Description

Technical Field

[0001] This invention relates to the field of diamond saw blade welding technology, and particularly to a welding device for diamond saw blades. Background Technology

[0002] A diamond saw blade is a cutting tool widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics. A diamond saw blade mainly consists of two parts: the matrix and the cutting head. The matrix is ​​the main supporting part that holds the cutting head together, while the cutting head is the part that performs the cutting action during use. The cutting head is continuously worn down during use, while the matrix is ​​not. The cutting head is able to cut because it contains diamond, the hardest known substance. Diamond, through friction, cuts the workpiece within the cutting head, and the diamond particles are encased in metal inside the cutting head.

[0003] Chinese Patent Publication No. CN215238969U discloses a welding device for diamond saw blades, belonging to the field of saw blade processing. The device includes a workbench, a welding machine bolted to the top of the workbench, and a diamond saw blade. A mounting frame is bolted to the top of the workbench, and the diamond saw blade is mounted on the upper side of the mounting frame. The mounting frame has a moving component and a mounting component. The diamond saw blade is mounted on the moving component, which is connected to the mounting component to enable movement. The mounting component has a rotating component. Shims are used to increase the contact area, reduce pressure, and prevent loosening, achieving a better tightening effect on the diamond saw blade. A drive motor output drives a small gear to rotate, which in turn drives a meshing large gear to rotate slowly. The large gear drives a support frame to rotate, which in turn drives a limiting disc to rotate, achieving automatic rotation of the diamond saw blade, reducing manual operation and improving accuracy.

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1, as Figure 1 and Figure 2 As shown, a welding device for diamond saw blades includes a housing 1, with support legs 2 fixedly connected to the four corners of the lower end of the housing 1, two cabinet doors 3 rotatably connected to the front end of the housing 1, a cabinet door 4 rotatably connected to the left end of the housing 1, a pressing component 6 provided on the right side of the inner surface of the housing 1, a welding mechanism 7 fixedly installed on the right side of the inner surface of the housing 1, and an auxiliary positioning component 5 provided on the inner surface of the housing 1.

[0035] In this embodiment, the substrate is placed on the auxiliary positioning component 5. Then, the auxiliary positioning component 5 drives the substrate to move to the right on the inner surface of the outer shell 1. During the movement, the substrate is automatically adsorbed, fixed, and rotated to apply welding powder solution. After moving to the set position, the substrate is precisely limited. At this time, the operator places the diamond cutting head and combines it with the welding powder solution on the outer surface of the substrate. Then, the pressing component 6 presses and fixes the substrate. The welding mechanism 7 performs welding operations on the substrate and the diamond cutting head. The pressing component 6 drives the substrate and the diamond cutting head to rotate at a set angle.

[0036] The welding mechanism 7 mentioned above is a mature welding machine technology and equipment in the prior art. In this solution, it is used to weld the substrate and the diamond cutting head. Its internal structure, principle and connection method will not be described further.

[0037] Specifically, to achieve precise positioning of the substrate and diamond tip and application of soldering powder solution, refer to... Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the auxiliary positioning component 5 includes a partition 51 fixedly connected to the inner surface of the outer shell 1. A placement mechanism 52 is provided on the inner surface of the partition 51. An adsorption mechanism 53 is provided on the lower part of the inner surface of the outer shell 1. A solder powder solution mechanism 54 is provided on the upper front part of the partition 51. A positioning mechanism 55 is provided on the inner surface of the placement mechanism 52. An ejection mechanism 56 is provided on the inner surface of the placement mechanism 52.

[0038] For further details, please refer to [link / reference]. Figure 3 and Figure 4 In this embodiment, the placement mechanism 52 includes a slider 522 that is slidably connected to the inner surface of the partition 51. The inner surface of the outer shell 1 and the inner surface of the partition 51 are rotatably connected to a threaded rod 523 that is threadedly connected to the slider 522. The inner surface of the slider 522 is rotatably connected to a hollow rod 526 that is slidably connected to the partition 51. The upper end of the hollow rod 526 is fixedly connected to a placement disk 525. The left end of the outer shell 1 is fixedly connected to a servo motor 524. The output end of the servo motor 524 is fixedly connected to the left end of the threaded rod 523 through a coupling.

