Description

A special machine for saw blade laser tooth trimming

Technical Field

The utility model belongs to the technical field of PCD saw blade processing, and in particular relates to a saw blade laser tooth trimming machine.

Background Art

PCD diamond saw blades, as a cutting tool, are widely used in cutting hard and brittle materials such as ceramics, wood boards, stones, concrete and refractory materials.

As shown in Figs. 1 and 4, the PCD diamond saw blade 1 comprises a saw blade body 11 and a plurality of saw teeth 12 evenly distributed on the outer circumference of the saw blade body 11. The saw blade body 11 is formed by stamping a steel plate and a mounting through hole (not shown in the figure) is opened in the center of the saw blade body 11. A diamond cutter head 13 is welded on the cutting surface of each saw tooth 12. When the saw blade 1 is processed and trimmed, the cutter head back angle surface 14, the cutter head side surface 15 on both sides and the cutter head cutting edge 16 of the diamond cutter head 13 need to be trimmed, wherein the cutter head cutting edge 16 refers to the intersection of the cutter head back angle surface 14, the cutter head side surface 15 on both sides and the cutter head front angle surface 17.

Since the diamond bit 13 is made of diamond material, it has high hardness and high wear resistance, and the general processing method cannot process PCD saw blades. Therefore, the existing technology mainly uses grinding or electric spark processing to process PCD saw blades. The efficiency of grinding or electric spark processing is too low, and the processing accuracy is poor. There are tiny cracks on the processed surface, and the product quality is not guaranteed. At the same time, grinding requires a large amount of cutting fluid, and the pollution of cutting fluid is extremely difficult to deal with. Secondly, the PCD layer made of diamond material has poor conductivity or even no conductivity, which leads to low efficiency and high processing cost of electric spark processing.

The Chinese invention patent with application number 202211415810.4 discloses a method for processing PCD saw blades using laser grinding, which mainly includes sawtooth rough machining process and sawtooth finishing process, and the sawtooth rough machining process includes sawtooth back angle surface machining process and sawtooth side surface machining process on both sides. The present invention processes the saw teeth of the PCD saw blade in three separate processes, wherein the sawtooth back angle surface and the sawtooth side surface can be processed simultaneously by two laser processing equipment, or the sawtooth back angle surface and the sawtooth side surface can be processed separately by one laser processing equipment in no particular order, and finally the sawtooth cutting edge is finished, and the sawtooth cutting edge with a circular arc structure is ground into a sharp pointed structure. The present invention is mainly used for laser processing of sawtooth back angle surfaces, sawtooth side surfaces and sawtooth cutting edges on saw blades.

In the prior art, although the tooth trimming processing of the diamond cutter head 13 can be achieved by laser, the following technical problems still exist: 1. The existing laser processing equipment cannot directly process the cutter head back angle surface 14, cutter head side surface 15 and cutter head cutting edge 16 of the diamond cutter head 13, and multiple devices need to be used for processing one by one; 2. The existing laser processing equipment cannot be applied to the processing of PCD diamond saw blades of various specifications and sizes, and its versatility is poor; 3. The existing laser processing equipment has a low level of automation when performing laser processing on the diamond cutter head 13 through a laser galvanometer.

In this embodiment, as shown in FIGS. 2 and 3 , the X direction is along the horizontal length direction of the workbench 2 , the Y direction is along the horizontal width direction of the workbench 2 , and the Z direction is the vertical direction, so the X direction, the Y direction and the Z direction are perpendicular to each other.

As shown in Fig. 6, the saw blade mounting mechanism 3 includes a saw blade X-direction sliding module arranged on the workbench 2 along the X-direction, and a clamp 33 fixedly connected to the moving part of the saw blade X-direction sliding module. Specifically, the saw blade X-direction sliding module is a saw blade X-direction lead screw linear module 32 driven by a saw blade X-direction servo motor 31.

