[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0028] Please refer to Figures 1 to 3A welding stripping jig includes a base 1, a pressing block 2 and a stripping slider 3. The pressing block 2 is detachably connected to the base 1, and the stripping slider 3 is installed on the base 1. The stripping slider 3 is arranged on the side of the pressing block 2. The stripping slider 3 can slide relative to the base 1 to approach or move away from the pressing block 2. A first product avoidance groove 31 is provided at the bottom of the stripping slider 3 on the side close to the pressing block 2.

[0029] As can be seen from the above description, the beneficial effect of the present invention is that the pressing block 2 in the present welding stripping jig is used to clamp the steel sheet 8 carrying multiple products 7. The stripping slider 3 slides toward the pressing block 2 to simultaneously squeeze the multiple products 7 on the steel sheet 8, causing the multiple products 7 to rotate relative to the steel sheet 8, thereby breaking the connection between the multiple products 7 and the steel sheet 8 at one time, and efficiently stripping the products 7 from the steel sheet 8. The first product clearance groove 31 is used to avoid the product 7 being bent relative to the steel sheet 8.

[0030] Furthermore, a plurality of protruding pressing portions 21 are provided on one side of the pressing block 2 close to the stripping slider 3 , and a stripping groove 22 is formed between any two of the pressing portions 21 . An extrusion boss 32 is provided on one side of the stripping slider 3 close to the pressing block 2 corresponding to the stripping groove 22 .

[0031] From the above description, it can be seen that the pressing part 21 is used to press the steel sheet 8 that supports the product 7, and the stripping groove 22 can increase the moving stroke of the extrusion boss 32, so that the stripping slider 3 can drive the product 7 to bend relative to the steel sheet 8 to a greater extent to ensure that the product 7 falls off completely.

[0032] Furthermore, a sliding groove 11 and a matching boss 33 matching with the sliding groove 11 are respectively provided on the base 1 and the stripping slider 3.

[0033] As can be seen from the above description, the connection method between the base 1 and the stripping slider 3 is simple and easy to assemble.

[0034] Furthermore, one end of the chute 11 is connected to the base 1 or a side of the stripping slider 3 away from the pressing block 2 .

[0035] It can be seen from the above description that one end of the chute 11 is connected to the side of the base 1 or the stripping slider 3, which can facilitate the processing and molding of the chute 11 and the fitting of the boss 33 into the chute 11.

[0036] Furthermore, a detachable limiting member 4 is provided on the inner side of one end of the slide groove 11 away from the pressing block 2 .

[0037] As can be seen from the above description, the limiting member 4 is used to prevent the stripping slider 3 from accidentally separating from the base 1 during use.

[0038] Furthermore, the limiting member 4 is connected to the base 1 via threads.

[0039] It can be seen from the above description that the connection method between the limiting member 4 and the base 1 is simple and easy to assemble and disassemble.

[0040] Furthermore, the pressing block 2 and the base 1 are respectively provided with a positioning pin 5 and a positioning hole 23 plugged into and matched with the positioning pin 5 .

[0041] As can be seen from the above description, the insertion of the positioning pin 5 into the positioning hole 23 can limit the relative position of the pressing block 2 and the base 1, thereby improving the assembly accuracy.

[0042] Furthermore, at least one product limiting pin 6 is provided on the base 1 .

[0043] As can be seen from the above description, the product limiting pin 6 is used to limit the position of the steel sheet 8 and the product 7, so that the pressing block 2 can be accurately pressed against the steel sheet 8.

[0044] Furthermore, the pressing block 2 is connected to the base 1 via screws.

[0045] As can be seen from the above description, the connection method between the pressing block 2 and the base 1 is simple and easy to assemble and disassemble.

[0046] Furthermore, a second product avoiding groove 12 is provided on the base 1 .

[0047] As can be seen from the above description, the second product avoidance groove 12 is used to avoid the product 7 protruding from the bottom area of ​​the steel sheet 8, so that the steel sheet 8 can be placed flat on the base 1 to facilitate the pressing of the pressing block 2.

[0048] Please refer to Figures 1 to 3 , Embodiment 1 of the present invention is: a welding stripping jig for stripping a plurality of products 7 welded to a steel sheet 8 by a spot welding process.

[0049] The welding stripping jig includes a base 1, a pressing block 2 and a stripping slider 3. The pressing block 2 is detachably connected to the base 1, and the stripping slider 3 is installed on the base 1. The stripping slider 3 is arranged on the side of the pressing block 2. The stripping slider 3 can slide relative to the base 1 to approach or move away from the pressing block 2. A first product air avoidance groove 31 is provided at the bottom of the stripping slider 3 on the side close to the pressing block 2.

