[0002] At present, the welding of balance shaft products is mainly done manually, and multiple manual rotation and hoisting are required during the welding process. According to statistics, it takes 11-13 times of hoisting to weld a product.

[0040] The working principle and beneficial effects of the present invention are:

[0041] In the present invention, the frame is the basic supporting structure of the entire device, and the first support frame is rotatably arranged on the frame and has a mounting portion for mounting a tube body positioning member. The tube body positioning member is slidably arranged on the mounting portion of the first support frame and has a positioning groove for positioning the tube body. The positioned tube body can be rotated in the positioning groove to facilitate welding operations. Two shaft head positioning members are both arranged on the frame, respectively located on both sides of the tube body positioning member, and symmetrically arranged, and are used to fix the shaft head of the balance shaft. The frame body loading member is slidably arranged on the frame, located between the two shaft head positioning members, and is used to penetrate the frame body into the tube body after the shaft head welding is completed, and perform boat-shaped welding between the frame body and the tube body. The working process of this balance shaft welding positioner is as follows: place the tube body to be welded in the positioning groove of the tube body positioning member, and fix the tube body through the positioning groove. Adjust the angle of the first support frame so that the tube body is in a suitable welding position. Fix the shaft head of the balance shaft on both sides of the shaft head positioning member and abut against it to ensure the accurate position of the shaft head. The welding equipment is used to weld the joints between the tube body and the shaft head. During welding, the tube body and the shaft body rotate synchronously, and the welding equipment remains stationary. After welding is completed, the shaft head positioning piece cancels the fixation of the shaft head. When the first support frame rotates to the vertical position of the tube body, the frame loading piece passes the frame body onto the tube. After the first support frame rotates, the frame body and the tube body meet the ship-type welding requirements. The welding device moves to the welding point, rotates the tube body, and the frame body rotates with the tube body during welding to perform welding. After welding one side, the first support frame rotates half a circle (180 degrees) to perform welding on the other side. After processing is completed, remove the welded workpiece and repeat the above steps for the next welding. It should be noted that when the frame body is welded continuously after the shaft head welding, the clamping position of the tube body positioning piece is located on one side of the frame body installation position when the tube body is loaded, and the frame body is positioned by the tube body positioning piece. The advantage of this design is that it can flexibly adjust the position and angle of the tube body, is suitable for welding of balance shafts of various sizes and shapes, and improves welding efficiency and accuracy. At the same time, through the symmetrically arranged shaft head positioning parts and the slidable frame loading parts, different workpieces can be positioned and fixed more conveniently, ensuring stability and safety during welding. Compared with the balance shaft welding positioner in the prior art, the position and angle of the tube body can be more accurately controlled through the positioning groove and rotatable design of the tube body positioning parts, ensuring accurate alignment during welding. The symmetrically arranged shaft head positioning parts can fix the shaft head more stably, improve the stability during welding, and thus improve the welding accuracy. The pre-welding or spot welding steps to meet the fixing requirements on the welding positioner before the balance shaft welding are cancelled, which simplifies the welding process, saves time and cost, and can also meet the high-precision requirements of only one welding head when welding the balance shaft, with higher welding quality, and improves the quality and appearance accuracy of the balance shaft. Through the rotation of the first support frame and the sliding of the tube body positioning parts, the position of the tube body can be quickly adjusted, and a seamless transition from shaft head welding to frame welding is achieved, which improves production efficiency.Through precise positioning and fixing, deformation during welding can be reduced, and welding quality and appearance accuracy can be improved. After welding, no additional grinding or finishing process is required to correct the deviation caused by pre-welding or spot welding, which further improves the quality of the product. The slidable frame loading parts can easily adapt to the frame welding requirements of balance shafts of different sizes and shapes, improving the flexibility and applicability of the equipment. The sliding design of the tube body positioning parts and the rotating design of the first support frame enable the device to handle the welding requirements of different angles of the balance shaft, improving production efficiency and equipment utilization. By eliminating the pre-welding or spot welding steps, the operation process is simplified, the difficulty of operation is reduced, and the time and cost of maintenance and troubleshooting are also reduced.

[0058] Reference Figure 1 to Figure 10, as an embodiment of the present invention, a balancing shaft welding positioner is proposed, which is used for the joint welding of the shaft head 101 and the tube body 102 of the balancing shaft 1, and for the ship-shaped welding of the tube body 102 and the frame body 103, including: a frame 2, a first support frame 3 rotatably arranged on the frame 2, the first support frame 3 has a mounting portion 301, a tube body positioning member 4 is slidably arranged on the mounting portion 301, the tube body positioning member 4 has a positioning groove 401, the positioning groove 401 is used for positioning the tube body 102, the tube body 102 can rotate after being positioned in the positioning groove 401, a shaft head positioning member 5 is arranged on the frame 2, there are two shaft head positioning members 5, the two shaft head positioning members 5 are respectively located on both sides of the tube body positioning member 4, and are symmetrically arranged, and a frame loading member 6 is slidably arranged on the frame 2 and is located between the two shaft head positioning members 5.

