[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 to Figure 2 As shown, the present invention provides an embodiment: an automatic diamond saw blade welding machine, including an equipment base 1, the top of the equipment base 1 is fixedly connected with a support base 2 and a protective cover 3, the top of the support base 2 is detachably mounted with a loading platform 4, the top of the loading platform 4 is fixedly connected with a feeding track 5, a loading drive assembly 6 is arranged inside the support base 2, a welding assembly 7 is arranged on the loading platform 4, the loading drive assembly 6 includes a clamping mechanism 61, a loading mechanism 62 and a driving mechanism 63, and the welding assembly 7 includes a welding mechanism 71 and a feeding mechanism 72.

[0040] When the embodiment of the present invention is actually used, the feeding drive assembly 6 and the welding assembly 7 cooperate with each other to realize automatic welding of the diamond saw blade. First, the clamping mechanism 61 clamps and fixes the saw blade base, and the feeding mechanism 62 drives the clamping mechanism 61 to move into the welding mechanism 71. During the movement, the driving mechanism 63 cooperates with the clamping mechanism 61 to move and clamp the saw blade base. Then, the driving mechanism 63 that matches its specifications is selected according to the size of the saw blade to ensure that the welding position of the cutter head is equal to the rotation angle. In addition, the driving mechanism 63 can also drive the feeding mechanism 72 to push the cutter head to realize feeding during the driving process, ensuring the synchronization of feeding and rotation of the base. Finally, the welding mechanism 71 is energized to realize heating of the docking part between the cutter head and the base, thereby completing the automatic welding of the diamond saw blade and improving the welding efficiency and welding quality.

[0041] like Figures 3 to 9 As shown, the clamping mechanism 61 includes a movable seat 611 slidably connected to the inside of the support seat 2, the movable seat 611 is internally rotatably connected to the drive shaft 613, the outer side of the drive shaft 613 is symmetrically fixedly connected to the second fixed block 618, the outer side wall of the movable seat 611 is rotatably connected to the support plate 614, the support plate 614 is fixedly connected to the two second fixed blocks 618, the outer side wall of the support plate 614 is fixedly connected to the fixed sleeve 612, the drive shaft 613 and the movable seat 611 are slidably connected with a movable sleeve 615, the outer side of the drive shaft 613 is rotatably connected to the internal threaded sleeve 616, the internal threaded sleeve 616 and the movable sleeve 615 are threadedly connected, and a connecting rod structure is symmetrically arranged between the fixed sleeve 612 and the movable sleeve 615.

[0042] When the embodiment of the present invention is actually applied, the movable seat 611 in the clamping mechanism 61 can slide inside the support seat 2, providing a basis for the movement of the entire clamping mechanism 61, and the driving shaft 613 rotates inside the movable seat 611, and the second fixed block 618 symmetrically fixed on its outer side is fixedly connected to the support plate 614 rotatably connected to the outer wall of the movable seat 611, so that when the driving shaft 613 rotates, it can drive the support plate 614 to rotate, and the fixed sleeve 612 on the outer wall of the support plate 614 cooperates with the movable sleeve 615. When the internal threaded sleeve 616 on the outer side of the driving shaft 613 rotates, since the internal threaded sleeve 616 is threadedly connected to the movable sleeve 615, the movable sleeve 615 can slide on the driving shaft 613, and the connecting rod structure symmetrically arranged between the fixed sleeve 612 and the movable sleeve 615 is triggered when the movable sleeve 615 moves, thereby clamping and fixing the saw blade base, so as to ensure that the saw blade base is stably clamped during the automatic welding process of the diamond saw blade, providing reliable protection for subsequent welding operations.

[0043] like Figures 3 to 5As shown, the feeding mechanism 62 includes a non-full rack 623 fixedly connected to the inner wall of the support seat 2, a gear 624 is fixedly connected to the outer side of the internal threaded sleeve 616, the non-full rack 623 passes through the movable seat 611 and meshes with the gear 624, a connecting block 622 is symmetrically fixedly connected to the outer wall of the movable seat 611, a hydraulic rod 621 is fixedly connected between the connecting block 622 and the inner wall of the support seat 2, and mounting grooves are symmetrically opened on the inner wall of the support seat 2, and the hydraulic rod 621 and the connecting block 622 are both located in the mounting grooves.

