Description

Technical Field

[0001] This utility model relates to the field of alloy frame technology, specifically to a reliability testing fixture for alloy frame shipments. Background Technology

[0002] Alloy frames are widely used in electronic devices, medical devices, and automotive parts due to their high strength, corrosion resistance, and aesthetic appeal. During the production of alloy frames, a series of reliability tests, such as strength tests and vibration tests, are required to ensure their quality and reliability before shipment. During strength testing, fixtures are required to fix the alloy frame in place to ensure the accuracy and safety of the test. However, existing alloy frame shipment reliability testing fixtures have the following shortcomings: First, they have poor adaptability to different specifications of alloy frames. A single fixture is often only suitable for one or a few specifications of alloy frames. When testing different specifications of alloy frames, different fixtures need to be changed, which is cumbersome and reduces testing efficiency. Second, during the testing process, the alloy frame is prone to positioning misalignment, affecting the accuracy of the test results. Therefore, developing a reliable shipping test fixture that can be applied to alloy frames of different specifications and has accurate positioning is of great practical significance. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a reliability test fixture for alloy frame shipments, which has the advantages of being applicable to alloy frames of different specifications and having accurate positioning.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reliability testing fixture for alloy frame shipments, comprising a test bench, a slide rail on the top of the test bench, movable frames slidably connected to both sides of the slide rail, support blocks fixedly connected to both sides of the bottom of the test bench, and a threaded rod with positive and negative threads rotatably connected between the two support blocks, the threaded rod with positive and negative threads being threadedly connected to the movable frames, a first servo motor fixedly connected to the left side of the left support block, the output end of the first servo motor being fixedly connected to the threaded rod with positive and negative threads, the top of the movable frame extending above the test bench, grooves provided on the front and back of the movable frame, movable columns slidably connected inside the grooves, a clamping block fixedly connected to the end of the movable column away from the movable frame, a fixed frame fixedly connected to the surface of the clamping block, teeth fixedly connected to the surface of the fixed frame, the number of teeth being several, and mounting slots provided on the sides of the left and right movable frames that are close to each other, a second servo motor fixedly connected inside the mounting slots, a gear fixedly connected to the output end of the second servo motor, the gear meshing with the teeth.

[0005] As a preferred embodiment of this invention, the top of the movable frame is provided with a sliding groove, and a clamping frame is slidably connected inside the sliding groove.

[0006] As a preferred embodiment of this utility model, a fixing block is fixedly connected to the top of the movable frame, and a first threaded rod is threadedly connected to the inside of the fixing block. An anti-slip pad is rotatably connected to the side of the first threaded rod near the movable frame. The anti-slip pad fits against the pressing frame, and a rotating handle is fixedly connected to the end of the first threaded rod away from the movable frame.

[0007] As a preferred embodiment of this utility model, the support block is internally fixedly connected to a bearing, with the outer ring of the bearing fixedly connected to the support block and the inner ring of the bearing fixedly connected to a threaded rod.

[0008] As a preferred embodiment of this invention, a protective frame is fixedly connected to the bottom of the test bench, and the number of protective frames is several, with the protective frames evenly distributed at the bottom of the test bench.

[0009] As a preferred embodiment of the present invention, a support frame is fixedly connected to the bottom of the test bench, and mounting blocks are fixedly connected to the front and rear sides of both sides of the support frame, with mounting openings on the surface of the mounting blocks.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model employs a first servo motor to drive the forward and reverse threaded rod to rotate, which can cause the two movable frames on both sides to move synchronously closer or further away within the slide rail, thereby adjusting the lateral spacing. Simultaneously, a second servo motor drives a gear to mesh with the teeth, enabling the movable column to move the clamping block back and forth within the groove, completing the longitudinal position adjustment. This bidirectional adjustment method allows the clamping block to precisely fit alloy frames of different sizes without the need to change the clamps, significantly improving the flexibility and efficiency of the test. Furthermore, the dual drive ensures the stability and reliability of the adjustment process, effectively avoiding test errors caused by incompatible specifications. This device has the advantages of being applicable to alloy frames of different specifications and providing accurate positioning.

