Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, specifically a tapping machine for tapping operations. Background Technology

[0002] Tapping, also known as thread tapping, is a machining method that uses a tap to create internal threads on a workpiece. It is widely used in industries such as machinery manufacturing, automobiles, aerospace, and electronics. It is an indispensable machining process for connecting and assembling parts, and the tapping machine is the core equipment for this process.

[0003] Existing tapping machines generally employ a fixed lever arm transmission structure when machining materials of varying hardness, failing to adaptively adjust torque output based on material properties. This results in excessive load on the servo motor when machining hard materials, increasing energy consumption and increasing the risk of motor damage due to overload. Conversely, it leads to power waste when machining soft materials, thus limiting overall machining efficiency and equipment lifespan. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a tapping machine for tapping, which solves the problem mentioned in the background art that existing tapping machines generally use a fixed lever arm transmission structure when processing materials of different hardness, which cannot adaptively adjust the torque output according to the material characteristics, resulting in excessive load on the servo motor when processing hard materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tapping machine for tapping, comprising an outer frame and two rotating disks, the two rotating disks being of the same size, located on the same vertical line and parallel to each other, and each of the two rotating disks having three adjustment grooves arranged in a circumferential array on its surface, a sliding rod fixedly connected to the inner side of the adjustment groove, a slider being slidably connected to the surface of the sliding rod through and laterally, and a synchronization rod being fixedly connected between the upper and lower sliders.

[0006] In this technical solution, transmission is achieved by setting up two rotating disks, with an adjustable lateral synchronous rod between the disks. This changes the lever arm length and adjusts the transmission torque, reducing the load on the servo motor and significantly improving the durability of the equipment while ensuring processing accuracy.

[0007] Preferably, an electric actuator is fixedly connected to the top of the outer frame, the telescopic end of the electric actuator passes through the top of the outer frame and is fixedly connected to the top plate, and the left and right surfaces of the top plate are both penetrated by limiting rods, the left and right limiting rods are fixedly connected between the upper and lower inner walls of the outer frame, and the limiting rods are slidably connected to the top plate.

[0008] Preferably, a mounting bracket is fixedly connected to the bottom of the top plate, and a servo motor is fixedly connected to the inner horizontal surface of the mounting bracket. The tail end of the drive shaft of the servo motor is connected to the center of the top of the rotating disk above via a coupling.

[0009] Preferably, a rotating rod is rotatably connected between the upper and lower rotating disks. The bottom end of the rotating rod passes through the surface of the lower rotating disk and is fixedly connected to the handle. A threaded section is formed on the surface of the rotating rod above the handle, and a nut is threadedly connected to it. The nut is in contact with the upper rotating disk.

[0010] Preferably, two actuating plates of different sizes are fixedly connected to the surface of the rotating rod between the two rotating disks, and the actuating plates are parallel to the rotating disks.

[0011] Preferably, a base frame is fixedly connected to the bottom of the rotating disk located below, and a tapping head is provided at the center of the bottom of the base frame.

[0013] 1. This utility model implements transmission by setting two rotating disks, and a synchronizing rod with an adjustable lateral position is provided between the transmission disks, thereby changing the lever arm length and adjusting the transmission torque, reducing the load on the servo motor, and significantly improving the durability of the equipment while ensuring processing accuracy.

[0014] 2. This utility model sets a rotating rod between two rotating disks, and a toggle plate that rotates with the rotating rod is set on the surface of the rotating rod.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] A tapping machine for thread tapping, see [link / reference] Figures 1 to 4 The system includes an outer frame 1 and two rotating disks 6. The two rotating disks 6 are of the same size, located on the same vertical line and parallel to each other. Each rotating disk 6 has three adjustment slots 601 arranged in a circular array on its surface. A sliding rod 602 is fixedly connected to the inner side of the adjustment slot 601. A slider 603 is slidably connected to the surface of the sliding rod 602 through it. A spring is sleeved on the surface of the sliding rod 602 between the slider 603 and the inner wall of the adjustment slot 601. The spring is located on the side away from the center of the rotating disk 6. A synchronizing element is fixedly connected between the upper and lower sliders 603. The two rotating disks 6 are kept in sync by the synchronizing rod 7. The servo motor 5 directly drives the upper rotating disk 6 to rotate, and the upper rotating disk 6 drives the lower rotating disk 6 and the bottom tapping assembly to rotate through the synchronizing rod 7. The synchronizing rod 7 can move laterally along the adjusting groove 601, thereby changing its distance from the center of the rotating disk 6. The farther away from the center, the longer the lever arm, making it easier to drive the lower rotating disk 6 and the tapping assembly to rotate. This reduces the effort required when processing materials of different hardness and reduces the pressure on the servo motor 5.

