Hydracopy sulports are known for threading lathes with ram cylinders connected via a follower slide and a stylus with a copying device for radial locking and retraction of the tool.

The purpose of the invention is to simplify the construction, as well as to ensure the cutting of the tapered thread.

For this, the copier device is made in the form of two flat cam mechanisms, the pushers of which represent one ilpex arm, the two arms of which interact with two cams, and on the third, the ruler in contact with the probe is attached to the angular position.

FIG. 1 shows the kinematic diagram of the machine; in fig. 2 - the position of the caliper, corresponding to the output of the cutter from kA «av. Thread; in fig. 3 - soup port in the working position (and threading).

The copier in the form of the three-arm cocTOHiT lever of the levers 2 and 5 mounted on the common ruler of copier 1, the levers 2 and 5. The ruler-copier is rigidly connected to the axis, rotates with it at a certain angle and is in constant contact with the probe of the next spool 4. Lever 2 with its probe 5 it contacts with the cam cam of m 6 depth feed, and the lever

3, with its roller 7, rolls around the rotating cam 8 of the pick out from the groove.

A kinematic machine chain, for example, a thread-turning machine, on which the proposed caliper can be used, contains a helical chain, a spindle 9 and a slit shaft 10, gears 11 and 12, a shaft 13, a copier drum 14 and a longitudinal slider 16 connected with it through the roller holder 15.

The depth cutter feed chain consists of bevel gears 17 and 18, the transfer of a periodic action - drove 19 and the pinwheel 20, gears 21 and 22 of the guitar tuned to the number of passes, gears 23 and 24, cam

6 feeds to the cam depth 25 of the end of the cycle and the cam 26.

The cutter output chain has gears 27 and 28 s. gear ratio of 1: 1 and cam 8 output of the cutter from the thread of the thread.

The movement from the slit shaft 10 through the cylindrical gear 11, 12 and the cam clutch 29 is connected to the drive drum 14 and the shaft 13. To form a thread, the groove of the drum 14 during rotation provides a reciprocating motion along the axis

spindle longitudinal slide 16 caliper.
