This requires that automated production lines or manual assembly lines must take into account the requirements of flexibility while ensuring high efficiency. For workstations that use vacuum adsorption to tighten, the same problems will also be faced. Currently, the common vacuum tightening ends on production lines are completely fixed, and cumbersome operations are required for replacement: such as first disassembling the nail suction device, and then disassembling the suction head. After disassembly, it is necessary to install them back in turn. Such operations are not only cumbersome but also time-consuming. At the same time, in many cases, further debugging may be required after replacement, which requires relatively high technical capabilities of operators and reduces production efficiency.

[0026] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0027] As shown Figures 1 - 6 in the figure, a vacuum adsorption tightening end includes a mounting base 2 and a vacuum adsorption end 3. The mounting base 2 is mounted on a rotary tool 1, and the execution end of the rotary tool 1 is detachably mounted with a tightening tool 4. One end of the mounting base 2 is detachably mounted with the vacuum adsorption end 3 through an elastic member 5. The periphery of the tightening tool 4 is located inside the vacuum adsorption end 3. The vacuum adsorption end 3 is used to suck and connect a part 6. One end of the tightening tool 4 can be clamped to one end of the part 6, and the rotary tool 1 can drive the part 6 to rotate through the tightening tool 4. The rotary tool 1 is an electric rotary machine of the prior art and can be suspended at the work station. The tightening tool 4 is a screwdriver of the prior art. One end of the tightening tool 4 is detachably mounted on the rotating end of the rotary tool 1. By adding a mounting base 2 to the rotary tool 1, the vacuum adsorption end 3 can be quickly disassembled and assembled through the elastic member 5 on the mounting base 2. Moreover, the mounting base 2, the rotary tool 1, the tightening tool 4, and the vacuum adsorption end 3 are coaxially arranged, reducing the debugging time of the staff, being convenient and fast for disassembly and assembly, reducing the operation difficulty of this process, and improving the production efficiency.

[0028] In implementation, the elastic member 5 is any one of a circlip or a circular tension spring. As shown Figure 5 in the figure, the elastic member 5 in this embodiment is a circular tension spring.

[0029] To ensure that the elasticity can fix the relative position with the mounting base 2 and the mounting base 2 does not interfere with the elastic member 5 to fix the vacuum adsorption end 3, a plurality of bosses 21 are circumferentially arranged at one end of the mounting base 2, and the periphery of the vacuum adsorption end 3 is located on one side of each boss 21. A groove 22 is arranged on the other side of the boss 21, and the periphery of the elastic member 5 is located in the groove 22. A ring groove 36 is arranged on the periphery of one end of the vacuum adsorption end 3, and the periphery of the elastic member 5 is located in the ring groove 36.

[0030] As shown Figure 3 and Figure 4 in the figure, the vacuum adsorption end 3 includes a housing 31. The upper end of the housing 31 is detachably connected to one end of the mounting base 2 through an elastic member 5. A vacuum suction base 32 is arranged at the lower end of the housing 31. A suction connection groove is arranged at one end of the vacuum suction base 32. The upper end of the part 6 can be sucked and connected into the suction connection groove, and the inner circle contour of the suction connection groove matches the outer periphery contour of the upper end of the part 6. To adapt to different specifications of the part 6, the matching is completed by replacing the vacuum suction base 32, reducing the structure of the replacement parts and the input cost. Moreover, in this embodiment, the part 6 is sucked and connected by the vacuum adsorption method. A cavity is arranged inside the housing 31, and a nozzle 33 is installed on the housing 31. An external vacuum pumping device is connected to the cavity through the nozzle 33, and the cavity penetrates to the vacuum suction base 32 to suck and connect the part 6.

[0031] A first annular clamping platform 34 is provided on the inner circle at the lower end of the outer shell 31, and a second annular clamping platform 35 is provided on the outer periphery at the upper end of the vacuum suction base 32. The inner diameter of the first annular clamping platform 34 is smaller than the outer diameter of the second annular clamping platform 35. The upper end of the first annular clamping platform 34 can abut against the lower end of the second annular clamping platform 35. The outer periphery of the vacuum suction base 32 can slide within the first annular clamping platform 34, and the outer periphery of the vacuum suction base 32 is hermetically connected to the inner circle of the first annular clamping platform 34. The second annular clamping platform 35 can slide relative to the first annular clamping platform 34, and the lower end of the second annular clamping platform 35 being placed on the upper end of the first annular clamping platform 34 is the lower limit of the movement of the vacuum suction base 32, preventing the vacuum suction base 32 from detaching from the outer shell 31.

[0032] A compression spring 37 is provided on the second annular clamping platform 35. An end cover 38 is installed on the inner circle at the upper end of the outer shell 31. A through hole is provided in the middle of the end cover 38. The outer periphery of the tightening tool 4 is located within the through hole, and one end of the compression spring 37 can abut against the end cover 38. The compression spring 37 is used for the elastic reset of the second annular clamping platform 35 and provides a downward pressing force for the second annular clamping platform 35.

[0033] When the device adsorbs the part 6, the upper end of the part 6 blocks into the vacuum suction base 32. When the staff transfers the part 6 to the position to be tightened through the rotating tool 1 and the vacuum adsorption end 3, the staff presses the rotating tool 1. At this time, the lower end of the vacuum adsorption end 3 is interfered by the position to be tightened and cannot move. The second annular clamping platform 35 moves away from the first annular clamping platform 34, and the compression spring 37 is compressed. The end of the tightening tool 4 is clamped to the upper end of the part 6. By driving the tightening tool 4 and the part 6 to rotate through the rotating tool 1, the part 6 is gradually screwed into the position to be tightened. During this process, the compression spring 37 always provides a downward pressing force for the vacuum suction base 32, and the lower end of the second annular clamping platform 35 gradually abuts against the lower end of the first annular clamping platform 34.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
