Description

Technical Field

[0001] This utility model relates to the field of nut measurement technology, specifically a nut wall thickness measuring device. Background Technology

[0002] Accurate measurement of nut wall thickness is a crucial step in ensuring product compliance with design standards. Some portable nut wall thickness measuring devices indirectly calculate the nut wall thickness by measuring the vertical distance between the probe tip and a reference surface (such as a marble base). Compared to existing large measuring equipment, these devices offer advantages such as lower cost, ease of operation, and portability, and are therefore widely used in actual production. To ensure stability and accuracy during measurement, most devices employ a one-piece base design, where the base is made of a single piece of marble. This base improves the device's stability but makes storage inconvenient. Utility Model Content

Therefore, they should not be construed as limitations on this patent.

[0032] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "assembly" should be interpreted broadly. For example, they can refer to a fixed connection or installation, a detachable connection or installation, or an integral connection or installation. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0033] Please refer to Figures 1 to 4 One embodiment discloses a nut wall thickness measuring device, the structure of which includes a base 1, a support member 2 with a limiting member arranged on its surface; a height gauge 3 is arranged to connect the limiting member, and the support member 2 is configured to adjust the position of the height gauge 3; wherein, the base 1 includes six plates 11, the plates are arranged in a rectangular shape, and in a first state, all plates 11 are located in the same plane and are spliced ​​together to form an integral splice, forming a first space.

[0034] Specifically, the measuring device includes a base 1, a support component 2, and a height gauge 3. The base 1 is composed of six rectangular plates 11 forming a detachable and reconfigurable structure. The plates 11 are connected by snap-fits or bolts to achieve assembly and disassembly. This application does not specify any particular method. Figure 3 As shown, in the unfolded state, the six plates are in the same plane, and the edges of adjacent plates are fixed by a snap-fit ​​or bolt fastener structure, forming a complete measurement reference surface, as shown. Figure 4 As shown, when storage is required, six pieces of board 11 are assembled into a box to form a closed storage space. The support member 2 and the height gauge 3 can be placed in the box for transportation. The support member 2 is connected to the height gauge 3 through a limiting member. The position of the height gauge 3 can be adjusted through the support member 2 so that the tip of the height gauge probe can accurately contact the root of the nut thread. In this embodiment, the specific structure of the support member 2 is not limited. Optionally, the transmission part of the support member 2 is composed of a precision lead screw and a slide rail. The support member 2 measures the nut thickness based on the vertical distance difference between the probe tip and the reference surface (base). During measurement, the nut is placed on the base, and the support member is adjusted so that the probe tip contacts the root of the nut thread. The initial reading H1 of the height gauge is recorded at this time. Then, the probe is moved to the outer end face of the nut, and the second reading H2 is recorded. The nut wall thickness T can be calculated by the formula T=H1-H2. In order to control the measurement error, in one embodiment, the probe tip is arranged with rounded corners (R≤0.1mm). When in contact with the root of the nut thread, the contact point is as close as possible to the root of the thread. In one embodiment, the first space is arranged in a cube.

[0035] Please continue to refer to this. Figure 1 and Figure 2 In one embodiment, the support member 2 includes a first support portion vertically connected to the base 1 and a second support portion vertically connected to the first support portion. The surface of the first support portion is provided with a first groove along a first direction, and the second support portion is slidably connected to the first groove. The surface of the second support portion is provided with a second groove along a second direction, and the second groove is slidably connected to a second slider. The second slider is fixedly connected to a limiting member, and the first direction is perpendicular to the second direction.

[0036] Specifically, the first support and the second support are vertically connected to form an L-shaped spatial structure. The bottom surface of the first support is vertically connected to the base by bolts or other fasteners. The upper surface of the first support has a first groove arranged along the first direction. The second support slides along the first groove in the first direction. In one embodiment, a locking mechanism (such as screws, buckles, etc.) is provided to lock the positions of the first and second support. Those skilled in the art will understand this and will not be described further here. The surface of the second support has a second groove arranged along the second direction. The limiting member slides along the second groove in the second direction and the position of the limiting member is fixed by the locking mechanism.

