Description

Technical Field

[0001] The utility model relates to the technical field of electroplating processing, in particular to a plastic part finishing electroplating fixture. Background Art

[0002] Electroplating is a surface treatment method in which the base metal to be plated is used as the cathode in a salt solution containing the pre-plated metal. Through electrolysis, the cations of the pre-plated metal in the plating solution are deposited on the base metal surface, forming a coating. During the electroplating process, a fixture is required to hold the product in place, making it easier for the operator to perform the electroplating.

[0003] At present, existing electroplating fixtures generally clamp the product directly through claws. However, due to the low strength of plastic parts, the instantaneous clamping force during the clamping process is very likely to be excessive, causing damage to the product and affecting the subsequent electroplating effect. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and includes: a mounting frame; a telescopic cylinder, which is arranged above the mounting frame and is connected to the push plate at the bottom of the telescopic cylinder; a clamping claw, which is connected to the push plate through a connecting plate, and the top of the clamping claw is rotatably connected to the mounting frame; a fixing member, one side of the fixing member is connected to the clamping claw, and the other side of the fixing member is provided with a clamping plate; a buffer spring, which is connected between the fixing member and the clamping plate; a connecting frame, which is connected to the mounting frame at the bottom and connected to the drive motor at the top.

[0005] As a further description of the above technical solution: two rotating rods are provided on the mounting frame, and the clamping claws are rotatably connected to the rotating rods.

[0006] As a further description of the above technical solution: the four corners of the pushing plate are rotatably connected to one end of the connecting plate through a rotating shaft, and the other end of the connecting plate is rotatably connected to the clamping claw.

[0008] As a further description of the above technical solution: the connection between the connecting frame and the mounting frame is a detachable connection, and a mounting plate is provided above the driving motor.

[0009] As a further description of the above technical solution: four connecting plates and four clamping claws are provided.

[0010] The above technical solution has the following advantages or beneficial effects:

[0011] The utility model controls the telescopic cylinder to rise, which can drive the push plate to move upward, and the push plate will pull the connecting plate to move inward, pulling the clamping claw to clamp and fix the product through the clamping plate. At the moment when the clamping plate clamps the workpiece, the buffer spring will buffer and reduce shock to avoid excessive clamping force at the moment, thereby protecting the product. At the same time, by controlling the operation of the drive motor, the mounting frame can be driven to rotate, and then the workpiece clamped by the clamping plate can be driven to rotate, thus avoiding the workpiece from being in a static state for a long time, prompting it to fully contact with the electroplating solution, and improving the overall uniformity of the electroplating process.
