Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a welding device for automotive seat slide rail screws. Background Technology

[0002] The mounting bolts for car seats need to be welded and fixed in the grooves of the car seat slide rails. Since the installation position of the bolts is fixed, this process is usually done manually after the bolts are installed in place, which is inefficient.

[0003] Existing technology uses automated equipment to first insert bolt 9 into the groove of the car seat slide rail 8, such as... Figure 1 As shown, a robotic arm is then used to move the car seat slide rail to an automatic welding machine for welding. For example, Chinese utility model patent CN222971210U discloses an automatic feeding and discharging device for projection welding bolts on the inner rail of a car seat slide rail. This device places the bolts into the corresponding positions on the inner rail of the slide rail through a feeding device. The robot picks up the inner rail of the slide rail with the bolts and transfers it to the welding machine. After the welding machine welds the bolts onto the inner rail of the slide rail, the robot picks up the inner rail of the slide rail with the welded bolts and transfers it to the discharging device. The discharging device transfers the inner rail of the slide rail with the welded bolts to a designated location, achieving automated feeding, welding, and discharging. However, during the process of the robot picking up the inner rail of the slide rail and transferring it to the welding machine position, the bolts cannot be fixed in position. During the transfer process, the position of the bolts will shift, resulting in the bolt heads being crooked, inaccurate welding, and low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for automotive seat slide rail screws, which solves the above-mentioned technical problems, automatically corrects bolt misalignment, and ensures accurate bolt welding position and direction.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a welding device for automotive seat slide rail screws, comprising a conveying component, an automatic reset component, and a welding machine. The conveying component is provided with a clamping component for clamping the automotive seat slide rail. The conveying component is used to sequentially convey the automotive seat slide rail to the area below the automatic reset component and the welding machine. The automatic reset component includes a fixing block, on which an mounting block is fixed. Two slide rods are slidably connected within the mounting block. One end of each slide rod is detachably connected to a reset block, and the other end is provided with a locking component for locking the slide rod. A downward inclined surface is provided below the reset block, and a vertical surface extends downward along the bottom of the inclined surface. The two vertical surfaces are arranged opposite each other, and a bolt passage space is formed between them.

[0006] By adopting the above technical solution, a conveying component moves the car seat slide rail containing bolts in the groove sequentially to the automatic reset component for reset. The welding machine then welds the bolts to the car seat slide rail. During the conveying process, the clamping component always holds the car seat slide rail to ensure stability. A sliding rod aligns the bolt passage space with the bolt head. A locking component then locks the sliding rod in place. When the conveying component moves the car seat slide rail to the bolt passage space, two reset blocks are located in the groove of the slide rail and are offset to the left and right on either side of the bolt. The bolt direction is corrected sequentially from both sides. The inclined surface presses down on the bolt and prevents vertical movement during adjustment, thus limiting the bolt downwards. This automatically resets the bolt during the conveying process, facilitating direct welding without manual adjustment, improving welding accuracy and efficiency.

[0007] A further feature of this invention is that: a tightening screw is provided on the top of the reset block, and an internal thread is provided at one end of the slide rod near the conveying assembly; the tightening screw passes through the threaded connection of the reset block and the slide rod.

[0008] By adopting the above technical solution, the reset block and the slide bar are detachably connected by a tightening screw, which facilitates the replacement and maintenance of the reset block.

[0009] The present invention is further configured as follows: the locking assembly includes a clamping member that is fixedly connected to the mounting block. The clamping member includes a fixed cylinder and several spring pieces. Each spring piece includes a connecting piece. One end of the connecting piece is fixedly connected to the fixed cylinder, and the other end is provided with a conical surface. There is a gap between two adjacent spring pieces. The several conical surfaces form a frustum shape. The clamping member is externally threaded with a tightening sleeve. The inner part of the tightening sleeve at the end away from the mounting block is provided with an inwardly protruding inclined surface. The inwardly protruding inclined surface is connected to the conical surface. When the tightening sleeve moves to the left, it drives the several conical surfaces to move closer to each other. The sliding rod slides through the middle of the fixed cylinder and the spring pieces.

[0010] By adopting the above technical solution, a rotating tightening sleeve is set to achieve the left and right movement of the tightening sleeve. When the tightening sleeve moves to the right, the conical surface and the inner convex inclined surface move away from each other, releasing the limit on the conical surface. Several conical surfaces move away from each other, thereby releasing the locking of the sliding rod. At this time, the two sliding rods can be slidably adjusted to adjust the misalignment distance of the reset block. It can adapt to the automatic reset of bolts of various specifications and has wide applicability. When the tightening sleeve moves to the left, the conical surface and the inner convex inclined surface move closer to each other. The inner convex inclined surface gradually presses against the conical surface, making the conical surfaces move closer to each other until several spring pieces lock the sliding rod, thereby achieving the locking and fixing of the sliding rod. The structure is simple and the locking and loosening of the sliding rod is quick and convenient, further improving welding efficiency.

