DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment 1: like Figure 1 , 2As shown in Figures 3 and 4, a saw blade body laser circular plate cutting profile tooling includes a fixed base plate 1, a center positioning shaft 2 is detachably connected to the fixed base plate 1, the center positioning shaft 2 is engaged with the circular plate 3, and a plurality of magnetic columns 4 are connected to the fixed base plate 1, and the magnetic columns 4 are arranged along the circumferential direction of the center positioning shaft 2. The center positioning shaft 2 includes a connecting spindle 21, the connecting spindle 21 is detachably connected to the fixed base plate 1, and a positioning protrusion is connected to the side of the connecting spindle 21 away from the fixed base plate 1. The connecting spindle 21 includes a lower column 23 and a middle column 24, the lower column 23 is connected to the fixed base plate 1, the middle column 24 is arranged on the side of the lower column 23 away from the fixed base plate 1, the cross-sectional size of the middle column 24 is larger than the cross-sectional size of the lower column 23, and a wrench bayonet 25 is arranged on the middle column 24. The positioning protrusion 22 includes an upper surface 224 away from the side of the center positioning shaft 2, and a rotating opening 223 is arranged on the upper surface 224. The magnetic column 4 includes a support surface 41, the center positioning shaft 2 includes a connecting spindle 21, the center positioning shaft 2 includes a positioning protrusion arranged on the side of the connecting spindle 21 away from the fixed base plate 1, the positioning protrusion includes an upper surface 224 away from the side of the connecting spindle 21, the connecting spindle 21 includes a cutting surface 211 close to the side of the positioning protrusion, and the support surface 41 is located between the upper surface 224 and the cutting surface 211. The magnetic column 4 includes a fixed column 42, the fixed column 42 is connected to the fixed base plate 1, and the fixed column 42 is detachably connected to a magnetic unit 43 on the side away from the fixed base plate 1. The magnetic unit 43 is an electromagnetic control unit.

[0026] The assembly and working process of the saw blade body laser circular plate cutting profile tooling in this embodiment is as follows: In this embodiment, a fixed base plate 1 is arranged at the bottom, wherein the fixed base plate 1 is circular, and the fixed base plate 1 is respectively connected with a center positioning shaft 2 arranged in the middle position and a magnetic suction column 4 arranged around the center positioning shaft 2, wherein the center positioning shaft 2 in this embodiment includes a lower column 23, a middle column 24 and a positioning protrusion, wherein the lower column 23 is connected to the fixed base plate 1, and a screw protrusion is arranged on the side of the lower column 23 close to the fixed base plate 1, which is threadedly connected to the threaded hole on the fixed base plate 1. In this embodiment, a middle column 24 is arranged above the lower column 23, and the cross-sectional dimension of the middle column 24 is larger than the cross-sectional dimension of the lower column 23. Furthermore, in this embodiment, a notch is processed on both sides of the middle column 24 to form a wrench socket 25. During use, the wrench socket 25 can be clamped by a wrench and then rotated to connect the lower column 23 with the fixed base plate 1. Since the cross-sectional dimension of the middle column 24 is larger than the cross-sectional dimension of the lower column 23, the compressive resistance of the middle column 24 is higher, and it is more convenient to clamp the wrench socket 25 on the middle column 24 with a wrench.

[0027] Furthermore, in the present embodiment, a positioning protrusion is provided above the middle column 24, and the cross-sectional size of the positioning protrusion is smaller than that of the middle column 24 and the lower column 23. During use, the positioning protrusion needs to be connected with the center processing hole 31 on the circular plate 3 to position the circular plate 3, and it is necessary to set the size of the positioning protrusion and leave a placement gap 6 between the center processing hole 31 to facilitate the picking up of the circular plate 3. At the same time, since the center processing hole 31 also needs to be processed in the subsequent laser cutting process, a certain gap is left between the center of gravity processing hole and the positioning protrusion to avoid damage to the positioning protrusion during the laser cutting process of the center processing hole 31.

