The device includes a support frame 2, a mechanism for clamping and rotating parts (D) mounted on it, a transport rod (TS) 15 with pushing pawns 16. In front of frame 2 there are transport strips (P) 31, 32 of different heights. In the zone and behind the frame 2, transport P are located of the same height equal to the height of P 32. The frame 2 is mounted on rolling pins 3 with the possibility of vertical movement. For the TSH 15, there is a rotation drive in the form of a hydraulic cylinder 26 and a copier 21 is connected to it with a groove 22 for accommodating a roller 23 mounted on frame 2. A movable П 30 connected to the hydraulic cylinder is located at the level and on the P 31 side. is set to D 1 and moved by the dogs 16, resting on the P 30. In the area of the frame 2, the D 1 is clamped by turning TS 15 and retracting P 30. During the return stroke of TS 15, the copier 21, interacting with the groove 22, lifts the frame on the rolling pin 3 and D 1. The latter, due to the displacement of the center of mass, rotates and then stacks on floor level GP 2 yl.

Description

The invention relates to a machine tool industry, in particular to transport devices of automatic lines of machine tools, and is intended to rotate a part around a horizontal axis at one position of an automatic line.

The aim of the invention is to reduce the area.

Figure 1 shows a device for turning the workpiece on a conveyor, side view; figure 2 - section aa in figure 1.

The tilting device for workpieces 1 contains a support frame 2 that is vertically movable on stationary rolling pins 3. The frame 2 rests on springs 4, covering the rolling pins 3 and unloading the weight of frame 2 with part 1. The frame 2 has a clamping and turning mechanism parts 1 consisting of a hydraulic cylinder 5, the stem of which is connected to one of the arms of the two shoulders lever 6, having a pivot axis 7 mounted on the frame 2. The second double arm 6 is connected to the axis 8 installed in the frame 2 on which the bearing 9, a retainer 10 is mounted, fixing part 1 according to diameter D and pressing it against the presser disk 11. The latter is placed in bearings 12 on axis 13 mounted on frame 2. Placing a two-armed lever 6 perpendicular to axis 8 allows reducing force transfer losses clamping by hydraulic cylinder 5. In the initial position, axes 8 and 13 in the horizontal direction are shifted relative to the center of 14 tons of tin parts 1 by the value C.

The movement of the parts 1 is carried out by a sucker conveyor, on the rotary rod 15 of which is placed

rigid pushing pawls 16. The boom 15 is connected via brackets 17 to a carriage 18, to which is attached the cylinder body 19 of the axial movement, the rod of which is fixed on the fixed part 20 of the drive. Thus, the cylinder 19 provides longitudinal movement of the rod 15 and the carriage 18.

On the carriage 18 is mounted a copier 21 with a groove 22, which includes a roller 23 mounted in the sleeve 24 of the frame 2.

When the roller 23 interacts with the movable cam 21, the part 1 is lifted and rotated under the weight of the stop screw 25 fixed on frame 2. The screw 25 is displaced relative to the axes 8 and 13, in bearings 9 and 12 of which the part 1 rotates and is a reference point of the part 1 in the angular position relative to the axes 8 and 13. By adjusting the point of contact of the screw 25 and the end face M of the part 1, the position of the part 1 is achieved at which the axes 8 and 13 are rotated by the required angle, in this construction - 90.

The rotation of the rod 15 is carried out by a rotational drive in the form of a hydraulic cylinder 26, the rod of which is connected to the axis 27 mounted in the bracket 28 of the carriage 18. The axis 27 is connected to the rod 15 through a fork 29 by moving the axis 27 away from the hydraulic cylinder 26 and a rod 15 rigidly connected with it. At the end of the movable axis 27 there is a rigidly mounted transversely across the direction of movement of the rod 15. plank 30. The parts to be machined 1 to the frame 2 of the turner are mounted on uneven strips 31 and 32 and move along them Figure 1 on the right, direction move details from right to left), while

the strip 30 has a height of the strip 31 and is located on the side of the latter, and at the position of the frame 2 of the turner and after it (on the left in FIG. 1) both strips 33 have the same height equal to the height of the strip 32. This is due to the shape of the workpiece 1 and the technical process . (Figure 2 - the difference in height of the slats 31 and 32).

The device works as follows.

During the operation of the automatic line by the stroke of the rod 15 with dogs 16, the workpiece 1 is fed to the position of its rotation into the frame 2. From the hydraulic cylinder 5, through the lever 6 and the clamp 10, the workpiece 1 is fixed and then pressed the workpiece 1 to the presser disk 11, axis 13 the rotation of which is fixed to the frame 2. After fixing and starting processing on a machine (not shown), the rod 15 and the pawls 16 are rotated to the position from the part, and during the cylinder 26 turning to the left (Fig. 2), the rod 15 rotates to the right through the axis 27 and plug 29. Place to axis 27 to the travel bar 30 moves also to the left and out from under the workpiece.

Then, the carriage 18 is moved back from the cylinder 19 back (to the right in FIG. 1) and the transport rod is retracted 15. A copier 21 mounted on the moving carriage 18 of the conveyor drive moves relative to the rigidly mounted roller 23 placed in its groove 22. with frame 2, lifts the last for rolling 3 in the upper position I.

At the same time, part 1 opens from one of the transport strips 33, is rotated in bearings 9 and 12 of axes 8 and 13 under the action of its own weight, and rests against the limiter screw 25 of frame 2 with end M. At the same time, the center of gravity of the part moves to point K. details 1 to 90. Upon further movement of the copier 21, the frame 2 is lowered with part 1, the latter is placed on the transport strips 33 of the same height.

When a part is lifted into a tilter, it becomes necessary to maintain one side of the part, which is carried out by a feed bar 30, which

is entered at the position preceding the pivot position. In this position, the rod 15 with the dogs 16 is rotated to the position on the part and the input of the supplied bar 30 under the previous part through the axis 27 and fork 29. After that, the conveyor bar 15 with the dogs 16 moves the workpiece 1 supported by the rolling pin 3 to the next position automatic line.

The device returns to the position of capture of the part as follows.

After the part 1 is rotated by 90 ° and the carriage 18 is returned by the conveyor drive to the initial position, the detent 10 is removed from part 1 when

25, a fork 29 with simultaneous approach under the part 1 of the support bar 30 fixed on the axis 27 located in front of the tilter. After this, the rod 15 begins to move with the dogs 16 and the support plate 30 placed on the conveyor drive carriage 18 to the position of rotation of the part 1. At the same time, the copier 21 mounted on the carriage 18, moving relative to the roller 23 fixed on the frame 2, idly lifts the frame 2 to the position for gripping the part 1.
