Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a welding device for the production of diamond cutting tools. Background Technology

[0002] Typically, after prolonged use, the serrated edges of a circular saw blade wear down and become dull. Therefore, by welding diamond teeth onto the saw blade, the blade gains high wear resistance, allowing it to last longer. Figure 4 As shown, the cutting tool 34 is a cutting tool 34 after the diamond cutting teeth 33 are welded. The cutting tool 34 has an internal spline at its center and several mounting grooves 35 are opened on the periphery of the cutting tool 34. The diamond cutting teeth 33 are welded into the mounting grooves 35.

[0003] Currently, when welding diamond cutting teeth, each diamond cutting tooth needs to be welded into the mounting groove one by one. Since there are a large number of diamond cutting teeth, they need to be repeatedly picked up, placed, fixed and welded, resulting in low welding efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a welding device for diamond cutting tool production, thereby solving the problem of low welding efficiency mentioned in the background section.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A welding device for producing diamond cutting tools includes a chassis. A first slide is driven to move left and right on the chassis via a first left-right displacement mechanism. A second slide is driven to move back and forth on the first slide via a front-back displacement mechanism. A circular base is fixed on the second slide. A first positioning post is connected to the center of the base by screws. The periphery of the first positioning post has protruding external splines. Several circumferentially distributed positioning mechanisms are arranged around the periphery of the base. The positioning mechanism can press the diamond cutting teeth tightly onto the substrate; the chassis is connected to a frame with a front opening, the frame is equipped with a lifting mechanism, and a housing is connected to the lifting mechanism. A rotating column is rotatably connected to the bottom surface of the housing, and a drive mechanism for driving the rotating column to rotate is provided inside the housing. A U-shaped seat is connected to the lower end of the rotating column, and a second positioning column is connected to the bottom surface of one end of the U-shaped seat. The center of the second positioning column is aligned with the center of the rotating column. A second left-right displacement mechanism is installed on the U-shaped seat, and an L-shaped mounting bracket is connected to the second left-right displacement mechanism. A welding torch is installed on the mounting bracket.

[0007] Preferably, the first left and right displacement mechanism includes a first lead screw rotatably connected to the lower part of the frame via a rotary bearing, a first guide rail connected to the top surface of the chassis, and a first motor installed on one side of the frame. The first motor is drivenly connected to the first lead screw, and a first slide block is threadedly connected to the first lead screw and slidably connected to the first guide rail.

[0008] By controlling the first motor to work, the first lead screw can be rotated, which in turn can drive the first slide to move left and right along the first guide rail.

[0009] The front-to-back displacement mechanism includes bearing seats connected to the front and rear ends of the first slide, a second lead screw rotatably connected to the two bearing seats via a rotary bearing, a second guide rail mounted on the first slide and extending front-to-back, and a second motor mounted on the front side of the first slide. The second motor is drivenly connected to the second lead screw, the second slide is threadedly connected to the second lead screw, and the second slide is slidably connected to the second guide rail.

[0010] By controlling the second motor to rotate the second lead screw, the second slide can move back and forth along the second guide rail.

[0011] The second left and right displacement mechanism includes a third lead screw rotatably connected to the U-shaped seat via a rotary bearing, a guide rod connected to the U-shaped seat, and a third motor installed at one end of the U-shaped seat. The third motor is driven by the third lead screw, and the upper part of the mounting bracket is threadedly connected to the third lead screw, and the mounting bracket is slidably connected to the guide rod.

[0012] By controlling the third motor to rotate the third lead screw, the mounting bracket can move left and right, thereby adjusting the distance between the welding torch and the first positioning post.

[0013] Preferably, the positioning mechanism includes a support plate fixedly connected to the periphery of the chassis, a first cylinder installed on the outside of the support plate, an L-shaped mounting plate connected to the telescopic end of the first cylinder, a second cylinder installed on the mounting plate, and a pressure plate connected to the telescopic end of the second cylinder. The pressure plate is located below the mounting plate, and the extension of the first cylinder can drive the pressure plate to the top of the chassis.

[0014] The above technical solution involves placing the diamond cutting teeth in the mounting groove of the blade, then controlling the extension of the first cylinder to position the pressure plate above the diamond cutting teeth, and then controlling the extension of the second cylinder to lower the pressure plate, thereby pressing the diamond cutting teeth onto the blade. It should be noted that when the pressure plate is pressing the diamond cutting teeth, a welding position must be reserved to prevent it from affecting the welding of the welding torch.