[0028] Furthermore, in this embodiment, a detachably connected magnetic unit 43 is provided on the magnetic column 4, and the magnetic unit 43 is connected to the fixed base plate 1 through the fixed column 42, wherein the fixed column 42 and the fixed base plate 1 are fixedly connected, and since the magnetic unit 43 is detachably connected to the fixed column 42, magnetic units 43 of different specifications can be freely replaced, thereby changing the processing height of the circular plate 3. The magnetic unit 43 includes a supporting surface 41 for supporting the circular plate 3, wherein the supporting surface 41 is in contact with the circular plate 3, and an upper surface 224 located on the positioning protrusion is provided on the central positioning shaft 2, and a cutting surface 211 is provided on the side of the middle column 24 close to the positioning protrusion. In the vertical direction, the supporting surface 41 is located between the upper surface 224 and the cutting surface 211. Therefore, when the circular plate 3 is placed, the central processing hole 31 on the circular plate 3 will pass through the positioning protrusion, and then the circular plate 3 will be in contact with the supporting surface 41. Since the circular plate 3 is in contact with the supporting surface 41, the circular plate 3 will not continue to move downward to abut the cutting surface 211, and a gap is left between the circular plate 3 and the cutting surface 211. Therefore, during the processing, the cutting surface 211 will not be damaged during the laser cutting of the circular plate 3. In this embodiment, during the processing of the circular plate 3, it is necessary to process a positioning hole on the circular plate 3, so the magnetic column 4 is arranged in the circumferential direction of the central positioning axis 2, and the pitch circle where the magnetic column 4 is located is smaller than the outer diameter of the saw blade body after processing, and larger than the pitch circle diameter of the positioning hole, thereby ensuring that there is no interference with the saw blade profile and the positioning hole position during the laser cutting process.

[0029] Embodiment 2: This embodiment discloses a processing method, which includes the following steps: S1. Select a circular plate 3 of appropriate size according to the required saw blade body size; S2, aligning the center processing hole 31 on the circular plate 3 with the center positioning axis 2; S3, energize the magnetic column 4, and the magnetic column 4 generates a magnetic attraction force on the circular plate 3; S4, laser cutting the circular plate 3.

[0030] In this embodiment, the saw blade body laser circular plate cutting profile tooling in Example 1 is used for processing and cutting. First, it is necessary to select a suitable circular plate 3 according to the size of the saw blade body actually produced. The circular plate 3 is the raw material for processing the saw blade body, wherein a center processing hole 31 is first processed on the circular plate 3 for positioning, and the center processing hole 31 is aligned with the positioning protrusion 22 on the center positioning shaft 2, and then the circular plate 3 is placed, and the circular plate 3 is preliminarily positioned and constrained by the positioning protrusion 22. After that, after the circular plate 3 is abutted and fitted on the magnetic suction column 4, before the magnetic suction column 4 is powered on, the circular plate 3 is further adjusted so that the center processing hole 31 is aligned with the center of the positioning protrusion 22, and then the magnetic suction column 4 is powered on, so that the magnetic suction column 4 generates a magnetic suction force, and the circular plate 3 is adsorbed to complete the fixation. During the processing, since the circular plate 3 is adsorbed by the magnetic suction column 4, no deviation will occur, thereby ensuring the accuracy of the processing.

[0031] In the present embodiment, the structure of the saw blade body laser circular plate cutting profile tooling used is as follows: a fixed base plate 1 is arranged at the bottom, wherein the fixed base plate 1 is circular, and the fixed base plate 1 is respectively connected with a center positioning shaft 2 arranged in the middle position and a magnetic suction column 4 arranged around the center positioning shaft 2, wherein the center positioning shaft 2 in the present embodiment includes a lower column 23, a middle column 24 and a positioning protrusion, wherein the lower column 23 is connected to the fixed base plate 1, and a screw protrusion is arranged on the side of the lower column 23 close to the fixed base plate 1, which is threadedly connected to the threaded hole on the fixed base plate 1. In this embodiment, a middle column 24 is arranged above the lower column 23, and the cross-sectional dimension of the middle column 24 is larger than the cross-sectional dimension of the lower column 23. Furthermore, in this embodiment, a notch is processed on both sides of the middle column 24 to form a wrench socket 25. During use, the wrench socket 25 can be clamped by a wrench and then rotated to connect the lower column 23 with the fixed base plate 1. Since the cross-sectional dimension of the middle column 24 is larger than the cross-sectional dimension of the lower column 23, the compressive resistance of the middle column 24 is higher, and it is more convenient to clamp the wrench socket 25 on the middle column 24 with a wrench.

