Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a quick positioning fixture for electroplating. Background Technology

[0002] Electroplating, as a key process in surface treatment for improving workpiece performance, directly impacts product quality and production efficiency with its processing accuracy and efficiency. Traditional electroplating operations suffer from significant limitations in their positioning fixtures. The operation process is cumbersome, requiring multiple manual adjustments to hold and fix irregular workpieces, demanding extremely high operator skill. Furthermore, single-person operation struggles to simultaneously manage workpiece positioning and plating, easily leading to uneven plating thickness and missed plating due to clamping deviations. Existing fixtures often rely on a single fixed structure, exhibiting poor adaptability. Frequent fixture changes are necessary for small batches of multi-specification workpieces, further complicating the process. Extending production preparation time also increases equipment investment costs. In addition, the relative movement between the brush mechanism and the workpiece in traditional equipment is mostly manually controlled, resulting in low accuracy of the plating trajectory. Furthermore, the lack of linkage between brush solution replenishment and plating operation can easily lead to insufficient or excessive plating solution supply, affecting the stability of plating quality. Moreover, the existing equipment lacks coordination among its components, involves many manual intervention steps, and has large operational errors, making it difficult to meet the core requirements of rapid changeover, precision, and efficiency in modern production. This severely restricts the automation level and production efficiency of brush plating operations and cannot adapt to the flexible processing needs of small batches of multi-specification workpieces.

[0003] Therefore, those skilled in the art have provided a quick positioning fixture for brush plating to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. This rapid positioning fixture for electroplating integrates an adaptive clamping structure and a collaborative motion system to create a precise and efficient electroplating operation system. It effectively overcomes the pain points of traditional fixtures, such as cumbersome positioning and poor adaptability. The arc-shaped guide groove and the arc-shaped connecting groove of the middle block, as well as the arc-shaped groove of the clamping block and the arc-shaped connecting groove of the clamping block, form a double-layer fit. Combined with the driving force provided by the hydraulic push rod, it can automatically clamp irregular workpieces, replacing the multiple adjustment steps required by traditional fixtures and eliminating plating deviation problems caused by unstable clamping, thus achieving rapid and precise positioning. The rotating chassis and rotating motor work in tandem, along with the sliding frame moving along the groove, to drive the brush head to rotate with the workpiece for omnidirectional coverage. Simultaneously, the through-type design of the brush solution nozzle and injection port allows for simultaneous replenishment of plating solution. This overcomes the uneven plating and low efficiency problems that easily occur with manual operation, ensuring stable and consistent electroplating quality. The telescopic adjustment of the telescopic rod and the anti-slip design of the anti-slip pads together form a simple operating system. Combined with the modular structural layout, a single person can complete workpiece clamping and parameter setting, reducing the operator's workload and allowing them to focus more on core process steps. The entire device is suitable for processing small batches of multi-specification workpieces, achieving full-process optimization from workpiece positioning to plating completion, effectively improving the efficiency and precision of electroplating operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick positioning fixture for electroplating includes a base. Fixed supports are fixedly mounted on both sides of the upper surface of the base. A rotating base is rotatably mounted on each of the two fixed supports. A rotating motor is fixedly mounted on the outer side of one of the fixed supports. The output end of the rotating motor is fixedly connected to the rotating base on the corresponding side. Multiple chuck mounting seats are fixedly arranged in a circular array on each of the two rotating bases. A hydraulic push rod is fixedly mounted on each chuck mounting seat. The telescopic end of each hydraulic push rod is fixedly connected to a movable clamping block mounting seat. Each movable clamping block mounting seat has an arc-shaped guide groove, and each arc-shaped guide groove is slidably connected to a central... Intermediate connecting blocks, each of the intermediate connecting blocks has an arc-shaped connecting groove, each of the intermediate connecting blocks has an arc-shaped connecting groove that is engaged in an arc-shaped guide groove, each of the intermediate connecting blocks has an arc-shaped clamping groove, each of the clamping grooves has a slidably connected clamping block, each clamping block has an arc-shaped connecting groove, each of the clamping grooves has an engaged in an arc-shaped clamping groove, each of the bases has sliding grooves on both sides, each of the two sliding grooves has a slider that is slidably arranged in a slider, each of the two sliders is fixedly connected to a sliding frame, each of the sliding frames has a telescopic rod fixedly arranged on both sides, and each of the telescopic rods has a fixedly connected telescopic end to a brush head;

