Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to an automatic correction tool for welding fork processing. Background Art

[0002] The welding fork is a transmission shaft forging, which is generally produced by forging technology and has a U-shape. As an important transmission component in the automobile, it not only has strict requirements on material and strength, but also has high requirements on its size parameters.

[0003] In an automatic correction tooling for welding forks disclosed in my country's utility model patent CN220825912U, an electric push rod is used to push the movable clamping block to slide and cooperate with the fixed clamping block to realize automatic correction of the welding fork. However, in this design, it is impossible to stably control the deformation position of the welding fork. Although it can ensure that the distance between the two forks of the welding fork meets the process requirements, it cannot ensure that the two forks are in a symmetrical state. In subsequent use, the welding fork is prone to uneven force. There are too few parameters for welding fork correction, and the quality of the welding fork cannot be guaranteed. For this reason, we propose an automatic correction tooling for welding forks to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and proposes an automatic correction tool for welding fork processing.

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

When the downward pressure structure drives the welding fork to move downward, the correction assembly can adjust the shape of the welding fork by using the correction block and the limiting assembly.

[0008] Preferably, the limit assembly includes a movable seat slidably connected to the workbench, the movable seat is detachably connected to a limit block, the movable seat is also fixedly connected to a guide plate, the lower end of the connecting frame is fixedly connected to a guide block, and the guide block is arranged to abut against the guide plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model provides a correction component. When the welding fork is corrected in size, it is only necessary to place the semi-finished welding fork on the correction component, and then start the downward pressing structure to drive the connecting frame to move downward, and then use the driving block to cooperate with the vertical frame to drive the correction block to correct the size of the welding fork.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 , an automatic correction tool for welding fork processing, comprising a workbench 1, a support frame 2 is fixedly connected to the workbench 1, a downward pressing structure is arranged on the support frame 2, and a correction component is arranged on the upper surface of the workbench 1 close to the support frame 2;

[0023] The pressing structure includes a hydraulic push rod 13, the lower end of which is fixedly connected to a mounting plate 14, and a forming die 15 is provided on the lower surface of the mounting plate 14, wherein the forming die is used to support between two forks of the welding fork;

[0024] The correction component includes an outer tube 3, a connecting frame 4 is slidably connected inside the outer tube 3, and the connecting frame 4 can only slide up and down inside the outer tube 3. A spring column 5 is provided at the lower end of the connecting frame 4, and the lower end of the spring column 5 is set against the upper surface of the workbench 1. The spring column 5 is a telescopic rod with a spring inside, and a vertical frame 6 is slidably connected to the connecting frame 4, and the vertical frame 6 can only slide horizontally on the connecting frame 4. There are two vertical frames 6 and the two vertical frames 6 are symmetrically arranged. A correction block 7 is detachably connected to the vertical frame 6. Since it is necessary to adapt to welding forks of different specifications, different correction blocks 7 need to be used according to the welding fork. A driving block 8 is also provided on the inner wall of the outer tube 3, and the driving block 8 is set against the vertical frame 6. A limiting assembly is also provided in the outer tube 3. When the downward pressure structure drives the welding fork to move downward, the correction assembly can use the correction block 7 to cooperate with the limiting assembly to adjust the shape of the welding fork;

[0025] In the above design, when the pressing assembly is running, it can drive the connecting frame 4 to move downward, and in the process of the connecting frame 4 moving downward, the driving block 8 drives the two vertical frames 6 to move in a direction close to each other, and then cooperates with the forming mold 15 to realize the correction of the welding fork. It should be noted that in the production process, the distance between the two forks of the welding fork is generally a positive deviation, which is convenient for the subsequent correction operation. The size between the welding forks is corrected, and the rebound factor needs to be taken into account. During the correction process, the distance between the two forks is a negative deviation. After the correction is completed, the distance between the forks will be within the allowable error of the process due to the rebound of the welding fork itself.

[0026] Furthermore, the limit assembly includes a moving seat 9 slidably connected to the workbench 1, a limit block 10 is detachably connected to the moving seat 9, a guide plate 11 is fixedly connected to the moving seat 9, and a guide block 12 is fixedly connected to the lower end of the connecting frame 4, and the guide block 12 is arranged to abut against the guide plate 11;

[0027] wherein the guide block 12 is L-shaped, and the upper and lower ends of the guide block 12 are provided with inclined surfaces, the guide plate 11 is provided with a sinking groove, and the inner walls of the upper and lower ends of the sinking groove are provided with inclined blocks.

[0028] In the above design, two movable seats 9 are provided, which are respectively located on both sides of the connecting frame 4, and the limit block 10 is also made according to the shape of the welding fork. During the correction process, as the connecting frame 4 moves downward, the guide block 12 can drive the guide plate 11 to move towards each other, so that the two limit blocks 10 further limit the welding fork, avoiding lateral deviation of the welding fork during the correction process, thereby ensuring the correction quality of the welding fork.

[0029] A placement plate 16 is provided at the center of the connecting frame 4, and the placement plate 16 is rotatably connected to the vertical frame 6. A protrusion is provided on one side of the limit block 10, and an elastic block is fixedly connected to the inner wall of the outer tube 3 near the protrusion.

[0030] In the above design, the placement plate 16 is used to temporarily fix the welding fork. When the user performs the welding fork correction operation, the lower end opening of the welding fork is placed on the placement plate 16 and the welding fork is straightened. Then the user performs the correction operation. In the process of the downward pressure assembly driving the welding fork and the connecting frame 4 to move downward, due to the limitation of the welding fork by the forming mold 15, the placement plate 16 cannot rotate at this time, but causes the elastic block to deform. After the welding fork correction is completed, when the spring column 5 drives the connecting frame 4 to move upward, the elastic block and the protrusion are against each other, causing the placement plate 16 to rotate to an inclined state, thereby causing the welding fork on the placement plate 16 to fall off, completing the unloading operation.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