[0050] Specifically, the base 1 is rectangular in shape, with the pressing block 2 attached to the top of the base 1 via screws. A clamping area is formed between the pressing block 2 and the top surface of the base 1 for holding the steel sheet 8 carrying the product 7. A retaining groove 13 is also provided on the top surface of the base 1. This groove 13 is located on the side of the pressing block 2 closest to the stripping slider 3 and extends parallel to the side of the pressing block 2 closest to the stripping slider 3. The shape of the retaining groove 13 matches the shape of the steel sheet 8, and its depth is less than the thickness of the steel sheet 8. The bottom of the steel sheet 8 carrying the product 7 is located within the retaining groove 13. As will be readily understood, the retaining groove 13 prevents the pressing block 2 from over-compressing the steel sheet 8, potentially damaging it or the pressing block 2. When the stripping slider 3 slides toward the pressing block 2, it simultaneously compresses multiple products 7 on the steel sheet 8, causing them to rotate relative to the steel sheet 8. This, in turn, breaks the connections between multiple products 7 and the steel sheet 8 at once, effectively stripping the products 7 from the steel sheet 8. The first product avoiding groove 31 is used to avoid the product 7 that is bent relative to the steel sheet 8.

[0051] The pressing block 2 is provided with a plurality of protruding pressing portions 21 on one side close to the stripping slider 3, and a stripping groove 22 is formed between any two pressing portions 21. The stripping slider 3 is provided with an extrusion boss 32 on one side close to the pressing block 2 corresponding to the stripping groove 22. It is easy to understand that the pressing portion 21 is used to press the steel sheet 8 carrying the product 7, and the stripping groove 22 can increase the moving stroke of the extrusion boss 32, so that the stripping slider 3 can drive the product 7 to bend relative to the steel sheet 8 to a greater extent to ensure that the product 7 is completely removed.

[0052] The base 1 and the stripping slider 3 are respectively provided with a chute 11 and a mating boss 33 that cooperates with the chute 11. Specifically, the chute 11 is provided on the base 1 and is connected to the top surface of the base 1. The cross-section of the chute 11 is in an inverted T-shape, and the extension direction of the chute 11 is perpendicular to the side of the pressure block 2 close to the stripping slider 3. The mating boss 33 is provided on the stripping slider 3. The cross-sectional shape of the mating boss 33 is adapted to the cross-sectional shape of the chute 11. The mating boss 33 and the stripping slider 3 are an integrally formed, one-piece structure. In other embodiments, it is also feasible to provide the chute 11 on the stripping slider 3 and the mating boss 33 on the base 1.

[0053] In order to facilitate the processing and forming of the chute 11 , one end of the chute 11 is connected to the base 1 or the side of the stripping slider 3 away from the pressing block 2 .

[0054] In order to limit the mating boss 33 in the chute 11 and prevent the stripping slider 3 from accidentally detaching from the base 1 during use, a detachable limiter 4 is provided on the inner side of the end of the chute 11 away from the pressing block 2. Specifically, the limiter 4 is a screw, and the limiter 4 is connected to the base 1 through a threaded connection.

[0055] The pressure block 2 and the base 1 are each provided with a positioning pin 5 and a positioning hole 23 for plugging into the positioning pin 5. Specifically, there are two cylindrical positioning pins 5 provided on the base 1. The positioning holes 23 correspond to the number of positioning pins 5, with one positioning hole 23 being circular and the other being oblong.

[0056] At least one product stop pin 6 is provided on the base 1. Specifically, the product stop pin 6 is used to cooperate with a stop hole in a steel sheet 8 supporting the product 7, thereby limiting the position of the steel sheet 8 or the product 7, so that the pressing block 2 can accurately press the steel sheet 8. There are two product stop pins 6, each cylindrical in shape, with the top end of the product stop pin 6 protruding from the bottom surface of the stop slot 13, and the edge of the top end of the product stop pin 6 is set at an oblique angle.

[0057] The base 1 is provided with a second product clearance groove 12 for the product 7. Specifically, the second product clearance groove 12 is a through groove extending parallel to the side of the pressing block 2 near the stripping slide 3. The second product clearance groove 12 is provided on the side of the limiting groove 13 near the stripping slide 3. The second product clearance groove 12 is used to prevent the product 7 from protruding from the bottom surface of the steel sheet 8, allowing the steel sheet 8 to lie flat on the base 1 and be pressed by the pressing block 2.

[0058] In summary, the pressure block in the welding stripping fixture provided by the present invention is used to clamp a steel sheet carrying multiple products. The stripping slider slides toward the pressure block, simultaneously squeezing the multiple products on the steel sheet, causing them to rotate relative to the sheet. This simultaneously breaks the connections between the multiple products and the sheet, efficiently stripping the products from the sheet. The first product clearance groove is used to avoid products that have been bent relative to the sheet.
