The lifting device controls the lifting and lowering of the operation platform. The worktable can be flipped to realize the interchange of the upper and lower positions of the fillet welding auxiliary fixtures and the butt welding auxiliary fixtures. The height of the worktable is adjustable. The worktable can realize the position change of the auxiliary fixtures for butt welding and fillet welding, and has strong operability.

[0004] Existing technology only sets up a platform for the welding device to move up and down. When dealing with the welding of some shaft-type workpieces, most of the shaft-type workpieces are placed horizontally, making it difficult to perform welding operations. Moreover, there is a lack of a mechanism to fasten the shaft-type workpieces, making it difficult to ensure the stability of the position of the shaft-type workpieces during welding.

[0005] Therefore, an adjustable laser welding fixture platform is proposed. Summary of the Invention

[0031] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1 An adjustable laser welding fixture platform includes a base 1, a robotic arm 2 mounted on the top of the base 1, a laser welding head 3 mounted on the movable end of the robotic arm 2, and a pair of shaft-type workpiece clamping components 4 symmetrically mounted on the top of the base 1 near the outer side of the robotic arm 2.

[0033] The shaft workpiece clamping component 4 can be used to fasten, transport and rotate shaft workpieces, and the laser welding head 3 can be used to perform laser welding operations on the joint of two shaft workpieces.

[0034] Reference Figures 1-7 The shaft workpiece clamping component 4 includes: a welding platform 43 and a shaft workpiece clamping and positioning unit 45. The shaft workpiece clamping and positioning unit 45 is installed at the top of the welding platform 43 and is used to clamp and position the shaft workpiece.

[0035] The shaft workpiece fastening and positioning unit 45 includes: a bearing seat 4501, a connecting plate 4502, a support ring 4510, and fastening modules 4504. The outer surface of the support ring 4510 is fixedly connected to the bearing seat 4501 via the connecting plate 4502. The connecting plate 4502 has two pairs and is circumferentially and equally spaced on the outer surface of the support ring 4510. The fastening modules 4504 have two pairs for fastening the shaft workpiece. The two pairs of fastening modules 4504 are installed on the inner surface of the support ring 4510 and are opposite to the connecting plate 4502.

[0036] The fastening module 4504 installed on the inner surface of the support ring 4510 in the shaft workpiece fastening and positioning unit 45 is moved, thereby adjusting the two pairs of fastening modules 4504 to move closer or further apart, so as to achieve the purpose of fastening shaft workpieces of various specifications.

[0037] Reference Figure 5 and 7An adjustment module is installed on the connecting plate 4502 to adjust the distance between the two pairs of fastening modules 4504. The adjustment module includes: a connecting rod A4503, a pair of lead screws 4505, a linkage plate A4506, an umbrella disc B4511, a rotating disc A4507, a rotating disc B4508, and an umbrella disc A4509. The front connecting plate 4502 is connected to the upper connecting plate 4502 via a slewing bearing and lead screws 4505. Two pairs of linkage plates A4506 are installed. The threads on both sides of the lead screws 4505 run in opposite directions. Each end of a pair of lead screws 4505 with opposite thread directions is threaded to a linkage plate A4506. A connecting rod A4503 is installed on one side wall of each pair of linkage plates A4506. One end of the connecting rod A4503 passes through the support ring 4510 and is fixed to the fastening module 4504 for traction. The upper end of the lead screw 4505 at the front of the fastening module 4504 is fixed to the umbrella disc B4511. The outer surface of the umbrella disc B4511 has a pre-drilled tooth four. The lower end of the lead screw 4505 at the front passes through the bearing seat 4501 and extends downward. The front end of the upper lead screw 4505 is fixed to the rotating disk A4507. The outer surface of the rotating disk A4507 has a pre-drilled tooth one. The inner surface of the bearing seat 4501 rotates the rotating rod via the slewing bearing. The outer surfaces of the rotating rods are fixed to the rotating disk B4508 and the umbrella disc A4509. The outer surface of the umbrella disc A4509 has a pre-drilled tooth three. The outer surface of the rotating disk B4508 has a pre-drilled tooth two. The rotating disk A4507 and the rotating disk B4508 are engaged with each other via tooth one and tooth two. The umbrella disc B4511 and the umbrella disc A4509 are engaged with each other via tooth three and tooth four.

