Description

A workpiece electroplating fixture Technical Field

[0001] This utility model relates to the field of electroplating auxiliary fixtures technology, specifically to a workpiece electroplating fixture. Background Technology

[0002] Electroplating racks vary depending on the shape of the part, the technical requirements of the plating layer, the electroplating process, and the size of the equipment; different types of racks exist for each type. For example, there are differences between automated and manual lines. Electroplating workshops typically prepare general-purpose racks suitable for various common parts, as well as specialized racks designed and manufactured specifically for certain parts. General-purpose racks come in many forms and are suitable for various processes and parts.

[0003] Existing technologies, such as the electroplating fixture for a ring-shaped workpiece with application number "201821419680.0", employ a workpiece clamping device on the main support. The inner ring of the ring-shaped workpiece can be clamped by the cooperation of two plates and springs on the workpiece clamping device. Compared with traditional hooks, the clamping force is tighter and the connection between the workpiece and the fixture is more secure. By setting two pointed tips, the contact area between the pointed tips and the workpiece is small, which is less likely to affect the electroplating quality of the workpiece. The support feet make it easy for the fixture to stand up when it is removed.

[0004] However, in actual use, the above technical solution uses plates and springs to hold the ring-shaped workpiece. When the workpiece is held in place, it needs to rub against the sides of the upper and lower pointed blocks, which will damage the workpiece. At the same time, after it is hung up, since it is not stably limited, it will collide with the main support and base during electroplating, which will also damage the workpiece. After the electroplating is completed, it still needs to rub against the sides of the upper and lower pointed blocks to bring the two plates closer together before it can be removed, which will cause friction damage to the workpiece.

[0005] Therefore, a workpiece electroplating fixture is proposed. Summary of the Invention

[0006] To address the problems existing in the prior art, this utility model provides a workpiece electroplating fixture.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A workpiece electroplating fixture includes a main rod, an integrally formed connecting plate and a connecting hook on the upper part of the main rod, a fixture frame connected to the main rod, a limiting fixture assembly for limiting the workpiece on the main rod, and a pressing member for pushing the limiting fixture assembly to support the workpiece on the fixture frame.

[0009] Furthermore, at least three are provided on the side of the main rod.

[0010] Furthermore, the limiting hanger assembly is evenly distributed on the side of the main rod, and the limiting hanger assembly includes a fixed plate, a telescopic rod, a spring, a limiting hanger plate, a first limiting baffle, a second limiting baffle, a trapezoidal block, and a protective pad.

[0011] Furthermore, the spring is sleeved on the telescopic rod, the telescopic rod is set on one side of the fixed plate, the limiting plate is connected to the telescopic end of the telescopic rod, the limiting plate is slidably set on the main rod, the trapezoidal block is set on one side of the limiting plate, and the first limiting baffle and the second limiting baffle are set on the other side of the limiting plate.

[0012] Furthermore, the protective pad is disposed on one side of the limiting plate, and the protective pad is disposed between the first limiting baffle and the second limiting baffle. The side of the limiting plate away from the limiting plate is designed with an arc shape.

[0013] Furthermore, the extrusion component includes an electric telescopic rod, an extrusion plate, and a connecting rod. The electric telescopic rod is located at the bottom end of the hanger frame. The extrusion plate is connected to the telescopic end of the electric telescopic rod. The extrusion plate and the connecting rod are integrally formed in an interlocking design. The extrusion plate is in extrusion contact with the trapezoidal block.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model allows the ring-shaped workpiece to be directly hung on the limiting hanger plate by the setting of the limiting hanger assembly. The first limiting baffle and the second limiting baffle provide initial positioning. Then, under the action of the extrusion component, the ring-shaped workpiece can be extruded and limited. Therefore, during subsequent electroplating, it can prevent the workpiece from swaying due to the buoyancy of the water and colliding with the hanger and being damaged. At the same time, the protective pad can also protect the workpiece and prevent it from being damaged. Attached Figure Description

