Description

I The invention can be used in: machine-tool construction when machining products with the use of copying devices. Mechanical processing devices are known that contain a longitudinally moving support installed on a base, carrying a cross table with a spindle head and the axchism of movement of table carriages on the table. to given coordinates, j Mechanisms for re-paving carriages of Creo-JBoro table, consisting on a tunable mechanical builder and flat copy machines, are complex, the movement of the rel tool bore and tuned operations were carried out by different motors, which creates inconvenience obsruzhivanni. In order to simplify the construction and ease of maintenance, the mechanism in each device is moved by each of the cables made in the form of a roller mounted on the base, in which the groove is attached to the sleeve fixed on the roller of the hub of the corresponding carriage. -% of which the carriage is equipped with a base mounted installation mechanism for moving the “1”, including a self-braking worm with a personal gear connected with the corresponding roller. FIG. 1 shows the proposed device; roystvo, transverse section (section A-A; Fig. 2); in fig. 2 - the same in terms of; Fig. 3 is a sectional view of Fig. 1. The device comprises a base 1, on the longitudinal guides 2 of which a longitudinal caliper 3 with a drive 4. is installed. A cross table consisting of a transverse 5 and a vertical 6 carriage is installed in the slots of the longitudinal caliper . The spindle head is fixed on the vertical carriage ;; The device is equipped with mechanisms for moving the carriages in the transverse and vertical direction. The carriage movement mechanism in the transverse direction consists of a gearbox 8, a roller 9 supported on one side against a support 10 with an axial retainer 11. Scroll roller. On the other hand, the roller is associated with the BB. The shaft of the mechanism 12 .1

 adjusting movements containing the automatic worm gear 13 and / 14 flywheel

On the roller 9, a groove is made, which is generally oblique to the generator g of the cylinder, depending on the required trajectory of the spindle head along the corresponding axis of coordinates. The groove of the shaft enters the protrusion of the sleeve 15, rigidly connected to the gear wheel, 16 , .,ten

Gear in the axial direction is fixed relative to the gear housing 8, mounted on a longitudinal support, and connected; with a gear wheel of a bevel gear 17, which travels through a guitar to the fuzzy gears of a cylindrical gear 18, which changes the copying scale, a threaded sleeve 19, a running drive 20, and a cross carriage 5.j

The mechanism for moving the vertical carriage 6 contains a roller 21, the protrusion of the sleeve 22 interacts with the Koropord groove, rigidly; connected to a conical bristle 23.

The cushion is associated with the mechanical adjustments of the movements of the vertical carriage 24, having 23 self-braking worm gear 25, Gear 23 connected with bevel gear 28; transferring the movement of the guitar to the guitar of interchangeable gears 2T I slotted sleeve 28, a fixed relative to the j 30-gear body. 29, fortified; : .. longitudinal caliper 3, Next movement | transmits the slotted SJ 30, the Ionic I gear train 31, the xoijoeorvry to the screw 32, the threaded sleeve 33 and the vertical carriage 35: ka 6, on which the headstock 7 strengthened.

Drive 4 mix longitudinal caliper 3 together with gears transverse 8 and vertical 29 peremegtseniya. At the same time, the protrusion of the sleeve 15, which is located in the groove of the non-pivot roller 9, moving along the latter, rotates the gear 16 of the gearbox 8 by an angle depending on the position of the groove on the roller 9, and leads to | the movement of the transmission 17, 18 sleeve 19, running AIt 20 and the cross carriage 5.

Similarly, from the roller 21 through the gears 26, 27, the slotted bushing 28, the gear 31, the screw 32 and the threaded bushing, 33 the movement is transmitted to the vertical: carriage 6.

To adjust the initial position of the spindle head by moving the longitudinal caliper 3, the required position along the corresponding coordinate is reached. Then manually through the worm gear

25, roller 21, gears 26, 27, splined shaft 30, gear 25, lead screw 32 and sleeve 33 move the vertical carriage 6,,. . ., /. -;

Flywheel 14 is set in motion by a worm gear / 13 driven by the mechanics of the transfer: still cross-carriage, 5-cross tola. ,
