[0002] The faucet is generally formed by a casting process. After forming, the semi-finished faucet needs to be further processed by drilling and milling. When the semi-finished faucet is processed in the above process, in addition to the processing equipment, a clamp is also needed to clamp the semi-finished faucet. The existing clamp used to assist in faucet processing generally includes a pair of left and right clamping components, which can be close to each other to clamp the faucet to be processed. The existing pair of left and right clamping components are generally rigid clamping components.

[0003] In the actual production process, companies often need to process different types of faucets, but the same equipment often cannot meet the processing needs of faucets with different shapes. This leads to problems such as faucet processing occupying more equipment, more manpower, and more factory area. Summary of the invention

[0004] The present invention aims to overcome the deficiency in the prior art that the singleness of the clamp makes it impossible for the processing device to fix and process faucets of different shapes, and provides a four-axis processing device and processing method for a faucet body that can well clamp and process faucets of different shapes.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

All the telescopic columns inside the annular chucks move toward the workpiece, and fix the workpiece from all sides. After the fixing is completed, tighten the fastening bolts of the annular chucks to fix the annular chucks, and then close the safety door;

[0008] Step 2: Input the tool feeding program and the four-axis running program of the equipment on the console, and press the equipment start button after inputting;

[0009] Step 3: The control motor automatically adjusts the position of the fixture on the X-axis and Y-axis to move the workpiece to the position directly below the machining power head. After it is in place, the machining power head on the Z-axis starts to work and automatically moves down. The tool on it processes the upper end surface of the workpiece. During processing, the control motor will continuously adjust the position of the fixture on the X-axis and Y-axis to meet the requirements of the shape to be processed. After processing, the power head automatically resets;

[0011] Step 5: Control the motor to fine-tune the position of the fixture on the X-axis and Y-axis accordingly. After completion, the processing power head automatically works, and the replaced tool processes the other surfaces of the workpiece.
