Definitions
- the invention relates to a tool holder according to the preamble of claim 1.
- Tool holders designed as hand scrapers which have a base body with two sheet metal shells.
- the sheet metal shells are connected by a screw connection. If the screw connection is loosened using a tool, for example using a screwdriver, a scraper blade can be inserted between the sheet metal shells and clamped between the sheet metal shells using the screw connection.
- the invention is based on a tool holder me: a basic body formed from at least one plate, which has at least one detachable fastening means for fastening a tool.
- the fastening means be formed by a latching means which can be moved from its latched position into a position releasing the tool without tools. It is possible to achieve a particularly convenient and in particular with a plurality of connected sheet metal plates which extend in the machining direction, a particularly stable tool holder which is advantageously suitable for machine use. In principle, however, the solution according to the invention can also be advantageously used with hand-held tool holders.
- the solution according to the invention is particularly suitable for fastening scraper blades which are driven in a reciprocating manner, but in principle it is also conceivable to fasten other tools which appear to the person skilled in the art to be useful in the tool holder according to the invention, for example filing tools, grinding tools and without additional brackets etc.
- sheet metal plates plates made of a different material are also conceivable, such as fiberglass, Teflon, etc.
- the sheet metal plates can be punched out economically or advantageously cut out by a laser cutting process, thereby avoiding additional tool costs for special manufacturing tools, such as punching tools can be. If the sheet metal plates are inseparably connected, it is advantageously possible to avoid loose individual parts.
- the basic body is formed from three sheet metal plates, namely from a cover plate, a middle plate and a bottom plate, a receiving area for the tool can easily be achieved between the bottom plate and the cover plate, and in particular the tool can be positively supported against the direction of processing on the middle plate , Large forces can be transferred to the tool via the middle plate arranged between the base plate and the cover plate.
- three metal plates instead of three metal plates, however, only one metal plate, two metal plates or more than three metal plates are conceivable.
- individual sheet metal plates can advantageously be used to form a stable body overall and still create individual, elastically deflectable areas for detachable detachable means, in particular by at least one fastening means or detent means on a partial area of a sheet metal plate, preferably cover plate or Base plate is arranged, which can be elastically deflected by hand without tools without tools, perpendicular to the sheet metal plate.
- a sheet metal plate preferably cover plate or Base plate is arranged, which can be elastically deflected by hand without tools without tools, perpendicular to the sheet metal plate.
- the partial area is advantageously laterally free by recesses and laterally delimited by cheeks which are firmly connected to an adjacent sheet metal plate, the tool can be supported perpendicular to the sheet metal plate without the partial area being deflected or stressed becomes.
- at least one sheet metal plate with a recess is advantageously carried out, through which the partial area can be loaded to release the fastening means. If the recess is at least finger-sized, the partial area can be loaded efficiently by this, for example with the thumb. A load on other components or other sheet metal plates and the increased effort required as a result can be avoided.
- At least one fastening means is molded onto a sheet metal plate, additional components, assembly effort and costs can be saved. In principle, however, it would also be conceivable for a fastening means to be formed by an additional component fastened to a sheet metal plate.
- At least one fastening means be formed by a sheet which points counter to the machining direction, as a result of which a particularly secure hold is achieved in the machining direction and independent loosening can be reliably avoided. A kind of barb can be reached.
- the metal plates may be connected appear reasonable force-fit, form-fitting and / or material-fit connections, such as by a rivet, a screw, a positive connection is produced by a forming process, adhesive bonding, etc.
- the sheet metal plates are spot welded, whereby the sheet metal plates can be permanently connected inexpensively without additional fasteners.
- spot welding can be used to create a section that can be deflected perpendicularly to the sheet metal plate in a structurally simple manner, specifically by excluding this section from welding spots,
- FIG. 4 the scraper blade holder from the side
- FIG. 7 shows a section along the line VII-VII in FIG. 6, 8 shows a middle plate of the doctor blade holder and FIG. 9 shows a base plate of the doctor blade holder.
- FIG. 1 shows an electric scraper 42 with an electric motor, not shown in a housing 44, with which a part of a holder can be moved back and forth with a translatory movement by means of a gear.
- a scraper blade holder according to the invention is fastened in the holder with a scraper blade 18.
- the scraper blade holder has a base body 10, which is constructed from three sheet metal plates 22, 24, 26, which are non-detachably connected via welding points 46, 48, 50, 52 and extend in the machining direction 20, namely from a cover plate, a middle plate and a base plate ( 2 to 9).
- the sheet metal plates 22, 24, 26 are cut out by a laser cutting method and are congruent from their outer contour except for one end face facing the scraper blade 18.
- the sheet metal plates 22, 24, 26 form a narrow shaft with an opening 54 for fastening in the holder of the electric scraper and a holding area for the scraper blade 18, which extends from the shaft to the scraper blade 18 in a V-shape outwards.
- the opening 54 has a greater length than its width and has a rounded contour in and against the machining direction 20, as a result of which "advantageous force transmission from the electric scraper 42 to the tool holder can be achieved
- Scraper blade 18 facing end has the sheet metal plate 24 or the middle plate has a recess 58 for receiving the doctor blade 18 between the sheet metal plates 22, 26 or between the cover plate and the base plate (FIGS. 2, 3 and 8).
- detachable fastening means 12, 14, 16 for fastening the scraper blade 18 are formed as latching means onto a partial area 28 of the sheet metal plate 22 or cover plate, which can be elastically deflected by hand without tools, in order to release the fastening means 12, 14, 16 , namely in the direction facing away from the sheet metal plate 26 or base plate.
- a fastening means 16 is arranged on a central axis of the base body 10 and is formed by a tab which points counter to the machining direction 20 and is exposed by a U-shaped recess 56, which is deflected in the direction of the sheet metal plate 26 or base plate and extends through the cutout 58 Sheet metal plate 24 or central plate and extends through a square recess 60 of the sheet metal plate 26 or base plate (FIGS. 6 and 7).