As shown in FIG. 7 , the fixture 33 includes a fixed plate 331 fixedly connected to the moving part of the screw linear module 32 by bolts, a fixed plate through hole 3311 is opened in the middle of the fixed plate 331, a bearing seat 332 is fixedly embedded in the fixed plate through hole 3311 of the fixed plate 331 by bolts, and a rotating bearing 333 is fixedly embedded in the bearing seat 332. In this embodiment, the rotating bearing 333 is preferably a 6908ZZ deep groove ball bearing, a rotating shaft 334 is fixedly penetrated in the inner ring of the rotating bearing 333, and two thrust rings 335 are fixedly sleeved on the rotating shaft 334 in the fixed plate through hole 3311, and the thrust ring 335 abuts against the inner ring of the rotating bearing 333.

The saw blade 1 is sleeved on the rotating shaft 334 and fixed between the locking ring 336 and the bearing seat 332 .

Furthermore, in order to further improve the locking force of the saw blade 1, a washer 337 is sleeved on the rotating shaft 334 between the locking ring 336 and the boss 3341, and the saw blade 1 is fixed between the washer 337 and the boss 3341. Thus, the above structure can facilitate the rapid disassembly and assembly of the saw blade 1.

As shown in FIG. 3 , the saw blade clamping mechanism 4 includes a clamping cylinder 41 fixedly connected to the workbench 2 at one end of the saw blade X-axis screw linear module 32 by bolts, and a clamping head 42 fixedly sleeved on the guide rod of the clamping cylinder 41.

In this embodiment, in order to facilitate the rapid clamping of the saw blade 1, the saw blade clamping mechanism 4 is relatively provided with two groups. When the saw blade 1 needs to be clamped, the guide rod of the clamping cylinder 41 extends, so that the saw blade 1 is clamped between the two clamping heads 42.

The paddle frame 53 includes a paddle sleeve 531 fixedly sleeved on the output shaft of the paddle motor 52, a paddle plate 532 fixedly connected to the end of the paddle sleeve 531 by bolts at one end, and a paddle post 533 fixedly embedded at the other end of the paddle plate 532. Thus, the paddle motor 52 drives the paddle post 533 to rotate with the output shaft of the paddle motor 52 as the axis, so that the paddle post 533 is inserted into the gap between the two saw teeth 12 and the saw blade 1 is paddled to rotate, so as to process each diamond cutter head 13 thereof one by one. In this embodiment, in order to shift saw blades 1 of different models and sizes and improve the shifting accuracy, a shifting plate X-direction sliding module is fixedly connected to the workbench 2 along the X-direction by bolts, and the bracket 51 is fixedly connected to the moving part of the shifting plate X-direction sliding module by bolts. Specifically, the shifting plate X-direction sliding module is a shifting plate X-direction lead screw linear module 55 driven by a shifting plate X-direction servo motor 54.

As shown in Figure 8, in order to position and preliminarily fix the saw blade 1 before the saw blade 1 is clamped by the saw blade clamping mechanism 4, and to avoid errors in the rotation angle of the saw blade 1 when it is turned by the paddle mechanism 5, in this embodiment, the utility model also includes a baffle mechanism 7 arranged opposite to the paddle mechanism 5, the baffle mechanism 7 includes a baffle support 71 fixedly connected to the workbench 2 by bolts, a baffle cylinder 72 fixedly connected to the baffle support 71 along the Y direction, and a baffle frame 73 fixedly connected to the guide rod of the baffle cylinder 72.

Specifically, the baffle frame 73 includes a baffle plate 731 which is vertically fixed to the guide rod of the baffle cylinder 72 by bolts along the Y direction, and a bent plate 732 which is integrally formed with the baffle plate 731 on the upper end surface thereof and bent toward between the two saw teeth 12. The bending angle of the bent plate 732 relative to the baffle plate 731 matches the inclination angle of the saw teeth 12, that is, the bent plate 732 can slide in and out of the gap between the two saw teeth 12. Therefore, by providing the bent plate 732, it is also possible to prevent the processed diamond bit 13 below the bent plate 732 from being misprocessed or contaminated to a certain extent.

