A rectangular through hole 38 is opened at one end of the second fixed block 37. The rectangular through hole 38 is adapted to the handle 401 of the turning tool. The turning tool structure 39 is arranged in the rectangular through hole 38. The handle 401 passes through the rectangular through hole 38 and extends into the turntable 171 until it contacts the fixing screw.

[0035] The turning tool structure 39 includes a tool handle 401, a gasket 42, a turning tool body 44 and a pressure rod 48. The tool handle 401 extends into the rectangular through hole 38 and is fixedly connected by screws. The tool handle 401 can be stabilized by the action of a screw and a fixing screw.

The first motor 5 and the third fixed block 7 are fixedly installed on both sides of the first mounting block 2. The first motor 5 has a housing. A first threaded rod 6 is rotatably connected between the first motor 5 and the third fixed block 7. The first motor 5 can drive the first threaded rod 6 to rotate. Each first threaded rod 6 passes through a pair of threaded holes 12 and is threadedly connected thereto. The two first motors 5 rotate synchronously. When the threaded rod rotates, the entire clamping device 8 will slide on the first slide groove 3.

[0044] In actual use, a tool installation and positioning device for special-shaped lathe processing, when a certain turning tool is needed, it is necessary to first install the bracket assembly 141 in a suitable position, and then replace the used tool to the working position, and then start the driving mechanism 151 and the first fixer 9, so that the blade and the clamped object are slightly touched, and finally cutting is performed. During use, the turning tool body 44 can be replaced by itself, and the handle 401 of the turning tool is universal, so it is convenient to use the second fixing block 37 to fix it uniformly. When replacing the handle 401 or the blade, some screws need to be removed, but under normal circumstances, the turning tool body 44 will not easily leave the handle 401 unless the turning tool body 44 must be replaced. When using the drill bit 36, if the object fixed by the first fixer 9 cannot rotate, the drill bit 36 ​​must be rotated. Similarly, if the first fixer 9 rotates, the drill bit 36 ​​can be stationary. Of course, the drill bit 36 ​​can choose to rotate in the opposite direction at a low speed at this time.
