Description

Technical Field

[0001] This utility model relates to the technical field of bolt anti-corrosion processing devices, specifically to an anti-corrosion processing device for bolts inside a guide rod. Background Technology

[0002] Guide rods are common mechanical components, typically used to guide moving parts along a straight line or a specific trajectory. They are now used in various mechanical systems. Bolts, as common connecting parts between guide rods and mechanical equipment, directly determine the connection stability of the guide rods due to their performance. Therefore, bolts need to be regularly treated with anti-corrosion processes.

[0003] In the existing technology, hot-dip galvanizing is usually used to treat bolts for corrosion protection. This involves placing the bolts in a container with holes and immersing the container in a zinc bath, allowing the zinc liquid to adhere to the bolt surface and form a coating, thus protecting the bolts from corrosion.

[0004] Because the container contains a large number of bolts, some bolts do not make sufficient contact with the zinc liquid when entering the zinc bath, which affects the uniform adhesion of the zinc liquid to the bolt surface and thus affects the overall anti-corrosion treatment effect of the bolts. On the other hand, when the container is removed from the zinc bath after the anti-corrosion treatment is completed, some zinc liquid will inevitably adhere to the container, which not only affects the container's placement environment but also increases cleaning costs and time.

[0005] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Utility Model Content

[0028] [First Embodiment]

[0029] like Figure 1-4 The image shows a corrosion-resistant processing device for internal bolts of a guide rod provided in the first embodiment of this utility model. Figure 1 As shown, the system includes a tank 1 filled with molten zinc for corrosion protection of bolts. An electric heating rod 7 is installed on the inner wall of the tank 1. When connected to an external power source, the electric heating rod 7 heats the molten zinc inside the tank 1, maintaining its temperature within a suitable range for corrosion protection. A frame 4 is fixed to the top of the tank 1, and an arm 5 is slidably mounted between the two frames 4. A drive motor is mounted on one side of the frame 4, and its output is fixedly connected to a lead screw rotatably mounted inside the frame 4. One end of the arm 5 is sleeved around the lead screw and threadedly connected to it. The output power of the drive motor drives the lead screw to rotate, causing the arm 5, threadedly connected to the lead screw, to slide between the two frames 4. A hydraulic rod 6 is installed at the bottom of the arm 5. The lifting and extending movement of the hydraulic rod 6 allows the container containing the bolts to be immersed downwards into the molten zinc in the tank 1 or pulled upwards out of the molten zinc in the tank 1.

[0030] The improvement of this embodiment compared to the prior art is as follows: the output end of the hydraulic rod 6 is equipped with an auxiliary device 2 capable of controlling the bolt, and a collection device 3 is set inside the pool body 1; by setting the auxiliary device, the perforated container is continuously shaken left and right in the zinc bath, so that the position of the bolt inside the zinc bath changes, thereby making the bolt fully contact the zinc bath, improving the contact effect between the bolt and the zinc bath, and improving the zinc plating and corrosion protection effect of the bolt; by setting the collection device, the perforated container can be temporarily placed in the collection device before it leaves the pool body and moves to the next process, and the attached zinc bath can be collected by the collection device, reducing the impact on the container placement environment, and reducing cleaning costs and time.

[0031] like Figure 2-3As shown, the auxiliary device 2 in this embodiment includes a rotating plate 21 rotatably mounted on the bottom of the outer side of the output end of the hydraulic rod 6. Electric push rods 22 are symmetrically arranged on both sides of the top of the rotating plate 21. A clamping rod 23 is installed on the output end of the electric push rod 22. The clamping rod 23 is slidably arranged inside the rotating plate 21 and can extend and retract relative to the electric push rod 22. The electric push rod 22 drives the clamping rods 23 on both sides to move towards or away from each other, thereby realizing the operation of clamping the container containing bolts inward and releasing it outward.

[0032] In order to make the perforated container continuously sway left and right in the zinc bath, a groove plate 27 is fixed to the top of the outer side of the output end of the hydraulic rod 6. A servo motor 210 is set on one side of the groove plate 27. A half gear 24 is fixed to the output end of the servo motor 210. A toothed plate 25 is fixed to the top of the rotating plate 21. The half gear 24 meshes with the toothed plate 25. The output power of the servo motor 210 drives the half gear 24 to rotate. Through the meshing of the half gear 24 with the toothed plate 25, the rotating plate 21, which is fixed to the toothed plate 25, is driven to rotate around the hinge point on the outer side of the output end of the hydraulic rod 6. Through the continuous forward and reverse drive of the servo motor 210, the perforated container is made to continuously sway left and right in the zinc bath.

