For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] As described in the background technology, springs in the prior art are widely used in various places as a common part in production and life. The detection of torque is one of the indispensable steps in the production of springs. At present, it is difficult to detect the torque of springs, and the detection efficiency is relatively low. It is difficult to quickly and effectively perform torque detection on the produced springs.

[0036] Based on this, the present invention provides a spring torque detection device, which is mainly composed of a detection component and an electronic control component. The detection component can be used to detect the torque of the spring, and the electronic control component is used to control the detection component and perform data analysis. The detection component includes a driving mechanism, a detection mechanism and an extrusion mechanism. The driving mechanism provides a driving force for the deformation of the spring. The detection mechanism is located on the upper side of the driving mechanism and is used to detect the rotation angle of the spring. The extrusion mechanism is located on the upper side of the detection mechanism and is used to squeeze the spring. The present invention has a simple structure and is easy to operate. When in use, it can perform torque detection on the spring and perform data analysis. Compared with traditional detection methods, it is convenient and fast, has smaller errors and more accurate data, and is also more efficient.

[0037] The following is combined with specific Figure 1-6 The technical solution of the present invention is described in detail.

[0038] The spring torque detection device of the present invention is mainly used for detecting the torque of an arc spring.

[0039] like Figure 1 As shown, the spring torque detection device includes a bracket 1, a detection component 2 and an electronic control component 3 are provided in the middle of the bracket 1, the detection component 2 is located on the left side of the bracket 1, and the electronic control component 3 is located on the right side of the bracket 1, the detection component 2 is used to detect the torque of the arc spring, and the electronic control component 3 is electrically connected to the detection component 2 for controlling the detection component 2 and can also perform data analysis.

[0040] The detection assembly 2 includes a driving mechanism 23, a detection mechanism 22 and a pressing mechanism 21. Figure 3 As shown, the driving mechanism 23 provides driving force for the deformation of the arc spring, the detection mechanism 22 is located on the upper side of the driving mechanism 23 and is used to detect the rotation angle of the arc spring, and the pressing mechanism 21 is located on the upper side of the detection mechanism 22 and is used to press the arc spring.

[0041] like Figure 1 As shown, the electric control component 3 includes an electric control board 33 located in the middle of the right end of the bracket 1, the upper end surface of the electric control board 33 is fixedly connected to the display screen 31, the lower end of the electric control board 33 is fixedly connected to the electric control box 32, the electric control box 32 is electrically connected to the detector 224, the signal of the detector 224 is obtained, and the result is displayed on the display screen 31 after calculation. This structure can calculate the data detected on the left side on the right side, and the space can be reasonably used.

[0042] Since the main components of the present invention are the detection component 2 and the electronic control component 3, the structure is simple and the operation is convenient. When in use, it can perform torque detection on the arc spring and perform data analysis. Compared with the traditional detection method, it is more convenient and faster, has smaller errors and more accurate data, and is also more efficient.

[0043] Specifically, as shown in Figure 3, the bracket 1 is provided with a support plate 24, which is located in the middle of the bracket 1. The detection component 2 is installed on the left side of the support plate 24, and the electric control component 3 is installed on the right side of the support plate 24. The extrusion mechanism 21 includes a bottom plate 211 and an extrusion disc 212. The bottom plate 211 is fixedly mounted on the upper end surface of the middle position of the left side of the support plate 24. The middle upper end surface of the bottom plate 211 is rotatably connected to the extrusion disc 212. A top block 213 is fixedly provided on the extrusion disc 212, and a push block 2181 is also slidably provided. The arc track 2121 between the top block 213 and the push block 2181 is used to accommodate the arc spring of the torque to be measured, that is, the top block 213 supports one end of the arc spring, and the push block 2181 slides freely to support the other end of the arc spring at an appropriate position.

[0044] like Figure 3 As shown, the arc track 2121 extends along the curvature of the outer edge of the extrusion disk 212 .

[0045] In order to provide the pushing block 2181 with a driving force to slide back and forth along the arc track 2121 and to support the pushing block 2181 at an appropriate position, the extrusion mechanism 21 also includes a pushing block adjusting component, which is placed above the pushing block 2181 and is drivingly connected to the pushing block 2181.

[0046] The push block adjustment component specifically includes a connecting block 216, a threaded rod 215, a fixed rod 217 and a mounting plate 214. The mounting plates 214 are vertically fixedly installed on both sides of the base plate 211. The two mounting plates 214 are arranged in parallel, and the distance between them is the width of the base plate 211. The fixed rod 217 includes two rods, and the ends thereof are installed on the two mounting plates 214. The threaded rod 215 is located between the two fixed rods 217, and the ends are rotatably connected to the mounting plates 214, and one of the ends is installed with an adjustment handle 2151. The two fixed rods 217 and the threaded rod 215 all pass through the connecting block 216.

