Abstract

The invention provides a vacuum adsorbing clamp for fixedly clamping a thin-walled workpiece, suitable for adsorbing and clamping a workpiece with a complicated appearance. The vacuum adsorbing clamp is provided with a supporting base, wherein the base is provided with a plurality of supporting columns capable of adjusting supporting positions, the heights of the supporting columns can be adjusted, the top ends of the supporting columns are provided with universal-connection suckers, the cavities of the suckers are communicated with a negative pressure pump, and the long-distance, multi-path, all-position clamping requirement of the complicated workpiece can be met.

Description

A kind of vacuum adsorption fixture of thin-wall workpiece
Technical field:
The present invention relates to thin-wall workpiece and add fixed clamp workpiece technical field in man-hour, specifically a kind of vacuum suction method and the vacuum adsorption fixture of sucker to thin-wall workpiece that utilize
Technical background:
Existing mechanical processing industry, a lot of workpiece belong to thin plate class, just because of workpiece is thin, adopt traditional method clamping in side surface of workpiece, very easily cause workpiece deformation and surface indentation, cannot meet machining accuracy and matching requirements.The problem existing in order to solve traditional clamp method, has occurred utilizing vacuum adsorption force to fix the vacuum adsorption fixture of workpiece.
Current vacuum adsorption fixture has two kinds, one: adopt all-in-one-piece vacuum suction structure, be applicable to the workpiece of plane, as the overall vacuum absorption platform in numerically controlled processing equipment; Its two: adopt modular vacuum suction structure, be applicable to flat board and with the aircraft skin class workpiece of curvature.Workpiece for picture aircraft cabin class, not only with plane but also with the workpiece of curvature, processing process in because workpiece is larger at the volume in space, adopting above two kinds of modes all cannot realize sucker matches with the shape and structure of workpiece, cannot realize accurate location, be difficult to guarantee the machining accuracy of workpiece.
Summary of the invention:
The object of this invention is to provide a kind of vacuum adsorption fixture that can fixed clamp thin-wall workpiece, applicable to the workpiece of complex contour is adsorbed to clamping.
A kind of vacuum adsorption fixture of thin-wall workpiece, it is characterized in that having a supporting base, be provided with a plurality of support columns that can regulate Support Position on pedestal, the height of this support column can regulate, on the top of support column, be provided with the sucker of universal connection, the dish chamber of sucker is communicated with negative pressure pump.
For applicable different support zone, described supporting base is provided with a plurality of continuous support column fixing holes.
Simultaneously in order to increase stability and the rigidity of support of support, described supporting base is a rigid structure being comprised of two-layer connecting plate preferably, on levels connecting plate, be equipped with coaxial connecting hole, mate with the external diameter of support column in aperture on the connecting plate of upper strata, and mate with the connecting key of support column lower end in the aperture on lower floor's connecting plate.
It is adjustable that the application's advantage is that fixture plays the distance of support column of fixation to workpiece, the height of support column is adjustable, the universal complex appearance that can better adapt to workpiece that is connected between sucker and support column, the dish chamber of sucker and negative pressure pump or negative pressure source are communicated with to be beneficial to and strengthen the pretightening force of sucker to workpiece, the satisfied needs to the long distance of complex part, multipath, comprehensive clamping.
Below in conjunction with embodiment accompanying drawing, this application is described in further detail:
Accompanying drawing explanation
Fig. 1 is vacuum adsorption fixture structural representation of the present invention
The structural representation that Fig. 2 support column is connected with pedestal
The structural representation of Fig. 3 sucker
Fig. 4 is that vacuum adsorption fixture of the present invention is used view
In figure, numbering is as follows: 1. supporting base, 2. support column, 3. Universal connecting mechanism, 4. sucker, 5. backstay, 6. negative pressure pump, 7. workpiece, 8 circular holes, 9 keyholes, 10 centre bores
The specific embodiment
Referring to accompanying drawing, the vacuum adsorption fixture of thin-wall workpiece, has a supporting base 1, on pedestal, be provided with a plurality of support columns 2 that can regulate Support Position, the height of this support column can regulate, and is provided with the sucker 4 of universal connection on the top of support column, and the dish chamber of sucker is communicated with negative pressure pump 6.
In enforcement, for applicable different support zone, guarantee that stability and the strength support pedestal 1 of supporting base is provided with a plurality of continuous support column fixing holes; While supporting base 1 is a rigid structure being comprised of two-layer connecting plate preferably, on levels connecting plate, be equipped with coaxial connecting hole, hole on the connecting plate of upper strata is a kind of circular hole 8, mate with the external diameter of support column in its aperture, hole on lower floor's connecting plate is a kind of polygonal keyhole 9, and mate with the connecting key of support column lower end in its hole shape and aperture.As shown in Figure 2.
Support column 2 can adopt the telescopic mechanical transmission method combinings such as gear to realize highly adjustable; According to the difference of the complex situations of processing work and size, the support column 2 of varying number can be installed on pedestal 1; Sucker 4 can be installed in the top of support column 2; Support column 2 can be connected with Universal connecting mechanism 3, and sucker 4 can be installed in the top of Universal connecting mechanism 3; Universal connecting mechanism 3 can be comprised of " L " type parts and " U " type parts, and the mechanism that also can realize direction conversion by other forms; There is a centre bore 10 at sucker 4 Pan Qiang centers, and this centre bore 10 is connected with negative pressure pump 6 by breather pipe, by the vacuum state in the control valve adjusting sucker dish chamber of negative pressure pump; Sucker 4 echos on the surface of workpiece 7, and when the state of control valve switch in opening, the dish chamber of sucker 4 starts to form vacuum, and sucker 4 is bonded together under atmospheric effect with workpiece 7, realizes absorption fixing; Backstay 5 adopts the structure same with support column 2 to be connected with pedestal 1, by being connected with the locating hole on workpiece 7, realizes the location of workpiece, can adjust as required the quantity of backstay.
