Fig. 1 is a schematic perspective view of the present utility model.
Fig. 2 is a schematic top view of the present utility model in operation.
As shown in the figure: 1. the device comprises a base, 2, a vertical plate, 3, a flat plate, 4, a rib plate, 5, a positioning block, 6, a sliding plate, 7, a pin shaft, 8, a bolt, 9, a mounting hole, 10 and a workpiece.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, a parallelogram synchronous adjusting and positioning mechanism consists of a base 1, two vertical plates 2, a flat plate 3, a rib plate 4, two positioning blocks 5, a sliding plate 6, two pin shafts 7 and two bolts 8.
The two vertical plates 2 are welded on the upper side of the base 1 and are oppositely arranged, the flat plate 3 is welded on the upper ends of the two vertical plates 2, the rib plate 4 is welded between the two vertical plates 2, the lower ends of the rib plates are welded with the base 1, and the rib plate 4 plays a role in reinforcing and connecting the positioning mechanism; the flat plate 3 and the positioning blocks 5 are provided with pin holes, and the pin holes on the positioning blocks 5 are arranged at the center positions of the positioning blocks 5, so that when the two positioning blocks 5 rotate, the sizes of the two positioning blocks 5 can be adjusted to be consistent; screw holes are formed in two ends of the flat plate 3 and the sliding plate 6, bolts 8 are installed in the screw holes, the sliding plate 6 is connected between the two positioning blocks 5, and the two pin holes and the two screw holes are combined together to form a parallelogram, so that synchronous rotation of the two positioning blocks 5 can be realized; the base 1 and the vertical plate 2 and the flat plate 3 are welded together, so that the firmness of the positioning mechanism is enhanced, and a plurality of mounting holes 9 are uniformly formed in the base 1, so that the positioning mechanism is convenient to mount and fix.
When the positioning mechanism is used, the positioning mechanism is arranged on a workbench surface through the mounting holes 9, before positioning, the two bolts 8 are in a loose state, the positioning blocks 5 and the sliding plate 6 can relatively rotate, then one of the positioning blocks 5 is rotated, the other positioning block 5 is simultaneously driven to synchronously rotate through the matching of the sliding plate 6, and the positioning size of the two positioning blocks 5 is adjusted to be smaller than the inner gear size of the workpiece 10, so that the workpiece 10 is conveniently placed in;
