SU1237452A1 - Device for drilling holes in articles - Google Patents

Description

The invention relates to the machining of products, for example, in the form of films assembled in a kit, and can be used to drill the drive holes in a set of color separation photoforms used during pin-down installation and made of a transparent film material.

The aim of the invention is to improve the accuracy of the drilling depth.

FIG. 1 shows the kinematic diagram of the device in the non-operating - initial position; on . 2 - kinematic diagram of the device in the working - final position; in fig. 3 - drilling unit, general view.

The device consists of a spindle 1 mounted on a frame (not shown), mounted in two onorors 2 rolls, spaced B support caliper 3, on which the thrust washer 4 is rigidly fixed. Caliper 3 with spindle 1 are installed with the possibility of vertical reciprocating axial moving relative to the housing 5 by means of a rack and pinion gear 6 from the handle 7 attached to the shaft 8.

In the non-working position, the caliper 3 with the spindle 1 is sent upwards with the aid of ripy- 9.

The spindle 1 is driven to rotate from an electric motor mounted on the frame K) through a clinoreme gear 11 connected by means of slides w, it is equipped with pin 1.

The body 5 is axially movable parallel to the axis and the pindel 1 is equipped with a spindle spring 14 via a rod 14, on which the support pressure bar 15, y.iep is firmly fixed in the upper (non-working) position by the spring 13 ., ustapovlepmogs on the rod 4, when it interacts with the) pu washer 4.

Adjustable Uior 17, made in the form of nuts and locknuts, ustanazo.chei ka rod 14 on its threaded part.

Billets in the form of a set of drink-split pho frames are stirred at crgo. 18.

The device works as follows.

Operator. Variable above the table 18 PP directed to a device (not shown) for drilling, sets it above the workpieces 19 and fixes it in the desired position relative to the working surface of the table 18 (the latches in Figures i - 3 are not shown).

Then it turns on the electric / ... motor. K), from which, through the V-belt transmission 11, the rotation of the width 1 is turned. By rotating the handle 7, the spring 9 overcomes the force by turning the shaft 8. At the same time, the rotational movement from the shaft 8 through the pinion transmission 6 sings the underwear change suppo | .gta

3, the mountain begins to descend along with the first task 1.

When the caliper 3 is lowered, the thrust washer 4 rigidly connected with it departs from the fixed unor 16. In this case, the transverse bar 15 fixed on the 1st thread 14 held in the upper position by the thrust washer 4 under the action of the spring 13 is lowered together with the rod 14 and presses the set of blanks 19 to the working surface of the table 18 before the superposed (not shown) occupies the working position.

The further downward rotation of the spindle 1 takes place until the sighe torn uiori th washer 4 touches the adjustable stop 17.

The adjustable stop 17 is set in such a way that when the desired drilling depth is reached, the feed of the drill 1 stops.

The specified drilling depth is adjusted by setting the size between the bottom end of the stop, the 4-piece in the initial position (when the washer 4 interacts with the fixed notch stop 16) and the adjustable 17

To return the device to its initial position, the operato turns the handle 7 to the opposite side and turns off the engine I).
