Description

Technical Field

[0001] The utility model belongs to the technical field of angle detection, and in particular relates to an angle detection device. Background Art

[0002] Typically, the engine's rotor housing is equipped with a convex bump. During rotor rotation, the bump contacts a trigger extending from the stator, generating current and an ignition signal. In existing technology, the angle between the center of the bump and the center of the rotor's keyway is typically 50-60 degrees. This not only prevents engine vibration during acceleration but also effectively improves the reliability of the ignition signal.

[0003] In actual rotor production, a dial is typically used in conjunction with manual reading of these angles. The readings are then used to determine whether the rotor meets quality requirements, thereby achieving quality inspection. However, this dial-based manual approach presents the following problems: First, manual readings are affected by factors such as viewing angle, lighting, and positioning, resulting in inaccurate readings that can affect subsequent engine operation; second, it is inefficient and cannot meet the needs of large production volumes. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an angle detection device to solve the technical problem of inaccurate readings of the manual indexing disk in the prior art.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0007] Furthermore, a third limiting ring is sleeved on the outer surface of the lower cylinder;

[0008] Furthermore, the extension direction of the slide rail is consistent with the length direction of the table;

[0009] Furthermore, a first limiting ring and a second limiting ring are horizontally arranged in the mounting hole from top to bottom along the height direction, wherein the upper surface of the first limiting ring coincides with the upper surface of the table plate, and the lower surface of the second limiting ring coincides with the lower surface of the table plate, and the outer side surfaces of the first limiting ring and the second limiting ring are fixed to the inner side surface of the mounting hole; a bearing is installed at the interval between the first limiting ring and the second limiting ring, the inner diameter of the first limiting ring is consistent with that of the bearing and the inner diameter of the first limiting ring is smaller than the inner diameter of the second limiting ring, and the outer side surface of the bearing is fixedly connected to the inner side surface of the mounting hole;

DETAILED DESCRIPTION

[0026] Example 1, specifically as Figures 1-9 shown.

[0027] like Figure 1 As shown, an angle detection device includes a workbench 1 and a rotating base 2 arranged on the workbench 1, and a positioning mechanism 3 is provided on one side of the rotating base 2 facing the rotating base 2.

[0028] The rotating base 2 includes a base body 21. In this embodiment, the base body 21 is composed of an upper cone 211 and a lower cylinder 212, which are integrally formed. The bottom surface dimensions of the upper cone 211 are consistent with the cross-sectional dimensions of the lower cylinder 212. An elongated limit key 213 is welded to the side of the upper cone 211. In this embodiment, the limit key 213 extends from the top surface of the upper cone 211 to the bottom surface of the upper cone 211. The workbench 1 includes a tabletop 11 and support legs 12. A through-type mounting hole 13 is provided at the center of the tabletop 11. The diameter of the mounting hole 13 is larger than the diameter of the lower cylinder 212.

[0029] A first limiting ring 22 and a second limiting ring 23 are horizontally arranged in the mounting hole 13 from top to bottom along the height direction. The upper surface of the first limiting ring 22 coincides with the upper surface of the table 11, and the lower surface of the second limiting ring 23 coincides with the lower surface of the table 11. The outer side surfaces of the first limiting ring 22 and the second limiting ring 23 are welded to the inner side surface of the mounting hole 13. A bearing 24 is installed in the gap between the first limiting ring 22 and the second limiting ring 23. The inner diameter of the first limiting ring 22 and the bearing 24 is the same, and the inner diameter of the first limiting ring 22 is smaller than the inner diameter of the second limiting ring 23. The outer side surface of the bearing 24 is fixedly connected to the inner side surface of the mounting hole 13 by welding.

[0030] The diameter of the lower cylinder 212 of the seat body 21 is consistent with the inner diameter of the first limiting ring 22. The lower cylinder 212 partially extends into the mounting hole 13 until the bottom surface of the lower cylinder 212 contacts the upper surface of the second limiting ring 23. The side surface of the lower cylinder 212 is welded to the inner side surface of the bearing 24, thereby realizing the rotational connection between the seat body 21 and the table plate 11.

