[0003] Currently, before manufacturing the high-precision diamond saw blade, it is necessary to optimize the distribution and geometric shape of the cutting heads on the saw blade; during the manufacturing process, it is necessary to evenly draw positioning points on the circumference of the saw blade substrate, and then perform laser welding; laser welding can achieve a high-strength connection between the cutting head and the saw blade substrate; after welding, through edge opening, grinding and polishing, and painting, a high-precision diamond saw blade with high strength and uniform cutting head distribution can be formed.

[0004] Regarding the above-mentioned high-precision diamond saw blade manufacturing process, in the current actual production process, since the welding positioning point position of the laser welding head is fixed, during the welding process, it is necessary for workers to continuously adjust the welding interval on the outer circumference of the saw blade substrate, and at the same time align the cutting head in the corresponding welding interval with the saw blade substrate before welding.

By turning the adjusting screw 564 , the adjusting screw 564 can be advanced or withdrawn, thereby adjusting the sliding position of the support rod 562 and adjusting the amplitude of the tensioning transmission chain 55 in the arched abutment groove 561 .

[0028] In order to improve the transmission stability of the transmission chain 55 , a chain support 57 is further installed on the other side of the transmission chain 55 corresponding to the bow-shaped tensioning assembly 56 .

[0029] Combination Figure 5 The chain support 57 includes a fixing portion 571, a guide portion 572 and a clamping edge 573. The fixing portion 571 is used to be fixed on the mounting base 1, and the upper surface of the fixing portion 571 is arranged horizontally; there are two guide portions 572, which are symmetrically fixed on the upper surface of the fixing portion 571; there are two clamping edges 573, which are respectively fixed on the top of the two guide portions 572, and a gap is left between the two clamping edges 573 and the two guide portions 572 for the transmission chain 55 to pass through. One or more chain supports 57 can be provided according to the length of the transmission chain 55, mainly to support and guide the transmission chain 55, reduce the shaking of the transmission chain 55 during transmission, especially when starting or stopping, and maintain the stability of transmission.

[0030] Reference Figure 6 A clamping stopper 6 is provided between the rotating shaft 531 and the saw blade base 91 to limit the positions of the two. Figure 7, a plug hole 5311 that matches the clamping and limiting member 6 is provided at the upper end of the rotating shaft 531 from top to bottom. The cross-section of the plug hole 5311 is C-shaped. A positioning notch 9111 is provided at the position of the mounting hole 911 on the saw blade base body 91. The positioning notch 9111 can also be used to cooperate with a key when being mounted on the rotating shaft later; the clamping and limiting member 6 includes a guiding column 61 for being inserted into the plug hole 5311, a clamping head 63 for being inserted into the positioning notch 9111, and a connecting column 62 with one end connected to the guiding column 61 and the other end connected to the clamping head 63. The central axes of the guiding column 61, the clamping head 63, and the connecting column 62 coincide, and the diameter of the connecting column 62 is smaller than the diameters of the guiding column 61 and the clamping head 63.

[0031] The implementation principle of the first embodiment of this application is as follows. Refer to Figures 1 - 7 , when welding the saw blade base body 91 and the cutting head 92, first sleeved the mounting hole 911 of the saw blade base body 91 on the rotating shaft 531, slowly and steadily place the saw blade base body 91 on the rotating support plate 41, and then snap the clamping and limiting member 6 into the plug hole 5311 and the positioning notch 9111; then place the first cutting head 92 at the position corresponding to the laser welding head 3 on the annular outer frame 42. The welding gap between the cutting head 92 and the saw blade base body 91 corresponds to the position of the laser welding head upwards and the avoidance interval 43 downwards; then turn on the laser welding head 3 to weld the first cutting head 92. The welding does not need to be completely welded, only need to weld a point first for pre-fixation; after the pre-fixation of the first cutting head 92 is completed, turn on the rotation driving mechanism 5, drive intermittently, drive the saw blade base body 91 to rotate a certain angle, and then perform the pre-fixation welding of the second cutting head 92; then drive intermittently to perform the pre-fixation welding of the third cutting head 92. According to the above sequence, the pre-fixation of all cutting heads 92 can be completed; after the pre-fixation of all cutting heads 92 is completed, the rotation driving mechanism 5 drives continuously, drives the saw blade base body 91 and all cutting heads 92 to rotate at a certain speed, and during the process, the laser welding head 3 performs the final welding fixation on the saw blade base body 91 and all cutting heads 92. Compared with the previous welding process, in the welding process of this application, the welding area on the outer periphery of the saw blade base body 91 can be adjusted by relying on the rotation driving mechanism 5 and the reference rotating table 4, and it is not necessary for the staff to continuously adjust by themselves; at the same time, because there is a rotating shaft 531 to calibrate the position of the saw blade base body 91 and an annular outer frame 42 to calibrate the position of the cutting head 92, the difficulty of aligning the cutting head 92 with the saw blade base body 91 is reduced; furthermore, in this application, the cutting head 92 can be pre-fixed first and then continuously welded, which reduces the welding difficulty and improves the welding efficiency; furthermore, the setting of the avoidance interval 43 enables the welding position of the cutting head 92 and the saw blade base body 91 to dissipate heat sufficiently, which is conducive to forming a more stable welding structure between the two, and also protects the rotating support plate 41 and the annular outer frame 42. Embodiment Two

