Description

Technical Field

[0001] This utility model relates to the field of tensile testing fixtures, specifically a tensile testing fixture for optical devices. Background Technology

[0002] The optical device tensile test is a test method used to evaluate the performance and reliability of optical devices when subjected to axial tensile force. It mainly simulates the tensile force that optical devices may encounter during actual installation, use and maintenance to observe whether the physical and optical properties of optical devices change, and whether their structure can withstand the corresponding tensile force without damage.

[0003] Tensile testing of optical devices is a key step in evaluating their performance and reliability. It usually requires the use of specialized tensile testing fixtures. A common type of tensile testing fixture for optical devices on the market consists of a fixed base, a fixture body, a tensile force application device, and a force measurement sensor. It can accurately test the tensile characteristics of optical devices, providing indispensable data support for quality control and product development, and effectively ensuring the scientific nature and accuracy of related work.

[0004] However, the current tensile testing fixture for optical devices has certain problems in practical use. When performing tensile testing on different models or types of optical devices, it is often necessary to adapt the fixture body accordingly. The installation of the fixture body mostly relies on bolt connections. This installation method is not only complicated but also time-consuming and labor-intensive, which seriously restricts the overall efficiency of the testing work. Therefore, further improvements are needed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a tensile testing fixture for optical devices to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensile testing fixture for optical devices, comprising a fixture body, a mounting block, and a fixing seat. A guide block is fixedly mounted on the outer wall of the end of the mounting block, and a guide groove and a limiting groove are formed on the outer wall of the guide block. A limiting post is fixedly mounted on the outer wall of the top of the fixing seat. A bidirectional threaded rod is rotatably mounted inside the fixing seat, and a handle is fixedly mounted on the end of the bidirectional threaded rod. A limiting block is threadedly connected to the outer wall of the bidirectional threaded rod, and a clamping block is fixedly mounted on the top of the limiting block. A locking block is fixedly mounted on the outer wall of the clamping block, and a slider is fixedly mounted on the outer wall of the limiting block. A locking groove corresponding to the locking block is formed on the outer wall of the mounting block.

[0007] By adopting the above technical solution, the coordinated operation of the limiting post, guide groove, and limiting groove effectively avoids the problem of angle deviation during the installation of the fixture body, achieving precise and convenient angle limitation, improving the accuracy and stability of installation. The rotation of the bidirectional threaded rod drives the limiting block and clamping plate to slide, which, together with the stable movement of the slider in the fixed seat, makes the clamping plate outer wall block and the mounting block outer wall slot tightly fit together, achieving convenient and stable installation of the fixture body. During disassembly, the clamping plate can be easily released from the mounting block by reversing the rotation handle, and the fixture body can be removed. The operation is simple and quick, greatly improving installation efficiency and reducing installation time and labor costs.

[0008] Furthermore, multiple sets of limiting posts are provided at equal angles on the top outer wall of the fixed base, and the top corners of the limiting posts are designed at bevels.

[0009] By adopting the above technical solution, the installation angle of the fixture body is limited by the limiting post.

[0010] Furthermore, the guide block is designed in a circular shape, and the thickness of the guide block is greater than the length of the limiting post.

[0011] By adopting the above technical solution, the angle of the fixture body can be conveniently limited by the guide plate.

[0012] Furthermore, the width of the guide groove corresponds to the outer diameter of the limiting post, and the top of the guide groove is designed with an arc-shaped sloping surface. Multiple sets of guide grooves and limiting grooves are provided corresponding to the limiting post.

[0013] By adopting the above technical solution, the clamp body can be inserted into the fixed seat at the same time, and the limiting post can be quickly and conveniently entered into the limiting groove through the guide groove to limit the angle of the clamp body.

[0014] Furthermore, two sets of clamping blocks are symmetrically arranged on both sides of the mounting block, and the side of the clamping block closest to the mounting block is designed in an arc shape corresponding to the outer wall of the mounting block.

[0015] By adopting the above technical solution, the clamping block and the mounting block are tightly fitted together, achieving a stable installation.

[0016] Furthermore, the cross-section of the card block is fan-shaped, and the corner of the card block close to the mounting block is angled. Multiple sets of card blocks are evenly spaced on the outer wall of the clamping block.

[0017] By adopting the above technical solution, the card block and the card slot cooperate with each other, and the main body of the clamp is conveniently and stably installed by the drive of the bidirectional threaded rod.

[0018] Furthermore, the slider has a dovetail design, and the slider is symmetrically arranged on both sides of the outer wall of the limiting block.

[0019] By adopting the above technical solution, the sliding of the limiting block and the clamping plate inside the fixed seat becomes more stable.