[0032] Furthermore, in the present embodiment, a positioning protrusion is provided above the middle column 24, and the cross-sectional size of the positioning protrusion is smaller than that of the middle column 24 and the lower column 23. During use, the positioning protrusion needs to be connected with the center processing hole 31 on the circular plate 3 to position the circular plate 3, and it is necessary to set the size of the positioning protrusion and leave a gap between the center processing hole 31 to facilitate the picking up of the circular plate 3. At the same time, since the center processing hole 31 also needs to be processed in the subsequent laser cutting process, a certain gap is left between the center of gravity processing hole and the positioning protrusion, which can avoid damage to the positioning protrusion during the laser cutting process of the center processing hole 31.

[0033] Furthermore, in this embodiment, a detachably connected magnetic unit 43 is provided on the magnetic column 4, and the magnetic unit 43 is connected to the fixed base plate 1 through the fixed column 42, wherein the fixed column 42 and the fixed base plate 1 are fixedly connected, and since the magnetic unit 43 is detachably connected to the fixed column 42, magnetic units 43 of different specifications can be freely replaced, thereby changing the processing height of the circular plate 3. The magnetic unit 43 includes a supporting surface 41 for supporting the circular plate 3, wherein the supporting surface 41 is in contact with the circular plate 3, and an upper surface 224 located on the positioning protrusion is provided on the central positioning shaft 2, and a cutting surface 211 is provided on the side of the middle column 24 close to the positioning protrusion. In the vertical direction, the supporting surface 41 is located between the upper surface 224 and the cutting surface 211. Therefore, when the circular plate 3 is placed, the central processing hole 31 on the circular plate 3 will pass through the positioning protrusion, and then the circular plate 3 will be in contact with the supporting surface 41. Since the circular plate 3 is in contact with the supporting surface 41, the circular plate 3 will not continue to move downward to abut the cutting surface 211, and a gap is left between the circular plate 3 and the cutting surface 211. Therefore, during the processing, the cutting surface 211 will not be damaged during the laser cutting of the circular plate 3. In this embodiment, during the processing of the circular plate 3, it is necessary to process a positioning hole on the circular plate 3, so the magnetic column 4 is arranged in the circumferential direction of the central positioning axis 2, and the pitch circle where the magnetic column 4 is located is smaller than the outer diameter of the saw blade body after processing, and larger than the pitch circle diameter of the positioning hole, thereby ensuring that there is no interference with the saw blade profile and the positioning hole position during the laser cutting process.

[0034] Embodiment 3: like Figure 5 , 6 As shown in , 7, what is different from Example 1 is that in this embodiment, a positioning protrusion 22 is threadedly connected to the side of the center positioning shaft 2 away from the fixed base plate 1, and the positioning protrusion 22 includes an inclined conical surface 221 and a connecting portion 222. The connecting portion 222 is threadedly connected to the center positioning shaft 2, and an inclined conical surface 221 is provided on the side of the connecting portion 222 away from the fixed base plate 1. A center machining hole 31 is provided on the circular plate 3, and the center machining hole 31 is aligned with the inclined conical surface 221.

[0035] On the basis of Example 2, in step S2, a placement gap 6 is left between the selected positioning protrusion and the center processing hole, the center points of the center processing hole and the positioning protrusion are pre-aligned, a positioning sleeve 5 is sleeved on the center processing hole, the thickness of the positioning sleeve 5 is the same as the thickness of the placement gap 6, the positioning protrusion is rotated until the inclined cone surface abuts the positioning sleeve and stops, the positioning sleeve is removed, and step S3 is performed.

