[0047] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0048] See also Figure 1 The embodiment of the present application provides a balancing nut 100, which is used to be installed on an external workpiece to adjust the output end of the external workpiece to a balanced state, and includes a main body 10, a stopper 20 and a plurality of balancing components 30. For example, the external workpiece may be a grinding wheel set, and the number of the balancing components 30 may be two or more.
[0049] See also Figure 1 , Figure 2 and Figure 3The main body 10 is provided with a threaded hole 11 and an annular groove 12. The threaded hole 11 penetrates the main body 10 along the axial direction of the main body 10. The annular groove 12 is provided at one end surface of the main body 10 and is provided around the threaded hole 11. The annular groove 12 includes a bottom wall 121 and a first groove wall 122 and a second groove wall 123 connected to opposite ends of the bottom wall 121. The first groove wall 122 is inclined relative to the central axis of the threaded hole 11. The stopper 20 is received in the annular groove 12 and abuts against the second groove wall 123. A plurality of balancing components 30 are arranged in the annular groove 12 at intervals around the threaded hole 11, and each balancing component 30 includes a balancing slider 31 and a locking member 32. The balancing slider 31 is slidably arranged in the annular groove 12, and the two sides of the balancing slider 31 are respectively abutting matching surface 311 and arc surface 312, the abutting matching surface 311 is always facing the first groove wall 122, the arc surface 312 abuts against the limiter 20, and the locking member 32 is penetrated through the balancing slider 31 along the axial direction of the main body 10 and is threadedly connected with the balancing slider 31, and the locking member 32 is used to move in the direction close to the bottom wall 121 under the action of external force, so as to push the balancing slider 31 to abut against the first groove wall 122 through the abutting matching surface 21. Exemplarily, the locking member 32 can be a locking screw.
[0050] In the above-mentioned balancing nut 100, the operator first installs the main body 10 to the output end of the external workpiece through the threaded hole 11, and then quickly adjusts the multiple balancing sliders 31 to different azimuth positions in the annular groove 12 to adjust the center of gravity of the external workpiece to a balanced state. Finally, under the action of external force, the multiple locking members 32 all move in a direction close to the bottom wall 121 to push the corresponding balancing sliders 31 to abut against the first groove wall 122 through the abutting matching surface 21, so as to lock the multiple balancing sliders 31 into the annular groove 12, thereby realizing the rapid adjustment of the center of gravity of the external workpiece to a balanced state, thereby improving the adjustment efficiency. In addition, the balancing nut 100 has a simple structure and reduces the cost of use.
[0051] It is understandable that the setting position of the first groove wall 122 can be adjusted according to the use requirements of the balance nut 100. The first groove wall 122 can be the groove wall of the annular groove 12 adjacent to the threaded hole 11, or the groove wall of the annular groove 12 away from the threaded hole 11.
[0052] See also Figure 3 In some embodiments, the width of the notch of the annular groove 12 along the radial direction of the main body 10 is greater than the width of the end of the balancing slider 31 close to the bottom wall 121 along the radial direction of the main body 10. The width of the notch of the annular groove 12 along the radial direction of the main body 10 is a first width A, and the width of the end of the balancing slider 31 close to the bottom wall 121 along the radial direction of the main body 10 is a second width B.
[0053] In this way, by setting the specific structure of the annular groove 12 and the balancing slider 31 mentioned above, the annular groove 12 can provide a sufficiently large installation opening for the installation operation of the balancing slider 31, so that the operator can install the balancing slider 31 into the annular groove 12 easily.
[0054] In some embodiments, the sum of the width of one end of the balancing slider 31 close to the bottom wall 121 along the radial direction of the main body 10 and the width of the stopper 20 is smaller than the width of the bottom wall 121 along the radial direction of the main body 10, and is larger than the width of the notch of the annular groove 12 along the radial direction of the main body 10. The width of the stopper 20 is the third width C, and the width of the bottom wall 121 along the radial direction of the main body 10 is the fourth width D.
[0055] In this way, by setting the specific structure of the above-mentioned annular groove 12, balancing slider 31 and limiting member 20, a certain gap can be formed between the annular groove 12 and the balancing slider 31 located in the annular groove 12, so as to facilitate the stable sliding of the balancing slider 31 in the annular groove 12, and at the same time prevent the balancing slider 31 and the limiting member 20 from falling out of the annular groove 12 during the adjustment operation.
[0056] See also Figure 2 In some embodiments, the upper surface 313 of the balancing slider 31 and the lower surface 314 of the balancing slider 31 are transitionally connected to the abutting matching surface 311 and the arc surface 312 through an arc structure 315 .
[0057] In this way, by providing the above-mentioned arc structure 315, when the balance nut 100 is assembled, the balance slider 31 can be avoided between the arc structure 315 and the main body 10 to prevent collision between the main body 10 and the balance slider 31, thereby improving the installation stability of the balance nut 100.
[0058] See also Figure 3 In some embodiments, the main body 10 is further provided with an avoidance groove 13 , which is provided at one end of the main body 10 away from the annular groove 12 and located at the opening of the threaded hole 11 .
[0059] In this way, by providing the above-mentioned avoidance groove 13 , it is possible to avoid collision between the main body 10 and the external processed part when the main body 10 is installed on the external processed part, prevent damage to the balancing nut 100 , and improve the service life of the balancing nut 100 .
[0060] See also Figure 2 In some embodiments, the main body 10 is further provided with a plurality of weight-reducing grooves 14 , and the plurality of weight-reducing grooves 14 are all provided on the bottom wall 121 and are arranged at equal intervals around the threaded hole 11 .
[0061] In this way, by providing the above-mentioned weight-reducing groove 14 , the weight of the main body 10 can be reduced, so that the center of gravity shift is more sensitive when adjusting the position of the balancing slider 31 , thereby improving the adjustment accuracy of the balancing nut 100 .
[0062] In some embodiments, the main body 10 is further provided with scale lines 15 , which are arranged around the threaded hole 11 and are located on the same side of the main body 10 as the annular groove 12 .
[0063] Thus, by providing the above-mentioned scale lines 15 , it is helpful for the operator to accurately adjust the positions of the plurality of balancing sliders 31 , thereby simplifying the balancing adjustment process and further improving the adjustment efficiency and adjustment accuracy.
[0064] In some embodiments, a working groove 321 is provided at one end of the locking member 32 away from the bottom wall 121, and the working groove 321 is used to clamp an external working member. For example, the working groove 321 can be a cross groove or a slotted groove, and the external working member can be a locking tool, such as a screwdriver.
[0065] In this way, by providing the working groove 321 at the end of the locking member 32, the external working piece can be clamped, which makes it convenient for the external working piece used by the operator to act on the working groove 321, thereby improving the convenience of operation.
[0066] In some embodiments, a chamfer 322 is formed at one end of the locking member 32 away from the working slot 321 .
[0067] Thus, by providing the chamfer 322 , when the balancing nut 100 is assembled, the locking member 32 can be easily inserted into the balancing slider 31 , thereby avoiding collision between the locking member 32 and the balancing slider 31 .
[0068] In some embodiments, the outer surfaces of the main body 10, the stopper 20 and the plurality of balancing components 30 are all covered with a protective layer. For example, the protective layer may be a titanium nitride coating, a tungsten nitride coating or the like.
[0069] In this way, by covering the outer surface of each component of the balancing nut 100 with a protective layer, the mechanical properties of the balancing nut 100, such as corrosion resistance and hardness, can be improved, making the balancing nut 100 suitable for complex application environments, thereby increasing the service life of the balancing nut 100.
[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