[0020] In summary, the present invention has the following main advantages:

[0021] This utility model, by incorporating a slot, a limiting post, a guide block, a guide groove, a limiting groove, a bidirectional threaded rod, a handle, a clamping block, a limiting block, a locking block, and a slider, enables the limiting post to work in tandem with the guide groove and limiting groove. This effectively avoids angular deviations during fixture installation, achieving precise and convenient angle limitation, thus improving installation accuracy and stability. The rotation of the bidirectional threaded rod drives the limiting block and clamping plate to slide, which, combined with the stable movement of the slider within the fixed seat, ensures a tight fit between the locking block on the outer wall of the clamping plate and the locking groove on the outer wall of the mounting block. This achieves convenient and stable installation of the fixture body. During disassembly, simply reverse the operation of the handle to easily release the clamping plate from the mounting block and remove the fixture body. The operation is simple and quick, greatly improving installation efficiency and reducing installation time and labor costs. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] A tensile testing fixture for optical devices, such as Figure 1 - Figure 7 As shown, the fixture includes a main body 1, a mounting block 2, and a fixed base 3. A guide block 4 is fixedly installed on the outer wall of the end of the mounting block 2, and the outer wall of the guide block 4 has a guide groove 41 and a limiting groove 42. A limiting post 31 is fixedly installed on the top outer wall of the fixed base 3. The coordinated operation of the limiting post 31 with the guide groove 41 and the limiting groove 42 effectively avoids the problem of angle deviation during the installation of the fixture main body 1, achieves precise and convenient angle limitation, and improves the accuracy and stability of the installation. A bidirectional threaded rod 5 is rotatably installed inside the fixed base 3, and a handle 51 is fixedly installed at the end of the bidirectional threaded rod 5. A limiting block 61 is threadedly connected to the outer wall of the bidirectional threaded rod 5, and the top of the limiting block 61 is... A clamping block 6 is fixedly installed, and a locking block 62 is fixedly installed on the outer wall of the clamping block 6. A slider 63 is fixedly installed on the outer wall of the limiting block 61. The outer wall of the mounting block 2 has a slot 21 corresponding to the locking block 62. The rotation of the bidirectional threaded rod 5 drives the limiting block 61 and the clamping plate to slide. With the stable movement of the slider 63 in the fixed seat 3, the locking block 62 on the outer wall of the clamping plate and the slot 21 on the outer wall of the mounting block 2 are tightly fitted, achieving convenient and stable installation of the clamping body 1. When disassembling, the clamping plate can be easily released from the mounting block 2 and the clamping body 1 can be taken out by reversing the operation of the handle 51. The operation is simple and quick, which greatly improves the installation efficiency and reduces the installation time and labor costs.

[0033] Please see Figure 2 and Figure 3 Multiple sets of limiting posts 31 are provided at equal angles on the top outer wall of the fixed base 3, and the top corners of the limiting posts 31 are designed with bevels, so that the installation angle of the fixture body 1 is limited by the limiting posts 31.

[0034] Please see Figure 1 - Figure 6 The guide block 4 has an overall circular design, and the thickness of the guide block 4 is greater than the length of the limiting post 31, which makes it easy to limit the angle of the fixture body 1 through the guide plate.

[0035] Please see Figure 2 - Figure 6The width of the guide groove 41 corresponds to the outer diameter of the limiting post 31, and the top of the guide groove 41 is designed with an arc-shaped sloping surface. Both the guide groove 41 and the limiting groove 42 are provided with multiple sets corresponding to the limiting post 31, so that when the fixture body 1 is inserted into the fixing seat 3, the limiting post 31 can quickly and conveniently enter the limiting groove 42 through the guide groove 41 to limit the angle of the fixture body 1.

[0036] Please see Figure 2 - Figure 4 Two sets of clamping blocks 6 are symmetrically arranged on both sides of the mounting block 2, and the side of the clamping block 6 close to the mounting block 2 is designed with an arc shape corresponding to the outer wall of the mounting block 2, so that the clamping block 6 fits tightly with the mounting block 2 and achieves stable installation.

[0037] Please see Figure 2 - Figure 4 The cross-section of the clamping block 62 is fan-shaped, and the corner of the clamping block 62 close to the mounting block 2 is angled. Multiple sets of clamping blocks 62 are evenly spaced on the outer wall of the clamping block 6, so that the clamping block 62 and the slot 21 cooperate with each other and achieve convenient and stable installation of the clamping body 1 by driving the bidirectional threaded rod 5.

[0038] Please see Figure 2 - Figure 4 The slider 63 has a dovetail design and is symmetrically arranged on both sides of the outer wall of the limiting block 61, which makes the sliding of the limiting block 61 and the clamp plate inside the fixed seat 3 more stable.

[0039] The working principle of this utility model is as follows: When installing the fixture body 1, align the mounting block 2 with the mounting groove on the outer wall of the fixed seat 3 and insert it into the fixed seat 3 until the bottom of the limiting block 61 is in contact with the top of the limiting post 31. Continue to insert the mounting block 2 so that the limiting post 31 slides into the limiting groove 42 along the inclined surface of the guide groove 41, thereby conveniently limiting the angle of the fixture body 1. Then, manually turn the handle 51 to drive the bidirectional threaded rod 5 to rotate, causing the two sets of limiting blocks 61 and the clamping plate to slide towards the mounting block 2 at the same time. At this time, the slider 63 slides inside the fixed seat 3 to ensure the stable sliding of the clamping plate until the clamping block 62 on the outer wall of the clamping plate is tightly in contact with the clamping groove 21 on the outer wall of the mounting block 2, thus completing the convenient and stable installation of the fixture body 1.

[0040] When disassembling the fixture body 1, first manually turn the handle 51 in the opposite direction to rotate the bidirectional threaded rod 5, allowing the limit block 61 and the clamping block 6 to slide away from the mounting block 2 until the locking block 62 completely slides out of the slot 21, releasing the restriction on the fixture body 1. Then manually remove the fixture body 1 to complete the disassembly operation.
