The present disclosure relates to a tool holder to receive and lock a tool taper on a tool magazine, an unlocking device to unlock a tool taper that is received and is locked in a tool holder of this type, and a tool magazine for a machine tool comprising one or more tool holders of this type and an unlocking device of this type.

Tool magazine for the provision of tools for a machine tool, wherein the tool magazine has a multiplicity of receiving positions for tools. A first tool can be removed from or inserted into a first receiving position along a removal direction, and at least one further receiving position for receiving a further tool is provided.

A machining center including a machine main body, an upper section of which supports a head moving device and a head raising and lowering device, configured such that tool magazine 120 is stored inside the machine main body, and with a magazine moving device configured to move tool magazine 120 such that, during tool exchange, tool magazine 120 is advanced to protrude from a side of the machine main body, so that, from the multiple tool holders, the tool holder used for exchange is positioned inside the movement range of the main shaft by the head moving device, and wherein the entire tool magazine 120 is able to be moved beyond the movement range of the tool magazine by the magazine moving device to a position outside of the machine main body and detached from the machine main body.

To provide an abnormality determination apparatus, a computer readable medium, an abnormality determination system and an abnormality determination method which can simply detect an abnormality of a temperature in a machine tool without incurring cost. An abnormality determination apparatus which determines abnormality of a temperature sensor in a plurality of machine tools, in which the plurality of machine tools is equivalent machine type, is arranged in equivalent environments, are provided with a temperature sensor at equivalent positions, the abnormality determination apparatus including: a temperature data acquisition unit which acquires temperature data outputted by the temperature sensors from each of the plurality of machine tools; a comparison unit which compares the temperature data acquired by the temperature data acquisition unit; and an abnormality determination unit which determines abnormality of the temperature sensor based on a comparison result by the comparison unit.

A conveyance chain comprises a plurality of link plates alternately coupled and conveying plural tool pots each holding a tool. The plurality of link plates include an inner link plate and an outer link plate each including a rotation stop hole that stops a rotation of the tool pot and a rotation permit hole located upstream from the rotation stop hole with respect to a conveyance direction that permits a rotation of the tool pot. The plurality of tool pots includes a first tool pot and a second tool pot, the first tool pot is inserted through a rotation stop hole of the inner link plate and a rotation permit hole of the outer link plate, and adjacent to the first tool pot, the second tool pot is inserted through a rotation permit hole of the inner link plate and a rotation stop hole of the outer link plate.

A tool machine magazine includes a base, a tool disc disposed on the base, tool sleeves disposed on a periphery of the tool disc through a bearing, a motor, a brake structure, a cam, a driver shaft, an angle sensor, and a control terminal. The motor drives the cam to operate. Each bearing orderly operates along the outline of the cam, driving the tool disc to continuously rotate without intermittence. The angle sensor is disposed on one end of the driver shaft or a rotation center of the tool disc. When the rotation angle of the tool disc matches the tool change command, the control terminal controls the brake structure to stop the motor, so as to stop the tool disc for facilitating the tool change operation.

A boring-bar arrangement includes a boring bar, a securing device, and a clamping bolt. The securing device has a reduction sleeve, which is secured in a tool chuck, which has a front end that faces away from the tool chuck and a protruding hollow section which receives the boring bar. The hollow section has a hollow-section interior, a hollow-section outer wall, and a hollow-section wall which is arranged therebetween. The hollow-section wall has a first thickness in a side region where the cutting tool protrudes from the boring bar which is less than a second thickness in a rest of the hollow-section wall. The boring bar is releasably secured as a replaceable head, via its back end, at a front end of the protruding hollow section. A front end of the clamping bolt has a male thread which sits in the female thread of the boring bar.

A loading device for a loading of an installation, in particular a multi-clamping and measuring and/or presetting station for tools and/or tool holders, and/or a machine tool, in particular includes at least one handling robot, having at least tool holders and/or tool assemblies, having a rollable undercarriage unit and having a storage unit, arranged on the rollable undercarriage unit, for a storage of the tool holders and/or of the tool assemblies,

wherein the storage unit has at least one holding device at least for an oblique-positioned holding of the tool holders and/or of the tool assemblies relative to a put-up direction of the storage unit.

A magazine comprises: a conveyer unit that has a plurality of tool pots that each hold a tool detachably and conveys the plurality of tool pots; and a magazine cover that accommodates the conveyer unit. The conveyer unit allows a tool to be manually attached to and detached from a tool pot conveyed to a predetermined position. The magazine further comprises a display unit that is provided inside the magazine cover and displays a first design.

The first design represents an arc or circumference for a diameter corresponding to a maximum diameter of a tool which can be held by the tool pot.

Provided is a tool pot overcoming a problem that dirt adhered to the tool pot is transferred to a contact face of a tool. A tool pot includes an inner-periphery holding part that holds an inner periphery of a tapered shank and prevents axial movement of a tool, an end-face holding part that prevents rotation of the tool, which is implemented by a key fitted into a keyway provided at an end surface of the tapered shank, and an outer-periphery holding part that is opposed to an outer periphery of the V-flange and prevents radial movement of tool. The inner-periphery holding part, the end-face holding part, and the outer-periphery holding part hold the tool in a state where there are clearances with respect to an outer peripheral surface of the tapered shank and an end face of the V-flange, respectively.
