Abstract
The utility model discloses a material drawing device, which comprises clamping jaws, a cylindrical pin, a disc spring seat, a clamping jaw seat, a disc spring, a propping sleeve and a matrix. At least two clamping jaws are symmetrically locked in a T-shaped groove at the front end of the clamping jaw through an adjusting mechanism; a hook head is arranged on the inner radial side of the rear end of the clamping jaw seat; the clamping jaw seat is mounted on the matrix through the cylindrical pin and can rotate around the cylindrical pin; the disc spring seat is fastened in a groove in a symmetric center of the matrix; the disc spring is sleeved on the disc spring seat, and tightly buckled through the propping sleeve; and the end part of the propping sleeve is propped against the hook head of the clamping jaw seat under the action of spring force, so as to ensure that the clamping jaw seat rotates around the cylindrical pin together with the clamping jaws to realize blank clamping. Without adopting a piston push rod and a hydraulic or pneumatic device, the material drawing device has simple structure, occupies the little ground, produces no vibration and no noise, and is particularly suitable for automatic feed of a pipe rod material with small diameter.
Description
One, technical field
The utility model relates to a kind of lathe aid, especially is used for pulling out automatically the glassware that pulls out of material during machine tooling, realizes the automatically feed glassware that pulls out at lathe turning pipe bar specifically.
Two, background technology
In the machine part smear metal was processed, some part directly adopted the bar of standard and manages material as blank, whenever finished a parts rod material or pipe and expected to send a part length to, so circulated, and used until exhausted until bar or pipe material.That generally adopts at present has hydraulic pressure and a pneumatic tube rod feed, its common feature is: have two supports to hold up a feed pipe, feed pipe is used for holding the pipe bar, other has a piston push rod that is used for the propulsion tube bar that is placed in the feeding pore, piston push rod is under the effect of hydraulic pressure or air pressure, promote the pipe bar and move, realize the automatic feed material.This type of feed appliance: 1. complex structure; 2. floor space is bigger; 3. add and manage bar man-hour with the lathe main axis rotation because a pipe bar longer part stretches in the feeding pore, produce during rotation violent vibration and with feed pipe inwall bump, produce ear-piercing noise pollution, and vibration can have a strong impact on the crudy of part.In addition, owing to be subjected to structural limitations that diameter is difficult to realize self-feeding less than the pipe bar below the 10mm.
Three, summary of the invention
1, goal of the invention: the purpose of this utility model provide a kind of simple in structure, do not take up an area of face, friction noise and be particularly suitable for the narrow tube bar self-feeding pull out glassware.。
2, technical scheme: a kind of glassware that pulls out, it comprises claw, straight pin, the dish spring abutment, master jaw, the dish spring, top cover and matrix, described at least two claws are locked in the T type groove of master jaw front end by the governor motion symmetry, master jaw rear end radially inner side has gib head, master jaw is installed on the matrix by straight pin and can rotates around straight pin, the dish spring abutment is fastened in the groove of matrix symmetrical centre position, the dish spring is sleeved on the dish spring abutment, the top hitch is pushed down the dish spring, and on the gib head of end roof pressure at master jaw of top cover under the effect of spring force, master jaw is rotated and realization clamping blank around straight pin together with claw.
Above-mentioned governor motion comprises screw and latch segment, and the through hole that screw passes on the claw inserts in the T type groove of master jaw front end, and is locked by the latch segment in the T type groove.
Operation principle: will pull out glassware and pack on the support of machine tool dragging plate, part blank (pipe material or bar) is placed in the lathe spindle hole, and chuck clamps blank, and machine tool dragging plate will pull out glassware and move to blank end and machine tool chief axis axis almost coaxial.The distance of pulling out between glassware two claws is transferred to less than the about 2-3mm of blank diameter, machine tool dragging plate moves to blank along the blank axis, because claw can rotate around its straight pin, blank head can insert easily and pull out glassware, after the about 10-15mm of glassware is pulled out in insertion, blank is clamped under the effect of two claws and dish spring, and unclamp machine chuck this moment, and blank is in free state; Then machine tool dragging plate retreats along the blank axis, and blank is extracted a Workpiece length, and machine chuck clamps blank subsequently, machine tool dragging plate continues to retreat along the blank axis, until breaking away from blank, once pull out the material process to this for finishing, whenever machine a part later on and so circulate.
3, the beneficial effects of the utility model: because the utility model need not to adopt piston push rod and hydraulic pressure or pneumatic shuttle, the face that do not take up an area of again simple in structure; In the process, the pipe bar with pull out glassware and do not have any contact, can not produce and vibrate and noise, be particularly suitable for the self-feeding of narrow tube bar.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to structural representation.
Five, the specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1-2, the utility model mainly is made up of claw 1, screw 2, latch segment 3, straight pin 4, dish spring abutment 5, master jaw 6, dish spring 7, top cover 8, matrix 9, screw 10.Claw 1 is connected with latch segment 3 by screw 2, claw 1 is locked in the T type groove of master jaw 6, unclamps screw 2, and claw 1 can move in master jaw 6T type groove with latch segment 3, adapts to the clamping of different-diameter pipes bar.Master jaw 6 can rotate around straight pin 4, and dish spring abutment 5 is fastened in the groove of matrix 9 by screw 10.Dish spring 7 is sleeved on the dish spring abutment 5, and top cover 8 is withheld dish spring 7, the gib head of the end roof pressure master jaw 6 of top cover 8 under the effect of spring force.Master jaw 6 is rotated around straight pin 4 together with claw 1, realize the clamping blank.
