Description
Technical Field
The utility model relates to the technical field of laser welding fixtures, in particular to a floating compression block of a laser welding fixture.
Background
The laser welding process for automobiles is applied more and more frequently in the manufacturing process of body-in-white. The laser welding process is higher than resistance spot welding in welding strength; the laser welding speed is high, and tens of meters can be achieved per minute, so that the production beat is accelerated; the laser welding only needs single-side welding, so that the reserved welding edges are reduced, the overlapped plates are reduced, the quality of a vehicle body can be reduced, and the material cost is saved; therefore, the demand of the laser welding tool clamp is greatly increased, and an excellent clamp design concept is also favorable.
When the automobile is welded in a laser mode, gaps of lap surfaces of parts are uneven, the effect of a welding pool is affected, and welding-through welding defects are caused. In the actual automobile manufacturing process, the design of zero joint is difficult to realize on the lap joint surface between the parts; gaps often exist in lap joints of parts, and welding seams at large gaps cannot meet laser welding conditions.
Disclosure of Invention
To the not enough of above-mentioned prior art, the technical problem that this patent application will solve provides how to improve and compresses tightly effect, simple structure, and convenient to use's laser welding anchor clamps compress tightly the piece that floats.
In order to solve the technical problems, the utility model adopts the following technical scheme:
a floating pressing block of a laser welding clamp comprises a mounting seat, a pin baffle, a floating pressing block, a inch sleeve and a central shaft pin;
the mounting seat is provided with a floating notch; the briquetting that floats is the U-shaped, the briquetting that floats have connecting portion and with connecting portion fixed connection's two portions that compress tightly, connecting portion set up in the notch that floats and can float, connecting portion have the centre bore, cun cover fixed mounting in the centre bore, the both sides that the mount pad corresponds the notch that floats are provided with the mounting hole, the centre pivot overlaps normal running fit and both ends with cun and is located in the mounting hole, the dog-ear just to the mounting hole and with the outer end fixed connection of mount pad and centre pivot.
Wherein, the interval 1mm sets up between the roof of the connecting portion of unsteady briquetting and the unsteady notch of mount pad.
The pin baffle plate is fixedly connected with the mounting seat through two bolts.
The pressing part of the floating pressing block is obliquely arranged downwards, and the lower end of the pressing part is provided with a pressing surface.
Wherein, the floating pressing block is integrally formed.
In conclusion, the utility model has the advantages of improved compression effect, simple structure and convenient use.
Drawings
Fig. 1 is a schematic structural diagram of a floating pressing block of a laser welding fixture according to the present invention.
Fig. 2 is a schematic view of the mount of fig. 1.
FIG. 3 is a schematic view of the floating compact of FIG. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings. In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
As shown in fig. 1-3, a floating pressing block of a laser welding fixture comprises a mounting seat 1, a pin baffle 2, a floating pressing block, a cun sleeve and a central shaft pin;
the mounting seat is provided with a floating notch 3; the briquetting that floats is the U-shaped, the briquetting that floats have connecting portion 4 and with connecting portion fixed connection's two portions of compressing tightly 5, connecting portion set up in the notch that floats and can float, connecting portion have centre bore 7, cun cover fixed mounting be in the centre bore, the both sides that the mount pad corresponds the notch that floats are provided with mounting hole 8, the centre pivot overlaps normal running fit and both ends with cun and is located in the mounting hole, the dog-catch plate just to the mounting hole and with the outer end fixed connection of mount pad and centre pivot.
Like this, when compressing tightly, the briquetting that floats can rotate around central pivot and realize the unsteady of briquetting that floats promptly, even there is the difference in height in two pressure points, anchor clamps compress tightly the back and still can guarantee that welding seam department faying surface clearance is close to the laminating, can obtain the qualified laser welding seam of quality. Be provided with the backing pin board, avoid the central pivot roll-off, the holistic assembly of being convenient for simultaneously.
The distance between the connecting part of the floating pressing block and the top wall of the floating notch of the mounting seat is 1mm, and the gap is 6 marked in the figure. The floating press block rotates around the central shaft pin, so that the two pressing parts have height difference, the workpiece is better pressed, and the lap joint gap at the welding seam is nearly attached.
The pin baffle plate is fixedly connected with the mounting seat through two bolts.
The pressing part of the floating pressing block is obliquely arranged downwards, and the lower end of the pressing part is provided with a pressing surface.
Wherein, the floating pressing block is integrally formed.
Specifically, the cun sleeve adopts a 'double-flying' brand standard part, model SF-11215; the central shaft PIN adopts a 'MISUMI' brand standard part, and the model number is PIN-12x 30; the pin baffle is in a mechanical nonstandard design, and two M6 bolts are adopted for external locking and fixing; the central shaft pin is mainly used for blocking the central shaft pin and preventing the central shaft pin from falling off in the using process; floating press blocks, wherein the mechanical nonstandard design is adopted, and the lengths and the sizes of two press points are designed according to the length of a laser welding seam; and a cun sleeve is arranged on the central hole; the mounting seat is in a mechanical nonstandard design and is used for mounting the floating pressing block, the central shaft pin and the pin baffle.
During assembly, the cun sleeve is pressed into a central hole of the floating pressing block, the floating pressing block is connected with the mounting seat through the central shaft pin, and finally the pin blocking plate is fixed on the mounting seat and the central shaft pin through the bolt.
Finally, it should be noted that: various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
