[0057] This embodiment also discloses an application of a slider-type adjustable fixture structure, including a slider-type adjustable fixture structure applied to workpiece processing equipment. The slider-type adjustable fixture structure in this embodiment is capable of processing workpieces of different sizes and shapes. In this embodiment, the fixture structure is applied to processing bearing caps of different sizes.

[0058] Among them, a method for applying a slider-type adjustable clamp structure includes the following steps:

[0059] Step 1: After the milling fixture 1 clamps the side surface of the workpiece, the processing device performs rough milling on the bottom surface of the workpiece;

[0060] Step 2: The turning fixture clamps the upper and lower end surfaces of the workpiece, and the processing device turns the side surfaces of the workpiece;

[0061] Step 3: The milling fixture 1 clamps the side surface of the workpiece after turning, and the processing device performs precision milling on the bottom surface of the workpiece;

[0062] Step 4: After the drilling and milling fixture clamps the workpiece, the processing device can process the semicircular holes, tile grooves, stoppers, etc. set on the workpiece, and perform precision milling on the top surface of the workpiece.

[0063] In step 1, the milling fixture 1 clamps the side of the workpiece, ensuring that the workpiece remains stable during machining while fully exposing the bottom surface, creating conditions for subsequent processing. After the workpiece is secured, a conventional machining device is activated to perform a rough milling process on the bottom surface of the workpiece, rapidly removing a large amount of material to initially achieve a shape close to the designed dimensions, laying the foundation for the subsequent fine milling process.

[0064] In step 2, after the workpiece bottom surface is roughly milled, the workpiece is transferred to the pin turning fixture. The turning fixture 2 securely clamps the upper and lower end surfaces of the workpiece. During the turning process, the machining device moves along a predetermined trajectory, sequentially grinding the front and rear sides of the workpiece to achieve the required side dimensions and surface accuracy.

[0065] In step 3, after turning the side surfaces, the workpiece is reinstalled in the milling fixture 1. At this point, the milling fixture 1 still clamps the workpiece from the side. After securing the workpiece, the machining device performs a secondary machining operation on the workpiece bottom surface using a fine milling process. Compared to rough milling, fine milling offers higher machining accuracy. Through more sophisticated tool path planning and cutting parameter control, the flatness, dimensional accuracy, and surface finish of the bottom surface are further improved, ensuring that the final design requirements are met.

[0066] In step 4, the drilling and milling fixture uses the bottom surface of the workpiece after fine milling as the reference surface, and can accurately process the semicircular holes, tile grooves, stoppers, etc. set on the workpiece, and fine mill the top surface of the workpiece.
