Description

Technical Field

[0001] This application relates to the field of testing tooling technology, and in particular to a robustness testing device. Background Technology

[0002] In industrial production, the robustness of connections in medical products such as occluders and shunts is one of the core indicators for measuring their reliability and safety. Traditional testing methods often involve manual operation, such as manually applying tension or suspending a fixed weight for loading tests.

[0003] However, such methods have the following significant drawbacks: insufficient testing accuracy, difficulty in ensuring consistency of force direction and speed during manual operation, and easy introduction of testing deviations; low efficiency, requiring repeated adjustment of counterweights and manual loading and unloading of workpieces, making continuous batch testing impossible; and safety risks, as workpieces are prone to fall off due to operational errors when manually clamped, posing a safety hazard.

[0004] Therefore, there is an urgent need to develop a robustness testing device that combines high testing accuracy, high stability, ease of operation, and testing efficiency. Utility Model Content

[0005] This application provides a firmness testing device to solve the problems of low testing accuracy, low stability, inconvenient operation, and low testing efficiency of manual testing of workpiece firmness.

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a firmness testing device. This firmness testing device includes: a lifting component; a pneumatic chuck connected to the drive end of the lifting component for clamping one end of a workpiece to be tested; and a counterweight connected to the other end of the workpiece to be tested. The lifting component is used to drive the pneumatic chuck to rise when it clamps one end of the workpiece to be tested, thereby lifting the workpiece to be tested and the counterweight.

[0007] In some embodiments, the firmness testing device further includes a mounting plate and a stroke shaft, the mounting plate being fixed to the drive end of the lifting member, and the pneumatic chuck being mounted on the mounting plate;

[0008] The travel shaft is vertically arranged, and the mounting plate is slidably engaged with the travel shaft and slides along the travel shaft under the drive of the lifting component.

[0009] In some embodiments, the firmness testing device further includes a pneumatic control switch for controlling the opening and closing of the pneumatic clamp.

[0010] In some embodiments, the pneumatic chuck includes two gripping fingers, each gripping finger is fitted with a protective sleeve, and the workpiece to be tested is gripped by the protective sleeve.

[0011] In some embodiments, the protective sleeve is a flexible protective sleeve.

[0012] In some embodiments, the lifting element is a cylinder.

[0013] In some embodiments, the robustness testing device further includes a mounting bracket for securing the cylinder.

[0014] In some embodiments, the mounting bracket includes a base, a top seat, and a plurality of support rods. The bottom end of the cylinder is mounted on the base, the top seat is mounted on the top end of the cylinder, and the plurality of support rods connect the base and the top seat.

[0015] The beneficial effects of this application are as follows: Unlike the prior art, this application discloses a strength testing device. One end of the workpiece to be tested is held by a pneumatic chuck, and the other end of the workpiece is connected to a suitable counterweight. A lifting component drives the pneumatic chuck to rise, lifting the workpiece and the counterweight. After the rise is complete, the lifting component resets. During this process, if the workpiece does not break, it indicates that the workpiece itself is firmly connected and meets the strength standard. If the workpiece breaks, it indicates that its strength is insufficient. By using the strength testing device provided by this application, the strength of each workpiece can be conveniently and efficiently tested, allowing for the removal of workpieces that do not meet the preset strength standard, ensuring the quality reliability of each workpiece. Furthermore, the testing process does not require manual intervention, thus eliminating test deviations introduced by human intervention, maintaining consistent application direction and speed during testing, and ensuring sufficiently high test stability.

[0021] This application provides a strength testing device 100, see reference. Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the robustness testing device provided in this application.

[0022] The firmness testing device 100 includes a lifting member 10, a pneumatic chuck 20, and a counterweight 30. The pneumatic chuck 20 is connected to the drive end of the lifting member 10 and is used to clamp one end of the workpiece 01 to be tested. The counterweight 30 is used to connect the other end of the workpiece 01 to be tested. The lifting member 10 is used to drive the pneumatic chuck 20 to rise when the pneumatic chuck 20 clamps one end of the workpiece 01 to be tested, so as to lift the workpiece 01 to be tested and the counterweight 30.

[0023] In this embodiment, the workpiece 01 to be tested can be a medical device such as a occluder or a shunt. By testing with the firmness testing device 100, it can be determined whether these workpieces 01 to be tested meet the preset firmness standard.

[0024] The lifting component 10 can be a cylinder or an electric push rod, and its driving end is connected to the pneumatic chuck 20, which can drive the pneumatic chuck 20 to lift.

[0025] The pneumatic chuck 20 can be used to clamp the workpiece 01 to be tested, and to release the clamped workpiece 01 to be tested.

