Through the oppositely arranged first forward cylinder 1 and second forward cylinder 2 of ingenious design and the first pressing cylinder 3 and second pressing cylinder 4 fixed on the slider driven by them respectively, the accurate clamping and positioning of framework 8 are realized. When framework 8 is placed between left pressing block 5 and right pressing block 6, first pressing cylinder 3 and second pressing cylinder 4 can work cooperatively, drive left pressing block 5 and right pressing block 6 to apply uniform and controllable pressure to framework 8, so as to ensure the stability and accuracy of framework 8 during assembly.

[0022] In addition, the mechanism is particularly provided with pressing mechanism 7 above framework 8, which not only further enhances the fixing effect of framework 8 during assembly, but also enables each part of framework 8 to be more closely combined together through the pressing action of pressing mechanism 7, improving the overall structural strength and durability of framework 8.

[0023] In this embodiment, the first front air cylinder 1, the second front air cylinder 2, the first pressing air cylinder 3, and the second pressing air cylinder 4 are fixed on the plane through the support 9. By stably fixing all the air cylinders on the plane through the support 9, the stability and reliability of the entire mechanism are ensured. This design not only improves the anti-vibration capability of the mechanism, but also ensures the accurate positioning of the air cylinders during operation and the stability of long-term operation, thereby improving the accuracy and consistency of the frame assembly.

[0024] Specifically, the pressing mechanism 7 includes a pressing air cylinder 71, the output shaft of the pressing air cylinder 71 is provided with a lifting block 72, the bottom of the lifting block 72 is provided with a height adjusting rod 73, the height adjusting rod 73 is threadedly connected with the lifting block 72, and the bottom of the height adjusting rod 73 is connected with a pressing plate 74. The design of the pressing mechanism 7 realizes the upward pressing of the frame 8. The lifting block 72 is driven to move up and down by the pressing air cylinder 71, thereby driving the pressing plate 74 to exert pressure on the frame 8. The threaded connection design of the height adjusting rod 73 and the lifting block 72 enables the size and position of the pressing force to be flexibly adjusted according to actual needs, thereby improving the adaptability and flexibility of the mechanism.

[0025] Further, the top of the pressing plate 74 is provided with a guide rod 741, the bottom of the height adjusting rod 73 is provided with a slot, the guide rod 741 is inserted into the slot in a fitting manner, the guide rod 741 is externally sleeved with a spring 75, the top end of the spring 75 is welded and fixed with the height adjusting rod 73, and the bottom end of the spring 75 is welded and fixed with the pressing plate 74. The insertion fitting of the guide rod 741 and the slot ensures the stability and guidance of the pressing plate 74 during upward and downward movement. The spring 75 serves as a buffer and shock absorber, avoiding the impact and damage of the pressing plate 74 on the frame 8 during pressing, and also helps to maintain the uniformity and stability of the pressing.

[0026] Further, the right pressing block 6 and the left pressing block 5 have the same structure, the right pressing block 6 includes two symmetrical movable blocks 64, and the movable blocks 64 are rotatably connected with the outer wall of the sliding blocks of the first front air cylinder 1 and the second front air cylinder 2 through the pin shaft 61. The same structure design of the right pressing block 6 and the left pressing block 5 simplifies the complexity of the mechanism and reduces the manufacturing cost. The rotatable connection of the movable blocks 64 with the outer wall of the sliding blocks through the pin shaft 61 enables the pressing block to be finely adjusted according to actual conditions, so as to better adapt to frames 8 of different shapes and sizes, thereby improving the universality and flexibility of the mechanism.

[0027] Further, one end of the right pressing block 6 is provided with a pressing opening 62, and the other end of the right pressing block 6 is provided with a stress opening 63, and the inner sides of the pressing opening 62 and the stress opening 63 are both inclined surface structures. The inclined surface structure of the pressing opening 62 and the stress opening 63 can make the pressing block better contact with the framework 8 and apply pressure during the pressing process, and also help to uniformly distribute the pressure to each part of the framework 8, thereby improving the uniformity and effect of the pressing. In addition, the inclined surface structure also facilitates the installation and debugging of the pressing block, and reduces the maintenance difficulty of the mechanism.

