Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary tooling, in particular to an auxiliary tooling for fixing welding points of parts. Background Art

[0002] In modern industrial production, the welding of parts is a crucial process. As a key step in the welding process, the quality of the weld spot directly affects the performance and reliability of the final welded product. With the continuous advancement of technology and the increasing sophistication of industrial production, the quality and precision of parts welding are becoming increasingly demanding. During the welding process, it is often necessary to position the parts, so auxiliary tooling is needed.

[0003] In the prior art, traditional auxiliary tooling has major defects. For example, when traditional auxiliary work is used to fix parts, it is often necessary to open the welding cover first, clamp it with a clamp, and then close the welding cover to achieve the fixing effect. However, this method is cumbersome every time it is fixed, which seriously affects the efficiency of welding. Therefore, the utility model proposes an auxiliary tooling for fixing the welding points of parts to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose an auxiliary tooling for fixing the welding points of parts.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The two cams are connected by a plurality of levers, each of which is connected to the support frame of the mounting plate, and the two cams are connected by a plurality of levers, each of which is connected to the support frame of the mounting plate.

[0007] Preferably, the rotating mechanism comprises two fixing plates respectively fixedly connected to the side walls at both ends of the welding cover, and the lower ends of the two fixing plates are fixedly connected to racks meshing with gears.

[0008] Preferably, the moving mechanism includes two symmetrically arranged electric push rods fixedly connected to the upper end of the placement plate, and the telescopic ends of the two electric push rods are fixedly connected to the lower end of the fixed plate.

[0009] Preferably, the ends of the two clamping columns are elastically connected to the inner wall of the groove on the same side via a second spring.

[0010] Preferably, the upper end surface of the placement plate is provided with two symmetrically arranged sliding grooves, and sliders are slidably connected in the two sliding grooves, and the upper ends of the two sliders are fixedly connected to positioning columns.

[0011] Preferably, the side walls of the two sliding blocks are elastically connected to the inner wall of the sliding groove on the same side via a first spring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up a moving mechanism and a clamping mechanism, the workpiece is placed on the placement plate. During welding, the telescopic end of the electric push rod is driven to retract, driving the fixed plate and the welding cover to move downward, thereby driving the rack to move downward. The downward movement of the rack drives the gear meshing with it to rotate, driving the double-headed threaded rod to rotate, and driving the moving block threadedly connected to it to move closer to the middle to clamp the parts. After welding is completed, the welding cover moves up and the clamping mechanism loosens its grip on the parts, which can complete automatic clamping and is more efficient.

[0014] 2. By setting the slide, slider and positioning column, when placing the parts, first open the positioning columns on both sides to compress the first spring, and then place the parts on the upper end of the placement plate. After the placement is completed, the slider is reset under the action of the first spring, so that the positioning columns on both sides are reset, so that the parts can be quickly positioned and ensure that they are more accurately positioned when fixed.

Under the action of the positioning column 12, the components can be quickly positioned, thereby improving the accuracy of the position during fixation.

[0024] A clamping mechanism for clamping parts is provided inside the through groove 3. The clamping mechanism includes two symmetrically arranged moving blocks 16 that are slidably connected to the through groove 3. A groove 7 is provided at the opposite ends of the two moving blocks 16. A clamping column 9 is slidably connected to the two grooves 7. The ends of the two clamping columns 9 are elastically connected to the inner walls of the groove 7 on the same side by a second spring 17. When clamping, the clamping column 9 first contacts the surface of the component. When the welding cover 2 continues to move downward, the clamping column 9 moves into the groove 7 under extrusion. A double-headed threaded rod 11 is connected to the inner walls of the two ends of the through groove 3 by rotation. The double-headed threaded rod 11 passes through the two moving blocks 16 and is threadedly connected to them. Gears 10 are fixedly sleeved on the double-headed threaded rods 11 located in the two placement grooves 8.

[0025] A welding cover 2 is provided above the placement plate 1, and a rotating mechanism for rotating the double-headed threaded rod 11 is provided on the side walls at both ends of the welding cover 2. The rotating mechanism includes two fixed plates 6 respectively fixedly connected to the side walls at both ends of the welding cover 2, and the lower ends of the two fixed plates 6 are fixedly connected to a rack 4 meshing with the gear 10.

[0026] The upper end of the placement plate 1 is provided with a moving mechanism for moving the welding cover 2. The moving mechanism includes two symmetrically arranged electric push rods 5 fixedly connected to the upper end of the placement plate 1. The telescopic ends of the two electric push rods 5 are fixedly connected to the lower end of the fixed plate 6.

[0027] When the present invention is used, when placing parts, first stretch out the positioning columns 12 on both sides to compress the first spring 14, and then place the parts on the upper end of the placement plate 1. After placement is completed, the slider 15 is reset under the action of the first spring 14, so that the positioning columns 12 on both sides are reset, so that the parts can be quickly positioned to ensure that the position is more accurate when fixed. The workpiece is placed on the placement plate 1. During welding, the telescopic end of the electric push rod 5 is driven to retract, driving the fixed plate 6 and the welding cover 2 to move downward, thereby driving the rack 4 to move downward. The downward movement of the rack 4 drives the gear 10 meshing with it to rotate, driving the double-headed threaded rod 11 to rotate, and driving the moving block 16 threadedly connected to it to move closer to the middle. The moving blocks 16 on both sides drive the clamping columns 9 on both sides to move closer to the middle to clamp the parts. After welding is completed, the welding cover 2 moves up, and the clamping mechanism relaxes the clamping of the parts, which can complete automatic clamping with higher efficiency.
