Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and more specifically, to a straight seam welding fixture for coiled products. Background Technology

[0002] The straight seam welding fixture for coil products is a special auxiliary equipment designed specifically for the straight seam welding process of coils. Its core function is to ensure stable connection and neat weld seam of coils during the welding process through mechanical structures such as precise positioning, clamping and conveying. At the same time, it can achieve efficient production in conjunction with automated mechanisms. It is widely used in fields that require coil splicing, such as pipeline manufacturing, pressure vessels, and automotive parts.

[0003] A search revealed that Chinese patent CN212885911U discloses a "coil welding fixing fixture," which includes a worktable, rollers, a positioning component, and a pressure roller. Rollers for supporting the coil are installed on both sides of the worktable. A boss for guiding and limiting the coil is provided on the worktable. A positioning component for fixing two coils is installed in the middle of the worktable. A pressure roller for pressing the coil is also inserted into the worktable, near the coil input end. This invention has a simple structure, is easy to operate, and can position and fix two products to be welded, facilitating subsequent welding and grinding. It is easier and safer for operators, and the quality is relatively stable. However, it still has the following drawbacks: (1) Most of the coiled material is made of metal, which is heavy and has sharp edges. Manual feeding has obvious shortcomings. Furthermore, the edges of the coiled material may have burrs or sharp angles, which can easily cause cuts when manually adjusted. If the coiled material slips during transportation, it may also cause accidents such as being crushed.

[0004] (2) The weld of the coil material that has just been welded is in a high temperature state and the weld metal has not been completely cooled and solidified. Its mechanical properties are weak. If the operation is not proper when manually removing it, it is easy to cause the weld to deform or misalign. Therefore, a straight seam welding fixture for coil material products is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problem that most of the existing coil materials are made of metal, which are heavy and have sharp edges. Manual feeding has obvious shortcomings, and the edges of the coil materials may have burrs or sharp angles, which can easily cause cuts when manually adjusted. If the coil materials slip during transportation, it may also cause accidents such as being crushed.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a straight seam welding fixture for coil products, including a base plate, on the surface of which a fixed end of a cylinder is fixedly mounted, and on the output end of the cylinder is a sliding plate fixedly mounted. A connecting frame is fixedly mounted on the top of the sliding plate, and on the top of the connecting frame is a fixed end of a right cylinder. A right lower pressure block is fixedly mounted on the output end of the right cylinder. A right positioning block and a left positioning block are fixedly mounted on the surface of the base plate. A left lower pressure mechanism is provided on the surface of the base plate. The fixture also includes a feeding mechanism, which includes a fixed frame. The fixing frame is fixedly installed on the front side of the base plate. A placement frame is fixedly installed on the inner wall of the fixing frame. A reciprocating screw is rotatably installed on the inner wall of the fixing frame. A piston frame is threaded on the circumferential surface of the reciprocating screw. Several vacuum nozzles are provided on the surface of the piston frame near the placement frame. By placing the roll material in the placement frame, the roll material is physically shaped into a U-shape. Then, the two sides of the roll material are vacuum-adsorbed by the multiple vacuum nozzles. Then, the reciprocating screw is rotated by the motor, causing the piston frame to move until it moves to the surface of the right positioning block and the left positioning block.

[0007] As a preferred technical solution of this utility model, the fixed end of the left lower pressing mechanism is fixed to the surface of the base plate and includes related components of the right lower pressing mechanism. The right lower pressing block is moved by the output end of the right cylinder, and the left lower pressing mechanism does the same, so that both sides of the coil are pressed at the same time.

[0008] As a preferred technical solution of this utility model, a cylinder two is fixedly installed on the surface of the base plate, and a tension rod is fixedly installed on one side of the output end of the cylinder two. The other side of the tension rod is slidably installed on the inner wall of the base plate. A backing plate is fixedly installed on the surface of the tension rod. The reciprocating screw two is rotated by a motor, so that the L-shaped sliding knobs on the left and right sides move towards each other, so that both sides of the coil material are moved to contact the backing plate at the same time.

[0009] As a preferred technical solution of this utility model, the number of the backing plates is set to three, and they are arranged in a linear array along the tension rod.

[0010] As a preferred technical solution of this utility model, a reciprocating screw two is rotatably mounted on the surface of the connecting frame, and an L-shaped slide button is threaded on the circumferential surface of the reciprocating screw two. The fixed end of the hydraulic rod is fixedly mounted on the surface of the L-shaped slide button, and a clamping plate is fixedly mounted on the output end of the hydraulic rod. The coiled material contacts the inner wall of the L-shaped slide button, and then the output end of the hydraulic cylinder extends to drive the clamping plate to clamp the outer wall of the coiled material. The clamping is performed simultaneously by the clamping plates in four directions.

