Abstract
Description
Technical Field
[0001] The utility model belongs to the field of detection technology, and in particular relates to a rapid detection torque meter. Background Art
[0002] Torsion springs are coil springs. Their ends are fixed to other components. When the components rotate about the spring's center, the spring pulls them back to their original position, generating torque, or rotational force. Torsion springs can store and release angular energy or statically fix a device by rotating the moment arm about the spring's central axis. Torsion springs are tested for torque before leaving the factory to ensure they meet product specifications. For example, the application number CN218470047U is a lightweight measuring tool for detecting torque of a torsion spring. The tool includes, from left to right, a left fixed base plate with torque measurement, a left spring fixed plate, a right force plate and a right rotating base plate. The utility model has no restrictions on measurement personnel: because the measuring tool cannot be loose, otherwise the measurement results will be inaccurate. Therefore, the original three-jaw chuck clamping measurement tooling method requires the operator to use a lot of force, and after replacing it with a lightweight tooling, only a little force is required compared to before; the machine adjustment time before measurement is greatly shortened: the newly designed tooling is the measurement zero position after installation, and there is no need for additional back and forth adjustment to find zero; the risk of the sensor being crushed is reduced: the new design uses screws, locating pins and magnets to stabilize the tooling, and its weight is lighter than the three-jaw chuck clamping tooling; the cost is lower: less raw materials are required to manufacture the new design, and the price is cheaper.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.
[0032] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.
[0033] In one embodiment, according to Figure 1-4 As shown, a rapid torque meter includes a detection plate 100; a detection position 110 is provided on the detection plate 100, and the detection position 110 is used to place a torsion spring 400 to be detected. A limiter 120 is provided next to the detection position 110, and the limiter 120 limits one end of the torsion spring 400. The detection plate 100 is provided with a rotating rod 200, and the rotating rod 200 is provided with a torque sensing shaft 210 and a torque display screen 220. The torque sensing shaft 210 limits the other end of the torsion spring 400.
[0034] The driving assembly is connected to the rotating rod 200. The driving assembly can drive the rotating rod 200 to rotate. When the rotating rod 200 rotates to a detection angle, the torque display screen 220 will display the torque value of the torsion spring 400 at the detection angle.
[0035] Specifically, the torsion spring 400 to be tested is placed in the testing position 110 on the testing plate 100, the limiter 120 limits one end of the torsion spring 400, the torque sensing shaft 210 limits the other end of the torsion spring 400, and the driving assembly drives the rotating rod 200 to rotate. When it rotates to the testing angle, the torque display screen 220 will display the torque value of the torsion spring 400 at the testing angle. If the torque value reaches the specified value of the product, it is a qualified product, otherwise it is an unqualified product.
[0036] Furthermore, by setting the detection position 110, the torsion spring 400 to be detected can be quickly placed in, and at the same time, the limit piece 120 and the torque sensing shaft 210 are clamped to the two ends of the torsion spring 400 to open the drive assembly for detection, which is convenient and fast. The torque display screen 220 is set to display the torque value of the torsion spring 400 at the detection angle at any time, which is clear and intuitive, and the detection efficiency is high.
[0037] In another embodiment, according to Figure 1-4 As shown, the drive assembly includes a rotary motor 300; an output shaft is provided on the rotary motor 300; a connecting rod is sleeved on the output shaft, and the rotary motor 300 drives the rotary rod 200 for rotation detection through the connecting rod. The connecting rod includes a first connecting rod 230 and a second connecting rod 240; one end of the first connecting rod 230 is sleeved on the output shaft, and the other end is connected to the second connecting rod 240, and the end of the second connecting rod 240 away from the first connecting rod 230 is limited and detachably connected to the rotary rod 200. The end of the second connecting rod 240 away from the first connecting rod 230 is provided with a snap-in position 241 to avoid air, and one end of the rotary rod 200 is limited to the snap-in position 241. The detection plate 100 is also provided with a rotation slot 140, and the second connecting rod 240 passes through the rotation slot 140 to connect to the rotary rod 200.
[0038] Specifically, the connecting rod can be a part that connects the rotating rod 200 for rotation, or it can be divided into a first connecting rod 230, and the second connecting rod 240 acts as a transmission rod to drive the rotating rod 200 to rotate. The end of the second connecting rod 240 is provided with a snap-in position 241 to avoid air, and one end of the rotating rod 200 is placed on the snap-in position 241 to achieve limiting, thereby driving the rotating rod 200 to rotate. The limiting member 120 and the torque sensing shaft 210 each limit one end of the torsion spring 400 to detect the torque value. The rotating groove 140 can have a scale so that the user can see the rotation angle more intuitively. At the same time, when a certain angle is reached, the rotating groove 140 can also be limited. It can be understood that using the torque sensing shaft 210 to detect torque is a mature existing technology, and displaying it through the torque display screen 220 after measurement is also a mature existing technology.
[0039] In another embodiment, according to Figure 1-3As shown, the detection position 110 is provided with an opening 111 that extends through the detection plate 100. A guide shaft 130 is disposed through the opening 111. One end of the guide shaft 130 is connected to the output shaft, and the other end is connected to the rotating rod 200. The guide shaft 130 and the rotating rod 200 are detachably connected, and a torsion spring 400 can be mounted on the guide shaft 130 for detection. One end of the guide shaft 130 is provided with a connecting protrusion 131, and one end of the rotating rod 200 is provided with a connecting groove 250. The connecting protrusion 131 is inserted into the connecting groove 250, achieving a detachable connection between the guide shaft 130 and the rotating rod 200. The connecting protrusion 131 and the connecting groove 250 have the same polygonal cross-sectional shape.
[0040] Specifically, the rotation of the output shaft can drive two places to rotate. First, it drives the connecting rod to rotate, and secondly, it drives the guide shaft 130 to rotate. The rotation of the connecting rod is the main one. Measuring the torque requires a large force. The rotation of the rotating rod 200 increases the power arm, and the rotating motor 300 can perform rotation measurement with a smaller force.
[0041] Furthermore, the guide shaft 130 and the rotating rod 200 are detachably connected, and after disassembly, the torsion spring 400 that has been tested can be taken out and a new torsion spring 400 to be tested can be put in.
[0042] Furthermore, the cross-sections of the connecting protrusion 131 and the connecting concave are polygonal, which can enable the guide shaft 130 to rotate and drive the rotating rod 200 to rotate. Together with the connecting rod, the rotating rod 200 can be rotated and measured.
[0043] In another embodiment, according to Figure 1-4 As shown, it also includes a bottom plate 500, on which a rotating motor 300 is provided, and a support column 510 is provided between the detection plate 100 and the bottom plate 500. Specifically, there are multiple support columns 510 to support the detection plate 100 and the bottom plate 500.
[0044] The above description further details the present invention in conjunction with specific preferred embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. A person skilled in the art of the present invention will appreciate that its architecture is flexible and adaptable, allowing for the development of a series of products without departing from the present invention's concept. Simple deductions or substitutions should be considered within the scope of patent protection for the present invention as defined by the submitted claims.