[0044] When the embodiment of the present invention is actually used, the non-full rack 623 in the feeding mechanism 62 is fixedly connected to the inner wall of the support seat 2. When the gear 624 on the outer side of the internal threaded sleeve 616 rotates through the non-full rack 623 as the internal threaded sleeve 616 rotates, the non-full rack 623 and the gear 624 are meshed with each other, which will drive the internal threaded sleeve 616 to rotate, thereby triggering the clamping mechanism 61. The connecting block 622 symmetrically fixed on the outer wall of the movable seat 611 cooperates with the hydraulic rod 621 between the inner wall of the support seat 2 to provide power for the movement of the movable seat 611. The mounting grooves symmetrically opened on the inner wall of the support seat 2 provide installation space for the hydraulic rod 621 and the connecting block 622. During the automatic welding process of the diamond saw blade, the feeding mechanism 62 and the clamping mechanism 61 work together to ensure that the saw blade base can be accurately moved to the welding position, thereby improving the welding efficiency.

[0045] like Figure 5 and Fig.10 As shown, the driving mechanism 63 is used to intermittently drive the saw blade base to rotate to adjust the position. The driving mechanism 63 includes a mounting plate 631 fixedly connected to the bottom of the movable seat 611, and a groove wheel 632 is detachably mounted on the outer side of the driving shaft 613. A servo motor 634 is fixedly mounted on the bottom of the mounting plate 631, and a dial 633 is fixedly mounted on the output end of the servo motor 634 through a coupling. The dial 633 and the groove wheel 632 are connected in stages through transmission, and the fixed sleeve 612, the driving shaft 613, the movable sleeve 615 and the dial 633 are on the same axis.

[0046] When the embodiment of the present invention is actually used, the mounting plate 631 in the driving mechanism 63 is fixedly connected to the bottom of the movable seat 611 to provide mounting support for components such as the servo motor 634. The groove wheel 632 detachably mounted on the outer side of the driving shaft 613 is connected to the output end of the servo motor 634 in a staged transmission manner through a dial 633 fixedly mounted via a coupling, so that the servo motor 634 can intermittently drive the saw blade base to rotate, thereby achieving precise adjustment of the position of the saw blade base and ensuring that the welding position of the cutter head is consistent with the rotation angle of the saw blade base. The fixed sleeve 612, the driving shaft 613, the movable sleeve 615 and the dial 633 are on the same axis, thereby ensuring the accuracy and stability of the transmission, so that during the automatic welding of the diamond saw blade, the driving mechanism 63 can accurately adjust the position of the saw blade base according to the welding requirements to ensure the quality and efficiency of the welding.

[0047] like Figure 1 , Fig.11 , Fig.12 and Fig.13 As shown, the welding mechanism 71 includes a limit seat 711 fixedly connected to the support seat 2 and the loading platform 4, and a power supply slide 713 is slidably connected inside the loading platform 4. A welding block 712 is respectively arranged in the limit seat 711 and the loading platform 4, one of the welding blocks 712 is fixedly installed inside the limit seat 711, and the other welding block 712 is slidably connected inside the loading platform 4, a spring 2 715 is fixedly connected between the welding block 712 and the power supply slide 713, and a power supply contact 714 is fixedly connected to one end of the welding block 712 close to the power supply slide 713.