[0038] By rotating the front lead screw 4505 in the rotary adjustment module, the upper and lower pair of linkage plates A4506 can be pulled closer or further apart. Through the meshing action between umbrella plate B4511 and umbrella plate A4509, and the meshing action between rotating plate A4507 and rotating plate B4508, power transmission is achieved. The upper lead screw 4505 can be rotated simultaneously, which in turn pulls the front and rear pair of linkage plates A4506 closer or further apart. This adjusts the position of the fastening module 4504 installed at one end of the connecting rod A4503 to fasten the shaft-type workpiece.

[0039] Reference Figure 5 and Figure 6 The fastening module 4504 includes: a concave connecting plate 45041, a connecting rod B45042, an arc plate 45043, and a constraint rod 45044. The arc plate 45043 is provided in pairs, and each pair of arc plates 45043 is screwed onto the outer surface of the connecting rod B45042 for rotational adjustment and fastening of shaft-like workpieces. The two sides of the concave connecting plate 45041 are respectively fixed to the connecting rod A4503 and the connecting rod B45042, and the connecting rod A4503 is located on one side of the connecting rod B45042.

[0040] By rotating a pair of arc-shaped plates 45043 in the fastening module 4504 around the connecting rod B45042, and then adjusting the opening angle of the pair of arc-shaped plates 45043 during fastening, they can fully abut against the outer surface of the shaft workpiece, increasing the resistance between them. Furthermore, the rotation of the fastening module 4504 can be constrained by the constraint rod 45044, thereby ensuring stability during adjustment.

[0041] Reference Figure 6 The fastening module 4504 also includes: a connecting frame 45045, a rotating column A 45046, a rotating plate 45047, a rotating column B 45048, and a rotating roller B 45049. A pair of connecting frames 45045 are provided, and both pairs of connecting frames 45045 are installed on the inner surface of the arc plate 45043. The rotating column A 45046 is screwed onto the outer surface of the connecting frame 45045. A pair of rotating plates 45047 are provided, and both pairs of rotating plates 45047 are installed on the outer surface of the rotating column A 45046. The rotating column B 45048 is screwed onto the outer surface of the pair of rotating plates 45047. The rotating roller B 45049 is screwed onto the outer surface of the rotating column B 45048 and is used to tightly adhere to the outer surface of the shaft workpiece.

[0042] The rotating roller B45049 and rotating column B45048 rotate around the rotating plate 45047, and the rotating plate 45047 rotates around the rotating column A45046, thereby achieving the purpose of rotation. When the rotating roller B45049 and the shaft workpiece come into contact, the optimal contact range can be generated, achieving a firm and tight fastening effect.

[0043] Refer to 2. Figure 3 and Figure 4 The upper end of the welding platform 43 is equipped with a shaft workpiece translation unit 44 for conveying shaft workpieces. The shaft workpiece translation unit 44 includes: an arched seat 4401, a hollow outer column 4402, and a lifting inner column 4403. The hollow outer column 4402 is fixed to the inside of the arched seat 4401, and the lifting inner column 4403 is embedded in the inner surface of the hollow outer column 4402. The upper end of the lifting inner column 4403 passes through the arched seat 4401 and is installed at the upper end of the lifting inner column 4403 to convey shaft workpieces.

[0044] The shaft workpiece is transported via a lifting inner column 4403 that can move up and down inside the hollow outer column 4402 in the shaft workpiece translation unit 44, and a conveying module installed on the upper end of the lifting inner column 4403. The shaft workpiece is then adjusted at the welding point of the shaft workpiece to achieve self-adjustment and improve the welding speed.

[0045] Refer to 3 and Figure 4The conveying module includes: a concave opening 4404 and a rotating roller A4405. The concave opening 4404 is installed at the upper end of the lifting inner column 4403, and three rotating rollers A4405 are installed. All three rotating rollers A4405 are screwed onto the inner surface of the concave opening 4404.

[0046] The rotating roller A4405 installed on the inner surface of the U-shaped groove can pull and transport shaft-type workpieces by rotating, thereby adjusting the welding position of the shaft-type workpieces.

