Abstract

The invention relates to the field of machine-tool construction and metalworking, for example, handles for turning machines. The purpose of the invention is to increase the convenience of operation. In the device for activating and deactivating the handle of the feed mechanism, inside the handle 5, a spring 13 is mounted, attached to the stop 14 and connected through the cup 15 with the planet carrier 3. In the handle 5, a groove 16 is fitted to the conical recess 6. sleeve 10 rotatably around it. The device is convenient to operate, requires less effort to control the handle. 1 hp f-ly, 1 ill.

The invention relates to machine tools and metal processing, such as handles for turning machines.

The purpose of the invention is to improve ease of operation.

FIG. 1 shows a device, an axial section; in fig. 2 shows section A-A in FIG. one.

The device contains a gear wheel T, rigidly connected with the drive shaft 2 of the feed mechanism, drove 3, seated on bearings 4 of the drive shaft 2, handle 5 with a conical groove 6, ball 7, clamp 8 and spring 9 seconds. 5 the sleeve 10 is mounted for rotation on the handle 5. The sleeve 11 is prevented from axial movement on the handle 5; the cover 10 is secured to the sleeve 10 by screws 12; An extension spring 13 is coaxially placed inside the handle 5, one end of which is fixed to the handle 5 with the support 14, the other end rests against the glass 15 into the carrier. o 3. The conical groove 6 of the handle 5 is associated with the groove 16, the longitudinal axis of the handle 5 is longitudinal.

The device for activating and deactivating the handle of the feeder operates as follows.

In mechanical feed, when gear 1 is set in rotation with the drive shaft 2, the carrier 3 and the handle 5 do not take part in a circular rotation of 1 hp around the drive gear. 2. In manual feed, when the drive of the mechanical feed is turned off, the machine operator holds the handle 5 through the sleeves 10 in the hand and t not on yourself to failure. In this case, the ball 7 leaves the conical recess 6, falls into the groove 16 and displaces the retainer 8 towards the drive shaft 2. The end of the retainer 8 falls into the depression between gear teeth 1 and the rotation of the handle 5 is transmitted to the drive shaft 2. the conical recess 6 and is chosen in such a way that when the ball 7 is located in the groove 16, the end of the retainer 8 does not jam in the hollow between the gear eubes 1 and does not have a noticeable gap.

As soon as the machine operator releases the ru-55 loop to 5, the stretch spring 13 is 30

rotates the handle 5 to its original position, the ball 7 slides into the conical recess 6, the spring 9 pushes the retainer 8 towards the handle 5, the end of the retainer 8 emerges from the depression between gear teeth 1 and the carrier 3 with the handle 5 rotates freely around the drive shaft 2

The device provides more convenient use. The handle does not slip in the hand, since the sleeve is mounted on it so that it can rotate on the handle. The handle is easier to hold in your hand due to the fact that the compressive force of the spring 9 is perceived by the longitudinal groove in the handle and is not transmitted to the machine operator’s hand, and the force from the spring 13 is stretched inside the handle, which is perceived by the machine operator’s hand, changing the direction of the manual feed in the device is not a dead stop, because the latch 8 does not come out of engagement with gear 1.

Claims (1)

Invention Formula 1, A device for activating and deactivating the handle of the feed mechanism, consisting of a gear, rigidly connected with the drive shaft of the feed mechanism, drove with the handle, mounted with —the possibility of rotation on the drive shaft, a spring-loaded gear lock and ball — connected with the handle through a conical recess made in it, which differs in that, with the aim of increasing ease of operation, the handle is mounted with the possibility of axial movement relative to the carrier and the longitudinal axis of the handle, the groove is made - Gennes with a conical recess in the cavity of the handle coaxially arranged spring tension, one end of which is coupled to the abutment of the handle and the other end through the glass handle is fixed relative to the carrier. 2 ;, The device according to claim 1, about tl and - so that, in order to improve ease of operation, a sleeve is installed on the handle with the possibility of rotation on it. fig 2
