[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A large-format stamping auxiliary structure for processing elevator car tops includes a workbench 1, a stamping frame 2 bolted to the top of the workbench 1, a telescopic hydraulic cylinder 3 inside the stamping frame 2, an upper stamping die 4 bolted to the bottom of the telescopic hydraulic cylinder 3, a fitting buffer assembly 5 inside the upper stamping die 4, a bottom stamping die 6 bolted to the top of the workbench 1, a plate to be stamped 7 placed on the top of the bottom stamping die 6, and an adjustment and positioning mechanism 8 on the top of the workbench 1.

[0027] The adjustment and positioning mechanism 8 includes two mounting plates 81. The bottom of the mounting plate 81 is bolted to the top of the worktable 1. Telescopic electric cylinders 82 are provided on the front and rear sides inside the mounting plate 81. Anti-slip rubber push blocks 83 are bolted to the side of the telescopic electric cylinder 82 near the bottom stamping die 6. The side of the anti-slip rubber push block 83 near the plate to be stamped 7 is in contact with the plate to be stamped 7.

[0028] In this embodiment: during the large-format stamping process of the elevator car top, the worker first places the plate to be stamped 7 on the bottom stamping die 6 bolted to the top of the workbench 1. Then, the adjustment and positioning mechanism 8 set on the top of the workbench 1 starts to work. The two mounting plates 81 in the adjustment and positioning mechanism 8, since their bottoms are bolted to the top of the workbench 1, provide stable support for subsequent components. The telescopic electric cylinders 82 on the front and rear sides inside the mounting plates 81 start to activate, pushing the anti-slip rubber push blocks 83 bolted to them closer to the plate to be stamped 7 until the anti-slip rubber push blocks 83 contact the plate to be stamped 7, thus fixing the plate to be stamped 7 from multiple directions. Once the stamping position is set in the appropriate location to ensure accuracy, the telescopic hydraulic cylinder 3 inside the stamping frame 2 begins to work. Since the upper stamping die 4 is bolted to the bottom of the telescopic hydraulic cylinder 3, the telescopic hydraulic cylinder 3 extends downward, driving the upper stamping die 4 to move downward. The upper stamping die 4 cooperates with the bottom stamping die 6 to perform the stamping operation on the plate to be stamped 7, completing the stamping process of the large panel on the top of the elevator car. The fitting and buffering component 5 set inside the upper stamping die 4 can effectively fit the plate to be stamped 7 and effectively buffer it during stamping, protecting the surface quality of the plate to be stamped 7 and preventing the plate to be stamped 7 from shifting under instantaneous impact, thus affecting the stamping quality.

[0029] Specifically, such as Figure 3 As shown, the fitting buffer assembly 5 includes a buffer groove 51, which is formed inside the upper stamping die 4.

[0030] Specifically, such as Figure 3 As shown, a buffer plate 52 is slidably disposed inside the buffer groove 51, and an anti-slip and wear-resistant buffer pad 53 is bolted to the bottom of the buffer plate 52.

[0031] Specifically, such as Figure 3 As shown, several upper mounting sleeves 54 are bolted inside the buffer groove 51, and several lower mounting sleeves 55 are bolted to the top of the buffer plate 52. A spring 56 connects the interior of the upper mounting sleeves 54 and the lower mounting sleeves 55.

[0032] In this embodiment: when the telescopic hydraulic cylinder 3 drives the upper stamping die 4 to move downward, preparing to stamp the plate to be stamped 7, the fitting buffer assembly 5 set inside the upper stamping die 4 begins to function. The buffer groove 51 of the fitting buffer assembly 5 is opened inside the upper stamping die 4. When stamping begins, the anti-slip and wear-resistant buffer pad 53 at the bottom of the upper stamping die 4 first contacts the plate to be stamped 7. The anti-slip and wear-resistant buffer pad 53 is bolted to the bottom of the buffer plate 52. The buffer plate 52 is slidably set in the buffer groove 51. Under the action of pressure, the buffer plate 52 begins to slide upward in the buffer groove 51. Several upper... A spring 56 is connected between several lower mounting sleeves 55 bolted to the top of the mounting sleeve 54 and the buffer plate 52. As the buffer plate 52 slides upward, the spring 56 is compressed. The compression of the spring 56 plays a role in buffering and shock absorption, reducing the impact force on the plate to be stamped 7 and the upper stamping die 4 during the stamping process. At the same time, the anti-slip and wear-resistant buffer pad 53 can also prevent the plate to be stamped 7 from sliding during the stamping process, protecting the surface quality of the plate to be stamped 7. When the stamping is completed, when the telescopic hydraulic cylinder 3 drives the upper stamping die 4 to move upward, the spring 56 returns to its original state, and the buffer plate 52 slides downward back to its initial position under the action of the spring 56.

[0033] Specifically, such as Figure 2 As shown, mounting brackets 9 are bolted between the front and rear sides of the top of the two mounting plates 81, and a visual data analysis module 10 is bolted to the top of the mounting brackets 9.

[0034] Specifically, such as Figure 2 As shown, a visual recognition probe 11 is bolted to the bottom of the mounting bracket 9, and compensation lamps 12 are bolted to both sides of the bottom of the mounting bracket 9.

