[0044] The term "a plurality of" appearing in this utility model refers to two or more (including two).

[0045] The following will be combined with Figures 1 to 8 to describe the turning tool angle measuring instrument 100 of this utility model.

[0046] As Figures 1 to 8As shown, the tool angle measuring instrument 100 according to an embodiment of the present utility model includes a mounting bracket 10, a fixing seat 20, an inclinometer assembly 30, and a calibration plate 40. The fixing seat 20 is movable relative to the mounting bracket 10 within a base plane S, and the fixing seat 20 is used to fix a tool A. The inclinometer assembly 30 is mounted on the mounting bracket 10, and the position of the inclinometer assembly 30 within a set vertical plane is adjustable. The inclinometer assembly 30 includes an inclinometer body 301 and a measuring plate 302. The measuring plate 302 and the inclinometer body 301 can rotate synchronously about a rotation axis L, and the rotation axis L is perpendicular to the set vertical plane. The measuring plate 302 includes a vertical edge 3021 extending along a first direction F1 and / or a horizontal edge 3022 extending along a second direction F2. The calibration plate 40 defines a calibration surface 401. The base plane S, the set vertical plane, and the calibration surface 401 are perpendicular to each other pairwise to form a three-dimensional space rectangular coordinate system of the tool angle measuring instrument 100. The first direction F1 is parallel to the calibration surface 401, the first direction F1 is perpendicular to the rotation axis L, and the second direction F2 is perpendicular to the calibration surface 401.

[0047] Specifically, during use, the position of the mounting bracket 10 within the base plane S is fixed. The fixing seat 20 is used to fix the tool A so that the position of the tool A can remain unchanged during the angle measurement process. The base plane S is usually a horizontal plane. To ensure good measurement accuracy and precision, before measuring the angle of the tool A, the horizontal edge 3022 of the measuring plate 302 can be closely attached to the upper surface of the fixing seat 20, and then the inclinometer body 301 is reset to zero, so that the upper surface for fixing the tool A forms the base plane S. At the same time, this base plane S is also the base plane of the tool A. It should be noted that the base plane S is a plurality of mutually parallel planes, rather than just a specific plane.

[0048] When measuring the rake angle and clearance angle of the tool A, first ensure that the inclinometer assembly 30 is fixed. The main cutting edge of the tool A is attached to the calibration surface 401 of the calibration plate 40 (as Figure 6 shown), so that the main cutting edge of the tool A is disposed within the three-dimensional space rectangular coordinate system defined by the tool angle measuring instrument 100. Then, keep the positions of the tool A and the fixing seat 20 fixed, and move the positions of the inclinometer body 301 and the measuring plate 302 within the set vertical plane and the rotation angle relative to the rotation axis L, so that the horizontal edge 3022 of the measuring plate 302 is attached to the rake face of the tool A (as Figure 7 shown). At this time, the reading shown by the inclinometer body 301 is the rake angle of the tool A. Keep the positions of the tool A and the fixing seat 20 fixed, and move the positions of the inclinometer body 301 and the measuring plate 302 within the set vertical plane and the rotation angle relative to the rotation axis L, so that the vertical edge 3021 of the measuring plate 302 is attached to the flank face of the tool A. At this time, the reading shown by the inclinometer body 301 is the clearance angle of the tool A.

[0049] When measuring the edge inclination angle of turning tool A, place turning tool A horizontally on the fixed seat 20 so that the base surface S of turning tool A fits against the upper surface of the fixed seat 20. Move the positions of turning tool A, the inclinometer body 301, and the measuring plate 302 in the set vertical plane so that the transverse edge 3022 of the measuring plate 302 fits against the main cutting edge. At this time, the reading shown by the inclinometer body 301 is the edge inclination angle of turning tool A.

[0050] When measuring the secondary clearance angle of turning tool A, first ensure that the inclinometer assembly 30 is fixed. Fit the secondary cutting edge of turning tool A against the calibration surface 401 of the calibration plate 40, thereby placing the secondary cutting edge of turning tool A in the three-dimensional space rectangular coordinate system defined by the turning tool angle measuring instrument 100. Then, keep the positions of turning tool A and the fixed seat 20 fixed. Move the positions of the inclinometer body 301 and the measuring plate 302 in the set vertical plane and the rotation angle relative to the rotation axis L so that the vertical edge 3021 of the measuring plate 302 fits against the secondary flank. At this time, the reading shown by the inclinometer body 301 is the secondary clearance angle of turning tool A.

