Abstract
The invention relates to a combined clamping method for heavy structural parts. The method includes the steps: (1) establishing a clamping coordinate system by placing a pad box on a worktable, matching a lower plane of the pad box with a worktable top, connecting an upper plane of the pad box with a right-angle bent plate, ensuring planar uniformity of a clamping surface of the right-angle bent plate to reach +/-0.03mm, placing an equal-height pad on the worktable, spacing the equal-height pad from the pad box for a certain distance and ensuring uniform height of the equal-height pad with the allowance ranging from -0.02mm to +0.02mm; (2) placing a workpiece on the equal-height pad, leading one surface of the workpiece to flatly lean towards the right-angle bent plate, tightly pressing the workpiece by the aid of a pressing plate and laterally fixing two sides of the workpiece by the aid of a lateral pressing plate; and (3) adjusting X-axis linearity of the workpiece by the aid of the pressing plate and a jack at a position B on the lower side of the workpiece, adjusting Y-axis linearity of the workpiece by the aid of the lateral pressing plate and ensuring front-back Z-axis 0.03mm planar precision by the aid of the large right-angle bent plate. By the aid of the method, large and thin workpieces can be firmly clamped, cubic clamping and machining of workpieces such as a movable worktable, super-wide vertical columns and the like are realized possibly.
Description
Technical field

Background technology
In heavy machine tool machined part technology, being installed always is a problem of difficulty relatively.Along with the development of heavy industry, the size of part and weight are increasing and profile is irregular relatively.In order to satisfy the heavy machine machining accuracy, enhance productivity, improve workman's working condition, to reduce production costs.So in being installed, part is stepped up, locatees, auxiliary novel means and the frock that is installed arisen at the historic moment.
The parts that are used for working fluid press product like the part of some super-big and overweights such as pillar, travelling table, veneer and thickness relative thin, because the part of large-scale and thin thickness can't safe cube is installed, propose a kind of combined type chucking method hereby.
Summary of the invention
The present invention can't safe cube of technical problem that is installed provide a kind of heavy type structure part combined type chucking method for solving the part owing to large-scale and thin thickness that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of heavy type structure part combined type chucking method, it is characterized in that, and comprise the steps:
(1) sets up the coordinate system that is installed: will fill up case and be positioned on the workbench; Said pad lower box part plane cooperates and has the T type groove location of keyway and workbench with the table top of workbench, the plane is connected with large-scale angle block of right angle through stud on the pad case, and said angle block of right angle bottom utilizes the keyway location with the pad case; Utilize lathe to draw table; Guarantee that the large-scale angle block of right angle facial plane uniformity that is installed reaches ± 0.03mm, contour pad is positioned on the workbench, distance pad case certain distance; Utilize lathe to draw table to guarantee that the height of contour pad is consistent, franchise ± 0.02mm;
(2) work piece vertically is put on the contour pad, makes the one side of workpiece rely on angle block of right angle and by flat, utilize six groups of studs and pressing plate with Work-sheet pressing, side direction utilizes four side guides that the workpiece both sides are fixed;
(3) utilize the X axle linearity of the jack adjustment workpiece at pressing plate and workpiece downside B place, utilize the Y axle linearity of side guide adjustment workpiece, front and back Z axle relies on large-scale angle block of right angle self 0.03mm plane precision to guarantee voluntarily.
The present invention can also adopt following technical measures:
The thickest position A of said workpiece sentences the stable and safety of overhead traveling crane hook auxiliary component.
The quantity of said pad case, angle block of right angle and contour pad is consistent, is three.
Said contour pad is 800mm apart from the distance of pad case.
The quantity of said side guide is four.
Advantage and good effect that the present invention has are: the present invention makes workpiece large-scale and the thickness relative thin be able to firm being installed, and the processing that cube is installed of workpiece such as travelling table, ultra wide column possibly become.The present invention buys or makes the more fund of enlarged bent plate from having saved economically; Make original large-scale bent plate bring into play bigger effect; With most economical safe method; The Y axle range of work that has realized new machine is extended to 5 meters (7 meters of lathe Y axle ranges of work), for actual production processing has solved difficulty.
Description of drawings
Fig. 1 is the present invention's schematic perspective view that is installed;
Fig. 2 is an I enlarged drawing among Fig. 1;
Fig. 3 is an E enlarged drawing among Fig. 1.
Among the figure: the 1st, workpiece, the 2nd, pressing plate, the 3rd, side guide, the 4th, angle block of right angle, the 5th, pad case, the 6th, workbench, the 7th, contour pad.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
A kind of heavy type structure part combined type chucking method comprises following step:
(1) sets up the coordinate system that is installed: three pad casees 5 are positioned on the workbench 6; Pad case 5 lower flat cooperate and have keyway and workbench 6 with the table top of workbench 6 T type groove location utilizes stud to be connected with three large-scale angle block of right angle 4, and angle block of right angle 4 bottoms utilize the keyway location with pad case 5; Make the integral body face height that is installed reach 5000 (bent plate height 3000, pad case height 2000); Utilize lathe to draw table, guarantee that three large-scale angle block of right angle 4 facial plane uniformity that is installed reaches ± 0.03mm, is positioned over three 500mm contour pads 7 on the workbench 6; Distance pad case 5 about 800mm; Utilize lathe to draw table to guarantee that the height of contour pad 7 is consistent, franchise ± 0.02mm, the coordinate system that so far is installed is set up.
(2) workpiece 1 is stood up on contour pad 7 by shown in the accompanying drawing 1, make the one side of workpiece 1 rely on angle block of right angle 4 and by flat.Utilize six groups of studs and pressing plate 2 that workpiece 1 is compressed, side direction utilizes four side guides 3 that workpiece 1 both sides are fixed, and so far side guide 3 and 2 couples of workpiece XYZ of pressing plate three-dimensional have all played free degree restriction.
(3) utilize the X axle linearity of the jack adjustment workpiece 1 at pressing plate 2 and downside B place, utilize the Y axle linearity of side guide 3 adjustment workpiece 1, front and back Z axle then relies on large-scale angle block of right angle 4 self 0.03mm plane precision to guarantee voluntarily.The thickest workpiece 1 top A sentences the stable and safety of overhead traveling crane hook auxiliary component.So far the oversize workpiece be installed finish realized constraint each to the free degree and the purpose of stepping up.
