Description

Technical Field

[0001] The utility model relates to the technical field of screw locking devices, in particular to an EBS valve body side cover screw locking device. Background Art

[0002] The electric screwdriver, also known as an electric screwdriver or electric screwdriver, is a screw locking device with a wide range of uses. For example, it can be used in the assembly process of the current EBS valve body side cover. As one of the mechanical operating devices, it is mainly used to tighten and loosen screws and nuts. It is equipped with a mechanism for adjusting and limiting torque. It is mainly used in assembly lines and is relatively simple to use. It usually has two gears, forward and reverse. The forward gear is used to tighten screws, and the reverse gear is used to loosen screws. Some advanced electric screwdrivers are also equipped with an infinitely variable speed function, which can adjust the torque as needed, making it more flexible and convenient to use. The head of the electric screwdriver can be replaced as needed to adapt to screws of different specifications. When removing the electric screwdriver head, you usually only need to rotate the head and gently pull it out.

[0003] However, the applicant discovered during a long period of actual operation that the existing electric screwdrivers, due to the lack of auxiliary support and limiting guide structure, are prone to tilted force direction during the spiral locking process of long screws, causing confusion between the threads of the long screws and the threaded holes, which in turn leads to loose installation and a gradual increase in the rate of defective processing.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. After the electric screwdriver body initially engages and connects the long screw with the corresponding threaded hole, the utility model uses a magnetic suction component and a workpiece magnetic limiter, and then continues to use the working end of the electric screwdriver body to rotate and press down the long screw to make it completely threaded and locked into the corresponding threaded hole. In the engagement process, the limit guide constraint and concession between the guide rod and the first transition support plate can fully improve the success rate of the installation of the long screw and the corresponding threaded hole and reduce the defective processing rate.

[0015] 2. When the utility model faces a structural obstruction outside the threaded hole at the installation location, the second transition support plate can be directly lifted up until the maximum stroke of the guide rod. Then, the set limit screw is turned to make one end of the limit screw fit and connect with the corresponding inner wall of the yielding groove, thereby limiting the moved second transition support plate and guide rod, thereby making the second transition support plate and magnetic suction assembly idle and yielding state to meet the use requirements.
