Service HotlineGenerally speaking, combination screws are widely used in electrical, electric, mechanical, electronic, household appliances, furniture, ships and so on. But the above said that different combination screws have different functions. For example, Phillips pan head combination screws are generally used in small electronic products. Larger cross hexagon combination screws are used in larger electrical products, such as frequency converters, and some larger frequency converters use many cross hexagon combination screws. Hit the inverter case. To loosen the tightening effect. For example, two combination screws with flower teeth, which are used on the inverter, are used to break the paint, so that all the two combination screws on the surface of the casing are powered on. There is also a two-combination screw with a square pressure line, which itself is a two-combination screw with a pan head screw and a square pad. It is generally used on the surface of the terminal block. The function is for wiring and for crimping.
Such flat gaskets typically include passage openings for fluids through which fluid can flow from one side of the flat gasket to the other side of the flat gasket. In addition, functional elements may be inserted into such passage openings, eg valve elements blocking passage in one direction, or orifice elements defining passage in one or both directions.
Combination bolts refer to a bolt with a spring washer and a flat washer, which are combined by rubbing teeth. Before the combination bolt is used, the bolt, the spring washer and the flat washer are generally combined by a specific machine. The combined production line mainly includes the processes of feeding, discharging, feeding, charging, screwing and tightening. The existing combined bolt production equipment mainly transmits the bolts to each process through the conveyor belt, and finally completes the combined assembly. The machines in each process are scattered and the space is occupied. The vibrating plate feeding generally puts the bolt head up, and its bolts, spring washers, etc. After the flat pad is assembled, the fixation is poor, and it is easy to fall off during the assembly process.
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.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35 , and the screws enter the screw accommodating hole 41 from the discharge port through the guide rail 6 . The slotting is carried out, which improves the efficiency and saves the labor cost.
