Description

Technical Field

[0001] This invention relates to the field of intelligent machine tool technology, specifically to an intelligent machine tool equipped with a transverse movement mechanism. Background Technology

[0002] Intelligent machine tools play a crucial role in modern automated manufacturing, particularly in improving processing efficiency, operational stability, and production flexibility. These machine tools, through precise lateral movement design, achieve accurate positioning and efficient transfer of workpieces or processing units, and are widely used in high-end manufacturing fields such as aerospace, rail transportation, and new energy vehicles.

[0003] However, the existing technology has the following problems: the traditional machine head installation method usually relies on a special mounting plate to connect the machine head and the mold moving assembly. This method not only requires secondary machining of the mounting back plate during the assembly process, which leads to a complicated process and extended assembly cycle, but also introduces additional components and connection interfaces, increasing the complexity of the overall structure and cumulative errors. To address these issues, we propose an intelligent machine tool with a transverse movement mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent machine tool with a transverse movement mechanism to solve the problems mentioned in the background art. Traditional machine head installation not only requires secondary machining of the mounting back plate during the assembly process, resulting in a cumbersome process flow and extended assembly cycle, but also introduces additional components and connection interfaces, increasing the complexity of the overall structure and the accumulation of errors.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent machine tool with a transverse movement mechanism, comprising an up-down transverse movement mechanism, a left-right transverse movement mechanism, a left-right micro-movement mechanism, and a pressure mold, wherein the left-right transverse movement mechanism is mounted on the outer side of the up-down transverse movement mechanism, the left-right micro-movement mechanism is mounted on the outer side of the left-right transverse movement mechanism, and a pressure mold is provided on the top of the left-right micro-movement mechanism;

[0006] The vertical lateral movement mechanism consists of a servo motor, a ball screw, a connecting plate, and a mounting back plate.

[0007] The left and right transverse movement mechanism consists of a servo motor, a ball screw, a fixed frame, a first slider, and a first slide rail.

[0008] The left and right micro-movement mechanism consists of a servo motor, a reducer, gears, a fixed plate, and a rack.

[0009] The pressure mold consists of a T-slot, a top mounting plate, and a positioning plate.

[0010] Preferably, a ball screw is installed at the top output end of the servo motor, a connecting plate is movably connected to the outer side of the ball screw, and a mounting back plate is fixedly connected to the surface of the connecting plate.

[0011] Preferably, a second servo motor is fixedly installed at the bottom of the mounting back plate, a second ball screw is connected to the output end of the second servo motor, a fixed frame is connected to the outer side of the second ball screw, two sets of first sliders are fixedly connected to the outer surface of the fixed frame, and two sets of first slide rails are fixedly connected to the surface of the mounting back plate.

[0012] Preferably, a servo motor three is fixedly installed inside the fixed frame, a reducer is installed on the top of the servo motor three, a gear is connected to the output end of the reducer, a fixed plate is provided on the top of the fixed frame, and a rack is fixedly connected to the bottom of the fixed plate, with the rack and gear meshing with each other.

[0013] Preferably, the top of the fixing plate is provided with a T-shaped groove, a top mounting plate is installed inside the T-shaped groove, and a positioning plate is installed on the surface of the top mounting plate.

[0014] Preferably, the bottom sides of the fixing plate are respectively fixedly connected to the second slider, and the surface of the fixing frame is fixedly connected to two sets of second slide rails.

[0015] Preferably, a displacement sensor is installed inside the first slider, a displacement sensor is installed inside the second slide rail, and a pressure sensor is installed inside the positioning plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The core of this invention lies in eliminating the need for a separate dedicated mounting plate, instead directly connecting the mold-moving assembly to the head frame. This design, by eliminating redundant mounting plates and auxiliary connectors, effectively reduces the overall mass and inertial load of moving parts, thus improving the system's dynamic response performance and motion accuracy. Secondly, the direct connection method significantly compresses structural space, making the layout more compact and significantly improving space utilization. Finally, based on the simplification of the overall structure, it achieves miniaturization and lightweight design of the head module, providing a structural foundation for the deployment and performance improvement of the equipment within limited space. This optimization not only simplifies the assembly process but also enhances the rigidity and stability of the structure at the system level.

