Description

Technical Field

[0001] This utility model relates to the field of rivet processing, and in particular to a surface treatment device for rivet processing. Background Technology

[0002] A rivet is a nail-shaped object used to connect two parts (or components) with through holes and a cap at one end. Rivets are widely used in the construction industry. In order to prevent rivets from rusting and losing their fixation, effective rust prevention treatment is required. A common rust prevention method is to electroplat the surface of the rivet.

[0003] Traditional rivet surface treatment equipment typically involves manually placing the rivets into a perforated material cylinder, which is then immersed in zinc bath. However, the electroplating solution may be unevenly distributed in the electroplating bath, resulting in inconsistent electroplating thickness on the rivet surface.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a surface treatment device for rivet processing to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a surface treatment device for rivet processing, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A surface treatment device for riveting includes an electroplating tank. A placement frame is slidably connected to the inner wall of the electroplating tank, and a spring is fitted between the bottom end of the placement frame and the bottom end of the electroplating tank. Symmetrically distributed collision frames are provided on both sides of the upper end of the placement frame. A symmetrically distributed first support plate is fixedly connected to the rear end of the electroplating tank. A second support plate is fixedly connected to the upper end of each of the first support plates. A rotating plate is rotatably connected to the other end of each of the second support plates. A rotating shaft is rotatably connected between the two rotating plates. A motor is fixedly connected to one of the rotating plates. The drive end of the motor is fixedly connected to the rotating shaft. Symmetrically distributed eccentric wheels are also fixedly connected to the outer wall of the rotating shaft. The eccentric wheels abut against the upper end of the collision frames. A first base is fixedly connected to the lower end of the second support plate. A hydraulic telescopic rod is rotatably connected to the first base. The other end of the hydraulic telescopic rod is fixedly connected to a second base, and the second base is rotatably connected to the corresponding rotating plate. A drain pipe is also provided on the rear end face of the electroplating tank, and a drain valve is provided on the drain pipe.

[0008] A further technical solution involves fixing the lower end of the spring to the bottom of the electroplating tank, and abutting the upper end of the spring against the bottom of the placement frame.

[0009] A further technical solution is that a plurality of evenly distributed limiting blocks are fixedly connected to the side wall of the placement frame, and a plurality of evenly distributed limiting grooves are opened on the inner wall of the electroplating tank, and the limiting grooves correspond one-to-one with the limiting blocks, and the limiting blocks are slidably connected to the inner wall of the limiting grooves.

[0010] A further technical solution involves fixing multiple evenly distributed connecting ears to the upper end of each collision frame.

[0011] In a further technical solution, the placement frame, collision frame, limiting block, and connecting ear are an integrated structure.

[0012] A further technical solution involves creating a bevel on one side of the eccentric wheel.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. The eccentric wheel driven by the motor compresses the collision frame downwards, which in turn drives the placement frame to compress the spring downwards along the inner wall of the electroplating tank. The spring then drives the placement frame to slide upwards along the inner wall of the electroplating tank. The inertia of the rivets is used to disperse the plating solution. The placement frame and rivets also agitate the electroplating solution, effectively promoting the uniform distribution of the plating solution and significantly improving the uniformity and quality of the plating layer.

[0015] 2. Control the retraction of the hydraulic telescopic rod, and then the hydraulic telescopic rod drives the rotating plate to rotate through the second base. After that, the rotating plate drives the axis of rotation to move gradually closer to the first support plate, which effectively avoids interference with the eccentric wheel when the frame is pulled up.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figure 1-3 As shown, this utility model embodiment provides a surface treatment device for rivet processing, including an electroplating tank 1. A placement frame 2 is slidably connected to the inner wall of the electroplating tank 1, and a spring 7 is provided between the bottom end of the placement frame 2 and the bottom end of the electroplating tank 1. Symmetrically distributed collision frames 3 are provided on both sides of the upper end of the placement frame 2. A symmetrically distributed first support plate 8 is fixedly connected to the rear end of the electroplating tank 1. A second support plate 9 is fixedly connected to the upper end of each of the first support plates 8. A rotating plate 10 is rotatably connected to the other end of the second support plate 9. A rotating shaft 11 is rotatably connected between the two rotating plates 10. A fixed shaft 11 is provided on one of the rotating plates 10. A motor 13 is connected, and the drive end of the motor 13 is fixedly connected to the rotating shaft 11. The outer wall of the rotating shaft 11 is also fixedly connected to symmetrically distributed eccentric wheels 12, and the eccentric wheels 12 abut against the upper end of the collision frame 3. The lower end of the second support plate 9 is fixedly connected to the first base 16, and a hydraulic telescopic rod 14 is rotatably connected to the first base 16. The other end of the hydraulic telescopic rod 14 is fixedly connected to the second base 17, and the second base 17 is rotatably connected to the corresponding rotating plate 10. A drain pipe (not shown in the figure) is also provided on the rear end face of the electroplating tank 1, and a drain valve (not shown in the figure) is provided on the drain pipe.

