Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a hanging force detection device. Background Technology

[0002] For enclosure-type products, such as monitor enclosures, the C-shaped cross-sectional shape of the enclosure is cleverly utilized during the processing and assembly process to hang the enclosure on the corresponding mounting fixture.

[0003] In practical use, the mounting force of existing enclosure products on tooling is often difficult to accurately know and measure. However, if the mounting force is too small, the product is prone to detachment or shaking, resulting in defects. If the mounting force is too large, the product may also be damaged due to the stress during mounting. Therefore, in order to ensure the product yield rate, it is necessary to be able to accurately measure the magnitude of the force applied to the product during mounting. Utility Model Content

[0004] To address the aforementioned issues, this application provides a reasonably structured mounting force detection device. This device uses a detection fixture to simulate the state of a product mounted on a mounting tool, thereby detecting the magnitude of the mounting force. This effectively ensures the proper mounting of the product. The device is simple, convenient, and highly practical.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A mounting force testing device includes a mounting fixture as the object to be tested and a testing jig for testing the mounting force of the mounting fixture;

[0007] The mounting fixture includes an upper support and a lower support arranged opposite to each other. The upper and lower supports together fix the product by forces that move away from each other.

[0008] The testing fixture includes a vertically arranged support frame, a force sensor mounted on the top of the support frame via a support, and an upper force-bearing component mounted on the downward-facing output end of the force sensor; a lower force-bearing component is mounted below the support frame.

[0009] The upper force-bearing component abuts above the upper support component, and the lower force-bearing component abuts below the lower support component.

[0010] As a further improvement to the above technical solution:

[0011] It also includes a power control unit. The force sensor is electrically connected to the power control unit, and the value fed back by the force sensor is displayed on the display screen of the power control unit.

[0012] It also includes a ranging element, which measures the distance from the upward-facing force-bearing component.

[0013] The upper force-bearing component has a "Z"-shaped structure. Of the two parallel arms of the upper force-bearing component, one arm is horizontally connected to the force sensor output section, and the other arm is horizontally located directly above the ranging element.

[0014] When the upper and lower force-bearing components are located on the same straight line, the ranging element is installed on the side of the lower force-bearing component; the lower force-bearing component has a "Z" shaped structure, and of the two parallel arms of the lower force-bearing component, one arm is vertically attached to the side of the support frame, and the ranging element is installed on the outer side of the other arm.

[0015] When the upper and lower force-bearing components are staggered in the vertical direction, the ranging element is installed at intervals directly below the upper force-bearing component via the lower connecting component, and the lower connecting component is installed on the side of the support frame.

[0016] The structure of the support frame is as follows: it includes vertical beams arranged at intervals on the left and right, multiple horizontal beams installed at intervals between the two vertical beams, a support installed on the side of the uppermost horizontal beam, and a lower load-bearing component installed on the side of the lowermost horizontal beam.

[0017] The mounting fixture is supported by multiple sets of corresponding upper and lower mounting components. Each set of upper and lower mounting components has multiple upper and lower rods spaced apart along the length of their respective support rods. The upper support is installed with the top surface of the upper rod facing upwards, and the lower support is installed with the bottom surface of the lower rod facing downwards. The corresponding upper and lower rods are used to mount the product together through the upper and lower support components.

[0018] The top surface of the upper rod is equipped with one or two upper support members as needed, and the bottom surface of the lower rod is equipped with one or two lower support members as needed; the upper force-bearing members are arranged corresponding to the upper support members, and the lower force-bearing members are arranged corresponding to the lower support members.

[0019] Both the upper and lower support members are L-shaped structures, with their vertical parts facing upwards and downwards respectively, and the upper and lower support members are connected by gravity and / or elastic force, forming a force that causes them to move in opposite directions.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention uses a testing fixture where the upper force-bearing component abuts against the upper support component and the lower force-bearing component abuts against the lower support component. This allows the testing fixture to simulate the state of a product being mounted on a mounting fixture, thereby detecting the magnitude of the mounting force. This effectively ensures the proper mounting of the product and helps guarantee its stable and reliable mounting. The overall operation is simple, convenient, and highly practical.

