[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-2, a device for measuring the angle of an inclined surface and a cone surface, comprising a base 100 and a plurality of supports fixedly mounted on the bottom of the base 100, wherein the bottom of the base 100 is fixedly connected with four sets of legs for supporting the entire base 100 to keep the device horizontal, and further comprising a measuring unit 1 arranged on the base 100 for measuring the transverse and longitudinal directions of inclined surface and cone surface parts, wherein the measuring unit 1 comprises a longitudinal measuring mechanism 11 arranged on one side of the base 100 for adjusting the longitudinal distance from the inclined surface and cone surface parts, a transverse measuring mechanism 12 for adjusting the transverse distance from the inclined surface and cone surface parts is arranged on one side of the base 100 close to the longitudinal measuring mechanism 11, and a clamping unit 2 for clamping inclined surface and cone surface parts of different sizes and shapes is arranged on the transverse measuring mechanism 12, wherein the clamping unit 2 comprises a lifting mechanism 21 arranged on the transverse measuring mechanism 12 for adjusting the height of the inclined surface and cone surface parts to cooperate with the longitudinal measuring mechanism 11 to measure the inclined surface and cone surface parts, and the lifting mechanism 21 is connected with a clamping mechanism 22 for clamping and fixing the inclined surface and cone surface parts;

[0033] The longitudinal displacement refers to the displacement along the y direction of the inclined and conical parts, and the lateral displacement refers to the displacement along the x direction of the inclined and conical parts. Because the longitudinal distance of the inclined and conical parts changes with the displacement of the lateral distance, after measuring the lateral distance of the inclined and conical parts and the longitudinal distance corresponding to the lateral distance, according to the inverse trigonometric function formula: tan(a)=y / x, the calculation formula of angle a can be known: a=arctan(y / x), and angle a is the angle of the inclined or conical surface of the workpiece.

[0034] Reference Figure 3-Figure 4 The longitudinal measuring mechanism 11 includes a slide rail 111 arranged on one side of the base 100 in the length direction, a square groove 112 is opened on the base 100, and the size of the slide rail 111 matches that of the square groove 112, a support arm 113 is slidably installed in the slide rail 111 through a slider 117, the support arm 113 and the slider 117 are detachably connected, and the slider 117 and the slide rail 111 are detachably connected through a fastener, and the fastener can be a bolt, a handle 116 is fixedly connected to either side in the width direction of the support arm 113, a cantilever 114 is detachably fixedly connected to the top of the support arm 113, and a first linear displacement sensor 115 is connected to the end of the cantilever 114 away from the support arm 113;

[0035] The lateral measuring mechanism 12 includes a boss 121 fixedly mounted on the base 100, and a raceway 122 is symmetrically provided in the length direction of the boss 121, a fixed block 123 is fixedly mounted on one side of the boss 121, and the fixed block 123 is internally threadedly connected with a first threaded rod 124, one end of the first threaded rod 124 passing through the fixed block 123 is fixedly connected with a handle 125, and a pattern is provided in the circumferential direction of the handle 125 for increasing friction during driving, one end of the first threaded rod 124 is fixedly connected with a disc sleeve 126, and one end of the first threaded rod 124 close to the disc sleeve 126 is connected with a moving frame 127 through a bearing, and both ends of the moving frame 127 in the length direction match the raceway 122, a second linear displacement sensor 128 is fixedly mounted on one side of the boss 121, and the second linear displacement sensor 128 abuts against the disc sleeve 126 for detecting the lateral movement distance of the moving frame 127;

[0036] When measuring the longitudinal distance of the inclined surface and conical surface parts, the position of the support arm 113 on the base 100 should be adjusted by the slider 117 according to the transverse length of the inclined surface and conical surface parts, so that the first linear displacement sensor 115 at the top of the support arm 113 contacts the leftmost end of the inclined surface or conical surface parts. After the position is adjusted, the position of the support arm 113 is fixed in the slide rail 111 by fasteners, and the inclined surface and conical surface parts are placed on the moving frame 127. The inclined surface or conical surface parts are fixed by the clamping unit 2, and the upper end surface thereof is abutted against the first linear displacement sensor 115, and the moving frame 127 is connected to the second linear displacement sensor 115 along one side of its length direction through the disc sleeve 126. The first threaded rod 124 is in contact with the first linear displacement sensor 128. At this time, the handle 125 is turned to rotate the first threaded rod 124. The rotation of the first threaded rod 124 causes the moving frame 127 and the disc sleeve 126 to move together toward the second linear displacement sensor 128. Both sides of the moving frame 127 match the raceways 122 of the boss 121, making it more stable during the movement. During this movement, the contacts of the first linear displacement sensor 115 and the second linear displacement sensor 128 will change, and the movement amount of the second linear displacement sensor 128 is the same as the movement amount of the first threaded rod 124. The displacement amount of the first linear displacement sensor 115 will also gradually increase.

[0037] It should be noted that the way in which the movable frame 127 abuts against the second linear displacement sensor 128 through the disc sleeve 126 along one side of its length direction can be regarded as the leftmost end of the inclined part or the conical part being in contact with the second linear displacement sensor 128, and thus can be regarded as the leftmost end of the inclined part or the conical part abutting against the first linear displacement sensor 115 and the second linear displacement sensor 128.