This ensures that the workpiece can rotate at a uniform speed during the electroplating process to achieve all-around plating. Hydraulic push rods are fixed to the chuck mounting seats arranged in a circular array on the rotating chassis. The movable clamping block mounting seat connected to the telescopic end of the hydraulic push rod has an arc-shaped guide groove, which slides and engages with the arc-shaped connecting groove of the middle block of the intermediate connecting block. The arc-shaped groove of the clamping block of the intermediate connecting block then slides and engages with the arc-shaped connecting groove of the clamping block, forming a double-layer arc-shaped fitting structure. Under the driving force of the hydraulic push rod, it can adaptively conform to the surface of workpieces of different shapes, achieving… This new fast and precise clamping system solves the problems of cumbersome positioning and poor adaptability of traditional clamps for irregular workpieces. The sliding grooves on both sides of the base cooperate with the slider at the bottom of the sliding frame to adjust the lateral position of the sliding frame. The telescopic rods on both sides of the sliding frame drive the brush head to flexibly adjust the distance between itself and the workpiece, so that the brush head can be accurately aligned with the area to be plated. Together with the rotating workpiece, it completes a uniform plating layer. This collaborative structure eliminates the problems of plating deviation caused by unstable clamping and low efficiency of manual adjustment in traditional manual operation. It can adapt to various specifications of workpieces without frequent clamping changes, simplifying the operation process while ensuring the accuracy and efficiency of electroplating. It provides efficient and stable positioning and operation support for electroplating of small batches of multi-specification workpieces.

[0008] Furthermore, an anti-slip pad layer is fixedly provided on the side of the clamping block facing the clamping center;

[0009] By using the above technical solution, an anti-slip pad layer is fixedly installed on the side of the clamping block facing the clamping center. By utilizing the elastic deformation and surface friction characteristics of the anti-slip pad layer, a tight and non-slip contact can be formed between the clamping block and the workpiece surface.

[0010] Furthermore, an electrobrush liquid nozzle is fixedly installed on the top of the sliding frame;

[0011] The above technical solution allows for the precise delivery of brush fluid to the brush head working area by fixing a brush fluid nozzle on the top of the sliding frame. This nozzle moves synchronously with the sliding frame along the slide groove, and, in conjunction with the workpiece rotation driven by the rotating chassis, the brush fluid can be accurately delivered.

[0012] Furthermore, the top of the sliding frame is provided with an electrobrush liquid injection port, which is connected to the electrobrush liquid nozzle;

[0013] By using the above technical solution, a convenient brush liquid replenishment channel is constructed by opening a brush liquid injection port on the top of the sliding frame and connecting it to the brush liquid nozzle. Operators can replenish the brush liquid at any time through the injection port without disassembling or moving the sliding frame, thus avoiding interruption of the brush plating operation due to replenishment operations and ensuring the continuity of the process.

[0014] Furthermore, four support legs are fixedly installed at the bottom of the base;

[0015] By using the above technical solution, four support legs are fixedly installed at the bottom of the base to form a symmetrically distributed stable support structure, which can evenly distribute the weight of the entire fixture and the load generated during operation to the support surface, ensuring positioning accuracy and operational safety during the electroplating process.

[0026] Reference Figure 1 , Figure 3 , Figure 5 This utility model provides a specific implementation method:

[0027] A quick positioning fixture for electroplating includes a base 1. Fixed supports 14 are fixedly mounted on both sides of the upper surface of the base 1. A rotating base 12 is rotatably mounted on each of the two fixed supports 14. A rotating motor 13 is fixedly mounted on the outer side of one of the fixed supports 14. The output end of the rotating motor 13 is fixedly connected to the rotating base 12 on the corresponding side. Multiple chuck mounting seats 11 are fixedly arranged in a circular array on each of the two rotating bases 12. A hydraulic push rod 10 is fixedly mounted on each chuck mounting seat 11. The telescopic end of each hydraulic push rod 10 is fixedly connected to a movable clamping block mounting seat 15. Each movable clamping block mounting seat 15 has an arc-shaped guide groove 16. Each arc-shaped guide groove 16 is slidably connected to an intermediate connecting block 22. Each intermediate connecting block 22 has an arc-shaped connecting groove 17, which is engaged within an arc-shaped guide groove 16. Each intermediate connecting block 22 has an arc-shaped clamping groove 21, and a clamping block 19 is slidably connected within each arc-shaped clamping groove 21. Each clamping block 19 has an arc-shaped clamping groove 18, which is engaged within the arc-shaped clamping groove 21. The base 1 has sliding grooves 5 on both sides, and sliders 4 are slidably mounted within each of the two sliding grooves 5. Both sliders 4 are fixedly connected to a sliding frame 3. Telescopic rods 6 are fixedly mounted on both sides of the sliding frame 3, and the telescopic ends of both telescopic rods 6 are fixedly connected to brush heads 7. The base 1 is supported by fixed brackets 14 on both sides of its upper surface. A rotating chassis 12, driven by a rotating motor 13 located on the outer side of a fixed bracket 14, forms a rotating drive structure for the workpiece. This ensures that the workpiece rotates at a uniform speed during the electroplating process to achieve all-around plating. Hydraulic push rods 10 are fixed to chuck mounting seats 11 arranged in a circular array on the rotating chassis 12. The movable clamping block mounting seat 15, connected to the telescopic end of the hydraulic push rod 10, has an arc-shaped guide groove 16 that slides into the arc-shaped connecting groove 17 of the intermediate connecting block 22. The arc-shaped groove 21 of the intermediate connecting block 22 then slides into the arc-shaped connecting groove 18 of the clamping block 19, forming a double-layer arc-shaped fitting structure. Under the driving force of the hydraulic push rod 10, it can adaptively conform to the surface of workpieces of different shapes, achieving… This fast and precise clamping system solves the problems of cumbersome positioning and poor adaptability of traditional clamps for irregular workpieces. The sliding grooves 5 on both sides of the base 1 slide in conjunction with the sliders 4 at the bottom of the sliding frame 3, enabling the lateral position adjustment of the sliding frame 3.

