detailed description

As shown in Figures 1 and 2, a processing jig for the inner cavity of a mobile phone frame includes a jig base plate 1, and a first support arm 2 and a second support arm 3 are connected to the left and right sides of the lower surface of the jig base plate 1. A supporting arm 2 and a positioning pin 4 are arranged on the upper surface of the second supporting arm 3 respectively, and a positioning pin hole is opened on the jig bottom plate 1 and cooperates with the positioning pin 4 on the supporting arm. The jig bottom plate 1 and the first supporting arm 2 and the second support arm 3 are fixedly connected by bolts. A body 5 is placed on the upper surface of the jig bottom plate 1. The body 5 is a cuboid structure. The upper surfaces on both sides of the center of the body 5 are connected with third positioning pins 6. The center of the body 5 Bolts 7 are connected to the upper surfaces on both sides close to the third positioning pin 6, cylinder pressure claws 8 are respectively arranged above the four corners of the body 5, and the cylinder pressure claws 8 are connected to the first cylinder 9, the first cylinder 9 It is fixedly connected with the lower surface of the fixture bottom plate 1. The first cylinder 9 and the fixture bottom plate 1 are connected by bolts. This connection method is firm and detachable, and it is very convenient to use. The fixture bottom plate 1 on the left side of the body The first positioning pin 10 is arranged on the top, and the first positioning pin 10 is attached to the left side of the main body 5.
