Detailed Description
As shown in fig. 1 to 3, the lead frame clamping device 100 includes a base 101. The base 101 is provided with a cylinder 102. The number of cylinders 102 is four. A bracket 103 is attached to each cylinder 102. One end of each bracket 103 is connected with the cylinder 102, and the other end is provided with a fixed frame 104. The fixing frame 104 includes a frame body 105 and a mounting plate 106. The frame body 105 is provided with a notch 107. The frame body 105 is provided with a pin shaft 108. The pin 108 passes through the notch 107. The mounting plate 106 is provided with a through groove 109, and the through groove 109 is arc-shaped. The mounting plate 106 is coupled to the frame body 105.
The middle of the mounting bracket 110 is located in the gap 107, and the middle is sleeved on the pin 108 and can rotate around the pin 108. One end of the mounting bracket 110 is connected to the clamping rod 120, and the other end is provided with a connecting member 111. The connecting piece 111 is inserted into the through groove 109 and can move along the through groove 109, and the position of the connecting piece 111 in the through groove 109 can be adjusted. The connecting member 111 is provided with a fastening member 112. The fastener 112 is detachably connected to the connecting member 111. When the position of the connecting member 111 in the through slot 109 is appropriate, the mounting frame 110 can be fixedly connected with the fixing frame 104 by the fastening member 112. As an example shown, the fastener 112 is a nut. The fastener 112 is threadedly coupled to the connector 111. When the position of the connector 111 in the through groove 109 needs to be adjusted, the connection between the fastener 112 and the connector 111 is released, the connector 111 is slid to a desired position in the through groove 109, the fastener 112 is connected to the connector 111, and the mounting plate 106 is tightened to fix the connector 111 at a predetermined position. One end of the extension spring 113 is connected to the mounting bracket 110, and the other end is connected to the fixing bracket 104. The base 101 is further provided with a stopper 115, and the stopper 115 is located on the moving path of the fixing frame 104 and used for stopping the fixing frame 104 to limit the moving distance of the fixing frame 104.
