SU26165A1 - Multi-spindle drilling machine for machining cardan drives - Google Patents

Description

A multi-spindle drilling machine for machining strips of card machines is proposed, in which a drum is used to communicate the movement of the supor, which is equipped with protrusions on the end to move the support along the frame and on the side surface with teeth to move the frame with the treated strap in the direction perpendicular to the movement of the support.

In FIG. 1 shows the front view of the proposed machine; FIG. 2 is a side view of it; FIG. 3-view it in the plan. In the guides 1 of the frame 2 of the proposed machine (Figs. 1 and 2), a support 3 is placed, carrying the frame 23, in which the treated strap is clamped with the help of thumb 24 (Fig. 3). To inform the caliper of movement along the d-anina, the latter is provided in its lower part by a process 46 (Fig. 1), sliding along the projections of the drum 18, which is rotated periodically with the help of the rod 20 and the levers 19 and 19 of which are articulated the center b, wedged on the shaft 5. The latter is placed in the bearings 4 of the bed 2 and is rotated from the pulley 11 by the shaft 10, the worm gear 8-9 (Fig. 2 and 3) and the gear coupling 32, one of the halves of which Zana with worm wheel 8, free sitting on the shaft 5.

In order to move in perpendicular pnо a suporu direction of the frame 23, it is seated on curved guide plates (Fig. 2) and provided with a rack 26 for engaging with a pawl of a system of levers 28, driven by a pusher 27, receiving its movement from the teeth 22 on the side the surface of the drum 18 (Fig. 1). The lever 35 (Fig. 2) is designed to reverse the frame, and it is pre-released with a handle 33 ,. spring loaded retaining dog 34.

Two medium spindles 43 of the machine get rotation from shaft 11, by means of pulley 12 on shaft 10, tongs 14.15 and belt gear 13, and two extreme spindles from first through belt gear 17 and pulleys 16 (Fig. 1). The feed of spindles is made by a crutch 42 (Fig. 2) connected by a rod 41 to a slider 44, vertically moved by an eccentric 7 of shaft 5, and there are several holes in the arm 42 that vary along the distance from the swing axis to change the feed amount x

Before starting to drill, the drills 21 are guided by conductor sleeves 3 & mounted on levers 37 seated on a common axis 38 (Fig. 2). Last connected to the spring lever 39 (Fig. 3),

with the free end pressing against the eccentric 40 mounted on the shaft 5. After the frame 23 is fully moved, it rests on the finger 29 and, acting on its further advancement, rotates the lever 30 (FIG. 2), which releases the lever 31. The last action of the spring (on the drawing is not indicated) is rotated together with the roller on which it is fixed and withdraws one of the halves of the coupling 32 from the clutch, thereby separating the drive from the shaft 5 (Fig. 3). After that, by the lever indicated above, the frame 23 returns to its original position and, after removing the finished bar, the next one is fixed.

The subject matter of the invention.
