Further, the deep hole tool holder further comprises: the base, slide, blade holder supporting seat and blade holder, the slide sets up the base upper end, the blade holder supporting seat is established and is located the slide rear side the base upper end, blade holder fixed mounting be in the slide upper end, and with blade holder supporting seat sliding connection.

Furthermore, a sliding groove is formed below the base and matched with a slide way of a machine tool.

Further, a tool apron slideway is arranged on the upper end surface of the tool apron supporting seat.

Furthermore, the jackscrew passes through two through holes on the upper end surface of the tool apron clamping sleeve and is in threaded connection with the tool apron clamping sleeve.

In one embodiment, under the normal working condition, one end of a workpiece is clamped and fixed through the clamping jaws of the chuck, the other end of the workpiece is clamped and fixed through the closed center frame, meanwhile, a required boring cutter or a required drilling cutter can be installed on the deep hole tool rest according to requirements, the tool bar is screwed and fixed through the jackscrew, the tool bar is prevented from rotating, the installed boring cutter or the installed drilling cutter can move transversely and longitudinally along with the sliding plate, and the processing requirements of different workpieces in different sizes are met.

Due to the adoption of the technical scheme, compared with the prior art, the cutter holder is respectively provided with the two cutter holder clamping sleeves along the axis direction of the workpiece, the problems that the cutting force is unbalanced and the deformation of the cutter bar is large and the like when a customer uses a longer boring rod or a drill rod are solved, the stability of the cutter bar is ensured, in addition, the deep hole cutter holder can move transversely and longitudinally along with the sliding plate, the position of the workpiece is not required to be manually adjusted, the processing requirements of different workpieces are met, the requirement on processing precision can be met, the labor intensity can be reduced, the rejection rate is greatly reduced, the operation is simple, the use is convenient, and good economic benefits are achieved.
