Description

Technical Field

[0001] This utility model belongs to the field of electroplating technology, and in particular relates to a special roller for electroplating workpieces. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys onto the surface of certain metals. It is used to improve the wear resistance, conductivity, reflectivity, corrosion resistance and aesthetics of workpieces. Barrel plating is a common electroplating method that is suitable for small parts that cannot or are not suitable for mounting due to their shape, size and other factors. The barrel is one of the most important basic equipment for barrel plating.

[0003] A barrel plating cylinder is disclosed in document CN221371345U, including a drum. A drive gear is provided on one side of the drum, and a drive assembly is connected above the drive gear. The drive assembly is used to drive the drum to rotate. A spray pipe is provided inside the drum. One end of the spray pipe is connected to a circulation pump box, and one end of the circulation pump box is connected to a liquid extraction pipe. The circulation pump box pumps the solution in the bath liquid into the drum through the spray pipe via the liquid extraction pipe. The spray pipe is used to spray the solution onto the surface of the workpiece inside the drum.

[0004] However, it still has the following drawbacks in practical use:

[0005] The aforementioned barrel plating cylinder uses a roller to place and electroplate workpieces. However, during use, it is not convenient to classify and place different workpieces at the same time, thus making it inconvenient to electroplate different workpieces simultaneously.

[0006] The aforementioned barrel plating cylinder rotates via a drive gear and drive assembly. However, during use, the positions of the drive assembly and drive gear are fixed. This means that when the immersion depth of the barrel needs to be adjusted, the height of the entire device needs to be adjusted. This results in multiple structures of the device being immersed in the electroplating solution, leading to significant contamination of the electroplating solution.

[0007] To address these issues, we provide a special roller for workpiece electroplating. Utility Model Content

[0008] The purpose of this utility model is to provide a special roller for workpiece electroplating. The partition is positioned on the rotating shaft by the positioning rod, and the space of the cylinder formed by the cylinder plate and the cover plate is separated by the partition, which solves the problem that it is not convenient to electroplat different workpieces at the same time. At the same time, the second transmission rod drives the adjusting rod and the adjusting arm to rotate, thereby driving the mounting plate and the cylinder to move through the adjusting arm, which solves the problem that it is not convenient to adjust the immersion depth of the cylinder.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model is a special roller for workpiece electroplating, including a U-shaped frame, with mounting plates on both sides of the front end of the U-shaped frame through adjustment components, and a main component arranged between the mounting plates;

[0011] The main component includes a rotating shaft rotatably connected between mounting plates. Multiple positioning holes are equally spaced along the axial direction on the outer wall of the rotating shaft. Side plates are fitted on both sides of the outer wall of the rotating shaft. A cylindrical plate is fixedly connected between the side plates. A cover plate is fixedly connected to the cylindrical plate. Through holes are provided on both the cylindrical plate and the cover plate. Multiple partitions are equally spaced along the axial direction on the outer wall of the rotating shaft. The partitions are all located inside the cylindrical plate. A positioning rod is threaded through the upper surface of each partition. The bottom end of the positioning rod is threaded into the interior of one of the positioning holes.

[0012] The adjustment assembly includes an adjustment rod rotatably connected to the lower part of the U-shaped frame. One end of the adjustment rod rotatably passes through a vertical support arm on one side of the U-shaped frame and is fitted with a large gear. Adjustment arms are fitted on both sides of the outer wall of the adjustment rod. The end of the adjustment arm away from the adjustment rod is fixedly connected to the mounting plate through a second connecting strip. A second transmission rod is rotatably connected to the vertical support arm in front of the U-shaped frame. A small gear is fitted on one end of the second transmission rod, and the small gear meshes with the upper part of the large gear.

[0013] A further feature of this invention is that a first transmission rod is rotatably connected to the vertical support arm on the other side of the U-shaped frame, and a first synchronous pulley is sleeved on both the rear end of the rotating shaft and the first transmission rod. The first synchronous pulleys are connected by a first synchronous belt.

[0014] A further feature of this invention is that a first drive motor is fixedly connected to the vertical support arm on the other side of the U-shaped frame via a first motor frame, and a second synchronous pulley is sleeved on the output shaft of the first drive motor and the rear end of the first transmission rod, and the second synchronous pulleys are connected by a second synchronous belt.

[0015] A further feature of this invention is that: both sides of the top of the transverse support arm of the U-shaped frame are fixedly connected to mounting rods, and the top of each mounting rod is fixedly connected to a fixing plate.

[0016] A further feature of this invention is that: multiple first fixing rods are fixedly connected at equal intervals along the horizontal direction on both sides of the top of the cylinder plate; multiple first connecting strips are welded at equal intervals along the horizontal direction on the upper surface of the cover plate; and the top of each first fixing rod passes through the first connecting strip and is threaded with a first fastening nut.

