Description

Technical Field

[0001] The present application relates to the technical field of mechanical measurement, and in particular to a plane inclination detector. Background Art

[0002] Traditional plane inclination detection devices are mostly complex measuring equipment such as electronic measuring instruments or simple measuring tools such as bubble levels. Electronic measuring instruments are expensive and cumbersome to operate, while the bubble level's ability to detect the inclination of a plane is far less than 1°, its detection range is small, and it cannot directly read the inclination, requiring inverse trigonometric function calculations. Not only is the operation cumbersome, the measurement accuracy is also low. Therefore, existing plane inclination detection devices are difficult to take into account both measurement accuracy and equipment cost at the same time, and are less practical. Utility Model Content

[0003] The main purpose of the present application is to provide a plane inclination detector, aiming to solve the technical problem that the existing plane inclination detection devices are difficult to take into account both measurement accuracy and equipment cost and have low practicality.

[0004] To achieve the above-mentioned purpose, the present application provides a plane inclination detector, including a detection bracket, a mounting shaft, a gravity rotating component, a pointer and a dial. The bottom surface of the detection bracket is a contact plane that contacts the plane to be detected. The detection bracket has four side surfaces, and the adjacent side surfaces of the detection bracket are perpendicular to each other. The side surfaces of the detection bracket are vertically connected to the mounting shaft, and the gravity rotating components are movably mounted on the mounting shaft. The top of the gravity rotating components is connected to the pointer, and the side surfaces of the detection bracket are provided with dials, which are used to cooperate with the pointer.

[0005] Optionally, the gravity rotating assembly includes a rotating ring, a connecting rod and a gravity block, the rotating ring is movably sleeved on the mounting shaft, the pointer is connected to the top of the rotating ring, the connecting rod is connected to the bottom of the rotating ring, and the gravity block is connected to the bottom of the connecting rod.

[0006] Optionally, the gravity block is spherical.

[0007] Optionally, the sides of the detection bracket are provided with mounting grooves matching with the scale plate, and the scale plate can be detachably mounted in the mounting grooves.

[0008] Optionally, at least one limiting nut is provided on the threaded sleeve on the mounting shaft, and the rotating ring is located between the limiting nut and the side surface of the detection bracket.

[0009] Optionally, mounting holes cooperating with the mounting shaft are provided on the sides of the detection bracket, and a retaining spring for limiting the axial movement of the mounting shaft is provided in the mounting hole.

[0010] Optionally, the interior of the detection bracket is a hollow structure.

[0011] Optionally, a handle is provided on the top of the detection bracket.

[0012] The beneficial effects that this application can achieve are as follows:

[0013] The present application includes a detection bracket, a mounting shaft, a gravity rotating component, a pointer and a dial. The bottom surface of the detection bracket is a contact plane in contact with the plane to be detected. The detection bracket has four sides, and the adjacent sides of the detection bracket are perpendicular to each other. The sides of the detection bracket are vertically connected to the mounting shaft, and the gravity rotating component is movably mounted on the mounting shaft. The top of the gravity rotating component is connected to the pointer. The sides of the detection bracket are provided with a dial, and the dial is used to cooperate with the pointer. Based on the structure of the present application, during detection, the entire detector is placed on the plane to be detected through the contact plane. When the detector is in an inclined state as a whole, the two gravity rotating components on the opposite sides of the detection bracket naturally droop under the action of gravity, that is, the pointer always remains vertical to the horizontal ground, and the dial rotates relative to the pointer when the detector is tilted, so that the inclination readings of the two pointers and the dial corresponding to the opposite sides can be read, and the readings of the dials 150 on the other two adjacent opposite sides are observed at the same time. If the reading is not zero, there is no intuitive way to detect the inclination. In this case, the detector needs to be rotated in the placement direction until the reading of the set of opposite dials 150 is 0, then the reading of the other pair of opposite dials 150 that is not zero is the inclination reading, and the bottom placement direction of the set of opposite dials 150 that is not zero is the inclination direction, thereby ensuring the measurement accuracy. At the same time, the present application can utilize the mechanical measurement principle that the gravity of the gravity rotating component is always vertically downward to achieve precise measurement, and the cost is lower than that of electronic measuring instruments. Therefore, the present application can take into account both the inclination measurement accuracy and the equipment cost, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] Reference Figure 1-Figure 3 The present embodiment provides a plane inclination detector, including a detection bracket 110, a mounting shaft 120, a gravity rotation component 130, a pointer 140 and a dial 150. The bottom surface of the detection bracket 110 is a contact plane that contacts the plane to be detected. The detection bracket 110 has four side surfaces, and the adjacent side surfaces of the detection bracket 110 are perpendicular to each other. The side surfaces of the detection bracket 110 are vertically connected to the mounting shaft 120. The gravity rotation component 130 is movably mounted on the mounting shaft 120. The top of the gravity rotation component 130 is connected to the pointer 140. The side surfaces of the detection bracket 110 are provided with a dial 150, and the dial 150 is used to cooperate with the pointer 140.