[0051] When measuring the main cutting edge angle and the secondary cutting edge angle of turning tool A, make the feed direction of turning tool A parallel to the base surface, or place turning tool A vertically. Then, move the positions of the inclinometer body 301 and the measuring plate 302 in the set vertical plane and the rotation angle relative to the rotation axis L, and move the position of turning tool A so that the vertical edge 3021 of the measuring plate 302 fits against the main cutting edge of turning tool A. At this time, the reading shown by the inclinometer body 301 is the main cutting edge angle of turning tool A. Move the positions of the inclinometer body 301 and the measuring plate 302 in the set vertical plane and the rotation angle relative to the rotation axis L so that the transverse edge 3022 of the measuring plate 302 fits against the secondary cutting edge of turning tool A. At this time, the reading shown by the inclinometer body 301 is the secondary cutting edge angle of turning tool A.

[0052] The turning tool angle measuring instrument 100 according to the embodiment of the present invention defines a base surface S, a set vertical plane, and a calibration surface 401, and the base surface S, the set vertical plane, and the calibration surface 401 are perpendicular to each other in pairs, forming a three-dimensional space rectangular coordinate system. Place turning tool A in a suitable position in the three-dimensional space rectangular coordinate system so that the measuring plate 302 fits against the corresponding position of turning tool A, so that the geometric angle corresponding to turning tool A can be obtained through the reading of the inclinometer body 301. Thus, compared with reading through pointer scales, the turning tool angle measuring instrument 100 of the present invention has high measurement accuracy, good repeat measurement accuracy, and is flexible and convenient to use.

[0053] According to some embodiments of the present invention, reference may be made to Figure 3 and Figure 4, the measuring plate 302 includes a plurality of plate segments 3023 connected in sequence along the first direction F1. In the first direction F1, the size of the plate segment 3023 closer to the rotation axis L in the second direction F2 is larger than the size of the plate segment 3023 farther from the rotation axis L in the second direction F2. At least part of the edges of the plate segment 3023 are formed as transverse edges 3022 and vertical edges 3021. In this way, the measuring plate 302 is more convenient and flexible to use and can be used for measuring various types of turning tools A.

[0054] Exemplarily, for example, the measuring plate 302 may be symmetric about the vertical plane passing through the rotation axis L. The measuring plate 302 includes three plate segments 3023 connected in sequence along the first direction F1. And when the reading of the inclinometer body 301 is zero, the first direction F1 is the up-down direction. Along the direction from top to bottom, the sizes of the three plate segments 3023 in the second direction F2 gradually decrease, and the projection of each plate segment 3023 in the direction parallel to the rotation axis is a rectangle.

[0055] In some embodiments, the sizes of at least two transverse edges 3022 in the direction parallel to the rotation axis L are different, and the sizes of at least two vertical edges 3021 in the direction parallel to the rotation axis L are different. That is to say, the contact area of some transverse edges 3022 in contact with the turning tool A is larger, and the contact area of some transverse edges 3022 in contact with the turning tool A is smaller. The contact area of some vertical edges 3021 in contact with the turning tool A is larger, and the contact area of some vertical edges 3021 in contact with the turning tool A is smaller. The user can select appropriate vertical edges 3021 and transverse edges 3022 according to the actual measurement requirements to better fit the surface of the turning tool A to obtain more accurate measurement results.

[0056] Exemplarily, the measuring plate 302 with transverse edges 3022 and vertical edges 3021 having larger sizes in the direction parallel to the rotation axis L is suitable for measuring the main cutting edge angle and the secondary cutting edge angle of the turning tool A with a larger rake angle and a larger edge inclination angle. The transverse edges 3022 and vertical edges 3021 with larger sizes in the direction parallel to the rotation axis L can cover the entire main cutting edge or secondary cutting edge of the turning tool A to achieve the purpose of accurate measurement.