[0011] As a preferred technical solution of this utility model, the number of the reciprocating lead screw, L-shaped slide button, hydraulic rod and clamping plate is set to four, in pairs, and symmetrical to each other along the vertical central axis of the right positioning block.

[0012] As a preferred technical solution of this utility model, the surface of the fixing frame is provided with a feeding mechanism, which includes a reciprocating lead screw three. The inner wall of the base plate is fixedly installed with the fixed end of a servo motor. The circumferential surface of the reciprocating lead screw three is threaded with a top plate. The output end of the servo motor drives the first belt to rotate the left reciprocating lead screw three. The rotation of the left reciprocating lead screw three drives the second belt to rotate the right reciprocating lead screw three, so that the two reciprocating lead screw three rotate synchronously, causing the top plates on both sides to move forward, thereby automatically pushing out the welded coil.

[0013] As a preferred technical solution of this utility model, the number of the reciprocating lead screw three and the top plate is set to two, and they are symmetrical to each other along the vertical central axis of the fixed frame. The left reciprocating lead screw three is connected to the output end of the servo motor through belt No. 1, and the right reciprocating lead screw three is connected to the left reciprocating lead screw three through belt No. 2.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The automatic feeding mechanism places the roll material into a U-shape by placing it in the placement rack. Roll products are often heavy and have sharp edges. Manual feeding requires bending over to move and align the roll, which is not only labor-intensive but also prone to accidents such as crushing and cutting due to improper operation. The automatic feeding mechanism can transfer the roll material by vacuum suction nozzle. After the operator places the roll material in the placement rack and the automatic forming step is completed, the subsequent automatic welding of the roll material is carried out, which further reduces the risk of work injury and improves the working environment. 2. The feeding mechanism automatically pushes out the welded coil. The weld is not completely cooled after welding, and manual contact may cause burns or deformation of the weld due to external force. The top plate driven by the reciprocating screws on both sides solves the above problems through synchronization and force control. The moving speed and distance of the top plates on both sides are completely consistent, ensuring that the coil moves out smoothly in a straight line and avoids tilting and collision.

[0021] like Figures 1-5As shown, this embodiment proposes a straight seam welding fixture for coil products, including a base plate 1. A fixed end of a cylinder 2 is fixedly mounted on the surface of the base plate 1. A sliding plate 3 is fixedly mounted on the output end of the cylinder 2. A connecting frame 4 is fixedly mounted on the top of the sliding plate 3. A fixed end of a right cylinder 5 is fixedly mounted on the top of the connecting frame 4. A right lower pressure block 6 is fixedly mounted on the output end of the right cylinder 5. A right positioning block 7 and a left positioning block 8 are fixedly mounted on the surface of the base plate 1. A left lower pressure mechanism 9 is provided on the surface of the base plate 1. The fixture also includes a feeding mechanism 12. The material handling mechanism 12 includes a fixed frame 1200, which is fixedly installed on the front side of the base plate 1. A placement frame 1201 is fixedly installed on the inner wall of the fixed frame 1200. A reciprocating screw 1202 is rotatably installed on the inner wall of the fixed frame 1200. A piston frame 1203 is threaded on the circumferential surface of the reciprocating screw 1202. Several vacuum nozzles 1204 are provided on the surface of the piston frame 1203 near the placement frame 1201, so that the roll material is physically arranged to be U-shaped. Then, the two sides of the roll material are vacuum-adsorbed by the multiple vacuum nozzles 1204.

[0022] like Figures 1-4 As shown, in a preferred embodiment, based on the above method, the fixed end of the left lower pressing mechanism 9 is further configured to be fixed to the surface of the base plate 1, and includes related components of the right lower pressing mechanism.

[0023] like Figures 1-4 As shown, in a preferred embodiment, based on the above method, a second cylinder 10 is fixedly installed on the surface of the base plate 1, and a tension rod 11 is fixedly installed on one side of the output end of the second cylinder 10. The other side of the tension rod 11 is slidably installed on the inner wall of the base plate 1, and a backing plate 110 is fixedly installed on the surface of the tension rod 11, so that both sides of the coil are moved simultaneously to contact the backing plate 110.

[0024] like Figure 4 As shown, in a preferred embodiment, based on the above method, the number of backing plates 110 is further set to three, and they are arranged in a linear array along the tension rod 11.

[0025] like Figure 7 As shown, in a preferred embodiment, based on the above method, a reciprocating screw 1205 is rotatably mounted on the surface of the connecting frame 4. An L-shaped slide button 1206 is threaded on the circumferential surface of the reciprocating screw 1205. The fixed end of a hydraulic rod 1207 is fixedly mounted on the surface of the L-shaped slide button 1206. A clamping plate 1208 is fixedly mounted on the output end of the hydraulic rod 1207. The coil is fixed by clamping simultaneously by the clamping plates 1208 in four directions. At this time, the clamping of the vacuum nozzle 1204 can be released. The coil continues to be U-shaped and clamped by the clamping plates 1208 in four directions.

