Five, detailed description of the invention
Below in conjunction with embodiment, further describe the present invention, following examples are intended to the present invention instead of limitation of the invention further are described.The steps include:
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1-5 is an embodiment of the present utility model, illustrate the present embodiment by reference to the accompanying drawings, include ringfeder 1, the core 2 that rises, tension bolt 3, backing plate 4, spring 5, housing screw 6, screw 7, positioning sleeve 8 and anti-rotating hole 9, tie-plate 11.
Inner surface and the outer surface of the core 2 that rises of ringfeder 1 are respectively arranged with cone angle with cone to identical taper dignity, towards processing work 10 direction at the bottom of the cone of the taper dignity of ringfeder 1 and the core 2 that rises, ringfeder 1 and rising between core 2 by taper dignity mutually squeeze flow, the end lateral surface that ringfeder 1 has taper dignity is sleeved on the inner surface of processing work 10, tension bolt 3 is connected to through the backing plate 4 of ringfeder 1 end the internal thread risen on core 2, at tension bolt 3 and the pocketed springs 5 between core 2 that rises, spring 5 one end withstands on backing plate 4, the other end withstands on and rises on the end face of core 2, backing plate 4 is fixed on ringfeder 1 by housing screw 6.
In this example, the axial direction of the taper dignity of ringfeder 1 arranges 8 gaps 12, described gap 12 has opening in the cone bottom of ringfeder 1.
In this example, to be provided with at ringfeder 1 and rising the screw 7 that the core 2 that prevents from rising rotates in tensioner process between core 2, screw 7 one end is connected on ringfeder 1, and other end end is connected with core 2 contact that rises by being arranged on the anti-rotating hole 9 risen on core 2 lateral surface.
In this example, between workpiece and ringfeder 1, be provided with the positioning sleeve 8 be sleeved on ringfeder 1.
In this example, the tie-plate 11 that can be connected with lathe is provided with in ringfeder 1 one end.
When clamping processing work, rotate tension bolt 3, tension bolt 3 drives the core 2 that rises of its link to move toward the opposite direction of processing work, due in the taper dignity being provided with between core 2 and ringfeder 1 and mutually pressing that rises, rise by core 2 in the process of motion in the other direction, can constantly mutually press between taper dignity, thus make the outer surface of ringfeder 1 that the elastic deformation of radial direction occur, thus its outer surface slowly be pressed on processing work; Owing to ringfeder 1 devising the gap 12 with opening, one end that ringfeder 1 has a taper surface is divided into the fraction at some intervals, does not have circumferential active force between some fractions, more easily elastomeric radial occurs in the process that they are extruded by the core 2 that rises; When completion of processing, counter-rotation tension bolt 3, and under the thrust of spring 5, the core 2 that rises moves toward the direction of processing work, the taper surface risen between core 2 and ringfeder 1 is separated gradually, thus the outer surface elastic deformation of ringfeder 1 recovers, and then its outer surface is made to depart from the inner surface of processing work.
The utility model has following characteristics:
1, owing to devising ringfeder 1, rise core 2 and linkage, controlling by linkage the core 2 that rises and make ringfeder 1 be squeezed on the inner surface of processing work, no longer the clamping of processing work effectively not being controlled, because this enhancing the fastness of processing work.
2, due to the tapered squeezing face devising ringfeder 1 and rise between core 2, make extruding force be evenly distributed on processing work, processing work should not be deformed in the process of clamping, effectively improve the machining accuracy of processing work.
3, owing to devising the gap 12 with opening, one end that ringfeder 1 has taper dignity is divided into the fraction at some intervals, space is there is between some fractions, so there is not circumferential active force between them, more easily there is elastomeric radial in the process that they are extruded by the core 2 that rises, thus accelerate tensioner process.
4, owing to devising the interlinked mechanism including tension bolt 3, backing plate 4, spring 5 and the core 2 that rises, conveniently can realize the tensioner of processing work and unclamp, having adapted to the operation requirements of this swelling device, be adapted to the miniaturization structure of swelling device.
5, owing to devising movable backing plate 4, facilitate installation and the connection of tension bolt 3 and the core 2 that rises, meet the installation requirement of this swelling device.
6, due to the anti-rotating hole 9 devising screw 7 and rise on core 2, the core 2 relative ringfeder 1 in tensioner with release process that can prevent from rising rotates, and improves the operability of tension mechanism; And can the axial length of appropriate design anti-rotating hole 9, also the axial displacement length risen between core 2 and ringfeder 1 can effectively be controlled, thus the effective extruding force of control action on processing work, directly processing work is enclosed within desired location, and then improves the operating efficiency of tensioner workpiece.
7, owing to devising positioning sleeve 8, design the size of positioning sleeve according to processing work, directly processing work is sleeved on ringfeder during tensioner, improve the working (machining) efficiency of processing work.
8, owing to devising tie-plate 11, this device can be arranged on lathe spindle, dividing head and machining center the 4th by this dish and axle uses, meet the versatility requirement of this swelling device.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
