[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0036] Example 1
[0037] See attached document Figures 1-3 A torque measuring instrument includes: an upper housing 1, a lower housing 2, a clamping cover 3, a clamping mechanism, a measuring element, and an indicating component. During the torque measurement process, when the upper housing 1 is rotated, the measuring element can apply torque to the component under test, thereby measuring the torque of the component under test.
[0038] Specifically, the lower housing 2 is connected to the upper housing 1 via a connector in a relative rotational configuration; the connector enables the upper housing 1 and the lower housing 2 to rotate relative to each other. A clamping cover 3 is detachably mounted on the lower housing 2; a clamping mechanism is mounted on the clamping cover 3 for clamping the part to be measured; the detachable design of the clamping cover 3 facilitates the replacement of the clamping structure with a suitable one according to the size of the part to be measured. A measuring element is mounted between the upper housing 1 and the connector; an indicating component is mounted on the upper housing 1 to display the torque reading; the measuring element directly acts on the torque detection, while the indicating component visually presents the measurement result. Each part has a clear division of labor, ensuring the orderly progress of the measurement process.
[0039] In one embodiment of this utility model, the connecting member is a connecting screw 17. Bearings a18 and b19 are mounted on the outer wall of the connecting screw 17, and the outer wall of the connecting screw 17 is fixedly connected to the inner rings of bearings a18 and b19, respectively. The outer rings of bearings a18 and b19 are fixedly connected to the upper housing 1, and the bottom end of the connecting screw 17 is threadedly connected to the lower housing 2. The bearings a18 and b19 reduce rotational friction between the connecting screw 17 and the upper housing 1, ensuring smooth relative rotation. The threaded connection facilitates the assembly and disassembly of the connecting screw 17 and the lower housing 2, while ensuring connection stability and preventing loosening during measurement that could affect data accuracy.
[0040] In one embodiment of this utility model, the clamping cover 3 is threaded onto the lower housing 2, and the bottom of the clamping cover 3 is conical. The threaded mounting structure allows for quick disassembly and installation of the clamping cover 3, facilitating subsequent maintenance or replacement with clamping covers of different specifications. The conical bottom design can accommodate some test components requiring conical mounting, while also enhancing the structural stability of the bottom of the clamping cover 3 and reducing shaking during measurement.
[0041] In one embodiment of this utility model, the clamping mechanism includes three clamping blocks 6 arranged in an array inside the clamping cover 3, with a spring a7 installed between adjacent clamping blocks 6. The three arrayed clamping blocks 6 can clamp the component to be tested, ensuring uniformity and stability of the clamping. The spring a7 has an elastic reset function; when placing or removing the component to be tested, the spring a7 can drive the clamping blocks 6 to adjust their position to accommodate components of different sizes, while preventing excessive clamping force from damaging the component.
[0042] In one embodiment of this utility model, the measuring element includes a coil spring 13, an mounting ring 15 is installed on the inner wall of the upper housing 1, and a screw 16 is threaded onto the outer wall of the upper housing 1. The screw 16 is used to lock and fix the mounting ring 15. A connecting post 14 is installed on the mounting ring 15. One end of the coil spring 13 is fixedly connected to the outer wall of the connecting screw 17, and the other end of the coil spring 13 is fixedly connected to the outer wall of the connecting post 14. The coil spring 13 is the core torque sensing component. When the upper housing 1 rotates, the coil spring 13 deforms and generates a reaction force, which is related to the torque of the component being measured. The mounting ring 15 provides a mounting carrier for the connecting post 14. The screw 16 can be fixed in position by tightening the mounting ring 15, preventing displacement of the mounting ring 15 during measurement and thus avoiding measurement errors. The connecting post 14 is used to stably connect the coil spring 13 and the mounting ring 15, ensuring effective force transmission.
[0043] In one embodiment of this utility model, a through groove is provided on the outer wall of the upper housing 1, and a locking pin 25 is slidably connected to the inner wall of the through groove. A button 27 is fixedly installed on the end wall of the locking pin 25, and a spring b26 is sleeved on the outside of the locking pin 25. One end of the spring b26 is fixedly connected to the inner wall of the through groove, and the other end is fixedly connected to the end wall of the button 27. The locking pin 25 can slide within the through groove to lock the relative position of the upper housing 1 and the lower housing 2 before or after measurement, preventing the components from rotating arbitrarily when not in a measurement state. The button 27 allows the operator to control the sliding of the locking pin 25. The spring b26 can automatically reset the locking pin 25 after the button 27 is pressed, achieving quick locking and unlocking and improving operational convenience.