[0057] According to some embodiments of the present invention, reference may be made to Figure 3 and Figure 4, notches 3024 are formed at the horizontal edge 3022 and the vertical edge 3021, and the notches 3024 penetrate in the extending direction of the rotation axis L. For some turning tools A (such as the model used in the experimental class), due to long-term use, bumps, etc., the surface may be uneven. Notches 3024 are formed at the horizontal edge 3022 and the vertical edge 3021 of the measuring plate 302. In this way, when the horizontal edge 3022 and the vertical edge 3021 are in contact with the turning tool A, the notches 3024 can avoid some uneven surfaces and can be more stably in contact with the surface of the turning tool A, so as to obtain more accurate measurement results. Exemplarily, the notch 3024 can be a triangular notch or a notch 3024 of other shapes. One horizontal edge 3022 or one vertical edge 3021 can be provided with one notch 3024 or multiple notches 3024.

[0058] According to some embodiments of the present invention, reference can be made to Figure 3 and Figure 4 , a relief groove 3025 is formed between the adjacent horizontal edge 3022 and the vertical edge 3021, and the relief groove 3025 penetrates in the extending direction of the rotation axis L.

[0059] In the embodiments without the relief groove 3025, when the horizontal edge 3022 or the vertical edge 3021 is in contact with the surface of the turning tool A, the tip of the turning tool A may interfere with the connection between the horizontal edge 3022 and the vertical edge 3021, affecting the smoothness of the measurement. The setting of the relief groove 3025 can avoid the cutting edge part of the turning tool A, which is beneficial to the smooth progress of the measurement process. Exemplarily, the relief groove 3025 can be an arc-shaped relief groove or a polygonal relief groove.

[0060] According to some embodiments of the present invention, as Figures 3 to 5 shown, the inclinometer assembly 30 includes a clamping bracket 303 for installing the inclinometer body 301. The clamping bracket 303 is installed on the mounting bracket 10 and is rotatable around the rotation axis L, and the measuring plate 302 is detachably arranged on the clamping bracket 303. For example, the inclinometer body 301 can be detachably connected to the clamping bracket 303 to facilitate the replacement of the inclinometer body 301 or to facilitate disassembly for charging the inclinometer body 301.

[0061] The measuring plate 302 is detachably arranged on the clamping bracket 303. In this way, when the measuring plate 302 is deformed or damaged, the measuring plate 302 can be conveniently replaced, and at the same time, other parts of the turning tool angle measuring instrument 100 can still be used normally, which is beneficial to reducing the replacement cost. For example, the measuring plate 302 can be connected to the clamping bracket 303 by bolts, and the connection stability is good.

[0062] According to some embodiments of the present invention, asFigure 3 and Figure 4 As shown in Figure 4 , the calibration plate 40 is installed on the inclinometer assembly 30. The calibration plate 40 is rotatable relative to the inclinometer assembly 30. The turning tool angle measuring instrument 100 further includes a positioning member 50. In a state where the calibration plate 40 is in contact with the positioning member 50, the calibration surface 401, the base surface S, and the set vertical plane are perpendicular to each other in pairs.

[0063] It should be noted that the calibration plate 40 is rotatable relative to the inclinometer assembly 30. In this way, when it is not necessary for the calibration plate 40 to be in contact with the turning tool A, the position of the calibration plate 40 can be rotated so that the calibration plate 40 can be located at a position farther from the lateral edge 3022 or the vertical edge 3021, thereby reducing the possibility of interference between the calibration plate 40 and the turning tool A during the measurement process. Exemplarily, the calibration plate 40 can rotate around the installation axis R, and the installation axis R is parallel to the rotation axis L. After rotating the calibration plate 40, the position of the calibration plate 40 can be fixed at the rotated position. Exemplarily, the calibration plate 40 includes a first plate and a second plate that are connected and arranged in an L shape. The first plate is used to be rotatably connected to the measuring plate 302, and the second plate defines the calibration surface 401.

[0064] Exemplarily, the positioning member 50 can be a positioning post, and the positioning post can be provided on the measuring plate 302. When the calibration plate 40 abuts against the positioning post, the calibration surface 401, the base surface S, and the set vertical plane are perpendicular to each other in pairs.

[0065] Exemplarily, the calibration plate 40 can be provided with a positioning groove that can cooperate with the positioning post. When the positioning post abuts against the inner wall of the positioning groove, the calibration surface 401, the base surface S, and the set vertical plane are perpendicular to each other in pairs. For example, the positioning groove can be a cylindrical positioning groove that fits the outer peripheral surface of the positioning post.