[0018] 2. This invention employs a combination of self-aligning roller bearings and thrust needle roller bearings. The thrust needle roller bearings are specifically designed to withstand high axial loads, providing excellent axial load-bearing stiffness. The self-aligning roller bearings, on the other hand, bear the main radial loads and, thanks to their inherent self-aligning properties, allow for a certain relative angular displacement between the inner and outer rings, thereby automatically compensating for coaxiality deviations caused by installation errors or shaft deflection. Compared to traditional solutions, this composite bearing system achieves a synergistic effect of high axial stiffness, high radial load capacity, and automatic self-aligning compensation, demonstrating stronger adaptability to harsh working conditions such as heavy loads and off-center loads. This significantly improves the system's operational stability, feed accuracy, and the overall service life of key components.

[0019] 3. This invention utilizes a pressure mold, employing a set screw adjustment mechanism to replace the traditional multi-screw adjustment scheme. This effectively solves the problems of spatial interference and motion coupling between multiple adjustment points, improving adjustment accuracy and efficiency. During mold replacement, the pressure mold can be removed simply by disassembling the top mounting plate and upper positioning block, achieving modular and rapid replacement. This design avoids the impact of repeated disassembly and assembly on the back plate mounting reference surface, ensuring the positioning accuracy of the system for long-term use. Furthermore, the set screws on the back plate ensure that the pressure mold is tightly pressed against the pipe surface during assembly, ensuring a stable contact state between the two during processing, thereby guaranteeing process consistency during forming.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-5 An embodiment of the present invention provides an intelligent machine tool with a transverse movement mechanism, comprising an up-down transverse movement mechanism 1, a left-right transverse movement mechanism 2, a left-right micro-movement mechanism 3, and a pressure mold 4. The left-right transverse movement mechanism 2 is mounted on the outer side of the up-down transverse movement mechanism 1, and the left-right micro-movement mechanism 3 is mounted on the outer side of the left-right transverse movement mechanism 2. The pressure mold 4 is located on the top of the left-right micro-movement mechanism 3. The up-down transverse movement mechanism 1 is composed of a servo motor 101, a ball screw 102, a connecting plate 103, and a mounting back plate 104. The left-right transverse movement mechanism 2 is composed of a servo motor 201, a ball screw 202, a fixing frame 203, a first slider 204, and a first slide rail 205. The left-right micro-movement mechanism 3 is composed of a servo motor 301, a reducer 302, a gear 303, a fixing plate 304, and a rack 305. The pressure mold 4 is composed of a T-slot 401, a top mounting plate 402, and a positioning plate 403.

[0029] This device, through the setup of the vertical horizontal movement mechanism 1, the horizontal horizontal movement mechanism 2, the horizontal micro-movement mechanism 3, and the pressure mold 4, solves the problems of traditional machine head installation, which not only requires secondary machining of the mounting back plate during the assembly process, leading to a cumbersome process flow and extended assembly cycle, but also introduces additional components and connection interfaces, increasing the complexity of the overall structure and the accumulation of errors.

[0030] Furthermore, a ball screw 102 is mounted on the top output end of the servo motor 101, and a connecting plate 103 is movably connected to the outer side of the ball screw 102. A mounting back plate 104 is fixedly connected to the surface of the connecting plate 103. Figure 2As shown, this structure is used to move and adjust the mounting back plate 104 up and down by starting the servo motor 101 to drive the connecting plate 103 at the ball screw 102.

[0031] Furthermore, a servo motor 201 is fixedly mounted on the bottom of the mounting backplate 104. The output end of the servo motor 201 is connected to a ball screw 202. A fixing bracket 203 is connected to the outer side of the ball screw 202. Two sets of first sliders 204 are fixedly connected to the outer surface of the fixing bracket 203. Two sets of first slide rails 205 are fixedly connected to the surface of the mounting backplate 104. Figure 3 As shown, this structure is used to drive the ball screw 202 by starting the servo motor 201, so that the fixed frame 203 can move left and right along the first slide rail 205 with the help of the first slider 204.

[0032] Furthermore, a servo motor 301 is fixedly installed inside the mounting bracket 203. A reducer 302 is mounted on the top of the servo motor 301. A gear 303 is connected to the output end of the reducer 302. A mounting plate 304 is provided on the top of the mounting bracket 203. A rack 305 is fixedly connected to the bottom of the mounting plate 304. The rack 305 and the gear 303 mesh with each other. Figure 4 As shown, this structure is used to drive the gear 303 to rotate by starting the servo motor 301 with the assistance of the reducer 302. Through the meshing of the gear 303 and the rack 305, the fixed plate 304 can be finely adjusted left and right.

