Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0047] In the specific embodiment of the present invention, see Figure 2-Figure 8 A supporting fixture includes: a base 4, which can be set to a rotatable and liftable base, so that workers do not need to adjust their positions during welding, which is more relaxed;

[0048] It also includes a first fixture 1, a second fixture 2 and a third fixture 3, wherein the first fixture 1, the second fixture 2 and the third fixture 3 are all installed on the base 4, the first fixture 1 is used to position the component A, the second fixture 2 is used to position the component B, and the third fixture 3 is used to position the component C;

[0049] See Figure 2 , Figure 3 The first clamp 1 includes a first supporting wall 11, a first adjusting rod 12, an eccentric wheel 13, a first positioning block 14, a tension spring 15 and a limiting cylinder 16;

[0050] The bottom of the first supporting wall is mounted on the base by bolts, and the limiting cylinder is welded to the right side of the first supporting wall;

[0051] An adjusting cylinder 111 is welded on the left side of the first supporting wall 11, and the limiting cylinder 16 is coaxial with the adjusting cylinder 111;

[0052] The first adjusting rod 12 is sleeved and installed in the adjusting cylinder 111;

[0053] The eccentric wheel 13 is installed at the right end of the first adjusting rod 12, and the eccentric wheel 13 is installed in the limiting cylinder 16;

[0054] The limiting cylinder 16 is provided with a first positioning block mounting hole 161, and the first positioning block 14 is installed in the first positioning block mounting hole 161;

[0055] A tension spring mounting seat 162 is provided on the inner side of the limiting cylinder 16, and the tension spring mounting seat 162 is coaxial with the first positioning block mounting hole 161; a limiting platform 141 is welded on the inner end of the first positioning block 14, one end of the tension spring 15 is sleeved on the tension spring mounting seat 162, and the other end is installed on the limiting platform 141 and limited by the limiting platform 141, and the tension spring 15 is used to adjust the reset of the first positioning block 14;

[0056] The outer end of the first positioning block 14 is provided with a tightening head 142, which is tightly pressed against the inner wall of the component A during operation to position the component A, thereby ensuring that the component A does not rotate or shake.

[0057] The adjusting cylinder 111 and the first adjusting rod 12 are both provided with a first positioning hole 112, and a positioning rod 113 is installed in the first positioning hole 112. When the first adjusting rod 12 is rotated to drive the eccentric wheel 13 to rotate, the first positioning block 14 extends outward to tighten the component A. At this time, the adjusting cylinder 111 is aligned with the first positioning hole on the first adjusting rod 12, and then the positioning rod 113 is manually inserted into the two first positioning holes at the same time to prevent the first adjusting rod 12 from rotating, thereby ensuring that the positioning of the first positioning block 14 will not be affected.

[0058] In the specific embodiment of the present invention, see Figure 2 - Figure 3, the outer side surface of the tightening head 141 is in conformity with the inner side surface of component A to ensure that the inner side surface of component A will not be damaged.

[0059] In the specific embodiment of the present invention, see Figure 2-Figure 3 , three first positioning blocks 14 are provided, and correspondingly, three tension springs 15 are provided, three tension spring mounting seats 162 are provided, and three first positioning block mounting holes 161 are provided;

[0060] The three positioning blocks simultaneously position component A to ensure that component A does not deviate or rotate.

[0061] In the specific embodiment of the present invention, see Figure 2 , Figure 5 , Figure 6 , the second clamp 2 includes a second supporting wall 21, a second adjusting rod 22, a first adjusting spring 23, a second positioning block 24, a first supporting rod 25 and a third positioning block 26;

[0063] A first adjusting spring mounting seat 212 is disposed on the second supporting wall 21, and the first adjusting spring mounting seat 212 is coaxial with the adjusting hole 211;

[0064] The second positioning block 24 is installed at the inner end of the second adjusting rod 22;

[0065] One end of the first adjusting spring 23 is mounted on the first adjusting spring mounting seat 212, and the other end is mounted on the second positioning block 24;

[0066] The first support rod 25 and the second support wall 21 are arranged on the base 4 opposite to each other;

[0067] The third positioning block 26 is installed on the first supporting rod 25;

[0068] The third positioning block 26 is opposite to the second positioning block 24, and the component B is located between the second positioning block 24 and the third positioning block 26;

[0069] During operation, the second positioning block 24 and the third positioning block 26 clamp component B at the same time. When component B is fixed, the contact portion between component B and component A is exactly the welding position, so no adjustment is required. At the same time, the welding positions between component B and component A are all located in positions that are easy to control. During welding, just move the welding machine normally according to the welding trajectory without adjusting component A and component B, thereby ensuring that the positioning between component A and component B is more accurate. Since there is no need for secondary positioning, the welding speed is faster, thereby effectively improving work efficiency.

[0070] In the specific embodiment of the present invention, see Figure 7 , Figure 8 , the third clamp 3 includes a second support rod 31, a first clamp block 32, a second clamp block 33 and a clamping spring 34;

[0071] The second support rod 31 is installed on the base;

[0072] The first clamping block 32 is installed at the top of the second supporting rod 31;

[0073] The inclination angle of the first clamping block 32 is the same as that of the component C. Figure 1 The relative angle between the two components is adapted to that of component A;

[0074] The first clamping block 32 is provided with a first positioning hole 321, and a first positioning seat 322 is provided in the first positioning hole 321; the second clamping block 33 is provided with a second positioning hole 331, and a second positioning seat 332 is provided in the second positioning hole 331; one end of the clamping spring is mounted on the first positioning seat, and the other end is mounted on the second positioning seat;

[0075] During operation, the first clamp and the second clamp limit component C, and at the same time ensure that the contact position between component C and component A is exactly the welding position, and component C is tilted upward. Only a slight adjustment of the welding gun is required to meet the welding conditions. There is no need to adjust components A and C during the entire process, thereby greatly improving the welding accuracy and work efficiency.

[0076] In the specific embodiment of the present invention, see Figure 7 , Figure 8 , the clamping springs are provided in two groups, each group having two;

[0077] Correspondingly, the first positioning seat, the positioning hole and the second positioning seat are each provided with two groups;

[0078] The clamping force of the second clamping block is ensured to be stable, so that the force on component C is uniform, thereby ensuring the stability of component C.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
