Compared with the prior art, the support retaining frame has the advantages and beneficial effects that the stability is good, the operation is convenient, the cost is low, and the support retaining frame adapted to the change of the caliber of the workpiece can be used to replace all traditional fixture tools.
Description
Technical field
The utility model relates to and supports solid frame, and is primarily aimed at the solid frame of support that adaptation workpiece bore that the workpiece that is useful for different bores designs changes.
Background technology
For the butt joint operation of heavy caliber, elongated pipeline workpiece, two elongated pipeline workpiece need adopt machine tool to make its butt joint generally speaking, generally are to adopt welding manner, perhaps screw thread docking mode.
No matter adopt above-mentioned which kind of docking mode, because the length restriction of its workpiece, and in the process of butt joint, will certainly cause bigger concussion, and the size of its shock range will inevitably have a negative impact to the butt joint operation of workpiece, and its influence has: one, operational difficulties; Two, butt joint is insecure; Three, arbitrarily workpiece is caused damage, four, make workpiece produce distortion easily; For these reasons, we need use setting tool, will dock workpiece earlier and fix, and then dock operation; The existing fixed instrument has only the support effect, does not have the fixed clamp effect.
Simultaneously, the said fixing instrument mainly is that the workpiece of each model need be equipped with a corresponding setting tool to the workpiece of different tube diameters size, and neither one only adopts a kind of setting tool just can accomplish the butt joint operation of different workpieces.
The utility model content
The purpose of the utility model is to provide a kind of workpiece of different caliber size, solid frame of support that can carry out the adaptation workpiece bore variation of fixed clamp effect to workpiece of being useful for.
The utility model implementation is following: adapt to the solid frame of support that the workpiece bore changes; Mainly constitute by supporting solid support body and being arranged on the following ejection device that supports solid support body top; The solid support body top of said support has breach; Following ejection device is arranged on gap position, and ejection device is connected through the solid support body top of connector and support down.
The solid support body of said support is the U-shaped support body; Its inner concave is provided with a guide rail; Be arranged with two sliding support pieces on the said guide rail, and two sliding support pieces bottom is connected with the sliding screw rod in top respectively, the sliding screw rod in said top runs through and supports solid support body and extend to that to support solid support body outside.
Said sliding support piece upper surface is the inclined-plane, and said inclined-plane offers some clamp groove, and is provided with pulley in the said clamp groove.
The angle span that said sliding support piece upper surface and horizontal line constitute is: 20 ° to 80 °.
Said ejection device down comprises the boss that is positioned at the solid support body top of support breach, and the axial location of said boss offers through hole, and device has push rod in the said through hole, and said push rod top and bottom are connected with rotating disk and overhead pulley respectively.
The transverse cross-sectional shape of said boss is trapezoidal.
The center of circle connecting line of said overhead pulley and two pulleys constitutes an isosceles triangle, and the focus point of overhead pulley and two pulleys is in the same plane.
Said connector comprises rotation jack-post and rotational pin, and all support body is connected said rotation jack-post through following ejection device and with supporting admittedly with rotational pin.
The operation principle of the utility model is: earlier rotational pin is unclamped, and rotate with supporting solid support body tie point along rotational pin, be about to rotational pin and shut down; To descend ejection device along being that the center of circle is rotated with the rotation jack-post then, the breach that can will support solid support body upper end reveals to be put out, at this moment; Use hoisting apparatus, work rest is located at the interior recess that supports solid support body, and makes workpiece contact with pulley; Be about to workpiece and be shelved on the pulley, will descend ejection device to circle round then, the sealing breach; Rotate rotating disk simultaneously, make rotating disk drive push rod and overhead pulley, when the overhead pulley with stop dial rotation after workpiece closely contacts.
After above-mentioned work is accomplished, when there is deviation in workpiece with the horizontal level that needs welding or screw thread to dock, can make the sliding screw rod in top drive the sliding support piece and on guide rail, slide through rotating the sliding screw rod in top, reach the adjustment level height with this.
Further, when the solid frame of the support that adapts to the variation of workpiece bore did not reach the bore of required workpiece, we can also be hyperphoric to another clamp groove with pulley.Change the leg-of-mutton length of side of the center of circle connecting line formation of overhead pulley and two pulleys, thereby change this inscribed circle of a triangle size, reach the purpose that satisfies the workpiece bore at last.
The above-mentioned course of work, the overhead pulley need keep closely contacting with two pulleys all the time with workpiece.Reach fixed clamp effect with this to workpiece.
The utility model compared with prior art has the following advantages and beneficial effect: stability is good, and is easy to operate, and cost is low, and an available solid frame of support that adapts to the variation of workpiece bore can replace existing all setting tools.
