Description

The invention relates to a machine tool industry and can be used to supply a cutting fluid (coolant) to a working body, in particular, a cutting tool of a multi-operation machine, where the tool change is performed automatically.

A device for supplying a coolant to a cutting zone, preferably to a cutting tool of a multi-operation machine, is known, comprising a housing mounted on a spindle head and movable and fixed parts mounted on the movable part of the housing with the possibility of rotating the sleeve with the coolant outlet and mechanisms of rotation and fixation of the sleeve in a predetermined position. The angle of inclination of the outlet pipe is set by turning the movable ring with the help of an engine and rack and pinion. Concentric to the aforementioned ring, an additional ring is mounted, and the body has an open ring shape 1.

A disadvantage of the known device is the complexity of its design.

The purpose of the invention. The simplification of the design.

The goal is achieved by the fact that in the device for supplying coolant mainly to a cutting tool of a multioperational machine, comprising a housing mounted on the spindle head, consisting of moving and stationary parts, mounted on the movable part of the housing with the possibility of rotating the sleeve with the outlet nozzle for coolant and mechanism rotation and fixation of the sleeve in a predetermined position, the fixation mechanism is made in the form of a pinion mounted on the sleeve, which is engaged with it in the linkage of the rail mounted on the placed and the movable part of the housing is a lever, a wedge and an emphasis installed with the ability to interact respectively with the movable and stationary parts of the housing and with the lever, and the rotation mechanism is made in the form of a spring fixed at one end on the fixed part of the housing and the other at the tongue fixed on the hub of the anvil and mounted with the possibility of interaction with it of the screw placed on the jacket of the tool holder.

FIG. 1 shows a coolant supply device, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. 3; in fig. 6 is a section d-d in FIG. five; in fig. 7 is a view E of FIG. 1 (with the wedge retracted and the position of the rotatable sleeve fixed). The coolant device consists of a body mounted on the spindle head containing a stationary 1 and 2 moving parts, a bracket 3 mounted on the manipulator 4, with a wedge 5 mounted on it and an abutment 6. The stationary part 1 of the body is fixed on the spindle head 7, and The movable part 2 is mounted on two rolling pins, guides 8, which can be moved in the fixed part of the body. The movable part 2 moves relative to the fixed part 1 and is pressed against it by springs 9 placed on rolling pins 8, and

0 adjusted nuts 10. To the fixed part of the body with screws 11, an axis 12 is fastened, on which a rotary sleeve 13 is seated on one side, locked on the axis by a ring 14, and on the other side an angle 15 is screwed, connected to the feed line

5 coolant by means of flexible hose 16. On the rotary sleeve are placed the outlet nipple 17 and the stop 18. Screw 19, against which the stop 18 rests when installing the new tool, is placed on the shirt 20, which serves to transfer the tool fixed on the tool holder 21. On screw 19 has a locknut 22 to fix its position when adjusting for tool length. On the movable part of the housing there is a mechanism for fixing the rotatable sleeve, which includes a lever 23, which pivots about an axis 24 mounted on the movable part of the case and fixed to it by a ring 25. To one side of the lever 23 screws 26 secure the rail 27 and its other side rests

0 into the cup 28, mounted in the opening of the movable part of the body and pressed by the spring 29. On the rotary sleeve 13 there is a gear 30 mounted on it with screws 31. The gear 30 engages with the rail 27. The spring 32 is at one end

fixed on the axis 33 of the fixed part of the body, others on the axis 34 of the gear 30. Under the action of the spring, the stop 18 when changing the tool is pressed against the screw 19, and in its absence, the outlet nozzle 17 is pressed against the limiter 35 fixed to the moving part of the body with screws 36.

The device works as follows.

When changing tools, manipulator 4

is supplied to the headstock 7 and at

5, the wedge 5 assists for a certain distance the movable part 2 of the body from the stationary part 1. In this case, the stop 18 comes in contact with the screw 19 attached to the jacket 20 of the tool holder 21. At the end of the manipulator turn 4, the stop 6 presses the lever 23 and compressing the spring 29, raises the rail 27, withdrawing it from engagement with the gear 30 mounted on the rotary sleeve 13. The spring 32 fixed at one end on the sleeve 13 presses the stop 18 to the screw 19. In

5, the tool pulls out of the spindle under the action of the spring 32, the rotary sleeve rotates up to the stop by the nozzle 17 into the stop 35. When installing the new tool into the spindle, the tool comes into contact with the stop 18 with the screw and, tightening the spring 32, turns the sleeve 13 to the desired angle. In this position, the pivot sleeve is fixed when the manipulator is retracted to its original position. This removes the wedge 5 and the stop 18 is slightly removed from the screw 19, forming a small gap. Minor IMAGE, /, Figure 2

Fig. 10 of the pipe 17 along the axis of the spindle when removing the wedge 5 is taken into account when adjusting the length of the screw 19. The positioning of the screw 19 on the tool allows you to adjust the angle of rotation of the output pipe outside the machine. Thus, the use of the invention significantly simplifies the design of the device.
