Description

Technical Field

[0001] This invention relates to the field of industrial electromechanical manufacturing technology, specifically to a cutting and welding machine tool for intelligent industrial electromechanical processing. Background Technology

[0002] In the field of industrial electromechanical manufacturing, cutting and welding machine tools are indispensable and crucial equipment, and their technological level directly affects product quality and production efficiency. Advances in cutting and welding machine tool technology contribute to improving industrial production efficiency and product quality, driving the continuous development of the industrial electromechanical processing field. Currently, beveling is required at the ends of the parts to be welded during the welding process, and the efficiency of beveling directly impacts the welding production efficiency.

[0003] Patent CN118456036B discloses an industrial electromechanical manufacturing cutting and welding machine tool. Its working principle is as follows: When the beveling grinding device 5 beveles two workpieces 2, the operator places the two workpieces 2 on either side of the beveling grinding device 5, with the grinding surfaces of the first grinding disc 51 and the second grinding disc 54 facing the two workpieces 2 respectively. The third drive structure 53 drives the second rotating shaft 52 to rotate, which in turn drives the first grinding disc 51 and the second grinding disc 54 to rotate simultaneously. The first grinding disc 51 and the second grinding disc 54 simultaneously grind the two welding end faces of the two workpieces 2. During the grinding process, the fourth drive structure 553 operates, and the second bidirectional screw... The rotation of rod 5532 causes the two second moving blocks 5533 to move away from each other. The second spring 554 releases some elastic potential energy and pushes the first grinding disc 51 and the second grinding disc 54 to move toward the two ends of the second rotating shaft 52 respectively, thereby increasing the distance between the first grinding disc 51 and the second grinding disc 54. When the first grinding disc 51 and the second grinding disc 54 move downward under the action of the adjustment mechanism 7, the outer side of the grinding surface of the first grinding disc 51 and the second grinding disc 54 will contact the workpiece 2, so that the outer side of the grinding surface of the first grinding disc 51 and the second grinding disc 54 participates in the bevel grinding work, thereby achieving uniform wear of the grinding surface of the first grinding disc 51 and the second grinding disc 54.

[0004] Although the above solution enables simultaneous grinding of two workpieces and improves grinding efficiency, the first and second grinding discs will experience severe friction with the workpieces during grinding, causing the first and second grinding discs to vibrate. This, in turn, causes the second spring between the first and second grinding discs to vibrate. As a result, the first and second grinding discs will jump along the axis of the second rotating shaft during the grinding process. The jumping first and second grinding discs not only have poor grinding effect when they come into contact with the workpiece, but also exacerbate the jumping of the first and second grinding discs. Summary of the Invention

By setting up a grinding mechanism, a first lifting mechanism, a fixing mechanism, a lifting plate, a second lifting mechanism, and a linkage structure, the grinding mechanism and two workpieces are linked through the linkage structure, avoiding the jumping phenomenon when the grinding disc contacts the workpiece.

[0008] Preferably, the linkage mechanism further includes two angle adjustment mechanisms, which are disposed on the lifting plate. Each angle adjustment mechanism includes two adjustment plates, two connecting shafts, and a drive assembly. The two adjustment plates correspond to two corresponding linkage plates on both sides of the U-shaped frame, and adjustment grooves are provided on the adjustment plates. The two connecting shafts are slidably disposed in the adjustment grooves and are connected to the linkage plates. The drive assembly is connected to the two adjustment plates in a transmission manner.

[0009] Preferably, the linkage mechanism further includes a synchronous drive structure, which is disposed between the two angle adjustment mechanisms and is connected to the two angle adjustment mechanisms in a transmission manner.

[0010] Preferably, the second lifting mechanism includes a second lead screw, two second moving blocks, and two second drive plates; the second lead screw is horizontally disposed in the middle of the base, and both ends of the second lead screw are connected to the base; the two second moving blocks are respectively disposed at both ends of the second lead screw; the two second drive plates correspond to the two second moving blocks respectively, and both ends of the second drive plates are axially connected to the lifting plate and the second moving block respectively.

[0011] Preferably, the U-shaped frame has a first groove at both ends, and a first guide structure is provided in each of the two first grooves. The two first guide structures are connected to the grinding mechanism.

