Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a torque sensor that is easy to install. Background Technology

[0002] Torque sensors are important devices for measuring the torque of rotating shafts and are widely used in industrial automation, automotive testing, aerospace and other fields.

[0003] Existing torque sensors typically connect to an external measuring shaft via flange or key connections. These installation methods require bolting or interference fits to connect the measuring shaft and the torque sensor, resulting in low installation efficiency. This application provides a torque sensor that is easier to install, thus solving the aforementioned problems. Utility Model Content

[0004] Based on the above situation, the main purpose of this utility model is to provide a torque sensor that is easy to install, so as to solve the problem that existing torque sensors all require connecting the measuring shaft and the torque sensor by tightening bolts or interference fit, resulting in low installation efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An easy-to-install torque sensor includes a sensor body and a mounting assembly;

[0007] The mounting assembly includes a threaded tube and a plug;

[0008] The threaded tube can be connected to the input end and / or output end of the sensor body, and the end of the threaded tube is provided with a tapered groove.

[0009] The threaded tube has multiple through grooves on its circumference. The insert block is slidably connected to the through grooves. One side of the insert block has an inclined surface. The threaded tube is externally threaded with a sleeve, which can abut against the inclined surface.

[0010] Preferably, the mounting assembly further includes a connecting pipe, which is fixed to the sensor body.

[0011] Preferably, a sliding groove is provided on one side of the through groove, and a slider is fixed on one side of the insert block, the slider being slidably connected within the sliding groove.

[0012] Preferably, a receiving groove is formed on the side of the through groove away from the slide groove, a connecting block is fixedly connected to the side of the insert block away from the slider, a spring is fixed in the receiving groove, and the spring and the connecting block are fixed together.

[0013] Preferably, the conical groove includes a first conical segment and a second conical segment, the first conical segment being located above the second conical segment, and the cone angle of the first conical segment being greater than the cone angle of the second conical segment.

[0014] Preferably, the plurality of through slots are evenly arranged along the circumferential direction of the threaded tube.

[0015] The beneficial effects of this utility model are as follows: When installing the shaft at the input end and / or output end of the sensor body, the shaft is first inserted into the threaded tube, and the sleeve is gradually rotated. The movement of the sleeve can push the insert block to move inward, thereby enabling the insert block to press against the shaft inside, and clamping the shaft inside the threaded tube, thus improving the installation efficiency. In addition, multiple insert blocks arranged along the axial direction of the threaded tube can ensure the concentricity of the shaft and the sensor body, ensuring the detection accuracy.

[0016] Other beneficial effects of this utility model will be explained in detail through the introduction of specific technical features and technical solutions in the specific embodiments. Those skilled in the art should be able to understand the beneficial technical effects brought about by the technical features and technical solutions through the introduction of these technical features and technical solutions.

[0022] The present invention will now be described based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.

[0023] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0024] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0025] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] Reference Figure 1-3 This utility model provides an easy-to-install torque sensor, including a sensor body 1 and a mounting component 2. The mounting component 2 can be set at the input end or the output end of the sensor body 1 for quick connection between the sensor body 1 and the shaft to which the torque is measured.

[0027] Mounting assembly 2 includes a connecting pipe 21, a threaded pipe 22, and a plug 25. The connecting pipe 21 and the threaded pipe 22 are both coaxially arranged with the sensor body 1, and the ends of the connecting pipe 21 and the threaded pipe 22 are fixed. The connecting pipe 21 is sleeved and fixed to the input end or output end of the sensor body 1.

[0028] The threaded tube 22 has a tapered groove 24 at its opening away from the connecting tube 21. The tapered groove 24 guides the shaft to be inserted into the mounting assembly 2 and maintains coaxiality with the sensor body 1. Multiple through grooves 221 are formed on the side circumference of the threaded tube 22, evenly arranged along its circumference. Each through groove 221 has a sliding block 25 connected to it. The sliding direction of the block 25 is radial to the threaded tube 22. The inner side of the block 25 is arc-shaped. When the shaft is inserted into the threaded tube 22 and the connecting tube 21, the block 25 moves inward to press against the shaft, providing multi-angle limiting and clamping.

[0029] A sleeve 26 is externally threaded onto the threaded tube 22. Rotating the sleeve 26 allows it to move along the axis of the threaded tube 22. Each insert 25 has a bevel 253 on the side near the connecting tube 21, allowing the sleeve 26 to contact the bevel 253. Rotating the sleeve 26 moves it along the axis of the threaded tube 22, abutting against the bevel 253, thus pushing the insert 25 towards the inside of the threaded tube 22. When installing the shaft at the input and / or output ends of the sensor body 1, the shaft is first inserted into the threaded tube 22. Gradually rotating the sleeve 26 pushes the insert 25 inward, allowing it to press against the shaft inside the threaded tube 22, thus securing the shaft within the threaded tube 22 and improving installation efficiency. Furthermore, the multiple inserts 25 arranged axially along the threaded tube 22 ensure the concentricity of the shaft and the sensor body 1, guaranteeing detection accuracy.

[0030] As one embodiment, a sliding groove 222 is provided on one side of the through groove 221. The extension direction of the sliding groove 222 is the same as the radial direction of the threaded tube 22. A slider 252 is fixed on the upper side of the insert block 25. The slider 252 is slidably connected in the sliding groove 222, which can improve the movement stability of the insert block 25.

[0031] As one embodiment, a receiving groove 223 is provided on the side of the through groove 221 away from the slide groove 222, and a connecting block 251 is fixedly connected to the side of the insert block 25 away from the slider 252. A spring is fixed in the receiving groove 223. Under normal conditions, the spring can push the insert block 25 to move towards the outside of the threaded tube 22, so that the insert block 25 can be reset after the shaft is disengaged.

[0032] As one embodiment, the tapered groove 24 includes a first tapered segment 241 and a second tapered segment 242. The first tapered segment 241 is located above the second tapered segment 242, and the cone angle of the first tapered segment 241 is larger than that of the second tapered segment 242. The first tapered segment 241 is used for guidance, and the second tapered segment 242 is used for positioning the shaft, thereby improving the concentricity of the shaft and the sensor body 1. It should be noted that the tapered groove 24 may also include more tapered segments, or a single tapered segment is sufficient as long as it can achieve the function of improving the concentricity of the shaft connection.

[0033] The implementation principle of this utility model is as follows: When installing the shaft at the input end and / or output end of the sensor body 1, first insert the shaft into the threaded tube 22, and gradually rotate the sleeve 26. The movement of the sleeve 26 can push the insert 25 to move inward, thereby enabling the insert 25 to press against the shaft inside, and clamp the shaft inside the threaded tube 22, improving the installation efficiency. In addition, the multiple inserts 25 arranged along the axial direction of the threaded tube 22 can ensure the concentricity of the shaft and the sensor body 1, and ensure the detection accuracy.

[0034] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0035] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions made by those skilled in the art regarding the above details will be included within the scope of the claims of this utility model.
