Description

Technical Field

[0001] The utility model relates to the technical field of diamond saw blade processing, in particular to a diamond disc laser cutting machine. Background Art

[0002] The diamond teeth of circular saw blades are mainly ground by electrospark machining. However, due to the poor contour of electrospark machining and the presence of tiny chipping, the quality of diamond teeth machining is difficult to guarantee. In addition, the conductivity of the diamond layer of diamond teeth is poor, so the efficiency of electrospark machining is low.

[0003] To solve this problem, the applicant applied for a utility model patent entitled "A laser cutting processing device for a saw blade substrate" and publication number "CN219703833U" on March 2, 2023, which discloses a laser cutting processing device for a saw blade substrate, including a laser cutting module, a frame, and a saw blade substrate adjustment module and a laser adjustment module arranged on the frame, and also includes a laser swing mechanism, wherein the laser cutting module is arranged on the laser swing mechanism through the laser swing mechanism, and is driven by the laser swing mechanism to swing relative to the saw blade substrate adjustment mechanism to realize the processing of the diamond saw teeth to form a cutting edge. This is because when producing circular saw blades, it is necessary to first divide the diamond disc into a number of square diamond particles, and then weld the diamond particles to the circumference of the saw blade substrate to form diamond saw teeth, and then use laser cutting processing equipment to process the diamond saw teeth into a certain angle to form a cutting edge, which is convenient for the tool to cut the material. In order to improve production efficiency, it is necessary to develop a device that can process diamond wafers and divide them into diamond particles with inclined surfaces, so as to save the time of subsequent laser processing or grinding of the cutting edge, thereby increasing production capacity.

[0023] A rotating shaft is provided on the fixed plate 7, and the angle adjustment plate 8 is arranged on the rotating shaft through a bearing, so that the angle adjustment plate 8 can be rotatably arranged on the fixed plate 7. In other embodiments, an axial hole can also be provided in the middle of the angle adjustment plate 8, and a bolt can be passed through the axial hole to be fixed to the fixed plate 7, so that the angle adjustment plate 8 can be rotatably connected to the fixed plate 7, and the installation is simple and convenient.

[0024] An arc-shaped adjustment groove 81 is provided on the angle adjustment plate 8, and a locking screw 82 adapted to the arc-shaped adjustment groove 81 is provided on the fixed plate 7. Specifically, a screw hole adapted to the locking screw 82 is provided on the fixed plate 7, and the locking screw 82 passes through the arc-shaped adjustment groove 81 and is screwed into the screw hole. Preferably, the number of the arc-shaped adjustment grooves 81 is two, and the two arc-shaped adjustment grooves 81 are arranged concentrically, which has a good angle positioning effect and is not easy to move. The fiber laser cutting head 2 is arranged on the angle adjustment plate 8. The lens module 10 is arranged on one side of the fixed plate 7 for visual positioning.

[0025] The fixing fixture 9 is arranged on the workbench 1 through the Y-axis moving module 4, and is driven by the Y-axis moving module 4 to reciprocate along the Y-axis direction. Specifically, the fixing fixture 9 includes a base 91, a bracket 92 and a clamping plate 93. The bracket 92 is arranged on the base 91, and an opening 921 is arranged in the middle. Two clamping plates 93 are symmetrically arranged on both sides of the opening 921, and can move closer or apart relative to each other to achieve clamping and loosening of the diamond disc. Specifically, a long hole 931 is arranged on the clamping plate 93, and an adjusting screw 932 adapted to the long hole 931 is arranged on the bracket 92. By adjusting the position of the screw 932 in the long hole 931, the relative position of the clamping plate 93 can be adjusted, so as to adapt to diamond discs of different sizes, thereby improving the versatility of the equipment. Preferably, an arc-shaped clamping opening 933 is arranged at one end of the two clamping plates 93 that are arranged opposite to each other, so as to better adapt to the shape of the diamond disc and provide a more stable clamping effect.

In this way, the laser beam emitted by the fiber laser cutting head 2 is at a certain tilt angle with the diamond disc. Therefore, when the diamond disc 11 is laser cut, diamond particles with an inclined surface at a certain tilt angle can be directly cut out. The diamond particles are generally parallelograms, and the inclined surface can be used to form a cutting edge, thereby saving the time of grinding the cutting edge, shortening the production cycle, and improving efficiency.
