Embodiment Construction

[0015] see figure 1 , figure 2 , the structure of the flexible clamping mechanism in this embodiment is set as:

[0016] The driving cylinder 7 is fixedly connected on the frame bottom plate 1a, and the bottom end of the connecting plate 8 is hinged at the piston rod end of the driving cylinder 7;

[0017] The bottom end of the main connecting plate 3 is hinged on the frame backplane 1b through the fixed rotating shaft 2, and a waist hole chute 3a is set in the middle of the main connecting plate 3;

[0018] The clamping arm 13 is hinged to the top of the main connecting plate 3 through the rotating shaft 14 in the middle to form a top hinge point. On the main connecting plate 3, the primary chuck 5 is installed below the top hinge point, and the secondary chuck 6 is installed on the clamp the inner end of the arm 13;

[0019] The top elbow of the lower connecting plate 8 and the bottom elbow of the upper connecting plate 11 are hinged through the main shaft 4, and the mai...

Abstract

The invention discloses a flexible clamping mechanism, which is characterized in that a driving cylinder is fixedly connected to a stander baseplate, and the rod end of a piston rod of the driving cylinder is articulated to the bottom end of a lower connecting plate; the bottom end of a main connecting plate is articulated to a stander backplate through a fixed rotating shaft, and the middle part of the main connecting plate is provided with a kidney-shaped hole sliding chute; the middle part of a clamping arm is articulated with the top of the main connecting plate through a rotating shaft to form a top articulation point, a primary chuck is arranged on the main connecting plate and positioned below the top articulation point, and a secondary chuck is arranged at the inner end of the clamping arm; a top elbow of the lower connecting plate is articulated with a bottom elbow of the upper connecting plate through a mainshaft, and the mainshaft can freely slide in the kidney-shaped sliding chute of the main connecting plate; and the top end of the upper connecting plate is articulated with the outer end of the clamping arm through a rotating shaft, a bolt is fixedly arranged at the bottom elbow of the upper connecting plate, one end of a tension spring is fixed on the bolt, and the other end of the tension spring is fixed on the fixed rotating shaft. The flexible clamping mechanism disclosed by the invention achieves the function of sequential clamping at two positions and is simple in structure and reliable to actuate.

Description

technical field [0001] The invention relates to a flexible clamping mechanism, more specifically, a flexible clamping mechanism applied to a welding jig for an automobile body-in-white by using an air cylinder to realize the sequential clamping function of two positions. Background technique [0002] In the automobile body-in-white welding fixture, it is often necessary to sequentially realize the clamping function of the upper and lower positions of the body panels in one place. The common practice is to use two cylinders for secondary swing, and gradually realize the clamping function of two positions. This method needs to use two cylinders, and it is necessary to set the sequential clamping sequence of the cylinders to achieve the function of sequential clamping. The structure of the whole mechanism is cumbersome and difficult to maintain. Contents of the invention [0003] The purpose of the present invention is to avoid the disadvantages of the above-mentioned prior...