[0059] In this embodiment, the frame 2 is the basic supporting structure of the entire device. The first support frame 3 is rotatably arranged on the frame 2 and has a mounting portion 301 for mounting the tube body positioning member 4. The tube body positioning member 4 is slidably arranged on the mounting portion 301 of the first support frame 3 and has a positioning groove 401 for positioning the tube body 102. The positioned tube body 102 can rotate in the positioning groove 401 to facilitate welding operations. Two shaft head positioning members 5 are both arranged on the frame 2, respectively located on both sides of the tube body positioning member 4, and symmetrically arranged, and are used to fix the shaft head 101 of the balance shaft 1. The frame loading member 6 is slidably arranged on the frame 2, and is located between the two shaft head positioning members 5, and is used to insert the frame 103 into the tube body 102 after the welding of the shaft head 101 is completed, and perform boat-shaped welding between the frame 103 and the tube body 102. The working process of the balance shaft welding positioner is as follows: place the tube body 102 to be welded in the positioning groove 401 of the tube body positioning member 4, and fix the tube body 102 through the positioning groove 401. Adjust the angle of the first support frame 3 so that the tube body 102 is in a suitable welding position. Fix the shaft head 101 of the balance shaft 1 on both sides of the shaft head positioning member 5 and abut against it to ensure that the position of the shaft head 101 is accurate. Use welding equipment to weld the interface between the tube body 102 and the shaft head 101. During welding, the tube body 102 and the shaft body rotate synchronously, and the welding equipment remains stationary. After welding is completed, the shaft head positioning member 5 cancels the fixation of the shaft head 101. When the first support frame 3 rotates to the vertical position of the tube body 102, the frame loading member 6 passes the frame body 103 onto the tube. After the first support frame 3 rotates, the frame body 103 and the tube body 102 meet the ship-type welding requirements. The welding device moves to the welding point, rotates the tube body 102, and the frame body 103 rotates with the tube body 102 during welding to perform welding. After welding one side, the first support frame 3 rotates half a circle (180 degrees) to perform welding on the other side. After the processing is completed, remove the welded workpiece and repeat the above steps for the next welding. It should be noted that when the frame body 103 is welded continuously after the shaft head 101 is welded, when the tube body 102 needs to be loaded, the clamping position of the tube body positioning member 4 is located on one side of the installation position of the frame body 103, and the positioning of the frame body 103 is achieved by the tube body positioning member 4. The advantage of this design is that it can flexibly adjust the position and angle of the tube body 102, is suitable for welding of balance shafts 1 of various sizes and shapes, and improves welding efficiency and accuracy. At the same time, through the symmetrically arranged shaft head positioning members 5 and the slidable frame material member 6, it is more convenient to position and fix different workpieces, ensuring stability and safety during the welding process. Compared with the balance shaft welding positioner in the prior art, the position and angle of the tube body 102 can be more accurately controlled through the positioning groove 401 and the rotatable design of the tube body positioning member 4, ensuring precise alignment during welding. The symmetrically arranged shaft head positioning members 5 can more stably fix the shaft head 101, improve stability during welding, and thus improve welding accuracy.The pre-welding or spot welding steps to meet the fixing requirements on the welding positioner before welding the balancing shaft 1 are cancelled, the welding process is simplified, time and cost are saved, and the balancing shaft 1 can also meet the high-precision requirements of only one welding head when welding, the welding quality is higher, and the quality and appearance accuracy of the balancing shaft 1 are improved. Through the rotation of the first support frame 3 and the sliding of the tube body positioning member 4, the position of the tube body 102 can be quickly adjusted to achieve a seamless transition from the welding of the shaft head 101 to the welding of the frame body 103, thereby improving production efficiency. Through precise positioning and fixing, the deformation during welding can be reduced, and the welding quality and appearance accuracy can be improved. After welding is completed, no additional grinding or finishing process is required to correct the deviation caused by pre-welding or spot welding, further improving the quality of the product. The slidable frame material 6 can easily adapt to the welding requirements of the frame body 103 of the balancing shaft 1 of different sizes and shapes, thereby improving the flexibility and applicability of the equipment. The sliding design of the tube body positioning member 4 and the rotation design of the first support frame 3 enable the device to handle the welding requirements of different angles of the balancing shaft 1, thereby improving production efficiency and equipment utilization. By eliminating the pre-welding or spot welding steps, the operation process is simplified and the operating difficulty is reduced, while also reducing the time and cost of maintenance and troubleshooting.