[0012] Preferably, the grinding device further includes a locking structure, which includes a second guide structure and two locking components; the second guide structure is disposed at the lower end of the grinding mechanism, and the two ends of the second guide structure are respectively facing the two ends of the U-shaped frame; the two locking components are respectively disposed at the two ends of the second guide structure, and the locking components are connected to the second guide structure.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention links cutting, fixing, grinding, and welding processes, improving processing efficiency. Two fixing mechanisms clamp and fix the two workpieces, ensuring a tight fit at the welding ends, providing a stable reference for subsequent grinding and welding operations. The first lifting mechanism and linkage structure drive the two workpieces to move away synchronously, ensuring a consistent distance between the grinding disc and the two workpieces. During grinding, the linkage mechanism drives the grinding device to reciprocate and move horizontally, while simultaneously controlling the mechanism to drive the workpiece to rotate, ensuring that the grinding surface can evenly cover the workpiece surface. The linkage structure links the grinding mechanism and the two workpieces, avoiding the jumping phenomenon when the grinding disc contacts the workpiece, thereby achieving uniform utilization of the grinding disc surface and enhancing processing stability.

[0018] 2. By setting two linkage plates and a linkage shaft, and matching the tilt angle of the linkage plates with the tilt angle of the grinding disc, the present invention achieves a constant ratio between the rising speed of the grinding disc and the speed at which the two workpieces move away from each other. This effectively avoids the increase of the grinding disc intrusion into the workpiece during the lifting process, thereby ensuring the uniformity of grinding and the integrity of the workpiece.

[0019] 3. The present invention includes an adjustment plate, a connecting shaft, and a drive assembly. The drive assembly controls the distance between the two adjustment plates, and then drives the linkage plate to rotate around its shaft connection point with the U-shaped frame through the adjustment plate and the connecting shaft, thereby adjusting the tilt angle of the linkage plate and ensuring that the linkage plate can remain parallel to the grinding surfaces of different grinding discs, thus maintaining an effective linkage relationship between the grinding discs and the workpiece.

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1 to 13 The following is a description of a cutting and welding machine tool for intelligent industrial electromechanical processing: It includes a worktable 1 and a base 2 arranged parallel to each other. A cutting device and a welding device are located at the upper part of the middle of the worktable 1 (not shown in the figure). The machine also includes a grinding device 3, two fixing mechanisms 4, and a linkage mechanism 5. The grinding device 3 includes a grinding mechanism 31 and a first lifting mechanism 32. The grinding mechanism 31 is located in the middle of the worktable 1 and includes a rectangular frame 312, a first rotating shaft 313, a connecting plate 314, and a grinding disc 311. The rectangular frame 312 is located at the lower end of the worktable 1. The first rotating shaft 313 is vertically arranged inside the rectangular frame 312, with one end extending upwards from the rectangular frame 312. The connecting plate 314 is fixedly arranged at one end of the first rotating shaft 313. The grinding disc 311 is mounted on the connecting plate 314 and has an inclined annular grinding surface. The first lifting mechanism 32 is located at the lower end of the grinding mechanism 31 and includes a U-shaped... The frame 321 and the lifting drive 322 are included. The grinding mechanism 31 is located inside the U-shaped frame 321, and the lifting drive 322 is located at the bottom of the U-shaped frame 321. The output end of the lifting drive 322 is connected to the grinding mechanism 31. Two fixing mechanisms 4 are respectively located on both sides of the grinding device 3. The fixing mechanism 4 includes a moving structure 41 and a mounting plate 42. The moving structure 41 is embedded in the worktable 1, and the mounting plate 42 is located at the upper end of the moving structure 41 and is parallel to the worktable 1. The mounting plate 42 is provided with a control mechanism for clamping and rotating the workpiece. The control mechanism is existing technology. The linkage mechanism 5 includes a lifting plate 51, a second lifting mechanism 52, and two linkage structures 53. The lifting plate 51 is horizontally located at the lower end of the U-shaped frame 321. The second lifting mechanism 52 is located on the base 2 and is connected to the lifting plate 51. The two linkage structures 53 are respectively located on both sides of the U-shaped frame 321 and are connected to the U-shaped frame 321 and the moving structure 41.

