Abstract
The utility model discloses a square workpiece positioning clamp for a lathe. The positioning clamp comprises a cylindrical shank and a synchronous clamping mechanism, wherein the synchronous clamping mechanism comprises a limiting rod, a screw rod, a check ring, a left clamping block and a right clamping block. The positioning clamp is characterized in that: workpiece clamping parts of the left clamping block and the right clamping block are provided with two rectangular positioning blocks respectively and two rectangular grooves matched with the two rectangular positioning blocks; two springs are arranged on two sides of the lower end face of each rectangular positioning block; one end of each spring is fixed on the lower end face of each rectangular positioning block, and the other end of each spring is fixed at the bottom of each rectangular groove; and two semicircular bosses are arranged in the middles of the lower parts of the rectangular positioning blocks of the left clamping block and the right clamping block. When a workpiece is clamped, and the rectangular positioning blocks of the left clamping block and the right clamping block are pressed against each other, the two semicircular bosses form a circular positioning boss. The rectangular positioning blocks are used for positioning the bottom plane of the workpiece; and the circular positioning boss is used for positioning the center of the workpiece. The square workpiece positioning clamp has a simple structure, and can position the square workpiece accurately; a four-claw clamping disk and a flower disk are not required to be replaced; and therefore, the labor intensity is reduced, and the work efficiency is improved.
Description
Technical field
The utility model belongs to the machining tool clamp field, especially relates to the positioning fixture of a kind of lathe with the clamping square cross.
Background technology
In lathe turning processing, often run into the clamping of square cross, chuck or the floral disc of at this moment generally using lathe come clamping, because the chuck weight of lathe is heavier, very inconvenience are installed, and have increased master worker's labour intensity, have reduced operating efficiency.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, and is practical, is easy to make, and accurate positioning need not be changed chuck and floral disc, has reduced labourer's intensity, and the lathe of increasing work efficiency is with the positioning fixture of clamping square cross.
The technical scheme of the utility model is: a kind of lathe is with the positioning fixture of clamping square cross; Comprise cylindrical handle; Synchronous clamping mechanism; Synchronous clamping mechanism is by being inserted into gag lever post in the counterbore, being inserted into screw mandrel in the gag lever post installing hole, being fixed on the back-up ring on the optical axis and constituting through being located at the left and right sides clamp that the opposite screw thread of screw mandrel two ends and rotation direction is installed on this screw mandrel respectively through the stage casing optical axis and the shaft shoulder, and the screw mandrel end face is provided with the hexagon counterbore, it is characterized in that: clamp folder workpiece position is respectively equipped with two rectangle locating pieces in the left and right sides; Clamp folder workpiece position also is provided with two respectively and joins the rectangular channel of type with the rectangle locating piece in the left and right sides; Both sides, rectangle locating piece lower surface are provided with two springs, and spring one end and rectangle locating piece lower surface are fixed, and the other end and rectangular channel bottom land are fixed; Clamp rectangle locating piece lower middle position is respectively equipped with two semicircular boss in the left and right sides; During clamping workpiece, when the rectangle locating piece of left and right sides clamp propped up mutually, two semicircular boss will synthesize the positioning boss of a circle.
A kind of lathe is characterized in that with the positioning fixture of clamping square cross: said rectangle locating piece is used for locating the baseplane of workpiece, and circular positioning boss is used for locating the center of workpiece.
Advantage and the good effect that the utlity model has are: simple in structure, practical, be easy to make, and accurate positioning need not be changed chuck and floral disc, has reduced labourer's intensity, increases work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sketch map of the internal structure of the utility model.
Among the figure:
1, cylindrical handle 2, screw mandrel 3, clamp 301, rectangle locating piece 302, boss