[0047] Refer to 3 and Figure 4 The shaft workpiece translation unit 44 also includes: an inclined column 4406, a rotating column C4407, and a pull column 4408. The inclined column 4406 is fixed to the inner surface of the arched seat 4401. One side of the rotating column C4407 is screwed to the upper end of the inclined column 4406. A spring is installed at the connection between the rotating column C4407 and the inclined column 4406. One side of the pull column 4408 is embedded in the inner surface of the rotating column C4407. The other side of the pull column 4408 is fixed to the conveying module.

[0048] The inclined columns 4406 installed on both sides of the hollow outer column 4402, and the rotating column C4407 can be rotated by the deformation of the spring. Then, the pull column 4408 moves inside the rotating column C4407, thereby adjusting the position of the conveying module at one end of the pull column 4408. This ensures that the conveying module abuts against the outer surface of the shaft workpiece, thereby fastening the multi-specification shaft workpiece and ensuring the stability of the shaft workpiece during transport.

[0049] Reference Figure 4 Inside the hollow outer column 4402 and the rotating column C4407, there is a spiral beryllium copper wire 4409, which is used to pull the pull column 4408 and the lifting inner column 4403 to approach the shaft-like workpiece.

[0050] The spiral beryllium copper wire 4409 can pull the pull column 4408 and the lifting inner column 4403 to move closer to the shaft workpiece, and then match the shaft workpiece of various specifications.

[0051] Reference Figure 4 A motor is installed on the outer surface of the concave opening 4404 in the conveying module on the lifting inner column 4403. There are three rotating rollers A4405, which are linked by chains and sprockets.

[0052] Driven by a motor, the rotating roller A4405 can rotate simultaneously with the linkage of the chain and sprocket, which increases the contact resistance between shaft-type workpieces and the rotating roller A4405, ensuring the conveying effect.

[0053] (The terms "front", "upper", and "lower" used above are defined based on the perspective of the accompanying drawings in the instruction manual.)

[0054] Working principle: When welding shaft-type workpieces, after placing the shaft-type workpiece on the fastening module 4504, the screw 4505 is rotated to separate the rotating roller B45049 from the shaft-type workpiece, and the rotating roller A4405 abuts against the shaft-type workpiece. After the motor is started, the motor pulls the central rotating roller A4405 of the three sets of rotating rollers A4405 to rotate. Through the linkage of the chain and sprocket, the three sets of rotating rollers A4405 rotate simultaneously. At this time, the tilt angle of the rotating column C4407 on one side of the inclined column 4406 on both sides of the rotating roller A4405 can be adjusted with the help of the spring, so that the rotating rollers A4405 on both sides can fully abut against the outer surface of the shaft-type workpiece, achieving the cooperation and support of the left and right sides of the shaft-type workpiece and enhancing stability.

[0055] After the shaft-like workpiece is transported to the required welding position, rotating the lead screw 4505 pulls the two connecting plates A4506 closer together, causing the connecting rods A4503 on the outer surface of the connecting plates A4506 to come closer together. Next, the fastening modules 4504 are pulled closer together, achieving fastening on both sides of the shaft-like workpiece. At this time, the umbrella disc B4511 at the upper end of the lead screw 4505 pulls the umbrella disc A4509 to rotate. Then, the rotating rod pulls the rotating disc B4508 to rotate, causing the rotating disc A4507 to rotate, pulling the upper lead screw 4505 to rotate, bringing the remaining pair of connecting plates A4506 closer together. This allows the fastening modules 4504 on both sides of the connecting rods A4503 to fully abut against both sides of the shaft-like workpiece, ensuring the firmness of the fastening.

[0056] When the fastening modules 4504 approach each other, the rotating roller B45049 abuts against the outer surface of the shaft workpiece, and the rotating column B45048 is screwed onto the rotating plate 45047 to achieve rotation. Then, it presses the rotating column A45046 on the other side to rotate. Adjusting the included angle, the rotating roller B45049 fully abuts against the outer surface of the shaft workpiece. At this time, after pressing a pair of arc plates 45043, the pair of arc plates 45043 can rotate around the connecting rod B45042 to achieve the function of fastening multi-specification shaft workpieces and ensure the stability of the fastening. Finally, by using the external traction, the rotating roller B45049 can be pulled to rotate, thereby making the shaft workpiece rotate, and the circumferential rotation of the shaft workpiece can be used for welding.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
