Description

Technical Field

[0001] The present invention relates to the technical field of industrial electromechanical manufacturing, and in particular to a cutting and welding machine tool for industrial electromechanical intelligent processing. Background Art

[0002] In the field of industrial electromechanical manufacturing, cutting and welding machine tools are indispensable and important equipment, and their technical level directly affects product quality and production efficiency. The advancement of cutting and welding machine tool technology helps to improve the efficiency and product quality of industrial production and promote the continuous development of the field of industrial electromechanical processing. At present, the ports of the welded parts need to be grooved during the welding process, and the efficiency of groove grinding directly affects the efficiency of welding production.

[0003] The patent with announcement number CN118456036B discloses an industrial electromechanical manufacturing cutting and welding machine tool, whose working principle is: when the groove grinding device 5 performs groove grinding on two workpieces 2, the staff places the two workpieces 2 on both sides of the groove grinding device 5 respectively, and the grinding surfaces of the first grinding disc 51 and the second grinding disc 54 are respectively facing the two workpieces 2, and the third driving structure 53 drives the second rotating shaft 52 to rotate, and the second rotating shaft 52 drives the first grinding disc 51 and the second grinding disc 54 to rotate simultaneously, and the first grinding disc 51 and the second grinding disc 54 grind the two welding end faces of the two workpieces 2 simultaneously. During the grinding process, the fourth driving structure 553 works, and the second bidirectional screw The rotation of rod 5532 makes the two second moving blocks 5533 move away from each other, and the second spring 554 releases part of the elastic potential energy. The second spring 554 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, so that the distance between the first grinding disc 51 and the second grinding disc 54 increases. When the first grinding disc 51 and the second grinding disc 54 move downward under the action of the adjustment mechanism 7, the outer sides of the grinding surfaces of the first grinding disc 51 and the second grinding disc 54 will contact the workpiece 2, so that the outer sides of the grinding surfaces of the first grinding disc 51 and the second grinding disc 54 participate in the groove grinding work, thereby achieving uniform wear of the grinding surfaces of the first grinding disc 51 and the second grinding disc 54.

[0004] Although the above scheme realizes the simultaneous grinding of two workpieces and improves the grinding efficiency, the first grinding disc and the second grinding disc will have severe friction with the workpieces during grinding, causing the first grinding disc and the second grinding disc to vibrate, and then causing the second spring between the first grinding disc and the second grinding disc to vibrate. Therefore, the first grinding disc and the second grinding disc will jump along the axis of the second rotating shaft during the grinding process. The contact between the jumping first grinding disc and the second grinding disc and the workpiece not only has a poor grinding effect, but also aggravates the jumping of the first grinding disc and the second grinding disc.

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] When the cutting and welding machine tool of industrial electromechanical intelligent processing performs processing tasks, first, the cutting device cuts the workpiece to form the required part. After the cutting is completed, the cutting device withdraws from the working area. Then, the staff places the two workpieces to be welded on the two fixing mechanisms 4 respectively to ensure that the welding ends of the two workpieces are tightly fitted. The two fixing mechanisms 4 then clamp 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 toward the workbench 1 in the vertical direction, 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 the two moving structures 41 through two linkage structures 53, pushing the moving structure 41 to move horizontally along the workbench 1, thereby driving the two mounting plates 42 and the workpieces fixed thereon 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 disk 311, the linkage mechanism 5 stops operating. Then, the first lifting mechanism 32 is started, and the lifting drive The actuator 322 drives the grinding mechanism 31 to continue to rise until the grinding disc 311 is located between the two workpieces. At this time, the first rotating shaft 313 starts to rotate, driving the grinding disc 311 to rotate, and the grinding surface of the grinding disc 311 grinds the two workpieces at the same time. At the same time, the linkage mechanism 5 is started again, and the second lifting mechanism 52 drives the lifting plate 51 to lift and reciprocate in the vertical direction, thereby driving the grinding device 3 to lift and reciprocate as a whole. During this process, the grinding disc 311 gradually invades toward the middle of the two workpieces, and its grinding surface can fully contact the two workpieces. At the same time, the control mechanism drives the workpiece to rotate to ensure that the grinding surface can evenly cover the surface of the workpiece. Since the two workpieces are moving away from each other, the increase in the part of the grinding disc 311 invading the workpiece is avoided. Finally, the welding device welds the two workpieces, and the grinding mechanism 31 and the two workpieces are linked by the linkage structure 53 to avoid the jumping of the grinding disc 311 when it contacts the workpiece, thereby achieving uniform utilization of the grinding surface of the grinding disc 311 and 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, and a linkage slide groove is opened on the linkage plate 531; the two ends of the linkage shaft 532 are respectively slidably arranged in the two linkage slide grooves, and the middle part of the linkage shaft 532 is connected to the moving structure 41.

