Description

Semiautomatic machines for processing skis are known, made in the form of a stationary table with pneumatic clamps for workpieces being machined and a carriage with a milling spindle moving along it. On these semiautomatic machines it is possible to process only one-sided blank, which slows down the process of its processing from all sides.

The proposed semi-automatic milling machine makes it possible to handle all sides of the skis, except the pointed toe and the end of the heel. For simultaneous processing of the bottom and the guide groove at one workpiece and sides, top and fillets, the ridge at the second table of the machine is equipped with two pairs of clamps for placing two workpieces, one bottom up and the other top up, and eleven milling spindles are mounted on the carriage Aided by fixed copy lines in the transverse direction to the workpieces.

Of the total milling spindles, five spindles are mounted horizontally; three of these spindles are machining the bottom and the ski guide groove, and two are the top of the skis. Six other spindles are mounted vertically, four of which process the ridges of the ski ridge and two of their sides.

In the pneumatic clamps of the semi-automatic, pneumatic chambers with elastic movable diaphragms, which interact by means of a transfer lever with the movable jaw of the clamp, are used.

FIG. depicts a fixed semi-automatic table, side view; pas figs. 2 - top view; in fig. 3 - carriage, view from the front side of the table; in fig. 4 - the same plan view; in fig. 5 —slides with two vertical milling shpindles for milling fillets of the ski ridge, side view; in fig. 6 is one of two levers carrying a horizontal milling spindle for machining the top of the skis, side view; in fig. 7 - two slides with vertical milling spindles for machining the sides of the skis, side view; in fig. 8 is a vertical section of one of the pneumatic table clamps; in fig. 9, 10, 11, and 12 show the sequential layout of six vertical milling spindles when milling the sides and fillets of the ridge of the skis.

The semi-automatic milling machine consists of a fixed / fixed table 2 (Fig. 2), on which are installed: a pair of pneumatic no. 114176-2 -

tack clamps 3 for securing the workpiece 4, facing upwards upside down; a pair of other pneumatic clips 5 for fastening the other billet 6 which faces upwardly upwards; guide rails 7 (Fig. 3 and 4) and a ruler, and the carriage 8, which is moved along the rails by means of rollers 9 and a drive (not shown in the drawing).

On the carriage, there are eleven milling chucks, moved by means of fixed copying rulers in the transverse direction to the skis.

Three spindles 10, 11, and 12 (Fig. 3 and 4) for machining the bottom and guiding grooves of the skis at workpiece 4 by means of cutters 13 and 14, together with the driving motors 15, 16 and 17, are mounted horizontally on three rails 18, 19 and 20 moved vertically by its weight. Rollers 21 are mounted on the sled, running in fixed copying lines 22.

Two shpindles 23 and 24 (Figs. 3, 4 and 6) for machining the top of the skis at the workpiece 6 by means of cutters 25 together with driving motors 26 and 27 are mounted horizontally on levers 28 and 29 swinging on horizontal axes 30 (Fig. 6 ). The levers are provided with rollers 31 which are driven around in fixed copying lines 32.

Four spindles 33, 34, 35 and 36 (Figs. 3, 4 and 5) for treating fillets are the ridge of the ski at workpiece 6 by means of cutters 37 together with driving motors 38 and 39 are installed vertically and in pairs on two spring-loaded slides 40 and 4 moved horizontally towards each other by means of rollers 42 rolling around the fixed copier lines 43.

Two pieces 44 and 45 (Fig. 4 and 7) for processing the sides of the skis at the workpiece 6 by means of cutters 46 (Figs. 3, 4 and 7), together with electric motors 47 and 48, are mounted vertically on two spring-loaded skids 49 and 50 moved horizontally towards each other and connected by means of tg 51 and rocker arms 52. The slide 50 is provided with a roller 53 running in a fixed copying ruler 54.

In the pneumatic clips of the skis blanks, pneumatic chambers 55 (FIG. 8) are applied with elastic movable membranes.) 6, which cooperate with a palm 57 attached to them with a transfer lever 58, which moves the movable sponge 59 of these clips.

The compressed air is supplied to the chambers and the air is exhausted from the chambers by means of a manually switched valve 60 (Fig. 1) connected by pipelines with a source of compressed air and to nipples 61 pneumatic chambers.

On the table 2 there are buttons 62 (FIG. 1) for starting and stopping the drive motors and the drive for moving the carriage.

Work milling semi-automatic proceeds as follows.

At the beginning of the work, the workpiece 4 is fixed in the pneumatic clamps 3, bottom-up, leaving the clamps 5 without the workpiece, after which the electric motors of the spindle and drive are turned on. When the carriage 8 is moved in the direction of arrow A (Fig. 9), the bottom and the ski guide groove are machined. After that, the workpiece 4 is removed, the carriage is retracted to the extreme right position, the processed workpiece 4 is installed in the pneumatic clips 5 for the workpiece 6 upwards, and the new workpiece 4 is installed in the clips 3, after which the electric motors of the spindle and carriage drive are turned on. When the carriage is moved, the bottom and guide grooves are machined at workpiece 4, and at the same time, the sides, top and fillers of the ski paddle at workpiece 6 are machined in the sequence shown in FIG. 9, 10, 11 and 12, after which the process is repeated.