[0011] A further feature of this invention is that a base plate is welded to one end of the fixed cylinder near the mounting block, and the base plate and the mounting block are fixedly connected by connecting screws.

[0012] By adopting the above technical solution, the base plate is welded to the fixed cylinder, and the chassis is fixed to the mounting block by bolts, thereby achieving a fixed connection between the fixed cylinder and the mounting block.

[0013] A further feature of this invention is that the two reset blocks are staggered left and right to adjust the direction of the bolts.

[0014] A further feature of this invention is that the conveying assembly includes a worktable, a U-shaped seat is provided on the worktable, a lead screw is rotatably connected to the U-shaped seat, a sliding block is threadedly connected to the lead screw, the sliding block is slidably connected to the U-shaped seat, a base plate is fixedly provided on the sliding block, and a U-shaped base for placing the car seat slide rail is fixedly provided on the base plate.

[0015] By adopting the above technical solution, the car seat slide rail with bolts is placed on the U-shaped base. The screw is rotated to drive the sliding block to slide along the inside of the U-shaped base, thereby driving the base plate, the U-shaped base and the car seat slide rail to move left and right, which plays the role of automatically conveying the car seat slide rail and further ensuring welding efficiency.

[0016] A further feature of this invention is that the clamping assembly includes pneumatic grippers located at opposite ends of the U-shaped base for clamping both sides of the car seat slide rail, and at least two pneumatic grippers are provided.

[0017] By adopting the above technical solution, the car seat slide rail with bolts is placed on the U-shaped base and the electric grippers at both ends are activated to clamp the two sides of the car seat slide rail respectively, preventing the car seat slide rail from shaking during transportation and further ensuring the accuracy of welding.

[0018] A further feature of this invention is that it also includes a drive motor, which is used to drive the lead screw to rotate.

[0019] By adopting the above technical solution, a drive motor is set up to drive the lead screw to rotate in both directions, thereby continuously conveying the car seat slide rail, resulting in high automation efficiency.

[0020] A further feature of this invention is that the side wall of the conveying assembly is provided with a mounting bracket, and a lifting cylinder is provided on the mounting bracket, with the piston rod of the lifting cylinder fixedly connected to a fixing block.

[0021] By adopting the above technical solution, a lifting cylinder is set to drive the fixed block to rotate, thereby driving the mounting block, slide rod, and reset block to move up and down. This makes it easy to adjust the depth of the reset block extending into the car seat slide rail, and can be adapted to the processing of various models of car seat slide rails, with wide applicability.

[0022] A further feature of this invention is that the automatic reset component is positioned close to the welding machine.

[0023] The beneficial effects of this utility model are: 1. This utility model uses a conveying assembly to move the car seat slide rail containing bolts in the groove sequentially to the automatic reset assembly for reset. The welding machine then welds the bolts to the car seat slide rail. During the conveying process, the clamping assembly constantly holds the car seat slide rail to ensure stability. A sliding rod allows the bolt's passage space to be matched with the bolt head. Then, a locking assembly locks the sliding rod in place. When the conveying assembly moves the car seat slide rail to the bolt passage space, two reset blocks are located in the groove of the slide rail and are offset to the left and right on either side of the bolt. The bolt's direction is corrected sequentially from both sides. The inclined surface presses down on the bolt and prevents vertical movement during adjustment, thus limiting the bolt's downward movement. This automatically resets the bolt during the conveying process, facilitating direct welding without manual adjustment, improving welding accuracy and efficiency.

[0024] 2. This utility model uses a rotating tightening sleeve to move the tightening sleeve left and right. When the tightening sleeve rotates to the right, the conical surface and the inner convex inclined surface move away from each other, thereby releasing the restriction on the conical surface. As the conical surfaces move away from each other, the locking of the sliding rod is released. At this time, the two sliding rods can be slidably adjusted to adjust the misalignment distance of the reset block. It can adapt to the automatic reset of bolts of various specifications and has wide applicability. When the tightening sleeve moves to the left, the conical surface and the inner convex inclined surface move closer to each other. The inner convex inclined surface gradually presses against the conical surface, causing the conical surfaces to move closer to each other until several spring pieces lock the sliding rod, thereby locking and fixing the sliding rod. The structure is simple and the locking and unlocking of the sliding rod is quick and convenient, further improving welding efficiency. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

Figures 2-5 As shown, the assembly includes a conveying component 1, an automatic reset component 2, and a welding machine 3. The automatic reset component 2 is positioned close to the welding machine 3. The conveying component 1 is equipped with a clamping component 4 for clamping the car seat slide rail 8. The conveying component 1 is used to sequentially convey the car seat slide rail 8 to the area below the automatic reset component 2 and the welding machine 3. The automatic reset component 2 includes a fixing block 21, on which an mounting block 22 is fixed. Two slide rods 23 are slidably connected within the mounting block 22. One end of each slide rod 23 is detachably connected to a reset block 24, and the other end is equipped with a locking component 5 for locking the slide rod 23. A downward inclined surface 240 is provided below the reset block 24, and a vertical surface 241 extends downward along the bottom of the inclined surface 240. The two vertical surfaces 241 are arranged opposite each other, and a space is formed between them for the bolt 9 to pass through. The two reset blocks 24 are staggered left and right to adjust the direction of the bolt 9.

