[0013] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0014] like Figure 1-2 As shown, a bottom plate line positioning flexible switching mechanism includes a base 1, a rotating cylinder 2, a mounting seat 3, a hinge shaft 4, a rotating plate 5, a first hook pin cylinder 6, a second hook pin cylinder 7 and a locking cylinder 8. The piston rod of the rotating cylinder is hinged to one end of the rotating plate, the rotating cylinder is hinged to one end of the cylinder connecting plate, the cylinder connecting plate is fixed to the side of the base, the cylinder connecting plates are divided into two pieces, which are respectively fixed on both sides of the base, and the two cylinder connecting plates are hinged to the cylinder body of the rotating cylinder through a pin shaft.
[0015] In order to support the upper component, a bottom plate 9 is fixed on the upper part of the base, and two mounting seats are fixed on the bottom plate. The rotating plate is hinged to the upper parts of the two mounting seats through the hinge shaft, and the rotating plate can rotate through the hinge shaft. In order to limit the rotating plate, as shown in FIG. Figure 2 As shown, Figure 2 This is an internal schematic diagram with a mounting seat removed. In order to limit the rotation angle of the rotating plate, a vertical plate 10 is fixed on the base, fixed stops 11 are fixed on both sides of the vertical plate, and a movable stop 12 is fixed on the inner side of the rotating plate. The movable stop contacts and cooperates with the fixed stop. When the two movable stops fit to the position of the fixed stop, they are blocked and stop rotating further.
[0016] In order to position the rotating plate, the locking cylinder is fixed to the base plate through a locking cylinder support plate. Two bushings are provided on the rotating plate. A positioning pin is installed on the piston rod of the locking cylinder. The positioning pin is plugged into the bushing. The two bushings correspond to the switching of two vehicle models.
[0017] The first hook pin cylinder and the second hook pin cylinder are respectively fixed to the rotating plate through connecting plates. The shape and structure of the connecting plates can be adjusted according to the position of a specific vehicle model. Positioning pins are installed on the piston rods of the first hook pin and the second hook pin.
[0018] In order to detect the position of the rotating plate, proximity switches 13 are provided on both sides of the bottom plate.
[0019] In order to enable the positioning pin to move smoothly, a positioning sleeve 14 is provided on the locking cylinder.
[0020] Specific operations:
[0021] like Figure 3 As shown, when producing a certain type of vehicle, the first detent cylinder needs to be flipped to the working position, and the second detent cylinder needs to be flipped to the safe waiting position.
[0022] The specific actions are controlled by PLC: the pull rod cylinder of the rotating cylinder extends to drive the rotating plate to rotate, the first hook pin cylinder and the second hook pin cylinder flip over, the first hook pin cylinder flips forward, the movable stop block fits with the fixed stop block, the proximity switch has a signal, and then the locking cylinder drives the locking pin to insert the bushing to lock the rotating plate and complete the vehicle model switching.
[0023] like Figure 4 As shown, when producing another model, the second detent cylinder needs to be turned to the working position and the first detent cylinder needs to be turned to the safe waiting position. The rotating cylinder is retracted, which is opposite to the movement direction of the first model.
[0024] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
