Description
Technical Field
The utility model relates to a spring pre-pressing locking device which is used for assembling a rear spring of a new energy automobile and belongs to the technical field of machinery.
Background
In the new energy automobile spring assembly process, a counterweight is needed to be added at a corresponding position of an automobile body before the spring assembly process, if the assembly is carried out without the counterweight, the spring cannot be compressed only by the dead weight of the automobile body, and the assembly cannot be carried out without the compression of the spring, and the process is time-consuming, labor-consuming and high in counterweight cost; the utility model designs a spring pre-pressing locking device which can be easily realized in the whole process by only pre-pressing the spring by using the device before assembling the spring and loosening the device after assembling the spring, thereby saving the working hours, saving the cost and improving the assembling efficiency.
Disclosure of Invention
The utility model designs a spring pre-pressing locking device.
The utility model adopts the following technical scheme.
A spring pre-pressing locking device comprises a first hexagonal nut (1), a second hexagonal nut (2), a fixed arm (3), a first hexagonal flange bolt (4), a second hexagonal flange bolt (5), a third hexagonal nut (6) and a movable arm (7); the small assembly I is characterized in that the small assembly I is formed by welding a first hexagonal nut (1), a second hexagonal nut (2) and a fixed arm (3) into a whole; the small assembly II is formed by a hexagonal flange bolt II (5), a hexagonal nut III (6) and a movable arm (7) into a whole; the small assembly I and the small assembly II are connected into a whole by a hexagonal flange bolt I (4); before the assembly of the rear spring, the lower part of the spring is hooked by the L end of the fixed arm of the first small assembly, the upper part of the spring is hooked by the L-shaped movable arm of the second small assembly, and then the spring is connected by the first hexagonal flange bolt (4), so that the spring is in a compressed state, and after the assembly of the rear spring is completed, the assembly of the rear spring can be completed by loosening the first hexagonal flange bolt (4).