[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0033] like Figure 1 As shown, a mounting force detection device in this embodiment includes a mounting fixture 1 as the object of detection and a detection jig 2 for detecting the mounting force of the mounting fixture 1.

[0034] like Figure 2 and Figure 3 As shown, the mounting fixture 1 includes an upper support 111 and a lower support 121 arranged opposite to each other. The upper support 111 and the lower support 121 work together to hang and fix the product 10 by forces that move away from each other. Figure 6 As shown;

[0035] The testing fixture 2 includes a vertically arranged support frame. A force sensor 28 is mounted on the top of the support frame via a support 29. An upper force-bearing component 21 is mounted on the downward-facing output end of the force sensor 28. Figure 5 As shown; a lower load-bearing component 22 is installed below the support frame;

[0036] The upper force-bearing component 21 abuts against the upper support component 111 above, and the lower force-bearing component 22 abuts against the lower support component 121 below.

[0037] In practical use, the testing fixture 2 is mounted on the mounting fixture 1, with the upper force-bearing component 21 abutting above the upper support component 111 and the lower force-bearing component 22 abutting below the lower support component 121, simulating the scenario of the product 10 being mounted on the mounting fixture 1. The mounting fixture 1 stably mounts and fixes the testing fixture 2, thus simulating the state of the product 10 being mounted on the mounting fixture 1. At this time, the upper force-bearing component 21 will feed back the force to the force sensor 28, thereby enabling convenient and rapid acquisition of the mounting force.

[0038] Of course, in actual operation, the interval between the upper force-bearing component 21 and the lower force-bearing component 22 is set to be consistent with the distance between the upper and lower hanging openings of the product 10, so as to effectively ensure the simulation of the hanging of the product 10 by the detection fixture 2 is real and accurate.

[0039] It also includes a power control unit 3. The force sensor 28 is electrically connected to the power control unit 3. The value fed back by the force sensor 28 is displayed on the display screen 30 on the power control unit 3 to realize the visualization of the detection.

[0040] like Figure 4 As shown, it also includes a ranging element 23, which measures the distance toward the upper force-bearing member 21, thereby enabling the detection of distance changes of the upper force-bearing member 21 while realizing force detection.

[0041] like Figure 2 and Figure 5 As shown, the upper force-bearing component 21 has a "Z" shaped structure. Of the two parallel arms of the upper force-bearing component 21, one arm is horizontally connected to the output of the force sensor 28, and the other arm is horizontally located directly above the ranging element 23, so that distance detection can be achieved while the upper force-bearing component 21 is subjected to force.

[0042] In actual operation, the arrangement of the upper support 111 and lower support 121 on the mounting fixture 1 needs to be matched with the actual product 10. When the model or size of the product 10 changes, the positions of the upper support 111 and lower support 121 may need to be adjusted appropriately.

[0043] In one embodiment, such as Figure 1 As shown, when the upper force-bearing component 21 and the lower force-bearing component 22 are located on the same straight line, the ranging element 23 is installed on the side of the lower force-bearing component 22; as Figure 3 and Figure 4As shown, the lower force-bearing component 22 has a "Z" shaped structure. Of the two parallel arms of the lower force-bearing component 22, one arm is vertically attached to the side of the support frame, and the other arm has a ranging element 23 installed on its outer side.

[0044] In another embodiment, when the upper force-bearing member 21 and the lower force-bearing member 22 are staggered in the vertical direction, the ranging element 23 is installed at intervals directly below the upper force-bearing member 21 via the lower connecting member 26, and the lower connecting member 26 is installed on the side of the support frame.

[0045] exist Figure 4 In the embodiment shown, the structure of the support frame is as follows: it includes vertical beams 25 arranged at intervals on the left and right, multiple horizontal beams 24 are installed at intervals between the two vertical beams 25, a support 29 is installed on the side of the uppermost horizontal beam 24, and a lower load-bearing member 22 is installed on the side of the lowermost horizontal beam 24.