[0038] Since the grinding surface of the grinding disc 311 is designed with an inclined angle, in order to prevent the grinding surface from invading the workpiece more during the lifting process, it is necessary to ensure that the ratio of the rising speed of the grinding disc 311 and the speed at which the two workpieces move away from each other is maintained constant. By setting two linkage plates 531 and linkage shafts 532, the linkage plate 531 is rotated around the axial connection between it and the U-shaped frame 321, so that the inclination angle of the linkage plate 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 slide groove will apply a force to the linkage shaft 532 to make it move away from the middle of the workbench 1. This force is transmitted to the workpiece through the moving structure 41, so that the workpiece moves away from the middle of the workbench 1. Since the inclination angle of the linkage plate 531 is consistent with the inclination angle of the grinding disc 311, it can ensure that the ratio between the rising speed of the grinding disc 311 and the speed of the workpiece moving away is constant, thereby effectively avoiding an increase in the part of the grinding disc 311 that invades the workpiece.

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

[0040] For workpieces of different diameters, the groove angles required for grinding are different. At this time, it is necessary to replace the appropriate grinding disc 311 to achieve groove grinding effects at different angles. At the same time, the linkage structure 53 also needs to be adjusted accordingly. The two angle adjustment mechanisms 54 work together. When it is required to increase the inclination angle of the linkage plate 531, the third screw rod 5431 in the driving assembly 543 rotates forward, causing the two third moving blocks 5432 to move away from each other. This action drives the connecting shaft 542 to move upward along the adjustment slot through the adjustment plate 541, thereby driving the linkage plate 531. It rotates around the axial joint with the U-shaped frame 321 to increase the angle between the linkage plate 531 and the U-shaped frame 321. Conversely, when the inclination angle of the linkage plate 531 needs to be reduced, the third screw rod 5431 rotates in the opposite direction, and the two third moving blocks 5432 approach each other. Through the action of the adjusting plate 541, the two linkage plates 531 move accordingly to reduce 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 arranged between the two angle adjustment mechanisms 54, and the synchronous drive structure 55 is transmission-connected to the two angle adjustment mechanisms 54, the synchronous drive structure 55 includes a second rotating shaft 551, two synchronous belt drive assemblies 552 and a second rotation driver 553, the second rotating shaft 551 is parallel to the third screw rod 5431, the two synchronous belt drive assemblies 552 are respectively arranged at both ends of the second rotating shaft 551, the synchronous belt drive assemblies 552 are used to connect the end of the second rotating shaft 551 and the third screw rod 5431, the second rotation driver 553 is arranged in the middle of the second rotating shaft 551, and the second rotation driver 553 is transmission-connected to the second rotating shaft 551.

[0042] When the need to start the angle adjustment mechanism 54 arises, the synchronous drive structure 55 operates, and the second rotation driver 553 drives the second rotating shaft 551 to rotate. The rotation action is synchronously transmitted to the two third screw rods 5431 through the synchronous belt drive assemblies 552 at both ends, so that the two third screw rods 5431 rotate at the same speed and direction. The two third screw rods 5431 then drive their respective associated angle adjustment mechanisms 54 to ensure that the two can operate in a coordinated manner. This synchronous operation mechanism enables the four linkage plates 531 to achieve synchronous movement, thereby ensuring that both 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 remain consistent, thereby achieving 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 screw rod 521, two second moving blocks 522 and two second driving plates 523; the second screw rod 521 is horizontally arranged in the middle of the base 2, and the two ends of the second screw rod 521 are connected to the base 2; the two second moving blocks 522 are respectively arranged at the two ends of the second screw rod 521; the two second driving plates 523 correspond to the two second moving blocks 522 respectively, and the two ends of the second driving plate 523 are respectively axially connected to the lifting plate 51 and the second moving blocks 522; the second lifting mechanism 52 also includes a plurality of fourth guide structures 524, and the plurality of fourth guide structures 524 are arranged between the base 2 and the lifting plate 51, and 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 disk 311 to invade between the two workpieces, the second screw rod 521 rotates forward, driving the two second moving blocks 522 to move toward each other, causing the two second driving 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 of the lifting plate 51, 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 steadily and linearly, and the grinding disk 311 in the grinding device 3 installed on the lifting plate 51 rises horizontally, thereby ensuring that the grinding disk 311 can contact the two workpieces at the same time.

