The base body 1 can be a large platform of a mother machine or a small platform of a son machine of the scissor lift machine, and can also be an equipment base of the scissor lift machine. The base body 1 is provided with a convex part 1-1.
The positioning adjusting device comprises a body 5, a mandrel 2, a distance ruler 6, a cross slide rail 9, a parallelogram mechanism 10 and a left group and a right group of hook plates 8.
The rear end of the distance rod 6 is used for being in contact with the boss 1-1, the front end of the distance rod 6 penetrates through the sliding groove in the body 5, and the body 5 is provided with a locking screw 7 used for locking the distance rod 6. The distance scale 6 is used for determining the distance between the body 5 and the boss 1-1. Preferably, the distance rods 6 are arranged in two parallel groups, and the rear ends of the two groups are connected through a connecting plate, so that the parallelism between the convex part 1-1 and the body 5 is ensured.
The left side and the right side of the body 5 are respectively provided with an installation sleeve for installing the mandrel 2. The mandrel 2 is used for matching the inner hole of the hinged support 3. Normally, two hinge bases 3 are required to be mounted on the mandrel 2 on each side, and therefore, distance sleeves 4 are further arranged on the mandrel 2 and are arranged between the adjacent hinge bases 3. When the free bearing 3 is installed, the free bearing 3 close to the inner end is tightly attached to the end part of the installation sleeve of the body 5, and the two ends of the distance sleeve 4 are tightly attached to the free bearing 3 at the two sides, so that the free bearing 3 is accurately positioned relative to the body 5.
The front end of the body 5 is rotatably connected with the middle part of the cross slide rail 9 through an M12X35 external hexagonal bolt and nut.
The parallelogram mechanism 10 comprises four connecting rods 10-1 which are sequentially connected end to end, and the connecting rods 10-1 are rotatably connected through a reamed hole bolt 10-2 of M8X45, a spacer and a non-metal insert self-locking nut.
The cross slide rail 9 is provided with a longitudinal slide rail (Y direction in the figure) and a transverse slide rail (X direction in the figure). The front and the back two hinged hole bolts 10-2 of the parallelogram mechanism 10 are matched with the longitudinal slide rail of the cross slide rail 9, the left and the right two hinged hole bolts 10-2 of the parallelogram mechanism 10 are matched with the transverse slide rail of the cross slide rail 9, and the corresponding spacers and the non-metal insert self-locking nuts are positioned above the cross slide rail 9.
