Abstract
The invention relates to the technical field of fixtures, in particular to an expansion fixture device. The expansion fixture device is characterized by being composed of a pull rod, flat section bodies, extension springs, a wedge block and a fixture body. A center through hole is formed inside the fixture body, and the pull rod is arranged inside the center through hole. The outer surface of the right side of the fixture body is provided with six evenly-distributed axial long grooves in a milling mode, and the six flat section bodies capable of forming a complete circle are arranged in the axial long grooves. The exterior of each flat section body is provided with a groove, and the extension springs are arranged in the grooves in a sleeved mode. The lower surface of each flat section body is provided with a conical surface. The wedge block is arranged in the center hole of the fixture body, connected with the pull rod through threads and provided with six evenly-distributed inclined grooves which are matched with the conical surfaces of the lower portions of the flat section bodies respectively, and a hexagon screw head is welded to the right end face of the wedge block. The expansion fixture device is simple in structure, and the wedge block is of a complete circle type.
Description
Technical field
The present invention relates to a kind of clamp art, particularly relate to a kind of outer swollen grip device.
Background technology
Man-hour is added at processing work, sometimes to use outer swollen self-centering fixture, present fixture is in inner hole of workpiece fine finishining, existing outer swollen fixture easily makes the inner hole surface after fine finishining injured, the fragile material parts such as cast iron even can be made to occur slight crack, when workpiece is thin, yielding, make the cylindrical after processing remain the shape of distortion.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of structure simple, the outer swollen grip device of wedge type block whole-round.
The technical scheme solved the problems of the technologies described above is as follows:
Outer swollen grip device, comprise pull bar, flat lobe body, extension spring, wedge type block and clamp body composition, clamp body inside is provided with central through hole, pull bar arranges central through hole inside, on the right side of described clamp body, outer surface mills out six all axial elongated slots not, the flat lobe body that six can form wholecircle is provided with in axial elongated slot, the external groove offering suit extension spring of flat lobe, extension spring is provided with in groove, described flat lobe body lower surface is provided with the conical surface, wedge type block is placed in clamp body centre bore, be connected with pull rod screw, wedge is provided with six uniform skewed slots, coordinate with flat lobe body lower tapered surface respectively, described wedge right side is welded with a hex screw head.
Described clamp body right side is connected with dust plug.
Ring flange is provided with on the left of described clamp body.
Adopt such scheme, when the oil cylinder being arranged on lathe spindle rear end pulls wedge left, by coordinating the effect of the conical surface, wedge forces flat lobe body to expand outwardly, with the periphery swelling workpiece close to wholecircle, ensure the surface smoothness of fine finishining endoporus, when pull bar promotion wedge is moved to the left, under the effect of extension spring, flat springs shrinks, and contact with wedge all the time, workpiece can be taken down.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A schematic diagram of the present invention.
Detailed description of the invention
As shown in the figure, outer swollen grip device, comprise pull bar 1, flat lobe body 2, extension spring 3, wedge type block 4 and clamp body 5 form, clamp body 5 inside is provided with central through hole, pull bar 1 arranges central through hole inside, on the right side of clamp body 5, outer surface mills out six all axial elongated slots not, the flat lobe body 2 that six can form wholecircle is provided with in axial elongated slot, wholecircle shape can ensure inner hole of workpiece surface quality, the groove of suit extension spring 3 is offered outside flat lobe body 2, extension spring 3 is provided with in groove, six flat lobe bodies 2 are received and are forced together by two extension springs 3, unlikely separation, flat lobe body 2 lower surface is provided with the conical surface, wedge type block 4 is placed in clamp body centre bore, be threaded with pull bar 1, wedge 4 is provided with six uniform skewed slots, coordinate with flat lobe body 2 lower tapered surface respectively, when the oil cylinder being arranged on lathe spindle rear end pulls wedge 4 left, by coordinating the effect of the conical surface, wedge 4 forces flat lobe body 2 to expand outwardly, with the periphery swelling workpiece close to wholecircle, ensure the surface smoothness of fine finishining endoporus, when pull bar 1 promote wedge 4 be moved to the left time, under the effect of extension spring 3, flat lobe body 2 shrinks, and contact with wedge 4 all the time, workpiece can be taken down, wedge 4 right side is welded with a hex screw head 6, the inside and outside seat of hex screw head 6 is regulated by spanner, thus ensure the initial bulk of flat lobe body 2, for the workpiece of swelling different inner diameters size, compact conformation of the present invention, also uncomplicated, easy to operate, inner hole of workpiece surface quality can be ensured and avoid thin-wall workpiece to be out of shape.
Preferably, clamp body right side is connected with dust plug 7, can prevent dust from entering clamp body inside, improves the practical Stability of clamp body.
Further, on the left of clamp body, be provided with ring flange 8, be convenient to fixture to be contained on the flange before machine tool chief axis.
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.
