Description

Technical Field

[0001] This utility model relates to the field of electroplating process equipment, and more specifically, to a highly stable electroplating workpiece hook clamp. Background Technology

[0002] Electroplating is a process of depositing a metal or alloy layer on a metal surface using the principle of electrolysis. It is widely used in fields such as anti-oxidation, wear resistance, conductivity, and decoration. During the electroplating process, the workpiece needs to be fixed by a fixture and immersed in the electrolyte. The stability of the fixture directly affects the uniformity of the coating, production efficiency, and equipment lifespan.

[0003] In electroplating production, workpieces of various sizes and shapes are encountered. Existing hook clamps are mostly fixed structures or have a narrow range of applications. When dealing with different workpieces, it is often necessary to change the entire set of clamps. This not only increases the company's equipment purchase costs but also leads to extended production preparation time, as each clamp change requires debugging and installation, which seriously affects production efficiency.

[0004] During the electroplating process, factors such as electrolyte flow, mechanical vibration, and uneven weight distribution of the workpiece can all cause the workpiece to shake on the hook clamp. Workpiece shaking will cause uneven current distribution, which in turn will lead to uneven plating thickness, with some areas being too thick or too thin, thus affecting the electroplating quality.

[0005] Therefore, we have made improvements to this and proposed a highly stable hook fixture for electroplated workpieces. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a highly stable electroplated workpiece hook clamp, solving the problems mentioned in the background art.

[0008] A high-stability hook fixture for electroplated workpieces is developed to solve the above problems.

[0009] The application is as follows:

[0010] The device includes a fixing component, which has two limiting rods fixedly installed inside. Both ends of the limiting rods are slidably connected to sliding rods. A connecting rod is fixedly installed on the lower surface of the sliding rod. A clamping plate is provided on one side of the connecting rod, and a connecting mechanism is provided between the clamping plate and the connecting rod.

[0011] The connecting mechanism includes a fixed frame, which is fixedly installed on the back of the clamping plate. One end of the connecting rod is engaged with the fixed frame, and the connecting rod and the clamping plate form an engaging structure.

[0012] As a preferred technical solution of this application, holes are provided on both sides of the fixed frame, and a locking block is slidably connected to both sides of one end of the connecting rod, and the locking block and the hole are connected by a locking connection.

[0013] As a preferred technical solution of this application, both sides of the connecting rod are provided with sliding grooves, and a limiting block is slidably connected inside the sliding groove. The locking block is fixedly connected to the limiting block, and a spring is fixedly installed between one side surface of the limiting block and the inner wall of the sliding groove.

[0014] As a preferred technical solution of this application, an installation rod is fixedly installed on one side surface of the connecting rod, and a support rod is rotatably connected to one end of the installation rod. A lifting component is provided on the upper side of the two support rods, and the top ends of the two support rods are rotatably connected to the inside of the lifting component on both sides.

[0015] As a preferred technical solution of this application, a hydraulic rod is fixedly installed on the upper surface of the fixing member, and the telescopic end of the lower side of the hydraulic rod is fixedly connected to the lifting member.

[0016] As a preferred technical solution of this application, a fixing frame is fixedly installed on the upper surface of the fixing member, and a hook is rotatably connected to the upper surface of the fixing frame.

[0017] As a preferred technical solution of this application, triangular blocks are fixedly installed on both sides of the top of the hook.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] 1. Through the use of the connecting mechanism, the clamping plate and the connecting rod are connected by a snap-fit ​​structure. The snap-fit ​​block can flexibly engage with the hole in the fixed frame under the action of the spring, which facilitates quick disassembly and replacement of the clamping plate. For workpieces of different sizes and shapes, there is no need to replace the entire set of fixtures; only the appropriate clamping plate needs to be replaced. This can reduce the equipment purchase cost for enterprises, save the time of frequent debugging and installation, greatly shorten the production preparation cycle, and improve production efficiency.