[0031] The positioning mechanism 3 includes a slide rail 31. In this embodiment, the extension direction of the slide rail 31 is consistent with the length direction of the table 11. The slide rail 31 is fixedly connected to the upper surface of the table 11 by screws. A slider 32 is slidably connected to the slide rail 31. A fixing block 33 is threadedly fixed to the upper surface of the slider 32. A slot 34 is welded to the side of the fixing block 33 facing the rotating base 2. By providing a detachable connection between the fixing block 33 and the slider 32, the slot 34 of different sizes can be replaced as needed.

[0032] An angle sensor 5 for measuring the rotation angle of the base 21 is provided below the base 21. The angle sensor 5 is fixedly connected to the lower surface of the table 11 by screws. A display 6 and a power supply 7 are provided at the end of the table 11 away from the positioning mechanism 3. The display 6 is mounted above the table 11, wherein the power supply 7 is electrically connected to the angle sensor 5 and the display 6 respectively. The power supply 7 is transformed by the power supply 7 to supply power to the angle sensor 5 and the display 6. The angle sensor 5 is electrically connected to the display 6, and the angle measurement value is displayed in real time on the display 6. It is worth emphasizing that when the base 21 is rotated to the point where the limit key 213 is aligned with the slot 34, it is in the initial state, with an angle of 0°. As the base 21 rotates counterclockwise, the angle gradually increases, and the angle range is 0-360°.

[0033] like Figure 2 As shown, a third limiting ring 25 is sleeved on the outer surface of the lower cylinder 212. In this embodiment, the bottom surface of the third limiting ring 25 contacts the upper surface of the first limiting ring 22, and the top surface of the third limiting ring 25 coincides with the top surface of the lower cylinder 212.

[0034] In this embodiment, the rotor 4 includes a shell 41 and a sleeve 42 riveted to the shell 41. A keyway 43 compatible with the limit key 213 is provided on the inner side surface of the sleeve 42. A bulge 44 is formed on the side surface of the shell 41 by stamping. It is particularly important to note that the angle between the center of the bulge 44 and the center of the keyway 43 is a fixed value. In this embodiment, the setting range of the fixed value is 50-60° to ensure the reliability of the ignition signal.

[0035] When in use, first, the rotor shell 4 is sleeved on the base body 21, that is, the limit key 213 on the base body 21 is matched with the keyway 43 on the inner side of the sleeve 42. At this time, the end of the sleeve 42 is against the third limit ring 25, and a gap is left between the shell 41 and the table 11, and the height of the gap is greater than the height of the slide rail 31; then, the shell 41 is rotated. During the rotation process, the angle sensor 5 transmits a signal to the display 6 in real time, and the display 6 displays the angle size. When the convex 44 is facing the slot 34, the slider 32 is slid, and the slot 34 slides toward the convex 44, and the convex 44 is snapped into the slot 34 to fix the rotor 4. At this time, the final measurement value displayed on the display 6 is the angle between the center of the convex 44 and the center of the keyway 43. By comparing the final measurement value with the set range (50-60°), it is determined whether the rotor 4 meets the production quality requirements.

[0036] By using the rotating seat 2, the positioning mechanism 3, the angle sensor 5 and the like in combination, on the one hand, compared with manual reading, the angle measured by the angle sensor 5 is more accurate and can display the angle value, thereby avoiding the error caused by manual detection, improving the accuracy of angle detection, and accelerating the detection speed and production efficiency; on the other hand, replacing manual reading reduces the labor intensity of production personnel.

[0037] In addition, since there is a gap between the shell 41 and the table 11, and the height of the gap is greater than the height of the slide rail 31, the angle detection of shells 41 with different diameters can be met, thereby improving the applicability of the entire detection equipment.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