[0036] When a cutting and welding machine tool in an industrial electromechanical intelligent processing system performs a processing task, firstly, the cutting device cuts the workpiece to form the required part. After cutting, the cutting device exits the working area. Then, the operator places two workpieces to be welded onto two fixed mechanisms 4, ensuring that the welding ends of the two workpieces are tightly fitted. The two fixed mechanisms 4 then clamp and fix the workpieces through their built-in control mechanisms. At this time, the linkage mechanism 5 starts to operate, and the second lifting mechanism 52 drives the lifting plate 51 to move vertically toward the worktable 1, thereby driving the entire grinding device 3 to rise. During the rising process of the grinding device 3, its U-shaped frame 321 is connected to two moving structures 41 through two linkage structures 53, pushing the moving structures 41 to move horizontally along the worktable 1, thereby driving the two mounting plates 42 and the workpieces fixed on them to move away from each other. When the distance between the welding surfaces of the two workpieces reaches the minimum diameter of the grinding surface of the grinding disc 311, the linkage mechanism 5 stops operating. Subsequently, the first lifting mechanism 32 starts, and the lifting drive... The actuator 322 drives the grinding mechanism 31 to continue rising until the grinding disc 311 is positioned between the two workpieces. At this point, the first rotating shaft 313 begins to rotate, causing the grinding disc 311 to rotate. The grinding surface of the grinding disc 311 simultaneously grinds the two workpieces. At the same time, the linkage mechanism 5 is activated again, and the second lifting mechanism 52 drives the lifting plate 51 to reciprocate vertically, thereby driving the entire grinding device 3 to reciprocate. During this process, the grinding disc 311 gradually penetrates towards the middle of the two workpieces, ensuring that its grinding surface makes full contact with both workpieces. Simultaneously, the control mechanism drives the workpieces to rotate, ensuring that the grinding surface can evenly cover the workpiece surface. Since the two workpieces are moving away from each other, the penetration of the grinding disc 311 into the workpieces is prevented from increasing. Finally, the welding device welds the two workpieces. The linkage structure 53 links the grinding mechanism 31 and the two workpieces, preventing the grinding disc 311 from jumping when in contact with the workpieces. This achieves uniform utilization of the grinding surface of the grinding disc 311 while enhancing the stability of the processing.

[0037] Reference Figure 4 and Figure 5 As shown: The linkage structure 53 includes two linkage plates 531 and a linkage shaft 532; the two linkage plates 531 are arranged parallel to each other, one end of the linkage plate 531 is axially connected to the U-shaped frame 321, and the other end of the linkage plate 531 is away from the U-shaped frame 321. A linkage groove is provided on the linkage plate 531; the two ends of the linkage shaft 532 are respectively slidably arranged in the two linkage grooves, and the middle part of the linkage shaft 532 is connected to the moving structure 41.

[0038] Because the grinding surface of the grinding disc 311 is designed with an inclined angle, in order to prevent the intrusion of the grinding surface into the workpiece during the lifting process from increasing, it is necessary to ensure that the ratio of the rising speed of the grinding disc 311 to the speed at which the two workpieces move away from each other remains constant. This is achieved by setting two linkage plates 531 and linkage shafts 532. The linkage plates 531 rotate around their shaft connection with the U-shaped frame 321, so that the inclination angle of the linkage plates 531 is the same as the inclination angle of the grinding disc 311. When the U-shaped frame 321 rises, the U-shaped frame 321 drives the four linkage plates 531 in the two linkage structures 53. Synchronous movement: Since the linkage shaft 532 is connected to the moving structure 41 and maintains a constant height, as the linkage plate 531 rises, the side wall of the linkage groove will apply a force to the linkage shaft 532, causing it to move away from the center of the worktable 1. This force is transmitted to the workpiece through the moving structure 41, causing the workpiece to move away from the center of the worktable 1. Since the tilt angle of the linkage plate 531 is consistent with the tilt angle of the grinding disc 311, the ratio between the rising speed of the grinding disc 311 and the moving speed of the workpiece can be kept constant, thereby effectively avoiding an increase in the intrusion of the grinding disc 311 into the workpiece.

