AI Technical Summary
Existing mechatronics cutting devices are prone to deformation of the cut when cutting pipes, especially when the pipe diameter is small, the wall thickness is thin, or the material is easily deformable, due to stress concentration. Furthermore, when there are requirements for the cutting angle, the pipe needs to be flipped, which leads to alignment errors.
An electromechanical integrated cutting device was designed, which uses two cutting machines to cut from both sides of the pipe respectively. The cutting machines are moved in the same plane by a drive mechanism. Combined with support and fixing components, the stress is concentrated in the middle of the support during the cutting process to avoid deformation, and the pipe does not need to be flipped.
It improves the flatness of the cut when cutting thin-walled or easily deformable pipes, reduces labor intensity, avoids deformation caused by stress concentration, and can automatically adjust the cutting angle.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cutting devices, and in particular relates to an electromechanical integrated cutting device. Background Technology
[0002] Mechatronics, also known as mechanical and electronic engineering, is a branch of mechanical engineering and automation. With the rapid development and widespread application of computer technology, mechatronics technology has experienced unprecedented growth. Mechatronics is an independent interdisciplinary field that integrates computer technology, information technology, mechanical technology, electronic technology, control technology, and optical technology. Modern automated production equipment can almost all be considered mechatronic devices. Mechatronic cutting devices are intelligent cutting systems that deeply integrate mechanical, electronic, and computer control technologies. They can efficiently and accurately complete material processing tasks. Their core lies in the coordinated work of sensors, actuators, controllers, and software to achieve automation, intelligence, and high precision in the cutting process.
[0003] Current mechatronic cutting devices typically cut pipes continuously in one manner until the pipe is completely cut into two parts. However, when the pipe diameter is small, the wall thickness is thin, or the material is easily deformable, the cut is prone to deformation due to stress concentration, especially when the cut is about to be completed or when there are requirements for the cutting angle. Therefore, there is a need for a device that can cut from one side to the middle of the pipe first, and then complete the cut from the other side. In this way, the stress concentration at the end of the cut is less likely to cause deformation in the supported middle section. Although this operation can be achieved by flipping the pipe, this method requires two positioning, which may lead to alignment errors, especially when the pipe is long and heavy, and when there are requirements for the cutting angle. Utility Model Content
[0004] The purpose of this invention is to provide an electromechanical integrated cutting device that can prevent deformation of the cut due to stress concentration.
[0005] The mechatronic cutting device includes a base plate and a mounting frame fixed to the top of the base plate. A pipe is arranged above the base plate. Two support components are fixed to the top of the base plate, arranged front to back, for supporting the pipe. Each support component is provided with a retaining component above it for pressing the pipe against the support component. A first cutting machine and a second cutting machine are respectively arranged on the left and right sides of the pipe, and the cutting blades of the first cutting machine and the second cutting machine are located in the same plane. A drive mechanism is installed on the inner top of the mounting frame, which is rotatably engaged with it and is used to drive the first cutting machine and the second cutting machine to move independently.
[0006] Furthermore, the mounting frame includes a top plate, which is fixed to the top plate by four rectangularly distributed support plates.
[0007] Furthermore, the support assembly includes a fixed base, the top of which has a groove, and a roller that is rotatably engaged with the groove is installed in the groove.
[0008] Furthermore, the diameter of the roller increases sequentially from the middle to both sides.
[0009] Furthermore, the retaining assembly includes a connecting plate, a retaining block is disposed below the connecting plate, and an electric push rod for driving the retaining block to move up and down is installed at the bottom of the connecting plate.
[0010] Furthermore, the clamping block has a Greek letter "Λ" shaped structure.
[0011] Furthermore, the driving mechanism includes a downward-opening mounting groove. A first driving rod and a second driving rod are horizontally arranged in the mounting groove, distributed front-to-back and parallel to each other. A first driving motor is mounted at one end of each of the first and second driving rods. The left half of the first driving rod is threaded, and the right half of the second driving rod is threaded. A slider is fixed to the top of both the first and second cutting machines. The slider on the top of the first cutting machine is threadedly engaged with the left half of the first driving rod and slidably engaged with the left half of the second driving rod. The slider on the top of the second cutting machine is slidably engaged with the right half of the first driving rod and threadedly engaged with the right half of the second driving rod. The mounting groove is mounted on the bottom of a top plate via a toothed turntable bearing. An adjustment assembly for adjusting the rotation angle of the mounting groove is mounted on the top plate.