[0039] For further details, please refer to [link / reference]. Figure 3 and Figure 5In this embodiment, the adsorption mechanism 53 includes a guide rail 531 fixedly connected to the lower part of the inner surface of the outer shell 1, a round rod 532 rotatably connected to the inner surface of the hollow rod 526, four suction cups 533 fixedly connected to the inner surface of the placement tray 525, a connecting tube 534 fixedly connected to the lower part of the inner surface of the four suction cups 533 and extending through the inner surface of the round rod 532, the connecting tube 534 being rotatably connected to the round rod 532, a piston rod 535 slidably connected to the inner surface of the round rod 532, a roller 537 slidably connected to the guide rail 531 fixedly connected to the lower end of the piston rod 535, and a spring 536 sleeved on the outer surface of the piston rod 535, the two ends of the spring 536 being fixedly connected to the lower end of the round rod 532 and the round block on the piston rod 535, respectively.

[0040] During implementation, the round hole on the base is aligned with the positioning rod on the placement plate 525, and the lower end of the base is placed on the upper end of the placement plate 525. Then, the output end of the servo motor 524 is started to drive the threaded rod 523 to rotate through the coupling. Since the slider 522 and the threaded rod 523 are threadedly connected, the slider 522 can move to the right on the inner surface of the partition 51, thereby driving the base on the placement plate 525 to move.

[0041] Secondly, as the hollow rod 526 moves to the right, it drives the piston rod 535 on the inner surface of the round rod 532 to move to the right. Since the height of the guide rail 531 decreases from left to right, and the roller 537 at the lower end of the piston rod 535 is slidably connected to the guide rail 531, the piston rod 535 moves downward on the inner surface of the round rod 532. During the movement, it sucks air from inside the suction cup 533 through the connecting pipe 534, making the inside of the suction cup 533 a negative pressure state. This further fixes the substrate, prevents positional displacement, ensures accurate welding, improves welding quality and precision, reduces welding defects, and ensures the consistency and reliability of the welding results.

[0042] The aforementioned servo motor 524 is a mature drive technology and device in the existing technology. In this solution, its output end can drive the coupling to rotate in both directions, and can be locked in time after the set number of rotations is completed. Its internal structure, principle and connection method will not be described further.

[0043] For further details, please refer to [link / reference]. Figure 3 , Figure 5 and Figure 6In this embodiment, the welding powder solution mechanism 54 includes a brush plate 541 and a storage box 542, which are fixedly connected to the front part of the upper end of the partition plate 51. A cylinder 543 is fixedly connected to the front part of the lower end of the partition plate 51. A piston rod 544 is slidably connected to the inner surface of the cylinder 543. A spring 545 is sleeved on the outer surface of the piston rod 544. The two ends of the spring 545 are fixedly connected to the lower end of the cylinder 543 and the arc-shaped block on the piston rod 544, respectively. A connecting pipe 546 is fixedly connected to the upper part of the inner surface of the cylinder 543 and extends to the inner surface of the brush plate 541. The storage box 542 is connected to the cylinder 543 through a pipe. A one-way valve 547 is fixedly connected to the lower end of both the pipe connecting the storage box 542 and the cylinder 543 and the connecting pipe 546. A pressing block 5411 is fixedly connected to the outer surface of the round rod 532.

[0044] For further details, please refer to [link / reference]. Figure 3 and Figure 6 In this embodiment, a one-way bearing 548 is fixedly connected to the outer surface of the hollow rod 526, a gear 549 is fixedly connected to the outer surface of the one-way bearing 548, and a rack 5410 that meshes with the gear 549 is fixedly connected to the lower end of the partition plate 51.

[0045] During implementation, as the round rod 532 moves to the right, the extrusion block 5411 extrudes the arc-shaped block at the lower end of the piston rod 544, and the spring 545 is in a compressed state, causing the piston rod 544 to move upward on the inner surface of the cylinder 543, and extruding the solder powder solution in the cylinder 543 into the inner cavity of the brush plate 541 through the connecting pipe 546 and the one-way valve 547 on the connecting pipe 546, and into the brush between the brushes through several round holes, so that the brush can be completely coated with solder powder solution.

[0046] Secondly, during the process of the placement disk 525 driving the base to move to the right, when gear 549 and rack 5410 mesh with each other, gear 549 will drive the hollow rod 526 to rotate through one-way bearing 548, thereby causing the base on the placement disk 525 to rotate. This allows the edge welding point of the base to contact the brush during rotation. The brush, coated with welding powder solution, can evenly apply it to the welding point on the outer surface of the base. The uniform coating of welding powder solution on the base surface effectively improves the quality of the welding contact surface. The uniform application of welding powder solution by the brush can improve the lubrication effect during the welding process, reduce metal oxidation, and enhance the connection and stability of the welded part. The contact between the base and the brush during rotation further improves the uniformity of the welding area, thereby improving the welding strength and reliability between the base and the diamond cutting head, and avoiding welding defects caused by a lack of welding powder solution in some areas.

