Description

Charging devices are known for machine tools that process, for example, crankshafts made in the form of a carriage with grippers moving along a crank.

The disadvantages of these devices are large. 11 and shock loads that occur when the high speeds are at the end of the turn, and c;) the switching mechanism from the longitudinal stroke of the carriage to the movement of the grippers,

The proposed device is characterized in that it is provided with a retarding mechanism, made in the form of a gear. installed on the carriage, interacting with the rack through the air line and informing the carriage of the accelerated (slow) movement related to the rail moving at a constant speed, at the moments when the roller passes; on the arm of the lever, rigidly connected with the toothed sector, the curvilinear sections of the groove are made along the guide.

crawling through a scaffold mounted on it.

The gripper control is performed by means of iesterni. installed on the axis of the grippers, and a spring-loaded rail, locked in the loading position by a lever and a spring-loaded latch when the lever interacts with the stop and released in the loading position when the stop is pressed against the other lever that opens the latch.

Fig, 1 shows the proposed device; in fig. 2 - carriage.

The loading device consists of a gearbox 1, on its shaft, a drum 2 is installed with a cable 3 wound on it, tensioned on blocks 4. The cable is attached to a rail 5 installed in the guides of the carriage 6, which moves along the beam 7. A groove is made on the beam 8, consisting of a rectilinear section, parallel to the caption of the carriage movement, and

curvilinear sections in the positions of loading and unloading; In the groove there is a roller 9 fixed on one shoulder of the lever 10 mounted on an axis in the carriage body. The other lever arm, made in the form of a toothed sector 11, is in engagement with gear 12, which is on the same axis with gear 13, which is engaged with the lath. A crank 14 is fixed on the same axis, through the connecting rod 15, which moves the slider 16 along the carriage guides. In the lower part of the crawl on the axis 17, clamps 18 are made for goods that turn when the gear 19 interacts with the rack 20. The latter is stirred up by the action of the spring 21 when it hits the loading position against the stop 22 of the lever 23, which turns the latch 24 to release the lever 25. the slats are down at the unloading position when the lever 25 interacts with the stop 26. The device operates as follows. To move the carriage 6 from the unloading position to the loading position, the drive is turned on. In this case, the drum 2 rotates, which through the cable of 3 tons does not have the rail 5 (in the drawing to the right). The rail rotates the gear 13, and sitting on the same axis as the last gear 12 rotates the sector 11 of the lever 10. The lever rotates the roller 9 along the curvilinear portion of the groove 8. At the same time, the carriage remains stationary. At this moment, the crank 14, through the crank 15, lifts the slider 16 upwards. When roller 9 moves from the curved section of the groove 8 to the rectilinear angular velocity of the gears 12 and 13, the carriage 6 is reduced relative to the rail. beam 7. In the straight section of the groove 8, the rotation of the lever 1O is stopped, therefore the rail 5 does not move relative to the carriage 6, and the speed of the latter reaches a maximum value equal to the speed of the rail. When approaching the loading position, the roller 9 of the lever 1O enters another curved section of the groove 8. Similarly to the above described, the speed of movement of the carriage on the beam gradually changes from a maximum to 1 tup. Simultaneously, the crank mechanism 14-15 lowers the slider 16 down. When it is lowered, the lever 23 slides against the stop 22, which pushes away the spring-loaded latch 24, which releases the lever 25. Under the action of npy; KiiKi: i 21 rail 20 rises up and locks grippers 18 through gear 19. The part is taken up. The drive automatically shuts down. When the drive is reversed, the slider 16 rises up, the carriage, gradually gaining speed, begins to move toward the unloading position, where the cycle repeats with the only difference that the opening of the grippers 18 occurs when the lever 25 is thrust on the support 26. The lever 25 will act on the rail 20 , displaces it by clamping the spring 21. In the extreme position, the spring-loaded latch 24 locks the lever 25. Claim 1.
