[0037] Example 2

[0038] This embodiment describes a method for using a horizontal tooling for rough machining of a saddle:

[0039] I. Preparations before use

[0040] Tooling inspection: Confirm that the tooling base plate 1 is placed on the worktable of the processing equipment and is level and stable. Check the connection status of the tapered guide seat 2, adjustable floating top 3, special pressure plate assembly 4 and auxiliary rod 11 to ensure that there is no looseness, deformation or missing parts. At the same time, clean the iron filings, oil stains and other impurities from the positioning surfaces and support surfaces of the tooling to avoid affecting the positioning accuracy.

[0041] Tool preparation: Prepare a wrench that is compatible with the adjustable floating top 3 adjustment mechanism for adjusting the screw rotation, a socket or wrench that matches the special pressure plate assembly 4 for tightening the nut 43, and a dial indicator for calibrating the workpiece posture (optional) for high-precision machining scenarios.

[0042] II. Workpiece Positioning and Attitude Calibration

[0043] Preliminary placement of the workpiece: Hoist the saddle workpiece 5 to be rough-machined to the top of the fixture, so that the workpiece positioning surface is in contact with the upper surface of the tapered guide seat 2, and ensure that the bottom of the workpiece is initially supported by the adjustable floating top 3. At this time, the workpiece is in the "preliminary positioning" state, to avoid the workpiece tilting or being suspended.

[0044] Horizontal attitude adjustment: Use a wrench to turn the adjusting screw of the adjustable floating top 3 to adjust it in the horizontal direction, and push the support surface of the adjustable floating top 3 to fine adjust the horizontal position of the workpiece until the workpiece machining reference surface is parallel to the tooling base plate 1; if high-precision calibration is required, the dial indicator can be attached to the spindle of the machining equipment, with the indicator head touching the workpiece reference surface, and the spindle can be rotated to observe the dial indicator reading until the reading error is ≤0.02mm, thus completing the horizontal attitude calibration.

[0045] Vertical posture adjustment: Continue to rotate the adjusting screw of the adjustable floating top 3 to adjust in the vertical direction, raise or lower the support height of the adjustable floating top 3, adjust the vertical position of the workpiece, and make the workpiece surface to be processed match the movement trajectory of the tool of the processing equipment, such as ensuring that the hole / face to be processed is within the cutting range of the tool, and at the same time ensuring that the workpiece and the positioning surface of the tapered guide seat 2 are always in contact without separation.

[0046] III. Workpiece clamping and fixing

[0047] Pressure plate assembly: Insert the pressure plate 42 in the special pressure plate assembly 4 into the threaded rod 41 through the central through hole, adjust the position of the pressure plate 42 so that one end of the pressure plate 42 presses against the upper surface of the saddle workpiece 5 in a region with strong workpiece rigidity to avoid damaging the thin-walled parts of the workpiece, and the other end rests against the top of the auxiliary rod 11 to form a stable structure of "support at both ends and pressing in the middle".

[0048] Gradually tighten: Use a wrench to turn the fastening nut 43 clockwise. First, pre-tighten the nuts on both sides until the pressure plate is not loose. Then, tighten the nuts on both sides alternately to avoid over-tightening on one side, which may cause the workpiece to shift. Observe whether the workpiece shifts during the tightening process. If shift occurs, stop tightening, readjust the adjustable floating top 3 to calibrate the posture, and then continue until the fastening nut 43 is tightened to the specified torque, which is determined according to the material and thickness of the workpiece. It is generally 20-30 N·m. Avoid over-tightening to prevent the workpiece from deforming.

[0049] IV. Process Monitoring

[0050] Pre-processing re-inspection: Before starting the processing equipment, manually push the workpiece with slight force to confirm that the workpiece does not shake; check again the fit between the pressure plate 42 and the workpiece and the auxiliary rod 11, and whether the adjustable floating top 3 adjustment mechanism has a locking part containing a positioning pin. The positioning pin needs to be inserted to fix the adjustment position to ensure that the tooling and the workpiece are firmly connected.

[0051] Observation during processing: During rough machining, observe the cutting status in real time through the equipment observation window or monitoring system, paying close attention to whether the workpiece vibrates or makes abnormal noises. If any abnormality occurs, stop the equipment immediately, check the tooling clamping status and workpiece posture, and continue processing only after troubleshooting.

[0052] V. Disassembly of the workpiece after processing

[0053] Loosen the pressure plate: After processing is completed, the spindle of the equipment to be processed is completely stopped and the tool is away from the workpiece. Use a wrench to turn the fastening nut 43 counterclockwise. First loosen the nuts on both sides until the pressure plate 42 is separated from the upper surface of the workpiece, and then remove the pressure plate 42.

[0054] Workpiece hoisting: Using hoisting equipment or manually, the processed saddle workpiece 5 is moved from above the tooling according to the workpiece weight to avoid collision between the workpiece and the tapered guide seat 2 and the adjustable floating top 3.

[0055] Tooling cleaning and resetting: Clean the surface of the tooling of any residual iron filings and cutting fluid, and wipe all components clean with a cloth; adjust the adjustable floating top 3 to the initial center position for easy use next time, check whether each part is intact, and if long-term storage is required, apply anti-rust oil to the metal surface of the tooling.
