Description

STAND FOR STONE PROCESSING MACHINE, more particularly SONDERE A CORE DRILL

The invention relates to a stator for an Steinbearbeitungsma¬ machine, in particular a core drill, proceeds with a support rail and a height-adjustably guided on the carriage with a tool holder on which a drive unit and a rotationally connected to the latter tool is fastened, the turning axis parallel to the support rail and the advancing movement by adjusting the die holder taken along Trag¬ rail.

In a generic core drilling machine according to the patent EP-B l 0321395 the support rail is vertically or at an angle to the vertical be¬ voted on the floor or the like. At this rail, a holding element is arranged adjustable in height, on which a formed as an electric motor drive unit is attached. (Trephine) can be flange-mounted via a coupling device to the drive shaft of this electric motor then a coaxial core or hollow drill. Due to the usually generated by hand via a lever feed movement is this holding member and pushed forward with it the ver¬ by the electric motor into rotation sat core drill along its rotation axis and causes a section of a cylindrical hole in a Beton¬ or rock ground or the like. The disadvantage here is that the gesam¬ te mounting rail must be raised when replacing or a lengthening of the core drill so that the old core drill can be taken down and a new one is used.

The object of the present invention is in contrast to provide a stand for a stone working machine of the initially described type, by means of which a fast Ver¬ lengthening or a change of can be coupled to it a tool enables and this stand still tion, a very stable holding of it attachable tool provides.

According to the invention the task is solved in that the Werk¬ generating holder is held by a pivoting device on the slide, wherein by means of said pivot device, the tool holder, however in the processing position is removably transversely to the tool axis of rotation pivoted away and / or from the carriage, this tool to the mounting rail by means of the pivoting device fixable is.

In a very advantageous solution, the two pivot means parallel to the supporting rail extending, in the carriage of the axes arranged on nebeneinan¬ which, individually or together with the Werkeughalterung in or can be brought out of engagement.

With this inventive structure of the stator in a considerable simplification of the operation and manipulation of the rotatably mounted to this tool, in particular a core drill is obtained. Thus, the tool can be extended without that the stand has to be detached from and placed on the hand, is ensured, moreover, that the elongated tool can again be mounted in the same position as the previous consumed on the stand.

Embodiments of the invention and further advantages dersel¬ ben are explained in detail below with reference to the drawing. It shows:

1 is a side view of a stand according to the invention, Figure 2 is a plan view of the stand according to the Figure 1, Figure 3 shows an enlarged longitudinal section through the Schwenkeinrich¬ processing of the tool holder according to the Figures 1 and 4 is a front view of a variant embodiment of a inventive stand.

Fig. L shows a stand 10 for a stone working machine, which is executed in the present embodiment as so-called universal core drill. This stand 10 consists we¬ sentlichen of a carriage 20, an these leading Trag¬ rail 12, a latter-holding via a hinge 14 support leg 15 and two supporting elements 17 which hingedly at the upper end to a clampable on the mounting rail 12 the guide cams 27 and are pivotally held on the rear side of the supporting foot 15 at the lower end. At the height-adjustably guided on the carrier rail 12 carriage 20 is a tool holder 25 is mounted on which a drive unit 19, eg., A drilling motor, is fixed by means of a clamping device 25 '. This drive unit 19 has a motor shaft 26 to which a drill tool, represented as a core 1 8 is coupled an¬ below via a coupling 21, as is explained in detail for example in the patent EP-Bl 0,321,395. The axis of rotation 18 'of the latter extends parallel to the support rail 12 and the advancing movement of Werk¬ tool 18 is effected by a displacement of the tool holder 25 along the support rail 12 from the stator 10. The tool is rotated for that purpose by the drive unit 19 with a corresponding rotation speed and by an advancement in the axial direction of the core drill of this creates an annular cutout in which the support surface 11 forming the like or concrete floor.

According to the invention, the tool holder 25 via a swiveling device 30 on the carriage 20 is held, wherein by means of said swivel means 30, the tool holder 25 transversely generating rotational axis to Werk¬ 18 'can be pivoted away and / or from the carriage 20 weg¬ is detachable, however, in the working position of this tool 18 is fixable to the mounting rail 12 by means of the pivoting device 30th

The carriage 20 is advantageous in self-locking of the rail 12 Trag¬ rails 13 formed performed and it is moved via a manually operable feeding means along this guideway 12th From this feed device only just a via a lever or the like, movable axis of rotation 21 can be seen, which is non-rotatably connected to a pinion, which reached a arranged on the front side of the support rail 12 rack 16 in Ein¬ is and as it rotates a height adjustment of the carriage 20 causes.

