[0028] Laser welding is a commonly used method in product forming technology. Before laser welding, the parts to be welded of the workpieces to be welded need to be accurately positioned and docked to ensure that the welded products can have higher precision. Before laser welding, the two surfaces to be welded need to be pressed and fitted. When the shapes of the two workpieces to be welded are more complex, it is often difficult to accurately position the two parts to be welded during the pressing and positioning, resulting in a higher scrap rate of the workpieces after welding.

[0029] In order to solve the above problems, the utility model proposes a flip welding tool, which aims to improve the positioning and pressing accuracy of the parts to be welded and improve the yield rate of laser welding. Figures 1 to 4 The present invention is a schematic structural diagram of an embodiment of the flip welding tool provided by the present invention.

[0030] Please refer to Figures 1 to 4The utility model proposes a flip welding tool 1000, including a base 1 and an upper cover 2, wherein the base 1 is formed with a mounting groove 11 for mounting and fixing a first workpiece 100 to be welded; the upper cover 2 is provided with a fixing assembly 21 for mounting and fixing a second workpiece 200 to be welded, one end of the upper cover 2 is connected to one end of the base 1 by a hinge, the upper cover 2 can be flipped relative to the base 1 along the hinge to realize the opening and closing of the flip welding tool 1000, and the upper cover 2 is formed with an avoidance hole 22 corresponding to the welding position of the workpiece to be welded.

[0031] In the technical solution of the utility model, a flip welding tool 1000 is proposed, including a base 1 and an upper cover 2, the base 1 is provided with a mounting groove 11 for mounting a first workpiece to be welded 100, the upper cover 2 is provided with a fixing assembly 21 for fixing a second workpiece to be welded 200, and the upper cover 2 is rotated along the base 1 through a hinge structure to realize the opening and closing of the flip welding tool 1000, thereby realizing the positioning of the first workpiece to be welded 100 and the second workpiece to be welded 200, and the avoidance hole 22 makes it easy for the welding head to be inserted to weld the first workpiece to be welded 100 and the second welding workpiece, thereby improving the stability of welding.

[0032] In an optional embodiment, in order to facilitate the fixing of the second workpiece 200 to be welded on the upper cover 2, the fixing assembly 21 includes a fixed stopper 211 and an elastic abutment 212, wherein the fixed stopper 211 is respectively convexly arranged on the first side and the second side adjacent to the avoidance hole 22, and the elastic abutment 212 is arranged on the outer edge of the avoidance hole 22. Figures 2 to 4 Two fixed blocks 211 are respectively provided on the upper cover 2, and the two fixed blocks 211 are respectively located at the first side of the avoidance hole 22 and the second side adjacent to the first side, so that the two adjacent sides of the second workpiece 200 to be welded are respectively abutted against the two fixed blocks 211, which is convenient for positioning and fixing the second welding workpiece, and then the other two side edges of the second workpiece 200 to be welded are abutted by the elastic abutting member 212, so that the second workpiece 200 to be welded is accurately positioned and fixed on the upper cover 2, which is convenient for the upper cover 2 to be flipped so that the second workpiece 200 to be welded is accurately matched and positioned with the first workpiece 100 to be welded to improve the welding yield rate.

[0033] Specifically, in order to realize the elastic fixation of the second workpiece 200 to be welded, the elastic abutting member 212 includes a spring 2121 and a abutting member 2122, wherein the abutting member 2122 is connected to one end of the spring 2121, and the abutting member 2122 is used to abut the second workpiece 200 to be welded. Figure 4In order to facilitate the fixed limitation of the spring 2121 and the push piece 2122 and to achieve the fixing effect of the second workpiece 200 to be welded, a receiving groove with a protrusion can be opened in the upper cover 2, by horizontally arranging the spring 2121 in the receiving groove, and by sleeved one end of the spring 2121 on the protrusion so that the spring 2121 can be compressed and deformed relative to the protrusion by force, and by clamping the push piece 2122 on the other end of the spring 2121, the push piece 2122 can be horizontally moved relative to the upper cover 2 under the elastic force of the spring 2121, thereby realizing elastic fixation of the second workpiece 200 to be welded. Furthermore, in order to prevent the spring 2121 from longitudinally offsetting the receiving groove relative to the receiving groove during the elastic deformation, a cover plate can be arranged above the receiving groove to limit the longitudinal displacement of the spring 2121 and ensure the normal operation of the elastic push piece 212.

[0034] Furthermore, in order to elastically fix the second workpiece to be welded with different sides, the abutting member 2122 includes a clamping block and a clamping roller. In the actual welding production process, the second workpiece to be welded 200 is generally not a plate-like structure with a regular shape and uniform thickness, but more often it is uneven in thickness or has a bent structure formed at the edge. In order to fix the second workpiece to be welded 200 with uneven thickness on each side, please refer to Figures 2 to 4 The abutting member 2122 can be a clamping block or a clamping roller. When the side of the second workpiece 200 to be welded is thinner, it can be directly abutted and fixed by the clamping block. When some sides of the second workpiece 200 to be welded are provided with a bending structure, the height of the second workpiece 200 to be welded is relatively high. When the clamping block is directly used for abutment, the height of the clamping block may not be enough. At this time, the bent edge of the second workpiece 200 to be welded can be abutted and fixed by the roller. Because the roller is in a rollable state, the bent edge of the second workpiece 200 to be welded will not be easily deformed when abutting against it, which is beneficial to the stability of the second workpiece 200 to be welded.