[0025] As shown in Figures 1-4, a workpiece electroplating fixture includes a main rod 1, an integrally formed connecting plate 5 and a connecting hook 6 on the upper part of the main rod 1, a fixture frame 4 connected to the main rod 1, and a limiting fixture assembly 3 for limiting the workpiece on the main rod 1. The fixture frame 4 is equipped with a pressing member 2 that pushes the limiting fixture assembly 3 to support the workpiece. Specifically, each limiting fixture assembly 3 has two limiting plates 304. The limiting fixture assembly 3 can initially limit the annular workpiece by directly hanging it on the limiting plates 304. The pressing member 2 then compresses the limiting plates 304, causing them to move away from each other, thus limiting the annular workpiece. Therefore, during subsequent electroplating immersion, the workpiece is prevented from swaying due to water buoyancy and colliding with the fixture, thus avoiding damage.

[0026] As shown in Figure 1, at least three are provided on the side of the main rod 1; specifically, the number of extrusion members 2 is also provided in a corresponding number according to the number of sides of the main rod 1.

[0027] As shown in Figures 1-3, the limiting hanger assembly 3 is evenly distributed on the side of the main rod 1. The limiting hanger assembly 3 includes a fixed plate 301, a telescopic rod 302, a spring 303, a limiting hanger 304, a first limiting baffle 305, a second limiting baffle 306, a trapezoidal block 307, and a protective pad 308.

[0028] As shown in Figures 1-3, spring 303 is sleeved on telescopic rod 302, which is located on one side of fixed plate 301. Limiting plate 304 is connected to the telescopic end of telescopic rod 302. Limiting plate 304 is slidably mounted on main rod 1. Trapezoidal block 307 is located on one side of limiting plate 304. First limiting baffle 305 and second limiting baffle 306 are located on the other side of limiting plate 304. Specifically, under the action of telescopic rod 302 and spring 303, the distance between the two limiting plates 304 is close, so it is convenient to hang the annular workpiece on the two limiting plates 304. Then, the operation of extrusion component 2 will cause the two limiting plates 304 to move away from each other, thus extruding and limiting the annular workpiece. The first limiting baffle 305 and the second limiting baffle 306 can initially limit the position of the annular workpiece to prevent it from falling.

[0029] As shown in Figures 1-3, the protective pad 308 is disposed on one side of the limiting plate 304. The protective pad 308 is disposed between the first limiting baffle 305 and the second limiting baffle 306. The side of the limiting plate 304 away from the limiting plate 304 is designed with an arc shape. Specifically, the protective pad 308 can protect the workpiece and prevent it from being damaged. The protective pad 308 can be designed to be hollow according to the usage requirements to increase the contact area with the electroplating solution.

[0030] As shown in Figure 4, the extrusion component 2 includes an electric telescopic rod 201, an extrusion plate 202, and a connecting rod 203. The electric telescopic rod 201 is located at the bottom of the hanger frame 4. The extrusion plate 202 is connected to the telescopic end of the electric telescopic rod 201. The extrusion plate 202 and the connecting rod 203 are integrally formed in an interlocking design. The extrusion plate 202 is in extrusion contact with the trapezoidal block 307. Specifically, each electric telescopic rod 201 has an independent control unit, which can individually control the distance of movement of the two limiting hanger plates 304 in each limiting hanger assembly 3. Therefore, it can limit the movement of annular workpieces of different diameters. When clamping and limiting the workpiece, the protective pad 308 has a certain buffering capacity, which can prevent the workpiece from deforming. The extension value of the electric telescopic rod 201 can be adjusted for annular workpieces of different diameters to ensure their limiting. Further details are omitted here.

[0031] In summary: Each limiting hanger assembly 3 is equipped with two limiting hanger plates 304. The limiting hanger assembly 3 can initially limit the circular workpiece. By directly hanging it on the limiting hanger plate 304, it can be initially limited. Then, the pressing member 2 can compress the limiting hanger plates 304 and make them move away from each other, thus compressing and limiting the circular workpiece. Therefore, during the subsequent electroplating and immersion, it can prevent the workpiece from swaying due to the buoyancy of the water and colliding with the hanger for damage.