[0044] In one embodiment of this utility model, the indicating component includes a top cover 4, a rotating column 8, a mounting cylinder 9, an indicating needle 10, and a dial 12. The top cover 4 is mounted on the top of the upper housing 1; the dial 12 is mounted on the inner wall of the upper housing 1; the mounting cylinder 9 is rotatably connected to the center of the outer wall of the dial 12; the rotating column 8 is mounted on the mounting cylinder 9; and the indicating needle 10 is rotatably mounted on the mounting cylinder 9. The top cover 4 is provided with a transparent acrylic plate, which protects the internal components of the indicating component from dust and impurities. The dial 12 is marked with a torque scale to provide a reference for reading. The mounting cylinder 9 serves as the mounting carrier for the rotating column 8 and the indicating needle 10. Its rotation around the center of the dial 12 drives the indicating needle 10 to rotate synchronously. The rotating column 8 can be externally operated to drive the mounting cylinder 9 to rotate, thereby adjusting the position of the indicating needle 10 and ensuring accurate reading.
[0045] In one embodiment of this utility model, a limiting block 11 is installed on the bottom wall of the upper cover 4, and the limiting block 11 is located on the rotation trajectory of the indicator needle 10. The limiting block 11 can limit the maximum rotation angle of the indicator needle 10, preventing the coil spring 13 from being damaged due to excessive rotation of the upper housing 1, and at the same time preventing the indicator needle 10 from rotating excessively away from the scale area of the dial 12, ensuring that the reading is always within the observable range.
[0046] In one embodiment of this utility model, a reading indicator ring 5 is rotatably mounted on the bottom of the upper housing 1, and a magnet 22 is fixedly installed on the bottom wall of the upper housing 1. The reading indicator ring 5 is attracted and fixed to the magnet 22. Torque scale lines are respectively provided on the outer walls of the upper housing 1 and the lower housing 2. The reading indicator ring 5 can be rotated to cooperate with the scale lines on the upper housing 1 and the lower housing 2 to assist in reading the torque value. The magnet 22 magnetically attracts and fixes the reading indicator ring 5, which not only ensures the stability of the reading indicator ring 5 during reading, but also allows the operator to adjust its position according to the measurement needs. The scale line design on the double housings can realize multi-angle readings, improving the flexibility of use.
[0047] In one embodiment of this utility model, a limiting pin 20 is fixedly installed on the bottom wall of the upper housing 1, and two limiting posts 24 are fixedly installed on the inner wall of the lower housing 2. The two limiting posts 24 are respectively located within the moving path of the limiting pin 20. A positioning pin 23 is fixedly installed on the top wall of the lower housing 2, and a ejector pin 21 is installed on the bottom wall of the upper housing 1. The limiting pin 20, in cooperation with the two limiting posts 24, can limit the maximum relative rotation angle between the upper housing 1 and the lower housing 2, preventing damage to components due to excessive rotation. The positioning pin 23 and the ejector pin 21 can play a positioning role during device assembly or reset, ensuring that the upper housing 1 and the lower housing 2 are quickly aligned to their initial positions, reducing debugging time.
[0048] In this embodiment, the working principle of the device is as follows: First, according to the size and shape of the component to be tested, a suitable clamping cover 3 is selected and fixed to the lower housing 2 by threaded installation. Then, the button 27 is pressed, which drives the locking pin 25 to compress the spring a26 and retract into the through slot, thereby releasing the locking state between the upper housing 1 and the lower housing 2. The component to be tested is placed in the clamping cover 3, and the three clamping blocks 6 clamp the component to be tested under the elastic action of the spring a7. At the same time, the rotating block 3 presses against the block 6, thereby further clamping the component to be tested.
[0049] Then release button 27, rotate reading indicator ring 5 to align it with the initial scale line on the upper housing 1, and fix it by magnet 22;
[0050] Next, the upper housing 1 is slowly rotated. The upper housing 1 drives the mounting ring 15 and the connecting column 14 to rotate synchronously. The connecting column 14 pulls the disc spring 13 to deform. The reaction force generated by the disc spring 13 is transmitted to the lower housing 2 through the connecting screw 17, thereby applying torque to the component to be tested.
[0051] Meanwhile, the rotation of the upper housing 1 will drive the limiting pin 20 to move along the inner wall of the lower housing 2. When the limiting pin 20 contacts one of the limiting posts 24, the rotation of the upper housing 1 will stop. At this time, observe the pointer 10 on the dial 12 and, in conjunction with the scale lines on the outer walls of the upper housing 1 and the lower housing 2 and the position of the reading indicator ring 5, read and record the torque value of the component under test. After the measurement is completed, rotate the upper housing 1 in the opposite direction to the initial position. The positioning pin 23 and the top pin 21 are aligned to achieve positioning. The coil spring 13 returns to its deformation. Finally, the component under test is taken out, completing one torque measurement process.
[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
