Description

Technical Field

[0001] This utility model relates to the field of metal welding technology, specifically to an auxiliary fixture for metal welding that is easy to position. Background Technology

[0002] During the welding of the metal frame, the four metal pipes need to be placed in their respective positions and fixed by manual labor. After being pressed and fixed, the fixed positions need to be tapped by manual labor with a rubber hammer to prevent the workpiece from arching during the pressing process. Since each of the four pipes with different angles needs to be fixed manually and a rubber hammer needs to be used, each step requires a lot of manual operation, resulting in low overall efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary fixture for metal welding that is easy to position, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary clamp for metal welding that facilitates positioning, comprising:

[0005] Support platform;

[0006] The clamping part is located at one end of the top of the support platform. The clamping part includes two corner limiting blocks and two side limiting blocks disposed at the ends opposite to the corner limiting blocks. A U-shaped frame is provided between the side limiting blocks and the corner limiting blocks.

[0007] A fixed cylinder is placed on one side of the support platform. The output end of the fixed cylinder is fixedly connected to a limit block for fixing the workpiece joint from the top.

[0008] The loading section is located on top of the support platform. The loading section includes an end limiting groove for limiting the workpiece. A pusher plate is provided at the bottom of the end limiting groove. A drive unit is provided at the bottom of the pusher plate for driving the pusher plate to move up and down and laterally. A support groove plate is fixedly connected to the top of the support platform and below the end limiting groove for supporting the workpiece and facilitating the reset of the pusher plate.

[0009] Preferably, the fixed cylinder is fixedly connected to the corresponding corner limiting block and side limiting block, the limiting pressure block has an L-shaped structure, the end of the limiting pressure block has an angled structure, the top of the corner limiting block and the side limiting block are both fixedly connected to the limiting sleeve, and the limiting pressure block and the limiting sleeve are slidably connected.

[0010] Preferably, a fixed top rod is fixedly connected to the middle of the limiting pressure block for pressing and fixing the workpiece, and the middle of the corner limiting block and the side limiting block are provided with through holes for the fixed top rod to slide.

[0011] Preferably, the U-shaped frame is fixed to the top of the support platform, and the middle part of the U-shaped frame corresponds to the position of the fixed top rod.

[0012] Preferably, a clamping seat is fixedly connected to the bottom of the end limiting groove, the clamping seat is clamped on the side of the support platform, and a bolt is threaded to the bottom of the clamping seat.

[0013] Preferably, the bottom of the end limiting groove is provided with a pushing notch, and the distance between the pushing notch and the support groove plate is greater than the height of a workpiece and less than the height of a workpiece.

[0014] Preferably, the drive unit includes a linear module fixed to the bottom of the support platform. A sliding channel is provided in the middle of the support platform corresponding to the position of the linear module. A fixed seat is slidably connected inside the sliding channel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting multiple limiting structures such as corner limiting blocks, side limiting blocks, end limiting grooves, and U-shaped frames, the rectangular tube is accurately positioned in different directions and positions, ensuring that the tube can be accurately placed in the designated position before welding. The fixing cylinder drives the L-shaped limiting pressure block to move, and the limiting pressure block passes through the middle of the limiting sleeve, driving the fixing top rod to squeeze and fix the rectangular tube from one end. At the same time, the limiting pressure block slides to the intersection of two tubes and presses and fixes the tube inside the corner limiting block, preventing the workpiece from rising during processing. The lifting mechanism ensures the flatness of the workpiece after welding, improving welding quality. Equipped with a feeding unit, the pusher plate is driven by a drive unit to achieve automatic feeding. The pusher plate can push the pipes located at the bottom of the support groove forward to a designated position. During the pushing process, the pusher notch limits the second layer of pipes at the bottom, achieving orderly feeding, shortening manual feeding time, and improving production efficiency. After completing the pushing action, the pusher plate can automatically reset via a dual-axis cylinder, with the reset height corresponding to the middle of the support groove, facilitating the forward pushing of the pipes again and ensuring the continuity and stability of the feeding process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 , 2As shown in 3, 4, 5, 6, and 9, this utility model provides a technical solution: an auxiliary fixture for metal welding that is easy to position, comprising: a support platform 1; a clamping part placed at one end of the top of the support platform 1, the clamping part including two corner limiting blocks 2 and two side limiting blocks 7 disposed away from one end of the corner limiting blocks 2, a U-shaped frame 6 disposed between the side limiting blocks 7 and the corner limiting blocks 2, a fixing cylinder 3 disposed on one side of the support platform 1, the output end of the fixing cylinder 3 being fixedly connected to a limiting pressure block 4 for fixing the workpiece joint from the top; a feeding part placed at the top of the support platform 1, the feeding part including an end limiting groove 9 for limiting the workpiece, a pusher plate 12 disposed at the bottom of the end limiting groove 9, a driving part disposed at the bottom of the pusher plate 12 for driving the pusher plate 12 to rise and fall and move laterally, a support groove plate 10 fixedly connected at the top of the support platform 1 and below the end limiting groove 9 for supporting the workpiece and facilitating the reset of the pusher plate 12.

