Embodiment 1

[0031] Example 1 A positioning and clamping mechanism for welding the rear stabilizer bar mounting bracket of the rear sub-frame

[0032] This embodiment is a positioning and clamping unit, which is used to clamp the rear stabilizer bar installation bracket of the rear sub-frame on the left side, that is, the workpiece 14 .

[0033] The positioning and clamping unit includes a reference platform, which is composed of a base 3 on the left and a support block 10 on the right in solid connection. A cylinder 1 with a cylinder body that can slide left and right along the reference platform is freely placed above the reference platform, and the telescopic rod of the cylinder 1 stretches left and right.

[0034] The positioning and clamping unit also includes a left jaw 1 and a right jaw 9 that move axially due to the horizontal movement of the cylinder 1, such as image 3 shown. Left claw 7 such as Figure 4 As shown, it is firmly connected with the cylinder body. The right cl...

Embodiment 2

[0053] Example 2 A positioning and clamping mechanism for welding the rear stabilizer bar mounting bracket of the rear sub-frame

[0054] This embodiment is a positioning and clamping unit, which is used for clamping the rear stabilizer bar mounting bracket of the rear sub-frame on the right side. The positioning and clamping unit is an equivalent replacement made according to the essence of embodiment 1, and is used for clamping the rear stabilizer bar mounting bracket of the rear sub-frame on the left side.

[0055] The overall structure of this embodiment is symmetrical with the structure provided by Embodiment 1 with respect to the vertical plane along the extension direction of the telescopic rod; example 1 figure 1 The structure of the workpiece 14 in the left and right sides is symmetrical.

[0056] The working principle of this embodiment is the same as that of Embodiment 1, and the working process is corresponding.

Embodiment 3

[0057] Example 3 A positioning and clamping mechanism for welding the rear stabilizer bar mounting bracket of the rear sub-frame

[0058] This embodiment includes two positioning and clamping units, which are set apart from each other on the left and right sides. The structure of the unit relatively on the left is exactly the same as that of Embodiment 1, and the working principle and working process are also exactly the same and located on the left; the structure of the unit relatively located on the right is exactly the same as that of Embodiment 2, and is located on the right.

[0059] Both units work simultaneously. Such as Image 6 As shown, when the present embodiment works, the two positioning and clamping units are assembled on the horizontal sliding table 19 connected with the main body table of the integral welding tool through the longitudinal sliding table 18. The whole tooling is an existing product, which is used for welding between the stabilizer bar mountin...

Abstract

The invention discloses a positioning and clamping mechanism for welding the mounting bracket of the rear lateral stabilizer bar of the rear sub-frame. The inner jaws and outer jaws are fixedly connected with the cylinder body and the telescopic rod; the workpiece limiter is set on the reference table, and the outer jaws will be closed due to contact with the outer edge of the workpiece during the contraction process of the telescopic rod from the extended limit state. Stop the action, and at this time, the cylinder body moves from inside to outside relative to the reference table until the inner jaws touch the inner edge of the workpiece. The invention uses a single cylinder and two claws to cooperate to realize the clamping and precise positioning of the bracket along the length direction, simplify the structure, reduce the space layout, and expose all the weld seams after the positioning and clamping of the tooling, which can meet 100% automatic welding of robots. Reachability, thereby improving production efficiency and ensuring welding quality. The invention is suitable for positioning and clamping when welding the mounting bracket of the rear lateral stabilizer bar of the rear sub-frame.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to an auxiliary tool for welding, in particular to a positioning and clamping mechanism for welding a rear lateral stabilizer bar mounting bracket of a rear sub-frame. Background technique [0002] The stabilizer bar is an auxiliary elastic component in the automobile suspension, which is used to prevent the body from excessive lateral roll when turning, reduce the degree of lateral roll of the car, keep the body as balanced as possible, and improve ride comfort. The stabilizer bar is a torsion bar spring made of spring steel. It is in the shape of a "U" and is placed horizontally at the front and rear ends of the car. They are respectively fixed on the left and right suspensions. When the body only moves vertically, the suspension on both sides deforms the same, and the stabilizer bar does not work. When the car turns, the body rolls, the suspension on both sides jumps inconsis...
