Abstract
The invention discloses an automatic centering fixture, and relates to the field of machining, in particular to the automatic centering fixture. The automatic centering fixture comprises a lead screw base, and a lead screw mounted on the lead screw base, wherein the turning directions of the left and right edges of the lead screw are opposite; the lead screw is respectively in threaded connection with a left slide block and a right slide block; V-shaped blocks are respectively arranged on the left slide block and the right slide block, and are respectively a left V-shaped block and a right V-shaped block; openings of the left V-shaped block and the right V-shaped block are opposite; and one end of the lead screw is connected with a hydraulic motor. The automatic centering fixture can automatic center, and has the advantages of simple structure, convenience for operation and wide application range; and in large-batch production, the automatic centering fixture can quick clamp workpieces, is accurate and reliable in actions, is high in production efficiency, and can automatically clamp.
Description
Technical field
The present invention relates to field of machining, be specifically related to automatically centering fixture.
Background technology
In large batch of gas thread processing, although clamping pipe is simple, but the large and duplication of labour of batch, needs a large amount of set-up times, and then adds the manufacturing cost of single-piece, also part centralizer is had at present, but inapplicable on numerical control multitool pepe threading machine, numerical control multitool pepe threading machine is the pepe threading machine that a kind of automaticity is very high, not only requiring for fixture can self-centering, and energy Automatic-clamping, general centralizer cannot meet the demands.
Summary of the invention
In order to solve the problem, the invention provides one can be self centering, and structure is simple, easy to operate, and applied widely, in production in enormous quantities, can quick-clamping workpiece, and accurately and reliably, production efficiency is high in action, and can self-holding automatically centering fixture.
Automatically centering fixture of the present invention, comprise leading screw seat and be arranged on the leading screw on leading screw seat, the rotation direction of described leading screw the right and left is contrary, leading screw has been threaded respectively left slider and right slide block, described left and right slide block is provided with V-block, be respectively left V-block and right V-block, in opposite directions, described leading screw one end is connected with hydraulic motor described left and right V-block opening.
Preferably, automatically centering fixture, also comprise the adjusting device being arranged on leading screw two ends, described adjusting device comprises and is arranged on leading screw polished rod place, and the clutch shaft bearing be connected with leading screw seat, the step surface of described clutch shaft bearing one side and leading screw offsets, another side and spacer one end face be socketed on leading screw offset, an installation pad is socketed with outside described spacer, the side of described installation pad is connected with leading screw seat, opposite side is provided with the second bearing, described second bearing holder (housing, cover) is connected on spacer, and arranged outside has bearing (ball) cover, described spacer is also provided with an adjusting nut.