It provides efficient and stable positioning and operation support for electroplating of small batches of multi-specification workpieces.

[0028] Reference Figure 1 , Figure 2, Figure 4 This utility model provides another specific embodiment:

[0029] An anti-slip pad 20 is fixedly installed on the side of the clamping block 19 facing the clamping center. By fixing the anti-slip pad 20 on the side of the clamping block 19 facing the clamping center, a tight anti-slip contact can be formed between the clamping block 19 and the workpiece surface by utilizing the elastic deformation and surface friction characteristics of the anti-slip pad 20. An electrobrush liquid nozzle 8 is fixedly installed on the top of the sliding frame 3. By fixing the electrobrush liquid nozzle 8 on the top of the sliding frame 3, the nozzle can move synchronously with the sliding frame 3 along the slide groove 5. In conjunction with the rotation of the workpiece driven by the rotating base 12, the electrobrush liquid can be accurately delivered to the working area of ​​the brush head 7. An electrobrush liquid injection port 9 is opened on the top of the sliding frame 3. The liquid injection port 9 is connected to the brush liquid nozzle 8. By opening the brush liquid injection port 9 on the top of the sliding frame 3 and connecting it to the brush liquid nozzle 8, a convenient brush liquid replenishment channel is constructed. Operators can replenish the brush liquid at any time through the injection port without disassembling or moving the sliding frame 3, avoiding interruption of the brush plating operation due to replenishment operation and ensuring the continuity of the process. Four support legs 2 are fixedly set at the bottom of the base 1. By fixing four support legs 2 at the bottom of the base 1, a symmetrically distributed stable support structure is formed, which can evenly distribute the weight of the entire fixture and the load generated during operation to the support surface, ensuring positioning accuracy and operational safety during the brush plating process.

[0030] Working principle: The operator first places the workpiece to be electroplated stably between the opposing clamping blocks 19 on both sides of the base 1. The base 1 is stably supported on the work platform by the bottom support legs 2 to ensure the stability of the entire device. Then, the hydraulic push rod 10 is activated. The telescopic end of the hydraulic push rod 10 pushes the movable clamping block mounting seat 15 to move towards the workpiece. At this time, the intermediate connecting block 22 slides adaptively along the arc-shaped guide groove 16 on the movable clamping block mounting seat 15 through its own intermediate block arc-shaped connecting groove 17. At the same time, the clamping blocks 19 slide through their own... The clamping block arc-shaped connecting groove 18 slides synchronously along the clamping block arc-shaped groove 21 on the middle connecting block 22, so that the clamping blocks 19 on both sides can automatically adjust their angles according to the outline of the workpiece until they are completely in contact with the workpiece surface. The anti-slip pad layer 20 on the inner side of the clamping block 19 is in close contact with the workpiece surface, increasing the friction to prevent the workpiece from sliding or shifting in subsequent operations, thus completing the stable fixation of the workpiece. After the workpiece is fixed, the rotating motor 13 is started. The output end of the rotating motor 13 drives the rotating chassis 12 to rotate smoothly on the fixed bracket 14. The workpiece is clamped on the clamping structure connected to the chuck mounting base 11 of the rotating base 12 on both sides. Therefore, the workpiece rotates synchronously with the rotating base 12, providing a basis for all-round electroplating. The operator pushes the sliding frame 3, and the slider 4 at the bottom of the sliding frame 3 slides along the sliding grooves 5 on both sides of the base 1 to adjust the lateral position of the sliding frame 3, so that the electroplating head 7 and the electroplating liquid nozzle 8 mounted on the sliding frame 3 are aligned with the area of ​​the workpiece that needs to be plated. Then, the telescopic rod 6 is controlled to extend and retract, and the end of the telescopic rod 6 drives the electroplating head 7 to move closer to the surface of the workpiece. Until the brush head 7 maintains a suitable working distance from the workpiece surface, the brushing solution is injected through the brushing solution inlet 9. The brushing solution is then transported through an internal passage to the brushing solution nozzle 8, and evenly sprayed from the nozzle 8 onto the workpiece surface to be plated. As the workpiece continues to rotate, the brush head 7 performs the electroplating operation on the workpiece surface. During this process, the position of the sliding frame 3 and the extension amount of the telescopic rod 6 can be adjusted to ensure that the brush head 7 always maintains good contact with the workpiece surface, achieving uniform and precise plating processing until the electroplating operation of the entire workpiece is completed.