[0066] In some embodiments, on the premise that the calibration surface 401, the base surface S, and the set vertical plane are perpendicular to each other in pairs, the calibration surface 401 is located outside the vertical edge 3021 in the second direction F2, so that the turning tool A can be in good contact with the calibration surface 401 without interfering with the vertical edge 3021.

[0067] According to some embodiments of the present utility model, the inclinometer assembly 30 further includes a clamping bracket 303. The clamping bracket 303 is installed on the mounting bracket 10 and is rotatable about the rotation axis L. The inclinometer body 301 is provided with a first ferromagnetic member, and the clamping bracket 303 is provided with a second ferromagnetic member. The first ferromagnetic member and the second ferromagnetic member can be mutually attracted. That is to say, the clamping bracket 303 and the inclinometer body 301 can be mutually connected and fixed by the mutual attraction of the first ferromagnetic member and the second ferromagnetic member. At the same time, it is also convenient for the inclinometer body 301 and the clamping bracket 303 to be disassembled from each other. Specifically, both the first ferromagnetic member and the second ferromagnetic member can be magnetic members, or one of the first ferromagnetic member and the second ferromagnetic member is a magnetic member, and the other of the first ferromagnetic member and the second ferromagnetic member is a ferrous metal member.

[0068] Exemplarily, the first ferromagnetic members can be provided on the periphery and the back of the inclinometer body 301. Correspondingly, the second ferromagnetic members are also provided at the positions corresponding to the periphery and the back of the inclinometer body 301 on the clamping bracket 303, so as to facilitate the good suction and fixation between the inclinometer body 301 and the clamping bracket 303. Exemplarily, the second ferromagnetic member can be made of a steel magnetic material.

[0069] According to some embodiments of the present utility model, the inclinometer assembly 30 further includes a clamping bracket 303. The clamping bracket 303 is installed on the mounting bracket 10 and is rotatable about the rotation axis L. The clamping bracket 303 includes two clamping members 3031 oppositely arranged along a set direction and a connecting member 3032 connected between the two clamping members 3031. The inclinometer body 301 is arranged between the two clamping members 3031, and the inclinometer body 301 is in interference fit or transition fit with the two clamping members 3031; by making the inclinometer body 301 and the two clamping members 3031 in interference fit or transition fit, the connection and fixation between the inclinometer body 301 and the clamping bracket 303 are realized, and the structure of the clamping bracket 303 is simple.

[0070] According to some embodiments of the present utility model, as Figures 3 to 5 shown, the inclinometer assembly 30 further includes a clamping bracket 303. The clamping bracket 303 is installed on the mounting bracket 10 and is rotatable about the rotation axis L. The clamping bracket 303 includes two clamping members 3031 oppositely arranged along a set direction and a connecting member 3032 connected between the two clamping members 3031. One of the inclinometer body 301 and the clamping member 3031 is provided with a protrusion 3033, and the other of the inclinometer body 301 and the clamping member 3031 is provided with a slot 3034. The protrusion 3033 and the slot 3034 are in plug-in fit, so as to realize the connection and fixation between the inclinometer body 301 and the clamping bracket 303, the clamping stability is good, and the consistency of the installation position of the inclinometer body 301 is good.

[0071] In some embodiments, an avoidance opening may be provided at the position of the clamping member 3031 corresponding to the charging jack of the inclinometer body 301, so as to facilitate charging the inclinometer body 301 without disassembling the inclinometer body 301 and the clamping bracket 303.

[0072] In some embodiments, the clamping member 3031 is provided with a second ferromagnetic member, and the inclinometer body 301 is provided with a first ferromagnetic member. The clamping member 3031 and the inclinometer body 301 can be connected and fixed to each other by the mutual attraction of the first ferromagnetic member and the second ferromagnetic member.

[0073] Exemplarily, the clamping bracket 303 may be provided with a hollow portion to reduce the weight of the clamping bracket 303.

[0074] According to some embodiments of the present invention, as Figure 1 and Figure 2 shown, the mounting bracket 10 includes a vertical guide rail 101, a horizontal guide rail 102, a slider 103 and a locking assembly 104. The horizontal guide rail 102 is mounted on the vertical guide rail 101 and can move up and down relative to the vertical guide rail 101. The slider 103 is provided on the horizontal guide rail 102 and can move in the horizontal direction along the horizontal guide rail 102. The inclinometer assembly 30 is mounted on the slider 103, so that the inclinometer assembly 30 can move in a set vertical plane following the slider 103. The locking assembly 104 is used to lock the position of the slider 103 on the horizontal guide rail 102 to facilitate fixing the position of the inclinometer assembly 30 as needed.

