Detailed ways

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

Example 1:

Please refer to Figures 1 to 3, an adjustable welding fixture includes:

Workbench 1, an L-shaped bracket 11 is fixedly installed on one side of the top of the workbench 1, and a welding machine 12 is provided on the top of the L-shaped bracket 11 close to the side of the workbench 1;

Adjustment component 2. The adjustment component 2 is arranged on one side of the L-shaped bracket 11. The adjustment component 2 includes an adjustment frame 21 and two clamping plates 210 that are movably installed inside the adjustment frame 21. Both clamping plates 210 are movably installed on one side. There is a buffer plate 211. A rotating shaft 22 is movably installed on the side of the L-shaped bracket 11 close to the adjusting frame 21 through a bearing. The end of the rotating shaft 22 away from the L-shaped bracket 11 is fixedly connected to the side of the adjusting frame 21. A gear 23 is fixedly installed on one side of the rotating shaft 22. A rack 26 is meshed and connected to one side of the gear 23 .

Specifically, a cylinder 13 is fixedly installed on one side of the top of the workbench 1, a placement plate 14 is fixedly installed on the output end of the cylinder 13, and a rotating shaft 22 is movably installed on the side of the L-shaped bracket 11 close to the placing plate 14 through a bearing, and the rotating shaft 22 is away from the L-shaped bracket. 11 is fixedly connected to the adjusting frame 21 on one side, a gear 23 is fixedly installed on the outside of the rotating shaft 22, an electric telescopic rod 24 is fixedly installed on the side of the L-shaped bracket 11 close to the rotating shaft 22, and an adjusting block 25 is fixedly connected to the output end of the electric telescopic rod 24. A number of racks 26 are fixedly installed on the side of the block 25 close to the gear 23, and the racks 26 mesh with the gear 23.

It can be seen from the above that the cylinder 13 can push the placing plate 14 to lift, and then drive the workpiece to be welded to lift. During the process of welding the workpiece, the placing plate 14 can be placed directly under the workpiece to provide a certain support force, and the workpiece needs to be turned over. When the workpiece is turned over, it can be far away from the workpiece to provide turning space for the workpiece to be turned over. The rotating shaft 22 can drive the adjusting frame 21 to turn over, and then the clamping plate 210 inside the adjusting frame 21 can synchronously drive the workpiece to turn over. During specific use, it is pushed by the electric telescopic rod 24 The adjusting block 25 moves, and then drives the gear 23 to rotate through the rack 26 on one side of the adjusting block 25, thereby driving the adjusting frame 21 to perform a flipping action along the axis of the rotating shaft 22. At this time, the workpiece clamped by the clamping plate 210 will be synchronized Flip to complete the flipping.

Example 2:

Please refer to Figure 1 and Figure 4. Two threaded blocks 27 are movably installed inside the adjusting frame 21. The two threaded blocks 27 are both slidingly attached to the inner wall of the adjusting frame 21. The two threaded blocks 27 are screwed together inside. A threaded rod 28 is installed. Both ends of the threaded rod 28 are movably mounted on the inner wall of the adjusting frame 21 through bearings. The internal threads of the two threaded blocks 27 are opposite.

Specifically, a motor 29 is installed on the side of the outside of the adjusting frame 21 close to the threaded rod 28 through a fixed seat. The output end of the motor 29 is connected to the shaft transmission of the threaded rod 28 through a coupling. The two threaded blocks 27 are both on the side away from the adjusting frame 21. A clamping plate 210 is fixedly installed, and a buffer plate 211 is movably installed on the opposite sides of the two clamping plates 210. Two limiting rods 212 are movably installed through openings on the side of the clamping plate 210 close to the buffer plate 211. One end of the limit rod 212 close to the buffer plate 211 is fixedly connected to the buffer plate 211. Two springs 213 are connected between the buffer plate 211 and the clamping plate 210. The two springs 213 are located outside the limit rod 212. The placement plate 14 and Rubber pads 214 are provided on both sides of the buffer plate 211 .

It can be seen from the above that arranging two threaded blocks 27 with opposite internal threads can realize that when the threaded rod 28 is rotated under the drive of the motor 29, the two threaded blocks 27 will move towards or oppositely inside the adjusting frame 21, thereby driving The two clamping plates 210 approach or move away from each other to achieve the clamping effect. The buffer plate 211 can buffer the clamped workpiece. When the workpiece first contacts the buffer plate 211, the spring 213 will be compressed. This achieves the purpose of buffering and prevents the clamping plate 210 from being too strong to cause damage to the workpiece. At the same time, under the elastic force of the spring 213, the clamping effect is more stable. A rubber pad 214 can be provided on one side of the placement plate 14 and the buffer plate 211. The friction between the rubber pad 214 and the workpiece is increased, and the welding process is more stable. At the same time, the rubber pad 214 itself has a certain degree of flexibility and can also protect the surface of the workpiece to avoid damage to the surface of the workpiece caused by hard contact.