[0011] 2. This utility model further enhances the fixing effect on the alloy frame by cooperating with the sliding groove at the top of the movable frame and the clamping frame. The clamping frame can move up and down along the sliding groove, and the clamping position can be adjusted according to the thickness of the alloy frame to ensure a tight fit against the frame surface. This design fills the longitudinal gap that may exist if the frame is fixed by clamps alone, preventing the frame from moving up and down due to force during the test, ensuring the stable posture of the frame during the test, and providing additional assurance for the accuracy of the test results. It is especially suitable for strength test scenarios that require the frame to withstand vertical forces. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 4As shown, a reliability testing fixture for alloy frame shipments includes a test bench 1. A slide rail 2 is provided on the top of the test bench 1. Movable frames 3 are slidably connected to both sides of the slide rail 2. Support blocks 8 are fixedly connected to both sides of the bottom of the test bench 1, and a threaded rod 9 with opposite threads is rotatably connected between the two support blocks 8. The threaded rod 9 is threadedly connected to the movable frame 3. A first servo motor 10 is fixedly connected to the left side of the left support block 8. The output end of the first servo motor 10 is fixedly connected to the threaded rod 9. The top of the movable frame 3 extends above the test bench 1. Grooves are provided on both the front and back of the movable frame 3, and movable columns 4 are slidably connected inside the grooves. A clamping block 5 is fixedly connected to the end of the movable column 4 away from the movable frame 3. A fixing frame 6 is fixedly connected to the surface of the clamping block 5, and teeth 7 are fixedly connected to the surface of the fixing frame 6. The number of teeth 7 is several. Mounting slots are provided on the sides of the two movable frames 3 that are close to each other, and a second servo motor 11 is fixedly connected inside the mounting slots. A gear 12 is fixedly connected to the output end of the second servo motor 11. Wheel 12 meshes with tooth 7. In actual use, the surface of the threaded rod 9 is provided with a retractable protective sleeve to prevent debris from falling into the thread groove on the surface of the threaded rod 9, thereby avoiding affecting the operation of the threaded rod 9. The surface of the fixing frame 6 and gear 12 can be provided with protective covers to prevent the operator from accidentally touching gear 12 or tooth 7 and getting injured. The protective cover and the retractable protective sleeve are common existing technologies, and will not be described in detail in this application. The relevant contents not disclosed in this application, such as the control circuit or power supply circuit of each electrical appliance in the device, are common knowledge to those skilled in the art, and will not be described in detail in this application. When using this device, this device is suitable for rectangular alloy frames. Adjust the clamping block 5 to fit the four corners of the inner wall of the rectangular alloy frame, thereby positioning the rectangular alloy frame. The clamping frame 13 prevents the rectangular alloy frame from moving up and down. By adjusting the rotation of the second servo motor 11, the gear 12 is rotated, thereby causing the fixing frame 6 on the surface of the front and rear clamping blocks 5 to move closer or further away from each other, thereby causing the front and rear clamping blocks 5 to move closer or further away from each other.

[0016] refer to Figure 3 The top of the movable frame 3 is provided with a sliding groove, and the inside of the sliding groove is slidably connected to the clamping frame 13.

[0017] As a technical optimization of this utility model, the cooperation between the sliding groove at the top of the movable frame 3 and the clamping frame 13 further enhances the fixing effect on the alloy frame. The clamping frame 13 can move up and down along the sliding groove, and the clamping position can be adjusted according to the thickness of the alloy frame to ensure a tight fit against the frame surface. This design fills the longitudinal gap that may exist if the clamping block 5 is used for fixing alone, preventing the frame from moving up and down due to force during the test, ensuring the stable posture of the frame during the test, and providing additional assurance for the accuracy of the test results. It is especially suitable for strength test scenarios that require the frame to withstand vertical forces.

[0018] refer to Figure 3 A fixing block 14 is fixedly connected to the top of the movable frame 3. A first threaded rod 15 is connected to the internal thread of the fixing block 14. An anti-slip pad is rotatably connected to the side of the first threaded rod 15 near the movable frame 3. The anti-slip pad is in contact with the clamping frame 13. A rotating handle is fixedly connected to the end of the first threaded rod 15 away from the movable frame 3.

[0019] As a technical optimization of this utility model, the fixing reliability of the clamping frame 13 is significantly improved by using the fixing block 14, the first threaded rod 15, the anti-slip pad, and the rotating handle structure. Rotating the rotating handle allows the first threaded rod 15 to advance within the fixing block 14, pushing the anti-slip pad to tightly squeeze the clamping frame 13. By increasing the friction, the clamping frame 13 is firmly locked in the required position, ensuring the continuous stability of the clamping state during the test.

[0020] refer to Figure 2 The support block 8 has a bearing fixedly connected inside, and the outer ring of the bearing is fixedly connected to the support block 8, while the inner ring of the bearing is fixedly connected to the threaded rod 9.

