[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0028] During the assembly process of large products, it is usually necessary to assemble both sides of the product. In the prior art, two operators are usually assigned to operate on both sides of the operation line to realize the assembly operation on both sides of the product.

[0029] However, this arrangement requires two operators at the same time. Under the current situation of tight human resources and high costs, adding one more operator will greatly increase labor costs.

[0030] Based on this, an exemplary embodiment of the present application provides a rotary jacking mechanism, in which a jacking drive unit, a rotating assembly and a telescopic locking assembly are provided. The jacking drive unit can drive the rotating assembly to lift and lower, and the rotating assembly can rotate under the action of external force to drive the workpiece placed on the rotating assembly to rotate. After rotating by a preset angle, the rotating assembly can be fixed by the telescopic locking assembly to prevent the rotating assembly from moving during operation. In this way, when assembling large products, the workpiece can be rotated by a preset angle according to the needs of workpiece assembly to assemble other parts of the workpiece. There is no need to set operators on multiple sides of the workpiece, saving manpower and labor costs.

[0031] An exemplary embodiment of the present application provides a rotary lifting mechanism, such as Figures 1 to 4 As shown, the rotary lifting mechanism includes a lifting drive unit 10, a first support plate 20, a second support plate 30, a rotating assembly 40 and a telescopic locking assembly 50; wherein, the lifting drive unit 10 is arranged at the bottom of the first support plate 20, and the lifting drive unit 10 is preferably a cylinder, and the protruding end of the lifting drive unit 10 passes through the first support plate 20 and abuts against the second support plate 30; the top of the second support plate 30 is provided with a rotating assembly 40; the telescopic locking assembly 50 is arranged on one side of the rotating assembly 40. The telescopic locking assembly 50 can be extended and retracted to release or fix the rotating assembly 40; when the telescopic locking assembly 50 is extended, the rotating assembly 40 can be fixed to prevent the rotating assembly 40 from rotating during the assembly process of the workpiece by the operator; when the workpiece needs to be rotated to a certain angle to assemble other sides, the telescopic locking assembly 50 can be retracted, and at this time, under the action of external force, the rotating assembly 40 can rotate a preset angle.

[0032] In one embodiment, if Figure 5 As shown, the rotating assembly 40 includes a slewing bearing 401, a rotating ring 402 and a rotating plate 403; the slewing bearing 401 is arranged on the second support plate 30; the rotating plate 403 is arranged on the slewing bearing 401 and connected to the outer ring of the slewing bearing 401; the rotating ring 402 is sleeved outside the slewing bearing 401, and the top is fixedly connected to the bottom of the rotating plate 403. When rotating, an external force can be manually applied to the rotating plate 403, and then the rotating plate 403 can drive the rotating ring 402 and the workpiece to rotate together. A positioning part for positioning the workpiece is also provided on the top of the rotating plate to fix or position the workpiece to prevent the workpiece from moving or rotating during operation.

[0033] In order to facilitate the fixing of the rotating assembly 40 and prevent the rotating assembly 40 from rotating due to external force during the workpiece assembly process, at least two positioning grooves 4021 are provided on the circumferential surface of the rotating ring 402. When the rotating assembly 40 needs to be fixed, the telescopic locking assembly 50 can be clamped in the positioning groove 4021. In order to adapt to various working conditions, four positioning grooves 4021 are provided on the circumferential surface of the rotating ring, and the four positioning grooves 4021 are evenly distributed on the circumferential surface of the positioning ring, so that the rotating assembly 40 can be positioned every 90° rotation.

