[0013] It is easy to understand that according to the technical scheme of the utility model, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole or as the limitation or restriction of the technical scheme of the utility model.

[0014] A V-shaped clamp device as shown in Figure 1 The side of the V-shaped block 1 facing the moving pressing plate 2 is provided with a V-shaped notch symmetrical based on the center line of the V-shaped block 1. Under the premise of symmetrical structure of the V-shaped notch, the center position can be directly and accurately determined by placing the flat pipe nozzle in the V-shaped notch by using the self-centering principle of V-shaped structure. The V-shaped block 1 is fixedly arranged on the workbench, and the moving pressing plate 2 is movably arranged on the workbench and can reciprocate in the direction of approaching or moving away from the V-shaped block 1.

[0015] In order to facilitate pushing the moving pressing plate 2, a pushing device 4 is further arranged on the workbench, and the moving pressing plate 2 is fixed to the end of the pushing device 4 by the first baffle 3. The pushing device 4 can be a cylinder or the moving pressing plate 2 is arranged on the lead screw by the first baffle 3, and the lead screw is driven by a servo motor. The structure can be applied to the vice, the V-shaped block 1 is used as the fixed end, and the moving pressing plate 2 is used as the moving end, which is used to press the parts on the fixed end to complete the rapid positioning of the pipe sleeve parts and determine the center of the pipe sleeve parts.
