Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of nuts, and in particular relates to a hexagonal flange nut with a conical flange surface. Background Art
[0002] In modern industrial manufacturing and mechanical assembly, connection and tightening are key links to ensure stable equipment operation and guarantee product quality and safety. As a commonly used connection component, hexagonal flange nuts with tapered flange surfaces play an important role in many scenarios due to their unique structural design. For example, they can be seen in the connection of key components in automobile engines, the structural tightening of large mechanical equipment, and the precision assembly of aerospace equipment. However, with the rapid development of industrial technology towards high precision and high reliability, higher requirements are placed on the performance of connection components. Hexagonal flange nuts with tapered flange surfaces have gradually exposed some problems in practical applications.
[0003] During the maintenance and overhaul of equipment, removing nuts is a frequent and important operation. However, for tapered flange hexagonal nuts, it is more difficult to remove them. Tapered flange hexagonal nuts have more flange surfaces and tapered surfaces than traditional hexagonal nuts, which makes the fastening effect better than traditional hexagonal nuts. However, because of the extra contact surface, the friction between them and the parts to be fixed will increase, so the tapered flange hexagonal nuts will be more difficult to remove than traditional hexagonal nuts.
[0004] In some complex working conditions with frequent vibration and impact, such as engineering machinery and transportation vehicles, the anti-loosening performance of conical flange hexagonal nuts is limited. Although the design of the flange surface and conical surface can increase friction and provide a certain anti-loosening effect to a certain extent, the nut may still loosen when facing continuous dynamic loads. Therefore, we propose a hexagonal flange nut with a conical flange surface. Summary of the Invention
[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a hexagonal flange nut with a tapered flange surface, which effectively solves the problem that traditional tapered flange hexagonal nuts have more flange surfaces and tapered surfaces than traditional hexagonal nuts, thereby making the fastening effect better than traditional hexagonal nuts. However, because of the extra contact surface, the friction between it and the fixed part will increase, so the tapered flange hexagonal nut will be more difficult to disassemble than the traditional hexagonal nut. In some complex working conditions with frequent vibrations and impacts, the anti-loosening performance of the tapered flange hexagonal nut is limited. However, under continuous dynamic loads, the nut may still become loose.
[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a hexagonal flange nut with a tapered flange surface, comprising a tapered flange hexagonal nut, a disassembly assembly and a locking assembly, characterized in that: the disassembly assembly is located inside the tapered flange hexagonal nut, and the locking assembly is located inside the disassembly assembly; A group of notched grooves are provided on both sides of the conical flange hexagonal nut, and a threaded hole is provided through the inner side of the notched groove. The disassembly and assembly component includes a filling block, and the filling block is arranged in the notched groove. A group of internal threaded countersunk holes are provided on the opposite sides of the two groups of filling blocks. Cross bolts are screwed into the internal threaded countersunk holes and the threaded holes. The cross bolts pass through the threaded holes and are connected to anti-slip pads.
[0007] Preferably, a group of guide grooves are provided on both the front and rear sides of the filling block, and a group of guide blocks are provided on both the front and rear sides of the inner side wall of the notch groove, and the guide blocks are arranged in the guide grooves.
[0008] Preferably, the locking assembly includes a handle, a guide column is provided on the top of the handle, a high-strength spring is provided on the top of the guide column, a positioning pin is provided on the bottom of the handle, and a magnet is embedded in the bottom of the positioning pin.
[0009] Preferably, the outer side of the filling block is flush with the outer side of the conical flange hexagonal nut, and an easy-to-pull groove is provided on the top of the inner side wall of the handle.
[0010] Preferably, a locking hole is provided on the top of the screw head of the cross bolt, and a group of sliding grooves are provided on opposite sides of the two groups of filling blocks.
[0011] Preferably, a through hole is provided between the slide groove and the internal thread countersunk hole, and a mounting hole is provided on the top of the inner side wall of the slide groove.
[0012] Preferably, the handle and the guide column are both arranged in the slide groove, the high-strength spring is arranged in the mounting hole, and the top of the guide column is arranged in the mounting hole.
[0013] Preferably, the bottom of the positioning pin passes through the through hole and is inserted into the locking hole, and the magnetic block is magnetically attracted in the locking hole.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The filling block can be fixed in the notch groove of the tapered flange hexagonal nut by the cross bolt, so that the tapered flange hexagonal nut and the two sets of filling blocks are combined into a complete tapered flange hexagonal nut. When the cross bolt is tightened, the anti-slip pad can be driven to move inward to fit tightly with the external bolts screwed to the tapered flange hexagonal nut, thereby improving the vibration resistance and loosening resistance of the tapered flange hexagonal nut. 2. The cross bolt can be firmly locked by the locking assembly to ensure the stability of the combination of the tapered flange hexagonal nut and the two sets of filling blocks, as well as the reliability of the anti-vibration and anti-loosening performance of the tapered flange hexagonal nut, thereby improving the reliability of the device; 3. After unlocking the cross bolt by moving the handle upward, and rotating the cross bolt to separate the cross bolt and the anti-slip pad from the tapered flange hexagonal nut, the handle can be pulled diagonally upward to drive the filling block to be pulled out from the notch of the tapered flange hexagonal nut, thereby ensuring the convenience of using the device. By removing the filling block, the contact area between the tapered flange hexagonal nut and the part to be fixed can be greatly reduced, thereby reducing the resistance to disassembly of the tapered flange hexagonal nut, thereby reducing the difficulty of disassembly of the tapered flange hexagonal nut.

