Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figure 1 As shown, the floating tightening mechanism of this embodiment includes:

[0032] The rotating drive device is installed on the support frame 2, and includes a rotating motor 11 and a rotating clamping plate 12. The rotating motor 11 is installed on one side of the support frame 2, and the rotating clamping plate 12 can be rotatably installed on the support frame 2. The rotating motor 11 drives the rotating clamping plate 12 to rotate; the rotating drive device adopts the DTN200 hollow rotating platform.

[0033] like Figures 2 to 4 As shown, the floating device includes a floating shaft 21, a floating mounting cover 20 is provided on the support frame 2, one end of the floating shaft 21 is movably installed in the floating mounting cover 20, and the floating shaft 21 can rotate and shake, that is, it can float. A first working channel 22 is provided in the floating shaft 21, and a locking buckle 221 is provided in the first working channel 22. The locking buckle 221 is movably installed in the first working channel 22 through a first spring 222, and the locking buckle 221 of the first working channel 22 is used to fix the shaft portion of the part 3.

[0034] A second working channel 23 is provided in the floating shaft 21, a sliding rod 231 is slidably provided in the second working channel 23, a second spring 232 is provided at one end of the sliding rod 231, a pin hole is provided on the sliding rod 231, a pin shaft 233 cooperating with the pin hole is provided in the second working channel 23, the front end of the sliding rod 231 cooperates with the locking buckle 221, and the locking buckle 221 is squeezed out by the entry of the sliding rod 231; the second working channel 23 is used to drive the movement of the locking buckle 221.

[0035] A third working channel 24 is provided in the floating shaft 21. The third working channel 24 is tapered, and a centering device is provided on one side of the third working channel 24. The third working channel 24 is used to center and fix the floating shaft.

[0036] like Figure 5 As shown, it also includes a centering device and a locking drive device. The centering device is arranged on one side of the floating shaft 21 so that the floating shaft 21 is centered and fixed. The centering device includes a centering cone sleeve 251 and a centering cylinder 252 connected to the centering cone sleeve 251. The centering cone sleeve 251 is pushed into the third working channel 24 by the centering cylinder 252 to realize the centering and fixing of the floating shaft 21. The locking drive device includes a push rod 261 and a locking cylinder 262 connected to the push rod 261. The centering cone sleeve 251 is a hollow structure. The push rod 261 is movably arranged in the hollow structure. The push rod 261 is pushed by the locking cylinder 262 so that the push rod 261 contacts the sliding rod 231 to realize the extrusion of the locking buckle 221.

[0037] The working principle of this utility model:

[0038] like Figure 6As shown, the part 3 is installed on the clamping plate 21. In order to allow the floating shaft 21 to penetrate the part 3, the floating shaft 21 needs to be centered. At this time, the centering cone sleeve 251 is driven by the centering cylinder 252 to move and enter the third working channel 24 to center and fix the floating shaft 21. In this way, the part 3 can be installed smoothly.

[0039] like Figure 7 and 8 As shown, the parts need to be clamped after installation, and the locking cylinder 262 drives the push rod 261 to move, pushing the sliding rod 231 to extrude the locking buckle 221, thereby limiting and fixing the part 3.

[0040] like Fig. 9 As shown, the centering cone sleeve 251 is driven to leave the third working channel 24 by the centering cylinder 252, and the part 3 can be rotated by the rotating motor 11, so that the part 3 can be tightened, and the other parts assembled with the part 3 are not shown in the figure. At this time, the floating shaft 21 can float freely in the floating mounting cover 20, and the rotating device rotates to screw the external nut into the internal threaded pipe fitting.

[0041] like Fig.10 As shown, after tightening is completed, the locking cylinder 262 drives the push rod 261 to retreat, and under the action of the second spring 232, the sliding rod 231 returns to its position, and the locking buckle 221 returns to its position under the action of the first spring 222, thereby releasing the limit on the part 3, and the part 3 can be removed to complete the tightening.

[0042] The floating tightening mechanism of the utility model can realize the limited fixation of parts, the floating tightening of parts has wide adaptability, can reduce the processing error and assembly error of parts, and avoid damage to parts during assembly.