[0075] The mounting bracket 10 includes a vertical guide rail 101, a horizontal guide rail 102 and a slider 103. The inclinometer assembly 30 is mounted on the slider 102 to realize the movement of the inclinometer assembly 30 in a set vertical plane. The structure of the mounting bracket 10 is simple, the use cost is low, the service durability is good, and it is convenient to use.

[0076] Exemplarily, the vertical guide rail 101 is a gear-rack guide rail, which has a simple structure and is convenient to use.

[0077] According to some embodiments of the present invention, as Figure 1 and Figure 2As shown, the turning tool angle measuring instrument 100 further includes a bottom plate 60. The mounting bracket 10 and the fixing base 20 are arranged on the bottom plate 60. The fixing base 20 includes a magnetic base. The magnetic base includes an open state and a closed state. In the open state, the magnetic base can be magnetically attracted to the bottom plate 60 and / or the turning tool A. In the state where the magnetic base is magnetically attracted to the bottom plate 60, the position of the magnetic base relative to the bottom plate 60 can be fixed, so that the magnetic base is not likely to move relative to the bottom plate 60. In the state where the magnetic base is magnetically attracted to the turning tool A, the position of the turning tool A relative to the magnetic base can be fixed, so that the turning tool A is not likely to move relative to the magnetic base, facilitating the accurate and convenient measurement of the geometric angle of the turning tool A. In the closed state, the magnetic base can be separated from the bottom plate 60 and / or the turning tool A. That is to say, when the magnetic base is in the closed state, the magnetic base and the turning tool A can be conveniently moved to the required positions.

[0078] By adopting a magnetic base and using the magnetic attraction method to fix the fixing base 20 and the turning tool A, the fixing process is more convenient and fast.

[0079] Exemplarily, the bottom plate 60 can be a high-permeability optical flat plate, and a plurality of mounting holes can be preset on the bottom plate 60, so as to flexibly adjust the fixing position of the mounting bracket 10 according to requirements.

[0080] Exemplarily, the magnetic base can have a through groove. The inner wall surface of the through groove includes two inclined surfaces, and the included angle between the two inclined surfaces is 90°. The through groove is open at both ends in the extending direction. In this way, when the turning tool A needs to be placed vertically, the turning tool A can be partially placed in the through groove and can be attached to the two inclined surfaces to better fix the turning tool A. For example, when measuring the main cutting edge angle and the auxiliary cutting edge angle of the turning tool A, the turning tool A can be better fixed.

[0081] In some embodiments, a rubber shock pad is provided at the bottom of the bottom plate 60 to improve the stable placement effect of the bottom plate 60.

[0082] According to some embodiments of the present invention, such as Figure 1 and Figure 8As shown, the turning tool angle measuring instrument 100 further includes a lighting lamp 70, and the position of the light emitting surface of the lighting lamp 70 in the direction parallel to the set vertical plane is adjustable. When the measuring plate 302 is attached to the turning tool A, the light emitting surface of the lighting lamp 70 can be oriented towards the gap between the measuring plate 302 and the turning tool A. When it is observed that the gap between the measuring plate 302 and the turning tool A is almost opaque, it can be determined that the measuring plate 302 and the turning tool A are in good contact. By providing the lighting lamp 70, it can be better determined whether the measuring plate 302 and the turning tool A are in good contact, so as to improve the measurement accuracy of the geometric angle of the turning tool A. The position of the light emitting surface of the lighting lamp 70 can be adjusted at least in the direction parallel to the set vertical plane, so that the light emitting surface of the lighting lamp 70 can be adjusted to a suitable position to better observe the degree of contact between the turning tool A and the measuring plate 302.

[0083] Exemplarily, the lighting lamp 70 can be a lighting lamp with a magnetic base, that is, the magnetic base of the lighting lamp 70 can be magnetically attracted to the bottom plate 60 to fix the position of the lighting lamp 70. At the same time, it can also be moved relative to the bottom plate 60 to adjust the position of the lighting lamp 70 to a suitable use position.
