Description

Technical Field

[0001] This application relates to the field of electroplating fixture technology, and in particular to a multi-row adjustable clamping fixture. Background Technology

[0002] In the field of electroplating, electroplating racks serve as important auxiliary tools, playing a crucial role in improving production efficiency and ensuring product quality. With the continuous development of industrial manufacturing, the types of workpieces to be processed are increasing, and their specifications are becoming more diverse, placing higher demands on the versatility and adaptability of electroplating racks.

[0003] In traditional electroplating processes, the method of clamping and fixing workpieces of different sizes for electroplating operations mainly relied on various sizes of electroplating racks. For workpieces of different sizes, operators could select racks of appropriate sizes to fix the workpieces, and then transfer the racks into the electroplating tank and hang them on conductive hooks for electroplating.

[0004] However, the non-adjustable nature of traditional electroplating racks presents significant drawbacks in practical applications. Because the appropriate rack can only be changed according to the size of the workpiece, frequent rack changes are necessary during processing, consuming considerable time and manpower and severely impacting production efficiency. Therefore, improvements are needed. Utility Model Content

[0005] To address the issue of limited applicability of traditional electroplating hangers, this application provides a multi-row adjustable clamping hanger.

[0006] This application provides a multi-row adjustable clamping hanger, which adopts the following technical solution:

[0007] A multi-row adjustable clamping fixture includes hooks, a first connecting rod, a second connecting rod, and a support shaft. The hooks are disposed on the first connecting rod and form a hanging engagement with a conductive hook. The support shafts are arranged in a linear array between the first and second connecting rods, with both ends of each support shaft connected to the first and second connecting rods respectively. Each support shaft is provided with a clamping assembly that forms a clamping engagement with the workpiece to be processed, and multiple clamping assemblies are arranged along the axial direction of the support shaft. Each clamping assembly includes a first clamping plate, a pad, a second clamping plate, and an adjusting bolt. The pad is fixed between the first and second clamping plates, and a clamping space for the workpiece to be processed is formed between the first and second clamping plates. The adjusting bolt is threadedly connected to the first clamping plate, and the adjusting bolt forms an abutment engagement with the workpiece to be processed within the clamping space.

[0008] By adopting the above technical solution, the hook and conductive hook are properly matched to facilitate electroplating by powering on the hanger; multiple support axes are arranged in a linear array, and multiple clamping components are set on each support axis to clamp multiple workpieces to be processed at the same time, improving electroplating efficiency; the clamping components are fixed between the first clamping plate and the second clamping plate by pads to form a clamping space, and at the same time, they are abutted against the workpieces to be processed by adjusting bolts, which can realize the clamping of workpieces of different specifications, improve the applicability of the hanger, and solve the problem of low applicability of traditional electroplating hangers.

[0009] Preferably, one end of any of the adjusting bolts that abuts against the workpiece to be processed is provided with an abutment portion for reducing the contact area between the adjusting bolt and the workpiece to be processed.

[0010] By adopting the above technical solution, the contact area between the adjusting bolt and the workpiece to be processed can be reduced, avoiding the impact of excessive contact area on the electroplating effect. It can also make the pressure applied by the adjusting bolt more concentrated and improve the clamping stability.

[0011] Preferably, any of the clamping components is adjustablely disposed on the support shaft along the axial direction of the support shaft.

[0012] By adopting the above technical solution, the clamping assembly can be flexibly adjusted along its axial direction on the support shaft, which can adapt to workpieces of different sizes and shapes, further improving the versatility and adaptability of the fixture to workpieces of different specifications, reducing the need to change the fixture due to different workpiece specifications, and improving production efficiency.

[0013] Preferably, multiple sleeves are slidably arranged on any of the support shafts corresponding to the number of clamping components. The first clamping plate, the pad, and the second clamping plate in any of the clamping components are all fixedly connected to the outer wall of the sleeve, and the sleeve is threaded with a fixing bolt that forms an abutment fit with the support shaft.

[0014] By adopting the above technical solution, the sleeve that slides on the support shaft is used to make the clamping components move axially along the support shaft with the sleeve. The position of each clamping component can be flexibly adjusted according to the size and shape of the workpiece to be processed, which improves the applicability of the fixture. At the same time, the fixing bolts form an abutment fit with the support shaft, which can fix the clamping components after the position is determined, ensuring stable clamping of the workpiece during the electroplating process.

[0015] Preferably, any of the support shafts is adjustablely disposed between the first connecting rod and the second connecting rod along its linear array direction.

