Technical Field

[0001] The utility model relates to the technical field of tire membrane clamps for body sheet metal, in particular to a split type detachable tire mold replacement mechanism. Background Art

[0002] Cars have become very common in today's social life, and are showing a trend of gradual growth. With the gradual increase in the number of cars owned, the competitive pressure among various automobile manufacturers is becoming greater and greater, and the replacement time of car models is becoming shorter and shorter, especially in today's new energy models.

[0003] When a car model is replaced, the outer body usually has the largest range of changes, which is commonly known as the body in white. During the production process of the car body in white, the inner and outer panels will be exposed to the edge wrapping and pressing. At this time, the membrane clamp is needed. The quality of the membrane clamp largely determines the quality of the body surface. Most of the membranes used now are one-piece membranes, which are inconvenient to process and transport. Moreover, if the surface of the membrane is accidentally damaged, the entire membrane will need to be pulled back to the processor for repair at the least, or the entire membrane will be scrapped and need to be reprocessed at the worst. This is a considerable cost challenge for the production and processing costs of the model. Utility Model Content

[0004] The utility model aims to provide a split-type detachable tire mold replacement mechanism, aiming to overcome the defects of the prior art and solve the problem of inconvenient processing and transportation of the integrated tire membrane.

[0005] To this end, the utility model proposes a split detachable tire mold replacement mechanism, including a split tire membrane head and a lower tire membrane casting structure; the split tire membrane head is composed of a plurality of tire membrane heads assembled together; each of the split tire membrane heads is positioned with the lower tire membrane casting structure by a positioning pin; the split tire membrane head is also locked on the lower tire membrane casting structure in sequence by a plurality of screws to obtain a complete tire membrane upper surface, and the upper surface of the tire membrane upper surface is in contact with the outer panel surface of the vehicle body panel.

[0006] As a preferred technical solution of the present application, a waist-shaped connecting block is provided at the upper end of the lower cast structure of the fetal membrane, and the waist-shaped connecting block cooperates with a groove opened at the bottom of the split fetal membrane head.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] like Figure 1 As shown, the entire split-type detachable tire mold replacement mechanism is in an initial state. At this time, the fetal membrane is composed of a split fetal membrane head 2 and a lower fetal membrane casting structure 3, a mounting plate 1 and a precise positioning guide mechanism 5. The split fetal membrane head 2 is mounted on the lower fetal membrane casting structure 3. The above two constitute the fetal membrane body, and the fetal membrane body is finally mounted on the mounting plate 1.

[0025] like Figure 2 As shown, the split membrane head 2 is composed of several membrane heads assembled together, and when the split membrane head 2 is installed, the split membrane head 2 is positioned on the lower membrane casting structure 3 by two positioning pins 9, and then the split membrane head 2 is locked on the lower membrane casting structure 3 by a plurality of screws 8. Each part of the split membrane head is installed on the lower membrane casting structure 3 in turn to obtain a complete membrane upper surface, and the upper surface of the membrane upper surface is in contact with the outer panel surface of the vehicle body panel 11.

[0026] Each of the split type fetal membrane heads 2 is provided with a lifting hole, in which a lifting ring 7 is installed. The lifting ring 7 is installed in the lifting hole of the split type fetal membrane head 2, and the split type fetal membrane head 2 is moved to the lower part casting structure 3 of the fetal membrane by a crane.

[0027] like Figure 3 As shown, the body panel 11 is placed on the membrane body, and a plurality of precise positioning guide mechanisms 5 are fixedly mounted on the mounting plate 1 and distributed around the membrane body; the precise positioning guide mechanisms 5 limit the position of the body panel 11. In addition, each membrane head of the split membrane head 2 is provided with a suction cup 4 on its upper surface, and the rear end of the suction cup 4 is connected to an exhaust device, and the suction cup 4 adsorbs the outer plate of the body panel 11.

[0028] like Figure 1As shown, the fetal membrane clamp is also provided with at least one proximity switch 6. When the vehicle body panel 11 reaches the surface of the fetal membrane, the proximity switch 6 detects that the panel is in place and the fetal membrane starts to work.

[0029] like Figure 2 As shown, the split membrane head 2 can only support the four sides of the body panel 11. For this purpose, a plurality of support blocks 10 are arranged in the center of the membrane. The plurality of support blocks 10 support the outer panel of the body panel 11 and prevent the suction force of the suction cup 4 from being too large, which would cause defects on the surface of the body panel 11.

[0030] like Figure 4 As shown, a plurality of waist-shaped holes are provided on the upper end surface of the lower cast structure 3 of the fetal membrane, and waist-shaped connecting blocks 12 are installed in the waist-shaped holes. The waist-shaped connecting blocks 12 protrude from the surface of the lower cast structure 3 of the fetal membrane, and cooperate with the groove provided at the bottom of the split fetal membrane head 2, thereby making the positioning of the split fetal membrane head 2 more precise and realizing high-quality rolling process.

[0031] With the popularization of vehicles, the technology of automobiles is becoming more and more mature. In the current body production process, especially in the production process of four doors and two covers, the rolling process is used more and more. Most of the rolling will use the tire membrane. Nowadays, the tire membrane structure is mostly one-piece casting, which has high requirements for design and processing. If there is an error, it is likely to lead to the scrapping of the entire tire membrane or quality problems of the body product. Therefore, if the reprocessing cost is high and the processing cycle is long, it will affect the production of the production line.

[0032] The split-type detachable tire mold replacement mechanism provided by the utility model also has the following characteristics: 1. The processing cycle is shortened, and the processing quality of a single split tire membrane is higher, and the quality of the finished product of the vehicle body outer covering is better. 2. If the tire membrane body is damaged, the damaged area of ​​the tire membrane can be replaced separately, so that the entire tire membrane is not pulled back to the processor for overall processing or even scrapped and reprocessed, which greatly reduces the transportation and processing costs and the time for rework. 3. The weight of the tire membrane is reduced, the processing cost is reduced, and the tire membrane is lightweight.

[0033] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