[0037] Please refer to Figure 2 and Figure 4 In one embodiment, the altimeter 3 includes a housing 31 and a probe located at the end of the housing 31. The probe includes a first segment perpendicular to the base 1, a second segment connected to the first segment at one end and arranged parallel to the base 1, and a third segment connected to the second segment at one end and arranged perpendicular to the base 1; wherein the length of the first segment is greater than the length of the third segment.

[0038] Specifically, the probe uses a three-section structure to adapt to the complex and varied geometry of the nut's inner wall. The first section of the probe extends perpendicularly to the base, such as... Figure 2 As shown, segment a is the first segment, segment b is the second segment, and segment c is the third segment. Please refer to this. Figure 5 The third segment contacts the inner wall of the nut after the probe reaches a specific position on the inner wall, and performs precise wall thickness measurement. The third segment is relatively short, which can flexibly meet the size requirements of the nut. For some smaller nuts, the probe can also extend to its inner wall. In one embodiment, the length of the third segment is 1-4cm, and the length of the first segment is greater than 5cm.

[0039] like Figure 7 As shown, in one embodiment, the altimeter 3 further includes a display component 32, which is fixedly connected to the housing 31 and is used to display the data measured by the probe.

[0040] Please refer to Figure 2 and Figure 6 In one embodiment, a clamping member 4 is arranged on the surface of the base 1. The clamping member 4 includes a first arm 41 vertically connected to the base 1, a second arm 42 vertically arranged on the first arm 41, a third sliding groove arranged on the surface of the second arm 42, and a block 43 slidably connected to the third sliding groove. The first arm 41 is made of magnetic metal, and the block 43 is made of electromagnet. The clamping member 4 is used to limit the position of the nut to be detected, placing a portion of the nut's side area at the gap between the first arm 41 and the block 43. By controlling the energization state of the electromagnet, the nut can be clamped or released. When the electromagnet is energized, the magnetic force between the block 43 and the first arm 41 is enhanced, and the nut is firmly clamped; when the electromagnet is de-energized, the magnetic force disappears, and the nut can be easily removed from the clamping member 4.

[0041] In one embodiment, through holes 12 are arranged at the corners of the plate 11. Specifically, when the plate 11 is in its current planar state, i.e., before it is assembled into a box, a sheet-like connector can be used. The sheet-like connector also has holes corresponding to the through holes in the plate. By attaching the sheet-like connector to the corner of the plate and aligning the holes, bolts are passed through these holes and tightened with nuts, thereby achieving a firm connection between the plates. When the plates need to be assembled into a box, L-shaped connectors can be used. Figure 7 The middle component is an L-shaped connector, which can simultaneously fit the corner of two adjacent panels, and both arms have holes corresponding to the through holes in the panels. During assembly, the L-shaped connector is placed at the corner where the two panels meet, ensuring all holes are aligned, and then tightened with bolts and nuts.

[0042] In summary, this utility model discloses a nut wall thickness measuring device, the structure of which includes a base 1, a support component 2, and a height gauge 3. The base 1 is composed of six rectangular plates 11, adopting a detachable and reconfigurable design. The plates are connected by snap-fit ​​or bolts to achieve assembly and disassembly. When unfolded, the six plates are on the same plane, and the edges of adjacent plates are fixed by snap-fit ​​or bolt fasteners to form a complete measurement reference surface. When stored, the six plates can be assembled into a box to form a closed storage space, facilitating the placement and transportation of the support component 2 and the height gauge 3. The support component 2 has limiting components arranged on its surface, which are connected to the height gauge 3. The position of the height gauge 3 can be adjusted through the support component 2, so that the tip of the height gauge probe accurately contacts the root of the nut thread. The device in this application achieves convenient assembly of the measuring device through modular design, while ensuring accuracy during the measurement process.

[0043] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