[0016] By adopting the above technical solution, the multi-row adjustable clamping fixture can adjust the position of the support shaft between the first connecting rod and the second connecting rod according to the different widths of the workpiece to be processed, thereby adjusting the distance between adjacent support shafts. This makes the fixture suitable for workpieces of different specifications, improving the applicability of the fixture, avoiding frequent fixture changes, saving time and manpower, and improving production efficiency.

[0017] Preferably, one end of any of the support shafts near the first connecting rod is fixedly connected to a first buckle that forms an embedded sliding engagement with the first connecting rod, and the first buckle is provided with a first positioning bolt. The first connecting rod has a first adjusting groove that forms a sliding engagement with the first positioning bolt, and the first positioning bolt passes through the first buckle and the first adjusting groove and is threadedly connected to a first positioning nut; one end of any of the support shafts near the second connecting rod is fixedly connected to a second buckle that forms an embedded sliding engagement with the second connecting rod, and the second buckle is provided with a second positioning bolt. The second connecting rod has a second adjusting groove that forms a sliding engagement with the second positioning bolt, and the second positioning bolt passes through the second buckle and the second adjusting groove and is threadedly connected to a second positioning nut.

[0018] By adopting the above technical solution, the support shaft is provided with a first buckle and a second buckle at both ends, which are respectively fitted with the first connecting rod and the second connecting rod in a sliding engagement. The first positioning bolt and the second positioning bolt are respectively combined with the corresponding first positioning nut and the second positioning nut, so that the position of the support shaft in the linear array direction can be adjusted, thereby adjusting the distance between adjacent support shafts, thus adapting to workpieces of different specifications, improving the applicability of the fixture, reducing the frequency of fixture replacement, and thus improving production efficiency.

[0019] Preferably, the hook is detachably connected to the first connecting rod.

[0020] By adopting the above technical solution, it is convenient to replace and maintain the hooks, which improves the flexibility of the hanging fixture. At the same time, it is not necessary to replace the entire hanging fixture when the hook is damaged, thus reducing the cost of use.

[0021] Preferably, the second connecting rod is provided with a support foot.

[0022] By adopting the above technical solution, the support feet can provide stable support for the fixture, making the fixture more stable and facilitating the clamping of the workpiece to be processed and subsequent operations.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By using the adjusting bolt to connect with the first clamping plate by thread, the adjusting bolt abuts against the workpiece to be processed, which allows for flexible control of the clamping force, adapts to different specifications of workpieces to be processed, improves the applicability of the fixture, avoids frequent fixture changes, saves time and manpower, and improves production efficiency.

[0025] 2. The clamping components can be adjusted along the support shaft axially, and the position of each clamping component can be reasonably adjusted according to the size of the workpiece to be processed, so that the fixture can better adapt to workpieces of different specifications;

[0026] 3. The support shaft can be adjusted along the linear array direction between the first connecting rod and the second connecting rod, and the spacing between the support shafts can be changed as needed, so that the fixture can be applied to workpieces of different widths, thus enhancing the applicability of the fixture.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0032] Embodiment 1 of this application discloses a multi-row adjustable clamping hanger.

[0033] Reference Figure 1 and Figure 2A multi-row adjustable clamping fixture includes a hook 1, a first connecting rod 2, a second connecting rod 3, and a support shaft 4. The hook 1 is disposed on the first connecting rod 2 and forms a hanging engagement with a conductive hook. The support shaft 4 is arranged in a linear array between the first connecting rod 2 and the second connecting rod 3, and both ends of any support shaft 4 are respectively fixedly connected to the first connecting rod 2 and the second connecting rod 3 by welding. Each support shaft 4 is provided with a clamping assembly 5 that forms a clamping engagement with the workpiece to be processed, and multiple clamping assemblies 5 are arranged along the axial direction of the support shaft 4. In this embodiment, eight clamping assemblies 5 are provided. The holding assembly 5 includes a first clamping plate 51, a pad 52, a second clamping plate 53, and an adjusting bolt 54. The pad 52 is fixed between the first clamping plate 51 and the second clamping plate 53 by welding. The first clamping plate 51, the pad 52, and the second clamping plate 53 are all fixedly connected to the support shaft 4 by welding. The first clamping plate 51 and the second clamping plate 53 form a clamping space for the workpiece to be processed. There are two adjusting bolts 54. The two adjusting bolts 54 are located on both sides of the support shaft 4 and are threadedly connected to the first clamping plate 51. Each adjusting bolt 54 forms an abutment fit with the workpiece to be processed within the clamping space.

