Abstract

The invention relates to a machine tool industry, in particular to accessories for drilling machines. The aim of the invention is the expansion of technological capabilities by providing the possibility of processing in a single conductor cylindrical detershel of several sizes with minimal cost for its readjustment. For this purpose, the conductor plate 6 is installed pivotally, on the driven rolling pin, the number of holes in it under the guide rolling pin 5 corresponds to the number of workpieces, and they are made at the intersection points of the circle, which is concentric to the axis of the driven rolling pin with a plane perpendicular to the prism axis 10 and passing through the axle of the rolling pin. In this case, the conductor sleeves 13 are installed in the holes made in the conductor pin 6 on the tangents to the circle, with a radius equal to the distance from the axis of the conductor plate to the axis of the prism 10, with an offset from the relative point of contact. 1 hp f-ly, /. silt to (L with 4 00 about fie1

Description

The invention relates to a machine tool industry, in particular to adaptive. not for drilling machines,

The aim of the invention is the expansion of technological capabilities by providing the possibility of processing in a single jig cylindrical parts of several sizes with minimal cost for its readjustment.

Figure 1 shows the proposed conductor, longitudinal section; on fig2 - view A on ymg ,,

The rocker jig includes a housing 1, in the vertical holes of which a driving pin 2 is placed, connected to a workpiece clamping drive (not shown), turned on by a handle 3 and a spring rolling pin 5 spring-loaded 4, Rotating conductor plate 6 is fixed on the driving rolling pin 2 by a nut 7 On the top plate 8 of the housing 1 by means of the adjusting fingers 9, a prism 10 is fixed for mounting the workpieces 11, the axial position of which is limited by the stop 12, in the conductor plate 6 there are conductor sleeves 13 with shoulders 14, O The conductor sleeves 13 are located on the tangents B to the circle B, having a radius equal to the distance from the axis of the conductor plate 6 to the axis of the prism 10, and are offset from the contact point by a distance determined from the ratios:

where L is the magnitude of the displacement of the axis of the conductor sleeve 13 relative to the point of contact;

C is the distance from the base stop to the plane that passes through the axis of the driven rolling pin and is perpendicular to the center of the prism; 1 is the distance from the base stop to the axis of the conductor sleeve. The value C is determined on the basis of the requirement that the minimum outer diameter of the conductor plate 6 be maintained:

details.

In the conductor plate 6 on a concentric circle g, the radius of which is equal to the distance from the axis of the driving rolling pin 2 to the axis of the guide

rolling pins 5 holes 15

under the guide rolling pin 5, the number of which corresponds to the number of parts machined in the conductor, and for each machined

The hole 15 is made at the point of intersection of the circle Г with the perpendicular that was reconstructed from the corresponding tangent point of the contact point B. Each hole 15 is marked by the designation of the workpiece 11 that corresponds to it.

The conductor works as follows.

The nut 7 is unscrewed, the guide pin 5 is pulled out of the hole 15 of the conductor plate 6, and the latter is turned along the drive pin 2 until it coincides with the axis of the guide pin 5 of that hole 15, the marking of which corresponds to the designation of the workpiece, after which the hole is inserted into this hole Rolling pin 5 o Then tighten the nut 7. The workpiece 11 is installed in the prism 10 and is sent to the stop 12, Then the handle 3 starts the part clamping drive and the conductor plate 6 by means of the collar 14 of the conductor sleeves 13 t workpiece 11 „