[0032] A high-precision diamond saw blade production device, referring to Figure 8 , the difference between this embodiment and the first embodiment is that sliding seats 221 are arranged at intervals along the length direction of the lower surface of the horizontal section 22. A slide rail 222 is slidably connected among the plurality of sliding seats 221. The length direction of the slide rail 222 coincides with the length direction of the horizontal section 22. A set screw 223 for positioning the sliding position of the slide rail 222 is threadedly connected to the side wall of one of the sliding seats 221, and the end of the set screw 223 can abut against the slide rail 222; the laser welding head 3 is installed on the slide rail 222.

[0033] Through the above settings, the laser welding head 3 can be adjusted within a small range, and thus high-precision diamond saw blades 9 of the same type with small size differences can be processed. Embodiment Three

[0034] A high-precision diamond saw blade production device, referring to Figure 1 , Figure 2 , the difference between this embodiment and the first embodiment is that a vertical fixing mechanism 7 for fixing the saw blade base 91 is further arranged at a position where the horizontal section 22 is close to above the workbench 12. The vertical fixing mechanism 7 includes a vertical driving member 71, a rotating connecting rod 8272 and a pressing ring 73. The vertical driving member 71 is installed on the horizontal section 22 and the output end is arranged vertically downward. The central axis of the output end of the vertical driving member 71 coincides with the central axis of the rotating support plate 41. The vertical driving member 71 can adopt a cylinder, an oil cylinder and an electric push rod; the rotating connecting rod 8272 is arranged horizontally and is rotatably connected to the lower part of the output end of the vertical driving member 71; the pressing ring 73 is annular, arranged horizontally, and the central axis coincides with the central axis of the rotating support plate 41. The pressing ring 73 is fixedly connected to the lower part of the rotating connecting rod 8272.

[0035] Through the above settings, after the pre-fixing of the welding of the tool head 92 is completed, the saw blade base 91 can be first pressed and fixed by the vertical fixing mechanism 7, and then the rotation driving mechanism 5 is started to make the saw blade base 91 and all the tool heads 92 rotate. The laser welding head 3 performs the final welding and fixing on the saw blade base 91 and all the tool heads 92. Because of the pressing and fixing effect of the vertical fixing mechanism 7 to a certain extent, the saw blade base 91 can better maintain a stable state during the process, and the welding quality is better, which is more suitable for workpieces with a relatively large area of the saw blade base 91. Embodiment Four

[0036] A high-precision diamond saw blade production device, referring to Figure 9The difference between this embodiment and the first embodiment is that a cutter head 92 fixing mechanism 8 for fixing the cutter head 92 is further installed at the position corresponding to the cutter head 92 welding machine on the mounting base 1, and a clearance window 121 for the cutter head 92 fixing mechanism 8 to extend is provided on the workbench 12. When the cutter head 92 is pre-fixed for welding, the cutter head 92 fixing mechanism 8 can fix the cutter head 92, reduce the displacement of the cutter head 92 due to the welding airflow or other external factors, and thus improve the welding accuracy.

[0037] Specific, combined Figure 10 , Figure 11 The tool head 92 fixing mechanism 8 includes a telescopic member 81, a connecting rod 82 and a pressing plate 83. The telescopic member 81 can be a pneumatic rod, a hydraulic rod or an electric push rod. The telescopic member 81 is located in the cavity 11 and the lower end is rotatably connected to the mounting base 1, and the upper end of the telescopic member 81 is the output end; one end of the pressing plate 83 is rotatably connected to the upper end of the telescopic member 81 and the other end extends above the position of the tool head 92; the upper end of the connecting rod 82 is rotatably connected to the middle part of the pressing plate 83 and the lower end is rotatably connected to the side wall of the make way window 121 on the workbench 12; the distance between the upper end of the connecting rod 82 and the upper end of the telescopic member 81 is smaller than the distance between the upper end of the connecting rod 82 and the end of the pressing plate 83 close to the tool head 92.

