At the same time, the fixture is directly exposed to the outside world when not in use, which can easily cause damage to the fixture, making it impossible to stably use for the subsequent clamping work of the vacuum joint, thereby affecting the welding efficiency of the vacuum joint.

[0028] The utility model provides Figure 1 A laser welding fixture shown includes a fixing mechanism 1 and further includes:

[0029] The clamping mechanism 2 is arranged on the top of the fixing mechanism 1 and is used to clamp and fix the vacuum joint;

[0030] The protection mechanism 3 is arranged on the outer side of the clamping mechanism 2 and is used to protect the clamping mechanism 2 when it is not in operation.

[0031] In order to conveniently clamp and weld the vacuum joint, Figure 2 and Figure 4 As shown, the clamping mechanism 2 includes five support shafts 201 and a first motor 203. The five support shafts 201 are equidistantly arranged on the outer wall of one side of the fixing mechanism 1. The outer walls of one side of the five support shafts 201 are all fixedly sleeved with driven gears 202, and two adjacent driven gears 202 are meshed. The first motor 203 is arranged on the inner wall of the other side of the fixing mechanism 1. The output end of the first motor 203 is fixedly installed with a driving gear 204, and the driving gear 204 is meshed with one of the driven gears 202. The outer side of the support shaft 201 is movably sleeved with a plurality of limiting seats 205 for fixing the vacuum joint. The limiting seat 205 is sleeved on the outer side of the support shaft 201 to place and limit the vacuum joint, so that the vacuum joint remains stable on the outer side of the support shaft 201. The first motor 203 works through the meshing action between the driving gear 204 and the driven gear 202 and the meshing action between the two adjacent driven gears 202, so that the multiple support shafts 201 rotate, and the welding position of the vacuum joint can be adjusted.

[0032] In order to conveniently protect the clamping mechanism 2 in the non-working state, Figure 2 and Figure 5 As shown, the protection mechanism 3 includes a rotating shaft 301, which is arranged on the outer wall of one side of the fixing mechanism 1, and a second motor 302 is arranged at the bottom of the rotating shaft 301. A rotating plate 303 is fixedly sleeved on the outer side of the top of the rotating shaft 301, and traction plates 304 are rotatably installed on both ends of the top of the rotating plate 303. Protective covers 305 are rotatably installed on the top of the two traction plates 304 away from the rotating plate 303. The second motor 302 works to rotate the rotating shaft 301, and then rotates the rotating plate 303. Under the traction action of the two traction plates 304, the two protective covers 305 can be driven to move to the outside of the multiple support shafts 201, so that they can protect the outside of the clamping mechanism 2.

[0033] In order to facilitate the installation of the clamping mechanism 2 and the protective mechanism 3, Figure 2 and Figure 3 As shown, the fixing mechanism 1 includes a fixed base plate 101, a fixing frame 102 is fixedly installed on the top of the fixed base plate 101, a control box 103 is movably installed on the outer wall of one side of the fixing frame 102, and the inner wall of the control box 103 is fixedly connected to the first motor 203. The fixed base plate 101 can install and fix the fixing frame 102 and the control box 103, and the control box 103 can install and protect the first motor 203.

[0034] In order to conveniently install the clamping mechanism 2, Figure 2-4 As shown, the inner wall of the fixed frame 102 is rotatably connected to the five support shafts 201, and the five driven gears 202 are arranged on the inner side of the fixed frame 102. A movable groove 104 is provided on the outer wall of the fixed frame 102 on the side away from the control box 103. The fixed frame 102 can install and fix the support shaft 201, thereby keeping the support shaft 201 stable during rotation.

[0035] In order to keep the protective cover 305 stable during the movement, Figure 2-3 and Figure 5 As shown, a slider 306 is fixedly installed on the bottom of one side of the two protective covers 305, and the outer walls of the two sliders 306 are movably connected to the inner walls of the two ends of the movable groove 104 respectively. The two protective covers 305 are arranged on the outside of multiple support shafts 201, and the movable groove 104 can limit the movement of the slider 306, so that the protective covers 305 remain stable during the movement, thereby enabling them to stably protect the support shaft 201 and the limiting seat 205.

[0036] In order to provide power for the movement of the protective cover 305, as Figure 2-3 and Figure 5 As shown, the top of one side of the fixed base plate 101 is rotatably connected to the rotating shaft 301, and the top of one side of the fixed base plate 101 is fixedly connected to the second motor 302. The second motor 302 is connected to the rotating shaft 301 through an output shaft transmission connection. The fixed base plate 101 can install and fix the rotating shaft 301 and the second motor 302. The operation of the second motor 302 causes the rotating shaft 301 to rotate, and then under the traction action of the rotating plate 303 and the traction plate 304, the two protective covers 305 can be driven to expand or retract.

[0037] In order to stabilize the vacuum joint by the limiting seat 205 on the outside of the support shaft 201, Figure 2 and Figure 4 As shown, a cap 206 is threadedly sleeved on the outer side of one end of the support shaft 201 away from the driven gear 202, and the cap 206 is abutted against the inner wall of an adjacent vacuum joint. The cap 206 can abut against the adjacent vacuum joint, thereby allowing multiple limiting seats 205 and adjacent vacuum joints to abut against each other, so that the vacuum joint remains stable on the outer side of the support shaft 201.

[0038] When laser welding the vacuum joint, the vacuum joint is inserted into the inner wall of the limiting seat 205, and then multiple limiting seats 205 are sequentially sleeved on the outer side of the support shaft 201, so that the limiting seat 205 can be connected with the adjacent vacuum joint, and then the head 206 can be used to seal the outer wall of one side of the support shaft 201 and to contact the adjacent vacuum joint, so that the limiting seat 205 and the vacuum joint can remain stable on the outside of the support shaft 201, and then the vacuum joint can be laser welded by the laser welding arm, and at the same time, the first motor 203 works to rotate the driving gear 204, and through the meshing action between the gear parts, the adjacent driven gear 202 is rotated, and at the same time, through the meshing action between the two adjacent driven gears 202, the five support shafts 201 are rotated, and then the vacuum joint on the outside can be driven to rotate, so that the laser welding arm can be used for different positions of the vacuum joint. The complete welding work can improve the welding efficiency of the vacuum joint. After the welding is completed, the vacuum joint after welding is detached from the outside of the support shaft 201, and then the second motor 302 is operated to make the rotating shaft 301 rotate, and then the rotating plate 303 is rotated, and then under the traction of the two traction plates 304, the two protective covers 305 can be driven to move relative to each other, so that the two protective covers 305 can protect the support shaft 201 and the limiting seat 205. At the same time, the movable groove 104 can limit the movement of the two sliders 306, so that the protective cover 305 remains stable during the movement, and then the protective cover 305 can stably protect the clamping mechanism 2, and the clamping mechanism 2 can be prevented from being exposed to the outside world and damaged when not in use. This embodiment specifically solves the problem that it is impossible to conveniently weld multiple vacuum joints in the prior art, and the clamp is easily damaged when exposed to the outside world when not in use.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
