[0005] Preferably, the guide plate is composed of a left guide plate, a right guide plate and a bottom plate, the left guide plate and the right guide plate are fixed on the two sides of the bottom plate respectively, and the guide grooves are arranged on the left guide plate and the right guide plate respectively.

[0006] Preferably, the guide groove is in inverted J shape.

[0007] Preferably, the left guide plate, the right guide plate and the bottom plate are integrally formed.

[0008] Preferably, the guide block is in T shape.

[0009] Preferably, the hinge shaft is slidably connected with the guide groove.

[0010] The utility model has the advantages of simple structure, reasonable design, flexible and convenient application, and the opening route of the clamping block can be changed from the existing circular track to the combined line segment of straight line and curve, so that the movement track can effectively avoid the workpiece, and the performance is more safe and reliable. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is a structural schematic view of the utility model;

[0012] Figure 2 It is a sectional view of the utility model. DETAILED DESCRIPTION

[0013] The specific implementation of the present application will be described in detail below in conjunction with the drawings and preferred embodiments.

[0014] As shown in Figure 1 and Figure 2 A nonlinear clamping mechanism, comprising a clamping arm 1, a guide block 2, a guide plate and a cylinder 3, the side of the guide plate is provided with a guide groove 4, the guide groove is inverted J-shaped, the two sides of the guide block are slidably connected with the guide groove through a guide shaft 5, the guide shaft makes nonlinear motion with the guide groove, the clamping arm is fixed on the upper end of the guide block, the bottom of the guide block is hingedly connected with the piston rod of the cylinder through a hinge shaft 6, the hinge shaft is slidably connected with the guide groove. The cylinder is fixed on the bottom of the guide plate. The clamping mechanism is driven to move with the guide plate by the expansion and contraction of the cylinder, thereby realizing nonlinear motion to avoid scratching the body-in-white panel. The opening route of the clamping block is changed from the existing circular trajectory to a combined line segment composed of a straight line and a curve, such a motion trajectory can effectively avoid the workpiece and has more safe and reliable performance

[0015] Specifically, the guide plate is composed of a left guide plate 7, a right guide plate 8 and a bottom plate 9, and the left guide plate, the right guide plate and the bottom plate are integrally formed. The left guide plate and the right guide plate are respectively fixed on the two sides of the bottom plate, and the guide grooves are respectively arranged on the left guide plate and the right guide plate.

[0016] Specifically, in order to facilitate connection, the guide block is T-shaped structure.

[0017] It should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