[0019] like Figure 1-4As shown, the present invention provides a technical solution: a hexagonal flange nut with a tapered flange surface, comprising a tapered flange hexagonal nut 1, a disassembly assembly 200 and a locking assembly 300, wherein the disassembly assembly 200 is located in the tapered flange hexagonal nut 1, and the locking assembly 300 is located in the disassembly assembly 200; A group of notched grooves are provided on the left and right sides of the tapered flange hexagonal nut 1, and a threaded hole is provided through the inner side of the notched groove. The disassembly and assembly component 200 includes a filling block 11, and the filling block 11 is slidably set in the notched groove. A group of internal threaded countersunk holes are provided on the opposite sides of the two groups of filling blocks 11, and a cross bolt 13 is screwed in the internal threaded countersunk holes and the threaded holes. The cross bolt 13 passes through the threaded hole and is connected with an anti-slip pad 15. When the tapered flange hexagonal nut 1 is tightened with the external bolt, the cross bolt 13 can be tightened to drive the anti-slip pad 15 to move inward and fit tightly with the external bolt screwed with the tapered flange hexagonal nut 1, so as to improve the vibration and anti-loosening properties of the tapered flange hexagonal nut 1. A group of guide grooves are provided on the front and back sides of the filling block 11, and a group of guide blocks 12 are fixedly provided on the front and back sides of the inner wall of the notched groove. The guide block 12 is slidably set in the guide groove to lock The component 300 includes a handle 14, a guide column 16 is fixedly provided on the top of the handle 14, a high-strength spring 17 is fixedly provided on the top of the guide column 16, a positioning pin 18 is fixedly provided on the bottom of the handle 14, and a magnet 19 is embedded in the bottom of the positioning pin 18. The outer side of the filling block 11 is flush with the outer side of the conical flange hexagonal nut 1, and an easy-to-pull groove is provided on the top of the inner wall of the handle 14. A locking hole is provided on the top of the screw head of the cross bolt 13. A group of slide grooves are provided on the opposite sides of the two groups of filling blocks 11, and a through hole is provided between the slide grooves and the internal threaded countersunk holes. A mounting hole is provided on the top of the inner wall of the slide groove. The handle 14 and the guide column 16 are both slidably set in the slide groove, the high-strength spring 17 is fixedly set in the mounting hole, the top of the guide column 16 is slidably set in the mounting hole, the bottom of the positioning pin 18 passes through the through hole and is inserted into the locking hole, and the magnet 19 is magnetically attracted to the locking hole.
[0020] A method of using a hexagonal flange nut with a tapered flange surface: Step 1: Move the handle 14 upward to drive the locating pin 18 to separate from the locking hole of the cross bolt 13, and then use a cross screwdriver to rotate the cross bolt 13 so that it moves spirally outward along the threaded hole of the tapered flange hexagonal nut 1, thereby driving the anti-slip pad 15 to move into the threaded hole. At this time, the tapered flange hexagonal nut 1 can be screwed to the external bolt to fix the part to be fixed.
[0021] Step 2: After the conical flange hexagonal nut 1 is tightened with the external bolt, the cross bolt 13 can be tightened to drive the anti-skid pad 15 to move inward and fit tightly with the external bolt screwed with the conical flange hexagonal nut 1, thereby improving the vibration and anti-loosening properties of the conical flange hexagonal nut 1. At the same time, the cross bolt 13 will also fix the filling block 11 in the notch groove of the conical flange hexagonal nut 1, so that the conical flange hexagonal nut 1 and the two sets of filling blocks 11 are combined into a complete conical flange hexagonal nut. When the cross bolt 13 is tightened, the locking hole on the cross bolt 13 It will be aligned with the locating pin 18. At this time, the handle 14 is released, and the resilience of the high-strength spring 17 is used to drive the handle 14 to move downward and reset through the guide column 16. The locating pin 18 is driven downward by the handle 14 and inserted into the locking hole of the cross bolt 13. At the same time, the magnetic block 19 will be magnetically attracted to the locking hole to improve the insertion stability of the locating pin 18. The mutual cooperation between the high-strength spring 17 and the magnetic block 19 can effectively ensure the locking reliability of the locating pin 18 to the cross bolt 13, thereby ensuring the reliability of the anti-vibration and anti-loosening performance of the tapered flange hexagonal nut 1.
[0022] Step 3: When the conical flange hexagonal nut 1 needs to be removed, the handle 14 is moved upward to drive the locating pin 18 to separate from the cross bolt 13, and then the cross bolt 13 is rotated to drive the anti-slip pad 15 to move inward into the internal thread countersunk hole of the filling block 11. At this time, the handle 14 can be pulled upward obliquely to drive the filling block 11 along the guide block 12 to be pulled out of the notch groove of the conical flange hexagonal nut 1, thereby greatly reducing the contact area between the conical flange hexagonal nut 1 and the part to be fixed, thereby reducing the resistance to disassembly of the conical flange hexagonal nut 1, and thus reducing the difficulty of disassembly of the conical flange hexagonal nut 1.