[0048] When the embodiment of the present invention is actually used, the limit seat 711 in the welding mechanism 71 is fixedly connected to the support seat 2 and the feeding platform 4, providing stable support and limit for the welding operation. The power supply slide 713 slidably connected inside the feeding platform 4 can play a role of pushing and power supply during the welding process. The welding blocks 712 are respectively arranged in the limit seat 711 and the feeding platform 4, one of which is fixedly installed inside the limit seat 711, and the other is slidably connected to the feeding platform 4. It is connected to the power supply slide 713 through the spring 2 715, so that the welding block 712 can move elastically within a certain range to meet the welding requirements of cutter heads and substrates of different sizes. The welding block 712 is close to the power supply contact 714 fixedly connected at one end of the power supply slide 713. When the welding block 712 and the power supply slide 713 are in contact with each other, the power supply contact 714 and the power supply slide 713 are energized to provide the required power for the welding process. During the automatic welding process of the diamond saw blade, the welding mechanism 71 can accurately heat and weld the butt joints of the cutter head and the substrate to ensure the welding quality and stability.

[0049] like Fig.11As shown, the feeding mechanism 72 is used to drive the welding block 712 to realize the loading and fixing of the cutter head. The feeding mechanism 72 includes a reciprocating screw 721 rotatably connected to the inside of the loading platform 4, and a connecting plate 722 is fixedly connected to the outer wall of the power supply slide 713. A spiral pair transmission is formed between the connecting plate 722 and the reciprocating screw 721, and a friction wheel 723 is fixedly connected to the outer side of the reciprocating screw 721.

[0050] When the embodiment of the present invention is actually applied, the reciprocating screw 721 in the feeding mechanism 72 that is rotatably connected to the inside of the loading platform 4 starts to rotate under power drive, and the connecting plate 722 fixedly connected to the outer wall of the power supply slide 713 forms a spiral pair transmission relationship with the reciprocating screw 721. As the reciprocating screw 721 rotates, the connecting plate 722 will move linearly along the reciprocating screw 721, and the friction wheel 723 fixedly connected to the outside of the reciprocating screw 721, through cooperation with the support plate 614, provides a power source for the rotation of the reciprocating screw 721, so that the connecting plate 722 drives the power supply slide 713 to move linearly, and then drives the welding block 712 to load and fix the cutter head at the appropriate position, ensuring that the cutter head can be more accurately butt-welded to the substrate, thereby ensuring the quality of welding.

[0051] like Figure 8 and Fig. 9 As shown, the connecting rod structure includes a connecting rod 1 617b and a connecting rod 2 617c, which are hinged to each other, a slider 617a is fixedly connected to the outer side of the movable sleeve 615, a first fixed block 617d is fixedly connected to the inside of the fixed sleeve 612, an end of the connecting rod 1 617b away from the connecting rod 2 617c is hinged to the slider 617a, an end of the connecting rod 2 617c away from the connecting rod 1 617b is hinged to the first fixed block 617d, a limiting rod 617e is fixedly connected to the inside of the fixed sleeve 612, the slider 617a and the connecting rod 1 617b are both slidably connected to the outer side of the limiting rod 617e, and a spring 1 617f is fixedly connected between the slider 617a and the fixed sleeve 612.

[0052] In actual application of the embodiment of the present invention, the first link 617b and the second link 617c in the link structure are hinged to each other, and the rotation angle range of the first link 617b and the second link 617c is certain, forming a movable link structure, and the slider 617a fixedly connected to the outside of the movable sleeve 615 and the first fixed block 617d of the component fixedly connected to the inside of the fixed sleeve 612 are linked by the hinge relationship between the first link 617b and the second link 617c. When the movable sleeve 615 moves, the slider 617a moves accordingly, and the slider 617a is connected to the first link 617b and the second link 617c by the hinge relationship between the first link 617b and the second link 617c. The transmission effect of 17c drives the second connecting rod 617c and the first fixed block 617d to perform corresponding actions, thereby achieving the clamping of the saw blade base. At the same time, the limiting rod 617e fixedly connected inside the fixed sleeve 612 limits the slider 617a and the connecting rod 1 617b, ensuring that they slide along the outer side of the limiting rod 617e to ensure the accuracy and stability of the clamping action. The spring 1 617f fixedly connected between the slider 617a and the fixed sleeve 612 can push the slider 617a to achieve the initial clamping of the saw blade base by the connecting rod structure.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
