[0024] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, an automobile handbrake welding tooling includes a fixture base plate 1. A bearing platform 2 for clamping a handbrake lever 11 and a fixed seat 5 for clamping two groups of side plates are respectively installed on the fixture base plate 1. A clamping table 4 is fixedly installed on one side of the fixture base plate 1 close to the fixed seat 5. A notch 8 for accommodating one end of the handbrake lever 11 is opened at the top of the clamping table 4. A limiting component 3 is arranged on the bearing platform 2, and the limiting component 3 is used for limiting the other end of the handbrake lever 11; positioning structures 7 are arranged on both sides of the fixed seat 5, and the positioning structures 7 are used for positioning the two groups of side plates; the positioning structure 7 includes a positioning shaft 71 penetrating through the two groups of side plates. One end of the positioning shaft 71 is sleeved with a positioning cylinder 72. A clamping block 6 is fixedly installed on the fixed seat 5. A through hole 10 for accommodating the positioning shaft 71 and the positioning cylinder 72 is opened inside the clamping block 6. Moving plates 79 are fixedly installed at the ends of the positioning shaft 71 and the positioning cylinder 72. An auxiliary block 74 is fixedly installed at the top of the moving plate 79. A sticking rod 75 penetrates through the auxiliary block 74. A spring 76 is sleeved outside the sticking rod 75; A pressing cylinder 73 is fixedly installed on the fixture base plate 1, and the output end of the pressing cylinder 73 is fixedly connected to the moving plate 79; Upper end blocks 77 are fixedly installed on both sides of the clamping table 4, and lower end blocks 78 are fixedly installed on both sides of the fixed seat 5. The upper end blocks 77 and the lower end blocks 78 correspond to each other and are used for clamping the two side plates.

[0025] In this implementation mode, first place the first side plate 12 and the second side plate 13 on both sides of the fixed seat 5 respectively, so that the two groups of side plates are respectively located between the fixed seat 5 and the clamping block 6. The first side plate 12 and the second side plate 13 are respectively clamped with the upper end block 77 and the lower end block 78 for primary positioning. Then, drive the positioning shaft 71 and the positioning cylinder 72 on the moving plate 79 to move simultaneously towards the middle direction of the fixed seat 5 through the pressing cylinder 73. After the positioning shaft 71 penetrates through the through hole 10 in the clamping block 6 and then penetrates through the first side plate 12 and the second side plate 13, the positioning shaft 71 and the positioning cylinder 72 are clamped with each other. At the same time, the auxiliary block 74 on the moving plate 79 moves towards the two groups of side plates, and the sticking rods 75 on the auxiliary block 74 contact the two groups of side plates at the same time. Under the action of the spring 76, the first side plate 12 and the second side plate 13 are respectively pressed for secondary positioning;

[0026] Then, one end of the handbrake lever 11 is placed in the notch 8 in the clamping table 4, and the other end is restricted by the limiting component 3. After assembly, the joints of the handbrake lever 11 with the first side plate 12 and the second side plate 13 are welded by a welding torch. The whole can be assembled and welded quickly, and the positioning and limiting effects are good.

[0027] As an implementation manner, as Figure 6 shown, both the positioning shaft 71 and the positioning cylinder 72 are provided in two groups. One end of the positioning shaft 71 is provided with a conical head, and the length of the sticking rod 75 is less than the lengths of the positioning shaft 71 and the positioning cylinder 72.

[0028] In this implementation manner, two groups of positioning shafts 71 and positioning cylinders 72 are respectively arranged on both sides of the first side plate 12 and the second side plate 13. By using the positioning shafts 71 and the positioning cylinders 72 to move simultaneously towards the middle direction of the fixed seat 5, after the positioning shaft 71 passes through the through hole 10 in the clamping block 6 and then passes through the first side plate 12 and the second side plate 13, the positioning shaft 71 and the positioning cylinder 72 are mutually clamped to perform secondary positioning on the first side plate 12 and the second side plate 13.

[0029] As an implementation manner, as Figure 3 and Figure 4 shown, the clamping blocks 6 are arranged in mirror symmetry with the center of the clamping table 4 as the reference. Grooves corresponding to both ends of the side plate are respectively opened in the upper end block 77 and the lower end block 78, and the lower end block 78 is located between the fixed seat 5 and the clamping block 6.

