Abstract
Description
Technical Field
[0001] This utility model relates to the field of rivet processing technology, specifically to a rivet surface treatment device. Background Technology
[0002] Blind rivets, also known as pop rivets, are fasteners used for single-sided riveting. They consist of a rivet core and a sleeve. During installation, the rivet gun pulls the rivet core, causing the hollow sleeve to expand under pressure and tightly adhere to the surface of the materials being joined, achieving single-sided riveting. As a commonly used fastener, blind rivets have a wide range of applications. These rivets are particularly suitable for riveting situations where it is inconvenient to use ordinary rivets, i.e., when it is not possible to work from both sides simultaneously. Therefore, they are widely used in products such as construction, automobiles, ships, aircraft, machinery, electrical appliances, and furniture. Among them, open-head flat-round head blind rivets are the most widely used, countersunk head blind rivets are suitable for riveting situations where a smooth surface is required, and closed-head blind rivets are suitable for riveting situations requiring higher load-bearing capacity and a certain degree of sealing performance.
[0003] During the processing of blind rivets, electroplating is required. Before electroplating, the blind rivets need to be pickled and passivated to remove oxide skin, oil stains and metal ions from the surface of the blind rivets. A common method is to put a large number of blind rivets into pickling solvent for passivation.
[0004] However, most current processing devices place the rivets in a solvent tank for passivation. Since a large number of rivets are being passivated, leaving them stationary in the solvent tank can prevent the bottom rivets from making sufficient contact with the solvent, thus affecting the pickling effect. Therefore, a rivet surface treatment device is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a surface treatment device for rivets, which has advantages such as improving pickling effect. It solves the problem that most current treatment devices place the rivets in a solvent tank for passivation. Since there are many rivets to be passivated, leaving them stationary in the solvent tank will cause some of the rivets at the bottom to not have sufficient contact with the solvent, thus affecting the pickling effect.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a rivet surface treatment device, comprising an acid pickling tank, a positioning frame slidably installed on the inner side of the acid pickling tank, a material frame inserted into the inner side of the positioning frame, a driving mechanism provided on the outer side of the positioning frame, and a stirring mechanism provided above the material frame.

A cam is fixedly installed on the output shaft of the first motor. A connecting rod is hinged to the outside of the cam. A slider is hinged to the end of the connecting rod away from the cam. An installation rod is fixedly connected between the slider and the positioning frame.
[0008] The stirring mechanism includes a fixed frame that is fixedly connected to the outside of the pickling tank. An electric push rod is fixedly installed on the top of the fixed frame. A connecting plate is fixedly installed on the output shaft of the electric push rod. A second motor is fixedly installed on the top of the connecting plate. A shaft is fixedly installed on the output shaft of the second motor. Blades are fixedly installed on the lower side of the shaft.
[0009] Furthermore, a guide rail is fixedly installed on the top of the fixed plate, and the slider slides in cooperation with the outer side of the guide rail.
[0010] Furthermore, the pickling tank has an opening near the mounting rod, and the mounting rod passes through the inside of the opening.
[0011] Furthermore, a pad is fixedly connected to the outside of the material frame. The pad is attached to the upper end of the positioning frame. There are two pads, which are symmetrically distributed on both sides of the material frame.
[0012] Furthermore, a handle is fixedly connected to the upper end of the material frame. There are two handles, which are symmetrically distributed on both sides of the upper end of the material frame.
[0013] Furthermore, the lower part of the material frame has several filtrate holes, and the cross-sectional shape of the fixing frame is L-shaped.
[0014] Furthermore, the connecting plate is slidably connected to the outer wall of the fixing frame, and the blade is located directly above the pickling tank.

[0016] Beneficial effects:
[0017] 1. This rivet surface treatment device, by starting the first motor, can drive the positioning frame to reciprocate along the inner side of the pickling tank. The positioning frame will drive the material frame to move synchronously, thereby causing the rivets in the material frame to shake. At the same time, the electric push rod is started to move the blades downward to the material frame in the pickling tank. By starting the second motor, the blades are driven to rotate, so that the blades can agitate the rivets in the material frame, avoiding multiple rivets stacking and affecting the contact with the solvent. With the combination of the shaking of the material frame and the agitation of the blades, the rivets are evenly distributed in the pickling tank, ensuring that each rivet can fully contact the pickling solvent, thus ensuring the pickling effect.