[0017] A further feature of this invention is that each of the positioning rods is fixedly connected to a rotating cap, and the rotating cap is located inside the groove on the upper surface of the partition plate.

[0018] A further feature of this invention is that a second fixing rod is welded to both the upper and lower surfaces of the mounting plate and the adjusting arm, and the end of the second fixing rod away from the mounting plate and the adjusting arm passes through the second connecting strip and is threaded with a second fastening nut.

[0019] A further feature of this invention is that the other end of the second transmission rod rotatably passes through the vertical support arm on one side of the U-shaped frame and extends to the inner side of the U-shaped frame. A second drive motor is fixedly connected to the vertical support arm on one side of the U-shaped frame via a second motor frame. A third synchronous pulley is sleeved on the other end of the second transmission rod and the output shaft of the second drive motor. The third synchronous pulleys are connected by a third synchronous belt.

[0020] This utility model has the following beneficial effects:

[0021] This invention, through the setting of a main component, involves removing the cover plate and turning the nut, which drives the positioning rod to rotate synchronously. This causes the bottom end of the positioning rod to move out of the positioning hole and apply external force to the partition, causing the partition to slide along the axial direction of the rotating shaft. When the partition reaches the designated position, the nut is turned again, causing the bottom end of the positioning rod to be threaded into the new positioning hole. The partition divides the internal space of the cylinder, and the positioning rod adjusts the position of the partition on the rotating shaft, thereby enabling the adjustment of the size of multiple internal spaces in the cylinder. This facilitates the placement of different workpieces and allows for simultaneous electroplating of different workpieces, improving work efficiency.

[0022] This invention, by setting up an adjustment component, starts a second drive motor. The output shaft of the second drive motor drives a second transmission rod to rotate via a third synchronous pulley and a third synchronous belt. The second transmission rod, through the meshing connection between a small gear and a large gear, drives an adjustment rod to rotate. The adjustment rod, through an adjustment arm, drives the mounting plate to rotate, causing the cylinder between the mounting plates to move. This allows for adjustment of the immersion depth of the cylinder in the electroplating solution, facilitating the adjustment of the immersion depth of the cylinder in the electroplating solution and preventing the structure outside the cylinder from being immersed in the electroplating solution, ensuring the cleanliness of the electroplating solution and facilitating the electroplating of the workpiece.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0036] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this is the first embodiment of the present invention. This embodiment provides a special roller for workpiece electroplating, including a U-shaped frame 1, a mounting plate 2, and a main body assembly 3. The main body assembly 3 includes a rotating shaft 301, a side plate 302, a cylindrical plate 303, a cover plate 304, a partition plate 305, and a positioning rod 306. The positioning rod 306 positions the partition plate 305 on the rotating shaft 301, and the partition plate 305 divides the cylindrical space enclosed by the cylindrical plate 303 and the cover plate 304, thus solving the problem that it is inconvenient to electroplat different workpieces at the same time.

[0038] Specifically, the rotating shaft 301 is rotatably connected between two mounting plates 2 along its lateral direction. Multiple positioning holes 301a are equally spaced along its axial direction on the outer wall of the rotating shaft 301. Side plates 302 are fitted on both sides of the outer wall of the rotating shaft 301. A cylindrical plate 303 is fixedly connected between the side plates 302. A cover plate 304 is fixedly connected to the cylindrical plate 303. Both the cylindrical plate 303 and the cover plate 304 have through holes 303a. Multiple partition plates 305 are equally spaced along its axial direction on the outer wall of the rotating shaft 301. The partition plates 305 are all located inside the cylindrical plate 303. Positioning rods 306 are threaded through the upper surface of each partition plate 305. The bottom end of 6 is threaded into the interior of one of the positioning holes 301a. The rotating shaft 301 is used to drive the structure such as the cylinder plate 303 to rotate in the electroplating solution. The side plate 302 is used to install the cylinder plate 303. The side section of the cylinder plate 303 is hexagonal. The cylinder plate 303 and the cover plate 304 are used to put the workpiece into the electroplating solution. The partition plate 305 is used to divide the internal space enclosed by the cylinder plate 303 and the cover plate 304, so as to facilitate the placement of different workpieces. The positioning rod 306 and the positioning hole 301a are used to position the partition plate 305 on the rotating shaft 301.

[0039] Furthermore, a first transmission rod 307 is rotatably connected to the vertical support arm on the other side of the U-shaped frame 1. A first synchronous pulley 301b is sleeved on the rear end of the rotating shaft 301 and the first transmission rod 307. The first synchronous pulleys 301b are connected to each other by a first synchronous belt 307a.