[0012] Furthermore, the adjustment assembly includes a gear located on one side of the turntable bearing and meshing with it, and a second drive motor for driving the gear to rotate is mounted on the top of the top plate.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In this embodiment, the drive assembly enables both the first and second cutting machines to move independently, allowing them to cut the pipe from the left and right sides respectively. This ensures that the stress during the final cut is released in the supported middle section of the pipe, preventing deformation caused by stress concentration at the unsupported edges when cutting pipes with small diameters, thin walls, or easily deformable materials. Furthermore, since the cutting blades of the first and second cutting machines are in the same plane, the flatness of the cuts formed by the two cuts is improved, and the cutting can be completed without the need for manual flipping of the pipe, effectively reducing labor intensity.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example 1
[0021] The mechatronics cutting device described in this embodiment includes a base plate 1 and a mounting bracket fixed to the top of the base plate 1, such as... Figure 1 and Figure 2 As shown, the mounting frame includes a top plate 12, which is fixed to the bottom plate 1 by four rectangularly distributed support plates 14.
[0022] A pipe fitting 4 is installed above the base plate 1. Two fixed seats 2, arranged front to back, are fixed to the top of the base plate 1. The top of each fixed seat 2 has a groove, within which a roller 3 is installed in a rotatable engagement. (The fixed seats 2 and rollers 3 together constitute the support assembly for supporting the pipe fitting 4; the roller 3 can also be an arc-shaped plate with a downward-curving center.) In this embodiment, the two rollers 3 support the front and rear ends of the pipe fitting 4 at the cutting point, thus ensuring the stability of the cutting. Furthermore, both rollers 3 can rotate, effectively reducing the labor intensity of workers pushing the pipe fitting 4. Figure 1 and Figure 2 As shown, the roller 3 is mounted on the groove wall of the groove at both ends via shafts and bearings. The groove has no front and back walls. The diameter of the roller 3 increases from the middle to both sides. This structure, which is small in the middle and large on both sides, can play an automatic positioning role, so that the pipe 4 always moves in a straight line. Therefore, without the need for manual positioning by workers, the cutting angle of each section of pipe 4 after cutting can remain unchanged without special requirements.
[0023] Each support assembly has a connecting plate 13 above it, and a clamping block 6 below it. An electric push rod 7 is installed at the bottom of the connecting plate 13 to drive the clamping block 6 to move up and down. (The connecting plate 13, clamping block 6, and electric push rod 7 together constitute the retaining assembly for clamping the pipe fitting 4 against the support assembly; the electric push rod 7 can also be a cylinder or a hydraulic cylinder.) In this embodiment, the electric push rod 7 drives the clamping block 6 to move downwards to clamp the pipe fitting 4 against the two rollers 3, thereby further improving the stability of the pipe fitting 4 during cutting. Figure 1 As shown, the connecting plate 13 is fixed between the two support plates 14 on the rear side or the two support plates 14 on the front side. The electric push rod 7 is existing technology. It consists of a drive motor, reduction gear, screw, nut, guide sleeve, push rod, slide, spring, housing, turbine, micro-motion control switch, etc. It is an electric drive device that converts the rotational motion of the electric motor into the linear reciprocating motion of the push rod. The housing of the electric push rod 7 is fixed to the bottom of the connecting plate 13, and the push rod power output end of the electric push rod 7 is fixed to the top of the abutment block 6.
[0024] A first cutting machine 15 and a second cutting machine 5 are respectively installed on the left and right sides of the pipe fitting 4, and the cutting blades of the first cutting machine 15 and the second cutting machine 5 are located in the same plane, such as... Figure 1 and Figure 2 As shown, in this embodiment, the first cutting machine 15 and the second cutting machine 5 can cut the pipe 4 from the left and right sides respectively, so that the stress at the final cut is released in the supported middle section of the pipe 4. This avoids deformation caused by stress concentration at the unsupported edge of the pipe 4 when cutting pipes with small diameter, thin wall thickness or easily deformable materials. At the same time, since the cutting blades of the first cutting machine 15 and the second cutting machine 5 are in the same plane, the flatness of the cut formed by the two cuts can be improved, and the cutting can be completed without the need for workers to manually flip the pipe 4, which effectively reduces the labor intensity. The first cutting machine 15 and the second cutting machine 5 are both composed of a connecting wall, a machine head with a motor and a cutting blade, such as an angle grinder.