[0015] Preferably, the lifting mechanism includes a third cylinder installed on the top of the frame and a slide rod slidably connected to the top of the frame, wherein the telescopic end of the third cylinder and the lower end of the slide rod are both connected to the housing.

[0019] Preferably, the first positioning post and the second positioning post are provided with mutually cooperating position sensors at their centers.

[0020] Through the above technical solution, and with the cooperation of the position sensor, the center of the second positioning post can be aligned with that of the first positioning post.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The inner spline of the cutting tool is fitted onto the first positioning post to prevent the cutting tool from rotating. The diamond cutting teeth are placed sequentially into the mounting groove of the cutting tool. According to the welding position of the diamond cutting teeth, the distance between the welding torch and the second positioning post is adjusted by the second left and right displacement mechanism to adapt to cutting tools of different diameters.

[0023] Diamond cutting teeth are welded onto the cutting blade using a welding torch. The rotating column is controlled by a drive mechanism, which in turn drives the U-shaped seat to rotate. This causes the welding torch to rotate around the second positioning column, allowing the diamond cutting teeth to be welded onto the cutting blade one by one, greatly improving welding efficiency.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1-4A welding device for producing diamond cutting tools includes a chassis 1. A first slide 2 is driven to the chassis 1 via a first left-right displacement mechanism, which drives the first slide 2 to move left and right. A second slide 3 is driven to the first slide 2 via a front-back displacement mechanism, which drives the second slide 3 to move back and forth. Specifically, the first left-right displacement mechanism includes a first lead screw 13 rotatably connected to the lower part of the frame via a rotary bearing, a first guide rail 14 connected to the top surface of the chassis, and a first motor 15 mounted on one side of the frame. The first motor 15 is driven to the first lead screw 13. The first slide 2 is threadedly connected to the first lead screw 13 and slidably connected to the first guide rail 14. The bottom surface of the first slide 2 has a first groove, through which it slidably connects to the first guide rail 14. The first slide 2 has a first threaded hole, through which it is threadedly connected to the first lead screw 13. The first motor 15 is controlled to operate, driving the first lead screw 13 to rotate. When the first lead screw 13 rotates, it drives the first slide 2 to move left and right along the first guide rail 14. The front-to-back displacement mechanism includes bearing seats 16 connected to the front and rear ends of the first slide, a second lead screw rotatably connected to the two bearing seats via a rotary bearing, a second guide rail 17 mounted on the first slide and extending front and back, and a second motor 18 mounted on the front side of the first slide. The second motor 18 is drively connected to the second lead screw, the second slide 3 is threadedly connected to the second lead screw, and the second slide 3 is slidably connected to the second guide rail 17. The bottom surface of the second slide 3 is provided with a second sliding groove, and it is slidably connected to the second guide rail 17 through the second sliding groove. The second slide 3 is provided with a second threaded hole, and it is threadedly connected to the second lead screw through the second threaded hole. Controlling the second motor 18 to operate, driving the second lead screw to rotate, can drive the second slide 3 to move back and forth along the second guide rail 17.

[0032] A circular base 4 is fixed on the second slide 3. A first positioning pin 5 is connected to the center of the base 4 by screws. The outer periphery of the first positioning pin 5 has a protruding external spline. Since the blade has an internal spline at its center, the blade 34 can be fixed by the external spline on the first positioning pin 5 to prevent it from rotating. In actual operation, a matching first positioning pin 5 can be selected according to the center hole and internal spline of the blade to fix different types of blades, improving adaptability.

[0033] The chassis 4 is provided with several circumferentially distributed positioning mechanisms on its periphery. Each positioning mechanism includes a support plate 22 fixedly connected to the periphery of the chassis, a first cylinder 23 mounted on the outside of the support plate, an L-shaped mounting plate 24 connected to the telescopic end of the first cylinder, a second cylinder 25 mounted on the mounting plate, and a pressure plate 26 connected to the telescopic end of the second cylinder. The pressure plate 26 is located below the mounting plate 24, and can be moved above the chassis 4 by extending the first cylinder 23. After the blade is fitted onto the first positioning post 5, the diamond cutting tooth is placed in the blade's mounting groove. Then, the first cylinder 23 is extended so that the pressure plate 26 is positioned above the diamond cutting tooth, with a small distance between the end face of the pressure plate 26 and the weld seam between the diamond cutting tooth and the blade, i.e., a pre-reserved welding position. Then, the second cylinder 25 is extended, causing the pressure plate 26 to descend, pressing the diamond cutting tooth onto the blade.

