Description

Technical Field

[0001] This application relates to the field of testing tooling technology, and in particular to an auxiliary testing tooling and testing equipment. Background Technology

[0002] One side of the server rack has a cable tray, which serves to support and manage cables. Excessive force applied when plugging or unplugging cable connectors from server nodes can cause the cable tray to deform. To prevent excessive deformation that could lead to the cable trays failing to support the cables properly, the flatness of the cable trays in the server rack needs to be measured periodically.

[0003] In related technologies, the flatness of cable trays on server racks is measured using measuring instruments (such as digital dial indicators, distance sensors, etc.). The operator holds the measuring instrument, aligns it with the surface of the cable tray to be measured, and then moves the instrument vertically and horizontally. The measuring instrument performs multi-point checks at different locations on the surface of the cable tray to determine whether it meets the specified flatness requirements.

[0004] However, the above methods are inefficient and inconvenient for manual measurement. Utility Model Content

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0048] The terms “first,” “second,” “third,” and “fourth,” etc. (if present), in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0049] As mentioned in the background section, in related technologies, the flatness of cable trays on server racks is measured using measuring instruments (such as digital dial indicators, distance sensors, etc.). The operator holds the measuring instrument, aligns it with the surface of the cable tray to be measured, and then moves the measuring instrument vertically and horizontally. The measuring instrument performs multi-point checks at different locations on the surface of the cable tray to determine whether it meets the specified flatness requirements.

[0050] However, the above methods are inefficient and inconvenient for manual measurement.

[0051] Due to the height limitations of server racks, operators at higher measurement positions need to frequently adjust their posture and angle while holding the measuring instrument. This is not only physically demanding but also prone to errors in measurement data, reducing measurement accuracy.

[0052] To address the aforementioned problems in the existing technology, this utility model provides an auxiliary testing fixture and testing equipment. The auxiliary testing fixture includes a first sliding member, a second sliding member, and a mounting assembly. The first sliding member is mounted to the entire equipment. The second sliding member is slidably connected to the first sliding member. The mounting assembly is slidably connected to the second sliding member and is used to mount a measuring instrument. The mounting assembly is configured to move vertically under the action of the first sliding member and horizontally under the action of the second sliding member when the measuring instrument is aligned with the workpiece to be measured on the entire equipment. By directly mounting the first sliding member to the entire equipment, the measuring instrument can perform flatness measurement on the workpiece on the entire equipment without removing the workpiece from the entire equipment, thus improving the convenience of measurement. Furthermore, the mounting assembly, driven by the first and second sliding members, enables the measuring instrument to complete measurements at multiple positions on the workpiece, saving manual labor and improving measurement efficiency.

[0053] The following describes exemplary application scenarios of this utility model.

[0054] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0055] Reference Figures 1 to 7 As shown in the embodiment of this application, the auxiliary testing fixture includes a first slider 100, a second slider 200, and a mounting assembly 300.

[0056] The first sliding member 100 is used to be mounted on the entire equipment. The second sliding member 200 is slidably connected to the first sliding member 100. The mounting assembly 300 is slidably connected to the second sliding member 200 and is used to mount the measuring instrument. The mounting assembly 300 is configured to move vertically under the action of the first sliding member 100 and horizontally under the action of the second sliding member 200 when the measuring instrument is aligned with the part to be measured 10 on the entire equipment.

[0057] It is understood that the auxiliary testing fixture provided in this application embodiment can assist the measuring instrument in measuring the flatness of the part to be measured 10 on the entire equipment. The entire equipment can be a server rack or other large equipment, and the part to be measured 10 can be a cable tray on the server rack or other objects to be measured. The measuring instrument can be a digital dial indicator, a distance sensor, etc.

[0058] Reference Figure 1 and Figure 7 As shown, before performing flatness measurement, the first sliding member 100 can be installed on the entire equipment, and the measuring instrument can be installed on the mounting assembly 300. Before starting the measurement, the measuring instrument is aligned with the part to be measured 10 and zeroed.

