Abstract
The utility model relates to a fixture for milling of a square hole on an end face of a spindle, which comprises a base. A hollow cylinder is arranged on the base, the outer surface of the hollow cylinder is provided with an upper threaded hole and a lower threaded hole, screw rods capable of extending into an inner cavity of the hollow cylinder are connected into the corresponding threaded holes, and a through hole communicated with the inner cavity of the hollow cylinder is arranged at a position of the base under the hollow cylinder. Therefore, when the spindle is clamped in the hollow cylinder, tools such as a jack, an ejector pin or the like can penetrate through the through hole to jack the spindle out.
Description
Technical field
The utility model relates to a kind of frock, particularly a kind of milling spindle end face square hole frock.
Background technology
In the processing of square hole axle; Need go out the square hole perpendicular to end face at the face milling of axle, traditional method is that axle is placed in the vertical cylindrical hole, and this cylindrical hole just can chimeric axle; So the vertical axis of cylindrical hole is basic and the dead in line of axle; Realize the perpendicular positioning of its axis,, can't guarantee that axis is a vertical direction owing to have certain clearance all the time between cylindrical hole and the axle.Occur a kind of milling spindle end face square hole frock of accurate positioning at present, comprised base, on base, be provided with hollow cylinder; The outer surface of this hollow cylinder has two screwed holes that are provided with up and down; Be connected with the screw rod that can stretch into the hollow cylinder intracoelomic cavity in the screwed hole, utilize two screw rods locking, make a bus of axle be close to the inwall of hollow cylinder; Realize the perpendicular positioning of axis, accurate positioning.Its shortcoming is: axle is prone to be stuck in the cylindrical cavity after milling finishes.
Summary of the invention
The technical problem that the utility model will solve provides a kind of milling spindle end face square hole frock that makes things convenient for discharging.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of milling spindle end face square hole frock; Comprise base, on base, be provided with a hollow cylinder, the outer surface of this hollow cylinder has two screwed holes that are provided with up and down; Be connected with the screw rod that can stretch into the hollow cylinder intracoelomic cavity in the screwed hole, its innovative point is: have on the said base that is positioned under the hollow cylinder one with the through hole of hollow cylinder intracoelomic cavity conducting.
The advantage of the utility model is: on the base that is positioned under the hollow cylinder, have one with the through hole of hollow cylinder intracoelomic cavity conducting, in the time of in axle is stuck in hollow cylinder, can passes through hole by instruments such as jack or push rods axle is ejected.
Description of drawings
Accompanying drawing 1 is the utility model milling spindle end face square hole tool structure sketch map;
The specific embodiment
Like accompanying drawing 1, shown in 2, the utility model comprises base 1, hollow cylinder 2, screwed hole 3, screw rod 4, through hole 5, axle 6.
Being welded with axis on the above-mentioned base 1 is the hollow cylinder 2 of vertical direction; The outer surface of this hollow cylinder 2 has two screwed holes 3; These two screwed holes 3 are positioned on the same bus of hollow cylinder 2 outer surfaces, are connected with the screw rod 4 that can stretch into hollow cylinder 2 inner chambers in the screwed hole 3.
During milling, axle 6 is placed in the hollow cylinder 2,, make a bus of axle 6 be close to the inwall of hollow cylinder 2, realize the perpendicular positioning of axle 6 axis through two screw rods 4 lockings; In axle 6 is stuck in hollow cylinder 2; On the base 1 that is positioned under the hollow cylinder 2, have one with the through hole 5 of hollow cylinder 2 inner chamber conductings; In the time of in axle 6 is stuck in hollow cylinder 2, can passes through hole 5 through ejector beam or other instruments axle 6 is ejected, avoid axle 6 to take out.
