Description
Technical Field
The utility model belongs to the technical field of coupling mechanism between the mechanical parts, concretely relates to a coupling mechanism that is used for being connected between back operating system bottom plate and the layering.
Background
The amphibious vehicle rear lifting system comprises a base plate 1 and a batten 3, as shown in figures 1 to 5. This L template of bottom plate 1 is equipped with circular installation hole site and bolt hole on every side on the short sideboard of L template, is equipped with the through-hole along the central line interval on the long sideboard of L template, and the central line both sides all are equipped with boss 2 that is used for the installation location, and boss 2 is the rectangle boss, and length is 670mm, and the width is 5mm, highly is 4mm, and the interval is equipped with the installation screw on the boss 2, and the long sideboard both sides of L template are equipped with the bolt hole. The layering 3 includes left and right two layering, is equipped with on the layering 3 with boss 2 complex recess 4, recess 4 length be 670mm, and the width is 5mm, correspond on the recess 4 to be equipped with boss 2 on the installation screw correspond the complex installation screw. The connecting mechanism between the base plate 1 and the pressing strip 3 is formed by the lug boss 2 and the groove 4.
In the actual processing process of the base plate 1, as the boss 2 is longer in length and narrower in width, and the base plate 1 is thinner, after the base plate 1 is processed, the base plate 1 and the boss 2 are more or less deformed. In the actual processing process of the pressing strip 3, the length of the groove 4 is longer, the width of the groove is narrower, and the pressing strip 3 is thinner, so that the pressing strip 3 and the groove 4 are deformed more or less. Because the boss 2 and the groove 4 are closed connecting mechanisms and have no adjusting positions, once the boss 2 and the groove 4 are not matched, if the size is not proper, the sliding surface can be corrected by grinding the sliding surface, but after the correction is finished, the size of the position of the sliding surface and the position of the groove 4 are not matched with the requirement and are not matched with the boss 2, and the installation and the connection cannot be carried out. In addition, the groove 4 requires the plane parallelism difference 2 threads between the slideway surface and the pressing strip 3, and two modes are provided if the processing is carried out by utilizing the prior technical conditions: one mode is hard milling, and a cutter with the diameter of 5mm is adopted, so that the size of the hard milling cutter is not easy to guarantee after the cutter is abraded; another way is flat grinding, which must use a grinding wheel less than 5mm, and if the grinding wheel is 20mm thick, it must be trimmed to 5mm thick, the grinding wheel falls off very quickly during the groove grinding process, which causes the dimensions of the two ends of the groove to be inconsistent, and the cost of the 20mm thick grinding wheel is also high.
The existing bottom plate 1 and the pressing strip 3 have the problem of high processing difficulty, and the boss 2 and the groove 4 do not have adjustability, so that the final assembly size precision is influenced.
Disclosure of Invention
The utility model aims at providing a coupling mechanism of back operating system bottom plate and layering to above-mentioned weak point for the erection joint of bottom plate and layering.
The technical solution of utility model is: the utility model provides a coupling mechanism of back operating system bottom plate and layering, includes bottom plate and layering, parallel arrangement has two bar bosss on the bottom plate, the layering has two, corresponds cooperation, its characterized in that with two bar bosss on the bottom plate respectively: and a notch is arranged at the part of the pressing strip corresponding to the lug boss.
The technical proposal of the utility model is that the notch is a rectangular groove-shaped notch composed of a bottom surface and a side surface; one side surface of the notch is matched with the outer side surface of the boss on the bottom plate.
The technical solution of the utility model in the length of boss be 670mm, the width is 8mm.
The technical solution of the utility model is that the height of a side face of the notch is the same as the height of the boss.
The utility model discloses because on the basis of current bottom plate and two layering, only be equipped with the breach with the position that the boss corresponds on two layering, be about to the layering and go up former recess and change into the side form of opening into, therefore after the processing of completion bottom plate and two layering, if the unmatched time appears, can grind the side of breach promptly the slideway face, how much the slideway face grinds, how much in the past just can be moved to the slideway face, can guarantee breach and boss matching. In addition, because the notch is a through groove, the grinding wheel with more width can be ground, and both sides of the grinding wheel can be ground, so that the size can be ensured, and the grinding machine is convenient; if milling is required, the milling is simpler and is performed in the past.
The utility model has the characteristics of simple structure, assembly have the adjustability and reduce the processing cost, mainly used amphibious car back operating system bottom plate is connected with the erection joint of layering.

Detailed Description
The following detailed description will be made with reference to the accompanying drawings.
As shown in fig. 1-2 and fig. 6-7, an embodiment of the connecting mechanism for the bottom plate and the pressing bar of the rear lifting system of the present invention comprises a bottom plate 1 and a pressing bar 5. The base plate 1 is the same as the conventional base plate 1 except that the width of the bosses 2 is different. The bead 5 is identical to the existing bead 3 except for the notch 6.
Two strip-shaped bosses 2 are arranged on the bottom plate 1 in parallel, the length of each boss 2 is 670mm, and the width of each boss is 8mm. Because the gap 6 is arranged on the pressing strip 5 to be matched with the boss 2, and the gap 6 is a through groove, the width of 5mm of the existing boss 2 can be increased to 8mm without changing the overall dimension of the pressing strip 5, so that the boss 2 is easy to process, and the deformation of the boss 2 is greatly reduced.
The number of the pressing strips 5 is two, and the two pressing strips are respectively matched with the two strip-shaped bosses 2 on the bottom plate 1 correspondingly. The part of the pressing strip 5 corresponding to the boss 2 is provided with a notch 6, the notch 6 is a rectangular groove-shaped notch formed by the bottom surface and one side surface, one side surface of the notch 6 is matched with the outer side surface of the boss 2 on the base plate 1, and the height of one side surface of the notch 6 is the same as that of the boss 2. The notch 6 is much less difficult to machine than the groove 4.
The adjustment is more flexible and convenient, and when the lug boss 2 is not properly assembled with the notch 6, the adjustment can be carried out on the sliding way surface and the positioning surface. The size of the slide way surface of the notch 6 can be adjusted freely according to the size of the slide way surface of the notch 6 in the past by grinding the step surface of the slide way of the notch 6, and the step surface is developed, so that the grinding wheel with large width can be ground without being limited by the thickness of the grinding wheel. The size can both be guaranteed, the assembly precision of the gap 0.05 can be accurately achieved, and the device is not restricted and can be adjusted according to the situation. If the milling is carried out, the milling is simpler, the milling is carried out in the past, and the milling is more precise.
