Description
Technical field
The invention belongs to the thin slab assembly field, particularly relate to a kind of any curved sheet piece in plane location that is used for and clamp erecting device and method.
Background technology
Current era is epoch of changing fast, and the quick variation and the diversity of customer demand make people propose the requirement of efficient quick to the sheet member process and assemble.
At present, in the domestic sheet member assembling, adopt special tooling usually.Development trend along with present sheet member Assembling Production small lot, personalization; The use of this type frock just more and more is restricted; The cycle that its design is produced is longer; Adjustment difficulty, this present situation have restricted the raising of sheet member assembly quality such as some electronic products of China such as automobile, spacecraft radome fairing and efficient largely.
Existing circular arc class sheet member adopts mostly presses the special tooling that arc diameter is made, the flexibility adjustment function of incompatibility multiple diameter circular arc.When product specification changes, when needing the different-diameter circular arc, can only make new frock again, this is with regard to the manufacturing cost that has increased enterprise greatly, the lead time that has increased product.
Summary of the invention
Technical problem to be solved by this invention provides a kind of any curved sheet piece in plane location of being used for and clamps erecting device and method, solving when any curved sheet piece in plane process and assemble, the location of sheet member is clamped the problem of installing.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of any curved sheet piece in plane location that is used for to clamp erecting device; Form by flexible retainer, diameter changing device and soleplate; Be distributed with diameter changing device on the housing of soleplate; Described diameter changing device (200) is connected with soleplate (300) through pin or screw, and arranges in the arc-shapedly, and flexible retainer is positioned on the diameter changing device; 1 flexible retainer and links to each other through pin or screw on the rebound (202) of 2 diameter changing devices.
Flexible retainer is made up of main positioning clamping device, auxiliary locator and connection substrate.Main positioning clamping device links together through being connected substrate with auxiliary locator.Main positioning clamping device is made up of base, motor, shaft coupling, supporting seat, guide rod, leading screw, nut, main backstay, vacuum absorption device, and passes through base and be connected the substrate connection, and motor is installed in the base end face; Fixed supporting seat above the base, motor is connected with leading screw through shaft coupling, and nut is installed on the leading screw; Guide rod is installed on the base, and nut is connected with guide rod, simultaneously; Main backstay is installed on the nut; Its reverse extending line is through the same center of circle, and vacuum absorption device is installed within the main backstay, and vacuum absorption device has vacuum cup, vacuum generator, magnetic valve.
Auxiliary locator is made up of assist location bar, spring, box body, lid.Spring is contained in the box body, and the assist location bar is installed in the box body, and on spring, lid is installed on the box body.Four auxiliary locators are housed around the main positioning clamping device.
Diameter changing device is made up of drive unit, push rod, rebound.The connection substrate of flexible retainer is installed on two rebounds, and rebound is installed on the push rod separately, and push rod is installed on the drive unit separately.
Described a kind of any curved sheet piece in plane location that is used for clamps erecting device; The main mode that adopts a main location and four assist location; Backstay in the middle of promptly is main positioner, and the form through the leading screw guide rod realizes little feeding, to reach the arc position of expection; And through retaining mechanism locking, with deviation position under the effect that prevents power outside.The effect (can adjust the quantity of assist location according to actual needs) of playing supplemental support on every side through four auxiliary locators at this main positioner; This supplemental support is made up of spring and assist location bar; According to the difference of curve sheet member position, stroke is different.The clamping of sheet member relies on the vacuum absorption device of installing on main backstay top and realizes, helps like this processing and operation such as assembling at the outer surface of sheet member.
A kind of method of adjustment that is used for any curved sheet piece in plane location clamping erecting device: at first computer is controlled in the arc position input of needs; The control computer judge automatically each movement executing mechanism the distance that will move; And convert move distance into control signal, send to each movement executing mechanism.The drive unit of diameter changing device carries out motion in a big way under the effect of control signal, its kinematic accuracy is relatively low, and purpose is to realize large-scale adaptability.After diameter changing device motion put in place, the main positioning clamping device of flexible retainer began under the driving of control signal comparatively that accurate movement after each main positioning clamping device motion puts in place, thereby can fit to required circular arc to assigned address.The curve sheet member of correspondence is placed on this device, and the main backstay through flexible retainer positions, and adopts vacuum absorption device that sheet member is clamped afterwards.
Beneficial effect
Location when 1, the present invention adopts controlled flexible retainer, diameter changing device etc. to solve any curved sheet piece in plane installation clamps problem, is to have adaptability, is the frock that can satisfy any curved sheet piece in plane.
2, the present invention is the installation towards the different curvature circular arc, promptly is the mutual coordination through several flexible retainer, makes the anchor point match of each locator become the circular arc of required diameter.
3, the present invention has realized the accurate match of whole device for arc surface through main positioning clamping device, and clamps for the accurate location of sheet member.
4, the present invention has realized the supplemental support of whole device for the curve sheet member, the distortion of having avoided sheet member to cause because of poor rigidity through auxiliary locator.
5, the present invention has realized whole device in diametric variation in a big way through diameter changing device, has reached the requirement that adapts to the different-diameter circular arc.
