[0034] Preferably, in the embodiment, positioning shaft sleeve 5 and sleeve assembly 3 are both transversely arranged, and by holding and taking screw 13, screw 13 without magnetism can be held and taken, so that the suction locking mechanism can be installed laterally.

[0035] Preferably, the sleeve assembly 3 is provided with a telescopic part, the telescopic control assembly 4 is connected with the telescopic part, and is used for controlling the telescoping of the telescopic part relative to the positioning sleeve 5. The telescopic control assembly 4 is provided with an elastic unit, and when the telescopic control assembly 4 controls the telescopic part to contract, the elastic unit can be synchronously extruded and contracted to generate potential energy. Therefore, when the screw 13 is assembled, the driving source for contracting the elastic unit stops outputting, so that the elastic unit can provide torque to the telescopic part to press the screw 13 tightly on the workpiece. Preferably, the telescopic part includes a connecting rod 8, a sleeve head 6 and a connecting sleeve 7; the telescopic control assembly 4 includes a connecting seat 14, a connecting piece 15, a sliding driving unit and an elastic unit. The connecting seat 14 is provided in a T shape and is connected with the connecting rod 8 in the telescopic part at the lower part. The connecting piece 15 is fixedly connected and arranged between the connecting seat 14 and the elastic unit. The elastic unit is fixedly arranged on the rack 1. The sliding driving unit is arranged between the rack 1 and the connecting seat 14. The elastic unit is a spring 16 in this embodiment, and there are two springs 16. The rack 1 is provided with a through slot 28. One end of the spring 16 is fixedly connected with the inner wall of the through slot 28. The other end is abutted with the connecting piece 15. Further, in this embodiment, the sliding driving unit is a combination of a sliding block 17 and an electric sliding table 18. The sliding block 17 is fixedly installed at the bottom of the rack 1. The electric sliding table 18 is fixedly installed on the connecting seat 14. The two are relatively moved by driving, so that the connecting seat 14 moves transversely relative to the rack 1, and the spring 16 is extruded by the connecting piece 15 to generate potential energy and provide torque. When the screw 13 is in contact with the mounting hole of the workpiece, the electric sliding table 18 closes the torque of the sliding block 17, so that the sliding driving unit is used as a moving pair. At this time, the elastic unit provides torque to tightly abut the screw 13 with the mounting hole at the port, so as to avoid the problem of reduced connection accuracy caused by looseness. Then, in the process of continuing to approach the workpiece, the spring 16 continues to contract, and the screw 13 can be tightly installed in the mounting hole. In other embodiments, the sliding driving unit can also be other moving pairs matched as a drive, such as a sliding rail sliding block 17 matched with a pneumatic cylinder, which will not be described here.

[0036] Further, the inside of the spring 16 is coaxially provided with a pin column 19. One end of the pin column 19 is fixedly arranged on the inner wall of the through slot 28. By arranging the pin column 19, the spring 16 can be provided with a certain guiding effect, so as to be more stable.

[0037] Preferably, the telescopic part is provided with a positioning part 20 and a movable part 21, the positioning part 20 is configured to be adapted to slide with the positioning shaft sleeve 5, so that when the positioning part 20 passes through the positioning shaft sleeve 5, the telescopic part is coaxial with the positioning shaft sleeve 5; in this embodiment, the positioning part 20 is provided as a section of the connecting rod 8 with the same diameter as the inner diameter of the positioning shaft sleeve 5, so that when the positioning part 20 is located in the positioning shaft sleeve 5, the sleeve assembly 3 can be self-positioned and stable, and can be aligned when the screw 13 is sucked, and can also improve the accuracy of docking the workpiece mounting hole, so as to dock the screw 13.

[0038] Further, the movable part 21 is configured to be able to deflect relative to the positioning shaft sleeve 5 when the movable part 21 passes through the positioning shaft sleeve 5. In this embodiment, the movable part 21 is configured as a section of the connecting rod 8 with a smaller diameter than the inner diameter of the shaft sleeve, so that the connecting rod 8 can move relative to the positioning shaft sleeve 5. In other embodiments, a spherical joint with the same diameter can also be used as a connecting point, which will not be described in detail here.

[0039] Further, the telescopic part is connected to the telescopic control assembly 4 through a spherical joint bearing 22. That is, the end of the connecting rod 8 away from the sleeve head 6 is fixedly connected through the spherical joint bearing 22, which serves as a fulcrum. Further, the sleeve assembly 3 is also provided with a universal joint 23, one end of the universal joint 23 is connected to the tail end of the connecting rod 8, and the other end is connected to the tightening gun 2, so that the tail end of the connecting rod 8 serves as a control point. When the tightening gun 2 drives the connecting rod 8 through the universal joint 23, the connecting rod 8 can have a certain degree of activity, realizing a one-angle deflection. Further, after the screw 13 is aligned with the mounting hole, the torque of the pressing screw 13 is increased during the process of pressing the screw 13 against the workpiece to compress the elastic unit, the movable part 21 is located in the positioning shaft sleeve 5, the sleeve assembly 3 is in an active state, and the tightening gun 2 applies a torque to further lock the screw 13. The perpendicularity requirement of the suction and locking mechanism to the workpiece can be reduced, and the sleeve assembly 3 can better assemble the screw 13 to the workpiece. The universal joint 23 can reduce the coaxiality requirement of the sleeve assembly 3 and the tightening gun 2, and its specific structure is prior art, which will not be described in detail here.

[0040] Specifically, when the telescopic control assembly 4 controls the telescopic part to contract, the spring 16 is extruded to store potential energy, the positioning part 20 on the connecting rod 8 is located at the position through the positioning shaft sleeve 5, the screw 13 is initially docked on the mounting point of the workpiece, the sliding drive unit stops driving to provide force, so that the potential energy of the spring 16 itself provides a lateral moment of the sleeve assembly 3, so that it stably presses the screw 13 on the port of the mounting hole, then continues to make the mechanism body close to the workpiece, the pressing moment continues to increase, and the movable part 21 is located at the positioning shaft sleeve 5, since the connecting rod 8 is not limited by the positioning shaft sleeve 5, it can be deflected by a certain angle, so that the sleeve assembly 3 can better dock the workpiece, so that the screw 13 can be precisely tightened through the tightening gun 2.

[0041] Further, in the embodiment, in order to facilitate the smooth conversion of the positioning part 20 and the movable part, a first inclined part 24 with gradually changing diameter is arranged at the connecting rod 8 between the positioning part 20 and the connecting part, and a second inclined part 25 with gradually increasing inner diameter from inside to outside is arranged at the inside end of the positioning shaft sleeve 5, that is, the end close to the positioning part 20, so that when the positioning part 20 is inserted into the positioning shaft sleeve 5, it plays a guiding role and facilitates docking.

[0042] Preferably, in order to more accurately determine the position of the connecting seat 14 relative to the rack 1, the photoelectric switch 26 is arranged on the connecting seat 14, and the sensing sheet 27 is arranged on the rack 1, so that whether the connecting seat 14 and the sleeve assembly 3 return to the initial position can be determined, so as to perform the assembly next time.

[0043] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
