[0041] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0042] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0043] A tool angle measuring instrument for CNC tool manufacturing, such as Figures 1-6 As shown, it includes a mounting base plate 1, and an L-shaped base plate 11 is connected to the upper side of the mounting base plate 1. The base plate 11 has an inner side surface 111 and an inner side surface 112 that are perpendicular to each other. The inner side surface 111 of the base plate 11 is parallel to the longitudinal direction of the CNC tool 01 (as shown in FIG. Figure 4), the inner side surface 112 of the substrate 11 is parallel to the horizontal cutting direction of the CNC tool 01; a tool clamping group 2 for clamping the CNC tool 01 is provided on the mounting base 1, and the tool clamping group 2 is suitable for making the blade of the CNC tool 01 perpendicular to the inner side surface 111 of the L-shaped substrate 11. When the blade of the tool is perpendicular to the inner side surface 111 of the L-shaped substrate 11, the intersection of the inner side surface 111 and the inner side surface 112 of the substrate 11 is suitable for contacting the tip of the CNC tool 01, and the main cutting edge of the CNC tool 01 corresponds to the inner side surface 112 of the substrate 11, and the secondary cutting edge of the CNC tool 01 corresponds to the inner side surface 111 of the substrate 11, so in the subsequent When measuring the angle of the CNC tool 01, if it is assumed that the CNC tool 01 performs a horizontal cutting perpendicular to the axial direction of the tool when working, then the inner side surface 112 of the substrate 11 can be assumed to be the processing base surface of the tool. At this time, the angle between the secondary cutting surface 03 of the CNC tool 01 and the inner side surface 112 of the substrate 11 is measured. Similarly, if it is assumed that the CNC tool 01 performs a longitudinal cutting parallel to the axial direction of the tool when working, then the inner side surface 111 of the substrate 11 can be assumed to be the processing base surface of the tool. At this time, the angle between the main cutting surface 02 of the CNC tool 01 and the inner side surface 111 of the substrate 11 is measured; three pillars 41 are connected to the upper side of the mounting base 1, and the pillars 41 are connected to the positioning holes. The panel 43 above the substrate 11 is embedded with a transparent circular angle scale 61. The reference point of the circular angle scale 61 is located directly above the intersection of the inner side surface 111 and the inner side surface 112 of the substrate 11. The leftmost scale line of the circular angle scale 61 is the 0-degree line. The leftmost scale line to the rightmost scale line of the circular angle scale 61 are all flush with the inner side surface 111 of the substrate 11. The uppermost scale line of the circular angle scale 61 is the 90-degree line. The uppermost scale line to the lowermost scale line of the circular angle scale 61 are all flush with the inner side surface 112 of the substrate 11. When the blade of the CNC tool 01 is perpendicular to L When the inner side surface 111 of the shaped substrate 11 and the tip of the CNC tool 01 are in contact with the intersection of the inner side surface 111 and the inner side surface 2 112 of the substrate 11, the extension line of the main cutting surface 02 and the extension line of the secondary cutting surface 03 of the CNC tool 01 can extend from the reference point of the circular angle dial 61 to the scale line of the circular angle dial 61. A measuring lens 63 is installed on the pillar 41 and is located above the panel 43. The measuring lens 63 is concentric with the circular angle dial 61. The measuring lens 63 is suitable for cooperating with the scale lines on the circular angle dial 61 and measuring and recording the angle of the CNC tool 01 below the panel 43 through the transparent circular angle dial 61.