[0040] On the other side of the U-shaped frame 1, a first drive motor 308 is fixedly connected to the vertical support arm via a first motor frame 308a. The output shaft of the first drive motor 308 and the rear end of the first transmission rod 307 are both fitted with second synchronous pulleys 308b. The second synchronous pulleys 308b are connected to each other via a second synchronous belt 308c.

[0041] The top two sides of the horizontal support arm of the U-shaped frame 1 are fixedly connected with mounting rods 101, and the top of the mounting rods 101 are fixedly connected with fixing plates 102.

[0042] Multiple first fixing rods 303b are fixedly connected at equal intervals along the horizontal direction on both sides of the top of the cylinder plate 303. Multiple first connecting strips 304a are welded at equal intervals along the horizontal direction on the upper surface of the cover plate 304. The top of the first fixing rod 303b passes through the first connecting strip 304a and is threaded with a first fastening nut 303c.

[0043] The top of each positioning rod 306 is fixedly connected with a rotating cap 306a, which is located inside the groove on the upper surface of the partition plate 305.

[0044] The operation process of this embodiment is as follows: When it is necessary to adjust the position of the partition 305 on the rotating shaft 301, remove the cover plate 304 and turn the screw cap 306a. The screw cap 306a drives the positioning rod 306 to rotate synchronously, so that the bottom end of the positioning rod 306 moves out of the positioning hole 301a and applies an external force to the partition 305, so that the partition 305 slides along the axial direction of the rotating shaft 301. When the partition 305 moves to the designated position, turn the screw cap 306a again, so that the bottom end of the positioning rod 306 is threaded into the new positioning hole 301a. Example 2

[0045] See also Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it also includes an adjustment component 4. The adjustment component 4 includes an adjustment rod 401, an adjustment arm 402, a second connecting bar 403, and a second transmission rod 404. The second transmission rod 404 drives the adjustment rod 401 and the adjustment arm 402 to rotate, thereby driving the mounting plate 2 and the cylinder to move through the adjustment arm 402, thus solving the problem of the existing method of not being able to adjust the immersion depth of the cylinder.

[0046] Specifically, the adjusting rod 401 is rotatably connected to the lower interior of the U-shaped frame 1. One end of the adjusting rod 401 rotatably passes through the vertical support arm on one side of the U-shaped frame 1 and is fitted with a large gear 401a. Adjusting arms 402 are fitted on both sides of the outer wall of the adjusting rod 401. The end of the adjusting arm 402 away from the adjusting rod 401 is fixedly connected to the mounting plate 2 through the second connecting strip 403. A second transmission rod 404 is rotatably connected to the vertical support arm in front of the U-shaped frame 1. A small gear 404a is fitted on one end of the second transmission rod 404. 404a meshes above the large gear 401a. The adjusting rod 401 is set to drive the adjusting arm 402 to rotate. The large gear 401a is set to drive the adjusting rod 401 to rotate. The adjusting arm 402 is set to drive the mounting plate 2 to rotate, thereby driving the cylinder between the mounting plates 2 to move. The second connecting bar 403 is set to connect the mounting plate 2 and the adjusting arm 402. The second transmission rod 404 and the small gear 404a are set to drive the large gear 401a to rotate.

[0047] Furthermore, a second fixing rod 402a is welded to both the upper and lower surfaces of the mounting plate 2 and the adjusting arm 402. The end of the second fixing rod 402a away from the mounting plate 2 and the adjusting arm 402 passes through the second connecting strip 403 and is threaded with a second fastening nut 402b.

[0048] The other end of the second transmission rod 404 rotates through the vertical support arm on one side of the U-shaped frame 1 and extends to the inside of the U-shaped frame 1. The second drive motor 405 is fixedly connected to the vertical support arm on one side of the U-shaped frame 1 via the second motor frame 405a. The other end of the second transmission rod 404 and the output shaft of the second drive motor 405 are both fitted with third synchronous pulleys 405b. The third synchronous pulleys 405b are connected to each other by a third synchronous belt 405c.

[0049] The rest of the structure is the same as in Example 1.

[0050] The operation process of this embodiment is as follows: When it is necessary to adjust the immersion depth of the cylinder in the electroplating solution, the second drive motor 405 is started. The output shaft of the second drive motor 405 drives the second transmission rod 404 to rotate through the third synchronous pulley 405b and the third synchronous belt 405c. The second transmission rod 404 drives the adjusting rod 401 to rotate through the meshing connection between the small gear 404a and the large gear 401a. The adjusting rod 401 drives the mounting plate 2 to rotate through the adjusting arm 402, thereby driving the cylinder between the mounting plates 2 to move, thus realizing the adjustment of the immersion depth of the cylinder in the electroplating solution.
