[0014] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] Example

[0016] In order to solve the above technical problems, this embodiment provides a spring strength detection device, such as Figure 1As shown, it includes a mounting seat 10 and a mounting frame 20 arranged on both sides of the mounting seat 10. A plurality of positioning grooves 11 for installing the spring to be detected are arranged on the surface of the mounting seat 10. The mounting frame is located on the upper side of the mounting seat and is slidably connected with a pressure block 21 for squeezing the spring to be detected. A scale groove 22 is arranged on the side of the mounting frame 20. By placing the spring to be detected in the positioning groove 11 and then placing a counterweight block 214 on the pressure block 21, the pressure block 21 is driven to move toward the spring to be detected and press down on the spring to be detected. After the spring to be detected is squeezed, by observing the position of the pressure block 21 in the scale groove 22, the spring to be detected is judged whether the hardness of the spring to be detected is within the qualified range under the gravity of the counterweight block 214, thereby saving equipment costs while achieving the detection accuracy required for production.

[0017] As a preferred embodiment, a slide groove 23 is further provided on the side of the mounting frame 20, and a plurality of groups of rollers 211 for guiding the pressing block 21 are provided on both sides of the pressing block 21. The rollers 211 are slidably arranged in the slide groove 23. By arranging the rollers 211, when a counterweight block 214 is placed on the pressing block 21, the rollers 211 drive the pressing block 21 along the slide groove 23 to approach the spring to be detected. The rollers 211 on both sides of the pressing block 21 guide the pressing block 21 to avoid tilting of the pressing block 21 during the lifting and lowering movement on the mounting frame 20, thereby ensuring that the pressing block 21 presses down on the spring to be detected, thereby reducing the error of the detection result.

[0018] As a preferred embodiment, the pressing block 21 is detachably connected to the mounting block 213 , and the roller 211 is rotatably connected to the mounting block 213 , so that the device can be disassembled, which is convenient for replacement and maintenance of the roller 211 .

[0019] In order to adapt to the testing of springs of different sizes, as a preferred embodiment, the sizes of the plurality of positioning slots 11 are different. By setting a plurality of positioning slots of different sizes, the device can be compatible with testing of multiple springs of different sizes, thereby improving compatibility.

[0020] In order to provide power to squeeze the spring, as a preferred embodiment, a receiving groove 212 is provided at the top of the pressure block 21, and a plurality of counterweights 214 are provided in the receiving groove 212. By providing the receiving groove 212, when the counterweight 214 is placed in the receiving groove 212, the pressure block 21 moves downward and presses down on the spring to be tested under the action of gravity, so that the pressure block 21 squeezes the spring. After being in a stationary state, the position of the corresponding scale groove of the pressure block is observed, and then it is determined whether the hardness of the tested spring is within the qualified range. In the specific embodiment, the counterweights 214 of different weights can be replaced, and then different types of springs can be tested to achieve the purpose of improving compatibility.

[0021] To summarize, in one or more embodiments of the present application, the present application provides a spring strength detection device, including a mounting seat, and a mounting frame arranged on both sides of the mounting seat, a plurality of positioning grooves for installing the spring to be detected are provided on the surface of the mounting seat, the mounting frame is located on the upper side of the mounting seat and is slidably connected with a pressure block for squeezing the spring to be detected, and a scale groove is provided on the side of the mounting frame. By placing the spring to be detected in the positioning groove and then placing a counterweight block on the pressure block, the pressure block is driven to move toward the spring to be detected and press down on the spring to be detected. After the spring to be detected is squeezed, the position of the pressure block corresponding to the scale groove is observed to determine whether the hardness of the spring to be detected is within the qualified range, thereby saving equipment costs while achieving the detection accuracy required for production.

[0022] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