[0030] In this implementation manner, first, the first side plate 12 and the second side plate 13 are respectively placed on both sides of the fixed seat 5, so that the two groups of side plates are respectively located between the fixed seat 5 and the clamping block 6. By using the grooves corresponding to both ends of the side plate respectively opened in the upper end block 77 and the lower end block 78, the grooves are in contact with the first side plate 12 and the second side plate 13, and thus are respectively clamped with the upper end block 77 and the lower end block 78 for rough positioning.

[0031] As an implementation manner, as Figure 3 、 Figure 4 and Figure 5 shown, the limiting component 3 includes a rotary cylinder 31 fixedly installed on one side of the bearing table 2. The output end of the rotary cylinder 31 is fixedly connected with a pressing block 32; a bracket 33 is fixedly installed on the other side of the bearing table 2, and a spring telescopic rod 34 is fixedly installed inside the bracket 33. One end of the spring telescopic rod 34 is fixedly installed with a gasket 35.

[0032] In this implementation manner, one end of the handbrake lever 11 is placed in the notch 8 in the clamping table 4, and the other end is clamped until it abuts against the gasket 35. Under the action of the spring telescopic rod 34, the gasket 35 and the notch 8 of the clamping table 4 limit the handbrake lever 11. At the same time, the rotary cylinder 31 drives the pressing block 32 to press downwards to tightly limit the outside of the handbrake lever 11. Finally, the joints of the handbrake lever 11 with the first side plate 12 and the second side plate 13 are welded by a welding torch.

[0033] As an implementation manner, as Figure 1 shown, a V-shaped groove 9 for accommodating the handbrake lever 11 is formed on the carrier table 2, and the height of the V-shaped groove 9 corresponds to the height of the notch 8.

[0034] In this implementation manner, the handbrake lever 11 is carried by the V-shaped groove 9, and the settings of the notch 8, the V-shaped groove 9 and the gasket 35 clamp the two ends and the middle part of the handbrake lever 11 respectively, avoiding movement during welding and affecting the welding effect.

[0035] As an implementation manner, as Figure 3 and Figure 4 shown, the bracket 33 is an L-shaped structure, and the spring telescopic rod 34 corresponds to the handbrake lever 11.

[0036] In this implementation manner, one end of the handbrake lever 11 is placed in the notch 8 in the clamping table 4, and the other end is clamped against the gasket 35. Under the action of the spring telescopic rod 34, the gasket 35 and the notch 8 of the clamping table 4 cooperate to limit the handbrake lever 11 of different lengths.

[0037] Working principle: During use, first place the first side plate 12 and the second side plate 13 on both sides of the fixed seat 5 respectively, so that the two groups of side plates are respectively located between the fixed seat 5 and the clamping block 6. The first side plate 12 and the second side plate 13 are respectively clamped with the upper end block 77 and the lower end block 78 for rough positioning;

[0038] After rough positioning, the pressing cylinder 73 drives the positioning shaft 71 and the positioning cylinder 72 on the moving plate 79 to move simultaneously towards the middle of the fixed seat 5. After the positioning shaft 71 passes through the through hole 10 in the clamping block 6 and then passes through the first side plate 12 and the second side plate 13, the positioning shaft 71 and the positioning cylinder 72 are clamped with each other. At the same time, the auxiliary block 74 on the moving plate 79 moves towards the two groups of side plates, and the attaching rods 75 on the auxiliary block 74 contact the two groups of side plates simultaneously. Under the action of the spring 76, the first side plate 12 and the second side plate 13 are respectively pressed for fine positioning; then one end of the handbrake lever 11 is placed in the notch 8 in the clamping table 4, and the other end is clamped against the gasket 35. Under the action of the spring telescopic rod 34, the gasket 35 and the notch 8 of the clamping table 4 cooperate to limit the handbrake lever 11 of different lengths. At the same time, the rotating cylinder 31 drives the pressing block 32 to press downwards to limit the outside of the handbrake lever 11. Finally, the joint of the handbrake lever 11 with the first side plate 12 and the second side plate 13 is welded by a welding torch, and the whole can be quickly assembled and welded with good positioning and limiting effects.
