Description

Technical Field

[0001] The utility model relates to the technical field of tensile machines, in particular to an intelligent electronic tensile machine for film performance testing. Background Art

[0002] With the continuous advancement of science and technology and the increasing application of thin film materials, the requirements for accuracy and efficiency in thin film performance testing are becoming increasingly stringent. Against this backdrop, electronic tensile testing machines, a device specifically designed to test the mechanical properties of thin film materials, have gradually become a crucial tool for thin film performance testing. The operating principle of an electronic tensile testing machine typically involves clamping a film specimen between two chucks in a fixture, which are then driven by a mechanism to cause the chucks to move relative to each other. During this movement, force sensors located on the dynamic chucks and displacement sensors built into the machine collect force and displacement data in real time. After computer processing, this data can be used to determine performance indicators such as the film's tensile strength, tear strength, and deformation rate.

[0003] When some existing electronic tensile testing machines are in use, the clamping mechanism thereon adopts a relatively simple mechanical structure. The clamping mechanism needs to be adjusted manually, the operation process is relatively cumbersome, and the adjustment accuracy is difficult to ensure, which is not conducive to improving testing efficiency.

[0004] For example, the electronic tensile testing machine disclosed in the announcement number CN216955464U is used to detect the performance of plastic films. When testing the plastic film, the electronic tensile testing machine of this patent uses a dynamic clamp to clamp the upper end of the plastic film. When clamping the plastic film at the upper end, the plastic film can enter the clamping groove through the clamping opening on the side of the clamping body, which is convenient for clamping the upper end of the plastic film. Then, the fixed clamp is used to clamp the lower end of the plastic film, and then the driving block is driven to slide by the driving motor to make the dynamic clamp move relative to the fixed clamp to stretch the plastic film. During the stretching process, the force sensor detects the data generated when the plastic film is stretched, and the computer processes and displays the data after receiving it.

[0005] Although the patented electronic tensile testing machine is equipped with components such as a clamping body, a clamping block, an interference rod and a fastening screw to clamp the film, the operator still needs to manually adjust these components to accommodate films of different sizes and types. This means that before each test, the operator needs to spend time adjusting the clamping mechanism, which not only increases the complexity of the operation but also may introduce human errors.

[0006] Therefore, it is necessary to invent an intelligent electronic tensile testing machine for film performance testing to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide an intelligent electronic tensile testing machine for film performance testing to solve the problems in the above technology.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent electronic tensile testing machine for film performance testing, comprising a testing workbench and a clamping mechanism, wherein the top of the testing workbench is fixedly connected with an L-shaped bracket plate, a ball screw is rotatably connected between the L-shaped bracket plate and the testing workbench, a No. 2 motor is installed on the top of the L-shaped bracket plate, the output shaft of the No. 2 motor is transmission-connected to the top end of the ball screw, a lifting block is transmission-connected to the surface of the ball screw, a force sensor is fixedly connected to the bottom of one end of the lifting block, the clamping mechanism is arranged on one side of the ball screw, and the number of the clamping mechanisms is set to two, one of which is One of the clamping mechanisms is installed on the top of the detection workbench, and the other clamping mechanism is installed on the bottom of the force sensor. The clamping mechanism includes a base base, a No. 1 limiting slide groove is provided on the surface of the base base, and a two-way screw is rotatably connected inside the No. 1 limiting slide groove. The surface of the two-way screw is transmission-connected to two moving blocks, and the bottom ends of the two moving blocks are slidingly connected to the No. 1 limiting slide groove.

A No. 1 motor is installed at one end of the base base, and the output shaft of the No. 1 motor is transmission-connected to one end of the two-way screw.

[0009] The No. 1 motor drives the bidirectional lead screw, so that the two moving blocks can slide smoothly in the No. 1 limit slide, thereby driving the clamping plate to clamp or release the film. This design not only has a stable clamping but also is easy to operate and is suitable for films of different sizes.

[0010] Preferably, one side of the rubber pad is provided with anti-skid corrugations, the anti-skid corrugations are serrated in shape, and the anti-skid corrugations on the two rubber pads can mesh with each other.

[0011] The anti-slip corrugated design on the rubber pad increases the friction during clamping, ensuring that the film is stable and does not slip during the test, thereby improving the accuracy of the test. The serrated anti-slip corrugated design enables the two rubber pads to engage with each other, further enhancing the stability of the clamping.

[0012] Preferably, a bolt is fixedly connected to the other side of the rubber pad, a through hole is opened on the surface of the clamping plate, and the bolt is arranged to pass through the through hole.

[0015] The design of the hand-tightening nut allows the rubber pad to be easily removed from the splint and replaced.

[0016] Preferably, a control button is installed on the surface of the base, and the control button is electrically connected to the No. 1 motor.

[0017] The electrical connection between the control button and the No. 1 motor allows the operator to easily control the opening and closing of the clamping mechanism, thereby improving the convenience of operation.

[0018] Preferably, a No. 2 limiting slide groove is provided on the surface of the L-shaped bracket plate, and the end of the lifting block away from the force sensor is slidably connected to the No. 2 limiting slide groove.

[0019] The No. 2 limiting slide groove design on the L-shaped bracket plate ensures the stability of the lifting block during movement.

[0020] Preferably, a lifting frame is fixedly connected to one side of the L-shaped bracket plate, a control panel is installed on the top of the lifting frame, and the force sensor and the second motor are electrically connected to the control panel.

[0021] The design of the support frame and control panel allows the operator to easily operate and control the entire test process. The integrated design of the control panel also improves the intelligence of the equipment.

[0022] Preferably, a storage space is provided inside the detection workbench, and a cabinet door is installed on the surface of the detection workbench.

[0023] The storage space inside the inspection workbench and the cabinet door design on the surface provide operators with convenient storage for tools and accessories, making the working environment more tidy and orderly.

[0024] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0025] 1. The clamping mechanism adopts a motor-driven design. The No. 1 motor controls the rotation of the bidirectional lead screw, thereby driving the two moving blocks to slide smoothly along the No. 1 limit slide, realizing the automatic opening and closing of the splint. This automated control not only improves the convenience of operation, but also reduces the errors caused by human factors, ensuring the accuracy and stability of clamping.

[0026] 2. The rubber pad in the clamping mechanism is uniquely designed. The anti-slip corrugations on it can effectively increase the friction during clamping, preventing the film from slipping during testing. At the same time, the softness of the rubber pad can also protect the film surface and reduce damage caused by clamping. BRIEF DESCRIPTION OF THE DRAWINGS
