Service HotlineSwimming self-locking nut GJB 125.1～125.6-86 The double-ear sealing swimming self-locking nut is composed of four parts: sealing cover, self-locking nut, pressure ring and sealing ring. It has compact structure and reliable sealing, and is suitable for products whose working pressure is not more than 2atm, working medium is gasoline, kerosene, water or air, and the operating temperature is -50～100℃. However, it has certain difficulties in the manufacturing process and air tightness test.
An automatic screw-removing device for automatically removing screws on a workpiece, the automatic screw-removing device comprising a worktable, a manipulator disposed on one side of the worktable, and a screw-removing mechanism installed on the manipulator, The screw-removing mechanism includes an installation plate connected to the manipulator, an electric batch installed on the installation plate, a bit head disposed on one side of the electric batch, and a visual recognition unit disposed on the installation plate , the visual recognition unit takes pictures of the screw to determine the coordinates of the screw, the bit is rotated under the drive of the electric batch to disassemble the screw, the bit is magnetic and can be adsorbed the screw.
In another embodiment of Guangdong Yueluo Hardware Industrial Co., Ltd., the conveying device 3 includes a motor 31 and a circular rotating disk 34, the motor 31 drives the circular rotating disk 34 to rotate, and the circular rotating disk 34 is evenly provided with screws in the circumferential direction. The matching screw accommodating hole 35, the screw enters the screw accommodating hole 35, the motor 31 drives the circular rotating plate 34 to rotate, so that the screw is first slotted by the cutting wheel 42, and then polished by the fixing wheel 48, and the screw is in the screw accommodating hole 35. It is fixed, which is more secure and reliable during the slotting process. Preferably, the circular rotating disk 34 includes a circular rotating disk 32 and a sector-shaped fixed disk 33. The circular rotating disk 32 is evenly provided with screw receiving recesses matching the screws in the circumferential direction, and the recesses and the sector-shaped fixed disk 33 are formed with the screws The matching screw receiving holes face the cutting wheel 42 and the fixing wheel 54 .
However, although the above-mentioned screw belt (2) can achieve the expected effect, it is also found in its actual implementation. Although this structure has multiple grooves on both sides of the main body for the driving and turning of the locking screw tool, However, the groove is only used for driving the screw belt drive, and since the screw will swing on the screw belt, it is impossible to stably align the screw on the screw belt with the point where the screw is to be set. , which leads to great inconvenience in operation and use, and also affects the efficiency of screw and screw installation, so that there is still room for improvement in the overall structural composition.
At the beginning of the quality inspection process broadcast, we ordered the cross recessed screw and screw wire material into our production screw industry. For manufacturers in the screw industry, we must first detect the wire diameter of the screw wire and the material of the screw. Generally, the wire diameter of the screw is measured by a caliper and a measuring wire. Diameter size, whether it is the same as the size ordered by yourself. After testing these, it is the testing in the production process, starting from the head of the screw, to determine the size of the head, the opposite side of the head, the diagonal angle, the depth of the cross groove, the tolerance range of the screw, and so on. These are checked with calipers. In the inspection of all aspects when rolling teeth, the main thing is whether the thread can pass the pass and stop gauge, and whether the screw thread can pass the gauge and stop. Next is the electroplating measurement problem. After electroplating, whether it meets the requirements of environmental protection and whether it can pass the time required by the salt spray. Tools include environmental testing machines and salt spray testing machines. In short, in the production and sales process of cross recessed screws, there must be necessary tools to detect the quality of screws. The summary should be summarized as follows: calipers, hardness testers, salt spray machines, environmental testing machines, pass and stop gauges, etc. .
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: cylindrical elongated top post, gong mother nylon butterfly ingot hand-tightened claw horn butterfly nut, hollow chassis motherboard computer screw column, copper screws and other products, we can Provide you with the right fastener solution for you.