[0027] In this embodiment, during detection, the entire detector is placed on the plane to be detected through the contact plane. When the detector is in a tilted state as a whole, the two gravity rotating components 130 on the opposite sides of the detection bracket 110 naturally droop under the action of gravity, that is, the pointer 140 always remains vertical to the horizontal ground, and the dial 150 rotates relative to the pointer 140 as the detector tilts, so that the inclination readings of the two pointers 140 and the dial 150 corresponding to the opposite sides can be read, and the readings of the dials 150 on the other two adjacent opposite sides are observed at the same time. If the reading is not zero, the direction of the inclination cannot be detected intuitively, and the placement direction of the detector needs to be rotated until the group is If the reading of the opposite surface dial 150 is 0, then the reading of the other pair of opposite surface dials 150 that is not zero is the inclination reading, and the direction in which the bottom of the pair of opposite surface dials 150 with non-zero readings is placed is the inclination direction, thereby ensuring the measurement accuracy. At the same time, this embodiment can use the mechanical measurement principle that the gravity of the gravity rotating component 130 is always vertically downward to achieve precise measurement, and its cost is lower than that of electronic measuring instruments. Therefore, this embodiment can take into account both the inclination measurement accuracy and the equipment cost, thereby improving practicality. It can be applied to fields such as robot operation, workpiece processing positioning, equipment installation and leveling, and physical experiments, and can realize efficient and accurate detection of the plane inclination direction and angle.

[0028] It should be noted that when observing the inclination readings of the two pointers 140 and the dial 150 on the opposite surfaces, it is possible to observe whether the two inclination readings are completely consistent (generally they are consistent). If there is a slight difference, the average value of the two can be taken as the final inclination reading, thereby further ensuring the measurement accuracy; the design of the dial 150 allows the user to select different accuracy levels according to needs, such as 1°, 0.5°, 0.25°, 0.1°, etc., and the radius of the dial 150 can be selected according to needs. The larger the radius, the higher the resolvable reading accuracy, so as to meet the accuracy requirements of different application scenarios; the accuracy levels of the dials 150 on the opposite surfaces should be the same, so that the alignment degree of the inclination direction of the detector and the plane to be detected can be corrected and adjusted according to whether the two inclination readings are the same, and the accuracy levels of adjacent dials 150 may be different, so that two dials 150 of corresponding accuracy levels can be selected as detection surfaces according to actual accuracy requirements.

[0029] As an optional embodiment, the gravity rotation assembly 130 includes a rotating ring 131, a connecting rod 132 and a gravity block 132. The rotating ring 131 is movably mounted on the mounting shaft 120, the pointer 140 is connected to the top of the rotating ring 131, the connecting rod 132 is connected to the bottom of the rotating ring 131, and the gravity block 132 is connected to the bottom of the connecting rod 132.

[0030] In this embodiment, when the detector is placed on an inclined plane to be detected, the rotating ring 131 rotates on the mounting shaft 120 under the action of the gravity of the gravity block 132, and the connecting rod 132 also swings until the pointer 140 on the rotating ring 131 stably points to the corresponding reading on the dial 150, thereby realizing mechanical automatic measurement and accurate measurement.

[0031] It should be noted that the rotating ring 131, the connecting rod 132 and the gravity block 132 can be an integrally connected structure, or they can be respectively threadedly connected to the rotating ring 131 and the gravity block 132 through the connecting rod 132, which is convenient for disassembly and assembly to replace some parts according to needs, and is more flexible to use; similarly, the pointer 140 can be integrally connected to the rotating ring 131, or it can be detachably connected to the rotating ring 131 by means of threads or snap-on, which is convenient for separately replacing the deformed or damaged pointer 140, thereby improving the utilization rate of the detector; the rotating ring 131 can be directly mounted on the mounting shaft 120, or it can be mounted on the mounting shaft 120 through a roller sleeve, which can reduce wear.

[0032] As an optional embodiment, the gravity block 132 is spherical with a smooth surface that is not easily damaged, thereby avoiding the risk of damage caused by using a block with sharp corners.

[0033] As an optional implementation, the sides of the detection bracket 110 are provided with installation grooves that match the dial 150, and the dial 150 can be detachably installed in the installation grooves.

[0034] In this embodiment, since the dial 150 can be removably installed in the installation groove, the accuracy setting can be adjusted according to actual needs. That is, by replacing the inclination disk 150 of different sizes, the adjustment of different measurement accuracies can be achieved, thereby improving the utilization rate. There is no need to separately manufacture multiple detectors with different measurement accuracies, thereby improving versatility.

[0035] It should be noted that the scale plate 150 and the mounting groove can be adsorbed by magnets, or can be bonded or snapped together, so that they are not easy to fall off after installation.

[0036] As an optional embodiment, at least one limiting nut 160 is threadedly sleeved on the mounting shaft 120, and the rotating ring 131 is located between the limiting nut 160 and the side of the detection bracket 110. The limiting nut 160 can prevent the rotating ring 131 from being separated from the mounting shaft 120, and at the same time facilitate disassembly and assembly.

[0037] As an optional embodiment, the side of the detection bracket 110 is provided with a mounting hole that cooperates with the mounting shaft 120, and a retaining spring 170 is provided in the mounting hole for limiting the axial movement of the mounting shaft 120. The mounting shaft 120 is detachably connected to the side of the detection bracket 110 through the mounting hole, which is convenient for assembly. At the same time, the retaining spring 170 can prevent the axial movement of the mounting shaft 120.

[0038] As an optional implementation, the interior of the detection bracket 110 is a hollow structure, so that the detection bracket 110 is lighter, easier to carry, and saves material costs.

[0039] As an optional implementation, a handle (not shown) is provided on the top of the detection bracket 110, so as to facilitate carrying the entire detector by the handle and also facilitate subsequent hoisting and use.

[0040] In summary, the detector in this embodiment has the following characteristics and advantages:

[0041] (1) Wide applicability: Applicable to a variety of industrial and laboratory scenarios, including but not limited to robot grasping, workpiece processing, equipment installation and other fields.