[0047] Furthermore, when the extrusion block 5411 moves away from the arc-shaped block at the lower end of the piston rod 544, the piston rod 544 will move downward on the inner surface of the cylinder 543 under the compressive reaction force of the spring 545, so that the solder powder solution in the storage box 542 will re-enter the inner cavity of the cylinder 543 through the pipe and the one-way valve 547.

[0048] The aforementioned one-way bearing 548 is a mature one-way rotating part and technology in the prior art. In this solution, it is used to make the bearing rotate in one direction and lock in the other direction. Its internal structure, principle and connection method will not be described further.

[0049] The two check valves 547 mentioned above are mature one-way control components in the prior art. In this solution, they are used to control the flow direction of the liquid and to ensure that the two check valves 547 control in opposite directions. Their internal structure, principle and connection method will not be described further.

[0050] For further details, please refer to [link / reference]. Figure 3 and Figure 7 In this embodiment, the positioning mechanism 55 includes a pressing disc 551 fixedly connected to the upper right side of the partition plate 51, a separating disc 552 slidably connected to the inner surface of the placement disc 525, and four fixing rods 553 fixedly connected to the lower end of the separating disc 552 in an annular pattern at equal intervals. Each of the four fixing rods 553 has a ball bearing 554 on its inner surface.

[0051] During the process, after the welding powder solution is applied to the substrate, the plate on the placement disk 525 will still move to the right. When the ball bearing 554 on the fixing rod 553 contacts the extrusion disk 551, the extrusion disk 551 will drive the partition disk 552 to slide upward on the inner surface of the placement disk 525 and gradually move to the set height. At this time, the partition plate on the partition disk 552 will automatically partition the substrate. Then, the operator can place the diamond cutter head on the upper end of the partition disk 552 and limit the position of the diamond cutter head through the partition plate. This allows the diamond cutter head to be precisely positioned on the substrate, avoiding welding defects or accuracy problems caused by positional deviations. This helps to improve the accuracy and stability of the welding, ensure the welding quality between the diamond cutter head and the substrate, reduce welding defects caused by improper positioning, and improve the overall welding effect.

[0052] For further details, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 8In this embodiment, the ejection mechanism 56 includes two ejection rods 561 that are symmetrically slidably connected to the inner surface of the placement plate 525. Springs 562 are sleeved on the outer surfaces of the two ejection rods 561. The two ends of the springs 562 are fixedly connected to the lower end of the placement plate 525 and the arc-shaped block on the ejection rods 561, respectively. The upper left part of the partition plate 51 is fixedly connected to the first extrusion plate 563 and the second extrusion plate 564, respectively.

[0053] During implementation, after the substrate and diamond cutting head are welded, they move to the left of the inner surface of the outer shell 1 via the placement mechanism 52. When the arc-shaped block at the lower end of the ejector rod 561 contacts the extrusion plate 1 563 and extrusion plate 2 564, the two ejector rods 561 slide upward on the inner surface of the placement plate 525 simultaneously, causing the spring 3 562 to be in a compressed state. Subsequently, the ejector rod 561 will push the welded substrate and diamond cutting head out of the positioning rod of the placement plate 525, avoiding errors or damage that may be caused by manual operation. Through precise ejection, it is ensured that the welded substrate and diamond cutting head can be safely and quickly removed, which facilitates subsequent processing, reduces manual intervention, improves work efficiency, and ensures that the welded parts are not damaged throughout the process, maintaining the stability of the welding quality.

[0054] The length of the extrusion plate 564 mentioned above is longer than that of the extrusion plate 563, so that the two diagonally distributed ejector rods 561 can move upward simultaneously.

[0055] Example 2: Based on Example 1, this example adds a pressing component 6 to press the substrate and diamond cutting head during the welding process and to rotate the substrate, thereby achieving the purpose of pressing the substrate and diamond cutting head and rotating the substrate during the welding process.

[0056] Specifically, in order to press down on the substrate and rotate the diamond cutting tip during the welding process, refer to... Figure 3 , Figure 9 and Figure 10 In this embodiment, the pressing component 6 includes a cylinder 61 fixedly connected to the upper right side of the inner surface of the outer shell 1, a fixing mechanism 62 is provided at the lower end of the cylinder 61, and a rotating mechanism 63 is provided at the lower end of the partition 51.