[0034] In practical use, the hook 1 and the conductive hook form a hanging fit to facilitate electroplating of the workpiece after the fixture is powered on. Multiple support shafts 4 are arranged in a linear array between the first connecting rod 2 and the second connecting rod 3, and multiple clamping components 5 are arranged along the axial direction on any support shaft 4, so that the fixture can fix multiple workpieces to be processed at the same time, thereby improving the electroplating efficiency of the workpieces to be processed. The clamping components 5 are fixed between the first clamping plate 51 and the second clamping plate 53 by the pad 52 to form a clamping space, which facilitates fixing the workpieces to be processed. Two adjusting bolts 54 are threaded to the first clamping plate 51 on both sides of the support shaft 4, and any adjusting bolt 54 forms an abutment fit with the workpiece to be processed in the clamping space, so that any adjusting component can clamp two workpieces to be processed at the same time, further improving the electroplating efficiency. At the same time, the clamping range of the clamping space is adjustable, which improves the applicability of the fixture and solves the problem of low applicability of traditional electroplating fixtures.

[0035] Reference Figure 1 and Figure 2 Each of the adjusting bolts 54 has an abutting portion 541 at one end that abuts against the workpiece to be processed, which is provided by turning to reduce the contact area between the adjusting bolt 54 and the workpiece. In this embodiment, the abutting portion 541 is arranged in a "bullet head" shape. In actual use, the abutting portion 541 can reduce the contact area between the adjusting bolt 54 and the workpiece to be processed, thereby reducing the impact on the overall electroplating effect of the workpiece to be processed. At the same time, the "bullet head" shape of the abutting portion 541 makes the pressure applied by the adjusting bolt 54 relatively concentrated, thereby improving the stability of clamping.

[0036] Reference Figure 1 The hook 1 is detachably connected to the first connecting rod 2. In this embodiment, the end of the hook 1 near the first connecting rod 2 is fixedly connected to the connecting shaft 11 by welding. A collar 111 is slidably provided on the connecting shaft 11, and a connecting bolt 112 that abuts against the connecting shaft 11 is threaded onto the collar 111. A fixing rod 21 is fixedly connected to the first connecting rod 2 by welding. There are two fixing rods 21, and the ends of the two fixing rods 21 away from the first connecting rod 2 are fixedly connected to the collar 111 on both sides by welding. In actual use, the hook 1 is detachable by combining the collar 111 and the connecting bolt 112, which facilitates the maintenance and replacement of the hook 1. At the same time, partial replacement can be performed when the hook 1 is damaged, thereby reducing maintenance costs.

[0037] Reference Figure 1 The second connecting rod 3 is provided with a support foot 7. In this embodiment, there are two support feet 7, and the two support feet 7 are respectively fixedly connected to the two ends of the second connecting rod 3 in the axial direction by welding. In actual use, the support feet 7 can provide stable support for the hanger, so that the hanger can be placed stably, thereby facilitating the clamping of the workpiece to be processed and subsequent electroplating operations.

[0038] The implementation principle of Embodiment 1 of this application is as follows: the hook 1 and the conductive hook form a hanging cooperation to facilitate electroplating of the workpiece to be processed after the hanger is energized. The hook 1 is detachable through the sliding cooperation between the connecting shaft 11 and the collar 111 and the abutment of the connecting bolt 112, which facilitates maintenance and replacement and reduces costs. The support shaft 4 is arranged in a linear array between the first connecting rod 2 and the second connecting rod 3, and multiple clamping components 5 are axially arranged on each support shaft 4, which significantly increases the number of workpieces to be processed that can be fixed at the same time and improves electroplating efficiency. The support feet 7 set at both ends of the second connecting rod 3 provide stable support for the hanger, which facilitates workpiece clamping and subsequent electroplating operations.

[0039] The clamping assembly 5 is fixed between the first clamping plate 51 and the second clamping plate by the pad block 52 to form a clamping space. The adjusting bolt 54, which is threaded to the first clamping plate 51, abuts against the workpiece to be processed, realizing adjustable clamping to adapt to workpieces of different specifications and improve the applicability of the fixture. The abutting part 541 at the end of the adjusting bolt 54 is set in a "bullet head" shape, which can reduce the contact area between the adjusting bolt 54 and the workpiece to be processed, thereby reducing the impact on the overall electroplating effect and enhancing the clamping stability by concentrating pressure.