[0025] 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.
[0026] Please see Figures 1 to 5This embodiment of a rivet surface treatment device includes an acid pickling tank 1. A positioning frame 2 is slidably installed on the inner side of the acid pickling tank 1. A material frame 3 is inserted into the inner side of the positioning frame 2. The lower part of the material frame 3 has several filter holes 19 to facilitate the passage of acid pickling solvent through the material frame 3. A driving mechanism is provided on the outer side of the positioning frame 2. The driving mechanism includes a fixing plate 4 fixedly connected to the outside of the acid pickling tank 1. A first motor 5 is fixedly installed on the top of the fixing plate 4. A cam 6 is fixedly installed on the output shaft of the first motor 5. A connecting rod 7 is hinged to the outer side of the cam 6. A slider 8 is hinged to the end of the connecting rod 7 away from the cam 6. A guide rail 9 is fixedly installed on the top of the fixing plate 4. The slider 8 slides with the outer side of the guide rail 9. An installation rod 10 is fixedly connected between the slider 8 and the positioning frame 2. By starting the first motor 5, the cam 6 can be driven to rotate, which in turn drives the connecting rod 7 to rotate. The connecting rod 7 will then drive the slider 8 to reciprocate along the outside of the guide rail 9, thereby driving the positioning frame 2 to reciprocate along the inside of the pickling tank 1 via the mounting rod 10. The positioning frame 2 will then drive the material frame 3 to move synchronously, which in turn causes the pull studs inside the material frame 3 to vibrate.
[0027] The pickling tank 1 has an opening near the mounting rod 10, and the mounting rod 10 passes through the inside of the opening. The mounting rod 10 is clearance-fitted with the inside of the opening, and the mounting rod 10 can move along the inside of the opening.
[0028] It should be noted that a pad 17 is fixedly connected to the outside of the material frame 3. The pad 17 is close to the upper end of the positioning frame 2. There are two pads 17, which are symmetrically distributed on both sides of the material frame 3. The pads 17 facilitate the cooperation between the material frame 3 and the positioning frame 2, so that the material frame 3 will not separate downward from the positioning frame 2. The positioning frame 2 and the pad 17 cooperate to support the material frame 3.
[0029] It should be added that the upper end of the material frame 3 is fixedly connected with two handles 18, which are symmetrically distributed on both sides of the upper end of the material frame 3. The handles 18 facilitate the picking up of the material frame 3.
[0030] In this embodiment, a stirring mechanism is provided above the material frame 3. The stirring mechanism includes a fixed frame 11 fixedly connected to the outside of the pickling tank 1. The fixed frame 11 has an L-shaped cross-section. An electric push rod 12 is fixedly installed on the top of the fixed frame 11. A connecting plate 13 is fixedly installed on the output shaft of the electric push rod 12. The connecting plate 13 is slidably connected to the outer wall of the fixed frame 11. A second motor 14 is fixedly installed on the top of the connecting plate 13. A shaft 15 is fixedly installed on the output shaft of the second motor 14. A blade 16 is fixedly installed on the lower side of the shaft 15. The blade 16 is located directly above the pickling tank 1. The height of the connecting plate 13 can be adjusted by driving the electric push rod 12, thereby adjusting the height of the blade 16. When the blade 16 moves downward into the pickling tank 1, the second motor 14 is started to drive the shaft 15 to rotate, and the blade 16 rotates synchronously, so that the blade 16 can stir the pull studs in the material frame 3.
[0031] The working principle of the above embodiments is as follows:
[0032] In use, the first motor 5 is started to drive the cam 6 to rotate, which in turn drives the connecting rod 7 to rotate. The connecting rod 7 then drives the slider 8 to reciprocate along the outside of the guide rail 9. This, in turn, drives the positioning frame 2 to reciprocate along the inside of the pickling tank 1 via the mounting rod 10. The positioning frame 2 then drives the material frame 3 to move synchronously, which in turn causes the rivets inside the material frame 3 to vibrate. At the same time, the electric push rod 12 is started to drive the connecting plate 13 to move downward, moving the blade 16 downward to the material frame 3 inside the pickling tank 1. The second motor 14 is started to drive the shaft 15 to rotate, which in turn drives the blade 16 to rotate synchronously. This allows the blade 16 to agitate the rivets inside the material frame 3, preventing multiple rivets from stacking and affecting their contact with the solvent. With the vibration of the material frame 3 and the agitation of the blade 16 working together, the rivets are evenly distributed inside the pickling tank 1, ensuring that each rivet can fully contact the pickling solvent, thus guaranteeing the pickling effect.
[0033] After pickling is completed, turn off the first motor 5 and the second motor 14, start the electric push rod 12 to drive the connecting plate 13 to move upward, so that the blade 16 moves upward away from the pickling box 1 and the material frame 3, making it easier to remove the material frame 3.
[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
