Description

Technical Field

[0001] This utility model relates to the field of electric cylinder technology for sliding tables, specifically a gear traveling mechanism for a steel bar riveting press. Background Technology

[0002] Prior to this, we applied for a technical solution for a sliding table module steel channel pressing machine with publication number CN118003059A. In the published patent technology content, the driving structure of the first drive module and the second drive module adopts the screw transmission method.

[0003] Lead screw drives rely on the threaded connection between the lead screw and the nut to achieve linear motion. During operation, the friction between the lead screw and the nut is relatively high, and the helix angle of the thread limits its transmission efficiency. This results in a relatively slow speed at which the lead screw drive structure moves the object, reducing processing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gear-driven walking mechanism for a steel bar riveting press, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gear-driven mechanism for a steel bar riveting machine, comprising a base plate, a first drive module mounted on the upper part of the base plate, a second drive module mounted on the drive end of the first drive module, and a third drive module mounted on the drive end of the second drive module. The first drive module includes a toothed plate mounted on the top of the base plate, teeth formed on the side of the toothed plate, a movable seat slidably mounted on the upper part of the toothed plate, a drive motor mounted on the upper part of the movable seat, and a gear mounted on the drive end of the drive motor extending below the movable seat, with the gear meshing with the teeth.

[0006] Furthermore, the first drive module, the second drive module, and the third drive module enable the riveting rollers of the steel bar riveting machine to move in the X, Y, and Z directions, respectively, and the first drive module and the second drive module have the same structure.

[0007] Furthermore, guide rails are installed on the upper part of the base plate and on both sides of the toothed plate, and sliders are slidably connected to the upper part of the guide rails. The sliders are connected to the bottom end of the movable seat.

[0008] Furthermore, the first drive module, the second drive module, and the third drive module each include a baffle and several photoelectric sensors. The photoelectric sensors are all mounted on the surface of the non-moving parts, and the baffle is mounted on the surface of the moving parts.

[0009] Furthermore, the bottom end of the baffle is integrally connected to a gear shift protrusion, which passes by the photoelectric sensor during the movement of the baffle.

[0010] Furthermore, the drive motor is a servo motor and has a self-locking function.

[0011] This utility model provides a gear-driven mechanism for a steel bar riveting machine. Compared with the prior art, it has the following advantages:

[0012] The gear-driven mechanism of this steel bar riveting machine eliminates the screw drive structure and replaces it with a gear drive structure. This effectively avoids the problem of slow movement speed caused by the large friction between the screw and nut and the thread helix angle limiting the transmission efficiency. It significantly improves the movement speed of the riveting wheel of the steel bar riveting machine, thereby greatly improving the processing efficiency and meeting the needs of modern large-scale and high-efficiency production.

[0019] 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.

[0020] Please see Figure 1-5This utility model provides a technical solution: a gear-driven walking mechanism for a steel bar riveting machine, mainly composed of a base plate 1, a first drive module 2, a second drive module 3, and a third drive module 4. The first drive module 2 is installed on the upper part of the base plate 1, the second drive module 3 is installed at the drive end of the first drive module 2, and the third drive module 4 is installed at the drive end of the second drive module 3. That is, the first drive module 2 can drive the second drive module 3, the third drive module 4, and the riveting wheel of the steel bar riveting machine to move along the X-axis; the second drive module 3 can drive the third drive module 4 and the riveting wheel of the steel bar riveting machine to move along the Y-axis; and the third drive module 4 can drive the riveting wheel of the steel bar riveting machine to move along the Z-axis. The first drive module 2 and the second drive module 3 have the same structure and are driven by gears and teeth meshing, while the third drive module 4 is driven by a screw drive.

[0021] The first drive module 2 includes a toothed plate 21 mounted on the top of the base plate 1 and guide rails 26 symmetrically arranged on both sides of the toothed plate 21. The toothed plate 21 has teeth 22 on its side. The upper part of the guide rail 26 is slidably connected to a slider 27. The upper part of the slider 27 is connected to a movable seat 23. The upper part of the movable seat 23 is equipped with a drive motor 24. The drive motor 24 is a servo motor that can switch between forward and reverse rotation and has a self-locking function. The drive end of the drive motor 24 extends to the bottom of the movable seat 23 and is equipped with a gear 25. The gear 25 meshes with the teeth 22.

[0022] When the first drive module 2 is working, the drive motor 24 drives the gear 25 to rotate. Since the gear 25 meshes with the teeth 22 and the tooth plate 21 is fixed on the base plate 1, under the reaction force, the movable seat 23, drive motor 24, gear 25 and slider 27 as a whole will move along the direction of the guide rail 26.

[0023] In addition, the first drive module 2, the second drive module 3, and the third drive module 4 all include a baffle 28 and several photoelectric sensors 29. The photoelectric sensors 29 are all mounted on the surface of the non-moving parts, and the baffle 28 is mounted on the surface of the moving parts. Taking the first drive module 2 as an example, the photoelectric sensors 29 are mounted on the base plate 1 and distributed along the moving path of the first drive module 2, while the baffle 28 is mounted on the movable seat 23. In this way, when the movable seat 23 moves, it will move synchronously with the baffle 28. The bottom end of the baffle 28 is integrally connected to the stop boss 281. When the baffle 28 moves, the stop boss 281 will pass through the photoelectric sensor 29. The photoelectric sensor 29 is divided into a transmitter and a receiver, and an optical path will be formed between the two. When the stop boss 281 passes between the transmitter and the receiver, the optical path is blocked, which means that the first drive module 2 has reached its position and the drive motor 24 needs to be stopped. This is existing known technology and will not be described in detail here.
