Abstract

The invention relates to machine tools, in particular, to devices used in modular machine tools for mounting detail cassettes. The purpose of the invention is to automate the installation process. Cassettes 3 with parts 4 are installed on the case, as well as cassette clamping mechanisms: transverse 5, longitudinal 6, and vertical fasteners on top 7. Parts cassettes are mounted on the base lug on housing 37 and clamped alternately by triggering mechanisms. After turning, the cassette 3 is pressed again to the same mounting base, thus providing increased accuracy. 18 il.

FIG. 9 shows section EE of FIG. four; in fig. i О - section Ж - Ж in FIG. four; in fig. 11 is a sectional view 3-3 of FIG. four; in fig. 12 - AND. figure 4; on Fig - cassette, General view; in fig. 14 - the same, top view; on .fig. 15 is a cross-section K-K in FIG. 13; in fig. 16 is a section L-L in FIG. 3; in fig. 17 is a section through the fl-M in FIG. 14; in fig. 18 is a section HH on Fig,

The clamping device consists of a housing 1 centered by two dowels 2, a cassette 3 with flat parts 4 located therein, for example, linotype matrices, and mechanisms for the sim: transverse 5, longitudinal 6 and vertical clamping from above 7.

The transverse clamping mechanism 5 consists of an injection-free pneumatic cylinder 8 built into the housing with two

pistons 9 with fastened on them; pin clamps 10 installed in pgs of the cylinder body, moreover, the pistons are separated by a spring 1.

The mechanism 6 of the longitudinal zansima consists of a pneumatic cylinder 12 built into the body 1, the stem of which 13, placed in the guide sleeves 14, has a wedge 15 at the end, which is interoperable with the eccentric 16, the second end of which with a clamp 17 acts on the end of the stack of blanks 3, carried out a longitudinal clamp to the adjustable stop 18, the Eccentric 16 is mounted on a horizontal axis.19, on the ends of which the torsion return springs 20 are mounted.

The clamping mechanism on the top consists of a device that is built into the housing, and is a cylinder 21, the stem 22 of which is rag: still in the directions 23, has a wedge 24 in the middle part that is interoperable

VIA with a roller 25 mounted on a horizontal axis 26 to t 27, placed vertically in the guide sleeve 28 with the possibility of vertical movement. The upper end of the rod 27 on the horizontal axis 29 is equipped with a rocker 30, on both ends of which two more rocker arms 31 are mounted, the ends of which fit into the grooves of four clamps 32 interacting with springs 33 located in the sleeves 34, with the possibility of vertical movement and interacting with cassette 3 at four points.

A cassette having an understitch 35 for passing the tool 36, with the parts 4, is mounted in the fixture on the base plate 37, fixed on both sides by roller rollers 39 mounted on the axes 38, the input is 1CIM in the grooves 40 and the springs 41 pressed to the cassette. removed from the tool, and to prevent parts from falling out provided with tongs 42 with a spring 43.

The clamping device works in the following way.

When a clamp command is received, the pneumatic cylinders of the clamping mechanisms alternate; cross, longitudinal, clamp. The piston 9., moving to the right, compressing the spring 1i with the left gripper 10, presses the cartridge 3 which presses the parts 4 against the clamping bar 37.

- The rod 13, moving to the right, the wedge 15 turns the eccentric 16, twisting the spring 20, presses 17 on the pack of parts 4, pressing them against the adjustable stop 1 8.

The rod 22., moving to the right, the wedge 24 moves down the roller 25 and from 27, which, through the rocker arms 30 and 31, squeezing the spring 33, lowers the hooks 32, pressing the cassette 3 and part 4 to the clamping bar 37 ..

Details are clamped on three sides and centered on the clamping bar. . Mechanical machining of parts is performed from above.

After the command to release the rods 13 and 22 under the influence of the springs 20 and 33 are moved to the left, respectively, the claws 32 are lifted, and the eccentric 16 with its grip releases the parts.

The left piston 9, which is pressed by the spring 11, returns to its original position, retraction of the left-hand grip 10 of the cartridge.

The cassette can be removed, rotated 180 around the longitudinal axis and re-inserted into the device.

After turning, the longitudinal and vertical clamping mechanisms work similarly to that described, and in the pneumatic clamp of the transverse clamp 5 the right piston 9 now moves, the right clamp 10 acts on the cassette 3, retaining the same basic

Invention Formula A clamping device for prismatic blanks mounted in a cassette, containing a housing with transverse, longitudinal, and vertical clamping mechanisms located on it, in order to automate the installation of the cassette, the device is provided with a basing plate located on the housing, shaped and installed with the possibility of rotation around the longitudinal axis. 2 View 5 Thebes 5 Phie.
