[0025] Among them, the first positioning block 2 and the two second positioning blocks 3 are both fixed on the tooling seat 1, and the two second positioning blocks 3 are respectively located on both sides of the first positioning block 2.

[0026] In this embodiment, refer to Figure 4 , the tooling seat 1 has a flat plate portion 1-1 and two L-shaped plate portions 1-2 symmetrically arranged at the left and right ends of the flat plate portion 1-1, and a strip hole 1-3 is provided on the L-shaped plate portion 1-2.

[0027] Specifically, the first positioning block 2 and the two second positioning blocks 3 are fixed on the upper surface of the flat plate portion 1-1 of the tooling seat 1. The first positioning block 2 is located in the middle of the flat plate portion 1-1, and the two second positioning blocks 3 are symmetrically located on the left and right sides of the flat plate portion 1-1.

[0028] Among them, a first positioning groove 2-1 is provided on the upper surface of the first positioning block 2; the two positioning pins 4 are both fixed on the upper surface of the first positioning block 2.

[0029] Among them, second positioning grooves 3-1 are provided on the upper surfaces of the two second positioning blocks 3.

[0030] Refer to Figure 4 , among them, the pressure rod 5 passes through the tooling seat 1. Specifically, a vertical through hole 1-11 is provided on the flat plate portion 1-1 of the tooling seat 1, and the pressure rod 5 passes through the vertical through hole 1-11 and is in sliding fit.

[0031] Among them, a pressure block 5-1 is fixedly provided at the upper end of the pressure rod 5, and the output end of the pressure cylinder 6 is connected to the lower end of the pressure rod 5. When pressing, the pressure cylinder 6 drives the pressure rod 5 to move downward, and presses the bent rod N-1 through the pressure block 5-1 (refer to Figures 8-9 ); when releasing, the pressure cylinder 6 drives the pressure rod 5 to move upward to release the bent rod N-1 by the pressure block 5-1 (refer to Figures 6-7 ).

[0032] Preferably, there are two pressure rods 5 which are distributed in parallel at intervals; the output end of the pressure cylinder 6 is fixedly connected to the lower ends of the two pressure rods 5 through a connecting plate 7. These two pressure rods 5 are used to tightly press the bent rod N-1 from left and right. Due to the symmetrical pressing at the left and right positions, compared with single-point pressing, the bent rod N-1 is more stable and not easy to loosen after pressing.

[0033] Preferably, a pressure groove 5-11 is provided on the lower side surface of the pressure block 5-1. Through the cooperation of the pressure groove 5-11 and the bent rod N-1 for pressing, the cooperation degree is better.

[0034] Preferably, the pressure groove 5-11 is a V-shaped groove or a semi-circular groove.

[0035] Preferably, the first positioning groove 2-1 is a V-shaped groove or a semi-circular groove. When the first positioning groove 2-1 cooperates with the first semi-circular arch portion N-21 in the middle of the intermediate plate N-2, the center of the first semi-circular arch portion N-21 can be accurately positioned.

[0036] Preferably, the second positioning groove 3-1 is a V-shaped groove or a semi-circular groove. When the second positioning groove 3-1 cooperates with the second semi-circular arch portion N-31 in the middle of the side support plate N-3, the center of the second semi-circular arch portion N-31 can be accurately positioned.

[0037] The operation steps of the tooling of the present utility model during clamping can be as follows:

[0038] First, place the intermediate plate N-2 on the first positioning block 2, so that the first semi-circular arch portion N-21 of the intermediate plate N-2 is placed in the first positioning groove 2-1 for positioning. The upper surface of the first positioning block 2 horizontally supports the lower flat surface of the intermediate plate N-2 to limit rotation. The two positioning pins 4 are inserted into the two mounting holes N-22 of the intermediate plate N-2 for accurate positioning, so as to complete the positioning of the intermediate plate N-2; place the two side support plates N-3 on the two second positioning blocks 3 respectively, so that the second semi-circular arch portions N-31 in the middle of the two side support plates N-3 are respectively placed in the second positioning grooves 3-1 of the two second positioning blocks 3 for positioning. The upper surfaces of the two second positioning blocks 3 horizontally support the lower flat surfaces of the two side support plates N-3 to limit rotation, so as to complete the positioning of the two side support plates N-3 (see Figures 6-7 );

[0039] Then, insert the middle flat section N-11 of the bent rod N-1 into the first semi-circular arch portion N-21 in the middle of the intermediate plate N-2; and insert the two side flat sections N-12 of the bent rod N-1 into the second semi-circular arch portions N-31 of the two side support plates N-3 respectively, and make the back end faces of the two side support plates N-3 flush with the two end faces of the bent rod N-1 respectively (see Figures 6-7 );

[0040] Finally, start the operation of the pressing cylinder 6 to drive the two pressing rods 5 to move downward, so that the pressing blocks 5-1 on the two pressing rods 5 press downward and tightly hold the bending rod N-1 from left and right. The bending rod N-1 will simultaneously press the middle plate N-2 and the two side support plates N-3 downward. At this time, the positioning and clamping among the middle plate N-2, the two side support plates N-3 and the bending rod N-1 are completed. At the same time, the middle plate N-2, the two side support plates N-3 and the bending rod N-1 are simultaneously fixed and constrained and maintain accurate relative position positioning (see Figures 8-10 ).

[0041] In addition, after the above positioning and clamping are completed, welding work can be carried out at the contact points among the middle plate N-2, the two side support plates N-3 and the bending rod N-1 (see the welding points in Figure 1 ). After the welding is completed, the following unclamping operation can be carried out:

[0042] First, start the operation of the pressing cylinder 6 to drive the two pressing rods 5 to move upward. The pressing blocks 5-1 on the two pressing rods 5 move upward and simultaneously release the bending rod N-1. Then, the welded workpiece (product) can be directly removed from the tooling seat 1 (see Figures 6-7 ). Therefore, rapid unclamping can be achieved.

[0043] Therefore, the tooling of the present utility model can realize the positioning and clamping among the middle plate N-2, the two side support plates N-3 and the bending rod N-1 during the welding of the pedal side bracket, and ensure the accuracy of the relative position and direction, thereby ensuring the welding accuracy and quality.

[0044] In addition, the operation of the pedal side bracket during clamping is simple, and positioning and pressing are both very convenient, which can meet the technological requirements, is safe in operation, and can improve the welding work efficiency.

[0045] In addition, after the welding is completed, the welded workpiece can be released and unclamped, the workpiece can be easily taken out, the unclamping is very convenient, it takes less time, and the operation is also safe.