[0033] To facilitate the effect of limiting the swaying, an elliptical groove 28 is provided inside the groove plate 27. A positioning rod 29 is fixed to the top of the rotating plate 21. The top of the positioning rod 29 extends into the interior of the elliptical groove 28. The inner diameter of the elliptical groove 28 is slightly larger than the outer diameter of the positioning rod 29 so that the positioning rod 29 can offset and sway inside the elliptical groove 28. At the same time, the inner diameter of the elliptical groove 28 should not be too large so that the swaying angle of the positioning rod 29 can be limited by the inner wall of the elliptical groove 28. On this basis, in order to achieve good contact with the outer wall of the positioning rod 29 and thus extend the service life, an elastic washer 211 is fixedly connected to the inner wall of the elliptical groove 28. The elastic washer 211 achieves flexible contact while realizing vibration reduction and shock absorption.

[0034] Furthermore, to achieve the automatic reset effect after shaking, the outer periphery of the positioning rod 29 is fitted with an elastic element 26. The two ends of the elastic element 26 are fixedly connected to the bottom of the slot plate 27 and the top of the rotating plate 21, respectively. After the rotating plate 21 rotates around the hinge point outside the output end of the hydraulic rod 6 to achieve the shaking effect on the bolts inside the container, the elastic restoring force provided by the elastic element 26 helps the rotating plate 21 to reset.

[0035] like Figure 4As shown, a slot 31 is provided on one side of the pool body 1. The collection device 3 includes a collection box 32, with a slot at the top. A rod 33 is fixedly connected to the inner side of the collection box 32, and the rod 33 is inserted into the slot 31. The insertion and engagement between the rod 33 and the slot 31 facilitates the loading and unloading of the collection box 32 from the side wall of the pool body 1. By providing the collection device 3, perforated containers can be temporarily placed in the collection box 32 before being moved from the pool body to the next process. The attached zinc liquid can be collected by the collection device, reducing the impact on the container's placement environment and reducing cleaning costs and time. To improve loading and unloading stability and reduce wear during insertion and unloading, several linearly distributed rubber protrusions 34 are fixedly connected to the outer side of the rod 33. To facilitate the loading and unloading control of the collection box 32, an auxiliary rod 35 is fixedly connected to the outer side of the collection box 32.

[0036] The specific working process of this embodiment is as follows:

[0037] When hot-dip galvanizing bolts using an anti-corrosion processing device, first insert the rod 33 on one side of the collection box 32 into the slot 31 on the side wall of the pool body 1, install the collection box 32 on one side of the pool body 1, and then add high-temperature zinc liquid into the pool body 1. The temperature of the zinc liquid is maintained within a suitable temperature range by the electric heating rod 7 inside the pool body 1.

[0038] The control box on one side of the pool body 1 controls the drive motor at the top of the frame 4 to drive the lead screw to rotate and control the arm 5 to move at the top of the frame 4 until it reaches the appropriate position, until the two clamping rods 23 are moved to the two sides of the perforated container with bolts. Then, the output end of the hydraulic rod 6 is controlled to extend downward to control the rotating plate 21 to descend. The electric push rod 22 retracts and drives the two clamping rods 23 to move towards each other, so that the clamping rods 23 clamp the two sides of the perforated container and hold the perforated container. Then, the output end of the hydraulic rod 6 is controlled to rise and retract, and the arm 5 is controlled to move to the position until it is above the pool body 1. The hydraulic rod 6 is controlled to extend to immerse the perforated container into the high-temperature zinc liquid. The zinc liquid will enter the container through the holes on the outer surface of the perforated container and adhere to the bolt surface.

[0039] Simultaneously, the servo motor 210 is activated to control the rotation of the half gear 24. During the rotation of the half gear 24, it meshes with the toothed plate 25 at the top of the rotating plate 21, causing the rotating plate 21 to rotate to one side and compress the elastic element 26, so that the rotating plate 21 and the perforated container tilt to a preset angle. The compressed elastic element 26 provides elastic restoring force to push the rotating plate 21 to rotate downward to its original position. Through the forward and reverse drive of the servo motor 210, the rotating plate 21 and the perforated container sway left and right inside the pool body 1, causing the bolts inside the perforated container to sway, thereby improving the contact effect between the bolts and the high-temperature zinc liquid.

[0040] After the anti-corrosion processing is completed, the servo motor 210 is turned off, and the rotating plate 21 and the perforated container are raised by the hydraulic rod 6. The drive motor at the top of the pneumatic frame 4 controls the movement of the arm 5. Then, the perforated container is lowered by the separation movement of the electric push rod 22. Before the perforated container leaves the pool 1 and moves to the next process, it will be temporarily placed in the collection box 32. The collection box 32 collects the zinc liquid and avoids the zinc liquid dripping into the processing environment as much as possible. Pulling the collection box 32 will pull the insert rod 33 out of the slot 31 and remove the collection box 32 to process the zinc liquid inside.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may use the disclosed technical content to make changes or modifications to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the utility model's technical solution, still fall within the protection scope of this utility model's technical solution. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.