[0039] Reference Figure 4 and Figure 6 As shown: The linkage mechanism 5 also includes two angle adjustment mechanisms 54, which are mounted on the lifting plate 51. Each angle adjustment mechanism 54 includes two adjustment plates 541, two connecting shafts 542, and a drive assembly 543. The two adjustment plates 541 correspond to two corresponding linkage plates 531 on both sides of the U-shaped frame 321, and the adjustment plates 541 are provided with adjustment grooves. The two connecting shafts 542 are slidably mounted in the adjustment grooves and are connected to the linkage plates 531. The drive assembly 543 is connected to the two adjustment plates 541. The drive assembly 543 includes a third lead screw 5431 and two third moving blocks 5432. The third lead screw 5431 is a bidirectional lead screw, and the two third moving blocks 5432 are respectively mounted at both ends of the third lead screw 5431 and are respectively connected to the two adjustment plates 541.

[0040] For workpieces of different diameters, the required bevel angles for grinding vary. Therefore, it is necessary to change to a suitable grinding disc 311 to achieve different bevel grinding effects. Simultaneously, the linkage structure 53 also needs corresponding adjustments. The two angle adjustment mechanisms 54 work in tandem. When it is necessary to increase the tilt angle of the linkage plate 531, the third lead screw 5431 in the drive assembly 543 rotates forward, causing the two third moving blocks 5432 to move away from each other. This action drives the connecting shaft 542 upward along the adjustment groove via the adjustment plate 541, thereby driving the linkage plate 531. Rotating around the axis of the linkage plate 531 and the U-shaped frame 321 increases the angle between the linkage plate 531 and the U-shaped frame 321. Conversely, when it is necessary to reduce the tilt angle of the linkage plate 531, the third lead screw 5431 rotates in the opposite direction, and the two third moving blocks 5432 move closer to each other. Through the action of the adjusting plate 541, the two linkage plates 531 move accordingly, reducing the angle with the U-shaped frame 321. This process ensures that the linkage plate 531 can remain parallel to the grinding surfaces of different grinding discs 311, thereby maintaining an effective linkage relationship between the grinding disc 311 and the workpiece.

[0041] Reference Figure 6 and Figure 7 As shown: The linkage mechanism 5 also includes a synchronous drive structure 55, which is disposed between the two angle adjustment mechanisms 54 and is connected to the two angle adjustment mechanisms 54 in a transmission manner. The synchronous drive structure 55 includes a second rotating shaft 551, two synchronous belt drive assemblies 552 and a second rotary driver 553. The second rotating shaft 551 is parallel to the third lead screw 5431. The two synchronous belt drive assemblies 552 are respectively disposed at both ends of the second rotating shaft 551. The synchronous belt drive assemblies 552 are used to connect the ends of the second rotating shaft 551 and the third lead screw 5431. The second rotary driver 553 is disposed in the middle of the second rotating shaft 551 and is connected to the second rotating shaft 551 in a transmission manner.

[0042] When the demand for activating the angle adjustment mechanism 54 is generated, the synchronous drive structure 55 operates, and the second rotary driver 553 drives the second rotating shaft 551 to rotate. This rotational motion is synchronously transmitted to the two third lead screws 5431 through the synchronous belt drive assemblies 552 at both ends, causing the two third lead screws 5431 to rotate at the same speed and direction. The two third lead screws 5431 then drive their respective associated angle adjustment mechanisms 54, ensuring that they can operate in a coordinated manner. This synchronous operation mechanism causes the four linkage plates 531 to move synchronously, thereby ensuring that the two ends of the linkage shaft 532 are subjected to balanced forces from the two linkage plates 531. Therefore, the forces exerted by the two linkage shafts 532 on the two moving structures 41 are consistent, thereby realizing the synchronous movement of the workpieces on the two mounting plates 42.

[0043] Reference Figure 4 and Figure 8 As shown: The second lifting mechanism 52 includes a second lead screw 521, two second moving blocks 522, and two second drive plates 523; the second lead screw 521 is horizontally arranged in the middle of the base 2, and both ends of the second lead screw 521 are connected to the base 2; the two second moving blocks 522 are respectively arranged at both ends of the second lead screw 521; the two second drive plates 523 correspond to the two second moving blocks 522 respectively, and both ends of the second drive plates 523 are axially connected to the lifting plate 51 and the second moving block 522 respectively; the second lifting mechanism 52 also includes a plurality of fourth guide structures 524, which are arranged between the base 2 and the lifting plate 51. The fourth guide structure 524 includes a guide sleeve 5241 and a lifting shaft 5242. The guide sleeve 5241 is fixed on the base 2, the lifting shaft 5242 is fixedly connected to the lifting plate 51, and the other end of the lifting shaft 5242 is slidably arranged in the guide sleeve 5241.

