Technical Field

[0001] This utility model relates to the field of vibration table clamping technology, and in particular to a quick-release clamp for an electric vibration table. Background Technology

[0002] In the application of electric vibration tables, vibration resistance testing of various products is crucial, as it helps evaluate the performance and reliability of products under different vibration environments. Publication No. CN202133525U discloses a universal fixture for a three-dimensional vibration table, consisting of a mother fixture and daughter fixtures. The mother fixture has a cubic structure, with one side connected to the moving coil of the vibration table via a first set of screws. Daughter fixture fixing devices are respectively provided on the three mutually perpendicular faces of the mother fixture. The three daughter fixtures are rigidly connected to the mother fixture via a second set of screws. Each daughter fixture also has one or more sets of studs with adjustable column height. This universal fixture, through the rigid connection of the moving coil of the vibration table, the mother fixture, and the daughter fixtures, can conveniently realize vibration resistance testing of the sample in three axes. It features a simple structure, convenient operation, and effectively improves testing efficiency.

[0003] However, in practical use, the above-mentioned technical solution has obvious shortcomings. This general-purpose fixture is not convenient to operate when clamping workpieces. Its rigid connection and fixation via screw sets requires repeated screw tightening when installing and removing workpieces of different shapes and sizes, a cumbersome and time-consuming process. Especially during batch testing, frequent screw operations significantly reduce work efficiency and increase testing time costs. Furthermore, this clamping method may cause surface damage to irregularly shaped or easily damaged workpieces during clamping, affecting the accuracy of test results. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release clamp for an electric vibration table. By pulling a sliding rod, a drive block is activated, which in turn moves a connecting block via a pull rope, causing the two sliding clamps to separate. After placing the workpiece, the sliding rod is released, and the spring force pushes the abutment pad on the side of the sliding clamp to conveniently clamp the workpiece. The process is simple and fast, greatly saving time and improving batch testing efficiency. The abutment pad is soft and elastic, which can avoid damage to the workpiece during clamping, ensuring the integrity of the workpiece before testing and improving the accuracy of test results. Furthermore, the stable clamping reduces test interruptions and data errors, further reducing costs and improving overall testing efficiency.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0016] 1. This utility model realizes a quick-release clamp for an electric vibration table. By pulling the sliding rod, the drive block is driven, and then the connecting block is moved by the pull rope, which separates the two sliding clamps. After the workpiece is placed, the sliding rod is released, and the elastic force of the spring pushes the abutment pad on the side of the sliding clamp to conveniently clamp the workpiece. The process is simple and fast, which greatly saves time and improves the efficiency of batch testing. The abutment pad is soft and elastic, which can avoid damage to the workpiece during clamping, ensure the integrity of the workpiece before testing, and improve the accuracy of test results. Moreover, the stable clamping reduces test interruption and data error, further reducing costs and improving overall testing efficiency.

[0017] 2. Convenient Clamping: This invention features a unique structural design. The operator first pulls the sliding lever, which moves the drive block. The drive block then pulls the connecting block via a rope, separating the two sliding clamping plates. The workpiece is then placed on the placement plate on the inner wall of the placement frame, and the sliding lever is released. Under the elastic force of the abutment spring, the abutment pads on the sides of the sliding clamping plates conveniently clamp the workpiece from the side. The entire process is simple and quick, eliminating the need for repeated screw tightening as in existing technologies, significantly saving workpiece clamping time and improving work efficiency, making it particularly suitable for batch testing scenarios.

[0018] 3. Wide range of applications: The clamping method of this quick-release fixture does not depend on the specific size of the workpiece and can adapt to the clamping needs of a variety of different types of workpieces.

[0019] 4. Workpiece Protection: The workpiece is clamped from the side using abutment pads. These pads are typically made of soft and elastic materials, effectively preventing damage to the workpiece surface during clamping. This is especially important for workpieces with high surface precision requirements or those that are easily damaged, ensuring the integrity of the workpiece before testing and thus improving the accuracy and reliability of the test results.

[0020] 5. Improved testing efficiency: The convenient and quick clamping process reduces the time spent on workpiece installation and removal, allowing the vibration table to perform tests more frequently. At the same time, the stable clamping method reduces test interruptions or inaccurate data caused by unstable clamping, further improving overall testing efficiency and reducing testing costs.

[0031] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] Please refer to Figures 1 to 3 As shown, an embodiment of the present invention provides a quick-release clamp for an electric vibration table, comprising: a vibration table body 1, and a clamping assembly 3 for clamping and fixing a workpiece body 2 is installed on the top of the vibration table body 1.

[0033] The clamping assembly 3 includes a placement frame 301 fixedly connected to the top of the vibration table body 1. A placement plate 3011 for placing the workpiece body 2 is fixedly connected to the inner wall of the placement frame 301. Two clamping structures 3012 for clamping and positioning the workpiece body 2 are installed on the placement plate 3011.

