Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to an elastic force detection mechanism. Background Art

[0002] Elasticity testing equipment is used to measure the elastic properties of materials after being subjected to stress, including parameters such as elastic modulus, elastic limit, and elastic recovery. Elastic force is a key test item. Whether the elastic force meets the required requirements can help researchers and engineers evaluate material performance and make accurate decisions during the design and production process. Existing technologies generally use manual testing, while some use automated mechanical testing equipment. However, these testing devices are large, complex to operate, and require complex feedback systems.

[0003] Therefore, it is necessary to design an elastic force detection mechanism. Utility Model Content

[0004] In view of the defects in the prior art, the utility model provides an elastic force detection mechanism.

[0005] The technical solution adopted by the utility model is: an elastic force detection mechanism, including a base plate, a vertical lifting mechanism is installed on the base plate, the vertical lifting mechanism is connected to a mounting seat, a voice coil motor is arranged on the mounting seat, the vibration end of the voice coil motor is matched with a cross bar, a test push rod for detecting elastic force is installed on the cross bar, and a pressure sensor close to the voice coil motor is arranged on the cross bar.

[0006] In order to better implement the present invention, a horizontal plate located above the horizontal bar is provided on the top of the mounting seat, and a positioning rod vertically downward for positioning the product to be tested is provided on the horizontal plate, and corresponding positioning holes are provided on the product to be tested.

[0007] In order to better realize the present invention, there are two positioning rods, which are respectively located on both sides of the test push rod.

[0008] In order to better realize the present invention, the vertical lifting mechanism includes a telescopic cylinder, which is equipped with a telescopic rod, and the telescopic rod is fixedly connected to the mounting seat.

[0009] In order to better realize the present invention, the voice coil motor adopts LC445-37-00A.

[0010] In order to better implement the present invention, a plurality of mounting threaded holes are provided on the base plate and matched with corresponding screws.

[0011] The beneficial effects of the present invention are as follows: The present invention provides an elastic force detection mechanism, which, through the coordination of a base plate, a vertical lifting mechanism, a mounting seat, a voice coil motor, a crossbar, a test push rod, and a pressure sensor, is such that, during use, the vertical lifting mechanism positions the mounting seat in its initial state upward. When the product carrier drives the product to be tested to the test position, the vertical lifting mechanism actuates, causing the mounting seat to descend. At this point, the voice coil motor operates, pushing the crossbar, thereby actuating the test push rod, causing it to contact and squeeze the spring of the product to be tested, generating elastic force. The real-time elastic force value can be read via the pressure sensor. This device has the characteristics of a simple structure and convenient testing, and can be used in both automated production lines and manual operations, with strong practicality. It also significantly reduces its size and weight, is easy to install, and offers simple and efficient control, as well as convenient debugging and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example:

[0021] like Figure 1 As shown, a spring force detection mechanism of the present invention includes a base plate 1, on which is mounted a vertical lifting mechanism. The vertical lifting mechanism is connected to a mounting base 3, on which a voice coil motor 4 is mounted. The vibrating end of the voice coil motor 4 is coupled to a crossbar 6, on which a test push rod 7 for detecting spring force is mounted. A pressure sensor 5 is disposed on the crossbar 6 near the voice coil motor 4. The spring force detection mechanism of the present invention cooperates with the base plate 1, the vertical lifting mechanism, the mounting base 3, the voice coil motor 4, the crossbar 6, the test push rod 7, and the pressure sensor 5. During use, the vertical lifting mechanism initially positions the mounting base 3 upward. When a product carrier carries a product to be tested 9 to a test position, the vertical lifting mechanism activates, lowering the mounting base 3. At this time, the voice coil motor 4 operates, pushing the crossbar 6, thereby actuating the test push rod 7. This causes the test push rod 7 to contact and squeeze the spring sheet of the product to be tested 9, generating a spring force. The real-time spring force value can be read by the pressure sensor 5. It has the characteristics of simple structure and easy testing. It can be used in automated production lines and manual operations and is highly practical. It greatly reduces the size and weight and is easy to install. It has simple and efficient control and is easy to debug and maintain.

[0022] As a preferred embodiment, a horizontal plate is provided on the top of the mounting base 3, positioned above the crossbar 6. A positioning rod 8 is provided on the horizontal plate, pointing vertically downward, for positioning the product 9 to be tested. The product 9 to be tested is provided with corresponding positioning holes. This design facilitates positioning and ensures test accuracy. It should be noted that if the product 9 to be tested is large, positioning holes can be pre-set on the product 9 to be tested. If the product 9 to be tested is small, positioning holes can be provided on the carrier of the product 9 to be tested.

[0023] As a preferred embodiment, there are two positioning rods 8, which are respectively located on both sides of the test push rod 7. After such design, the two positioning rods 8 play a better positioning role and will not interfere with the movement of the test push rod 7.

[0024] As a preferred embodiment, the vertical lifting mechanism includes a telescopic cylinder 2 equipped with a telescopic rod fixedly connected to a mounting base 3. Before testing, the telescopic rod of the telescopic cylinder 2 rises, driving the mounting base 3 upwards, allowing the product 9 to safely and smoothly reach the testing position. The telescopic rod then retracts, lowering the mounting base 3 and allowing the test push rod 7 to reach the appropriate position. At this time, the voice coil motor 4 operates, pushing the crossbar 6, thereby driving the test push rod 7, causing the test push rod 7 to contact and squeeze the spring of the product 9 to generate an elastic force. The real-time elastic force value can be read by the pressure sensor 5.

[0025] As a preferred embodiment, the voice coil motor 4 adopts LC445-37-00A, which has the advantages of good stability and high precision.

[0026] As a preferred embodiment, a plurality of mounting threaded holes are provided on the base plate 1 and matched with corresponding screws. After such design, the entire device can be conveniently installed and fixed.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
