Mounting unit for a tool depositing device

A storage unit for a tool depositing device having an assembly plate, the storage unit comprising:

• a coupling carrier including a coupling element, wherein the coupling carrier comprises at least one recess;
• a holding device connectable to the assembly plate of the tool depositing device, the holding device comprising:
• two guide rails, between which the coupling carrier is inserted, wherein each of the guide rails includes at least one protuberance;
• wherein the at least one protuberance of the guide rails is engaged in the at least one recess of the coupling carrier, respectively, to form a positive-fit engagement between the holding device and the coupling carrier;
• and
• an intermediate space provided between the holding device and the coupling carrier to permit compensation movements between the coupling carrier and the holding device, the intermediate space including at least one gap between non-bearing surfaces of the at least one protuberance and the at least one recess;
• wherein the at least one recess and the at least one protuberance are arranged on engaging sides of the coupling carrier and the guide rails;
• bores provided in the guide rails and in the coupling carrier, the bores configured to be aligned to one another in a flush manner such that they have a common center axis perpendicular to the course of the guiderails by displacing the coupling carrier along the two guide rails;
• and
• a securing pin pushed into the bores that are aligned in a flush manner in order to secure the coupling carrier in the holding device.