[0045] Reference Fig. 9 As shown: both ends of the U-shaped frame 321 are provided with a first slide groove, and the two first slide grooves are 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 column 3231 and a first slider 3232. The first guide column 3231 is connected to the U-shaped frame 321, and the first slider 3232 is slidably set on the first guide column 3231, and the first slider 3232 is connected to the rectangular frame 312.

[0046] The movement of the grinding disc 311 is not only controlled 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 started 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 pillars 3231 respectively. During this process, the two first sliders 3232 are respectively restricted by the corresponding first guide pillars 3231, ensuring the synchronization of the movement of the two sides of the rectangular frame 312. The grinding disc 311 connected to the rectangular frame 312 also exhibits a smooth translational motion, thereby effectively avoiding the deflection or asynchronism 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 Fig. 9 and Fig.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 arranged at the lower end of the grinding mechanism 31, and the two ends of the second guide structure 331 are respectively facing the two ends of the U-shaped frame 321, the second guide structure 331 includes a second guide column 3311, two second sliders 3312 and two first drive plates 3313, the second guide column 3311 is connected to the rectangular frame 312, the two second sliders 3312 are slidably arranged on the second guide column 3311, and the two ends of the first drive plate 3313 are respectively axially connected to the second slider 3312 and the output end of the lifting driver 322; the two locking components 332 are respectively arranged at the two ends of the second guide structure 331, and the locking component 332 is connected to the second guide structure 331, and the locking component 332 includes 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 grinding process, the lifting drive 322 is responsible for maintaining the height difference between the grinding disc 311 and the U-shaped frame 321. However, since the grinding disc 311 will vibrate and be subjected to a vertical downward force during operation, the height difference will change, thereby affecting the grinding effect. By setting a locking structure 33, when the lifting drive 322 applies an upward force, the two first driving plates 3313 respectively push the two second sliders 3312 to move along the second guide column 3311 toward the two ends of the second guide column 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 driver 322 continues to apply 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, and the relative position between the rectangular frame 312 and the U-shaped frame 321 is fixed, thereby effectively preventing the change of the height difference between the grinding disc 311 and the U-shaped frame 321.

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

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

[0051] Reference Fig.11 and Fig.12As shown: the fixing mechanism 4 also includes an intrusion mechanism 43, which is arranged on the moving plate 411 and connected to the mounting plate 42. The intrusion mechanism 43 includes a first screw rod 431, a first moving block 432 and a first rotation driver 433. Both ends of the first screw rod 431 are connected to the moving plate 411, the first moving block 432 is threadedly connected to the first screw rod 431, and the first rotation driver 433 is arranged at one end of the first screw rod 431, and the first rotation driver 433 is transmission-connected to the first screw rod 431.

[0052] When the two workpieces keep moving synchronously with the grinding disk 311, the depth of the grinding disk 311 penetrating into the workpiece is maintained constant. At this time, the two intrusion mechanisms 43 are started at the same time, and the first rotary driver 433 drives the first screw rod 431 to rotate, thereby providing a driving force for the first moving block 432 to move along the first screw rod 431. The first moving block 432 then moves toward the center of the workbench 1, and at the same time drives the mounting plate 42 and the workpiece fixed thereon to approach the center of the grinding disk 311. This movement process causes the overlapping area between the workpiece and the grinding disk 311 to gradually increase, and the polished portion of the workpiece also increases accordingly, thereby realizing the intrusion grinding of the workpiece by the grinding disk 311.

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

[0054] When the welding ends of the two workpieces are abutted, the welding ends of the two workpieces may deviate from the middle surface of the grinding disk 311. When the grinding disk 311 is linked with the two workpieces, the distance between the two workpieces and the grinding disk 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 disk 311 is fixed, the staff 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, so that the distance between the end of the adjusting bolt 442 and the end of the mounting plate 42 is equal to the distance between the end of the mounting plate 42 and the middle surface of the grinding disk 311 minus the difference in the length of the workpiece, and one end of the workpiece is pressed against the end of the adjusting bolt 442, and the other end surface of the workpiece is coplanar with the middle surface of the grinding disk 311. Therefore, the two workpieces move from the middle surface of the grinding disk 311 toward both sides at the same time, thereby achieving the same distance between the grinding disk 311 and the ends of the two workpieces.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
