[0002] Stamping is a forming process in which a press and a die apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping) of the desired shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips.

[0003] During the processing of stamping parts on the automobile body, welding is required, and welding equipment is usually used for the operation.

[0004] In the prior art, the stamped parts of automobile accessories need to be positioned before welding, and the positioning tooling in the prior art usually uses springs and clamps, multiple clamps move downward or two clamps move toward each other, and the automobile stamped parts are fixed by the force of the spring. Only the force of the spring cannot achieve a good positioning effect. If hard contact is directly used, when the stamped parts are fixed, some thinner stamped parts on some cars may be deformed due to pressure, affecting the welding work. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] refer to Figure 1-Figure 4 , an automobile stamping parts welding equipment, comprising:

[0030] A welding platform 100, wherein a base 101 is provided at the bottom of the welding platform 100, and a plurality of top openings 102 are provided at the top of the welding platform 100;

[0031] A connecting pipe 103 is provided between the welding platform 100 and the base 101;

[0032] A slide bar 104 is disposed in the top opening 102, a parallel clamping plate 105 is disposed on one side of the slide bar 104, a vertical clamping plate 106 is disposed on the top of the parallel clamping plate 105, and a preset distance is provided between the vertical clamping plate 106 and the parallel clamping plate 105;

[0033] The moving component is disposed between the connecting tube 103 and the slide bar 104 and is used to move the position of the slide bar 104. The slide bar 104 moves toward the central axis of the connecting tube 103, and the slide bars 104 in the top openings 102 move synchronously.

[0034] A positioning component is disposed between the parallel clamping plate 105 and the vertical clamping plate 106, and is used to move the position of the vertical clamping plate 106 when the parallel clamping plate 105 moves relative to the slide bar 104, and the vertical clamping plate 106 moves toward the welding platform 100;

[0035] By setting up the welding platform 100, the operator can place the automobile stamping parts that need to be welded on the welding platform 100, and appropriately adjust the position of the workpiece so that the workpiece is between the multiple slide bars 104. When in use, the operator can use the moving component to move the position of the slide bar 104 so that the slide bar 104 moves toward the central axis of the connecting pipe 103. The multiple slide bars 104 move synchronously, which can allow the parallel clamping plates 105 on the slide bar 104 to move toward the workpiece and release the workpiece. The position of the slide bar 104 can be continued to be moved so that the parallel clamping plates 105 move relative to the slide bar 104. During the movement, the positioning component set can move vertically downward. The position of the straight clamp 106, the vertical clamp 106 moves toward the workpiece until the vertical clamp 106 releases the workpiece, so that the parallel clamps 105 on the multiple slides can be used to position the four sides of the workpiece, and then the vertical clamp 106 can be used to position the top of the workpiece. While avoiding applying a large clamping force to the workpiece, the stability of the workpiece fixation is guaranteed, which solves the problem of using the force of the spring to fix the automobile stamping parts in the prior art. Only using the force of the spring cannot achieve a good positioning effect. If hard contact is used directly, it will cause the problem of deformation due to pressure for some thinner stamping parts on some cars when the stamping parts are fixed.

[0036] As a further feature of the present invention, the positioning member includes a rack 200 connected to one side of the parallel clamping plate 105, the rack 200 is slidably connected to the slide bar 104, one side of the slide bar 104 is rotatably connected to a screw rod 201 threadedly connected to the vertical clamping plate 106, and the screw rod 201 is provided with a gear 202 meshing with the rack 200;

[0037] By setting the rack 200, when the parallel clamping plate 105 moves relative to the slide rod 104, the set rack 200 can drive the gear 202 and the screw rod 201 to rotate. The rotation of the screw rod 201 can use the force of the thread to move the position of the vertical clamping plate 106 downward, thereby achieving the purpose of fixing the surroundings and the top of the workpiece.

[0038] As a further feature of the present invention, an elastic member 203 is connected between the parallel clamping plate 105 and the slide bar 104;

[0039] By setting the elastic member 203, the elastic member 203 can give the parallel clamping plate 105 a certain force to release the workpiece, and at the same time, after the slide bar 104 is reset, the vertical clamping plate 106 can be reset upward, which is convenient for positioning the workpiece next time. At the same time, it also ensures that when the slide bar 104 is moved, the parallel clamping plate 105 will not excessively squeeze the workpiece and cause deformation of the workpiece.

[0040] As a further feature of the present invention, a ring body 204 is provided on the outside of the screw rod 201, and a plurality of spring rods 205 are provided on the ring body 204, one end of the spring rod 205 is semi-spherical, and a plurality of slots 206 adapted to the spring rods 205 are provided on the inner side wall of the gear 202;

[0041] By setting the spring rod 205, after the spring rod 205 and the slot 206 are sleeved, the friction between the spring rod 205 and the slot 206 can be used to rotate the screw rod 201 when the gear 202 rotates. After the parallel clamping plate 105 moves to the preset position so that the vertical clamping plate 106 moves downward to contact the workpiece, the movement of the vertical clamping plate 106 is restricted. If the slide bar 104 continues to move, the spring rod 205 is forced to shrink and disengage from the slot 206, that is, the gear 202 idles outside the screw rod 201, avoiding the problem of excessive squeezing of the workpiece by the vertical clamping plate 106 due to excessive movement of the slide bar 104.

[0042] As a further feature of the present invention, the moving component includes a slider 300 slidably connected to the connecting tube 103, the outer wall of the slider 300 is rotatably connected to a plurality of first rods 301, one end of the first rod 301 is slidably connected to a second rod 302, the outer wall of the connecting tube 103 is connected to a bracket 303 rotatably connected to the second rod 302, and the second rod 302 is slidably connected to the slide bar 104;

[0043] By setting the slider 300, during application, the operator can move the position of the slider 300 upward or downward. The movement of the slider 300 can allow the second rod 302 to rotate with the bracket 303 as the rotation center through the first rod 301. The second rod 302 can pull the position of the slide bar 104, thereby achieving the purpose of moving the slide bar 104.

[0044] As a further feature of the present invention, the bottom of the connecting tube 103 is connected to an electric push rod 304, and the telescopic shaft of the electric push rod 304 is connected to the slider 300;

[0045] By providing the electric push rod 304, when in use, the purpose of moving the slide plate up and down can be achieved by utilizing the telescopic shaft movement of the electric push rod 304.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