[0060] Furthermore, the tube body positioning member 4 also has an installation groove, the positioning groove 401 has an opening 402, and the tube body positioning member 4 also includes: a circulating V-belt 403, the circulating V-belt 403 is circulated and arranged in the installation groove, the circulating V-belt 403 forms the positioning groove 401, the outer surface of the circulating V-belt 403 abuts against the tube body 102, the inner surface of the circulating V-belt 403 has a tooth groove, the clamp 404 is swingably arranged on one side of the installation groove, and the clamp 404 opens or closes the opening 402 after swinging, and the circulating steel belt 405 is arranged on the clamp 404, and the circulating steel belt 405 is used to abut against the tube body 102, and the pulley 406 is rotatably arranged in the installation groove, and the pulley 406 is meshed with the tooth groove.

[0061] In this embodiment, the tube body positioning member 4 has a mounting groove, the positioning groove 401 has an opening 402, and the circulating V-belt 403 is circulated in the mounting groove to form the positioning groove 401. The outer surface of the circulating V-belt 403 abuts against the tube body 102, and the inner surface has a tooth groove. The circulating V-belt 403 abuts against the tube body 102 through its outer surface, and the tooth groove on the inner surface abuts against the pulley 406, which is used to fix the tube body 102 and rotate it. The clamp 404 is swingably set on one side of the mounting groove, and the opening 402 of the positioning groove 401 can be opened or closed by swinging, which is convenient for placing and removing the tube body 102, and is also used for fixing and locking the tube body 102. The circulating steel belt 405 is set on the clamp 404, which is used to abut against the tube body 102 to avoid friction between the tube body 102 and the clamp 404 when the tube body 102 rotates, affecting the finished product quality of the balance shaft 1. The pulley 406 is rotatably arranged in the mounting groove, and is meshed with the tooth groove on the inner surface of the circulating V-belt 403, so as to drive the circulating V-belt 403 to rotate. The tube body 102 to be welded is placed in the positioning groove 401 of the tube body positioning member 4, and the circulating V-belt 403 abuts against the tube body 102 through its outer surface, and then the clamp 404 swings, and the outer surface of the circulating steel belt 405 abuts against the tube body 102. The angle of the first support frame 3 is adjusted to make the tube body 102 in a suitable welding position. By abutting the outer surface of the circulating V-belt 403 with the tube body 102, and the abutting of the outer surface of the circulating steel belt 405 with the tube body 102, the tube body 102 can be fixed more accurately, ensuring the stability and safety during the welding process, and improving the welding quality and precision. The setting of the circulating steel belt 405 avoids direct contact between the tube body 102 and the clamp 404 when rotating, reduces the wear on the surface of the tube body 102, and improves the quality of the finished product. By reducing the wear on the surface of the tube body 102, product defects caused by surface scratches or damage can be avoided, and the appearance accuracy of the product is improved. The design of the clamp 404 makes the placement and removal of the tube body 102 more convenient, reducing the operation time and labor intensity. Through the swing of the clamp 404, the opening 402 of the positioning groove 401 can be easily opened or closed, which is convenient for loading and unloading the tube body 102. Through the use of the circulating V-belt 403 and the circulating steel belt 405, the position of the tube body 102 can be adjusted more quickly, which speeds up the welding process. The repositioning time caused by inaccurate fixation of the tube body 102 is reduced, and the production efficiency is improved. Through the use of the circulating V-belt 403 and the circulating steel belt 405, it can adapt to tube bodies 102 of different sizes and shapes, enhancing the flexibility of the equipment. The equipment can handle more types of balancing shafts 1, improving the applicability and production efficiency of the equipment. The design of the circulating V-belt 403 and the circulating steel belt 405 reduces the direct contact between the tube body 102 and the clamp 404, reduces the wear of the clamp 404, and reduces the maintenance frequency. By reducing maintenance needs, maintenance costs and downtime are reduced, and equipment availability and production efficiency are improved.Compared with the prior art, the balance shaft welding positioner improves the fixing accuracy of the pipe body 102 through the design of the circulating V-belt 403 and the circulating steel belt 405, reduces the wear of the pipe body 102, simplifies the operation process, improves production efficiency, enhances the flexibility of the equipment, and simplifies maintenance work. These improvements work together to improve production efficiency and product quality.

