Description

The invention relates to mechanical engineering, in particular, to cassette structures for positioning parts, and can be used for metalworking automation on the CNC-controlled walls served by robots, and in flexible manufacturing systems for oriented storage and transportation of products and workpieces.

The purpose of the invention is to expand the size range of the parts to be placed.

FIG. 1 shows cassettes for positioning parts, total zid; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a view of B in FIG. 2; in fig. 5 shows options for placing parts of various configurations in the cells of the cassette; in fig. .6 - node I in FIG. 3; in fig. 7 - mounting pin in the plate.

The cassette for positioning the parts comprises a rectangular shaped body 1, on the inner side walls 2 of which the guides 3 are placed. The guides 3 can be made, for example, in the form of screw-in strips 4. Thus, the guides of the 3 can provide folding or rolling over them, the installed p. pit 5 and 6 are installed on it. On the top plate 5 short pins 7 are mounted, on the bottom plate 6 - long pins 8, which exit one level with short pins 7 through through grooves 9, made in top plate 5. At the same time adjacent short 7 and long The 8 pins form a cell 10 for accommodating one or more parts II therein. Pins 7 and 8 are installed in threaded holes 12 made in plates 5 and 6. To do this, there are splines 13 on the end surfaces of pins 7 and 8, and threaded surfaces 14 at opposite ends. In case 1, a differential screw 15 is installed, having threaded sections 16 and 17 with different direction turns. The threaded sections 16 and 17 are mated respectively with nuts 18 and 19, which are rigidly mounted on the respective plates 5 and 6. At the same time, for unimpeded movement

The nuts 18 in the plate 6 are formed with a corresponding through slot 20. The rotation of the screw 15 is carried out beyond the spline surface 21, which can be shaped as. on at least one end of the screw 15, and in the central part. The choice of a constructive embodiment of the screw 15 in the part of the arrangement of the slit surface 21 depends on the choice of the drive. The drive can be a handle with a matching slit hole or a wrench for manual changeover of the cassette. For automated readjustment, translational and rotational movements of moving bodies of CNC or industrial robot equipment can be used, and the moving bodies themselves are equipped with corresponding rails, gear couplings or gears, providing kinematic engagement with the splined surface 21 and transmitting the screw 15 torque. Pins 7 and 8 can be threaded with plates 5 and 6. At the same time, the ends of the pins 5 and 6 have a threaded part that corresponds to the threaded holes of the plates. In the plates 5 and 6, additional threaded holes 22 are made, allowing reassembly of the plugs 7 and 8 and thus changing the dimensions and configuration of the cells 10 of the cassette. Replaceable basic elements can be installed on the pins x 7 and 8 at the level of contact with the part 11. Depending on the requirements for transportation conditions, the cleanliness of the mounting surfaces of parts 11 and the design features of the process equipment, the base element can be made in the form of an elastic sponge, a spring-loaded profile rail, etc. The profile stop can be made, for example, L-shaped, U-shaped in accordance with the configuration of the part 11 and the requirements of the conditions of its transportation. On the top plate 5, additional openings 22 can be mounted at the cells 10 technological devices, etc.

Preparation of the cassette for work is carried out as follows.

To adjust the dimensions of the cells 10 to the dimensions of the parts 11 placed in them, the actuator communicates the rotation to the screw 15 in the corresponding direction until the required dimensions are reached. At the same time, the upper plate 5 and the lower plate 6 simultaneously move along the guides 3 in opposite directions. The pins 7 and 8 fastened to the plates 5 and 6, forming the cells 10, approach or are removed relative to each other, ensuring the achievement of the required cell size 10. The unhindered movement of the plugs 8 relative to the plate 5 is provided with gaps in the through grooves 9. The required cell size

10 can be set directly on the part 11 when manually re-adjusting the cassette, or according to the control program of the corresponding actuator drive. Before installing or removing parts 11 from the cells 10 of the cassette, for example, the gripping head of an industrial robot, cells are needed. larger sizes than part sizes. In order to form gaps between the pins 7 and 8 and the parts 11, an additional rotation within one or two turns is communicated to screw 15. During transportation, it is necessary to fix the parts 11 in the cells 10 of the cassette. The gap between parts 11 and pins 7 5 and 8 can be selected by reverse rotation of the screw 15 by the appropriate number of revolutions. When changing the configuration and dimensions of the parts, the configuration of the cell 10 can be changed by appropriately reinstalling the pins 7 0 and 8 into the additional holes 22. During transport, the part 11 in the cell 10 is held by interchangeable base elements. The dimensions of the cells installed during the readjustment process are reliably fixed due to the fact that the rotation of the nuts 18 and 19 relative to the screw 15 is impossible. The screw-nut pair is a self-locking element. The spacing of the cells in the cassette and the coordinates of the geometric centers relative to the housing 1 do not change, i.e., 0 remains constant.

Along with strict cylindrical parts, cassette cells can store cylindrical parts that have cuts along them that form them, as well as prismatic parts. When storing the parts in a 35 cell, the cell-forming pins 7 and 8 can cover the part both outside and inside.

Changing the cassette to another part size can be done both manually and automatically. In case of automatic changeover of the cassette, rotation of the screw 15 at a given angle is provided either by a special programmable device, or by using translational or rotational 45 movements of the moving parts of the numerical control equipment or the industrial robot. For transmitting motion to screw 15 from the moving parts of the process equipment. Neither the robot located at the end of the shaft - 50 bar (the outer or inner splined surfaces) should automatically engage with the rail (gear, splined shaft surfaces) of the movable member. After that, the mobile unit of the process equipment or robot rotates or rotates by the value specified by the program in accordance with the required angle of rotation of the screw 15.

Making the cassette cells in the form of pins mounted on the sliding plates allows for quick resizing of the cells. Making additional threaded holes in the plates responding to the threaded ends of the pins allows the cell configuration to be altered by reassembling, adding or removing the pins when the configuration of the part changes, for example, a crank to a connecting rod. The installation of a screw in the cartridge case, kinematically connected with nuts fixed on plates and having the opposite direction of turns, preserves the coordinates of the cell centers, therefore there is no need for reprogramming 10

cash and cash during retransmission does not require additional space for storing unused tare, always in operation.
