Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1 to 5, the present embodiment provides an opening and closing mechanism for a testing fixture, which includes a substrate 1, an actuating component and a control component.
The action subassembly is including opening and shutting base 2, first piece 3 and the second piece 4 that opens and shuts of opening and shutting, the base 2 that opens and shuts is fixed in the upper surface of base plate 1, first piece 3 that opens and shuts, second piece 4 that opens and shuts rotates respectively to be connected on opening and shutting base 2 and cooperate the butt clamp, be provided with first crosspiece 5 on the first piece 3 that opens and shuts, the second is opened and shut and is provided with second crosspiece 6 on the piece 4, first crosspiece 5 and 6 upper and lower interval arrangements of second crosspiece are pressed from both sides and are equipped with spring 7 between, interval through the vertical two crosspiece of adjusting of control assembly, and then change the interval of two pieces that open and shut. The first crosspiece 5 passes through the second opening and closing sheet 4, and the second opening and closing sheet 4 is provided with a abdicating groove. The crosspiece can be made into a whole with the opening and closing sheet or can be fixed on the opening and closing sheet as a separated piece.
The control assembly comprises a cylinder 8, a fixed plate 9, a movable plate 10 and a brake cable 11, wherein the cylinder 8 is fixed on the lower surface of the substrate 1, the output end of the cylinder 8 faces downwards, the fixed plate 9 is fixed on the cylinder body of the cylinder 8, the movable plate 10 is connected with an output rod of the cylinder 8, so that the movable plate 10 can move relative to the fixed plate 9, one end of the brake cable 11 is fixed on the movable plate 10, an internal steel wire penetrates through the movable plate 10 to be fixed on the fixed plate 9, the other end of the brake cable 11 is fixed on the second crosspiece 6, the internal steel wire penetrates through the second crosspiece 6 to be fixed on the first crosspiece 5, and particularly, the spring.
