Abstract
The utility model belongs to the mechanical design field relates to an articulated bolt. The hinge bolt is of an integral structure and sequentially comprises a bolt head (1), a polished rod (3) and a threaded area (4), wherein an anti-rotation pin (2) is arranged on the bolt head (1), and two cotter pin through holes (5) are arranged on the threaded area (4); through the hinge bolt, the rotation abrasion of the bolt is avoided, the hinge reliability is improved, and the split pin is easy to install under the condition of meeting the requirement of tightening torque.
Description
Technical Field
The invention belongs to the field of mechanical design and relates to a hinge bolt.
Background
The articulated form is a typical form of mechanical design articulated connection, see fig. 1, the articulated joint is provided with an articulated bearing, a mutual motion exists between the double-lug support 7 and the moving mechanism 8 in fig. 1, and in addition, due to factors such as vibration and the like existing in an actual working environment, the articulated bolt rotates around a shaft in work. The rotation can bring the wearing and tearing of hinge bolt, can lead to the hinge failure even for a long time, influences the hinge reliability. In addition, the hinge bolt generally needs moment to be tightened when being installed, and the conventional bolt generally only has one split pin hole, so when the moment meets the requirement in the tightening process, the split pin hole is easily shielded by the nut 9, and the split pin 6 cannot be installed, so that inconvenience is brought to the installation, and the tightening moment requirement cannot be guaranteed.
Disclosure of Invention
The purpose of the invention is: the hinge bolt is designed, so that the rotary abrasion of the hinge bolt can be effectively avoided, and the split pin can be easily installed under the condition of meeting the requirement of tightening torque.
The technical scheme of the invention is as follows: the utility model provides an articulated bolt, its characterized in that, articulated bolt is overall structure, is bolt head 1, polished rod 3, and threaded area 4 triplex in proper order, is provided with on the bolt head 1 and prevents that the round pin 2 is provided with two split pin through-holes 5 on the threaded area 4.
The two cotter pin through holes 5 are vertical in axis, so that the bolt is prevented from rotating.
The height of the anti-rotation pin 2 is smaller than the thickness of a single lug of the double-lug support 7, and assembly is convenient.
The parameters of the anti-rotation pin 2 are determined by the nut tightening torque to prevent the screw from being broken.
The anti-rotation pins 2 are in clearance fit with anti-rotation pin holes in the double-lug support 7.
The bolt head 1 is of a hexagonal structure.
The invention has the following beneficial effects: through the hinge bolt, the rotation abrasion of the bolt is avoided, the hinge reliability is improved, and the split pin is easy to install under the condition of meeting the requirement of tightening torque.
Drawings
FIG. 1 is a schematic view of a hinged installation; the device comprises a hinge bolt 1, a double-lug support 2, a motion mechanism 3, a hinge bolt 4, a nut 5 and a cotter pin 6.
Fig. 2 is a schematic view of a hinge bolt.
FIG. 3 is a schematic view of an embodiment of a hinge bolt; the device comprises a hinge bolt 1, a double-lug support 7, a movement mechanism 8, a cotter pin 6 and a nut 9.
Detailed Description
The invention is described in further detail below with reference to the drawings.
As shown in fig. 2, the hinge bolt is of an integral structure and sequentially comprises a bolt head 1, a polished rod 3 and a threaded area 4, wherein an anti-rotation pin 2 is arranged on the bolt head 1, and two cotter pin through holes 5 are arranged on the threaded area 4; the two cotter pin through holes 5 are vertical in axis to prevent the bolt from rotating.
The height of the anti-rotation pin 2 is smaller than the thickness of a single lug of the double-lug support 7, and the assembly is convenient. The parameters of the anti-rotation pin 2 are determined by the nut tightening torque to prevent the anti-rotation pin from being screwed off; the anti-rotation pin 2 is in clearance fit with an anti-rotation pin hole on the double-lug support 7; the bolt head 1 is of a hexagonal structure.
As shown in fig. 1 and 3, the bolt head of the bolt 1 is provided with an anti-rotation pin 2, the double-lug support 7 is provided with an anti-rotation pin hole, the bolt 1 is inserted into the double-lug support 7 hole and passes through the movement mechanism 8, the anti-rotation pin 2 on the bolt head of the bolt 1 is inserted into the anti-rotation pin hole of the double-lug support 7, after the nut 9 is tightened according to the tightening torque, the split pin 6 passes through the nut notch and the split pin hole of the bolt 1, and then the split pin is prevented from loosening.
