Description

Technical Field

[0001] This utility model relates to the field of test fixtures and jigs, specifically a quick-release vibration test fixture and jig. Background Technology

[0002] Vibration testing is used to evaluate the vibration resistance of equipment in its intended transportation and use environment. Its purpose is to discover defects in product design, process, and manufacturing, to fully understand the product's stress response characteristics and weak points, and to determine whether the product is qualified. Fixtures are a key component of vibration testing fixtures. The main function of fixtures is to securely fix the test object on the vibration testing fixture.

[0003] To maintain the stability of test samples, most vibration testing fixtures on the market are equipped with multi-directional clamps to hold the test samples securely and prevent them from falling off during vibration testing. Different test samples typically require different clamps, necessitating the selection of appropriate clamps for each sample. Furthermore, the connections between the clamps and the vibration test fixtures on most vibration testing fixtures are independent and fixed. Therefore, changing the clamps requires individually operating the connecting tools on each clamp, which is inconvenient for quick replacement and installation, thus affecting testing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-release vibration testing fixture to solve the problem mentioned in the background art that current vibration testing fixtures on the market require individual operation of the independent connecting tools on each fixture.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release vibration test fixture, including an operating table and a clamp, the clamp being located at the top of the operating table, an installation rod being slidably connected to the operating table, the clamp being inserted into one end of the installation rod facing the center of the operating table, a limit rod being slidably connected to the installation rod, a second rotating ring being located below the limit rod, the up and down movement of the second rotating ring being used to install the clamp and the installation rod through the limit rod, and a base being fixed on the support foot.

[0006] Preferably, a servo motor is installed at the bottom of the base, a connecting block is installed at the output end of the servo motor, a connecting ball is wrapped inside the connecting block, and an operating table is installed at the top of the connecting ball.

[0007] Preferably, the diameter of the connecting ball is the same as the inner diameter of the connecting block, and the top of the connecting ball protrudes beyond the top of the connecting block.

[0008] Preferably, a first fixing ring and a second fixing ring are installed on the top of the operating table. The inner sides of the first fixing ring and the second fixing ring are respectively threaded with a first rotating ring and a second rotating ring. Multiple mounting blocks are evenly installed on the inner side of the first rotating ring.

[0009] Preferably, the mounting block and the mounting rod correspond one-to-one, both sides of the mounting block are inclined, the lifting height of the mounting block is less than the distance from the bottom of the mounting block to the top of the mounting rod, and a through hole is opened at the position where the clamp and the mounting rod overlap.

[0010] Preferably, the limiting rod is configured with an "L" shape, with the bottom end of the limiting rod in the horizontal position contacting the top end of the rotating ring, and the limiting rod in the vertical position penetrating into the through hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The clamp is inserted into the mounting rod, and the vertical position of the limiting rod is aligned with the through hole. The two rotating rings rotate in the forward direction, pushing multiple limiting rods upward simultaneously, so that the vertical part of the limiting rod is inserted into the through hole, thus fixing the clamp and the mounting rod. Reverse rotation does not cause the limiting rods to collide. The limiting rods separate from the through hole by their own weight, which can be quickly disassembled, making it easy to replace the clamp quickly, reducing operation steps, and greatly improving work efficiency. At the same time, the position of the clamp can be adjusted according to the vibration test sample, making it suitable for various types of vibration test samples, thus broadening the overall application range.

[0018] 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.

[0019] Please see Figures 1-4 The present invention provides the following technical solution:

[0020] A quick-release vibration testing fixture includes an operating platform 8 and a clamp 9. The clamp 9 is located on the top of the operating platform 8. An installation rod 10 is slidably connected to the operating platform 8. The clamp 9 is inserted into one end of the installation rod 10 facing the center of the operating platform 8. A first fixing ring 11 and a second fixing ring 17 are installed at the top of the operating platform 8. A first rotating ring 12 and a second rotating ring 16 are threadedly connected to the inner sides of the first fixing ring 11 and the second fixing ring 17, respectively. A plurality of installation blocks 13 are evenly installed on the inner side of the first rotating ring 12. Each installation block 13 corresponds to one of the installation rods 10. Both sides of the installation blocks 13 are inclined. The lifting height of the installation blocks 13 is less than the distance from the bottom of the installation block 13 to the top of the installation rod 10.