[0059] During measurement, the first sliding member 100 drives the second sliding member 200 and the measuring instrument to move together in the vertical direction, and the second sliding member 200 drives the measuring instrument to move in the horizontal direction, so that the measuring instrument moves on the plane formed by the vertical and horizontal directions. The measuring instrument collects data of the part to be measured 10 in real time and records the measurement values ​​at different positions. Based on the flatness error of the measurement, it is determined whether the part to be measured 10 meets the technical requirements.

[0060] In this design, by directly mounting the first sliding member 100 onto the entire equipment, the measuring instrument can be used to measure the flatness of the workpiece 10 on the equipment. This eliminates the need to remove the workpiece 10 from the equipment, improving the convenience of the measurement. Furthermore, the mounting assembly 300, driven by the first sliding member 100 and the second sliding member 200, enables the measuring instrument to measure multiple positions of the workpiece 10, saving manual labor and improving measurement efficiency.

[0061] To facilitate understanding of the directions, an XYZ spatial coordinate system is established in the accompanying drawings of the relevant specification. The X-axis is the vertical direction as indicated in the embodiments of this application, the Y-axis is the horizontal direction as indicated in the embodiments of this application, and the Z-axis is the extension direction as indicated in the embodiments of this application.

[0062] In summary, the auxiliary testing fixture provided in this application embodiment, by directly mounting the first sliding member 100 onto the entire equipment, assists the measuring instrument in measuring the flatness of the workpiece 10 on the entire equipment. This eliminates the need to remove the workpiece 10 from the entire equipment, thus improving the convenience of measurement. Furthermore, the mounting assembly 300, driven by the first sliding member 100 and the second sliding member 200, enables the measuring instrument to complete measurements at multiple positions of the workpiece 10, saving manual labor and improving measurement efficiency.

[0063] Reference Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, at least one of the first slider 100 and the second slider 200 includes a slide rail portion 120 and a slider portion 130. The slider portion 130 is slidably disposed on the slide rail portion 120.

[0064] Among them, reference Figure 2 and Figure 4 As shown, both the first slider 100 and the second slider 200 may include a slide rail portion 120 and a slider portion 130. The slide rail portion 120 of the second slider 200 is disposed on the slider portion 130 of the first slider 100, and the mounting assembly 300 is disposed on the slider portion 130 of the second slider 200. The slide rail portion 120 of the first slider 100 extends vertically, and the slide rail portion 120 of the second slider 200 extends horizontally.

[0065] In the above embodiment, the slider 130 slides on the slide rail 120 to make the measuring instrument move in the vertical and horizontal directions, thereby realizing the flatness measurement.

[0066] The slider 130 can be manually slid or driven by an electric drive unit; there are no specific limitations on this.

[0067] Reference Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the auxiliary testing fixture provided in this application also includes a limiting member 400. The limiting member 400 is connected to the slider portion 130 of the first slider 100. The limiting member 400 is configured to be connected to the slide rail portion 120 of the first slider 100 so as to limit the slider portion 130 of the first slider 100 to the slide rail portion 120 of the first slider 100.

[0068] In the above embodiment, when the second slider 200 moves vertically to a specified height position, the limiting member 400 can limit the slider portion 130 of the first slider 100 to the slide rail portion 120 of the first slider 100, restricting the second slider 200 from continuing to move. Then, the slider portion 130 of the second slider 200 is slid to collect data from multiple collection points at the specified height position using a measuring instrument. Afterward, the limiting member 400 is released from the restriction on the slider portion 130 of the first slider 100, and the second slider 200 moves vertically to the next position to continue the data collection.

[0069] In this way, by setting the limiting component 400, the second sliding component 200 is prevented from sliding off due to gravity when the measuring instrument slides on the second sliding component 200, thus avoiding measurement inconvenience.

[0070] For example, the limiting member 400 can be a clamping and limiting structure, which clamps the slide rail portion 120 of the first sliding member 100 to achieve a limiting function; the limiting member 400 can also be a pin structure, which is inserted into a plurality of positioning holes spaced apart on the slide rail portion 120 of the first sliding member 100 to achieve a limiting function. The embodiments of this application do not impose too many limitations on this.

