The floating position of the holding fixture in a rotary transfer device is used to

Explanation:

Rotary transfer device

• The rotary transfer device moves the workpieces in a circular path, which usually has a maximum diameter of about 3 m.
• Most of the rotary transfer devices are dial indexing machines, but some other rotary mechanism, generally more rudimentary, can also be considered for rotary transfer.
• The dial indexing machine is an ideal choice for a transfer device when the total number of production operations required is rather low and not too complicated.

Rotary table:

• This is the least expensive of the rotary device.
• The rotary table is driven by a pneumatic or hydraulic cylinder, which actuates a rack and gear mechanism to convert linear motion to rotary motion.
• As the gear rotates, the Ratchet-Pawl is driven into teeth of the Ratchet gear attached to the dial table, causing the dial to index.
• The rotary table gives an accuracy of 0.125 mm, the index table gives better accuracy depending on the specific type of drive, reaching in some cases an accuracy close to ± 0.25 mm.

​

Floating position:

• To improve the accuracy in both these types of tables, a floating position of the holding fixtures could be used.
• In order to obtain the floating position, the holding fixture is built with a floating side in which holes for securing pins are drills.
• A set of securing pins is attached to the tools in such a way that they reach the holding fixture before the tool. When the pins reach the fixture, they will enter the holes drilled for them, these securing the holding fixture.