[0034] Specifically, the top of the reset block 24 is provided with a tightening screw 25, and the end of the slide rod 23 near the conveying assembly 1 is provided with an internal thread. The tightening screw 25 passes through the reset block 24 and is threaded to the slide rod 23, so as to realize the detachable connection between the reset block 24 and the slide rod 23.

[0035] Specifically, the locking assembly 5 includes a clamping member 51 that is fixedly connected to the mounting block 22. The clamping member 51 includes a fixed cylinder 510 and several spring pieces 511. Each spring piece 511 includes a connecting piece 5110. One end of the connecting piece 5110 is fixedly connected to the fixed cylinder 510, and the other end is provided with a conical surface 5111. There is a gap between two adjacent spring pieces 511. The several conical surfaces 5111 form a frustum shape. The clamping member 51 is externally threaded with a tightening sleeve 52. The tightening sleeve 52 has an inwardly protruding inclined surface 520 at the end away from the mounting block 22. The inwardly protruding inclined surface 520 is in contact with the conical surface 5111. When the tightening sleeve 52 moves to the left, it drives the several conical surfaces 5111 to move closer to each other. The sliding rod 23 slides through the middle of the fixed cylinder 510 and the spring pieces 511.

[0036] Specifically, a base plate 53 is welded to one end of the fixing cylinder 510 near the mounting block 22. The base plate 53 and the mounting block 22 are fixedly connected by connecting screws 54, thereby achieving a fixed connection between the fixing cylinder 510 and the mounting block 22.

[0037] Specifically, the conveying assembly 1 includes a worktable 11, on which a U-shaped seat 12 and a drive motor 17 are provided. A lead screw 13 is rotatably connected to the U-shaped seat 12, and a sliding block 14 is threadedly connected to the lead screw 13. The sliding block 14 is slidably connected to the U-shaped seat 12, and a base plate 15 is fixedly provided on the sliding block 14. A U-shaped base 16 for placing the car seat slide rail 8 is fixedly provided on the base plate 15. The drive motor 17 is used to drive the lead screw 13 to rotate, thereby realizing the automatic conveying of the workpiece.

[0038] Specifically, the clamping assembly 4 includes pneumatic grippers 41 located at opposite ends of the U-shaped base 16 for clamping both sides of the car seat slide rail 8. At least two pneumatic grippers 41 are provided to ensure the stability of the car seat slide rail 8 with bolts 9 during transport.

[0039] Specifically, the side wall of the conveying component 1 is provided with a mounting bracket 6, and the mounting bracket 6 is provided with a lifting cylinder 7. The piston rod of the lifting cylinder 7 is fixedly connected to the fixing block 21, which is suitable for various types of car seat slide rails 8.

[0040] Its working principle is as follows: First, rotate the tightening sleeve 52 to the right, causing the conical surface 5111 and the inner convex inclined surface 520 to move away from each other, releasing the restriction on the conical surface 5111. As the conical surfaces 5111 move away from each other, the locking of the slide rod 23 is released. At this point, the two slide rods 23 can be slidably adjusted to adjust the misalignment distance of the reset block 24, ensuring that the vertical surfaces 241 of the two reset blocks 24 are opposite each other and the distance matches the shape and size of the bolt head 9. Next, rotate the tightening sleeve 52 to the left, causing the conical surface 5111 and the inner convex inclined surface 520 to move closer together. The inner convex inclined surface 520 gradually presses against the conical surface 5111, causing the conical surfaces 5111 to move closer together until several spring pieces 511 lock the slide rod 23, thus achieving the locking of the slide rod 23. After locking and fixing, adjust the lifting cylinder 7 to drive the fixing block 21 to rotate, thereby driving the mounting block 22, slide rod 23, and reset block 24 to move up and down. Adjust the bottom of the reset block 24 to contact the head of the bolt 9. Finally, place the car seat slide rail 8 with the bolt 9 on the U-shaped base 16. Rotate the screw 13 to drive the slide block 14 to slide along the inside of the U-shaped base 12, thereby driving the base plate 15, U-shaped base 16, and car seat slide rail 8 to automatically pass through two reset blocks 24 once. The reset block 24 resets the bolt 9. When it is transported to the welding machine 3, the transport stops. The welding machine 3 welds the bolt 9 and the reset block 24 together. After the processing is completed, unload the material. The screw 13 rotates in the opposite direction to drive the base plate 15 to reset, and proceed to the processing of the next workpiece.

[0041] In addition, the present invention can reasonably set up dustproof devices and methods for the lead screw 13, such as setting an L-shaped dustproof cover around the lead screw 13, cleaning the lead screw 13 regularly, etc. Since the dustproof methods and devices for the lead screw 13 are common knowledge in the field, the present invention will not explain or elaborate on the dustproof measures and devices for the lead screw 13.
