Detailed Description
Example one
As shown in fig. 1, a floating support structure for straightening long bars comprises two parallel guide rails 2 fixedly arranged on a support frame body 1, and a support block 3 with a T-shaped cross section is arranged between the two guide rails 2.
For convenience of description, the supporting block 3 is now divided into a horizontal portion and a vertical portion.
The horizontal part is positioned above the guide rails 2, and the vertical part is positioned between the two guide rails 2 and is matched with the guide rails 2 to realize the guiding movement of the supporting block 3 along the length direction of the guide rails 2.
As shown in fig. 1, at least two sets of floating support assemblies 4 are respectively disposed between the horizontal portion of the support block 3 and the guide rail 2 at two sides of the vertical portion of the support block 3.
As a specific implementation manner, in this embodiment, two groups of floating support assemblies 4 are respectively disposed between the horizontal portion of the support block 3 and the guide rail 2 and located on two sides of the vertical portion of the support block 3, and the four groups of floating support assemblies 4 are arranged in a matrix of two rows and two columns.
As shown in fig. 2, a mounting hole with a blind upper end is formed on the lower side of the horizontal portion of the supporting block 3, and the floating supporting member 4 is disposed in the mounting hole. The floating support assembly 4 includes an elastic member and a mounting block 41 in sequence from top to bottom, and as a specific embodiment, the elastic member is a disc spring 44 in this embodiment.
The lower side surface of the mounting block 41 is provided with a mounting groove, a rolling member is arranged in the mounting groove, and the rolling member protrudes out of the lower side surface of the horizontal part of the supporting block 3 under the action of the disc spring 44 in a free state. In one embodiment, the rolling member is a bearing 42. Preferably, the bearing 42 is a cylindrical roller bearing 42. The bearing 42 is rotatably connected with the mounting block 41 through a pin shaft 43. As a specific implementation manner, in this embodiment, the inner ring of the bearing 42 is tightly connected with the pin 43 by interference fit, and the pin 43 is fixedly connected with the mounting block 41 by a set screw 46.
Here, the free state refers to a state in which the straightening machine does not perform the straightening operation and the supporting block 3 is only subjected to the weight of the bar 5.
When the bar 5 is straightened, the pressure head 6 of the straightening machine moves downwards to press the bar 5, the disc spring 44 of the floating support component 4 is compressed, the support block 3 moves downwards to drive the bar 5 on the support block 3 to move downwards until the lower side surface of the horizontal part of the support block 3 presses the guide rail 2. The bearing 42 is now pressed completely into the mounting hole and the support block 3 carries the pressure from the straightener instead of the bearing 42. The pressing head 6 of the straightening machine continues to move downwards, and the supporting block 3 does not move downwards at the moment and is in a fixed state, so that the bar 5 deforms under the action of the straightening machine, and the bar 5 is straightened.
Further, in order to prevent the support assembly from falling off the support block 3 when the support block 3 is separated from the guide rail 2, as shown in fig. 2, a guide limit screw 45 is disposed on a side wall of a horizontal portion of the support block 3, a vertical sliding groove matched with the guide limit screw 45 is disposed on a side wall of the mounting block 41, and the guide limit screw 45 and the vertical sliding groove jointly determine a lower limit position of the mounting block 41 relative to the support block 3.
Further, as shown in fig. 3, the horizontal section of the mounting block 41 is circular.
Further, as shown in fig. 2, a central shaft 411 is disposed on an upper side surface of the mounting block 41 and is coaxial with the mounting block 41, and the disc spring 44 is sleeved outside the central shaft 411. Correspondingly, the blind end of the mounting hole is provided with a avoiding hole for accommodating the central shaft 411, and the mounting hole and the avoiding hole jointly form a step hole.
Example two
The rolling part is a roller, the roller is rotatably connected with the pin shaft 43 through a bearing 42 assembly, and the rest of the structure is the same as that of the first embodiment.
