Specifically, the product includes the base, vertically locates the cylinder on the base.
Specifically, two sides of the knife edge are communicated to the outside of the nesting knife, and a notch which is cut downwards along the arc shape of one side of the knife edge is formed in the bottom of the nesting knife.
The adjusting assembly further comprises a fixing nut which is arranged at the bottom of the cylinder and matched with the taper locking nut to be locked on the thread part, one end of the taper locking nut corresponds to the taper ring structure, the other end of the taper locking nut corresponds to the thread part, and the taper locking nut and the fixing nut are attached and interlocked.
Specifically, when the threaded part is locked at the highest position of the taper lock nut positioned at the bottom of the column body, the taper lock nut shrinks the tapered ring to the minimum deformation space, and the knife edge is narrowed; when the thread part is locked at the lowest position of the taper lock nut positioned at the bottom of the column body, the taper lock nut expands the maximum deformation space of the taper ring, and the knife edge is loosened.
Specifically, the knife edge and the cylinder of the product are correspondingly cut.
Compared with the prior art, the utility model discloses jacking sword adjusting device's beneficial effect mainly reflects:
through tapering lock nut cooperation tapering lock cover structure, quick fine setting edge of a knife size is applicable to the cylinder product of different tolerances, and process time shortens, and the machining precision is higher, prolongs the life of jacking sword.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention.
Example (b):
referring to fig. 1 to 3, the present embodiment is a trepanning knife adjustment device, which includes a trepanning knife 3, a taper locking sleeve 4 sleeved on the trepanning knife 3, and an adjustment assembly disposed on the taper locking sleeve 4 and used for adjusting a knife hole in the trepanning knife.
The product includes base 1, vertically locates cylinder 2 on the base 1, and the top of cylinder 2 is the toper structure.
The jacking knife 3 is of a cylindrical structure, a knife edge 31 corresponding to the cylinder 2 is arranged at the bottom of the jacking knife 3, two sides of the knife edge 31 are communicated to the outside of the jacking knife 3, and a notch 32 which is cut downwards along the arc shape of one side of the knife edge 31 is arranged at the bottom of the jacking knife 3.
The taper locking sleeve 4 comprises a hollow cylinder 41, tapered rings 42 arranged at two ends of the cylinder 41 and a threaded part 43 arranged at the joint of the cylinder 41 and the tapered rings 42; the conical ring 42 is in interference insertion fit with the trepanning cutter 3, and the bottom of the trepanning cutter 3 is inserted into the column 41 and is exposed out of the conical ring 42 at the bottom end.
The adjusting assembly comprises a taper lock nut 5 which is sleeved on the periphery of the tapered ring 42 and locked on the thread part 43, and a stop nut 51 which is arranged at the bottom of the column 41 and is matched with the taper lock nut 5 and locked on the thread part 43. The taper lock nut 5 has one end corresponding to the tapered ring 42 and the other end corresponding to the threaded portion 43. The taper lock nut 5 is locked to the position on the thread part 43 to adjust the inner diameter size of the knife edge 31, and the taper lock nut 5 and the retaining nut 51 are arranged in an attaching and interlocking mode.
When the highest position of the taper lock nut 5 at the bottom of the column 41 is locked with the thread part 43, the taper lock nut 5 contracts the taper ring 42 to the minimum deformation space, the knife edge is narrowed, and the taper lock nut 5 and the retaining nut 51 are interlocked and fixed; when the lowest thread part 43 of the taper lock nut 5 located at the bottom of the cylinder 41 is locked, the taper lock nut 5 expands the maximum deformation space of the taper ring 42, and the knife edge is loosened. The dimension of the knife edge 31 is adjusted by adjusting the height of the taper lock nut 5 on the threaded part 43.
When the adjusting assembly is applied to the embodiment, the taper lock nut 5 in the adjusting assembly is locked to the threaded portion 43 on the cylinder 41, the size of the knife edge 31 is adjusted, the trepanning knife 3 is installed on a machine table (not shown in the figure), a product can be processed in a butt joint mode, and the knife edge 31 cuts the cylinder 2 for operation.
In the embodiment, the taper locking nut 5 is matched with the taper locking sleeve 4 structure, the size of the knife edge 31 is quickly finely adjusted, the device is suitable for the cylindrical 2 products with different tolerances, the processing time is shortened, the processing precision is higher, and the service life of the trepanning knife is prolonged.
