The present invention provides a quick-change type tool holder structure with high positioning accuracy, comprising a cutting insert, a tool support rod and a tool holder connected in turn, said tool support rod and tool holder having a through hole in the centre of the cutting insert and the tool holder, a Threaded Insert Fitting Holes is provided in the through hole, said Threaded Insert Fitting Holes are connected to the cutting insert and the tool holder respectively at each end of the screw, the Limit Fitting Surface are provided as a cutting hole on the internal cylinder surface of the cutting hole of the cutting support rod close to the cutting insert at the end of the cutting hole, and the said Limit Fitting Surface is connected in a matching manner with the cutting insert. The present invention has the following beneficial effect: by connecting the Limit Fitting Surface with the tool holder through the Threaded fasteners, it avoids the opening of threads on the tool support rod, and then the tool support rod can be used with the use of cemented carbide material, combined with the structure of the mating holes, which solves the technical problem of the existing tool holders with an overly complex structure, and obtains a simple structure and a high positioning accuracy of the structure of the tool support rod.
A quick-change type tool holder structure with high positioning accuracy, characterised in that it comprises a cutting insert, the support support rods and the tool holder connected in sequence, said the support rod and the tool holder having a through hole in the centre of the tool holder, said through hole being provided with a Threaded fasteners, said Threaded fasteners being connected to the cutting insert and the tool holder at both ends respectively, said through hole of the support rod being set as a Limit Fitting Surface in the inner cylindrical surface of the support rod near the end of the cutting insert, and said Limit Fitting Surface fitting holes in the cutting insert.
