Description
Technical Field
The utility model relates to a manual quick lock nut, especially a hexagonal flange face nut that is used for being locked fast of machining's part belongs to the machining field.
Background
The locking nut is widely applied to the industries of machinery and the like, and the working principle of the locking nut is that the self-locking is carried out by adopting the friction force between the nut and the bolt. After the threaded fastener is tightened, the pretightening force between the connected parts is reduced, and the phenomenon is called that the fastener is loosened. The top structure of a common locking nut is subjected to compression deformation or insert treatment, when a bolt thread is screwed into a deformation or insert part of the bolt thread, the thread or the insert generates radial or axial deformation, elastic deformation plays an interference role on the thread, friction torque for preventing rotation loosening is generated, and the anti-loosening effect is achieved.
As is known, a lock nut plays an important role in the clamping and fixing of parts during the machining of the parts. Before parts are machined, the parts are generally fixed by screwing nuts one by using a wrench; after the completion, the nut needs to be loosened one by using a spanner to take out the parts, which is time-consuming and labor-consuming. When the machined part is large, more nuts are clamped and fixed, and when the nuts are screwed down or loosened, the part is easily collided, so that the quality problem is caused. If the machining clamp is installed on the machine tool, the assembly and disassembly of parts greatly occupy the effective working time of the machine tool, and the manufacturing cost is increased. In the technical field of fastening and connection, how to ensure that a nut has extremely strong reliability under dynamic load is a problem to be solved urgently at present.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem existing in the prior art and providing a manual quick locking hexagonal flange face nut which is simple and convenient to operate.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a manual quick locking hexagonal flange face nut, includes hexagonal flange face nut body, is provided with the handle at the surface of hexagonal flange face nut body for twist and move hexagonal flange face nut body.
Preferably, the end part of the hexagonal flange nut body is provided with a groove, the groove is arranged around the inner diameter of the groove, and an elastic anti-loosening ring is embedded into the groove.
Preferably, the recess is located inwardly of the end remote from the flange face.
The working principle is as follows: the elastic anti-loose ring is in a loose state when in a free state; when the handle is screwed down, the elastic anti-loosening ring works under the action of prestress and friction force to play a self-locking role; meanwhile, the full thread of the inner ring of the nut with the hexagonal flange surface plays a role in locking in the radial direction and the axial direction of the screw rod, so that an excellent self-locking and anti-loosening effect is achieved. In actual use, the tightening torque can be adjusted within a tolerance range.
Compared with the prior art, the utility model has the advantages of as follows:
1. after the handle structure is added, the operation is simple and convenient;
2. the elastic anti-loosening ring achieves a self-locking effect by means of friction force, the full threads of the working part can be adjusted within a standard tolerance range, and the anti-loosening device is reusable, high in strength, high in anti-vibration performance and high in cost performance.
3. The clamping device can be used for quickly clamping parts made of different materials, the manufacturing period is shortened, the damage risk is reduced, and the clamping quality is improved; the practicability is better, the popularization and the application are easy, and the development and application values in the professional field are higher.
4. The clamping device is used for clamping machining of tool parts, is convenient and simple for workers to use, improves the manufacturing efficiency, saves the cost, and can be popularized and used.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a top view of FIG. 1;
FIG. 3 is a view A-A of FIG. 1;
in the figure, 1, a hexagonal flange nut body; 1-1, a handle; 1-2 parts of nylon elastic anti-loosening ring.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings 1-3: a manual quick locking hexagonal flange nut comprises a hexagonal flange nut body 1, wherein a handle 1-1 is arranged on the outer surface of the hexagonal flange nut body, is fixedly connected to one of the surfaces of the hexagonal flange nut and is used for an operator to screw the hexagonal flange nut body; the end part of the hexagonal flange face nut body, far away from the flange face, is provided with a groove, the groove is arranged around the inner diameter of the groove, and a nylon elastic anti-loosening ring 1-2 is embedded into the groove.
As shown in figure 1, the handle 1-1 is held to rotate, so that manual quick locking is realized. Compared with the traditional hexagonal flange nut, the utility model can realize manual quick locking without a fastening tool on site, thereby avoiding the generation of part collision phenomenon when fastening by using a tool; the elastic anti-loose ring is in a loose state when in a free state; when the handle 1-1 is screwed down, the nylon elastic anti-loosening ring 1-2 works under the action of prestress and friction force to play a self-locking role; meanwhile, the full thread of the inner ring of the hexagonal flange face nut generates radial and axial deformation force and elastic deformation when the bolt thread is screwed into a working position, and generates friction torque for preventing rotation and looseness, so that an excellent self-locking and anti-loosening effect is achieved. In actual use, the tightening torque can be adjusted within a tolerance range. As shown in fig. 1, the full-flight specification M of the working portion thereof needs to be related to the parameters of the connecting screw. In actual production, we often use M8, M12, M16, M20, M24, and the like.
When the hexagonal flange face nut is made of steel, galvanizing passivation or oxidation is needed; when the material is stainless steel, the treatment is not needed.
The above embodiments are merely preferred embodiments of the present invention, and do not limit the present invention. It will be understood by those skilled in the art that any extension and modification made without departing from the principles of the present invention are within the scope of the present invention.