[0021] 2. The hook clamp enhances stability through the coordinated action of a limiting rod, a support rod, and a hydraulic rod. The limiting rod restricts the horizontal sway of the sliding rod, the support rod is connected to the connecting rod and the lifting component, and the hydraulic rod adjusts the support angle to provide stable support for the clamping plate. Under the influence of various factors, it can effectively reduce workpiece sway, ensure uniform current distribution, make the coating thickness uniform, and improve the electroplating quality.

[0033] To address the technical problems in the background section, the following highly stable electroplated workpiece hook fixture is provided:

[0034] Combination Figure 1 - Figure 4 As shown, the present invention provides a high-stability electroplating workpiece hook clamp, including a fixing member 1. Two limiting rods 2 are fixedly installed inside the fixing member 1, and sliding rods 3 are slidably connected to the outer ends of both ends of the limiting rods 2. A connecting rod 4 is fixedly installed on the lower surface of the sliding rod 3, and a clamping plate 5 is provided on one side of the connecting rod 4. A connecting mechanism 6 is provided between the clamping plate 5 and the connecting rod 4. The connecting mechanism 6 includes a fixing frame 601, and the fixing frame 601 is fixedly installed on the back of the clamping plate 5. One end of the connecting rod 4 is engaged with the fixing frame 601, and the connecting rod 4 and the clamping plate 5 form an engaging structure.

[0035] In this embodiment: the fixing member 1 serves as a basic support, and its two internal limiting rods 2 are slidably connected to the sliding rod 3, which can effectively limit the horizontal swaying of the sliding rod 3. A clamping plate 5 is provided on one side of the connecting rod 4 connected to the lower part of the sliding rod 3, and the two are connected by a connecting mechanism 6. In this mechanism, the fixing frame 601 is fixed to the back of the clamping plate 5 and engages with the connecting rod 4, which allows for quick disassembly and replacement of the clamping plate 5 or the fixture to adapt to different workpieces and improve practicality.

[0036] In a preferred embodiment, holes 603 are provided on both sides of the fixed frame 601, and a locking block 602 is slidably connected to both sides of one end of the connecting rod 4, and the locking block 602 and the hole 603 are connected by a snap-fit ​​connection.

[0037] In this embodiment, the holes 603 on both sides of the fixed frame 601 are perfectly matched with the locking blocks 602 that slide on both sides of one end of the connecting rod 4, and the two are connected by a snap-fit ​​method. This design makes the installation and removal of the clamping plate 5 simpler and faster. The operation can be easily completed by simply pushing the locking block 602 to separate or engage with the hole 603, which greatly improves work efficiency.

[0038] In a preferred embodiment, both sides of the connecting rod 4 are provided with sliding grooves 604, and a limiting block 605 is slidably connected inside the sliding groove 604. The locking block 602 is fixedly connected to the limiting block 605, and a spring 606 is fixedly installed between one side surface of the limiting block 605 and the inner wall of the sliding groove 604.

[0039] In this embodiment: by setting a limiting block 605, the locking block 602 can be limited to prevent it from sliding out of the slide groove 604. By setting a spring 606, the limiting block 605 and the locking block 602 can be pressed against each other by the elastic force of the spring 606, so that the locking block 602 is engaged with the hole 603 to fix the clamping plate 5. When it is necessary to replace different clamping plates 5 or clamps, the locking blocks 602 on both sides can be pressed. The locking blocks 602 drive the limiting block 605 to move in the slide groove 604 and squeeze the spring 606, so that the locking block 602 is not engaged with the hole 603, which facilitates the disassembly operation.

[0040] In a preferred embodiment, a mounting rod 7 is fixedly installed on one side surface of the connecting rod 4, and a support rod 8 is rotatably connected to the inside of one end of the mounting rod 7. A lifting member 9 is provided on the upper side of the two support rods 8, and the top ends of the two support rods 8 are rotatably connected to the inside of the lifting member 9 on both sides.