[0044] like Figure 2 、 Figure 3 and Figure 7As shown, it also includes a resistance block 31. There are two relative resistance blocks 31 sliding on the substrate 11. The resistance blocks 31 slide in an arc-shaped trajectory. The center of the arc-shaped sliding trajectory of the resistance block 31 is the intersection of the inner side surface 111 and the inner side surface 112 of the substrate 11. The two resistance blocks 31 are respectively located on the inner side surface 111 and the inner side surface 112 of the substrate 11. The resistance block 31 has a resistance surface suitable for fitting the CNC tool 01. The resistance surface of the resistance block 31 is located on the substrate 11. On the inner side of the L-shaped substrate 11, an adjustment component is provided on the substrate 11 for making the resistance block 31 slide and resist on the CNC tool 01. When the blade of the CNC tool 01 is perpendicular to the inner side surface 111 of the L-shaped substrate 11 and the tip of the CNC tool 01 resists at the intersection of the inner side surface 111 and the inner side surface 112 of the substrate 11, the resistance block 31 is made to slide and resist on the CNC tool 01 through the adjustment component. Specifically, the resistance block 31 on the inner side surface 111 slides and drives the resistance surface to fit the CNC tool 01. The main cutting surface 02 of the CNC tool 01 is controlled so that the resistance block 31 on the inner side surface 112 slides and drives the resistance surface to fit the secondary cutting surface 03 of the CNC tool 01; the upper side of the resistance block 31 is connected to a stopper 32 through a transmission rod, and the stopper 32 has an alignment surface flush with the resistance surface of the resistance block 31. The stopper 32 is connected to a pointer 62 flush with the alignment surface of the stopper 32, and the pointer 62 points to the scale line of the circular angle scale 61, so when the resistance block 31 slides and resists the CNC tool 01, the resistance block 31 will drive the stopper 32 to rotate through the transmission rod, and the stopper 32 will drive the pointer 62 to rotate with the intersection of the inner side surface 111 and the inner side surface 2 112 of the substrate 11 as the center of the circle, and the two pointers 62 are used to replace the extension lines of the inner side surface 111 and the inner side surface 2 112 of the substrate 11 for visualization, and the pointer 62 is used to point to the scale line of the circular angle dial 61, so that the measuring lens 63 can clearly and directly measure the angle of the CNC tool 01.

[0045] like Figure 6 and Figure 7 As shown, a laser line emitter 621 is also included. The laser line emitter 621 is installed on the pointer 62. The laser head of the laser line emitter 621 is perpendicular to the end face of the circular angle scale 61. The laser line (not the laser point) emitted by the laser line emitter 621 is projected flush with the contact surface of the contact block 31. When the contact block 31 contacts the CNC tool 01, the movement of the pointer 62 will drive the movement of the laser line emitter 621. The laser line emitter 621 is used to emit a laser line to the measuring lens 63 through the circular angle scale 61, thereby measuring the position of the laser line projected on the scale line of the circular angle scale 61, and then measuring the angle of the CNC tool 01.

[0046] like Figure 5-10As shown, it also includes a back plate 42, the support 41 is connected to the back plate 42 located between the substrate 11 and the panel 43, the middle of the back plate 42 is provided with a through hole for the stopper 32 to pass through, the upper end of the stopper 32 extends through the through hole of the back plate 42 to between the back plate 42 and the panel 43, and an arc-shaped photoelectric sensor module 44 concentric with the circular angle dial 61 is installed between the back plate 42 and the panel 43. In this embodiment, the arc-shaped photoelectric sensor module 44 is composed of a plurality of photoelectric sensors arranged along an arc, and the first end and the second end of the arc-shaped photoelectric sensor module 44 are respectively aligned with the circular angle dial 61. The arc photoelectric sensor module 44 is aligned with the inner side surface 111 and the inner side surface 2 112 of the substrate 11, and is located on the side of the block 32 away from the pointer 62. The inner diameter of the arc photoelectric sensor module 44 is larger than the outer diameter of the circular angle scale 61 to prevent the arc photoelectric sensor module 44 from blocking the circular angle scale 61. A slide 51 is slid on the panel 43. The slide 51 slides with the inner side surface 111 and the inner side surface 2 112 of the substrate 11 at a perpendicular intersection as the center of the circle. The slide 51 is equipped with a first end of the arc photoelectric sensor module 44. The corresponding laser emitter 52 is used to emit a laser point. The stopper 32 connected to the abutment block 31 on the inner side surface 111 of the substrate 11 is located between the laser emitter 52 and the first end of the arc-shaped photoelectric sensor module 44. When the abutment block 31 on the inner side surface 111 of the substrate 11 abuts against the main cutting surface 02 of the CNC tool 01, the stopper 32 blocks the laser emitter 52 and the first end of the arc-shaped photoelectric sensor module 44. The laser emitted by the laser emitter 52 does not irradiate the arc-shaped photoelectric sensor module 44. Slide 1 51 drives laser emitter 1 52 to rotate clockwise. When the laser emitted by laser emitter 1 52 is no longer blocked by block 32, arc photoelectric sensor module 44 receives and records the first light signal from laser emitter 1 52. Thus, an angle is obtained from the first end of arc photoelectric sensor module 44 to the position where arc photoelectric sensor module 44 first receives the light signal from laser emitter 1 52. The angle plus 90 degrees is the angle between the secondary cutting surface 03 of CNC tool 01 and inner side surface 2 112 of substrate 11, and the usage is diversified.

