Detailed Description
As shown in fig. 1-3, the leadframe clamping device 100 includes a base 101. A cylinder 102 is mounted on the base 101. The number of cylinders 102 is four. One 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 fixing frame 104. Mount 104 includes a frame body 105 and a mounting plate 106. The frame 105 is provided with a notch 107. The frame 105 is provided with a pin 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 connected to the frame 105.
The middle part of the mounting frame 110 is positioned in the notch 107, and the middle part is sleeved on the pin shaft 108 and can rotate around the pin shaft 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 fastener 112. The fastener 112 is detachably connected to the connection member 111. When the connecting piece 111 is properly positioned in the through groove 109, the mounting frame 110 and the fixing frame 104 can be relatively and fixedly connected by using the fastening piece 112. As illustrated in the example, 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 is 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 blocking block 115, and the blocking block 115 is located on a moving path of the fixing frame 104 and is used for blocking the fixing frame 104 to limit a moving distance of the fixing frame 104.
