unnome 2 for tool change. Tool shop 2 is expandable. In the decompressed state, the relative movement of the tool spindle 3 and tool magazine 2 in the latter can be made 1

This invention relates to multioperational machines for cold working of blanks.

The purpose of the invention is to reduce the tool change time.

The tool magazine can be unclamped when interacting with the relative spindle by moving the relative spindle. In the expanded state, with the relative motion of the tool spindle and tool magazine, the tool spindle can be inserted into it or removed from it.

In a multioperational machine, a quick tool change is possible, since the search from the tool tool occurs during machining with the tool previously found. The tool magazine is located outside the chip area, so that tool contamination is prevented, interfering edges, reception and transmission are performed by the spindle itself without creating a long path and needing to install additional drives.

It is preferable to keep the tool magazine stationary, while moving the tool spindle. Decompressing the tool magazine is done by moving the tool spindle to the tool magazine to from it.

The tool magazine can be equipped with two parallel guide tires, the ends of which, in an unopened state, are adjacent to each other and, between them, two parallel portions of the guide bars can be inserted in the unclamped state, and the circular track guides. This provides.

Both in unopened and uncompressed co-state. The possibility, during processing with one tool, to bring the next tool to the change position in the magazine, which is to the left or right of the unclamping point. In the transfer position in the unfolded state, movement of the tool in the magazine takes place only one position. one or two places, for example, are equipped with a hinge.

FIG. 1 shows a multi-operation machine for cutting workpieces with a side view; FIG. 2 is a view A of FIG. 1; FIG. 3 is a section BB in FIG. 1, the store in the working pole; in fig. 4 - the same. Shop in tool change position

The machine 1 is used for machining with the removal of workpieces, such as drilling, threading, milling, etc., and is equipped with tool shop 2, between HHCTpyMeHrcijibHbW. Magaain 2 and the manual spindle 3 can replace the corresponding tools 4, while ensuring a very short changeover time for the HHCTpyMeH-ij-a, bx agent that occurs during the processing of search in the store.

The multi-operation machine 1 can also be a frame 5, on the side of which the table 6 is fixed. securing the logging unit, and on the section of the workplace passing to the counterblock to the workplace, guides 7 horizons are fastened, and the horizontal sages along which the coordinate bands 8 can move parallel to the table 6 in the X direction, while the necessary for this purpose, the drive is placed in the frame 5 of the machine. Horizontal rails 9 are provided on rails 8 for rails, along which coordinate rails 10, which are part of the stand of machine 11, can move in direction Y by means of a drive. Rack 12 on front table 13 that faces stationary or rotatable in horizontal plane 6 is provided with vertical rails 14 for the spindle head 15, which carries the rotating tool spindle 3, the spindle head 15 can be moved up and down in the direction of the vertical axis Z with the help of the motor 16. In the spindle head 15, the rotating tool spindle 3 is also rotated from the main drive motor 17 mounted on a rack 12. The workpiece table 6 is rigid or movable in a horizontal plane so that at one end of the table the workpiece is processed and at this time at its other end the workpiece can be clamped With respect to it, the tool spindle 3 can move in all three perpendicular one to another coordinate axis X, Y, Z. The presented multi-operation machine 1 is equipped with a vertically positioned tool mental spindle 3, however, the signs characterizing the tool changer can be attributed to and to the multioperational machine whose tool spindle is located horizontally and / or at which the work table 6 moves along one of the three axes on the front and side parts of the machine base 5 there is a conveyor 18 dl for chips.

The tool magazine 2 is held stationary on the slide 8 moving in the X direction, placed in a horizontal plane so that relative to it the tool spindle 3 can move in two directions, namely along the Y and Z axes, which extend radially and along the longitudinal axis of the store. Tool magazine 2 (fig.Z and 4) has two parallel tires 19 and 20, which are located

They are placed at a constant distance from one another and form one continuous circumferential guide track, which has an oval shape. Guide

track may be another geometric shape. Along the track track 21, one after the other, tools 4 are clamped in parallel, which with the help of adapters 22 are guided like a slide and can be moved. The tools 4 (in FIGS. 1 and 2 a gripping cone 23 is shown) are thus held in adapters 22, with their cutting parts facing down.

The outer guide rail 20 is surrounded by a downwardly covering: a protective casing 24, which protects the tools 4 in the store 2 from contamination, for example, chips from the treatment area. Tools 4 with adapters 22 abut against each other, driven in motion along guide track 21 in one or both directions by means of a wheel 25 in the form of a chain sprocket through a drive motor 26, with two adjacent teeth of wheel 25 engaging a specific area of tool 4 or its adapter 22 and move the tool 4 along the guide track 21. The drive 26 of the tool magazine 2 is provided at the anti-spindle headstock 15 of the magazine.

The tool magazine 2 is positioned relative to the spindle head 15 so that the guide track 21 is then cut at position 27 when the tool spindle 3 is located at the tool change position (Fig. 4), in which the tool magazine 2 takes the unclamp position. In one of the working positions of the instrumental spindle 3, the instrumental mental magazine 2 takes the position of the search movement in which it is not expanded. In order for the tool magazine 2 to be able to assume both positions (Figs. 3 and 4), in place 27, both of its guide tires 19 and 20 are cut and made so that in the radial direction and the direction perpendicular to the course of the guide track 21, it is elastically deformed. that the ends 28 and 29 of the guide rails 19 and 20, which are located close to each other in the position of the search movement (Fig. 3), can go out from each other by a certain amount, i.e. The guide track 21 at this point 27 can be unfolded as a collet or lengthened. it

occurs (fig. 3 and 4) by means of an expansion mechanism 30, which has two expansion rods 31 and 32, which are movable in the supports 33 in the direction of the unclamping movement and whose external ends, for example, in the straight section of guide rails 19 and 20 are connected with them through the hinge 34.

