Abstract
A multispindle thread cutter apparatus is proposed, which has a drive shaft (3) to be driven by motor and which has a plurality of work spindles (4). Interposed between the drive shaft (4) and the work spindles (4) is a distributor and reversing gear (33), by way of which the work spindles (4) are driven to rotate by the drive shaft (3). Each work spindle (4) is assigned its own single reversing coupling (34), which has its own single switchover device (35), so that the directions of rotation of the work spindles (4) can be reversed while the drive shaft (3) continues to rotate uninterruptedly in the same direction.
Claims17
A multispindle thread cutter apparatus, comprising:
- a drive shaft including means to be driven by motor;
- a plurality of work spindles disposed side by side, each one of the work spindles including means for the one of the work spindles to be equipped with a thread cutting tool;
- and
- a distributor and reversing gear interposed between the drive shaft and the work spindles, including
- two gear wheels, driven to rotate in opposite directions by the drive shaft,
- means for the work spindles to be driven to rotate by the drive shaft, and
- an indexable reversing coupling device, the reversing coupling device including means for the directions of rotation of the work spindles to be reversed while the drive shaft continues to rotate uninterruptedly in a same direction,
- the two gear wheels, driven to rotate in opposite directions by the drive shaft, being coupled in alternation to the work spindles;
- wherein
- the reversing coupling device comprises a plurality of single reversing couplings (34), each of which includes a respective single switchover device (35), and
- each of the plurality of work spindles (4) includes a respective single reversing coupling (34) of the plurality of single reversing couplings (34).
