[0041] Display module 17;

[0042] The display module 17 is integrated with the control device 14 or the display module 17 is a handheld device.

[0043] It should be noted that if Figure 1 The display module 17 and the control device 14 are preferably integrated and located on one side of the bracket 3. The display module 17 and the control device 14 are integrated into a display control device; or Figure 4 The display module shown is a handheld device connected to the bracket of the tightening tool 7. The connecting cable of the display module 17 and the control device 14 is routed through the inside of the polished rod. While ensuring the convenience of operation, the battery and the control device 14 with large volume and weight are placed at the far end, and the display module 17 is placed near the tightening tool 7 without exposed cables. The display module 17 is replaced according to actual needs.

[0044] Specifically, the ultrasonic monitoring tightening workstation of the present invention further includes:

[0045] Balancer 12;

[0046] The balancer 12 is located below the camera 1 , and is connected to the internal circuit of the camera 1 and the signal line 9 of the ultrasonic signal sleeve 6 .

[0047] It should be noted that the balancer 12 is connected to the internal lines of the control device 14 and the tightening tool 7. When working, it always maintains a relatively static state through the monitoring of the camera 1 and the balancer 12, avoiding the risk of cable breakage caused by position adjustment operation, improving the convenience of operation, and the internal wiring improves the appearance of the workstation.

[0048] Optionally, the signal line conduit 11 and the support 13 are both hollow structures.

[0049] It should be noted that the tightening tool 7 and the tightening tool 7 are both internally routed through the hollow structure of the signal line conduit 11, and the balancer 12, the control device 14 and the camera 1 are all internally routed through the hollow structure of the support 13.

[0050] Specifically, the working part of the tightening tool 7 is connected to the ultrasonic signal sleeve 6;

[0051] The tightening tool 7 is electrically connected to the control device 14 through the signal line conduit 11 of the bracket 3 .

[0052] It should be noted that the working part of the tightening tool 7 is connected to the signal interface of the ultrasonic signal sleeve 6, and the signal transmitted by the ultrasonic signal sleeve 6 is monitored when the tightening tool 7 is working. The ultrasonic signal sleeve 6 is an ultrasonic signal acquisition device; the tightening tool 7 is electrically connected to the control device 14 through the signal line conduit 11, which ensures that the control device 14 can prompt the next bolt position after the tightening tool 7 completes the tightening of a signal bolt to reach the set value, and continue until the tightening operation of all screws is completed.

[0053] Optionally, the ultrasonic signal sleeve 6 is fixedly connected to the assembly object 16 via a plurality of bolts 8 .

[0054] It should be noted that when the ultrasonic signal sleeve 6 is working, the ultrasonic signal sleeve 6 is fixedly connected to the assembly object 16 through a plurality of bolts 8, and the bolt heads of the plurality of bolts 8 are processed by ultrasonic patch. Here, any one of the plurality of bolts 8 corresponds to the assembly object 16 one by one; the positioning of any one of the plurality of bolts 8 is transmitted to the control device 14 by acquiring the bolt coordinates through the camera 1.

[0058] like Figure 3 As shown, the balance arm of the balancer 12 is used to fix the tightening tool 7, and a hole is opened in the center of the axis of the balance arm of the balancer 12 to run the signal line 9, and the tightening tool 7, the control device 14 and the internal wiring of the ultrasonic signal sleeve 6 are connected together by passing through the support 13 and the signal line conduit 11, thereby ensuring the monitoring and control function of the control device 14 during operation, and the balancer 12 is always maintained in a relatively static state during operation, avoiding the risk of cable breaking caused by position adjustment operation.

[0059] Specifically, the workflow of the ultrasonic monitoring tightening workstation of the present invention is as follows: the components to be assembled are fixed on the second workbench 15 through the pressure plate; the object to be tightened is selected in the control device 14, and the software of the control device 14 will prompt the tightening sequence, tightening steps, tightening speed, etc. of the bolts to be tightened. Before tightening at each position, the camera 1 takes a photo of the assembly components and transfers the photo to the control device 14; the control device 14 determines the correctness of the tightening sequence and steps according to the predetermined program and the screw position identified by the camera; the ultrasonic signal sleeve 6 is tightened by the tightening tool 7 according to the prompted tightening sequence, i.e., the tightening speed and other requirements.

[0060] After one of the plurality of bolts 8 is tightened to a set value, the control device 14 prompts the next bolt position of the plurality of bolts 8 until all the screws are tightened. Each time a screw is tightened, a line is drawn and marked, and the camera 1 records a photo of the distribution of the screws with the marked line after tightening, and uploads it to the control device 14.

[0061] In summary, the embodiments of the present invention can realize intelligent error-proof ultrasonic monitoring of tightening work; and by reasonably integrating the tightening tool, ultrasonic signal sleeve, control device, camera, and work platform, intelligent assembly tightening operation through camera positioning is realized; and the tightening tool, the control device, and the camera all adopt a concealed wiring layout, avoiding the inconvenience of tightening work caused by the connection of the existing ultrasonic monitoring device.

[0062] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary personnel in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications are also within the scope of protection of the present invention.
