[0021] Embodiment:
[0022] The embodiment of the present application discloses a shaft forging with an end adjusting structure, please refer to Figures 1-4 , comprising a shaft body 1, an end adjusting structure 2 and a locking device 3; the end adjusting structure 2 comprises an adjustable sleeve 21 and an adjusting thread 22, the adjustable sleeve 21 is connected with the shaft body 1 through the adjusting thread 22, the locking device 3 is used for fixing the position of the adjustable sleeve 21, the shaft body 1 is provided with a scale mark 12 at the end, the shaft body 1 is the basic component of the present application, which is usually a cylindrical forging, used for transmitting torque or supporting rotating parts, made of high-strength alloy steel or high-quality carbon steel, and subjected to forging and heat treatment to improve mechanical properties, both ends of the shaft body 1 are provided with external threads for cooperating with the adjusting thread 22 of the end adjusting structure 2, the end adjusting structure 2 is the core component for realizing the size or shape adjustment of the end of the shaft forging, mainly composed of the adjustable sleeve 21 and the adjusting thread 22, and is a hollow cylindrical structure with an inner diameter matched with the outer diameter of the shaft body 1, the locking device 3 is used for fixing the position of the adjustable sleeve 21 to prevent it from loosening during work. Its main components include a locking nut 31 and a stop washer 32.
[0023] The inner wall of the adjustable sleeve 21 away from the shaft body 1 is provided with a guide groove 211, and the adjusting thread 22 is a fine thread. The guide groove 211 is located on the side of the inner wall of the adjustable sleeve 21 away from the shaft body 1, that is, close to the opening end of the sleeve. The guide groove 211 is an axial straight groove with a rectangular or trapezoidal cross-sectional shape, and its width is slightly larger than the width of the protrusion on the outer wall of the shaft body 1 to ensure smooth movement of the sleeve. The number of guide grooves 211 is usually four, which are evenly distributed on the inner wall of the sleeve body to improve the stability of the guide. The guide groove 211 cooperates with the protrusion on the outer wall of the shaft body 1 to prevent the adjustable sleeve 21 from rotating circumferentially during adjustment and ensure the stability of the adjustment. Through the guiding effect of the guide groove 211, the adjustable sleeve 21 can only move axially, avoiding the adjustment error caused by circumferential rotation. The design of the guide groove 211 increases the structural strength of the sleeve body to prevent deformation or damage during adjustment. The design of the fine thread converts the rotary motion into axial movement, and the axial movement amount is small after one rotation, which improves the sensitivity and accuracy of the adjustment. The contact area of the fine thread is large, which can withstand a large axial load to ensure the stability and reliability during adjustment. The guide groove 211 ensures that the adjustable sleeve 21 can only move axially, and the adjusting thread 22 converts the rotary motion into axial movement. The two work together to achieve precise adjustment. Through the guiding effect of the guide groove 211, the adjustment process of the adjustable sleeve 21 is smoother, reducing the adjustment resistance and time. The design of the guide groove 211 and the adjusting thread 22 increases the structural strength and stability of the sleeve body to prevent deformation or damage during adjustment.
[0024] The locking device 3 comprises a locking nut 31 and a stop washer 32, and the stop washer 32 is located on the side of the locking nut 31 close to the end adjustment structure 2. The locking nut 31 is made of high-strength alloy steel or high-quality carbon steel, and is heat treated to improve hardness and wear resistance. The inner thread of the locking nut 31 matches the outer thread of the shaft body 1, and the thread type is fine thread with the same pitch as the adjustment thread 22 to ensure smooth rotation of the locking nut 31. The shape of the locking nut 31 is hexagonal or circular. The hexagonal design facilitates locking operation with a wrench, and the circular design is suitable for space-limited occasions. By rotating the locking nut 31, the end face of the locking nut 31 is pressed against the locking surface of the adjustable sleeve 21 to prevent the adjustable sleeve 21 from moving axially during operation. The locking nut 31 provides pre-tightening force by rotation to ensure that the connection between the adjustable sleeve 21 and the shaft body 1 is tight and reliable. The stop washer 32 is made of spring steel or stainless steel and has good elasticity and corrosion resistance. The stop washer 32 is an open washer with an inner diameter slightly smaller than the outer diameter of the locking nut 31 and an outer diameter slightly larger than the outer diameter of the locking nut 31. The opening of the washer is provided with a protrusion for clamping into the groove of the locking nut 31 or the key groove of the shaft body 1. The stop washer 32 is located on the side of the locking nut 31 close to the end adjustment structure 2, i.e. between the locking nut 31 and the adjustable sleeve 21.
[0025] The implementation principle of the embodiment is: comprising a shaft body 1, an end adjustment structure 2 and a locking device 3. The shaft body 1 is provided with an end adjustment structure 2 at each end, and the end adjustment structure 2 comprises an adjustable sleeve 21 and an adjustment thread 22. The adjustable sleeve 21 is connected to the shaft body 1 through the adjustment thread 22, and rotating the adjustable sleeve 21 can change its position relative to the shaft body 1. The locking device 3 comprises a locking nut 31 and a stop washer 32 for fixing the position of the adjustable sleeve 21. The inner wall of the adjustable sleeve 21 is provided with a guide groove 211, and the outer wall of the shaft body 1 is provided with a protrusion matching the guide groove 211 to ensure stability during adjustment. The adjustment thread 22 is a fine thread to improve adjustment accuracy. The shaft body 1 is provided with a scale mark 12 at the end to facilitate accurate adjustment of the position of the adjustable sleeve 21.
[0026] The above are preferred embodiments of the present application, but do not limit the protection scope of the present application, therefore: any equivalent changes made in structure, shape, principle, etc. according to the present application should be covered within the protection scope of the present application.
