Description

Technical Field

[0001] The utility model belongs to the technical field of welding fixtures, and in particular relates to a piece unloading mechanism of a welding fixture. Background Art

[0002] The product parts will have a slight deformation during the welding process in the fixture. After welding is completed, they cannot be directly unloaded manually. External force is needed to lift the cylinder to complete the unloading. At present, the unloading of product parts in China requires four cylinders to lift the product parts. This unloading method is costly, and multiple cylinders are prone to being out of sync. During the unloading process, the product parts are prone to tilting, affecting product quality. In addition, the position of the cylinder is not easy to adjust. When lifting partially hollowed-out products, it is not easy to change the position of the support block for matching use, and the applicability is poor. For this reason, a welding fixture unloading mechanism is specially provided to solve the above technical problems. Utility Model Content

[0003] In view of the unloading mechanism in the prior art, the four-cylinder lifting and unloading method adopted has the problems of high unloading cost, easy asynchronism between multiple cylinders, easy tilting of product parts during unloading, and affecting product quality. The utility model provides an unloading mechanism for a welding fixture, by slidingly setting four adjustable support blocks on the upper surface of the mounting plate, and installing a hydraulic telescopic rod and a directional rod on the lower surface of the mounting plate. In actual operation, by utilizing the telescopic characteristics of the hydraulic telescopic rod, the mounting plate can be moved up and down in the vertical direction. At the same time, the four support blocks work together to ensure that the products in the fixture are lifted and unloaded synchronously from four points. This design not only ensures that the product can be smoothly and stably detached from the fixture, but also effectively avoids the risk of product tilting caused by asynchronous lifting. In addition, the new design not only significantly reduces the manufacturing cost, but also meets the lifting requirements of special hollow products by adjusting the position of the support blocks, thereby significantly enhancing the adaptability and practicality of the mechanism. The invention effectively solves the problems of the unloading mechanism in the prior art, such as high cost, easy asynchronism between multiple cylinders, easy tilt of product parts during unloading, and affecting product quality. The specific technical solution is as follows:

[0004] A welding fixture unloading mechanism comprises a mounting plate, a hydraulic telescopic rod is fixedly mounted on the lower surface of the mounting plate, two directional rods are symmetrically fixedly mounted on the lower surface of the mounting plate, the outer surfaces of the directional rods are sleeved with directional shaft sleeves, and four support blocks with adjustable positions are mounted on the upper surface of the mounting plate, and the outer surfaces of the support blocks are sleeved with elastic rubber sleeves.

[0005] In the above technical solution, the mounting plate is in the shape of an "I" character, the lower surface of the support block is integrally formed with a slider symmetrically arranged, the slider is installed in the mounting plate, the upper surface of the support block is provided with a groove, and the groove is threaded with a clamping bolt, and the lower surface of the clamping bolt is in contact with the upper surface of the mounting plate.

[0006] In the above technical solution, the upper surface of the elastic rubber sleeve is penetrated by a through opening.

[0007] In the above technical solution, the upper surface of the mounting plate is horizontally engraved with length markings equidistantly from the middle to both sides, and a triangular positioning window is opened through the upper surface of the support block, and the triangular positioning window is located directly above the length marking.

[0008] In the above technical solution, the lower surface of the elastic rubber sleeve is provided with a tightening part, the outer surface of the support block is fixedly installed with a limiting rib, and the tightening part is tightened on the outer surface of the limiting rib.