[0041] In this embodiment: the lifting member 9 can drive the support rods 8 on both sides to rotate as the lifting member 9 rises. Therefore, during the rising process of the lifting member 9, the bottom end of the support rod 8 will move closer to the mounting rods 7 on both sides, generating an inward pulling force. This pulling force is transmitted to the connecting rod 4 through the mounting rod 7, which in turn drives the connecting rod 4 and the clamping plate 5 connected to it to move towards the center, ultimately achieving precise clamping of the workpiece. When the lifting member 9 descends, it can release the workpiece.

[0042] In a preferred embodiment, a hydraulic rod 10 is fixedly installed on the upper surface of the fixing member 1, and the telescopic end of the lower side of the hydraulic rod 10 is fixedly connected to the lifting member 9.

[0043] In this embodiment: the telescopic end of the lower side of the hydraulic rod 10 is tightly fixedly connected to the lifting component 9. When the hydraulic rod 10 starts working, its telescopic end can accurately and stably drive the lifting component 9 to move up and down. Then, through the linkage structure of the lifting component 9, the support rod 8, and the mounting rod 7, the connecting rods 4 on both sides move synchronously towards or away from each other, and finally drive the clamping plate 5 to achieve stable clamping.

[0044] In a preferred embodiment, a fixing frame 11 is fixedly mounted on the upper surface of the fixing member 1, and a hook 12 is rotatably connected to the upper surface of the fixing frame 11. Triangular blocks 1201 are fixedly mounted on both sides of the top of the hook 12.

[0045] In this embodiment: the fixing frame 11, which is stably set on the upper surface of the fixing member 1, provides a reliable installation base for the hook 12. The hook 12, which is rotatably connected to the upper surface of the fixing frame 11, allows the hook 12 to be adjusted according to actual needs, and can be conveniently and quickly hung on different positions or equipment, thereby enhancing the applicability and flexibility of the entire electroplating fixture.

[0046] The triangular blocks 1201 on both sides play a key limiting role. They can effectively constrain the rotation range of the hook 12 and prevent the hook 12 from rotating too much due to external force or its own weight. This greatly improves the stability of the hook 12 in the hanging state and ensures that the entire electroplating fixture can remain stable during the electroplating process.

[0047] Specifically, the working principle of this solution is as follows:

[0048] When this high-stability electroplating workpiece hook clamp is in operation, the fixing part 1 serves as the basic support, and its internal limiting rod 2 is slidably connected to the sliding rod 3, limiting the horizontal swaying of the sliding rod 3. When the hydraulic rod 10 is activated, its lower telescopic end drives the lifting part 9 to rise and fall. When the lifting part 9 rises and falls, the force is transmitted to the connecting rod 4 through the mounting rod 7 via the support rod 8 rotatably connected to it, so that the two connecting rods 4 on both sides move synchronously towards or away from each other, thereby driving the clamping plate 5 to stably clamp or release the workpiece.

[0049] The clamping plate 5 and the connecting rod 4 are connected by the connecting mechanism 6. The fixing frame 601 is fixed to the back of the clamping plate 5, and one end of the connecting rod 4 is engaged with the fixing frame 601. The locking block 602 engages with the hole 603 on the fixing frame 601. The limiting block 605 limits the locking block 602 in the slide groove 604. The spring 606 provides elastic force to make the locking block 602 tightly engage with the hole 603, fixing the clamping plate 5. Pressing the locking block 602 can drive the limiting block 605 to squeeze the spring 606, causing the locking block 602 to disengage from the hole 603, making it convenient to replace the clamping plate 5. The hook 12 on the fixing bracket 11 on the upper surface of the fixing part 1 can rotate flexibly, making it convenient to hang in different positions. The triangular blocks 1201 on both sides of its top can effectively limit the hook 12 to prevent large rotation, ensuring that the fixture is stable and reliable during the electroplating process.

[0050] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0051] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