[0071] Reference Figures 4 to 6 As shown, in some embodiments, the limiting member 400 includes a main body 410, a first clamping part 420, a second clamping part 430, and a driving part 440. A portion of the driving part 440 is inserted into the slide groove 411 and connected to the first clamping part 420 and the second clamping part 430 respectively. The driving part 440 is configured to drive the first clamping part 420 and the second clamping part 430 to move closer or further apart, thereby clamping or releasing the slide rail part 120 of the first sliding member 100.

[0072] In the above embodiment, under the action of the driving unit 440, the first clamping part 420 and the second clamping part 430 can slide within the slide groove 411 of the main body part 410 and move closer to each other, thereby clamping the slide rail part 120 of the first slider 100 to limit the slider part 130 of the first slider 100 to the slide rail part 120 of the first slider 100. The first clamping part 420 and the second clamping part 430 can also move away from each other under the action of the driving unit 440, thereby releasing the slide rail part 120 of the first slider 100 so that the slider part 130 of the first slider 100 can continue to slide on the slide rail part 120 of the first slider 100.

[0073] For example, refer to Figure 6As shown, the drive part 440 can be a screw, the first clamping part 420 is a first nut, and the second clamping part 430 is a second nut. The screw has a bidirectional first threaded section and a second threaded section. The first nut is threadedly connected to the first threaded section, and the second nut is threadedly connected to the second threaded section. In this way, by rotating the screw, the first nut and the second nut can be moved closer to each other or further away from each other, so as to clamp or release the slide rail part 120 of the first sliding member 100.

[0074] Reference Figure 4 and Figure 5 As shown, in some embodiments, the auxiliary testing fixture provided in this application also includes a first connector 500, which connects the main body 410 and the slider portion 130 of the first slider 100.

[0075] In the above embodiment, the first connector 500 is used to install the main body 410 of the limiting member 400 onto the slider portion 130 of the first slider 100 to provide support.

[0076] The main body 410 of the first connector 500 and the limiting member 400, and the slider 130 of the first connector 500 and the first sliding member 100 can be detachably connected by threaded structure, snap-fit ​​structure, etc., to facilitate assembly and replacement.

[0077] For example, the first connector 500 can be a 6063-T5 aluminum profile.

[0078] Reference Figure 4 As shown, in some embodiments, at least one of the first slider 100 and the second slider 200 further includes a support portion 110 and at least one limiting portion 140. The slide rail portion 120 is disposed on the support portion 110, and the limiting portion 140 is disposed on the support portion 110 and located at at least one end of the slide rail portion 120. The limiting portion 140 is correspondingly disposed with the slider portion 130.

[0079] In the above embodiment, the support portion 110 can provide support to ensure the stability of the slide rail portion 120 during installation. Furthermore, a limiting portion 140 is provided on the support portion 110, located at the end of the slide rail portion 120. This limiting portion 140 can block the slider portion 130, preventing it from detaching from the end of the slide rail portion 120.

[0080] Specifically, refer to Figure 4 As shown, there can be two limiting parts 140, and the two limiting parts 140 are disposed at both ends of the extension direction of the slide rail part 120.

[0081] Furthermore, refer to Figure 2 and Figure 4As shown, the support portion 110 of the first slider 100 is used to be installed on the whole machine of the equipment, and the support portion 110 of the second slider 200 is disposed on the slider portion 130 of the first slider 100.

[0082] Reference Figure 1 and Figure 7 As shown, in some embodiments, there may be two first sliders 100, and the support portion 110 of the second slider 200 is disposed between the slider portions 130 of the two first sliders 100, so as to ensure the stability of the second slider 200 moving in the first direction.

[0083] Reference Figure 4 As shown, in some embodiments, at least one first connecting part 111 is provided on the support part 110 of the first sliding member 100, and the first connecting part 111 is used to connect with a second connecting part on the whole device.

[0084] In the above embodiment, the first sliding member 100 can be connected to the second connecting part on the whole equipment through the first connecting member 500 on the support part 110, so as to fix the first sliding member 100 on the whole equipment for convenient flatness measurement.

[0085] For example, the first connecting part 111 and the second connecting part can be a threaded structure, a snap-fit ​​structure, etc., to achieve the connection between the two.

[0086] Specifically, refer to Figure 4 As shown, the first connecting part 111 can be a fastening hole, and the second connecting part can be a threaded hole. The first connecting part 111 and the second connecting part are connected by a bolt passing through the fastening hole and the threaded hole.