[0023] It should be noted that, to ensure the safe and stable operation of the equipment, the synchronizing rod 7 can be made of alloy structural steel that has undergone quenching and tempering treatment. This steel has high tensile strength and impact absorption capacity, effectively resisting torque impacts during high-speed rotation. The rod surface is further coated with a molybdenum disulfide wear-resistant coating to reduce the coefficient of friction with the slider 603, ensuring stable transmission even under high-speed rotation conditions and preventing deformation or breakage due to material fatigue.

[0024] Specifically, such as Figure 3 and Figure 4As shown, a rotating rod 10 is rotatably connected between the upper and lower rotating disks 6. The bottom end of the rotating rod 10 passes through the surface of the lower rotating disk 6 and is fixedly connected to the handle 11. The rotating rod 10 is rotatably connected to the lower rotating disk 6. Two actuating plates 1002 of different sizes are fixedly connected to the surface of the rotating rod 10 between the two rotating disks 6. The actuating plates 1002 are parallel to the rotating disks 6. When it is necessary to change the position of the synchronizing rod 7, the rotating rod 10 rotates, and the actuating plates 1002 rotate with the rotating rod 10. During the rotation, the synchronizing rod 7 is pushed to move laterally, thereby changing the position of the synchronizing rod 7, which is convenient and quick.

[0025] It is worth noting that, such as Figure 3 As shown, the rotating rod 10 above the handle 11 has a threaded section on its surface and is threadedly connected to a nut 1001. The nut 1001 contacts the rotating disk 6 above. When the rotating rod 10 needs to be rotated, simply hold the handle 11 and rotate it. The rotation of the rotating rod 10 itself has a damping effect. After adjusting the position of the synchronizing rod 7, rotating the nut 1001 causes it to move upward and press against the surface of the rotating disk 6, thus keeping the rotating rod 10 stable and the actuating plate 1002 stable.

[0026] Furthermore, such as Figure 1 As shown, an electric push rod 2 is fixedly connected to the top of the outer frame 1. The telescopic end of the electric push rod 2 passes through the top of the outer frame 1 and is fixedly connected to the top plate 3. The left and right surfaces of the top plate 3 are both penetrated by limiting rods 101. The two limiting rods 101 are fixedly connected between the upper and lower inner walls of the outer frame 1, and the limiting rods 101 are slidably connected to the top plate 3. During tapping, the servo motor 5 drives the tapping assembly to rotate, while the electric push rod 2 drives the top plate 3 and the assembly below to descend at a certain speed to perform tapping on the workpiece surface. After the electric push rod 2 is started, the top plate 3 will remain horizontal and descend smoothly under the constraint of the left and right limiting rods 101, thereby ensuring the machining accuracy.

[0027] It is worth noting that, such as Figure 3 As shown, a mounting bracket 4 is fixedly connected to the bottom of the top plate 3. A servo motor 5 is fixedly connected to the inner horizontal surface of the mounting bracket 4. The tail end of the drive shaft of the servo motor 5 is connected to the center of the top of the upper rotating disk 6 through a coupling. A base frame 8 is fixedly connected to the bottom of the lower rotating disk 6. A tapping head 9 is provided at the center of the bottom of the base frame 8. The tapping head 9 can be set with different models and sizes according to the actual processing conditions to meet the processing requirements.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