[0028] It should be noted that in this embodiment, the two corner limiting blocks 2 are fixed to the ends of the support platform 1, and the side limiting blocks 7 are fixed to the middle of the support platform 1 by bolts. The feeding part pushes the rectangular tube from the bottom of the end limiting groove 9, so that it slides into the corner limiting block 2 through the top of the side limiting block 7. Then, the two horizontal rectangular tubes are placed in the U-shaped frame 6 by hand to form a rectangular structure. The fixed cylinder 3 drives the limiting pressure block 4 to move forward. The limiting pressure block 4 squeezes and fixes the tube. In addition, the top of the limiting pressure block 4 presses and fixes the tube at the connection point, so as to facilitate the automatic welding gun to weld from the inner corner of the rectangle.

[0029] In one embodiment, the fixed cylinder 3 is fixedly connected to the corresponding corner limiting block 2 and side limiting block 7. The limiting pressure block 4 has an L-shaped structure and the end of the limiting pressure block 4 has an angled structure. The top of both the corner limiting block 2 and the side limiting block 7 is fixedly connected to the limiting sleeve 5. The limiting pressure block 4 and the limiting sleeve 5 are slidably connected. The middle of the limiting pressure block 4 is fixedly connected to a fixed top rod 8 for pressing and fixing the workpiece. The middle of both the corner limiting block 2 and the side limiting block 7 is provided with a through hole for the fixed top rod 8 to slide.

[0030] It should be noted that in this embodiment, when the rectangular tube is as follows... Figure 2 After placement, the fixed cylinder 3 drives the limiting pressure block 4 to move forward. The limiting pressure block 4 passes through the middle of the limiting sleeve 5. The limiting pressure block 4 drives the fixed top rod 8 to press and fix the rectangular tube from one end. The limiting pressure block 4 slides to the intersection of the two tubes. The limiting pressure block 4 presses and fixes the tube inside the corner limiting block 2 to prevent the workpiece from tilting upward during processing and affecting the flatness of the workpiece after welding.

[0031] In one embodiment, the U-shaped frame 6 is fixed to the top of the support platform 1, and the middle part of the U-shaped frame 6 corresponds to the position of the fixed top rod 8.

[0032] It should be noted that in this embodiment, the U-shaped frame 6 is used to limit and fix the workpiece in the horizontal direction, so that the workpiece can slide in the U-shaped frame 6 and cooperate with the end fitting.

[0033] In one embodiment, a clamping seat 17 is fixedly connected to the bottom of the end limiting groove 9. The clamping seat 17 is clamped on the side of the support platform 1. A bolt is threaded to the bottom of the clamping seat 17. A push-out notch 13 is opened at the bottom of the end limiting groove 9. The distance between the push-out notch 13 and the support groove plate 10 is greater than the height of a workpiece and less than the height of a workpiece.

[0034] It should be noted that in this embodiment, when the pusher plate 12 moves forward at the top of the support groove plate 10, the pusher notch 13 limits the pipe located in the second layer at the bottom. The pusher plate 12 can push the pipe located at the bottom forward, thereby pushing the pipe to the top of the corner limiting block 2 and the side limiting block 7, so as to realize the automatic push and feeding of the pipe.

[0035] In one embodiment, the drive unit includes a linear module 11 fixedly attached to the bottom of the support platform 1. A sliding channel 18 is provided in the middle of the support platform 1 corresponding to the position of the linear module 11. A fixed seat 14 is slidably connected inside the sliding channel 18. The bottom of the fixed seat 14 is fixedly connected to the movable slide of the linear module 11. A fixed plate 16 is fixedly connected to the top of the fixed seat 14. The fixed plate 16 is slidably connected to the pusher plate 12. A dual-axis cylinder 15 for driving the pusher plate 12 to rise and fall is fixedly connected inside the fixed seat 14.

[0036] It should be noted that, in this embodiment, during the material feeding process, the dual-axis cylinder 15 drives the pusher plate 12 to rise, placing the pusher plate 12 on top of the support groove plate 10. The linear module 11 drives the pusher plate 12 forward through the fixed seat 14 and the fixed plate 16, thereby pushing the pipe forward. When the pipe reaches the designated position, the pusher plate 12 separates from the support groove plate 10. Under the action of the limit switch, the dual-axis cylinder 15 drives the pusher plate 12 to reset, so that the height of the pusher plate 12 corresponds to the middle of the support groove plate 10. The dual-axis cylinder 15 drives the pusher plate 12 to reset from the groove in the middle of the support groove plate 10 to the end of the support groove plate 10. The pipe falls back onto the top of the support groove plate 10 under gravity, making it convenient to push the pipe forward again. This reduces the manual feeding time from four pipes to two, shortening the manual feeding time and improving production efficiency.
