Description

The invention relates to a machine tool industry, in particular to a retrofitted tooling used to install a workpiece on machine tools.

The aim of the invention is to improve the accuracy of the installation of the workpiece, increase, rigidity and reduce the size of the device.

FIG. 1 shows a universal collapsible device (USRP) type square, section; figure 2 is a view of And figure 1; Fig. 3 is a sectional view of Fig. 1 (USRP tuning unit); figure 4-case of a dihedral prism, end view; figure 5 - tetrahedral prism, top view; Fig. 6 shows the layout of the USRP-OZ square with a special collet chuck when alignment is required on the base surface; in fig. 7 — layout of the sinus device; on Fig - layout with a vertical stand; Figure 9 shows a sinus adaptation of the USRP for a 0 °; figure 10 is the same for a 90 °; in fig. 11 - USRP in the layout with a standard plate USP; in Fig.12 is a view of E in Fig.11.

USRP contains the base plate 1, case 2, in which grooves are made, one of which forms a niche 3. The base plate 1 is installed in a niche 3 on the axis x 4, which are screwed into the base plate 1 and passed through holes 5 opposite side ribs b forming a niche 3. Grooves with coaxial threaded holes 7 are made on the two side faces of the slab 7. Fingers 8 are screwed into hole 7.

Perpendicular to its axis, a threaded through hole 9 is made on the cylindrical surface of the finger 8, designed to install the adjusting screw 10. The latter is also installed in the longitudinal groove 11 of the housing 2 and is deprived of axial movement by means of a plate 12 fixed to the case.

The fingers 8 are placed in oval grooves 13, made in the ribs 6, and are located either along the arc relative to the centers of the holes 7 or in the horizontal direction to ensure the adjustment of the plate in the given parameters. On the threaded part 14 of the fingers 8 protruding beyond the fins 6. a washer 15 m of a nut 16 is installed. For additional fastening of the plate 1, the fingers 17 and 18 installed in the housing 2 are designed.

8 base plate 1 is made of a coordinate grid of B or T-shaped grooves, or U-shaped, identical to the grooves used in the standard USP system

(GOST 31.111.40-83), at the intersection of which clean holes 19 can be made, and differently sized threaded holes 20 and 21 coaxially with them for the purpose of fixing the fixing standard scale.

If necessary, a threaded rod 22 can be screwed into the hole 21, which passes through a hole 23 made in the wall of the housing 2. The hole

23, a chamfer 24 is made on a smaller diameter, on which a spherical washer 25 is mounted with a nut 26 screwed onto a pin 22. In addition, in the base plate 1 there are threaded holes in which

screws 27 are screwed in, which act as stops and create resistance to the stresses generated by the nut 26 and the cutting forces during processing.

In addition, in order to reduce weight

USRP and compact design of the base plate 1 is made lightweight by about 1/3 in contrast to standard plates of identical dimensions, for which instead of a solid volume on the base of the plate 1

The bosses 28 are made, through the axes of which the threaded holes 20 and 21 pass. The bosses 28 have the shape of a truncated cone - this is dictated by the operating conditions of the base plate 1. Therefore, the holes 23, made on the side of the niche 3, also have a taper. Moreover, with the minimum approaching, the bosses 28 are buried in the hole 23 or partially come out as the angle a is mined, i.e. less than 90.

Figure 4 shows the design of the USRP of a dihedral prism, where in the case of the support 29 there are niches identical to the niches 3 of case 2 (figs 1-3), in which two plates 1 are installed with all listed

above mounting attachments.

Figure 5 shows the structure of a four-sided prism USRP: in the case 30, niches are made identical to those of case 3, in which four plates 1 with

all the above attributes (Fig. 1-3).

An example of the use of USRP in conjunction with a special device 31 is shown in Fig.6.

Fig. 7 shows an example of the arrangement of a sinus device using the plate 1, the fingers 17 and 18 together with the standard USP elements. If necessary, adjust the angle of 26 ° 17 10

increased accuracy can be used standardized pads 32 with a specific value. Sinus device can be installed either on the table of the Machine, or on the plate 33 USRP, installed on the table of the machine type machining center (USPP-OC).

Sinus device on the base of the plate 1 USRP (Fig.8) can be performed in the case when the angle a is closer to 90 ° using standard elements USP and USPP-OC.

On the base plate USPP-OTs (FIG. 9), a casing is set - angle 2 (USPR), the axes 4 are screwed into the extreme holes 7 of the plate 1 through additional holes 5 made in the ribs 6, and the holes 1 of the plate 1 located on the opposite side , - axis 4 through the smooth holes of the standard angle 34 (USP), which is installed on the measuring spacers 32 (possibly USP) and on the plate 35 with a T-shaped groove. Such a change is applicable to angles much larger than 93.

Figure 10 shows an embodiment where a rigid adaptation of the USRP with angles a from 1 to 87 ° is required.

Adaptation USRP (Fig.11) is made on the basis of the housing 2, (29, 30) in the layout with standard plates 35 (USP), for which additionally holes for fasteners are made in the cases. In the ribs 6, the oval grooves 13, 36 (FIG. 4) are made through in order to attach the fastening standard bolts 37 installed in the T-shaped side slots of the plate 35 to which two standard elbows 38 are screwed, in which smooth axles 4 axles are inserted After alignment, nuts 16 are tightened.

The screws 27 are screwed into the threaded holes of the plate 35 (Fig. 12), and the studs 22, passed through the additional holes 39 made in the wall of the housing 2, are in a twisted order.

Depending on the conditions and technology of processing parts 40, the work of the USRP may be different.

If the workpiece 40 is directly installed on the surface D of the base plate 1, then the position of the surface F is pre-adjusted (Fig. 6). Then, after securing the housing 2 to the machine table 41 and loosening all fasteners 4, 16,18,26 and 27, adjust the required position of plate 1 with screws 10, then fix the plate.

If a long-term adjustment of this position is required, then it is possible to use quick-hardening mixtures according to known technology.

In the case when a special tool 31 is installed on the surface D of the plate 1, in which the workpiece 40 is placed and secured, it is necessary to calibrate the required position on the special device based surface 31 (Fig. 6). From the elements of USRP possible layout of sinus devices (Fig.7 and 8) using standard elements from the system of the USP and the unified USPP-OC (see Fig.9-12).
