Zero-point clamping device for positionally accurate clamping of a first component with a clamping plate on a second component with a receiving bolt , wherein the receiving bolt can be introduced into a receiving opening in the clamping plate along a longitudinal direction (L) and can be clamped in a locally fixed manner in the receiving opening by means of a clamping mechanism comprising a clamping bolt , wherein the receiving opening has along its longitudinal direction (L) a cylindrically shaped first and a cylindrically shaped second opening section (I, II) and the receiving bolt having a cylindrically or conically shaped first and second bolt section can be brought into these opening sections (I, II) from an insertion position into a storage position in the direction of the longitudinal direction (L), wherein the first bolt section can be enclosed at least partially in a form-locking manner by the first opening section (I) and/or by the second bolt section can be enclosed at least partially in a form-locking manner by the second opening section (II), and the receiving bolt can be brought, without lateral movement, from the insertion position into a bearing position in the direction of the longitudinal direction (L) of the receiving opening , characterized in that the first bolt section with a first receiving bolt diameter , the second bolt section with a second receiving bolt diameter , the first opening section (I) with an insertion hole diameter (K) and the second opening section (II) with a core hole diameter (k) are each shaped cylindrically, wherein both receiving bolt diameters are of the same size, wherein the insertion hole diameter (K) is larger than the core hole diameter (k) and wherein both receiving bolt diameters are of the same size as the core hole diameter (k). wherein the receiving opening has along its longitudinal direction (L) a cylindrically shaped first and a cylindrically shaped second opening section (I, II) and the receiving bolt having a cylindrically or conically shaped first and second bolt section can be brought into these opening sections (I, II) from an insertion position into a storage position in the direction of the longitudinal direction (L), wherein the first bolt section can be enclosed at least partially in a form-locking manner by the first opening section (I) and/or by the second bolt section can be enclosed at least partially in a form-locking manner by the second opening section (II), and the receiving bolt can be brought, without lateral movement, from the insertion position into a bearing position in the direction of the longitudinal direction (L) of the receiving opening , characterized in that the first bolt section with a first receiving bolt diameter , the second bolt section with a second receiving bolt diameter , the first opening section (I) with an insertion hole diameter (K) and the second opening section (II) with a core hole diameter (k) are each shaped cylindrically, wherein both receiving bolt diameters are of the same size, wherein the insertion hole diameter (K) is larger than the core hole diameter (k) and wherein both receiving bolt diameters are of the same size as the core hole diameter (k). <EOS>