[0038] Through the above arrangement, when the telescopic member 81 is in the extended state, the end of the pressing plate 83 close to the cutter head 92 presses on the cutter head 92, so that the cutter head 92 is stably placed on the annular outer frame 42 and remains stable during the welding process; when the current cutter head 92 is pre-fixed for welding, the telescopic member 81 enters the retracted state, and the end of the pressing plate 83 close to the cutter head 92 is lifted upward to release the fixation of the cutter head 92. The fixation and release of the cutter head 92 are relatively convenient in the whole process, and the fixation effect of the cutter head 92 is also relatively good. Embodiment 5

[0039] A high-precision diamond saw blade production device, referring to Figure 12 , Figure 13, the difference between this embodiment and the fourth embodiment lies in the different structures and fixing methods of the tool head 92 fixing mechanism 8. Specifically, the tool head 92 fixing mechanism 8 includes a telescopic member 81, a clamping block 84, a single-sided inclined block 85, and a guide block 86. The telescopic member 81 is vertically fixed on the installation base 1, and the upper end is the output end; the single-sided inclined block 85 is fixed to the upper end of the telescopic member 81. On the side of the single-sided inclined block 85 facing the tool head 92, there is an inclined surface, and the direction of the inclined surface is that the upper side is close to the tool head 92 and the lower side is far from the tool head 92; the clamping block 84 is slidably connected to the inclined surface of the single-sided inclined block 85, and the two are connected through the structure of a dovetail groove and a dovetail block; on the workbench 12, a relief window 121 is opened for the clamping block 84, the single-sided inclined block 85, and the guide block 86 to protrude. At the same time, at a position close to the tool head 92 in the relief window 121, a movement space 1211 is opened for the clamping block 84 to move in the direction approaching the tool head 92; the movement space 1211 communicates with the relief window 121 and the other side is close to the edge of the annular outer frame 42, and the edge of the tool head 92 slightly exceeds the edge of the annular outer frame 42; the guide block 86 is fixedly connected to the installation base 1 by bolts. The guide block 86 is located on the side of the single-sided inclined block 85 away from the inclined surface, and the single-sided inclined block 85 is slidably connected to the guide block 86, and the two are connected through the structure of a dovetail groove and a dovetail block. The lower edge of the clamping block 84 supports on the outer shell of the telescopic member 81, and the upper surface of the outer shell of the telescopic member 81 corresponding to the clamping block 84 is a plane, providing support for the sliding of the clamping block 84.

[0040] Through the above settings, when the telescopic member 81 is in the retracted state, the single-sided inclined block 85 moves downward, and then the clamping block 84 moves in the direction approaching the tool head 92, pressing the tool head 92 against the saw blade substrate 91 to keep the tool head 92 stable during the welding process; when the welding pre-fixing of the current tool head 92 is completed, the telescopic member 81 enters the extended state, the single-sided inclined block 85 moves upward, and then the clamping block 84 moves in the direction away from the tool head 92 to release the fixation of the tool head 92. The fixation and release of the tool head 92 are both relatively convenient during the whole process, and the fixation effect on the tool head 92 is also good.

[0041] The production process of the high-precision diamond saw blade 9 in this application is as follows: First, before manufacturing the high-precision diamond saw blade 9, it is necessary to optimize the distribution and geometric shape of the cutting heads 92 on the saw blade; Second, during the processing and manufacturing process, it is necessary to evenly draw positioning points on the circumference of the saw blade substrate 91; Then, laser welding is carried out. During laser welding, first, the cutting head 92 is fixed by the cutting head 92 fixing mechanism 8, and then the laser welding head 3 is turned on to weld the first cutting head 92. The welding does not need to be completely welded, only a point needs to be welded first for pre-fixing; After the pre-fixing of the first cutting head 92 is completed, the rotation drive mechanism 5 is turned on, and intermittent transmission is carried out to drive the saw blade substrate 91 to rotate by a certain angle, and then the pre-fixing of the second cutting head 92 is carried out; When the pre-fixing of the cutting head 92 welding is completed, the saw blade substrate 91 can be pressed and fixed by the vertical fixing mechanism 7 first, and then the rotation drive mechanism 5 is turned on to make the saw blade substrate 91 and all the cutting heads 92 rotate, and the laser welding head 3 performs the final welding and fixing of the saw blade substrate 91 and all the cutting heads 92; After welding, through edge opening, grinding and polishing, and painting, a high-precision diamond saw blade 9 with high strength and uniform distribution of cutting heads 92 can be formed.
