compared with the prior art, the workpiece eccentric hole machining tool provided by the application, wherein the axial surface of the tool mandrel 10 is provided with the half-groove structure a, the half-groove structure a extends along the axis of the tool mandrel 10, two extending ends of the half-groove structure a are respectively communicated with two axial side end surfaces of the tool mandrel 10, and the tool mandrel 10 is used for sleeving a workpiece 50 to be machined, wherein the workpiece is of a certain length and hollow. At least one of the first fixing piece 20 and the second fixing piece 30 can be detachably sleeved on the shaft end of the tool mandrel 10, and the workpiece 50 to be processed can be sleeved on the tool mandrel 10 through the detachably sleeved fixing pieces. At least one of the first fixing member 20 and the second fixing member 30 is provided with a through hole structure b which is coaxial with and communicates with the half groove structure a.
After the workpiece 50 to be machined is sleeved on the tooling mandrel 10 and is limited in position, the inner wall of the workpiece 50 to be machined is opposite to the half-groove structure a. During processing, a processor stretches into the processing tool through the through hole structure b, and the processing tool can stretch into the half groove structure a because the through hole structure b and the half groove structure a are coaxial and communicated. The half groove structure a is arranged on the tooling mandrel 10, and the position of the half groove structure a relative to the central axis of the tooling mandrel 10 is determined, so that the position of the eccentric hole c to be machined on the workpiece 50 to be machined relative to the central axis of the tooling mandrel 10 can be determined in an auxiliary manner by means of the half groove structure a, and a processor can arrange the eccentric hole c to be machined relative to the half groove structure a on the inner wall of the workpiece 50 to be machined along the axial direction of the tooling mandrel 10 by means of the support of the tooling mandrel 10, so that the machining of the eccentric hole can be completed more conveniently and accurately.

Therefore, since the first fixing piece 20 is detachably sleeved at one shaft end of the tooling mandrel 10, the first fixing piece 20 is disassembled and installed, so that the workpiece 50 to be processed can be sleeved and detached from the tooling mandrel 10, and one shaft side end surface of the workpiece 50 to be processed is abutted by the position of the radial dimension difference between the second fixing piece 30 and the tooling mandrel 10, so that the workpiece 50 to be processed is limited on the tooling mandrel 10.

In a preferred embodiment, the first fixing member 20 and the connecting shaft 40 are fitted and detachably coupled by means of internal and external threads.
In one embodiment, the first fixing member 20 includes a first fixing ring portion 201 and a second fixing ring portion 202 coaxially and integrally connected to the first fixing ring portion 201, where the first fixing ring portion 201 is disposed adjacent to the tool mandrel 10, and the second fixing ring portion 202 is disposed on a side of the first fixing ring portion 201 facing away from the tool mandrel 10; the radial dimension of the first fixed ring portion 201 is smaller than the radial dimension of the second fixed ring portion 202, the circumferential surface of the first fixed ring portion 201 is provided for supporting a part of the inner wall of the workpiece 50 to be processed, and the position of the radial dimension difference between the first fixed ring portion 201 and the second fixed ring portion 202 is provided for abutting against a part of the shaft side end surface of the workpiece 50 to be processed.
In this embodiment, the first fixing member 20 and the workpiece 50 to be processed are mutually matched through a stepped structure, so as to further improve the limit stability of the first fixing member 20 to the workpiece 50 to be processed.
In other embodiments, the first fixing member 20 may be a ring structure with uniform radial dimensions, and may limit the workpiece 50 to be machined by being close to one end surface of the tooling mandrel 10.
In one embodiment, the aperture size of the through hole structure b is greater than or equal to the groove diameter size of the half groove structure a. Preferably, the aperture size of the through hole structure b is equal to the groove diameter size of the half groove structure a, so that a processor can grasp the size of the eccentric hole c to be processed according to the size of the through hole structure b.
Of course, when the aperture size of the through hole structure b is larger than the groove diameter size of the half groove structure a, the through hole structure b can facilitate the insertion of the machining tool, and the machining of the eccentric hole can be completed according to the contour line of the half groove structure a and the contour line to be machined at the mark position on the axial side end surface of the workpiece 50 to be machined.
In an embodiment, the profile shape of the through hole structure b is adapted to the profile shape of the half-groove structure a; and, along the axis direction of frock dabber 10, the contour line of through-hole structure b is parallel and level with the contour line of half groove structure a.

In other embodiments, the profile shape of the via structure b may not be adapted to the profile shape of the half-groove structure a, for example, the via structure b may be a square hole structure and the cross section of the half-groove structure a may be a semicircle.
In other embodiments, the cross section of the half-groove structure a may be U-shaped, oval or other shapes, that is, the processing tool provided in the embodiments of the present application may be suitable for processing eccentric holes with cross sections having various shapes, rather than merely suitable for processing eccentric holes with semicircular cross sections as shown in fig. 2.