[0038] Reference Figure 3-Figure 7The lifting mechanism 21 includes a worm 211 rotatably arranged in the moving frame 127, and one end of the worm 211 passing through the moving frame 127 is fixedly connected with a turntable 212, and the turntable 212 can conveniently drive the worm 211 to rotate, and a worm wheel 213 is rotatably connected in the moving frame 127, and one end of the worm wheel 213 is meshed and connected with the worm 211, and a threaded sleeve 214 is fixedly connected to the worm wheel 213, and a second threaded rod 215 is arranged in the moving frame 127 through a bearing, and the second threaded rod 215 is threadedly connected with the threaded sleeve 214, and the second threaded rod 215 passes through the worm wheel 213, and a threaded hole 201 for avoiding the second threaded rod 215 is provided on the worm wheel 213, and the top of the second threaded rod 215 is connected to the clamping mechanism 22, and a locking member 20 is provided between the threaded sleeve 214 and the second threaded rod 215;

[0039] The locking member 20 includes a threaded hole 201 formed on the outer wall of the threaded sleeve 214 in the circumferential direction, a locking surface 202 is formed on the outer side of the second threaded rod 215, and a stopper 203 is inserted through the threaded hole 201 of the threaded sleeve 214 and fixedly abuts against the locking surface 202;

[0040] The clamping mechanism 22 includes a fixture bottom plate 221 connected to the top of the second threaded rod 215 through a bearing, a placement block 222 for fixing the inclined surface and the conical surface parts is rotatably connected to the fixture bottom plate 221, a bidirectional threaded rod 223 is rotatably connected inside the placement block 222, and clamping blocks 224 are threadedly connected at both ends of the bidirectional threaded rod 223, and two groups of V-shaped grooves 225 for clamping cylindrical workpieces are opened in the width direction of the two groups of clamping blocks 224, and a circular arc track 226 is opened on the fixture bottom plate 221, and both ends of the circular arc track 226 are fixedly connected to the first magnet 227;

[0041] A second magnet 228 is fixedly connected to the bottom of the placement block 222, and the second magnet 228 is slidably disposed in the arc track 226 and attracted to the first magnet 227;

[0042] When measuring angles on tapered parts:

[0043] like Fig.10As shown, the second magnetic block of the placement block 222 is manually rotated 90 degrees in the circular arc track 226 to make it parallel to the side of the base 100. The second magnetic block is cylindrical and is slidably arranged in the circular arc track 226 to increase the stability of the placement block 222. Furthermore, the second magnetic block is magnetic, and both ends of the circular arc track 226 are fixedly connected with the first magnetic block. The mutual attraction between the first magnetic block and the second magnetic block can further increase the stability of the placement block 222. The conical part is placed in the V-groove 225 of the clamping block 224 for clamping, and the distance between the two groups of clamping blocks 224 is adjusted according to the length of the conical part, so that the conical part can be fixed;

[0044] When measuring the angle of an inclined part:

[0045] like Fig. 9 As shown, the placement block 222 is positioned perpendicular to the side of the base 100, the inclined surface part is placed between the two clamping blocks 224, and the side wall of the inclined surface part is clamped and fixed by the clamping blocks 224;

[0046] When measuring, according to the different inclined parts or conical parts, the above-mentioned different clamping methods are used to adjust the position of the clamping block 224. After the position is adjusted, by rotating the turntable 212, the worm wheel 213 and worm 211 mechanism are operated to rotate the worm 211 to transmit the rotation to the worm wheel 213, so that the rotation of the worm wheel 213 drives the threaded sleeve 214 to rotate, thereby driving the second threaded rod 215 to rotate, and use the hand to limit the second threaded rod 215 during its rotation, until the clamp base 100 is driven to rise and fall to a suitable height and then stop. Since the worm wheel 213 and worm 211 have a self-locking function, the workpiece is stabilized at a certain height. Furthermore, in order to increase the stability of the lifting height, a stop block 203 is fixedly connected between the threaded sleeve 214 and the second threaded rod 215. After all these preparations are ready, the above-mentioned lateral distance operation is performed to obtain the lateral displacement and longitudinal displacement of the workpiece, and the angle of the workpiece is obtained after calculation.

[0047] How this application works:

[0048] When measuring the angle of an inclined part:

[0049] Make the placement block 222 perpendicular to the side of the base 100, place the inclined surface part between the two clamping blocks 224, and use the clamping blocks 224 to clamp and fix the side wall of the inclined surface part;

[0050] When measuring angles on tapered parts:

[0051] The second magnetic block of the placement block 222 is rotated 90 degrees in the arc track 226 to make it parallel to the side of the base 100. The second magnetic block is cylindrical and is slidably arranged in the arc track 226 to increase the stability of the placement block 222. Furthermore, the second magnetic block is magnetic, and both ends of the arc track 226 are fixedly connected with the first magnetic block. The mutual attraction between the first magnetic block and the second magnetic block can further increase the stability of the placement block 222. The conical part is placed in the V-groove 225 of the clamping block 224 for clamping, and the distance between the two groups of clamping blocks 224 is adjusted according to the length of the conical part, so that the conical part can be fixed;

[0052] Adjust the height. After adjusting the position, adjust the height of the inclined surface or conical workpiece by rotating the turntable 212 and operating the worm gear 213 and worm 211 mechanism;

[0053] After measuring the lateral and longitudinal distances and adjusting the height of the workpiece, the values ​​of the first linear displacement sensor 115 and the second linear displacement sensor 128 are adjusted to zero. At this time, the handle 125 is rotated to rotate and move the first threaded rod 124 in the fixed block 123, and the moving frame 127 and the disc sleeve 126 are driven to move toward the direction of the second linear displacement sensor 128. The disc sleeve 126 contacts the contact of the second linear displacement sensor 128 and forces it to move. This displacement is consistent with the displacement of the workpiece lateral movement, and as the workpiece moves lateral, the contact of the first linear displacement sensor 115 is also displaced, and the angle is calculated based on the amount of lateral and longitudinal displacement.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0055] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