[0024] Furthermore, the lower end of the spring 7 is fixedly connected to the bottom of the electroplating tank 1, and the upper end of the spring 7 abuts against the bottom of the placement frame 2.

[0025] Furthermore, multiple evenly distributed limiting blocks 5 are fixedly connected to the side wall of the placement frame 2, and multiple evenly distributed limiting grooves 4 are opened on the inner wall of the electroplating tank 1. The limiting grooves 4 correspond one-to-one with the limiting blocks 5. The limiting blocks 5 are slidably connected to the inner wall of the limiting grooves 4. The placement frame 2 is ensured to slide vertically on the inner wall of the electroplating tank 1 by the cooperation of the limiting grooves 4 and the limiting blocks 5, which effectively prevents the placement frame 2 from tilting.

[0026] Furthermore, each collision frame 3 is fixedly connected to a plurality of evenly distributed connecting ears 6 at its upper end. The plurality of connecting ears 6 are connected to a lifting device (not shown in the figure). When it is necessary to remove the placement frame 2 from the electroplating tank 1 or to remove the rivets in the placement frame 2, the placement frame 2 is lifted by the connecting ears 6 in conjunction with the lifting device.

[0027] Furthermore, the placement frame 2, collision frame 3, limiting block 5, and connecting ear 6 are an integral structure.

[0028] Furthermore, a bevel 18 is provided on one side of the eccentric wheel 12. The bevel 18 facilitates the sudden speed change of the placement frame 2 when it rises under the action of the spring 7, thereby causing the rivets inside the placement frame 2 to move. The placement frame 2 and the rivets will stir the electroplating solution, making it more evenly cover the surface of the rivets, thereby improving the uniformity of the plating layer.

[0029] Furthermore, the outer wall of the eccentric wheel 12 is covered with a sound insulation plate 15 to reduce noise.

[0030] Specifically, the eccentric wheel 12 driven by the motor 13 compresses the collision frame 3 downwards, and the collision frame 3 drives the placement frame 2 to compress the spring 7 downwards along the inner wall of the electroplating tank 1. The spring 7 drives the placement frame 2 to slide upwards along the inner wall of the electroplating tank 1, utilizing the inertia of the rivets to disperse them. In addition, the placement frame 2 and the rivets also agitate the electroplating solution, effectively promoting the uniform distribution of the electroplating solution and significantly improving the uniformity and quality of the coating. The hydraulic telescopic rod 14 is controlled to retract, and then the hydraulic telescopic rod 14 drives the rotating plate 10 to rotate through the second base 17. After that, the rotating plate 10 drives the rotating shaft 11 to move towards the first support plate 8, effectively avoiding interference with the eccentric wheel 12 when the placement frame 2 is pulled upwards.

[0031] The working principle of this utility model is as follows: The rivet is placed in the placement frame 2, and then the motor 13 is controlled to rotate clockwise. The motor 13 then drives two eccentric wheels 12 to rotate via the rotating shaft 11. Next, the outer wall of the eccentric wheels 12 presses downward against the collision frame 3. Subsequently, the collision frame 3 drives the placement frame 2 to slide downward along the inner wall of the electroplating tank 1, compressing the spring 7, until the farthest point of the eccentric wheel 12 from the axis of the rotating shaft 11 contacts the collision frame 3. At this point, the rivet in the placement frame 2 has a downward inertial direction. As the eccentric wheel 12 continues to rotate, it disengages from the collision frame 3. Then, the spring 7 pushes the placement frame 2 upward along the inner wall of the electroplating tank 1, causing the placement frame 2 to collide with the rivet, thus vibrating and separating the rivet. Simultaneously, the electroplating solution in the electroplating tank 1 is agitated, making it more evenly cover the rivet surface, thereby improving the uniformity of the plating layer. As the spring 7 drives the placement frame 2 to continue rising, until the collision frame 3 and the eccentric wheel 12 collide, the rivet's inertial direction is downward. When the eccentric wheel 12 abuts, the rivet's inertial direction is upward. Then, the eccentric wheel 12 drives the placement frame 2 to descend sequentially through the collision frame 3. The placement frame 2 continues to rise, and the placement frame 2 and the rivet agitate the electroplating solution in the electroplating tank 1, enabling the electroplating solution to cover the rivet surface more evenly, continuously repeating the above process. In addition, when it is necessary to pull up the placement frame 2 to remove the rivet, the hydraulic telescopic rod 14 is controlled to retract. Then, the hydraulic telescopic rod 14 drives the rotating plate 10 to rotate through the second base 17. After that, the rotating plate 10 drives the rotating shaft 11 to move towards the first support plate 8. Then, the rotating shaft 11 synchronously drives the eccentric wheel 12 and the motor 13 to move until the rotating shaft 11 is directly above the inner wall of the electroplating tank 1. At this time, the lifting device drives the placement frame 2 to slide upward along the inner wall of the electroplating tank 1 through the connecting lug 6 and the collision frame 3. Then, the placement frame 2 drives the rivet to move upward and remove it from the electroplating solution.

[0032] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
