Figure 1 to Figure 7As shown, a detection device for a rear torsion beam welding assembly provided by an embodiment of the utility model is suitable for detecting and positioning relevant shape and position dimensional indicators of a rear torsion beam welding assembly 8, and mainly comprises: a detection table 1, two positioning mechanisms 2, two first linear guide mechanisms 3, two profile detection mechanisms 4, two first characteristic hole detection mechanisms 5, two second characteristic hole detection mechanisms 6, and a synchronous screw mechanism 7; specifically, the first linear guide mechanism 3, the profile detection mechanism 4, the first characteristic hole detection mechanism 5, and the second characteristic hole detection mechanism 6 are all symmetrically distributed on the left and right sides of the synchronous screw mechanism 7 and arranged on the upper plane of the detection table 1 to adapt to the structural shape of the rear torsion beam welding assembly 8 that is symmetrical on the left and right sides, the positioning mechanism 2 is arranged above the first linear guide mechanism 3 and is mechanically connected to the first linear guide mechanism 3, and the linear movement of the positioning mechanism 2 on the first linear guide mechanism 3 is mainly achieved through the structural form of the guide rail 31 and the slider 32 in the first linear guide mechanism 3, and the profile detection mechanism The second linear guide mechanism 41 disposed below the profile detection mechanism 4 is used to realize the linear movement of the entire profile detection mechanism 4, and the plurality of sensors (e.g., dial gauge) in the profile detection mechanism 4 are used to realize the surface detection of the specific plane of the rear torsion beam welding assembly 8, and the detection pins in the first characteristic hole detection mechanism 5 and the second characteristic hole detection mechanism 6 are used to perform corresponding actions to realize the detection of the position of the specific hole in the rear torsion beam welding assembly 8 to ensure that the shape and position indicators of the rear torsion beam welding assembly 8 meet the requirements; it is worth noting that the action control form of the profile detection mechanism 4, the first characteristic hole detection mechanism 5, and the second characteristic hole detection mechanism 6 here can adopt a manual mode, or can be replaced by an automatic control mode through a driving mechanism such as a cylinder to adapt to different production modes of users, and the control form is not specifically limited here; the synchronous screw mechanism 7 is mechanically connected with the left and right positioning mechanisms 2 through a screw to realize the synchronous movement of the left and right positioning mechanisms 2 to move closer to or away from each other. The detection device of a rear torsion beam welding assembly provided by the embodiment of the utility model realizes the positioning process of two groups of positioning mechanisms 2 with a long distance being completed with one action, which not only greatly saves time and manpower, but also has a higher positioning accuracy than the structural form in which the two groups of positioning mechanisms 2 are positioned separately, which not only meets the beat time of this workstation on the assembly line, but also meets the high-precision requirements of the product, so that the detection device of this type of rear torsion beam welding assembly has a great breakthrough in the original structure, and solves the problem that accurate positioning could not be achieved in a short time on the previous production line.

[0025] In a detection device for a rear torsion beam welding assembly provided by an embodiment of the utility model, more specifically, the synchronous screw mechanism 7 includes a first screw 71, a second screw 72, a first screw nut 73, a second screw nut 74, and a handwheel 75. The first screw nut 73 is located below a positioning mechanism 2 and is mechanically connected thereto, the first screw nut 73 is threadedly connected to the first screw 71, the second screw nut 74 is located below another positioning mechanism 2 and is mechanically connected thereto, the second screw nut 74 is threadedly connected to the second screw 72; the first screw 71 and the second screw 72 are respectively located on both sides of the synchronous screw mechanism 7 and are drivingly connected to the handwheel 75 for realizing the synchronous rotation of the first screw 71 and the second screw 72 driven by the handwheel 75, and further driving the left and right positioning mechanisms 2 to synchronously move closer to or away from each other. By shaking the handwheel 75 in the synchronous screw mechanism 7, the reversing mechanism in the synchronous screw mechanism 7 is used to realize the synchronous rotation of the first screw 71 and the second screw 72, wherein the spiral directions of the first screw 71 and the second screw 72 are opposite. In this way, by driving the first screw 71, the first screw nut 73 and a corresponding positioning mechanism 2 thereon are driven to move linearly, and by driving the second screw 72, the second screw nut 74 and another corresponding positioning mechanism 2 thereon are driven to move linearly. In this way, the positioning mechanisms 2 on the left and right sides of the synchronous screw mechanism 7 can achieve synchronous movement towards or away from each other; it is worth noting that the first screw 71 and the second screw 72 here can also be an integrated structure, as long as the spiral directions at both ends are opposite, the same effect can be achieved, and no specific restrictions are imposed on the structural form of the first screw 71 and the second screw 72.

Figure 2 and Figure 5 A structural form of a guide rail 31 and a slider 32 is shown respectively. Each first linear guide mechanism 3 adopts a structural form in which two guide rails 31 and two sliders 32 are slidably matched. The slider 32 needs to be adapted to the cross-sectional shape of the guide rail 31 to ensure the movement accuracy and stability of the positioning mechanism 2.
