Definitions
- the invention is based on an insert tool and a tendon clamping system with a rotationally drivable, disk-shaped hub according to the preamble of claim 1.
- Disc-shaped insertion tools such as Grinding or
- Cutting disks for angle grinders usually consist of a bonded abrasive and have a central circular recess, via which the insert tool can be attached to an angle grinder spindle in a non-positive manner in the circumferential direction and positively in the axial direction.
- Both insert tools are known which have a reinforcement made of sheet metal in the region of the recess, and tools without a reinforcement.
- the invention is based on an insert tool with a rotationally drivable, disk-shaped hub and with one arranged in particular in a radially outer region
- Abrasives in particular for a cutting disc, a grinding disc, a grinding disc, a cutting disc, an abrasive paper, etc.
- the hub have at least one axially extending, eccentrically arranged receptacle for a functional element of a quick-action clamping system formed by a bolt, wherein a shape of the bolt can have a Q that appears to be useful to a person skilled in the art, such as, for example circular, elliptical, triangular, square or polygonal cross-section etc.
- a shape of the bolt can have a Q that appears to be useful to a person skilled in the art, such as, for example circular, elliptical, triangular, square or polygonal cross-section etc.
- the axial extent of the receptacle preferably being greater than a protrusion of the functional element or the bolt over the hub.
- a protective function can always be guaranteed by exchanging the hub when changing the insert tool.
- the receptacle also forms a flat system for the functional element, which advantageously cuts the hub into the functional element is. Wear of the functional element under the influence of abrasive dust, such as corundum dust in particular, can be reduced since the receptacle molded onto the hub largely covers the functional element. '' The hub can be safely detached from the functional element at any time. A premature loss due to the incision Wear on the functional element can be avoided and service intervals can be extended. Furthermore, with the receptacle extending in the axial direction, a reverse installation of the insert tool in a tool holder can advantageously be avoided. Furthermore, the operator can immediately recognize a correct assembly side from the mount, which is particularly important in the case of tools that are tied to the direction of rotation.
- the receptacle can be made in one piece or in several parts with the hub. If the holder is made of several parts with the hub, different materials can be used, e.g. Metal for the hub and plastic for the receptacle etc. Particularly advantageously, however, the receptacle is made in one piece with the hub. A particularly stable receptacle with a particularly advantageous protection of the functional element against mechanical damage can be achieved.
- the receptacle can be molded onto the hub in a particularly simple and cost-effective manner in a deep-drawing process.
- the receptacle has a closed side wall, a particularly rigid shape can be achieved with advantageous protection of the functional element, and large moments can be transmitted via the receptacle.
- the side wall is slotted. In the case of a slotted side wall, tolerances can advantageously be compensated for by elastic deformations and play between the receptacle and the functional element can simply be avoided. Furthermore, dirt that collects in the receptacle can through the slot when inserting the functional element can be easily removed.
- the receptacle has a round cross-sectional area.
- the functional element which engages in the receptacle can advantageously be designed with a round cross-sectional area.
- the functional element can be produced inexpensively and tilting of the functional element in the receptacle can be reliably avoided.
- the receptacle has at least one through opening on its end face pointing in the axial direction. Dirt and abrasive dust, which is located in the receptacle, can simply be pushed by the functional element through the passage opening when the functional element is inserted into the receptacle and removed from the receptacle.
- the hub is arranged, further protection of the functional elements can be achieved through the shape of the hub.
- the receptacle is set back in relation to a disk plane, which can advantageously reduce the risk of a possible collision with a workpiece.
- FIG. 2 shows an insert tool according to the invention
- FIG. 3 shows an enlarged view of a hub mounted in the angle grinder without abrasive
- FIG. 1 shows an angle grinder 48 from above with an electric motor, not shown, which is mounted in a housing 54.
- the angle grinder 48 can be guided via a first handle 56, which extends in the longitudinal direction and is integrated in the housing 54 on the side facing away from an insert tool, and via a second handle 60 which is attached to a gear housing 58 in the region of the insert tool and extends transversely to the longitudinal direction.
- FIG. 2 shows the insert tool from FIG. 1 in the disassembled state.
- the insert tool has a rotatably drivable, disk-shaped hub 10 made of sheet steel, to which an abrasive 12 forming a grinding wheel is fastened in the radially outer region.
- the abrasive 12 is essentially composed of glass fiber mats, abrasive abrasive bodies and binders, which are pressed together to form a solid disc, the binder having been cured in a heat process.
- the hub 10 has an inner region 40 and an outer region 62, the inner region 40 being arranged sunk relative to the outer region 62 (FIG. 3).
- the hub 10 In its outer region 62, the hub 10 has slot-shaped recesses 64 which are designed to be open radially outward.
- the recesses 64 have a constant width and protrude radially inwards to the inner region 40.
- recesses 66, 68, 70 are made for fastening the insert tool via a quick-action clamping system.
- the recesses 66, 68, 70 are arranged evenly distributed in the circumferential direction 50, 52 and have a narrow, elongated area counter to a direction of rotation 46, which is adjoined by a broad, oval area.
- three hold-down devices 42, 44 pass through the recesses 66, 68, 70 in the axial direction 14 and fix the hub 10 in the axial direction to a tool holder.
- a circular recess 72 for centering the insert tool introduced to a collar 74 of the tool holder of the angle grinder 48.
- the hub 10 has three receptacles 16, 18, 20 which are uniformly distributed in the circumferential direction 50, 52 and extend in the axial direction and are arranged off-center.
- Functional elements of the quick-action clamping system formed by bolts engage in the receptacles 16, 18, 20 in a form-fitting manner.
- the insert tool can be operatively connected to the quick-action clamping device via the bolts movably mounted against a spring element, which snap into the receptacles 16, 18, 20 in an operating position of the insert tool and fix the insert tool in the circumferential direction 50, 52 in a form-fitting manner.
- the receptacles 16, 18, 20, which have a round cross section, are made in one piece with the hub 10, and each have a self-contained side wall 22, 24, 26.
- the receptacles 16, 18, 20 are molded onto the hub 10 in a deep-drawing process.
- the receptacles 16, 18, 20 each have a through-opening 34, 36, 38 on their end faces 28, 30, 32, which face in the axial direction 14.
- the receptacles 16, 18, 20, which are opposite the direction of rotation 46 in front of the three hold-down devices 42 , 44 are arranged, the three hold-downs 42, 44 protrude in the axial direction 14. With a rotating drive in the direction of rotation 46, the three hold-downs 42, 44 are thus located a slipstream of the cup-shaped receptacles 18, 20 and are protected by them.