[0047] like Figure 8 and Figure 10As shown, it also includes a slide 2 53, and a slide 2 53 slides on the panel 43. The slide 2 53 slides with the intersection of the inner side 111 and the inner side 2 112 of the substrate 11 perpendicular to each other as the center of the circle. A laser emitter 2 54 corresponding to the second end of the arc-shaped photoelectric sensor module 44 is installed on the slide 2 53. The laser emitter 2 54 is used to emit a laser point. The stopper 32 connected to the contact block 31 on the inner side 2 112 of the substrate 11 is located between the laser emitter 2 54 and the arc-shaped photoelectric sensor module. 44, the laser emitter 2 54 is used in the same way as the laser emitter 1 52, so that the slide 2 53 drives the laser emitter 2 54 to rotate counterclockwise. I will not go into details here. Finally, an angle is obtained between the second end of the arc-shaped photoelectric sensor module 44 and the position where the arc-shaped photoelectric sensor module 44 first receives the optical signal of the laser emitter 2 54. The angle plus 90 degrees is the angle between the main cutting surface 02 of the CNC tool 01 and the inner side surface 111 of the substrate 11.

[0048] like Figures 8-10 As shown, it also includes a gear 55 that is rotatable on the panel 43, and the gear 55 can be driven or electric, and is specifically set according to actual needs; the slide 2 53 is connected to an arc rack 1 56 with teeth located on the inside, and the slide 1 51 is connected to an arc rack 2 57 with teeth located on the outside through a connecting rod, and the arc rack 1 56 and the arc rack 2 57 are relatively meshed on the front and rear sides of the gear 55, so that the slide 2 53 drives the laser emitter 2 54 to rotate counterclockwise, and the slide 1 51 drives the laser emitter 1 52 to rotate clockwise through the meshing of the gear 55, the arc rack 1 56 and the arc rack 2 57, and the operation is convenient.

[0049] like Figure 11 As shown, the tool clamping group 2 includes a support plate 1 21 and a support plate 2 24, the mounting base 1 is connected to the support plate 1 21 and the support plate 2 24 located on the right side of the support plate 1 21, a clamping plate 22 perpendicular to the inner side 111 of the base plate 11 slides on the support plate 1 21, and two front and rear relative compression springs 23 are connected between the clamping plate 1 22 and the support plate 1 21, a cylinder 25 is installed on the mounting base 1, and the telescopic end of the cylinder 25 is connected to the clamping plate 2 26 sliding on the support plate 2 24, and the front and rear ends of the clamping plate 1 22 are inclined away from the clamping plate 2 26, and the clamping plate 2 26 is parallel to The inner side surface 112 of the substrate 11 is used to place the CNC tool 01 whose angle needs to be measured between the clamp 1 22 and the clamp 2 26, and the clamp 1 22 and the clamp 2 26 are used to limit the blade of the CNC tool 01 so that the blade of the CNC tool 01 is perpendicular to the inner side surface 111 of the L-shaped substrate 11. At the same time, the tip of the CNC tool 01 is assisted to contact the intersection of the inner side surface 111 and the inner side surface 112 of the substrate 11, and then the cylinder 25 is controlled to drive the clamp 26 to move left to clamp the CNC tool 01 to the clamp 1 22, thereby completing the alignment and fixation of the CNC tool 01.

[0050] like Figure 3 、 Figure 11 、 Figure 12 and Figure 13 As shown, the adjustment component includes a bracket 33, and the bracket 33 is connected to the upper side of the mounting base 1. The bracket 33 has an arc rod, and the arc rod of the bracket 33 takes the intersection of the inner side surface 111 and the inner side surface 2 112 of the substrate 11 as the center of the circle. The two interference blocks 31 slide on the two ends of the arc rod of the bracket 33 respectively, and an arc spring 34 surrounding the arc rod on the bracket 33 is connected between the interference block 31 and the bracket 33. In this way, when the tip of the CNC tool 01 contacts the intersection of the inner side surface 111 and the inner side surface 2 112 of the substrate 11, the interference block 31 can adaptively interfere with the CNC tool 01 under the action of the arc spring 34, so that the CNC tool 01 only needs to be aligned and placed, so that the interference block 31 can drive the stop block 32 and the pointer 62 to move automatically, which is convenient for the measurement operation and can also adapt to tools of different sizes.

[0051] like Figure 14 As shown, a contact plate 12 is also included. An L-shaped contact plate 12 is installed on the substrate 11. The two inner side surfaces of the contact plate 12 are perpendicular to each other and are flush with the inner side surface 111 and the inner side surface 2 112 of the substrate 11 respectively. The contact plate 12 is suitable for replacing the substrate 11 to contact the tip of the CNC tool 01. By disassembling and replacing the new contact plate 12, the influence of scratches on the tip of the tool on the angle measurement can be avoided.
