Based on the functional description of each mechanism, the specific structure of each mechanism is described below.

The mechanism for clamping the turntable 11 as shown in fig. 2 to 3 comprises, in addition to the turntable 11 and the lock body clamp 12 as referred to above, a driving assembly for driving the turntable 11 to rotate, and a positioning assembly for positioning the turntable 11. The lock body feeding station a, the lock bolt distance detection station b, the lock bolt spring assembling station c, the lock bolt assembling station d, the lock cylinder assembling station e and the lock body discharging station f are regularly arranged along the center of the rotary table 11, namely, the included angle between the centers of two adjacent stations and the center of the rotary table 11 is 60 degrees, and the edge of the rotary table 11 is regularly provided with six groups of lock body clamps 12 with equal included angles, namely, the included angle between the centers of two adjacent groups of lock body clamps 12 is 60 degrees. The lock body clamp 12 is used for clamping and fixing a lock body, one embodiment of the lock body clamp 12 is shown in fig. 3, and the lock body clamp 12 includes a fixed seat 121 and a sliding rod 122 provided on the turntable 11, a movable seat 123 slidably provided on the sliding rod 122, and a return spring 124 and an adjusting assembly for driving the movable seat 123 to move. The rod body direction of the sliding rod 122 faces the fixed seat 121, a clamp opening is formed between the movable seat 123 and the fixed seat 121, one side of the clamp opening is an entrance end of the clamp opening, and the other side of the clamp opening is provided with a limiting component 126, such as a limiting screw.

The adjusting assembly includes a fixed plate 127 fixed on the outer rod of the movable base 123, a movable plate 128 connected below the fixed plate 127, and an interference plate 129 fixed on the movable plate 128. A compression spring 120 is arranged between the fixed plate 127 and the movable plate 128, a plate body of the interference plate 129 is arranged between the movable seat 123 and the fixed plate 127, and the upper end part of the interference plate 129 is in inclined plane fit with the movable seat 123. The fixed seat 121 is provided with a first clamping block, and the movable seat 123 is provided with a second clamping block. Arc clamping openings are formed in the first clamping block and the second clamping block, and the arc clamping openings of the first clamping block and the second clamping block are horizontally opposite. The lock body clamp 12 changes the clamping mode of the traditional clamp, and the longitudinal acting force applied by the movable plate 128 in the clamp assembly can be converted into the transverse movable force of the movable seat 123, so that the driving mode of the clamp assembly is simplified. In the rotating process of the turntable 11, the lock body clamp 12 is required to be in an open state except when passing through the lock body feeding mechanism and the lock body discharging mechanism, and is required to be in a locking state when passing through the lock bolt distance detecting mechanism, the lock bolt spring assembling mechanism, the lock bolt assembling mechanism and the lock cylinder assembling mechanism. In the above scheme, the compression spring 120 tightens the interference plate 129 downwards only under the action of the compression spring 120, so as to press the movable seat 123 to be close to the fixed seat 121, and the clamp opening becomes smaller and is in a locking state. When the lock body clamp 12 is required to be opened for loading and unloading, the movable plate 128 is required to be acted by external force, so that the interference plate 129 is lifted up, the movable seat 123 is far away from the fixed seat 121 under the action of the return spring 124, and the clamp opening is enlarged and is in an opened state.

The turntable 11 rotates intermittently at equal angles, so the driving assembly preferably adopts a stepping motor and drives the turntable 11 to rotate through a belt. Further, in order to ensure that the turntable 11 does not deflect when the stations are assembled, the turntable 11 needs to be positioned by a positioning assembly to maintain the turntable 11 in a positioned state. In this embodiment, the turntable 11 between two adjacent lock body clamps 12 is provided with a positioning notch 15, and the adjacent positioning notch 15 is also regularly arranged on the turntable 11 by adopting a 60-degree included angle. The positioning assembly comprises a positioning cylinder 16 fixed on the frame 1 and a positioning block 17 arranged on the output end of the positioning cylinder 16. When the turntable 11 rotates for 60 degrees, the positioning cylinder 16 sends the positioning block 17 into the corresponding positioning notch 15 to position the turntable 11, each mechanism works respectively during positioning, after the positioning is finished, the positioning cylinder 16 sends the positioning block 17 out of the positioning notch 15, and the turntable 11 continues to rotate for 60 degrees under the action of the stepping motor and then performs positioning.

The lock body feeding mechanism shown in fig. 2 and 4 comprises a feeding bracket 21, and a feeding sliding rail 22 and a feeding assembly which are arranged on the feeding bracket 21. When the turntable 11 on the clamping turntable 11 mechanism rotates to a proper position, the tail end of the feeding slide rail 22 corresponds to the inlet end of the clamp opening, after the lock body enters the feeding slide rail 22, the lock body is pushed into the clamp opening by the feeding assembly, and as the limiting part is arranged in the clamp opening, the position of the lock body in the clamp opening is specific, namely one side of the lock body abuts against the limiting part.

In addition, since the lock bolt hole 93 on the lock body may generate burrs on the hole wall after the hole is opened, which may affect the operation of the lock bolt and the lock bolt spring, the lock bolt hole 93 needs to be deburred before the lock bolt and the lock bolt spring are assembled. In this embodiment, the lock body feeding station a is further provided with a lock bolt hole burr treatment device, the lock bolt hole burr treatment device comprises a jack cylinder 26 and a jack rod 27 arranged at the output end of the jack cylinder 26, the jack cylinder 26 is arranged right above the lock body clamp 12 corresponding to the lock body feeding station a and can be fixed on the support column 14, the output end of the jack cylinder 26 faces downwards vertically, and the jack rod 27 corresponds to the lock bolt hole 93 on the lock body. The jack cylinder 26 drives the jack rod 27 into the lock tongue hole 93, and the jack rod 27 removes burrs on the wall of the lock tongue hole 93. The jack rod 27 is a hollow rod body and is connected with an air source pipe, and after the jack procedure is finished, air is introduced into the jack rod 27 to blow, so that the burrs under polishing are blown off.

In the punching process of the lock body, the distance between the lock Liang Jiankong and the lock core hole has errors due to the process and the quality of the lock body, so that the length of the lock tongue is correspondingly changed in order to ensure the quality of the lock in the installation process. Therefore, it is important to measure the distance from the lower hole wall of lock Liang Jiankong 91 to the upper hole wall of lock cylinder hole 94, and the distance from the lock tongue to the detection mechanism in the device is the distance from the lower hole wall of lock Liang Jiankong 91 to the upper hole wall of lock cylinder hole 94, so as to determine the required length of the lock tongue installed in the lock body.
