Service HotlineMine trucks are required for underground construction and coal transportation. With the vigorous development of energy, the output of coal has increased significantly, and the demand for mine trucks has increased. The axle card is an important part of the mine car. Its shape is irregular, and the blank is a casting. It needs to be finished on the semicircular surface whose upper center is matched with the mine car axle. At present, the mine truck axle card is generally processed by a milling machine, which has the problem of low efficiency.
It is used for fastening in the machinery, construction and electrical industries. One end is a hexagonal head for wrench tightening, and the other end is a thread. According to different thread lengths, it is divided into full thread and half thread, abbreviated as: GB bolt.
In the prior art, the screw suction device can be implemented in the following two ways. One is to use a magnet to magnetize the electric bit head, and the electric bit head is used to approach the screw, and the screw is stuck by the electric bit head, so that the function of picking up the screw can be realized; The vacuum generator is used to form a negative pressure in the screw guide groove, and the screw is sucked into the tube to realize the screw pickup. The disadvantage of this solution is that in the process of picking up the screws, the grooves of the screws cannot be aligned, which leads to the deviation or leakage of the screws. The disadvantage of this solution is that the screw with an aspect ratio of less than 1.8 is prone to suction and skew, and the stability is not high. It can be seen that the existing technology still needs to be improved and developed.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide an improved lock nut to solve the problem that the production technology of the prior art products is too complicated. For realizing the above-mentioned purpose, Guangdong Yueluo Hardware Industry Co., Ltd. adopts following technical scheme—a kind of locking nut, which comprises that the bottom of the nut is a circle, the middle part is a hexagon, and the top is a circle, and there are bolts in the center.
At present, injection molding screws are widely used in various electronic and automotive components, including a body, the middle of which is provided with a through hole 3, the body head 1 has a hexagonal cross-section, and the tail 2 is provided with screw teeth. When in use, the middle through hole 3 of the main body will first put the wire harness, and then fix it by injection molding from the head I, and the threads of the tail 13 should be connected and installed with other components. Because the head I of the main body is hexagonal, the torque provided after injection molding is insufficient. Therefore, after the external thread is installed and connected with other components, the head is prone to slip, the installation is not reliable, and there is no push-pull force, resulting in product failure and increased safety hazards.
