DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] 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.

[0022] This utility model provides, for example Figures 1-3 The fork carriage slant head welding and positioning fixture shown includes upper and lower mounting plates 1, left and right column side plates 2, and slant head positioning plate 3. The upper and lower mounting plates 1 and the left and right column side plates 2 are interlocked with each other, and the upper and lower mounting plates 1 and the left and right column side plates 2 together form a "U" frame structure. The left and right column side plates 2 are provided with slots for mounting the slant head positioning plate 3. The slant head positioning plate 3 is movably mounted with mounting bushings 4. Adjusting rods 5 are rotatably mounted on both left and right column side plates 2. Pull rods 6 are rotatably mounted on both ends of the adjusting rods 5. The other end of the pull rods 6 is rotatably mounted on the bottom end of the slant head positioning plate 3. Upper and lower clamping plates 7 are fixedly mounted on the inner side of the upper and lower mounting plates 1. Connecting rods 9 are movably mounted inside the upper and lower clamping plates 7. The slant head positioning plate 3 is rotatably mounted on one end of the connecting rods 9. The upper and lower clamping plates 7 and the connecting rods 9 are provided with pin holes 8. The upper and lower clamping plates 7 and the connecting rods 9 are connected by pins.

[0023] When installing the fork carriage slant head by adjusting the angle of the slant head positioning plate 3, the upper and lower clamping plates 7 and the connecting rod 9 are fixed with pins. Then, by manually rotating the adjusting rod 5, the adjusting rod 5 drives the pull rod 6. Because the slant head positioning plate 3 is rotatably mounted on the connecting rod 9, the pull rod 6 pulls the slant head positioning plate 3 to rotate on the connecting rod 9, thereby adjusting the angle of the mounting bushing 4 to install the fork carriage slant head. This tooling, through the cooperation of the slant head positioning plate 3 and the mounting bushing 4, can accurately position the fork carriage slant head, improve welding accuracy, and reduce welding errors. The combined design of the adjusting rod 5, the pull rod 6, and the slant head positioning plate 3 allows the tooling to adjust the angle and position according to different specifications of slant heads, making it widely adaptable. The upper and lower mounting plates 1 and the left and right upright side plates 2 of the "U"-shaped frame structure provide stable support. The connections between the various components of the tooling are simple, the operation is convenient, and installation and adjustment can be carried out quickly, improving work efficiency.

[0024] The inclined shaft head positioning plate 3 is provided with a sliding groove 10, and the left and right column side plates 2 are movably installed with a snap-fit ​​plate 11. The size of the snap-fit ​​plate 11 is adapted to the sliding groove 10. The left and right column side plates 2 are provided with a mounting groove 12 inside. The inclined shaft head positioning plate 3 is slidably connected to the mounting groove 12.

[0025] The inclined shaft head positioning plate 3 and the snap-fit ​​plate 11 are slidably connected by the sliding groove 10 and the snap-fit ​​plate 11. First, remove the pin between the upper and lower clamping plates 7 and the connecting rod 9. Press down the snap-fit ​​plate 11 so that the inclined shaft head positioning plate 3 is slidably installed on the left and right column side plates 2. By manually rotating the adjusting rod 5, the left and right column side plates 2 slide on the inclined shaft head positioning plate 3 under the traction of the pull rod 6 due to the limitation of the snap-fit ​​plate 11, so as to enter the mounting groove 12 on the left and right column side plates 2, thereby achieving a slight adjustment of the distance between the inclined shaft head positioning plates 3. The design of 1, combined with the mounting groove 12, enables the slant head positioning plate 3 to achieve high-precision position adjustment, which helps to more accurately position the slant head, thereby improving the accuracy of welding, ensuring the quality of the fork carriage, and reducing subsequent use problems caused by the position deviation of the slant head. This design allows for flexible position adjustment of the slant head positioning plate 3. Whether during installation or when dealing with different batches or specifications of slant heads, the position of the slant head positioning plate 3 can be easily changed by moving the snap-fit ​​plate 11 in the slide groove 10, enhancing the versatility of the tooling.

[0026] A buckle block 13 is fixedly installed on the inner side of the inclined shaft head positioning plate 3, and a buckle 14 is fixedly installed on the bottom of the upper and lower mounting plates 1.

[0027] When installing the fork carriage onto the positioning fixture, the upper and lower crossbeams of the fork carriage are fixedly connected by clips 14, and the vertical mounting plate on the fork carriage is secured by clip blocks 13.

[0028] The connection between the snap-fit ​​block 13 and the snap-fit ​​14 greatly enhances the stability of the inclined shaft head positioning plate 3 in the tooling. Through this additional connection method, in conjunction with other positioning and fixing structures, the possibility of shaking and displacement of the inclined shaft head positioning plate 3 during the welding operation is reduced, ensuring the accurate positioning of the inclined shaft head and helping to improve the welding quality. The design of the snap-fit ​​14 and the snap-fit ​​block 13 makes the installation process of the inclined shaft head positioning plate 3 more convenient. The installer can complete the installation operation more easily, and there is a clear operating procedure when disassembly is required, which improves the assembly and maintenance efficiency of the tooling and reduces maintenance time and cost.

[0029] The mounting bushing 4 is installed through the inclined shaft head positioning plate 3. The mounting bushing 4 has a mounting hole 16 on the side closer to the inside of the frame structure, and a push rod 15 is movably installed on the side of the mounting bushing 4 away from the mounting hole 16.

[0030] When welding the roller shaft to the fork carriage, the roller shaft is first placed inside the mounting sleeve 4. By pushing the mounting sleeve 4, it is slowly moved closer to the position on the fork carriage where the roller shaft is mounted. Then, push rod 15 is pushed, which pushes the roller shaft inside the mounting sleeve 4 to fit against the fork carriage. Finally, the roller shaft is welded and fixed using welding equipment, thus achieving the welding and fixing of the fork carriage roller shaft.

[0031] The design of the bushing 4 penetrating the inclined shaft head positioning plate 3 and its own structure provide precise initial positioning for the roller shaft. Throughout the operation, it ensures that the roller shaft is accurately aligned with the installation position of the fork carriage, greatly improving the accuracy of the welding position and reducing welding deviation. Before welding, the push rod 15 makes the roller shaft fit tightly against the fork carriage, and this fit remains stable during the welding process. This effectively prevents welding defects caused by the roller shaft shaking or displacement during welding, ensuring the stability and quality of the welding and improving the reliability of the fork carriage roller shaft after welding.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