[0044] When it is necessary to control the grinding disc 311 to intrude between two workpieces, the second lead screw 521 rotates in the forward direction, driving the two second moving blocks 522 to move towards each other, causing the two second drive plates 523 to move synchronously, applying an upward driving force to the lifting plate 51, causing the lifting plate 51 to rise. During the rising process, the lifting plate 51 is constrained by the fourth guide structure 524, that is, the lifting shaft 5242 slides along the axial direction in the guide sleeve 5241, ensuring that the lifting plate 51 rises smoothly and linearly, while the grinding disc 311 in the grinding device 3 installed on the lifting plate 51 rises horizontally, thereby ensuring that the grinding disc 311 can contact the two workpieces at the same time.

[0045] Reference Figure 9 As shown: Both ends of the U-shaped frame 321 are provided with first sliding grooves, and each of the two first sliding grooves is provided with a first guide structure 323. The two first guide structures 323 are connected to the grinding mechanism 31. The first guide structure 323 includes a first guide post 3231 and a first slider 3232. The first guide post 3231 is connected to the U-shaped frame 321, and the first slider 3232 is slidably disposed on the first guide post 3231 and is connected to the rectangular frame 312.

[0046] The movement of the grinding disc 311 is controlled not only by the vertical lifting of the second lifting mechanism 52, but also by the vertical lifting of the first lifting mechanism 32. When the lifting driver 322 is activated and drives the rectangular frame 312 to move, the rectangular frame 312 will pull the two first sliders 3232 to slide synchronously along the two first guide posts 3231 respectively. During this process, the two first sliders 3232 are each restricted by the corresponding first guide posts 3231, ensuring that the movement of both sides of the rectangular frame 312 is synchronized. The grinding disc 311 connected to the rectangular frame 312 also exhibits a smooth translational movement, thereby effectively avoiding the skewness or asynchrony of the rectangular frame 312 and the grinding disc 311 during the translation process, and further ensuring that the grinding disc 311 can contact two workpieces at the same time.

[0047] Reference Figure 9 and Figure 10 As shown: The grinding device 3 also includes a locking structure 33, which includes a second guide structure 331 and two locking components 332. The second guide structure 331 is located at the lower end of the grinding mechanism 31, with its two ends facing the two ends of the U-shaped frame 321. The second guide structure 331 includes a second guide post 3311, two second sliders 3312, and two first drive plates 3313. The second guide post 3311 is connected to the rectangular frame 312, and the two second sliders 3312 are slidably mounted on the second guide post 3311. The two ends of the first drive plates 3313 are axially connected to the output ends of the second sliders 3312 and the lifting driver 322, respectively. The two locking components 332 are located at the two ends of the second guide structure 331 and are connected to the second guide structure 331. The locking components 332 include a locking block 3321 and a locking groove 3322. The locking block 3321 is connected to the second slider 3312, and the locking groove 3322 is fixed on the U-shaped frame 321.

[0048] During the polishing process, the lifting driver 322 is responsible for maintaining the height difference between the polishing disc 311 and the U-shaped frame 321. However, because the polishing disc 311 vibrates and is subjected to a downward vertical force during operation, the height difference changes, thus affecting the polishing effect. By setting a locking structure 33, when the lifting driver 322 applies an upward force, the two first drive plates 3313 respectively push the two second sliders 3312 to move along the second guide post 3311 toward both ends of the second guide post 3311. The second sliders 3312 first drive... The end of the locking block 3321 contacts the inner wall of the U-shaped frame 321. As the lifting drive 322 continues to apply an upward force, the rectangular frame 312 and the second slider 3312 rise synchronously. During this process, the locking block 3321 slides along the inner wall of the U-shaped frame 321 until it is fully inserted into the locking groove 3322. At this time, the movement of the rectangular frame 312 stops, thus fixing the relative position between the rectangular frame 312 and the U-shaped frame 321, thereby effectively preventing changes in the height difference between the grinding disc 311 and the U-shaped frame 321.

