The invention relates to a machine tool industry, in particular to automatic lines for machining body parts, such as cylinder blocks.

The purpose of the invention is to expand technological capabilities by allowing the part to be reoriented to one of the machine tools of the line, a device for feeding parts from the conveyor, as well as using the grip of this device as the base element of the specified machine in the working area.

FIG. 1 shows the proposed automatic line, general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 is a view of B in FIG. I; in fig. 5 is a view of FIG. one; in fig. 6 is a section DD-D in FIG. four.

The automatic line is intended for final machining of the holes in the cylinder block assembled with the caps of the main bearings, screwed with horizontal and vertical bolts.

An automatic line consists of technological equipment installed along the process and interconnected by a single conveyor belt.

At the beginning of the line, metal-cutting equipment was installed from five machine tools I-V intended for roughing and semi-finishing boring of holes in the cylinder block for the camshaft bushings and, under the crankshaft bearings.

Next, a three-sided aggregate thread-screwing machine VI is installed, which, in order to relieve stresses in the parts after roughing and to increase the precision of the finishing, unscrews and then tightens the vertical and horizontal bolts securing the bearing caps to the block.

At the end of the line there are three machines VII-IX intended for the finishing boring of these holes in the cylinder block assembled with the main bearing caps.

The workpiece 1 in the line is transported by a single conveyor-conveyor for the whole line with a part lifting 275 mm to transfer the latter over the bearing supports of 2 fixtures of boring machines I-V, VII-IX and install them (parts) in the fixtures.

The lifting of the transport belts 3 is carried out from the hydraulic cylinder 4 through the lever system 5, and they are progressively moved from the hydraulic cylinder 6.

The three-sided threading machine VI consists of a bed 7 on which movable horizontal tables 8 and 9 with multi-spindle and boxes 10 and 11 are mounted, the spindles of which are provided with nut drivers 12 for unscrewing and screwing in horizontal bolts 13. Beside that.

The stand 7 has a stand 14 with a vertical table 15 with a multi-spindle box 16, the spindles of which are equipped with wrenches 12 for unscrewing and screwing up the vertical tightening bolts 17 in the workpiece 1, and also the device 18 for feeding parts 1 into the working area of the machine VI located perpendicularly the main movement of the part in the line, equipped with a U-shaped gripper 19 for fixing and clamping the workpiece and the mechanisms of the actuators 20 and 21 of the reciprocating movement and rotation around the horizontal axis 22. Thanks With the actuator 20, the gripper 19 can move perpendicular to the direction of the main movement of the part in the line. When lowering the conveyor belts 3 of the conveyor-conveyor at the position of the unscrewing machine, the VI part 1 is installed on the base bars 23 and the locking pins 24 of the grip 19. At the same time, in the processing area of the machine part 1 remains at the top of the grip 19, It is poured into special platforms (not shown), and at the working positions of boring machines IV, Vli-IX, part 1 is lowered onto the basic elements of the fixture (not shown), where it is fixed and clamped.

In the gripper 19 of the machine VI, the part 1 is mounted on the locking pins 24 by the clamp 25.

After the belts 3 of the transfer container 3 are lowered to the lower position, the gripper 19 from the rotation actuator 21 rotates 180 ° around the horizontal axis 22.

Three-sided thread-screwing machine built into the automatic line works as follows.

After roughing and semi-finishing machining of the holes on the machines IV, part 1 is fed by a conveyor into the grip 19 of a three-sided threading machine VI and clamped 25. Then the grip 19 with part 1 is rotated 180 ° around the horizontal axis 22 from the rotation actuator 21, the device 18 moves the gripper 19 with part 1 to the machining position of the VI. Next, the movable table m. 8, 9, 15 with spindle boxes 10, 11, 16 communicates the working feed, the wrenches 12 are unscrewed and the subsequent tightening of the fastening bolts 17 and the bolts 13 of the main bearing caps which are assembled with part 1 At the end of this operation, all the spindle boxes 10, 11, and 16 return to their original position, and the gripper 19 with the machined part 1 returns to the position of the conveyor belt next to the axis 22 by means of the reciprocating drive 20.

180 ° in the opposite direction. Then the transfer conveyor picks up the finished part 1 and transfers it to the next positions of the automatic line for finishing on the VII-IX machines.

The next part 1 is loaded into the fixture 19 and clamped. The cycle is repeated.