[0034] By adopting the above technical solution, pulling the sliding rod 3041 drives the drive block 3042, and then the connecting block 3022 moves via the pull rope 3043, causing the two sliding clamps 3021 to separate. After placing the workpiece, the sliding rod 3041 is released, and the elastic force of the spring 303 pushes the abutment pad 3031 on the side of the sliding clamp 3021 to conveniently clamp the workpiece. The process is simple and fast, greatly saving time and improving the efficiency of batch testing. The abutment pad 3031 is soft and elastic, which can avoid damage to the workpiece during clamping, ensuring the integrity of the workpiece before testing and improving the accuracy of test results. Moreover, the stable clamping reduces test interruptions and data errors, further reducing costs and improving overall testing efficiency.

[0035] To achieve flexible sliding and precise positioning of the sliding clamp 3021 on the placement plate 3011, in this embodiment, the clamping structure 3012 includes a mounting groove 302 carefully opened on the placement plate 3011. The mounting groove 302 is slidably connected to the sliding clamp 3021 for firmly clamping and fixing the workpiece body 2. The bottom of the sliding clamp 3021 is firmly fixedly connected to the connecting block 3022. By opening the mounting groove 302 on the placement plate 3011, a precise sliding track is provided for the sliding clamp 3021, enabling the sliding clamp 3021 to move stably along a predetermined direction, ensuring the accuracy of the clamping position. At the same time, the sliding connection method also facilitates flexible adjustment of the clamping position according to the size of different workpieces, improving the versatility and applicability of the fixture.

[0036] To enable the sliding clamp 3021 to automatically reset and clamp, in this embodiment: a stop spring 303 is securely fixedly connected to the side of the sliding clamp 3021, and the other end of the stop spring 303 is securely fixedly connected to the side of the inner wall of the placement frame 301. A stop pad 3031 is fixedly connected to the other side of the sliding clamp 3021. The setting of the stop spring 303 enables the sliding clamp 3021 to have the characteristic of automatic reset. After the external force is released, it can quickly return to the initial position and clamp the workpiece, which greatly improves the efficiency and convenience of clamping. The stop pad 3031 plays a role in protecting the workpiece, avoiding direct contact between the sliding clamp 3021 and the workpiece and causing damage. At the same time, it can also increase the clamping friction and make the clamping more stable.

[0037] To prevent the sliding clamp 3021 from shifting during sliding, in this embodiment: a limiting slide rod 3032 for precisely limiting the sliding clamp 3021 is firmly fixedly connected to the inner wall of the mounting groove 302, and the limiting slide rod 3032 is slidably connected to the sliding clamp 3021. The presence of the limiting slide rod 3032 effectively limits the sliding range of the sliding clamp 3021, preventing it from shifting or shaking during sliding, ensuring the stability and accuracy of the movement of the sliding clamp 3021, thereby improving the clamping accuracy and quality, and ensuring that the workpiece can maintain a stable state during testing.

[0038] To facilitate the operator's opening and closing of the sliding clamp 3021, in this embodiment, an operating component 3013 for driving the sliding clamp 3021 is also installed on the side of the placement frame 301. The operating component 3013 includes a mounting base 304 firmly fixedly connected to the side of the placement frame 301. A sliding pull rod 3041 is slidably connected to the mounting base 304. A driving block 3042 is fixedly connected to the side of the sliding pull rod 3041. Two pull ropes 3043 are fixedly connected to the side of the driving block 3042, and the two pull ropes 3043 are respectively fixedly connected to two connecting blocks 3022. The design of the operating component 3013 provides the operator with a convenient and efficient way to drive the sliding clamp 3021. By pulling the sliding pull rod 3041, the driving block 3042 and the pull ropes 3043 can be moved, thereby pulling the connecting blocks 3022 to separate the sliding clamp 3021. The operation is simple and easy to understand, requiring no complicated skills or tools, greatly improving the convenience and efficiency of operation.

[0039] To ensure that the pull rope 3043 can smoothly pull the connecting block 3022, in this embodiment, a guide wheel 3044 is provided on the inner wall of the placement frame 301 at the position corresponding to one of the pull ropes 3043. The guide wheel 3044 changes the force direction of the pull rope 3043, reduces the friction and resistance of the pull rope 3043 during the pulling process, and enables the pull rope 3043 to pull the connecting block 3022 more smoothly, improving the smoothness and reliability of the operation, and also extending the service life of the pull rope 3043.

[0040] The working principle of this utility model is as follows:

[0041] The operator first grasps the sliding lever 3041 and pulls it outward. The sliding lever 3041 moves the drive block 3042 along with it. The drive block 3042 then pulls the two connecting blocks 3022 through two ropes 3043, thereby causing the two sliding clamps 3021 to separate along the mounting groove 302. At this time, the workpiece body 2 to be tested is placed stably on the placement plate 3011 on the inner wall of the placement frame 301. Next, the sliding lever 3041 is released. Under the elastic force of the abutment spring 303, the sliding clamp 3021 will automatically return to its original position along the limit slide bar 3032. The abutment pad 3031 on its side will clamp the workpiece body 2 securely and conveniently from the side, preparing for the subsequent vibration test.
