Due to the arrangement of the anti-rotation locking ribs 131 and the anti-rotation locking grooves 26, not only can the pre-adjustment of the adjusting gasket be achieved, but also the effect of placing the adjusting gasket to rotate unexpectedly can be achieved after the adjusting gasket is assembled.
The use of the spacer of the present invention is briefly described below.
As shown in fig. 1, 4 and 5, in the actual assembly process, the adjusting shim is fixed on the first part 5, and then the second part 6 is inserted into the bolt 4 to be tightened, but the bolt 4 is not required to be completely tightened, and only the second part 6 needs to be approximately fixed. And (3) rotating the quick adjustment movable piece 1 by using the adjustment tool 7 until the second part 6 reaches a proper position, and pre-tightening the bolt 4 as required. When the bolt 4 needs to be adjusted after being pre-tightened, the bolt 4 needs to be slightly loosened, the height of the gasket is adjusted by using the adjusting tool 7, and the bolt 4 needs to be pre-tightened again after the second part 6 reaches a proper position.
Specifically, when the adjusting shim needs to be adjusted, the head of the adjusting tool 7 is inserted into the pattern 14 of the adjusting rotor and rotated, at the moment, the anti-rotation locking rib 131 can cross the anti-rotation locking groove 26 under the action of external force, and the height of the adjusting shim is changed under the action of the interlocking hook 13 of the adjusting rotor 1 and the adjusting stator 2, so that the gap and the surface difference of parts can be adjusted. When the adjusting shim is not assembled, the adjusting moving plate 1 can be manually rotated to complete adjustment. During the period, the spring 3 can play a role of separating the adjusting movable plate 1 and the adjusting static plate 2, so that the adjusting movable plate 1 and the adjusting static plate 2 are always separated under the free state of the adjusting gasket, and the height of the adjusting gasket is convenient to adjust.
When a large amount of shims are adjusted, an adjusting tool is required to be used for adjustment every time, so that the working efficiency is seriously influenced, and the shims can be pre-adjusted. Firstly, the distance between parts in the same batch of parts needs to be known through a measuring or experimental method, and the adjusting shim is adjusted to a proper position in advance, so that each part does not need to be adjusted when large-batch operation is completed, and the working efficiency is improved.
In summary, the adjusting shim of the utility model can rapidly adjust the clearance and the surface difference of the parts without disassembling the parts in a certain range, and can realize high-precision rapid adjustment; not only the size chain transmission between the parts is interrupted, but also the tolerance requirement of the matching surface of the two parts can be reduced, thereby greatly saving the cost; one gasket can be quickly switched to have various thicknesses, so that the problems of repeated assembly and disassembly of parts and large-batch preparation of gaskets with different thicknesses are solved, the material cost is saved, and the working efficiency is improved; the injection molding can be carried out by engineering plastics in an integrated manner, and the injection molding can also be formed by machining metal materials, so that the structure is simple and the manufacture is convenient; the risk of moment attenuation between parts can be reduced by adopting a specific structure, the pre-adjustment of the gasket is realized, and the parts are prevented from rotating accidentally after being assembled; the door handle can be suitable for engineering technical scenes such as automobiles, aerospace, machining and the like, and the situation that the surface difference between the hidden door handle and a metal plate is not perfectly matched in the actual automobile manufacturing process can be realized. Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
