Abstract
The invention belongs to the technical field of lathe fixtures, and particularly relates to an elastic disc turning fixture. The elastic disc turning fixture comprises a pull rod, a fixture body and an elastic disc, wherein the pull rod is arranged at the axis of the fixture body; the elastic disc is umbrella-shaped, sleeves the front end of the pull rod, and is fixed on the pull rod through a nut; the axis of the elastic disc adopts a shaft sleeve structure matched with the pull rod; a conical structure connected with a tightening hydraulic cylinder on the tail part of a lath spindle is arranged at the back end of the pull rod; an arc-shaped elastic thin plate tightly adhered to the fixture body is arranged between the elastic disc and the fixture body; an auxiliary spring is arranged between the elastic thin plate and the fixture body. The elastic disc turning fixture is simple in structure and convenient and labor-saving to operate.
Description
Technical field
The invention belongs to turning attachment technical field, be specifically related to resilient disc turning clamp.
Background technology
Lathe does not generally have special fixture to carry out clamping to it when the cylindrical of machining large ring disk-shaped part and end face, and existing to carry out the fixture general structure of clamping to large-scale ring disk-shaped part complicated, and operation inconvenience is convenient not.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides resilient disc turning clamp, and this clamp structure is simple, easy to operate and laborsaving.
The technical solution adopted in the present invention is as follows: resilient disc turning clamp, comprise pull bar, clamp body and resilient disc, described pull bar is located at the axle center place of clamp body, resilient disc is that umbrella sleeve is located at pull bar front end and is fixed on pull bar with nut, resilient disc axle center is the axle sleeve structure coordinated with pull bar, back end of tie rod is the pyramidal structure be connected with the tension hydraulic cylinder of machine tool chief axis afterbody, also be provided with the arc elastic thin plate being close to clamp body between resilient disc and clamp body, between elastic sheet and clamp body, be also provided with secondary spring.
Spacer is provided with between described nut and resilient disc.
Described clamp body relative position is provided with the axis hole holding secondary spring.
Described clamp body is provided with the bolt hole be connected with machine tool chief axis dish.
The invention has the beneficial effects as follows: adopt such scheme, clamp body is fixed on lathe main reel, back end of tie rod is connected with the tension hydraulic cylinder of main shaft tail, workpiece is enclosed within workpiece on pull bar, workpiece rear end puts umbrella shape resilient disc and again with nut pre-pressing, spacer between nut and resilient disc can prevent resilient disc from wearing and tearing, hydraulic control cylinder moves after pulling pull bar and makes the outside spreading of umbrella shape resilient disc and workpiece fit and compress, arc elastic thin plate between workpiece and clamp body is also out of shape thereupon, secondary spring plays the effect of buffering and auxiliary clamp power, workpiece two sides all compresses with flexible member, compress firmly, and it is easy and simple to handle laborsaving, clamp structure is simply ingenious, after hydraulic cylinder resets, resilient disc and elastic sheet all reset, workpiece is unclamped.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is schematic cross-section of the present invention.
Wherein: 1 is clamp body, 2 is resilient disc, and 3 is pull bar, and 4 is nut, and 4.1 is spacer, and 5 is elastic sheet, and 5.1 is secondary spring.
Detailed description of the invention
Resilient disc turning clamp as shown in Figure 1, comprise pull bar 3, clamp body 1 and resilient disc 2, pull bar 3 is located at the axle center of clamp body 1, pull bar 3 rear end is the pyramidal structure be connected with the tension hydraulic cylinder of machine tool chief axis afterbody, resilient disc 2 is umbrella shape, be set in pull bar 3 front end and fix with nut 4, separate to protect resilient disc 3 from wearing and tearing with spacer 4.1 between nut 4 and resilient disc 2, and resilient disc 2 axle center place is the axle sleeve structure coordinated with pull bar 3, for being close to the arc elastic thin plate 5 of clamp body 1 between resilient disc 2 and clamp body 1, it is secondary spring 5.1 between elastic sheet 5 and clamp body, clamp body 1 relative position is provided with the axis hole holding secondary spring 5.1, secondary spring 5.1 cushions and provides auxiliary clamp, hydraulic-driven tension handled easily, more laborsaving.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