The design of the swinging member 503 can realize the rapid release of the shaft head 101 after the shaft body welding is completed, and meet the space requirements for the angle adjustment of the tube body 102. At this time, the sliding seat 501 slides and moves away from each other, further avoiding the interference between the shaft head positioning member 5 and the shaft head 101 when the first support frame 3 is adjusted in angle. The rotating member 504 enables the shaft head 101 and the tube body 102 to rotate synchronously without manual intervention, thereby reducing welding time and improving production efficiency.

The rotating shaft 602 is rotatably arranged on the lifting frame 601, and has a slide groove 603, and the slide groove 603 is along the axial direction of the rotating shaft 602. The material picking member 604 is slidably arranged in the slide groove 603 of the rotating shaft 602, and has a fork 605, and the fork 605 is used to fork the frame 103. When the fork 605 is located at the material picking position, the frame 103 is clamped on the fork 605 through the conveying structure. The sliding of the material picking member 604 can make the frame 103 move along the axis of the tube body 102, reduce the collision when the frame 103 is placed on the tube body positioning member 4, and avoid the damage of the frame 103 or the tube body positioning member 4 caused by the collision. By using the lifting frame 601, the rotating shaft 602 and the material taking piece 604 in combination, the loading and positioning of the frames 103 of different sizes can be conveniently performed, thereby improving the flexibility and efficiency of welding. The design of the material taking piece 604 ensures that the frame 103 is stably placed on the tube body positioning piece 4, thereby improving the quality of the finished product. The design of the lifting frame 601 can adjust the height of the material taking piece 604, thereby making it convenient to load the frames 103 of different sizes. By rotating the rotating shaft 602, the material taking piece 604 can be accurately positioned at the desired position, thereby improving the flexibility of material taking. The equipment can adapt to frames 103 of different sizes and shapes, thereby enhancing the applicability of the equipment. By sliding the material taking piece 604, the frame 103 can be quickly placed on the tube body positioning piece 4, thereby reducing the preparation time before welding. The design of the material taking piece 604 enables the operator to easily place the frame 103 on the tube body positioning piece 4, thereby reducing the difficulty of operation. By reducing the intervention of the operator, the possibility of operating errors is reduced, thereby improving production efficiency. By reducing the collision between the frame 103 and the tube body positioning member 4, the wear of the tube body positioning member 4 is reduced, and the maintenance frequency is reduced. By reducing the maintenance requirements, the maintenance cost and downtime are reduced, and the availability and production efficiency of the equipment are improved. It should be noted that the lower side of the material picking member 604 has an annular groove, and the driving end of the lifting drive member is slidably arranged in the annular groove, and the lifting and lowering of the material picking member 604 is driven by the lifting drive member.

[0066] Furthermore, the tube body positioning member 4 also has an arc groove 407, which is concentrically arranged with the tube body 102.

The second suction cup 410 abuts against the side wall of the transmission steel belt 411 and is used to be fixed with the transmission steel belt 411. The transmission steel belt 411 drives the first suction cup 409 to slide along the arc groove 407.

[0067] In this embodiment, the tube body positioning member 4 has an arc groove 407 concentrically arranged with the tube body 102, which is used to install the first suction cup 409 and the second suction cup 410. The first suction cup 409 is used to fix the frame 103, and the second suction cup 410 abuts against the side wall of the transmission steel belt 411, which is used to fix the first suction cup 409 and the transmission steel belt 411. The transmission steel belt 411 is sleeved on the pulley 406, and the second suction cup 410 abuts against the side wall of the transmission steel belt 411, driving the first suction cup 409 to slide along the arc groove 407. When the first suction cup 409 slides along the arc groove 407, the first suction cup 409 is oblique compared to the ground. The sliding direction can be understood here as the lifting direction.

Through the rotation of the transmission steel belt 411, the position of the frame 103 can be synchronously adjusted to meet the needs of the rotation welding of the tube body 102. Through the use of the first suction cup 409, the frame 103 can be quickly fixed and released, reducing the preparation time before welding and the disassembly time after welding. The design of the first suction cup 409 simplifies the placement process of the frame 103 and improves the welding efficiency. The design of the first suction cup 409 allows the operator to easily place the frame 103 on the tube body positioning member 4, reducing the difficulty of operation. By reducing the intervention of operators, the possibility of operating errors is reduced and production efficiency is improved. By reducing the collision between the frame 103 and the tube body positioning member 4, the wear of the tube body positioning member 4 is reduced, and the maintenance frequency is reduced. By reducing the maintenance requirements, the maintenance cost and downtime are reduced, and the availability and production efficiency of the equipment are improved.
