The detacher includes a detachment body and a rotary part coupled to the detachment body, the rotary part includes a key protruding outward from the rotary part in a first horizontal direction, and the rotary part is configured to rotate about a central axis extending in the first horizontal direction.

The present invention discloses a detachable grinding disk for an electric grinder with high adhesion efficiency, the detachable grinding disk comprising: a plate part made of a circular metal plate; a sanding part on which a grinding member is formed so that one side of the plate part has a grinding surface; and a fastening part provided in a form of a through hole at a position of a central axis of the plate part to be easily fastened to the electric grinder, wherein the plate part is formed to have a gradual curvature in such a way that a convex surface of the gradual curvature is formed toward the sanding part, thereby enabling the detachable grinding disk to be attached to the electric grinder closely, elastically, and preventing overturning during high-speed rotation.

A device for automatically removing a grinding wheel from a grinding machine mounted on a manipulator is described. According to one embodiment, the device has the following: a support plate with a surface for depositing a grinding wheel; a movable clamping element that is raised in a first position with respect to the support plate; an actuator that is coupled to the clamping element and is configured to move the clamping element into a second position in which the clamping element is pressed against the support plate such that the grinding wheel is clamped between the support plate and clamping element; and a release element that is arranged in such a way relative to the support plate that the release element is actuated when the grinding wheel is placed on the surface of the support plate and is pressed against the latter. The release element and the actuator are coupled (directly or indirectly, electrically or mechanically) such that, when the release element is actuated, the actuator moves the clamping element from the first position into the second position.

A repositionable abrasive disc mounting assembly comprises a backup pad and a clamp assembly. The backup pad has a rotational axis of use and a major surface with projections extending outwardly therefrom. The backup pad further comprises an inwardly facing centrally disposed first fastening member, and also an outwardly facing centrally disposed second fastening member. The clamp assembly comprises inner and outer clamp members for securing an abrasive disc. The inner clamp member comprises an inwardly facing centrally disposed third fastening member adapted to repositionably engage the second fastening member in a discrete number of rotational orientations. The inner clamp member further comprises an outwardly facing centrally disposed fourth fastening member. The outer clamp member comprises an inwardly facing centrally disposed fifth fastening member adapted to securely engage the fourth fastening member. A method of abrading a workpiece using the repositionable abrasive disc is also disclosed.

A system for replacing an abrasive sheet in a sanding machine including a working head in which it is provided a support body having an engagement surface arranged to engage with an abrasive sheet. The sanding machine also includes a handling device arranged to actuate the support body in space according to at least two degrees of freedom. The system may include a computing device to compute the spatial orientation of the support body. Furthermore, the system may include a removal station having a gripping element configured to grip the abrasive sheet in order to disengage the abrasive sheet from the support body.

A system includes: a pad removal assembly; a replacement pad reservoir; an inspection unit; and a controller. The pad removal assembly includes: a separating element arranged proximal a slot; and a guide surface opposite the separating element. The replacement pad reservoir: arranged adjacent the separating element and housing sanding pads configured to couple the sanding head; and including an aperture in alignment with the guide surface. The inspection unit includes an optical sensor defining a field of view directed toward an imaging plane. The controller configured to: access an image recorded by the optical sensor depicting an abrasive area of a sanding pad arranged on a sanding head; extract features from the image; interpret an abrasive degradation for the abrasive area in the image based on the features; and in response to the abrasive degradation exceeding a threshold degradation, triggering a tool change cycle.

A hand sander and sanding disc fixture for attaching a sanding disc to a hand sander includes a table having a top with a sander storage station and an application station thereon. The storage station has a holder capable of holding a hand sander having a sander pad on the top of the table. The application station has at least two datum pegs extending from the top of the table that are capable of passing through two corresponding datum holes in the sanding disc. The at least two datum pegs having datum surfaces configured to be received in datum notches in an outer diameter of the sander pad. The datum pegs are capable of aligning the sander pad with the sanding disc when the sander pad is pressed against an attaching side of the sanding disc.

The invention relates to a grinding installation with a grinding machine having a head plate which is driven in a rotating and/or oscillating manner and is designed for receiving and releasably holding a grinding disk and with a device for replacing a grinding disk, which is releasably fixed on the head plate, with a stop element, against which the head plate with the grinding disk can be placed in a removal position, at least one removal finger which is adjustable between a retracted position and an engaged position, in which the removal finger engages into a recess on the head plate in the removal position, and a clamping means, through which the at least one removal finger is displaceable relative to the stop element, wherein the removal finger, for the purpose of releasing the grinding disk, comes to rest against its rear side and clamps the grinding disk on the stop element. The invention furthermore describes a corresponding method for replacing a grinding disk.

A sanding device includes a rotatable structure with one or a plurality of resilient extensions that extend outward from a front face of the rotatable structure. A holding structure holds an arch of sandpaper over each resilient extension such that the sandpaper arch covers a distal end of the resilient extension.
