Abstract
A tension fixture for machining disc-type workpieces comprises a base and a universal mandrel. A threaded rod is fixedly connected on the base. A through hole is formed in the universal mandrel along the axial direction. The universal mandrel is sleeved on the threaded rod through the through hole and is fixedly connected with the upper end face of the base. The universal mandrel is provided with a step, and a plurality of tension plates are arranged on the step along the radial direction, are evenly distributed on the step of the universal mandrel and are symmetric along the threaded rod. A pressing plate is arranged above the universal mandrel. The pressing plate is sleeved on the threaded rod and tightly presses the tension plates through a nut. According to the tension fixture, just the tension plates need to be replaced and then different specifications of workpieces can be fixed. The tension fixture for machining the disc-type workpieces is high in machining efficiency. The centers of the workpieces remain constant relative to the threaded rod. The positioning accuracy of the workpieces can not be affected due to wear of the tension fixture.
Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of tensioning clamper of disc-like workpiece processing.
Background technology
PL700 numerical control drilling-milling machining center adopts hard-core axle class fixture to locate when processing regular circle disc type work, by the pressing plate workpiece pressing, drives workpiece rotating.Adopt this kind locate mode, when each processing work is changed fixture, all need to proofread and correct the axle center, consuming time longer, make working (machining) efficiency low, simultaneously, the fixture axle coordinates with locating hole, there is the gap between the two, can produces eccentric error in the axle operation process, affect machining accuracy.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of tensioning clamper of disc-like workpiece processing is provided, only needs to change the fixedly workpiece of different size of tensioner dish, working (machining) efficiency is high, workpiece centre is constant all the time with respect to screw rod, and does not affect positioning accuracy because of clamp wear.
The technical solution of the utility model is: a kind of tensioning clamper of disc-like workpiece processing, comprise base, be fixedly connected with a screw rod on described base, also comprise general axle, general axle is provided with through hole vertically, general axle is enclosed within on screw rod and with the upper surface of base by through hole and is fixedly connected with, described general axle is provided with step, radially be provided with several tensioner dishes on step, described several tensioner dishes are evenly distributed on the step in general axle center and are symmetrical along screw rod, general axle top is provided with pressing plate, and pressing plate is enclosed within on screw rod and compresses the tensioner dish by nut.
Described general axle is bolted to connection the upper surface at base.
Described tensioner dish is butterfly spring tensioner dish.
adopt technique scheme: be fixedly connected with a screw rod on base, also comprise general axle, general axle is provided with through hole vertically, general axle is enclosed within on screw rod and with the upper surface of base by through hole and is fixedly connected with, described general axle is provided with step, radially be provided with several tensioner dishes on step, described several tensioner dishes are evenly distributed on the step in general axle center and are symmetrical along screw rod, general axle top is provided with pressing plate, pressing plate is enclosed within on screw rod and compresses the tensioner dish by nut, the disc-like workpiece is placed on step and is circumferentially located by the tensioner dish, tensioner effect by the tensioner dish, workpiece auto-alignment screw rod, reduced eccentric error.
Be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
In accompanying drawing, 1 is base, and 2 is general axle, and 21 is step, and 3 is pressing plate, and 4 is screw rod, and 5 is nut, and 6 is the tensioner dish, and 7 is workpiece.
The specific embodiment
Referring to Fig. 1, a kind of tensioning clamper of disc-like workpiece processing, comprise base 1, be fixedly connected with a screw rod 4 on described base 1, also comprise general axle 2, general axle 2 is provided with through hole vertically, and general axle 2 is enclosed within on screw rod 4 and with the upper surface of base 1 by through hole and is fixedly connected with, the present embodiment, general axle 2 is bolted to connection the upper surface at base 1.Described general axle 2 is provided with step 21, radially is provided with several tensioner dishes 6 on step 21, the present embodiment, and the quantity of tensioner dish 6 is two, tensioner dish 6 is evenly distributed on the step 21 in general axle center 2 and along screw rod 4 symmetries.General axle 2 tops are provided with pressing plate 3, and pressing plate 3 is enclosed within on screw rod 4 and compresses tensioner dish 6 by nut 5, and the present embodiment, tensioner dish 6 are butterfly spring tensioner dish.
During use, workpiece 7 is placed on step 21, tensioner dish 6 radially is placed on step 21, control pressing plate 3 by rotating nut 5 and move down along screw rod 4, pressing plate 3 compresses tensioner dish 6, elastic deformation occurs in tensioner dish 6, and tensioner dish 6 radially extends the circumferential fixation workpiece 7 of tensioner, because tensioner dish 6 is symmetrical along screw rod 4, the center of workpiece 7 is with automatic aligning screw rod 4, base 1 rotarily drives general axle 2 rotations, and general axle 2 drives workpiece 7 rotations, realizes the processing purpose.
The utility model is simple in structure, and is easy to operate, only needs to change the fixedly workpiece of different size of tensioner dish, and working (machining) efficiency is high, and workpiece centre is constant all the time with respect to screw rod, and does not affect positioning accuracy because of clamp wear.
