[0014] The specific embodiment of the utility model is described in detail below in combination with the drawings and the preferred embodiment.

[0015] As Figures 1-3 shown, a two-way positioning swing clamping mechanism includes a locking cylinder 1, a circular cylinder 2, a foot stand 3, a mounting plate 4, a swing arm 5, a pressing arm 6, a pressing head 7 and a fixing frame 8, the mounting plate is fixed on the foot stand, one side of the locking cylinder is hinged to the side of the mounting plate, the piston rod of the locking cylinder is hinged to one end of the swing arm, the middle part of the swing arm is hinged to the upper part of the mounting plate, the circular cylinder is hinged to the upper part of the swing arm, the piston rod of the circular cylinder is hinged to the first end 9 of the pressing arm, the second end 10 of the pressing arm is hinged to the front end of the swing arm, the third end 11 of the pressing arm is fixed with the pressing head, the lower part of the swing arm is fixed to the fixing frame through the connecting block, and the fixing frame is used for positioning the workpiece. The pressing arm passes through the middle part of the fixing frame, the locking cylinder can drive the swing arm to swing, the circular cylinder can drive the pressing arm to swing, so that the pressing head drives the workpiece and the fixing frame to be fixed together.

[0016] In order to detect the position of the workpiece, the middle part of the fixing frame is provided with a proximity switch 12. In order to make the workpiece smoothly enter the fixing frame, the two sides of the fixing frame are provided with guide blocks 13, the upper part is provided with a guide plate 14, and the inner side is provided with a positioning pin 15. The workpiece can be positioned by the positioning pin. In order to fix the workpiece, the fixing frame is provided with a magnetic support 16, and the magnetic support is provided with a magnet 17. The magnet adsorbs the workpiece in the fixing frame.

[0017] As Figure 4 and Figure 5 shown, in the welding production line, signals are taken from the glue coating robot to the locking cylinder and the circular cylinder, the cylinder is electrified and aerated, and the workpiece realizes 0 ° to 70 ° reciprocating motion.

[0018] The initial state of the mechanism is that the locking cylinder retracts, and the circular cylinder retracts. After the manual loading station finishes loading, the proximity switch detects that the workpiece is loaded in place, the circular cylinder first extends, after extending to the position, the PLC sends a signal to the gluing robot, and the robot starts gluing. After gluing one side, the robot sends a signal to the PLC, the cylinder receives the signal and is powered and aerated, the locking cylinder extends again, driving the mechanism to rotate counterclockwise by 70°, after rotating to the position, the locking cylinder magnetic ring to position signal light is bright, at this time the robot can go to glue the back of the workpiece, after gluing is completed, the robot returns to the safety position, sends a signal to the cylinder, the locking cylinder first retracts, driving the mechanism to rotate clockwise by 70°, after rotating to the position, the locking cylinder magnetic ring to position signal light is bright, the circular cylinder starts to retract, and the mechanism is opened, so that the next station robot can start to take the workpiece. Thus, a work flow is completed.

[0019] After the mechanism has the bidirectional positioning clamping effect, the bidirectional positioning repeat accuracy can be effectively improved, the single glue gun can complete the gluing of the front and back surfaces of the workpiece, the transition point and gun changing beat during the gluing of the robot are saved, and the cost control of the automatic line is promoted.

[0020] 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, and these improvements and refinements should also be considered within the scope of protection of the present application.
