Abstract

The invention relates to the field of machine tools and can be used in machine tools for moving parts. The aim of the invention is to increase the reliability of the device by providing a smooth rise and lowering of the transfer rod. From the cylinder 15, the levers 3 move and along with them the axles 5 move in the longitudinal groove 6 of the transport rod 2. The spring presses the transport rod to the stop 11 and simultaneously moves the plunger to the right. Due to this, the transport rod 2 with part 14 rises smoothly. Movement only vvvrh occurs until the plunger selects the entire stroke and the axis 5 of the levers 3 is not pressed into the opposite plunger. Then, the transport rod 2 with part 14 is moved to the right along a circular path. At the end of the stroke of the cylinder 15, when the transport rod 2 abuts against the stop 12, the axis 5 begins to compress the plunger and, moving in the groove 6, lowers the transport rod 2 with the part to the base. 3 il.

Description

I

The invention relates to a machine tool industry and can be used in machine tools for clamping a part.

The aim of the invention is to increase the reliability of the device by providing a floating lift and lowering of the transport rod.

until the plunger 8 selects its entire stroke and the axis 5 rests against the opposite side of the submersible piston 9. The springs 7 are chosen in such a way that when the part 14 is twisted, the axis 5 remains in the middle of the groove. Then, the part 14 is moved to the right along a circular path, At the end of the stroke of the cylinder 15, at the moment when the melody part 14

lifting and moving parts j on fig 2 and base strips 13 remains the incision A-A in fig 1; Fig, 3 is a section bB in Fig about 1,

The proposed device contains a base 1, the transport rod 2, the levers 3, the axis 4 which one ends. The hinges are fixed on the base 1, and the second axes 5 are placed in the longitudinal grooves 6, made on the ends of the transport bar 2, In the grooves b between the axles 5 there are sub-brakes 7 with respect to the transport bar and opposite to each other of the piston 8 and 9; The spun plungers 8 and 9 are perpendicular to the axis 5, with the ability to interact with them and / have a movement restriction, and on the ends of the base 1 in the brackets 10 there are mounted stops 11 and 12, alternately interacting with the transport rod 2 in the extreme half.

On base 1, there are base straps 13J on which the lips5:; a. In. Are placed. details 14, and fixed hydrocylnds 15, SB 16 and T 16 through axles 17 with levers 3,

A device for lifting and moving parts works as follows.

From cylinder 15, through axis 17, movement to the right is transmitted to levers 3. Together with levers 3, axes 5B are interleaved to longitudinal groove 6 of transport rod 2. Spring 7 (left) transport rod 2 to stop 11 and at the same time the sub-valve 8 moves to the right . Due to this, the transport rod 2, and together with it the part 14, is lifted "Movement only upwards takes place until then."

until the plunger 8 selects its entire stroke and the axis 5 rests against the opposite side of the submersible plunger 9. The springs 7 are chosen in such a way that when the part 14 is split, the axis 5 remains in the middle of the groove. Then, the part 14 is moved to the right along a circular path, At the end of the stroke of the cylinder 15, at the moment when the melody part 14

and the base bars 13 remain not

a large gap, the transport rod 2 rests on the support 12. The movement of the transport rod 2 and the part 14 to the right is stopped. The axis 5 begins to compress through the spring-loaded plunger 9 the spring 7 (right) and, moving in the groove 6 ,. lowers the transport rod 2 and the part 14, the part of the movement E1; is placed on the base bars 13 without horizontal movement, and the ride bar 2 falls below the base bars 13,

During the return stroke of the cylinder. 15, the sequence of movements and operation of the device are similar to those described above.

Formula 1 1

0

A device for lifting and moving parts, comprising a base, a transport rod, levers, the axes of which are pivotally mounted at one end on the base, as well. others on the transport rod, and a lever rotation drive, characterized in that, in order to increase the reliability of the device, it is equipped with two control-i, oppositely located relative to each other on the base with the possibility of interaction with the end surfaces of the transport rod and QM pairs of plungers spring-loaded relative to the transport bar that are opposed to each other and located in additionally made; at the ends of the transport rod, there are horizontal longitudinal grooves, and the upper eyes of the levers are mounted so that they can move along the above-inserted slots and interact with the spring-loaded plunger.