[0057] For further details, please refer to [link / reference]. Figure 3 and Figure 9 In this embodiment, the fixing mechanism 62 includes a connecting rod 621 fixedly connected to the lower end of the cylinder 61, and a pressing block 622 is fixedly connected to the lower end of the connecting rod 621.

[0058] For further details, please refer to [link / reference]. Figure 3 , Figure 9 and Figure 10In this embodiment, the rotating mechanism 63 includes two fixed blocks 631 fixedly connected to the lower right side of the partition plate 51. The inner surfaces of the two fixed blocks 631 are rotatably connected to a first locking rod 633. The rear part of the outer surface of the first locking rod 633 is fixedly connected to a second one-way bearing 634. The outer surface of the second one-way bearing 634 is fixedly connected to a second gear 635. The outer surface of the connecting rod 621 is fixedly connected to a second rack 632 that meshes with the second gear 635. The outer surface of the round rod 532 is fixedly connected to a fixed plate 636. The inner surface of the fixed plate 636 is rotatably connected to a second locking rod 637. The front part of the outer surface of the second locking rod 637 is fixedly connected to a third one-way bearing 638. The outer surfaces of the third one-way bearing 638 and the hollow rod 526 are jointly fixedly connected to a transmission mechanism 639.

[0059] During implementation, after the cutter head and the substrate are placed and before welding, the cylinder 61 is activated to drive the connecting rod 621 to move downward until the lower end of the pressing block 622 fixes the upper end of the diamond cutter head. Since the rack 2 632 and the gear 2 635 are meshed, the downward movement of the rack 2 632 will drive the gear 2 635 to rotate. Under the action of the one-way bearing 2 634, the gear 2 635 rotates freely and cannot drive the locking rod 1 633 to rotate.

[0060] Secondly, after one of the diamond cutting heads is welded, cylinder 61 drives connecting rod 621 to move upward, and the lower end of pressing block 622 moves away from the diamond cutting head. At this time, as rack 2 632 moves upward, it drives gear 2 635 to rotate. Under the locking action of one-way bearing 2 634, it drives locking rod 1 633 to rotate. When the base moves to the set position, the outer surface of locking rod 1 633 enters the inner surface of locking rod 2 637. The rotation of locking rod 1 633 will drive locking rod 2 637 to rotate, and under the action of one-way bearing 3 638, it will be transmitted through the transmission mechanism. 639 drives the hollow rod 526 to rotate, which in turn drives the substrate and diamond cutting head on the placement plate 525 to rotate at an angle. This allows for the replacement of unwelded diamond cutting heads, ensuring that each rotation is at a fixed angle. This enables automatic rotation and positioning of the substrate and diamond cutting head, ensuring that each diamond cutting head is correctly placed and avoiding poor welding due to improper positioning. Precise angle control improves welding quality, ensures a more stable weld connection between the diamond cutting head and the substrate, and enhances the overall reliability and consistency of the weld.

[0061] Furthermore, during the movement of the placement disc 525 to the right, the meshing of rack 5410 and gear 549 will drive the transmission mechanism 639 to rotate. However, under the action of the one-way bearing 638, the transmission mechanism 639, which is fixedly connected to the lever 637, will idle.

[0062] After the rack 2 632 and gear 2 635 are engaged, the gear 2 635 drives the rotation angle of the placement disk 525. This angle can be set according to the actual angle between the substrate and the diamond cutter head. The stroke of the rack 2 632 and gear 2 635 being engaged can drive the unwelded substrate and the diamond cutter head to rotate to the set position.

[0063] The rotation between the second locking rod 637 and the fixed plate 636, and between the first locking rod 633 and the fixed block 631, has a certain degree of damping.

[0064] The two one-way bearings 634 and 638 mentioned above are both mature one-way rotating parts and technologies in the prior art. In this solution, we utilize their function of being able to rotate in one direction and locking in the other direction. Their internal structure, principle and connection method will not be described further.

[0065] The transmission mechanism 639 mentioned above consists of two bevel gears.

[0066] Workflow: During use, the substrate is precisely positioned and fixed by the cooperation between the placement mechanism 52 and the adsorption mechanism 53. Then, during the movement, the welding powder solution mechanism 54 applies welding powder solution to the outer surface of the substrate welding area. When the substrate moves to the welding position, the positioning mechanism 55 limits the position of each diamond cutting head. Then, the substrate and diamond cutting head are replaced by the cooperation of the rotation mechanism 63 and the fixing mechanism 62. After welding, the ejection mechanism 56 automatically unloads the material.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
