Drawings
Fig. 1 is a schematic structural diagram of a dual plug pin device according to an embodiment of the present invention;
in the figure, a 1-movable bayonet lock, a 2-base, a 3-pressing pin pulling plate, a 4-connecting rod I, a 5-hand deflector rod, a 6-connecting rod II, a 7-support, an 8-return spring, a 9-flange, a 10-lug, an 11-free part and a 12-connecting part are arranged.
Detailed Description
To describe the technical contents, the achieved objects and effects of the present invention in detail, the following description is made with reference to the embodiments in conjunction with the accompanying drawings.
Example 1
Referring to fig. 1, a dual plug pin device includes a base 2, a push pin plate 3, a connecting rod i 4, a connecting rod ii 6, a support 7, a movable bayonet 1, and a return spring 8, wherein a lug 10 is provided at the top of the base 2;
the side surface of the base 2 is provided with a support 7, the shape of the support 7 is 'gamma', and the vertical end of the support 7 is connected with the side surface of the base 2; one end of the pressing pin pulling plate 3 is movably connected with the lug 10, the other end of the pressing pin pulling plate 3 is movably connected with one end of the connecting rod I4, the other end of the connecting rod I4 is movably connected with one end of the connecting rod II 6, and the horizontal end of the support 7 is movably connected with the middle part of the connecting rod II 6;
the movable bayonet lock 1 is the shaft-like, the movable bayonet lock 1 includes free portion 11, connecting portion 12 to and flange 9 that the middle part set up, the connecting portion 12 of movable bayonet lock 1 is worn out from the side that is connected with support 7 on the base 2, and with the other end swing joint of connecting rod II 6, reset spring 8 cover is established on the movable bayonet lock 1, reset spring 8 one end is connected with base 2, and its other end links to each other with flange 9 of movable bayonet lock 1, still be provided with hand driving lever 5 on the connecting rod II 6.
As shown in fig. 1, in the assembly process, when an operator stands on a part with a higher assembly position, the free part 11 of the movable bayonet lock 1 is used for clamping a tray, when the tray needs to be rotated, the operator does not need to bend down and steps on the push-pull pin plate 3, at the moment, the push-pull pin plate 3 is movably connected with the connecting rod i 4, at the moment, the push-pull pin plate 3 pulls the connecting rod i 4 to move downwards, the connecting rod i 4 drives the connecting rod ii 6 to rotate leftwards, the lower end of the connecting rod ii 6 drags the connecting part 12 of the movable bayonet lock 1 to move rightwards, so that the movable bayonet lock 1 moves rightwards to be separated from the tray, the tray is not clamped any more, the tray can be freely rotated, and when the tray rotates to the installation position, the operator can loosen the foot of the push-pull pin plate 3, and the movable bayonet lock 1 moves leftwards to clamp the tray due to the action of the reset spring 8. When the assembly position of the parts is lower, due to the general squatting and bending assembly operation of an operator, the operator can grasp the hand lever 5 when the tray needs to be rotated, the connecting rod II 6 rotates anticlockwise, the connecting rod II 6 pulls the movable bayonet lock 1 to move rightwards to be separated from the tray, the tray can rotate freely, the operator releases the hand lever 5 when the tray rotates to the assembly position, and the movable bayonet lock 1 moves leftwards to clamp the tray under the action of the elastic force of the reset spring 8. Therefore, the device can provide two pin pulling modes, can be used for pulling pins by hands and can also be used for stepping on the pins, so that the problem of pin turning compatibility of the pins in different procedures in the assembly process of the engine is solved, the labor intensity is reduced, and the production efficiency is improved.