[0036] The assembly and working process of the saw blade body laser circular plate cutting profile tooling in this embodiment are as follows: in this embodiment, the positioning protrusion is provided with an inclined conical surface 221 and a connecting portion 222, wherein the inclined conical surface 221 is arranged above the connecting portion 222, the inclined conical surface 221 is a conical structure, and the connecting portion 222 is a cylindrical structure, and a threaded structure is arranged on the connecting portion 222, and a threaded hole connected to the connecting portion 222 is correspondingly arranged on the connecting spindle 21, and a rotating opening 223 is further arranged on the positioning protrusion 22, wherein the rotating opening 223 is an inner hexagon structure in this embodiment, and the rotating opening 223 can be cooperated with the rotating opening 223 by an inner hexagon wrench, so as to realize the adjustment of the connection relationship between the connecting portion 222 and the connecting spindle 21, so that the inclined conical surface 221 can move up and down driven by the adjustment of the connecting portion 222.

[0037] The connecting portion 222 can be adjusted to a suitable position by using a wrench, so that the central machining hole 31 on the circular plate 3 will not come into contact with the oblique conical surface 221 during the placement of the circular plate 3. When the circular plate 3 abuts against the supporting surface 41 on the magnetic column 4, a gap is left between the central machining hole 31 and the oblique conical surface 221. In this state, it is only necessary to place the oblique conical surface 221 in the central machining hole 31, and there is no need to align the central machining hole 31 with the oblique conical surface 221. Subsequently, the opening 223 is engaged and rotated by using the hexagonal wrench, so that the connecting portion 222 is rotated upward, driving the oblique conical surface 221 close to the central machining hole 31. Since the magnetic column 4 is not energized at this time, the magnetic column 4 does not produce any effect on the circular plate 3. The limit constraint is generated. After the inclined cone surface 221 abuts the center processing hole 31, continuing to lift the inclined cone surface 221 will gradually drive the center processing hole 31 to align with the center of the inclined cone surface 221. When the inclined cone surface 221 is completely in contact with the center processing hole 31, it can ensure that the circular plate 3 is aligned with the center of the entire device. At the same time, the circular plate 3 and the inclined cone surface 221 are in an extreme connection state. If the inclined cone surface 221 is driven to rise, the circular plate 3 will be separated from the supporting surface 41 and tilted. Therefore, after the center of the circular plate 3 is aligned, it is necessary to rotate the hexagonal wrench in the opposite direction to drive the inclined cone surface 221 to move downward, thereby re-reserving a gap between the center processing hole 31 and the inclined cone surface 221 to facilitate subsequent cutting processing.

[0038] Through the above structure and processing method, the circular plate 3 is precisely aligned, and the size of the gap between the central processing hole 31 and the inclined cone surface 221 can be flexibly controlled, thereby improving flexibility and ensuring processing quality.

[0039] Furthermore, in the process of adjusting the position of the circular plate 3, a positioning sleeve 5 is sleeved on the central processing hole 31, so that in the process of moving the oblique cone surface 221, the oblique cone surface 221 will abut against the positioning sleeve 5, and the centers of the central processing hole 31, the positioning sleeve 5, and the oblique cone surface 221 are aligned. At this time, since there is a positioning sleeve 5 between the oblique cone surface 221 and the central processing hole 31, a certain gap has been left between the central processing hole 31 and the oblique cone surface 221. Then, the magnetic suction column 4 is started to adsorb the circular plate 3 to limit the position. After the positioning sleeve 5 is removed upward, the accuracy of positioning can be guaranteed. At the same time, the gap is left during the positioning process, so the thickness of the selected positioning sleeve 5 needs to be the same as the thickness of the placement gap 6. At the same time, in this embodiment, the positioning sleeve 5 includes a sleeve body 51 sleeved with the central processing hole 31 and a limit plate 52 for providing limit. The limit plate 52 and the sleeve body 51 are staggered at right angles, so that they can be stably engaged on the central processing hole 31.