[0033] Furthermore, a T-slot 401 is provided on the top of the fixing plate 304. A top mounting plate 402 is installed inside the T-slot 401, and a positioning plate 403 is installed on the surface of the top mounting plate 402. This structure uses a T-slot 401, a top mounting plate 402, and double positioning blocks for installation. The top mounting plate 402 and the positioning plate 403 are equipped with set screws, allowing for adjustment of their position and height. During mold replacement, only the top mounting plate 402 and the positioning plate 403 need to be disassembled to remove the pressure mold 4, achieving modular and rapid replacement. This design avoids the impact of repeated disassembly and assembly on the mounting reference surface, ensuring the positioning accuracy of the system for long-term use. In addition, the set screws on the top mounting plate 402 can tightly press the positioning plate 403 against the pipe surface during assembly, ensuring a stable contact state between the two during processing, thereby guaranteeing process consistency during forming. Figure 5 As shown, this structure is used to move the pressure mold 4 linearly to the set position and clamp the pipe by adjusting the up-down horizontal movement mechanism 1, the left-right horizontal movement mechanism 2 and the left-right micro-movement mechanism 3. The pressure mold 4 moves along the arc length of the rotating mold to complete the pipe bending action.

[0034] Furthermore, second sliders 307 are fixedly connected to the bottom of both sides of the fixed plate 304, and two sets of second slide rails 306 are fixedly connected to the surface of the fixed frame 203. Figure 4 As shown, this structure is used to move left and right along the second slide rail 306 with the help of the second slider 307 when the fixed plate 304 moves, thereby improving the stability and accuracy of the device.

[0035] Furthermore, a displacement sensor 206 is installed inside the first slider 204, a displacement sensor 308 is installed inside the second slide rail 306, and a pressure sensor 404 is installed inside the positioning plate 403. Figure 2 and Figure 5 As shown, this structure is used to collect the position signal of the actuator in real time through displacement sensor 206 and feed it back to the driver. Together with the encoder signals built into servo motor 101 and servo motor 201, it forms a fully closed-loop control circuit. This control architecture realizes real-time monitoring and dynamic compensation of the machine head's motion trajectory, thereby ensuring the system's high precision, high responsiveness, and operational stability. At the same time, side displacement sensor 308 collects the linear displacement data of the left and right micro-movement mechanism 3 and pressure mold 4 in real time and feeds it back to the driver, forming a fully closed-loop control. Pressure sensor 404 is installed at the positioning plate 403 to monitor the contact pressure between the mold and the pipe during the positioning plate 403's mold-fitting process in real time and feeds back the pressure data to the driver, realizing real-time monitoring and adjustment of the bending pressure. Throughout the entire process, precise control of the mold-fitting, follow-up, and reset processes is achieved through the coordinated data of multiple sensors, including displacement, pressure, and angle.

[0036] Working principle: When using, such as Figure 2 and Figure 3As shown, servo motor 201 serves as the power source, outputting rotational torque and directly connected to ball screw 102, converting rotational motion into precise linear displacement. This drives connecting plate 103 to adjust the mounting back plate 104 vertically. Simultaneously, servo motor 301, assisted by reducer 302, drives gear 303 to rotate. Through the meshing of gear 303 and rack 305, fixed plate 304 is finely adjusted left and right. Displacement sensor 206 collects the position signal of the actuator in real time and feeds it back to the driver. Together with the encoder signals built into servo motor 101 and servo motor 201, they form a closed-loop control circuit for real-time monitoring and dynamic compensation of the machine head's motion trajectory, and activate the servo motor... With the assistance of reducer 302, motor 301 drives gear 303 to rotate. Through the meshing of gear 303 and rack 305, fixed plate 304 is finely adjusted left and right. Side displacement sensor 308 collects the linear displacement data of left and right micro-movement mechanism 3 and pressure mold 4 in real time and feeds it back to driver to form a closed-loop control. After the pressure mold 4 is linearly moved to the set position, it clamps the pipe. The pressure mold 4 moves along the arc length of the rotating mold to complete the pipe bending action. Pressure sensor 404 is installed at the positioning plate 403 to monitor the contact pressure between the mold and the pipe in real time during the positioning plate 403 approaching the mold and feeds back the pressure data to driver to realize real-time monitoring and adjustment of bending pressure. The above is the complete working principle of the present invention.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
