The technical scheme is further improved as follows: the pressing device comprises a pressing screw rod and a pressing plate, the pressing plate is pressed on the pressing screw rod through an adjusting screw, two sides of the pressing plate are fixed on the clamp body through screws, and the front end of the pressing screw rod corresponds to the part processing fixing position.
The technical scheme is further improved: and a nut is arranged at the part processing fixing position.
Has the advantages that:
use a dysmorphism tailstock eccentric orfice turning anchor clamps, when carrying out the work piece clamping, positioning accuracy is high, the clamping is simple, convenient operation, locking is reliable, machining efficiency is high, the uniformity of the part after the processing is good. Meanwhile, aiming at the eccentric parts of the special-shaped tailstock which are symmetrical left and right, the clamp considers the processing universality and can carry out flexible processing on the same clamp.
The utility model provides a pair of dysmorphism tailstock eccentric orfice turning anchor clamps, the anchor clamps body is a disc, and the direct clamping of disc is on the three-jaw chuck of lathe, and dysmorphism tailstock eccentric part clamping is fixed a position and clamping on the anchor clamps body through a hole, one side, and in addition two auxiliary stay carry out the clamping. The clamping and positioning adopt the processed hole and the processed surface in the front as the positioning reference, thereby solving the problem of poor processing precision caused by adopting the blank surface as the positioning reference. The special-shaped tailstock eccentric hole turning clamp is adopted, so that the positioning precision is high, the clamping is convenient, the clamping is reliable, the machining efficiency is high, and the dimensional precision and the consistency of machined parts are good.

In the figure: the clamp comprises a clamp body 1, a positioning mandrel 2, a pressing plate 3, a screwing screw rod 4, a nut 5, a support 6, an adjusting screw rod 7, a pressing screw rod 8, an adjusting screw 9, a pressing plate 10 and a screw 11.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to the attached drawings 1-9, the eccentric hole turning clamp for the special-shaped tailstock comprises a clamp body 1, wherein the top of the clamp body 1 is a plane, the part below the plane is in a disc shape, a positioning mandrel 2 is arranged on the plane of the top of the clamp body 1, the central position of the end surface of the disc-shaped part of the clamp body 1 is a part processing fixing position, adjusting screws 7 and support columns 6 are symmetrically arranged on two sides of the part processing fixing position, and a pressing device is arranged below the part processing fixing position; a pressing plate 3 and a tightening screw rod 4 which are matched with each other to be pressed and positioned are arranged on the positioning mandrel 2; the pressing device comprises a pressing screw rod 8 and a pressing plate 10, the pressing plate 10 is pressed on the pressing screw rod 8 through an adjusting screw 9, two sides of the pressing plate 10 are fixed on the clamp body 1 through screws 11, and the front end of the pressing screw rod 8 corresponds to a part processing fixing position; and a nut 5 is arranged at the part processing fixing position.
In the embodiment, in the clamping process, a hole of a processed part is sleeved on the positioning core shaft 2 shown in the attached drawing 5, and the part is compressed by tightening the screw rod 4 and the nut 5 and compressing the pressure plate 3; then screwing the screw rod 8 into a threaded hole of the part, and tightly pressing the screw rod 8 by the adjusting screw 9, so that the back of the part is close to the large end face of the fixture body 1; finally, adjusting screw rods 7 arranged on the pillars 6 at the left side and the right side are adjusted, so that the screw rods 7 are tightly attached to the blank surface at the outer side of the small hole of the part, and the auxiliary positioning is completed.