[0021] Hold the test object to be vibrated in the center and rotate the rotating ring 12 by hand. As the rotating ring 12 rotates, it synchronously drives the mounting block 13 to rotate. Because the rotating ring 12 is threadedly connected to the fixed ring 11, the rotating ring 12 rises and falls synchronously during rotation. Since the mounting block 13 has an inclined structure on both sides, it gradually moves closer to the mounting rod 10 during rotation. When the mounting block 13 rotates to contact the mounting rod 10, the side of the mounting block 13 pushes the mounting rod 10, and the mounting rod 10 drives the clamp 9 synchronously. Move the clamp 9 closer to the test item, gradually clamping it. When the rotating ring 12 can no longer rotate, the clamp 9 has stably clamped the test item. Then, you can release your hand from the test item to fix it in place. When you need to release the test item, rotate the rotating ring 12 in the opposite direction. The rotating ring 12 rotates in the opposite direction, causing the mounting block 13 to gradually separate. When the mounting block 13 separates from the mounting rod 10, push the mounting rod 10 outward by hand until the mounting rod 10 separates from the test sample. Then you can take out the test sample after the test.

[0022] A limiting rod 15 is slidably connected to the mounting rod 10. The second rotating ring 16 is located below the limiting rod 15. The up and down movement of the second rotating ring 16 enables the clamp 9 to be installed with the mounting rod 10 through the limiting rod 15. The limiting rod 15 is set with an "L" structure. The bottom end of the limiting rod 15 in the horizontal position contacts the top end of the second rotating ring 16. The limiting rod 15 in the vertical position penetrates into the through hole 14.

[0023] This device allows for the replacement of the chuck 9 according to the test sample. Rotating the second rotating ring 16 clockwise by hand causes it to move downwards synchronously, gradually separating from the limiting rod 15 until the vertical position of the limiting rod 15 separates from the through hole 14. Then, the chuck 9 is pulled out, achieving rapid disassembly and improving work efficiency. The new chuck 9 is then inserted into the mounting rod 10. Because the mounting rod 10 supports the chuck 9, the through hole 14 on the chuck 9 and the mounting rod 10... The through hole 14 is located on the same vertical plane. Then, the rotating ring 16 is rotated in the opposite direction and rises synchronously. When the rotating ring 16 rises to contact the limiting rod 15, the top of the rotating ring 16 pushes the limiting rod 15. The limiting rod 15 is inserted vertically into the through hole 14 until the rotating ring 16 can no longer rotate in the opposite direction. At this time, the top of the vertical position of the limiting rod 15 has protruded outside the through hole 14. The limiting rod 15 limits the clamp 9 and the mounting rod 10, thereby installing the clamp 9.

[0024] A base 3 is fixed on the supporting foot 1. A through hole 14 is opened at the position where the clamp 9 overlaps with the mounting rod 10. A servo motor 2 is installed at the bottom of the base 3. A connecting block 6 is installed at the output end of the servo motor 2. A connecting ball 7 is wrapped inside the connecting block 6. An operating table 8 is installed at the top of the connecting ball 7. The diameter of the connecting ball 7 is the same as the inner diameter of the connecting block 6. The top of the connecting ball 7 protrudes from the top of the connecting block 6. Magnetic block 1 4 and magnetic block 2 5 have the same magnetic poles and repel each other.

[0025] After the test sample is clamped, the servo motor 2 is started, which causes the connecting block 6 to rotate. The connecting block 6 drives the connecting ball 7 to rotate synchronously, and the connecting ball 7 in turn drives the operating table 8 to move. When the second magnetic block 5 under the operating table 8 rotates synchronously, and the second magnetic block 5 rotates above the first magnetic block 4, since the magnetic poles of the first magnetic block 4 and the second magnetic block 5 are the same, the repulsive force between the connecting block 6 and the connecting ball 7 causes the operating table 8 to rotate to the side. When the second magnetic block 5, which is in an inclined state, rotates to the top of the first magnetic block 4, the first magnetic block 4 will again cause the operating table 8 to rotate to the side, thereby causing the operating table 8 to swing and vibrate.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