[0034] like Figure 6 As shown, the telescopic locking assembly 50 includes a locking drive unit 501, a locking fixed seat 502 and a telescopic unit 503; the locking fixed seat 502 is arranged on the second support plate 30, the locking drive unit 501 is arranged at the end of the locking fixed seat 502 away from the rotating assembly 40, and one end of the telescopic unit 503 is connected to the protruding end of the locking drive unit 501; the locking drive unit 501 drives the telescopic unit 503 to reciprocate in the locking fixed seat 502. The telescopic unit 503 includes a connecting shaft group 5031, a first elastic element 5032 and a telescopic pin 5033; one end of the connecting shaft group 5031 is connected to the protruding end of the locking drive unit 501, and the other end is connected to the telescopic pin 5033; the first elastic element 5032 is sleeved on the connecting shaft group 5031, and preferably, the first elastic element 5032 is a spring. The locking drive unit 501 is preferably a cylinder, which can drive the telescopic unit 503 to reciprocate along the locking fixed seat 502 to move away from or into the positioning groove 4021.

[0035] In order to facilitate the rotation of the rotating ring 402 , the telescopic unit 503 further includes a rolling member 5034 . The rolling member 5034 is disposed at the end of the telescopic pin 5033 . The rolling member 5034 may be a bearing or a roller to roll on the circumferential surface of the rotating ring 402 .

[0036] like Figure 2 As shown in FIG. 3 , a sensor assembly 60 is further provided on the other side of the rotating assembly 40, and the sensor assembly 60 is provided on the second supporting plate 30. The detection extension direction of the sensor assembly 60 is in the same straight line as the extension direction of the telescopic locking assembly 50. When the rotating assembly 40 rotates, the sensor assembly 60 can detect the position of the positioning groove 4021. If the positioning groove 4021 is not detected, the detection signal is transmitted to the control system, and the control system controls the telescopic locking assembly 50 to extend, and the rolling element 5034 is attached to the circumferential surface of the rotating ring 402 and rolls along the circumferential surface of the rotating ring 402. When the rolling element 5034 rolls to the positioning groove 4021, the telescopic locking assembly 50 continues to extend a distance, and the rolling element 5034 is engaged in the positioning groove 4021 to fix the rotating assembly 40.

[0037] In one embodiment, in order to guide the lifting and recovery of the rotating assembly 40, as shown in FIG. Figure 5 As shown in FIG. 7 , the rotary lifting mechanism further includes a guide assembly 70 , which passes through the first support plate 20 , and a top of the guide assembly 70 is fixedly connected to a bottom of the second support plate 30 .

[0038] In one embodiment, in order to achieve unidirectional rotation of the rotating assembly 40, as shown in FIG. Figure 7 and 8 As shown, the rotary lifting mechanism also includes a check assembly 80, which is arranged on one side of the second support plate and is used to limit the rotation direction of the rotating assembly 40. The check assembly 80 includes a housing 801 and a second elastic element 803 arranged in the housing 801. The second elastic element 803 is preferably a spring. A locking tongue 802 is arranged on the top of the second elastic element 803. The locking tongue 802 has an inclined top surface. The locking tongue 802 of the check assembly 80 is clamped in the positioning groove 4021. When the rotating assembly 40 moves to the left, the locking tongue 802 is locked in the positioning groove 4021. Figure 8 When rotating in the direction of the middle arrow, the rotating ring can gradually press the locking tongue 802 downward along the inclined surface of the locking tongue 802 to realize the rotation of the rotating assembly 40; Figure 8 When rotating in the direction opposite to the middle arrow, the locking tongue 802 can stop the rotation of the rotating ring 402 to achieve unidirectional rotation of the rotating assembly 40 .

[0039] The working process of the rotary lifting mechanism of the present application is as follows: when the workpiece needs to be rotated, the control system controls the locking drive unit 501 to drive the telescopic unit 503 to retract, and manually rotates the rotating component 40. During this process, the sensor component 60 detects whether the positioning groove 4021 is within the detection range. If the positioning groove 4021 is not within the detection range, the locking drive unit 501 drives the telescopic unit 503 to extend, and the rolling element 5034 rolls against the circumferential surface of the rotating ring 402. After the rolling element 5034 rolls into the positioning groove 4021, it is clamped in the positioning groove 4021 to fix the rotating component 40.
