Description

Technical Field

[0001] This utility model relates to the technical field of telescopic ladder assembly equipment, specifically to a drilling and pin assembly mechanism. Background Technology

[0002] In the manufacturing process of telescopic ladders, drilling and pin assembly are two crucial steps. Traditional production methods often rely on manual labor for these steps, which is not only inefficient but also poses safety hazards. Especially in the drilling stage, manual operation makes it difficult to ensure the accuracy and consistency of the drilling positions, thus affecting the structural strength and stability of the telescopic ladder. Similarly, in the pin assembly stage, manual operation suffers from inaccurate positioning and inconsistent installation quality, potentially leading to loosening or damage during use.

[0003] To improve the production efficiency and product quality of telescopic ladders, automating the drilling and pin assembly processes has become an urgent problem to be solved. However, existing automated production equipment often suffers from problems such as complex structure, cumbersome operation, and high maintenance costs, making it difficult to meet the actual needs of telescopic ladder manufacturers.

[0022] The following is a detailed description of a drilling and pin assembly mechanism according to the present invention, with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1-4 This invention will be described in detail below.

[0024] A drilling and pin assembly mechanism includes a fixed frame plate 1, a drilling assembly 2, and a pin assembly assembly 3. The fixed frame plate 1 serves as a support platform for the entire mechanism and is equipped with a fixed seat 4 for positioning and fixing the telescopic ladder frame to be processed.

[0025] The drilling assembly 2 includes a drilling cylinder 5 and an electric drill 6. The drilling cylinder 5 is fixed on the fixed frame plate 1, and the electric drill 6 is connected to the power output end of the drilling cylinder 5. Driven by the drilling cylinder 5, the electric drill 6 can move towards the fixed base 4 to precisely drill holes in the telescopic ladder frame.

[0026] The pin assembly 3 includes a feeding component 7 and a pin-feeding component 8. The feeding component 7 is located on one side of the fixed frame plate 1 and is responsible for orderly feeding the pins to the pin-feeding component 8. The pin-feeding component 8 is located below the fixed frame plate 1, and is able to receive the pins from the feeding component 7 and move upward along the fixed frame plate 1 to the fixed seat 4. At the appropriate time, the pin-feeding component 8 drives the pins into the pre-drilled holes in the telescopic ladder frame, completing the pin assembly.

[0027] Furthermore, the power output end of the drilling cylinder 5 of this invention is provided with a push plate 9, and the electric drill 6 is fixed on the top of the push plate 9. This design ensures that the electric drill 6 can move stably and accurately to the drilling position under the drive of the drilling cylinder 5.

[0028] The feeding component 7 includes a direction adjustment cylinder 10, a cylinder rotation frame 11, a material channel fastener 12, and a pin guide plate 13. The direction adjustment cylinder 10 is rotatably connected to the pin guide plate 13 via the cylinder rotation frame 11, allowing adjustment of the angle of the pin guide plate 13 to ensure that the pins can smoothly enter the upper pin component 8. The pin guide plate 13 is rotatably connected to the edge of the fixed frame plate 1 via the material channel fastener 12, facilitating adjustment and maintenance.

[0029] The upper nailing component 8 includes an extension frame plate 14, a pin pushing cylinder 15, a pin feed channel 16, a pin guide sleeve 17, and a pusher 18. The extension frame plate 14 is fixed to the bottom of the fixed frame plate 1, providing support for the pin pushing cylinder 15. The pin pushing cylinder 15 is fixed to the extension frame plate 14, and its end is connected to the pin guide sleeve 17. The pin feed channel 16 is fixed to one side of the top of the pin guide sleeve 17, used to guide the pin into the pin guide sleeve 17. The pusher 18 is located on one side of the pin guide sleeve 17, and under the push of the pin pushing cylinder 15, pushes the pin along the pin guide sleeve 17 to drive it into the telescopic ladder frame.

[0030] In addition, the top of the fixed base 4 is provided with a telescopic ladder slot 19 for positioning and fixing the telescopic ladder frame. The rear of the fixed base 4 is provided with a limiting baffle 20, which extends upward to block the rear end of the telescopic ladder slot 19, thereby limiting the telescopic ladder frame and preventing it from shifting or slipping during processing.

[0031] The specific implementation process of the drilling and pin assembly mechanism of this utility model is as follows:

[0032] Workers place the telescopic ladder material on the telescopic ladder slot 19 of the fixed base 4, and position and limit it using the limiting baffle 20.

[0033] Start the electric drill 6 and drilling cylinder 5 of the drilling assembly 2. The drilling cylinder 5 pushes the electric drill 6 forward to drill a hole in the side wall of the telescopic ladder. After drilling is completed, the electric drill 6 stops running and the drilling cylinder 5 drives the electric drill 6 back to the initial position.

[0034] The pin assembly assembly 3 is activated. The directional adjustment cylinder 10 drives the cylinder transmission frame to rotate, thereby aligning the pin outlet at the lower end of the pin guide plate 13 with the pin channel 16, causing the pins to fall into the pin channel 16. After the pins are filled, the directional adjustment cylinder 10 resets the pin guide plate 13. The pin pushing cylinder 15 is activated, pushing the pin channel 16 upwards to the drilling location on the telescopic ladder. The drilling cylinder 5 is activated, pushing the pushing plate 9 forward, which in turn pushes the extrusion handle 18 on the pin guide sleeve 17, pushing the pins into the drilled holes in the telescopic ladder, thus assembling the telescopic ladder. After assembly, the drilling cylinder 5 and the pin pushing cylinder 15 respectively reset their connected structures. The telescopic ladder assembly is complete, and the workers remove it.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
