Description

Technical Field

[0001] This utility model relates to the field of workpiece welding technology, and in particular to a rapid positioning mechanism for workpiece welding. Background Technology

[0002] A workpiece refers to an item formed after various processing techniques during the manufacturing process. Specifically, it can be made of materials such as metal, plastic, paper, and glass, or it can be a component of a machine or equipment. Whether it's large-scale machinery or tiny electronic components, all rely on the processing and manufacturing of workpieces. During the manufacturing process, workpieces play a crucial role in connecting, transmitting, storing, and converting energy, forming the foundation of product quality. In summary, workpieces, as items in the manufacturing process, hold an indispensable position and are of paramount importance in product processing and manufacturing. Welding procedures, industrial processes, are related to factors such as the process and welding method. During operation, the method must be determined based on the material, grade, chemical composition, structural type, and welding performance requirements of the workpiece being welded. Current workpiece welding positioning methods rely on manual positioning, which can easily cause burns to workers and is prone to errors during welding.

[0003] Therefore, it is necessary to design a rapid positioning mechanism for workpiece welding to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

Figures 1-6 As shown, the device includes a fixed rod 1, a base 2, a drive motor 3, a gear 4, a rack 5, a placement rod 6, a calibration rod 7, a connecting block 8, a moving wheel 9, and a first clamping block 10. Fixed rods 1 are welded to both the front and rear sides of the base 2. Two pairs of mounting holes 201 are provided on both the left and right sides of the base 2. The drive motor 3 is installed at the lower part of the base 2. The output shaft of the drive motor 3 is fixedly connected to the gear 4. The gear 4 is rotatably connected to the base 2. Racks 5 are slidably connected to both the front and rear sides of the lower part of the base 2. Both racks 5 mesh with the gear 4. The racks 5 are slidably connected to the fixed rod 1. Placement rods 6 are fixedly connected to the ends of both racks 5 away from the center. Calibration rods 7 are welded to the ends of both placement rods 6 away from the center. Connecting blocks 8 are fixedly connected to the front of the left placement rod 6 and the rear of the right placement rod 6. Moving wheels 9 are rotatably connected to the bottom of the two connecting blocks 8. Moving wheels 9 on the same side are rotatably connected to the fixed rod 1. Four first clamping blocks 10 are fixedly connected to the left and right sides of the two placement rods 6.

[0023] like Figure 1 , Figure 4 and Figure 6 As shown, it also includes a sliding frame 11, a first spring 12, a column 13, a second clamping block 14, and a second spring 15. The top of each of the two placement rods 6 is slidably connected to the sliding frame 11. Two first springs 12 are fixedly connected between the placement rod 6 and the sliding frame 11 on the same side. Eight columns 13 are slidably connected to the left and right sides of the two sliding frames 11. The bottom of each of the sixteen columns 13 is fixedly connected to the second clamping block 14. The first clamping block 10 and the second clamping block 14 correspond to each other, with the corresponding first clamping block 10 located directly below the second clamping block 14. Each of the sixteen second clamping blocks 14 is fixedly connected to the sliding frame 11 with a second spring 15.

[0024] like Figure 4 As shown, it also includes mounting bases 16 and rollers 17. Two mounting bases 16 are fixedly connected to the top of each of the two sliding frames 11, and rollers 17 are rotatably connected to each of the four mounting bases 16.

[0025] like Figure 1 and Figure 3 As shown, it also includes a guide frame 18. Two guide frames 18 are fixedly connected between the middle of the two fixed rods 1. The guide frame 18 on the same side is rotatably connected to the roller 17 on the same side.

[0026] like Figure 1 and Figure 5 As shown, it also includes suction cups 19, air tubes 20 and air pumps 21. Three suction cups 19 are fixedly connected to the top of each of the two placement rods 6. Air tubes 20 are fixedly connected between the bottoms of the three suction cups 19 on the same side. Air pumps 21 are provided at the front of each of the two air tubes 20.

[0027] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes baffles 22, collection frames 23 and material-pushing blocks 24. Baffles 22 are bolted to both the front and rear sides of the base 2, and collection frames 23 are slidably connected to both the left and right sides of the base 2. Material-pushing blocks 24 are fixedly connected to the front of both collection frames 23.

[0028] like Figure 4 As shown, it also includes anti-slip rubber blocks 25, with anti-slip rubber blocks 25 provided on the top of the sixteen first clamping blocks 10 and the bottom of the sixteen second clamping blocks 14.

[0029] When this device is needed to assist in workpiece welding, first fix the device through the mounting holes 201 on the base 2. Then, place the two workpieces on the left and right placement rods 6 respectively. Use the calibration rod 7 to position the workpieces correctly. Then, start the air pump 21 to drive gas from the suction cup 19 into the air pipe 20 and then out through the air pump 21, thereby sucking the workpieces onto the placement rods 6 and fixing them. Then, start the drive motor 3 to drive the gear 4 to rotate clockwise, thereby moving the two racks 5 towards the center end, and moving the left and right placement rods 6 towards the center end. The two moving wheels 9 rotate towards the center end on the fixed rod 1 as the placement rods 6 move, reducing the friction between the placement rods 6 and the fixed rod 1. The friction between rods 1 causes the guide frame 18 to contact the roller 17 as the rod 6 moves. The left roller 17 rotates clockwise and the right roller 17 rotates counterclockwise, causing the sliding frame 11 and the second clamping block 14 to move downwards. The first spring 12 is compressed. When the second clamping block 14 touches the workpiece, the second clamping block 14 and the first clamping block 10 clamp the workpiece. The anti-slip rubber block 25 reduces the friction between the second clamping block 14 and the first clamping block 10 and the workpiece, protecting the workpiece. The second spring 15 is compressed. When the two workpieces contact each other, the drive motor 3 is turned off, and the worker can then weld the two workpieces. The baffle 22 protects the worker from burns. After welding is completed, the air pump 21 is turned off, and the workpiece is no longer sucked on the rod 6.

[0030] The drive motor 3 is started, which drives the gear 4 to rotate counterclockwise, thereby moving the placement rods 6 on the left and right sides away from the center. The left roller 17 rotates counterclockwise and the right roller 17 rotates clockwise. The first spring 12 and the second spring 15 slowly extend and reset. The welded workpiece is no longer clamped and falls onto the base 2. The worker then takes out the welded workpiece for processing. The worker then sweeps the waste generated by welding on the base 2 into the collection frames 23 on the left and right sides using a brush or other means. Then, by pulling the material-pulling block 24 forward, the collection frame 23 is pulled out to process the waste. After processing, the material-pulling block 24 is pushed backward to reset the collection frame 23. If the workpiece still needs to be welded, the above operation can be repeated.