[0087] It is understood that there is at least one first connecting part 111. The number of first connecting parts 111 can be one or more, as long as it corresponds to the number of second connecting parts on the whole device. This application embodiment does not impose too many restrictions on this.

[0088] Reference Figure 2 and Figure 3 As shown, in some embodiments, the mounting assembly 300 includes a mounting member 310 and a second connector 320, the second connector 320 connecting the mounting member 310 and the second slider 200.

[0089] Mounting member 310 has an extension direction, and the plane formed by the vertical and horizontal directions intersects the extension direction. Mounting member 310 is used to mount the measuring instrument and to adjust the distance between the measuring instrument and the part to be measured 10.

[0090] In the above embodiment, the mounting member 310 is used to mount the measuring instrument. The second connecting member 320 can be used to fix the mounting member 310 to the second sliding member 200 to improve the stability of the measuring instrument's movement.

[0091] Furthermore, the mounting component 310 extends along the extension direction, intersecting the plane formed by the vertical direction, horizontal direction, and extension direction. This allows the measuring instrument to adaptively adjust the distance between itself and the object to be measured 10 during installation. For objects of different sizes, a suitable installation position can be selected based on the height of the object to meet the flatness measurement requirements.

[0092] Reference Figure 2 and Figure 3 As shown, in some embodiments, the mounting element 310 is a cylinder.

[0093] In the above embodiment, the mounting component 310 is a cylindrical structure, with the height direction of the cylinder being the extension direction. The cylindrical structure facilitates clamping and fixing by the measuring instrument's built-in clamping structure, improving the stability of the measuring instrument's installation and preventing it from shaking during movement, which could affect the accuracy of the measurement.

[0094] Reference Figure 2 and Figure 3 As shown, in some specific embodiments, the side of the cylinder can be a smooth surface. A smooth surface can reduce the frictional resistance and obstruction when the clamping structure of the measuring instrument moves, so as to make it easier to adjust the distance between the measuring instrument and the workpiece 10 to be measured more smoothly.

[0095] In other specific embodiments, the side of the cylinder may be provided with limiting protrusions or mounting grooves to form multiple mounting positions. This can limit the clamping structure of the measuring instrument to the mounting position and prevent the measuring instrument from sliding along the axis of the cylinder during movement.

[0096] Reference Figure 2 and Figure 3 As shown, in some embodiments, the second connector 320 includes a mounting portion 321 and a first fastening portion 322. The mounting portion 321 is disposed on the second sliding member 200, the mounting member 310 abuts against the mounting portion 321, and the first fastening portion 322 connects the mounting member 310 and the mounting portion 321.

[0097] In the above embodiment, the mounting part 321 is disposed on the second sliding member 200, and the mounting part 321 supports the mounting member 310. The first fastening part 322 is used to connect the mounting member 310 and the mounting part 321 to realize the detachable connection between the two, so as to facilitate disassembly and maintenance.

[0098] For example, the first fastening part 322 can be a bolt, locking pin, buckle, or other structure.

[0099] Specifically, refer to Figure 2 and Figure 3 As shown, the first fastening part 322 is a bolt, the mounting part 321 has a through hole 3211, and the mounting part 310 has a threaded hole on the side facing the mounting part 321. The first fastening part 322 is threadedly connected to the threaded hole through the through hole 3211 to connect the mounting part 310 and the connecting part. This structure is simple and convenient for assembly.

[0100] Furthermore, refer to Figure 2 and Figure 3 As shown, the mounting part 321 is also provided with at least one mounting hole 3212, and at least one second fastening part 323 is inserted into the mounting hole 3212 and connected to the slider part 130 of the second slider 200 to fix the mounting part 321 onto the slider part 130 of the second slider 200, so as to facilitate the overall installation of the mounting assembly 300 onto the second slider 200.

[0101] For example, the second fastening part 323 can be a bolt.

[0102] Reference Figure 1 and Figure 7 As shown, the testing equipment provided in this application embodiment includes a measuring instrument (not shown in the figure) and any of the above auxiliary testing fixtures, with the measuring instrument mounted on the auxiliary testing fixture.