[0034] The chassis 1 is connected to a frame 6 with a front opening. A lifting mechanism is installed on the frame 6, and a housing 7 is connected to the lifting mechanism. The lifting mechanism includes a third cylinder 27 installed on the top of the frame and a slide rod 28 slidably connected to the top of the frame. The extension end of the third cylinder 27 and the lower end of the slide rod 28 are both connected to the housing 7. Controlling the extension of the third cylinder 27 can drive the housing 7 to descend, while the slide rod 28 makes the lifting and lowering of the housing 7 more stable.

[0035] The bottom surface of the housing 7 is rotatably connected to a rotating column 8. Inside the housing 7 is a drive mechanism that drives the rotating column 8 to rotate. The drive mechanism includes a fourth motor 29 installed inside the housing, a transmission shaft connected to the fourth motor via a coupling, a first gear 30 fixedly connected to the transmission shaft, and a second gear 31 fixedly connected to the rotating column. The first gear 30 and the second gear 31 mesh. When the fourth motor 29 is started, it drives the transmission shaft to rotate. Through the engagement of the first gear 30 and the second gear 31, the rotating column 8 is driven to rotate, thereby causing the U-shaped seat 9 to rotate around the rotating column 8.

[0036] The lower end of the rotating column 8 is connected to a U-shaped seat 9. A second positioning post 10 is connected to the bottom surface of one end of the U-shaped seat 9. The center of the second positioning post 10 is aligned with the center of the rotating column 8. A second left-right displacement mechanism is mounted on the U-shaped seat 9, and an L-shaped mounting bracket 11 is connected to the second left-right displacement mechanism. A welding torch 12 is mounted on the mounting bracket 11. The second left-right displacement mechanism includes a third lead screw 19 rotatably connected to the U-shaped seat via a rotary bearing, a guide rod 20 connected to the U-shaped seat, and a third motor 21 mounted at one end of the U-shaped seat. The third motor 21 is drive-connected to the third lead screw 19. The upper part of the mounting bracket 11 is threadedly connected to the third lead screw 19, and the mounting bracket 11 is slidably connected to the guide rod 20. Controlling the third motor 21 to rotate the third lead screw 19 causes the mounting bracket 11 to move left and right along the guide rod 20, thereby adjusting the distance between the welding torch 12 and the first positioning post 5 to accommodate blades of different diameters.

[0037] The working principle of this embodiment is as follows:

[0038] The inner spline of the blade 34 is fitted onto the outer spline of the first positioning post 5 to prevent the blade 34 from rotating. Then, the diamond cutting teeth are placed 33 times into the mounting groove 35 of the blade, and the diamond cutting teeth are pressed tightly onto the blade by the pressure plate 26. At the same time, a distance is left between the pressure plate 26 and the welding point to reserve the welding position. Then, the first motor 15 is started to drive the first slide 2 to move left and right to adjust the position of the first slide 2. The second motor 18 is started to drive the second slide 3 to move back and forth to adjust the position of the second slide 3 so that the first positioning post 5 is aligned with the second positioning post 10. Then, according to the blade... The diameter, which is the welding position of the diamond cutting teeth, is determined by starting the third motor 21, which drives the mounting frame 11 to move left and right, adjusting the distance between the welding torch 12 and the second positioning post 5, so that the trajectory of the welding torch 12 when it makes a circular motion around the second positioning post 10 is on the weld seam. Then, the third cylinder 27 is controlled to drive the housing 7 to descend, and the diamond cutting teeth are welded onto the blade through the welding torch. At the same time, the drive mechanism controls the rotating column 8 to rotate, driving the U-shaped seat 9 to rotate, so that the welding torch 12 rotates around the second positioning post 10 as the center, so that the diamond cutting teeth are welded onto the blade one by one, which greatly improves the welding efficiency.

[0039] Example 2

[0040] Based on Embodiment 1, the first positioning post 5 and the second positioning post 10 are provided with mutually cooperating position sensors 32 at their centers. The position sensors can be infrared receivers and infrared transmitters. An infrared transmitter can be set on the first positioning post 5, and a corresponding infrared receiver can be set on the second positioning post 10. Through the cooperation of the infrared transmitter and the infrared receiver, the center of the second positioning post can be aligned with that of the first positioning post, thereby improving the alignment accuracy.
