Abstract

The utility model discloses a fixture used for automobile body outer board spot welding, which comprises a clamping mechanism, wherein a plurality of insulation seats are fixed on the clamping mechanism, a plurality of vertical fixing holes are arranged on the insulation seats, screws and electrodes are respectively arranged below and above each fixing hole, the lower ends of the electrodes are inserted into the fixing holes, and the head parts of the screws are inserted into the fixing holes and are connected with the lower ends of the electrodes by threads, so that the electrodes are fixed on the insulation seats. As the plurality of fixing holes for fixing the electrodes are arranged on the insulation seats, an operator can change the positions of the electrodes according to needs; in addition, the diameter of the electrodes can be set larger than the diameter of electrodes of an electrode holder so as to improve the quality of welding spots.

Description

Anchor clamps are used in the spot welding of body of a motor car outside plate
Technical field
The utility model relates to a kind of anchor clamps, relates in particular to the spot welding of a kind of body of a motor car outside plate and uses anchor clamps.
Background technology
Some is distributed on the vehicle body outside surface part solder joint on the interior of body part except being distributed on the body of a motor car, and the quality of automobile body external panel quality directly influences the spraying and the whole outer surface quality of automobile of automotive paints.The solder joint of body of a motor car 90% all is the mash welder welding, and the welding that comprises outer surface generally also is a spot-welded on.The vehicle body outside surface welding requirements is very high so be welded, and is the key that influences the direct outward appearance of automobile.
Common mash welder power-on and power-off cartridge all is tapered, and acting surface has only 5-7mm, and the solder joint surface is not smooth after welding, and the vehicle body outside surface required precision is very high, thus after the welding to reprocess difficulty very big, surface quality is difficult to guarantee.The solder joint of the station in workshop of being welded generally has about 40, and the vehicle body outside surface solder joint can not remove the frequent change electrode at about 2 the solder joint just of the distribution on the station because of 2 solder joints owing to work continuously.
Summary of the invention
The utility model provides the spot welding of a kind of body of a motor car outside plate to use anchor clamps, utilizes these anchor clamps to cooperate soldering turret to use, and can let solder joint smooth, and not need the frequent change electrode.
Anchor clamps are used in the spot welding of a kind of body of a motor car outside plate; Comprise clamping device; Be fixed with some insulating bases on the said clamping device, said insulating base is provided with the fixing hole of plurality of vertical, and the below of one of them fixing hole and top are respectively equipped with the electrode of screw and bottom insertion fixing hole; Screw head inserts fixing hole and is threaded with the electrode bottom, and electrode is fixed on the insulating base.
Preferably, said electrode periphery is provided with the bulge loop of external diameter greater than the fixing hole internal diameter.
Said insulating base is the square plate formula structure of band unfilled corner, and the unfilled corner both sides are respectively equipped with fixing hole and screwed hole relatively, and the unfilled corner edge extends to form guide plate downwards.
Said insulating base top is provided with additional seat, and additional seat part is positioned at the unfilled corner top, and this part is provided with a fixing hole, and insulating base is close in the remainder bottom surface, is fixed on the insulating base.
Insulating base on the utility model anchor clamps is provided with the fixing hole of a plurality of fixed electrodes, and the operator is the conversion electrode position as required, and the diameter of electrode can be arranged to greatlyyer than soldering turret electrode diameter in addition, can improve quality of welding spot.
Description of drawings
Fig. 1 is the structural representation of the utility model anchor clamps;
The structural representation of Fig. 2 the utility model insulating base;
Fig. 3 is the structural representation of the utility model screw and electrode;
Fig. 4 adds the structural representation behind seat and the electrode for the utility model insulating base assembles.
The specific embodiment
As shown in Figure 1; Anchor clamps are used in the spot welding of a kind of body of a motor car outside plate, comprise clamping device 1 and insulating base 2, and clamping device 1 is made up of base 101, cylinder 102 and clamp arm 103; Cylinder 102 stretches and just can realize the clamping workpiece, and the quantity of insulating base 2 can be according to setting.
Insulating base 2 main bodys are the plate armature of band unfilled corner 201, and the both sides of unfilled corner 201 are respectively equipped with two fixing holes 202 and screwed hole 203 relatively, and unfilled corner 201 edges extend to form guide plate 204 downwards.One of them fixing hole above and below is respectively equipped with electrode 3 and screw 4; Fixing hole is stretched in electrode 3 bottoms, and screw 4 heads stretch into fixing hole and are threaded with electrode 3 bottoms, drops in order to prevent electrode 3; Electrode 3 peripheries are provided with bulge loop 301, and the external diameter of bulge loop 301 is greater than the internal diameter of fixing hole.
Above insulating base 2, also be provided with additional seat 5; Attachment base 5 parts are positioned at unfilled corner 201 tops; And this part is provided with the fixing hole of electrode, and remainder and insulating base 2 are close to and are provided with locating hole, and bolt passes locating hole and screwed hole 203 is fixed on it on the insulating base 2.
During use, utilize clamping device 1 that vehicle-body outer panel is clamped, electrode 3 alignings need the place of spot welding; The bottom electrode of soldering turret contacts with the screw 4 of electrode 3 belows, and top electrode contacts with the upper surface of outside plate, accomplishes spot welding; When needs change bond pad locations; Can electrode 3 and screw 4 be disassembled, be installed in the other fixing hole, easy to operate.In pinpoint welding procedure, guide plate 204 is mainly used in the location of soldering turret, prevents skew, and the diameter of electrode 3 is bigger in addition, can guarantee that solder joint is smooth.
