Detailed Description
Example one
Referring to fig. 1-9, the present invention provides a technical solution:
a midpoint punching positioner is characterized in that when the midpoint punching positioner is used, rectangular pipes such as aluminum pipes and square aluminum pipes are horizontally placed, the distance between two groups of clamping plates 2 is changed by rotating an adjusting handle 4, the left and right sides of the pipes are clamped by the two groups of clamping plates 2, the tip end of a positioning needle 1 is in contact with the pipes, a certain gap exists between a hammering surface above the positioning needle 1 and an adjusting shaft 6, the positioning needle 1 can move downwards after the pipes are removed, and a hammer is used for tapping the hammering surface above the positioning needle 1 to complete midpoint positioning holes;
the surface of the positioning needle 1 is sleeved with a threaded sleeve rod 3, the top end of the threaded sleeve rod 3 is fixedly connected with an adjusting handle 4, and the adjusting handle 4 and the threaded sleeve rod 3 are of an integrated structure, so that when a user manually rotates the adjusting handle 4, the threaded sleeve rod 3 can rotate on the surface of the positioning needle 1;
meanwhile, the lower end surface of the threaded sleeve rod 3 is provided with threads, and the upper end surface of the threaded sleeve rod 3 is smooth;
the upper smooth surface of the threaded sleeve rod 3 is sleeved with an adjusting shaft 6, the inner surface of a hole in the vertical direction of the shaft of the adjusting shaft 6 is smooth, the lower threaded surface of the threaded sleeve rod 3 is sleeved with a positioning shaft 7, the inner surface of the hole in the vertical direction of the positioning shaft 7 is provided with an internal thread matched with the thread on the threaded sleeve rod 3, after the threaded sleeve rod 3 passes through the adjusting shaft 6 and the positioning shaft 7, the limiting ring 5 is used for preventing the relative movement between the adjusting shaft 6 and the threaded sleeve rod 3, a through hole is formed in the vertical direction of the threaded sleeve rod 3, the hole just accommodates a positioning needle 1 to pass through, and the positioning needle 1 is vertically inserted into the threaded sleeve rod 3;
six rotating shaft bases 8 are fixed on the clamping plate 2 on each side, three groups of rotating shaft bases are arranged on the surface of one side of the clamping plate 2, the rotating shaft bases 8 in the uppermost row and the rotating shaft bases in the lowermost row are vertically arranged, and the rotating shaft bases 8 in the middle row are transversely arranged;
an upper connecting rod 9 is hinged in the uppermost row of rotating shaft base 8, and four groups of upper connecting rods 9 on the two groups of clamping plates 2 are hinged on the adjusting shaft 6 through bolts;
a transverse connecting rod 10 is hinged in the middle row of rotating shaft bases 8, and four groups of transverse connecting rods 10 on the two groups of clamping plates 2 are hinged together through bolts;
the lower connecting rods 11 are hinged in the rotating shaft base 8 at the lowest row, and the four groups of lower connecting rods 11 on the two groups of clamping plates 2 are hinged on the positioning shaft 7 through bolts;
the four groups of upper connecting rods 9 and the four groups of lower connecting rods 11 are completely consistent in length and shape, and the four groups of transverse connecting rods 10 are completely consistent in length and shape;
therefore, when the user rotates the adjusting handle 4 and is connected the threaded sleeve rod 3 and rotates on the surface of the positioning needle 1, the adjusting shaft 6 is limited by the limiting ring 5, the adjusting shaft 6 cannot slide on the threaded sleeve rod 3, and the positioning shaft 7 is movably connected with the clamp plates 2 through the four groups of lower connecting rods 11, so that the positioning shaft 7 can slide up and down on the surface of the threaded sleeve rod 3, the positioning shaft 7 can drive the four groups of lower connecting rods 11 to rotate and change included angles in the sliding process, meanwhile, the included angles between the four groups of upper connecting rods 9 and the transverse connecting rods 10 can also change along with the rotation, so that the intervals of the two groups of clamp plates 2 are adjusted, the clamp plates 2 can be clamped on the surface of a rectangular pipe, the positioning needle 1 is always located at the central position of the two groups of clamp plates 2, and midpoint punching is realized.