[0026] like Figure 6 and Figure 7 As shown, in a preferred embodiment, based on the above method, the number of reciprocating lead screw 1205, L-shaped slide button 1206, hydraulic rod 1207 and clamping plate 1208 is further set to four, in pairs, and symmetrical to each other along the vertical central axis of the right positioning block 7.

[0027] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the surface of the fixing frame 1200 is further provided with a material discharge mechanism 13. The material discharge mechanism 13 includes a reciprocating screw 1300. The fixed end of the servo motor 1301 is fixedly installed on the inner wall of the base plate 1. The circumferential surface of the reciprocating screw 1300 is threaded with a top plate 1302, so that the welded coil is automatically pushed out. The weld that has just been welded has not been completely cooled. Manual contact may cause burns, or the weld may be deformed due to external force.

[0028] like Figure 5 and Figure 6 As shown, there are two reciprocating screws 1300 and top plates 1302, which are symmetrical about each other along the vertical central axis of the fixed frame 1200. The left reciprocating screw 1300 is connected to the output end of the servo motor 1301 via belt No. 1, and the right reciprocating screw 1300 is connected to the left reciprocating screw 1300 via belt No. 2. The moving speed and distance of the top plates 1302 on both sides are completely consistent, ensuring that the coil moves out smoothly along a straight line and avoiding skewed collisions.

[0029] Specifically, when using the straight seam welding fixture for this coil product: the coil is placed in the placement rack 1201, which physically shapes the coil into a U-shape. Multiple vacuum nozzles 1204 then vacuum-adhere both sides of the coil. The reciprocating screw 1202 is then rotated by a motor, causing the piston frame 1203 to move until it reaches the surfaces of the right positioning block 7 and the left positioning block 8. At this point, the coil contacts the inner wall of the L-shaped sliding button 1206. The output end of the hydraulic rod 1207 then extends... The extension clamping plate 1208 clamps the outer wall of the coil material. The coil material is fixed by the simultaneous clamping of the clamping plates 1208 in four directions. At this point, the clamping of the vacuum nozzle 1204 can be released. The coil material continues to be U-shaped and clamped by the clamping plates 1208 in four directions. The reciprocating screw 1205 is then rotated by the motor, causing the L-shaped sliding buttons 1206 on both sides to move towards each other, moving both sides of the coil material simultaneously until they contact the backing plate 110. At this point, the coil material also contacts the right positioning block 7 and the left positioning block 8. The surface contacts the coil material. At this time, the output end of the right cylinder 5 drives the right lower pressure block 6 to move, and the left lower pressure mechanism 9 does the same, so that both sides of the coil material are pressed at the same time. Then, the output end of the second cylinder 10 retracts and drives the tension rod 11 to move. The movement of the tension rod 11 causes the backing plate 110 to move downward, so that the backing plate 110 is below the right positioning block 7 and the left positioning block 8. Then, the output end of the first cylinder 2 extends and drives the sliding plate 3 to move. The movement of the sliding plate 3 drives the connecting frame 4 to move, so that the left and right sides of the coil material are joined together. Then the welding system starts welding. Coil material products are often heavy and have sharp edges. When manually loading the material, it is necessary to bend over to carry and align them. This not only results in high labor intensity, but also easily leads to safety accidents such as crushing and cutting due to improper operation. The automatic loading mechanism 12 can use the vacuum suction nozzle 1204 to complete the transfer of the coil material. After the operator places the coil material on the placement frame 1201 for automatic forming, the subsequent automatic coil material welding is carried out, further reducing the risk of work-related injuries and improving the working environment. When the coil is conveyed to the surfaces of the right positioning block 7 and the left positioning block 8, the outer wall of the coil also contacts the top plate 1302. After welding, the output end of the servo motor 1301 drives the first belt to rotate the left reciprocating screw 3 1300. The rotation of the left reciprocating screw 3 1300 drives the second belt to rotate the right reciprocating screw 3 1300. The two reciprocating screws 3 1300 rotate synchronously, causing the top plates 1302 on both sides to move forward, thus automatically pushing out the welded coil. The weld is not completely cooled after welding, and manual contact may cause burns or deformation of the weld due to external force. The top plates 1302 driven by the two reciprocating screws 3 1300 solve the above problems through synchronization and force controllability. The moving speed and distance of the two top plates 1302 are completely consistent, ensuring that the coil moves out smoothly in a straight line and avoiding skewed collisions.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
