Turning up with a cylinder-centering fixture design flexibility


112 two 3 = hesitate cylindrical and l0 ¨ 'hole for 10 ¨'. Reference hole concentricity is not greater than 0-04. Production - the use of common tooling lathe processing, need to install multiple Central - labor-intensive, low work efficiency humble, and the degree of the axis to surgery is difficult to guarantee. For this reason, flexibility in design and manufacture of small-centering up Austria with special tooling t solve processing problems. Figure 1 State 2 cylinder profile technology and common tooling disadvantages turning up 3-centering fixture flexible structure and working principle of universal tooling with the lathe turning cylinder, is the rejection of three-jaw chuck, steady rest and activities leading to of turning. First to use three-jaw chuck and top mounted central cylinder, processing and end outside the four slots. Both sides in the rough outside the nest on the processing center rack. Then Piediao top, use the center rack central cylinder. Processing the other side of the hole and groove shape, groove within the last U-turn machining, thus turning completed. Can be seen, complete cylinder car 1;! L processing must be three clamping, and processing base continues to change, and do not coincide with the design basis, both resulting in increased labor intensity, process efficiency resulting in lower t and difficult to guarantee concentricity requirements, thus affecting the production. Centering fixture set up the flexibility of a total of two. One side of the Pei-ho at the ceremony in the spindle (Figure 2) * one installed in the hole in the tailstock end of the Nuo (Field 3) - its structure composed mainly of elastic sleeve 4 (7). Cone 2 (5) - Axis 8 (2) and clamping nut Round 7 (11), etc., for the tailstock end up centering fixture flexibility to increase the bearing's internal structure to enable them to carry out rotation. Work, the sub-set of fixtures installed on the lathe spindle taper and tailstock taper, the first cylinder loaded with a central spindle end up in,ed hardy uk, and then clamp the tailstock end of the push up fuel tank, leaving both ends of the processing cylinder curved part. Then tighten the two were tight four nuts in the central Chi 7 (11) t promote elastic sleeve 4 (7), 100-hole-centering position (the switch on page 42) * 42 * Mining Science and Technology 1998 4 installed without power compensation devices, the line loss only a year on saving 428 × l ~ kWh electricity.

At the same time supporting a set of tools designed to be fitted in the turret on the t. Such a clamping cylinder, will be able to complete the two wax turning, thereby reducing the labor intensity. Improve production efficiency. Meanwhile, the processing benchmarks and the design basis phase re-homes,true religion outlet, the concentricity requirement is guaranteed to improve the quality of the processing tank pumping, the set of tooling used in production,replica oakley sunglasses, turning the cylinder by a complex process simplification, and promoted production.