[0049] Reference Figure 3 and Figure 11 As shown: The movable structure 41 includes a movable plate 411 and two third guide structures 412; the movable plate 411 is parallel to the worktable 1; the two third guide structures 412 are respectively disposed on both sides of the movable plate 411, and the third guide structures 412 are connected to the movable plate 411 and the worktable 1. The third guide structure 412 includes a third guide post 4121 and a third slider 4122. The two ends of the third guide post 4121 are connected to the worktable 1, and the third slider 4122 is slidably disposed on the third guide post 4121, and the third slider 4122 is connected to the movable plate 411.

[0050] One end of the connecting shaft 542 is connected to the moving plate 411. Driven by the linkage structure 53, when the connecting shaft 542 moves horizontally away from the middle position of the worktable 1, it will push the moving plate 411 to move synchronously. During this process, the moving plate 411 will drive the two third sliders 4122 to slide along their respective third guide posts 4121. The third guide posts 4121 play a limiting role in this process, ensuring that the moving plate 411 always maintains a translational state, avoiding any unnecessary offset or rotation. As the moving plate 411 moves smoothly, the mounting plate 42 at its upper end and the mounted workpiece will also move accordingly, thereby avoiding offset or rotation during the movement and improving the processing accuracy.

[0051] Reference Figure 11 and Figure 12As shown: The fixing mechanism 4 also includes an intrusion mechanism 43, which is disposed on the moving plate 411 and connected to the mounting plate 42. The intrusion mechanism 43 includes a first lead screw 431, a first moving block 432 and a first rotary driver 433. The two ends of the first lead screw 431 are connected to the moving plate 411, the first moving block 432 is threadedly connected to the first lead screw 431, and the first rotary driver 433 is disposed at one end of the first lead screw 431 and is drivenly connected to the first lead screw 431.

[0052] When the two workpieces move synchronously with the grinding disc 311, the depth of the grinding disc 311 penetrating the workpiece remains constant. At this time, the two penetration mechanisms 43 are activated simultaneously. The first rotary driver 433 drives the first lead screw 431 to rotate, thereby providing the first moving block 432 with the driving force to move along the first lead screw 431. The first moving block 432 then moves toward the center of the worktable 1, while simultaneously driving the mounting plate 42 and its fixed workpiece to move closer to the center of the grinding disc 311. This movement process causes the overlapping area between the workpiece and the grinding disc 311 to gradually increase, and the part of the workpiece being ground also increases accordingly, thereby realizing the penetration grinding of the workpiece by the grinding disc 311.

[0053] Reference Figure 11 and Figure 13 As shown: The fixing mechanism 4 also includes an adjustment structure 44, which is located at one end of the mounting plate 42 away from the middle of the worktable 1. The adjustment structure 44 includes a frame plate 441 and an adjustment bolt 442. The frame plate 441 is vertically arranged at the upper end of the mounting plate 42, and one end of the adjustment bolt 442 passes vertically through the frame plate 441 and faces the middle of the worktable 1.

[0054] When the welded ends of two workpieces abut, they may deviate from the middle surface of the grinding disc 311. When the grinding disc 311 moves in conjunction with the two workpieces, the distance between the two workpieces and the grinding disc 311 changes differently. By setting two adjustment structures 44, since the distance between the end of the mounting plate 42 and the middle surface of the grinding disc 311 is fixed, the operator adjusts the distance between the end of the adjusting bolt 442 and the end of the mounting plate 42 according to the length of the workpiece to be processed. This makes the distance between the end of the adjusting bolt 442 and the end of the mounting plate 42 equal to the difference between the distance between the end of the mounting plate 42 and the middle surface of the grinding disc 311 and the length of the workpiece. One end of the workpiece is pressed against the end of the adjusting bolt 442, and the other end of the workpiece is coplanar with the middle surface of the grinding disc 311. Therefore, the two workpieces move simultaneously from the middle surface of the grinding disc 311 to both sides, thereby achieving the same distance between the grinding disc 311 and the ends of the two workpieces.

Therefore, the protection scope of the present invention should be determined by the appended claims.
