The invention discloses a machine tool part, and particularly relates to a thin-walled part fixing device which comprises a supporting table and a pressing rod. A through hole is formed in the geometric center of the supporting table, a pressing plate is arranged at one end of the pressing rod, the other end of the pressing rod penetrates the through hole and is slidably connected with the through hole, a first tension ring, a spring and a second tension ring are arranged on the periphery of the pressing rod, the spring is positioned between the first tension ring and the second tension ring, the second tension ring is abutted to the pressing plate, and the first tension ring is abutted to the supporting table. The thin-walled part fixing device has the advantages that the thin-walled part fixing device is simple to operate and high in use efficiency, and a thin-walled part cannot deform.
Description
Technical field
The present invention relates to a kind of machine tool component, be specifically related to a kind of fixture of thin-walled parts.
Background technology
In mechanical processing process, usually need first workpiece to be fixed by clamping device, make workpiece obtain the tram with respect to lathe and cutter, then workpiece is processed.By clamping device, workpiece is fixed, because the positional precision of workpiece is guaranteed by clamping device, can not be subject to the impact of workman's technical merit, so Workpiece Machining Accuracy is high and steady quality, and then the rate of reducing the number of rejects and seconds, guaranteed the quality of product; Because clamping device can make workpiece location and clamping rapidly, reduce unproductive time significantly again, improved production efficiency.So both can guarantee mechanical processing quality, and enhance productivity, reduce labor intensity, can reduce the excessive demand to workman's technology again.Because processing needs, some workpiece will fix by hand actuable clamping device conventionally.But peculiar part is added to man-hour, clamping device is had to certain requirement.Such as thin-walled parts adds man-hour, it is fixedly a very thorny job.Because part wall is very thin, if fixing dynamics is excessive, easily make thin-walled parts distortion; If fixing dynamics is too small, thin-walled parts cannot be fixed.
Summary of the invention
The technical problem to be solved in the present invention comprises: provide a kind of simple to operate, service efficiency is high and can not make thin-walled parts produce the fixture of distortion.
In order to solve the problems of the technologies described above, the invention provides a kind of fixture of thin-walled parts, comprise brace table and depression bar, described brace table geometric center place is provided with through hole; Depression bar one end is provided with pressing plate, and the other end passes through hole and is slidably connected with through hole; Depression bar is arranged with the first tension ring, spring and the second tension ring outward, and spring is between the first tension ring and the second tension ring, and the second tension ring and pressing plate offset, and the first tension ring and brace table offset.
Adopt the fixture of the thin-walled parts of such scheme, after adopting two tension ring crimps, in radial direction, produce the expansion of homogeneous, and then by thin-walled parts inwall tensioner, be fixed.So thin-walled parts can excessively because of fixing dynamics not produce deformation, and then the further processing of impact to part.And simple to operate, service efficiency is high.
As preferred version, between described spring and the first tension ring and the second tension ring, be respectively equipped with compressing tablet.Adopt after such structure, can make the first tension ring and the second tension ring stressed evenly, extend its service life.
As preferred version, also comprise pull bar, described depression bar is hinged through one end and movable rod one end of through hole, and the movable rod other end and pull bar mid portion are hinged; Pull bar one end and workbench are hinged.The other end of compressing pull bar can drive movable rod, and then pull bar is moved, and makes pressing plate push the first tension ring, spring and the second tension ring, finally by part inwall tensioner.Be convenient to pull bar to control.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fixture embodiment of thin-walled parts of the present invention;
Fig. 2 be the fixture embodiment of thin-walled parts of the present invention by workpiece the schematic diagram fixedly time.
The specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is described in further detail:
The fixture of thin-walled parts as shown in Figure 1, comprises brace table 8 and depression bar 2, and described brace table 8 geometric center places are provided with boss 7, and boss 7 geometric center places are provided with through hole, and brace table 8 is structure as a whole with boss 7.Depression bar 2 one end are provided with pressing plate 1, and pressing plate 1 is provided with infrared alignment device (not shown); Depression bar 2 other ends are hinged through through hole and movable rod 9 one end, and movable rod 9 other ends and pull bar 10 mid portions are hinged; Pull bar 10 one end and workbench are hinged, and the other end is fixedly connected with pedal (not shown).Depression bar 2 is outer is arranged with the first tension ring 6, spring 5 and the second tension ring 4, and spring 5 is between the first tension ring 6 and the second tension ring 4; Between spring 5 and the first tension ring 6 and the second tension ring 4, be respectively equipped with compressing tablet (not shown).Pull down dynamic pressure bar 2, can make pressing plate 1 extruding the second tension ring 4 and make it distortion, and then by spring 5 compressions, finally make the first tension ring 6 distortion.
As shown in Figure 2, during use, after thin-walled parts 3 is placed on brace table 8, by downward pushes pedals, drive movable rod 9, depression bar 2 is moved down, and then make pressing plate 1 extruding the second tension ring 4 and make it distortion, the second tension ring 4 is by spring 5 compressions, spring 5 compressing the first tension rings 6 make it distortion, and two tension rings are extruded the expansion that produces homogeneous in radial direction after distortion, finally by thin-walled parts 3 inwall tensioners.By the infrared alignment device on pressing plate 1, can, by thin-walled parts 3 auto-alignments, then just can process thin-walled parts 3.After thin-walled parts 3 machines, remove the power being applied on pedal, the first tension ring 6, spring 5 and the second tension ring 4 are under the effect of self restoring force, promoting pressing plate 1 moves up, and then drive successively depression bar 2, movable rod 9 and pull bar 10, make the fixture of thin-walled parts be returned to original state, the thin-walled parts processing 3 is taken off.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