The inner ends of the expanding rods 31 and 32 are provided with a roller, which can be engaged with the corresponding rocker guide 36 symmetrical with respect to the longitudinal axis of the magazine 2 of the rocker slide 37. The latter is rigidly connected to the post 12 and, like the oHaj, is driven by the motor 16 in motion in the Y direction with respect to the magazine 2. If the slide slider 37 is shifted relative to the position on FIGURE 3 to the right (FIG. 4), the expansion rods 31 and 32, and consequently also the longitudinal sections of the guide rails 19 and 20, which are elasticallyserved out from each other. Due to this, an uncoupling of the guide track 21 is created at the unclamping position 27; - At this, the unclamping value is chosen such that between two neighbors1 with ends 28 and 29 of the guide busbars T9 and 20 tools AL and 4R can accommodate an additional tool 4A,

A tool 2 that is to be stored in the tool magazine 2 at the tool change position is installed on two parallel straight or slightly parallel parallel auxiliary tires 38 and 39, which are held at the lower end of the spindle head 15. from tires 38 and 39 are made so that it is in the tool changing position in the gap of the decompressed guide track 21 form an addition to the continuously running tracker, e, they lie with their opposite ends 40 and 41, respectively: to the opposite opposite ends 28 and 29 of the guide rails 19 and 20, Sections of the guide rails 38 and 39 are mounted on the shank 42. on the projection 43 on the spindle head 15 in the vertical direction against the action pressure spring so that when the tool spindle 3 is disengaged from the tool

Volume 4Aj of the 3G and 39 tire tracks remains at the height of the direction of the youth track and holds this tool 4A.

The process of tool change in the working position of the tool spindle 3 or in the position of the search movement of the tool magazine 2 is as follows.

Clamped on table 6, the workpiece is machined by moving the tool spindle, if necessary, along all three axes of coordinates. FIG. 1 shows one of the working positions with spare lines. The tool spindle 3 can be fed in the Y and Z directions by dashed lines. With the corresponding tools 4, the segments of the tires 38 and 39 on the headstock are also captured. The position of the tool store 12 relative to the frame varies only in direction X.

To prepare the tool change during machining of the workpiece with the help of the corresponding tool 4 in the tool spindle 3, the magazine 2 performs a search movement, i.e. That tool 4, which is to be applied in the next processing of the workpiece, is brought to the next unclamping or transfer position, namely the position of the tool 4L or 4R.

When changing tools, the headstock 15 moves in the Z direction, the segments of the guide bars 38 and 39 are located at the height of the guide bars 19 to 2C of the guide track 21, In addition, the headstock 15 moves in the B direction Y to the magazine 2 and this movement can partially block the movement of Z. The last (FIG. 3) should be completed DEI:) in direction Z, because with the further movement of the centerpiece 15 in la unlimited: (. to shop 2 there is an unclamping, the guide track 21 s, using extension 1- of the mechanism 30. Secondary tires 19 and 20 and, therefore, j, guide track 21 exit each other at location 27, expanding and form a gap into which sections of guide pega 38 and 39 can be wedged with tool 4A, This way the o6pa3OMj track 21 is

the result of the movement of the spindle head 15 in the direction Y, so that you do not need to provide your own drive for unclenching. The rocker slider 37 can be provided in the area of the spindle head 15, In the tool change position (FIG. 4), in the unlocked position of tool magazine 2 , the sections along the busbars 38 and 39 again close, the decompressed guide track 21 by filling the gap "The segments of the guides zgan 38 and 39 are kept in the extended position.

In this case, the tool spindle 3 is moved upward along the Z axis by means of the spindle head 15 (Fig. 1), the tool spindle 3 is opened and the latter is uncoupled from the tools, t "1ent ,,

As the spindle head 15 moves upward, the relative movement of the segments of the guide tires 38 and 39 and the lower end of the Echindelnaya headstock 15 or its protrusion 50 occurs, the segments of the guide bars 38 and 39 are adjacent to the horizontal retaining stop, and the relative movement of the shank 42 and protrusion 43.

If the tool spindle 3 is not coupled to the tool 4A5, then the tool mag 2 or tools located in the guide track 21 are turned by one position j, i.e. one tool position in one direction or the other., tool 4L or 4R falls into place 27 of the transfer between segments of guide rails 38 to 39, then spindle head 15 moves down again, tool spindle 3 is collapsed with a new tool; volume 4L or 4R5 adheres to the former relative position of the segments of the guide rails 38 and 39 to the lower end of the spindle head 15 or the protrusion 43, while restoring the previous relative position,

For machining the workpiece with the help of a new tool 4L or 4R, spindle headstock 15 moves out of the tool magazine 2 in the Y direction, as the stitches 31 to 32 can be moved back to each other due to the directional action of diverging and directing Sch & 1k 19 to 20.

return to each other again, and a closed track YUSH track 21 is formed without stretching the tires 38 and 39. During the subsequent processing of the workpiece, a new movement can take place in magazine 2 to prepare the next tool in one of the positions that are near 27. Tools can be transported in the store with both closed and uncoupled guide tires.
