[0034] The bolt tightening mechanism 4 consists of at least two sets of bolt tightening assemblies. The bolt tightening assembly includes a guide rail mounting plate, an X-axis translation electric cylinder, a Y-axis sliding cylinder, an X-axis guide rail, a Y-axis guide rail, and a torque gun. The bottom of the bracket 5 is connected to the mounting plate 2.

[0039] 1. First, place the caliper housing in the middle of the stop 3-9 on the product tray 3-8, and position it using the positioning pin 3-10 on the product tray 3-8. The positioning pin 3-10 and the stop 3-9 are used to prevent the caliper housing from being misplaced. If misplaced, the caliper housing cannot be placed on the product tray 3-8.

[0040] 2. Press the control button on the control panel 6. The pressure block 3-6 moves downward through the clamping cylinder 3-4 and presses against the caliper housing. The product tray 3-8 is raised through the lifting cylinder 3-1. The floating joint 3-7 reduces the eccentricity of the lifting cylinder 3-1 and ensures a smooth lifting process.

[0041] 3. The torque gun 4-8 automatically positions itself to the guide pin bolt along the Y-guide rail 4-5 via the Y-axis sliding cylinder 4-6. The torque gun 4-8 then tightens the guide pin bolt forward via the X-axis translation electric cylinder 4-3. The torque gun 4-8 reads the value. If the value exceeds or falls below the standard value, the software will issue a red alarm, thus detecting whether the tightening is in place.

[0042] 4. After the guide pin bolts are tightened, the torque gun 4-8 exits the caliper housing, the product tray 3-8 descends via the lifting cylinder 3-1, the pressure block 3-6 releases the caliper housing, and after the caliper housing is removed, it can be used for the assembly of the next workpiece.
