Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example 1
As shown in fig. 1 to 3, the utility model relates to a flexible aluminum alloy ex-trusions of high accuracy, including upper and lower penetrating square pipe 1, every side of square pipe 1 all is equipped with a plurality of finishing fixed orificess 2 that are used for wearing to establish axial connecting piece (not mark), 2 arrays of finishing fixed orifices are arranged and the distance between the adjacent finishing fixed orificess 2 equals, and square pipe 1's side inner wall still is equipped with and is located adjacent two strengthening rib 3 between 2 finishing fixed orificess, and strengthening rib 3 is equipped with the groove 31 of dodging that is used for dodging axial connecting piece. In practice, a plurality of identical aluminium alloy sections are used, which are fixed in parallel or perpendicular relationship by finishing the fixing holes 2. The fine-trimming fixing hole 2 serves as a connecting position between the square pipe 1 and also serves as a fixing position of the checking fixture and the fixture, the built specific structure can be changed randomly according to requirements, and the small part can be disassembled to be stored when the device is not used. The reinforcing ribs 3 can reinforce the structure of the square pipe 1, but prevent blocking of the installation of the shaft-shaped coupler by avoiding the grooves 31. So the utility model discloses can freely build the foundation structure who examines utensil, anchor clamps, can realize that the flexibility changes and the fast switch-over dismouting.
As shown in fig. 1 and 2, two rows of finishing fixing holes 2 are arranged on each side surface, and the number of the rows can reach more than ten. When the two square pipes 1 need to be vertically fixed, at least four pairs of finishing fixing holes 2 which are distributed in a square shape can be used for connection, so that the stability of the building structure can be ensured.
As shown in fig. 2 and 3, the distance between the centers of the adjacent finishing fixing holes 2 is equal to two times 2D of the inner diameter of the finishing fixing hole 2, and the distance between the center of the next row of finishing fixing holes 2 and the adjacent side surface is equal to the inner diameter D of the finishing fixing hole 2. Set up like this and make the width of side must be the quadruple 4D of 2 internal diameters of truing fixed orifices, when square pipe 1 installs side by side moreover, the interval of adjacent a list of truing fixed orifices 2 still keeps the distance of two 2 internal diameters of truing fixed orifices, need not measure again.
As shown in fig. 2, the distance from the center of the reinforcing bead 3 to the nearest adjacent side is equal to two times 2D of the inner diameter of the finishing fixing hole 2. That is to say, the position of the reinforcing rib 3 is located at the central position of the two rows of the finishing fixing holes 2, so that a better supporting effect can be achieved.
As shown in fig. 3, a stepped slot 11 is provided in the end of the square tube 1 for assembling an end cap (not shown), and the distance from the center of the row of fine fixing holes to the end face is equal to the inner diameter D of the fine fixing hole 2. Need add the end cover when two square pipes 1 want sharp connection to realize, then will play the positioning action through the installation end cover on the step draw-in groove 11, and connect the back, the nearest distance of finishing fixed orifices 2 still 2D on the square pipe 1 of front and back, need not measure again.
As shown in fig. 2, both sides of the finishing fixing hole 2 are provided with chamfers 21. In order to enable the dimensional accuracy of the building structure to meet the requirements, the machining accuracy of the fine trimming fixing hole 2, the chamfer 21 and the step clamping groove 11 needs to be H8 level, and the accuracy of the assembled body can reach the position accuracy of the checking fixture and the clamp.
Example 2
As shown in fig. 4, the difference from embodiment 1 is that: three rows of finishing fixing holes 2 are arranged on each side surface. For a slightly larger frame structure, the principle of use is unchanged, whereas the structure of the square tube 1 can be made larger.
As shown in fig. 4, the distance between the centers of the adjacent finishing fixing holes 2 is equal to two times 2D of the inner diameter of the finishing fixing hole 2, and the distance from the center of the next row of finishing fixing holes 2 to the adjacent side is equal to the inner diameter D of the finishing fixing hole 2. Set up like this and make the width of side must be the six times 6D of 2 internal diameters of truing the fixed orifices, when square pipe 1 was installed side by side moreover, the interval of 2 adjacent truing fixed orifices still keeps the distance of 2 internal diameters of two truing fixed orifices, need not measure again.
As shown in fig. 4, the distance from the center of the reinforcing bead 3 to the nearest adjacent side is equal to two times 2D of the inner diameter of the finishing fixing hole 2. That is to say, the position of the reinforcing rib 3 is located at the central position of the two rows of the finishing fixing holes 2, so that a better supporting effect can be achieved.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