The carrier rail 12 can be pivoted in the other around the vorge the support foot 15 provided for the joint 14, for example to a position P12, whereby the direction of tool feed movement with respect to the support surface 11 by the support foot 15 by a between 90 ° - as shown - and approximately 15 ° definable angle einstell¬ bar. Thus can be, for example, in a concrete floor an oblique bore with a diameter corresponding to the outdoor milling diameter of the core drill. The support leg 15 is provided fer¬ nerhin with leveling screws 15 ', with which the support rail 12 and thus adjust the direction of drilling of the core drill to the support surface 11 can be accurately. According to the Fig. 2, the carriage is formed in cross-section U-conveyor mig 20 and it has laterally two guide pins 23 which engage in the mutually opposed rails 13 on the carrier rail 12 while inner side at least on one rail slat perpendicular are adjustable to the support rail 12th This adjustability of the guide pin 23, the force required for the displacement of the carriage may be set as desired according to the twentieth this setting is advantageously chosen so that the carriage is guided self-locking in this support rail, if the drive unit is not mounted.

The pivoting means 30 includes two parallel to the support rail 12 extending, arranged side by side in the carriage 20 axles 32. which can be brought individually or together with the Werkeughalterung in or out of engagement. This side of the Werkzeughalte¬ tion 25 arranged axes 32 permit pivoting away of the tool holder 25 from the processing position Pl from both sides by an angle of approximately 180 ° each in a tool releasing position P2, and P3, as a result, the ange¬ pointed tool 18 , which is located for example in a bore, can be freely lifted vertically upward without the stator have to be carried away. The Werk¬ can imaging holder case optionally be swiveled on one or the other side, and the pivot plane is located senk¬ right to the rotation axis 1 8 'of the tool 18th

In this top view the two supporting elements 17 are further er¬ arranged, which are held on the one hand on the supporting foot 15 and on the other hand to the guide cam 27th The guide cam 27 is likewise guided in guides if the support rail 12 adjustable in height and this guide cam 27 clamp in a predetermined position by means of a screw extending therethrough can be 28th

The partial clarified in Fig.3 axis 32 of Schwenkein¬ device 30 has in each case two coaxially in the carriage 20 disposed axle parts 33, 34 which have, at the each end of each ten zugekehr- an opposing external threads 33 ', 34', which in a rotatably guided in the carriage 20 nut are slidably retained 35 and in each case matingly engage a bore 36, 37 of the slide 20 engaging around the tool holder 25 or out of bore 36, are pushed out 37, the latter being slightly conical and thus the axle parts 33 are, 34 firmly held positively therein. This axle parts 33, 34 are formed with the exception of the thread equal to and axially adjustable in a symmetrical An¬ order to nut 35 in the carriage 20th Moreover, they are secured against rotation in a respective guide part 39 and arranged them are also holes 41 for the purpose of Schmie¬ tion associated with their guide surfaces.

In the position shown, the axis 32 is brought out of engagement and thereby dissolved tool holder 25 can be pivoted about the other, not shown, axis 32 Accordingly, if this is engaged. These axes 32 are therefore used alternatively as a pivot axis of the tool holder 25th Upon release of both axes, the tool holder can be removed in total 25 from the carriage 20 and thus from the mounting rail 12th The nut 35 is accessible from the outside and can be rotated by hand in one or other direction.

According to the figure 4 is a fastened to this by means of a clamp 42 additional rail 40 is provided, for example in mounting a horizonta¬ len hole in a wall or the like to the vertically disposed in the present case mounting rail 12th At this cross-section advantageously the same as the support rail 12 formed support rail 40 is, in turn, the carriage 20 longitudinal displaceably guided on the latter and the tool holder 25 mounted on a pivoting device 30th The tool holder 25 may be pivoted transversely in detail um¬ prescribed pivot means 30 to the axis of rotation horizontally oriented tool according to the invention by these above. The clamp 42 has a base portion 43 which may be adjustable in height out on the support rail 12 and is fixed to this in any desired position. By means of this clamp 42 can thus be 40 as shown in the support rail but arranged in an inclined position to a vertical or horizontal. On the base part 43, a clamping piece 44 is held rotatably with a perpendicular to the support rail 12, erstrek- kenden axis of rotation, provided that the base is dissolved 43 from the mounting rail, whereas in the bewirk¬ by screws 45 th fixed position is also the clamping piece 44 against rotation secured. The latter has a guide track 47, in which the carrier rail is guided longitudinally displaceably and 40 can be fixed by means of a clamping jaw 48 and a screw 46th

The stand and especially the pivoting device could of course be implemented in other construction. With the illustrated embodiment, the present invention is not demonstrated sufficiently.