[0040] In the present embodiment, the structure of the saw blade body laser circular plate cutting profile tooling used is as follows: a fixed base plate 1 is arranged at the bottom, wherein the fixed base plate 1 is circular, and the fixed base plate 1 is respectively connected with a center positioning shaft 2 arranged in the middle position and a magnetic suction column 4 arranged around the center positioning shaft 2, wherein the center positioning shaft 2 in the present embodiment includes a lower column 23, a middle column 24 and a positioning protrusion, wherein the lower column 23 is connected to the fixed base plate 1, and a screw protrusion is arranged on the side of the lower column 23 close to the fixed base plate 1, which is threadedly connected to the threaded hole on the fixed base plate 1. In this embodiment, a middle column 24 is arranged above the lower column 23, and the cross-sectional dimension of the middle column 24 is larger than the cross-sectional dimension of the lower column 23. Furthermore, in this embodiment, a notch is processed on both sides of the middle column 24 to form a wrench socket 25. During use, the wrench socket 25 can be clamped by a wrench and then rotated to connect the lower column 23 with the fixed base plate 1. Since the cross-sectional dimension of the middle column 24 is larger than the cross-sectional dimension of the lower column 23, the compressive resistance of the middle column 24 is higher, and it is more convenient to clamp the wrench socket 25 on the middle column 24 with a wrench.

[0041] Furthermore, in the present embodiment, a positioning protrusion is provided above the middle column 24, and the cross-sectional size of the positioning protrusion is smaller than that of the middle column 24 and the lower column 23. During use, the positioning protrusion needs to be connected with the center processing hole 31 on the circular plate 3 to position the circular plate 3, and it is necessary to set the size of the positioning protrusion and leave a gap between the center processing hole 31 to facilitate the picking up of the circular plate 3. At the same time, since the center processing hole 31 also needs to be processed in the subsequent laser cutting process, a certain gap is left between the center of gravity processing hole and the positioning protrusion, which can avoid damage to the positioning protrusion during the laser cutting process of the center processing hole 31.

[0042] Furthermore, in this embodiment, a detachably connected magnetic unit 43 is provided on the magnetic column 4, and the magnetic unit 43 is connected to the fixed base plate 1 through the fixed column 42, wherein the fixed column 42 and the fixed base plate 1 are fixedly connected, and since the magnetic unit 43 is detachably connected to the fixed column 42, magnetic units 43 of different specifications can be freely replaced, thereby changing the processing height of the circular plate 3. The magnetic unit 43 includes a supporting surface 41 for supporting the circular plate 3, wherein the supporting surface 41 is in contact with the circular plate 3, and an upper surface 224 located on the positioning protrusion is provided on the central positioning shaft 2, and a cutting surface 211 is provided on the side of the middle column 24 close to the positioning protrusion. In the vertical direction, the supporting surface 41 is located between the upper surface 224 and the cutting surface 211. Therefore, when the circular plate 3 is placed, the central processing hole 31 on the circular plate 3 will pass through the positioning protrusion, and then the circular plate 3 will be in contact with the supporting surface 41. Since the circular plate 3 is in contact with the supporting surface 41, the circular plate 3 will not continue to move downward to abut the cutting surface 211, and a gap is left between the circular plate 3 and the cutting surface 211. Therefore, during the processing, the cutting surface 211 will not be damaged during the laser cutting of the circular plate 3. In this embodiment, during the processing of the circular plate 3, it is necessary to process a positioning hole on the circular plate 3, so the magnetic column 4 is arranged in the circumferential direction of the central positioning axis 2, and the pitch circle where the magnetic column 4 is located is smaller than the outer diameter of the saw blade body after processing, and larger than the pitch circle diameter of the positioning hole, thereby ensuring that there is no interference with the saw blade profile and the positioning hole position during the laser cutting process.