[0009] Compared with the prior art, the unloading mechanism of the welding fixture of the utility model has the following beneficial effects:

[0010] The utility model has four support blocks with adjustable positions slidably arranged on the upper surface of the mounting plate, and a hydraulic telescopic rod and a directional rod are installed on the lower surface of the mounting plate. In practical applications, the mounting plate can be moved vertically up and down with the help of the telescopic function of the hydraulic telescopic rod, and the four support blocks work together to synchronously lift and unload the products in the fixture from four points to ensure that the products can be taken out horizontally. This new design not only significantly reduces the manufacturing cost, but also adapts to the lifting requirements of special hollow products by adjusting the position of the support blocks, thereby greatly enhancing the adaptability and practicality of the mechanism.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-Figure 5 , the present invention provides a technical solution:

[0019] A workpiece unloading mechanism of a welding fixture includes a mounting plate 1. A hydraulic telescopic rod 2 is fixedly installed on the lower surface of the mounting plate 1. Two guiding rods 3 are symmetrically and fixedly installed on the lower surface of the mounting plate 1. Guiding bushings 31 are sleeved on the outer surfaces of the guiding rods 3. Four supporting blocks 4 with adjustable positions are installed on the upper surface of the mounting plate 1. Elastic rubber sleeves 5 are sleeved on the outer surfaces of the supporting blocks 4;

[0020] When this mechanism is actually used, the guiding bushing 31 is fixedly installed through the clamping range below the fixture, and the bottom of the hydraulic telescopic rod 2 is fixedly installed below the clamping range in the fixture. When processing a product, after placing the product in the fixture, the mounting plate 1 and the supporting blocks 4 function to lift the bottom of the product. When the processing of the product in the fixture is completed, after releasing the fixation of the product, the hydraulic telescopic rod 2 can be extended to drive the mounting plate 1, the supporting blocks 4 and the elastic rubber sleeves 5 to move upward, and the four supporting blocks 4 are used to lift and move the product from four points, so as to complete the unloading operation. Compared with the prior art, this structure can use one hydraulic telescopic rod 2, a mounting plate 1 and four supporting blocks 4 to synchronously lift and unload the product in the fixture from four points, ensuring that the product can be taken out horizontally while reducing the manufacturing cost.

[0021] It should be noted that, as Figure 1 shown, the mounting plate 1 is in the shape of a "work" character. As Figure 3 shown, sliders are integrally formed and symmetrically arranged on the lower surfaces of the supporting blocks 4. The sliders are installed in the mounting plate 1. Grooves 42 are formed on the upper surfaces of the supporting blocks 4. Tightening bolts 6 are installed through the grooves 42 in a threaded manner. The lower surfaces of the tightening bolts 6 are in contact with the upper surface of the mounting plate 1. After the bottom ends of the tightening bolts 6 are tightened against the upper surface of the mounting plate 1, the positions of the supporting blocks 4 can be fixed;

[0022] When unloading the hollow product, the position of the support block 4 needs to be adjusted. When adjusting, loosen the tightening bolt 6 to make it detach from the upper surface of the mounting plate 1, and then slide the support block 4 on the upper surface of the mounting plate 1 to adjust the position. After sliding the support block 4 to a suitable lifting position, retighten the tightening bolt 6 to fix the position of the support block 4.

[0023] In addition, when adjusting the support block 4, in order to accurately adjust it to the appropriate position, Figure 1 or Figure 5 As shown, through openings are opened through the upper surface of the elastic rubber sleeve 5, and length marks 11 are horizontally engraved equidistantly from the middle to both sides of the upper surface of the mounting plate 1, and a triangular positioning window 41 is opened through the upper surface of the support block 4. The triangular positioning window 41 is located directly above the length mark 11. During the process of adjusting the position of the support block 4, the positional relationship between the support block 4 and the length mark 11 can be observed through the through opening and the triangular positioning window 41, so as to determine whether the appropriate lifting position has been reached.

[0024] In addition, in order to prevent the elastic rubber sleeve 5 from easily falling off the support block 4 during use, Figure 5 As shown, a tightening portion 51 is provided on the lower surface of the elastic rubber sleeve 5. Figure 4 As shown, the limiting ribs 43 are fixedly installed on the outer surface of the support block 4 , and the tightening part 51 can be used to tighten the outer surface of the limiting ribs 43 , so as to prevent the elastic rubber sleeve 5 from easily detaching from the support block 4 .
