Service HotlineBolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
Axle card is a kind of hole-to-hole movement installed on a slotted shaft and used as a fixed component. The inner diameter of this type of retaining ring is slightly smaller than the diameter of the assembly shaft. Application No. 201621153710.9 discloses a shaft card assembly device, including a feeding mechanism, a material distribution mechanism, a material reclaiming mechanism and an assembling mechanism. The feeding mechanism is connected with the feeding mechanism. The reclaiming mechanism includes a reclaiming tool and a servo system for driving the movement of the reclaiming tool. One end of the reclaiming tool is provided with a c-shaped opening, and an incision connected with the c-shaped opening is provided. The assembling mechanism includes a carrier for fixing the parts to be loaded and a turntable, and the carrier is mounted on the turntable. In the above shaft card assembly device, after the feeding mechanism completes the feeding, the material distribution mechanism separates the shaft card to a specific position with a fixed attitude, and then the private server drives the reclaiming tool to clamp the shaft card and assemble it to the pre-fixed by the assembly mechanism. on the fitting. During the assembly process, the manual workload is small, the efficiency is high, and the labor intensity is small. At the same time, the c-shaped opening and the cutout at the end of the reclaiming tool are designed to effectively form an elastic force to clamp the clamping shaft card and absorb the assembly process. The resulting outward deformation force avoids the plastic deformation of the shaft card due to the large external force.
Below in conjunction with the accompanying drawings, Guangdong Yueluo Hardware Industry Co., Ltd. is described in further detail. Please refer to FIG. 2 and FIG. 3, a locking nut includes a nut 1, the bottom is circular, the middle is hexagonal, the top is circular, there is a bolt hole in the center, and the side wall of the bolt hole is threaded. A number of flattening notches 2 are arranged on the top of the nut. According to the locking nut of the preferred embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the number of the flattening notches 2 is three. Due to the above features, the three flattening gaps can be used as the focal point of the tightening tool and the clamping place of the anti-loose gasket bayonet, and the structure is simple and can be formed by die stamping at one time. The above disclosure is only a preferred embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., and does not limit itself. Any person skilled in the art, without violating the spirit of the present invention, can think of changes that fall within the scope of It is within the protection scope of Guangdong Yueluo Hardware Industry Co., Ltd.
After the centrifugal fan blade is assembled in the square cabinet, it needs to be fixed with nuts. The components needed to fix the centrifugal fan blades are gaskets, washers and nuts. During the operation, it is necessary to assemble the gasket, washer and nut in sequence, then drip the fastening glue, and then fix it.
The circlip lifting and tightening mechanism includes a lifting mechanism and a tightening mechanism; the lifting mechanism includes a lifting cylinder and a ball screw; the output shaft of the lifting cylinder is connected with the ball screw; the ball screw drives the tightening mechanism to achieve up and down move; the tightening mechanism includes a tightening motor, and the output shaft of the tightening motor drives a pinion sleeved on the output shaft to rotate; the pinion drives the largest gear meshed with it to rotate, and the largest gear is driven by The second largest gear meshed with it rotates; the diameter of the first largest gear is the same as that of the second largest gear; the lower ends of the rotating shafts of the first largest gear and the second largest gear are equipped with rotating discs, and each rotating disc is fixedly installed A probe; two probes can be inserted into the two holes of the circlip at the same time, and the circlip can be tightened or loosened as the motor rotates.