Furthermore, a slide rail 74 is vertically fixedly connected to the baffle support 71 by bolts, a slider 75 is slidably arranged on the slide rail 74, the baffle cylinder 72 is fixedly connected to the slider 75 by bolts, and a locking bolt 76 is threadedly connected in the slider 75 and abuts against the slide rail 74 to lock the slider 75 in a certain position. Therefore, by adjusting the height of the slider 75, the height of the baffle cylinder 72 and the baffle frame 73 can be adjusted to adapt to saw blades 1 of different sizes.

As shown in FIG. 10 , the laser galvanometer module 6 includes a support 61 fixedly connected to the workbench 2 by bolts, a laser Z-direction sliding module 62 vertically fixedly installed on the support 61, a laser Y-direction sliding module 63 fixedly connected to the moving part of the laser Z-direction sliding module 62 by bolts, a rotating module 64 fixedly connected to the moving part of the laser Y-direction sliding module 63 by bolts, and a laser galvanometer 65 fixedly connected to the rotating part of the rotating module 64 by bolts.

Therefore, when the diamond head 13 of the saw blade 1 is laser cut, the saw blade 1 is fixed on the fixture 33 and the controller controls the saw blade mounting mechanism 3, the saw blade clamping mechanism 4, the paddle mechanism 5 and the laser galvanometer module 6 to process the saw blade 1.

Specifically, the working process of the embodiment of the utility model is as follows:

The components are installed according to the structural description of the above embodiment, the saw blade 1 is sleeved on the rotating shaft 334, and the saw blade 1 is fixedly installed on the saw blade installation mechanism 3 through the gasket 337 and the locking ring 336, as shown in FIG2; then the saw blade X-direction servo motor 31 drives the saw blade X-direction lead screw linear module 32 to move the saw blade 1 to a suitable position, and the paddle X-direction servo motor 54 drives the paddle X-direction lead screw linear module 55 to move the paddle motor 52 and the paddle frame 53 to a suitable position, and the height of the baffle cylinder 72 and the baffle frame 73 are adjusted, that is, when the components are in the above position, the clamping heads 42 of the two saw blade clamping mechanisms 4 can clamp the saw blade 1, the paddle frame 53 can pry the saw teeth 12, and the bending plate 732 can pass through the gap between the two saw teeth 12;

The laser galvanometer 65 is moved to a suitable position through the laser Z-direction sliding module 62, the laser Y-direction sliding module 63 and the rotating module 64, so as to perform laser cutting processing on the processing surfaces such as the back angle surface 14, the side surface 15 and the cutting edge 16 of the diamond cutter head 13. The specific processing method and processing principle are the existing technology, such as the Chinese invention patent with application number 202211415810.4 and invention name "A method for processing PCD saw blades by laser grinding" described in the background technology can be selected;

After the processing of the diamond cutter head 13 on one saw tooth 12 is completed, the guide rod of the clamping cylinder 41 is retracted to make the clamping head 42 disengage from the saw blade 1, and the guide rod of the baffle cylinder 72 is retracted to make the bending plate 732 disengage from between the two saw teeth 12, and the paddle motor 52 drives the paddle frame 53 to rotate so that the paddle column 533 drives the saw blade 1 to rotate an angle of a saw tooth 12. During this process, the paddle X-direction servo motor 54 can drive the paddle X-direction lead screw linear module 55 to drive the paddle motor 52 to move, so that the paddle 1 can be more accurately moved; then the guide rod of the baffle cylinder 72 is extended, so that the bending plate 732 is re-inserted between the two new saw teeth 12 to position and preliminarily fix the saw blade 1, and the guide rod of the clamping cylinder 41 is extended so that the clamping head 42 clamps the saw blade 1, and then the laser galvanometer 65 processes the diamond cutter head 13 on the next saw tooth 12; then the above process is repeated to achieve the processing of all diamond cutter heads 13.

The connection relationship and control logic between the above-mentioned control display 21 and each component are for automated operation to improve production efficiency. Of course, manual control and operation can also be performed. The connection relationship and control principle between the above-mentioned controller and each component are prior arts and will not be repeated here.
