short rod 18 up and down, which in turn causes the rectangular slide rod 21 to extend and retract within the rectangular sleeve 12 via the circular plates 16.

[0027] A motor 11 is fixedly connected to the upper end of the U-shaped frame 2. The output shaft of the motor 11 is fixedly connected to the toothed gear 3. Four support legs 13 are fixedly connected to the lower end of the workbench 1. A soaking tank 14 is fixedly connected to the upper end of the workbench 1.

[0028] In this invention, rotating screw 15 brings the two screws 15 closer together, fixing spring 20 inside fixed box 19. Starting motor 11 drives toothed gear 3 to rotate. Toothed gear 3 meshes with first gear 4, and first gear 4 meshes with second gear 5. Therefore, the rotation of toothed gear 3 will drive the rotation of first gear 4, and the rotation of first gear 4 will drive the rotation of second gear 5.

[0029] The first gear 4 drives the rectangular slide rod 21 to rotate via the rectangular sliding sleeve 12, which in turn drives the fixed box 19 to rotate, causing the spring 20 to rotate. The rotation of the second gear 5 drives the reciprocating screw 6 to rotate, causing the nut 7 to move downward. The nut 7 drives the short rod 18 to move downward via the connecting rod 8. The short rod 18 drives the rectangular slide rod 21 to extend out of the rectangular sliding sleeve 12 via the circular plate 16, so that the spring 20 is immersed in the soaking tank 14.

[0030] When spring 20 is in complete contact with the rust inhibitor in the soaking tank 14, the toothed gear 3 disengages from the first gear 4, causing the second gear 5 to stop rotating. This allows spring 20 to remain in the soaking tank 14, achieving the purpose of soaking. When the toothed gear 3 rotates back and re-engages with the first gear 4, the first gear 4 drives the second gear 5 to rotate, causing the nut 7 to move upwards, lifting spring 20 off the soaking tank 14. Simultaneously, spring 20 rotates, shaking off excess rust inhibitor. During this upward rotation, the side wall of the soaking tank 14 blocks the ejected rust inhibitor, causing it to return to the tank. When spring 20 returns to its initial position, motor 11 stops.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
