Description

Technical Field

[0001] This utility model relates to the field of automated mechanical technology, specifically a bidirectional spring push-pull testing mechanism. Background Technology

[0002] Push-pull testing is an engineering testing method used to evaluate the performance and reliability of materials, devices, or systems under push or pull forces. This test is widely used in various industries, including aerospace, automotive, construction, and manufacturing. In push-pull testing, samples are typically subjected to static or dynamic push or pull forces, which are monitored and recorded during the stress period. The purpose of the test is to determine key performance indicators of the sample under load, such as strength, deformation, fatigue life, and failure point.

[0003] Push-pull force testing is an indispensable dynamic mechanical test for measuring the fixation strength and bonding capability of components. For example, for plate products with a mid-frame, push-pull force testing is often required after welding to check the weld strength. Many existing push-pull force testing devices use manual push-pull methods, but manual pushing and pulling cannot be precisely controlled; while some mechanical testing methods often combine a separate push force testing mechanism and a separate pull force testing mechanism, but this structure is complex and has low testing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a bidirectional spring push-pull testing mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional spring push-pull testing mechanism, including a base plate, a linear module with horizontal left-right transmission on the base plate, a connecting plate connected above the linear module, a slide cylinder with vertical arrangement on the connecting plate, and a testing component connected to the upper end of the slide cylinder;

[0006] The test assembly includes a mounting plate, on which a sliding plate is slidably connected. Several guide rods are horizontally arranged on the mounting plate and pass through the sliding plate. Each guide rod is fitted with two springs located on the left and right sides of the sliding plate. The sliding plate is connected to a horizontally arranged tension and compression sensor, which is connected to a push-pull plate.

[0007] Further preferably, the push-pull plate is provided with several upward-facing inserts for insertion into the product frame, facilitating the pushing or pulling of the product.

[0008] Further preferably, there are two insert teeth, which are spaced apart to facilitate insertion into the product frame and pushing or pulling the product.

[0009] In a further preferred embodiment, a side plate is vertically connected to both the left and right ends of the mounting plate, and the two ends of the guide rod are respectively fixedly connected to the two side plates. The side plates are used for mounting the guide rod and for limiting the spring.

[0010] Further preferably, there are two guide rods, which are arranged parallel to each other front and back, and the two ends of the two guide rods are respectively fixed to the two side plates. The two guide rods can ensure that the sliding plate slides smoothly from left to right.

[0011] In a further preferred embodiment, the sliding plate is provided with a bracket, the tension / compression sensor is installed on the right side of the bracket, and the push-pull plate is located on the right side of the tension / compression sensor. The tension / compression sensor is installed through the bracket, and the position settings of the tension / compression sensor and the push-pull plate ensure that the force generated by the push-pull plate on the product can be measured by the tension / compression sensor.

[0012] Further preferably, the base plate is provided with a support plate, which is located on the front side of the linear module. A second linear guide rail, arranged horizontally, is located above the support plate, and the connecting plate is connected to the second linear guide rail. The support plate is used for mounting the second linear guide rail, which ensures smooth horizontal movement of the connecting plate.

[0013] Beneficial Effects: This utility model's bidirectional spring push-pull testing mechanism uses a linear module as a power source to drive the testing component, which in turn pushes and pulls the product to achieve push-pull testing. The testing component adopts a bidirectional spring structure, meaning that springs are provided on both the left and right sides of the sliding plate. When the linear module moves the mounting plate of the testing component, one of the springs on either side of the sliding plate is compressed. The compression force is displayed by a tension / compression sensor, thus determining the push-pull force on the product. The bidirectional spring structure converts hard push-pull into soft push-pull, ensuring the safety of the testing mechanism and the product. Furthermore, the push-pull force test can be completed in one pass using only the reciprocating motion of the linear module, simplifying the product testing process. The testing is fast, efficient, and structurally simple. This push-pull testing mechanism enables automated testing, avoiding the instability and uncontrollability caused by manual back-end testing.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-3 As shown, a bidirectional spring push-pull testing mechanism is used for testing the push-pull force of a product, and can detect the product's installation firmness. The mechanism includes a base plate 1, on which a linear module 2 with horizontal left-right transmission is mounted. A connecting plate 3 is connected above the linear module 2, and a vertically mounted slide cylinder 4 is mounted on the connecting plate 3. A testing component 5 is connected to the upper end of the slide cylinder 4. The base plate 1 is used for the overall installation of the push-pull testing mechanism. The linear module 2 drives the connecting plate 3 to move left and right, thereby synchronously moving the slide cylinder 4 and the testing component 5, enabling the product to be pushed to the right and pulled to the left. The testing component 5 performs the push-pull test on the product. If the product remains stationary under certain pressure values ​​during both pushing and pulling, the push-pull test is passed, and the product is considered a qualified product.