[0026] The counterweight 30 includes weights of different masses to suit different testing needs. For example, the counterweight 30 can be equipped with different weights such as 5kg, 10kg, or 15kg.

[0027] For example, to test the firmness of the plugging device under 5 kg, a pneumatic chuck 20 clamps one end of the plugging device, and a counterweight 30 is connected to the other end. The lifting component 10 drives the pneumatic chuck 20 to rise, thereby lifting the plugging device and the counterweight 30. After the rise is completed, the lifting component 10 returns to its original position. If the plugging device does not break during this process, it indicates that the plugging device itself is firmly connected and meets the firmness standard. If the plugging device breaks, it indicates that its firmness is insufficient.

[0028] The above method can conveniently and efficiently detect the firmness of each workpiece 01 to be tested, so as to remove the workpiece 01 that does not meet the preset firmness standard, ensure the quality reliability of each workpiece 01, and avoid potential problems in actual application.

[0029] In this embodiment, the pneumatic chuck 20 includes two clamping fingers 22, and a protective sleeve 23 is installed on the clamping fingers 22, and the workpiece 01 to be tested is clamped through the protective sleeve 23.

[0030] The protective sleeve 23 is a flexible protective sleeve made of flexible material, which can avoid damage to the workpiece 01 when clamping it.

[0031] Optionally, the protective sleeve 23 can also be made of a non-slip material to enhance clamping stability, ensure that the workpiece 01 does not slip during the test, and improve test accuracy and safety.

[0032] In this embodiment, the lifting component 10 is a cylinder, which can be linked with the pneumatic chuck 20. After the pneumatic chuck 20 clamps the workpiece 01 to be tested, the lifting component 20 can directly start the lifting action, thereby simplifying the operation process and improving the testing efficiency.

[0033] Furthermore, the firmness testing device 100 also includes a pneumatic control switch 40, which is used to control the opening and closing of the pneumatic chuck 20. The user can operate the pneumatic control switch 40 to close the pneumatic chuck 20 and clamp the workpiece 01 to be tested. When the lifting member 10 is holding one end of the workpiece 01 in the pneumatic chuck 20, it drives the pneumatic chuck 20 to rise, thereby lifting the workpiece 01 and the counterweight 30 for the firmness test. After the test is completed, the user operates the pneumatic control switch 40 again to open the pneumatic chuck 20 and release the workpiece 01.

[0034] The firmness testing device 100 also includes a mounting plate 51 and a stroke shaft 52. The mounting plate 51 is fixed to the drive end of the lifting member 10, and the pneumatic chuck 20 is mounted on the mounting plate 51. The stroke shaft 52 is vertically arranged, and the mounting plate 51 slides in cooperation with the stroke shaft 52 and slides along the stroke shaft 52 under the drive of the lifting member 10.

[0035] Mounting plate 51 not only supports pneumatic chuck 20, but also serves as a guide that slides with stroke shaft 52, thereby ensuring that lifting component 10 can stably drive pneumatic chuck 20 to lift and lower in the vertical direction. This can greatly improve the lifting accuracy of lifting component 10, reduce the accuracy loss of lifting component 10 due to frequent testing, and extend its service life.

[0036] The robustness testing device 100 also includes a mounting bracket 60 for fixing the cylinder to support the cylinder 10 in stably completing the operation.

[0037] The fixing frame 60 includes a base 61, a top seat 62 and multiple support rods 63. The bottom end of the cylinder 10 is mounted on the base 61, the top seat 62 is mounted on the top end of the cylinder 10, and the multiple support rods 63 connect the base 61 and the top seat 62.

[0038] The base 61 is also fixed to a support platform such as a base plate or desktop, so as to stably and firmly support the entire firmness testing device 100, ensuring that there is no shaking or displacement during the test, thereby improving the testing efficiency.

[0039] One end of the workpiece to be tested is held by a pneumatic chuck, and the other end of the workpiece is connected to a suitable counterweight. A lifting device drives the pneumatic chuck to rise, thereby lifting the workpiece and the counterweight. After the rise is completed, the lifting device returns to its original position. If the workpiece does not break during this process, it indicates that the workpiece itself is firmly connected and meets the strength standard. If the workpiece breaks, it indicates that its strength is insufficient. By using the strength testing device provided in this application, the strength of each workpiece can be conveniently and efficiently tested, so that workpieces that do not meet the preset strength standard can be eliminated, ensuring the quality reliability of each workpiece 01. Moreover, the testing process does not require manual intervention, so there is no test deviation introduced by human intervention. It can maintain the same direction and speed during testing, and the test stability is also high enough.

[0040] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