[0035] In an optional embodiment, in order to facilitate the fixing of the first workpiece 100 to be welded in the mounting groove 11, a suction head 12 is provided at the bottom of the mounting groove 11, and the suction head 12 is connected to the suction pipe for adsorbing and fixing the first workpiece 100 to be welded. Figure 3The adsorption head 12 is arranged at the bottom of the installation groove 11, and the adsorption head 12 is correspondingly connected with a suction pipe to generate suction to the adsorption head 12. When the first workpiece 100 to be welded is placed in the installation groove 11, the adsorption head 12 is close to the bottom of the first workpiece 100 to be welded and forms a negative pressure to suck the first workpiece 100 to be welded so that it is fixed in the installation groove 11, thereby preventing the first workpiece 100 to be welded from moving in the installation groove 11. Optionally, the number of the adsorption heads 12 can be two, three or more, which can be selected according to the volume and weight of the first workpiece 100 to be welded, and is not specifically limited here. In addition, in order to facilitate the precise positioning of the first workpiece 100 to be welded in the installation groove 11, a positioning column or a positioning hole can be set in the installation groove 11 to cooperate with the first workpiece 100 to be welded. In this way, it is only necessary to match and fix the first workpiece 100 to be welded with the positioning column or the positioning hole in the installation groove 11, which can ensure that the first workpiece 100 to be welded is precisely positioned in the base 1, and facilitate the flip welding tool 1000 to make the first workpiece 100 to be welded and the second workpiece 200 to be welded accurately match when the mold is closed, thereby ensuring the accuracy of the welded product.

[0036] In an optional embodiment, in order to achieve the precision of the mold joining between the upper cover 2 and the base 1, the upper cover 2 is provided with a positioning pin 23, and the base 1 is provided with a positioning groove 13 corresponding to the positioning pin 23, and one positioning pin 23 and one positioning groove 13 are correspondingly matched for positioning. Figures 2 to 4 Four positioning pins 23 are respectively provided around the upper cover 2, and four positioning grooves 13 are correspondingly provided around the base 1. When the upper cover 2 is flipped over and molded with the base 1, one positioning pin 23 is fixedly matched with one positioning groove 13 to ensure the accuracy of the mold, thereby ensuring the matching accuracy of the first workpiece 100 to be welded and the second workpiece 200 to be welded.

[0037] Furthermore, in order to maintain the fixing effect of the positioning pin 23 and the positioning groove 13 after the flip welding fixture 1000 is molded, the flip welding fixture 1000 also includes a locking member, which is arranged on the base 1 and is movably connected to the positioning pin 23 to fix the positioning pin 23 to the positioning groove 13. The locking member applies a force to the positioning pin 23 so that it is firmly connected to the fixing groove, thereby ensuring the stability of the flip welding fixture 1000 after the mold is closed, and facilitating the welding of the first workpiece 100 to be welded and the second workpiece 200 to be welded.

[0038] In an optional embodiment, the locking member is a locking cylinder 3, and the output end of the locking cylinder 3 is penetrated through the groove wall of the positioning groove 13 and abuts against the positioning pin 23. Figures 1 to 3The locking cylinders 3 are respectively arranged on the side walls of the base 1 corresponding to the positioning grooves 13, and through holes are opened on the side walls of the base 1, so that the output ends of the locking cylinders 3 can extend into the positioning grooves 13 through the through holes to resist the positioning pins 23. In this way, after the flip welding tooling 1000 is molded, each locking cylinder 3 is driven to lock each positioning pin 23 in each positioning groove 13, thereby ensuring the stability of the flip welding tooling 1000 when the mold is closed.

[0039] In another optional embodiment, the locking member is a magnetic attraction structure, and the magnetic attraction structure includes a first magnetic attraction part and a second magnetic attraction part, wherein the first magnetic attraction part and the second magnetic attraction part are arranged at the bottom of the positioning groove 13 and the positioning pin 23, and the first magnetic attraction part and the second magnetic attraction part are magnetically matched. Optionally, the positioning pin 23 and the positioning groove 13 can be fixed by utilizing the magnetic attraction effect, for example, by respectively arranging the first magnetic attraction part and the second magnetic attraction part in the positioning groove 13 and the positioning pin 23, and the first magnetic attraction part and the second magnetic attraction part generate mutual attraction to fix the positioning pin 23 and the positioning groove 13, and optionally, the first magnetic attraction part and the second magnetic attraction part can be magnets with their own magnetic force, or can be electromagnets, and the first magnetic attraction part and the second magnetic attraction part are energized after the positioning pin 23 and the positioning groove 13 are molded and matched to make the two magnetically matched, and the specific selection can be made according to actual needs, and no specific limitation is made here.

[0040] In an optional embodiment, in order to pressurize and fix the flip welding fixture 1000 after mold closing, the flip welding fixture 1000 further includes a lifting and pressurizing cylinder 4, which is arranged below the base 1, and the output end of the lifting and pressurizing cylinder 4 abuts against the base 1. Please refer to Figures 1 to 3 A lifting and pressurizing cylinder 4 is respectively provided at the two ends below the base 1, and the output of the lifting and pressurizing cylinder 4 presses against the base 1. After the flip welding fixture 1000 is molded, an upward pressure is applied to the base 1 to further increase the mold closing pressure of the flip welding fixture 1000, so as to further ensure the matching effect of the first workpiece 100 to be welded and the second workpiece 200 to be welded.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
