Abstract
The utility model discloses a but quick assembly disassembly's boring grab relates to the jig field, and the purpose is for solving the current slow problem of boring grab dismouting efficiency, and its technical scheme has set up dabber (2) at anchor clamps base (1) middle part, the end of dabber (2) is provided with Y -type eccentric wheel (9) base (1) and Y -type eccentric wheel (9) between set gradually bearing pad piece (3), disc spring (6), extrusion cushion (7), eccentric wheel cushion (8), bearing pad piece (3), disc spring (6), extrusion cushion (7), eccentric wheel cushion (8) cup joint on the outer face of cylinder of dabber (2), the utility model discloses the convenience is is just installed and removed to the simple structure, anchor clamps are longe -lived, with low costs, and the dismouting is efficient, and is effectual, has improved productivity ratio greatly, satisfies the needs of production.
Description
Technical field
The utility model relates to frock clamp in field of machining, particularly relates to a kind of boring grab of fast demountable.
Background technology
Drilling operation on disk-like accessory adopts line or Special drilling jig processing usually, no matter is which kind of processing, all needs to fix clamping to disk-like accessory.In known technology, the general nut that adopts is locked the disc type work after clamping, in mass drilling operating, adopts the mode of nut check to need to lock workpiece before work pieces process, unclamps nut again, there is the problem that clamping efficiency is slow after processing.
Utility model content
The purpose of this utility model overcomes above-mentioned defect, develops a kind of high efficiency boring grab realizing fast assembling-disassembling.
The utility model realizes by the following technical solutions: a kind of boring grab of fast demountable, comprise base (1), described base (1) middle part is provided with mandrel (2), the end of described mandrel (2) is provided with fork-shaped eccentric wheel (9), pressure-bearing cushion block (3) is disposed with between described base (1) and fork-shaped eccentric wheel (9), butterfly spring (6), extruding cushion block (7), eccentric wheel cushion block (8), described pressure-bearing cushion block (3), butterfly spring (6), extruding cushion block (7), eccentric wheel cushion block (8) is socketed on the external cylindrical surface of mandrel (2).
Further, described base (1) top is also provided with workpiece cushion block (4) for carrying workpiece (5), and workpiece cushion block (4) is ring-type, and its diameter is greater than pressure-bearing cushion block (3), is arranged in the outside of pressure-bearing cushion block (3).
The utility model simple structure and mounting or dismounting are convenient, the fixture life-span is long, cost is low, dismounting efficiency is high, effective, substantially increases productivity ratio, meets the needs of production.
Accompanying drawing explanation
Fig. 1 is the workpiece described in the utility model;
Fig. 2 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described further.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, a kind of boring grab of fast demountable, comprise base 1, mandrel 2 is provided with in the middle part of base 1, the end of mandrel 2 is provided with fork-shaped eccentric wheel 9, be disposed with pressure-bearing cushion block 3, butterfly spring 6 between base 1 and fork-shaped eccentric wheel 9, extrude cushion block 7, eccentric wheel cushion block 8, described pressure-bearing cushion block 3, butterfly spring 6, extruding cushion block 7, eccentric wheel cushion block 8 are socketed on the external cylindrical surface of mandrel 2.
Embodiment, the utility model first assembles fixture when using, load onto workpiece 5, then the round handle of fork-shaped eccentric wheel 9 is entered with a jacket casing, toward pressing down, rotate fork-shaped eccentric wheel 9 namely by eccentric wheel cushion block 8 and extruding cushion block 7, disk spring 6 to be compressed, make it diameter and swell, from inner surface swelling workpiece 5.Take off sleeve then start boring, after having bored hole, then overlap upper bush fork-shaped eccentric wheel 9 circle handle up lift, can unclamp, disk spring 6 rebounds automatically, and diameter diminishes, thus easily takes off workpiece 5.Owing to time-consumingly need not remove nutting, mounting or dismounting field measurement that workpiece is taken time is about 8s/ part.
In the present embodiment, the drilling axial force produced during boring, perpendicular to workpiece cushion block 4 upper surface, is directly born by workpiece cushion block 4.Drilling torque can make workpiece rotate, and for preventing workpiece from rotating, fixture clamping mechanism will have enough moment of frictions.Clamping force is controlled by eccentric compression degree, processing test on actual lathe, as long as this fixture a little firmly presses down fork-shaped eccentric wheel 9 circle, handle just can ensure processing request.
In the present embodiment, because fork-shaped eccentric wheel 9 and eccentric wheel cushion block 8 rub, for improving hardness and service life, adopt 20 steel by standard-required, carburizing depth 0.8 ~ 1.2mm, after heat treatment, hardness can reach HRC58 ~ 64.Because mandrel 2 eliminates screw thread, easy to process, heat treatment is because considering that screw thread protection also seems relatively easy.
Claims (3)
