DEVICE FOR HANDLING.

The utility model relates to the field of equipment for machine tools and can be used, for example, for drilling holes for pins to connect parts or assembly units to a single unit.

Known rotary device for machining holes on vertical drilling machines, comprising a base on which a faceplate (housing) with elements for mounting and securing the part is mounted rotatably. At one of the ends of the body at predetermined angles, several holes are made with which the latch interacts. The case is equipped with a bush for a cutting tool.

(see P. P. Kosov "Machine tools for parts of complex shape, Moscow," Engineering, 1973, pp. 190 - 191, Fig. 141) is the closest analogue.

As a result of the analysis of the design of the known device, it should be noted that it is inconvenient when drilling holes in parts of complex shape or assembly units. When processing parts or assembly units of this category, one of the most complex and time-consuming operations is the precise installation of parts in a conductor (fixture). In the known device, the installation of this category of parts is very inconvenient, and can lead to inaccurate installation of parts (assemblies) and, as a result, to inaccuracy in their processing.

The objective of this utility model is to develop a device that allows you to quickly and accurately set parts (y3.nii) in a predetermined position for machining and thereby ensure that holes are drilled in a precisely specified location.

THE POSSIBILITY of turning the case with elements for installing parts or assemblies and fixing elements in the case, and on one of the ends of the case there are holes for fixing the case in a predetermined position by a latch mounted on the base and having the ability to enter one of the openings, is new, that the device is equipped with supports pairwise mounted on opposite sides of the base, the housing is made in the form of a glass, on the outer generatrix of which tracks are made that can interact with pores when installing the housing on the base and on the inner surface of the glass there is an annular protrusion, wherein the rods are arranged fiksir5Sch) impeding elements, wherein the device is further provided with abutment defined on the basis of the roller and the plate in contact with the end faces of the housing when it is installed on the base.

Due to the fact that the casing is mounted on the base rollers, it can be easily removed and the installation of parts (assemblies) in the casing is carried out at a specially equipped place using mounting elements, which is very convenient and enhances the installation accuracy and, consequently, processing. After the exhibition of parts (assemblies) in the case, it is installed on the base fixed on the table of the drilling machine, after which the holes are processed.

When conducting patent research, no solutions were found that are identical to the declared one, and therefore, the claimed utility model meets the criterion of “novelty.

We believe that the information presented in the application materials is sufficient for the practical implementation of the utility model.

The essence of the utility model is illustrated by graphic materials on which:

in FIG. 1 - a device for processing holes, a General view;

in FIG. 2 - a device for processing holes, side view;

the device for processing holes consists of a base 1 with elements 2 for its installation on the table of the drilling machine.

On the basis of 1, on its two sides in pairs, on the axles 3 mounted bearings 4, made in the form of bearings. On the other two sides of the base, an axial roller 5 is preferably mounted opposite each other, and on the other hand there is a latch 6 that can be moved from the handle 7. On the base 1, a plate 8 is also fixed, which together with the axial roller 5 serves to determine the position of the housing 9 during installation its support 4.

The housing 9 is made in the form of a cup, on the outer generatrix of which there are tracks 10 for contact with the supports 4, and in the cavity there is an annular protrusion 11. In the protrusion 11 holes are made (at least three are not indicated by the position) to install the axes 12, the ends of which are made threaded.

A nut 13 is screwed onto one end of each axis, and a pressure cracker 14 is screwed onto the other.

In the cavity of the housing 4 there are completely elements (not shown) for installing and fixing the machined parts (assemblies), which are partially shown by a thin contour.

On one of the ends of the housing 9, holes 15 are made, which are designed to interact with the latch 6. The number of holes corresponds to the number of holes in the parts (nodes). The angles of the holes correspond to the angles of rotation of the housing 9.

On the generatrix of the housing 9, plates 16 are fixed, on each of which a sleeve 17 is installed for the passage of the cutting tool (drill, countersink, reamer) for machining the hole.

Each plate has a hole (not indicated by the position) for the passage of the latch 18 when installing parts (assemblies) in the housing 9.

Device for processing holes works as follows.

We consider the operation of the device using the example of drilling holes for the connecting pin of nodes (for example, rocking chairs and levers).

ch0 /

Installation assembly units (nodes) in the housing 9 is carried out, as a rule, on a table or workbench.

When installing nodes in the housing, additional locking elements can be used to determine their relative position. The nodes can be fixed in the mounting unit, and the latter is installed in the housing 9 on the installation base elements. The latches 18 and the clamping crackers 14 allow for more accurate installation of nodes in the housing 9.

After fixing the parts (nodes) in the housing 9, the latter is placed on the base 1, mounted on the table of the drilling machine.

The housing 9 with the tracks 10 is mounted on the supports 4 so that its ends are located between the thrust roller 5 and the plate 8. This installation allows the housing 9 to make only a rotation movement about its axis, but excludes its movement in the axial direction, which ensures high accuracy of knowing the housing when processing holes.

After installing the housing 9 on the base 1, rotate the housing until the latch 6 enters one of the holes 15. Cornus 9 is fixed from rotation and is set to the working position for drilling the hole. Turn on the rotation of the spindle of the drilling machine and drill a hole for the connecting pin of two nodes (rocking chair and lever). If necessary, after the drilling is completed, the hole is drilled and reamed.

Then, by turning the handle 7, the latch 6 is withdrawn from the hole 15 and the housing 9 is rotated until the latch 6 enters the next hole 15 and then the processing cycle for the next hole is repeated. Next, the operations are repeated until all holes have been machined.

After finishing processing all the holes, the case is removed from the base, the processed parts (units) are unlocked and removed from the case. Install new parts (y3jn.i) in the housing 9 and the cycle repeats.