[0047] Among them, the fixing rod 217 passes through the connecting block 216 in a movable manner, and its main function is to guide and fix the connecting block 216. The threaded rod 215 passes through the connecting block 216 in a threaded connection. By turning the adjustment handle 2151, due to the rotation of the threaded rod 215, the connecting block 216 can move along the length direction of the threaded rod 215.

[0048] A squeezing rod 218 extending into the arc track 2121 is provided on one side of the connecting block 216. The movement of the connecting block 216 drives the squeezing rod 218 to move in the arc track 2121. A pushing block 2181 is provided at the end of the squeezing rod 218. The movement of the squeezing rod 218 drives the pushing block 2181 to slide, and the pushing block 2181 squeezes the arc spring at an appropriate position.

[0049] It should be noted that the connection between the push block 2181 and the push block adjustment component is a detachable connection, which is specifically achieved by the extrusion rod 218. Figure 3 As shown, the connection between the connecting block 216 and the extrusion rod 218 is a detachable connection, which can adapt to different arc springs, that is, different extrusion rods 218 and the pushing block 2181 located at the end of the extrusion rod 218 can be replaced according to different arc spring models.

[0050] The detachable connection is preferably a screw connection, such as Figure 3 As shown, the connection block 216 is provided with a mounting hole, the extrusion rod 218 passes through the mounting hole, and the screw rod 219 is inserted from the side of the connection block 216, and the end thereof abuts against the extrusion rod 218 in the connection block 216, thereby fixing the extrusion rod 218 to the connection block 216.

[0051] When testing is required, the arc spring to be tested is placed in the arc track 2121 of the extrusion disk 212, one end of the arc spring is pressed against the top block 213, and the other end is pressed against the push block 2181, and the threaded rod 215 can be rotated by manually turning the adjustment handle 2151. The threaded rod 215 rotates, driving the connecting block 216 and the structure connected to its upper side to move along its length direction, thereby adjusting the position of the push block 2181 to find a suitable position for the arc spring.

[0052] like Figure 4 As shown, the connecting block 216 includes a bottom block 2162 and a top block 2161, the threaded rod 215 passes through the bottom block 2162, the fixing rod 217 passes through the joint of the bottom block 2162 and the top block 2161, and an anti-loosening member is provided on the top block 2161, and the anti-loosening member is rotatably inserted into the bottom block 2162 from the top block 2161. The anti-loosening member is preferably a screwing screw 2163. When the connecting block 216 slides on the fixing rod 217, there is a gap between the top block 2161 and the bottom block 2162. When the pushing block 2181 reaches the appropriate position, the screwing screw 2163 is screwed downward, and the gap between the bottom block 2162 and the top block 2161 gradually decreases. When it reaches a stuck state, the connecting block 216 cannot move.

[0053] Specifically, Figure 5 and Figure 6As shown, the detection mechanism 22 includes a connecting disk 222, which is fixedly arranged below the extrusion disk 212, and a rotor 223 is fixedly connected to the bottom of the connecting disk 222. A detector 224 for detecting the rotation angle of the rotor 223 is provided on one side of the rotor 223. A fixing plate 225 is fixedly connected to the rear lower end surface of the base plate 211, and the detector 224 is fixedly connected to the upper front end surface of the fixing plate 225. The detector 224 is electrically connected to the electronic control component 3, that is, the rotation angle data of the rotor 223 is transmitted to the electronic control component 3 through the detector 224, so that the electronic control component 3 can analyze and control it. A coupling 226 is fixedly provided below the rotor 223.

[0054] This structure allows the rotation of the upper extrusion disk 212 to be determined by detecting the rotation angle of the rotor 223, and the setting of the coupling 226 allows a certain degree of shaking when the lower side is not completely perpendicular to the upper side, so as to avoid the shaking having an adverse effect on the upper structure.

[0055] More specifically, Figure 5 and Figure 6 As shown, the driving mechanism 23 includes a fixing ring 231 fixedly connected to the lower end surface of the base plate 211 and passing through the support plate 24. The rotor 223 in the detection component 2 and the structure on its lower side are surrounded by the fixing ring 231. The lower end surface of the fixing ring 231 is fixedly connected to the reducer 232. The lower end surface of the reducer 232 is fixedly connected to the motor 233. The reducer 232 and the coupling 226 are dynamically connected via a flange 227.

[0056] When the motor 233 rotates, the flange 227 and the structure on its upper side are driven to rotate together through the reducer 232, so that the extrusion disk 212 is finally rotated to squeeze the arc spring placed in the extrusion disk 212. When it is squeezed to the point where it can no longer rotate, the detector 224 can be used to determine the rotation angle, and then the torque of the arc spring can be calculated. This structure can accurately measure the torque of the arc spring and maintain stable efficiency.

[0057] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
