Abstract

The invention relates to the processing of materials by cutting, in particular, to devices for mounting parts on CNC machines, and allows for improved reliability of fixing parts. Packages of parts 16, installed in the seats 13, are pressed against the base surfaces of the 15 mounting elements. The package of parts 16 is clamped by cams 10 and 11, which are acted upon by rocking 9 wedges 7 of a slider hinged on the actuator pusher 3. The slider is made in the form of a strap 4, at each end of which an additional strap 5 is installed with the possibility of movement in the restrictors 6 fixed in the housing 1. In turn, at each end of the strap 5 a wedge 7 is freely installed, oriented by the opening of the housing 1. Slats 4 and wedges 7 are equipped with spherical tips 20 and 21, and additional bar 5 with radial tips designed to interact with the walls of the groove of the housing 1. When moving the pusher 3 upward, the package of parts 16 is clamped, and during the reverse movement - once bench press 3 il.

Description

The additional strap 5 is movable in the restraints 6 fixed in the housing 1. In turn, a wedge 7 is mounted at each end of the strap 5, oriented with the opening of the housing 1. The slats 4 and the wedge 7 are equipped with spherical tips 20 and 21, and additional bar 5 — radius tips designed to interact with the walls of the groove of the housing 1. When moving the pusher 3 upwards. clamping packages of parts 16, and during the reverse movement - unclamp. 3 il.

The invention relates to the processing of metals by cutting, in particular, to devices for mounting parts on CNC machines.

The purpose of the invention is to increase the reliability of fixing parts.

Figure 1 shows the device, a longitudinal section; in figure 2 is a section aa in figure 1; on fig.Z - device top view (rotated).

The device comprises a housing 1 in which a drive with a rod and a pusher 3 is installed, on which a slider is hingedly mounted, made in the form of a strip 4, on each end of which an additional rail 5 is installed with the possibility of movement in the limiters 6 installed in the housing 1. In In turn, at each end of the bar 5, a wedge 7 is freely mounted, oriented by the opening of the housing 1, spring-loaded from above and fitted with a stop 8 for the downward movement

On the body 1, the rocking chair 9 is freely mounted, each of which interacts with its middle part with the “corresponding bevel of the wedge 7, and the ends with the cams 10 and I fixed to the body 1 with the possibility of

reciprocating movement.

To limit rotation of the strip 4, pre-mount the bracket 12 mounted on the housing 1.

Seat 13 is made on housing 1 with mounting surfaces 14 and 15 for mounting parts 16 and a groove 17 with a mounting element 18 housed therein, fixed with the possibility of vertical movement from lever 19, hinged: fixed on pusher 3. Plank 4 and wedge 7 provided with spherical tips 20 and 21, and the additional rail 5 with radius tips 22, designed for

interaction with the walls 23 of the groove 24 of the housing 1,

The device works as follows.

The device is mounted on a vertical milling machine. A CNC (not shown) is oriented along a slot in the machine table onto the clamping keys (not shown) and secured. Install the parts 16 to be processed, in the seats 13 and sent to the installation element 18.

When the drive is turned on, the rod 2 moves the pusher 3 with the slide 4 up. At the same time, the wedge 7 presses the rocking chair 9, which in turn presses the cams 10 and 11, which press the parts 16 to the base surfaces 15.

Simultaneously with the movement of the pusher 3 upwards (clamping), the adjusting element 18 under the action of the lever 19 moves downward, making room for a cutting tool (not shown),

The unclamping of the parts 16 is carried out in reverse order. When the stem 2 is moved down, the slant 4 is lowered, the wedge 7 at the same time releases the rocking 9. The cams 10 and 11 return to their original position under the action of springs, freeing the details 16. At the same time, the adjusting element 18 rises up to its original position
