Abstract
The utility model relates to a thin-wall special cylindrical piece externally supporting fixture, which comprises a worktable and a fixture, wherein the fixture is fixed on the worktable and has an axial through opening, a shaft seat is fixed on one side edge of the fixture, a vertical shaft is arranged on the shaft seat, a movable sleeve is sleeved on the vertical shaft, and the movable sleeve moves radically along the vertical shaft; and a wedge frame is fixed on the worktable on the outer side of the shaft seat position, a wedge slides up and down axially in the wedge frame, and the wedge pushes the movable sleeve to shift radially when shifting up and down in the wedge frame. In the utility model, the structure can be made simply, the design is scientific and reasonable, it is convenient and quick to use the fixture, the multi-pass necking quality of thin-wall special cylindrical pieces is assured effectively, and the fixture is a novel automatic clamping and loosing structure and is particularly suitable for use in the processing of various thin-call special cylindrical pieces.
Description
Affiliated field
The utility model belongs to the mechanical clamp field, relates in particular to the outer support fixture of a kind of thin-wall special-shaped cylindrical member.
Background technology
Thin-wall special-shaped cylindrical member is to make the blank workpiece of kettle etc., be aluminium material, because its light weight, relative intensity is lower, when pressure processing, if anchor clamps are bad, very easily cause the workpiece buckling deformation, make the thin-wall tube-shaped element bottom produce depressed deformation, the height dimension uniformity is relatively poor, influences workpiece quality percent defective height; Especially add man-hour in the multiple tracks reducing, its quality is difficult to guarantee especially.
By retrieval, do not find the open source literature that addresses this problem as yet.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of thin-wall special-shaped cylindrical member outer support fixture, and this clamp structure is simple, reasonable in design, easy to use, the life-span is longer, and can effectively improve thin-wall special-shaped cylindrical member and carry out the quality and stability that the multiple tracks reducing adds man-hour.
The utility model solves its technical problem and is achieved through the following technical solutions:
The outer support fixture of a kind of thin-wall special-shaped cylindrical member, comprise workbench and anchor clamps, anchor clamps are packed on the workbench, it is characterized in that: the axial latus rectum of described anchor clamps is shaped on opening, side at anchor clamps is fixed with an axle bed, one d-axis is installed on this axle bed, is set with a movable sleeve on this d-axis, this is actively set on the d-axis and moves radially; Be fixed with a voussoir frame on the workbench in the axle bed position outside, this voussoir is axial upper and lower slide displacement in the voussoir frame, and this voussoir promotes the movable sleeve radial displacement during upper and lower displacement in the voussoir frame.
And, describedly in the voussoir frame of axle bed direction, make a dovetail groove, the voussoir upper and lower displacement of in this dovetail groove, sliding.
Advantage of the present utility model and beneficial effect are:
1, these anchor clamps are when carrying out the multi-pass reducing to thin-wall tube-shaped element, for overcoming the workpiece unstable phenomenon, the clamping force of anchor clamps must be greater than necking force, and be operation automatically, accomplished the clamping force unanimity, improved the qualification rate of workpiece after the reducing of thin-wall tube-shaped element multi-pass, guarantee the thin-wall tube-shaped element bottom smooth, do not have a distortion, and the height dimension high conformity uses when being specially adapted to various thin-wall tube-shaped element automated production.
2, these anchor clamps adopt die steel material and after machined was made, assembling was installed on the workbench of automatic necking machine, during work, can finish the clamping of workpiece/unclamp automatically, the production efficiency height, and quality is good, and is simple to operate.
3, the utility model structure fabrication is simple, design science is reasonable, and is convenient to use, can guarantee effectively that thin-wall special-shaped cylindrical member carrying out multi-pass reducing quality, be a kind of novel automatic clamping/loose configuration, be specially adapted to various thin-wall tube-shaped elements and add the use in man-hour.

Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the right view (having omitted kettle workpiece and voussoir) of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
The outer support fixture of the related thin-wall special-shaped cylindrical member of the utility model is carrying out the automatic clamping that the multiple tracks reducing adds man-hour/unclamp used outer support fixture for thin-wall special-shaped cylindrical member, and present embodiment is a kind of portable aluminum closing in kettle.
The outer support fixture of a kind of thin-wall special-shaped cylindrical member, constitute by workbench 9, anchor clamps 3, voussoir 4, voussoir frame 8, movable sleeve 6, on workbench, install anchor clamps, these anchor clamps are the clevis tool that splits, promptly the axial latus rectum at anchor clamps is shaped on opening 2, by opening open and the closed clamp clamper in kettle workpiece 1, in the both sides of anchor clamps fastening bolt 11 is installed.Side at anchor clamps is fixed with an axle bed 5 by trip bolt 12, one d-axis 7 is installed on this axle bed, on this d-axis, be set with movable sleeve, this movable sleeve can move radially on d-axis, when movable sleeve moves radially, can radially apply radial load to anchor clamps, this radial load can make the opening closure of anchor clamps.The outside in the axle bed position, on workbench, install the voussoir frame by trip bolt 10, this voussoir frame is made a dovetail groove in the axle bed direction, in this dovetail groove, be slidingly fitted with voussoir, this voussoir is in the dovetail groove of voussoir frame during upper and lower displacement, can promote the movable sleeve radial displacement, have auto-lock function simultaneously.
Working method of the present utility model is:
Clamp: descending when the walking beam of automatic reducing forcing press, its ramming stem is to the voussoir Q that presses
1, voussoir is depressed, and promotion anchor clamps movable sleeve clamps workpiece.Since locking angle=8 ° 33 ', self-locking formed; After ramming stem was return, voussoir can not withdraw from, and finishes clamping work pieces, entered the reducing operation.
Unclamp: up when the forcing press walking beam, this moment, anchor clamps entered next station automatically by automatic necking machine pressure, and the oil cylinder of anchor clamps bottom is to the voussoir knock-pin Q that presses
2, voussoir is ejected, anchor clamps unclamp, and finish unclamp operation, enter the pickup operation.
Automatically the reducing forcing press up/once descending, promptly finish n=1 reducing, recirculation is once promptly finished n=2 reducing, so circulation, when n reducing reached dimensional requirement, entered pickup and operate this moment until workpiece, the reducing of end single-piece workpiece is operated; And so forth, but then continuous operation.
