The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

As shown in Figures 1 and 2, an automatic locking mechanism for a battery fixture is arranged on a table for placing the battery fixture, and includes a support base 1, a locking device 2 and a drive assembly 3; the locking device 2. Set on the support base 1 and connect to the drive assembly 3;

The locking device 2 includes a sliding structure 21 and a rotating locking structure 22; the rotating locking structure 22 is arranged on the sliding structure 21; the sliding structure 21 is connected to the support through a slider 211 at the bottom on the slide rail 11 of the base 1; the drive assembly 3 includes a cylinder 31 and a servo motor 32; the piston rod 311 of the cylinder 31 is connected to the rear end surface of the sliding structure 21 transversely, and the cylinder body 312 of the cylinder 31 passes through The positioning frame 4 is fixedly arranged on the support base 1, and the cylinder 31 drives its piston rod 311 to reciprocate to drive the sliding structure 21 to slide along the direction of the slide rail 11; the servo motor 32 is connected to the rotating The rear end face of the locking structure 22, the rotating locking structure 22 is driven by the servo motor 32 to rotate and lock the battery fixture on the placement table, and the limit torque control lock is set by the servo motor 32 tightness.

The present invention proposes an automatic locking mechanism for a battery fixture, which drives the locking device 2 through the drive assembly 3, and realizes the function of automatically fitting and locking the battery fixture after the battery is placed , wherein the sliding structure 21 is driven by the cylinder 31 to move horizontally in the direction of the battery fixture, and at the same time, according to the set torque, the rotary locking structure 22 is driven to rotate and tighten by the servo motor 32, so that The battery fixture is locked on the placement table.

The present invention combines the self-adaptive function of the cylinder with the torque setting of the servo motor, realizes the function of rotating and tightening while simultaneously horizontally feeding the automatic locking mechanism, and obtains a battery fixture capable of adjusting the degree of locking The automatic locking mechanism, that is, when the servo motor reaches the set limit torque, it can automatically identify and stop the rotation, effectively controlling the degree of locking; therefore, it is different from the existing manual wrench locking or automatic clamping Compared with other methods, the automatic locking mechanism proposed by the present invention can form a two-way clamping force, has a simple structure, higher stability, and good safety performance; the torque can be adjusted freely, with good controllability and high locking precision ; And it can be applied to battery fixtures of different sizes, with better adaptability.
