Abstract
The invention relates to a no-stopping cutting clamp, which relates to the field of a mechanical auxiliary device, in particular to a non-stopping cutting clamp. The no-stopping cutting clamp comprises a clamp cone which is matched with a conical hole of a turning lathe main shaft, three claw supports are arranged on the other end of the clamp cone, the front end of each claw support is respectively connected with an arch claw in a rotating manner, one end of each claw is used for clamping a workpiece, the other end of each claw is connected with an alignment centre, and the alignment centre is connected with a force regulation screw which is arranged on the matched end of the clamp cone and the turning lathe main shaft conical hole through a spring. By adopting the non-stopping cutting clamp, the workpiece can be installed and disassembled without stopping the machine, the structure is simple, convenience in disassembling is realized, time is reduced, the efficiency is high, the labor intensity of workers can be alleviated, and the mass production can be realized.
Description
Technical field
The present invention relates to assist field, be specifically related to not stop cutting jig.
Background technology
In cutting process, axial workpiece must remain correct location and clamping in jig, the crudy of guarantee part.At present, in Machining of Shaft-type Parts, have a lot of clamping method, all have that some is not enough, although if any method can ensure clamping force and precision, clamping speed and efficiency can not be ensured; Although some methods can ensure clamping speed and efficiency, but its clamping precision can not be ensured.If use the cutting jig that do not stop, just can make up above-mentioned
Deficiency, can reach save time, convenient, can crudy be ensured again.
Current installation way is: (1) uses independent chuck clamping, due to 4 claw self-movements separately of independent chuck, therefore must by the pivot centering of processing part during clamping workpiece, and just can turning after overlapping with lathe spindle pivot.Although independent chuck clamping force is comparatively large, centering is more time-consuming, so be applicable to the large-scale or workpiece in irregular shape of clamping.Independent chuck can dress up positive pawl or anti-pawl 2 kinds of forms, and anti-pawl is used for the larger workpiece of chucking diameter, if but carry out turning shaft parts with it, alignment time is long, and operating efficiency is not high yet; (2) self-centering chuck clamping, 3 claws of self-centering chuck are synchronized with the movement, and energy self-centering, is applicable to the medium and small workpiece of clamping external form rule, does not generally need centering after clamping workpiece.But time turning is compared with longaxones parts, be just difficult to ensure its rigidity and form and position tolerance, so be still not too applicable to turning shaft parts with self-centering chuck; (3) two top clampings, for longer, just or have to pass through the workpiece that multiple clamping can process, or operation is more, also wants the workpiece of milling and grinding after turning, in order to ensure clamping precision during each clamping, available two top clampings.Two top clampings do not need centering, and clamping precision is high, apply very extensive.But its mounting or dismounting workpiece is cumbersome, and with two top clamping workpieces, must get out centre bore at workpiece end face.Also compare lose time so be used for turning shaft parts, production efficiency is difficult to ensure; (4) one folder one top clampings, one folder one top clamping (clamp by one end chuck, the other end withstands with top) axial workpiece, this clamping method good rigidly, larger axial cutting force can be born, but clamping is cumbersome, and during for multiple clamping or finish turning, workpiece form and position tolerance be difficult to ensure and more time-consuming.
Summary of the invention
In order to solve the problem, the invention provides one and not stopping and just can install and remove workpiece, structure is simple, easy accessibility, saves time, efficiency is high, can alleviate labor strength, the cutting jig that do not stop of registration.
The present invention is not stopped cutting jig, comprise the fixture cone matched with lathe spindle taper hole, the described fixture cone other end is provided with three finger mountings, described each finger mountings front end is all rotatably connected to an arc claw, one end of described claw is for accommodating workpiece, the other end to be toply connected with centering, described centering top by spring be arranged on fixture cone and the lathe spindle taper hole force adjustment screw held that matches and be connected.
Preferably, top one end for axle of feeling relieved is provided with conical boss, and the boss face of conical boss is provided with a cone, the boss face of described conical boss is identical with the bottom surface diameter of cone, and is mutually permanently connected.
Preferably, finger mountings is provided with a stop screw, described stop screw is positioned at the bending outside of arc claw.
The present invention is not stopped just can install and remove workpiece, and structure is simple, easy accessibility, saves time, efficiency is high, can alleviate labor strength, can realize batch production.
Accompanying drawing explanation
Fig. 1 is not for stopping cutting jig structural representation.
Reference numeral: 1-force adjustment screw, 2-fixture cone, 3-spring, 4-stop screw, 5-centering is top, 6-finger mountings, 7-claw, 8-workpiece.
Detailed description of the invention
The present invention is not stopped cutting jig, comprise the fixture cone 2 matched with lathe spindle taper hole, described fixture cone 2 other end is provided with three finger mountings 6, described each finger mountings 6 front end is all rotatably connected to an arc claw 7, one end of described claw 7 is for accommodating workpiece, the other end top 5 to be connected with centering, described centering top 5 by spring 3 be arranged on fixture cone 2 and the lathe spindle taper hole force adjustment screw 1 held that matches and be connected.Feeling relieved top 5 is that one end of axle is provided with conical boss, and the boss face of conical boss is provided with a cone, the boss face of described conical boss is identical with the bottom surface diameter of cone, and is mutually permanently connected.Finger mountings 6 is provided with a stop screw 4, described stop screw 4 is positioned at the bending outside of arc claw 7.
During use, fixture cone 2 is loaded in lathe spindle taper hole, start lathe, left hand holds workpiece 8, the centre bore of workpiece one end is first contacted with tailstock tool is top, the top handwheel of right hand shake tailstock tool march forward to, the other end technique centre bore of workpiece is first contacted with centering top 5; Decontrol left hand and continue feeding, move, three claws 7 are circled, thus is clamped by workpiece 8 after top 5 frustums of a cone of feeling relieved, the top handle of locking tailstock tool can carry out turnery processing.After processing, unclamp tailstock tool top and retreat, workpiece 8 just moves forward under the effect of spring 3 along with centering top 5, and claw 7 is unclamped automatically, and workpiece 8 can unload, and completes a fabrication cycles thus.Stop screw 4 plays a part to prevent top 5 rotations of feeling relieved.The pressure size of force adjustment screw 1 adjustable springs 3.
