[0028] As shown in the embodiment, Figure 1 the column 1 is vertically placed and used for fixing the whole handheld laser welding head hanger mechanism on the column 1.
[0029] The rotating arm one 7 is horizontally placed, and the bottom surface of one end thereof is installed on the top surface of the column 1 through the horizontal rotating mechanism one and can rotate in the horizontal plane with the assistance of the horizontal rotating mechanism one.
[0030] The rotating arm two 11 is horizontally placed, and the end surface of one end thereof is connected to the other end of the rotating arm one 7 through the horizontal rotating mechanism two and can rotate in the horizontal plane with the assistance of the horizontal rotating mechanism two.
[0031] The bottom surface of the rotating arm two 11 is installed with the sliding hook hanger mechanism, and the sliding hook hanger mechanism can reciprocate back and forth along the length direction of the rotating arm two 11.
[0032] In other embodiments, as shown in the embodiment, Figure 1 , Figure 2 the horizontal rotating mechanism one comprises a bearing seat 2, a double-row angular contact bearing one 4, a bearing gland 5, and a rotating shaft one 6, which are introduced as follows.
[0033] The top surface of the column 1 is installed with the bearing seat 2. The double-row angular contact bearing one 4 is placed inside the bearing seat 2, and a fixed washer 3 is placed between the lower part of the double-row angular contact bearing one 4 and the inner bottom surface of the bearing seat 2. The bearing gland 5 is installed on the top surface of the bearing seat 2 and is located above the double-row angular contact bearing one 4. The rotating shaft one 6 is vertically inserted into the double-row angular contact bearing one 4, and the bottom surface of the rotating shaft one 6 downwardly penetrates the double-row angular contact bearing one 4 and is connected to the fixed washer 3, and the bottom surface of the rotating shaft one 6 upwardly penetrates the bearing gland 5 and is connected to the bottom surface of one end of the rotating arm one 7.
[0034] In specific implementation, the column 1 is used as a fulcrum, and since the rotating shaft one 6 is connected to the rotating arm one 7 and the fixed washer 3 at two ends thereof, the rotating shaft one 6 can rotate 360° in the double-row angular contact bearing one 4, so that the rotating arm one 7 connected to the rotating shaft one 6 and the rotating arm two 11 connected to the rotating arm one 7 can freely rotate 360° horizontally with the rotating shaft one 6 as the center.
[0035] In other embodiments, as shown in the embodiment, Figure 1 , Figure 3 the horizontal rotating mechanism two comprises a double-row angular contact bearing two 8, a rotating shaft two 9, a U-shaped bracket 17, and a nut 10, and the U-shaped bracket 17 comprises two branch ends and a connecting end, which are specifically introduced as follows.
[0036] The other end of the rotating arm one 7 is internally installed with a double row angular contact bearing two 8. The other end of the rotating arm one 7 is inserted between the two branches of a U-shaped support 17. The connecting end of the U-shaped support 17 is installed on the end face of one end of a rotating arm two 11. The rotating shaft two 9 vertically penetrates one branch of the U-shaped support 17, is inserted in the double row angular contact bearing two 8, and penetrates out of the other branch of the U-shaped support 17, and is fixedly connected with a nut 10 located below the U-shaped support 17.
[0037] In specific implementation, on the basis that the rotating arm two 11 can freely horizontally rotate 360° along with the rotating arm one 7, the rotating arm two 11 and the sliding hook lifting mechanism installed thereon can horizontally rotate around the rotating shaft two 9 through the rotating shaft two 9 inserted in the U-shaped support 17 and the double row angular contact bearing two 8 and the nut 10. Since the rotating arm two 11 will be blocked by the other end of the rotating arm one 7 during rotation, it cannot freely horizontally rotate 360° around the rotating shaft two 9, but can freely horizontally rotate 220° around the rotating shaft two 9.
[0038] As shown in Figure 1 The sliding hook lifting mechanism includes two fixed seats 12, a sliding rod 13, a linear bearing 14, a tension balancer 15, and an arc-shaped hanger 16, which are introduced as follows.
[0039] The two fixed seats 12 are installed at the two ends of the bottom surface of the rotating arm two 11 along the length direction of the rotating arm two 11. The sliding rod 12 is installed at the corresponding fixed seat 12 at each end. The linear bearing 14 is installed on the sliding rod 13. One end of the tension balancer 15 is installed on the linear bearing 14, and the other end of the tension balancer 15 is hung with the arc-shaped hanger 16.
[0040] In specific implementation, through the mutual fixation of the fixed seat 12, the sliding rod 13, and the linear bearing 14, the tension balancer 15 and the arc-shaped hanger 16 at the lower end of the tension balancer 15 can freely reciprocate along the length direction of the rotating arm two 11. Moreover, on the basis that the rotating arm one 6 can freely horizontally rotate 360° and the rotating arm two 11 can freely horizontally rotate 220°, since the arc-shaped hanger 16 is hung by the tension balancer 15, after the arc-shaped hanger 16 hangs articles, the freely stretching hook lifting function in the up-down or front-back and left-right directions can be realized through tension, and the size of the tension can be adjusted through the knob of the tension balancer 15.
[0041] In summary, the working process of the utility model is as follows: firstly, since the rotating arm one 7 is fixed on the top surface of the stand column 1 through the bearing seat 2, the double-row angular contact bearing one 4, the bearing pressure cover 5, the fixed gasket 3 and the like, can make horizontal rotation 360 ° movement, at the same time, since the rotating arm two 11 is fixed on the other end of the rotating arm one 7 through the double-row angular contact bearing two 8, the rotating shaft two 9, the U-shaped support 17, the nut 10 and the like, can make horizontal rotation 220 ° movement, therefore, the rotating operation is carried out to the rotating arm one 7 and the rotating arm two 11 respectively, and the rotating arm one 7 and the rotating arm two 11 are quickly and simply adjusted according to the target working position, the working efficiency is improved. Then, since the arc-shaped hanging bracket 16 is fixed on the bottom surface of the rotating arm two 11 through the tension balancer 15, the linear bearing 14, the sliding rod 13 and the fixed seat 12, can realize the movement of free stretching and hooking, therefore, the arc-shaped hanging bracket 16 is freely stretched in the high-low or front-back and left-right direction, to reach the target working position, it is more convenient to use. And, the knob of the tension balancer 15 is adjusted, the tension size is realized, the working process is facilitated.