[0025] refer to Figure 1 , Figure 2 and Figure 3A downward-facing mounting groove 9 is provided below the base plate 12. A first drive rod 11 and a second drive rod 16, horizontally arranged front-to-back and parallel to each other, are positioned within the mounting groove 9. A first drive motor is mounted at one end of both the first drive rod 11 and the second drive rod 16. The left half of the first drive rod 11 and the right half of the second drive rod 16 are threaded. A slider 8 is fixed to the top of both the first cutting machine 15 and the second cutting machine 5. The slider 8 on the top of the first cutting machine 15 is threaded into the left half of the first drive rod 11 and slidably engaged with the left half of the second drive rod 16. The slider 8 on the top of the second cutting machine 5 is slidably engaged with the right half of the first drive rod 11 and threadedly engaged with the right half of the second drive rod 16. The mounting groove 9 is mounted on the bottom of the base plate 12 via a toothed turntable bearing 10. A gear meshing with the turntable bearing 10 is provided on one side of the turntable bearing 10. A second drive motor for driving the gear rotation is mounted on the top of the base plate 12. (The mounting groove 9 mentioned in this paragraph...) The first drive rod 11, the second drive rod 16, the first drive motor, the slider 8, the turntable bearing 10, the gear, and the second drive motor together constitute the drive mechanism for driving the first cutter 15 and the second cutter 5 to move independently. The gear and the second drive motor together constitute the adjustment component for adjusting the rotation angle of the mounting slot 9. In practical applications, both the first drive motor and the second drive motor can be stepper motors or servo motors. In this embodiment, the two first drive motors respectively drive the connected first drive rod 11 and the second drive rod 16 to rotate. Since the threaded sections of the first drive rod 11 and the second drive rod 16 are in opposite positions, the two sliders 8 can move independently left and right, thereby driving the first cutter 15 and the second cutter 5 to cut the pipe 4 independently. Simultaneously, the second drive motor drives the gear to rotate, which in turn drives the toothed turntable bearing 10 to rotate, thereby rotating the mounting slot 9 by a certain angle, thus achieving the effect of freely changing the cutting angle. Figure 4 As shown;
[0026] like Figure 1 and Figure 2 As shown, the connecting arms of the first cutting machine 15 and the second cutting machine 5 are respectively fixed to the bottom of the left slider 8 and the right slider 8. The turntable bearing 10 is a prior art technology, also called a slewing bearing. It is a large bearing with a special structure that can simultaneously withstand large axial loads, radial loads and overturning moments, and integrates multiple functions such as support, rotation, transmission and fixation. It is usually composed of four major components: inner ring, outer ring, rolling elements and spacer blocks. Its function is to connect the upper and lower parts of the machine together, support the weight of the upper part and the load generated when the machine is working, and make the upper part of the machine rotate relative to the lower part (or the lower part rotate relative to the upper part). In this embodiment, the lower part is toothed and fixed to the top of the mounting groove 9, while the upper part of the turntable bearing 10 is fixed to the base plate 12 and is a stationary part.
[0027] In practical application, the support plate 14 is also equipped with a central control screen. The central control screen is used to control the extension of the electric push rod 7 to achieve the clamping of pipes 4 with different diameters. The feed amount of the first cutting machine 15 and the second cutting machine 5 is controlled by controlling the start time of the first drive motor. The cutting angle is controlled by controlling the number of rotations of the drive gear of the second drive motor. Of course, an encoder or angle sensor can also be installed to monitor the rotation angle.
[0028] In this embodiment, the cutting section of the pipe fitting 4 is first placed between the two rollers 3. Then, the electric push rod 7 is extended to press the pipe fitting 4 against the rollers 3. Next, the two first drive motors are started respectively, so that the first cutter 15 and the second cutter 5 complete the cutting operation from one side to the middle section of the pipe fitting 4, and then complete the cutting from the other side. If there is a requirement for the cutting angle, the second drive motor is started to drive the gear to rotate. The rotation of the gear drives the toothed turntable bearing 10 on the outer ring to rotate. In this way, the mounting groove 9 can be rotated at a certain angle, and the cutting angle of the first cutter 15 and the second cutter 5 will change accordingly. Example 2
[0029] This embodiment further illustrates the technology; the clamping block 6 has a Greek letter "Λ" shaped structure, as shown below. Figure 1 As shown, the "Λ"-shaped clamping block 6 not only clamps the pipe 4 against the roller 3, but also limits the pipe 4 from the left and right directions, thereby further ensuring the stability of the pipe 4 during cutting.
