[0022] The left block 2 , the contour block 3 and the right block 4 are all fixed on the upper surface of the base plate 1 and are spaced apart from left to right.

[0023] Two first positioning pins 8 for respectively engaging with two first connection holes N-11 on the first angle plate N-1 are fixedly provided on the upper surface of the left block 2. The first pressing device 5 is used to press the first angle plate N-1.

[0024] Preferably, the first pressing device 5 is a rotary cylinder.

[0025] See Figure 5-8 During clamping, the first angle plate N-1 is placed on the left block 2, with the inner surface of one side of the first angle plate N-1 in contact with the upper surface of the left block 2, and the inner surface of the other side of the first angle plate N-1 in contact with the right side of the left block 2; and the two first positioning pins 8 are respectively inserted into the two first connecting holes N-11 of the first angle plate N-1, and then the first angle plate N-1 can be pressed by the first clamping device 5, thereby achieving precise positioning and clamping of the first angle plate N-1.

[0026] See Figure 3-4 , wherein the right block 4 is provided with a pointed top 4-1 for cooperating with the second angle plate N-2; two second positioning pins 9 are fixedly provided on the pointed top 4-1 for respectively cooperating with the two second connecting holes N-21 on the second angle plate N-2; the third clamping device 7 is used to clamp the second angle plate N-3.

[0027] Preferably, the third pressing device 7 is a rotary cylinder.

[0028] See Figure 5-8 During clamping, the second angle plate N-2 is placed on the pointed top portion 4-1 for alignment. Specifically, the inner surfaces of both sides of the second angle plate N-2 are aligned with the two inclined surfaces of the pointed top portion 4-1, and the two second positioning pins 9 are respectively inserted into the two second connection holes N-21 of the second angle plate N-2. The second angle plate N-2 is then pressed by the third pressing device 7, thereby achieving precise positioning and compression of the second angle plate N-2.

[0029] See Figure 3-4, wherein the profiling block 3 is provided with two profiling grooves 3-1 for inserting two elbows N-3 respectively; and the second pressing device 6 is used to press the two elbows N-3 at the same time.

[0030] See Figure 5-8 During clamping, the two elbows N-3 are respectively inserted into the two profiling grooves 3-1 on the profiling block 3 to be positioned, and at the same time, both ends of the two elbows N-3 are respectively in contact with the first angle plate N-1 and the second angle plate N-2; then, the middle parts of the two elbows N-3 can be simultaneously pressed by the second pressing device 6, thereby achieving accurate positioning and pressing of the two elbows N-3;

[0031] See Figure 3-4 In this embodiment, the second clamping device 6 includes a strip pressure plate 6-1, a screw 6-2 and a nut 6-3; the lower end of the screw 6-2 is fixed to the profiling block 3 and is located between the two profiling grooves 3-1, and a U-shaped groove 6-11 is provided on the strip pressure plate 6-1; the screw 6-2 passes upward through the U-shaped groove 6-11 and is connected with the nut 6-3, and the strip pressure plate 6-1 will simultaneously press the middle parts of the two elbows N-3.

[0032] When the second pressing device 6 is pressed, the strip pressing plate 6-1 presses on the two elbows N-3, and the screw 6-2 passes upward through the U-shaped groove 6-11 and is connected to the nut 6-3; and the nut 6-3 is rotated and tightened downward. At this time, the strip pressing plate 6-1 presses on the two elbows N-3 (see Figure 7-8 ). When the second pressing device 6 is loosened, the pressing is released by rotating the nut 6-3 (ie, it is loosened upwards), and then the strip pressing plate 6-1 can be removed.

[0033] Furthermore, the bottom plate 1 is provided with a strip hole 1-1 (see Figure 2-3 The tool can be detachably fixed on the workbench through the strip hole 1-1 of the bottom plate 1.

[0034] The operation steps of the tooling of the utility model for positioning and clamping before welding the front fender bracket can be as follows:

[0035] First, place the first angle plate N-1 on the left block 2, so that the inner surface of one side of the first angle plate N-1 contacts the upper surface of the left block 2, and the inner surface of the other side of the first angle plate N-1 contacts the right side of the left block 2; and the two first positioning pins 8 are respectively inserted into the two first connecting holes N-11 of the first angle plate N-1; place the second angle plate N-2 on the pointed top 4-1, so that the inner surfaces of both sides of the second angle plate N-2 are respectively matched with the two inclined surfaces of the pointed top 4-1 for positioning, and the two second positioning pins 9 are respectively inserted into the two second connecting holes N-21 of the second angle plate N-2; insert the two elbows N-3 into the two profiling grooves 3-1 on the profiling block 3 for positioning, and at the same time make the two ends of the two elbows N-3 contact the first angle plate N-1 and the second angle plate N-2 respectively; at this time, the positioning constraints of the first angle plate N-1, the two elbows N-3 and the second angle plate N-2 are completed (see Figure 5 );

[0036] Then, the first pressing device 5 (corner cylinder) and the third pressing device 7 (corner cylinder) are started to press the first corner plate N-1 and the second corner plate N-2 respectively (see Figure 6 ); and then by operating the second pressing device 6 and the two elbows N-3 are pressed (see Figure 7-8 ), and then respectively realize the first angle plate N-1, the two elbows N-3 and the second angle plate N-2 to press and fix them to complete the positioning clamping (see Figure 7-8 ); At this time, the distribution position between the first angle plate N-1, the two elbows N-3 and the second angle plate N-2, as well as the relative positions between the holes thereon are accurate, and are respectively pressed and fixed to maintain the relative position positioning accuracy (see Figure 7-8 ).

[0037] In addition, after the positioning and clamping is completed, the contact between one end of the two elbows N-3 and the first angle plate N-1 can be welded, and the contact between the other end of the two elbows N-3 and the second angle plate N-2 can be welded (see Figure 1-2 (middle weld).

[0038] When welding is completed, the following unloading operation can be performed: first, loosen the clamping by rotating the nut 6-3, then remove the strip pressure plate 6-1, and then start the first clamping device 5 (angle cylinder) and the third clamping device 7 (angle cylinder) to automatically loosen and reset; then the welded workpiece (product) can be directly removed from the tooling seat 1, so that quick unloading can be achieved.

[0039] Therefore, the tooling of the utility model can realize the positioning and clamping of the first angle plate N-1, the two bends N-3 and the second angle plate N-2 when welding the front mudguard bracket, and ensure the accuracy of the relative position and direction, so that the distribution position and direction between the first angle plate N-1, the two bends N-3 and the second angle plate N-2 meet the requirements, and at the same time, the relative position between the various holes on the first angle plate N-1 and the second angle plate N-2 meets the precise requirements, thereby ensuring the welding accuracy and quality.

[0040] In addition, the front fender bracket is simple to operate during positioning and clamping, and is convenient to position and clamp, which meets the process requirements and can improve welding work efficiency.

[0041] In addition, when welding is completed, the welded workpiece can be loosened and removed, and the workpiece can be easily taken out. Unloading is very convenient, takes less time, and is safe to operate.

[0042] The specific structure of the pivoting cylinder can be based on existing technology. During the clamping operation, the pivoting cylinder first drives the clamping arm to rotate a certain angle to above the workpiece, then moves vertically downward to clamp the workpiece. After welding is completed, the pivoting cylinder automatically drives the clamping arm back to its original position along the clamping path, clearing the workpiece, allowing the operator to remove the workpiece smoothly and conveniently.

[0043] In other embodiments, the first pressing device 5, the second pressing device 6 and the third pressing device 7 can adopt structures such as clamps and cylinders to achieve pressing.

[0044] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
