Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to a shaft-type parts clamping device for a precision electroplating machine. Background Art

[0002] The electroplating machine is a metal processing equipment that uses electrolysis to coat a thin film on the surface. Its principle is: placing an electrolyte solution containing pre-treated metal ions in an electrolytic cell, and then reducing the metal ions to metal ions through electric current, and forming a metal coating on the surface of the substrate, thereby achieving the purpose of coating processing. It is mainly composed of an electrolytic cell, a power supply, an anode, a cathode, etc.

[0003] During the electroplating process, shaft parts need to be clamped and fixed at their collars to facilitate immersion of the shaft parts in the electroplating solution. However, the clamping point is shielded by the fixture, making it impossible to electroplate, thus affecting the overall electroplating quality of the shaft parts. Utility Model Content

[0004] The utility model discloses a shaft-type component clamping device for a precision electroplating machine, aiming to solve the technical problem that the clamping position is shielded by a fixture, which leads to failure of electroplating, thereby affecting the overall electroplating quality of the shaft-type component.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The shaft-type electroplated parts are clamped and fixed by a movable rotating clamping method to avoid the situation where the outer wall of the electroplated parts is blocked due to the fixed clamping position, resulting in the inability to electroplate. The overall electroplating effect of the shaft-type electroplated parts is improved. At the same time, the device can adjust the clamping radius according to the specifications of the ring shaft of different shaft-type electroplated parts, thereby facilitating the clamping and fixing of shaft-type electroplated parts of different specifications and improving the adaptability of the device.

[0008] In a preferred solution, annular grooves are formed on the three rotating shafts, and conductive rings are fixedly connected inside the annular grooves.

[0009] By providing the conductive ring, the entire sleeve wheel is insulated, and the conductive ring can be connected to the conductive contact layer, so that the conductive contact layer can be energized.

[0011] By providing a hydraulic cylinder, the hydraulic cylinder provides a driving force for the movable seat to move, thereby achieving the purpose of adjusting the clamping range.

[0012] In a preferred solution, a power transmission seat is provided below each of the three curved frames, a vertical pole is fixedly connected to the power transmission seat, the upper ends of the vertical poles are fixedly connected between the curved frames, and a brush is fixedly connected to the side of the power transmission seat close to the rotating shaft, and the brush is in contact with the outer wall of the conductive ring; a groove is provided on the movable seat, a plug is fixedly connected to the inside of the groove, and a power transmission wire is fixedly connected to the lower end of the plug, and the other end of the transmission wire is fixedly connected to the power transmission seat.

[0013] By providing brushes and plugs, the plug is connected to the external circuit, and the brushes ensure that the current can be stably transmitted to the conductive ring during the rotation of the shaft. The setting of three brushes and the plug can effectively avoid current instability.

[0014] In a preferred embodiment, the mounting seat is provided with three circumferentially equidistant circular holes, and three circumferentially equidistant synchronous motors are fixedly connected to the mounting seat, and the output ends of the three synchronous motors are connected to the rotating shafts through couplings, and the other ends of the rotating shafts pass through the circular holes on the mounting seat and are fixedly connected to the rotating shafts on the lower side.

[0015] By providing a synchronous motor, the synchronous motor provides a driving force for rotating the rotating shaft.