[0040] This application also discloses a multi-row adjustable clamping hanger in embodiment two, which differs from embodiment one in that:

[0041] Reference Figure 3Each of the clamping components 5 is adjustablely mounted on the support shaft 4 along its axial direction. In this embodiment, eight sleeves 6 are slidably mounted on the support shaft 4 corresponding to the number of clamping components 5. The first clamping plate 51, the pad 52, and the second clamping plate 53 in each of the clamping components 5 are all fixedly connected to the outer wall of the sleeve 6 by welding. The sleeve 6 is threaded with a fixing bolt 61 that abuts against the support shaft 4. In actual use, by fixing the clamping components 5 to the slidably mounted sleeves 6, the position of each clamping component 5 can be flexibly adjusted according to the size and shape of the workpiece to be processed, which improves the applicability of the fixture. At the same time, after the clamping components 5 are adjusted to the appropriate position, they can be fixed by abutting against the support shaft 4 with the fixing bolt 61, which ensures the stability of clamping during the electroplating process.

[0042] Reference Figure 3 Any of the support shafts 4 can be adjusted along its linear array direction between the first connecting rod 2 and the second connecting rod 3. In this embodiment, one end of any support shaft 4 near the first connecting rod 2 is fixedly connected by welding to a first buckle 41 that forms an embedded sliding fit with the first connecting rod 2. The first buckle 41 is provided with a first positioning bolt 42, and there are two first positioning bolts 42. The first connecting rod 2 is provided with a first adjusting groove 22 that forms a sliding fit with the first positioning bolt 42, and any one of the first positioning bolts 42 passes through the first buckle 41 to... The first adjusting groove 22 is threadedly connected to the first positioning nut 43; one end of any of the support shafts 4 near the second connecting rod 3 is fixedly connected by welding to a second buckle 44 that forms an embedded sliding fit with the second connecting rod 3. The second buckle 44 is provided with a second positioning bolt 45, and there are two second positioning bolts 45. The second connecting rod 3 is provided with a second adjusting groove 31 that forms a sliding fit with the second positioning bolt 45, and any of the second positioning bolts 45 passes through the second buckle 44 and the second adjusting groove 31 and is threadedly connected to the second positioning nut 46.

[0043] In practical use, by using the first buckle 41 and the second buckle 44 at both ends of the support shaft 4 to slide on the first connecting rod 2 and the second connecting rod 3 respectively, the position of the support shaft 4 in the linear array direction can be adjusted, thereby adjusting the distance between adjacent support shafts 4. At the same time, by using the first positioning bolt 42 in combination with the first positioning nut 43 and the second positioning bolt 45 in combination with the second positioning nut 46, the support shaft 4 can be fixed after its position is adjusted, making the hanger more suitable for workpieces of different specifications, reducing the frequency of changing the hanger, and thus improving production efficiency.

[0044] Reference Figure 3In any embodiment of this application, a screw 71 is fixedly connected to the support foot 7 by welding, and the screw 71 passes through the second adjustment groove 31 and is threadedly connected to the third positioning nut 72. In actual use, the screw 71 combined with the third positioning nut 72 can realize the detachable function of the support foot 7, which facilitates the maintenance and replacement of the support foot 7. At the same time, when adjusting the spacing of the support shaft 4 and it is necessary to remove part of the support shaft 4, the support foot 7 can be removed to avoid it blocking the sliding of the support shaft 4 on the second connecting rod 3.

[0045] The implementation principle of Embodiment 2 of this application is as follows: The clamping assembly 5 achieves axial position adjustment through the sliding of the sleeve 6 on the support shaft 4, which can be flexibly arranged according to the size and shape of the workpiece to be processed. At the same time, it is fixed by the fixing bolt 61 abutting against the support shaft 4 to ensure electroplating stability. The first buckle 41 and the second buckle 44 at both ends of the support shaft 4 form an embedded sliding fit with the first connecting rod 2 and the second connecting rod 3 respectively. The first positioning bolt 42 and the second positioning bolt 45 are respectively combined with the corresponding first positioning nut 43 and the second positioning nut 46, which can adjust the position of the support shaft 4 in the linear array direction, thereby adjusting the distance between adjacent support shafts 4, further adapting to workpieces of different specifications, reducing the frequency of fixture replacement and improving efficiency. The support foot 7 is detachable by the combination of the screw 71 and the third positioning nut 72, which is convenient for maintenance and replacement, and can avoid hindering the sliding when adjusting the spacing of the support shaft 4.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