[0035] In this embodiment: After the positioning mechanism 8 performs initial positioning of the platen 7 to be stamped on the bottom stamping die 6, the visual recognition probe 11 and the visual data analysis module 10 mounted on the mounting bracket 9 begin to work. The mounting bracket 9 is bolted between the front and rear sides of the top of the two mounting plates 81, providing a mounting base for the visual recognition probe 11, the visual data analysis module 10, and the compensation lamp 12. The compensation lamps 12 bolted to both sides of the bottom of the mounting bracket 9 are turned on, providing sufficient light for the visual recognition probe 11 bolted to the bottom of the mounting bracket 9, ensuring that the visual recognition probe 11 can clearly acquire the image information of the platen 7 to be stamped. The visual recognition probe 11 transmits the collected information such as the position and shape of the plate to be stamped 7 to the visual data analysis module 10 bolted to the top of the mounting bracket 9. The visual data analysis module 10 analyzes and processes this information to determine whether the position of the plate to be stamped 7 is accurate. If there is a deviation in the position of the plate to be stamped 7, the visual data analysis module 10 will feed back the adjustment signal to the adjustment and positioning mechanism 8. The telescopic electric cylinder 82 in the adjustment and positioning mechanism 8 will be activated again to push the anti-slip rubber push block 83 to fine-tune the position of the plate to be stamped 7 until the visual data analysis module 10 determines that the position of the plate to be stamped 7 meets the accuracy requirements.

[0036] Specifically, such as Figure 4 As shown, the stamping frame 2 has two guide holes 13 inside, and a guide rod 14 is slidably arranged inside the guide hole 13. The bottom of the guide rod 14 is bolted to the top of the upper stamping die 4.

[0037] Specifically, such as Figure 5 As shown, the workbench 1 has a waste drop hole 15 inside, and a waste collection box 16 is bolted to the bottom of the workbench 1. The waste drop hole 15 is connected to the waste collection box 16.

[0038] In this embodiment: During the stamping motion of the upper stamping die 4 driven by the telescopic hydraulic cylinder 3, the two guide holes 13 and the guide rod 14 slidably set inside the stamping frame 2 play a role. The bottom of the guide rod 14 is bolted to the top of the upper stamping die 4. When the telescopic hydraulic cylinder 3 drives the upper stamping die 4 to move up and down, the guide rod 14 slides in the guide hole 13. The cooperation between the guide hole 13 and the guide rod 14 ensures that the upper stamping die 4 moves vertically up and down, avoiding deviation during the stamping process and ensuring the accuracy and quality of the stamping. During the stamping process, waste material is generated. The waste material drop hole 15 inside the worktable 1 plays a role at this time. The waste material generated by the stamping falls down through the waste material drop hole 15. Since a waste material collection box 16 is bolted to the bottom of the worktable 1, the fallen waste material will be collected in the waste material collection box 16, which is convenient for subsequent cleaning and processing and keeps the working environment clean.

[0039] Working principle: The operator first places the plate to be stamped 7 on the bottom stamping die 6 bolted to the top of the workbench 1. Then, the adjustment and positioning mechanism 8 on the top of the workbench 1 starts to work. The bottom of the two mounting plates 81 of this mechanism is bolted to the top of the workbench 1, providing stable support for subsequent components. The telescopic electric cylinders 82 on the front and rear sides inside the mounting plates 81 are activated, pushing the anti-slip rubber pusher 83 towards the plate to be stamped 7 and making contact, fixing the plate to be stamped 7 from multiple directions to ensure accurate stamping position. Then, the vision recognition probe 11 and vision data analysis module 10 mounted on the mounting frame 9 start to operate. The mounting frame 9 is bolted to the front and rear sides of the top of the two mounting plates 81. Between the sides, the compensation lights 12 on both sides of the bottom of the mounting frame 9 are turned on to provide sufficient light for the visual recognition probe 11, enabling it to clearly collect information such as the position and shape of the plate to be stamped 7, and transmit it to the visual data analysis module 10. This module analyzes and processes the information. If there is a deviation in the position of the plate to be stamped 7, it will feed back the adjustment signal to the adjustment and positioning mechanism 8. The telescopic electric cylinder 82 will start again to fine-tune the position of the plate to be stamped 7 until the accuracy requirement is met. After that, the telescopic hydraulic cylinder 3 inside the stamping frame 2 works. Because its bottom is bolted to the upper stamping die 4, it drives the upper stamping die 4 to move downward, cooperating with the bottom stamping die 6 to stamp the plate to be stamped 7. When preparing for stamping, the fitting buffer assembly 5 inside the upper stamping die 4 comes into play. The buffer groove 51 is opened inside the upper stamping die 4. The anti-slip and wear-resistant buffer pad 53 at the bottom of the upper stamping die 4 first contacts the plate to be stamped 7. The anti-slip and wear-resistant buffer pad 53 is bolted to the bottom of the buffer plate 52 that slides in the buffer groove 51. Under pressure, the buffer plate 52 slides upward in the buffer groove 51. The spring 56 connecting the upper mounting sleeve 54 in the buffer groove 51 and the lower mounting sleeve 55 at the top of the buffer plate 52 is compressed, which plays a role in buffering and shock absorption, reducing the impact force on the plate to be stamped 7 and the upper stamping die 4 during the stamping. The anti-slip and wear-resistant buffer pad 53 can also prevent the plate to be stamped 7 from being pressed. Sliding protects the surface quality. After stamping is completed, the telescopic hydraulic cylinder 3 drives the upper stamping die 4 to move upward. The spring 56 returns to its original state, and the buffer plate 52 returns to its initial position. During the stamping process, the two guide holes 13 inside the stamping frame 2 and the guide rod 14 that is slidably set inside work together. The bottom of the guide rod 14 is bolted to the top of the upper stamping die 4 to ensure that the upper stamping die 4 moves vertically up and down, avoids stamping deviation, and ensures stamping accuracy and quality. The waste generated by stamping falls downward through the waste drop hole 15 opened inside the worktable 1. The waste collection box 16 bolted to the bottom of the worktable 1 collects the waste, which is convenient for cleaning and keeps the working environment clean.