[0020] In this application, the test component 5 includes a mounting plate 51, a guide rod 54, a sliding plate 55, a spring 56, a tension / compression sensor 58, and a push-pull plate 59. The guide rod 54 is mounted on the mounting plate 51. The sliding plate 55 is slidably connected to the guide rod 54 and the mounting plate 51. Every two springs 56 are sleeved on the left and right sides of the sliding plate 55 on the corresponding guide rod 54. The tension / compression sensor 58 is installed on the side of the sliding plate 55 and is horizontally set. The tension / compression sensor 58 is connected to the push-pull plate 59. By connecting the push-pull plate 59 to the product, the mounting plate 51 is pushed to move. However, since the push-pull plate 59 is connected to the product, and the product is stationary, the product's obstruction and the elastic force of the spring 56 will cause the push-pull plate 59, the tension / compression sensor 58, and the sliding plate 55 to not move synchronously with the mounting plate 51. This will squeeze the tension / compression sensor 58, which displays the real-time pressure value. After reaching the specified pressure value, the linear module 2 stops moving. When the linear module 2 returns to its initial position after pushing to the right and pulling to the left, the test is complete.

[0021] In the solution of this application, the push-pull plate 59 is provided with several upward-facing inserts 591, which can be inserted into the frame of the product, so that the push-pull plate 59 can push or pull the product and realize the push-pull force test of the product.

[0022] Based on the above scheme, there are two insert teeth 591, which are spaced apart to facilitate insertion into the product frame. The two insert teeth 591 are inserted into the corresponding two frames on the product, which can push and pull the product. The left and right movement control of the linear module 2 is realized by the value displayed by the tension and pressure sensor 58.

[0023] In the scheme of this application, a side plate 52 is vertically connected to both the left and right ends of the mounting plate 51. The two ends of the guide rod 54 are fixedly connected to the two side plates 52 respectively. The side plates 52 realize the installation and fixation of the guide rod 54, and at the same time can limit the spring 56. The spring 56 forms elastic buffer and elastic pressure on the sliding plate 55, and the pressure value is displayed by the tension and pressure sensor 58.

[0024] Based on the above scheme, there are two guide rods 54, which are arranged in parallel front to back. The two ends of the two guide rods 54 are respectively fixed to the two side plates 52. The two guide rods 54 can ensure that the sliding plate 55 slides smoothly and steadily from left to right, and at the same time facilitate the installation of the spring 56.

[0025] In the solution of this application, a bracket 57 is provided on the sliding plate 55. The bracket 57 facilitates the installation of the tension and pressure sensor 58. The tension and pressure sensor 58 is installed on the right side of the bracket 57, and the push-pull plate 59 is set on the right side of the tension and pressure sensor 58. This allows the force generated by the push-pull plate 59 pushing or pulling the product to be displayed by the tension and pressure sensor 58, thus ensuring the testing accuracy of the push-pull testing mechanism.

[0026] In the solution of this application, a support plate 6 is provided on the base plate 1. The support plate 6 is located on the front side of the linear module 2. A second linear guide rail 7 is provided above the support plate 6 and arranged on the left and right. The connecting plate 3 is connected to the second linear guide rail 7. The support plate 6 facilitates the installation of the second linear guide rail 7. The support plate 6 and the second linear guide rail 7 form a support for the connecting plate 3, ensuring that the connecting plate 3 slides smoothly from left to right, thereby ensuring that the test component 5 can perform a smooth push-pull test on the product.

[0027] In this application, the workflow of the push-pull testing mechanism is as follows: After the product moves to the designated position above the push-pull testing mechanism, the slide cylinder 4 rises, and the insert teeth 591 of the push-pull plate 59 are inserted into the product's basket. Then, the linear module 2 moves to the right, and the push-pull plate 59 contacts the product. The product 59 generates a leftward reaction force on the push-pull plate 59. At this time, the spring 56 located at the left end of the guide rod 54 is compressed, and the real-time pressure value is displayed on the tension-compression sensor 58. After reaching the designated pressure value, the linear module 2 stops moving to the right. Then, the linear module 2 moves to the left in the opposite direction, pulling the product to the left through the push-pull plate 59. At this time, the spring 56 located at the right end of the guide rod 54 is compressed, and the real-time pressure value is displayed on the tension-compression sensor 58. After reaching the same pressure value, the linear module 2 stops moving. Finally, the linear module 2 returns to the initial position, and the test is completed. If the product remains stationary when the push-pull plate 59 pushes or pulls it, it proves that the product meets the push-pull force test requirements and is a qualified product.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the scope of protection of this utility model.