[0046] In this embodiment, a transverse elongated hole 241 can be opened on the crossbeam 24. The support 29 and the lower load-bearing member 22 are installed on the crossbeam 24 by combining the transverse elongated hole 241 with external fasteners. In actual use, the installation position of the support 29 and the lower load-bearing member 22 on the crossbeam 24 can be easily adjusted according to actual usage requirements via the transverse elongated hole 241.

[0047] Of course, in actual use, the support 29 and the lower load-bearing component 22 can also be installed on other suitable crossbeams 24 according to actual testing and usage requirements, so as to simulate different usage scenarios for products 10 with different opening sizes.

[0048] In this embodiment, according to actual needs, a lower connecting member 26 can be installed on the crossbeam 24 and a side connecting member 27 can be installed on the vertical beam 25 to realize the installation of the detection fixture 2 on external operating parts such as the robot or other structural parts, without affecting the contact between the upper force-bearing member 21 and the lower force-bearing member 22 on the hanging fixture 1 relative to the upper support member 111 and the lower support member 121.

[0049] like Figure 1 and Figure 6 As shown, the mounting fixture 1 is supported by multiple sets of upper mounting components 11 and lower mounting components 12 corresponding to each other. Each set of upper mounting components 11 and lower mounting components 12 has multiple upper rods 112 and lower rods 122 spaced apart along the length of their respective support rods. The upper support member 111 is installed with the top surface of the upper rod 112 facing upward, and the lower support member 121 is installed with the bottom surface of the lower rod 122 facing downward. The upper rods 112 and lower rods 122 corresponding to each other are used to mount the product 10 through the upper support member 111 and the lower support member 121, so that multiple products 10 can be mounted simultaneously through a single mounting fixture 1.

[0050] The top surface of the upper rod 112 is equipped with one or two upper support members 111 as required, and the bottom surface of the lower rod 122 is equipped with one or two lower support members 121 as required; the upper force-bearing member 21 is arranged in correspondence with the upper support member 111, and the lower force-bearing member 22 is arranged in correspondence with the lower support member 121.

[0051] Both the upper support member 111 and the lower support member 121 are L-shaped structures. The vertical parts of the upper support member 111 and the lower support member 121 are arranged opposite to each other, facing upward and downward respectively. The upper support member 111 and the lower support member 121 are subjected to forces that cause them to move in opposite directions through gravity and / or elastic force.

[0052] exist Figure 1 In the illustrated embodiment, among the upper hanging assembly 11 and lower hanging assembly 12 arranged in groups above, the upper hanging assembly 11 is fixedly arranged relative to the frame of the hanging fixture 1, while the lower hanging assembly 12 is arranged to move up and down relative to the frame of the hanging fixture 1. When hanging the product 10, the lower hanging assembly 12 moves upward relative to the frame, so that the distance between the upper support member 111 and the lower support member 121 is less than the distance between the upper and lower openings of the product 10. Then, the lower hanging assembly 12 is released, thereby fixing the product 10 in place. At this time, the weight of the lower hanging assembly 12 will be applied to the product 10 through the lower support member 121. When a spring is installed between the lower hanging assembly 12 and the frame, the deformation force of the spring will also be applied to the product 10 through the lower support member 121.

[0053] exist Figure 1 In the embodiment shown, among the upper hanging assembly 11 and lower hanging assembly 12 arranged in groups below, the lower hanging assembly 12 is fixedly arranged relative to the frame of the hanging fixture 1, while the upper hanging assembly 11 is arranged to move up and down relative to the frame of the hanging fixture 1. At this time, by installing a spring between the upper hanging assembly 11 and the frame, the hanging force is applied to the product 10 through the elastic deformation force of the spring via the upper hanging assembly 11.

[0054] In practical use, the springs can be replaced or changed to adjust and match the product's mounting force requirements.

[0055] After the spring is adjusted or replaced, or after the product 10 is replaced, the mounting force of the mounting fixture 1 can be tested in a timely, convenient and fast manner through the testing fixture 2, so as to meet the mounting use of the product 10.

[0056] This utility model uses a testing fixture to simulate the state of a product being mounted on a mounting fixture, thereby detecting the magnitude of the mounting force and effectively ensuring the proper mounting of the product. It helps to ensure the stable and reliable mounting of the product. The overall operation is simple, convenient, and practical.
