Abstract

The utility model relates to a welding mechanical fixture which can coaxially locate workpieces in a floating manner in the automobile manufacturing industry and particularly relates to a coaxial floating location tool for lug plate holes, wherein the coaxial floating location tool can lead a plurality of groups of lug plates to be located in a floating manner based on the holes and is conveniently used for welding a support-leg bracket component. The coaxial floating location tool comprises fundamental parts, such as a welding bench, centering round bars, guide blocks, and two groups of floating cross beams; four upright posts are mounted at four corners outside a component to be welded; the floating cross beams are hollowly sleeved in the upright posts and can be adjusted through vertically floating and moving along the upright posts; the guide blocks are mounted on the floating cross beams; the centering round bars can be inserted into location guide circular holes of the guide blocks so as to locate location holes of the component to be welded; and when profile sizes of the components to be welded are inconsistent, axial lines of the holes of the components can still be guaranteed to have the coaxiality because the floating cross beams control the positions of the axial lines.

Description

The coaxial unsteady positioning tool in otic placode hole

Technical field:

The utility model relates to can be realized in one type of automobile manufacture industry workpiece is carried out the unsteady location of axiality; The mechanical clamp of welding is meant that especially conveniently is applied to the coaxial unsteady positioning tool in otic placode hole how group otic placodes realization hole benchmark floats and locatees that makes that the supporting leg bracket component welds usefulness.

Background technology:

To the engineering automobiles vehicle in the welding of exclusive supporting leg groups of holders one class component;, regular meeting implements the problem of welding after running into the positioning and fixing of need floating to many groups otic placode realization hole benchmark again; Be in parallel position if can not guarantee the central axis of respectively organizing otic placode, will have a strong impact on total packing quality of assembly.

But in existing product or technology report; The product of this type of weld jig that weld assembly is carried out the unsteady location of hole benchmark or the report of technical elements are not also arranged; Therefore in operating at the scene; Often still rely on primitive operation methods such as coarse line, range estimation, having a strong impact on the processing quality of welding.

There are some related patent U.S. Patent No. to disclose some relevant imaginations of a plurality of parts being carried out axiality positioning fixture aspect at present; For example a patent No. is: " a kind of concentricity jig of flange mounting hole of placing vertically " of CN201863141U; Introduced a kind of method that guarantees the axiality of insulator flange mounting hole through the depth of parallelism between the assurance clamping plate; Another patent No. is: " a kind of concentricity jig of flange mounting hole " of CN201399744; Introduced and a kind ofly adopted semicircle pressing plate to have the hole that is complementary with flange mounting hole in the relevant position of pressing plate; When flange is connected with insulator glue; Two pressing plates compress at two ends, and are fastened on the horizontal plane through pull bar, and the hole on the pressing plate is corresponding with flange mounting hole respectively and with the axiality ensuring method of bolted; But these two kinds of structures all are a kind of single parts to be implemented the method for axiality location, can not satisfy needs described herein and solve the job requirement that many group spare parts carry out implementing after the accurate positioning and fixing of axiality welding simultaneously again.

Summary of the invention:

This is novel to provide a kind of and has realized that many group spare parts carry out the float novel clamp structures of location of axiality simultaneously.

The technical solution adopted for the present invention to solve the technical problems is:

This is novel by welding bench, and centering pole, guide pad and unsteady crossbeam essential part are formed, and four jiaos four root posts have been installed in the outside of assembly to be welded; Two groups of crossbeam skies that float are enclosed within the column; Can fluctuate along column and move adjustment, guide pad is installed on the crossbeam that floats, and guiding circular hole of its location usefulness pole that can supply to feel relieved inserts; The locating hole of treating weld assembly positions; When the profile of assembly to be welded is not of uniform size when causing, because therefore the crossbeam that floats, can guarantee still that position, the hole axial line of each assembly keeps axiality to the axial line control of position.

Therefore the basic functional principle of this structure is, through the crossbeam that floats the horizontal up-down adjustment of guide pad maintenance fixed thereon is moved, thereby makes each assembly that is positioned can guarantee axiality.

The invention has the beneficial effects as follows:

This novel axiality positioning fixture organization plan that a kind of novelty is provided can be realized the control to the axiality positioning accuracy easily in weld jig.

Description of drawings:

This is novel by welding bench, and essential parts such as centering pole, guide pad and unsteady crossbeam are formed, and the present invention are made further specifying below in conjunction with accompanying drawing.

Fig. 1 is the three-dimensional view of embodiment supporting leg bracket component.

Fig. 2 is the three-dimensional view of the coaxial unsteady positioning tool embodiment in otic placode hole.

The corresponding part name of sequence number among the figure:

1. supporting leg bracket component otic placode 2. supporting leg bracket component base plates 3. welding benches

4. centering pole 5. guide pads 6. columns

7. crossbeam 8. active grabs 9. supporting leg bracket components float

The specific embodiment:

Fig. 1 is the three-dimensional view of embodiment supporting leg bracket component; By seeing among the figure; This embodiment assembly be a kind of engineering automobiles vehicle exclusive supporting leg groups of holders assembly 9, it is by two pairs, totally four supporting leg bracket component otic placodes 1 assemblings are welded on the supporting leg bracket component base plate 2 and form; Need keep axiality to the corresponding hole axial line of each piece otic placode, therefore need to adopt the method for the location of floating accurately to locate.

Fig. 2 is the three-dimensional view of the coaxial unsteady positioning tool embodiment in this novel otic placode hole; By seeing among the figure; These anchor clamps are by the basic fixed position platform of welding bench 3 as supporting leg bracket component 9; Four jiaos 6, two groups of unsteady crossbeam 7 skies of four root posts have been installed in the outside of supporting leg bracket component 9 and have been enclosed within the column 6, can easily move adjustment up and down along column 6.

Guide pad 5 is installed on the crossbeam 7 that floats; Guiding circular hole of its location usefulness can supply to feel relieved pole 4 inserts; So that the locating hole to supporting leg bracket component otic placode 1 positions; When not of uniform size the causing of profile of supporting leg bracket component otic placode, because therefore the 7 pairs of axial line control of position of crossbeam of floating can guarantee still that position, the hole axial line of respectively organizing supporting leg bracket component otic placode keeps axiality.

After accomplish the location, can fix the position of each assembly, just can implement then to weld with active grab 8.

Undoubtedly, more than be a concrete structure embodiment of the present invention, do not contain all other versions of the present invention, protection scope of the present invention also comprises the variation that other it will be apparent to those skilled in the art that naturally and substitutes.