[0021] As a technical optimization of this utility model, the smoothness and stability of the rotation of the threaded rod 9 are effectively improved by setting the bearing inside the support block 8. The inner and outer rings of the bearing are fixed to the support block 8 and the threaded rod 9, respectively, converting the rotation of the threaded rod into rolling friction, which greatly reduces the frictional resistance during rotation, allowing the driving force of the first servo motor 10 to be transmitted more efficiently, and avoiding problems such as adjustment jamming or excessive motor load caused by excessive friction. At the same time, the bearing can play a precise radial positioning role for the threaded rod, preventing it from shifting or shaking during rotation, and ensuring the synchronicity and accuracy of the movement of the movable frames 3 on both sides.

[0022] refer to Figure 2 The bottom of the test bench 1 is fixedly connected to a protective frame 17. There are several protective frames 17, which are evenly distributed on the bottom of the test bench 1.

[0023] As a technical optimization of this utility model, the protective frame 17 at the bottom of the test bench 1 provides solid structural protection for the entire device. The protective frame 17 is evenly distributed at the bottom of the test bench 1 to prevent accidental contact by personnel and ensure the long-term stable operation of the test equipment.

[0024] refer to Figure 1 The bottom of the test bench 1 is fixedly connected to a support frame 16, and mounting blocks 18 are fixedly connected to the front and rear sides of both sides of the support frame 16. The surface of the mounting blocks 18 is provided with mounting openings.

[0025] As a technical optimization of this utility model, the support frame 16 and mounting block 18 structure facilitate the fixed installation and position adjustment of the device. The support frame 16 increases the overall height of the test bench 1, making it easier for operators to perform experimental operations and device maintenance, while also enhancing the structural stability of the test bench 1. The mounting openings on the surface of the mounting block 18 can be connected to the ground or other fixed bases to firmly fix the entire device and prevent positional displacement caused by equipment vibration during the test. This design allows the device to be stably placed on the laboratory floor and can also be flexibly installed on different test platforms according to experimental needs, thus expanding the applicability of the device.

[0026] The working principle and usage process of this utility model: When using this alloy frame shipment reliability test fixture, first ensure that all components of the device are in their initial state, check that there are no foreign objects on the surface of the test bench 1 and in the slide rail 2, that the movable frame 3 can slide smoothly in the slide rail 2, that there is no jamming of components such as the clamping block 5 and the movable column 4, and that all servo motors are properly connected and can operate normally. Place the alloy frame to be tested in a suitable position on the test bench 1, so that it is roughly in the center area of ​​the test bench 1, which facilitates subsequent positioning and fixing. Next, start the first servo motor 10. The first servo motor 10 drives the positive and negative threaded rod 9 to rotate between the two support blocks 8. Since the positive and negative threaded rod 9 is threadedly connected to the movable frame 3, the movable frames 3 on both sides will move away synchronously in the slide rail 2. Adjust the position of the movable frame 3 according to the lateral dimension of the alloy frame until the clamping block 5 on both sides of the movable frame 3 is close to the lateral edge of the inner wall of the alloy frame, and then turn off the first servo motor 10. Then restart the second servo motor 11. The output end of the second servo motor 11 drives the gear 12 to rotate. The gear 12 meshes with the teeth 7 on the surface of the fixed frame 6, so that the movable column 4 slides back and forth in the groove of the movable frame 3, thereby driving the clamping block 5 to move back and forth, so that the two clamping blocks 5 move away from each other. Adjust the front and rear positions of the clamping blocks 5 according to the longitudinal dimension of the alloy frame, so that the clamping blocks 5 accurately fit the four corners of the inner wall of the alloy frame, and complete the initial positioning of the alloy frame. Then turn off the second servo motor 11. Next, adjust the clamping frame 13 according to the thickness of the alloy frame, and push the clamping frame 13 downward along the sliding groove at the top of the movable frame 3 so that the bottom of the clamping frame 13 fits tightly against the upper surface of the alloy frame. Then, rotate the handle, and the handle drives the first threaded rod 15 to rotate and advance forward in the fixed block 14. The first threaded rod 15 pushes the anti-slip pad to squeeze the clamping frame 13. The friction between the anti-slip pad and the clamping frame 13 is used to firmly lock the clamping frame 13, ensuring that the clamping frame 13 applies appropriate pressure to the alloy frame, which can fix it firmly without damaging the frame.
