Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, specifically to a fixture for testing the strength of ultrasonic welding. Background Technology

[0002] Ultrasonic welding is a process that uses high-frequency vibration energy to join materials. It is widely used in welding materials such as plastics and metals. When using it, the welding strength needs to be tested with a test fixture to ensure the stability of the welding.

[0003] For example, the Chinese authorized patent (welding strength testing device) with publication number CN205484686U includes a rotating disc for driving the workpiece to rotate. The rotating disc is equipped with an insertion structure for inserting the workpiece and allowing it to rotate relative to the disc. One side of the rotating disc has a testing element for the workpiece to abut against during rotation. The side of the testing element that abuts against the workpiece is a working surface, which is an arc or inclined surface that increases the radial pressure on the workpiece as it rotates with the disc. The testing element is connected to an elastic element that bears the force when the workpiece abuts against it. The welding strength testing device provided by this invention can prevent cracked products from flowing to the next process or market, and has high testing reliability.

[0004] However, existing ultrasonic welding strength testing methods mainly include tensile testing, torsion testing, and tearing testing, but most of these methods are destructive tests. Traditional inspection methods rely on the personal experience of testing personnel and operators, and do not form standardized experimental report data, making it difficult to meet the current market demand for diversified product materials, product shapes, and welding processes. Therefore, to address this issue, we propose a fixture for ultrasonic welding strength testing. Utility Model Content

[0005] The purpose of this utility model is to provide a fixture for ultrasonic welding strength testing, in order to solve the problem mentioned in the background art that the existing ultrasonic welding strength testing methods mainly include tensile testing, torsion testing, tearing testing, etc., but most of these methods are destructive tests. Traditional inspection methods rely on the personal experience of the testing personnel and operators, and do not form standardized experimental report data, which makes it difficult to meet the current market conditions for the diversification of product materials, product shapes and welding processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixture for ultrasonic welding strength testing, comprising: a cabinet, a cabinet door provided at the front opening of the cabinet, a clamp provided inside the cabinet, a pressure sensor provided at the upper end of the clamp, a cylinder rod provided at the upper end of the pressure sensor, a cylinder provided at the upper end of the cylinder rod, and the output end of the cylinder drives the cylinder rod to move up and down, the fixture comprising a base and clamping parts, and multiple clamping parts are provided, and the clamping parts slide along the base.

[0007] Preferably, the clamping part includes a triangular seat, a limiting slider is provided on the lower surface of one end of the triangular seat, and limiting grooves are provided on both upper surfaces of the base, and the limiting slider slides along the limiting grooves.

[0008] Preferably, the clamping part further includes a spring rod, the other end surface of the triangular seat is provided with a moving groove, and the spring rod moves along the moving groove. One end of the spring rod is provided with a spring rod soft rubber pressure head, and a spring is provided on the outside of the spring rod.

[0009] Preferably, the other end of the spring rod is provided with a lever, the outside of the triangular seat is provided with a mounting sleeve, the upper surface of the mounting sleeve is provided with an adjustment groove, and the lever moves along the adjustment groove.

[0010] Preferably, the upper end of the base is provided with a base pad, and multiple base pads are provided and stacked one on top of the other.

[0011] Preferably, the cylinder's input terminal is connected to a control panel, the cylinder's bottom end is provided with a mounting plate, and a mounting bracket is provided on one side of the mounting plate.

[0012] Preferably, each of the lower corners of the cabinet is provided with a support leg, and one side of each support leg is provided with a caster wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets the required detection pressure range and detection program through the control panel. According to the instructions of the control unit, the cylinder is started. The output end of the cylinder pushes the cylinder rod to press down. Then the pressure sensor feeds back the real-time pressure data to the control panel. The control panel judges whether the welding strength meets the requirements according to the preset program and real-time data, and outputs the results through the display unit. It can adjust the detection pressure in real time according to different welding materials and process requirements, improve the applicability and accuracy of the detection. Through the adjustable pressure detection method, it solves the problem that the existing ultrasonic welding strength detection methods mainly include tensile test, torsion test, tear test, etc., but most of these methods are destructive tests. Traditional inspection methods rely on the personal experience of the inspectors and operators to judge, and there is no standardized experimental report data. It is difficult to meet the current market conditions for the diversification of product materials, product shapes and welding processes.

[0015] (2) By setting a clamping part inside the mounting sleeve and adjusting it according to the product size, the support height and horizontal position of the product under test can be changed by increasing or decreasing the number of base pads, thereby improving applicability and stability. When the product is placed on the base pad, the spring rod soft rubber pressure head is driven by the force to move the spring rod. The spring plays a buffering and adaptive adjustment role. When the clamping force changes or the product diameter is slightly different, the spring can deform itself to help the spring rod soft rubber pressure head better fit the product and maintain a stable clamping state. At the same time, during the clamping operation, it buffers the instantaneous impact force, protects the product and device structure, and further improves applicability and safety.

[0023] The upper end of the base 9 is provided with base pads 10, and multiple base pads 10 are provided, stacked vertically. The arrangement can be adjusted according to the product size. By increasing or decreasing the number of base pads 10, the support height and horizontal position adaptability of the product under test can be changed. For example, for products with a larger diameter, the number of base pads 10 can be appropriately reduced to lower the support height, allowing the clamping parts 13 on both sides to better encircle the product; for products with a smaller diameter, the number of base pads 10 can be increased to raise the height and ensure clamping effectiveness.
