Description

Technical Field

[0001] This utility model relates to the technical field of telescopic ladder assembly equipment, specifically to an automatic drilling and assembly machine for telescopic ladders. Background Technology

[0002] In the manufacturing process of telescopic ladders, drilling and pin assembly are two crucial steps. Traditionally, these processes largely relied on manual operation, which was not only inefficient but also difficult to guarantee in terms of processing accuracy and consistency. With the continuous development of automation technology, more and more manufacturing companies are seeking to improve production efficiency and product quality through automated equipment.

[0003] However, most existing automated production equipment for telescopic ladders is single-function, often only capable of performing one task in drilling or pin assembly, and its automation level is low, still requiring a significant amount of manual assistance. Furthermore, these machines often lack flexibility in their structural design, making it difficult to adapt to the production needs of telescopic ladders of different specifications and models.

[0004] Therefore, it is particularly important to develop an automatic drilling and assembly machine for telescopic ladders that integrates drilling and pin assembly functions and possesses a high degree of automation and flexibility. This equipment can not only significantly improve production efficiency and reduce labor costs, but also ensure processing accuracy and consistency, thereby enhancing product quality and market competitiveness.

[0005] While some similar automated equipment exists on the market, they still have many shortcomings in terms of structural design, functional implementation, and degree of automation. For example, some equipment has an unreasonable drilling mechanism design, resulting in low drilling accuracy; some equipment's pin assembly mechanism lacks flexibility and is difficult to adapt to different specifications of pins and telescopic ladders; and some equipment has a low degree of automation and still requires a lot of manual intervention and operation.

[0006] Therefore, an automatic drilling and assembly machine for telescopic ladders has become a problem that urgently needs to be solved. Utility Model Content

[0040] The pushing assembly 7 of this utility model includes a movable support frame 26, a horizontal pull plate 27, a movable pushing cylinder 28, and a top plate slide 29. The lower part of the movable support frame 26 is fixedly connected to the transmission belt 23 and the bottom is slidably connected to the guide rail on the outside of the frame 1.

[0041] The clamping mechanism 2 of this utility model includes a clamping fixing plate 30, an upward pushing cylinder 31, a clamping support plate 32, a clamping cylinder 33, a fixing sleeve pressure block 34, and a telescopic ladder placement fixture 35.

The clamping cylinder 33 pushes the fixing sleeve pressure block 34 to press the telescopic ladder on the telescopic ladder placement fixture 35 to ensure the stability of the telescopic ladder during the processing.

[0042] The specific implementation process of this utility model, an automatic drilling and assembly machine for telescopic ladders, is as follows:

[0043] The worker places the telescopic ladder material on the telescopic ladder placement fixture 35 of the clamping mechanism 2 and starts the clamping cylinder 33 to clamp the telescopic ladder.

[0044] Then, the moving push cylinder 28 is activated to lower the top plate slide 29 so that it is positioned between the climbing bars of the telescopic ladder; the transmission drive motor 21 of the transmission assembly 6 is activated, and the transmission belts 23 on both sides of the frame 1 move synchronously through the synchronous shaft 22. Through the coordinated action of the synchronous wheel 24 and the auxiliary wheel 25, the entire push assembly 7 is moved, so that the top plate slide 29 moves and contacts the climbing bars of the telescopic ladder, pushing the entire telescopic ladder to move until the end of the telescopic ladder moves to the designated position at the end of the frame 1. The telescopic ladder can be further moved by setting a limit block to achieve the designated position.

[0045] Start the electric drill 10 and drilling cylinder 9 of the drilling mechanism 4. The drilling cylinder 9 pushes the electric drill 10 forward to drill holes in the side wall of the telescopic ladder. The drilling mechanism 4 is set with several groups on the frame 1 to drill holes in different sections of the telescopic ladder. After drilling is completed, the electric drill 10 stops running and the drilling cylinder 9 drives the electric drill 10 back to the initial position.

[0046] The pin assembly mechanism 5 is activated, and the direction adjustment cylinder 12 drives the cylinder transmission frame to rotate, thereby pushing the pin outlet at the lower end of the pin guide plate 15 to align with the pin channel 18, so that the pins fall into the pin channel 18. After the pins are filled, the direction adjustment cylinder 12 drives the pin guide plate 15 to reset. The pin pushing cylinder 17 is activated to push the pin channel 18 upward to the drilling position of the telescopic ladder. The drilling cylinder 9 is activated to push the pushing plate 11 forward, which in turn pushes the extrusion handle 20 on the pin guide sleeve 19 to push the pin into the hole drilled in the telescopic ladder to complete the assembly of the telescopic ladder. After the assembly is completed, the drilling cylinder 9 and the pin pushing cylinder 17 respectively drive their respective connected structures to reset.

[0047] Once the telescopic ladder is assembled, the moving push cylinder 28 drives the top plate slide 29 to reset. At the same time, the clamping cylinder 33 drives the fixed sleeve pressure block 34 to reset, and the upward push cylinder 31 drives the clamping support plate 32 to reset. In other words, all the mechanisms of the entire device are reset, and the workers remove the telescopic ladder.

[0048] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
