Abstract
The utility model relates to a cantilever flexible claw with an auxiliary support and belongs to the mechanical machining field. The cantilever flexible claw comprises a claw connecting piece, a cantilever, a compaction push pedal, a compaction screw and a compression block. The rear end of the claw connecting piece is fixed to a chuck on the main shaft of a lathe. The lower part of the front end of the claw connecting piece is fixedly provided with a claw used for clamping the front end of a workpiece. The upper part of the front end of the claw connecting piece is fixed to the rear end of the cantilever. The compression screw is arranged to penetrate through a connecting long hole in the compression screw to be threadedly connected inside a threaded hole at the front end of the cantilever. In this way, the upper surface of a positioning bench at the lower end of the compaction push pedal is lower than the inclined plane of the lower part of the front end of the cantilever. The compression block is arranged between the inclined plane of the lower part of the front end of the cantilever and the to-be-clamped workpiece. According to the technical scheme of the utility model, the cantilever flexible claw has the advantages of simple structure and convenient clamping. The technical problem in the prior art that conventional flexible claws are incapable of effectively clamping large-length-diameter thin-walled conical workpieces can be solved. Meanwhile, the phenomena that workpieces to be clamped easily deform and chatter marks easily form on the surfaces of the workpieces can be avoided effectively. Therefore, a guarantee is provided to ensure the subsequent machining accuracy.
Description
Technical field
The utility model relates to the soft pawl of a kind of cantilever with supplemental support, belongs to field of machining.
Background technology
Soft pawl is that mechanical processing industry uses very general a kind of fixture, is mainly used in processing some sizes, axle, cover, tube kind part that form accuracy is higher.The clamping area of conventional softer pawl is after finish turning, and three form pairs, holding workpiece cylindrical or endoporus.In the time of the smaller cylinder-shaped thin wall part of some major diameters of processing, common soft pawl can play clamping action effectively, makes the part after clamping complete smoothly following process.But for the larger thin-walled Tapered Cup of draw ratio, example empennage barrel part as shown in Figure 1, entirety is tapered, small end has internal thread, and large end has external screw thread, holds greatly screw thread and interior profile in small end screw thread Geometrical Tolerance Principle 0.05mm, draw ratio=2.5, because the clamping face of end is less, use by force common soft pawl processing very easily to produce size distortion and the surface line that quivers, have a strong impact on outward appearance and the serviceability of product.
Utility model content
The purpose of this utility model is in order to solve conventional softer pawl when the larger thin-walled Tapered Cup of clamping draw ratio, part deformation size distortion and the surface shortcomings such as line of quivering easily occurs, and provide a kind of cantilever with supplemental support soft pawl.
The purpose of this utility model is achieved through the following technical solutions:
The soft pawl of a kind of cantilever with supplemental support of the present utility model, comprises claw connector, cantilever, compression push pedal, housing pin and compact heap;
Wherein, the front end end of cantilever is processed with screwed hole, and the front end bottom of cantilever is processed as inclined-plane, and the angle of inclination on this inclined-plane is greater than the tapering of workpiece sidewall to be held;
The center that compresses push pedal has connection slotted hole, and positioning table is extended to same lateral plates vertical direction in the two ends that compress push pedal connection slotted hole,
The upper surface of compact heap is the inclined-plane corresponding with cantilever front end lower bevel; The lower surface of compact heap is the clamping area matching with workpiece sidewall profile to be held;
Chuck on rear end and the lathe spindle of claw connector is fixed, and the front end bottom of claw connector fixedly has and the match claw of clamping area of workpiece front end profile to be held, for holding workpiece front end; The upper front end of claw connector and the rear end of cantilever are fixed, and housing pin is threaded in cantilever front end screwed hole through compressing the connection slotted hole of push pedal, make to compress the upper surface of push pedal lower end positioning table lower than the inclined-plane of cantilever front end bottom; Compact heap is placed between the inclined-plane and workpiece to be held of cantilever front end bottom.
The course of work
Clamping work pieces makes, first by the front end of the chuck control claw clamping work pieces on lathe spindle, then screw thread screws housing pin, the lower positioning table that compresses push pedal is drawn close to compact heap one side, promote the sidewall of compact heap clamping work pieces under the effect of cantilever front end lower bevel, front end and the sidewall of realizing workpiece clamp simultaneously, complete following process.
Beneficial effect
The soft pawl of cantilever of the present utility model is simple in structure, convenient mounting and clamping, the technological difficulties that conventional softer pawl cannot effectively clamp thin-walled Tapered Cup that draw ratio is larger are solved, effectively avoid the easy generation distortion of workpiece to be held and the surface line problem of quivering, for the precision of part following process provides safeguard.