[0028] Further, the pressing cylinder 71 is supported and fixed by the support frame. The pressing cylinder 71 is supported and fixed by the support frame, which ensures the stability and reliability of the pressing cylinder 71 during the working process. This design not only improves the carrying capacity of the pressing cylinder 71, but also avoids the situation that the pressing effect is affected due to the vibration or deviation of the cylinder, thereby ensuring the high precision and high efficiency of the framework assembly.

[0029] The mechanism for assembling the framework step by step of the utility model in use, first of all, the framework 8 is placed between the left pressing block 5 and the right pressing block 6. Since the left pressing block 5 and the right pressing block 6 are driven by the first pressing cylinder 3 and the second pressing cylinder 4 respectively, and the two pressing cylinders are fixed on the sliding block driven by the first advancing cylinder 1 and the second advancing cylinder 2 respectively, the whole mechanism has high flexibility and adjustability.

[0030] Start the first advancing cylinder 1 and the second advancing cylinder 2, and they respectively drive the sliding block to move in the opposite direction, thereby driving the first pressing cylinder 3 and the second pressing cylinder 4 to approach the framework 8. When the left pressing block 5 and the right pressing block 6 contact the framework 8, the first pressing cylinder 3 and the second pressing cylinder 4 start to work, and their output shafts push the left pressing block 5 and the right pressing block 6 to apply pressure to the framework 8, realizing the accurate clamping and positioning of the framework 8. Since the right pressing block 6 and the left pressing block 5 are the same structure, and each contains two symmetrically arranged movable blocks 64, the movable blocks 64 are rotatably connected with the outer wall of the sliding block through the pin shaft 61, so they can be adjusted according to the shape and size of the framework 8, to ensure the stability and accuracy of clamping.

[0031] After the skeleton 8 is clamped and positioned, the pressing cylinder 71 is started. The output shaft of the pressing cylinder 71 pushes the lifting block 72 to move downward, and in turn drives the height adjusting rod 73 and the pressing plate 74 to exert pressure on the skeleton 8. The threaded connection between the height adjusting rod 73 and the lifting block 72 allows the size and position of the pressing force to be adjusted according to actual needs. This is achieved by rotating the height adjusting rod 73, thereby changing the contact pressure and position between the pressing plate 74 and the skeleton 8. The guide rod 741 and the insertion of the slot ensure the stability and guidance of the pressing plate 74 during the up and down movement. At the same time, the spring 75 is provided to play a buffering and damping role, avoiding impact and damage to the skeleton 8 during pressing.

[0032] Under the continuous action of the pressing cylinder 71, the pressing plate 74 exerts sufficient pressure on the skeleton 8, so that the parts of the skeleton 8 are more closely combined together. This process improves the overall structural strength and durability of the skeleton 8. When the pressing reaches the predetermined requirement, the pressing cylinder 71 is turned off, and the lifting block 72, the height adjusting rod 73 and the pressing plate 74 slowly rise to the initial position under the action of the spring 75. Subsequently, the first pressing cylinder 3 and the second pressing cylinder 4 are turned off, and the left pressing block 5 and the right pressing block 6 release the pressure on the skeleton 8. Finally, the first advancing cylinder 1 and the second advancing cylinder 2 move the slide and the pressing cylinder back to the initial position, ready for the next assembly.

[0033] The above steps are repeated to achieve automatic, efficient and precise assembly of the step-by-step skeleton.

[0034] Finally, it should be noted that the first advancing cylinder 1, the second advancing cylinder 2, etc. in the embodiment, and the electronic components in the above components are all general standard components or components known to those skilled in the art, and their structure and principle can be known by those skilled in the art through technical manuals or through conventional experimental methods.
